3 4指南各项目标及建议

3 4指南各项目标及建议最近在做“3 4指南各项目标及建议”这块,有点心得要说说。
这“3 4指南”啊,目标看起来就挺复杂的。
先说这其中的3个大目标吧。
我觉得第一个目标就是得理清框架,就像建房子得有个蓝图一样。
我刚开始的时候就很懵,完全不知道从哪儿下手。
有一次啊,做一个小项目就得按照这个3 4指南来,结果第一步就卡壳了。
我当时就瞎搞,到处乱找资料,完全没有章法。
后来我觉得啊,对于这种要理清框架的目标,一开始就得静下心来好好研究指南的介绍文档,哪怕是枯燥也得看进去。
虽然这个建议听着简单,但做起来真不容易。
还有就是多向有经验的人请教,我就找了个以前做过类似的前辈,他一点拨,我就感觉思路清晰多了。
不过呢,我也知道这个方法有局限性,因为不是随时都能找到这么合适的人请教。
替代方案嘛,就是在网络论坛上搜搜相关的分析帖子。
我感觉第二个目标呢,是操作起来要细致。
我记得我在做某个环节的时候,因为太粗糙了,导致后面很多流程都得返工。
这就好比做饭,盐放多了想补救就很难了。
所以我得出的经验就是,每一步操作,都要先在脑子里过一遍可能会出现的问题。
比如说,我后来会在做之前先写一个小的步骤大纲,然后对照着这个大纲一一执行,每执行完一步就检查一下。
但是这个也有不好的地方,就是太费时间。
那替代的方法呢,就是和团队里的小伙伴互相检查,这样说不定能发现自己没看到的问题。
还有啊,第三个目标,我觉得是得有灵活应变的能力。
行业里变化太快了,这3 4指南虽然明确了方向,但难免会遇到新情况。
我有次遇到突发问题,就按照老的指导死板地做,结果亏大了。
当时我就意识到,要根据实际情况,灵活地运用指南里的要求。
我是怎么做的呢?我会定期去关注市场动态呀或者行业新规则之类的东西。
你想啊,就像开车似的,路上有个坑,你得绕开啊,不能就傻愣愣地往前开。
不过呢,关注这些信息也很耗费精力。
所以还可以参加一些同行的交流会,别人遇到新情况的解决方式可能会给你带来启发。
再说说这里面的4个小目标吧。

新标准大学英语(第二版)视听说3听力原文及选择题整理

新标准⼤学英语(第⼆版)视听说3听⼒原⽂及选择题整理⼤学英语三视听说3第⼆版听⼒材料以及选择排序题整理U1Outside view1-2原⽂Presenter: Happiness is not what most students have in mind when they think of school. Yet a school in Germany has developed a novel way to raise the morale of its students, by teaching happiness in classes. Students at Heidelberg’s Willy Hellpach School of Economics are learning how to achieve happiness as an official subject, alongside mathematics and languages. This is the first school in Germany to develop a happiness course, intended for 17- to 19-year-olds preparing for university entrance exams. Ernst Fritz-Sch ubert, the school’s principal, is on a mission to change things.Ernst: It was my idea –I’ve been at this school for 31 years, and I feel that school and happiness have to be reunited. These are two terms which are not considered together, because one does not connect school with happiness. In some cases school comes behind the dentist on the popularity scale and we should try to push schools’ popularity a bit. It has been proved by science that a happy student can learn more than an unhappy one. Unhappy students can concentrate for a while but do not use all their potential. The happiness classes are intended to help students fulfill their potential. They will help the students live happy and prosperous lives.Presenter: The classes aim to help students in achieving a positive state of mind, by using all their own resources and boosting their self-esteem. In addition, they hope classes will increase self-awareness and physical comfort. Happiness classes are also intended to make students more aware about their environment and society as a whole. During classes students are encouraged to express themselves and observe their peers’ behaviour. The classes are taught by Bjoern Bonn, an actor and visiting lecturer.Outside view 3-4原⽂Bjoern: One of the exercises I do is to have one of the students walk across the classroom, with the others copying his walk. Through this exercise, I hope they learn something about themselves. Why do I move like this? How do others see my way of walking? I hope that with a higher body awareness they ideally – of course it will take time – achieve a higher self-consciousness which could lead to happiness. Wolfgang: We give these classes to students to help them find happiness. Now the question is: How do I define happiness? Happiness is for example a strengthening of the personality. We are providing helpful suggestions to make stronger people. People that ask "Who am I as a person? Am I really happy?" Pascal: It takes time and everybody has to find happiness for themselves. You cannot go into a coaching lesson and say, “Teach me happiness.” One can only get indications from teachers or the visiting lecturers. There are also happiness scientists, if we could talk to one of those I’m sure he would have some hints.Yosma: You would think that the teachers are writing definitions on the board. Not true. Those who want happiness have to find it for themselves, you cannot really learn that.Presenter: So what does it take to be happy, and can you learn it at school?News report 原⽂1、Recent statistics show that young people are heading abroad in ever-increasing numbers – at least temporarily. Experts say spending time overseas can give students an advantage when looking for a job after they graduate. Employers are attracted to candidates with international experience and global skills.Audrey Morgan, a graduate of the University of Pennsylvania, was inspired to learn Spanish. She decided to spend a semester studying in Spain during her junior year. That experience led to the job she has today, as an engineer for a technology company with offices all over the world.Her current work project involves working closely with an organization in Spain, and her fluent Spanishmeans she is able to translate documents from Spanish to English and communicate with her Spanish co-workers. She hopes to work in one of her company’s international offices within a few years.It’s up to students to decide how long they want to spend studying overseas. They may go for a year, a semester or a summer. However long or short the time, they are sure to have a rewarding experience. Q1: How does studying abroad give students an advantage in the job hunt?A. Employers are looking for candidates who have global skills.Q2: How much time should students spend overseas?D. Any amount.2、Potential college students are once again facing the annual ordeal of college admissions. Each year many university-bound students in the US fear writing the required college application essay. However, it is a chance for students to show admission officers who they really are beyond grades and test scores.A strong, well-written essay can make a difference when universities are choosing between talented applicants.Each university has its own set of essay prompts and questions that students can answer. They want students to reveal their best qualities and interests, show their creativity, as well as their writing skills. One university’s sample prompt is: “Describe the world you come from –for example, your family, community or school –and tell u s how your world has shaped your dreams and aspirations.” Or a question simply asking “What makes you happy?”Some students find that the essay is one of the most challenging things they’ve written. They have to think about issues that really matter to them, what their values are and what their experiences mean to them. Usually, by the end of the process, students will have discovered a lot about themselves that they didn’t know before.Q1: What do we learn about the college application essay from the news report?D. Students are required to submit an essay to universities.Q2: How do students feel about writing the college application essay?B. Students are afraid of writing the essay.Inside view1、Interviewer: Can you tell me … how do you think you have changed as you have matured? What things have had a major influence on you?Speaker 1: Well, let me think ... I suppose going to university had a big impact on my life. It made me much more open-minded. I met so many different types of people there with weird and wonderful ideas and it changed the way I see the world. I’m much more tolerant now ... It made me a more rounded person.Interviewer: Great ... And has any particular person had a central role in forming your character? Speaker 1:I guess that’d ha ve to be my grandfather. I was very close to him and he taught me to stand up for my beliefs. He was always telling me about his ...Interviewer: So what people or events have had an impact on your life?Speaker 2: I think that travelling in my gap year made me grow up and see both the beauty of the world and, well ... just the generosity of ordinary people. I travelled a lot around Asia and you know, I found that in some of the poorest countries, like Cambodia and Laos, people share whatever little they have, and they possess a real joy for life. It’s probably made me a less selfish person.Interviewer: Interesting. ... So you would recommend that young people take a gap year to discover themselves and the world?Speaker 2: Definitely. It gives you an opportunity to learn about the world beyond the one you grew up in and I found it really …Interviewer: Could you tell me what things in your life have had the greatest influence in forming your personality?Speaker 3: Well ... a couple of years ago I was on a reality TV show where a group of young people all lived in a house together. Each week someone was voted off by the audience. I got down to the final three! I suppose being on the show and seeing how the other contestants behaved made me realize howselfis h and spiteful some people can be just to get what they want. I also realized it’s best to just be yourself in life. If you pretend to be someone different people will eventually see through the lies. Interviewer: Right ... And how did you feel when you were eventually voted off?Speaker 3: Relieved, to be honest with you. But you know … a slight regret that I didn’t win because I kind of ...Interviewer: So can you tell me, what one thing do you think has had the biggest impact on your life? Speaker 4: Hmm, that’s a difficult question. But I think helping victims of the tsunami in 2004 had a very great impact on me. I’m half Thai and I’d just arrived in Thailand for a family Christmas holiday. When I heard the news I knew I had to help –you couldn’t not. I ended up acting as an interpreter for a group of volunteer doctors. It was an incredibly difficult time but you know, even in the middle of such a horrific tragedy there is still a huge amount of genuine human kindness.Interviewer: That’s amazing! And ha s it changed the way you view your future ...1. How did going to university change Speaker 1?C. It made him more open-minded.2. How did travelling change Speaker 2?rD. It made her grow up.3. How did being on a reality TV show change Speaker 3?A. It m ade him realize it’s important to be yourself.4. What did volunteering help Speaker 4 see?B. Genuine human kindness.2、Tony: Talking to us today in our Life Choices series is Joan Robinson, an academic counsellor at Manchester University. She gives advice to school students on choosing the right subject to study at university. Joan, welcome to the show. Joan: Thanks Tony.Tony: So Joan, what do our listeners need to think about when choosing a course? It’s a huge, potentially life-changing decision, isn’t it?Joan: Yes. I generally give students advice in two areas. Firstly, know yourself, and secondly, think to the future.Tony:When you say “know yourself” what do you mean?Joan: Basically, I mean evaluate your own personal strengths and weaknesses, your personality traits and the things you like.Tony: I see ... So how can our listeners do this?Joan:Well, start by asking yourself questions to help reflect on your life so far. For example, what subjects are you good at? Are you an organized and self-disciplined person? Are you confident and outgoing? Do you like working with others in a team or do you prefer working alone? These kinds of questions will help you discover more about yourself.Tony: Sounds like good advice. How about your second point regarding the future?Joan: Well, your choice of major subject is likely to have a significant impact on your future career so it’s important to look into this carefully. I recommend you check not only which academic subjects will help you get into a particular area of work, but also look carefully at what universities offer. Each university has its strengths so try to choose one that is the best in your chosen field. Find out what links the department has to related industries and leading companies in it.Tony: Good point. Now I’d like to take some calls from our listeners. First up we have James on the line. Hi James! How can we help?James: Hi. I’m interested in a career in IT and I’d like to ask Joan whether she thinks it’s better to go to a highly respected university, like Oxford, or to study somewhere that has more of a vocational focus? Joan: Well, James, you know it really depends on what you expect to get out of a university and how you see your future. Basically a handful of the brightest graduates are picked from the top universities around the world to join the leading IT companies. So I’d say if you’re a high-flyer then this is the route that might be for you. But if you are looking for a more mainstream career then you should consider a course that helps you acquire practical, transferable skills that you can use in the workplace ... and lookat which universities have the best levels of graduate recruitment for the kind of job you are aiming for. James: I see! Thanks a lot. That really helps me out …UNIT2Outside view1、Presenter: Around the world many children are living in poverty. Many children live in countries where there is war. Many children do not get enough to eat. Some of these children are suffering from malnutrition. Many children in the world cannot go to school. One agency that is helping these children is UNICEF. UNICEF means the United Nations Children’s Fund. UNICEF has more than 7,000 people working in 157 countries around the world to help children. One country where they are doing a great deal of work is Afghanistan. A whole generation of children in Afghanistan has never known peace, until recently. Now, UNICEF is bringing food for malnourished children. They are bringing medicine. Here a medical team travels on horseback to bring medicine to a remote mountain village. And UNICEF is helping the children get an education. DrLaroche: During the time of Taliban we have made a survey among 40,000 kids. And, uh, and they all say that the first thing they want is peace. And the second thing that they want is, was education. Presenter: The Taliban destroyed almost 2,000 schools. Under the Taliban, girls were not allowed to attend school at all.Moyeen: Well, over 50 per cent of the school has been destroyed completely. In the rest of the 50 per cent schools which, eh, eh, needs repair, we are trying to accommodate all the children in the schools. Presenter:Some of the schools are in people’s homes. This is a home school in Kabul. The teacher, HabibaKilwati, has been running the school for 12 years. She supervises 26 other schools like it.2、Student 1: We want to learn, so we can become teachers, doctors, or engineers and be like normal students.Presenter: It was dangerous for children to go to school.

For many adults, childhood memories revolve around the toys that they played with when they were younger. Seeing or holding an old toy from their past can transport them back to the time when they first laid eyes on it at the toy store, and the excitement they felt about taking it home to play. Toys from thepast were much simpler compared to the high-tech toys of today. Some may even argue that toys from the past encouraged children to use their creativity and imagination. In order to recapture their happy childhood memories, people collect old toys they had as children.There are many serious collectors who are willing to pay top prices to bring back memories. For example, Cabbage Patch Kids were dolls that were very popular in the 1980s. While toy stores still sell them, collectors want the original dolls and the rare collectibles are listed on eBay for up to $2,500. Other popular collectible toys are action figures such as G. I. Joes, Star Wars figures, My Little Ponies, and Barbie dolls.Q1: What is the difference between toys from the past and toys of today?D. Toys from the past encouraged more creativity and imagination than toys of today.Q2: What do we learn about old toys from the news report?B. Old toys can bring back happy memories for many people.Insideview1、One of the strangest feelings I’ve ever had was when I returned by chance to a place where I’d been happy as a child. My husband and I were visiting some friends for the weekend – they lived about 200 kilometres away. We were driving along when I suddenly saw a church in the distance that I recognized. My favourite aunt had lived very near it on a farm that my brother and I used to visit once a year with our parents.We were city kids, brought up in the middle of London, and this was a working farm – the real thing – with cows in cowsheds, fields with ponds and a muddy yard full of smelly pigs, and – we had the run of the whole place – it was just paradise for us. And then – there was the food – oh, home-made jam and bread and cakes, milk fresh from the cow. And my aunt Lottie –a farmer’s wife – and her husband, Uncle George and their kids, Katie and Ben, our two cousins who my brother and I really got on with. It was heaven that week we used to spend there. They moved from the farm when I was … how old? –about 14. So I’d never been back or seen it again.An yway, there we were, and I’d just seen the church –so we turned off and drove down this really narrow lane. And before I knew it we were in front of Aunt Lottie’s farm! The extraordinary thing was that it hadn’t changed – not one tiny bit.It was a lovely old place with a typical country cottage garden, full of flowers. There were lots of barns and sheds – they were next to –next to the farm. And you know, I can’t even begin to describe the feeling I had standing there. It was –oh, what was it? –an incredibly powerful feeling of longing –nostalgia for the past –for times when I’d been very, very happy. But it was the past. I hadn’t been there for 20 years and I couldn’t go back, so I also had a feeling of huge sadness, that I couldn’t havethose times again. And – at the same time – great sweetness, because those times had been so happy, so innocent –because I was a child! So there was this extraordinary mix –of longing, sadness and sweetness, all at the same time. It was the strangest feeling I’ve ev er had.1. Why were the speaker and her husband near the farm?C. Because they were visiting friends.2. Where had the speaker been brought up?B. In the middle of London.3. Why does the speaker describe the farm as “just paradise”?A. Because it was a real farm and she and her brother could run around.4. What food does the speaker mention?C. Jam, bread, cakes and milk.5. What do we learn about the farm?D. The garden was full of flowers.6. What feelings does the speaker mention?A. A longing for the past, sadness and sweetness.2、Interviewer:So what’s your first memory of school, Kevin?Kevin:I was really looking forward to school, I remember that, I just couldn’t wait. Yeah, Johnny, my brother, was a year older than me and he seemed so grown-up, with his red blazer and smart shoes.And I wanted to go to school and be grown-up too. I don’t remember much of the first day actually, apart from this little boy lying on the floor and screaming and screaming and me thinking what a baby he was. Interviewer: Right! What about you, Eva?Eva: I just have this one memory of this coat rack with all our coats. And I was looking for my peg which had a little picture of an elephant next to it. I remember I was crying because I wanted to go home and I coul dn’t get my coat on. I was crying so much and then the teacher came and helped me. Interviewer: OK, so what about your first best friend at school?Kevin:Oh, yeah, well, Steve, I remember him? because he’s still my best friend!Interviewer: Still your best friend!Eva:That’s so great!Kevin:Yeah, we didn’t know each other before we started school but we became really good friends and so did our mums. Our families ended up going on holiday together and that kind of thing. But we used to fight a lot, Steve and I, and the teachers used to get very cross with us. But we were just having fun. Interviewer: Cool! And what about you, Eva?Eva: My best friend was a girl called Robina. She had short blond hair, I remember I thought she looks (looked) like an angel. We sat next to each other and held hands and played fairies in the playground. She left in Year 3 and I cried for days. Interviewer: Oh, how sad! So what about the day you left school? How was that?Eva: I had a lot of mixed feelings, I remember walking home with this amazing feeling of freedom, you know, no more rules, no more bossy teachers. But I also felt pretty sad, because I’d had some good times. I was in a group of girls who were so supportive of each other.Kevin:I couldn’t wait to leave, I was counting the days. I just wanted to get a job, get a life, earn some cash. The day I left, I went out to celebrate with a couple of my mates and – had a very good time!UNIT3Outside view1、Part 1Voice-over: The Mona Lisa, the most famous painting in the world, was truly revolutionary even in its time. While he was painting the Mona Lisa, Leonardo da Vinci broke all the rules, even his own. In spite of the fact that Leonardo and other artists believed that women should only be portrayed with eyes gazing slightly down, Leonardo painted the Mona Lisa looking directly at the viewer. The position of her body is another innovation. While her face looks straight ahead her body is slightly turned, a pose that creates a sense of movement and tension. In another break from tradition, the Mona Lisa is not wearing any jewellery or adornments. Finally, backgrounds in portraits usually indicated a real place but the landscape in Leonardo’s portrait seems almost i maginary.Anne: One of the things I like to do is, um, think about her face and why, what is she trying, why, what is she trying to say with her face, and I used to think that her face told more than one story. For instance, if I covered up one side of her face, it seemed like she might be a little sad or reserved, almost secretive. Scott:Her eyes are, they’re kind of looking at us or around us, through us perhaps. I think with that painting she’s the viewer and we’re the subject in a way. And she has this look that she knows something that we don’t know.Anne: And then when I covered up that side and looked at the other side, she seemed happier, um, more satisfied. And together it created sort of the mystery about her that, um, made interpreting her face very enigmatic.Scott:There’s speculation that the Mona Lisa is a self-portrait of Leonardo and I, I believe that it is, there, there, the features do line up between the Mona Lisa and sketches of Leonardo.Voice-over:2、Part 2Anne: When I was young, um, I was always interested in, um, reading books about people and, and the dynamics, different kinds of relationships they had and so when I became a painter it was natural for me to be interested in painting people and looking for similar kinds of stories to tell about them, that you might read about in a book.Scott: Uh, most of my work consists of photographic self-portraiture. Um, I’m interested in using myself as the subject, um, not only as the creator of the image but as the, the character, or the performer of, of the images.Anne:So in my portraits I’m trying to capture, um, a deeper essence of a person, um, more or less. Scott: This work here is done with a pinhole camera, which requires a very long exposure so, with a portrait you can get this feelin g of time passed. It’s not a, it’s not an instant, per se, it could be five minutes of exposure.Anne:So this is another project I’m working on. I’m almost finished with it but I still need to work on the reflections in the water, um, and the face of the boy before it’s finished.Scott: I often work with multiples and, you know, using a mirror or the same image twice and what I wanted to do was link the two portraits together with the string. It’s kind of the string of thought or this idea of remembering or the resilience of memory.Anne:I don’t just paint from photographs. I try to make a work of art. Um, I try to make a painting that goes beyond a mere photographic image. I try to capture something about the soul of the, or the essence of this person.Scott:This piece here is, uh, it’s called The Measure of Decay and behind the piece there are portraits, again, of me. I have this clay covering on that has cracked and so it’s, it’s kind of like the process of decay. So as each portrait goes around you can, you can see the image in a different focus.Anne:I love painting portraits. I love painting but portraits are very special because they’re about people. Scott:I’m fascinated by portraiture in general, and the human body and how that image lives over ti me. Anne: I like to capture what is unique and special about an individual in paint.News report>1Israeli artist EyalGever is working on a project that will be the first artwork created in space. It will be a 3D sculpture made inside the International Space Station. He will create his artwork using a zero-gravity 3D printer. Once it is finished, the sculpture will be released into the universe.Working with NASA, Gever’s space project is named “Laugh”. The 3D printer will produce a physical representatio n of a person’s laugh. Sound cannot travel in space, but this sculpture can show what laughter looks like.Gever is asking people around the world to participate in his project. There is a social media campaign called “LaughInSpace”, where people are invit ed to record and submit their laughter online. When the audio samples have been collected, people will be invited to vote on which clip should be represented in the sculpture. Then Gever will use the sounds of the winner’s laughter to create the space scul pture.。

根3是无理数的证明

根3是无理数的证明今天咱们来一起看看为什么根3是无理数呢?这就像一场有趣的数学冒险哦。
咱们先来说说什么是有理数。
有理数呀,就像是我们能很容易找到规律的数。
比如说,1呀,2呀,还有像1/2这样的分数。
你看,1就是1个,2就是2个,1/2呢,就是把1个东西平均分成2份,每份就是1/2,这些数我们都能很清楚地知道它们是多少。
那无理数呢?无理数就像是一群调皮的小怪兽,藏在数字的世界里。
根3就是其中一个。
咱们来假设根3是有理数。
那按照有理数的定义,它就可以写成一个分数的样子,就像a/b(这里的a和b都是整数,而且b不能是0哦)。
而且呢,我们可以让这个分数是最简分数,就是说a和b没有除了1以外的共同的约数,就像3/4这样,3和4除了1就没有别的数能同时整除它们了。
那如果根3 = a/b,那把两边都平方一下,就得到3 = a²/b²,然后再变一变,就成了a² = 3b²。
这时候,咱们来想个例子哦。
假如a是个整数,那a²就是a乘以a。
比如说a = 5的时候,a² = 5×5 = 25。
那a² = 3b²这个式子呢,就说明a²是3的倍数。
那什么样的整数的平方是3的倍数呢?咱们可以试试一些数。
像1的平方是1,不是3的倍数;2的平方是4,也不是3的倍数;3的平方是9,这就是3的倍数啦。
其实呀,只有a本身是3的倍数的时候,a²才会是3的倍数。
那咱们就可以说a = 3k(k也是个整数)。
把a = 3k代入到a² = 3b²里,就变成了(3k)² = 3b²,算一算就是9k² = 3b²,再变一变就是b² = 3k²。
这就和前面说a²的情况一样啦,这就说明b也是3的倍数。
可是呢,我们最开始说a/b是最简分数呀,现在a和b都是3的倍数,这就矛盾啦,就像我们说好了一件事,结果发现这件事根本做不到一样。

内墙面砖施工方案
一、施工准备
1.材料
(1)水泥:普通硅酸盐32.5R水泥。
(2)砂子:中砂,用前过5mm筛孔筛子。
(4)面砖:面砖规格为厨房间200X300mm,卫生间250X330 mm,表面应光洁、方正、平整,质地坚硬,品种、规格、尺寸、色泽、图案符合设计和规范质量标准的要求。
2.机具设备
砂浆搅拌机、瓷砖切割机、筛子、手推车、小灰桶、铁锨、木抹子、铁抹子、铝合金靠尺、灰槽、小扫把、小灰铲、卷尺、铅丝、铅笔等。
3.作业条件
(7)墙柱面暗装管线、电线盒及门窗框安装完毕,并经检验合格。
(8)墙柱面必须坚实、清洁(无油污、浮浆、残灰等),影响面砖铺贴凸出墙柱面部分应凿平,过于凹陷墙柱面应用1:3水泥砂浆分层抹压找平。
(先浇水湿润后再抹灰)
(9)安装好的门窗框与墙柱间缝隙用1:3水泥砂浆堵灌密实;铝合金门窗框边缝隙嵌塞材料应由设计确定,铺贴面砖前应先粘贴好保护膜。
(10)大面积施工前应先做样板墙和样板间,并经质量有关部门检查符合要求。
(11)统一弹墙面上+50cm水平线。
二、操作工艺:
1.工程做法:a、刷混凝土界面处理剂一道;
b、7厚1:3水泥砂浆(掺水泥重量3%的防水剂)打底扫毛;
c、7厚1:2.5水泥砂浆(掺水泥重量3%的防水剂)找平扫毛;
d、9厚1:0.1:2.5水泥石灰膏砂浆结合层;
e、5厚1:1水泥细砂浆粘贴5厚内墙釉面砖,稀白水泥浆擦缝。
2.选砖
面砖一般按1mm差距分类选出若干个规格,选好后根据墙柱面积,房间大小分批类计划用料。
选砖要求方正、平整,楞角完好,同一规格的面砖,力求颜色均匀。
3.基层处理和抹底子灰
1)对光滑表面基层,应先打毛,并用钢丝刷满刷一遍,再浇水湿润。
2)对表面很光滑的基层应进行“毛化处理”。
即将表面尘土、污垢清理干净(油污可用10%碱水清刷后,再用清水将碱液冲洗干净);浇水湿润,用1:1水泥细砂浆掺加水重10%的108胶,用扫帚甩到光滑基层上。
甩点要均匀,终凝后再浇水养护,直至水泥砂浆疙瘩有较高的强度,用手掰不动为止。
3)加气砼墙面基层:提前一天浇水湿透。
4)抹底子灰:吊垂直,找规矩,贴灰饼(打墩),冲筋。
吊垂直找规矩时应与墙面的窗台、阳角立边等部位面砖贴面排列方法对称性以及室内地砖块料铺贴方正综合考虑,力求整体完美。
将基层浇水湿透,分层分遍用1:3水泥砂浆底灰,第一层为7mm厚,用铁抹子(铁灰匙)均匀抹灰密实;待第一层干至七~八成后即可抹第二层,厚度约为7mm,直至与冲筋大致相平,用木杠(压尺)刮平,再用木抹子(磨板)搓毛压实。
4.预排砖块、弹线
预排砖块应按照设计色样要求,一个房间,一整幅墙柱面贴同一分类规格面砖;在同一墙面,非整块面砖不得小于半砖,非整块面砖应排在靠近地面或不显眼的阴
角等位置;砖块排列一般自阳角开始,至阴角收口和自顶棚开始至楼地面收口。
弹好垂直与水平控制线,垂直控制线一般以1m为宜。
5.贴面砖
1)预先将釉面砖泡水浸透凉干(一般宜隔天泡水凉干备用)。
2)在每分段或分块内的面砖,均应自下一排的下皮位置用钉子装好靠尺板(室内靠尺板在地面向上第一排整砖的下皮位置上)以此承托第一排面砖。
3)用水将底子灰面湿润,先贴好第一排(最下一排)砖块下皮要紧靠装好的靠尺板砖面要求垂直平整,并应用木杠(压尺)校平砖面及砖上皮。
4)以第一排贴好的砖面为基准,贴上基准点(可使碎块面砖),并用垂线校正,以控制砖面出墙面尺寸和垂直度。
5)铺贴应从最低一皮开始,并按基准点挂线,逐排由下向上铺贴。
面砖背面应满涂水泥膏(厚度一般控制在2~3mm内,掺加水重10%的108胶)贴上墙面后用铁抹子木把手着力敲击,使面砖粘牢,同时用木杠(压尺)校平砖面及上皮。
每铺完一排应重新检查每块面砖,发现空鼓,应及时掀起加浆重新贴好。
6)铺贴完毕,待粘贴水泥砂浆初凝后,用清水将砖面洗干净,用白水泥浆将缝填平,完工后用棉纱、布片将表面试擦干净至不留残灰迹为止。
三、质量标准
1.主控项目
1)材料品种、规格、颜色、图案必须符合设计要求,质量应符合现行有关标准规定。
2)镶贴必须牢固,无空鼓无歪斜、缺楞、掉角和裂缝等缺陷。
2.一般项目
1)表面:观察检查和用小锤轻击检查。
平整、洁净、色泽一致,无起碱、污痕
和显著的光泽受损处。
无空鼓现象。
2)接缝:观察检查。
填嵌密实、平直、宽窄一致;颜色一致,阴阳角处的板压向正确,非整砖使用部位适宜。
3)套割:观察或尺量检查。
用整砖套割吻合、边缘整齐;墙裙、贴脸等上口平顺、突出墙面的厚度一致。
4)坡向、滴水线、观察检查。
流水坡向正确、滴水线顺直。
四、施工注意事项
避免工程质量通病
1)空鼓:基层清理不够干净;抹底子灰,基层没有保持湿润,面砖铺贴前没有事先泡浸或底子灰面没有保持湿润;面砖背抹水泥不够均匀或量不足;砂浆配合比不准,稠度控制不好,砂浆中含砂量过大,以及粘贴砂浆不饱满,面砖勾缝不严均可引起空鼓。
2)墙面脏:主要因为铺贴完成后,没有及时将墙面清洗干净,贴砖用水泥膏粘着砖面,以及擦缝时没有将多余白水泥浆彻底清干净。
此时可用棉纱稀盐酸加20%
水刷洗,然后用清水冲洗干净即可。
五、产品保护
1)门窗框上粘着的砂浆要及时清理干净。
2)拆架子时不要碰撞墙柱面的粉刷饰面。
3)对污染的墙柱面要及时清理干净。
4)搭铺平桥板严禁直接压在门窗框上,应在窗台适当位置垫放木枋(板),将平桥架离门窗框。
5)搬运料具时要注意不要碰撞以完成的设备、管线、埋件、门窗框及已完成粉刷饰面的墙柱面。
六、安全
1)进入工地必须戴安全帽。
2)使用脚手架时应先检查是否牢靠。
护身拦、挡脚板、平桥板是否齐全可靠,发现问题应及时修正好,才能在上面操作;脚手架上放置料具要注意分散并放平稳,不许超过规定核载,严禁随意向下抛掷杂物。
3)使用手提电动机,应接好地线及防漏电保护开关,使用前应先试运转,检查合格后,才能操作。
4)在黑暗处作业及夜班施工时,应使用36v低压灯照明。
5)使用钢井架做垂直运输时,应联系好上落信号,吊笼平层稳定后才能进行装卸作业。
