Description

Technical Field

[0001] This application relates to the technical field of steel structures, and particularly to a type of steel structure. Background Art

[0002] Section steel is a type of bar steel with a certain cross-sectional shape and size, and is one of the four major varieties of steel (plate, pipe, section, wire). According to the cross-sectional shape, section steel is divided into simple cross-section section steel and complex cross-section section steel. The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beam, channel steel, rail, window frame steel, bent section steel, etc. According to the smelting quality of steel, section steel is divided into ordinary section steel and high-quality section steel. Ordinary section steel is further divided into large section steel, medium section steel, and small section steel according to the current metal product catalog. Ordinary section steel can also be divided into I-beam, channel steel, angle steel, round steel, etc. according to its cross-sectional shape. C-section steel is automatically processed and formed by a C-section steel forming machine. The C-section steel forming machine can automatically complete the forming process of C-section steel according to the given C-section steel size. Section steel is widely used in the fields of construction, engineering, manufacturing, etc., and has the advantages of stable structure, high strength, light weight, and convenient processing.

[0003] During the production and use of existing section steel, the internal stress and external force acting on the section steel will cause the structural strength of the section steel to decrease, resulting in the deformation of the section steel during use, which will further affect the stability and safety of the section steel during use. Utility Model Content

[0004] In order to ensure the structural strength of section steel during use, prevent the deformation of section steel during use, and improve the stability and safety of section steel during use, this application provides a type of steel structure.

[0005] This application provides a type of steel structure, adopting the following technical solutions:

[0006] A type of steel structure includes a bottom plate. On both sides of the bottom plate in the width direction, waist plates are provided, and each waist plate is perpendicular to the bottom plate. Long waist holes and short waist holes are penetrated through the bottom plate, and the long waist holes and the short waist holes are alternately arranged at intervals along the length direction of the bottom plate. On each waist plate, several groups of assembly through holes are provided, and each group of assembly through holes is arranged at intervals in a row along the length direction of the waist plate.

[0007] By adopting the above technical solutions, the provisions of the long waist hole, short waist hole and assembly through-hole contribute to increasing the shear strength and stiffness of the bottom plate, thus helping to ensure the structural strength of the profiled steel structure during use, thereby helping to prevent the profiled steel structure from deforming during use, and further helping to improve the stability and safety of the profiled steel structure during use. The provisions of the long waist hole, short waist hole and assembly through-hole also contribute to reducing the self-weight of the bottom plate, thus helping to improve the overall light weight of the profiled steel structure. The provisions of the long waist hole, short waist hole and assembly through-hole also contribute to enhancing the convenience of the mating connection between the profiled steel structure and other components.

[0008] In a specific feasible embodiment, the assembly through-hole is a waist-shaped hole or a hexagonal hole, and the center distance between two adjacent assembly through-holes is 25 mm.

[0009] By adopting the above technical solutions, setting the assembly through-hole as a waist-shaped hole helps to optimize the stress distribution, thus helping to prevent stress concentration, and further helping to improve the overall stiffness of the profiled steel structure, improving the stability and safety of the profiled steel structure during use. Setting the assembly through-hole as a hexagonal hole helps to increase the overall strength of the profiled steel structure, improving the stability and safety of the profiled steel structure during use, and at the same time also helps to enhance the convenience and assembly accuracy of the profiled steel structure during assembly.

[0010] In a specific feasible embodiment, the width of the bottom plate is 47 mm, the width of the waist plate is 50 mm, the thicknesses of the bottom plate and the waist plate are both 2 mm, and two groups of assembly through-holes are arranged along the width direction of the waist plate.

[0014] In a specific possible implementation scheme, a wing plate is arranged on the side of each waist plate away from the bottom plate, each wing plate is extended toward the middle position of the two waist plates, and the side of the wing plate facing the bottom plate is curved, and the side of the wing plate away from the bottom plate is straight and parallel to the bottom plate.

[0015] By adopting the above technical solution, the provision of the wing plate helps to strengthen the bearing capacity of the steel structure, thereby helping to prevent the steel structure from deforming during use, and further helping to improve the stability and safety of the steel structure during use.
