Prefabricated hollow slab and construction method thereof
The invention provides a prefabricated hollow slab and a construction method thereof. The prefabricated hollow slab comprises a slab body, a steel bar support, a first row of steel strands, a first row of PVC pipes, a second row of steel strands, a second row of PVC pipes and a third row of steel strands; the steel bar support comprises a plurality of transverse bars and a plurality of longitudinal bars, the extending direction of the transverse bars is consistent with the width direction of the slab body, the extending direction of the longitudinal bars is consistent with the thickness direction of the slab body, and the transverse bars and the longitudinal bars are fixedly connected to form a grid structure; the first row of steel strands, the first row of PVC pipes, the second row of steel strands, the second row of PVC pipes and the third row of steel strands are inserted into the grid structure and fixedly connected with the steel bar support. According to the prefabricated hollow slab and the construction method thereof, the PVC pipe is adopted to realize retention of a hollow slab hole, and the steel bar support is utilized to realize high-precision positioning of the PVC pipe, so that the flatness and linearity of the hollow slab hole are ensured, the construction quality can be ensured, the construction efficiency can be improved, and the construction cost can be reduced.
本发明提供了一种预制空心板及其施工方法，其中，预制空心板包括：板体、钢筋支架、第一排钢绞线、第一排PVC管、第二排钢绞线、第二排PVC管和第三排钢绞线；钢筋支架包括多条横筋和多条纵筋，多条横筋的延伸方向均与板体的宽度方向一致，多条纵筋的延伸方向均与板体的厚度方向一致，多条横筋与多条纵筋固定连接形成网格结构；第一排钢绞线、第一排PVC管、第二排钢绞线、第二排PVC管和第三排钢绞线分别插设于网格结构中并与钢筋支架固定连接。在本申请提供的预制空心板及其施工方法中，采用PVC管实现空心板孔洞的留置，并利用钢筋支架实现PVC管的高精度定位，由此确保空心板孔洞的平整度及直线性，既能确保施工质量，又能提高施工效率，降低施工成本。
