Abstract
The invention belongs to the technical field of an expansion device, and discloses a dustproof comb-type expansion joint. The main technical characteristic is that the expansion joint comprises transverse comb plates with multiple comb teeth, a groove is formed between the adjacent comb teeth, dustproof plates are arranged below the transverse comb plates, and the dustproof plates are arranged at the grooves among the comb teeth; and the dustproof plate is composed of a rubber elastic tail plate and a metal top plate in integral connection. In the dustproof comb-type expansion joint provided by the utility model, when the adjacent transverse comb plates stagger mutually to satisfy the need for expansion of the beam, the dust falls onto the dustproof plates instead of the sealing adhesive strip from the grooves among the comb teeth of the transverse comb plates, so as to prevent the influence on the sealing adhesive strip and prolong the service life of the sealing adhesive strip.
Description
Technical field
the utility model belongs to the stretching device technical field, relates in particular to a kind of dustproof comb type shrinkage joint.
Background technology
Need to install the shrinkage joint in
bridge construction.Current shrinkage joint comprises the side bar of paired setting; Be provided with sealing joint strip between side bar; For reduce vehicle through the time jolt, for having the horizontal comb type tooth plate of broach, be groove between adjacent fingers above the side bar; The broach and the groove of relative horizontal comb type tooth plate are complementary, and satisfy the flexible of beam body through the mutual changing of the relative positions of adjacent transverse comb type tooth plate.This shrinkage joint laterally groove between the broach of comb type tooth plate falls rubbish easily, and sealing joint strip is impacted, and influences its application life.
The utility model content
The technical problem that
the utility model will solve just provides the dustproof comb type shrinkage joint that is not easy to fall rubbish between a kind of broach of horizontal comb type tooth plate.
for solving the problems of the technologies described above, the technical scheme that the utility model adopts is: comprising the horizontal comb plate that is provided with a plurality of broach, is groove between adjacent fingers, is provided with dust excluding plate below the said horizontal comb plate.
its additional technical feature is: described dust excluding plate is arranged on the groove between broach; Said dust excluding plate is made up of the caoutchouc elasticity tailgate and the metal top plate that connect as one.
dustproof comb type shrinkage joint that the utility model provided compared with prior art, laterally comb plate below be provided with dust excluding plate.When beam body flexible satisfied in the mutual changing of the relative positions of adjacent transverse comb type tooth plate; Can fall on the dust excluding plate if there is rubbish to fall by the groove between the broach of horizontal comb type tooth plate; Can not fall the sealing joint strip place, thereby can not impact, prolong its application life sealing joint strip.And dust excluding plate only is arranged on the groove between broach, and dust excluding plate is made up of the caoutchouc elasticity tailgate and the metal top plate that connect as one.When adjacent transverse comb type tooth plate away from the time, metal top plate is horizontal under the effect of caoutchouc elasticity tailgate.When adjacent transverse comb type tooth plate near the time, broach presses down metal top plate, metal top plate is that fulcrum moves down with the caoutchouc elasticity tailgate.When adjacent transverse comb type tooth plate once more away from the time, broach reduces metal top plate pressure, metal top plate is the fulcrum recovery horizontal that moves up with the caoutchouc elasticity tailgate, and the superincumbent rubbish that can land ejects.
Description of drawings
Fig. 1 is the structural representation at the dustproof comb type shrinkage joint of the utility model.
The specific embodiment
further specify below in conjunction with the structure of accompanying drawing to the dustproof comb type shrinkage joint that the utility model provided.
are as shown in Figure 1; The dustproof comb type shrinkage joint of the utility model comprises horizontal comb plate 1 and sealing joint strip 2; Laterally comb plate 1 is provided with a plurality of broach 3; 3 of adjacent fingers are groove 4, and groove 4 places are provided with the dust excluding plate that is made up of caoutchouc elasticity tailgate that connects as one 5 and metal top plate 6.
dustproof comb type shrinkage joint that the utility model provided; When beam body flexible satisfied in the 1 mutual changing of the relative positions of adjacent transverse comb type tooth plate; If having rubbish to be fallen by groove 4 places of 3 of the broach of horizontal comb type tooth plate 1 can fall on the dust excluding plate that is made up of caoutchouc elasticity tailgate that connects as one 5 and metal top plate 6; Can not fall sealing joint strip 2 places, thereby can not impact, prolong its application life sealing joint strip 2.And only be arranged on groove 4 places of 3 of broach by the dust excluding plate that caoutchouc elasticity tailgate 5 that connects as one and metal top plate 6 constitute, when adjacent transverse comb type tooth plate 1 away from the time, metal top plate 6 is horizontal under 5 effects of caoutchouc elasticity tailgate.When adjacent transverse comb type tooth plate 1 near the time, broach 3 presses down metal top plate 6, metal top plate 6 is that fulcrum moves down with caoutchouc elasticity tailgate 5.When adjacent transverse comb type tooth plate 1 once more away from the time, 3 pairs of metal top plate 6 pressure of broach reduce, metal top plate 6 is the fulcrum recovery horizontal that moves up with caoutchouc elasticity tailgate 5, and the superincumbent rubbish that can land ejects.
dustproof comb type shrinkage joint that the utility model provided is not limited only to said structure, but no matter be which kind of form, so long as laterally comb plate below be provided with dust excluding plate, all fall into the utility model protection domain.
Claims (3)
1. dustproof comb type shrinkage joint comprises the horizontal comb plate that is provided with a plurality of broach, is groove between adjacent fingers, it is characterized in that: be provided with dust excluding plate below the said horizontal comb plate.
2. dustproof comb type according to claim 1 shrinkage joint, it is characterized in that: described dust excluding plate is arranged on the groove between broach.
3. dustproof comb type according to claim 1 and 2 shrinkage joint, it is characterized in that: said dust excluding plate is made up of the caoutchouc elasticity tailgate and the metal top plate that connect as one.
