Lightweight assembly type prefabricated floor slab and manufacturing method thereof
The invention discloses a lightweight assembly type prefabricated floor slab which is characterized by comprising a fine aggregate concrete bottom plate, alkali-resistant glass fiber gridding cloth, a ribbed expansion net, lower chord longitudinal steel bars in a formed steel bar truss structure, upper chord longitudinal steel bars and web member wave-shaped steel bars with bent feet. The lightweight assembly type prefabricated floor slab is light in weight which is about 1/4 of the weight of a laminated slab; the lightweight assembly type prefabricated floor slab has large longitudinal rigidity, and the large-span support-free effect of 2 meters or more can be achieved in the construction period; and the bottom of the fine aggregate concrete bottom plate can be directly subjected to puttying decoration. According to the lightweight assembly type prefabricated floor slab, the fine aggregate concrete bottom plate is used for replacing a traditional wood formwork, the size of the bottom formwork is customized, loss, waste and solid waste emission are avoided, and the green and environment-friendly concept is met. According to the lightweight assembly type prefabricated floor slab, a fine aggregate concrete cast-in-place mode is adopted, formed steel bars and ribbed expansion nets are poured into a whole, one-time forming is achieved, the labor cost of later-period secondary assembly is saved, and the lightweight assembly type prefabricated floor slab is more economical and reasonable. According to the lightweight assembly type prefabricated floor slab, the rigidity, the strength, the toughness and the anti-cracking effect of the fine aggregate concrete bottom plate are enhanced through the ribbed expansion net, the fine aggregate concrete bottom plate and the forming steel bars on the upper portion can be welded into a whole, and the ribbed expansion net plays a double role in connecting a previous part and a next part.
本发明公开了一种轻量化装配式预制楼板，其特征在于：包括细石混凝土底板、耐碱玻璃纤维网格布、有筋扩张网、成型钢筋桁架结构中的下弦纵向钢筋、上弦纵向钢筋、腹杆波浪型带弯脚钢筋组合所构成；这种轻量化装配式预制楼板重量轻，约为叠合板重量的1/4；它还有较大的纵向刚度，在施工期间也可以做到2米以上大跨度无支撑；它的细石混凝土底板底部可以直接刮腻子装修；这种轻量化装配式预制楼板，用细石混凝土底板替代传统木模板，底模定制尺寸，无损耗，无浪费，无固体费弃物排放，符合绿色环保理念；这种轻量化装配式预制楼板，用细石混凝土现浇的方式，把成型钢筋与有筋扩张网浇筑成整体，一次成型，节约了后期二次组装的人工成本，更经济合理；这种轻量化装配式预制楼板，使用了有筋扩张网增强了细石混凝土底板的刚度、强度、韧性和抗裂作用，又能与上部的成型钢筋焊接成整体，有筋扩张网起到承上启下一举两得的双重作用。
