Description

{WATERPROOF COUPLING STRUCTURE FOR EXPANSION JOINT DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a waterproof coupling for an expansion joint, and more particularly, to improve the functionality of a waterproof coupling of a bridge expansion joint by improving the structure of a waterproof coupling

The structure of the bridge expands and contracts with temperature change and load. Therefore, the upper structures (bridges) of bridges constructed over a certain length have appropriate spacing (usually called "bridges") for every given length.

The expansion joint of the bridge top plate is installed. At this time, since the bridge top plate is divided into a vehicle bridge top plate on which the vehicle runs, and a bridge top plate on which a person hangs around the vehicle bridge top plate with a step, the expansion joint is also installed.

In the case of a bridge expansion joint, when the width of the bridge top plate is longer than the length of the expansion joint, the expansion joint is used in the longitudinal direction. At this time, a watertight coupling is provided between the interconnecting expansion joints of the bridges.

As a conventional example of such a waterproof coupling, Japanese Patent No. 909276 discloses a waterproof coupling in which a bent portion is formed on the outer surface of the fitting portion of the waterproof coupling and a seat portion is formed on the inner diameter of the elastic member (drainage sheet) Has been proposed.

However, according to the above-mentioned prior art, the bending portion of the waterproof coupling is merely seated on the elastic member, so there is a limit in the airtightness. As time elapses, lifting of the seat portion occurs and the waterproof coupling and the elastic member Leakage occurs through a gap between the sheets.

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the problems of the prior art described above, and it is an object of the present invention to provide a structure in which a state of engagement between a drainage sheet and a waterproof coupling, The purpose is to prevent the occurrence.

In order to achieve the above object, according to the present invention, there is provided a waterproof coupling installed at a connection portion between drainage sheets of an expansion joint device, wherein the waterproof coupling has a flange insertion groove into which a flange portion formed at the end portions of the drainage sheets at both sides can be inserted ; And the waterproof coupling is formed with a fastening hole for bolt fastening at a position corresponding to the passage formed in the flange portion.

The waterproof coupling of the present invention can maintain a stable state of engagement with the end of the drainage sheet on the connection portion of the expansion joint, thereby improving airtightness and preventing the leakage of rainwater.

8 is a cross-sectional view of a waterproof coupling according to a third embodiment of the present invention and an enlarged view of the main part thereof.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a waterproof coupling structure according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG.

The expansion joint device according to the present embodiment has a structure divided into an upper frame 30 and a lower frame 40. A drainage sheet 10 is press-fitted between an upper frame 30 and a lower frame 40 do.

At this time, the waterproof coupling 20 is fastened to the connection portion between the drainage sheets 10. In the present invention, the flange portion 11 is integrally formed at the end of the drainage sheet 10 in the form of a vertical wall, The waterproof coupling 20 is formed with the flange insertion groove 21 into which the flange 11 formed at the end of the drainage sheet 10 on both sides can be inserted.

At this time, the waterproof coupling 20 is formed with a fastening hole 21a for fastening the bolt 21b at a position corresponding to the passage 11a formed in the flange 11.

The waterproof coupling 20 preferably has a "V" or "U" shape similar to that of the flange portion 11.

The protrusion 10a protruding to the outside of the flange 11 is formed at the end of the drainage sheet 10 to prevent a gap between the drainage sheets 10 on both sides from occurring.

Hereinafter, the operation and effect of connecting the drainage sheet using the waterproof coupling according to the present invention will be described.

The waterproof coupling 20 of the present invention is fastened to the connection portion of the drainage sheet 10 in the process of constructing the expansion joint device, so that leakage of the connection portion can be prevented.

That is, when the waterproof coupling 20 is fastened, the both flange portions 11 provided at the connection portion of the drainage sheet 10 are simultaneously inserted into the flange insertion groove 21, The bolt 21b is fastened to the tube 11a and the fastening hole 21a so that the waterproof coupling 20 can be stably fastened.

Since the waterproof coupling 20 is fastened as described above, the connection operation of the drainage sheet 10 can be performed quickly and easily, and the waterproof coupling 20 of the connection portion of the drainage sheet 10 is formed, Can be prevented.

6 and 7 illustrate a waterproof coupling structure according to a second embodiment of the present invention. In the waterproof coupling 20, the two side flange portions 11 inserted into the flange insertion groove 21 are partitioned A partition wall 22 for partitioning the partition wall 22 is formed on the upper surface of the partition wall 22 and a urethane layer 22a are formed.

Since the flange portion 11 of the drainage sheet 10 is individually mounted on the side flange insertion grooves 21 divided by the partition wall 22, the contact between the flange portions 11 So that the occurrence can be prevented.

Particularly, since the contact area with the side flange portion 11 is increased by the partitioning wall 22, the coupling force is increased, and the watertightness in the interior is improved, thereby increasing the leakage prevention effect.

In addition, it is understood that the protrusion 10a is prevented from being crumpled by the urethane layer 22a, thereby preventing the leakage phenomenon from being maximized.

8 shows a structure according to a third embodiment of the present invention. The partition wall 22 is provided with a pair of pressers 23, 24 (not shown) for pressing the flange portion 11 inserted into the both- And an elastic spring 25 for resiliently supporting the pressurizing holes 23 and 24 is formed in the partition wall 22 and a supporting blade for holding the center of the elastic spring 25 26) is configured in the interruption section.

With this configuration, the flange portions 11 inserted into the flange insertion grooves 21 are pressed by the pressurizing holes 23 and 24, so that the coupling force of the waterproof coupling 20 can be further increased .

In addition, since the flange portion 11 to be pressed can improve the adhesion with the inner wall surface of the waterproof coupling 20, the watertightness is improved.
