Steel tower cable-stayed bracket for large cantilever bent cap
The invention discloses a steel tower cable-stayed bracket for a large cantilever bent cap. The steel tower cable-stayed compartment comprises a floor stand, a main beam, a tower, a triangular truss,a fixed supporting table, a cable-stayed part, a sand cylinder and a parallel connection part. According to the steel tower cable-stayed bracket for the large cantilever bent cap, the girder structureis formed by fixedly connecting the girder composed of the I-shaped steel and the distribution beam through the multiple sand cylinders, the tower cable-stayed bracket is modularly disassembled and assembled and can be rapidly disassembled, assembled and recycled through detachable connection of all the components, and support material waste is avoided. The assembling and disassembling rates of the bracket are increased greatly. In addition, the structure that the bottom of the bent cap is in a broken line shape and changes along with the gradient of the bridge deck is achieved through the triangular truss structure of the tower cable-stayed bracket, the tower cable-stayed bracket meets the load requirement during mass concrete pouring, a hanging belt can be tensioned on the tower top, and then the deflection of the cantilever end of the bracket is adjusted; and the final linearity and elevation of the bent cap are consistent with those of the design.
本发明公开了一种用于大悬臂盖梁的钢塔斜拉支架，包括落地支架、主梁、塔架、三角桁架、固定支撑台、斜拉件、砂筒和平联。该用于大悬臂盖梁的钢塔斜拉支架，通过工钢组成的主梁与分配梁之间通过若干个砂筒固定连接，形成大梁结构，利用各个部件之间的可拆卸式连接，让塔架斜拉支架实现了模块化拆装，可快速拆装周转使用，避免了支架材料浪费，大大加快了支架的搭拆速率，另外通过塔架斜拉支架的三角桁架结构实现了盖梁底部为折线形，且随桥面坡度变化的结构，该塔架斜拉支架满足了大体积混凝土浇筑时的荷载要求，且可在塔顶张拉吊带进而调整支架悬臂端挠度，保证盖梁最终线形及标高与设计一致。
