1.鋼結(jié)構(gòu)螺栓與普通螺栓不同。
1. Steel structure bolts are different from ordinary bolts.
鋼結(jié)構(gòu)扭剪螺栓一般用于連接。 常用的M16-M30。 超大型鋼結(jié)構(gòu)扭剪螺栓的作用不穩(wěn)定，應(yīng)慎用。
Steel structure torsional shear bolts are generally used for connection. Common M16-M30. Torsional shear bolts for super large steel structures are unstable and should be used with caution.
2。螺栓連接建筑結(jié)構(gòu)的主要構(gòu)件一般用于連接鋼結(jié)構(gòu)的扭剪螺栓。
2。 The main components of bolted building structures are generally used to connect the torsional shear bolts of steel structures.
3。一般螺栓可以重復(fù)使用，但鋼結(jié)構(gòu)扭剪螺栓不能重復(fù)使用。
3。 General bolts can be reused, but steel structure torsional shear bolts cannot be reused.
4.鋼結(jié)構(gòu)螺栓采用高強度鋼45鋼8.8s、20MmTiB10.9S。它們是預(yù)應(yīng)力螺栓。它們與扭矩扳手沖突并施加預(yù)應(yīng)力。壓力式螺釘一般采用普通鋼Q235由梅花頭螺栓制成擰緊。
4. High strength steel 45 steel 8.8s and 20MmTiB10.9S shall be used as steel structure bolts. They are prestressed bolts. They conflict with torque wrenches and apply prestress. Pressure type screws are generally made of ordinary steel Q235 and tightened with Torx head bolts.
5。一般螺栓一般為4.4、4.8、5.6、8.8。 鋼結(jié)構(gòu)扭剪螺栓一般為8.8和10.9，大部分為10.9。
5。 Generally, bolts are 4.4, 4.8, 5.6 and 8.8. The torsional shear bolts of steel structures are generally 8.8 and 10.9, and most of them are 10.9.
6。一般螺栓孔不一定比鋼結(jié)構(gòu)扭剪螺栓大。 其實普通的螺栓孔比較小。
6。 Generally, the bolt hole is not necessarily larger than the steel structure torsional shear bolt. In fact, ordinary bolt holes are relatively small.
7.一般A、B級螺栓的螺孔一般只比螺栓大0.3-0.5mm。 C級螺絲孔一般比螺栓大1.0-1.5mm。
7. Generally, the screw hole of Grade A and B bolts is only 0.3-0.5mm larger than the bolt. Grade C screw holes are generally 1.0-1.5mm larger than bolts.
8.干涉鋼結(jié)構(gòu)扭剪螺栓承受干涉?zhèn)鬟f載荷，因此螺釘與螺孔的差值可達1.5-2.0mm
8. The interference steel structure torsional shear bolt bears the interference transfer load, so the difference between the screw and the screw hole can reach 1.5-2.0mm
9.壓力式鋼結(jié)構(gòu)扭剪螺栓的標準傳動特性是保證在正常使用過程中剪力不超過阻力，阻力式鋼結(jié)構(gòu)扭剪螺栓也是如此。
9. The standard transmission characteristic of the pressure type steel structure torsional shear bolt is to ensure that the shear force does not exceed the resistance in the normal use process, so does the resistance type steel structure torsional shear bolt.
