Abstract
The utility model belongs to the technical field of expansion device and discloses a comb type expansion joint. The comb type expansion joint is mainly characterized by comprising a transverse comb tooth plate provided with comb teeth, wherein a vertical bearing plate connected with the transverse comb tooth plate into a whole is arranged below the transverse comb tooth plate; the vertical bearing plate is provided with a waterproof adhesive tape fixing device; the comb teeth are of an arch shape or a taper shape and vertical to or oblique with a long edge of the transverse comb tooth plate; a reinforcing rib is arranged below the comb teeth; the waterproof adhesive tape fixing device is strip steel provided with a C-shaped groove or a metal tube with an edge slot and a built-in plastic inner tube; and the transverse comb tooth plate is provided with at least one row of mounting holes. According to the comb type expansion joint, the transverse comb tooth plate and the vertical bearing plate are integrally casted or welded, so that the overall structure of the comb type expansion joint is simple and firm, the bearing capacity is strong, and the appearance is beautiful; and at the time of solving a jolting problem and reducing noise, the comb type expansion joint also has the advantages of simplicity and convenience in mounting, low cost and long service life.
Description
Technical field
the utility model belongs to the stretching device technical field, relates in particular to a kind of comb type shrinkage joint.
Background technology
Need to install the shrinkage joint in
bridge construction.Current shrinkage joint comprises shaped steel shrinkage joint, three anti-interdigitated electrode structure shrinkage joint, modular shrinkage joint etc.Shaped steel shrinkage joint noise is big, and is not attractive in appearance.Three anti-interdigitated electrode structure shrinkage joint, modular shrinkage joint mounting process complicacy, the constructing operation difficulty is big, and cost is high, damages easily, and application life is shorter.
The utility model content
It is simple that the technical problem that
the utility model will solve just provides a kind of installation, and cost is low, the comb type shrinkage joint of long service life.
are for solving the problems of the technologies described above; The technical scheme that the utility model adopts is: comprise the horizontal comb plate that is provided with broach; Be provided with the vertical force bearing plate that is connected as a single entity with it below the said horizontal comb plate, vertical force bearing plate is provided with the waterproof adhesive tape fastening devices.
its additional technical feature is: described broach is arch or taper; Described broach is perpendicular or tilt with the long limit of horizontal comb plate; Be provided with reinforcing rib below the said broach; Described waterproof adhesive tape fastening devices is to have the bar shaped steel of C type groove or have the limit groove and the metal tube of built-in plastic inner pipe; Described horizontal comb plate is provided with at least one row's installing hole.
comb type shrinkage joint that the utility model provided compared with prior art, laterally comb plate below be provided with the vertical force bearing plate that is connected as a single entity with it, vertical force bearing plate is provided with the waterproof adhesive tape fastening devices.Horizontal comb plate adopts integrally casting or welding with vertical force bearing plate, and overall structure is simple, firm, and bearing capacity is strong, and is specious, when solving top car problem and reducing noise, and simple installation, cost is low, long service life.As required, broach is arch or taper, can be other shapes according to different situations also certainly, and broach is perpendicular or tilt with the long limit of horizontal comb plate.And broach below be provided with reinforcing rib, can reinforce the broach firmness, play a supportive role.According to different demands, the waterproof adhesive tape fastening devices is to have the bar shaped steel of C type groove or have the limit groove and the metal tube of built-in plastic inner pipe.Laterally comb plate is provided with at least one row's installing hole, and whole shrinkage joint is installed firmly.
