UHPC prefabricated stair with built-in FRP grids and construction method of UHPC prefabricated stair
The invention discloses a UHPC prefabricated stair with built-in FRP grids and a construction method of the UHPC prefabricated stair, and relates to the technical field of prefabricated stairs and construction thereof. The UHPC prefabricated stair comprises two sets of vertical beams which are symmetrically arranged, stair beam building surface layers are arranged on the opposite faces of the two sets of vertical beams which are symmetrically arranged, stair beam lifting lugs are arranged on the side faces of the stair beam building surface layers, two sets of lifting lug pin keys are arranged on the upper end face of the stair beam lifting lugs side by side, and prefabricated ladder steps are erected on the stair beam lifting lugs through the two sets of lifting lug pin keys. By adopting a combined structure form of the FRP grids and the UHPC, a certain number of FRP grids are arranged in a pressed area, so that the anti-pressure capability of the pressed area is improved when the stair is loaded, the ultimate bearing capacity of the stair is further improved, the safe use of parts is ensured, the self weight of the parts is small, the requirement on equipment during later hoisting is low, the durability is good, a composite material has excellent corrosion resistance, the durability of the whole parts is improved, and the service life of the whole parts is prolonged.
本发明公开了内置FRP格栅的UHPC预制楼梯及其施工方法，涉及预制楼梯及其施工技术领域，包括对称设置的两组竖向梁，对称设置的两组所述竖向梁相对面均设置有梯梁建筑面层，所述梯梁建筑面层的侧面设置有梯梁挑耳，所述梯梁挑耳的上端面并列设置有两组挑耳销键，所述梯梁挑耳上通过两组挑耳销键架设有预制梯阶；本发明通过采用FRP格栅与超高性能混凝土(UHPC)组合结构形式，通过在受压区布置一定数量的FRP格栅，以提高楼梯承载时受压区的抗压能力，进而提高楼梯的极限承载力，保证构件安全使用，且其自重小，后期吊装时对设备要求较低，具有良好的耐久性，复材具有优异的抗腐蚀性能，提高整个构件的耐久性和使用寿命。
