Description
Technical field
A kind of bridge expanssion joint waterproof cover of the utility model, belongs to expansion joint field.
Background technique
Bridge expanssion joint: it refers to meet the requirement of bridge floor deformation, usually between two beam-ends, between beam-ends and abutment
Or expansion joint is set in the articulated position of bridge.It is required that expansion joint it is parallel, perpendicular to the both direction of bridge axes, can be from
Solid and reliable by stretching, vehicle driving is out-of-date to answer smoothly, without kick and noise；It wants to prevent rainwater and rubbish soil from penetrating into resistance
Plug；Installation, check, maintenance, eliminate dirt will simple and convenient.At setting expansion joint, railing will be disconnected with deck paving.
Currently, the expansion joint cover on bridge expanssion joint is all the mounting rack and bolt by bottom, two cover plates are pacified
In expansion joint, this structure is adapted to bridge expanssion joint deformation requirements, but when heavy vehicle traveling is square on the cover board,
Bolt strength between cover board and expansion joint is required very high.Many expansion joint cover cover boards are whole, and deformation occurs, often spiral shell
Bolt goes wrong, and causes not to be generally flush with state between cover board and road surface, vehicle tyre may be isolated when serious.
In addition, being separated position between cover board between common bridge expanssion joint, once raining, a large amount of rainwater are along gap
Into in expansion joint, the water proof rubber band below cover board is required very big, it is likely that cause infiltration to happen, and then influence bridge
Beam building life.
Utility model content
To overcome above-mentioned technical problem, the utility model proposes a kind of using overall structure and adapts to bridge expanssion joint and stretches
The waterproof cover of contracting.
To realize the above-mentioned technical purpose, the utility model proposes technical solution are as follows: a kind of bridge expanssion joint waterproof cover,
It include: cover board pedestal, cover board, pressing plate and water-break slot；Two cover board pedestals are symmetrically disposed on the two sides in bridge expanssion joint,
The cover board pedestal is L shape structure, and two sides are provided with the open slot being adapted with cover board pedestal in the bridge expanssion joint,
And cover board pedestal upper end is flushed with road surface, and pressing plate is fixed on the cover board pedestal, the pressing plate is that lower end side is provided with lid
The cube of plate socket, the cover board socket are square groove, are provided with several wedges on the pressing plate above the cover board socket, two
Cover board is provided between a pressing plate, cover board two sides lower end is provided with the cover board being adapted with cover board socket and inserts body, and
Cover board, which is inserted to be provided with above body, matches cover board wedge with wedge, and the cover board pedestal, cover board and pressing plate successively lead to from bottom to top
Cross it is several be bolted, be provided with water-break slot on the cover board pedestal between the cover board and pressing plate.
The cover board socket and cover board insert body and the distance between wedge and cover board wedge are 5~20mm.
The bolt hole of the cover board is round or oval structure, and the diameter of the bolt hole or short axle are greater than etc.
In 5~20mm of the diameter of bolt.
The cover board pedestal upper surface is provided with rubber spacer.
The utility model is compared with prior art with beneficial effect:
One, the utility model cover board uses overall structure, after vehicle driving is above the cover board, cover board at main stress,
And but cover board one end be pressurized when tilting, pressing plate by opposition, if pressing plate again by distribution of forces on bolt stem or its
He fixes on device, can prevent deformation with effective protection covering plate structure.Meanwhile it can prevent rainwater from largely entering inside expansion joint.
Two, between the utility model cover board and pressing plate and cover plate through hole all has certain offset, it is suitable for bridge
The deformation requirement at expansion joint avoids that cover board is jacked up or stretched excessive during bridge deformation.
Three, cooperate between the wedge of the utility model and cover board wedge, it is ensured that existing abundance between cover board and pressing plate
Offset space, while cover board and pressing plate gap are smaller, it is ensured that vehicle driving is steady.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model section view；
Fig. 3 is the utility model pressing plate schematic diagram；
In figure: 1 is cover board pedestal, and 2 be cover board, and 3 be pressing plate, and 4 be water-break slot, and 5 be cover board socket, and 6 be wedge, and 7 be lid
Plate inserts body, and 8 be cover board wedge.
Specific embodiment
It is as shown in Figure 1 to Figure 3: a kind of bridge expanssion joint waterproof cover, comprising: cover board pedestal 1, cover board 2, pressing plate 3 and to move back
Sink 4；Two cover board pedestals 1 are symmetrically disposed on the two sides in bridge expanssion joint, and the cover board pedestal 1 is L shape structure,
Two sides are provided with the open slot being adapted with cover board pedestal 1 in the bridge expanssion joint, and 1 upper end of cover board pedestal and road surface are neat
It is flat, pressing plate 3 is fixed on the cover board pedestal 1, the pressing plate 3 is the cube that lower end side is provided with cover board socket 5, the lid
Plate socket 5 is square groove, is provided with several wedges 6 on the pressing plate 3 of 5 top of the cover board socket, between two pressing plates 3
It is provided with cover board 2, the 2 two sides lower end of cover board is provided with the cover board being adapted with cover board socket 5 and inserts body 7, and cover board is inserted on body 7
Side, which is provided with, matches cover board wedge 8 with wedge 6, and the cover board pedestal 1, cover board 2 and pressing plate 3 pass sequentially through several from bottom to top
It is bolted, is provided with water-break slot 4 on the cover board pedestal 1 between the cover board 2 and pressing plate 3.
The cover board socket 5 inserts body 7 with cover board and the distance between wedge 6 and cover board wedge 8 are 5~20mm.
