Description

Technical Field

[0001] This utility model belongs to the technical field of C-shaped steel, specifically relating to an irregularly shaped C-shaped steel. Background Technology

[0002] C-shaped steel is widely used in purlins and wall beams of steel structure buildings. In photovoltaic systems, C-shaped steel can be used in guide rails and brackets of ground power stations and photovoltaic roofs.

[0003] Traditional C-shaped steel has its ribs on one side, which can cause it to twist under compression when the span is large, thus affecting the structural rigidity. In addition, traditional C-shaped steel does not have the space for equipment such as fire pipe supports, so the other equipment to be installed needs to be suspended from the lower part of the C-shaped steel, which reduces the overall height of the steel structure. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide an irregular C-shaped steel.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: an irregular C-shaped steel, including a small bending part, a large bending part and an intermediate support part, wherein the small bending part is located at the top of the intermediate support part and the large bending part is located at the bottom of the intermediate support part. Each of the small bending part and the large bending part includes a supporting inclined side and a supporting plane. The supporting planes in the small bending part and the large bending part are arranged outwards, and the supporting inclined side is arranged inwards. The intermediate support part is connected to the supporting inclined side in the small bending part and the large bending part respectively. The supporting planes in the small bending part and the large bending part are arranged parallel to each other. The intermediate support part is arranged perpendicular to the two supporting planes. Multiple sets of connecting holes and wire holes are equidistantly provided on the intermediate support part.

[0006] Preferably, the small bend, the large bend, and the intermediate support are all integral structures.

[0007] Preferably, each group has two connecting holes, and the spacing between the threaded holes is greater than the spacing between the connecting holes.

[0008] Preferably, the width of the bending plane in the small bend is smaller than that in the large bend.

[0009] The beneficial effects of this utility model are as follows: By setting small and large bends in the C-shaped steel, and placing the traditional web, i.e., the intermediate support, in the middle of the small and large bends, this structure can provide support in the middle of the small and large bends when under pressure, effectively preventing overall torsion; by setting multiple C-shaped steel connection holes and wire holes in the middle of the C-shaped steel, the wire holes can be used to pass through transverse pipes, and pipe racks can be installed on the C-shaped steel connection holes, which facilitates the installation of pipelines, thereby improving the installation position and avoiding loss of floor height.

[0013] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0014] Example: An irregularly shaped C-shaped steel, such as Figures 1-2 As shown, the device includes a small bend 7, a large bend 8, and a middle support 9. The small bend 7 is located at the top of the middle support 9, and the large bend 8 is located at the bottom of the middle support 9. Both the small bend 7 and the large bend 8 include a supporting inclined side 12 and a supporting plane 13. The supporting plane 13 in the small bend 7 and the large bend 8 faces outward, and the supporting inclined side faces inward. The middle support 9 is connected to the supporting inclined side 12 in the small bend 7 and the large bend 8, respectively. The supporting planes 13 in the small bend 7 and the large bend 8 are arranged parallel to each other. The middle support 9 is perpendicular to the two supporting planes 13. Multiple sets of connecting holes 10 and threading holes 11 are equidistantly provided on the middle support 9.

[0015] The small bend 7, the large bend 8, and the intermediate support 9 are all integral structures; each group of connecting holes 10 has two holes, and the spacing between the threading holes 11 is greater than the spacing between the connecting holes 10; the width of the bending plane in the small bend 7 is smaller than the bending plane in the large bend 7.

[0016] The principle of this utility model:

[0017] By setting small bends 7 and large bends 8 on the C-shaped steel, and placing the traditional web and intermediate support 9 in the middle of the small bends 7 and large bends 8, this structure can effectively prevent the whole structure from twisting when under pressure, as the intermediate support 9 can provide support in the middle of the small bends 7 and large bends 8. By setting multiple connecting holes 10 and wire holes 11 in the middle of the C-shaped steel, the wire holes 11 can be used to pass through transverse pipes, and pipe supports can be installed on the connecting holes 10 to facilitate the installation of pipelines, thereby improving the installation position and avoiding loss of floor height.

Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
