Connecting structure of nested-type composite sectional material

Abstract

The invention discloses a connecting structure of a nested-type composite sectional material. The structure comprises a vertical column and a cross beam of a thin wall column body which is formed by the alternative nesting of a long-strip construction member. The structure is characterized in that the vertical column and the cross beam are vertically connected through a connecting joint; the connecting joint comprises a base plate and a boss; the boss is provided with a hole cavity along the direction vertical to the base plate; the boss and the cross beam are inserted and matched; the base plate and the side wall of the vertical column are connected through a fastening piece; a convex rib is molded along the length direction of the outer side wall of the vertical column; the bottom part of the base plate is provided with a guide groove which can be adaptive to the convex rib; and the outer side wall of the vertical column is also provided with a protrusion which is against the lower edge of the base plate. Compared with the prior art, a detachable connecting joint is used for connecting vertically according to the invention, the base plate and the vertical column of the connecting joint are connected by utilizing a non-regular bolt, not only can the detachable connection be realized, the tight fit between the side walls of the double sides of the vertical column of the composite structure can be ensured, the seamless connection between the side walls of the double sides of the vertical column can be realized, and the strength and intensity of the vertical column can be improved prominently.

Description

technical field [0001] The invention relates to a connection structure, in particular to a vertical connection structure between beams and columns using nested composite profiles. Background technique [0002] In the prior art, the columns or beams used in the frame structure devices such as the garage base frame, the display cabinet frame or the display rack are mostly formed by casting, and the vertical connection between the columns and the beams is mostly fixed by direct welding, or first Weld a connection plate on the column (beam), and then fix the beam (column) to the connection plate. However, when the welding method is used for on-site installation, the workload is heavy, the operation is inconvenient, and the columns or beams are easily deformed by heat. However, in the way of pre-welding the connecting plates on the beams and columns, the beams and columns are not of equal cross-section due to the convexity of the connecting plates. Profiles cause troubles in pac...

AI Technical Summary

Problems solved by technology

However, the connection structure of this patent has many components and a complex structure, and the connection fixture is fixed on the inner wall of the beam, which is inconvenient to assemble and disassemble, and is also not conducive to the positioning of the connection structure relative to the column and the beam
