Problems solved by technology

[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 splic

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), and is characterized in that there are vertical grooves 3 or / and on one or two rib sides of the longitudinal long rib 2 The protruding strip 4, the longitudinal steel bars 5 of the longitudinal long ribs 2 and the longitudinal steel bars 5 in the long bottom plate 1 are arranged in parallel. In each accompanying drawing, 1 is a bottom plate, 2 is a long rib, 3 is a groove, 4 is a convex line, and 5 is a steel bar. 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 gro...

Abstract

The ribbed prefabricated steel concrete plate includes one long steel concrete bottom plate and long longitudinal steel concrete ribs, and features that there are vertical notches and/or lugs in the long longitudinal ribs and longitudinal steel bars in the long longitudinal ribs set in parallel to those in the long bottom plate. The ribbed prefabricated steel concrete plate may be well combined with in-situ cast concrete with less tendency of cracking, and has the cooperative stress of the long longitudinal ribs and the long bottom plate, and raised integrity and bearing capacity. The present invention is suitable for use in in-situ cast or pre-stressed laminated reinforced concrete floor slab, roof, wall, foundation slab and hollow bridge, especially in laminated floor slab.

Description

(1) Technical field [0001] The invention relates to a reinforced concrete prefabricated panel with ribs. (2) Background technology [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-pl...
