扭剪型高强螺栓连接工艺标准2

1.2普通紧固件连接工程施工工艺

General Parts Construction Technology

（1）成品进场

Refined Approach

普通螺栓、铆钉、自攻螺钉、拉铆钉、射钉、锚钉（膨胀型和化学试剂型）、地脚锚栓等坚固标准件及螺母、垫圈等等标准配件，其品种、规格、性能等符合现行国家产品标准和设计要求。

Ordinary bolts, rivets, and self-drilling screws, rivets (expansion and chemical reagents), to such strong legs stud and nut standard parts, gaskets, etc. standard accessories, variety, specifications, and other products with existing national standards and design requirements.

（2）螺栓实物复验

Complex and bolts kind experience

普通螺栓作为永久性连接螺栓使用时，当设计有要求或对其质量有疑义时，应进行螺栓实物最小拉力载荷复验，其结果符合国家标准《坚固件机械性能、螺栓、螺钉和螺柱》（GB3098）的规定。

Ordinary bolt connecting bolts as a permanent use, when the design requirements or questions about its quality should be carried out when the smallest lag bolts kind complex load testing and the results were consistent with national standard《mechanical fasteners, bolts, screws and stud》(GB3098).

（3）匹配及间距

Matching and spacing

连接薄钢板采用的自攻螺钉、拉铆钉、射钉等其尺寸与被连接钢板相匹配，其间距、边距等应符合设计要求。

Thin plate connecting the self-drilling screws, rivets, such as its size and connecting plate by matching their distance, should comply with the design requirements and other fringe. （4）螺栓坚固

Solid bolts

永久性普通螺栓紧固应牢固、可靠，外露丝扣不应少于2扣。

Ordinary bolt should be firmly secured permanent, reliable, not less than two exposed screw deduction.

（5）外观质量

Appearance Quality

自攻钉、钢拉铆钉、射钉等与连接钢板应紧固密贴，外观排列整齐。

Since the attack nails, rivets Steel, Steel Nailing should be secured so closely connected with stickers topology neat appearance.

1.3.2螺栓长度的选择

Bolt length option

扭剪型高强螺栓的长度为螺栓头根部至螺栓梅花卡头切口处的长度.选用螺栓的长度应为紧固连接板厚度加上一个螺母和一个垫圈的厚度,并且紧固的要露出不少于两扣螺纹的余长,一般按连接板厚加表5-2中的增加长度,并取5㎜的整倍数.

Torsional shear length of the high-strength bolts bolt-head bolts Plum card to the root of the length of the first incision. The length should be chosen for the fastening bolts interconnects thickness with a thickness of the nut and a washer and fastening the show at least two of the detained more than a l0ng thread, the general increase in table 5-2 by thick interconnects increase in the length of 5 mm and take the whole multiples.

1.3.3接头组装

Joint assembly

连接处的钢板或型钢应平整,板边、孔边无毛刺；接头处有翘曲、变形必须进行校正，并防止损伤摩擦面，保证摩擦面紧贴。

The link should be formed steel plate, plate edge, no burr hole; A joint warping, used to be calibrated to prevent injury and friction, the friction surface to ensure close.

配件前检查摩擦机，试件的摩擦系数是否达到设计要求，浮锈用钢丝刷除掉，油污、油漆清除干净。

Before friction machine parts inspection, the friction coefficient whether the specimen design requirements, floating steel brush to remove rust, oil, paint cleanse.

板叠接触面间应平整，当接触有间隙时，应按规定处理，见表5-3

Stack contact area should be formed, when the contact gap, should be required to handle, as shown in table 5-3

表5-3

间隙大小Gap size 处理方法Approach

1㎜以下1 mm below 不作处理Not processing

3㎜以下3 mm below 将高出的侧磨成1：10斜面打磨方面应与受力方面垂直 1:10 inclined to the higher side of the flowers into by the power and grinding should be vertical

3㎜以上3 mm below 加垫板,垫板两面摩擦面处理方法与构件相同

Plus plate, plate friction dealt with two identical components

1.3.4安装临时螺栓

Installing temporary bolts

连接处采用临时螺栓固定,其螺栓个数为不远接头总数的1/3以上;并每个接头不少于两个,冲钉穿入数量不宜多于临时螺栓的30%.组装时先用冲钉对准孔位,在适当位置插入临时螺栓,用扳手拧紧.不准用高强螺栓兼作临时螺栓,以防螺纹损伤.

Connection temporary fixed bolts, the bolts more than one third of the total number of near joints; And not less than every two joints, nail penetration -- the number should not be
