Abstract
The utility model discloses a bridge internal mold, which comprises an internal mold main body. The internal mold main body comprises an outer wall and a plurality of support walls. The outer wall and the support walls are connected with each other and molded in an integrative manner; and a plurality of cavities are formed between the outer wall and the support walls. The utility model has the advantage of reducing cost and decreasing resource waste, and is widely suitable for engineering construction projects such as freeway bridges and various bridges.
Description
Technical field
The utility model relates to the bridge construction field, especially relates to a kind of bridge internal mold.
Background technology
In the prior art bridge internal mold has and adopts the steel work internal mold, has to adopt the rubber internal mold; If take out internal mold when adopting the steel work internal mold then time-consuming, do not take out the steel work internal mold and then be unfavorable for alleviating of bridge construction deadweight; Employing inflating rubber internal mold, can cause floating mould, building of bridge main body structure caused adverse effect; Therefore, adopting foamed plastics at present is that the internal mold of main body is commonplace, and foamed plastics is in light weight, needn't take out after building, and it is relatively good to build effect.But the foamed plastics internal mold all is a solid construction at present, adopts the solid construction waste material, thereby brings higher cost, therefore need carry out structure of modification to existing bridge internal mold, to reduce cost, saves national resources.
The utility model content
In view of this, the purpose of this utility model provides a kind of bridge internal mold, helps reducing cost, and reduces the wasting of resources.
For achieving the above object, the utility model by the following technical solutions:
Bridge internal mold of the present utility model comprises the internal mold main body, and described internal mold main body comprises outer wall and some supporting walls, and outer wall and each supporting walls are coupled to each other and are one-body molded, forms some cavitys between outer wall and each supporting walls.
Further, the lateral surface of described outer wall is provided with back-up coat.
Further, described back-up coat comprises adhesive layer and grid layer of cloth, and adhesive layer is between the lateral surface and grid layer of cloth of outer wall.
Further, described grid layer of cloth adopts fiberglass gridding cloth.
Further, described internal mold main body adopts polystyrene material.
The beneficial effects of the utility model are: because the utility model bridge internal mold adopts hollow-core construction, reduced the use amount of material, therefore helped reducing cost, reduced the wasting of resources; Spraying adhesive also is provided with grid cloth, has not only increased bridge internal mold and concrete adhesion stress, and improves the weight capacity of bridge internal mold.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following manual, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, bridge internal mold of the present utility model comprises an internal mold main body 5 when implementing, internal mold main body 5 adopts polystyrene foam plastics to make, internal mold main body 5 comprises an annular outer wall 1 and three supporting walls 2 on the structure, annular outer wall 1 and be coupled to each other and one-body molded four cavitys 3 of formation between annular outer wall 1 and supporting walls 2 with supporting walls 2.Because the inside of internal mold main body 5 is provided with cavity, employed polystyrene raw material significantly reduces when making this bridge internal mold, and saving material reaches more than 40%, therefore, has reduced manufacturing cost, has avoided raw-material waste.Lateral surface at annular outer wall 1 is provided with back-up coat 6, and the weight capacity that back-up coat 6 helps to improve internal mold main body 5 is set.Back-up coat 6 comprises adhesive layer and grid cloth 4 in the present embodiment, cementing agent is sprayed between the lateral surface of grid cloth 4 and annular outer wall 1 during enforcement, make the lateral surface strong bonded of grid cloth 4 and annular outer wall 1, for the purpose of clear expression, in the accompanying drawing grid cloth 4 in the indication position for opening state, during use, the lateral surface of grid cloth 4 and annular outer wall 1 is attached to together fully.Described grid cloth 4 adopts the grid cloth of glass fiber material.During use, be provided with the reinforced rail screen net structure around the bridge internal mold, concrete-filled steel muscle wire gauze structure also contacts with the outside of the annular outer wall 1 of bridge internal mold, because annular outer wall 1 lateral surface is provided with the grid cloth 4 of glass fiber material, therefore improved the adhesion stress of concrete and bridge internal mold main body 5.When building bridge construction, the bridge internal mold needs certain weight capacity, because the plastic foam material of the lightweight that internal mold main body 5 adopts, and inside is provided with cavity, therefore, weight capacity certainly will descend to some extent, and can improve the weight capacity of bridge internal mold integral body in the grid cloth 4 of annular outer wall 1 lateral surface sticking glass fiber material, thereby the building of structure that helps bridge improved the efficient and the quality of engineering construction.Obviously; concrete size and construction requirement according to different bridge constructions; the size of internal mold main body 5 can be adjusted; constitute annular outer wall 1, the supporting walls 2 of internal mold main body 5; and the shape and the quantity of annular outer wall 1 and supporting walls 2 cavity that surrounds also can be adjusted as the case may be; but all be the replacement that is equal to, still be included within the protection domain of the present utility model the present embodiment technical scheme.Adopt the bridge internal mold of present embodiment to help reducing cost, reduce the wasting of resources, be widely used in the engineering construction project of bridge on highway and different types of rridges.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
