Support-free prefabricated floor slab with brackets
The invention relates to a support-free prefabricated floor slab with brackets, and belongs to the field of building structural members. According to the scheme, the support-free prefabricated floor slab is composed of a prefabricated concrete floor slab and a plurality of steel brackets, wherein the plurality of steel brackets are locally embedded in the side wall of the floor slab in the span direction; the steel brackets are composed of vertical steel plates, horizontal steel plates and a plurality of shear resistant pieces; and the parts, which are embedded in the floor slab, of the vertical steel plates and the shear resistant pieces form a fishbone structure, and the bottoms of the parts, which extend out of the floor slab, of the vertical steel plates are connected with the horizontal steel plates. According to the support-free prefabricated floor slab, the steel brackets are arranged on both sides of the concrete prefabricated floor slab, the steel brackets are supported on structural beams or walls through the horizontal steel plates of the steel brackets in the construction process of the floor slab, and the connecting performance of the steel brackets and concrete is improved through the fishbone structure anchored in the floor slab, so that load in the construction stage and the dead weight of the floor slab are transmitted to structural members such as beams and walls through the steel brackets, and the purpose that the lower part of the prefabricated floor slab is free of supporting is achieved. No support needs to be arranged below the floor slab, so that the construction efficiency is improved, and the construction cost is reduced; and the members have the advantages of the simple structure, easiness in production and convenience in installation.
本申请涉及一种带牛腿的免支撑预制楼板，属于建筑结构构件领域，本申请的方案由预制混凝土楼板和若干局部嵌于楼板跨度方向侧壁内的钢牛腿组成；钢牛腿由竖向钢板、平置钢板、若干抗剪件组成；竖向钢板嵌于楼板内的部分与抗剪件构成鱼骨结构，竖向钢板伸出楼板的部分底部与平置钢板连接。本方案通过在混凝土预制楼板两侧设置钢结构牛腿，在楼板施工过程中通过钢牛腿的平置钢板支撑在结构梁或墙体上，锚固于楼板内的鱼骨结构增强了其与混凝土的连接性能，使施工阶段荷载及楼板自重通过钢牛腿传递到梁、墙等结构构件上，以达到预制楼板下免支撑的目的。因楼板下无需设支撑，提高了施工效率并降低了施工成本；且构件构造简单，易于生产，安装方便。
