Mounting method of beam-column connecting joints of prefabricated house steel structure

REN YURONG

The invention relates to steel structure beam-column connection, and particularly relates to a mounting method of beam-column connecting joints of a prefabricated house steel structure. The mounting method comprises the steps that welding seams are calculated, and blanking is conducted in a manufacturing factory for standby application according to the specification and the plate thickness of selected clamping head plates; one end of each selected clamping head plate is welded to the end of a steel beam; after the steel beam welded with the clamping head plates is hoisted to the mounting position, the other ends of the clamping head plates are erected on a bracket of a steel column, and then a hoisting tool is removed; the joints of the beam column are connected by mounting workers through bolts; and the connecting joints are welded finally according to the drawing requirements, and mounting of the whole beam column is completed. According to the mounting method of the beam-column connecting joints of the prefabricated house steel structure, hoisting tools are not needed for whole-process cooperation, the mounting workers can conduct grouping operation, and the mounting efficiency is high.

本发明涉及钢结构梁柱连接，尤其是一种装配式住宅钢结构的梁柱连接节点的安装方法，计算焊缝，根据所选卡头板的规格及板厚，在制造厂下料备用；将选好的卡头板的一端与钢梁的端部焊接；将焊接好卡头板的钢梁吊装至安装位置后，将卡头板的另一端搭在钢柱的牛腿上，然后解除吊具；安装工人用螺栓将梁柱的节点连接；根据图纸要求对连接节点最后施焊，整个梁柱安装完毕。本发明不用吊装工具全程配合，而且安装工人可以分组作业，安装效率高。
