Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to
The other end is attached to the back surface of the receiving plate, and is provided for use. The plate-like fender supporting member absorbs the shore impact acting on the receiving plate by its own elastic deformation. In particular, it is a small and lightweight supporting member, which always exerts a stable shock absorbing function regardless of the direction of action of a landing impact.

(Prior Art) As a conventionally known supporting member for fenders, for example, there is a member disclosed in Japanese Utility Model Publication No. 56-9707,
As shown in the sectional view of FIG. 1, on the lower surface of the receiving plate member 1, a receiving portion 2, a mounting portion 3 parallel thereto, and the receiving portion 2 inclined with respect to the receiving portion 2 and the mounting portion 3. Collision part 2 and mounting part 3
In a fender in which at least a pair of rubber supporting members including a supporting portion 4 for connecting the rubber supporting members are detachably mounted symmetrically so as to spread downward, the rubber supporting members receive the rubber supporting members. Part 2 inward from the inner surface of its support 4
The mounting portion 3 is configured to protrude outward from the outer surface of the support portion 4 like a flange.

When such a supporting member acts on a shore load in a direction perpendicular to the receiving plate member 1, as shown in FIG. It can be effectively relaxed.

(Problems to be Solved by the Invention) However, in such a conventional fender support member, since the mounting portion 3 protrudes considerably outward from the outer surface of the support portion 4, the mounting member 3 cannot be used. However, the mounting area to the berthing facility becomes large, and therefore, there is a problem in the structure cost that the surface area of the berthing facility must be increased,
In addition, a bolt head for attaching the mounting portion 3 and the receiving portion 2 which projects considerably inward from the inner surface of the support portion 4 to the berthing facility and the receiving plate member 1 and the like project outside. As a result, there is a problem in the handling of the rope that a rope or the like is hooked there. Furthermore, metal reinforcing plates 5 and 6 buried from the receiving part 2 and the mounting part 3 to the supporting part 4, respectively. Due to the large size of the support member, there is a problem that the weight and volume of the support member are increased and the cost is also increased.

In addition, this conventional fender support member is designed to provide an S-shaped elastic deformation as shown in FIG. Such a configuration is also possible in that a portion adjacent to the receiving portion 2 is provided with an upper end portion which is oriented at right angles to the upper portion, and an inner surface of the portion adjacent to the mounting portion 3 is provided with a bent-shaped surface. In some cases, as is the case with most of the side impacts acting on the fender support members, if it acts obliquely with respect to the plate surface, the S It is almost impossible to always achieve a bending deformation in the shape of a letter, and in fact, the support member will exhibit different deformation behavior for each impact at the side of the ship. There is a problem that the shock absorption performance fluctuates greatly.

The present invention provides a fender support member that can solve all of the problems of the prior art.

(Means for Solving the Problems) The present invention has one end attached to the surface of the berthing facility and the other end attached to the surface of the receiving plate, and is inclined with respect to both surfaces that are substantially parallel to each other. In a substantially plate-shaped fender supporting member located, a mounting portion of the supporting member to a berthing facility is a surface of an end portion of the colliding member adjacent to the berthing facility facing a receiving plate. While being formed in the recess provided from the side, the mounting portion to the receiving plate is formed in the recess provided from the surface side facing the berthing facility of the end portion of the supporting member adjacent to the receiving plate,
Furthermore, the curved surface which is located in the vicinity of the berthing facility and the vicinity of the receiving plate, respectively, on the surface facing the berthing facility and the surface facing the receiving plate of the supporting member, and is depressed in the direction of reducing the thickness A depression is provided.

(Operation) In this fender support member, each mounting portion provided at both ends thereof is connected to a reinforcing plate made of a rigid material which is embedded from each of the mounting portions to the supporting member body portion. If a collision impact is applied to the receiving plate under the condition that it is bolted to each of the berthing facilities and the receiving plate, the impact is applied to the S-shaped elastic deformation of the supporting member. Can very effectively buffer.

Here, the bolting of the support member as described above is performed by mounting portions formed in the respective recesses at both end portions thereof, and those mounting portions are not attached to any surface side of the support member. Since it does not protrude, the mounting area of the supporting members, especially to the berthing facilities, can be significantly reduced as compared with the prior art, and therefore, the mounting area of the fenders of the berthing facilities and, consequently, the The construction cost will be sufficiently reduced.

According to the above-described mounting portion, the head of the mounting bolt, the screw portion, and the like can be sufficiently accommodated in the recess, and the dimension of the reinforcing plate embedded in the mounting portion can be sufficiently reduced. The troublesome handling of the cable can be almost completely eliminated.
Cost reduction can be realized.

In addition, here, the curved surface recessed portions provided at each of the end portion on the side of the berthing facility and the end portion on the side of the receiving plate of the supporting member function as extremely effective deformation guiding portions. In any case, the deformation of the support member can be made substantially constant irrespective of the action direction, and therefore, a stable shock absorbing function can be always exerted.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view showing an application example of the present invention, in which 11 is a quay as an example of a berthing facility, 12 is a receiving plate, and 13 is a substantially plate-like overall. None, the figure shows a fender support member extending in the vertical direction of the quay 11.

In this example, one end of each of a pair of supporting members 13 mainly composed of rubber or a rubber-like elastic material is provided on the front surface 11a of the quay wall 11, and the other end is provided on the back surface 12a of the receiving plate 12. Each of the support members 13 is attached by bolts and nuts so that each of the support members 13 is inclined with respect to their surfaces 11a and 12a which are substantially parallel to each other. The relative attitude shall be gradually expanded toward the quay side.

Also, here, each support member 13 has an attachment portion 14 to the quay 11.
Is formed in a depression 15 provided from the surface side of the supporting member 13 adjacent to the quay 11 facing the receiving plate 12, and a mounting portion 16 to the receiving plate 12 is formed by: An end of the support member 13 adjacent to the receiving plate 12 is formed in a recess 17 provided from the front side facing the quay 11.

The cross-sectional contours of the depressions 15 and 17 here correspond to the tightening surfaces of the mounting portions 14 and 16 by the quay surface 11a.
As long as it can be formed in parallel with the back surface 12a of the receiving plate, various changes can be made as required.

Here, in such a support member 13, reinforcing plates 18, 19 made of a rigid material that reach from the mounting portions 14, 16 to the main body portion 13 a of the support member 13 in the respective mounting portions 14, 16. Are buried in parallel with the quay surface 11a and the back surface 12a of the impact plate, thereby ensuring the load supporting capacity of the mounting portions 14, 16.

Further, in this example, on the surface 13b facing the quay side and the surface 13c facing the receiving plate side of the supporting member 13, the supporting member 13 is located near the quay 11 and the receiving plate 12, respectively. Curved surface depressions 20 and 21 are provided which are depressed in a direction to reduce the thickness of the collision member itself.

According to the illustrated fender using the above-described support members 13, each of the support members against the fender impact acting on the receiving plate 12 from a direction perpendicular thereto is provided. 13
Under the action of the curved surface depressions 19, 20 provided at appropriate positions on the respective surfaces 13b, 13c, as shown in FIG. 1 (b), they are always elastically deformed in a substantially S-shape. Due to the elastic deformation, the impact at the side is sufficiently buffered and effective absorption of the impact energy is performed.

This is substantially the same also when the landing impact acts obliquely on the surface of the receiving plate 2, and in such a case, the respective supporting members 3 are also shown in FIG. As shown in the figure, under the extremely excellent deformation inducing action of the curved surface depressions 19 and 20, it is always elastically deformed into a substantially S-shaped shape, and therefore, it has a sufficiently stable shock absorbing function. Can be.

In addition, in this support member 13, any of the mounting portions 14, 1
6 will also be included inside the extension of each surface 13b, 13c, so that mounting bolts, tightening nuts, etc. will be completely accommodated in the respective recesses 15, 17 of the support member 13. Therefore, it is possible to effectively prevent ropes and other stowage from being caught and accommodated, making it extremely easy to handle the ropes, and at the same time, to occupy a sufficient area of the mounting portion 14 on the quay surface 11a. By reducing the size, it is possible to reduce the cost of quay construction. In addition, here, since the size of each of the reinforcing plates 18 and 19 embedded in the mounting portions 14 and 16 is reduced, the size and weight and cost of the support member 13 are achieved.

In the above-described embodiment, when the surface 13b facing the quay side and the surface facing the receiving plate side of the support member 13 extend in parallel to each other, the quay 11 And, when the mounting portion to the receiving plate 12 is protruded somewhat inward and outward from the respective surfaces 13b and 13c described above, the support member 13 can be reasonably elastically deformed, It can have excellent durability even after repeated large deformation.

Here, the distance between the quay surface 11a and the back surface 12a of the impact plate is H
And was the time, the quay surface 11a, the curved recess 30 of the distance h ₁ of the tip to the edge and 0.2~0.25H, 0.25~0.3H the distance h ₂ from the impact receiving plate back surface 12a to a rear edge of the curved recess 21 In this case, there is an advantage that the elastic deformation of the support member 13 can be made particularly stable.In general, the inclination angle θ of the support member 13 with respect to the quay surface 11a is set to 70 to 72 °. But,
This is preferable for generating a large restoring reaction force of the support member 13 and stabilizing elastic deformation.

The inclination angle θ can be appropriately selected in relation to the thickness of the support member 13.

From an economic point of view, the supporting member 13
Thickness t in the direction perpendicular to the distance H is 0.25 to 0.28
H is preferred.

FIG. 3 is a view showing another application example of the present invention. In this example, one supporting member 13 which faces in the horizontal direction with respect to the quay surface 11a is formed as an inclined posture in which the tip portion faces downward. Quay
The receiving plate 12 is attached to each of the receiving plates 12, and the lower end of the receiving plate 12 is embedded in the water bottom 22, for example, in the form of a column.

In such fenders, when a shore impact P acts on the receiving plate 12, the receiving plate 12 is subjected to impact under its own elastic deformation with its embedded portion in the water bottom 22 as a fulcrum. By swinging in the direction of action of P, the support member 13 is elastically deformed in the same manner as in the above-described example. And effective absorption of the collision energy.

Since the support member 13 here also has the same configuration as that of the above-described example, it is possible to sufficiently exhibit the specific operation and effect derived from the configuration.

Although the present invention has been described based on the illustrated example, it is also possible to attach each of the two supporting members to the berthing facility and the receiving plate in a posture of expanding toward the receiving plate side. Further, it is also possible to attach one supporting member to each of the berthing facility and the embedded receiving plate in an inclined posture in which the tip end faces upward.

(Effects of the Invention) Thus, according to the present invention, in particular, the respective mounting portions provided at both ends of the support member are located inside the extended surfaces of the respective surfaces of the support member, thereby supporting the support member. The mounting area of the collision member to the berthing facility can be significantly reduced, and the size of the reinforcing plate embedded in each mounting portion can also be significantly reduced. It is possible to almost completely eliminate the catching of the rope on the bolts and nuts fixed to the port facilities and the receiving plate, the clinging, and the like.

In addition, here, based on the excellent deformation inducing action of the curved surface dents provided in the vicinity of the berthing facility and the receiving plate, the deformation mode of the supporting member regardless of the direction of the shore impact is described. As a result, the shock absorbing function can be exhibited at all times, and the durability can be sufficiently improved.
