Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting sheet for connecting a large number of sheets to each other to form a wider sheet. The present invention relates to a connection sheet that has no opening.

[0002]

2. Description of the Related Art As a soft ground embedding sheet for civil engineering and a curing sheet for construction, a synthetic long fiber woven fabric sheet is used, but the width of the fabric manufacturing machine is larger than the construction area. In view of its small size and portability, a method of limiting the size of one piece and binding and connecting it at the site of the facility is generally adopted. For this reason, a method of sewing a connecting fabric having a binding hole on the side surface of the fabric and binding the connecting fabrics together is generally adopted. Various methods have been proposed (Japanese Patent Publication No. 61-49416, Japanese Utility Model Publication No. 64).
-30376).

However, in the above-mentioned conventional method, since the sheets are connected only by the bundlings provided at a predetermined interval, the connecting fabric bundling is caused by the pressure from the lower portion and the upper portion applied to the sheet and the connecting fabric in the long term. There is a problem in that the points open in an arc shape, leakage occurs from this opening, and furthermore, the binding section collapses due to concentrated loading on the binding section.
Conventionally, in order to prevent such a problem, a very laborious work has been performed in which the binding interval is reduced and the opening is narrowed, specifically, the binding is performed at an interval of about 5 cm.

Further, since the sludge and the like is prevented from flowing out from the lower surface or the upper surface of the sheet only by connecting the connecting woven fabrics, the sheets are tightly spread so as not to cause a gap between the connecting woven fabrics during binding. Although it is necessary, the sheet is usually as large as several tens of meters × several tens of meters, and it is very difficult to spread the sheet.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, the inventor of the present invention can easily perform on-site construction, and even in the long term, even if an opening is formed in the connecting portion, a sludge or the like leaks. The present invention has been achieved as a result of earnest research on a sheet that does not generate

[0006]

That is, according to the present invention, a plurality of connecting sheets are fixed to both side edges of the upper surface, and tape fasteners are provided on one side edge of the upper surface and the other side edge of the lower surface. A connection sheet, wherein at least the connecting sheet fixed to the upper surface tape fastener side is fixed to the central portion side of the tape fastener.

[0007]

In the connecting sheet of the present invention, the joining of the main body sheet with the tape fastener and the connecting sheet are used together, so that the strength of the connecting portion is improved and the number of connecting means can be reduced as compared with the conventional one. The connection work can be facilitated.

Further, since the connecting sheet is present on the joint portion of the main body sheet and the main body sheet is present below the connecting portion of the joint sheet, even if an opening is formed in the joint portion or the connecting portion, in the former case, In the latter case, the connecting sheet and the main body sheet prevent sludge from leaking. Therefore, at the time of connection at the site, it is not necessary to tightly lay the connection sheets close to each other as in the conventional case, and workability is greatly improved.

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment relating to a connecting sheet of the present invention, and FIG. 2 is a sectional view showing the connected state.
In FIGS. 1 and 2, 1, 1 ′ are body sheets 2, 3, and
3'is a connecting sheet, 4, 5, 5'is a tape fastener, 6 is a connecting means, 7 is a connecting member, 8 is a joining portion, and 9 is a connecting portion.

One side 4 and the other side 5 of the tape fasteners, which are paired with each other, are provided on one upper surface side edge portion and the other lower surface side edge portion on the main body sheet 1. Connection sheet 2,
The positions of the tape fasteners 4 and 5 are appropriately determined depending on the length of 3. Alternatively, the tape fastener may be separately manufactured and attached at an appropriate position by sewing or the like. The width is preferably at least 5 cm or more. 5 cm
If it is less than this, the position may shift or come off during rough operation on site. The wider the width, the better, but the cost is disadvantageous, and about 30 cm is more preferable.

By attaching a tape fastener to the other side edge portion of the main body sheet 1, the connection can be made in the vertical direction.

The connecting sheets 2 and 3 are fabrics or sheets provided with connecting means 6 in advance. At least the connecting sheet 2 fixed to the upper surface tape fastener 4 side is fixed to the central portion side of the tape fastener 4 by sewing or another method. The fixing position of the other connecting sheet 3 is not particularly limited. It goes without saying that the strength of the fixed portion is required as appropriate.

The connecting sheet of the present invention is joined so that the adjacent main body sheets 1, 1'are overlapped with each other. The overlap of the main body sheet joining portion 8 is appropriately determined depending on the strength of the sheets to be used, particularly the connecting sheets 2 and 3, and the connecting interval.
It is preferably 10 cm or more. If the length is less than 10 cm, there is little overlap depending on the work method and sludge leaks. Conversely, if there are many overlaps, the work is difficult and the cost is disadvantageous.
When m, the overlapping portion is preferably 0.8T to 1.5T.

The connecting sheets 2 and 3'are connected by the connecting member 7 without an opening. However, since the main body sheet always exists below the connecting portion 9, there may be some gap.
On the contrary, the connecting sheets 2 and 3 ′ may be overlapped. Therefore, it is not necessary to tightly close the pad during work.

As the connecting means 4 and 5, a conventionally known method such as a connecting hole for binding a rope or a belt fixed in advance to the connecting sheet can be used, and a means which can be easily connected is preferable.
More preferably, the connecting means and the connecting member are located only on the upper surface of the connecting sheet. Specifically, 2 to 4 rope-shaped wire rods are woven in a side edge portion of the connecting sheet at predetermined intervals in the longitudinal direction and with a margin. In this case, since the connecting means is located only on the upper surface of the sheet and the connecting member does not cause a gap in the overlapping portion of the main body sheet and the connecting sheet, the sheets increase shear stress between the sheets, and sludge and the like are generated. Will be prevented from invading the connection part. Further, the connecting means can be expanded at the time of connection, and the connecting work is very easy.

FIG. 3 is a sectional view showing a connection state of another embodiment of the connection sheet of the present invention. As shown in FIG.
Connect the connecting means 7 of the one connecting sheet 3'to the main body sheet 1 '
Since the joint portion 8 and the connecting portion 9 do not overlap by being provided outside the side edge portion of, when either one of them is destroyed,
It is preferable since leakage from the other side can be prevented more effectively.

The following is an example of an experiment conducted to confirm the effect of the present invention.

As the main body sheet, polyester woven cloth 2
20m × 50, which was sewn on a sewing machine by overlapping a 5cm width by 5cm.
m sheets were used. The overlapping part of the body sheet is 20
It was laid on ultra-soft ground so that people could not walk due to sludge, and tied with 8 mmφ synthetic fiber rope at 15 cm intervals. Even if sand was sprinkled on top of it, embankment work could be performed without opening sludge between the binding parts and spouting sludge, and without breaking the binding rope.

[0020]

As described above, according to the connection sheet of the present invention, the tensile strength is increased by the strength of the connecting portion and the strength of the tape fastener to prevent the connecting portion from being broken and the connecting means such as connecting means. It is not necessary to increase the number of sheets more than necessary, and even if a part is destroyed, it is possible to prevent watery fluid such as sludge from penetrating into the upper part and the lower part, and it is required when paving on site. Tightness is eased and workability is excellent.
