Tool type truss supporting system for multi-layer basement settlement post-cast strip and construction method of tool type truss supporting system
The invention provides a tool type truss supporting system for a multi-layer basement settlement post-cast strip and a construction method of the tool type truss supporting system. The tops of the supporting concrete columns are fixedly connected with the tool type steel truss to form a pre-reinforcing system, guarantee is provided for passing of heavy vehicles, and the reinforcing system and the same-layer concrete vertical and horizontal structures are poured together. The temporary supporting concrete columns are fixedly connected with the main body structure foundation to form a stable temporary supporting system; the tool type steel trusses are arranged on the lower portions of floor slabs on the two sides of the settlement post-cast strip, are close to the floor slabs on the two sides of the settlement post-cast strip and are pre-arched at the same time. Construction loads on the upper portion of the heavy vehicle passing road are sequentially transmitted to the floor slabs on the two sides of the settlement post-cast strip, the tool type steel trusses and the temporary supporting concrete columns and transmitted to the main body structure foundation layer by layer. On the premise of meeting the temporary supporting effect of the post-cast strip, heavy vehicles can pass through the upper portion of the post-cast strip, meanwhile, the influence on a main body structure is reduced, safety and reliability are achieved, and the construction period is guaranteed.
本发明提供一种多层地下室沉降后浇带工具式桁架支撑体系及其施工方法。支撑混凝土柱的顶部与工具式钢桁架固定连接形成预加固体系，为重型车辆的通行提供保障，该加固体系与同层混凝土竖向和水平结构一起浇筑；临时支撑混凝土柱与主体结构基础固定连接，形成稳定的临时支撑体系；所述工具式钢桁架设置在沉降后浇带两侧的楼板下部，与沉降后浇带两侧的楼板贴近，并同时预起拱；重型车辆通行道路上部施工荷载依次传至沉降后浇带两侧的楼板、工具式钢桁架、临时支撑混凝土柱，逐层传送至主体结构基础。本发明在满足后浇带临时支撑的作用的前提下，后浇带上部可以通行重型车辆，同时减少了对主体结构的影响，安全可靠，保证工期。
