Abstract
The utility model discloses an internal form for cast-in-situ concrete, comprising a barrel body, an inner lining, an end cover making both ends of the barrel fixedly connected and sealed, and at least one locating bracket fixing the barrel body in the reinforced concrete. The locating bracket is arranged with a pi-shaped clamping groove or a gamma-shaped clamping seat for fixing steel bars, and the opening direction of the clamping groove or clamping seat depends on the direction of the steel bars in the concrete. The utility model has the advantages of more convenient installation of the internal form, precise locating, strong anti-floating capacity of the internal form, and economizing construction cost.
Description
Technical field:
The utility model relates to technical field of buildings, refers to a kind of internal mold that is used for cast-in-situ reinforced concrete especially.
Background technology:
The making of steel bar reinforced hollow concrete roof cast-in-situs is by hollow or solid internal mold (or claim core) is set in concrete, and it mainly acts on by the internal mold concrete of finding time, and weight reduction economical with materials consumption improves the stress performance of floor slab structure simultaneously.
And the hollow internal mold of using always on the existing engineering is a kind of thin-wall internal-mould, form by pipe and two plugs, in construction, to adopt connector that thin-wall internal-mould is connected with reinforcing bar, or internal mold is fixed with immobilization material, to guarantee that internal mold is not shifted in work progress, solve the anti-floating problem of internal mold in the concrete pouring process simultaneously, but it is inaccurate also to exist the internal mold location, easily displacement, the problem of anti-floating ability.
The utility model content:
Technical problem to be solved in the utility model is: at the above-mentioned deficiency of prior art, provides a kind of internal mold that is used for cast-in-situ reinforced concrete, makes internal mold easy for installation, and accurate positioning, the anti-floating ability of internal mold is saved construction cost simultaneously in the increase construction.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of internal mold that is used for cast-in-situ reinforced concrete, comprise hollow cylindrical shell, be located at liner in the cylindrical shell, the cylindrical shell two ends are connected firmly the end cap of sealing and be at least one cylindrical shell is fixed in locating support in the steel bar concrete, be characterized in: described locating support lower end is provided with the fixedly clamping structure of reinforcing bar.
Described clamping structure is " Contraband " shape draw-in groove or " " shape deck, and the opening direction of draw-in groove or deck can comprehensively be provided with according to the direction of fixing reinforcing bar, and has through hole on the described locating support.
The cylindrical shell of described internal mold is formed by connecting by surrounding between limit and limit by the sheet material more than one or one, as shown in Figure 3.The cylindrical shell outer shape of above-mentioned internal mold is decided by the liner shape, and its cylindrical shell profile is cylindrical, elliptical cylinder-shape, cube, cuboid, pyramid body, cone, block, or the cylindrical shell cross section is square top and round bottom shape, circular upper part and square lower part shape.And can all or part of filled and process in cylindrical shell, the mixture of plastic foamed, macromolecular material, metal material, wood materials, Inorganic Non-metallic Materials (as cement, pottery) or organic matter and inorganic matter.
The quantity of described liner is 1-4, can establish the hole on the liner alleviating cylindrical shell weight, and also can add the backstay of secure liner in the cylindrical shell, and the quantity of backstay is decided according to the distance between liner.
Described locating support and end cap form the end cap that an integral body promptly can be produced the band locating support, or locating support is connected on the end cap or cylindrical shell is inside and outside.Between described locating support and end cap, locating support and cylindrical shell, cylindrical shell and end cap, sheet material be connected to that splicing, profile of tooth are connected, riveted joint, thermosol connect, cold cut connects, tongue and groove connects, snap close connects, banding connects, compress connection, welding, nailing connect.
Above-mentioned cylindrical shell, liner, end cap, locating support can be made by the mixture of macromolecular material, metal material, wood materials, Inorganic Non-metallic Materials, organic matter and inorganic matter.Compared with prior art, the utility model has the advantages that: by on the locating support of internal mold, being set to the clamping structure of draw-in groove or deck, internal mold is connected with reinforcing bar in the reinforced concrete member better by clamping structure, can increases the anti-floating power of the internal mold when building steel bar concrete; Simultaneously, locating support can be installed on cylindrical shell or the end cap, internal mold is accurately located in structure or member, on locating support, have through hole, can attach in the through hole and prick silk, locating support firmly is banded in above the reinforcing bar, support draw-in groove or deck disengaging reinforcing bar in the time of can preventing that vibrator from vibrating by pricking silk, effectively prevent internal mold come-up in the work progress, solved the common fault of come-up displacement in other type internal mold construction fully.
Description of drawings:
Fig. 1 is an embodiment schematic diagram of the present utility model.
Fig. 2 is embodiment illustrated in fig. 1 and the user mode figure building reinforcing bar.
Fig. 3 is the sectional drawing that the utility model internal mold cylindrical shell connects.
Label declaration:
3 locating supports, 31 draw-in grooves
32 decks, 33 through holes
4 liners, 5 backstays
6,61,62,63 reinforcing bars 7 are pricked silk
The specific embodiment:
As shown in Figure 1, internal mold comprises cylindrical shell 1, end cap 2, two locating supports 3.End cap 2 connects firmly sealing with cylindrical shell 1 two ends, and locating support 3 is arranged on the end cap 2, is wholely set with end cap 2.One location support 3 is provided with " Contraband " shape draw-in groove 31, and another locating support 3 is provided with " " shape deck 32.Also be provided with liner 4 in the cylindrical shell 1, in the present embodiment, the quantity of liner is 3, also is provided with the backstay 5 of secure liner 4 in the cylindrical shell 1.
As shown in Figure 2, when internal mold is installed, can snap in internal mold draw-in groove 31 on the reinforcing bar 61 earlier, then deck 32 is stuck on another reinforcing bar 62, thereby internal mold can be fixed on the building reinforcing bar with fixing of 63 of other reinforcing bars by the reinforcing bar 6 of building.Draw-in groove 31 can be decided according to the direction of reinforcing bar 6 with the direction of deck 32.Offer through hole 33 on the locating support 3 in addition, prick silk 7 and can pass through hole 33, during construction can with prick silk 7 locating support 3 colligations on reinforcing bar 6, thereby, can better strengthen the location and the anti-floating effect of internal mold.
