Abstract
The invention provides a kind of Novel silica gel composite flexible interface, this flexible interface comprises overcoat interface portion, interpolation interface portion, multiple annular protrusion, and this flexible interface also comprises multiple zinc-plated iron core circle, the recess of described zinc-plated iron core circle between annular protrusion; The present invention can not only solve bridge and cause the problem on deformation of pipeline and the problem of aging of pvc pipe because temperature deformation produces displacement, and bridge draining can be made again unobstructed.
Description
Technical field:
The invention belongs to building material field, be specifically related to a kind of rain pipe silica gel composite and flexible interface of bridge.
Background technology:
In the drainage system of current China urban viaduct bridge floor, the drainage pipe laid in the bridge construction of top must be in mating connection with the gutter (being generally pvc pipe) that arranges on bridge pier.Because bridge is by influence of temperature change, the elongation of bridge and contraction produce relative displacement between making between girder and bridge pier, therefore, are laid at the bottom of beam respectively and the connection demand fulfillment displacement of the pipeline at Dun Ding place and the unobstructed requirement of draining.
At present conventional type of attachment makes upper and lower pipeline rigid connection, relies on the flexural deformation of pipeline to adapt to the relative displacement between beam and pier, but be not suitable for the situation of laying and being connected with pier shaft interior conduit in beam body and there is the problem that anchor tip is difficult to maintenance.Another kind of common type of attachment is for arrange a funnel at pier push pipe road opening part, and deeply wherein, this set can make the spacing between upper pipe and hopper walls can meet the requirement of aforementioned relative displacement to upper pipe.
Summary of the invention:
The object of the invention is to be to provide that one can meet bridge temperature sex change requirement, resisted shrinkage is out of shape and have necessarily anti-aging, tensile strength characteristics, and leakproof can be ensured and be convenient to the flexible interface of maintenance.
According to above-mentioned purpose, the invention provides a kind of silica gel composite and flexible interface, this flexible interface comprises overcoat interface portion, interpolation interface portion, multiple annular protrusion, and this flexible interface also comprises multiple zinc-plated iron core circle, 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 ratio of described silica gel and glass is 1:1;
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 defaulted in bridge, and described interpolation interface portion is inserted in the opening of the bottom water pipe defaulted in bridge pier;
Further, the hot strength of described flexible interface is 4.47Mpa.
The invention has the beneficial effects as follows that the present invention can not only solve bridge and cause the problem on deformation of pipeline and the problem of aging of pvc pipe because temperature deformation produces displacement, bridge draining can be made again unobstructed.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of flexible interface of the present invention;
Fig. 2 is flexible interface connection diagram of the present invention.
Detailed description of the invention:
As shown in Figure 1, for a kind of silica gel composite and flexible interface of the present invention, this flexible interface comprises overcoat interface portion 1, interpolation interface portion 2, multiple annular protrusion 3 and multiple zinc-plated iron core circle 4, wherein the recess of zinc-plated iron core circle 4 between two annular protrusions 3.
Overcoat interface portion 1, interpolation interface portion 2 and annular protrusion 3 adopt silica gel glass fiber material to be composited, wherein silica gel is natural silica gel, glass adopts aviation special glass fiber, and the composition of silica gel and glass respectively accounts for 50% (mass percent), forms through high temperature 180 DEG C of compactings.
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 is with the diameter of overcoat interface portion 1 and interpolation interface portion 2, and be also 150-300mm, the length of each annular projection 3 is 20mm, can be used for the shrinkage and the extensibility that increase flexible interface; Zinc-plated iron core circle 4 can increase the fastness of product, for extending the application life of flexible interface.
As shown in Figure 2, in use, described overcoat interface portion 1 is enclosed within outside the opening of the top water pipe 6 (pvc pipe) defaulted in bridge 5, described interpolation interface portion 2 is inserted in the opening of the bottom water pipe 8 defaulted in bridge pier 7, and the inserting place of interface portion and water pipe can be coated with appropriate adhesive.
The silica gel adopted due to the main part of this flexible interface and glass are composited, and its performance test results is as shown in table 1, and it is more superior than adopting the performance of elastomeric material to adopt this material.
| Interventions Requested | Test result |
| Resistance to impact (100cm) | Specimen surface flawless, wrinkle and peeling phenomenon |
| Hardness (Shao A) | 53 |
| Low-temperature bending (-30 DEG C, 1h) | Sample is flawless-30 DEG C time |
| Hot strength (Mpa) | 4.47 |
| Anti-aging (500h-5wh) | Specimen surface is unchanged |
In sum, bridge provided by the invention with the flexible joint of rainwater pvc pipe connect drainage pipe, adopt annular projection due to it and adopt material silica gel composite, when making pipeline produce displacement because of bridge temperature deformation, while making critical point keep circular cross-section, also can there be larger axial compression and elongation 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 present invention can not only solve bridge because of temperature deformation produce displacement cause the problem on deformation of pipeline and the problem of aging of pvc pipe, bridge draining can be made again unobstructed.
Above-mentioned detailed description is illustrating for embodiments possible of the present invention, and above-mentioned embodiment is also not used to limit the scope of the claims of the present invention, all do not depart from of the present invention equivalence implement or change, the scope of the claims of the present invention all should be contained in.
