Abstract
The utility model relates to a low position seal gum bridge wave type expansion gap, which is composed of a steel side plate (1), an anchoring fixed rib (2) and seal gum (3), wherein, the distance of the lowest point of the top arc of the seal gum (3) and a height mark plane (4) is less than and equal to 5 mm, when the position of the seal gum is reduced, the seal gum does not directly contact with wheels or the seal gum just slightly contact with wheels, but the seal gum can not be repeatedly rubbed and rolled by the wheels, and the bonding of the seal gum and the steel side plate can not be damaged for rubbing and rolling.
Description
The utility model relates to a kind of bridge expansion joint installation, exactly is a kind of low-level seal glue bridge wave mode shrinkage joint.
All the shrinkage joint need be set in the bridge construction, the past shrinkage joint of design makes vehicular traffic exist serious jumping car phenomenon.In order to overcome this drawback, the wave mode shrinkage joint that China designs voluntarily has been put to use on some high-grade highways and speedway, and is respond well.The wave mode shrinkage joint needs to load whippy fluid sealant in the shrinkage joint that is formed by the steel side plate.The end face of fluid sealant is the arc to recessed limit, and its minimum point is apart from about 3 millimeters of steel side plate end face (just the absolute altitude face is called on bridge floor or road surface in the following text).Just because of the position of fluid sealant is too high, and bear every day thousands of wheels stranding, rub, in day by day stranding, rub under the effect, fluid sealant is torn with the bonding of steel side plate, crackle during beginning gradually becomes the crack, and water, dust, foreign material etc. can fall into wherein, quicken the expansion in crack, finally cause fluid sealant to come off.Although the not aged deterioration of the quality of fluid sealant own than shortening dramatically the application life of expecting, has also influenced the total quality at wave mode shrinkage joint.
The utility model is intended to protect the bonding of fluid sealant and steel side plate by changing the position of fluid sealant, makes it does not rubbed with the hands, rub and destroy by wheel, increases the service life, and guarantees total quality.
The utility model is achieved in that and reduces the position of fluid sealant in the shrinkage joint, makes fluid sealant end face arc minimum point be lower than the absolute altitude face below 5 millimeters.
After the fluid sealant position reduces,, perhaps be slight contact, but will not rubbed with the hands repeatedly, rub, make the fluid sealant can be because of rubbing with the hands, rubbing and destroy with the bonding of steel side plate by wheel with directly contact of wheel.Facts have proved that be more than 3 times of high-order fluid sealant the application life of low-level seal glue.
Fig. 1 is the plane structure schematic diagram of bridge wave mode shrinkage joint when not watering the road surface as yet.
Fig. 2 is the position of high-order fluid sealant shown in the A-A section of shrinkage joint.
Fig. 3 is the position of the utility model fluid sealant shown in the A-A section of shrinkage joint.
Embodiment:
As shown in Figure 1, wave mode steel side plate 1 constitutes the wave mode shrinkage joint after horizontal, vertical some anchor ribs 2 are fixed.
As shown in Figure 3, filling fluid sealant 3 in the shrinkage joint, just fluid sealant 3 end face arc minimum points are apart from absolute altitude face 4-5 millimeter, and are perhaps lower.
Claims (1)
1, a kind of low-level seal glue bridge wave mode shrinkage joint is made of steel side plate (1), anchor rib (2) and fluid sealant (3), it is characterized in that: fluid sealant (3) end face arc minimum point is with distance≤5 of absolute altitude face (4) millimeter.
