Abstract

The utility model belongs to a building floor slab, particularly relates to a superimposed hollow slab. The superimposed hollow slab comprises a precast slab, internal molds and a cast-in-place layer arranged from the bottom up, wherein the internal molds are positioned in at least one internal mold concave pit arranged on the precast slab; and the internal mold concave pit is a cuboid. The utility model has the advantages that the superimposed hollow slab can be designed according to a two-way stress floor slab, so as to enhance the integrity of the slab; and the prefabricated part of the superimposed hollow slab can be produced in a factory in a large-scale way, so that the efficiency is improved, the quality is ensured, and the workload in the field is greatly reduced, as a result, the building cost is reduced.

Description

The overlapped hollow plate
Technical field
The utility model belongs to a kind of building floor, relates in particular to a kind of overlapped hollow plate.
Background technology
At present, because China's construction market is huge, the method for cast-in-situ concrete is adopted in building operations more, this job practices requires a large amount of job sites that is operated in to finish, need a large amount of workmans, labor strength is high, and operating efficiency is low, just cause be becoming tight work day for building, building costs significantly rises, and the site operation difficult quality guarantee, therefore at present in the urgent need to changing present form of construction work, reduce engineering cost, improve efficiency of construction and quality.
The utility model content
The purpose of this utility model is to provide a kind of overlapped hollow plate for the deficiency that production efficiency is low, workman's amount of labour is large, cost is high in the existing cast-in-situ floor technology, to accomplish scale production, reduces cost, saves the engineering time simultaneously.This overlapped hollow plate can be applied to all multi-rise buildings.
The overlapped hollow plate comprises precast plate, internal mold and the in-situ layer of bottom-up setting, and internal mold is in the internal mold pit that arranges on the precast plate, and pre-plugged is in length and breadth to reinforcing bar in the precast plate.
Internal mold pit in the utility model is rectangular build pit.Internal mold pit quantity is at least one.The shape of cross section of internal mold is circle or polygon.Laterally reach in the precast plate and vertically be provided with reinforcing bar, end reinforced is curved shape.
The utility model has the advantage of: 1. this utility model can be carried out large-scale production in factory, raises the efficiency, and ensures the quality of products; 2. at the scene workload significantly reduces, thereby reduces building costs; 3. all be the simple reinforcing bar that laterally or vertically arranges in the past the precast plate, the utility model laterally reaches and vertically is provided with reinforcing bar, simultaneously, laterally end reinforced is curved shape, in the cast-in-situ concrete of two precast plate edge joint positions, thereby so that the bottom transverse internal force between the precast plate can effective communication, after construction is finished, floor is in biaxial stress state, and the crack at effective confinement plate seam place.

The specific embodiment
Embodiment 1
Such as Fig. 1-4, this overlapped hollow plate has been embedded in reinforcing bar, and hollowcore slab comprises precast plate 1, internal mold 2 and the in-situ layer 5 of bottom-up setting, and internal mold 2 is in the internal mold pit 3 that arranges on the precast plate 1.
Internal mold pit 3 in the utility model is rectangular build pit.Internal mold pit 3 quantity are at least one, and length is fixed according to hollowcore slab length and concrete condition.The shape of cross section of internal mold 2 is circular.Laterally reach in the precast plate 1 and vertically be provided with reinforcing bar 4.Reinforcing bar 4 ends horizontal in the precast plate 1 are curved shape
During construction, customized precast plate 1 and internal mold 2 in factory first, precast plate 1 is embedded in reinforcing bar 4, behind building-site, interior external mold is assembled together, and then carries out at the scene the colligation of reinforcing bar 4 and internal mold 2, build at last remaining concrete, form in-situ layer 5, thereby finish the construction of floor.
Among Fig. 4, the quantity of internal mold 2 determines by the diameter of its internal mold pit 3 and internal mold 2, and the cross section of internal mold 2 is shaped as circle among this embodiment.
The utility model laterally and vertically be provided with reinforcing bar, simultaneously, horizontal end reinforced be curved shape, the weight capacity of raising overlapped hollow plate.
Embodiment 2
With embodiment 1, difference is structure with embodiment 1 and job practices, internal mold 2 cross sections be shaped as polygon.
