Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is used, for example, on seawater such as the sea, rivers and lakes, or on soft ground containing a large amount of water such as marshland or mud. The present invention relates to a floating structure using an ultra-lightweight connection block.

[Conventional technology]

Conventionally, civil engineering works and the like may be performed as necessary, for example, on a sea surface such as the sea, a river, or a lake, or on a soft ground containing a large amount of water such as a bog or mud. is there.

When construction is performed in such a place, the work scaffolding on the sea surface or soft ground is very bad and construction cannot be performed as it is, so the work scaffold is built before starting construction. You.

In civil engineering work, for example, construction materials such as concrete, gravel, rebar, and installation equipment and various civil engineering machines are used at the construction site, so these materials and work machines must be brought to the construction site. Therefore, it is necessary to secure a passage for transporting these materials and working machines to the construction site.

If there is a place with poor scaffolding such as the sea surface or soft ground on the transport path to the construction site, temporary bridge girders will be erected, and there will be no obstacle to transporting construction materials and civil engineering machinery. It is planned as follows.

[Problems to be solved by the invention]

However, in the work for constructing the work scaffold described above, a large number of support materials are driven into the sea surface or soft ground, or the support materials are assembled, and, similarly,
Even when temporary embankments, bridge girders, etc. are erected on places with poor scaffolding, supporting materials for supporting bridge girders, etc., were driven into the seawater or soft ground at regular intervals. As a result, a large amount of materials, labor, time, and the like are required for the work, so that there is a problem that the cost of the entire construction is increased and the construction period is lengthened.

In addition, after the construction is completed, these facilities will be dismantled or left as they are, but when dismantling the facilities, it is not possible to dismantle easily in a short time, and when leaving the facilities However, there is a problem in that the equipment cannot be reused and the materials used are wasted, and in any case, the cost is relatively high.

Further, in the above case, for example, it is conceivable to carry a floating boat on the sea surface or soft ground and use the floating boat as a scaffold or a temporary bridge girder, but the sea surface is surrounded by land. In the case of lakes, shallow shores on the way, or on soft ground, floating boats cannot be towed to the site, and must be transported overland to transport floating boats. It was not easy to transport a heavy floating ship to such a place via land, and when the water was shallow, the ship would sink into the ground due to its own weight at low tide. there were.

The present invention has been made in view of the above-described problems, and has been made in order to solve the problems. The purpose of the present invention is to construct a work scaffold, for example, on a sea surface or on soft ground. Work supporting floating structures such as bridge girders are composed of floating structures consisting of a connected assembly of ultra-light connecting blocks that are easy to connect and disassemble, enabling quick and easy construction and disassembly, and enabling extra materials. As little as possible,
To provide a floating structure using an ultra-light connection block that can be repeatedly used while preventing corrosion of the ultra-light connection block, is easy to transport, and can reduce friction with soft ground. is there.

[Means for solving the problem]

In order to achieve the above object, a floating structure using the ultra-light connection block according to the present invention forms an ultra-light connection block by covering the outer surface of the block made of an ultra-light material with a corrosion-resistant covering material. At the same time, the ultra-light connection blocks are connected in the left-right, front-rear, and up-down directions, and each communication on the same extension line formed at the same position in the left-right, front-rear, and up-down directions of each ultra-light connection block A high-tension piano wire is inserted into the hole, and both ends of the inserted high-tension piano wire are protruded from the respective ultra-light connection blocks, and are connected integrally by fastening with nuts.

Here, as a preferred embodiment, the floating structure using the ultra-light connection block preferably has a configuration floating on the sea surface or on soft ground containing a large amount of water, and the ultra-light connection. It is preferable to coat the bottom surface of the floating structure using the block with a material having a small coefficient of friction.

[Action]

The present invention having the above configuration operates as follows.

In other words, in each communication hole on the same extension line drilled at the same position in the left and right, front and rear, and up and down directions of the ultra-light connection block,
The high tension piano wire is inserted, and both ends of the inserted high tension piano wire are projected from each ultra-light connection block and tightened with nuts to connect, so that each ultra-light connection block can be firmly connected. And the use of high-tension piano wire, the diameter of each communication hole can be as small as necessary.Moreover, when inserting the piano wire, it can be used alone without the help of other parts. It works so as to insert the connection hole.

Moreover, since it is a floating structure, it can be used on seawater or soft ground, and acts to reduce the number of members that support it.

Further, since the bottom surface of the floating structure is coated with a material having a low coefficient of friction, the floating structure acts to make it easy to slide on soft ground.

〔Example〕

Hereinafter, the present invention will be described more specifically based on embodiments shown in the drawings.

Here, FIG. 1 is a partially cutaway side view of the ultra-light connection block.

In the figure, an ultra-light connection block 1 has a rectangular parallelepiped shape, and an ultra-light material 2 made of, for example, styrene foam having a specific gravity of 0.02 or more is provided inside. The ultralight material 2 has a rectangular parallelepiped shape similar to the ultralight connection block 1, and the entire outer surface of the ultralight material 2 consisting of six surfaces is completely covered with the anticorrosion coating material 3. For this reason, the ultra-light material 2 is prevented from being corroded by the anticorrosion coating material 3.

As the anticorrosion coating material 3, a corrosion-resistant metal material, a vinyl material, a plastic material, an FRP material, a durable resin material, a rubber material, wood, or the like can be used. In short, a material having an anticorrosion function is used. In addition, a material that is as light as possible and has the strength to withstand a predetermined external force is preferable. This anticorrosion coating material 3
The materials used are, for example, corrosion-resistant metal materials, vinyl materials,
In the case of a plastic material, an FRP material, a durable resin material, a rubber material, wood, or the like, it is bonded to the outer surface of the ultralight material 2 with an adhesive.

The ultra-light connection block 1 is provided with an ultra-light material 2 inside and an anticorrosion coating material 3 on its outer surface. The specific gravity of the ultra-light connection block 1 is always 1 or less. The relationship between the volume and specific gravity of the ultralight material 2 and the volume and specific gravity of the anticorrosion coating 3 is taken into account.

 FIG. 2 is a perspective view of the floating structure.

The floating structure 8 is composed of a connected aggregate of a number of ultra-light connecting blocks 1. In the floating structure 8 shown in FIG. 2, the ultralight connection blocks 1 are connected in the left and right, front and rear, and up and down directions. Each super-light connection block 1
There are communication holes for connection at the same position in the left, right, front and back and up and down directions respectively, and each communication hole on the same extension line is inserted with a high tension piano wire, and Each of the ultra-light connecting blocks 1 is tightened with nuts at both ends of the high tension piano wire projecting from the light connecting block 1.
To form a floating structure 8.

In addition, the disassembly of the floating structure 8, that is, the disconnection can be achieved only by removing the nut that has fastened the high-tension piano wire and pulling out the high-tension piano wire from the communication hole. After that, just pull out each ultra-light connection block 1,
The floating structure 8 will be dismantled.

FIG. 3 is a side view of the floating structure on the sea surface, and FIG. 4 is a side sectional view of the floating structure on the soft ground.

Since the floating structure 8 has a specific gravity smaller than that of seawater, the floating structure 8 can always float on the sea surface, and there is no need to support the floating structure 8 from underwater.

Similarly, the floating structure 8 placed on the soft ground has a small specific gravity, and can be floated on the soft ground. In this case, when the floating structure 8 is placed on the soft ground, the specific gravity of the floating structure 8 is determined in consideration of the amount of discharged water contained in the soft ground.

Further, the bottom surface of the floating structure 8 placed on the soft ground is coated with a material 8a having a small friction coefficient so as to reduce the frictional resistance with the soft ground. When the floating structure 8 is moved on soft ground, it can be moved smoothly, and the power required for moving the floating structure 8 is reduced.

It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, in the above-described embodiment, the case where the ultralight connection block 1 has a rectangular parallelepiped shape is described. However, the present invention is not limited to this shape. Any shape may be used.

Similarly, the connection structure for connecting the ultra-light connection blocks 1 is not limited to the above-described structure, but may be a structure in which the ultra-light connection blocks 1 adjacent to each other in front, rear, left, right, and up and down are easily connected. Any structure may be used.

〔The invention's effect〕

As is apparent from the above description, according to the present invention, each ultralight connection block can be firmly connected by tightening the nut, and the connection strength is adjusted by adjusting the tightening state of the nut. be able to. Moreover, when disassembling the ultra-light connection block, it is only necessary to remove the nut and pull out the high-tension piano wire, and the disassembly can be easily performed. In addition, since a high-tension piano wire is used, the diameter of each communication hole may be as small as possible.In addition, when inserting the piano wire, a long connection hole is used alone without the help of other parts. Can be inserted.

In addition, a floating structure for work assistance, such as a work scaffold or a bridge girder, which is constructed on the sea surface or on soft ground, is composed of a floating structure comprising a connected aggregate of ultra-light connecting blocks that can be easily connected and disassembled. From this, it is possible to quickly and easily connect and construct the ultra-light connection blocks together,
Further, disassembly after the completion of the construction can be performed quickly and easily. As described above, the work-assisting floating structure can be quickly and easily constructed and dismantled, so that the construction period can be shortened.

Furthermore, since the work-assisting floating structure is a connected aggregate of ultra-lightweight connecting blocks with a small specific gravity that floats on the sea surface or soft ground, unlike a conventional work-assisting structure, Extra materials such as supporting materials for supporting on the sea surface or soft ground and construction costs can be minimized. In addition, since the outer surface of the ultra-light connection block is coated with a corrosion-resistant coating material, the ultra-light connection block can be prevented from being corroded by seawater or substances in soft ground, and the durability of the ultra-light connection block can be reduced. It is possible to increase the number of years and increase the number of times of repeated use after dismantling. As a result, it is possible to significantly save resources and to reduce costs.

In addition, the work-assisting floating structure can be disassembled into a single unit of the ultra-lightweight connection block, which facilitates its transportation and can be transported to places where conventional transportation is difficult. It is possible to significantly expand.

In addition, since the bottom surface of the work-assisting floating structure is covered with a member having low friction resistance, the friction between the bottom surface of the floating structure and the soft ground can be reduced, and the movement of the work-assisting floating structure on soft ground can be moved. Can be performed smoothly, and the power energy for moving the work assisting floating structure can be reduced.
