The present invention relates to a expansion joint device for a bridge that allows the displacement and deformation to occur in the upper sleeve during the vehicle progress, more specifically, the components of the expansion joint device fixed to the upper sleeve (upper structure) In addition to improving the structure of the joint for easy assembly of the rubber plate to the in-joint, the structure of the connection part of the rubber plate is improved, and drainage holes are formed on the rubber plate to facilitate the rapid drainage of rainwater generated in the upper sleeve (upper structure). It relates to the invention.

In general, a bridge that a heavy vehicle passes through receives a heavy impact load due to the weight and movement of the vehicle.

The upper sleeve is displaced and deformed to prevent damage to the bridge (top plate and pier) due to the impact load and to promote safe driving. The displacement and deformation are expansion joints connecting the upper sleeve and the upper sleeve. Accepted by the device.

As described above, expansion joints that are stretched according to the displacement and deformation of the upper sleeve are variously conceived.

Among them, a typical expansion joint device includes a joint made of an anchor bar welded to reinforcing bars and welded to reinforcing bars, and an expansion joint member fixed at both ends to a fastening groove formed in the joint. Elastic rubber).

The expansion joint device configured as described above is to assemble the expansion joint member while the joint is fixed to the upper sleeve, so that the fixing part of the expansion joint member is fastened to the joint groove of the joint by using a tool manufactured to fit the expansion joint member. Push to assemble.

As described above, when the expansion joint member is coupled to the joint using a tool, the expansion joint member is damaged by the tool, and at the same time, the working space is narrow and the working time is long, and the expansion joint is a joint And the expansion joint member are simply assembled, so that foreign matter such as rainwater is easily mixed between the expansion joint member and the joint, and the life of the expansion joint member is shortened, and the life of the expansion joint member is shortened to the upper sleeve. Rainwater generated may leak through many unspecified areas, causing the reliability of contractors to be lowered.

Utility model registration No. 272166 is an expansion joint device designed to solve the disadvantage of the conventional expansion joint described above.

In the pre-registered invention, the fixing bolt is fastened so that the elastic joint member can be firmly fixed at the same time as providing a portion where both ends of the elastic joint member (elastic rubber) are fitted in the joint using a bending plate.

While the above-described pre-registered invention solves the above-mentioned disadvantages of the expansion joint device, there is not only a difficulty in the operation of pushing the expansion joint member from the side, but also the joints are positioned in the same line when a plurality of joints are installed in series. There is a lack of means to lay the joints side by side on the upper sleeve, the work takes a long time to install, the expansion joint member is installed in a simple surface contact state, the water leak in the connection part is inevitable, In the case of rain, rainwater falls into the glass of the vehicle driving down the elevated road, which hinders driving.In the conventional expansion joint member, there is no means for draining rainwater, so rainwater generated on the top plate cannot be drained immediately. This rainwater can cause a sliding accident. Was FIG.

The present invention was developed in order to solve the shortcomings of the expansion joint device of the pre-registered invention, the purpose of which is the vertical plate of the joint constituting the expansion joint device to facilitate the displacement and deformation occurring in the upper sleeve during vehicle progression When forming a plurality of joints on the upper sleeve by connecting the bracket to the upper sleeve, the connecting brackets are connected by connecting bolts, so that the joints can be easily connected and installed in parallel with each other. By inserting the hole formed in the shock absorbing part of the rubber plate into the bolt and then placing the tightening nut on the bolt while the separated configured angle is placed in the vibration noise absorbing part, the rubber plate installation can be easily performed. The upper slit in rainy weather due to the engagement of the connecting protrusion and the connecting groove It solves the conventional problem that the rainwater generated in the water leaks through the rubber plate connection part and at the same time, the rainwater can be drained through the drain hole formed in the rubber plate to prevent traffic accidents caused by the sliding of rainwater on the upper sleeve. It is to provide a expansion joint device for bridges.

The present invention for achieving the above object is anchored to the reinforcement of the frame of the upper sleeve (100) which is placed on top of the pier at the same time the concrete is poured buried anchor (12) the rear of the vertical plate (11) And a joint 10 formed of a plate 13 having a plurality of connecting pieces 13a intersecting with each other, and having a length corresponding to the length of the joint 10, and displacement of the upper sleeve 100. And rubber sheet having a stretching portion 32 is made to stretch and smoothly according to the deformation, the vibration noise absorbing portion 31 having a width and a thickness that can effectively receive the vibration, noise transmitted from the upper sleeve 100 In the bridge expansion joint consisting of 30,
The connecting bracket 15 is formed on the vertical plate 11 to facilitate side-by-side arrangement of the upper sleeve 100, and the vibration noise absorbing portion 31 of the rubber plate 30 is formed on the bottom of the flat plate 13. In the joint 10 in which the formed hole 31a and the bolt 14 into which the hole 21 of the separated angle 20 is fitted are formed, the surfaces facing each other so as to prevent the leakage of rainwater are formed. Connected by the 33 and the connecting groove 34, so that the rain water generated in the upper sleeve 100 to the expansion and contraction portion 32 is smoothly stretched in accordance with the displacement and deformation of the upper sleeve (100). It is achieved by the expansion joint device for bridges, characterized in that the assembly consists of the rubber plate 30 is formed with a drain hole (32a).
