Description

An apparatus for protecting a bridge bearing

The present invention relates to a bridge bearing protection device, in particular, by installing a protective material of the transparent material around the bridge bearing mounted on the bridge surface of the bridge or bridge to prevent the bridge bearing from easily corroded or failure caused by foreign matter Of course, the present invention relates to a bridge bearing protection device that allows an administrator to easily check whether there is a failure of the bridge bearing with the naked eye and take prompt action.

A general bridge is a general term for the structure that connects roads when there is a place that impedes the function of rivers, valleys or other roads. Bridges, footbridges, and viaducts (hereinafter referred to as bridges) may be used. It is divided into concrete bridge, steel bridge (steel bridge) and wooden bridge depending on the material used for the main structure.

5 is a view illustrating an example of a bridge generally used in the related art. The configuration thereof is as follows.

Shifts 100 located at both ends of the bridge and connecting the bridge and the road, Piers 101 installed on the ground to support the lower part of the upper plate 102, and the bridges 100 and pier 101 or pier The upper plate 102 is placed between the 101 and the piers 101.

In particular, the bridge bearing 200 supporting the lower portion of the upper plate 102 is mounted on the upper surface of the shift 100 and the bridge 101, the bridge bearing 200, as shown in FIG. Lower bridge support 201 mounted on the alternating surface 103 of the shift 100 and the bridge 101, upper bridge support 202 mounted on the lower surface of the upper plate 102, and the upper and lower bridge support The roller 103 is mounted between the 201 and 202, and the elastic rubber 204 mounted on the upper surface of the upper bridge support 202 serves to mitigate shock and vibration.

However, in the related art, a rubber casing was applied to the outside of the bridge bearing to block moisture, but moisture generated in the rubber casing was not discharged to the outside, thereby promoting corrosion of the bridge bearing.

In addition, by using the rubber casing of the opaque material, there was also a problem that the administrator can not check the operation state of the bridge bearing with the naked eye from the outside, and can not take prompt action in the malfunction state.

Accordingly, the present invention has been invented to solve the above problems, by mounting a protective device around the bridge bearing mounted on the bridge surface of the bridge or bridge, preventing the flow of water and foreign substances from the outside to support the bridge It is an object of the present invention to provide a bridge bearing protection device that can prevent the easy operation or corrosion caused by foreign matter.

In addition, by making the protective device transparent, there is also an object to allow the administrator to easily check the operation state of the bridge bearing with the naked eye.

In addition, by installing a vent to allow the air to dry inside the protective device and the internal moisture to be discharged to the outside, there is also a purpose to prevent the components of the bridge support from being corroded by the internal moisture. .

It is also intended to facilitate installation and disassembly, thereby facilitating repair in the event of a failure of the bridge bearing.

The present invention for achieving the above object is in a conventional bridge bearing; First and second lower quadrangular frames surrounding the lower bridge support and separated in a diagonal direction, The first and second upper and lower parts enclosed around the upper bridge support and separated in a diagonal direction are relatively smaller than the lower rectangular frames. A body comprising a rectangular frame, an inclined base connecting the corner portions of the first, second, upper and lower rectangular frames to each other, and a transparent plate mounted between the inclined bases; Upper and lower clips mounted on the outer side of the upper and lower rectangular frames, each of which comprises a U bolt, a pressing plate, and a nut; It is characterized in that the rubber pad is attached to the upper end of the upper square frame is in close contact with the bottom of the top plate.

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

1 is a view showing a mounting state of the bridge support protection device of the present invention, Figure 2 is a cross-sectional view taken along the line A-A of Figure 1, the configuration is as follows.

Lower bridge support 201 mounted on the alternating surface 103 of the shift 100 and the bridge 101, upper bridge support 202 mounted on the lower surface of the upper plate 102, and the upper and lower bridge support ( In the conventional bridge bearing consisting of a roller (203) mounted between the 201, 202, and an elastic rubber (204) mounted on the upper surface of the upper bridge support (201) to serve to mitigate shock and vibration;

The first and second lower rectangular frames 12a and 12b that surround the lower bridge support 201 and are separated in a diagonal direction, are mounted on the upper and surround the upper bridge support 201 and surround the lower rectangular frame 12. Slopes connecting the respective corner portions of the first and second upper and lower rectangular frames 11a and 11b and the first and second upper and lower rectangular frames 11a and 11b and 12a and 12b that are relatively smaller and separated in a diagonal direction. A body 1 composed of a base 13 and a transparent plate 14 mounted between the inclination bases 13;

Upper and lower clips (2, 3) are mounted on the outer side of the upper and lower rectangular frames (11, 12) and made of U bolts (21, 31), push plates (22, 32), and nuts (23, 33). and;

It is characterized in that it is made of a rubber pad (4) attached to the upper end of the upper square frame (11) in close contact with the bottom of the upper plate (102).

This will be described in more detail as follows.

In the center of the transparent plate 14, as shown in FIG. 3, the cover 5, which can be opened and closed and is formed with a plurality of ventilation holes 51, is mounted.
