Abstract
The utility model discloses a falling-off prevention cantilever-type comb-formed retractable device, which comprises two comb-formed steel plates and two anchor plates, wherein the comb-formed steel plates are fixed the T-shaped anchor plates in the cantilever type. The device is characterized in that a falling-off prevention baffle plate is arranged under a cantilever of one comb-formed steel plate, the cross section of the baffle plate takes the L shape, and the two sides of the baffle plate are respectively and fixedly connected with the comb-formed steel plates and the anchor plates; a falling-off prevention baffle plate is arranged under a cantilever of the other comb-formed steel plate, the cross section of the baffle plate takes the L shape and is provided with reinforced rib plates, a gap is leaved between one side of the baffle plate and the comb-shaped steel plate, and the other side thereof is fixedly connected with the anchor plates; and the comb teeth of the two comb-formed steel plates are slidingly connected with the two baffle plates in a spigot and socket way. The device has simple structure and convenient construction; compared with the prior art, the device has the advantages that the rubbish does not fall into a rubber water stop, the water can be discharged more freely, and the maintenance cost is low, thereby greatly prolonging the service life of an elevated road and improving the driving safety.
Description
Technical field
The utility model relates to the bridge construction technical field, specifically a kind of dropproof cantilevered comb shape stretching device.
Background technology
Along with the fast development of urban elevated road, elevated road and speedway are fashionable in the bridge span array, and more and more to the length development, the stroke of corresponding bridge extension joint is also increasing gradually.The stretching device foot of 80 millimeters strokes of general employing of past has compensated the stroke of bridge, all will select the stretching device of 120 millimeters strokes now for use.At present, generally all adopt simply-support comb shape stretching device, it has simple in structure, and the characteristics of easy construction need not go down to change maintenance in totally-enclosed traffic conditions, and maintenance cost is lower.But the stretching device rolled steel dosage of this structure is many, and more complicated is installed, and the sense of the car of jumping is arranged during vehicle ', can produce the phenomenon of nose when especially using on the big bridge of stroke vertical the rotation, has a strong impact on safe driving.Though, also developed a kind of cantilevered comb teeth shape stretching device now, it has not only kept the advantage of simply-support comb teeth shape stretching device, also solved simultaneously the shortcoming of simply-support comb teeth shape stretching device preferably, can reduce half as steel using amount, bridge is vertically installed width and has been reduced, and has reduced vehicle and has jumped car, construction technology is simple, and installation rate is fast.But, this cantilevered comb teeth shape stretching device drops into foreign material such as rubbish in the watertight rubber band from the slit of broach easily, it is very difficult to remove rubbish, rubbish is cumulative, and not only will block spilled water hole influences draining, and influences the dilatation of watertight rubber band, in case the watertight rubber band is damaged, could change after will removing the broach steel plate during transposing, therefore the maintenance cost height is perplexing promoting the use of of cantilevered comb teeth shape stretching device for a long time.
Summary of the invention
The purpose of this utility model is a kind of dropproof cantilevered comb shape stretching device that designs at the deficiencies in the prior art, it adopts dropproof baffle plate and scarfing cinder slope structure, stop that effectively rubbish drops in the watertight rubber band, make its draining unobstructed, again can free dilatation, construction and safeguard all very convenient.
The concrete technical scheme that realizes the utility model purpose is: a kind of dropproof cantilevered comb shape stretching device, comprise two comb teeth shape steel plates, two anchor plates, the comb teeth shape steel plate is fixedly installed on the anchor plate of T-shape with cantilevered, characteristics are that the cantilever of a comb teeth shape steel plate has dropproof baffle plate, the cross section of baffle plate is " L " type, and its both sides are affixed with comb teeth shape steel plate, anchor plate respectively; The cantilever of another comb teeth shape steel plate has dropproof baffle plate, the cross section of this baffle plate is " L " type, and is provided with the reinforcement gusset, and one side of its baffle plate is provided with the slit with the comb teeth shape steel plate, another side and anchor plate are affixed, and the broach of two comb teeth shape steel plates and two baffle plates are that mutual socket joint is slidingly connected.
One side of described two baffle plates is concordant with the increment of comb teeth shape steel plate, another side and anchor plate co-altitude.
The tooth ends of described two comb teeth shape steel plates is provided with the scarfing cinder slope.
The utility model is simple in structure, and easy construction compared with prior art has in the watertight rubber band and can not fall into rubbish, and draining is more unobstructed, and the advantage that maintenance costs is low has improved the application life and the traffic safety of elevated road greatly.

The specific embodiment
Consult accompanying drawing 1～accompanying drawing 2, the utility model comprises two comb teeth shape steel plates 1, two anchor plates 2, the tooth ends of comb teeth shape steel plate 1 is provided with scarfing cinder slope 7, it is fixedly installed on the anchor plate 2 of T-shape with cantilevered, the cantilever turning of one comb teeth shape steel plate 1 has dropproof baffle plate 3, the cross section of baffle plate 3 is " L " type, and its both sides are affixed with comb teeth shape steel plate 1 and anchor plate 2 respectively; The cantilever turning of another comb teeth shape steel plate 1 has dropproof baffle plate 4, the cross section of baffle plate 4 is " L " type, which is provided with and strengthen gusset 6, one side of baffle plate 4 is provided with slit 5 with comb teeth shape steel plate 1, another side and anchor plate 2 are affixed, and the broach of two comb teeth shape steel plates 1 and two baffle plates 3,4 are slidingly connected for mutual socket joint.The thickness in slit 5 is slightly larger than the thickness of baffle plate 3, and baffle plate 3 to insert one side of slit 5, two baffle plates 3,4 concordant with the increment of comb teeth shape steel plate 1, another side is consistent with the height of anchor plate 2.
Consult accompanying drawing 3, the utility model is such installation, use: the utility model is placed on the bridge 9 of both sides, bridge shrinkage joint, adjust the setting height(from bottom) of anchor plate 2, make that two comb teeth shape steel plates 1 and the bridge face 10 of mating formation is concordant, then anchor plate 2 is fixedlyed connected with the built-in fitting 8 on the bridge 9, rubber fastening band 11 is fixedlyed connected with the bridge 9 of both sides, shrinkage joint.Baffle plate 3,4 can stop effectively that dust and rubbish drop in the watertight rubber band 11 from the broach slit of two comb teeth shape steel plates 1, the scarfing cinder slope 7 of the tooth ends of comb teeth shape steel plate 1 can be shoveled out the rubbish in the broach slit automatically in the telescopic process of bridge 9 rising-heat contracting-colds.
