Prefabricated mounting bridge abutment
The invention relates to the technical field of building construction, in particular to a prefabricated installation bridge abutment which comprises a formwork, a pier column and an installation rod. An original cast-in-place bridge abutment is optimized into a prefabricated bridge abutment, specifically, a half-range bridge abutment is formed, a back wall and a second wall are prefabricated into two blocks, the position of a pipe pile and the top face elevation are strictly controlled during pile foundation implanting construction, pile heads penetrate into reserved holes of the bridge abutment by 6 cm, reserved grooves are formed in other components, gaps are compacted through high-strength shrinkage-free grouting materials, and the construction efficiency is greatly improved. The back wall and the ear wall are connected through embedded steel bars, a small amount of concrete is poured to achieve construction of the whole bridge abutment, and the construction efficiency is higher; the fixing bolts are inserted into the first connecting piece and the second connecting piece to be fixed, so that the device is clamped on a prefabricated bridge abutment, a rope of a lifting hook sequentially penetrates through the fixing holes to be connected, structural pieces are fixed to assemble needed parts, local materials are used, steel pipes are bent to be made, practicability is good, and the clamping blocks move in an arc shape with the rotating shaft as the center point; and the clamping blocks are clamped on the inner walls of the fixing grooves, and the fixing effect is achieved.
本发明涉及建筑施工技术领域，具体为一种预制安装桥台，包括模板、墩柱和安装杆；本发明通过本来现浇桥台优化为预制桥台，具体为半幅的桥台、背墙、二墙预制成2块，在植入桩基施工时严格控制管桩位置及顶面高程，桩头深入桥台预留洞口6cm，其他构件设置预留槽，缝隙用高强无收缩灌浆料密实，背墙与耳墙通过预埋钢筋将二者连接浇筑少量混凝土实现整个桥台施工，施工效率更快；通过将固定插销插入到第一连接件和第二连接件固定，使得装置卡在预制桥台上，将起吊钩子的绳依次穿过固定孔连接，固定结构件组装所需要的零件，就地取材使用钢管弯曲制成，实用性好，夹紧块以转轴为中心点成弧形运动，使得夹紧块夹紧在固定槽的内壁上，起到固定效果。
