[Detailed Description of the Invention] This invention relates to the improvement of rubber fenders that are attached to harbor quay walls and the like to protect ships coming alongside.

As shown in FIG. 1, this type of fender has a reinforcing iron plate 2 buried in a mounting seat 1, and anchor bolts 4 buried in a quay wall 3 are inserted into bolt holes formed in the mounting seat 1. It is attached to the quay by inserting it into the pier and tightening the nut 6 through the washer 5.

The anchor bolts 4, washers 5, and nuts 6 are galvanized and have a certain degree of rust prevention effect against seawater, etc., but they do not protect against the reinforcing iron plate 2 buried in the mounting seat 1 of the fender. Conventionally, rust prevention treatment has not been applied. Therefore, the occurrence of rust on anchor bolts and washers is caused by the fact that the rubber layer on the bolt hole wall of the steel plate 2 embedded in the mounting seat 1 of the fender is very thin and the steel plate 2 is easily exposed. , Rust occurs on the embedded iron plate 2, and rust also occurs on the bolts and washers.

また、埋め込み鉄板2のサビ発生は防舷材の寿
命を非常に短いものにする。
In addition, the occurrence of rust on the embedded iron plate 2 significantly shortens the life of the fender.

In view of the above points, this idea was developed by applying sealant (rust-preventing paint) inside the bolt holes of the mounting seat.
The present invention provides a rust-proof structure for rubber fenders fitted with metal rings that have a greater tendency to ionize than iron plates.

C a (calcium) and N a (sodium) cannot be used alone because they react violently with water and must be made into a stable alloy such as amalgam. Furthermore, U (uranium) and Z r (zirconium) are expensive, and M g (magnesium) has the disadvantage of being brittle, so in practice, A l (aluminum), Z o (zinc), or their mutual or M g Preferably, it is alloyed with

FIG. 2 is a perspective view of the fender according to the present invention, where 1 indicates a mounting seat and 7 indicates a bolt hole. A metal ring 9, which has a greater tendency to ionize than the iron plate 2, is fitted and attached thereto. This metal ring 9 is a thin cylindrical ring with a thickness of 1.0 to 1.5 m/m.

With the above structure, when this is installed on a quay wall as shown in Figure 1, a current flows from the metal ring 9 to the anchor bolt, washer, and nut, and this direction is opposite to the direction of the corrosion current in the iron plate 2. ,
Corrosion of the iron plate 2 is prevented for a long period of time until the metal ring 9 is worn out, and corrosion of the anchor bolt, washer, and nut is also prevented, and the life of the fender can be improved.

As explained above, this idea involves applying a sealant to the bolt holes of the mounting seat for rubber fenders in which reinforcing iron plates are buried in the mounting seats for quay walls, etc. Since the rings are fitted and installed, rusting and corrosion of the iron plate can be prevented for a long period of time, and the life of the fender can be improved.Moreover, it has the advantage of being very easy to implement.
