High-performance concrete-recombination bamboo prefabricated T beam composite structure and construction method
The invention discloses a high-performance concrete-recombined bamboo prefabricated T-beam composite structure and a construction method, the high-performance concrete-recombined bamboo prefabricated T-beam composite structure comprises a prefabricated T-beam and a connecting structure, the prefabricated T-beam comprises a high-performance concrete flange and a recombined bamboo web, the top of the recombined bamboo web is provided with a wedge-shaped recombined bamboo bulge, and a transverse anchoring steel bar penetrates through the wedge-shaped recombined bamboo bulge; longitudinal steel bars are arranged at the bottoms in the recombined bamboo webs, the prefabricated T-shaped beams can be independently used, when the span number of a bridge is large, a plurality of prefabricated T-shaped beams can be longitudinally combined for use to form a combined beam, the two prefabricated T-shaped beams are longitudinally connected and fixed through a connecting structure, and the connecting structure comprises U-shaped stiffening steel clamping plates and clamping plate bolts. Closed stirrups are welded to the middles of the U-shaped stiffening steel clamping plates, and bent steel bars are embedded in the high-performance concrete flanges. The recombined bamboo and the high-performance concrete are combined, the durability and the crack resistance of the structure are improved, the structure can be suitable for a simply supported beam and can also form a continuous beam, the stress state of the beam is further improved, and materials are saved.
本发明公开了一种高性能混凝土‑重组竹预制T梁组合结构及施工方法，包括预制T形梁和连接结构，预制T形梁包括高性能混凝土翼缘和重组竹腹板，重组竹腹板顶部设有楔形重组竹凸起，楔形重组竹凸起内贯穿有横向锚固钢筋，重组竹腹板内底部设置有纵向钢筋，预制T形梁可单独使用，且当桥梁跨数较多时预制T形梁也可纵向多个组合使用形成组合梁，两个预制T形梁纵向通过连接结构连接固定，连接结构包括U形加劲钢夹板和夹板螺栓，U形加劲钢夹板中部焊有闭口箍筋，高性能混凝土翼缘内部预埋有弯起钢筋。本发明将重组竹与高性能混凝土结合，提高了结构的耐久性、抗裂性能，可适用于简支梁，也可构成连续梁，从而进一步改善梁的受力状态，节省材料。
