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. A reinforced concrete prefabricated component. The prefabricated component is composed of plates and ribs, and the ribs have holes for piercing steel bars. This prefabricated component can be used as a formwork. However, the thickness of the plate is large, and it is inconvenient to pass steel bars and cannot be adjusted. The effective height of the steel bars placed in the cast-in-place concrete is greatly reduced, which affects the two-way force balance of the floor, making it difficult to form an equivalent two-way slab, etc.

Embodiment Construction

[0109] The present invention will be further described below in conjunction with the drawings and embodiments.

[0110] As shown in the drawings, the present invention includes a prefabricated slab 1, reinforced concrete 2, and is characterized in that the prefabricated slab 1 is composed of a bottom plate 3, a vertical pier 4, and a rod member 5. At least two vertical piers 4 are provided on the bottom plate 3 And at least two rods 5, the rods 5 are transversely arranged on the bottom plate 3, the rods 5 are spaced from the bottom plate 3 with a space distance 6, and the rods 5 are transversely connected to support at least two vertical piers 4, cast-in-situ reinforced concrete 2 and The prefabricated slab 1 constitutes a laminated slab, and the vertical pier 4 is a concrete pier. In the drawings, 1 is a prefabricated slab, 2 is a reinforced concrete, 3 is a bottom plate, 4 is a pier, 5 is a rod, and 6 is a space distance. In the following drawings, the same numbers have the same...

Abstract

A superimposed slab includes a precast slab (1) and reinforced concrete (2) and is characterized in that the precast slab (1) consists of a base plate (3), vertical piers (4) and member bars (5); wherein, the base plate (3) is provided with at least two vertical piers (4) and at least two member bars (5), the member bars (5) are transversely arranged on the base plate (3), the distances between the member bars (5) and the base plate (3) have spacing (6), the member bars (5) are transversely connected with and support at least two vertical piers (4); the member bars (5), the vertical piers (4) and the base plate (3) form the superimposed slab together, and the vertical piers (4) are concrete piers. The superimposed slab is suitable for the construction of various cast-in-situ floor systems, roof systems, wall bodies, foundation mats and road and bridge projects.

Description

(1) Technical field [0001] The invention relates to a laminated board. (2) Background technology [0002] At present, the domestically used reinforced concrete floor slabs include cast-in-place floor slabs and pre-cast floor slabs. The cast-in-place floor slab has good integrity, but requires on-site formwork and then pouring the concrete. The construction period is difficult, the formwork loss is large, and the cost is high. Formwork, short construction period, low cost, but prefabricated components are heavy, difficult to hoist, component splicing parts are prone to cracks, poor integrity, such as the patent number ZL0322765.2, the name is a kind of reinforced concrete assembly floor patent, which discloses A prefabricated reinforced concrete component. The prefabricated component is composed of plates and ribs. The ribs have holes through which steel bars are inserted. This prefabricated component can be used as a template. However, the thickness of this type of plate is large...
