That is, the present invention is installed in the rubber rail 6 by installing a drainage tank 4 which can be slid in the guide casing 5 at the end of the rubber rail 6 of the expansion joint to expand and contract the stiffeners constituting the bridge. Various foreign materials such as sand and the like can be quickly discharged and drained together with rainwater, and the measuring tank 10 is installed in the drainage tank 4 so that the inspector can easily check and check the expansion and contraction of the chess. By doing so, it can greatly help bridge maintenance and repair.

Description

Catch basin and counter attached flexible coupling for bridge}

The present invention relates to an expansion joint device for bridges in which drainage tanks and measuring instruments are installed. More specifically, foreign substances such as sand remain between rubber rails of various shapes constituting the expansion joint device for bridges, which shortens the life of the rubber rail. It is to provide bridge expansion joints equipped with drainage tanks and measuring instruments to make it easier to measure the degree of expansion and contraction of bridges by season. will be.

Conventionally, when constructing bridges, one or more rubber rails are installed between beams and constituting the bridges in order to statically absorb relative displacement due to seasonal temperature changes, wind, earthquakes, etc. Extension joints for bridges are being constructed.

The rubber rail and the beam constituting the expansion joints for the bridge are bent upward at both ends and fixed to the railing side. In the case of the conventional expansion joints for the bridge, sand or various types scattered into the air by a vehicle passing through the bridge When foreign matters are laminated on the rubber rail, not only the rubber rail is stretched but also the rubber rail life is shortened.The rubber rail is bent upward so that the drain is not smoothly drained. The development of devices and the like was desperately desired.

Accordingly, the present invention is to provide a bridge expansion joint device of a new configuration that can eliminate the problems of the bridge expansion joint applied to the existing rubber rail as described above,

In particular, the drainage means is installed in the expansion joint device for bridges, and the drainage is made quickly with foreign matter such as sand stacked on the rubber rail, and the measurement means is installed to easily check the expansion degree of the chess with the naked eye. The present invention has been completed in view of the technical problem of the present invention in providing an expansion joint device for a bridge.

Figure 1 is a perspective view showing the expansion joint device (1) for the bridge provided by the present invention, Figure 2 is an exploded perspective view thereof, Figure 3 is a side cross-sectional configuration of the same, and the present invention in detail with the above drawings Same as

Bridge expansion and contraction apparatus (1) provided by the present invention is slidably installed on the neighboring railing (2, 3) and the drainage tank (4) formed with a drain pipe (4a) at the bottom, and the drainage tank (4) ) Is fixedly installed so as to correspond to the guide rails (5) on the handrails (2, 3) that can guide them when the slide is made along the expansion of the chessboard, the front of the drain (4) is a rubber rail ( 6) and the end of the beam 7 form an opening 8 which is inboard mounted.

In addition, an upper portion 9 also forms an opening 9 so that rainwater and the like can be quickly drained from within the drainage tank 4 when the rainwater falls into the drainage tank 4.

Of the rubber rail 6 and the beam 7 mounted on the opening 8, beams 7 at both ends are fixed to the sump 4 and the guide casing 5, respectively, and beams 7 at both ends. The rubber rails 6 fixed between the phases allow the rubber rails 6 to be stretched from side to side in accordance with the expansion and contraction of the chessboard between the openings 8.

On the other hand, the measuring means 10 is provided between the opening 9 of the upper part of the drainage tank 4, and the opening 8 of the front surface.

That is, the measuring means 10 slides the ruler 12 on the guide rail 11 fixed to the drainage tank 4, and then fixes the ruler 12 with the bolt 13, and visually adjusts the scale of the ruler 12. Corresponding guide casing (5) is formed so that the check hole 14 is formed so that the bridge checker can easily check the degree of expansion and contraction of the left and right chessboard.

The bridge expansion joint device 1 of the present invention, which can be configured as described above, is installed between the railings 2 and 3 of the bridge constituting the bridge as shown in FIGS. 4A and 4B, and has a rubber rail 6 having various shapes. Various sand, foreign matter, and rainwater stacked on the) can be quickly discharged and drained, and the degree of expansion of the chess can be easily checked by the naked eye, and the operation thereof will be described in more detail below.

Various sand or foreign substances dropped on the rubber joints 6 for expansion joints installed between the upper and the adjacent chessboards move along the rubber rails 6 having a predetermined gradient toward the railings 2 and 3 by rain water. And, the end of the rubber rail (6) is located in the drainage tank (4) so that sand and foreign matter, rainwater flows into the drainage tank (4) is quickly drained through the drain pipe (4a).

Rainwater flowing down from the top of the handrails 2 and 3 is also introduced into the drainage tank 4 through the opening 9 in the upper part of the drainage tank 4 to quickly drain the water through the drainage pipe 4a. When the interval between the chessboard is stretched according to the temperature change, etc., the drainage tank 4 of the present invention is guided to the guide casing 5 so as to be slidable from side to side. Will be able to drain the rainwater is smoothly.

And the scale of the expansion of the chess can be quickly visually confirmed through the measuring hole 14 the scale of the ruler 12 constituting the measuring means 10 installed on the drainage tank 4 and the guide casing 5 The bridge can be used to maintain and repair bridges.

As described in detail above, the expansion joint for a bridge (1) provided with a drainage tank and a measuring instrument provided in the present invention has various shapes, which are one of the constituent members of the expansion joint for mutual expansion and contraction of the chucks constituting the bridge. By installing the drainage tank 4 at the end of the rubber rail 6, various foreign matters such as sand stacked on the rubber rail 6 can be quickly discharged and drained together with rain water, and the drainage tank 4 has a measuring means. By laying (10), the inspector can easily check and check the expansion and construction of the chess by visual inspection, which can greatly contribute to the maintenance and maintenance of the bridge.
