Cold-bent cap type steel combined section column-double corrugated steel plate combined shear wall with PBL shear keys

YU JINGUANG / ZHAO CHU / ZHONG WEIHUI

The invention discloses a cold-bending cap type steel combined section column-double corrugated steel plate combined shear wall with PBL shear keys, and the cold-bending cap type steel combined section column-double corrugated steel plate combined shear wall is characterized in that first cold-bending cap type steel and second cold-bending cap type steel are arranged at the end part of a first corrugated steel plate and the end part of a second corrugated steel plate, one end of the first cold-bent cap-shaped steel is connected with one end of the second cold-bent cap-shaped steel through a bolt, and the PBL shear key sequentially penetrates through the other end of the first cold-bent cap-shaped steel, the end of the first corrugated steel plate, the end of the second corrugated steel plate and the second cold-bent cap-shaped steel. The first UHPC non-dismantling formwork is fixed to the wave crest position of the first corrugated steel plate and the first cold-bent cap profile steel, the second UHPC non-dismantling formwork is fixed to the wave trough position of the second corrugated steel plate and the second cold-bent cap profile steel, and the area defined by the first cold-bent cap profile steel and the second cold-bent cap profile steel is filled with first lightweight concrete. The shear wall has excellent lateral resistance, and meanwhile, a cavity effect is not easy to form.

本发明公开了一种带PBL剪力键的冷弯帽型钢组合截面柱‑双波纹钢板组合剪力墙，第一波形钢板的端部及第二波形钢板的端部设置有第一冷弯帽型钢及第二冷弯帽型钢，其中，第一冷弯帽型钢的一端与第二冷弯帽型钢的一端通过螺栓相连接，PBL剪力键依次穿过第一冷弯帽型钢的另一端、第一波形钢板的端部、第二波形钢板的端部及第二冷弯帽型钢，第一块UHPC免拆模板固定于第一波形钢板的波峰位置处以及第一冷弯帽型钢上，第二块UHPC免拆模板固定于第二波形钢板的波谷位置处以及第二冷弯帽型钢上，第一冷弯帽型钢与第二冷弯帽型钢围成的区域内填充有第一轻质混凝土，该剪力墙具有优异的抗侧性能，同时不易形成空腔效应。
