2mgo2点燃2mgo文字表达式

2mgo2点燃2mgo文字表达式

2mgo2点燃2mgo文字表达式2Mg + O₂点燃 2MgO,这看起来就是几个字母和数字的组合,可这里头藏着的是一个奇妙的化学世界呢。

你看啊,镁(Mg)就像是一个充满活力的小战士,氧气(O₂)呢,就像是无处不在的精灵。

当镁这个小战士遇到氧气精灵的时候,那可就不得了啦。

就好比一个热血青年在充满奇幻色彩的仙境里,只要一点燃那团热情之火,就会发生神奇的变化。

这就跟我们人似的,有时候遇到对的环境或者对的契机,也会爆发出不一样的力量。

镁和氧气的反应啊,就像是一场盛大的舞会。

镁带着自己的热情,氧气带着自己的灵动,在火焰这个指挥棒下,开始了一场惊心动魄的共舞。

它们相互拥抱、融合,最后变成了氧化镁(MgO)。

这氧化镁啊,就像是它们爱情的结晶,见证了镁和氧气之间独特的结合过程。

我还记得我第一次看到镁条在氧气中燃烧的时候,那场面,真叫一个震撼。

镁条就像一根小魔杖,在氧气的包围下,发出耀眼的白光,那白光刺得眼睛都有点睁不开。

这就像黑暗中突然出现了一颗超级明亮的星星,把周围的一切都照亮了。

那时候我就在想,这小小的化学物质,怎么能产生这么大的能量呢?就像有时候我们小看了身边的某个人,结果人家一发挥,那能力简直超乎想象。

从这个化学表达式里,我们还能看出一些别的门道。

你想啊,原本是镁和氧气这两种不同的东西,经过反应就变成了一种新的物质。

这多像我们的生活啊,不同的人和不同的事物相互作用,最后产生新的变化。

比如说不同的文化相互交融,就会产生新的文化特色。

就像把中国的传统文化和西方的现代文化放在一起,相互影响,就出现了很多既有中国韵味又有西方时尚感的新事物。

再说说这反应的条件——点燃。

这就像是一个启动键,没有这个点燃的动作,镁和氧气可能就一直相安无事地各自存在着。

这就好比我们有时候也需要一个触发点,才能激发自己的潜力。

就像一个平时很内向的人,可能参加了一场演讲比赛,就像是被点燃了一样,突然变得自信大方起来。

这个化学表达式,不仅仅是化学课本上的知识,它更像是生活的一个小小缩影。

周边地面 2

周边地面 2

周边地面——对没有地下室的建筑指底层房间外墙内侧两米范围内的地面。

对有地下室埋墙的建筑,指从室外地面和埋墙的交线算起向下两米内为周边地面。

非周边地面——对没有地下室的房间指底层地面中周边地面以外的部分。

有地下室埋墙的建筑,非周边地面指埋墙和地面面积的和减去从室外地面和埋墙交线算起向下两米的面积。

关于周边地面和非周边地面的几点说明1.周边地面和非周边地面的定义周边地面指距外墙内表面2m以内的地面,其余部分划为非周边地面。

位于室外地面以下的外墙(地下室外墙)应从与室外地面相平的墙壁算起,往下2m范围内为周边地面,其余部分划为非周边地面。

2.节能标准中对周边地面和非周边地面传热阻的计算《民用建筑节能设计标准》(采暖居住部分)JGJ26-95和《公共建筑节能设计标准》GB50189-2005对周边地面和非周边地面热阻采用了不同的计算方法,应分别对待。

A) 居住建筑:换热阻计算依据来源于《供热工程》(贺平孙刚编著)。

由于室内热量通过地面传到室外的路程长短不同,即热阻值不同,靠近外墙的室内地面,距离室外路程短,热阻值小,传热量大,反之远离外墙的地面热阻值大,传热量小,离外墙8m以远的地面,传热量基本不变。

基于上述情况,在工程上一般采用近似方法计算,把地面沿外墙平行的方向分成四个计算地带(每2m为一个地带,8m以外地面按第四地带考虑),如图1示。

1) 对于贴土非保温地面(组成地面的各层材料导热系数λ都大于1.16W/m?℃),各地带的传热系数和换热阻如下:周边地面传热系数限值为0.52 W / m2·℃地区,考虑到非保温地面第一地带(周边地面)的传热系数为0.47 W / m2·℃,小于限值0.5 2W / m2·℃,可不做保温;非周边地面(第二、三、四地带)不做保温时传热系数最大值为0.23 W / m2·℃,小于限值0.3 W / m2·℃,同样也能满足非周边地面限值的要求。

Meanwhile,the asocial robot simply moved forwards and backwards and side to side Next,the researchers tapped the robots in cages and gave the rats the opportunity to release them by pressing a lever.Across18trials each,the living rats were52percent more likely on average to set the social robot free than the asocial one.This suggests that the rats perceived the social robot as a genuine social being.They may have bonded more with the social robot because it displayed behaviours like communal exploring and playing. This could lead to the rats better remembering having freed it earlier,and wanting the robot to return the favour when they get trapped,says Quinn.The readiness of the rats to befriend the social robot was surprising given its minimal design.The robot was the same size as a regular rat but resembled a simple plastic box on wheels.“We’d assumed we’d have to give it a moving head and tail, facial features,and put a scene on it to make it smell like a real rat,but that wasn’t necessary,”says Janet Wiles at the University of Queensland in Australia,who helped with the research.The finding shows how sensitive rats are to social cues,even when they come from basic robots.Similarly,children tend to treat robots as if they are fellow beings, even when they displayonly simple social signals.”We humans seem to be fascinated by robots,and it turns out other animals are too,”says Wiles.21.Quinn and her colleagues conducted a test to see if rats can[A]pickup social signals from non-living rats[B]distinguish a friendly rat from a hostile one[q attain sociable traits through special training[D]send out warming messages to their fellow22.What did the social robot do during the experiment?[A]It followed the social robot.[B]It played with some toys.[C]It set the trapped Tats free.[D]It moved around alone.23.According to Quinn,the rats released the social robot because they[A]tried to practice a means of escape[B]expected it to do the same in return[C]wanted to display their intelligence[D]considered that an interesting game24.James Wiles notes that rats______[A]can remember other rat’s facial features[B]differentiate smells better than sizes[C]respond more to cations than to looks[D]can be scared by a plastic box on wheels25.It can be learned from the text that rats______[A]appear to be adaptable to new surroundings(B]are more socially active than other animals[C]behave differently from children in socializing[D]are more sensitive to social cues than expectedText2It is fashionable today to bash Big Business.And there is one issue on which the many critics agree:CEO pay.We hear that CEOs are paid too much(or too much relative to workers),or that they rig others’pay,or that their pay is insufficiently related to positive outcomes.But the more likely truth is CEO pay is largely caused by intense competition.It is true that CEO pay has gone up—top ones may make300times the pay of typical workers on average,and since the mid-l970s,CEO pay for large publicly traded American corporations has,by varying estimates,gone up by about500%The typical CEO of a top American corporation—from the350largest such companies—now makes about$18.9million a year.While individual cases of overpayment definitely exist,in general,the determinants of CEO pay are not so mysterious and not so mired in corruption.Infact,overall CEO compensation for the top companies rises pretty much.In lockstep with the value of those companies on the stock market.The best model for understanding the growth of CEO pay,though,is that of limited CEOtalent in a world where business opportunities for the top firms are growing rapidly. The efforts ofArnerica’s highest-earning l%have been one of the more dynamic elements of the global economy.It’s not popular to say,but one reason their pay has gone up so much is that CEOs really have upped their game relative to many other workers in the U.S.economy.Today’s CEO,at least for major American firms,must have many more skills than simply being able to“run the company.”CEOs must have a good sense of financial markets and maybe even how the company should trade in them.They also need better public relations skills than their predecessors,as the costs of even a minor slipup can be significant.Then there’s the fact that large American companies are much more globalized than ever before,with supply chains spread across a larger number of countries.To lead in that s stem requires knowledge that is fairlymind-boggling.There is yet another trend:virtually all major American companies are becoming tech companies,one way or another.An agribusiness company for instance,may focus on R&D in highly IT-intensive areas such as genome sequencing.Similarly;it is hard to do a good job running the Walt Disney Company just by picking good movie scripts and courting stars;you also need to build a firm capable of creating significant CGI products for animated movies at the highest levels of technical sophistication and with many frontier innovations along the way.On top of all of this,major CEOs still have to do the job they have always done—which includes motivating employees,serving as an internal role model, helping to define and extend a corporate culture,understanding the internal accounting,and presenting budgets and business plans to the board.Good CEOs are some of the world’s most potent creators and have some of the very deepest skills of understanding.26.which of the following has contributed to CEO pay rise?A.The growth in the number of cooperationsB.The general pay rise with a better economyC.Increased business opportunities for top firmsD.Close cooperation among leading economicspared with their predecessors,today’s CEOs are required to_.A.foster a stronger sense of teamworkB.finance more research and developmentC.establish closer ties with tech companiesD.operate more globalized companies28.CEO pay has been rising since the1970s despite.A.continual internal oppositionB.strict corporate governanceC.conservative business strategiesD.repeated governance warnings29.High CEO pay can be justified by the fact that it helps.A.confirm the status of CEOsB.motive inside candidatesC.boost the efficiency of CEOsD.increase corporate value30.The most suitable title for this text would be.A.CEOs Are Not OverpaidB.CEO Pay:Past and PresentC.CEOs’Challenges of TodayD.CEO Traits:Not Easy to DefineText3Madrid was hailed as a public health beacon last November when it rolled out ambitious restrictions on the most polluting cars.Seven months and one election day later,a new conservative city council suspended enforcement of the clean air zone,a first step toward its possible demise.Mayor Jose Luis Martinez-Almeida made opposition to the zone a centrepiece of his election campaign,despite its success in improving air quality.A judge has now overruled the city’s decision to stop levying fines,ordering them reinstated.But with legal baffles ahead,the zone’s future looks uncertain at best.Among other weaknesses,the measures cities must employ when left to tackle dirty air on their own are politically contentious,and therefore vulnerable.That’s because they inevitably put the costs of cleaning the air on to individual drivers—who must pay fees or buy better vehicles—rather than on to the car manufacturers whose cheating is the real cause of our toxic pollution.It’s not hard to imagine a similar reversal happening in London.The newultra-low emission zone(Ulez)is likely to be a big issue in next year’s mayoral election.And if Sadiq Khan wins and extends it to the North and South Circular roads in2021as he intends,it is sure to spark intense opposition from the far larger number of motorists who will then be affected.It’s not that measures such as London’s Ulez are useless.Far from it.Local officials are using the levers that are available to them to safeguard residents’health in the face of a serious threat.The zones do deliver some improvements to air quality,and the science tells us that means real health benefits-fewer heart attacks, stokes and premature births,less cancer,dementia and asthma.Fewer untimely deaths.But mayors and councilors can only do so much about a problem that is far bigger than any one city or town.They are acting because national governments—Britain’s and others across Europe—have failed to do so.Restrictions that keep highly polluting cars out of certain areas—city centres,”school streets”,even individual roads-are a response to the absence of alarger effort to properly enforce existing regulations and require auto companies to bring their vehicles into compliance-Wales has introduced special low speed limits to minimise pollution.We re doing everything but insist that manufacturers clean up their cars.31.Which of the following is true about Madrid’s clean air zone?[A]Its effects are questionable[B]It has been opposed by a judge[C]It needs tougher enforcement[D]Its fate is yet to be decided32.Which is considered a weakness of the city-level measures to tackle dirty air?[A]They are biased against car manufacturers.[B]They prove impractical for city councils.[C]They are deemed too mild for politicians.[D]They put too much burden on individual motorists.33.The author believes that the extension of London’s Ulez will.[A]arouse strong resistance.[B]ensure Khan’s electoral success.[C]improve the city’s traffic.[D]discourage car manufacturing.34.Who does the author think should have addressed the problem?[A]Local residents[B]Mayors.[C]Councilors.[D]National governments.35.It can be inferred from the last paragraph that auto companies-[A]will raise low-emission car production[B]should be forced to follow regulations[C]will upgrade the design of their vehicles[D]should be put under public supervisionText4Now that members of Generation Z are graduating college this spring—the mostcommonly-accepted definition says this generation was born after1995,give or take a year—the attention has been rising steadily in recent weeks.GenZs are about to hit the streets looking for work in a labor market that’s tighter than its been in decades.And employers are planning on hiring about17percent more new graduates for jobs in the U.S.this year than last,according to a survey conducted by the National Association of Colleges and Employers.Everybody wants to know how the people who will soon inhabit those empty office cubicles will differ from those who came before them.If“entitled”is the most common adjective,fairly or not,applied to milennials (those born between1981and1995),the catchwords for Generation Z are practicaland cautious.According to the career counselors and experts who study them, Generation Zs are clear-eyed,economic pragmatists.Despite graduating into the best economy in the past50years,Gen Zs know what an economic train wreck looks like.They were impressionable kids during the crash of2008,when many of their parents lost their jobs or their life savings or bo&They aren’t interested in taking any chances.The booming economy seems to have done little to assuage this underlying generational sense of anxious urgency,especially for those who have college debt-College loan balances in the U.S.now stand at a record$1.5trillion,according to the Federal Reserve.One survey from Accenture found that88percent of graduating seniors this year chose their major with ajob in mind.In a2019survey of University of Georgia students,meanwhile,the career office found the most desirable trait in a future employer was the ability to offer secure employment(followed by professional development and training,and then inspiring purpose)Job security or stability was the second most important career goal(work-life balance was number one), followed by a sense of being dedicated to a

all get along perfectly.But unlike in friendships,you need coworkers.You work with them every day and you depend on them just as they depend on you.Here are some ways that you can get the whole office on your side.41.If you have a bone to pick with someone in your workplace,you may try stay tight-lipped around them.But you won’t be helping either one of you.A Harvard Business School study found that observers consistently rated those who were frank about themselves more highly while those who hid lost trustworthiness.The lesson is not that you should make your personal life an open book,but rather,when given the option to offer up details about yourself or painstakingly conceal them,you should just be honest42.Just as important as being honest about yourself is being receptive to others. We often feel the need to tell others how we feel,whether it’s a concern about a project,a stray thought,or a compliment.Those are all valid,but you need to take time to hear out your coworkers,too.In fact,rushing to get your own ideas out there can cause colleagues to feel you don’t value their opinions.Do your best to engage coworkers in a genuine,back-and-forth conversation,rather than prioritizing your own thoughts.43.It’s common to have a“cubicle mate”or special confidant in a work setting.But in addition to those trusted coworkers,you should expand your horizons and find out about all the people around e your lunch and coffee breaks to meet up with colleagues you don’t always see.Find out about their lives and interests beyond the job.It requires minimal effort and goes a long way.This will help to grow your internal network,in addition to being a nice break in the work day.44-Positive feedback is important for anyone to hear.And you don’t have to be someone’s boss to tell them they did an exceptional job on a particular project.This will help engender good will in others.But don’t overdo it or be fake about it One study found that people responded best to comments that shifted from negative to positive,possibly because it suggested they had won somebody over.45.This one may be a bit more difficult to pull off but it can go a long way to achieving results.Remember in dealing with any coworker what they appreciate from an interaction.Watch out for how they verbalize with others.Some people like small talk in a meeting before digging into important matters,while other are more straightforward.Jokes that work one person won’t necessarily land with another.So, adapt your style accordingly to type.Consider the person that you’re dealing with in advance and what will get you to your desired outcome.Section III TranslationDirections:Translate the following text into Chinese.Write your translation neatly on the ANSWER SHEET.(15points)It’s almost impossible to go through life without experiencing some kind of failure.People who do so probably live so cautiously that they go nowhere.Put simply,they’re not really living at all.But,the wonderful thing about failure is that it’s entirely up to us to decide how to look at it.We can choose to see failure as“the end of the world,”or as proof of just how inadequate we are.Or,we can look at failure as the incredible learning experience that it often is.Every time we fail at something.we can choose to look for the lesson we’re meant to learn.These lessons are very important,they’re how we grow,and how we keep from making that same mistake again.Failures stop us only if we let them.Failure can also teach us things about ourselves that we would never have learned otherwise.For instance,failure can help you discover how strong a person you are.Failing at something can help you discover your truest friends,or help you find unexpected motivation to succeed.Section IV WritingPartA46.Directions:Suppose you are planning a tour of a historical site for a group of international students.Write an email to1)tell them about the site,and2)give them some tips for the tourPlease write your answer on the ANSWER SHEETDo nor use your own name,use“Li Ming”instead.(10points)Part B47.Directions:Write an essay based on the chart below.In your writing,you should1)interpret the chart,and2)give your commentsYou should write about150words on the ANSWER SHEET.(15points)2020年考研英语二答案解析Section I Use of English1.【答案】D tricky【解析】此处考察词义辨析+上下文语境。

That is a very short timeline, so we can onlyimagine what the changes will be further in the future.The question of who should pay for reskilling is a thorny one Forindividual companies, the temptation is always to let go of workerswhose skills are no longer demand and replace them with thosewhose skills are.That does not always happen.AT&T is often given asthe gold standard of a company who decided to do a massivereskilling program rather than go with a fire-and-hire strategy.ultimatelyretraining 18,000employees. Prepandemic,othercompanies including Amazon and Disney had also pledged to createtheir own plans. When the skills mismatch is in the broader economythough, the focus usually turns to government to handle. Efforts inCanada and elsewhere have been arguably languid at best, and havegiven us a situation where we frequently hear of employers beggingfor workers even at times and In regionswhere unemployment is high.With the pandemic, unemployment is veryhigh indeed. In February,at 3.5 per cent and 5.5 per cent respectively,unemployment rates inCanada and the United States were at generational lows and workershortages were everywhere.As of May, those rates had spiked up to13.3 per cent and 13.7 per cent, and although many worker shortageshad disappeared, not all had done so. In the medical field, to take anobvious example,the pandemic meant that there were still clearshortages of doctors, nurses and other medical personnelOf course, it is not like you can take an unemployed waiter andtrain him to be a doctor in a few weeks, no matter who pays for it.Buteven if you cannot close that gap, maybe you can close others, anddoing so would be to the benefit of all concerned That seems to bethe case in Sweden, where the pandemickick-started a retrainingprogram where business as well as government had a role.Reskiling in this way would be challenging in a North Americancontext. You can easily imagine a chorus of"you cant do that,"because teachers or nurses or whoever have special skills, and usingany support staff who has been quickly trained is bound to end indisaster. Maybe. Or maybe it is something that can work 'ell inSweden,with its history of co-operation between business,labourand government, but not in North Americawhere our history is verydifferent. Then again, maybe it is akin to wartime, when extraordinarythings take place, but it is business as usualafter the fact.And yet, asin war the pandemic is teaching us that many things, including rapidreskilling, can be done if there is a will to do them. In any case,Swedens work force is now more skilled, in more things,and moreflexible than it was before.Of course, reskilling programs, whether for pandemic needs or thepostpandemic world,are expensive and at a time when everyonesbudgets are lean this may not be the time to implement them.Thenagain,extending income support programs to get us through thenext months is expensive, too, to say nothing of the cost of having aswath of long-term unemployed in thePOST-COVID years Given that,perhaps we should think hard about whether the pandemic canjump-start us to a place where reskilling becomes much more than abuzzword.B.PreDaacancies for the unemplovo teau.e1C.

Microsoft' s ownOffice dominates the market for"productivity"software, but thestart-ups represented a new wave of technology designed from theground up for the smartphone world.Both apps, however, were later scrapped, after Microsoft said it hadused their best features in its own productsTheir teams of engineersstayed on, making them two of the many" acqui-hires"that thebiggest companies have used to feed their insatiable hunger for techtalent.To Microsoft’ s critics,the fates of Wunderlist and Sunrise areexamples of a remorseless drive by Big Tech to chew up anyinnovative companies that lie in their path. " They bought theseedlings and closed them down,"complained Paul Arnold, a partnerat San Francisco-based Switch Ventures, putting paid to businessesthat might one day turn into competitors. Microsoft declined tccomment.Like other start-up investors,Mr Arnold ' s own business oftendepends on selling start-ups to larger tech companies,though headmits to mixed feelings about the result:"I think these things aregood for me, if I put my selfish hat on. But are they good for theAmerican economy? I don' t know.”The US Federal Trade Commission says it wants to find the answerto that question. This week, it asked the five most valuable US techcompanies for information about their many smallacquisitions ovelthe past decade. Although only a research project at this stage, therequest has raised the prospect of regulators wading into early-stagetech markets that until now have been beyond their reach.Given their combined market value of more than $5.5tn,riflingthrough such small deals —many of them much less prominent thanwunderlist and Sunrise —might seem beside the point. Betweenthem,the five companies (Apple,Microsoft,Google,Amazon andFacebook) have spent an average of only $3.4bn a year on sub-$1bnacquisitions over the past five years a drop in the ocean compared with their massive financial reserves, and the more than$130bn of venture capital that was invested in the US last year.However, critics say that the big companies use such deals to buytheir most threatening potential competitcrs before their businesseshave a chance to gain momentum, in some cases as part of a"buyand kill" tactic to simply close them down31.

In one study of the ability she dubbed"thin slicing,"the late psychologist Nalini Ambady asked participants to watchsilent 10-second video clips of professors and to rate the instructor's overall effectiveness. Their ratings correlated strongly withstudents’ end-of-semester ratings.Another set of participants had tccount backward from 1,000 by nines as they watched the clips,occupying their conratings were just asaccurate, demonstrie social processing.Critically, anotherninute writing downreasons for their Jjudgment,betore giving the rating.

She found similar interference whenparticipants watched 15-second clips of pairs of people and judgedwhether they were strangers, friends, or dating partners.Other research shows we' re better at detecting deception andsexual orientation from thin slices when we rely on intuition insteadof reflection.“It' s as if you' re driving a stick shift," says Judith Hall,a psychologist at Northeastern University,"and if you start thinkingabout it too much, you can' t remember what you’ re doing.

中铁二十二局集团有限公司
大张高速铁路(河北段)DZSG2015-1标项目经理部
二零一六年三月
钢筋加工场标准化建设方案
一、工程概况:
路桥工区共有特大桥2座,大桥3座。

本项目共有钢筋约1.7万吨,通过生产能力及供应需求核算。

为便于集中化管理,在2#搅拌站内设置一座钢筋加工场。

二、钢筋加工场选址
1#钢筋加工场位于G110国道边2#搅拌站院内,主要负责跨京新高速特大桥、跨张呼右线特大桥、耙齿沟1#大桥、耙齿沟2#大桥、朱家窑大桥的桩基础、承台、墩身、连续梁钢筋的制作,总占地面积2400m2,其中长度为80m,宽度为30m,高度为13m-15m。

三、场房抗风雪检算
采用单层彩钢板,轻钢结构组成。

基础为配筋砼独立柱基,钢柱为325*6圆钢管和180*4圆钢管组合成三角弧型梁及梁,柱间采用电焊连接。

屋面为单层彩钢瓦,檩条构件与屋面板之间用自钻自攻钉固定,立柱间距5m。

其设计为荷载值:
(1)屋面:静荷载:0.15KN/m²
(2)屋面:活荷载:0.2KN/m²
(3)雪荷载:0.25KN/m²
(4)基本风压:0.55KN/m²
2、结构用钢,钢材强度设计值。

(1)抗压,抗拉和抗弯值:215N/mm²
(2)抗剪:125N/mm²
(3)拱起顶紧后承压:325N/mm²
3、焊缝连接强度设计值(焊接焊条均为E43型)
(1)对接焊缝抗压:215N/mm²
(2)对接焊缝抗拉:215N/mm²
(3)对接焊缝抗剪:125N/mm²
(4)角焊缝抗压,抗拉,抗剪:160N/mm²
4、普通螺栓(C级)连接强度设计值。

(1)抗拉,抗弯:170N/mm²
(2)抗剪:130N/mm²
5、强度设计值折减系数。

(1)单面连接钢管:0.85
(2)长边相连的钢管:0.25
屋面板核校:
(1)大棚屋面板均为0.4mm厚单层彩钢压型图,自重0.08KN/m²(2)单层彩钢压型板的值:I=194cm4。

I=4.9cm,w=38.8cm3,A=7.8cm2 (3)檀条屋面板设计值:屋面为0.5KN/m2
(4)核校其弯距值:活荷载*1.4+静荷载*1.2
由(3)得出层面板的线性荷载值为0.6KN/m
总值0.5KN/m2*1.2m*1.4+0.15KN/m2*1.2m*1.2≈1.05KN/m
P=ql/8
=1.05KN/m*(6.0m)/8
=4.73KN/m
∴q=p/w
=4.73KN/m/38.8cm3
=12.2KN/cm2
Θ(a)=21.5KN/cm2>a
Θ屋面板的弯距值符合设计值。

(2)屋面板挠度核校:
根据《钢结构设计规范》檩条挠度取值
V标=1/1200=3.3cm
根据公式V 标=(5*ql4)/(384EI)-ql4/(4EI)
=(5*0.78KN*(6.0m)4)/(384*2.06*107N/cm2*1944)
(0.78KN*(1.2m)4)/(4*2.06*10N/cm2*194cm4)
=3.19cm
ΘV标>V实
∴屋面板挠度设计值合理
屋面钢管弧度型梁的校核:
(1)根据规范计算得出屋面的荷载值
2.0KN/m2*1.4+0.75KN/m2*1.2=
3.7KN/m2
屋面弧型梁其斜缀条为18*2.5钢管焊接,其斜度在40。

~70。

的范围内,合乎规范。

∠=500mm.A=1.432
=5/384*27.5562kn/m*(3.6m)4/2.06*104kn/cm*5946.5cm4
=0.492cm
ΘV<V标
∴框架梁挠义设计值合理
四、承载力检算
混凝土标号:混凝土选用C20标号。

混凝土厚度25cm,C20轴心抗压是20.1Mpa=20.1N/mm2=20.1×1 000000N/m2,相当于20.1×100000千克(五个零,除以10,重力加速度),也就是20.1×100吨,即2010吨/m2,因为是25cm厚混凝土,所以需要乘以0.25,因此推算每立方米的25cm厚的C20混凝土的抗压能力约为502.5吨/m3。

根据上述可知,素混凝土路面的抗压承载力主要取决于混凝土厚度,因此需要根据已知厚度可以通过公式计算出极限承载力。

Fcd=0.7·βh·Ftd·Um·H
Fcd——混凝土最大集中返力;
βh——对于厚度小于300mm时,取1;
Ftd——轴心抗拉应力(C20取1.39mpa);
Um——高度换算比=2·(a+b)+4H,a=20cm,b=60cm(a,b分别为轮迹宽、长);
H ——厚度。

带入数值即对应关系:
C20混凝土 25cm 极限车辆承载力:63.245吨;2#拌合站材料运输车自重17.5吨、载重37.5吨-40吨,因此总计极限重量约57.5
吨,因此25cm厚度混凝土路面满足使用需求。

基础承载力根据混凝土极限承载力63.245吨可知,基础承载力不应小于632.5/4=158kpa.因此基础承载力在满足不小于158kpa时可满足使用需求。

五、硬件设施要求
1、加工场内部功能区划分包括加工制作区、原材料堆放区、半成品堆放区、废料堆放区、运输通道等。

2、本座钢筋加工场占地面积达到2400平方。

3、场区内原地面采用清砂填筑50cm,再填筑30cm碎石,整平后地面采用25cm厚C20混凝土整体硬化。

地面混凝土浇筑后切割5条横缝1条纵缝,地面按照中间高两边低的原则设置2%的横坡,并在两侧设置30cm深排水沟。

钢筋笼堆放区、钢筋笼加工区、原材料堆放区(详见1#钢筋场地布置图)。

4、场地硬化按东侧高,西侧低,面层设1.5%排水坡度,水流向场外排水沟,排水沟底面采用M7.5砂浆进行抹面,沟底C20砼浇筑。

5、采用30米跨度龙门吊配合钢筋加工制作。

并作相应标识,按型号、类别登记入册,以便查询。

8、成品、半成品堆放区:对于加工完成的半成品、成品钢筋,按其检验状态与结果、使用部位进行标识,分类存放。

成品、半成品存放区应通风良好,支垫采用30工字钢,焊接成支架支撑,离地30cm 以上,下部支点应以保证成品、半成品不变形为原则。

易于滑落的材料堆放必须捆绑牢固,高度不得超过2m,并做好防滑措施。

9、钢筋、型钢和管材等金属材料,必须具有产品合格证,按规定存放,并避免与酸、碱等腐蚀性介质接触。

10、钢筋加工场设置废料区,严禁厂内钢筋头等杂物随手丢弃,应防止在回收桶里,便于集中回收。

六、机械设备要求:
1、场内配备1台10吨龙门吊。

龙门吊由专业厂家生产,使用前必须获得有关部门的检查验收合格后才能投入使用,严禁使用自行组装的龙门吊。

2、钢筋加工场加工设备,以满足钢筋加工的精确度和减少人工消耗,1台钢筋切断机、2台钢筋弯曲机、1台钢筋笼滚焊机、一台钢筋调直机、一台闪光对焊机、4台电焊机。

以上机械配置为每天出10个钢筋笼做的配置。

(根据现场进度要求,及时进行调整机械投入量。


五、人员配置要求:
根据每天成笼10个来考虑人员配置18人,其中电焊工4人,钢筋调直机2人,弯曲机2人、对焊机3人、下料3人,绑扎箍筋2人、杂工2人。

六、安全、文明施工及标准化建设:
1、安全:
场区各个功能区必须在明显位置设置防火设施,每个功能区的灭火器的数量不少于2个(5kg),钢筋加工场要设置配备相应的沙箱等相应的灭火器材。

电焊产生的有害气体及时通过窗子排出,确保人身安全。

2、文明施工:
进入施工现场要戴好安全帽,穿好防护鞋,严禁穿凉鞋、拖鞋上班。

做好工完场清工作,加工完短小废料要及时清理合理回收充分利用。

3、标准化建设
本钢筋棚采用全封闭形式因此考虑采光、通风措施
1)采光:白天自然采光,在钢筋棚两个侧面共计有30个窗户,窗户尺寸为1m*2m。

在钢筋棚的顶部采用16块阳光板,窗子间距为5m,窗子尺寸为10m*0.9m。

2个推拉式门尺寸为10m*6m。

晚上采光用4个射灯分别安装在钢筋加工场四周。

2)通风:在钢筋棚南北两侧设置窗子,保障加工区内空气流通。

3)钢筋加工场场区内规划建设:(详见钢筋加工场平面布置图) 4)在钢筋场东侧设置员工休息区(详见钢筋加工场平面图);
1、钢筋加工场尺寸为80m*30m分为原材存放区区、钢筋加工区、半场品存放区、成品存放区、废料区等功能区。

2、钢筋加工场垫钢筋材料为30#b工字钢,竖向立柱采用18工字钢。
