Profile steel stiffening corrugated steel-concrete combined arch shell structure
The invention provides a profile steel stiffening corrugated steel-concrete combined arch shell structure, and belongs to the technical field of arch shell structures. An existing corrugated steel-concrete combined arch shell needs to be welded with studs to serve as shear connectors, reinforcing steel bars are arranged on the upper portion to resist hogging moment, construction is troublesome, the assembly degree is low, and the workload of binding the reinforcing steel bars on site is large. The structure comprises two layers of corrugated steel arch plates and a concrete structure between the two layers of corrugated steel arch plates, each layer of corrugated steel arch plate comprises a plurality of corrugated steel arch plate units with the edges overlapped by 1/2-1 waveform, profile steel is arranged on the upper end face of the upper layer of corrugated steel arch plate, and distributed reinforcing steel bars sequentially penetrate through distributed reinforcing steel bar reserved holes in a plurality of profile steel on the same horizontal plane and are perpendicular to the profile steel. The profile steel is used as a connecting piece and an anti-hogging moment steel bar at the same time, and the overall stability of the arch shell structure is improved; the construction site assembly speed is high, connection is convenient, and rapid assembly can be achieved; the profile steel serves as a connecting piece, the pulling resistance is higher than that of studs, and the lifting resistance of the profile steel is 1.5-2.5 times that of a common arch shell structure.
本发明提供一种型钢加劲波纹钢‑混凝土组合拱壳结构，属于拱壳结构技术领域。现有波纹钢－混凝土组合拱壳需要焊接栓钉作为抗剪连接件，为抵抗负弯矩而在上部配置钢筋，施工麻烦，装配化程度低，现场绑扎钢筋工作量大。本发明包括两层波纹钢拱板和之间的混凝土结构，每层波纹钢拱板包括若干个边缘处重叠1/2‑1个波形的波纹钢拱板单元，上层波纹钢拱板上端面设置有型钢，分布钢筋依次贯穿同一水平面的多个型钢上的分布钢筋预留孔且与型钢垂直。将型钢同时作为连接件和抗负弯矩钢筋，提高拱壳结构整体稳固性；施工现场装配速度快，连接方便，可实现快速装配；型钢作为连接件，比栓钉抗拔能力强，是普通拱壳结构抗掀起性能的1.5‑2.5倍。
