Connector connecting key of fabricated steel support and assembling method

ZHANG YUE

The invention discloses a connector connecting key of a fabricated steel support and an assembling method. The connector connecting key is of a rectangular tubular structure, steel is connected to a part at a support seam in a sleeving mode, and a connecting seam of two H-shaped steel supports is covered; the inner side section of the cross section of the connector connecting key is slightly larger than the cross section of the steel supporting part and can move in the axial direction of the steel supporting part; holes are regularly formed in the contact surface side of the H-shaped steel supporting part according to the arrangement of bolt holes of the H-shaped steel supporting part; the joint connecting key is sleeved at the joint of the steel support or in the middle of the steel support, and is assembled with the H-shaped steel support through bolts; and a tie beam or tie bar connecting end is arranged in the lateral direction of the connector connecting key and is connected with the tie beam or tie bar on the steel support on the adjacent side to form a truss structure. The connector connecting key of the fabricated steel support has green, environment-friendly, safe and reliable social benefits, meanwhile, the integrity and the manufacturing cost of steel support assembly can be greatly improved, the assembling difficulty is reduced, the construction period is shortened, and great economic value and social benefits are achieved.

本发明公开了一种装配式钢支撑的接头连接键与组装方法，其接头连接键是矩形管状结构，套接钢于支撑接缝处的构件，将两根H型钢支撑连接缝覆盖；接头连接键的横截面的内侧断面略大于钢支撑构件的横截面，能沿钢支撑构件的轴向移动；与钢支撑构件接触面侧按H型钢支撑构件布置螺栓孔规则布孔；接头连接键套接在钢支撑接头处或钢支撑的中部，通过螺栓与H型钢支撑组装在一起；接头连接键的侧向设置有系梁或系杆连接端，与相邻侧钢支撑上的系梁或系杆连接，形成桁架结构。该专利具有绿色、环保和安全可靠的社会效益，同时能大大提高钢支撑组装的整体性和造价，减少了组装的难度和缩短工期，具有重大的经济价值和社会效益。
