Abstract
The utility model belongs to the technical field of retractable devices, and discloses a comb-type expansion joint with easily replaceable rubber strips. The main technical characteristics are that the expansion joint includes paired boundary beams, wherein rubber strips are arranged among the boundary beams; the end part of each rubber strip is a column-shaped body with a through hole formed at the center; and an inserting rod is arranged in each through hole. During the installation of the comb-type expansion joint with the easily replaceable rubber strips, provided by the utility model, the column-shaped end parts of the rubber strips are first installed on the boundary beams, then the inserting rods are inserted in the through holes at the centers of the column-shaped bodies, so that the column-shaped end parts are tightly contacted with the boundary beams; and after the rubber strips are aged or damaged, the inserting rods are firstly drawn out of the through holes at the centers of the column-shaped bodies, so that the column-shaped end parts of the rubber strips can be taken out of the boundary beams conveniently, the new rubber strips can be installed again, and the rubber strips can be replaced very conveniently.
Description
Technical field
the utility model belongs to the stretching device technical field, relates in particular to a kind of easy replacing adhesive tape comb type shrinkage joint.
Background technology
Need to install the shrinkage joint in
bridge construction.The shrinkage joint comprises the shaped steel of paired setting, is provided with sealing joint strip between shaped steel because the end of sealing joint strip contact with shaped steel closely, when adhesive tape wear out or damage after change and be not easy.
The utility model content
The technical problem that
the utility model will solve just provides the easy replacing adhesive tape comb type shrinkage joint that a kind of adhesive tape is aging or the damage back is changed easily.
for solving the problems of the technologies described above, the technical scheme that the utility model adopts is: comprise the side bar of paired setting, be provided with adhesive tape between side bar, the end of said adhesive tape is the cylindrical body that the center has through hole, is provided with plunger in the through hole.
its additional technical feature is: the outer wall of said cylindrical body is provided with at least one raised line; Described raised line is three roads; Described side bar comprises the horizontal comb plate that is provided with broach, 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; 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.
easy replacing adhesive tape comb type shrinkage joint that the utility model provided compared with prior art, the end of adhesive tape is the cylindrical body that the center has through hole, is provided with plunger in the through hole.Elder generation is installed in the cylindrical body end of adhesive tape on the side bar during installation, then plunger is inserted the through hole at cylindrical body center, and the cylindrical body end is closely contacted with side bar.After adhesive tape wears out or damages, earlier plunger is extracted out by the through hole at cylindrical body center, can very easily the cylindrical body end of adhesive tape be taken off by side bar, newer adhesive tape to be reinstalled, adhesive tape is changed rich normal convenience.And the outer wall of cylindrical body is provided with at least one raised line, can the reinforcing prop body and the frictional force of side bar, connect more firm.As required, raised line is three roads or other any roads.And side bar comprises the horizontal comb plate that is provided with broach, 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; Then laterally comb plate can adopt integrally casting or welding with vertical force bearing plate, and the side bar overall structure is simple, firm, and bearing capacity is strong; Specious; Simple installation, cost is low, long service life.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.
Description of drawings
Fig. 1 is prone to change first kind of structural representation at adhesive tape comb type shrinkage joint for the utility model;
Fig. 2 is for being prone to change second kind of structural representation at adhesive tape comb type shrinkage joint.
The specific embodiment
further specify below in conjunction with the structure of accompanying drawing to the easy replacing adhesive tape comb type shrinkage joint that the utility model provided.
are as shown in Figure 1; The utility model is prone to change adhesive tape comb type shrinkage joint and comprises the horizontal comb plate 1 of paired setting and the side bar of vertical force bearing plate 2 formations; Be provided with adhesive tape 3 between side bar, the end of adhesive tape 3 is the cylindrical body 5 that the center has through hole 4, is provided with plunger 6 in the through hole 4; The outer wall of cylindrical body 5 is provided with raised line 7, and vertical force bearing plate 2 is provided with the waterproof adhesive tape fastening devices of bar shaped steel 9 formations that have C type groove 8.As shown in Figure 2, vertical force bearing plate 2 is provided with the metal tube 12 that has limit groove 10 and built-in plastic inner pipe 11.
easy replacing adhesive tape comb type shrinkage joint that the utility model provided, elder generation is installed in cylindrical body 5 ends of adhesive tape 3 on the side bar during installation, then plunger 6 is inserted the through hole 4 at cylindrical body 5 centers, and cylindrical body 5 ends are closely contacted with side bar.After adhesive tape 3 wears out or damages, earlier plunger 6 is extracted out by the through hole 4 at cylindrical body 5 centers, can very easily cylindrical body 5 ends of adhesive tape 3 be taken off by side bar, newer adhesive tape 3 to be reinstalled, adhesive tape 3 is changed rich normal convenience.And the outer wall of cylindrical body 5 is provided with at least one raised line 7, can the reinforcing prop body 5 with the frictional force of side bar, connect more firm.As required, raised line 7 is three roads or other any roads.And side bar comprises the horizontal comb plate 1 that is provided with broach, laterally comb plate 1 below be provided with the vertical force bearing plate 2 that is connected as a single entity with it, vertical force bearing plate 2 is provided with the waterproof adhesive tape fastening devices; Then laterally comb plate 1 can adopt integrally casting or welding with vertical force bearing plate 2, and the side bar overall structure is simple, firm, and bearing capacity is strong; Specious; Simple installation, cost is low, long service life.According to different demands, the waterproof adhesive tape fastening devices is the metal tube 12 that has the bar shaped steel 9 of C type groove 8 or have limit groove 10 and built-in plastic inner pipe 11.
easy replacing adhesive tape 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 the end of adhesive tape is the cylindrical body that the center has through hole, be provided with plunger in the through hole, all fall into the utility model protection domain.
