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 difficulty is high, the loss of the formwork is large, and the cost is high. The prefabricated floor does not require on-site formwork, the construction period is short, and the cost is low. However, the prefabricated components are heavy and difficult to hoist. Cracks are prone to occur at the splicing parts of the components, and the integrity is poor. For example, the patent number is ZL0322765. 2. The patent titled a reinforced concrete assembled floor slab discloses a reinforced concrete prefabricated component. The prefabricated component is composed of plates and ribs, and the ribs have holes for piercing steel bars. The effective height of the steel bars in the pouring concrete is greatly reduced, which affects the two-way force balance of the floor slab, and it is difficult to form an equivalent two-way slab, etc.

Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0049] As shown in the accompanying drawings, the present invention includes a reinforced concrete strip bottom plate 1 and a reinforced concrete long longitudinal rib 2, which is characterized in that there is a hole 3 that runs through the longitudinal long rib 2 or \ and the bottom plate 1 in a transverse direction, and the hole 3 is provided with a tie longitudinal The long ribs 2 and the tensile and compressive parts 4 of the long bottom plate 1 are the tensile and compressive ribs or the tensile and compressive rods or the tensile and compressive piers. In each accompanying drawing, 1 is a strip bottom plate, 2 is a longitudinal long rib, 3 is a hole, and 4 is a tensile and compressive member. In the following drawings, those with the same number have the same description. As shown in Figure 1, the reinforced concrete ribbed prefabricated slab inc...

Abstract

A prefabricated reinforced concrete slab with rib for floor, roof, wall, foundation slab and bridge is composed of a long reinforced concrete slab as baseplate and a longitudinal long reinforced concrete rib, and features that it has the transverse holes passing through said longitudinal long rib and / or said baseplate and the pull and press resistant parts are arranged in said holes.

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 slabs and ribs, and the ribs have holes for passing steel bars. The thickness of the slab is large, which greatly reduces the effective height of the steel bars placed in the...
