Assembling method of steel structure cantilever beam and beam column connecting joint

WANG YUE

The invention relates to an assembling method of a steel structure cantilever beam and beam column connecting joint, and belongs to the technical field of building construction. The method includes the following steps that S1, a steel structure column and a steel structure beam are prefabricated, two fixing plates are welded on the steel structure column, a rib plate is welded to the steel structure beam, a reinforcing plate is welded at the bottom of the rib plate, and the side, close to the end of the steel structure beam, of the reinforcing plate inclines downwards; S2, the steel structurecolumn is fixed, wherein the steel structure beam is hoisted and fixed; S3, the steel structure beam is hoisted, wherein the steel structure beam is hoisted; S4, the steel structure beam is fixed, wherein the fixing plates and the steel structure beam are fixed through fixing bolts and fixing nuts; and S5, the steel structure beam is reinforced, wherein the two ends of a supporting plate are welded to the steel structure column and the steel structure beam respectively, so that the top surface of the supporting plate abuts against the bottom surface of the reinforcing plate, the supporting plate and the reinforcing plate are fixed through reinforcing bolts sand reinforcing nuts, and the effect of improving the structural strength of the beam and column connecting joint is achieved.

本发明涉及一种钢结构悬臂梁梁柱连接节点的装配方法，属于建筑施工的技术领域，包括有以下步骤：S1预制钢结构柱和钢结构梁：在钢结构柱上焊接两个固定板，在钢结构梁上焊接肋板，并在肋板底部焊接加强板，加强板靠近钢结构梁端头的一侧向下倾斜；S2固定钢结构柱：将钢结构柱进行吊装并固定；S3吊装钢结构梁：对钢结构梁进行吊装；S4固定钢结构梁：采用固定螺栓和固定螺母将固定板与钢结构梁进行固定；S5加强钢结构梁：将支撑板的两端分别焊接在钢结构柱和钢结构梁上，使支撑板的顶面与加强板的底面抵接，采用加强螺栓和加强螺母将支撑板与加强板进行固定，达到提高梁柱链接节点结构强度的效果。
