Abstract
The utility model belongs to the technical field of expansion devices and discloses a double waterproof and dustproof bridge expansion joint. The technical scheme mainly includes that the bridge expansion joint comprises pairwise arranged steel boundary beams, an upper water stop is arranged between the steel boundary beams, and fixing plates are arranged on the lower portions of the steel boundary beams and connected to the ends of a lower water stop. According to the bridge expansion joint, the upper water stop and the lower water stop form a double waterproof and dustproof structure, when the upper water stop falls off or is damaged, the lower water stop can still perform the waterproof and dustproof functions, so that the bridge expansion joint is good in using effect, long in service life, simple in structure and convenient to replace.
Description
Technical field
The utility model belongs to the stretching device technical field, relates in particular to a kind of dual water proof and dust proof bridge expanssion joint.
Background technology
Bridge extension joint comprises single seam and many seams.Single seam bridge extension joint comprises the shaped steel side bar of paired setting, is provided with rubber fastening band between the shaped steel side bar.Many seam bridge extension joints comprise the shaped steel side bar of paired setting, are provided with at least one shaped steel central sill between the shaped steel side bar that is provided with in pairs, between shaped steel side bar and shaped steel central sill, be respectively arranged with rubber fastening band between shaped steel central sill and shaped steel central sill.The rubber fastening band of this bridge extension joint, in use if accumulate foreign material such as stone is arranged, when vehicle passed through, rubber fastening band came off easily or is damaged, influences result of use, reduction of service life.
The utility model content
It is good that the technical problem that the utility model will solve just provides a kind of result of use, the dual water proof and dust proof bridge expanssion joint of long service life.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: the shaped steel side bar that comprises paired setting; Be provided with the top waterstop between the shaped steel side bar, the bottom of said shaped steel side bar is provided with fixed head, and the end of bottom waterstop is connected with fixed head.
Its additional technical feature is: described fixed head is the L type, and the end of bottom waterstop is provided with U type draw-in groove; Be provided with at least one shaped steel central sill between the shaped steel side bar of said paired setting, the middle part of shaped steel central sill or bottom are provided with the fixed head that connects the bottom waterstop.
The dual water proof and dust proof bridge expanssion joint that the utility model provided, compared with prior art, the bottom of shaped steel side bar is provided with fixed head, and the end of bottom waterstop is connected with fixed head.Such bridge expanssion joint, top waterstop and bottom waterstop constitute two-layer waterproof and dustproof structure, when the top waterstop occurs coming off or breakage; The bottom waterstop still plays the water proof and dust proof effect, makes the bridge expanssion joint result of use good, long service life; It is simple in structure, and it is convenient to change.And fixed head is the L type, and the end of bottom waterstop is provided with U type draw-in groove, in use, U type draw-in groove is stuck on the vertical plane of L type fixed head and gets final product, and installing and replacing is more convenient.Be provided with at least one shaped steel central sill between the shaped steel side bar that is provided with in pairs, the middle part of shaped steel central sill or bottom are provided with the fixed head that connects the bottom waterstop, and then the shrinkage joint becomes many seams by single seam, applicable to multiple occasion.
Description of drawings
Fig. 1 is first kind of structural representation of the dual water proof and dust proof bridge expanssion joint of the utility model;
Fig. 2 is second kind of structural representation of dual water proof and dust proof bridge expanssion joint;
Fig. 3 is the third structural representation of dual water proof and dust proof bridge expanssion joint.
The specific embodiment
Further specify below in conjunction with the structure of accompanying drawing the dual water proof and dust proof bridge expanssion joint that the utility model provided.
As shown in Figure 1; The dual water proof and dust proof bridge expanssion joint of the utility model comprises the shaped steel side bar 1,2 of paired setting; 1,2 of shaped steel side bars are provided with top waterstop 3, and the bottom of shaped steel side bar 1,2 is provided with fixed head 4, and the end of bottom waterstop 5 is connected with fixed head 4; Fixed head 4 is the L type, and the end of bottom waterstop 5 is provided with U type draw-in groove 6.As shown in Figure 2; 1,2 of shaped steel side bars that are provided with in pairs are provided with a shaped steel central sill 7; 7 of shaped steel side bar 1,2 and shaped steel central sills are respectively arranged with top waterstop 3; The bottom of shaped steel side bar 1,2 is provided with the fixed head 4 that is connected bottom waterstop 5 with the middle part of shaped steel central sill 7, and fixed head 4 is the L type, and the end of bottom waterstop 5 is provided with U type draw-in groove 6.As shown in Figure 3; 1,2 of shaped steel side bars that are provided with in pairs are provided with a plurality of shaped steel central sills 7; 7 of shaped steel side bar 1,2 and shaped steel central sills and 7 adjacent of shaped steel central sills are respectively arranged with top waterstop 3; The bottom of shaped steel side bar 1,2 is provided with the fixed head 4 that is connected bottom waterstop 5 with the middle part of shaped steel central sill 7, and fixed head 4 is the L type, and the end of bottom waterstop 5 is provided with U type draw-in groove 6.
The dual water proof and dust proof bridge expanssion joint that the utility model provided, the bottom of shaped steel side bar 1,2 is provided with fixed head 4, and the end of bottom waterstop 5 is connected with fixed head 4.Such bridge expanssion joint, top waterstop 3 constitutes two-layer waterproof and dustproof structure with bottom waterstop 5, when top waterstop 3 occurs coming off or breakage; Bottom waterstop 5 still plays the water proof and dust proof effect, makes the bridge expanssion joint result of use good, long service life; It is simple in structure, and it is convenient to change.And fixed head 4 is the L type, and the end of bottom waterstop 5 is provided with U type draw-in groove 6, in use, U type draw-in groove 6 is stuck on the vertical plane of L type fixed head 4 and gets final product, and installing and replacing is more convenient.1,2 of shaped steel side bars that are provided with in pairs are provided with at least one shaped steel central sill 7, and the middle part of shaped steel central sill 7 or bottom are provided with the fixed head 4 that connects bottom waterstop 5, and then the shrinkage joint becomes many seams by single seam, applicable to multiple occasion.
The dual water proof and dust proof bridge expanssion joint that the utility model provided is not limited only to said structure; But no matter be which kind of form; So long as be provided with fixed head, the expanded joint structure that the end of bottom waterstop is connected with fixed head all falls into the utility model protection domain.
