Abstract
The invention relates to a dilatation joint of a bridge, comprising a fixed seat (1) and a sliding seat (2) which are positioned at both sides of a commissure of the dilatation joint. The dilatation joint of the bridge is characterized in that the fixed seat (1) is fixed at one side of the commissure of the dilatation joint; the sliding seat (2) contacts the surface of the other side of the commissure (6) of the dilatation joint slidably; a connection plate (4) shielding the dilatation joint is arranged between the fixed seat (1) and the sliding seat (2); and both sides of the connection plate (4) are respectively articulated with the fixed seat (1) and the sliding seat (2). The dilatation joint is in an all-metal structure, has ageing resistance, can provide larger horizontal displacement amount, adopt the unique connection plate structure and realize vertical displacement and rotation displacement.
Description
Technical field
The present invention relates to the bridge engineering parts, relate in particular to a kind of bridge expanssion joint.
Background technology
The material of the telescoping member that existing railroad bridge shrinkage joint is main is a rubber, and its shortcoming is perishable, and is not ageing-resistant, needs periodic replacement.Shrinkage joint displacement on railroad bridge is subjected to the restriction of its structure, all can only satisfy the displacement of horizontal direction, in case bridge has the discrepancy in elevation, when perhaps needing certain rotation displacement, just can not meet the demands, and is lost efficacy in the shrinkage joint.
Chinese patent CN1560371 discloses a kind of bridge expansion gap device, and the displacement of this device horizontal direction is little, and can not realize vertical displacement and rotation displacement, is difficult to satisfy the requirement of railroad bridge.
Summary of the invention
The objective of the invention is to propose a kind of bridge expanssion joint simple in structure, long-lived, make it that displacement of big horizontal direction can not only be provided, can also realize vertical displacement and rotation displacement in order to solve the deficiency that the above-mentioned background technology exists.
Following technical scheme is adopted in invention for achieving the above object: bridge expanssion joint, comprise the holder 1 and the sliding seat 2 that are positioned at sealing both sides, shrinkage joint, it is characterized in that described holder 1 is fixed in shrinkage joint sealing 6 one sides, described sliding seat 2 and the surface sliding-contact of shrinkage joint sealing 6 opposite sides, be provided with the junction plate 4 that flexible sealing is covered between holder 1 and sliding seat 2, junction plate 4 both sides are hinged with holder 1 and sliding seat 2 respectively.
In such scheme, also can be hinged between described junction plate and the holder, between junction plate and the sliding seat with bearing pin, above-mentioned bearing pin is axially and the parallel longitudinal of shrinkage joint sealing.
In such scheme, also can be hinged between described junction plate 4 and the holder 1, between junction plate 4 and the sliding seat 2 with bulb.
In such scheme, described holder, sliding seat and gripper shoe can be arranged in parallel along the shrinkage joint direction.
In such scheme, the position of described sliding seat and the surface sliding-contact of shrinkage joint sealing opposite side is provided with sliding pair, and sliding pair is to be made of mirror face stainless steel and wearing plate.
Can be provided with at sealing place, above-mentioned shrinkage joint and to be used for telescopic band that the shrinkage joint sealing is covered.
In such scheme, lean on sliding seat 2 one sides also to be provided with at the shrinkage joint sealing and can prevent that railway quarrel stone from entering the slag stopper 5 of sliding seat 2 slide planes, slag stopper 5 one ends are fixed on the sliding seat 2, the other end and gripper shoe 3 surfaces are slidingly connected, gripper shoe 3 surfaces are parallel with the slide plane of sliding seat 2, and described gripper shoe 3 is fixed in the bridge surface of sliding seat opposite side.
Shrinkage joint of the present invention is for being applicable to a kind of shrinkage joint of railroad bridge, and except that satisfying the common shrinkage joint of bridge desired properties, this shrinkage joint can also provide vertical displacement and rotation displacement.This expanded joint structure is an all metal construction, and is not only simple in structure, and aspect stressed and ageing-resistant aspect have certain advantage.Structures such as the sliding seat that adopt at this shrinkage joint, junction plate, slag stopper can provide better telescopicing performance for bridge.Sliding seat employing of the present invention is contacted with substructure by the mode that mirror face stainless steel and wearing plate constitute sliding pair, has improved and has slided and wear-resisting performance, for the shrinkage joint provides the displacement of horizontal direction, and has increased displacement.Junction plate particularly of the present invention adopts articulated structure to be connected with sliding seat with holder respectively, make this shrinkage joint that the displacement of horizontal direction not only can be provided, and can realize vertical displacement, and can provide certain rotation displacement, thereby can tackle the relatively complicated displacement mode of bridge.
Feature of the present invention and other correlated characteristics are described in further details by embodiment below in conjunction with accompanying drawing, so that colleague technician's understanding.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Referring to Fig. 1, present embodiment is used for railroad bridge beam body and draws shrinkage joint sealing 6 between the bridge, comprises holder 1, sliding seat 2, gripper shoe 3, slag stopper 5 and junction plate 4.Described holder 1 and sliding seat 2 lay respectively at shrinkage joint sealing 6 both sides, and holder 1 usefulness anchor rod 7 is fixed in shrinkage joint sealing 6 and draws bridge 8 one sides.Sliding seat 2 and the 9 surperficial sliding-contacts of shrinkage joint sealing 6 opposite side bridge beam body, the position of sliding-contact is provided with sliding pair, and sliding pair is to be made of mirror face stainless steel and wearing plate.Gripper shoe 3 usefulness anchor rods 7 are fixed in bridge beam body 9 surfaces of sliding seat 2 away from shrinkage joint sealing 6 one sides.Described junction plate 4 cross-over connections are in holder 1 with above the sliding seat 2, and are hinged with bearing pin between junction plate 4 and the holder 1, also use bearing pin hinged between junction plate 4 and the sliding seat 2, the parallel longitudinal of the axial and shrinkage joint sealing 6 of bearing pin.Described slag stopper 5 cross-over connections are in the surface of sliding seat 2 and gripper shoe 3, fixedly connected between slag stopper 5 one ends and the sliding seat, and as welding, bolt connection etc., the other end is shelved on the gripper shoe surface, is slidingly connected with the gripper shoe surface.Slag stopper 5 is used to stop that bridge floor road quarrel enters the sliding pair below the sliding seat 2.
Said fixing seat, sliding seat and gripper shoe are arranged in parallel along the shrinkage joint direction.Be provided with at shrinkage joint sealing 6 places and be used for telescopic band 10 that shrinkage joint sealing 6 is covered.
All metal construction is adopted at this shrinkage joint, and is ageing-resistant; Bigger horizontal displacement can be provided; Adopt unique junction plate structure, can realize vertical displacement and rotation displacement.
