Section steel straining beam suitable for large-span column-free arch-shaped structure
The invention discloses a profile steel straining beam suitable for a large-span column-free arch-shaped structure, and relates to the field of underground structures, the profile steel straining beam comprises an underground arch-shaped structure, and the underground arch-shaped structure comprises a side wall and an arch-shaped top plate connected to the top of the side wall; the profile steel beam is located at an arch foot of the top plate, and the two ends of the profile steel beam are fixedly connected with the side walls on the two opposite sides respectively; the section steel beam is partially located in the top plate, and the part, located in the top plate, of the section steel beam is provided with a plurality of shear-resistant studs. The invention provides a profile steel straining beam suitable for a large-span column-free arch-shaped structure so as to solve the problem that in the prior art, an underground large-span column-free arch-shaped structure is limited during expansion and reconstruction. The purposes of improving the stability and the bearing capacity of the underground large-span column-free arch structure in the construction period or long-term expansion and reconstruction use and reducing the structure instability risk are achieved.
本发明公开了一种适用于大跨无柱拱型结构的型钢拉梁，涉及地下结构物领域，包括地下拱形结构，所述地下拱形结构包括侧墙、连接在侧墙顶部的拱形的顶板；还包括位于所述顶板的拱脚处的型钢梁，所述型钢梁的两端分别与相对两侧的侧墙固定连接；所述型钢梁局部位于所述顶板内，且型钢梁位于顶板内的部分设置若干抗剪栓钉。本发明提供一种适用于大跨无柱拱型结构的型钢拉梁，以解决现有技术中的地下大跨无柱拱型结构在扩展与改建时受限的问题，实现提升地下大跨无柱拱型结构在施工期间或长期扩展改建使用中的稳定性和承载能力、降低结构失稳风险的目的。
