[0002] At present, the reinforced concrete floor slabs used in China include cast-in-place floor slabs and prefabricated floor slabs. The cast-in-place floor slabs have good integrity, but they need to be molded on site, and then concrete is poured. The construction period is difficult, the loss of the formwork is large, and the cost is high. formwork, short construction period and low cost, but the prefabricated components are self-heavy, difficult to hoist, cracks are prone to occur at the splicing parts of the components, and the integrity is poor, such as the patent No. ZL0322765. A reinforced concrete prefabricated component. The prefabricated component is composed of plates and ribs, and the ribs have holes for passing steel bars. The thickness of the plates is large, so that the effective height of the steel bars placed in the cast-in-place concrete is greatly reduced, and the adjacent The spliced parts of the slabs are easy to crack, which affects the stability of the floor slab

Embodiment Construction
[0058] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0059] As shown in the accompanying drawings, the present invention includes a reinforced concrete strip bottom plate 1 and a reinforced concrete longitudinal long rib (2). The present invention is characterized in that one or two rib sides of the longitudinal long rib 2 have vertical grooves 3 or / and rib 4. In each accompanying drawing, 1 is a bottom plate, 2 is a long rib, 3 is a groove, and 4 is a convex line. In the following accompanying drawings, those with the same number have the same description. As shown in Figure 1, the reinforced concrete ribbed prefabricated slab includes a reinforced concrete bottom plate 1 and a reinforced concrete longitudinal rib 2, and vertical grooves 3 are arranged on the sides of the two ribs of the longitudinal long rib 2.
[0060] The feature of the present invention is that the ends of the long ribs 2 protrude...

The present invention relates to a reinforced concrete ribbed precast slab. It includes reinforced concrete long-strip base slab and reinforced concrete longitudinal long rib. It is characterized by that on one or two rib side surfaces of said longitudinal long rib several vertical recessed grooves or / and projected strips are set. Said reinforced concrete ribbed precast slab is applicable to cast-in-situ reinforced concrete or prestressed reinforced concrete laminated floor, roof, wall body, foundation bedplate and bridge beam, etc.
