조립식 교량 충격 완화재{Stuff for mitigation impact a bridge of assembly type}Prep mitigation impact a bridge of assembly type

본 고안은 조립식 교량 충격 완화재에 관한 것으로, 보다 상세하게는 교각이나 우물통에 앵커볼트에 의해 직접적인 타설을 하지 않고, 충격완화재의 원형요철부와 또 다른 충격완화재의 원형요입부를 삽입 결합시키므로써, 강물의 수위변화에 따라 상기 교각이나 우물통에 이동 설치하여도 교각 및 우물통이 원상태로 유지되면서, 미관을 해치지 않도록 하며, 교량의 교각사이로 선박 항해시 교각 또는 우물통과의 충돌에 따른 선박 및 교각, 우물통을 보호하면서, 상기 선박에 탑승한 승객들의 인명피해를 방지하도록 한 조립식 교량 충격 완화재에 관한 것이다.The present invention relates to a prefabricated bridge shock absorber, and more specifically, by inserting the circular recesses of the shock absorber and the circular recesses of another shock absorber without inserting directly into the pier or well by anchor bolts. Even though the pier and the well are kept intact, even if they are installed and moved to the pier or the well according to the water level change of the river, the pier and the well when the ship sails between the bridge pier and the collision with the pier or the well and The present invention relates to a prefabricated bridge shock absorber that protects a pier and a well, and prevents damage to passengers on board the vessel.

일반적으로 해상이나 강에 설치되는 교량에는 선박이 항해하는 항로에 따라 그 부분이 통과되는 교각이나 교각을 지탱하는 우물통에 충격완화재를 설치하여 선박과 교각 및 우물통을 보호할 목적으로 종래에는 폐타이어를 와이어로 엮어 설치되는 경우가 간혹있었지만 상기와 같은 충격완화재는 장기간 동안 사용하면 와이어가 산화되는 결점이 있기 때문에 우기시에 물살에 의해 쉽게 절단되어 엮은 폐타이어가 분리되는 문제점이 있으며, 선박의 잦은 충돌로 인하여 와이어의 엮은 부분이 처짐이 발생되며, 폐타이어로는 선박이나 교각이 충격을 흡수할 수 없기 때문에 선박이 파손되어 인명피해가 있게 되며, 교각같은 경우에는 충격부분이 파손되는 문제점이 있다.In general, a bridge installed in a sea or a river has a conventional method for protecting a ship, a pier, and a well by installing an impact buffer in a well for supporting a pier or a pier where a portion passes according to the route of the ship. In some cases, the waste tire is woven with wire, but the above-described shock absorber has a problem in that the wire is oxidized when used for a long period of time, so that the waste tire is easily cut and woven by rain current during rainy season. Frequent collisions of wires cause sagging of the wires, and tires and ships can not absorb shocks due to waste tires, resulting in damage to the ships and damage to life. There is this.

이로 인해 상기와 같은 문제점을 해소하기 위하여, 도 3, 도 3a 및 도 4 에 도시한 바와 같이, 등록실용신안공보(등록번호 20-149829호)의 교량용 충격 완화재가 제안된바, 이의 구성을 살펴보면, 충격완화재(1)의 이면에는 교각의 곡선과 같은 만곡부(2)를 형성하고, 상기 충격완화재(1)의 양측의 내부로는 앵커공(3')을 갖는 보강철판(3)의 길이방향으로 삽입되도록 압출성형하며, 상기 충격완화재(1)의 전면의 양측에는 복수개의 앵커장공(4)을 천공하고 상기 충격완화재(1)의 중앙이 전면에는 길이방향으로 형성된 홈(5)에 야광물질인 페인트를 도색하는 도색부(6)가 형성되어 있으며, 상기 충격 완화재의 만곡부를 교각이나 우물통에 접촉시킨 상태에서 상기 충격 완화재의 양측에 형성된 앵커장공으로 앵커볼트(10)를 타정하여 부착고정시키므로써, 선박충돌시 충격완화재가 선박의 충격력을 흡수하므로, 선박의 파손을 최대한 방지하면서, 교각이나 우물통을 보호하는 장점이 있기는 하지만, 수위가 낮을 경우 교각을 지탱하는 우물통에 충격완화재를 앵커볼트로 체결하고, 수위가 높을 경우 교각의 높이까지 충격완화재를 설치하므로 충격완화재의 많은 낭비가 발생되는 문제점이 있으며, 상기와 같이 수위의 차이에 의해 각각의 우물통과 교각에 설치하지 않고, 우물통에 설치된 충격완화재를 분리하여 교각에 설치할 경우, 조립 및 분리작업이 매우 번거로우면서, 상기 충격완화재를 분리시킨 자리에 앵커볼트 타정자리가 형성되게 되어, 상기 타정자리에 물이 흡입되면서 우물통 내부까지 스며들기 때문에, 이에 따른 우물통의 경도 및 강도가 크게 저하되는 단점과 함께, 시일 경과시 상기 우물통의 저하된 경도 및 강도에 의해 파손이 발생될 수 있는 커다란 단점이 있다.Due to this, in order to solve the above problems, as shown in Figures 3, 3A and 4, a shock absorber for the bridge of the Utility Model Registration No. (Registration No. 20-149829) has been proposed, the configuration thereof Looking at, the reinforcing steel plate (3) having a curved portion (2), such as the curve of the piers on the back surface of the impact modifier (1), and having an anchor hole (3 ') on both sides of the impact modifier (1) Extruded to be inserted in the longitudinal direction of the, the perforations of the plurality of anchor holes (4) on both sides of the front of the shock absorber (1) and the center of the shock absorber (1) formed in the longitudinal direction on the front ( 5) a paint part 6 for painting a luminous material is formed, and the anchor bolt 10 is formed by anchor holes formed on both sides of the shock absorber in a state in which the curved portion of the shock absorber is in contact with a pier or a well. By fixing and attaching Since the shock absorber absorbs the impact of the ship, it has the advantage of protecting the pier or the well while preventing the damage of the ship as much as possible. However, when the water level is low, the impact buffer is fastened to the well supporting the bridge with anchor bolts. And, if the water level is high, the impact buffer is installed up to the height of the pier, there is a problem that a lot of waste of the impact buffer is generated, and as installed above in each well and pier by the difference in the water level, installed in the well When the impact buffer is separated and installed in the piers, assembling and detaching work is very cumbersome, anchor bolt tableting seats are formed at the position where the impact buffer is separated, and water is sucked into the tableting seat to the inside of the well. Due to the permeation, the hardness and strength of the well can be greatly reduced, and thus the well of the well can be reduced. There are also significant disadvantages that may be caused by damage and strength.

더욱이, 물의 수위가 낮아져 교각에 설치된 충격완화재를 분리하여 다시 수위에 맞게 우물통에 설치할 경우 역시, 교각에 형성된 앵커볼트의 타정자리에 의해 교각의 경도 및 강도가 저하되는 문제점 있으며, 상기 타정자리가 그대로 교각에 남아 있기 때문에, 미관상 보기 좋지 않은 커다란 문제점이 있다.Furthermore, when the water level is lowered and the impact buffer installed in the pier is separated and installed in the well according to the water level again, the hardness and strength of the pier are deteriorated by the tableting position of the anchor bolt formed in the pier. There is a big problem that looks aesthetically unsightly since it remains in the piers.

상기와 같은 종래의 제반 문제점을 해결하기 위해 안출된 본 고안은, 강물의 수위변화에 따라 충격완화재를 교각이나 우물통에 상호 이동 설치하기가 자유로우면서, 상기 충격완화재를 분리하여도 상기 교각 및 우물통이 원상태로 유지되어 미관을 해치지 않도록 하며, 교량의 교각사이로 선박 항해시 교각 또는 우물통과의 충돌에 따른 선박 및 교각, 우물통을 보호하면서, 상기 선박에 탑승한 승객들의 인명피해를 방지하도록 하는데 그 목적이 있다.The present invention devised to solve the conventional problems as described above, while the impact buffer is free to install mutual movement in the piers or wells in accordance with the change in the water level of the river, even if the impact buffer is separated And the wells are kept intact so as not to damage the aesthetics, while protecting the vessels, bridges, and wells due to collision with the bridges or wells when navigating the ships between the bridges of the bridges, and prevents the casualties of the passengers on board the vessels. The purpose is to make it.

이러한 본 고안의 목적을 달성하기 위하여, 중앙에 만곡부가 형성되고, 전면양측에 앵커장공이 형성되며, 전면길이방향으로 형성된 홈에 야광물질이 도색된 충격완화재를 앵커볼트에 의해 교각이나 우물통에 타설하도록 구성된 교량용 충격 완화재에 있어서;In order to achieve the object of the present invention, the bent portion is formed in the center, the anchor hole is formed on both sides of the front, the impact relief material painted with luminous material in the groove formed in the front length direction by the pier or pier What is claimed is: 1.
