TECHNICAL FIELD

[0001] The utility model relates to a section steel technical field, concretely is a connecting pair for closed section steel. BACKGROUND

[0002] Section steel is widely used in the installation structure of various equipment, as a framework, section steel not only requires sufficient load capacity to improve strength, but also needs to be convenient to disassemble and install, and can speed up the progress of engineering.

[0003] The prior art section steel cannot be stacked, so the load can only be increased by replacing the section steel specification, in addition, the section steel is prone to tilting and collapse when being stacked. INVENTION CONTENTS

[0004] The utility model discloses a connecting pair for closed section steel to solve the problem in the above background.

[0005] To achieve the above object, the utility model provides the following technical scheme: a connecting pair for closed section steel, including section steel body, the upper end surface of section steel body is equipped with the convex, the lower end surface of section steel body is equipped with the inner recess, the outer wall surface of convex can be stacked with the inner wall surface of inner recess, the length direction of convex is equipped with a plurality of upper openings, the length direction of inner recess is equipped with a plurality of lower openings.

[0006] Still include connecting pair, the connecting pair includes limiting nut, inner hexagon nut and limiting cushion block, the lower end surface of limiting nut is equipped with limiting groove, limiting groove is cooperated with convex, when section steel is stacked, inner hexagon nut is used to connect multiple section steels.

[0007] Preferably, the limiting cushion block is trapezoidal in shape, and the limiting cushion block cooperates with the inner recess.

[0008] Preferably, the limiting nut has the same width as the section steel body.

[0009] Compared with the prior art, the utility model has the beneficial effects that: the utility model through setting up connecting pair makes section steel body can be stacked and connected together, thereby increasing the load capacity of section steel, improving the strength, and saving the storage space.

[0014] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0015] Please refer to Figs. 1 to 3 The present application provides a technical solution: a connecting pair for closed profile steel, comprising a profile steel body 1, the upper end face of the profile steel body 1 is provided with a protrusion 2, the lower end face of the profile steel body 1 is provided with an inner recess 3, the outer wall surface of the protrusion 2 and the inner wall surface of the inner recess 3 can be stacked and matched, the length direction of the protrusion 2 is provided with a plurality of upper openings 4, and the length direction of the inner recess 3 is provided with a plurality of lower openings 5.

[0016] Specifically, it further comprises a connecting pair 6, the connecting pair 6 comprises a limiting nut 61, an inner hexagonal nut 62 and a limiting pad 63, the lower end face of the limiting nut 61 is provided with a limiting groove 64, the limiting groove 64 is matched with the protrusion 2, and the inner hexagonal nut 62 is used for connecting a plurality of profile steel bodies 1 when the profile steel bodies 1 are stacked.

[0017] Specifically, the limiting pad 63 is in the shape of a trapezoid, and the limiting pad 63 is matched with the inner recess 3.

[0018] Specifically, the width of the limiting nut 61 is the same as the width of the profile steel body 1.

[0019] The bolt connecting pair is mainly applied to the connection of assembled support and hanger closed profile steel. According to the height of the superposition, there are several different length sizes. The width of the upper and lower limiting pads and the limiting nut is 25-30 mm, the thickness of the limiting pad is 8-10 mm, the thickness of the limiting nut is 10-15 mm, the inner hexagonal bolt is convenient for fastening, the bottom of the superposed profile steel body is the limiting pad, which can be just inserted into the lower recess surface of the profile steel body, the middle of the pad has a hole, which is convenient for the insertion of the inner hexagonal bolt, the top of the superposed profile steel is the limiting nut, which is in the shape of a concave reverse buckle, and is just placed on the convex surface of the profile steel, the middle of the nut is a hole with a thread, which is just matched with the bolt.
