Abstract
An updated type durable, waterproof, dustproof and shockproof elastic device, which relates to an elastic device used on road, large square and bridge. The elastic device comprises a fixing comb-tooth steel plate, a stainless steel sliding layer that can move on and below the comb-tooth steel plate, a waterproof rubber layer and an anti-wearing rubber layer. Comb-tooth elastic part of the flexible comb-tooth steel plate is on a bridge surface without expansion joint on one side of bridge joint, a slag discharge flume is provided at the root of tooth seam. Two comb-tooth steel plates are anchored on a bridge abutment or a beam body by anchor bolts, foreign object or dust in the expansion joint can not enter the position between the fixing comb-tooth steel plate and the stainless steel sliding plate basically, and the comb-tooth steel plate makes no tilting or exposition caused by rotation under external force; vertical meshing is made between the fixing comb-tooth steel plate and the stainless steel sliding plate, which are kept on the same level. Steel plate stripes are laid under rear row of the flexible comb-tooth steel plate, two ends of the flexible comb-tooth steel plate are kept on the same level, early fatigue of anchor bolt is avoided. The utility model has flat surface, comfortable and safe driving, strong impact resistance and long operational life.
Description
Technical field the utility model relates to the stretching device that uses on a kind of road, large-scale square, the bridge.
Background technology is present, and existing stretching device is divided into: dock steel plate tooth plate type, sheet pack mould assembly, board-like rubber-type, modulus formula, several big classes of seamless stowing formula." non-shock bridge expansion joint " (number of patent application 01133500.9), " novel road is durable, waterproof, dustproof, anti-quaking telescopicing device " (patent No. 97241688.9) and " a kind of bridge comb shape steel plate three anti-stretching devices " (patent No. 00259252.5) all be steel comb template shrinkage joint, it is smooth to have road surfaces, ride comfort, shallow embedding, structure height is low, advantages such as cost is low, but exist the weld bond of comb tooth plate to snap, the monoblock steel plate comes off, the anchoring piece weakness causes loosening, foreign material easy-clear not in the slit, lose Telescopic, be difficult to guarantee that tooth plate and backing plate are fitted and the generation gap, stressed unfavorable to connecting portion, thereby cause noise, jump car, day and night operation in addition, tooth plate is under course under cyclic loading, cause premature fatigue, fastening bolt (or screw) is loosening, broach rotates perk and exposes, foreign material will be combed the gap easily and block, and influence is flexible.
The summary of the invention the purpose of this utility model is at above-mentioned present situation, aim to provide a kind ofly provide a kind of broach not to be prone to rotate perk, expose, anchoring piece is loosening and monoblock steel plate dropping situations, the modified of surfacing, the comfortable safety of driving a vehicle, anti-impact force is strong, the life-span is long stretching device is durable, waterproof and dustproof, anti-quaking telescopicing device.
The implementation of the utility model purpose is, modified is durable, waterproof and dustproof, anti-quaking telescopicing device, comprises fixed fingers steel plate 1, active comb steel plate steel plate 2.The broach telescopic section of active comb steel plate steel plate 2 is located at joint of bridge one side not to be had on the bridge floor at shrinkage joint, pouring PVC ointment 14 in the flexible gap of comb shape steel plate broach, and the slot root is provided with the deslagging skewed slot.The broach front end of comb shape steel plate is provided with downward-sloping crashproof slope, and lining one deck stainless steel was slided layer 3, water proof rubber layer 4, abrasionproof rubber layer 5 under bridge expanssion joint one side had the flexible comb shape steel plate of broach.Fixed fingers steel plate 1, active comb steel plate steel plate 2 are anchored at abutment or Liang Tishang with anchor bolt 6,10 respectively, and two three-dimensional interlocks of broach steel plate keep at grade.
The utility model fixed fingers steel plate 1, active comb steel plate steel plate 2 are anchored at abutment or Liang Tishang with anchor bolt 6,10 respectively, make between the sliding layer 3 of fixed fingers steel plate 1 and stainless steel very close to each other, thereby the impurities and dust in the shrinkage joint can not be entered between fixed fingers steel plate 1 and the sliding layer 3 of stainless steel, and the broach steel plate can not expose in stressed rotation perk.
Anchor bolt 6,10 adopts locking lock bolt, and it is loosening that fastening bolt is difficult for.Insert sulphide mastic between anchor bolt 6,10 and the anchor bolt hole, make anchoring more firm.
At the thick steel plate bar 15 of active comb steel plate steel plate 2 back row anchor bolt 6 underlay one deck 1-2mm, the two ends of active comb steel plate steel plate 2 are ridden on the steel plate bar 15, rear end and front end broach are on same horizontal plane, can be not stressed because of the empty paddy part in the middle of the active comb steel plate steel plate, vehicle is formed when crossing shoulder rod principle, the long-term premature fatigue that can cause anchor bolt after stressed.As not adding steel plate bar 15, the front end braces of active comb steel plate steel plate 2 is on the sliding layer 3 of the stainless steel on the another side of shrinkage joint, the sliding layer of stainless steel 3 thick 1-2mm, the concrete of both sides, the shrinkage joint layer of mating formation can differ 1-2mm up and down because of the sliding layer 3 of stainless steel, mid portion becomes sky paddy on the sliding layer 3 of stainless steel, vehicle is formed when crossing active comb steel plate steel plate 2 shoulder rod principle, the long-term stressed premature fatigue that causes anchor bolt.
