Abstract
The utility model publicized a pneumatic type tube mold for in-situ concrete hollow floors, which is an inflatable bursa body (2) provided with a charging air inlet (1). Only enough air needs to be filled into the bursa body by the charging air inlet, and the utility model can be made in situ according to the length of the floor, and the transportation is convenient; in particular, the thinness and the weight of the bursa body are superior over the prior art, the light dead weight can reduces the weight of the in-situ concrete hollow floor, and further reduces the total weight of a building, and the construction cost of the construction project is greatly reduced.
Description
Technical field:
The utility model relates to the permanent loose tool that a kind of hollow cast slab is used.Especially a kind of hollow cast slab air filling type inner die.
Background technology:
Advantages such as at present, hollow cast slab is good from heavy and light, globality and continuity with it, construction is simple have been widely used in the various buildings.The job practices of hollow cast slab is inner die to be placed in the steel bar framework fluid concrete.Therefore, the quality of the inner die that hollow cast slab is used will directly have influence on the deadweight of hollow cast slab, also just directly have influence on the gross weight of building, have influence on the cost of construction work.For this reason, people are always at shape and the material of being devoted to study inner die.Up to the present. it must be a sealed hollow that all documents are all put down in writing this inner die. and must be to make by hard material.As the patent No. is 95216619.4, and " cross sectional shape of hollow mould can be trapezoidal, square, circular or other shape invention and created name in order to have put down in writing in the patent documentation of " with the cast-in-place hollow slab of permanent loose tool "; Can make by cheap material, as making " by hardboard, cardboard foamed plastics or potter's clay etc.The patent No. is 99232921.3, and invention and created name is " it is made up of horniness thin-walled tube and two plugs " also on the books in the patent documentation of " cast-in-place reinforced concrete filling light-wall pipe ".The patent No. is 93206310.1, and invention and created name " is provided with sidewall, makes the sidewall and the upper and lower end constitute totally-enclosed empty stomach shape polyhedral structure, establish reinforcing rib in the die housing for narration is also arranged in " shuttering member " around member; And they adopt rapid setting cement alkali resistant glass fiber (being called for short GRC) or magnesium chloride GRC or do not have husky ceramicite cement manufacturing ".Yet existing inner die can not on-the-spot be inflated owing to there is not charging connector, and the transportation difficulty is to such an extent as to the inner die that the large span cassette ceiling is used must the segmentation system of cutting be mounted to integral body again; Must make the enclosed cavity of two ends plug, the light-wall pipe manufacturing process that making complexity, especially GRC material are made is very complicated.
Summary of the invention:
The utility model is in order to solve existing problem in the prior art, a kind of hollow cast slab air filling type inner die simple, convenient transportation of making to be provided.
Technical solution of the present utility model is: a kind of hollow cast slab air filling type inner die, it constitutes the inflatable utricule 2 that is provided with charging connector 1.
The profile of described inflatable utricule 2 can be cylindricality, and its two ends are tabular or hemispherical.
The described inflatable utricule 2 outer reinforcing mats 3 that are provided with.
Described inflatable utricule 2 is made by fibrous material, is covered with thermoplastic film 4 in it.
The utility model is the inflatable utricule of being made by flexible material that has charging connector, during construction, sufficient gas in the utricule got final product by charging connector, therefore, and can be according to the length of floor, tailor at the scene, convenient transportation; Particularly thin, the weight of bladder walls then all is that prior art institute can not compare, and then can reduce the weight of hollow cast slab from heavy and light, has also just reduced the gross weight of building, thereby has greatly reduced the cost of construction work.

Fig. 4 is the structural representation of the utility model embodiment 3 utricules.
The specific embodiment:
As shown in Figure 1, 2: the utricule 2 of the utility model embodiment 1 is to make with macromolecular thermoplastic material or rubber, and it is shaped as cylindricality, and charging connector 1 is installed on the utricule 2.Can be prefabricated into the inner die that meets dimensional requirement according to the length of floor, on-the-spot inflation back construction and installation.Also can cut out according to the length of floor at the scene, with heat-sealing machine envelop materials be carried out heat seal, install charging connector 1, form the utricule 2 that is provided with charging connector 1, inflation is installed again.
Shown in Fig. 1,3: the utricule 2 of the utility model embodiment 2 is to make with macromolecular thermoplastic material or rubber, and it is shaped as cylindricality, and charging connector 1 is installed on the utricule 2, can put fiber reinforcing mat 3 outside the utricule 2.Can be prefabricated into the inner die that meets dimensional requirement according to the length of floor, on-the-spot inflation back construction and installation.Also can cut out according to the length of floor at the scene, with heat-sealing machine envelop materials be carried out heat seal, install charging connector 1, form the utricule 2 that is provided with charging connector 1, inflation is installed again.
Shown in Fig. 1,3: the utricule 2 of the utility model embodiment 3 is to make with fiber, applies one deck thermoplastic film 3 in fiber, and it is shaped as cylindricality, and charging connector 1 is installed on the utricule 2.Can be prefabricated into the inner die that meets dimensional requirement according to the length of floor, on-the-spot inflation back construction and installation.Also can cut out according to the length of floor at the scene, with heat-sealing machine envelop materials be carried out heat seal, install charging connector 1, form the utricule 2 that is provided with charging connector 1, inflation is installed again.
