Description

Technical Field

[0001] The utility model relates to the technical field of steel structure buildings, in particular to a square hole reinforcement structure of a steel beam web. Background Art

[0002] The steel columns and beams of steel structures can be prefabricated in factories and then assembled on site. The construction speed is fast and the construction period is short, which is especially suitable for the construction requirements of large venues and factories. For the steel beam structure in steel structure buildings, the upper side of the steel beam is subjected to compressive stress, and the lower side of the steel beam is subjected to tensile stress. The middle part of the web between the upper and lower side plates of the steel beam is subjected to small force. Therefore, I-beams are usually used for steel beams. The I-shaped web can be opened at the center line of the web to reduce the deadweight of the steel beam. However, it is found in practice that although the center line of the web of the steel beam is subjected to small force, the material around the web opening is still at risk of deformation and cracking, which is more obvious in the square hole structure at the web of the steel beam. Utility Model Content

[0003] The utility model aims to solve the problem of deformation and cracking risks at the square holes in the web of the existing I-shaped steel beam, and to provide a square hole reinforcement structure for the web of the steel beam, so as to structurally reinforce the square holes in the web of the steel beam with a larger load-bearing capacity to ensure structural safety and further enhance the bearing capacity of the steel beam.

[0004] The utility model adopts the following technical solution to solve the technical problem: a square hole reinforcement structure of a steel beam web, comprising a steel beam, at least one end of which is connected to a steel column, the steel beam being an I-beam, comprising an upper beam plate, a lower beam plate and a web, a plurality of square holes being opened in the middle of the web along the extension direction of the steel beam, horizontal reinforcement plates being arranged on the upper and lower sides of the square hole, first vertical reinforcement plates being arranged on the left and right sides of the square hole, ends of the horizontal reinforcement plates extending beyond ends of the first vertical reinforcement plates, and upper and lower ends of the first vertical reinforcement plates respectively abutting against and being welded and fixed to the upper and lower horizontal reinforcement plates.

[0005] The device sets a reinforcement plate around the side of the square hole to strengthen the circumference of the square hole to prevent deformation and cracking of the square hole when the steel beam is bearing weight, which affects the structural safety. At the same time, the structure of the horizontal reinforcement plate can help the steel beam improve its bearing capacity and ensure the structural safety.

[0006] Preferably, the horizontal reinforcement plate and the first vertical reinforcement plate are symmetrically arranged on both sides of the web.

[0007] Preferably, outer sides of the horizontal reinforcing plate and the first vertical reinforcing plate away from the web plate are flush with outer sides of the upper beam plate and the lower beam plate.

[0008] Preferably, the spacing between adjacent sides of adjacent square holes is not less than the length of the square holes.

[0009] Preferably, the spacing between adjacent sides of adjacent square holes is not less than the height of the steel beam.

[0010] Preferably, the length of the square hole is smaller than the height of the steel beam.

[0011] As another preferred solution, the length of the square hole is greater than the height of the steel beam, and a second vertical reinforcing plate is respectively arranged between the upper horizontal reinforcing plate of the square hole and the upper beam plate, and between the lower horizontal reinforcing plate of the square hole and the lower beam plate. The second vertical reinforcing plate is aligned with the first vertical reinforcing plate, and the upper and lower ends of the second vertical reinforcing plate are welded and fixed; the horizontal reinforcing plate, the first vertical reinforcing plate, and the second vertical reinforcing plate corresponding to each square hole are arranged in a tic-tac-toe shape. When the length of the square hole is greater than the height of the beam, the upper and lower ends of the vertical reinforcing plate abut against the upper beam plate and the lower beam plate, thereby improving the consistency of the upper and lower beam plates and avoiding the misalignment of the upper and lower beam plates.

[0012] Preferably, the second vertical reinforcing plates are symmetrically arranged on both sides of the web.

[0013] Preferably, the outer side edge of the second vertical reinforcement plate is flush with the outer side edge of the first vertical reinforcement plate.

[0014] The utility model has the following beneficial effects: reinforcing plates are arranged around the sides of the square holes to strengthen the circumference of the square holes, thereby preventing deformation and cracking of the square holes when the steel beams bear loads, which may affect the structural safety; at the same time, the structure of the horizontal reinforcing plates can help the steel beams improve their bearing capacity and ensure the structural safety.
