The present invention relates to a joint device of the underground car sidewalk concrete structure, in particular, it is possible to the airtightness of moisture generated from the outside or inside, not only to prevent inequality of the concrete structure, but also easy to join the joint device It relates to a joint of a concrete structure that can maintain the airtight between the joints.

In general, the underground car sidewalk is formed of a box-shaped concrete structure, and is divided into several sections. That is, one section is constructed by placing concrete and curing the formwork to a predetermined length and length, and then the sections are divided by the planned length in such a way that they continue along the longitudinal direction so that the construction as described above is achieved. Doing.

And between the concrete structures of each section is interconnected by a water plate, the space portion is filled with a joint filter of a hard buffer, the joint filter end side is sealed with a water expansion index to prevent the phenomenon of leakage through the joint. The water-expanding agent absorbs water from both sides of the concrete structure and serves to seal the gap while expanding its volume.

However, the water-expansion index agent begins to harden gradually after about a year, and loses its function, that is, the ability to seal the gap and expand the watertightness by absorbing water, thus losing the ability to achieve watertightness. There was a problem that leaks occur at the site.

In addition, there is a problem in that water leakage is increased because a means for blocking moisture penetrating into the joint part from the inside of the concrete structure, moisture penetrating into the inside from the outside of the concrete structure, and moisture penetrating into the gap between the joint part are not provided.

In order to solve the above problems, Korean Patent Application No. 10-2001-0064052 filed by the present applicant has been proposed.

The registered patent comprises a first blocking plate and a second blocking plate of the same shape in parallel with each other at a predetermined interval to form a main body, and the filling space in which the joint filter is filled between the first blocking plate and the second blocking plate. It is formed, both ends of the filling space portion is sealed rubber expansion for maintaining airtightness, and formed a plurality of anchor bolts on the side of the first blocking plate and the second blocking plate, so that the coupling device is connected to the concrete structure have.

Here, the first blocking plate A and the second blocking plate B protrude in parallel to the first blocking plate and the second blocking plate in parallel to the side surfaces of the first blocking plate and the second blocking plate, so that the inner and outer concrete It is designed to block the flow of incoming water.

In addition, a flange and a plurality of support jaws are formed on the first blocking plate and the second blocking plate upwards so that the plurality of joint apparatuses can be connected and used, and in particular, a seal having an insertion groove formed up and down is formed on the first blocking plate. And attached to the top surface of the second blocking plate is configured to maintain the airtight.

However, the joint device made of the above configuration is possible to block the moisture generated from the upper, lower and left and right, but in other words, from the front and rear, that is, about the moisture generated from the side portion connected to the joint and the joint device There was a problem with no way to block.

In addition, the flange and the supporting jaw are fastened to the first blocking plate and the second blocking plate by welding or other fastening means to connect the joint device and the joint device, thereby increasing the work efficiency and cost according to the increase of the work process. Particularly, in order to form a seal having an insertion groove formed up and down, the first blocking plate and the second blocking plate of the joint apparatus are manufactured by protruding the second receiving plate more than the first blocking plate and the second blocking plate. As the second aberration plate is further protruded, there is a problem that a stable connection is not made when connecting the joint device.

In addition, the joint is to be installed to connect the concrete structure to a lot of flow of the vehicle, such as the underground car, the joint simply connected the joint to the concrete structure by anchor bolts, There is a problem that there is no provision for inequality that can occur between concrete structures formed on both sides.

The present invention is to shorten the work process by forming a connection packing formed of a simple third structure and the double-sided adhesive on the first barrier plate, the second barrier plate and the second barrier plate when connecting the joint devices to each other The purpose of the present invention is to provide a jointing device for a concrete structure that can lower the manufacturing cost, and can further secure the coupling of the jointing device by further forming a fastening groove in the third order plate and the connection packing.

Still another object of the present invention is to provide a joint apparatus for a concrete structure, which can prevent uneven settlement occurring between concrete structures connected by a dowel bar formed in the joint apparatus.

Still another object of the present invention is to provide a joint apparatus of a concrete structure capable of blocking the penetration of moisture by the third order plate and the connecting packing up, down, left, and right as well as before and after.

In order to achieve the above object, the joint device of the concrete structure of the present invention has a space portion formed between the first and second barrier plates of the same shape in parallel with a predetermined interval therebetween, and both ends of the space portion are elastic rubber. Of the underground sidewalk concrete structure having a plurality of anchor bolts protruded symmetrically from each other on the side surfaces of the second blocking plate and the first blocking plate and the second blocking plate which are formed to face opposite sides of the elastic rubber. In the joint apparatus, a third order plate which is bonded to the upper and lower sides of the first blocking plate, the second blocking plate and the second receiving plate by welding, so as not to cover the space portion and the elastic rubber of both sides; Protruding orthogonally to the side surfaces of the first blocking plate and the second blocking plate, the first blocking plate formed to support the third blocking plate and the side portions of the first blocking plate and the second blocking plate; The pieces are formed to face each other with welba and the front or back, or front and that makes up a connection packing forming a double-sided adhesive on the back.
