Abstract
The utility model discloses an anti-fall toothed crossover joint simply-supported comb-tooth-shaped expansion device, which comprises a movable toothed plate, a fixed toothed plate and a rubber waterstop band. The expansion device is characterized in that the movable toothed plate is in the shape of comb teeth, and the bottom surface of the comb-tooth section of the movable toothed plate is fixedly connected with an anti-fall plate provided with a baffle; the fixed toothed plate is also in the shape of comb teeth, the bottom surface of the comb-tooth section of the fixed toothed plate is provided with a gap, a stainless steel slide plate is arranged below the gap; the comb teeth of the fixed toothed plate and comb teeth of the movable toothed plate are crossed to each other and horizontally arranged on the anti-fall plate, and the anti-fall plate are slidably connected with the stainless steel slide plate. The expansion device is simple in structure and convenient in installation and maintenance, can prevent wastes and impurities falling into the rubber waterstop band more effectively compared with the prior art, and can automatically discharge the waste and impurities among the comb teeth out of a groove, the rubber waterstop band can expand and retract optionally, and drainage is more smooth, thereby increasing installation speed of the expansion device and prolonging service life thereof.
Description
Technical field
The utility model relates to the bridge construction technical field, and specifically a kind of dropproof tooth is striden seam simply-support comb teeth shape stretching device.
Background technology
The comb teeth shape stretching device is divided into two kinds by the mechanics form: a kind of is simply-support comb teeth shape stretching device, another kind is a cantilevered comb teeth shape stretching device. simply-support comb teeth shape stretching device can be divided into two kinds again, a kind of is traditional simply-support comb teeth shape stretching device (the real wide plate that is movable comb plate is striden seam), and another kind is that tooth is striden seam comb teeth shape stretching device.
Require the low clearance stretching device on the bridge now, generally all adopt traditional simply-support comb shape stretching device, it has driving steadily, and noise is low, construction and advantage easy to maintenance, and it need be in the repair and replacement of going down of totally-enclosed traffic conditions, and maintenance cost is also lower.Because urban elevated road and speedway are fashionable in the bridge span array, more and more develop to length, the stroke of corresponding bridge extension joint also increases, and the past, the general stretching device of 80 millimeters strokes that adopts can solve, all will select the stretching device of 120 millimeters strokes now for use.Consider that from factors such as design, construction, maintenances bridge telescopic variation amount generally all adopts traditional simply-support comb teeth shape stretching device in the time of 100 millimeters-420 millimeters at present.Tradition simply-support comb teeth shape stretching device has the advantage of grade easy to maintenance, and steel using amount is many, the sense of jumping car is obvious, it is complicated to install, installation rate is slow but exist, and nut gets loose easily, especially 120 millimeters shortcomings such as comb teeth shape stretching device unit price height.Tooth is striden seam simply-support comb teeth shape stretching device, the advantage that is not only keeping traditional simply-support comb teeth shape stretching device, also solved simultaneously the shortcoming of its existence, can reduce 30%-50% as steel using amount, bridge is vertically installed width and has been reduced, and can reduce vehicle and jump car, and construction technology is simple, installation rate is accelerated, and the duration shortens.But, tooth is striden seam simply-support comb teeth shape stretching device and is used less, having weak point is exactly that rubbish, foreign material will drop into from the backlash in the watertight rubber band, and it is very difficult to remove foreign material, and foreign material rubbish is cumulative, not only to block spilled water hole and influence draining, also to influence watertight rubber band dilatation,, could change after will removing the broach steel plate during transposing in case the watertight rubber band is damaged, the repair cost height, also long-term thus puzzlement is promoted tooth and is striden seam simply-support comb teeth shape stretching device.
The utility model content
The purpose of this utility model is that a kind of dropproof tooth that designs at the deficiencies in the prior art is striden seam simply-support comb teeth shape stretching device, it adopts dropproof plate to stop that effectively rubbish, foreign material fall in the rubber fastening band, make the free dilatation of rubber fastening band freely, draining is more smooth and easy, improves the installation rate and the application life of stretching device greatly.
Realize that concrete technical scheme of the present utility model is: a kind of dropproof tooth is striden seam simply-support profile of tooth stretching device, comprise swing tooth plate, fixed tooth plate and rubber fastening band, be characterized in that swing tooth plate is a comb teeth shape, the bottom surface of its comb-tooth segments is affixed with the dropproof plate that is provided with baffle plate, and baffle plate and dropproof plate are "T"-shaped affixed; Fixed tooth plate is a comb teeth shape, and the bottom surface of its comb-tooth segments has the space, and the stainless steel slide plate is set under the space, and the stainless steel slide plate is under the comb-tooth segments bottom surface that " door " font is installed in fixed tooth plate by another baffle plate and side plate; Swing tooth plate, fixed tooth plate are fixedly installed on the Liang Tishang of both sides, shrinkage joint by several anchor plates; Rubber fastening band is arranged on the shrinkage joint, and its two ends are affixed with two baffle plates respectively; The broach of fixed tooth plate intersects horizontal on dropproof plate mutually with the broach of swing tooth plate, and dropproof plate is connected with the stainless steel slide plate slides.
The height in described space is slightly larger than the thickness of dropproof plate.
The broach of described swing tooth plate, fixed tooth plate is provided with the scarfing cinder slope.
The utility model is simple in structure, installation, easy to maintenance, can stop effectively that compared with prior art rubbish, foreign material fall in the watertight rubber band, and the rubbish foreign material between broach oneself can be shoveled out in the groove, make the free dilatation of watertight rubber band freely, draining is more smooth and easy, improves the application life of stretching device greatly.
