Abstract
The utility model disclosing a permanent inner core construction template used in a concrete box girder in the bridge project construction consists of a template unit which is a thin concrete shell and provided with reinforcement and a steel wire mesh. As the utility model forms the template unit by mixing the steel wire mesh, reinforcement and the concrete, the utility model has the advantages of light weight, thin thickness and easy construction. The utility model has high stiffness and strength, thus ensuring the shape and size of the inner core of a bridge and after the construction, the utility model which can be used as a protection coating of the concrete box girder, thus improving the bridge construction efficiency and lowering the construction cost is good for bridge construction.
Description
One, technical field
The utility model relates to the working construction formwork of bridge engineering, especially relates to the permanent inner core construction formwork of concrete box girder.
Two, background technology
In the bridge engineering construction, because the box-girder inner space is little, the inner core formwork for placing is removed very difficult, and especially in the cast-in-place construction of Curved Continuous, oblique overpass bridge, interior core mold plate can't be removed at all.Solution at this technical problem is to utilize air bag, paper pulp template at present, even adopts the coarse wicker basket of processing as interior core mold plate.The disadvantage of above-mentioned template is that the rigidity of template own is little, and the accurately shape and the size of guard box beam inner core also can't be guaranteed the thickness of protection tier and the quality of concrete structure.
Three, technical scheme
Technical problem: the utility model provides a kind of permanent inner core construction formwork of concrete box girder that helps bridge construction.
Technical scheme: the utility model is a kind of permanent inner core construction formwork of concrete box girder that is used for the bridge engineering construction, is made up of modular unit, and modular unit is a concrete shell 1, is provided with reinforcement and gauze wire cloth 3 in concrete shell 1.
Beneficial effect: 1. because the utility model is to utilize gauze wire cloth, reinforcement and concrete to mix to form modular unit, so the advantage of the lightweight of the utlity model has, thin thickness is convenient to construction; And rigidity of the present utility model is big, and the intensity height can be guaranteed the shape and size of bridge inner core; after the construction, the utility model can be used as the topping of concrete box beam steel, improves the efficient of bridge construction; reduce construction cost, so the utility model helps bridge construction.2. the technical measures of the gauze wire cloth that is provided with of the vertical, horizontal reinforcement taked of the utility model and upper and lower thereof, make the utility model on the basis about 3 centimetres, have enough intensity in its controllable thickness, make its both fully guard box beam core shape and accuracy of gauge, can keep the advantage of lightweight, shell again.3. the utility model can link into an integrated entity a plurality of modular units according to the case beam length, forms a complete template.
Four, description of drawings
Fig. 1 is the case beam construction figure that contains template described in the utility model.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is a cross-sectional drawing of the present utility model.
Fig. 4 is structural reinforcement figure of the present utility model.
Fig. 5 is a modular unit joint construction schematic diagram of the present utility model.
Five, embodiment
The utility model is a kind of permanent inner core construction formwork of concrete box girder that is used for the bridge engineering construction, form by modular unit, modular unit is a concrete shell 1, in concrete shell 1, be provided with reinforcement and gauze wire cloth 3, the utility model can be provided with the composite steel silk screen, in the present embodiment, reinforcement is made up of vertical reinforcement 21 and transversal reinforcement 22, gauze wire cloth 3 is located at the top of reinforcement, below reinforcement, also be provided with another gauze wire cloth 4, the utility model can link together a plurality of modular units according to the length of case beam to be constructed, and present embodiment adopts following technique measures that modular unit is coupled together; Concrete measure connects by epoxy resin between the modular unit for to be provided with connector 11 on modular unit, and fastening by bolt 51 that passes connector 11 and nut 52.
