Description

[Detailed description of the invention] [Industrial application field] This invention relates to a connection structure for sheets,
Mainly used for sheets laid to cover water bottoms, bank slopes, etc.

[Conventional technology and problems] Conventionally, sand and stone blocks on the water bottom, seawall slope, etc.
In order to prevent water from being washed away by currents, waves, etc., flexible and water-impermeable sheets are laid to cover the water bottom, bank slopes, etc. Since the covered area is wide, a plurality of wide sheets are connected together.

The conventional connection structure is, for example, as shown in FIG.
Cable fixing devices 3a and 4a are attached to the connecting ends 2a and 2b of
A plurality of cables 5a are arranged and fixed in the longitudinal direction at appropriate intervals, and the cables 5a extend in the longitudinal direction while being sequentially wound around the cable fixing device 3a arranged at the one connection end 2a. A cable 6a, one end of which is fastened to a cable fixture 4a disposed at one connecting end 2b, is connected to the cable 5a via a connecting fitting 7a.

Therefore, the connecting ends 2a, 2b of the sheets 1a, 1b are floated or agitated by tides, water currents, waves, etc., and earth and sand enters the lower surfaces of the sheets 1a, 1b, causing the sheets 1a, 1b to be damaged. Push up, seat 1a, 1b, cable fixing device 3a for cables 5a, 5b,
4a and the connecting fittings 7a, etc. were damaged, and the sheet 1
Sheet 1 separated when a and 1b are separated
There were problems such as a and 1b being washed away.

[Purpose of the invention] The purpose of this invention is to solve these problems and provide a sheet connection structure that is easy to install and can effectively perform its functions over a long period of time without coming apart. shall be.

[Structure of the invention] The sheet connection structure of the present invention has a plurality of transparent windows at appropriate intervals in the longitudinal direction on the connecting edge of each sheet, and a cylindrical part through which a cable is inserted through each of the transparent windows. The cables are arranged in parallel so as to face each other, and the portions of the cables exposed through the transparent window are connected to each other by a connector.

[Example] Next, an example of the present invention will be described based on the drawings. FIG. 1 shows an embodiment of the present invention, in which the sheets 1 and 2 connected to each other have a thickness of 2 to 10
It is made of a synthetic resin sheet such as polyvinyl chloride, polyethylene, etc., or canvas having a width of 1 to 3 m and a width of 3 to 10 m, and the sheets 1 and 2 are overlapped at their connecting ends 3 and 4, respectively.

On the upper surface 5 of the upper sheet 1, along the connecting edge 6, there is a cylindrical portion 7 made of a sheet material having approximately the same material and thickness as the sheets 1 and 2.
are installed in the longitudinal direction, and a cylindrical part 9 similar to the cylindrical part 7 is installed in parallel with and adjacent to the cylindrical part 7 on the upper surface 8 of the lower seat 2.

In this embodiment, the cylindrical portions 7 and 9 are attached to the sheet 1.
and 2, and is configured to be fixed using an adhesive, welding, sewing, etc. For example, the connection ends 3 and 4 of the sheets 1 and 2, respectively, may be formed into a folded cylindrical shape. may be configured.

Each of the cylindrical parts 7 and 9 has a plurality of transparent windows 12 and 13, which are elongated and have an appropriate size, extending in the longitudinal direction at the top parts 10 and 11 of the cylindrical parts 7 and 9, so that the windows 12 and 13 are disposed facing each other in the longitudinal direction. They are formed at appropriate intervals.

Further, the cylindrical portions 7 and 9 have cables 14 and 1.
5 is inserted, and the portions of the cables 14 and 15 exposed in the transparent windows 12 and 13 are connected to each other by a connector 16.

To form such a sheet connection structure,
The sheets 1 and 2, in which the cables 14 and 15 have been inserted into the cylindrical parts 7 and 9 in advance, are placed so that the cylindrical parts 7 and 9 are parallel to each other and the transparent windows 12 and 13 are opposite to each other. The cables 14 and 1 are laid in contact with the cables 14 and 1 and are exposed in the transparent windows 12 and 13 of the respective cylindrical parts 7 and 9.
5 need only be connected to each other by means of couplings 16.

According to the seat connection structure constructed in this way, water flow flowing on the upper surface of one seat 1 toward the other seat 2, or waves reciprocating therebetween, are prevented from flowing through one cylindrical portion 7 or the other. One cylindrical part 9 changes the direction upward and presses the cylindrical part 7 or 9, and then generates countless small downward vortices behind the downstream cylindrical part 9 or 7. , which acts to press down the sheet 2 or 1 on the downstream side, thereby preventing the sheet 1 or the sheet from floating or being stirred. For this reason,
This prevents dirt from entering the lower surfaces of both sheets 1 and 2, and since they are connected via a pair of cables 14 and 15 inserted through the cylindrical parts 7 and 9, they are extremely strong and will not be damaged. There is no need to worry about In particular, since the connector 16 does not deviate in position by more than the length of the transparent windows 12 and 13, the cylindrical parts 7 and 9 are connected at a predetermined position. Therefore, there is no gap between the cylindrical parts 7 and 9 due to deviation in the length direction of the connecting position, so there is no fear of damage to the sheets 1, 2, etc. due to the intrusion of earth and sand.

In this embodiment, only some of the connecting portions have been described, but it goes without saying that the same method can be used to connect more sheets to each other in sequence.

Furthermore, FIG. 2 shows an embodiment of a connecting device 16 used in the present invention, and this connecting device 16 connects the inside of the coil portion 17 of the scissor-shaped spring to the cylinder of one of the sheets 2 shown in FIG. 1. Cable 15 inserted into shaped portion 9
, and one working end 1
The insertion portion 2 of the cable 14 is inserted into the cylindrical portion 7 of the other sheet 1 shown in FIG.
0, and further bends its tip in the horizontal direction to form the locking part 22 of the other working end 21. Before use, the cable 15 is inserted into the insertion part 18 in advance. , push down the working part 21a of the working end 21 in the direction of the other working part 19 as shown by arrow A in FIG. 2, release the locking part 22 and the working end 21, (the part indicated by the chain arrow B in FIG. 2), the other cable 14 is inserted into the insertion part 20, and then the working end 2
1, the working end 21 is released again.
and working end 22 are closed, and cables 14 and 15 are closed.
can be connected to each other, and by using this connecting tool 16, the present proposal can be implemented more easily.

[Effects of the invention] The sheet connection structure according to the present invention has a plurality of transparent windows at appropriate intervals in the longitudinal direction on the connection edge of each sheet, and a cylindrical portion through which a cable is inserted is provided in parallel, Since the cable-shaped parts exposed in the transparent windows arranged opposite to each other are connected to each other by the connecting tool, it is sufficient to simply pass the cable-like parts through the cylindrical part and connect them with the connecting tool. The labor required for connection is small and the work can be completed in an extremely short time, and the connected end of the sheet will not float or be stirred up by tides, water currents, waves, etc., so there will be no dirt or sand on the covered surface. Most of the cables are placed in the cylindrical part, so they are highly durable.In addition, the connecting tool only shifts by the length of the transparent window, so it can be connected at a predetermined position. Because of this, there is no bias in the connecting force due to displacement in the length direction of the connectors, and almost equal tensile force is applied to each connector, which prevents the connectors from being damaged and allows them to be arranged parallel to each other. Since there are no gaps between the cylindrical parts, dirt is prevented from entering the lower surface of the sheet between the cylindrical parts. Therefore, it has various effects such as no sheets being washed away due to separation.
