扭剪螺栓就是鋼結(jié)構(gòu)螺栓，也屬于高強度螺栓，也是標(biāo)準(zhǔn)件的一種。而了解鋼結(jié)構(gòu)螺栓主要看鋼結(jié)構(gòu)螺栓分類、施工。
Torsional shear bolts are steel structural bolts, which also belong to high-strength bolts and are a type of standard components. Understanding steel structural bolts mainly depends on their classification and construction.
一、鋼結(jié)構(gòu)螺栓運用
1、 Application of Steel Structure Bolts
鋼結(jié)構(gòu)螺栓主要應(yīng)用在鋼結(jié)構(gòu)工程上,用來連接鋼結(jié)構(gòu)鋼板的連接點。鋼結(jié)構(gòu)螺栓是一種高強度的螺栓，也是標(biāo)準(zhǔn)件的一種。緊固性能比較好，用于鋼結(jié)構(gòu)上，工程上，使緊固作用的。一般鋼結(jié)構(gòu)上，要求的鋼結(jié)構(gòu)螺栓都是8.8級以上的，還有10.9級，12.9級的，全部都是高強度的鋼結(jié)構(gòu)螺栓，有時鋼結(jié)構(gòu)上的螺栓是不需要電鍍的，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、鋼結(jié)構(gòu)螺栓分類
2、 Classification of steel structural bolts
鋼結(jié)構(gòu)螺栓分為扭剪型高強螺栓和大六角高強螺栓,大六角高強螺栓屬于普通螺絲的高強度級,而扭剪型高強螺栓則是大六角高強螺栓的改進型,為了更好施工。
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、鋼結(jié)構(gòu)螺栓施工
3、 Steel structure bolt construction
鋼結(jié)構(gòu)螺栓的施工建議先初緊后終緊,初緊鋼結(jié)構(gòu)螺栓需用沖擊型電動扳手或扭矩可調(diào)電動扳手;而終緊鋼結(jié)構(gòu)螺栓有嚴格的要求,終緊扭剪型鋼結(jié)構(gòu)螺栓建議用扭剪型電動扳手,終緊扭矩型鋼結(jié)構(gòu)螺栓建議用扭矩型電動扳手。
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.
