Sectional type prefabricated bent cap and counter-pull type construction method applied to bent cap
A sectional type prefabricated bent cap comprises a bearing platform, stand columns and bent cap prefabricated sections. The stand columns are vertically arranged on the bearing platform, the two stand columns which are oppositely arranged are arranged on the bearing platform, and bent cap prefabricated sections which are oppositely arranged are placed on the stand columns which are oppositely arranged. The bearing platform is further provided with oppositely-arranged temporary pull rods, and the oppositely-arranged temporary pull rods are located between the oppositely-arranged stand columns. Middle wet connection sections connected with each other are arranged between the oppositely-arranged bent cap prefabricated sections, and the middle wet connection sections are located between the oppositely-arranged temporary pull rods. Compared with the prior art, the temporary pull rod is arranged at the inner end of the bent cap prefabricated section, the inner end of the bent cap prefabricated section and the bearing platform are tensioned through the temporary pull rod, and therefore the bent cap prefabricated section is supported on the stand column without a support, and the construction method is suitable for construction of a large-cantilever large-tonnage small-pier-distance bent cap. And meanwhile, the temporary pull rods can be detached after the prefabricated sections of the bent cap are installed, cost is saved, and the prefabricated installation precision of the bent cap is improved.
一种分段式预制盖梁，包括承台、立柱和盖梁预制节段；所述立柱竖直设置于承台上，且承台上设有相对设置的两根立柱，相对设置的立柱上搁置有相对设置的盖梁预制节段；所述承台上还设有相对设置的临时拉杆，相对设置的临时拉杆位于相对设置的立柱之间；相对设置的盖梁预制节段之间设有相连接的中间湿接段，中间湿接段位于相对设置的临时拉杆之间；与现有技术相比，通过在盖梁预制节段内端部上设置临时拉杆，将盖梁预制节段内端部与承台之间通过临时拉杆进行拉紧，从而实现盖梁预制节段在立柱上的无支架支撑，适用于大悬臂大吨位小墩距盖梁的施工，同时临时拉杆在盖梁预制节段的安装完成后可拆除，节约成本，加快了盖梁的预制安装精度。
