Two ends of the steel bar extend out of two sides of the concrete bottom plate.
Further, preferably, the first reinforcing steel bar is made of ordinary reinforcing steel bars, and the second reinforcing steel bar is made of prestressed high-strength steel wires.
Further, as preferred, its characterized in that the concrete rib includes reinforcing bar three, support frame and sleeve, the support frame sets up inside the concrete rib, and the sleeve sets up and is used for the poling line in concrete rib upper portion. The concrete ribs are cast in situ together with the concrete bottom plate.
Further, it is preferable that the concrete rib is prefabricated and then the concrete bottom plate is poured.
Further, it is preferably characterized in that the sleeve is provided on the concrete rib for threading the pipe.
Compared with the prior art, the invention has the beneficial effects that: the transverse steel bars are designed to be more beneficial to the bending resistance and the transverse crack resistance of the precast concrete thin plate; the concrete ribs are prefabricated in advance, so that the member production is more convenient, and the industrial production is easier to realize; due to the arrangement of the pipeline perforated sleeve, the rib prefabricating process and the rib prefabricating and conveying are simpler and more convenient.
