Steel beam web plate rectangular hole reinforcing structure reinforced by profile steel
The invention discloses a steel beam web plate rectangular hole reinforcing structure reinforced by profile steel. The steel beam is mainly composed of an upper flange, a lower flange and a web plate, the web plate is connected between the upper flange and the lower flange, a rectangular hole is formed in the middle of the web plate, a reinforcing unit is arranged at the rectangular hole of the web plate, and the two pieces of vertical angle steel are symmetrically arranged on the left side and the right side of the rectangular hole respectively. The two pieces of horizontal angle steel are symmetrically arranged on the upper side and the lower side of the rectangular hole respectively, the vertical angle steel and the horizontal angle steel are welded to form a square-shaped extending structure in a surrounding mode, and the vertical angle steel/the horizontal angle steel is connected through steel beam webs in a welding seam or bolt or bolt-welding mixed mode. Through the square-shaped extension structure formed by the vertical angle steel and the horizontal angle steel, the bending resistance and the shearing resistance of the web perforated beam section can be effectively improved, and the welding residual stress and deformation of the web are reduced; and factory prefabrication can be achieved, the welding workload can be greatly reduced, construction is easy and rapid, and performance is excellent.
本发明公开了一种采用型钢加强的钢梁腹板开矩形孔补强构造。钢梁主要由上翼缘、下翼缘和腹板组成，腹板连接在上翼缘和下翼缘之间，腹板的中部开设有矩形孔洞，在腹板的矩形孔洞处设有补强单元，两个竖向角钢分别对称设置在矩形孔洞的左右两侧，两个水平角钢分别对称设置在矩形孔洞的上下两侧，竖向角钢和水平角钢焊接后围成“口”字形延伸结构，竖向角钢/水平角钢采用焊缝、螺栓或栓焊混合的方式钢梁腹板连接。本发明通过竖向角钢和水平角钢组成的“口”字形延伸结构，可以有效提高腹板开孔梁段的抗弯和抗剪承载力，减小腹板的焊接残余应力和变形；可实现工厂预制，可大大减少焊接工作量，施工简单、快速，性能优越。
