Description

[Detailed Description of the Invention] (Industrial Application Field) This invention provides a method for attaching one end to the surface of a quay or other alongside facility.
The other end is attached to the back side of the impact plate for use, and is a substantially plate-shaped fender support that absorbs the side impact acting on the impact plate by its own elastic deformation. Regarding the member, in particular, it is one that always exhibits a stable shock absorbing function regardless of the direction of action of the alongside impact.

(Prior Art) As a conventional support member for fenders of this kind mainly made of rubber or rubber elastic material, for example,
There is one disclosed in Publication No. 34319.

This consists of a pair of supporting members, each of which is a plate-shaped body whose cross-sectional shape is a parallelogram when cut with a plane that is perpendicular to the bottom surface and faces in the thickness direction. Yes, such supporting members are made of two pieces as a pair.
By attaching their respective bottom surfaces to the surface of the berthing facility and their top surfaces to the back surface of the impact receiving plate, a relative posture in which both of these supporting members are gradually expanded toward the berthing facility. By doing so, a fender can be constructed.

According to such a fender, the action of the impact on the impact plate when coming alongside is effectively absorbed by the substantially S-shaped bending of both support plates.

(Problem to be Solved by the Invention) However, in this prior art, the cross-sectional shape of the support member is a parallelogram, and there is no guiding member for bending the support member into an S-shape. Since there is no such force, apart from the case where the side impact acts in a direction perpendicular to the surface of the impact plate, the component force in the direction along the surface of the impact plate is In this case, it is virtually impossible to always realize the S-shaped bending mode of the support member, and in reality, the support member has a different bending shape for each side impact. This causes a problem in that the shock absorbing performance of the support member varies greatly.

The present invention advantageously solves the problems of the prior art, and provides a fender support member that can always exhibit a stable shock absorbing function regardless of the effects of side impact. It belongs to

(Means for Solving the Problems) The fender supporting member of the present invention is attached to the surface of the alongside facility and the back surface of the impact plate, which are parallel to each other, and forms an inclined attitude with respect to both surfaces. At least one of the surfaces of the support member, the surface facing the berth facility and the surface facing the impact receiving plate, is bent at an intermediate position between the surface of the berthing facility and the back surface of the impact receiving plate in a direction in which it expands outward. It is something that

(Function) In this fender support member, preferably the expansion angle α of the refracting surface is 180°>α≧150°, and each refractive position is set between the surface of the fender and the back of the impact plate. By setting the distance from the mounting surface of the support member to 0.2H to 0.35H with respect to the distance H from The mode of the bending deformation is almost constant regardless of the direction in which the side impact is applied, so that a stable shock absorption function can always be exhibited.

(Example) Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a cross-sectional view showing one embodiment of the present invention, in which 1 represents a quay as an example of a berth facility, 2 represents an impact plate, and 3 represents a plate-like structure as a whole. None, the figure shows a fender support member extending in the vertical direction of the quay l.

Here, one end of each of the supporting members 3, which normally form a pair, is attached to the surface 1a of the quay 1, and the other end is attached to the back surface 2a of the impact plate 2. , their substantially parallel surfaces 11a, 12
Although it is not clear from the figure, each pair of supporting members is positioned at an angle with respect to the quay side, and is in a relative position in which they gradually expand toward the quay side.

In this example, in this bracing member 3, the surface 3a facing the quay l is located at an intermediate position between the quay wall surface 1a and the back surface 2a of the impact plate, preferably at a distance H between the two surfaces 1a+2a. 0.2H to 0.35H from surface 1a
At the position, it is bent toward the quay side in the direction of expansion at an angle α, and preferably the expansion angle α is 180°〉α≧15.
06, and the minimum thickness T at the bending position 4
is set to 0.2H to 0.3H.

Here, the refraction position 4 of the surface 3a is set to 0 from the quay wall surface 1a.
．． 2H to 0.35H, the expansion angle α of the refraction position 4 is set to 180°>α≧150°, and the minimum thickness T at the refraction position 4 is set to 0.2H to 0.35H. The reason why 3H is selected is that the deformed shape of the impact member 3 is always guided into an S-shape regardless of the direction of action of the side impact, so that a stable impact absorption function can be exhibited.

In addition, here, the attachment part 5 of the support member 3 to the quay l is
The support member 3 is formed in a recess 6 provided from the surface side facing the impact plate 2 in a portion adjacent to the quay wall 1, and the attachment portion 7 to the impact plate 2 is attached to the support member 3. Formed in a recess 8 provided from the surface side facing the quay wall 1 in a portion of the member 3 adjacent to the impact receiving plate 2, and each of these mounting portions 5,
7, reinforcing plates 9 and 10 made of a rigid material extending from the attachment parts 5 and 7 to the main body portion 3b of the support member 3 are buried parallel to the quay wall surface 1a and the impact plate surface 2a, respectively. This ensures the load supporting ability of the mounting parts 5 and 7.

Note that the recesses 6 and 8 for forming the respective mounting portions 5 and 7 can also be formed from the surface side opposite to the respective surfaces described above, and the recesses 6 , 8 can be varied as required, as long as the tightening surface of the mounting portion 5.7 can be formed parallel to the quay wall surface 11a and the back surface 12a of the impact plate.

2 and 3 are cross-sectional views showing other embodiments of the present invention, and the embodiment shown in FIG.
The surface 3c facing the impact plate 2 is the same as the surface 3a of the embodiment described above.
As in the case of 0.0, preferably from the back surface 2a of the impact receiving plate.
At position 11 between 2H and 0.35H, it is bent in the direction of expanding at an angle α toward the impact receiving plate, and preferably, the expansion angle α is 180′ >α≧150°, and the bending position The minimum wall thickness T@0.2HN3.3H in No. 11 is used.

The example shown in FIG. 3 is a combination of the example shown in FIG. 1 and the example shown in FIG. Each of the surfaces 3c facing the direction is bent in the same manner as in each of the above-mentioned examples.

As shown in FIG. 4, each of the supporting members 3 configured as described above has the thinnest thickness when a side impact in a direction perpendicular to the surface of the impact receiving plate 2 is applied to the impact receiving plate 2. Because it is elastically deformed based on the induction of bending deformation at the bending position, and always exhibits an S-shaped deformation pattern, it can exhibit an extremely stable shock absorption function against side impact.

This is almost the same when the side impact has a force component in the direction along the surface of the impact receiving plate 2, and in such a case, each supporting member 3 is As shown in Fig. 5, under the deformation-inducing effect of the bending position, it is always elastically deformed into an almost S-shape, and as a result,
It can exhibit a sufficiently stable shock absorption function.

(Effects of the Invention) Thus, according to the present invention, by bending at least one of the surface of the support member facing the alongside facility and the surface facing the impact receiving facility in the direction of expanding outward. , regardless of the direction of action of the side impact, the deformation of the support member can be made almost constant; therefore,
It is possible to always exhibit a stable shock absorption function, and at the same time, it is possible to effectively improve durability.
