本発明はゴム製防舷材の製造方法に関し、特
に、補強用鉄板の開口への露出を防止することが
できる内部に補強鉄板を埋設されたゴム製防舷材
の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a rubber fender, and in particular to a method for manufacturing a rubber fender, in which a reinforcing iron plate is embedded inside which can prevent the reinforcing iron plate from being exposed to an opening. This relates to a manufacturing method.
船舶を接岸する際に、船舶の接岸エネルギーを
吸収し船体の損傷を防ぐために防舷材が使用され
る。この防舷材はそのフランジ部を岸壁面に螺子
式取付け具で固定することによつて取り付けられ
るのが一般的である。 When a ship berths, fenders are used to absorb the berthing energy of the ship and prevent damage to the ship's hull. This fender is generally attached by fixing its flange portion to the quay surface with a screw type attachment.
そして防舷材のフランジ部および受衝部には、
これらの箇所を補強するために鉄板が埋設され
る。防舷材を製造するに際して、これらの補強用
鉄板は予め金型内所定位置に配置され、この後で
ゴムが金型内へ仕込まれる。このとき金型内に配
置された補強用鉄板の位置がずれ、金型から防舷
材を取出したとき、防舷材の開口部に補強用鉄板
が露出することとなる。 In the flange part and impact receiving part of the fender,
Steel plates will be buried to reinforce these points. When manufacturing fenders, these reinforcing iron plates are placed in advance at predetermined positions in a mold, and then rubber is charged into the mold. At this time, the position of the reinforcing iron plate placed in the mold shifts, and when the fender is removed from the mold, the reinforcing iron plate is exposed at the opening of the fender.
このように補強用鉄板が開口部に露出した防舷
材を使用すると、露出部が腐蝕し、これが鉄板全
面に進行してゴムがやがて剥離しゴム本体が欠落
する危険性があり、又防舷材の取付け具の挿通を
妨げることとなり、商品価値は極めて低くなつて
しまう。 If you use a fender with reinforcing iron plates exposed in the openings, there is a risk that the exposed parts will corrode, and this will progress to the entire surface of the iron plate, causing the rubber to peel off and the rubber body to be missing. This will impede the insertion of the fixture into the material, and the commercial value will be extremely low.
それ故本発明の目的は、補強用鉄板の開口への
露出を防止することができる内部に補強鉄板を埋
設されたゴム製防舷材の製造方法を提供すること
にある。 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method of manufacturing a rubber fender in which a reinforcing iron plate is embedded, which can prevent the reinforcing iron plate from being exposed to the opening.

れたゴム製防舷材の製造方法が提供される。 According to the present invention, a step of arranging a spacer member around a mold part for forming an opening in a rubber fender, a step of arranging a reinforcing steel plate around the spacer member, and a step of placing rubber into the mold. Provided is a method for manufacturing a rubber fender in which a reinforcing iron plate is embedded, the method comprising the step of:
以下添付の図面を参照して本発明の好ましい実
施例について説明する。 Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

線に直交する面に沿つて延びて一体的に形成され
た環状フランジ３から成る。 FIG. 1 is a sectional view of an example of a conventionally well-known fender. The fender shown in Fig. 1 includes a hollow truncated conical bearing part 1 and an integrally formed cylindrical bearing part extending from the small diameter end of the bearing part 1 in a direction parallel to the axis. It consists of an abutment part 2 and an annular flange 3 which is integrally formed and extends from the large diameter end of the support part 1 along a plane perpendicular to the axis.
環状フランジ３はその内部に補強鉄板５を埋設

設する際、取付基板としての役目をなす。 The annular flange 3 has a reinforcing iron plate 5 embedded therein. Further, a reinforcing iron plate 5 is buried inside the top surface of the impact receiving portion 2 as necessary. This reinforcing iron plate 5 provides rigidity to the top surface of the impact receiving part 2, and also
When attaching a larger-area impact-receiving plate material on the top surface of the impact-receiving part 2, it serves as a mounting board.

む。 FIG. 2 shows a mold part 4 corresponding to the opening of the fender, and according to the method of the present invention, a plurality of spacer members 6 are first arranged around the mold part 4. Preferably, this spacer member 6 is constructed from semi-vulcanized rubber, a strip or a rubber chip. Next, a reinforcing iron plate 5 is placed around the spacer member 6,
A constant distance is maintained between the iron plate 5 and the mold part 4 corresponding to the opening. After that, the rubber is put into the mold.

全に防止される。 FIG. 3 shows a cross section of the opening of a fender manufactured by the method of the present invention comprising such steps. Third
As can be easily understood from the figure, by arranging the spacer member 6 in advance in the mold, the reinforcing iron plate 5 is completely prevented from shifting during vulcanization and being exposed into the opening.
