Abstract
The utility model discloses safeguard structure at a kind of bridge expanssion joint, telescopic device is preset with two sections of seaming position preformed grooves of bridge, and telescopic device is located at gaping of joints position and is provided with two fishbacks, middle and lower part insertion is provided with rubber fastening band between two fishbacks, i.e. rubber fastening band one end is embedded into the groove of sides adjacent fishback in itself, and the other end is embedded into the groove of another fishback in itself；Wherein, rubber fastening band blocks the gaping of joints of telescopic device completely；Polyurethane is filled with the recess region that two fishbacks are surrounded with rubber fastening band, and optionally will be higher than areas at both sides positioned at bridge central region in filled polyurethane, can so form an inclined-plane diversion trench；Overall structure is simple, forms a groove for being used for filling polyurethane by the assembling structure of fishback and rubber fastening band, forms stabilized seal after filling polyurethane, the deposition step of whole device is simple, and drainage effect is good.
Description
Technical field
Bridge field is the utility model is related to, safeguard structure at more particularly to a kind of bridge expanssion joint.
Background technology
Per adjacent two sections, linking is both provided with a seam construction to bridge, and traditional seam construction is the spacious of open-top
Open type expansion joint, this structure is since sealing problem causes internal damage rate height, maintenance frequent, and drainage effect is bad.
The content of the invention
The utility model is directed to above-mentioned technical problem, proposes safeguard structure at a kind of bridge expanssion joint of new structure.
To achieve the above objectives, it is achieved through the following technical solutions：
Safeguard structure at a kind of bridge expanssion joint, telescopic device is preset with two sections of seaming position preformed grooves of bridge,
And telescopic device is located at gaping of joints position and is provided with two fishbacks, between two fishbacks middle and lower part insertion be provided with rubber water-proof
Band, i.e. rubber fastening band one end are embedded into the groove of sides adjacent fishback in itself, and the other end is embedded into another fishback sheet
In the groove of body；
Wherein, rubber fastening band blocks the gaping of joints of telescopic device completely；What two fishbacks were surrounded with rubber fastening band
Polyurethane is filled with recess region, and optionally will be higher than two border areas positioned at bridge central region in filled polyurethane
Domain, can so form an inclined-plane diversion trench；
Further, rubber fastening band is W type rubber fastening bands；
It is provided with the top of telescopic device for preventing the polyurethane of filling from protruding from the pressing plate of bridge upper end face, and pressing plate
It is individually fixed in for two on the left of telescopic device top clearance and on the right side of top clearance, this mechanism mainly prevents filler with pressing plate
Polyurethane dilatancy largely protrudes from bridge surface；
Further, two fishbacks are Multilayer-tooth fishback, each layer relative to tooth form into groove in it is one embedded
Rubber fastening band, on above-below direction per two neighboring rubber fastening band between be filled with polyurethane in gap, secondary structure is mainly protected
The waterproof effect of multilayer is demonstrate,proved, while ensure that influence of the construction stretch deformation to waterproof effect.
Using the utility model of above-mentioned technical proposal, overall structure is simple, passes through fishback and the dress of rubber fastening band
Distribution structure forms a groove for being used for filling polyurethane, and stabilized seal, the arrangement step of whole device are formed after filling polyurethane
Rapid simple, drainage effect is good, and due to being that filling sealing has extraordinary protective effect for lower part, greatly reduces
Later period maintenance frequency.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand the skill of the utility model
Art means, and being practiced according to the content of specification, and in order to allow the above and other purpose, feature of the utility model
It can be become apparent with advantage, below especially exemplified by preferred embodiment, and coordinate attached drawing, described in detail as follows.
Brief description of the drawings
The utility model totally 1 width attached drawing, wherein：
Fig. 1 is the cross-sectional view of the utility model.
In figure：1st, preformed groove, 2, telescopic device, 3, fishback, 4, rubber fastening band, 5, pressing plate.
Embodiment
Safeguard structure at a kind of bridge expanssion joint as shown in Figure 1, presets in two sections of seaming position preformed grooves 1 of bridge
There is telescopic device 2, and telescopic device 2 is located at gaping of joints position and is provided with two fishbacks 3, middle and lower part is embedding between two fishbacks 3
Enter to be provided with rubber fastening band 4, i.e., 4 one end of rubber fastening band is embedded into sides adjacent fishback 3 groove of itself, and the other end is embedding
Enter into another fishback 3 groove of itself；
Wherein, rubber fastening band 4 blocks the gaping of joints of telescopic device 2 completely；Two fishbacks 3 are closed with rubber fastening band 4
Polyurethane is filled with the recess region enclosed, and will optionally be located at bridge central region in filled polyurethane and be higher than two
Border region, can so form an inclined-plane diversion trench；
Further, rubber fastening band 4 is W type rubber fastening bands；
The top of telescopic device 2 is provided with for preventing the polyurethane of filling from protruding from the pressing plate 5 of bridge upper end face, and is pressed
Plate 5 is individually fixed on the left of 2 top clearance of telescopic device and on the right side of top clearance for two, this mechanism is mainly prevented with pressing plate 5
Filler polyurethane dilatancy largely protrudes from bridge surface；
Further, two fishbacks 3 are Multilayer-tooth fishback, each layer relative to tooth form into groove in it is one embedded
Rubber fastening band 4, on above-below direction per two neighboring rubber fastening band 4 between be filled with polyurethane in gap, secondary structure is main
Ensure the waterproof effect of multilayer, while ensure that influence of the construction stretch deformation to waterproof effect.
Using the utility model of above-mentioned technical proposal, overall structure is simple, passes through fishback 3 and rubber fastening band 4
Assembling structure forms a groove for being used for filling polyurethane, and stabilized seal, the arrangement of whole device are formed after filling polyurethane
Step is simple, and drainage effect is good, and due to being that filling sealing has extraordinary protective effect for lower part, subtracts significantly
Later period maintenance frequency is lacked.
The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form
Limitation, although the utility model has been disclosed with preferred embodiment as above, but be not limited to the utility model, it is any ripe
