Hollow slab assembly type prefabricated stair and preparation method
The invention discloses a hollow slab assembly type prefabricated stair and a preparation method, and the hollow slab assembly type prefabricated stair comprises an upper floor slab and a lower floor slab, the upper floor slab and the lower floor slab are connected through a bottom plate with inclination, a plurality of steps are arranged on the bottom plate, and cavities are formed in the upper floor slab, the lower floor slab and the steps; bottom plates of the upper floor slab and the lower floor slab are made of C30 concrete, the middle step is made of foam concrete, the foam concrete hollow slab prefabricated staircase is optimized under certain load and constraint conditions by utilizing a topological optimization technology under the condition that the surface integrity of the staircase is kept, the usage amount of materials and the self weight of the structure are greatly reduced, and the construction cost is reduced. Moreover, the stair treads are made of foam concrete, the weight of the stair is further reduced, the overall dead weight of the stair can be greatly reduced by adopting the foam concrete hollow slab to prefabricate the stair, and the stair is convenient to manufacture, transport, install and the like.
本发明公开了空心板装配式预制楼梯及制备方法，本发明属于属于空心板装配式预制楼梯,包括上楼板和下楼板，上楼板和下楼板之间通过带有斜度的底板相连，底板上设置有多个踏步，上楼板和下楼板以及踏步上均设置有空腔，上楼板和下楼板的底板采用C30混凝土，中间踏步采用泡沫混凝土，本发明中，泡沫混凝土空心板预制楼梯在一定负载和约束条件下，利用拓扑优化技术，在保留楼梯表面完整度的情况下，对其进行优化，大量减少了材料的使用量以及结构自重，而且对于楼梯踏板采用泡沫混凝土，进一步对楼梯重量进行降低，采用泡沫混凝土空心板预制楼梯可以大幅度降低楼梯整体自重、方便楼梯的制作、运输及安装等工作。
