Problems solved by technology

[0004] The purpose of the present invention is realized, and the main improvement is that two H-shaped rods are welded and welded separately, and then one of the H-shaped rods is cut along the center of the web into two identical T-shaped pieces, and then the two identical T-shaped Butt welded to the center of the web of the H-shaped member to form a plate-jointed cross bar. The deformation of the plate-joined cross column obtained by this method is small, easy to correct, and the workload is small. Purpose of the invention

Embodiment 1

[0013] Embodiment 1: Referring to Figures 4 and 5, each steel plate is cut according to the design requirements, and the H-shaped rods are welded by alternating diagonal cycles, and the center of the web 1 of one H-shaped rod is fixed at a distance of 400mm when cutting. Point solid length 80 ~ 100mm, first flame cut into a point connection shape 1.1, welded into H rods, then cut along this point connection line to form 2 identical T-shaped, and finally put the 2 T-shaped opposite to another H The center of the web plate of the type bar is formed by alternating diagonal circular welding to form a cross column. When welding, use the angle template to check the verticality at any time, adjust the welding sequence and welding amount, and make a slight correction to the specified requirements after welding. hole.

Embodiment 2

[0014] Embodiment 2: If the material does not fit together, the H-shaped web that needs to be cut for welding is cut into two single strips, first straightened and leveled, and the two single strips are spot welded together to form the web 1, and then Weld the two wing plates 2 to make H-shaped rods, then cut them into two T-shaped rods according to the spot welding connection line, and assemble and weld them in the center of the web of the H-shaped rods.

Abstract

The invention relates to an improved method of making a steel structure plate assembly crisscrossed post, which is characterized in that the single components are made by first assembling and welding two H-shaped bars, and then cutting one of the two H-shaped bars into two same T shapes along the center of a web plate; during assembly, welding and shaping, the two same T shapes cut are welded and fixed in the H-shaped bar web plate through diagonal alternation and circulation. The method of the invention changes the ordinary practice of the prior art by first making two H-shaped bars and then cutting one of the H-shaped bars; in this way, two faces of the T-shaped are in parallel and are well vertical to the web plate, so as to reduce the welding deformation of transverse plates and vertical plates and effectively ensure the verticality between wing plates and the web plate, straightness and torsion resistance of the assembly bars. And upon final assembly and welding, through diagonal alternation and circulation welding, the assembly deformation is reduced and 100 percent hole correction can be achieved basically without need of extra calibration, which greatly improve the on-site assembly production efficiency.

Description

technical field [0001] The invention relates to the improvement of the preparation method of the steel structure plate cross column, in particular to a method for preparing the plate cross column with small welding deformation, good shape and dimension accuracy of the obtained plate cross column, accurate alignment of connecting hole groups, and convenient installation . Background technique [0002] The cross-column assembled by the middle plate of the steel structure (Fig. 1) is an important main column in the steel structure frame. In order to ensure the accurate alignment of the hole groups between the upper and lower columns and between the cross-column and the beam when the steel structure is installed, and a high perforation rate , The straightness, verticality, and twist of the cross column are extremely demanding. If there is a deviation, it will make it difficult to assemble and align the holes. Manual hole repair is required to ensure the alignment rate, which gre...
