Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a sheet that is employed when a large number of sheets are joined together to form a curing sheet, a civil engineering sheet, a silt protector, an outdoor tent, etc. This invention relates to a connecting fabric.

(Prior Art) Conventionally, when forming this type of curing sheet, civil engineering sheet, outdoor tent, etc., a structure as shown in FIG. 3 has been adopted. In this conventional joining structure, first, the edge of the sheet 11 is bent so as to accommodate the reinforcing rope 12 therein, and then the reinforcing rope 12 is inserted into the sheet 11 itself by sewing 13 or the like. Fix it. This reinforcing rope 12
is for reinforcing the connecting edges when connecting the sheets 11. Then, a large number of holes 14 to 14 are made in a portion of the sheet 11 close to the reinforcing rope 12, each of these holes 14 is reinforced with eyelets, and connecting ropes 15 to 14, which are connecting members, are inserted into each of these holes 14. 15, a pair of adjacent sheets 11, 11 were joined. By repeating this joining structure between adjacent sheets 11, large tents and the like were also formed.

However, in such a joint structure, the reinforcing rope 12 and eyelet members are always required, and these must be attached or processed at the work site, which means that the silt protector is stretched and the tent is The construction of such facilities has become very laborious and time consuming.

(Problems to be Solved by the Invention) The present invention has been made in order to deal with the above-mentioned problems, and the purpose of the present invention is to solve the above-mentioned reinforcing ropes 12 and The objective is to eliminate the need for eyelet members and to make it extremely easy to join sheets at the work site.The fabric for connecting sheets according to the present invention solves this problem. be.

(Structure of the Invention) The structure of the present invention, which specifically solves the above-mentioned problems, is a belt-shaped woven fabric made of stretch-resistant synthetic fibers, which is joined to the edges of each pair of sheets to connect them to each other. A plurality of floating tissue portions are formed along the edge of this belt-like fabric by partially omitting the warp and weft yarns that make up the fabric, and each of these floating fabric portions is This is a fabric for connecting sheets, characterized in that a connecting member can be inserted through the sheet.

By adopting the above configuration of the present invention, the joining means used for joining sheets can be configured extremely easily, and the work of joining sheets can be simplified. .

(Means for Solving the Problem) FIG. 1 is a perspective view showing a state in which a pair of sheets 21, 21 are connected to each other by a sheet connecting fabric 30 according to the present invention. This sheet 2
1 is made of a synthetic fiber woven fabric coated with a resin and has a predetermined flexibility. A sheet connecting fabric 30, which is a belt-shaped fabric made of synthetic fibers, is fixed to the side edge of the sheet 21 by sewing or high-frequency welding.

Along the edge of the sheet connecting fabric 30 (the edge on the side where the sheet connecting fabrics 30 in FIG. 1 are in contact with each other), a large number of floating tissue portions 31 are arranged in rows at predetermined intervals. It is formed like this. As shown in the cross-sectional view of FIG.
and weft threads 33 are partially omitted. In other words, in this floating structure portion 31, each warp yarn 3
2 and weft yarns 33 are not knitted alternately, but are formed so that the warp yarns 32 or weft yarns 33 are at the center and the weft yarns 33 or warp yarns 32 are positioned above and below them. Further, in this embodiment, the size of the floating tissue portion 31 is set so that the vertical and horizontal lengths are each 15 mm x 4 mm. However, this floating tissue portion 31
The size is not limited to this. It may be implemented with appropriate changes depending on the size of the connecting member 40, which will be described later. It should be noted that constructing the sheet connecting fabric 30 having such a floating tissue portion 31 can be easily performed using a loom equipped with a dobby mechanism.

The sheet connecting fabric 30 has a structure as shown in FIG. 2 as a whole. Second
In the figure, reference numeral 32a indicates a core yarn, 32b an outer fabric yarn, 32c a lining yarn, 32d a binding yarn, and 33 a weft yarn, that is, a weft yarn. FIG. 4 is a tissue diagram of this sheet connecting fabric 30, and for easy understanding, the outer fabric yarn 3
2b and the joining thread 32d are schematically shown.

The sheet connecting fabric 30 of this embodiment also has the following features.

In order to provide strength in the width direction of the fabric 30,
The weave structure has a large number of weft threads.

Even if the warp density is relatively low, it has a woven structure that does not cause misalignment on the gray fabric.

In order to increase the strength of the fabric 30 located near the floating tissue portion 31, core yarns 32 are provided in the upper and lower portions in the width direction.
It contains a.

(Example) Specifically, the sheet connecting fabric 30 has the following configuration.

Thickness 1.5mm Width 100mm, irregular double work, Material Tetron warp 1260D-108F 281 warp binding threads 1260D-108F 136 warp core threads 1260D-108F 20 weft threads 750D- 72F/2 48 threads/30mm width Directional strength: 27 Kgf/cm In this embodiment, the sheet connecting fabric 30 was constructed using an irregular double weave, but it may also be constructed using a plain weave as shown in FIG.

(Function) Next, a method of joining the sheets 21 to each other using the sheet connecting fabric 30 and each of its floating tissue portions 31 will be explained. First, the sheets 21 having a predetermined size are arranged at appropriate positions, and the sheet connecting fabrics 30 are fixed to their mutually adjacent edges by sewing or high-frequency welding. Then, the connecting member 40 made of a flexible wire material such as a string formed by twisting fibers is inserted alternately between, for example, the floating tissue portion 31 on one sheet 21 side and the floating tissue portion 31 on the other sheet 21 side. By this, both adjacent sheet connecting fabrics 30 are connected. Thereby, each sheet 21 is joined, that is, connected. Of course,
As the connecting member 40 used in this case, other flexible members such as a wire covered with vinyl or the like, or a plastic connecting member may be used instead of the above-mentioned string.

In the above example, a case has been described in which on-site alignment, that is, joining of the sheets 21 is performed at a work site, but this method is not necessarily required. In other words, if the situation at the joining site of the sheet 21 is clear in advance, a large number of floating structure parts 31 are assembled at a factory etc. according to the size, length, joining position, etc. of the sheet 21.
Each sheet connecting fabric 30 formed with
The sheet 21 formed in this way
All you have to do is transport it to the site and do the joining work. This applies not only to the formation of curing sheets and outdoor tents, but also to civil engineering sheets, silt protectors, and the like.

(Effects of the Invention) The sheet connecting fabric 30 according to the present invention configured as described above is extremely simple because each floating structure portion 31 simply changes the configuration of the warp yarns 32 and weft yarns 33 that constitute the sheet connecting fabric 30. It can be formed into Further, by using this sheet connecting fabric 30, the work of joining the sheets 21 can be performed extremely easily. That is, since each sheet connecting fabric 30 is made of a stretch-resistant synthetic resin material, it can be very easily fixed to the sheet 21 by melting it using high frequency waves or the like. A connecting member 4 is provided within each floating tissue portion 31.
0, each warp thread 32 and weft thread 33
Since they are not woven, they are loose with respect to each other, so that they can be easily inserted into each floating tissue portion 31. In other words, it is sufficient to force the connecting member 40 into the floating tissue portion 31 by pushing aside each warp yarn 32 and weft yarn 33 with the tip of the connecting member 40 to be inserted. The connection member 40 can be easily inserted into the interior.

In the case of the sheet connecting fabric 30 in which the connecting member 40 is inserted through the connecting member 40, the warp yarns 32 and the weft yarns 33 are shifted in position due to the insertion of the connecting member 40, but they do not break as in the case of conventional eyelet processing. Therefore, the strength of the sheet connecting fabric 30 does not deteriorate. Therefore, this sheet connecting fabric 30 is
Not only does it not require any eyelet processing, which was required in the past, it also has a clear advantage in that there is no deterioration in strength.

(Summary) As described in detail above, in the present invention, as exemplified in the above embodiment, a large number of floating tissue portions 31 are arranged at predetermined intervals on a sheet connecting fabric 30 made of stretch-resistant synthetic fibers. The sheet connecting fabric 30 is then formed into a row with the sheet 2.
This sheet connecting fabric 30 is fixed to the edge of 1.
Since the pair of sheets 21 with attached sheets 21 can be connected by sequentially inserting flexible wires such as the connecting member 40 into each floating tissue portion 31 of the sheet connecting fabric 31, the present invention is advantageous. If such a sheet connecting fabric is used, it is possible to omit reinforcing ropes and eyelet members, which are very time-consuming to attach or process, and the work of joining the sheets can be performed extremely easily.
