Abstract
The utility model belongs to the technical field of moulds for beam slab prestressing holes, in particular to a simple and easy inflatable mould for manufacturing a beam slab prestressing hole. The simple and easy inflatable mould is characterized by comprising a columnar mould body made of elastic materials; one end part of the mould body is provided with a blocking plug equipped with an air tap; and as a further improvement, a back cover piece is arranged on an end opposite to the end equipped with the blocking plug of the mould body. After concrete setting, gas in the mould body is discharged; because the concrete is not adhesive to rubber, after discharging the gas, the mould body is separated from the wall of the beam slab prestressing hole and can be taken out directly. Thus, the mould body can be reused, and the simple and easy inflatable mould can not only save increasingly scarce energy sources (such as metal materials or plastic), but also greatly reduce the production cost of bridge beam slabs, and is convenient to transport and easy to use.
Description
Technical field
The utility model belongs to makes the girder plate prestress hole technical field of mold, relates in particular to and makes the simple and easy inflating die of girder plate prestress hole.
Background technology
At present, in bridge beam slab manufacturing process, in order to form girder plate prestress hole (steel strand stretch-draw use), often before cast concrete, be embedded in the beam reinforced steel bar cage with metal bellows or plastic film capicitor, after concrete setting, metal bellows or plastic film capicitor and concrete setting together, thereby form girder plate prestress hole.After the bridge beam slab completed, metal bellows or plastic film capicitor can not take out and stay in the bridge beam slab, cause the waste of metal tube or plastic material, have increased the production cost of bridge beam slab.
The utility model content
Problem to be solved in the utility model just provides a kind of alternative metals bellows or plastic film capicitor, the production cost of reduction bridge beam slab, the simple and easy inflating die of manufacturing girder plate prestress hole reusable, convenient for production.
For addressing the above problem, the utility model is made girder plate prestress hole and with the technical scheme that simple and easy inflating die adopts is: comprise the columnar mould body of being made by elastomeric material, be provided with the obstruction that has valve in an end of described die ontology.
Its additional technical feature is:
Have a relative end that stops up an end at described die ontology and be provided with the back cover sheet;
Described back cover sheet is provided with second valve;
Be provided with the braiding enhancement Layer at described die ontology internal face;
Described braiding enhancement Layer is chemical fibre layer of cloth or canvas layer;
Internal face at described braiding enhancement Layer is provided with sealant;
Described obstruction and described die ontology junction are provided with clamp;
The outer surface of described die ontology is a shiny surface.
The outer surface of described die ontology is provided with projection.
Manufacturing girder plate prestress hole provided by the utility model with simple and easy inflating die compared with prior art, have the following advantages: one, owing to comprise the columnar mould body of making by elastomeric material, end at described die ontology is provided with the obstruction that has valve, before cast concrete, one end of die ontology opening is tied up, become inflatable chamber, inflate to inflatable chamber by valve, be embedded in the beam reinforced steel bar cage, wait concrete initial set after, bleed off the gas in the inflatable chamber, because concrete and rubber adhesion frictional force are little, after gas bleeds off, take out die ontology and get final product, prestress hole is smooth, this mould is convenient compared with the mould production that two ends have shutoff face, and production cost is lower, ties up convenient; Its two owing to have a relative end that stops up an end at described die ontology and be provided with the back cover sheet, back cover sheet and die ontology are sulfided into one, like this, need not tie up in the use, use conveniently, and process also simple; Its three because described die ontology inside is provided with the braiding enhancement Layer that canvas or other materials are made, has increased and made the intensity of girder plate prestress hole with simple and easy inflating die; Its four owing to be provided with sealants such as elastomeric material layer or plastic layer, scratch when having prevented to use and cause gas leakage because of die ontology at the internal face of described braiding enhancement Layer, improved the service life of Inflatted rubber tyre mould.

The specific embodiment
Below in conjunction with accompanying drawing concrete structure and the use principle of the utility model manufacturing girder plate prestress hole with simple and easy inflating die is described in further details.
As depicted in figs. 1 and 2, the utility model is made girder plate prestress hole and is comprised the columnar mould body of being made by elastomeric material 1 with simple and easy inflating die, be provided with obstruction 2 in an end of die ontology 1, stop up 2 and be provided with valve 3, valve 3 is provided with switch 12.Obstruction 2 is preferably adopted bonding way with die ontology 1 junction, in die ontology 1 arranged outside clamp 10 is arranged.Before cast concrete, as shown in Figure 2, the end that die ontology 1 does not stop up is tied up, form inflatable chamber 4, inflate in inflatable chamber 4 by valve 3, be embedded in the beam reinforced steel bar cage, wait concrete initial set after, open switch 12, bleed off the gas in the inflatable chamber 4, because concrete and rubber adhesion frictional force are little, after gas bleeds off, take out die ontology 1 and get final product, prestress hole is smooth, this mould is convenient compared with the mould production that two ends have shutoff face, and production cost is lower, ties up convenient.The die ontology 1 that takes out can be reused, and has not only saved the energy (metal material or plastics) of growing tension.Also greatly reduce the production cost of bridge beam slab.And convenient transportation.
As Fig. 1, Fig. 3 and shown in Figure 4, make the intensity of girder plate prestress hole in order to have increased with simple and easy inflating die, die ontology 1 inside is provided with the braiding enhancement Layer 5 that materials such as chemical fibre layer of cloth or canvas layer are made.
In use, die ontology 1 and sand grains friction, when air pressure was big, gas leakage had easily reduced and has made the service life of girder plate prestress hole with simple and easy inflating die.In order to address the above problem,, be provided with the sealant 6 that elastomeric material or plastic or other material are made at the internal face of braiding enhancement Layer 5 as Fig. 1, Fig. 3 and shown in Figure 4.Certainly, also braiding enhancement Layer 5 can be set directly at die ontology 1 inside.The internal face of die ontology 1 just becomes sealant 6.
The outer surface of die ontology 1 is cylindrical under inflated condition or the cross section is oval column, as shown in Figure 3 and Figure 4.
In order to make the outside wall surface and the concrete of die ontology 1 break away from easily, as shown in Figure 4, be shiny surface or matsurface with the outer surface of die ontology 1.Certainly, also can be as shown in Figure 3, the outer surface of die ontology 1 is provided with projection 9.Projection 9 can be strip, corrugated or point-like.
As shown in Figure 5, die ontology 1 can be designed as an end and has obstruction 2, has back cover sheet 8 at the other end, and back cover sheet 8 is structure as a whole with die ontology 1 sulfuration, certainly, can be provided with second valve 11 by back cover sheet 8.
Certainly, also second valve 11 can only be set on back cover sheet 8, and in obstruction 3, valve be set.
