The present invention relates to an elastic bearing which is installed between the upper plate and the bridge of the bridge to receive the load and deformation of the upper plate. More specifically, the elastic bearing prevents the elastic bearing from being displaced due to repeated horizontal displacement applied to the elastic bearing. It is about a configuration which enables it.

The bridge has a structure that hangs the top plate on the bridge and the bridge and the top plate are in contact with the pier and the top plate for horizontal displacement due to the thermal deformation of the top plate caused by the dynamic load and temperature difference caused by the vehicle passing through the top plate of the bridge. Elastomeric bearings are provided to allow relative movement.

Since the elastic bearing receives horizontal deformation along with the vertical load, it has a structure in which steel plates and rubber are alternately stacked to support them.

In the conventional elastic support, the elastic support has a plate contacting the upper and lower portions of the elastic support in order to prevent deviation from the correct position in the event of repeated horizontal displacement, and the plate is joined to the anchor bolt embedded in the piers or the upper plate and then at the edge of the plate. The installation of the movement control bracket prevents the elastic bearings located between the plates from being displaced by the movement control bracket. Korean Patent Application No. 1995-36084, Utility Model Registration Application No. 2000-19647, Dong 2000-29262, There have been many known such as 2002-1873, 2003-4426.

However, the structure of the elastic restraint of the elastic support by the movement control bracket as described above, the elastic restraint of the part in contact with the separation prevention bracket is not free to deform, so that the function of absorbing the elasticity of the upper plate is reduced, and the upper and lower plates are Due to the need to be provided, the height of the elastic support should be as high as the upper and lower plates, and there are various problems such as complicated installation and increased cost, such as embedding anchor bolts and fixing plates.

The present invention has been devised to solve the above problems to form a groove into which the pin can be inserted into the bottom of the elastic bearing, and even in the piers where the elastic bearing is located at a position corresponding to the groove formed on the bottom of the elastic bearing. It is an object of the present invention to provide a configuration in which a groove is formed so that the pin does not leave its position by the pin even in horizontal deformation where the elastic bearing is repeated.

Another object of the present invention is to allow the elastic bearing to free the deformation over the entire height and to shorten the separation distance between the piers and the top plate.

Another object of the present invention is to simplify the installation structure of the elastic support and to reduce the manufacturing and installation costs.

The present invention for the above purpose, "an exact position preventing structure of the elastic bearing" is one or more, preferably perpendicular to the stretching direction of the upper plate on the bottom of the elastic bearing formed by integrally laminated thin steel plate and rubber Forming two grooves in the direction and forming a groove so as to correspond to the groove formed on the bottom of the elastic bearing on the upper surface of the bridge where the elastic bearing is to be placed, and connecting the groove of the elastic bearing and the bridge with a pin made of elastic material. Provide a configuration to fix the position.

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

Figure 2 is a cross-sectional view of the structure of the present invention elastic restraint prevention structure, Figure 3 is an exploded perspective view of the present invention, Figure 4 is another embodiment of the present invention.

As shown in FIGS. 2 to 3, the present invention is integrally formed by alternately stacking a thin steel plate 1 and a rubber 2 as in a general elastic support, and the molded elastic support forms a portion of the steel plate 1. Except for the rubber part, only 70% of the height of the elastic base can be modified.

At least one bottom surface of the elastic support 3 is formed, preferably two grooves 4 in a direction orthogonal to the stretching direction of the upper plate, but the number of grooves is not limited thereto.

Grooves 4 'having the same spacing and size are formed on the upper surface of the piers 5, on which the elastic bearings 3 are to be located, so as to correspond to the grooves 4 formed on the bottom of the elastic bearings 3, respectively.

An elastic pin 6 formed of a material having elasticity is inserted into the groove 4. 4 ′ formed on the bottom surface of the elastic support 3 and the upper surface of the piers 5 to be elastic even when the upper plate 7 is repeatedly stretched. The support 3 is prevented from moving out of position.

As long as the material of the elastic pin 6 is a material having some elasticity and strength, any material may be used, but steel or synthetic resin is preferable.

When the length of the elastic pin (6) is long, the deformation of the elastic support (3) may be restricted, and it may be difficult to replace the elastic support (3), so the length of the elastic pin (6) of the elastic support (3) It is preferable that the elastic pin 6 is not separated from the grooves 4 and 4 'according to the deformation.

4 is another embodiment of the present invention so that the elastic pin 6 does not damage the groove 4 'formed on the bottom surface of the elastic support 3 or the groove 4' formed on the upper surface of the piers 5. In this regard, the metal rings 8 and 8 'may be inserted into the openings of the resilient bearings and the pier grooves 4 and 4' to prevent the resilient bearing grooves from being torn or the grooves of the upper plate being damaged.

However, the rings 8 and 8 ′ inserted into the grooves 4 of the elastic support 3 may limit the deformation of the elastic support 3 when the length thereof is longer, so that the insertion depth is preferably as shallow as possible.

As described above, the present invention can make the elastic support prevent the deviation from the fixed position with a simple configuration, can lower the overall height of the elastic support, and the configuration is simple and easy to manufacture and install, so that the elastic support can be supplied at low cost. It has the effect of making it possible.
