Prestressed hollow slab anti-floating construction process and connecting piece thereof
The invention provides a prestressed hollow slab anti-floating construction process and a connecting piece thereof.The prestressed hollow slab anti-floating construction process comprises the following steps that S1, a foundation pit is excavated and a formwork is installed, S2, slab bottom steel bars and rib beam steel bars are bound, S3, prestressed tendons are laid, S4, a plurality of hollow slabs are arranged in gaps of rib beams, S5, every two adjacent hollow slabs are connected in a pulling mode through the connecting piece, and S5, the prestressed hollow slabs are arranged in the gaps of the rib beams. S7, longitudinal steel bars are laid at the positions of the hollow slabs, S8, concrete is poured into the installed hollow slabs, and S9, prestressed tendon tensioning is conducted on the area where the concrete is applied. The problems that in the prior art, in the anti-floating construction process of the hollow slabs, the construction efficiency is low, and the anti-floating effect of the hollow slabs is poor are solved.
本发明提供了一种预应力空心板抗浮施工工艺及其连接件，其包括以下步骤：S1基坑开挖并安装模板,S2绑扎板底钢筋与肋梁钢筋,S3铺放预应力筋,S4将若干空心板安置在肋梁的空隙中,S5通过连接件将相邻两个空心板拉结连接,S6将连接件与肋梁下铁连接,S7对空心板处铺设纵向钢筋,S8向安装好的空心板浇筑混凝土,S9对施作混凝土的区域进行预应力筋张拉，其解决了现有技术中存在的在对空心板的抗浮施工过程中，施工效率低，空心板抗浮效果差的问题。
