Steel tube bundle combined structure and manufacturing method thereof

Abstract

The invention relates to a steel tube bundle combined structure and a manufacturing method thereof. The structure comprises outer steel plates which are oppositely arranged, and a plurality of conical holes are formed in the outer steel plates at intervals; the stiffening plates are arranged on the inner sides of the two outer steel plates in a supported mode, the end sides of the stiffening plates are provided with protruding blocks corresponding to the conical holes, the protruding blocks are inserted into the corresponding conical holes, and kerfs are formed in the protruding blocks; the wedge-shaped block is inserted into the protruding block from the cutting seam in the protruding block, and the wedge-shaped block opens the protruding block so that the protruding block can be tightly attached to the hole wall of the conical hole. The stiffening plates and the outer steel plate are fixed through the wedge-shaped blocks, the wedge-shaped blocks are driven into the outer side of the outer steel plate, construction is convenient, the construction speed is high, the outer steel plate is not prone to deformation, and the problems that the number of welded stiffening plates in an existing steel tube bundle combined structure is large, and the welding difficulty is large are solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a steel tube bundle composite structure and a manufacturing method thereof. Background technique [0002] In the prefabricated steel structure house, the commonly used structural system is the steel tube bundle composite structure, but there are many internal stiffening plate welds, and the welding is difficult. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the defects of the prior art, provide a steel tube bundle composite structure and a manufacturing method thereof, and solve the problems of large number of welding seams and difficult welding of the internal stiffening plate of the existing steel tube bundle composite structure. [0004] The technical solution to achieve the above purpose is: [0005] The invention provides a steel tube bundle composite structure, comprising: [0006] The oppositely arranged outer steel...
