Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an asphalt pine hanging device.

<Prior Art> Asphalt pine is used to cover the surface of reclaimed revetments in order to prevent soil from flowing out from reclaimed revetments, to prevent soil from being sucked out, to prevent rubble foundations from being scoured, etc.

The above-mentioned asphalt pine is a large and heavy thin plate whose main component is an asphalt mixture using glass fiber, cloth, sisal rope, etc. as a core material. A plurality of wire ropes for hanging are provided on both sides of the mat.

In order to suspend the asphalt pine and place it on the reclaimed revetment while maintaining it in a substantially horizontal state without curving, asphalt is placed below a flat hanging plate having approximately the same external dimensions as the asphalt pine. Suspend the mat. At this time, the suspension plate is suspended by, for example, a crane via a wire rope, and the asphalt mat is suspended from the suspension plate via the wire rope.

Then, by operating the crane, the asphalt pine is moved with the hanging plate above the reclaimed seawall, and then they are moved down to place the asphalt pine on the reclaimed seawall, and the wire rope is suspended via the hanging plate and the asphalt pine. I try to remove it from the bottom plate.

<Problems to be solved by the invention> However, in the past, asphalt pine is suspended from a single flat hanging plate, so for example, the top of the asphalt pine changes into a slope or steps. The following problems arose when installing a piece of asphalt pine on a reclaimed seawall.

In other words, if the asphalt pine is placed on the reclaimed revetment with the asphalt pine suspended from the suspension board, the asphalt pine will be placed in contact only with the highest part of the reclaimed revetment, and in the lower part, the asphalt pine and the reclaimed revetment will overlap. A predetermined gap will be created between the bank and the seawall. For this reason, in the past, a part of the asphalt pine was placed on the highest part of the reclaimed seawall, and the remaining part was removed from the wire rope in mid-air to allow the asphalt pine to fall. Also,
The entire asphalt pine tree was released in the air and allowed to fall onto the reclaimed seawall.

However, when the asphalt pine is dropped in this manner, the asphalt pine is heavy, making the work of laying the asphalt pine dangerous, and the asphalt pine is easily damaged. Also,
Once dropped, it was difficult to place the asphalt pine in a predetermined position.

The present invention was made in view of the above-mentioned circumstances, and an object of the present invention is to provide an asphalt pine hanging device that can extremely easily lay asphalt pine on a reclaimed seawall that changes from the top to a slope, for example.

<Means for solving the problem> For this reason, the present invention arranges a plurality of plate-like structural members in a flat form, and lowers the edges of these adjacent plate-like structural members with a maximum allowable range of 180°. A plurality of plate-like structural members are connected in a series so as to be freely expandable at the side, and the plurality of connected plate-like structural members and the asphalt mat below are interconnected in a detachable manner by a locking member, and any of the plurality of plate-like structural members are can be freely attached to and detached from the transport device using a flexible member.

<Function> As a result, for reclaimed seawalls that change from the top to the slope, the components of the hanging device are rotated and bent at the position where the angle changes, and the asphalt pine is moved between the top and the slope. Now it can be placed by touching it.

<Example> An example of the present invention will be described below based on FIGS. 1 to 6.

In FIG. 1, a pair of plate-shaped structural members 1a,
1b are each independently framed by linear members 2 such as pipes and formed into a substantially rectangular shape.
A plurality of first brackets 3 are attached to the edge of the first flat plate component 1a, and a plurality of first brackets 3 are attached to the edge of the first flat plate component 1b.
A second bracket 4 is also attached to the edge of the bracket 3.
Multiple units are installed facing each other. A first bracket 3 and a second bracket 4 facing each other are rotatably connected by a pin 5 as shown in FIG. 2, and a hinge member 6 is constituted by the first and second brackets 3, 4 and the pin 5. . Thereby, the component 1a of the first flat plate and the component 1b of the second flat plate are connected to each other so as to be freely rotatable about the pin 5.

Disc-shaped stopper members 7a and 7b are provided at the edges of the first and second flat plate components 1a and 1b, respectively, so as to face each other. The stopper members 7a and 7b come into contact with each other when the structural members 1a and 1b form a substantially flat plate, and from this state the structural members 1a and 1b are rotated upward in FIG. On the other hand, both component members 1a and 1b are configured to be able to expand freely with a maximum allowable range of 180 degrees on the lower side.

Further, the constituent members 1a of the first flat plate and the second flat plate,
Crane wire rope locking members 8 for locking wire ropes 11 as flexible members are attached at predetermined intervals to the upper edge of 1b, and the wire rope locking members 8 for locking wire ropes 11 as flexible members are attached at predetermined intervals to the lower edge of the wire rope locking members 8 as shown in FIG. Asphalt mat wire rope locking members 9 serving as locking members are attached at predetermined intervals. Furthermore, supporting legs 10 are erected at the lower portions of the first and second flat plate constituent members 1a and 1b, respectively.

Next, the operation will be explained based on FIGS. 3 to 6.

As shown in FIG. 3, the ends of the wire ropes 11 are respectively locked to the crane wire rope locking members 8, and the wire ropes 11 are locked to the hooks 12 of a crane serving as a transport device, and a pair of structural members 1a are connected. , 1b are suspended and supported approximately horizontally by a crane. Further, the ends of the wire ropes 13a provided at the peripheral edge of the asphalt mat 13 are respectively locked by the asphalt mat locking members 9.

Then, the pair of structural members 1a,
The asphalt pine 13 is suspended and moved together with 1b, etc., and the pin 5 is disposed above the position where the top end 14a of the reclaimed seawall 14 changes to the slope 14b. When hanging this, asphalt pine 1
3 and the flat plate try to rotate around the pin 5 due to their own weight, but since the stop members 7a and 7b of each component 1a and 1b are in contact with each other, these components 1a and 1b are approximately one flat plate and are horizontal. Therefore, the asphalt mats 13 suspended from the structural members 1a and 1b are also kept substantially horizontal.

In addition, as shown in FIG.
is moved downward to bring the asphalt pine 13 into contact with the top of the reclaimed seawall 14. Furthermore, when the structural members 1a and 1b are moved downward by the crane, the wire rope 11 becomes loose, and as shown in FIG. The asphalt mat 13 is brought into contact with the slope 14b. Then, the supporting legs 10 are brought into contact with the upper wall of the asphalt mat 10, and the asphalt mat 13 is
After removing the wire rope 13a provided at the wire rope locking member 9, the structural members 1a and 1b are moved upward by a crane, thereby completing the asphalt mat laying work.

As explained above, Asphalt Mats 13
A pair of structural members 1a,
1b are attached to each other by a hinge member 6 so as to be freely rotatable, and stopper members 7a and 7b are provided to restrict upward rotation of the constituent members 1a and 1b when they are in a substantially flat state. 14a
When laying the asphalt pine 13 on the reclaimed bank 14 that changes from a slope to a slope 10b, the asphalt pine 13 is suspended by the structural members 1a and 1b, and the second flat plate structural member 1b is rotated to adjust the slope of the asphalt pine 13. It can be brought into contact with different top edges 14a and slopes 14b. As a result, the asphalt pine can be laid without being opened in the air and dropped, making the work safer, preventing damage to the asphalt pine, and making the work easier. Further, if the dividing position of the structural members 1a and 1b is appropriately selected depending on the laying position of the asphalt mat, the asphalt mat can be extremely easily arranged at the laying position. In addition, since the asphalt mat 13 can be hung in a substantially flat state when hanging the asphalt mat 13, it is possible to prevent the flexible and heavy asphalt mat 13 from bending during transportation, thereby preventing cracks in the asphalt mat. It is possible to prevent damage such as this from occurring.

In the above embodiment, the component is divided into two parts, but it may be divided into three or more parts.

<Effects of the invention> As explained above, the present invention consists of a device for suspending asphalt pine consisting of a plurality of members, these members are rotatably connected by a hinge member, and adjacent plate-like structural members are Since the edge is formed to be able to expand freely at the bottom with a maximum allowable range of 180 degrees, the asphalt pine can be suspended in places with different slopes such as reclaimed seawalls and come into contact with different parts. be able to. Thereby, the asphalt pine can be laid without dropping the asphalt pine, making the work safer and easier, and also preventing damage to the asphalt pine. Further, since the asphalt mat is held in a substantially flat state during transportation, it is possible to prevent damage such as cracks from occurring in the asphalt mat.
