Abstract
A three-proofing telescopic device for bridge is used for building and repairing bridge expansion joint. The composite asphalt pavement structure mainly comprises a covering layer, a sliding layer and a framework, wherein the covering layer is composed of a composite asphalt paving plate [13] containing two layers of synthetic fiber grids [11] and [12], a sliding plate [10] is arranged below the covering layer, a cover plate [9] is arranged below the sliding plate [10], the cover plate [9] can slide along with the expansion and contraction of a bridge, and waterproof layers [8] are arranged on two sides of the cover plate [9 ]. The device can better solve the problem of anti-seepage corrosion, is vibration-resistant and low in noise, can meet the three-proofing requirement through tests, has wider functionality and sociality, and can meet the functional requirements of expressways and urban bridges.
Description
A kind of three anti-stretching devices that relate to bridge are used for setting up and keeping in repair of bridge, belong to bridge member.
Because the length travel and the corner of the bridge end that variations in temperature and vehicle ' cause, stretching device is absolutely necessary.But the ingredient of stretching device is big especially with connected asphalt pavement stiffness differences as steel, rubber tile, concrete etc., thus usually produce the bigger step discrepancy in elevation at shrinkage joint place, cause vehicle by the time shock and vibration, produce very big noise.Simultaneously, near the bridge deck the shrinkage joint and the layer of mating formation also often damage therefrom and have to repair, even rainwater is along oozing heavy corrosion stretching device main component and beam undersetting under the crack.In addition, the step discrepancy in elevation also causes passenger's uncomfortable sensation, the unnecessary damage of vehicle, the increase of goods packing expense.Existing shrinkage joint technology does not possess functional widely and social that bridge itself at first should possess, and more can not satisfy the requirement of present speedway and Urban Bridge development.Therefore, the new stretching device of exploitation is one of the most critical problem of current bridge erection and maintenance.
In view of this, the purpose of this utility model just is to provide a kind of energy vibration proof, antinoise, etch-proof bridge three anti-stretching devices.
The utility model is processed into combined frame with the steel member, skeleton is embedded be mixed with in the concrete slab of steel fibre, on skeleton, cover a stainless steel cover plate, at cover plate, both sides at cover plate are provided with waterproofing course, lay the polytetrafluoroethylene (PTFE) slide plate of a molded breadth on the cover plate.On slide plate, lay the composite asphalt contain two-layer synthetic fibers grid or the synthetic resin grid plate of mating formation.Below in conjunction with accompanying drawing and example in detail, operating principle of the present utility model and architectural feature are described in detail.
Description of drawings
Accompanying drawing is the utility model transverse sectional view.
Referring to accompanying drawing, the utility model mainly is made up of covering layer, sliding layer, skeleton three parts.Main member comprises that skeleton base plate ［ 1 ］, base plate ［ 2 ］, floor ［ 3 ］, dowel ［ 4 ］, bridge deck ［ 5 ］, comb plate, comb joint ［ 6 ］, broach ［ 7 ］, waterproofing course ［ 8 ］, cover plate ［ 9 ］, sliding panel ［ 10 ］, fiber web layer ［ 11 ］, ［ 12 ］, composite asphalt are mated formation layer ［ 13 ］, beam body ［ 14 ］ constitutes.Base plate ［ 1 ］ steel plate, base plate ［ 2 ］ is a unequal angle, according to the amount of contracting calculating second month in a season angle steel model, it and base plate are welded into one, along the angle steel length direction every 250～300 millimeters weldering floors ［ 3 ］, simultaneously every the reinforcing bar of a φ 16～20 of 250～300 millimeter weldering as dowel ［ 4 ］, dowel ［ 4 ］ is arranged with floor ［ 3 ］ stagger arrangement, one end of dowel ［ 4 ］ is welded on the base plate ［ 2 ］, and inserts in the bridge deck ［ 5 ］.The whole skeleton that is made of member ［ 1 ］, ［ 2 ］, ［ 3 ］, ［ 4 ］ is flush-mounted in the concrete slab ［ 5 ］ that is added with steel fibre, the top of skeleton welding comb plate, comb joint ［ 6 ］, and bridge is strengthened with bolt factually.Comb plate, comb joint ［ 6 ］ is a steel plate, and its thickness is determined by supporting capacity, is processed with broach ［ 7 ］ at the seam end, and comb plate, comb joint ［ 6 ］ is configuration in pairs, and wrong friendship of broach ［ 7 ］ arranged, according to calculating decision seam construction gap.
Be coated with a stainless steel cover plate ［ 9 ］ on the seam crossing of comb plate, comb joint ［ 6 ］, its thickness is about 1 millimeter, and its width is about 1.5～2 times of bridge stroke.Cover plate ［ 9 ］ welds with one side of comb plate, comb joint ［ 6 ］, can follow the bridge telescopic moving down at polytetrafluoroethylene (PTFE) slide plate ［ 10 ］, and there is waterproofing course ［ 8 ］ both sides of cover plate ［ 9 ］, and the material of waterproofing course can be made of different materials as required.The top of cover plate ［ 9 ］ is sliding panel ［ 10 ］, and sliding panel ［ 10 ］ is made by polytetrafluoroethylene (PTFE), and the B value is by calculating decision.The one side that contacts with cover plate ［ 9 ］ is a shiny surface, be convenient to cover plate ［ 9 ］ and freely stretch down at it, the one side that contacts with composite asphalt plate ［ 14 ］ is a matsurface, is convenient to the combination of composite asphalt plate ［ 14 ］, so-called sliding panel reality is not slided, but the slip of cover plate ［ 9 ］.
Covering layer is made up of the composite asphalt that the contains two-layer synthetic fibers grid plate of mating formation.Synthetic fibers grid or synthetic resin grid can be made by propylene, nylon, vinylon, polypropylene, and laying length is calculated by A+B+C to be decided.Synthetic fibers grid ［ 11 ］, ［ 12 ］ position in composite asphalt is mated formation plate ［ 13 ］ are respectively: D is that 36 millimeters, E are that 18 millimeters, F are 18 millimeters.Since the combined effect of the bullet flow shape of the crack peptizaiton that grid rose, the extension ability of grid itself and asphalt pavement plate, the continuity and the ride comfort of mating formation continuously and having ensured bridge floor fully at deck expansion joint place.Simultaneously, the body abutment member at shrinkage joint directly is not subjected to the vehicular impact effect.This installs whole members and is supported by beam body ［ 14 ］.
The utility model can satisfy three and prevent requirements through test, has functionally widely and social, can satisfy the functional requirement of speedway and Urban Bridge.
