Description

Technical Field

[0001] The invention relates to the technical field of cross columns for assembled houses, in particular to alloy aluminum cross columns for assembled houses. Background Art

[0002] Prefabricated houses are houses that are partially or completely prefabricated in factories, then transported to construction sites, and assembled by reliable connection. Prefabricated houses include concrete prefabrication, wood structure prefabrication, and metal structure prefabrication. Among metal structure prefabrication, alloy aluminum structure has the characteristics of light weight, high structural strength, and no rust. The cross column is used as a supporting component inside the house, but the existing cross column is not convenient for installation between the inner wall panels. For this reason, we propose alloy aluminum cross columns for prefabricated houses. Summary of the invention

[0003] The purpose of the present invention is to provide an alloy aluminum cross column for a prefabricated house to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an alloy aluminum cross column for a prefabricated house, comprising a column body and a U-shaped convex frame, wherein the column body is hollow, the four corners of the column body are bent inwardly to form a cross, and the U-shaped convex frame is symmetrically fixed to the side wall of the column body.

[0005] Preferably, reinforcing ribs are fixed to the inner wall of the U-shaped convex frame.

[0006] Preferably, the reinforcing ribs are arranged in a trapezoidal shape.

[0007] Preferably, the side walls of the column body are symmetrically fixed with L-shaped clips.

[0008] Preferably, a matching strip matching with the L-shaped clip strip is symmetrically fixed to the side wall of the column body.

[0009] Preferably, the gap between the L-shaped clip strip and the U-shaped convex frame forms a trapezoidal groove.

[0010] Preferably, a card interface is provided on one side of the trapezoidal groove.

[0011] Preferably, the column body, U-shaped convex frame, reinforcing ribs, L-shaped clip strips and matching strips are integrally extruded and formed.

[0012] Preferably, the inner wall of the trapezoidal groove is symmetrically provided with installation and fixing screw holes.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the present invention is in use, the column body and the U-shaped convex frame are sleeved on the upper and lower corner pieces, and the reinforcing ribs on the U-shaped convex frame sleeve are clamped in the grooves opened on the upper and lower corner pieces, and are fixed to the upper and lower corner pieces by installing and fixing screw holes. When installed between the column body and the wall panel, a trapezoidal protrusion is fixed on one end of the wall panel connected to the column body, so that the wall panel is clamped with the U-shaped convex frame and the trapezoidal groove, and can be selectively installed with the four faces of the column body according to the actual room layout. The side where the wall is not installed can be clamped with the trapezoidal groove through a decorative sealing plate. A T-shaped groove is formed between the L-shaped clamping strip and the matching strip fixed on the column body for installing the internal angle plate. This device facilitates the connection between the column body and the wall, is more beautiful to use, and is convenient for people to use. BRIEF DESCRIPTION OF THE DRAWINGS
