Lightweight U-shaped steel beam structure

Abstract

The invention relates to a lightweight U-shaped steel beam structure which belongs to the technical field of steel structure building members. The adopted technical scheme is as follows: U-shaped steel beam lateral plate edges are symmetrically arranged in the two side directions of a U-shaped steel beam baseplate; punching a row of equilateral triangle-shaped through holes at the middle of each U-shaped steel beam lateral plate edge; and the equilateral triangle-shaped through holes are in positive-reverse arrangement alternately, a hem which is folded to the same side is arranged at a mouth part of each equilateral triangle-shaped through hole, and a long strip-shaped convex rib which is opposite to the direction of the hem is punched between every two equilateral triangle-shaped through holes. The U-shaped steel beam structure can not only reduce the weight of a steel beam, but also increase the loading capacity of the steel beam, be conductive to safety of a building and reduce the construction cost of the building.

Description

technical field [0001] The invention relates to a U-shaped steel beam structure, which belongs to the technical field of steel structure building components. Background technique [0002] U-shaped steel beam is a structural part widely used in steel structure buildings. Its main function in building components is as a supporting beam for the roof of steel structure buildings. It can be seen from its role that it mainly bears bending stress. [0003] At present, it is known that the structure of the U-shaped steel beam is a solid web structure. Due to the bending stress borne by the U-shaped steel beam, it can be known from the mechanical properties of the material that the bending stress mainly acts on the upper and lower sides of the steel beam side plate. On the side, the bending moment of the material in the middle part is zero or very small, so the material in the middle part of the U-shaped steel beam of the solid web structure is not only a waste; at the same time.

[0003] At present, it is known that the structure of the U-shaped steel beam is a solid web structure. Due to the bending stress borne by the U-shaped steel beam, it can be known from the mechanical properties of the material that the bending stress mainly acts on the upper and lower sides of the steel beam side plate. side, the material in the middle part bears zero or very little bending moment, so the material in the middle part of the U-shaped steel beam with solid web structure is not only a waste;

Its existence will also increase the weight of the building, which is not conducive to saving costs; at the same time, it will also affect the safety performance of the building to a certain extent
