高强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.

High strength bolts are mainly used in steel structure engineering to connect the connection points of steel structure steel plates
高强螺栓的一个非常重要的特点就是限单次使用,一般用于连接,严禁重复使用!
A very important feature of high-strength bolts is that they are limited to single use. They are generally used for permanent connection. Reuse is strictly prohibited!
高强螺栓分类:
Classification of high strength bolts:
按受力状态分为:
According to the stress state, it is divided into:
摩擦型和承压型;
Friction type and pressure bearing type;
按施工工艺分为:扭剪型高强螺栓和大六角高强螺栓。
According to the construction process, it is divided into torsional shear high-strength bolt and large hexagon high-strength bolt.
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.
Large hexagon high-strength bolt belongs to the high-strength grade of ordinary screw, while torsion shear high-strength bolt is an improved type of large hexagon high-strength bolt for better construction
扭剪扳手
高强螺栓的施工必须先初紧后终紧,初紧高强螺栓需用冲击型电动扳手或扭矩可调电动扳手;而终紧高强螺栓有严格的要求,终紧扭剪型高强螺栓必须用扭剪型电动扳手,终紧扭矩型高强螺栓必须用扭矩型电动扳手.
The construction of high-strength bolts must be tightened first and then finally. The impact electric wrench or torque adjustable electric wrench is required for the initial tightening of high-strength bolts; The final tightening of high-strength bolts has strict requirements. The final tightening of torsional shear high-strength bolts must use torsional shear electric wrench, and the final tightening of torque high-strength bolts must use torque electric wrench
大六角强螺栓?由一个螺栓,一个螺母,两个垫圈组成。
Large hexagon bolt? It consists of a bolt, a nut and two washers.
扭剪型高强螺栓?由一个螺栓,一个螺母,一个垫圈组成。
Torsional shear high strength bolt? It consists of a bolt, a nut and a washer.
用高强度钢制造的,或者需要施以较大预紧力的螺栓,皆可称为高强度螺栓.高强度螺栓多用于桥梁、钢轨、高压及超高压设备的连接.这种螺栓的断裂多为脆性断裂.应用于超高压设备上的高强度螺栓,为了保证容器的密封,需要施以较大的预应力.?
Bolts made of high strength steel or requiring large preload can be called high strength bolts High strength bolts are mostly used for the connection of bridges, rails, high pressure and ultra-high pressure equipment The fracture of this kind of bolt is brittle fracture For high-strength bolts applied to ultra-high pressure equipment, large prestress is required to ensure the sealing of the container?
关于高强度螺栓的几个概念1.按规定螺栓的性能等级在8.8级以上者,称为高强度螺栓.现国家标准只罗列到M39,对于大尺寸规格,特别是长度大于%10~15倍的高强度螺栓,国内生产尚属短线.
Some concepts about high strength bolt 1 According to the regulations, the performance grade of the bolt is above grade 8.8, which is called high-strength bolt At present, the national standard only lists M39. For large-size specifications, especially high-strength bolts with length greater than% 10 ~ 15 times, domestic production is still short-term
