Description
Technical Field
The utility model relates to an expansion joint of making an uproar falls.
Background
A bridge expansion joint is defined as an expansion joint between two beam ends, between a beam end and an abutment, or at a hinge joint of a bridge, in order to meet the requirement of deformation of a bridge deck. The expansion joint is required to be freely telescopic in two directions parallel to and perpendicular to the axis of the bridge, and the expansion joint is firm and reliable, and when a vehicle runs, the vehicle is smooth and free of sudden jump and noise; the rainwater and garbage soil can be prevented from infiltration and blocking; the installation, the inspection, the maintenance and the dirt elimination are all simple and convenient. The existing noise reduction telescopic device is usually anchored by bolts, and the bolts are easy to loosen, fall off and damage and are inconvenient to use.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides a simple structure, reasonable, reliable, and intensity is high, and stability is good, the expansion joint of making an uproar falls of production that can effectively the noise reduction.
In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides an expansion joint of making an uproar falls, includes angle steel, the scalable hollow rubber seal tube of compression and dowel steel, the angle steel is provided with two, and two the right angle groove of angle steel is located the concrete layer of expansion joint both sides respectively, and the upper portion of angle steel is horizontal to be held the level setting with the bituminous paving on the concrete layer, the scalable hollow rubber seal tube level of compression sets up between the vertical end of two angle steels, the one end of dowel steel with the right angle groove welded fastening of angle steel, the other end and concrete layer's embedded bar welded fastening.
In a preferred embodiment of the present invention, a limiting steel plate is further disposed outside the longitudinal end of the angle steel.
In a preferred embodiment of the present invention, the two limiting steel plates at the longitudinal ends of the angle steel are flush with each other.
In a preferred embodiment of the present invention, the limiting steel plate is also horizontally disposed.
In a preferred embodiment of the present invention, the compressible and retractable hollow rubber sealing tube is located above the limiting steel plate.
In a preferred embodiment of the present invention, the diameter of the compressed and retractable hollow rubber sealing tube is larger than the width of the expansion joint.
The utility model has the advantages that: the utility model discloses simple structure, reasonable, reliable, intensity is high, and stability is good, the production of effective noise reduction.
Drawings
Fig. 1 is a front view of a preferred embodiment of the noise reduction expansion joint of the present invention.
Detailed Description
