Prestressed hollow slab construction process
The invention is applicable to the technical field of building prestressed hollow slabs, and provides a prestressed hollow slab construction process which comprises the following steps: firstly, manufacturing prestressed tendons and storing the prestressed tendons; a plate bottom die and an end die are supported, lofting is conducted on the plate bottom die and the end die, and plate bottom ribs and ribbed beam steel bars are bound; laying prestressed tendons and a filling material, carrying out anti-floating treatment on the hollow slab, and laying reinforcing steel bars on the slab surface; after the hidden project is checked and accepted, concrete pouring is conducted; the prestressed tendons are tensioned, and the tensioned ends are treated after tensioning; according to the structure obtained through the construction technology, a construction floor slab has better integrity, the product weight is light, moisture in concrete is not absorbed, the heat preservation performance is good, and the use performance is good; pipelines can be conveniently arranged on the floor by utilizing the characteristics of a construction structure; in addition, the requirement for a production site can be remarkably reduced, a large amount of land cost is saved, the production period is short, a traditional floor slab production process can continue to be used, and maturity and reliability are achieved.
本发明适用于建筑预应力空心板技术领域，提供了一种预应力空心板施工工艺，施工工艺中，先制作预应力筋并对预应力筋进行存放；支板底模和端模，在板底模和端模上放样，绑扎板底筋与肋梁钢筋；铺放预应力筋和填充材料，对空心板抗浮处理，铺放板面的钢筋；对隐蔽工程检查验收后，进行混凝土浇筑；对预应力筋进行张拉，张拉后对张拉端处理；本发明施工工艺得到的结构，使得施工楼板具有更好的整体性，产品质量轻、不吸收混凝土中的水分、保温性能很好，使用性能良好；且利用施工结构特点方便楼板布设管线；本发明还可以显著降低生产场地需求，节省了大量用地成本，而且生产周期快，可沿用传统的楼板生产工艺，成熟、可靠。
