Background technology:
Cast-in-situ reinforced concrete hollow slab has been owing to reduced the consumption of concrete and optimized floor slab structure, thereby widely in the application project structure.The making of steel bar reinforced hollow concrete roof cast-in-situs mainly all is by hollow internal mold is set in concrete at present, it mainly acts on by the internal mold concrete of finding time, and the weight reduction economical with materials is improved the stress performance of floor slab structure simultaneously, improve the function of use of whole building, have remarkable advantages such as energy-saving and environmental protection.
A kind of internal mold that present cast-in-situ reinforced concrete hollow slab is used is made up of cement thin-walled pipe and two plugs, will adopt connecting elements that light-wall pipe is connected with reinforcing bar in construction, or with fixed component cylindrical shell be fixed.Its subject matter one is that the internal mold location is inaccurate, and the skew of internal mold position takes place easily; The 2nd, need in the construction to connect and fixed component, work efficiency is low, the cost height; The 3rd, concrete pouring process internal mold anti-floating ability.
The utility model content:
Technical problem to be solved in the utility model is: the above-mentioned deficiency at prior art, a kind of cast-in-situ reinforced concrete hollow slab is provided, and can make internal mold easy for installation, accurate positioning, the anti-floating ability of internal mold is strong in the construction, saves construction cost simultaneously.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of cast-in-situ reinforced concrete hollow slab, it comprises beam between wall column, cast-in-situ reinforced concrete, the hollow internal mold of band mounting bracket, reinforcing bar comprises reinforcing bar at the bottom of the plate, plate top reinforcing bar, and at the bottom of the junction plate with the connecting reinforcement of plate top reinforcing bar, hollow internal mold is positioned between cast-in-situ reinforced concrete, hollow internal mold two ends have end cap, its characteristic point is: described reinforcing bar also comprises spacer bars, the mounting bracket lower end of described hollow internal mold is provided with draw-in groove, this spacer bars is fastened in the draw-in groove, and reinforcing bar is affixed at the bottom of spacer bars and the plate.
The opening direction of the draw-in groove of described mounting bracket can be any direction, and can be provided with the hole that runs through near the draw-in groove, and the bundle silk colligation that described hollow internal mold can be by being interspersed in hole is on the spacer bars that fixes in draw-in groove.
Described hollow internal mold distributes as net shape, is arranged in parallel, is crisscross arranged in described floor or radial distribution.The described Cast-in-place concrete that is filled in hollow interior intermode constitutes the vertical rib of Cast-in-place concrete, and this vertical rib forms " worker " font or the dark girt strip of T shape.The profile of described hollow internal mold is cylindrical, elliptical cylinder-shape, cube, cuboid, inverted pyramid body, cone, or its cross section is square top and round bottom shape, circular upper part and square lower part shape.Described hollow internal mold can be made by macromolecular material, metal material, wood materials, Inorganic Non-metallic Materials (as cement, pottery).
Above-mentioned hollow internal mold can link together by Zha Si and reinforcing bar, and is linked as integral body by Cast-in-place concrete, and internal mold does not take out after the hardening of cement, forever is positioned in the floor.Internal mold can be positioned at the vertical middle position of floor in floor, also can be positioned at portion or portion on the upper side on the lower side.
Described mounting bracket can be connected as a single entity with end cap, or is located at other positions of hollow internal mold.
Compared with prior art, the utility model has the advantages that:, simultaneously hollow internal mold is fixed at the bottom of the plate on the reinforcing bar by the positioning and fixing of reinforcing bar at the bottom of the plate, in construction, can play the anti-floating effect, thereby hollow internal mold can accurately be located, while is easy for installation, can save the construction cost of cassette ceiling.

Fig. 1 is the schematic diagram of the utility model cassette ceiling.
Fig. 2 is the structural representation of hollow internal mold of the present utility model.
Fig. 3 is the connection diagram of reinforcing bar at the bottom of the hollow internal mold of the utility model and spacer bars and the plate.
Fig. 4 is the connection diagram of reinforcing bar and hollow internal mold and baffle plate at the bottom of the plate of the present utility model.
The specific embodiment:
As shown in Figures 1 and 2, the utility model is a kind of cast-in-situ reinforced concrete hollow slab, and this cassette ceiling is made up of beam between wall column 1, reinforcing bar 2, Cast-in-place concrete 3 and hollow internal mold 4.The cassette ceiling side is provided with beam 1 between wall column; Reinforcing bar 2 comprises reinforcing bar 21 at the bottom of the plate, plate top reinforcing bar 22, connecting reinforcement 23, and connecting reinforcement 23 will be connected with plate top reinforcing bar at the bottom of the plate; Hollow internal mold 4 two ends have end cap 41, and has a mounting bracket 42, mounting bracket 42 is connected as a single entity with end cap 41, mounting bracket 42 lower ends have draw-in groove 43, and the opening of draw-in groove 43 can be any direction, in the present embodiment, hollow internal mold 4 and connecting reinforcement 23 are alternately, and the segmentation setting, the opening of draw-in groove 43 is oppositely to be provided with, and consistent with end cap 41 directions.Hollow internal mold 4 is by being connected with reinforcing bar and being linked as an integral body by the Cast-in-place concrete cast.
Described reinforcing bar 2 also comprises spacer bars 24, as shown in Figure 3, spacer bars 24 can be fastened in the draw-in groove 43 of hollow internal mold 4, and be connected with reinforcing bar 21 at the bottom of the plate of vertical setting, non-spacer bars 25 at the bottom of 24 of spacer barss also can be arranged plate in parallel in twos, non-spacer bars 25 is connected for structure reinforcing bars and with reinforcing bar at the bottom of the plate 21 at the bottom of this plate.
