従来より使用される、受衝部と、岸壁に向つて
受衝部よりのびる支衝部と、岸壁側に於て支衝部

下する場合が多い。 Conventionally used defenses have a hollow structure consisting of an impact receiving part, a supporting part extending from the impact receiving part toward the quay, and a base provided integrally with the supporting part on the quay side. Regarding fenders, when ships come alongside, the direction of the force that the impact receiving part of the fender receives is not only in the right angle direction (normal compression), but also in the diagonal direction (slanted compression) in many cases. When subjected to such inclined compression, forced deformation occurs in the support portion, and compression performance often deteriorates accordingly.
本発明は上記の如き欠点を排除した傾斜接舷に
も適した防舷材を提供するものであり、その要旨
とするところは、受衝部と、岸壁に向つて受衝部

の傾斜接舷用防舷材に存する。 The present invention provides a fender which eliminates the above-mentioned drawbacks and is suitable for sloping berths. In a fender having a hollow chamber formed by an abutment and a base integrally provided with the abutment on the quay side, a Y-shape is formed in the hollow chamber toward the impact receiving section. The present invention relates to a fender for inclined berths having a structure in which a reinforcing portion is integrally provided.
以下に添附図面により本発明を具体的に詳述す
る。 The present invention will be specifically explained in detail below with reference to the accompanying drawings.

向つてＹ字形乃至三ツ又状をなす補強部ｅが一体
的に設けられている。基部ｃには通常補強用鉄筋
又は鉄板等の補強材ｆが埋設されている。 FIG. 1 is a cross-sectional view of the fender for inclined berthing according to the present invention, in which a is the impact receiving part, b is the supporting part, and c is the base on the quay side. As shown in the figure, a Y-shaped or trifurcated reinforcing portion e is integrally provided in a hollow chamber d surrounded by a base portion c, facing toward the impact-receiving portion a. A reinforcing material f such as a reinforcing reinforcing bar or an iron plate is usually buried in the base c.
なお、補強材ｆとしては高硬度ゴム、金属、樹
脂等が好ましく使用される。 In addition, as the reinforcing material f, high hardness rubber, metal, resin, etc. are preferably used.

10゜）に於ては大巾に圧縮性能が低下することが
明らかである。 The graph in FIG. 2 shows the results of testing the compression performance of the fender according to the present invention and the conventional type fender when a ship comes alongside such a fender. In other words, the direction in which the ship is perpendicular to the impact receiving part (θ = 0° if the angle between the ship's side and the impact receiving part's side plane is θ) and the angle between the ship's side and the impact receiving part's board side plane are 10° (i.e. θ=
The relationship between the reaction force coefficient (coefficient when the reaction force of 45% normal compression is taken as 100) and strain (%) is as shown in the graph for both cases of 10° incline alongside. The fender is inclined to the side (θ=10°)
Even in the case of normal compression (θ=0°), there is almost no difference in compression performance between the conventional product (θ=0°) and the conventional product (θ=0°).
10°), it is clear that the compression performance decreases significantly.
