[Prior art]
As is well known, it is indispensable to install a fender for buffering shocks when a ship collides with a revetment structure for bringing a ship into contact with the berth, or a revetment structure with which there is a risk of contact or collision with the ship. is there. The fender is generally made of rubber having an impact energy absorbing effect, and is usually attached directly to the revetment structure, but if the target ship is large A large number of fenders are required, and naturally the revetment structure to which the fenders are attached is required to have a strength that can withstand the impact force.

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment when the fender according to the present invention is applied to a large-scale simulated waterway provided as a play facility in a theme park will be described. FIG. 1 is a plan view showing a part of the simulated water channel 1, wherein reference numeral 2 is a concrete wall body as an original revetment structure, 3 is provided on the front side thereof, and the revetment structure 2 is disposed on the back side. This is a simulated revetment structure concealed in The simulated revetment structure 3 is formed, for example, in a state imitating a natural rock by a resin molded plate.
[0010]
A simulated ship 4 that is substantially the same as an actual ship sails in the simulated waterway 1, and there is a concern that the simulated ship 4 may come into contact with or collide with the simulated revetment structure 3 and the original revetment structure 2. Therefore, the revetment structure 2 is provided with a large number of fenders 5 according to this embodiment in order to buffer the impact when the simulated ship 4 comes into contact.
[0011]
As shown in FIG. 2, the fender 5 according to the present embodiment includes a main fender 6 attached to the revetment structure 2, and a simulated ship 4 directly in front of the main fender 6. The auxiliary fenders 7 installed so as to be in contact with the main fenders, the main fenders 6 and the auxiliary fenders 7 are connected, and the impact force when the simulated ship 4 comes into contact with the auxiliary fenders 7 is measured. It is comprised with the flame | frame 8 which is transmitted from the auxiliary fender 7 to the main fender 6.
[0012]
The main fender 6 is a rubber hollow rod fixed horizontally to the surface of the revetment structure 2 or the frame 8 and is a general-purpose one used as a conventional fender. For example, the cross-sectional dimension is about 250 mm × 250 mm and the length is about 1.2 to 1.4 m.
[0013]
The frame 8 includes a horizontal truss 9 having a triangular shape in plan view and three support columns 10 that support the truss. The horizontal truss 9 includes a main material 11 made of H-shaped steel fixed to the front side of the main fender 6 and a base end portion connected to both end portions of the main material 11 and extending forward to each other. It consists of the lattice material 12 which consists of one to two steel pipes connected to each other. The support column 10 is made of a steel pipe, and is erected on a concrete bottom board 13 constituting a water bottom surface via a foundation block 14, and the position of each vertex of the horizontal truss 9, that is, both ends of the main material 11 Each of the connecting portions of the lattice material 12 is supported. Reference numeral 15 denotes a brace provided between the supports 10 as necessary. In addition, as a material of the horizontal truss 9 and the support | pillar 10, it is preferable to employ | adopt a stainless steel material, a hot-dip galvanized steel material, etc. in consideration of corrosion resistance, However, If maintenance is possible, it can also be made into a wooden.
[0014]
The auxiliary fender 7 is a dummy that is supposed to contact and collide with the simulated ship 4 but does not have a fender function by itself, and supports the tip of the horizontal truss 9. It is arranged vertically along the column 10, its upper end is fixed to the tip of the two lattice members 12, and its lower end is connected to the lower part of the column 10. The auxiliary fender 7 has a design that fits into the simulated water channel 1 without a sense of incongruity. For example, a pseudo-tree simulating a log that is driven into the bottom of the water and protrudes onto the water surface can be suitably used. In addition, it is preferable that the surface of the auxiliary fender 7 is subjected to a treatment so as to obtain a buffering effect that does not damage the simulated ship 4 when it comes into contact. It is necessary to have a strength that does not easily cause damage when they come into contact with each other. Natural log material may be used as it is if possible.
[0015]
As shown in FIG. 1, the fender 5 according to the present embodiment has only the sub-fender 7 exposed to the front of the simulated revetment structure 3, and is composed of other members, that is, a horizontal truss 9 and a column 10. The entire frame 8 and the main fender 6 are arranged along the revetment structure 2 in a state of being concealed together with the original revetment structure 2 on the back side of the simulated revetment structure 3. Therefore, the fender 5 appears as if logs are standing in a row in front of the natural rocks from the simulated ship 4 navigating the simulated waterway 1. It blends in with no sense of incongruity.
[0016]
As described above, the fender 5 of the present embodiment can be installed in a play facility such as the simulated waterway 1 without a sense of incongruity, and when the simulated vessel 4 contacts or collides with the auxiliary fender 7 The impact force is transmitted to the main fender 6 through the horizontal truss 9, and the main fender 6 can provide a fender effect without any trouble. Moreover, in this case, the impact force is dispersed from the auxiliary fender 7 by the one-to-two lattice material 12 and transmitted to the main material 11, and is transmitted from the main material 11 over the entire length of the main fender 6. Therefore, the total length of the main fender 6 contributes to buffering, and the fender effect is enhanced rather than the case of the conventional general fender that concentrates the impact at only one point of collision. Of course, the main fender 6 is directly attached not to the simulated revetment structure 3 but to the concrete frame that is the original revetment structure 2 concealed behind it, so when the simulated ship 4 collides The impact force can be reliably received by the original revetment structure 2, and the simulated revetment structure 3 has no fear of contact with the simulated ship 4, so that it does not require any strength against the protection, so the simulated revetment structure 3 is simply a dummy.
[0017]
FIG. 3 shows a fender 20 according to another embodiment. This is because one front column 10 supporting the front end of the horizontal truss 9 is also used as the auxiliary fender 7 as it is, and the two columns 10 on the rear side supporting the main member 11 are three-way frames. In contrast to the above-described embodiment, it is possible to use a simple building frame material in the form of a frame and to be able to be tilted to the revetment structure 2 side by pin-bonding each support column 10 to the bottom plate 13 with a pin 21. Although the structure is simplified as a whole, the same effect can be obtained. In particular, since the lower end portion of the column 10 is pin-joined, when the simulated ship 4 comes into contact with or collides with the auxiliary fender 7 that also serves as the column 10, each column 10 naturally falls to the main fender 6 side. By rotating and displacing the horizontal truss 9, there is an effect that the impact force can be transmitted to the main fender without fail and without any unreasonable bending force or moment being applied to each column 10.
[0018]
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and appropriate design changes as listed below are possible depending on the installation location and application. .
[0019]
In the above embodiment, the horizontal truss 9 is adopted as the frame 8 for transmitting the impact force. However, as long as the impact force can be reliably transmitted from the auxiliary fender 7 to the main fender 6, the frame is used. 8 is not limited to the horizontal truss 9, and any configuration can be adopted. Further, even when the horizontal truss 9 is adopted, it is not limited to a simple triangular shape composed of one to two lattice materials 12 and one main material 11 as in the above embodiment, It is conceivable to adopt a truss having a normal shape that is long in the lateral direction with a large number of lattice materials in between. Of course, it is possible to connect a large number of the fenders 5 and 20 of the above embodiment in the horizontal direction to make the fenders long in the horizontal direction, or, as shown in FIG. For example, a cross member 16 that is similar to a log material or a natural log material may be passed between the fenders 7 so that the simulated ship 4 can come into contact therewith.
[0020]
In the above embodiment, the horizontal truss 9 is supported by the support column 10. However, the support column 10 may be omitted if the frame 8 can be supported in a cantilever state from the main fender 6 and there is no problem in transmitting the impact force. It is possible to provide the entire frame 8 under the water surface in a submerged state.
[0021]
Since the said embodiment is an example at the time of applying to the simulated waterway 1 in an amusement facility, it assumed that it was concealed by the simulated revetment structure 3 except the auxiliary fender 7, but the form and structure of the simulated revetment structure 3, The material is arbitrary, and of course the simulated revetment structure 3 may be omitted if there is no need for concealment.
[0022]
Furthermore, when it is not preferable to provide the fender in an exposed state as usual, the present invention is practically applicable to the simulated waterway 1 in a play facility where the simulated ship 4 navigates as in the above embodiment. Although it is optimal, it is not limited to that, and it does not prevent installation of actual ships in actual waterways and ports.
[0023]
【The invention's effect】
The fender according to the first aspect of the present invention includes a main fender attached to the revetment structure, and a sub fender installed at a position in front of the main fender so that the ship can be in direct contact with the fender. And a frame that is interposed between the main fenders and the sub-fenders and transmits the impact force when the ship contacts the sub-fenders to the main fenders. Therefore, when a ship touches or collides with the auxiliary fenders, the main fenders can provide a fouling effect without hindrance, and the auxiliary fenders can be installed with the other fenders concealed. Therefore, it can be installed in a play facility such as a simulated waterway where a simulated ship navigates without a sense of incongruity.
[0024]
In particular, since the fender according to the first aspect of the present invention employs a horizontal truss made of a main material and one-to-two lattice material as a frame, the impact force when the ship contacts or collides with the sub-fender is Dispersed from the auxiliary fender by the lattice material and transmitted to the main material, and transmitted from the main material over the entire length of the main fender, so that the total length of the main fender contributes to buffering and has an excellent fender effect. can get.
[0025]
In the fender according to the second aspect of the present invention, the support for supporting the frame is provided in a state that can be raised and lowered on the main fender, so that when the ship contacts or collides with the auxiliary fender, Therefore, it is possible to transmit the impact force to the main fender without failing without any excessive bending force or moment being applied to each column.
[0026]
The fender according to the invention of claim 3 is a simulated revetment in which the revetment structure, the main fender material, and the frame are concealed behind the simulated revetment structure provided at the front of the revetment structure, and only the auxiliary fender material is hidden. Since it is exposed at the front of the structure, it can be installed in amusement facilities without a sense of incongruity, and the impact force at the time of ship collision can be reliably received by the original revetment structure. Since there is no concern about contact with the armor, it is not necessary at all to have strength against fenders, and it is sufficient to use a dummy, and from the above, it is optimal to be applied to a playground in a theme park.
