풀림방지볼트와 풀림방지판이 결합된 볼트풀림방지구조{Loose stopper bolt and plate}Loosening prevention bolt combined with loosening prevention bolt and loosening prevention plate {Loose stopper bolt and plate}

본 발명은 볼트의 풀림방지구조에 관한 것으로서, 보다 상세하게는 풀림방지볼트가 구조물에 체결된 상태에서 볼트의 헤드부 쪽으로 헤드부의 형상과 대응되는 형상의 끼움홈을 가진 풀림방지판을 체결함으로써 구조물의 고정에 사용된 풀림방지볼트가 충격이나 진동에 의해 임의로 풀리는 것을 방지한 풀림방지볼트와 풀림방지판이 결합된 볼트풀림방지구조이다.The present invention relates to an anti-loosening structure of a bolt, and more particularly, by fastening an anti-loosening plate having a fitting groove having a shape corresponding to the shape of the head toward the head of the bolt while the anti-loosening bolt is fastened to the structure. The bolt-locking structure is combined with the bolt-locking bolt and the bolt-locking plate to prevent the bolt-locking bolt used to fix the bolt.

일반적으로 교량이나 H빔을 이용한 건축물과 같은 구조물의 경우 분리되어 있는 두 개의 구조물을 서로 결합하기 위해 두 구조물에 볼트홀을 뚫고 체결판을 덧대어 상기 고정판에 볼트를 체결함으로써 두 구조물을 단단히 고정해주게 된다.In general, in the case of a structure such as a bridge or an H-beam structure, in order to join two separate structures to each other, a bolt hole is formed in the two structures and a fastening plate is applied to fix the two structures firmly. do.

도 1은 종래 구조물의 결합예시를 도시한 도면으로써, 분리되어 좌우로 배치되어 있는 두 개의 구조물을 결합해주기 위해 체결판을 덧대어 다수의 볼트로써 체결판과 구조물을 서로 결합해주는 구조인데, 이러한 구조물이 계속하여 진동을 받는 구조물 즉, 교량과 같은 경우에는 볼트에 진동이 가해져 볼트가 임의로 풀림으로써 구조물의 강성이 저하되고, 심할 경우 붕괴가 발생하게 된다.1 is a view showing a coupling example of a conventional structure, a structure that combines the fastening plate and the structure with a plurality of bolts by attaching a fastening plate to combine the two structures separated and disposed left and right, such a structure In the case of a structure that is continuously vibrated, that is, a bridge, vibration is applied to the bolt, and the bolt is arbitrarily released to lower the rigidity of the structure.

이러한 볼트의 풀림방지와 관련된 종래기술로서는 볼트를 체결판에 고정한 뒤 볼트의 일측에 너트를 결합할 때 상기 볼트와 너트의 나사산 사이에 혐기성 접착제를 뿌려 풀림을 방지하게 되는데, 접착제의 경우 별도의 도포장비가 필요하고 접착제의 특성상 사용기간이 경과하게 되면 접착력이 떨어져 사용기간에 따라 볼트가 임의로 풀릴 수 있다.In the related art related to preventing loosening of the bolt, when the bolt is fixed to the fastening plate and the nut is coupled to one side of the bolt, an anaerobic adhesive is sprayed between the bolt and the thread of the nut to prevent loosening. If equipment is needed and the service life has elapsed due to the nature of the adhesive, the adhesive strength may be reduced and the bolt may be released arbitrarily according to the service life.

또 다른 방법으로서는 이중와셔를 볼트와 너트 사이 혹은, 볼트와 구조물 사이에 끼워 풀림을 방지하게 되는데, 풀림방지력이 떨어지고 이중와셔의 부식으로 인해 오히려 볼트의 부식을 촉진시키는 문제가 발생될 우려가 있으며, 그 비용 또한 상승될 수 있다.As another method, the double washer is inserted between the bolt and the nut, or between the bolt and the structure to prevent loosening. However, the loosening resistance is reduced and the corrosion of the double washer may cause the problem of promoting the corrosion of the bolt. The cost can also be increased.

또 다른 방법으로서는 볼트의 나사산에 수지를 코팅하여 볼트의 풀림과 부식을 동시에 방지하는 방법이 있으나, 이러한 방법은 수지가 직사광선에 노출될 경우 수지의 피막파괴로 인해 부식방지효과가 떨어지고 풀림방지력을 상승시키기에는 부족한 부분이 있었다.Another method is to coat the threads of the bolts with resin to prevent loosening and corrosion of the bolts at the same time.However, when the resin is exposed to direct sunlight, this method reduces the anti-corrosion effect due to the resin's film breakdown and prevents loosening. There was not enough to raise.
