Large-span prestress bent cap support
The invention discloses a large-span prestress bent cap support which comprises an embedded steel plate and a bearing bottom beam. The embedded steel plates are fixed through foundation bolts and are horizontally embedded under a roadbed, steel stand columns perpendicular to the embedded steel plates are arranged on the embedded steel plates, and the number of the embedded steel plates is at least two. The bearing bottom beams are symmetrically erected between the tops of the two steel stand columns, a plurality of supporting columns arranged in the vertical direction are arranged on the bearing bottom beams, and bearing top beams are fixedly arranged on the tops of the supporting columns; an inclined supporting rod is arranged between every two adjacent supporting columns, the two ends of each supporting rod are arranged at the ends of the corresponding supporting columns respectively, and buffer columns connected with the supporting rods are arranged on the bearing bottom beam and used for dispersing stress of the supporting rods. The buffer columns are arranged and matched with the supporting rods to disperse pressure borne by the bearing top beam in the capping beam pouring and building process, the bending strength of the bearing top beam when the bearing top beam bears the pressure is improved, the levelness of the capping beam in the pouring and building process is guaranteed, and repeated utilization of the capping beam support is facilitated.
本发明公开了一种大跨径预应力盖梁支架，包括：预埋钢板、承重底梁；预埋钢板通过地脚螺栓固定且水平埋设于路基之下，预埋钢板上设有与其相垂直的钢立柱，预埋钢板至少对称设有两个；承重底梁对称架设于两个钢立柱顶部之间，承重底梁上设有多个沿竖直方向设置的支柱，支柱顶部固设有承重顶梁；相邻支柱之间设有倾斜设置的撑杆，撑杆的两端分别设于支柱的端部，承重底梁上设有与撑杆连接的缓冲柱，缓冲柱用于分散撑杆受力；本发明通过缓冲柱的设置，配合撑杆对承重顶梁在盖梁浇筑建造过程中所受压力进行分散，提高其承受压力时的抗弯强度，保证盖梁浇筑建造时的水平度，也有利于盖梁支架的重复利用。
