钢结构扭剪螺栓和普通螺栓之间的区别

来源:https://www.xjnwz.com 日期:2021-11-11 发布人:admin

1.钢结构扭剪螺栓与普通螺栓不同。钢结构扭剪螺栓通常用于连接。常用的M16-M30。非常大尺寸的钢结构扭剪螺栓性能不稳定,应谨慎使用。

1. Torsion shear bolts of steel structure are different from ordinary bolts. Torsional shear bolts for steel structures are usually used for connections. Common m16-m30. The performance of torsional shear bolts of very large steel structures is unstable and should be used with caution.
2.螺栓连接的建筑结构的主要部件,通常用于连接钢结构扭剪螺栓。
2. The main components of bolted building structures are usually used to connect torsional shear bolts of steel structures.

3.普通螺栓可以重复使用,钢结构扭剪螺栓不能重复使用。
3.Ordinary bolts can be reused, and steel structure torsion shear bolts cannot be reused.
4.钢结构扭剪螺栓由高强度钢(45钢(8.8s),20MmTiB(10.9S))制成,是预应力螺栓,与扭矩扳手摩擦,施加预应力,压力型螺丝从梅花头螺栓通常由普通钢(Q235)制成,刚刚拧紧。
4. The torsion shear bolt of steel structure is made of high-strength steel (45 steel (8.8s), 20 mmtib (10.9s)). It is a prestressed bolt. It rubs with a torque wrench to apply prestress. The pressure screw is made of Torx head bolt, which is usually made of ordinary steel (Q235) and has just been tightened.
5.普通螺栓通常为4.4,4.8,5.6和8.8。钢结构扭剪螺栓通常为8.8和10.9,其中大部分为10.9。
5. Ordinary bolts are usually 4.4, 4.8, 5.6 and 8.8. Torsional shear bolts for steel structures are usually 8.8 and 10.9, most of which are 10.9.
6.普通螺栓孔不一定比钢结构扭剪螺栓大。其实普通的螺栓螺栓孔比较小。
6. Ordinary bolt holes are not necessarily larger than steel structure torsional shear bolts. In fact, ordinary bolt holes are relatively small.
7.普通螺栓A,B级螺丝孔一般只比螺栓大0.3-0.5mm。 C级螺丝孔一般大于螺栓1.0-1.5mm。
7. Ordinary bolt A and B screw holes are generally only 0.3-0.5mm larger than bolts. Class C screw holes are generally 1.0-1.5mm larger than bolts.
8.摩擦式钢结构扭剪螺栓通过摩擦传动载荷,因此螺杆和螺杆孔的差异可达1.5-2.0mm。
8. Friction type steel structure torsional shear bolt drives load through friction, so the difference between screw and screw hole can reach 1.5-2.0mm.
9.压力型钢结构扭剪螺栓的标准传动特性是确保在正常使用时,剪切力不超过摩擦力,摩擦式钢结构扭剪螺栓也一样。当负载再次增加时,连接板之间的连接相对滑动取决于螺丝的剪切力和孔壁的压力,而普通螺栓,因此螺杆与螺丝孔之间的差异稍微小一些,为1.0-1.5mm。
9. The standard transmission characteristic of pressure steel structure torsional shear bolt is to ensure that the shear force does not exceed the friction force during normal use, and so does the friction steel structure torsional shear bolt. When the load increases again, the relative sliding of the connection between the connecting plates depends on the shear force of the screw and the pressure of the hole wall, while for ordinary bolts, the difference between the screw and the screw hole is slightly smaller, which is 1.0-1.5mm.
