Problems solved by technology

But there are the following disadvantages: due to the influence of the thickness of the bottom plate, the distance between the perforated steel bar and the bottom surface of the bottom plate is relatively large, and the performance of the perforated steel bar cannot be fully utilized.

Embodiment Construction

[0011] refer to Figure 1-Figure 5 , the ribbed reinforced concrete prefabricated slab includes a reinforced concrete bottom plate 1, a longitudinal rib 2, and a prestressed steel bar 3. There are through holes 5 on both sides of the lower and lower sides of the reinforced concrete longitudinal rib 2, and there are grooves on the bottom plate corresponding to the holes 5. 4. When assembling the floor slabs, put a plurality of reinforced concrete prefabricated slabs close together, pass through the holes 5 on both sides of the longitudinal rib 2 of the prefabricated slabs through the steel bars 6, place them on the groove 4 of the bottom slab, connect multiple reinforced concrete prefabricated slabs, and then pour The concrete 7 is filled and leveled, so that the prefabricated slab, the perforated steel bar 6 and the cast-in-place concrete 7 are integrated. Since the perforated steel bar 6 is placed at a lower position, the performance of the perforated steel bar 6 can be full...

Abstract

The invention discloses a ribbed reinforced concrete prefabricated board, comprising a reinforced concrete base plate, a longitudinal rib and prestressed reinforcing steel bars, wherein through holes are drilled at two sides of the longitudinal rib of the reinforced concrete prefabricated board, and grooves are formed at the positions, corresponding to the through holes, of the base plate. A floor slab is formed by assembling a plurality of the reinforced concrete prefabricated boards, the hole-penetrating reinforcing steel bars penetrate through the holes at two sides at the lower part of the longitudinal ribs of the prefabricated boards and are placed on the grooves on the base plates, meanwhile, a plurality of reinforced concrete prefabricated boards are connected, and concrete is poured then for flatness. Because the placement positions of the hole-penetrating reinforcing steel bars are lower, the performance of the hole-penetrating reinforcing steel bars can be used fully, and the grooves on the base plates can be used for enhancing the cementation between the prefabricated boards and the concrete, so that the integral performance of the floor slag is enhanced.

Description

Technical field: [0001] The invention relates to the field of building construction, in particular to a ribbed reinforced concrete prefabricated slab. Background technique: [0002] Ribbed reinforced concrete prefabricated component slabs (03227765.2) are commonly used to assemble floor slabs. This ribbed prefabricated component slab has holes on both sides of the longitudinal rib. When assembling the floor slab, pass the steel bars through the holes on both sides under the longitudinal rib of the prefabricated component, connect multiple reinforced concrete prefabricated components, and pour in the groove formed by the prefabricated components. Concrete integrates prefabricated components, existing steel bars, and cast-in-place concrete. This kind of prefabricated floor slab has good integrity, can bear two-way load, does not need on-site formwork, and has a short construction period. However, there are the following disadvantages: due to the influence of the thickness of...
