Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a belly plate for docks.

[Conventional technology]

Traditionally, the boards installed on the bottom of the ditch are
For example, as shown in the sectional view in Figure 4, there is a main board B that supports the centerline part of the bottom A and a belly board C that supports the side parts, and the belly board C is shown in the partially enlarged view in Figure 5. As shown, large wedge-shaped inclined boards C2 and C are placed on a large rectangular steel board C1 placed on the ditch bottom D.
2. Constructed by stacking wooden arrows C3 and blocks C4 in sequence, and joining steel blocks C1 and inclined blocks C2, C2 with fixing jig C5, and inclined blocks C2 and blocks C4 with casing C6, respectively. has been done.

If the bottom A of the ship supports a flat ship,
As shown in the right half of Figure 4, the main board B and the belly board C
When supporting a ship whose bottom A is sloping with the same height, the height of the belly board C is adjusted by the board C4, as shown in the left half of the figure.

However, such a structure has the following disadvantages when the height of the belly board C is adjusted using the board C4 when ships with different inclinations of the bottom A continue to dock.

(1) Once the inside of the dock is drained and the height adjustment work of the base tree C is performed, extra power costs for drainage and extra time for draining and water injection will be required.

(2) Board C4 prepared in advance on the ditch bottom D
If a diver were to perform the replacement work underwater, it would be hard work for the diver due to the poor working environment underwater.

[Problem that the invention attempts to solve]

The present invention has been proposed in view of the above circumstances, and an object of the present invention is to provide a dock base board that allows for economical and easy height adjustment of the base board.

[Means for solving problems]

To this end, the present invention provides a dock base board in which a plurality of lower boards and upper boards are sequentially stacked on top of a steel board. A pair of front and rear link members are respectively pivotally connected to the front and rear surfaces of the upper board, and when the upper board is not in use, the link member is rotated to a side position of the steel board via the link member. It is characterized by what it did.

[Effect]

With the above-described structure, it is possible to obtain a dock base board that allows for economical and easy height adjustment of the base board.

〔Example〕

An embodiment of the present invention will be explained with reference to the drawings.
Figure 1 is a perspective view, Figure 2 is a front view of Figure 1,
FIG. 3 is a side view of FIG. 1.

In the above figure, the same symbols as in Figs. 4 and 5 indicate the same members as in the same figure, and 1 is a large rectangular steel board placed on the culvert bottom D;
A normal board 2, a rubber board 3, a normal board 2, an inclined board 4, and a board 5 are stacked in this order on top of the board.

The rubber 3 is a height adjustment member using elasticity, and the inclined board 4 is painted white.

6, 6 are a pair of front and rear connecting rods for locking the inclined board 4 to the steel board 1; They are each pivotally supported at the lower part of the front and rear surfaces of the board 4.

Reference numeral 7 denotes a casing for fixing the normal boards 2, 2, the inclined boards 4, and the boards 5 to each other in sequence.

In such a structure, if a ship with a sloping bottom A enters the dock next to a ship with a flat bottom A, the ship with a flat bottom A is placed on a normal board 2 stacked on a steel board 1. , 2 and docked, a steel board 4 is installed in advance to fit a ship that is anchored by the connecting rod 6 and has an inclined bottom A, as shown by the broken line in Fig. 1. Place it against the side of Tree 1.

Then, when the ship with a flat bottom A has left the dock, a diver descends onto the bottom D of the culvert and uses the buoyancy of the sloping board 4 and the linking action of the connecting rod 6 to
are rotated and stacked on the normal board 2, and then the ship with a sloping bottom A is docked.

If a ship with a flat bottom A enters the dock next to a ship with a sloping bottom A, the procedure is the reverse of the above.

According to such a structure, the following effects can be achieved.

(1) There is no need to drain the dock and adjust the height of the boards before a ship enters the dock with a bottom slope different from that of the previous ship, which saves power costs for draining and draining time. can.

(2) Since a diver can attach or remove the slope board underwater by using the buoyancy of the slope board and the rotational movement of the link, the work becomes stable, safe, and easy.

[Effect of idea]

In short, according to the present invention, in a dock base board formed by sequentially stacking a plurality of lower boards and upper boards on a steel board, the lower end is placed on the upper part of the front and rear surfaces of the steel board, and the upper end is each has a pair of front and rear link members pivotally connected to the front and rear surfaces of the upper board, and when the upper board is not in use, the link member is rotated to a side position of the steel board through the link member. As a result, the present invention is industrially extremely useful because it provides a dock base board that allows for economical and easy height adjustment of the base board.

Claims (1)

[Scope of utility model registration request] In a docking belly board made by sequentially stacking a plurality of lower boards and upper boards on a steel board, the lower ends are at the tops of the front and rear surfaces of the steel boards, and the upper ends are at the front and rear sides of the upper boards, respectively. It is characterized by comprising a pair of front and rear link members pivotally connected to the surface, and when the upper board is not in use, these can be rotated to a side position of the steel board via the link members.
