Fabricated concrete grouting connection stair and construction method
The invention relates to the technical field of constructional engineering, and particularly discloses a fabricated concrete grouting connection stair and a construction method. The fabricated concrete grouting connection staircase comprises a main staircase plate, an auxiliary staircase plate, a top staircase beam, a bottom staircase beam and a bottom sliding support which are all formed in a one-time pouring mode. The top ladder beam is of a ladder-shaped structure and comprises a first horizontal plane and a second horizontal plane, and the second horizontal plane is provided with a connecting piece connected with the main ladder plate and the auxiliary ladder plate. Preformed holes matched with the connecting pieces are formed in the top ends of the main ladder plate and the auxiliary ladder plate, the connecting pieces penetrate through the preformed holes and are fixed through grouting, the two sides of each preformed hole are connected with an air inlet and an air outlet, and the bottoms of the main ladder plate and the auxiliary ladder plate are connected with the bottom ladder beam through bottom sliding supports; the main ladder plate and the auxiliary ladder plate are detachably connected into a whole, and the joint of the two is coated with a building sealant. A mounting mode of the main stair plates and the auxiliary stair plates is adopted, the single-time hoisting weight of the assembly type stair is reduced, and meanwhile the problems that a traditional segmented stair is not high in integrity, and the joint face cracks are solved through a grouting connection mode.
本发明涉及建筑工程技术领域，具体公开了一种装配式混凝土灌浆连接楼梯及施工方法；装配式混凝土灌浆连接楼梯包括主梯板、副梯板、顶部梯梁、底部梯梁和底部滑动支座，均采用一次浇筑成型；顶部梯梁为阶梯状结构，包括第一水平面和第二水平面，第二水平面设有与主副梯板连接的连接件；主梯板和副梯板顶端设有与连接件相匹配的预留孔，连接件穿入预留孔并灌浆固定，预留孔两侧连接进气孔与出气孔，主副梯板底部均通过底部滑动支座与底部梯梁连接；主梯板与副梯板之间可拆卸连接为一体，二者结合处涂建筑密封胶。采用主梯板、副梯板安装模式，减轻了装配式楼梯单次吊装重量，同时灌浆连接方式解决了传统分段楼梯整体性不强，结合面开裂等问题。
