Abstract
The utility model relates to the building floor, in particular to a box of a cast-in-place hollow floor, which comprises a hollow box body. The box is characterized in that the upper end face and the lower end face of the box body are respectively provided with fixed isolating ribs arranged in a cross shape, and a fiber net is arranged in the box body. When the utility model is used, the fiber net is arranged between the upper row of reinforced bars and the lower row of reinforced bars. The fixed isolating ribs on the upper end face and the lower end face of the box body make the upper end face and the lower end face of the box body and the upper row of reinforced bars and the lower row of reinforced bars isolated to form certain clearances, so that the concrete can be completely filled and well combined with the reinforced bars and the box body, thereby improving the construction quality and the seismic capacity of the floor. The utility model has the advantages of safe use, convenient construction, light weight, low construction cost, high quality and the like.
Description
Technical field:
The utility model relates to the superstructure of building, specifically a kind of cast-in-situ hollow building roof casing.
Background technology:
At present, in the great majority building, large span, the frame construction of large bay has adopted cast-in-place concrete building roof (also claiming the interlayer floor), this superstructure is made by steel concrete, for economical with materials, reduce cost, improve shock resistance, reduce load bearing wall and bearing column size, increase usable floor area etc., require superstructure weight light as far as possible, people have invented the cast-in-situ hollow building roof technology, it is to have set up internal mold when floor framing in superstructure, internal mold peace structure is divided into solid internal mold and hollow internal mold, tube in-core mould and cabinet inner module, hollow internal mold is because economical with materials, advantage such as in light weight is used widely, the intracardiac mould of hollow cylinder has: plastic pipe, metallic coil, cement core tube etc., plastic pipe, metallic coil etc. are because cost is higher, therefore seldom use in the hollow building cover, cement core tube is because transportation loading and unloading, be easy to the plug phenomenon that drops in the construction and installation process, the percentage of damage height, hollow rate is low, also need a large amount of fixed supports and arrangement of reinforcement, the construction trouble, so hollow box body is used widely in cast-in-situ hollow building roof, existing hollow box body is the square shape shape of being with groove, in order to improve weight capacity, what have also is provided with ribs in groove, the casing of existing hollow box body and last placing of reinforcement and following placing of reinforcement need be fixed and isolate with fixed support, so that concrete and reinforcing bar, casing in conjunction with better, it is poor to have casing and last placing of reinforcement and a following placing of reinforcement isolation effect, inconvenient operation etc.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of easy construction, working efficiency height is provided, can reduces the support bracket fastened cast-in-situ hollow building roof casing that need not of construction costs.
The utility model can reach by following measure:
A kind of cast-in-situ hollow building roof casing is provided with hollow box body, it is characterized in that the both ends of the surface up and down of casing are respectively equipped with fixedly barrier ribs.
Fixedly barrier ribs in the utility model is cross-shaped, can be cross-shaped, also can be the diagonal cross-like, with the intensity that improves casing, make concrete combine better with reinforcing bar, casing.
Fixedly barrier ribs in the utility model is made by concrete, can be provided with fleece in it, also can be provided with reinforcing bar, to improve the fixedly intensity of barrier ribs.
When the utility model uses, place it between placing of reinforcement and the following placing of reinforcement, the fixedly barrier ribs of the upper and lower end face of casing is with upper and lower end face and the last placing of reinforcement and the following placing of reinforcement isolation certain interval of casing, concrete is fully entered, make concrete combine better with reinforcing bar, casing, improved the construction quality and the shock resistance of superstructure, have safe in utilization, easy construction, in light weight, reduce advantages such as construction costs south amount is good.
Description of drawings:
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is an another kind of structural representation of the present utility model.
Fig. 4 is the B-B sectional view of Fig. 3.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings, a kind of cast-in-situ hollow building roof casing, be provided with hollow box body 1, hollow box body 1 is same as the prior art, this does not give unnecessary details, the both ends of the surface up and down of casing 1 that are characterised in that of the present utility model are respectively equipped with fixedly barrier ribs 2, fixedly barrier ribs 2 is cross-shaped, can be cross-shaped, also can be the diagonal cross-like, make by concrete, can be provided with fleece in it, also can be provided with reinforcing bar, to improve the fixedly intensity of barrier ribs, during use, place it between placing of reinforcement and the following placing of reinforcement, on the casing, the fixedly barrier ribs of lower surface is with on the casing, lower surface and last placing of reinforcement and following placing of reinforcement are isolated certain interval, concrete is fully entered, make concrete and reinforcing bar, casing has improved the construction quality and the shock resistance of superstructure in conjunction with getting better, the utlity model has safe in utilization, easy construction, in light weight, reduce advantages such as construction costs south amount is good.
