Abstract
The utility model relates to a rubber mandrel that precast reinforced concrete hollow component used, this rubber mandrel, including die body and air cock, the air cock setting is on the bottom surface of die body, and the key is: the die body side is provided with the strengthening rib. Be provided with the connecting piece of built -in fitting on the die body to increase the strengthening rib to the side of the die body, reduced the degree of wear of concrete with rubber mandrel, improved rubber mandrel's tough nature, thereby improved rubber mandrel's life.
Description
Technical field
The utility model relates to a kind of rubber mandrel that prefabricated reinforced concrete hollow unit is used.
Background technology
Rubber mandrel is a kind of inflatable, aerated core of shrinking, is used to form the sky of concrete componentChamber, in the time manufacturing hollow unit, in the middle of it is put into, and is filled with compressed air, the rear venting demoulding.Rubber mandrelCan replace original wooden model, bamboo mould, punching block, can be repeatedly used, be that one is fallenThe concrete goods auxiliary products of low cost, accelerating construction progress.
But, for the rubber mandrel of bridge construction, in use, rubber mandrel and concreteDirectly contact, easily wearing and tearing, have a strong impact on its durability, make full use of number of times few, and service life is short,And build in process and often to need pre-buried pipeline, wire casing etc. at concrete, existing rubber core film withoutMethod is tentatively fixed pre-buried parts, caused use inconvenient, how at the table of rubber mandrelBecome urgent problem in the fixing built-in fitting of face the service life of improving core film.
Utility model content
The defect existing in order to overcome above-mentioned prior art, the utility model provides a kind of rubber mandrel,On die body, be provided with the connector of built-in fitting, and increased reinforcement in die body side, reduced mixedThe degree of wear of solidifying soil and rubber mandrel, has improved the obdurability of rubber mandrel, thereby improves rubber coreThe service life of mould.
The purpose of this utility model can be achieved through the following technical solutions: a kind of rubber mandrel, bagDraw together die body and valve, valve is arranged on the bottom surface of die body, and key is: die body side is provided with reinforcementMuscle.
Described die body is shaped as cylinder, or prism.
Described valve is pore, or air-pump inflating valve.
Described reinforcement is shaped as wire, or banded.
On described reinforcement, be provided with groove, in groove, be provided with the connector that connects built-in fitting.
Described slot opening place is covered with grouting inserted sheet.
The beneficial effects of the utility model are:
Increase reinforcement in die body side, reduced the degree of wear of concrete and rubber mandrel, carriedThe high obdurability of rubber mandrel, thereby the service life of improving rubber mandrel. Reinforcement is shaped as lineShape or band shape, the obdurability of banded reinforcement is than strip reinforcement better effects if.
Die body is shaped as cylinder, or prism, goes for multiple Components Shape.
Airing form is air tube inflation or air-pump inflating, and air tube is inflated applicable die body small volume; GasIt is larger that pump is inflated applicable die body volume.
Be provided with various built-in fittings around in order to adapt to most die bodys, on this structural bead, be provided with littleGroove, in groove, be provided with and connect the connector of built-in fitting.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Specific embodiment 1, as shown in Figure 1, rubber mandrel, comprises cylindrical die body 1 and valve 2,Valve 2 is arranged on the bottom surface of die body 1, and the side of die body 1 is provided with the reinforcement 3 of wire, valve2 is pore.
This structure is reserved for cylinder component, and airing form adopts air tube inflation, is applicable to volumeLess rubber mandrel.
Specific embodiment 2, as shown in Figure 2, rubber mandrel, comprises cylindrical die body 1 and valve 2,Valve 2 is arranged on the bottom surface of die body 1, and the side of die body 1 is provided with banded reinforcement 3, valve2 is air-pump inflating valve.
This structure is compared with specific embodiment 1, and airing form adopts air-pump inflating, and single aeration amountGreatly, be relatively applicable to the larger rubber mandrel of volume.
Specific embodiment 3, as shown in Figure 3, rubber mandrel, comprises die body 1 and the valve 2 of cuboid,Valve 2 is arranged on the bottom surface of die body 1, and the side of die body 1 is provided with banded reinforcement 3, valve2 is air-pump inflating valve, is provided with little groove, the company of being provided with in groove on the reinforcement 3 of die body 1Connect the connector 4 of built-in fitting, and be provided with grouting inserted sheet, in the time not connecting built-in fitting, lid is located at grooveOn opening.
This structure is further improved to the rubber mandrel that is applicable to set up built-in fitting, in rubber mandrel sideThe connector that connects built-in fitting is installed on face reinforcement, built-in fitting is installed and can be greatly alleviated body of wall installationAfter frame, on the integrally-built impact of body of wall, this connector can be structure as a whole with rubber mandrel, also can beSplit type structure is provided with grouting inserted sheet simultaneously, in the time not articulating connector, grouting inserted sheet is covered at grooveUpper, avoid concrete that groove is blocked.
Specific embodiment 4, as shown in Figure 4, rubber mandrel, comprises die body 1 and the valve 2 of six prisms,Valve 2 is arranged on the bottom surface of die body 1, and the side of die body 1 is provided with banded reinforcement 3, valve2 is air-pump inflating valve, is provided with the connector 4 that connects foundation bolt on reinforcement 3.
This structure is applicable to the connector that built-in fitting is foundation bolt, and foundation bolt is specialized in and is embedded in concreteIn ground, the base of fix various machinery, equipment is used.
