Abstract
The utility model provides a novel silica gel composite flexible joint. The flexible joint comprises an external sleeving port part, an internal plugging port part and a plurality of annular protuberances; the flexible joint further comprises a plurality of galvanized iron core rings which are located in depressions among the annular protuberances. The novel silica gel composite flexible joint can not only solve the problems that the pipeline is deformed due to the fact that a bridge is deformed to produce displacement for temperature and a PVC (Polyvinyl Chloride) pipe is aged, but also enable the bridge drainage to be unobstructed.
Description
Technical field:
The utility model belongs to building material field, is specifically related to the rainwater pipe silica gel composite and flexible interface that a kind of bridge is used.
Background technology:
At present in the drainage system of China's urban viaduct bridge floor, the drainage pipe of laying in the bridge construction of top must matching be connected with the gutter (generally being pvc pipe) that arranges on the bridge pier.Because bridge is subjected to influence of temperature change, the elongation of bridge and contraction produce relative displacement between can making between girder and the bridge pier, therefore, are laid on respectively at the bottom of the beam and being connected of pipeline at Dun Ding place need satisfy displacement and the unobstructed requirement of draining.
Type of attachment at present commonly used is to make the rigid connection of pipeline up and down, and the flexural deformation that relies on pipeline to be adapting to the relative displacement between beam and the pier, but is not suitable for situation about being connected with the pier shaft interior conduit in the beam body and the problem that exists anchor tip to be difficult to overhaul of laying.Another kind of common type of attachment is for to arrange a funnel at pier push pipe road opening part, upper pipe deeply wherein, this set can make the spacing between upper pipe and hopper walls can satisfy the requirement of aforementioned relative displacement.
The utility model content:
The purpose of this utility model is to be to provide a kind of can satisfy bridge temperature sex change requirement, anti-shrinkage strain and have necessarily anti-aging, tensile strength characteristics, and can guarantee leakproof and the flexible interface of being convenient to maintenance.
According to above-mentioned purpose, the utility model provides a kind of novel silica gel composite and flexible interface, this flexible interface comprises overcoat interface portion, interpolation interface portion, a plurality of annular protrusion, and this flexible interface also comprises a plurality of zinc-plated iron core circles, the recess of described zinc-plated iron core circle between annular protrusion;
Further, described overcoat interface portion, interpolation interface portion and annular protrusion adopt silica gel and glass to be pressed into one;
Further, the diameter of described overcoat interface portion and interpolation interface portion is 150-300mm, and the length of described flexible interface is 450mm, and thickness is 6mm;
Further, the length of each annular projection is 20mm;
Further, described overcoat interface portion is enclosed within outside the opening of the top water pipe that defaults in the bridge, and described interpolation interface portion is inserted in the opening of the bottom water pipe that defaults in the bridge pier;
The beneficial effects of the utility model are that the utility model can not only solve bridge because temperature deformation generation displacement causes the problem on deformation of pipeline and the problem of aging of pvc pipe, can make the bridge draining unobstructed again.
Description of drawings:
Fig. 1 is the structural representation of the utility model flexible interface;
Fig. 2 is the utility model flexible interface connection diagram.
The specific embodiment:
As shown in Figure 1, be a kind of silica gel composite and flexible interface of the present utility model, this flexible interface comprises overcoat interface portion 1, interpolation interface portion 2, a plurality of annular protrusion 3 and a plurality of zinc-plated iron core circle 4, the wherein recess of zinc-plated iron core circle 4 between two annular protrusions 3.
The diameter of overcoat interface portion 1 and interpolation interface portion 2 is 150-300mm, and the length of flexible interface is 450mm, and thickness is 6mm; The diameter of annular projection 3 also is 150-300mm with the diameter of overcoat interface portion 1 and interpolation interface portion 2, and the length of each annular projection 3 (highly) is 20mm, can be used for increasing shrinkage and the extensibility of flexible interface; Zinc-plated iron core circle 4 can increase the fastness of product, is used for prolonging the application life of flexible interface.
As shown in Figure 2, in use, described overcoat interface portion 1 is enclosed within the top water pipe 6(PVC pipe that defaults in the bridge 5) opening outside, described interpolation interface portion 2 is inserted in the opening of the bottom water pipe 8 that defaults in the bridge pier 7, the slotting place of the cover of interface portion and water pipe can be coated with an amount of adhesive.
Because silica gel and glass that the main part of this flexible interface adopts are composited, its performance test results is as shown in table 1, adopts this material more superior than the performance that adopts elastomeric material.
| Interventions Requested | Test result |
| Resistance to impact (100cm) | Specimen surface flawless, wrinkle and peeling phenomenon |
| Hardness (Shao A) | 53 |
| Low-temperature bending (30 ° of C, 1h) | Sample is flawless when-30 ° of C |
| Hot strength (Mpa) | 4.47 |
| Anti-aging (500h-5wh) | The specimen surface no change |
In sum, the rainwater pvc pipe flexible joint that the bridge that the utility model provides is used connects drainage pipe, because it adopts annular projection and adopts material silica gel composite, make when pipeline produces displacement because of the bridge temperature deformation, when making the critical point keep circular cross-section, also bigger axial compression and elongation can be arranged when mounted; Wherein the fatigue resistance of material silica gel composite, corrosion resistance and elasticity etc. have unrivaled superiority; Zinc-plated iron core circle can also increase the fastness of product.Therefore the utility model can not only solve bridge because temperature deformation generation displacement causes the problem on deformation of pipeline and the problem of aging of pvc pipe, can make the bridge draining unobstructed again.
Above-mentioned detailed description is specifying at embodiments possible of the present utility model, above-mentioned embodiment is not in order to limit claim of the present utility model, allly do not break away from that equivalence of the present utility model is implemented or change, all should be contained in claim of the present utility model.
