Problems solved by technology

[0002] At present, the reinforced concrete floor slabs used in China include cast-in-place slabs and prefabricated slabs. The cast-in-place 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 in the splicing parts of the components, and the integrity is poor, such as the patent No. ZL0322765.

Example Embodiment

[0058] The present invention will be further described below in conjunction with the drawings and embodiments.

[0059] As shown in the drawings, the present invention includes a long reinforced concrete bottom plate 1 and a reinforced concrete longitudinal long rib 2. It is characterized in that the long bottom plate 1 has a transverse groove 3 or / and a rib 4, and at least one connecting hole 5 The two sides of the longitudinal rib 2 are connected. In the drawings, 1 is a bottom plate, 2 is a long rib, 3 is a groove, 4 is a protruding strip, and 5 is a hole. In the following drawings, the same numbers have the same descriptions. As shown in Fig. 1, the reinforced concrete ribbed prefabricated slab includes a reinforced concrete bottom plate 1 and a reinforced concrete longitudinal rib 2. The long bottom plate 1 has a transverse groove 3 and a connecting hole 5 connects the two sides of the longitudinal long rib 2.

[0060] The feature of the present invention is that the long rib...

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 transverse notches and/or lugs in the long steel plate and at least one transverse through hole in the long longitudinal ribs. 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...
