Novel viaduct approach bridge prefabricated component
The invention discloses a novel viaduct approach bridge prefabricated component which comprises a concrete pipe pile. A bearing platform is poured at the top end of the concrete pipe pile, an n-shapedsupporting beam is poured in the middle of the top end of the bearing platform, precast concrete box girders are installed at the top end of the n-shaped supporting beam, and positioning bolts are arranged at the two sides of the top end of the n-shaped supporting beam at equal intervals; and positioning nuts are mounted on the outer surfaces of the positioning bolts in a threaded meshing manner,positioning clamping grooves are formed in the positions, close to the positioning bolts, of the two sides of the middle of the top end of the n-shaped supporting beam correspondingly, and positioning screw grooves are formed in the two sides of the bottom end of the inner wall of each positioning clamping groove correspondingly. According to the novel viaduct approach bridge prefabricated component, by using I-shaped connecting plates, connecting clamping blocks and fixing plates, two adjacent precast concrete box girders can be connected, the connecting and assembling difficulty between thetwo adjacent precast concrete box girders can be reduced, the precast concrete box girders can be conveniently and quickly assembled and used, and the construction efficiency of workers can be improved.
本发明公开一种新型高架桥引桥预制构配件，包括混凝土管桩，所述混凝土管桩顶端浇注有承台，所述承台顶端中部浇注有冂型支撑梁，所述冂型支撑梁顶端安装有预制混凝土箱梁，所述冂型支撑梁顶端两侧均等距设置有定位螺栓，所述定位螺栓外表面螺纹啮合安装有定位螺帽，所述冂型支撑梁顶端中部两侧靠近定位螺栓处均开设有定位卡槽，所述定位卡槽内壁底端两侧均开设有定位螺槽。本发明通过工型连接板、连接卡块和固定板的使用，可以对两个相邻预制混凝土箱梁进行连接，可以降低两个相邻预制混凝土箱梁之间的连接组装难度，便于预制混凝土箱梁的快速拼装使用，有利于提高工作人员的施工效率。
