Abstract
The utility model belongs to an air bag inner mold for bridge reinforcement. The air bag inner mold comprises an inner side mold. The two ends of the inner side mold are provided with end molds respectively. A hollow structure is formed by the inner side mold and the end molds jointly. The end molds are communicated with the interior of the inner side mold. A valve is arranged on the inner side mold. The inner side mold is externally in a cuboid shape or a cylinder shape. The component sectional area can be effectively increased by pouring self-leveling vibration-free concrete, construction is convenient, the reinforcement effect is better compared with a traditional reinforcement method, and meanwhile the reinforcement cost is saved; the reinforcement requirements for structures of different types can be met by adjusting the sections and sizes of the end molds.
Description
Technical field
The utility model belongs to Technology Bridge Strengthening field, is specifically related to a kind of bridge strengthening Air bag inner model.
Background technology
Thin-walled hollow structure, as case beam, hollowcore slab etc. often occur various cracks in process under arms, causes structural bearing capacity to decline; Adopt Enlargement of Section can effectively improve its supporting capacity and rigidity, but adopt Enlargement of Section reinforce time conventionally need to set up template at external surface of structural member, complicated construction technique, difficulty is larger, consolidation effect be also difficult to ensure; And for hollow slab bridge, because hinge seam size is little, the general thickness by increase hollowcore slab top board improves bearing capacity, this method is difficult to bring into play the advantage that Enlargement of Section is reinforced.
Utility model content
The purpose of this utility model is to provide the bridge strengthening Air bag inner model that a kind of simple structure, cost are lower, be convenient to strengthening construction.
For achieving the above object, the technical solution adopted in the utility model is, a kind of bridge strengthening Air bag inner model, comprise interior side form, the two ends of interior side form are respectively equipped with end mould, and interior side form forms hollow structure jointly with end mould, end mould and interior side form internal communication, be provided with valve in internal membrane; The external shape of described interior side form is cuboid or cylinder.
The external shape of described end mould can be cuboid or spheroid.
End mould of the present utility model adopts sewing or barbola work to be connected with interior side form, and after Air bag inner model inflation, depended on pressure gas bears the pressure of rear pouring concrete.
Described end mould cross section is circular, rectangle or trapezoidal, is determined by strenthening member interior shape, and end mould cross dimension is consistent with strenthening member inside dimension, inflates rear and former member inwall laminating closely.
Described interior side form cross section is rectangle or circle, and area of section is determined by strengthening member design, holds mould and interior side form area of section poor for reinforcing the sectional area increasing.
The material of described described Air bag inner model is rubber, plastics or cloth.
Implementation step of the present utility model is as follows: adopt this Air bag inner model in bridge construction in as strengthening members such as little case beam, hollowcore slabs, at the top drilling of hollow strenthening member, Air bag inner model is arranged in and reinforces position, Air bag inner model is inflated to control air pressure; Sprayed mortar interfacial agents, moistening hollow strenthening member inwall, builds Self-leveling and exempts from vibration concrete; Repair top board hole, to complete reinforcing.
The beneficial effect that the utility model produces is that the material of Air bag inner model can adopt rubber, cloth or plastic or other material, draws materials various, holds mould and interior side form to adopt sewing or barbola work to be connected, easy to make; When Air bag inner model application, only need be placed in component inside at original structure openings in the ceiling, then inflation is used, exempt from vibration concrete and can effectively increase member section area by building Self-leveling, easy construction, compared with traditional reinforcement means, consolidation effect is better, saves reinforcement cost simultaneously; Can hold mode cross section and size by adjustment, meet the reinforcing needs of dissimilar structure.

Detailed description of the invention
Embodiment 1
As Figure 1-3, a kind of bridge strengthening Air bag inner model, comprises interior side form 1, and the two ends of interior side form 1 are respectively equipped with end mould 4, and interior side form 1 and the common dumbbell shape hollow structure that forms of end mould 4, be provided with valve 2 in internal membrane 1.
The concrete implementation step that adopts described bridge strengthening with Air bag inner model, prefabricated concrete hollow slab to be reinforced is as follows: step (1), make reinforcing Air bag inner model, Air bag inner model length 3.0m, end mould 4 is cuboid, B-B profile cross-section in Fig. 2 is of a size of wide 1.25m × high 0.997m, the external shape of internal membrane 1 is cuboid, and the sectional dimension of internal membrane 1 is wide 0.8m × high 0.6m; Step (2), forms hole 3 at hollowcore slab 2 top drillings, and Air bag inner model is arranged in and reinforces position; Step (3), Air bag inner model is inflated to control air pressure; Step (4), sprayed mortar interfacial agents, moistening hollow strenthening member, builds Self-leveling and exempts from vibration concrete, and carries out maintenance, forms layer of concrete 5; Step (5), repairs hollowcore slab top 2 holes 3, to complete reinforcing, completes the structure of the strenthening member after reinforcing as shown in Fig. 4-5.
Embodiment 2
Embodiment 2 is with the difference of embodiment 1, and the external shape of interior side form 1 is cylinder, and the B-B sectional schematic diagram of Air bag inner model as shown in Figure 6; Adopt the strenthening member A-A sectional schematic diagram of Air bag inner model in embodiment 2 as shown in Figure 7.
It should be noted that at this, the utility model not only can be used for reinforcement bridge structure, as tunnel etc., also can directly adopt the utility model to increase member thickness at civil engineering other field; The technical scheme of every employing structure design principle of the present utility model, by arrange the technical measures of air bag ruggedized construction at component inside, all should be within protection domain of the present utility model.
