作业准备—选择螺栓并配套—接头组装—安装临时螺栓—安装高强螺栓—高强螺栓紧固—检查验收
Operation preparation - selecting bolts and matching - joint assembly - installing temporary bolts - installing high-strength bolts - fastening high-strength bolts - inspection and acceptance
螺栓长度的选择:扭剪型高强螺栓的长度为螺栓头根部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，并且紧固后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5mm的整倍数。
Selection of bolt length: the length of the torsional shear type high-strength bolt is the length from the root of the bolt head to the notch of the bolt quincunx. The length of the selected bolt shall be the thickness of the fastening connecting plate plus the thickness of one nut and one washer, and the surplus length of not less than two threads shall be exposed after fastening. Generally, the thickness of the connecting plate plus the increased length in Table 5-2 shall be taken as an integral multiple of 5mm.
扭剪螺栓就是钢结构螺栓，也属于高强度螺栓，也是标准件的一种。而了解钢结构螺栓主要看钢结构螺栓分类、施工。如果你是外行，如有需要用到这些配件的时候一定要提前了解一下相关知识，只有这样才不会选错产品。今天就随天圣小编来看看钢结构螺栓解析，以供大家参考。
Torsional shear bolt is a kind of steel structure bolt, which is also a high-strength bolt and a standard part. The understanding of steel structure bolts mainly depends on the classification and construction of steel structure bolts. If you are a layman, if you need to use these accessories, you must know the relevant knowledge in advance, so that you can not choose the wrong product. Today, we will take a look at the comprehensive analysis of steel structure bolts with Tiansheng small editor for your reference.
一、钢结构螺栓运用
1、 Application of steel structure bolts
钢结构螺栓主要应用在钢结构工程上,用来连接钢结构钢板的连接点。钢结构螺栓是一种高强度的螺栓，也是标准件的一种。紧固性能比较好，用于钢结构上，工程上，使紧固作用的。一般钢结构上，要求的钢结构螺栓都是8.8级以上的，还有10.9级，12.9级的，全部都是高强度的钢结构螺栓，有时钢结构上的螺栓是不需要电镀的，用本色就OK。
Steel structure bolts are mainly used in steel structure engineering to connect the connection points of steel structure plates. The steel structure bolt is a kind of high-strength bolt and also a standard part. The fastening performance is relatively good. It is used for steel structure and engineering to ensure the fastening effect. For general steel structures, all required steel structure bolts are above Grade 8.8, as well as Grade 10.9 and 12.9, all of which are high-strength steel structure bolts. Sometimes the bolts on steel structures do not need electroplating, and it is OK to use the natural color.
二、钢结构螺栓分类
2、 Classification of steel structure bolts
钢结构螺栓分为扭剪型高强螺栓和大六角高强螺栓,大六角高强螺栓属于普通螺丝的高强度级,而扭剪型高强螺栓则是大六角高强螺栓的改进型,为了更好施工。
The steel structure bolts are divided into torsional shear high-strength bolts and large hexagon high-strength bolts. The large hexagon high-strength bolts belong to the high strength level of ordinary screws, while the torsional shear high-strength bolts are improved types of large hexagon high-strength bolts for better construction.
三、钢结构螺栓施工
3、 Steel structure bolt construction
钢结构螺栓的施工需要先初紧后终紧,初紧钢结构螺栓需用冲击型电动扳手或扭矩可调电动扳手;而终紧钢结构螺栓有严格的要求,终紧扭剪型钢结构螺栓需要用扭剪型电动扳手,终紧扭矩型钢结构螺栓需要用扭矩型电动扳手。
The construction of steel structure bolts requires initial tightening before final tightening, and the initial tightening of steel structure bolts requires impact type electric wrench or torque adjustable electric wrench; The final tightening of steel structure bolts has strict requirements. The final tightening of torsional shear type steel structure bolts requires the use of a torsional shear type electric wrench, and the final tightening of torque type steel structure bolts requires the use of a torque type electric wrench.
The above is a detailed introduction of the special wrench for torsional shear bolts, and I hope it will be helpful to you. If you have any questions, please contact us. We will provide you with professional services https://www.xjnwz.com
