Prestress prefabricated floor slab, both-way prestress prefabricated floor slab and manufacturing method
The invention provides a prestress prefabricated floor slab. A prefabricated slab body and a first prestress steel bar extending in the first direction of the prefabricated slab body are included. A hole way penetrating through the prefabricated slab body is arranged on the prefabricated slab body in the second direction and is suitable for containing a second prestress steel bar. The invention further provides a both-way prestress prefabricated floor slab comprising the prestress prefabricated floor slab and a manufacturing method of the both-way prestress prefabricated floor slab comprisingthe prestress prefabricated floor slab. The second prestress steel bar is used for penetrating through hole ways of a plurality of prestress prefabricated floor slabs, the multiple prestress prefabricated floor slabs are connected in series, then the both-way prestress floor slab can be achieved by applying tension to the second prestress steel bar and fixing the second prestress steel bar and themultiple prestress prefabricated floor slabs, the work procedure of the both-way prestress floor slab is simplified, operation difficulty is lowered, and the floor slab stress state is improved.
本公开提供了一种预应力预制楼板，包括预制板本体及沿所述预制板本体第一方向上延伸的第一预应力钢筋，所述预制板本体的第二方向上设有贯通所述预制板本体的孔道，所述孔道适于放置第二预应力钢筋。本公开还提供了一种包含上述预应力预制楼板的双向预应力预制楼板以及一种包含上述预应力预制楼板的双向预应力预制楼板的制作方法。使用第二预应力钢筋穿过若干预应力预制楼板的孔道，将若干所述预应力预制楼板串接，进而可以通过在第二预应力钢筋上施加张力并对第二预应力钢筋、若干预应力预制楼板进行固定就能实现双向预应力楼板，简化双向预应力楼板的工序及降低操作难度，并改善楼板的受力状态。
