来源:http://www.no2design.com 日期:2022-02-19 发布人:admin

钢结构用扭剪型高强度螺栓连接副,主要用于工业与民用建筑、公路与铁路桥梁。塔架、管道支架、起重机械及其他需要采用摩擦型连接的扭剪型高强度螺栓连接副的场合。其特点是螺栓末端多一个十二角体。

Torsional shear type high-strength bolt connection pair for steel structure is mainly used in industrial and civil buildings, highway and railway bridges. Tower, pipe support, hoisting machinery and other occasions where friction type connection of torsional shear type high-strength bolt connection pair is required. The utility model is characterized in that a dodecagonal body is added at the end of the bolt.
安装时,须用特制的电扳手,其上下有两个套筒头,一个套在螺母的六角体上,另一个套在螺栓的十二角体上。拧紧时,对螺母施加顺时针力矩,对螺栓十二角体施加大小相等的逆时针力矩,使螺栓的末端与十二角体之间连接颈部承受扭剪,至颈部剪断为止,则安装完成。
电动扭矩扳手
During installation, a special electric wrench must be used, which has two socket heads at the top and bottom, one on the hexagon of the nut and the other on the dodecagon of the bolt. When tightening, apply a clockwise torque to the nut and an equal counterclockwise torque to the bolt dodecagonal body, so that the connecting neck between the end of the bolt and the dodecagonal body bears torsional shear until the neck is cut off, and the installation is completed.
这种扭剪型高强度螺栓为一次型使用的紧固件,安装后一般不予拆卸。腾驰五金生产的这种产品还挺不错的,这家公司的信誉也不错。
The torsional shear type high-strength bolt is a one-time fastener, which is generally not disassembled after installation. This kind of product produced by tengchi hardware is quite good, and the reputation of this company is also good.
