Fabricated waist beam

The invention provides an assembly type waist beam which comprises waist beam bodies, at least one end of each waist beam body is a butt joint end, and the adjacent waist beam bodies are detachably connected at the butt joint ends. The two sides of each waist beam body are connecting ends, and the adjacent waist beam bodies are detachably connected at the connecting ends. According to the assembly type waist beam, butt joint or connection between the waist beams is completed in a high-strength bolt connection mode, and a welding mode in the prior art is abandoned, so that it is guaranteed that operation is more convenient, repeated use can be achieved, and the quality of the waist beam is guaranteed due to the influence of high temperature on materials during welding. 本发明提供了一种装配式腰梁，包括腰梁主体，所述腰梁主体的至少一端为对接端，且相邻的腰梁主体在此对接端构成可拆卸连接；以及所述腰梁主体的两侧为连接端，且相邻的腰梁主体在此连接端构成可拆卸连接。本发明提出的装配式腰梁，通过以高强螺栓连接方式，完成了腰梁之间的对接或连接，摒弃了现有技术中焊接的方式，从而保证操作更加方便，且可重复使用，以及焊接由于高温对材料的影响，以保证腰梁的质量。
