[0002] A square profile is a profile with a rectangular or square cross-section perpendicular to its extension direction. The square profile has two annular butt ends and four sides connected between the two annular butt ends. The four sides are connected end to end and the two The two intersect at one side edge, and the adjacent two sides intersecting at one side edge form a side edge. When in use, when more than two square profiles need to be connected, generally the two One of the butt ends of the square profiles is parallel to the side of the other, or the sides of the two square profiles are butted against each other. The strength of the connection structure obtained by this connection method is poor, and it cannot meet the strength requirements of the connector.

Embodiment Construction

[0014] The embodiment of the square profile connection structure of the present invention: such as Figure 1 to Figure 2 As shown, the connection structure includes a first square profile 1 and a second square profile 2, the first square profile and the second square profile can be metal or non-metallic materials, the axis of the first square profile 1 and the second square profile The included angle between the axes of the profiles 2 is 90 degrees. The first square profile 1 and the second square profile 2 both have two annular butt ends and four sides connected between the two butt ends. Connected end to end and intersected at a side edge, the butt end of the second square profile 2 is welded and fixed with the butt side of the first square profile 1, and the side of the second square profile 2 and the butt side of the first square profile 1 are welded. The plane of the two adjacent sides is at 45 degrees, so that the second square profile is placed obliquely, which increase...

Abstract

The invention relates to a square profile butt joint method and a connection structure. A second square profile is provided with a butt joint end, the butt joint end is fixed to the butt joint side face of a first square profile, and a set included angle is formed between the side face of the second square profile and the side face, adjacent to the butt joint side face, of the first square profile. One square profile is obliquely arranged, so that stress size of the connection structure is increased, and bending strength of the connection structure is improved.

Description

technical field [0001] The invention relates to a square profile butt joint method and connection structure. Background technique [0002] A square profile is a profile with a rectangular or square cross-section perpendicular to its extension direction. The square profile has two annular butt ends and four sides connected between the two annular butt ends. The four sides are connected end to end and the two The two intersect at one side edge, and the adjacent two sides intersecting at one side edge form a side edge. When in use, when more than two square profiles need to be connected, generally the two One of the butt end faces of the square profiles is parallel butted with the side of the other side, or the sides of the two square profiles are butted with each other. The strength of the connection structure obtained by this connection method is poor, and it cannot meet the strength requirements of the connector. Contents of the invention [0003] The object of the prese...
