Is a flange 2 extending inward and horizontally
7 are formed, and the flanges 26 and 27 are overlapped and connected to each other. And this flange 26,
The buffer member 4 is interposed between the flange 27 and the flange 31 of the hatch combing 3 and connected to the flanges 26, 27 and the flange 31 by bolts 91, 92, respectively.

Outside the cushioning member 4, there is provided a sealing means 5 for sealing between the periphery of the bridge main body 2 (the lower part of the peripheral wall 22) and the hatch combing 3 rising from the deck 11. I have. This sealing means 5 is made of FR
It is composed of a waterproof cover 53 made of a plate material having a certain degree of rigidity and elasticity such as P, and a seal plate 54 made of a highly flexible plate material such as a rubber plate disposed inside the waterproof cover 53. The waterproof cover 53 is formed in a belt-like body so as to surround the entire lower end of the peripheral wall 22, and the upper end thereof is
A seal member 530 that is fixed to the lower portion of the peripheral wall 22 and abuts against the side surface of the hatch combing 3 is attached to the inside of the lower edge of the waterproof cover 53, thereby sealing between the peripheral edge of the bridge body 2 and the deck 11. ing. The upper end of the seal plate 54 is fixed by being sandwiched between the lower end of the peripheral wall 22 and the waterproof cover 53, and the lower end is screwed to the upper end of the hatch combing 3. A seal is provided between the periphery of the second and the deck 11 so that a double seal is provided.

The rear part of the bridge body 2 is configured as shown in FIG. That is, a rising wall 201 is formed at the rear end of the floor plate 20, a flange 202 extending horizontally rearward is formed at the upper end thereof, and a reinforcing material 203 made of wood is attached to the lower side thereof with screws. A sash frame 231 is mounted on the reinforcing member 203, and a slide door 232 for entering and exiting the bridge is mounted on the sash frame 231. Also, the upper end of the waterproof cover 53 and the seal plate 54 are attached to the rear surface of the reinforcing member 203 in the same manner as described above, and the lower end of the waterproof cover 53 contacts the rear surface of the hatch combing 3 with the seal member 530.
The lower end of the seal plate 54 is fixed to the hatch combing 3 by screwing. And this reinforcing material 203
A gap is formed between the flange 32.

The buffer member 4 is configured as shown in FIG. That is, the lower holding member 41 made of a metal having a V-shaped cross section and the corresponding upper holding member 42 made of a metal having a V-shape opposing each other at a predetermined interval,
A cushion portion 43 made of V-shaped rubber is interposed between them, and a crescent-shaped space 44 is formed at the center of the cushion portion 43, and has a uniform sectional shape in the front-rear direction (perpendicular to the paper surface). And its dimension is formed slightly smaller than the dimension in the left-right direction (ship width direction). Then, in the mounted state of the bridge main body 2 (the state where the load of the bridge main body 2 is applied), the cushion portion 43 is compressed and the space 44 is crushed as shown in FIG. Is configured.
Bolts 91 and 92 are integrally attached to the upper holding member 42 and the lower holding member 41, respectively, so that the bolts 91 and 92 can be attached to the hull and the bridge body. The spring constant of the buffer member 4 is configured such that the ratio of the vertical direction: the boat width direction: the front-rear direction is 5: 4: 1 in this example. This is because, in the case of a ship, the vibration in the front-rear direction is very small with respect to the vibration in the width direction of the ship, so that the vibration is adapted.

In the above construction, the vibration generated in the hull 1 by the driving of the engine 14 is transmitted from the hatch combing 3 to the buffer member 4, and the vibration member 4 reduces the vibration in both the vertical direction and the boat width direction. It will be absorbed efficiently. That is, the vertical vibration is applied to the cushion portion 43 of the cushioning member 4 as a large or small compressive force and is absorbed by the cushion portion 43, and the vibration in the boat width direction is also absorbed by the V-shaped upper and lower holding members 41 and 42. 4 is given and absorbed as a large and small compressive force. Further, although the spring constant with respect to the vibration in the front-rear direction is small, this vibration is small as compared with the vibration in the width direction of the boat, so that the above configuration can sufficiently absorb the vibration.

Further, since the sealing means is provided between the peripheral portion of the bridge body and the deck, it is possible to prevent the water launched on the deck from entering the lower side of the bridge body. In particular, since the sealing means 5 is composed of the waterproof cover 53 formed of a band surrounding the periphery of the bridge main body and the sealing member 530 provided inside the lower end thereof, the deck 11 which is relatively displaced by vibration is provided. The sealing means as means for sealing with the bridge main body 2 can have a simple configuration. Further, since the cushioning member 4 is covered by the sealing means 5, it is possible to prevent seawater from splashing on the cushioning member 4, and it is possible to improve the durability of the cushioning member 4.

Further, since the bridge body 2 is mounted on the upper surface of the hatch combing 3, which is a protrusion formed on the deck 11, via the buffer member 4, the support portion on which the buffer member 4 is installed is reinforced. There is an advantage that it is easy to seal this part. Moreover, the opening 10
Hatch combing 3 forming the edge of the bridge body 2
, It is not necessary to separately provide a receiving portion for the bridge main body 2, and space and members are effectively used.

FIGS. 9 to 13 show another embodiment of the present invention. The basic structure of the hull 1 and the bridge body 2 is the same as that described above, but the structure of the buffer member is different. That is, the cushioning member 7 is made of a material having high elasticity such as rubber, and is formed in a planar rectangular shape along the flanges 31 and 32 serving as receiving portions of the bridge body 2.
In addition, the rear portion is formed to be lower along both surfaces of the flange 31 and the flange 32, and the cross-sectional shape is shown in FIG.
As shown in FIG. The buffer member 7 is interposed between the flanges 26 and 27 of the bridge main body and the flange 31 of the hatch combing 3 and is fastened and connected at appropriate intervals by bolts 94 penetrating vertically.

In the above-described configuration, the buffering means 7 has a function of damping the bridge main body 2 and also has a sealing function of preventing water launched on the deck 11 from entering the lower side of the bridge main body 2. be able to.

An example is shown in which the outside is double-sealed with a waterproof cover 53 and a seal plate 54.

FIG. 15 shows an example of the peripheral wall 22 of the bridge body 2.
Form a flange 28 projecting outward at the lower end of the
The flange 28 is received via the cushioning member 4 installed on the deck 11 outside the hatch combing 3. A band-shaped sealing plate 58 for sealing between the flange 28 and the deck 11 is attached to the outside thereof, and the flange 31 of the hatch combing 3 and the floor plate 20 of the bridge body 2 are attached.
The seal member 59 is interposed between the peripheral portion and the flange 29 to form a double seal.

In the example shown in FIG. 16, no opening or protrusion is formed in the portion of the deck 11 where the bridge body is installed, and the cushioning member 4 is installed on the flat deck 11 and the flat floor plate is placed thereon. A bridge body 2 having 20 is installed. A seal plate 54 is provided outside the cushioning member 4 to seal between the periphery of the bridge body 2 and the deck 11.

In the example shown in FIG. 17, the deck 11 has no opening, and a projection 35 having a planar shape corresponding to the planar shape of the bridge main body 2 is formed. A cushioning member 7 is provided, and a flange 29 on the lower peripheral portion of the bridge body 2
Are mounted and connected by bolting in the same manner as described above. The cushioning member 7 performs both functions of absorbing vibration and sealing the lower side of the bridge body 2.
