Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building structure engineering, in particular to a beam web circular hole reinforcement structure. Background Art
[0002] High-rise buildings contain numerous equipment and piping systems (water supply and drainage, electrical, HVAC, fire protection, etc.). When these pipes cross beam grids, routing them at the bottom of the steel beams can significantly reduce the building's clear floor height, hindering full utilization of the structural space. To address this issue, a common approach is to create pre-set pipe holes in the steel beam webs. However, the presence of these holes reduces the effective cross-section of the component, thereby reducing its load-bearing capacity. Traditional methods for reinforcing openings, such as sleeve reinforcement, annular plate reinforcement, and stiffening ribs, all require welding the reinforcing material to the component. Even factory welding can inevitably introduce defects such as thermal deformation and weld cracks into the component itself. Welding also creates residual stress in the cross-section. These potential risks can even threaten the safety of the structure in serious cases. If reinforcement is required after opening the holes on-site, on-site welding is required, which is not only labor-intensive and time-consuming, but also poses challenges in ensuring accuracy and quality.
[0003] After holes are opened in the web of a steel beam, pipes will be passed through them. Sometimes, the circular holes are not passed through with pipes and the holes are idle. Since the existence of the holes will reduce the stability of the beam web structure, a beam web circular hole reinforcement structure is needed. The redundant circular holes can be internally supported to compensate for the loss of bearing capacity and stiffness of the beam web caused by the circular holes, thereby reinforcing the beam web. Utility Model Content
