Description
The utility model relates to a kind of waterproof and dustproof, anti-quaking telescopicing device that is used for various Highway Bridge Expansion Joint place.
Butt type expansion installation, rubber stretching device are adopted in short span highway bridge shrinkage joint in the past, to adopting cast steel comb shape stretching device than the long span road bridge, leak, leak lime-ash, problem such as not shockproof more no matter which kind of device all exists to some extent.For addressing these problems, I have designed " road bridge waterproof and dustproof, anti-quaking telescopicing device " (patent No. 28100736.6, day for announcing 900704).It comprises the waterproofing course 4 that is laid on the seam crossing bridge deck, the abrasionproof backing plate 3 on it and the comb shape on the road surface steel plate 1,2 that stretches.The broach telescopic section of the flexible steel plate 1,2 of comb shape is located at joint of bridge place one side not to be had on the bridge floor at shrinkage joint 14, and its broach seam root is provided with deslagging skewed slot 6.Though it has excellent waterproof, dustproof, shock resistance because waterproofing course 4 is laid immediately on the coarse concrete cushion of bridge floor, waterproofing course the high-speed overload vehicle repeat roll with rubbing action under, worn out gradually and leak by the point grain of bed course and tape edge corner angle.The flexible steel plate broach top of comb shape arris is the minimum circular arc of radius in addition, and when the bridge beam-ends produced corner reciprocal or construction error, the crashworthiness of broach end was undesirable, influences shockproof effect.
The purpose of this utility model is the deficiency that exists according to above-mentioned stretching device, is intended to design a kind of waterproof and dustproof, shockproof properties is better, long-lived road bridge stretching device.
The purpose of this utility model realizes in the following manner, and a kind of road bridge is durable, waterproof and dustproof, anti-quaking telescopicing device, and it comprises waterproofing course 4, abrasionproof backing plate 3, and the flexible metal sheet 1,2 of comb shape.The broach telescopic section of comb shape metal sheet is located at joint of bridge one side not to be had on the bridge floor at shrinkage joint 14, and broach seam root is provided with deslagging skewed slot 6, have below the skewed slot gradient 1=1:1-2, waterproofing course 4 be laid on the seam crossing bridge floor "
" shape metal sheet overcoat 5, the bottom recess stretches in the shrinkage joint, and waterproofing course is spread thereon, and the flexible metal sheet broach front top of comb shape is provided with downward-sloping crashproof slope 7.
"
" shape metal sheet overcoat adopts has good anti-corrosion elastic metallic panel material, as galvanized steel plain sheet or copper coin etc.Thickness of slab 0.5-1.5mm plays support, protection and the effect of reinforcement waterproofing course.
The nonmetal elastic water-proofing material of waterproofing course recess at shrinkage joint fills up jam-pack as sponge or foamed plastics etc., has stopped the ponding in the shrinkage joint, contamination.
The utility model content is described in detail in detail with reference to the accompanying drawings.
Fig. 1 stretching device I-I sectional drawing
Fig. 2 stretching device II-II sectional drawing
Fig. 3 the utility model plan view
Fig. 4 broach front top structural representation
With reference to accompanying drawing, the utility model adopts CN
100736.6 the job practices construction, 11 for fixing the anchor bolt of this stretching device among the figure."
" shape Thin Elastic metal sheet 4 is laid on the seam crossing bridge floor, above be waterproofing course, avoided waterproofing course directly to contact with the coarse concrete cushion of bridge floor, the protection waterproofing course does not does not wear and tear, and has strengthened the waterproofing course durability. Flexible metal sheet 1,2 surfaces of metal sheet 5 and comb shape are coated with high-quality corrosion protection wear-resistant paint, have strengthened barrier propterty, have increased durability.
The width of abrasionproof backing plate 3 is as the criterion with the edge that the backing plate front end can reach bridge expanssion joint 14.The upper and lower corner angle of abrasionproof backing plate front end are worn into circular arc, prevent the wearing and tearing to comb shape steel plate bottom, waterproofing course.
Shrinkage joint between the flexible steel plate broach of comb shape is greasy flat with plastic ointment or polyvinyl chloride (PVC) cement sealing, generally speaking, water, dust can not enter from the broach shrinkage joint, even just in case enter, then the flexible steel plate of comb shape will be expelled to the foreign material that enter outside the shrinkage joint by deslagging skewed slot 5 by means of the dilatation of bridge.
The flexible metal sheet upper front end of comb shape is provided with downward-sloping crashproof slope, and its gradient 1=1:20-30 has improved the shockproof properties that installs, and makes driving steadily, does not jump the car phenomenon.
Waterproofing course adopts the weather-proof anti-corrosion non-metallic elastic material of high-quality, as ethylene propylene diene rubber, chloroprene rubber material.
The utility model is simple in structure, good with the rigid pavement integral rigidity, have fabulous waterproof and dustproof, shockproof properties, the driving comfort is good, durable in use, be 30-50 times of ordinary rubber stretching device application life more than 50 years, and cost is only reined in 1/15 of road bridge stretching device for West Germany's hair that China introduces.The different types of rridges that the utility model is suitable for various different spans, different-thickness, different constructional materialss use, and are current ideal road bridge stretching devices both at home and abroad.Require to have under the development trend of equal service life application life at current bridge stretching structure and bridge, this road bridge stretching device has vast potential for future development.
