Abstract
The utility model belongs to the section of detail in paving faces for a road and a bridge, particularly an expansion device of a collision-proof wall for a road bridge. The utility model mainly comprises a fixed plate and a connecting plate which are connected and installed by connecting elements which are arranged on the outer side of the connecting plate. The utility model solves the problem that the prior art can not satisfy the way that a collision-proof wall can correspondingly adjust according to the expansion and the contraction of a road bridge. The utility model has the advantages of strong integrity, reliable antiseep performance and reliable anti-collision performance, and the utility model can satisfy requirements, such as the expansion, the contraction and the displacement of a bridge in all directions.
Description
The utility model belongs to the thin portion in paving of road, bridge, is meant the crashproof wall stretching device of a kind of highway bridge especially.
Road, the crashproof wall in the bridge outside cause the surface that telescopic variation takes place because of climate changes at present, thereby the shock resistance of crashproof wall body of wall is descended.
The purpose of this utility model is to provide a kind of stretching device that can be used with road, bridge-collision-avoidance wall to overcome the deficiency that prior art exists.
Overall structure of the present utility model is:
The crashproof wall stretching device of highway bridge, it comprises the junction plate (4) that is assemblied on the connection rod member (3), and elasticity is connected in the connecting elements (2) between adjacent junction plate (4) and fixed head (1) or junction plate (4) and the junction plate (4).
Other structures of the present utility model also have:
Connect rod member (3) end bent and be block-shaped protrusion.
Accompanying drawing of the present utility model has:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the lateral view of Fig. 1.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
The overall structure of present embodiment as shown, be an integral body by connecting elements (2) resilient engagement between wherein adjacent junction plate (4), the fixed head (1), connecting elements (2) end cross-sectional is " people " font, the connection rod member (3) that is arranged at fixed head (1) both sides connects with crashproof wall tight fit, connecting elements (2) end and bridge extension joint main body are bonding, and the quantity that can regulate junction plate (4) and connecting elements (2) during use as required is to control flexible scope.
The obtained technological progress of the utility model is:
Adopt the road, the bridge-collision-avoidance wall that use with this matched with devices can satisfy its bridge, the flexible displacement of highway Each side need, antiseep and crashworthiness are reliable, globality is strong.
Claims (2)
1, the crashproof wall stretching device of highway bridge it is characterized in that it comprises the junction plate (4) that is assemblied on the connection rod member (3), and elasticity is connected in the connecting elements (2) between adjacent junction plate (4) and fixed head (1) or junction plate (4) and the junction plate (4).
2, device according to claim 1 is characterized in that connecting rod member (3) end bent and is block-shaped protrusion.
