Multifunctional supporting equipment for bridge construction

WANG LIMIN

The invention discloses multifunctional supporting equipment for bridge construction. The equipment structurally comprises an air bag supporting structure, a communicating air rod, an auxiliary bracket and a bottom rod, the communicating air rod is arranged at the top of the bottom rod, the communicating air rod is perpendicularly welded with the bottom rod, the auxiliary bracket is mounted on theside surface of the communicating air rod, the air bag supporting structure is mounted at the top, away from the bottom rod, of the communicating air rod, the air bag supporting structure is composedof a top plate, a bag ring, a bottom plate, a valve and a communicating pipe, the top end of the communicating pipe is vertically fixed right in the middle of the bottom plate, the top plate is arranged around the bottom plate through the bag ring, the top plate and the bag ring are mechanically fixed, and the bag ring is of a folding tube structure, is upwards unfolded after being inflated, andcan increase the height of the top plate after being inflated. Through mutual cooperation of the top plate, the bag ring and the bottom plate, the vertical height of the top plate is uniformly and equidistantly ensured by adopting the inflation amount, and the flatness of a poured bridge floor or pier is ensured according to gas flow and the flatness of the top plate, so that the problem of unevenness is avoided.

本发明公开了一种多功能桥梁施工用支撑设备，其结构包括气囊支撑结构、连通气杆、辅助支架、底杆，底杆顶部设有连通气杆，连通气杆和底杆垂直焊接，连通气杆的侧面则安装有辅助支架，连通气杆远离底杆的顶部安装有气囊支撑结构，气囊支撑结构由顶板、囊环、底板、阀门、接通管组成，接通管顶端和底板正中间垂直固定，底板外围通过囊环设有顶板，顶板和囊环机械固定，囊环为折叠管结构，在充气后会向上展开，在充气后，囊环能够提升顶板的高度，本发明通过顶板、囊环、底板之间相互配合，不仅采用充气的多寡，来均匀等距地保证顶板的垂直高度，还根据气体流动和顶板的平整性，确保浇筑后的桥面或者桥墩的平整，不会发生凹凸不平的问题。
