Description

[Detailed description of the invention] (Industrial application field) The present invention is a barge that is used to form a work platform for various work equipment such as a pile driver on a river or sea, especially a barge that can be divided into multiple parts. This concerns a split type barge.

(Prior art) This main split type barge can be divided into a plurality of barges and towed in units of barge block units, each of which has a narrow width compared to the width of the whole barge. This is convenient when there is a place where the width of the towing route is narrowed by a weir etc., but each barge block must be joined at the work site.

However, as a conventional method for joining the barge blocks in this type of split type barge, for example,
As described in Japanese Patent No. 47152, a method is known in which the lower ends of the joint end faces of both barge blocks are connected to each other by a wedge driven vertically from above the barge. According to this wedge connection method, the lower ends of the barge blocks under water can be joined together by driving wedges from above the barge, which has great advantages in terms of safety and economy compared to methods that involve diving work. However, the conventional wedge joining method as described in the above-mentioned publication has the following problems.

(Problem to be solved by the invention) That is, the lower ends of both barge blocks are simply drawn together using a wedge to tightly connect the joining end surfaces to each other. There is no function to align the two barge blocks connected together in a direction parallel to the joint end surfaces. Therefore, if the play space between the wedge and the wedge driving recess formed on the joint end faces of both barge blocks in the direction parallel to the joint end faces is large, the two barge blocks joined by wedge driving will be There is a possibility that there will be a large deviation in the direction parallel to the joint end face, and in this state of deviation, both barge blocks will be closely connected to each other by the wedge, so the bolts pre-installed at the joint on the upper end side of the barge blocks will Bolt connection work using holes becomes impossible.

Therefore, in the conventional wedge joining method as described in the above-mentioned publication, there is a play space between the wedge and the wedge driving recess formed on the joint end faces of both barge blocks in a direction parallel to the joint end faces. must be made as small as possible, but no matter how small this play space is, the position of both barge blocks will shift within the range of the play space, so the bolt connection work on the upper end of the barge block is This will be an extremely difficult task. Moreover, the smaller the play space is, the more difficult it becomes to align the large and heavy barge blocks floating on the water with great precision in the direction of the joint end faces. .

(Means for Solving the Problems) The present invention has been made to solve the above-mentioned conventional problems, and its features will be described below with reference numerals in the embodiments. Wedge driving recesses 8, 9 are formed in the lower halves of the joint end surfaces 2a, 2a of each barge block 2, 3 in the barge divided into two, and are adjacent to each other and communicate with each other. 9, one of which is a vertical surface 19 perpendicular to the joint end surfaces 2a, 3a.
a, 20a, and the other wedge action surfaces 19b, 20b are inclined in a horizontal cross-sectional shape so as to approach the vertical surfaces 19a, 20a closer to the joining end surfaces 2a, 3a, and the wedge action surfaces 19b ，
The wedge 20b is inclined downwardly so as to move away from the joining end surfaces 2a, 3a and approach the vertical surfaces 19a, 20a, and the wedge 10 is driven from the barge between the wedge driving recesses 8, 9. A pair of inverted triangular pyramid-shaped wedge portions 21 and 22 are arranged side by side on the left and right, which come into close contact with the vertical surfaces 19a and 20a and the wedge action surfaces 19b and 20b of each of the wedge driving recesses 8 and 9 when driven to a predetermined depth. , the upper halves of the joint end faces 2a and 3a of the barge block are connected to each other by a splicing plate 1.
The main feature is that the bolts are connected via bolts 1 and 12.

(Operation of the invention) According to the above structure, when the barge blocks 2 and 3 are joined to each other, the joint end surface 2 of both barge blocks
With both barge blocks 2 and 3 in contact with each other so that the wedge driving recesses 8 and 9 formed in the wedge driving recesses 8 and 9 formed in a and 3a are in contact with each other, the wedge driving recesses 8 and 9 are Drive wedges 10 over the barge from above.

However, the pair of left and right inverted triangular pyramidal wedge portions 21 and 22 of the wedge 10 correspond to the wedge action surfaces 19 in the respective wedge driving recesses 8 and 9 of the barge blocks 2 and 3.
b, 20b at the same time, the wedge action surface 19
b, 20b, the lower the joint end surface 2a,
The wedge action caused by the inclination component in the direction away from 3a draws the lower halves of the joint end surfaces 2a and 3a of both barge blocks submerged below the water surface toward each other.
When both wedge portions 21 and 22 are driven to a predetermined depth, the joint end surface 2 of both barge blocks is
At this time, the pair of left and right inverted triangular pyramidal wedges 21, 22 are attached to the vertical surfaces 19a, 20a in the respective wedge driving recesses 8, 9. and wedge action surface 19b, 2
0b in a wedge-like manner so as to be in close contact with both surfaces of the wedge driving recesses 8 and 9 so that they cannot move relative to each other in the opposite direction of these surfaces, that is, in the direction parallel to the joining end surfaces 2a and 3a. As a result, it is fixed inside.

In other words, the pair of left and right inverted triangular pyramidal wedge portions 21 and 22 of the wedge 10 not only pull together the lower halves of the joint end surfaces 2a and 3a of both barge blocks 2 and 3 to connect them, but also Ship blocks 2 and 3,
The alignment is performed in a direction parallel to the joining end surfaces 2a and 3a.

In such a state, the upper halves of the joint end surfaces 2a and 3a of both barge blocks 2 and 3 exposed above the water surface are
By bolting together via the splice plates 11 and 12, both barge blocks 2 and 3 can be connected and integrated with each other.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

In FIG. 1, reference numeral 1 denotes a barge, which is divided into two right and left barge blocks 2 and 3 along its longitudinal centerline. Reference numeral 4 designates spats that can be raised and lowered provided at the four corners of the barge 1, and 5 a winch that operates the mooring rope 6 for positioning the barge. Both barge blocks 2 and 3 have joint end surfaces 2a and 3.
They are connected to each other so that they can be joined and separated by a joining means 7 provided between the parts a.

The joining means 7 are arranged at appropriate intervals in the length direction of the joining end surfaces 2a and 3a, and each joining means 7 is arranged between both barges as shown in FIGS. 2 to 4. Joint end surface 2 in blocks 2 and 3

It consists of joining plates 11, 12 and bolts 13, 14 that connect the upper halves of 2a, 3a to each other.

The wedge driving recesses 8, 9 are formed between the bulkhead plates 15, 16 of the barge blocks 2, 3 and the recess forming blocks 17, 18 welded thereto, and as shown in FIG. It has vertical surfaces 19a, 20a formed by the partition plates 15, 16, and wedge action surfaces 19b, 20b formed inside the recess forming blocks 17, 18. More specifically, one of the two side surfaces of each of the wedge driving recesses 8, 9 facing each other in a direction parallel to the joint end surfaces 2a, 3a is a vertical surface perpendicular to the joint end surfaces 2a, 3a. 19a and 20a, and the other is
In the horizontal cross-sectional shape, the joint end surfaces 2a, 3a
Wedge action surfaces 19b, 20b are inclined so as to approach the vertical surfaces 19a, 20a as the side approaches the vertical surfaces 19a, 20a.

It is inclined so as to approach 20a.

As shown in FIG. 5, the wedge 10 has a pair of inverted triangular pyramid-shaped wedge parts 21 and 22 arranged side by side on the left and right, and rods 23 and 24 projecting upward from the upper ends of these wedge parts 21 and 22. As shown in FIGS. 2 to 4, the inverted triangular pyramidal wedge portions 21 and 22 are driven into the wedge driving recesses 8 and 9 adjacent to each other to a predetermined depth. At this time, the respective inverted triangular pyramidal wedges 21 and 22 are connected to the vertical surfaces 19a and 20a of the respective wedge driving recesses 8 and 9 and the wedge action surface 1.

The attachment plate 11 has the wedge driving recess 8,
Both barge blocks 2, 3 are placed in the upper halves of the bulkhead plates 15, 16 facing the wedge driving passage 25 for 9.
It is attached between the partition walls and is fixed to the partition walls 15 and 16 by bolts 13. Further, the attachment plate 12 is attached between the barge blocks 2 and 3 so as to close the upper end opening of the wedge driving passage 25, and is attached to the upper floor plate 2 of the barge block.
6 and 27 with bolts 14.

Note that the upper floor plates 26 and 27 are lowered one step around the upper end opening of the wedge driving passage 25 so that the attachment plate 12 and the bolts 14 do not protrude above the upper floor level of the barge blocks 2 and 3. It is configured.

When joining the two barge blocks 2 and 3, which were separated during towing, to each other as shown in the figure, the wedge driving recesses 8 and 9 connect the joint end surfaces 2a and 3a of both barge blocks 2 and 3. The wedges 10 are placed adjacent to each other so as to communicate with each other from the barge.

However, the pair of left and right inverted triangular pyramidal wedge portions 21 and 22 of the wedge 10 are in sliding contact with the wedge action surfaces 19b and 20b of the respective wedge driving recesses 8 and 9, and the inside of the inclination of the wedge action surfaces 19b and 20b is in sliding contact with each other. , the lower the joint end surface 2
The lower halves of the joint end surfaces 2a and 3a of both barge blocks submerged below the water surface are drawn together by the wedge action caused by the inclination component in the direction away from a and 3a. When both the wedge portions 21 and 22 are driven to a predetermined depth, the lower halves of the joining end faces 2a and 3a of the barge blocks are pulled together and connected, and at this time, the pair of left and right inverted triangles are The conical wedge parts 21 and 22 are connected to the respective wedge driving recesses 8 and 9.

This results in fixation within the wedge driving recesses 8,9.

In other words, the pair of left and right inverted triangular pyramidal wedge portions 21 and 22 of the wedge 10 not only pull together the lower halves of the joint end surfaces 2a and 3a of both barge blocks 2 and 3 to connect them, but also Ship blocks 2 and 3,
The alignment is performed in a direction parallel to the joining end surfaces 2a, 3a.

As mentioned above, the wedge 10 connects the barge block 2,

At this time, the nuts 28 are screwed onto the rods 23 and 24 of the wedge 10 at a height that can support the attachment plate 12, and the rods 28 are
3 and 24 to penetrate the splicing plate 12, and sandwiching the splicing plate 12 between the nut 28 and the nut 29 screwed onto the rods 23 and 24 above the splicing plate 12. By doing so, the wedge 10 can be fixed.

Note that the splice plate 12 was attached to cover the upper end opening of the wedge driving passage 25, and the wedge 10 was fixed to the splice plate 12 via the rods 23 and 24, but the splice plate 11 was The wedge 10 can also be fixed to the horizontally projecting portion of the attachment plate 11 via rods 23 and 24. Of course, wedge 1
Since the 0 is driven into both wedge driving recesses 8 and 9, there is no fear that it will easily come up due to some vibration, so the wedge fixing means as in the above embodiment can be omitted.

(Effect of the invention) As described above, according to the split type barge of the present invention, the lower halves of the jointed end surfaces of the barge blocks that are submerged under the water surface can be easily connected by simply driving a wedge from the top of the barge. It is possible to reliably connect them with a simple operation, but as explained in detail in the previous section (effects of the invention), the wedges are driven in to draw the two barge blocks together, and the joint end surfaces are drawn together. When the wedges are joined together, each of the left and right inverted triangular pyramidal wedge portions of the wedges enter between the vertical surfaces and the wedge action surfaces of the wedge driving recesses of both barge blocks, and thereby It is fixed tightly on both sides.

In other words, the wedge driven into the wedge driving recess to a predetermined depth is parallel to the joint end surfaces of the barge blocks, which are drawn together and connected by the wedge. It will be accurately positioned and firmly fixed at a fixed position in the direction.

Therefore, both barge blocks are attracted to each other and their joint end surfaces are joined together, and at the same time, they are also accurately aligned in the direction parallel to the joint end surfaces, so that the upper halves of the joint end surfaces of both barge blocks are This makes it extremely easy to connect the joining plates and bolts.

Furthermore, by driving the wedge, both barge blocks can be automatically aligned in a direction parallel to the joint end surfaces, so that the above-mentioned position between the upper end opening of the wedge driving recess and the lower end of the wedge can be automatically aligned. Make the play space in the direction parallel to the joint end surface sufficiently wide,
Even if the amount of positional deviation in the direction of the joining end surfaces of both barge blocks before driving the wedge is large, the wedge can be driven easily and easily. In other words, high precision is no longer required in the positioning work of the two barge blocks on the water before the joining work, and the work can be performed easily and efficiently.
