Concrete prefabricated slab suitable for fabricated pavement
The invention provides a concrete precast slab suitable for a fabricated pavement, and belongs to the technical field of road construction. The concrete precast slab provided by the invention comprises a pavement slab body and reinforcing steel bars pre-buried in the pavement slab body, the pavement slab is square, and an interface is formed in the edge of the pavement slab; the pre-embedded steel bars are parallel to the edge of the pavement slab and are uniformly distributed and are staggered in the pavement slab body in a latticed manner; the two steel bars close to the edge of the pavement slab extend towards the two ends, and the extending parts are set as lifting points; all the panels are connected through steel bars welded with lifting points, and the steel bars welded with the lifting points serve as dowel bars. The two ends of the inner reinforcing steel bar extend to form a part, the part can serve as a lifting point to be arranged on the two sides of the pavement slab body, the lifting point is directly welded, construction is convenient, and the part can be continuously used as the lifting point after slab replacement in the later period is directly cut off; and meanwhile, the lifting points can be directly used as dowel bars after being welded, the plates are connected into a whole, and the inter-plate load transfer efficiency is high.
本发明提供了一种适用于装配式路面的混凝土预制板，属于道路施工技术领域。本发明提供的混凝土预制板，包括路面板本体和预埋在路面板本体内的钢筋；所述路面板为方形，并在路面板边设置有接口；所述预埋的钢筋与路面板边平行均匀分布且在路面板本体内呈网格状交错；靠近路面板边的两根钢筋向两端伸出，伸出部分设置为吊点；各路面板之间采用焊接吊点的钢筋进行连接，吊点焊接后的钢筋作为传力杆。通过使内部的钢筋延的两端延伸出一部分，该部分可作为吊点在路面板本体的两侧，吊点直接焊接，方便施工，后期换板直接切开，可继续用来做吊点；同时本发明将吊点焊接之后可直接作为传力杆，板块连成整体，板间传荷效率高。
