Prefabricated modular hinge finger joint device for easy maintenance {Module Hinge-type Finger Joint}

The present invention relates to a finger joint device used for a bridge structure and the like, and more specifically, to a hinge structure rotatable finger portion in a conventional finger joint device used for bridges, etc. The present invention relates to a prefabricated modular hinged finger joint device that is easy to maintain and maintain a finger joint, and that can be manufactured at a low cost.

1 is a schematic perspective view of a finger joint device 100 as a conventional expansion joint generally used in bridges.

As shown in FIG. 1, a conventional finger joint device 100 as a stretch joint generally used in a bridge includes a finger portion 101 protruding in a sawtooth shape, and each of the finger portions 101. It is composed of a body 102 integrally with the finger portion 101 at the end. In the conventional finger joint device 100 described above, the finger portion 101 is interlocked with both sides of each other.

In order to install the finger joint device 100 as described above, after block-out the end edges of the upper structures 200 and 200 ′ of the bridges, the shrinkage is performed in the block-out part with the tension bolt 201 installed. The mortar is poured and cured, and the finger joint 100 is installed on the top of the mortar. At this time, in order to prevent foreign matter or sewage from flowing into the gap between the edges of the upper ends of the upper structures 200 and 200 ′, the bolt members 203 are used after the bending plates 202 are installed at the edges of both sides. By installing the waste member 204 made of waterproof rubber and the like. Reference numeral 205, which is not described in FIG. 1, is a reinforcing bar 205 for reinforcing the blocked-out part, and reference numeral 206 is a reinforcing bar 206 exposed at an end edge from the upper structure 200, 200 '.

In the case of the conventional finger joint device 100 as described above, there were the following disadvantages.

First, there is a disadvantage that machining is difficult. In the conventional finger joint apparatus 100, the finger portion 101 and the body 102 are integrated. Therefore, in order to manufacture the finger joint apparatus 100 as described above, the thick steel sheet should be cut and cut into a sawtooth shape by a method such as laser processing. However, since the steel plate used in the finger joint device 100 is a thick thick plate of about 40 mm to 55 mm, cutting and cutting the sawtooth-shaped finger part is not only a very precise work but also takes a lot of time to manufacture. Therefore, there is a problem that it takes a lot of time and cost to process the finger joint device 100 in which the finger portion 101 and the body 102 are integrated as in the prior art.

Second, it is difficult to treat the dirt, etc. flowing between the fingers. Even when the fingers 101 are interlocked with each other, dirt, such as garbage, flows into the gap between the fingers. Soil introduced in this way is collected in the bottom of the waste receiving member 204, it is preferable to remove such collected dirt. By the way, in the conventional finger joint device, the entire finger joint device must be removed in order to remove the dirt collected in the dirt receiver member 204. In addition, if the dirt receiver member 204 is damaged, the entire finger joint device must be removed as above to replace it. In order to remove and reassemble the finger joint device, it is necessary to control the passage of the bridge for a considerable time, and there is an inconvenience of lifting a heavy finger joint device.

In some cases, the finger joint device may be integrally formed over the entire lateral width of the bridge. In this case, the entire finger joint device may be replaced to remove dirt of a specific part or to replace the dirt receiver member. Lifting and removing and then installed again, the inconvenience is very large. Therefore, in the case of the conventional finger joint apparatus, the cleaning and replacement of the dirt collecting member 204 is hardly performed, and thus problems such as poor drainage have occurred.

Third, even if some fingers are damaged, the entire finger joint device has to be replaced. In the case of bridges, it is often the case that some fingers are damaged due to very large concentrated loads acting on parts of the finger joint device due to overloading vehicles or for other reasons. In this case, in the conventional finger joint apparatus, not only the damaged finger portion, but also all the intact finger joint apparatuses must be replaced, and accordingly, there is a problem in that the cost is high.

The present invention was developed to overcome the disadvantages of the prior art, specifically, the dirt accumulated between the finger joint device can be easily removed by a simple method, and in case the finger part is damaged, only the damaged finger part can be easily replaced. In addition, it is an object to provide a finger joint device of a new structure that can be easily manufactured to reduce the manufacturing cost.
