Definitions

  • the present invention relates in general to an anti-corrosion cap for bolts, and more particularly, to an anti-corrosion cap for bolts, which is insert fitted into bolts used for securing outdoor constructions such as bridges to protect the bolts against corrosion so that the constructions may not collapse or damaged.
  • bolts are widely used to fasten or secure bridges or outdoor constructions.
  • the bolts are easily corroded often by rain and wind.
  • bolts which are used for securing bridges are more exposed to corrosion than bolts which are used for securing other kinds of constructions. Once bolts had corroded, they are easily removed from constructions and the constructions secured or supported by the bolts will inevitably collapse.
  • the present invention is conceived to solve the aforementioned problems in the prior art.
  • An object of the present invention is to provide an anti-corrosion cap for bolts, which is insert fitted into bolts used for securing outdoor constructions such as bridges to protect the bolts against corrosion.
  • Another object of the present invention is to provide an anti-corrosion cap for bolts excellent in corrosion protection over bolts, such that constructions secured by those bolts with caps may not collapse or damaged and have increased life span.
  • anti-corrosion cap for bolts comprises a semicircular "n" shaped body which is made of flexible material containing luminous paint; a corrugated tube which is disposed at a lower side of the body and has a variable height depending on the height of a bolt the cap is fitted into; a fixing member which is disposed underneath the body; and a rust preventive oil housing which accommodates rust preventive oil.
  • the fixing member of the anti-corrosion cap for bolts is for fixing the cap to a construction. It has, on its top, a groove to be inserted into the bottom of the body, and a magnet is insert fitted into its bottom to make it bond to the construction.

  • the rust preventive oil housing of the anti-corrosion cap for bolts is disposed inside of an excess metal portion where the screw portion is formed and stores rust preventive oil therein.
  • the cap is fastened into the bolt, its film bursts open and the rust preventive oil being kept inside is put in the bolt.
  • a luminous or photo-luminescent band is coated over the outer surface of the body for an anti-corrosion cap for bolts, or extrusion-molded with the body as one unit.
  • the anti-corrosion cap for bolts of the present invention is insert fitted into bolts used for securing outdoor constructions such as bridges to protect the bolts against corrosion.

Abstract

La présente invention porte sur un capuchon anticorrosion pour boulons, qui est introduit de manière ajustée sur des boulons utilisés pour fixer des constructions extérieures telles que des ponts, pour protéger les boulons contre la corrosion de telle sorte que les constructions ne puissent pas s'écrouler ou être endommagées. Selon un aspect, le capuchon anticorrosion pour boulons comprend un corps en forme de « ∩ » semi-circulaire qui est réalisé en un matériau souple contenant une peinture lumineuse ; un tube ondulé qui est disposé à un côté inférieur du corps et qui a une hauteur variable dépendant de la hauteur d'un boulon sur lequel est ajusté le capuchon ; un élément de fixation qui est disposé au-dessous du corps ; et un logement d'huile antirouille qui reçoit de l'huile antirouille. L'élément de fixation du capuchon anticorrosion pour boulons est destiné à fixer le capuchon sur une construction et possède, sur sa partie supérieure, une rainure devant être insérée dans la partie inférieure du corps, et un aimant qui est inséré de manière ajustée dans sa partie inférieure pour le lier à la construction. Le logement d'huile antirouille du capuchon anticorrosion pour boulons est disposé à l'intérieur d'une partie métallique en excès dans laquelle la partie de vis est formée et stocke de l'huile antirouille dans celle-ci, et lorsque le capuchon est fixé dans le boulon, un film s'ouvre en éclatant et l'huile antirouille qui était maintenue à l'intérieur est poussée dans le boulon. Selon un autre aspect, un capuchon anticorrosion pour boulons comprend un corps en forme de « ∩ » semi-circulaire qui est réalisé en un matériau souple contenant une peinture lumineuse et possède une pluralité de saillies à la partie inférieure ; un tube ondulé qui est disposé à un côté inférieur du corps et a une hauteur variable dépendant de la hauteur d'un boulon sur lequel le capuchon est ajusté ; une partie de vis qui est disposée à l'intérieur du corps devant être fixé dans le boulon ; et un logement d'huile antirouille qui est disposé à l'intérieur du corps et reçoit de l'huile antirouille.
