Description

Separable jointless joint device and instituting method

The present invention relates to an expansion joint device which is installed at a part connected to the construction of a road or a bridge, and which can be adapted to the expansion and relaxation of a road or a bridge while allowing comfortable driving to a vehicle traveling on the road. The present invention relates to a detachable expansion joint device and a construction method thereof, which allow expansion and expansion of the expansion joint device up and down so as to be firmly and easily installed.

In the case of roads or bridges, it is customary to install expansion joints made of expansion and contraction at the connecting part, which is the connection part, which is used for thermal expansion and contraction of roads or bridges (slabs on the top) according to the temperature difference between one day of crossing or winter This is to absorb this, and expansion joints (Expansion Joint) or a part of the body is also embedded in the concrete joints (AL Joint) and a plurality of beams (KSB Joint) and expansion polymer (KSB Joint) Joinless Joint Filled with Elastomeric Polymer and NB Joint Using Body with Metal Insert in Rubber Material, Mono Cell Joint and Engraving Similar to but flexible transflex joint (TF joint) and finger joint (F) Inger Joints) have been developed, and the expansion joints currently used may have cushions to allow the vehicle to run comfortably on high speeds along with the expansion and contraction of the expansion joints. It is required, and more advanced joints are required to provide a structure that prevents the construction of the edge (Edge), which is the connection portion of the road or bridge.

Therefore, various types of joints have been researched and developed in order to meet the above demands, for example, 'Road Joint Expansion Joints and Installation Method' of Patent No. 135948, which is a registered patent, and my own improved registration design. It is a 'road joint expansion joint device' of the Korean Utility Model Registration No. 140845, the latter of which is formed by opposing a pair of crank-type plates and opening a three-dimensional sealing rubber between the plates and installing them to be supported by the enemy. U.S. Patent No. 4,359,295 has provided the most classic expansion joint device, and Japanese Patent Application No. 51-74321 of the sealing rubber (expanded rubber material) which is opened between the pair of plates in particular. Although the specific shape is described, these are all-integrated expansion joint devices as described above. The specific technique is omitted because it is different from the purpose to be achieved, and in the 'concrete reinforcing structure of the expansion joint part' of the utility model registration application No. 97-26882, which is designed by the applicant, nothing is placed on the side of the anchor supporting the expansion joint device. In order to improve the bearing capacity by adding a special device in the shrinkage mortar, I applied the application method of 'Joinless Joint Construction and Joint Anchor' in my patent application No. 95-5049 and my other utility model application 98-21365 'anchor fixing structure of expansion joint device' is to make the anchors to be easily connected to each other by a specific shape to be embedded in the concrete three-dimensional to improve the bearing capacity, the invention and the invention is strictly in accordance with the present invention It is different in the sense, and it is the same as the present invention and its purpose in the application of utility model registration No. 99-381 There is a 'improved TIF joint' of No. 2 (filed March 10, 1999), which is made of rubber having excellent elasticity as shown in a perspective state in FIG. 6 and a cross-sectional state in FIG. A joint body 1 having a rubber plate 11 in which a drawing groove for drawing is formed and a reinforcing iron plate 12 of metal material is inserted into an upper surface and a side surface of the rubber plate 11, respectively; A finishing angle (3) strongly bound to the concrete (6) at the lower end of the joint body (1) of the opening 61 cut to a predetermined size as a connection part such as a bridge on which the joint is installed; Sealing rubber (2) of the rubber material which is integrally interposed between the joint body (1) and the closing angle (3) between the whole body; Consisting of the joint body 1 is made of a fastening bolt 13 is inserted into the closing angle (3) side of the reinforcing iron plate 12 of the joint body (1).

Therefore, the rubber plate 11 serves as a road surface to ensure a comfortable running on the traveling vehicle, and furthermore, the rubber plate 11 is reinforced with a reinforcing steel plate 12 to support the shock load of the traveling vehicle to prevent damage to the rubber plate 11. It guarantees durability by giving, and the concrete (6), which is poured into the opening (61) and re-cured, is finished with a finishing angle (3) at its upper end, so that the most vulnerable edge is reinforced with a metal called the finishing angle (3). It is not easy to destroy or drop concrete 6 due to the structure, and reinforces the structure connected from the reinforcing steel plate 12 to the reinforcing bar 5 without using the 'L' anchor bolt 41. Since the connection with the iron plate 12 is also directly connected by a short fastening bolt 13 without employing a method such as welding, heat deformation can be prevented in the rubber plate 11, the reinforcing steel plate 12, or the like. Bonding strength is temporarily bonded to prevent thermal deformation Compared to the level, the binding force can be solidified. Especially, since it is not an 'L' shaped anchor bolt (41), there is no moment, so that the joint does not sit down easily due to external load, and the finishing angle (3) It is inserted over the entire length of the opening 61 can adjust the amount of the fastening bolt 13 according to the support load any number, so the support force is also superior.

However, the above-mentioned conventional design is a dedicated type that can be applied only to a joint of a specific shape called a reflection type joint. For example, the lower surface of the main body is easy to install when it matches the boundary line between concrete and asphalt, so the lower surface is preferably formed in a straight line. And, if the lower surface of the main body is inclined or includes a special shape, there is a problem that it is not easy to change the shape of the finishing angle located below and to change the installation specification accordingly.

The present invention has been researched and improved in view of the above-described problems, and the present invention has been completed in order to shorten the air and reduce the installation cost by securing a solid supporting force while being easily applied to any type of joint. This will be described in detail with reference to the drawings as follows.
