Support-free concrete laminated slab of arching type structure
The invention provides a support-free concrete laminated slab of an arching type structure. Comprising a prefabricated bottom plate (1), a conical support (5), a bolt (7) and a steel wire rope (6). A fixed pulley (5-3) is arranged at the bottom of the conical support (5), and the two bolts (7) and the fixed pulley (5-3) are connected through a steel wire rope (6) and arranged in a triangular mode. The two bolts (7) are fixedly installed on the prefabricated bottom plate (1), and the top of the conical support (5) is connected with the bottom face of the prefabricated bottom plate (1) through the bolts (7). According to the support-free concrete laminated slab of the arching type structure, the laminated slab has the upward arching trend by adjusting the bolts at the two ends of the steel wire rope, the construction load borne by the laminated slab is resisted, and the rigidity and the bending resistance of the laminated slab are improved. Namely, a temporary support does not need to be arranged during construction, so that the construction efficiency is improved, and the construction difficulty and complexity are reduced.
本发明提供了一种起拱式结构的免支撑混凝土叠合板；包括预制底板(1)、锥形支座(5)、螺栓(7)、钢丝绳(6)；锥形支座(5)的底部设置有定滑轮(5‑3)，两个螺栓(7)和定滑轮(5‑3)由钢丝绳(6)连接，且呈三角形排布；所述两个螺栓(7)固定安装在预制底板(1)上，锥形支座(5)的顶部通过螺栓(7)与所述预制底板(1)的底面连接。本发明所涉及的起拱式结构的免支撑混凝土叠合板通过调节钢丝绳两端螺栓，使叠合板具有向上起拱的趋势，抵抗其所承受的施工荷载，提高叠合板的刚度和抗弯性能。即在施工时不须设置临时支撑，从而提高施工效率和降低施工的难度和复杂性。
