Its additional technical feature is: the width of described corrosion resistant plate is equal to or greater than 1/2nd of double wedge length;
Described rubber seal tape is fixed on riser lower end, bottom, and rubber seal tape fixes by bolt and bottom riser;
The bearing of described rubber seal tape is provided with elastic layering;
Described rubber seal tape is provided with a plurality of longitudinal holes;
Double wedge, the groove of transverse slat inside edge, described top is trapezoidal, arc, taper, rectangle.
A kind of large displacement antidetonation buffering stretching compression apparatus provided by the utility model compared with prior art, shaped steel side bar consists of top transverse slat and bottom riser, top transverse slat and bottom riser are integrated the orthogonal plane of manufacture, and the edge of top transverse slat inner side is the concavo-convex of double wedge, groove circulation setting.This shaped steel side bar is integrally manufactured, simple in structure, and the edge of top transverse slat inner side is the concavo-convex of double wedge, groove circulation setting, and single seam stretching device can reach the stroke of 0～240mm.Stroke has increased greatly, meet the needs of general bridge shallow buried extensible device, reduced and jumped the impact that car brings to bridge, extended the application life of stretching device and bridge, reduce the pollution of NOISE ON ENVIRONMENT, be specially adapted to the regional bridge that difference variation is larger.Below the transverse slat of top, be provided with corrosion resistant plate; on top, transverse slat is stamped through hole; corrosion resistant plate is connected with top transverse slat by dormant bolt; stretching device is in telescopic process; rubbish incidental will drop on above corrosion resistant plate, can not fall into seam, has so just guaranteed telescopic displacement; protected rubber seal tape can not punctured by sharp shaped material simultaneously, ground away.As required, the width of corrosion resistant plate is equal to or greater than 1/2nd of double wedge length.
And rubber seal tape is fixed on riser lower end, bottom, rubber seal tape fixes by bolt and bottom riser, and the bearing of rubber seal tape is provided with elastic layering.During installation, by the uniform screwed hole of stamping on the riser of bottom, spread compression elastic layering, the bolt of screwing on compresses, and has optimized rubber seal tape installation, has strengthened the waterproof effect of rubber seal tape, and rubber seal tape is installed more convenient, more firm.Rubber seal tape is provided with a plurality of longitudinal holes, and rubber seal tape adopts porous flexible, shaped steel side bar lower room is taken as far as possible, reduces bulky rubbish and falls into seam, and water resistance is further strengthened, and rubber seal tape is more firm, and the life-span is longer.As required, the double wedge of top transverse slat inside edge, groove are trapezoidal, arc, taper, rectangle.
With respect to common modular expansion device and comb teeth retractor device, large displacement antidetonation buffering stretching compression apparatus low price provided by the utility model, applicable aspect is wide, has reduced jumping car and noise, institute's preformed groove groove width of staying is few, groove depth is shallow, and production and processing is convenient and swift, and safety firmly, life-span is long, convenient transportation, installs simply, changes easily.Be applicable to different types of rridges, the bridge that especially temperature difference is large, groove depth is shallow, displacement is large.
