Description

Technical Field

[0001] The utility model relates to the technical field of steel structure components, in particular to a low-deformation and high-strength steel structure component. Background Art

[0002] Steel components refer to steel structure composite components that can bear and transfer loads and are made of steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-shaped steels that are cold-bent or welded and connected through connectors. The existing utility model patent with application number 201821223425.9 discloses a high-strength steel component, which adds I-shaped connecting sleeves on both sides of the I-beam body to improve the support strength; however, in the above structure, there are only two groups of I-shaped connecting sleeves and they are distributed on both sides of the I-beam body. When the I-beam supports the external structure, its two sides are in contact with the external structure and play the main supporting role. There is a gap between the middle part of the I-beam body and the external structure. For the I-beam body, the two ends are subjected to greater force, and the middle is not subjected to force. There is a problem of deformation at both ends of the I-beam, which leads to a decrease in the strength of the I-beam structure and affects the support effect. Utility Model Content

[0006] A further improvement of the low-deformation and high-strength steel structural component of the utility model is that the fixing hole is in a long strip shape.

[0007] A further improvement of the low-deformation high-strength steel structural component of the utility model is that two side plate surfaces of the cold-bent thin-walled steel plate respectively abut against the upper plate and the lower plate.

[0008] A further improvement of the low-deformation high-strength steel structural component of the utility model is that a plurality of groups of cold-bent thin-walled steel plates are arranged evenly and spaced apart along the length direction of the I-beam body.

[0009] A further improvement of the low-deformation high-strength steel structural member of the utility model is that two groups of through holes are arranged on the fixing plate for threaded rods to pass through, and the two groups of through holes are distributed at both ends of the fixing plate.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model opens holes on the upper and lower plates to achieve lightweight, and at the same time, threaded rods are provided and the threaded rods are limited to achieve further support for the upper and lower plates and improve strength; on the other hand, cold-bent thin-walled steel plates are additionally provided to support the edges of the upper and lower plates, and at the same time, the cold-bent thin-walled steel plates are also limited by the threaded rods to ensure stable layout.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1 As shown, a low-deformation high-strength steel structural member includes an I-beam body, and the I-beam body includes an upper plate 1, a lower plate 2, and an intermediate plate 3 connecting the upper plate and the lower plate. A plurality of reinforcing plates 4 are arranged between the upper plate and the lower plate, and the reinforcing plates are evenly distributed on both sides of the intermediate plate. The upper and lower ends of the reinforcing plates respectively abut against the upper and lower plates, and the reinforcing plates and the upper and lower plates can be connected by welding. Fixing holes 10 are arranged on both sides of the upper plate and the lower plate, and a horizontally arranged fixing groove 5 is arranged in the middle of the reinforcing plate. A C-shaped cold-bent thin-walled steel plate 6 is also arranged between the upper plate and the lower plate, and the cold-bent thin-walled steel plate has an opening facing outward, and a fixing plate is arranged on the side of the cold-bent thin-walled steel plate away from the opening, and the fixing plate is inserted into the fixing groove. A threaded rod 8 is arranged between the fixing holes of the upper plate and the lower plate, and the threaded rod passes through the fixing plate. Four sets of nuts 9 are screwed on the threaded rod, and respectively abut against the upper end side of the lower plate, the lower end side of the fixing plate, the upper end side of the fixing plate, and the lower end side of the upper plate.

[0016] Preferably, the fixing holes are in the shape of long strips, which is conducive to realizing lightweight steel structures.

[0017] The two side surfaces of the cold-bent thin-walled steel plate are against the upper plate and the lower plate respectively, which supports the upper and lower plates, thereby achieving the purpose of enhancing the strength of the I-beam.

[0018] Furthermore, multiple groups of cold-bent thin-walled steel plates are arranged evenly spaced along the length direction of the I-beam body. Two groups of perforations are arranged on the fixing plate for the threaded rod to pass through, and the two groups of perforations are distributed at both ends of the fixing plate. Multiple groups of cold-bent thin-walled steel plates replace the overall long strip steel plates, which saves materials while ensuring the support strength, and is also conducive to the threaded limit of the nut on the threaded rod.

[0019] The working principle of the utility model is as follows: cold-bent thin-walled steel plates are arranged so that the fixing plates can be inserted into the fixing grooves of some reinforcing plates, and then the threaded rods are passed through the fixing holes and the fixing plates, and nuts are arranged while passing through. Afterwards, the nuts are rotated to position the threaded rods relative to the upper and lower plates, and the fixing plates are also limited. On the whole, the support for the upper and lower plates of the I-beam body is strengthened by the cold-bent thin-walled steel plates and the threaded rods, thereby improving the structural strength, preventing deformation, and ensuring the quality.

[0020] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
