Prestressed laminated wood T-beam bridge and construction method thereof
The invention provides a prestressed laminated wood T-beam bridge and a construction method thereof.The prestressed laminated wood T-beam bridge comprises two or more laminated wood T-beams which are assembled and connected, each laminated wood T-beam comprises a web, a flange plate and a horseshoe part, the top of each web is fixedly connected with the corresponding flange plate, and the bottom end of each web is fixedly connected with the corresponding horseshoe part; a plurality of transverse prestress holes are formed in the top of the laminated wood T-shaped beam in a penetrating mode, a plurality of longitudinal prestress holes are formed in the middle of the horseshoe part in a penetrating mode, and flange plate connecting holes are formed in the connecting parts of the flange plates. The two flange plates of every two adjacent laminated wood T beams are connected through I-shaped steel and first bolts. A transverse partition plate is assembled between two web plates of every two adjacent laminated wood T beams; a transverse prestress anchoring system is arranged between the two or more laminated wood T beams; the horseshoe part is provided with a longitudinal prestress anchoring system in the length direction. The strength, rigidity and toughness of a modern wood structure bridge are improved, and therefore the use safety and durability of the bridge are improved.
本发明提供了一种预应力胶合木T梁桥及其施工方法，预应力胶合木T梁桥包括装配连接的两片或多片胶合木T梁，胶合木T梁包括腹板、翼缘板和马蹄部，腹板的顶部固定连接有翼缘板，腹板的底端固定连接有马蹄部；胶合木T梁的顶部穿设有若干个横向预应力孔，马蹄部的中部穿设有若干个纵向预应力孔，翼缘板的连接部开设有翼缘板连接孔；相邻两片胶合木T梁的两个翼缘板之间通过工字钢和第一螺栓进行连接；相邻两片胶合木T梁的两个腹板之间装配有横隔板；两片或多片胶合木T梁之间设有横向预应力锚固系统；马蹄部沿其长度方向设有纵向预应力锚固系统。本发明提高了现代木结构桥梁的强度、刚度以及韧性，从而提高了其使用安全性和耐久性。
