Large-span bent cap composite supporting system and construction method
The invention provides a large-span bent cap composite supporting system and a construction method. The large-span bent cap composite supporting system is used for large-span bent cap construction. Comprising a core-penetrating steel bar device, an I-shaped steel beam system, a hoop, an inclined support and a steel wire rope. The hoops are arranged on the pier columns, the two sets of inclined supports are symmetrically arranged between the two adjacent pier columns in a splayed shape, and the two ends of each inclined support are connected with the corresponding hoop and the corresponding I-shaped steel beam respectively. The steel wire rope is used for connecting two adjacent pier columns. The construction method has the beneficial effects that by arranging the inclined supports, when concrete is poured on the bent cap, vertical loads are transmitted to the pier columns through the inclined supports, and downwarping deformation of the midspan part of the I-shaped steel beam is limited; the steel wire ropes are arranged between the pier columns, displacement of the pier columns under the horizontal load effect is limited, the structural design is simple, stress is scientific and reasonable, meanwhile, construction is convenient and fast, installation and disassembly are easy, turnover use can be achieved, the construction cost is low, the construction period can be effectively shortened, the construction efficiency is improved, and the whole construction method is safe and reliable.
本发明提供一种大跨度盖梁复合支撑体系及施工方法，用于大跨度盖梁施工。包括穿芯钢棒装置、工字钢梁体系、抱箍、斜支撑和钢丝绳。抱箍设置于墩柱，斜支撑为两组，呈八字形对称设置于相邻两个墩柱之间，其两端分别与抱箍和工字钢梁相连；钢丝绳用于连接相邻两个墩柱。本发明的有益效果是通过设置斜支撑，盖梁混凝土浇筑时，竖向荷载由斜撑传递给墩柱，限制了工字钢梁跨中部位下挠变形；通过在墩柱之间设置紧绷的钢丝绳，限制了墩柱在水平荷载作用下产生位移，结构设计简单、受力科学合理，同时施工便捷，易于安装和拆卸，可周转使用，施工成本低，可有效缩短施工周期，提高施工效率，整体施工方法安全可靠。
