2. Description of the Related Art A conventional floating bridge is disclosed in Japanese Unexamined Patent Publication No. 60-95007.
In order to increase the effective width of the bridge in the erected state and to reduce the width when folded and transported, the height of the auxiliary floating body during deployment is lower than the height of the main bridge body as described in Thus, the side end portion is prevented from being covered with a wave by a rotatable wave holding member.

[0003]

In the prior art, since the height of the auxiliary floating body is lower than that of the main bridge body at the time of deployment, when the sinking amount exceeds the height of the auxiliary floating body, the above-mentioned conventional technique requires the rotation of the rotating wave holding plate. There was a possibility that the submerged body would sink below the water surface due to water from the gap, and the flat part on the upper surface of the auxiliary floating body could not be used as a sidewalk. Also, when connecting a power boat after deploying the floating bridge, pushing the tip of the wave holding member was a problem in strength.

An object of the present invention is to solve the above-mentioned problems and to make it possible to adjust the height of a wave breaking plate for holding a wave according to the settlement amount of a floating bridge.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. The floating bridge is constructed by connecting two main bridges 2 which also serve as a floating body with a submerged portion which is watertight by a center hinge 1, and an auxiliary floating body 4 via hinges 3 and joints 12 on both sides thereof. ing. As shown in the figure, the vehicle 5 crosses the upper surface of the main bridge 2 in a deployed and bridged state.

A guide 7 for a traveling wave cutting plate 8 is provided on a side portion 6 of the auxiliary floating body, and a locking hole 9 provided in the traveling wave cutting plate 8 is provided.
And a locking pin 10 provided on a flange protruding upward at the side portion 6 of the auxiliary floating body.
At the time of transportation, the moving wave cutting plate 8 is lowered.

According to such a configuration, even if the water depth of the river is shallow, the flow velocity is large, the buoyancy is reduced, and the amount of settlement is increased, the moving wave cutting plate 8 is raised in the direction of arrow A shown in the figure. Thereby, the fogging phenomenon can be prevented .
In addition, the guide 7 and the wave-cutting plate 8 are attached to the side 6 of the auxiliary floating body.
Since it is covered, it usually serves as a cushioning material for driftwood and the like to help prevent the auxiliary floating body side portion 6 from being damaged. In addition, the wave cutting plate 7 is
Since the guide 6 is moved up and down, it can be easily moved up and down.
Things.

The auxiliary floating body 4 is generally made of an aluminum alloy material or a stainless steel material.
By using FRP (fiber reinforced plastic) rather than using an aluminum alloy or stainless steel of the same material as the auxiliary floating body 4, the weight can be reduced and handling becomes easier.

In the embodiment shown in FIGS. 3 and 4, a slidable wave-cutting plate is multiplexed (multi-stage). That is, after bridging, if necessary, the slidable wave cutting plates 8, 8 ', 8 "are sequentially mounted on the auxiliary floating body side portion 6 as shown in FIG. Since the height can be increased, the sinking amount can be allowed up to the vicinity of the upper portion of the auxiliary floating body side portion 6, and the wave breaking plates 8, 8 ', 8 "have a multi-layer structure, so that the strength against waves is excellent.

The embodiment shown in FIGS. 5 and 6 will be described. Reference numeral 18 denotes a moving wave cutting plate in which a wave cutting plate portion and a diagonal member are integrated, and 1
7 is a diagonal member of the auxiliary floating body 4, 16 is a rod having a length adjusting mechanism 21, and 19 and 20 are mounting hinges of the rod 16.

The difference between this embodiment and the above embodiment is that the moving wave cutting plate 18 in which the wave cutting plate and the diagonal member are integrated is slid along the diagonal member 17 of the auxiliary floating body 4. That is.

With this configuration, the width of the floating body can be increased by sliding the moving wave cutting plate 18 as necessary after the bridge, so that the buoyancy can be increased.
A vehicle heavier than the above embodiment can be passed.

If the traveling wave cutting plate 18 is processed into a shape having a bead along the traveling direction of the vehicle, the traveling wave cutting plate 18 is strengthened against out-of-plane loads, and thus is strengthened against driftwood and the like.

The embodiment shown in FIGS. 7 and 8 will be described. After the bridge is bridged, the wave-cutting plate 28 is unfolded in the state shown in FIG. 7, and the foldable (two-fold) stays 24 attached to the hinges 23 are straightened. The structure is joined as shown in FIG. In addition,
The auxiliary floating body side 6 and the wave-cutting plate 28 are connected by a hinge 30.

With such a configuration, the wave-cutting plate 28 can be made high, and even if the settlement amount becomes large, no wave fogging occurs.

The embodiment shown in FIGS. 9 and 10 will be described. The difference between this embodiment and the above embodiment is that a part of the deck of the auxiliary floating body is used for the folding type wave-cutting plate. After the floating bridge is deployed and bridged, in the state of FIG. 9, the stopper 32 is removed, the deck 31 is erected along the side of the auxiliary floating body 6, and the stay 36 is extended linearly and supported, as shown in FIG. Constitute. In the figure, reference numerals 33, 34, and 35 denote hinges for joints of the members, 15
Is a space part.

With this configuration, the deck 31
Can be used as a wave cutting board, and the space 15 can be used for storing tools and tools.

In the embodiment shown in FIG. 11, the corrugated plate is made detachable, and a corrugated plate having a desired height is attached according to the amount of settlement. 44 is a main wave cutting plate disposed on the side 6 of the auxiliary floating body 4, 45 is an auxiliary wave cutting plate, 46 is a supporting portion of an auxiliary wave cutting plate 45 disposed below the main wave cutting plate 44, and 47 is an auxiliary wave cutting plate. A rubber plate 48 is provided at a contact portion of the wave cutting plate 45 with the main wave cutting plate 44, and bolts 48 fix the auxiliary wave cutting plate 45 to the main wave cutting plate 44.

In such a configuration, when the floating body is used at a high flow velocity, the auxiliary wave cutting plate 45 is disposed above the main wave cutting plate 44. The auxiliary wave cutting plate 45 hooks an inverted L portion 45a extending from the auxiliary wave cutting plate 45 on the support portion 46 provided on the side portion 6 of the auxiliary floating body 4 and the upper portion of the main wave cutting plate 44.

A rubber plate 47 or an elastic body similar thereto is stretched over the entire contact portion of the auxiliary wave cutting plate 45 with the main wave cutting plate 44. In this case, the rubber plate 47 is provided with a taper so that the thickness increases as going upward from the lower part. By arranging the auxiliary wave cutting plate 45 in this way, even if the flow velocity increases and the wave making height increases, the auxiliary wave cutting plate 45
Thus, it is possible to prevent water from flowing into the upper surface of the floating body. here,
The contact portion between the main wave cutting plate 44 and the auxiliary wave cutting plate 45 is completely adhered by the tapered rubber plate 47, so that it is possible to minimize the inflow of water even when the wave height is higher than the joint. it can. Further, the force acting on the auxiliary wave cutting plate 45 can be supported by the contact portion between the support portion 46 and the main and auxiliary double wave cutting plates 44 and 45 above the main wave cutting plate 44. Removal of the auxiliary wave cutting plate 45 can be easily performed only by lifting the auxiliary wave cutting plate 45 itself. As described above, according to the present embodiment, the auxiliary floating body 4 can be efficiently used as it is in its original shape in a normal operation state, and can appropriately respond to a high flow velocity as appropriate.

FIG. 12 shows that support rods 45b are disposed at appropriate intervals below the auxiliary wave cutting plate 45, and the support rods 45b are inserted into a pipe 49 provided outside the main wave cutting plate 44 to cut the auxiliary wave. The plate 45 is fixed to the main wave cutting plate 44. This embodiment also has the same effect as the above-described example.

The embodiment shown in FIG. 13 will be described. A deployment position adjuster 51 is provided between the main bridge 2 and the auxiliary floating body 4, and the auxiliary floating body 4 on the upstream side is rotated by using the deploying position adjuster 51, and the tip 6 is appropriately lifted upward. At this time, the main bridge 2 and the auxiliary floating body 4
The auxiliary floating body 53 is expanded in a gap formed between the auxiliary floating body 53 and the exhaust gas of a simple compression cylinder, a compressor or a transport vehicle. As the deployment position adjuster 51, a jack, a turnbuckle, or the like is used. Thereby, the auxiliary floating body 4 becomes higher above the water surface without lowering the buoyancy.
Therefore, even if the flow velocity of the river increases, the auxiliary floating body 4 does not cover the waves due to the wave making, and the operation range is expanded.

Here, the auxiliary floating body 53 may be first lifted appropriately by the above-described method, and then fixed by the deployment position adjuster 51. If you do this,
Since the auxiliary floating body 4 can be easily lifted and the gap between the main bridge body 2 and the auxiliary floating body 4 can be reliably kept closed, there is an effect that buoyancy does not decrease.

The auxiliary floating body 53 may be of a bellows type. In this case, the auxiliary floating body 53 is used before the main bridge 2 or the auxiliary floating body 4 is removed from the floating bridge.
Can be easily attached by previously disposing them on one of the side surfaces with which each of them contacts.
