       The present invention relates to a bridge device for bridges, and more specifically, through the bridge device connecting the bridge with the upper structure of the bridge to effectively absorb the displacement displacement and cyclic compressive load due to temperature changes while maintaining the coupling state of the bridge device It is to make it more robust to improve the safety of the bridge.

The bridge device is an intermediate lubrication device (Bearing Equipment) which is located at the contact point of the superstructure and the undercarriage of the bridge and transmits the load transmitted from the superstructure to the undercarriage without impact and safely adapts to earthquakes, winds, and temperature changes.

The bridge system adapts to the bridge load and absorbs the expansion and contraction so that the displacement of the bridge is not transmitted directly to the bridge or the bridge, and the buffering function of the bridge device allows the bridge to function smoothly and to prolong the service life.

In addition, the bridge system should determine its type and arrangement according to the type of superstructure, the length of the top plate or the piers, point reaction, durability, etc., especially in curved bridges, bridges, and special bridges. The format and placement should be determined.

The basic functions of such a teaching device are a support, a roll, and a sliding function.

The supporting function for performing the basic function of the chair apparatus as described above is to support the charge of the upper structure equal to the reaction force in the main structure of the lower structure, and the rolling (rotation) function is the self-weight and external load of the upper structure. It is a function that allows the rotation freely so that the restraint force caused by the rotation of the bridge end generated by It is a function to allow freely.

As a device suitable for the basic function of such a device, a very simple form that can be installed without any other components is an elastic chair (ELASTOMERIC SHOE).

The general elastic bridge device is composed of a configuration to increase the load capacity of the bridge by reinforcing the rubber layer including at least one steel plate between the upper structure (road layer) and the lower structure (pier).

Advantages include efficient support, high rotation angle, freely roll forward and slip, no lubricant injection, arbitrary shape, simple construction and economical effect. have.

Such a conventional teaching device is a pad 30 of a high-stretch material between the upper plate 11 and the lower plate 12, as shown in the Republic of Korea Patent Registration No. 0589129, the pad 30 is separated In the bridge bridge device 10 is configured to prevent the guide bracket 20,

The upper and lower plates 11 and 12 respectively form guide insertion holes 13 with nut holes 15 formed therein, and are fitted into the guide insertion holes 13 and bolt plates 23 formed at both ends thereof. On one surface, the guide bracket 20 is attached to the elastic guide 21 of the elastic material composed of a plurality of iron cores 24 therein, and fastened to the upper and lower plates 11 and 12 by bolts 14. Between the guide bracket 20 is configured to support the cushioning function and the pad 20.

However, in the bridge bridge device according to the prior art, the pad absorbing the displacement of the superstructure, such as the bending of the upper structure caused by the dead load and the live load and the drying shrinkage due to the temperature change in the upper structure is fixed by the guide bracket. As a result, the pad may absorb the shear load that is displaced in one direction, but there is a problem in that the displacement that occurs simultaneously with the pressing load of the upper structure cannot be absorbed effectively.

That is, the upper structure of the bridge generates a compressive repeat load of the upper structure at the same time as the moving displacement is stretched according to the temperature displacement, the bridge bridge device is stressed because the compressive repeat load and the displacement displacement is concentrated on the pad When the stress (moving displacement and compressive load) is transmitted to the pad, the guide bracket fixed to the upper and lower structures, which enables the movement in one direction to the pad, is separated or damaged. As a result of the phenomenon, there was a problem that the basic functions of the pad, the rolling, and the sliding function were not properly exhibited.

In particular, when the bearing, rolling, and slip stress loads are repeatedly concentrated on the pads, there is a problem in that the fatigue of accumulated pads causes aging and failure to function properly as a teaching device, thereby shortening the life of the teaching device.

In addition, the bridge device has a structure in which the upper plate and the lower plate is fixed to the bridge by bolts so that the displacement and compression loads generated in the bridge are transferred to the upper and lower plates through the bolts, so that the pad absorbs the final stress. It consists of a structure.

As such, the stress transmitted to the bridge device causes a shear phenomenon of the bolt as the stress is transmitted to the bolt having a weaker strength than the pad, thereby causing the bridge device to be separated or separated from the bridge.

As described above, when the fixed state of the bridge device is released from the bridge, there is a problem in that the point reaction force and durability of the bridge are dropped, which causes a serious danger to the safety of the bridge.

Therefore, the main purpose of the present invention is to combine the anchor socket in the shear prevention groove of the upper plate or the lower plate, the upper and lower plates and the anchor socket when the bearing, rolling, slip stress and crushing force occurs in the bridge under temperature change and compression repeat load It is to distribute and share the stress concentrated in the coupling means to maintain the fixed state with the support holder to maintain the fixed state of the bridge device in the bridge.

In addition, another object of the present invention is to close the bridge and the bridge device state even if the point reaction caused by the incident force caused by the flooding of the river by the escape of the anchor socket embedded in the concrete or mortar on the upper structure and the bridge To keep things going.

In addition, another object of the present invention is to couple the leveling means to the lower end of the anchor socket to easily adjust the horizontal height adjustment of the chair according to the fastening state.

In order to achieve the above object, the bridge device for a bridge of the present invention is a bridge device installed between a bridge to be bridged to support the lower structure of the upper structure and the upper structure,
