Support-free concrete laminated slab with pulley arching type structure
The invention provides a support-free concrete laminated slab with a pulley arching type structure. Comprising a prefabricated bottom plate (1), a conical support (5), a bolt (8) and a pulley assembly. The pulley assembly is of a triangular structure and is composed of a fixed pulley (5-3), a movable pulley track (6), two movable pulleys (6-2) and a steel wire rope (7). Wherein the fixed pulley (5-3) is fixed at the bottom end of the conical support (5) and connected with the movable pulley (6-2) through a steel wire rope (7), and the movable pulley track (6) is connected with the bottom of the prefabricated bottom plate (1) through a bolt (8). The pulley assembly is additionally arranged, the prefabricated bottom plate has the upward arching tendency by adjusting the position of a movable pulley in the movable pulley track, and the bending rigidity and the bending resistance of the prefabricated bottom plate are improved; therefore, no temporary support needs to be arranged during construction, the construction space is increased, and the construction difficulty and complexity are reduced.
本发明提供了一种带滑轮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(8)和滑轮组件；所述滑轮组件呈三角形结构，由一个定滑轮(5‑3)、动滑轮轨道(6)、两个动滑轮(6‑2)和钢丝绳(7)组成；其中，定滑轮(5‑3)固定在锥形支座(5)底端，并且与动滑轮(6‑2)由钢丝绳(7)连接，动滑轮轨道(6)通过螺栓(8)与预制底板(1)底部连接。本发明加设滑轮组件，通过调节动滑轮轨道中动滑轮的位置，使预制底板具有向上起拱的趋势，增加预制底板的抗弯刚度和抗弯性能；从而在施工时无须设置临时支撑，增加其施工空间，降低施工的难度和复杂性。
