Double-hole prestressed reinforced concrete laminated slab and manufacturing method thereof
The invention discloses a double-hole prestressed reinforced concrete laminated slab and a manufacturing method thereof, and relates to the technical field of building structural members. According to the double-hole prestressed reinforced concrete laminated slab and the manufacturing method thereof, the bearing energy efficiency can be improved, and overall stress performance is excellent; and meanwhile, construction, transportation and installation can be facilitated, thus labor is saved, and the production efficiency of a prefabricated slab is improved. The manufacturing method of the double-hole prestressed reinforced concrete laminated slab comprises the following steps that prestressed steel bars are tensioned before the prefabricated slab is poured, and after the strength of the prefabricated slab meets the design requirement, the prestressed steel bars are loosened to form a lower-layer prefabricated slab; a plurality of open semicircular holes are formed in the upper surface layer of the lower-layer prefabricated slab, and a closed circular hole is correspondingly formed below each open semicircular hole; and after the lower-layer prefabricated slab is in place on the construction site, reinforcing steel bars of a laminated layer are bound, concrete of the laminated layer is poured, and the concrete is poured into the open semicircular holes to form an engaged shear key for connecting the cast-in-place concrete laminated layer and the lower-layer prefabricated slab, so that the lower-layer prefabricated slab and the laminated layer cooperate together to form the double-hole prestressed reinforced concrete laminated slab.
一种双孔预应力钢筋混凝土叠合板及其制作方法，涉及建筑结构件技术领域，其能够提高承载能效，整体受力性能优良；同时能够便于施工、运输及安装，以节省人工而提高预制板生产效率。双孔预应力钢筋混凝土叠合板制作方法，包括以下步骤：在预制板浇筑之前先对预应力钢筋进行张拉，待预制板强度达到设计要求后，放松预应力钢筋，以形成下层预制板；下层预制板的上表层具有多个开口半圆孔，每个开口半圆孔下方对应设有闭合圆孔；待下层预制板在施工现场就位后，绑扎叠合层钢筋，浇筑叠合层混凝土，开口半圆孔浇筑混凝土后形成现浇混凝土叠合层与下层预制板连接的咬合抗剪键，以使下层预制板同叠合层共同协作，形成双孔预应力钢筋混凝土叠合板。
