The present invention relates to a bridge support structure, such as a bridge or bridge, and a bridge support disposed between the bridges to support the bridges flexibly, and in particular, an elastic pad disposed between the lower plate and the upper plate mediates a separate fastening member. The present invention relates to an integrated seismic elastic support fixed to the lower plate and the upper plate.

As is well known, the bridge bearings may be formed of elastomeric bridge bearings and spherical bearings, monopot-type bearings, and multiport bridge bearings, depending on the shape of the pad. -Type Bearing).

Among them, the use of an elastomeric bridge bearing is increasing due to its simple structure, easy manufacture, and low cost.

Figure 1 shows the most common elastomeric bridge support, according to the bottom plate 10 is installed in the bridge support structure 100, such as alternating or pier; The elastic pad 31 formed in a circular, elliptical, or polygonal column shape, and a plurality of metal flat plates 32 formed at regular intervals on the elastomer 31, are placed on the lower plate main body 11. ) And; Installed on the bridge 200, it is formed on the elastic pad 30 to form a structure consisting of a top plate 20 which is elastically supported. However, in the case of the conventional elastomeric bridge support, a method for preventing the positional movement of the elastic pad 30 is not devised, and the elastic pad 30 is externally connected in the process of installing the elastomeric bridge support. Due to the interference of the lower plate main body 11 and the upper plate main body 21 is not fixed to the central position, the position is released, or the elastic pad 30 to accommodate the horizontal displacement of the upper plate 20 after installing the elastomeric bridge support This results in a problem of dislocation from the home position. In addition, the elastomer pad 31 constituting the elastic pad 30 is deformed in the process of accommodating the horizontal displacement of the upper plate 20 after the elastic pad support is installed. There is a problem that a gap is generated between the lower plate 10 or between the elastic pad 30 and the upper plate 20. Thus, between the elastic pad 30 and the lower plate 10, or between the elastic pad 30 and the upper plate ( If a gap is generated between 20), the ground area between them is reduced, which causes a greater deviation of the position of the elastic pad 30.

To solve this problem, as shown in FIG. 2, the bracket 40 is fastened to the lower plate main body 11 through a separate fastening member 51 such as a bolt to prevent the positional deviation of the elastic pad 30. Elastomer-type bridge supports with reinforced beams are proposed. According to this, since the position of the elastic pad 30 is prevented by the bracket 50 installed on the lower plate main body 11, the problem that the elastic pad 30 is separated from the correct position is not caused.

However, as shown in FIGS. 1 and 2, the detachable elastic support to which the elastic pad 30 is simply inserted and fixed between the lower plate 10 and the upper plate 20, the elastic pad 30 is the lower plate 10. And the upper plate 20 is mounted on and supported by the elastic pad 30, that is, the lower plate 10 and the elastic pad 30 and the upper plate 20 are not fixed to each other. When the vibration is generated in the left and right direction or up and down direction, since the lower plate 10, the elastic pad 30 and the upper plate 20 is free to move with each other, the seismic function can not be expected in any case.

As shown in FIGS. 3 and 4, an integrated shockproof elastic support in which the lower plate 10, the elastic pad 30, and the upper plate 20 are sequentially fixed to each other has been proposed, which will be described in more detail as follows.

The conventional integrated shockproof elastic bearing shown in FIG. 3 is composed of an elastomer 31 having a circular, elliptical, or polygonal pillar shape, and a plurality of metal plates 32 formed at regular intervals on the elastomer 31. On the lower surface and the upper surface of the pad 30, the lower fastening plate 33 and the upper fastening plate 34 in the form of flat plates are fastened and fixed respectively through separate fastening members 51 and 52, and these lower fastening plates 33 ) And the upper fastening plate 34 are fastened and fixed to the upper surface of the lower plate body 11 and the lower surface of the upper plate body 21 via separate fastening members 53 and 54, respectively. In the present embodiment, the elastic pad 30 is the lower plate body 11 and the upper plate body () through the lower fastening plate 33 and the upper fastening plate 34 and the separate fastening members (51, 52, 53, 54). 21 is firmly fastened and fixed, not only the positional deviation of the elastic pad 30 is prevented, but the seismic function is exerted by the elastomer 31 constituting the elastic pad 30. However, in this embodiment, in order to fix the elastic pad 30 to the lower plate body 11 and the upper plate body 21 by using the lower fastening plate 33 and the upper fastening plate 34, a plurality of fastening members 51. Since each component must be fastened and fixed by using 52, 53, and 54, work is not only cumbersome and difficult, but also causes a large labor load and threatens worker safety.

In order to solve this problem, an integral seismic resilient bearing as shown in FIG. 4 has been proposed. As a result of the integrated seismic resilient bearing, a plurality of metal plates 32 are integrally molded to the elastomer 31, and the bottom metal plate 32a and the top metal plate 32b are exposed to the outside of the elastomer 31, The lower fastening plate 33 and the upper fastening plate 34 in the form of flat plates are bonded to the lowermost metal flat plate 32a and the uppermost metal flat plate 32b through the iron plate adhesive, respectively, and the lower fastening plate 33 and the upper fastening plate are respectively attached. The plate 34 is fastened and fixed to the upper surface of the lower plate body 11 and the lower surface of the upper plate body 21 via separate fastening members 53 and 54, respectively. According to the present embodiment, the lower fastening plate 33 and the upper fastening plate 34 are respectively disposed on the lowermost metal plate 32a and the uppermost metal plate 32b exposed to the outside of the elastomer 31 through the steel plate adhesive. Since it is adhesively fixed, the structure of the integrated shockproof elastic bearing is simplified, and when the integrated shockproof elastic bearing is constructed, the fixing operation of the elastic pad 30 in the field is simplified (unlike the embodiment shown in FIG. 3). The lower fastening plate 33 and the upper fastening plate 34 do not need to be fastened and fixed to the lower surface and the upper surface of the elastic pad 30 through the fastening members 53 and 54}. However, in this embodiment, an iron plate adhesive is applied to the lower fastening plate 33 and the upper fastening plate 34, or the lower metal plate 32a and the uppermost metal flat plate 32b, and the lower fastening plate 33 And the upper fastening plate 34 to be adhesively fixed to the lowermost metal flat plate 32a and the uppermost metal flat plate 32b exposed to the outside of the elastomer 31, which makes manufacturing considerably cumbersome and greatly reduces productivity. The work environment was also greatly degraded.

In this regard, the present invention has been made to solve the above problems, and its object is to provide an integrated vibration-resistant elastic bearing having a simple structure and easy manufacturing.
