Shear bolts are steel structural bolts, which are also high-strength bolts and a type of standard component. Understanding steel structural bolts mainly depends on their classification and construction. If you are a layman, if you need to use these accessories, it is important to have a thorough understanding of the relevant knowledge in advance, so as not to choose the wrong product. Today, let's take a comprehensive analysis of steel structural bolts with Tian Sheng's 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 structural bolts are mainly used in steel structural engineering to connect the connection points of steel structural steel plates. Steel structural bolts are high-strength bolts and are also a type of standard component. The fastening performance is relatively good, used in steel structures and engineering, to enhance the fastening effect. On general steel structures, the required steel structural bolts are grade 8.8 or above, as well as grade 10.9 and 12.9, all of which are high-strength steel structural bolts. Sometimes, the bolts on steel structures do not need to be electroplated, and it is OK to use the natural color.

二、钢结构螺栓分类

2、 Classification of steel structural 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。

Steel structural bolts are divided into torsional shear type high-strength bolts and large hexagonal high-strength bolts. Large hexagonal high-strength bolts belong to the high-strength grade of ordinary screws, while torsional shear type high-strength bolts are an improved type of large hexagonal high-strength bolts for better construction.

三、钢结构螺栓施工

3、 Steel structure bolt construction

钢结构螺栓的施工必须先初紧后终紧,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必须用扭剪型电动扳手,终紧扭矩型钢结构螺栓必须用扭矩型电动扳手。

The construction of steel structural bolts must be initially tightened before final tightening. The initial tightening of steel structural bolts requires the use of impact type electric wrenches or torque adjustable electric wrenches; And there are strict requirements for final tightening of steel structural bolts. Final tightening of torsion shear type steel structural bolts must use torsion shear type electric wrenches, and final tightening of torque type steel structural bolts must use torque type electric wrenches.
