Description

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

(Prior Art) Conventionally, when forming this type of curing sheet, civil engineering sheet, outdoor tent, etc., a structure as shown in FIG. 5 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 15 are inserted into each of these holes 14. A pair of mutually adjacent sheets 11, 11 were joined together by. Each sheet 11 adjacent to each other has such a joining structure.
By repeating this process in between, even large tents were formed.

However, in such a joining structure, reinforcing ropes 12 and eyelet members are always required, and these must be attached or processed at the work site. This is because sheets for outdoor tents and the like are usually manufactured and transported in a rolled state, but if there is a reinforcing rope 12 on one edge of the sheet, this will get in the way, making it impossible to roll the sheet into a roll. This is because it is extremely difficult. As described above, it has become very labor-intensive and time-consuming to carry out work on-site when setting up silt protectors, constructing tents, etc.

(Problems to be Solved by the Invention) The present invention has been made to address the above-mentioned problems, and its purpose is to solve the above-mentioned reinforcing rope 12, which requires a lot of effort to attach or process. The object of the present invention is to eliminate the need for installation work and to make it extremely easy to join the 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 solved the above-mentioned problems is that a belt-shaped fabric made of stretch-resistant synthetic fibers is joined to the edges of each pair of sheets to connect them to each other. forming a hollow weave portion located at one edge of the belt-like fabric;
In addition to simultaneously weaving the flexible core material into the hollow weave portion, a plurality of holes for inserting the connecting member are formed in a portion of the belt-like fabric adjacent to the hollow weave portion. This is a fabric for connecting sheets, which is characterized by the following:

By adopting the above configuration of the present invention, the joining means used for joining sheets can be constructed extremely simply, and the joining action of the 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.

A hollow weave portion 31 is formed 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). As shown in the enlarged cross-sectional views of FIGS. 1 and 3, inside the core material 32
is included. As shown in FIG. 2, the sheet connecting fabric 30 is mostly formed by irregular double weaving, and the front and back two layers of fabric are tied together with a binding thread 34.
They are connected by d. On the other hand, the hollow weave portion 31, as shown in FIG.
The above-mentioned two-layered fabric is simply made into a bag without binding with the binding thread 34d, and a core material 32, which is a substitute for the conventional reinforcing rope 12, is woven into the bag. This is what I did.

Further, in the case of the embodiment shown in the drawings, the size of the hollow weave portion 31 is set so that the horizontal length and thickness are 12 mm x 3 mm when the core material 32 is included. However, the size of the hollow weave portion 31 is not limited to this.

In this way, the core material 32 as a reinforcing material in place of the conventional reinforcing rope is applied to the bag weave section 3 on the loom.
1 and woven at the same time to form a sheet connecting fabric 30. It should be noted that weaving the sheet connecting fabric 30 having such a hollow weave portion 31 can be easily performed using a normal loom. A large number of holes 36 are formed in adjacent portions. These holes 36 are easily formed by melting the sheet connecting fabric 30 by heat or high frequency melting. In addition, each hole 3
6 need not be completely opened as shown in FIG. 1, but may be implemented simply as a +- or --shaped slit.

2 and 3 show the structure of the main part of the sheet connecting fabric 30, and in each figure, reference numeral 3
4a is a core yarn, 34b is a facing yarn, 34c is a lining yarn, 34d is a binding yarn, 33 is a weft yarn,
That is, each weft thread is shown. Further, FIG. 4 shows a tissue diagram of the sheet connecting fabric 30 for reference.

The sheet connecting fabric 30 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.

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

Thickness 1.5mm Width 100mm, irregular double weave, Material Tetron warp yarn 1000D-72F 281 pieces Warp binding yarn 1000D-72F 124 pieces Warp core yarn 1500D-108F/4 24 pieces Weft 750D- 72F2 40 pieces /30 mm Further, the core material 32 is formed by weaving a total of 96 Tetoron yarns (1500D), which are the same material as the warp yarns 34b, 34c and the binding yarns 34d.

(Function) Next, a method of joining each sheet 21 to each other using this sheet connecting fabric 30 and its holes 36 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. A connecting member 4 made of a flexible wire material such as a string formed by twisting fibers
0, for example, alternately through the holes 36 on one sheet 21 side and the holes 36 on the other sheet 21 side, so that both adjacent sheets connecting fabric 3
Concatenate 0. Thereby, each sheet 21 is joined, that is, connected. Of course, as the connecting member 40 used in this case, other flexible wire material, such as a wire covered with vinyl or the like, a synthetic resin connecting member, etc. 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 has been clarified in advance, the part close to the hollow weave part 31 will be installed at the factory etc. according to the size, length, joining position, etc. of the sheet 21. Each sheet connecting fabric 30 having a large number of holes 36 formed therein may be fixed to the sheet 21, and the sheets 21 thus formed may be transported to the site and the joining work may be performed as is. This means that
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 the bag weave portion 31 simply changes the weaving of the warp yarns 34 and weft yarns 33 that constitute the sheet connecting fabric 30. It can be formed into

In addition, even if the sheet connecting fabric 30 has a bag weave portion 31 at its edge that is different in thickness from other portions (thick), the width thereof is narrower than the width of the sheet. By winding it up in a state slightly inclined to the winding roll, it is possible to form it in advance in large quantities in a factory or the like and wind it up.

Furthermore, if this sheet connecting fabric 30 is used, 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. And each hole 3
The connecting member 40 may be inserted into the connecting member 6 and the connecting members 40 may be bound together. In this case, each hole 36 is formed by forming an edge of the sheet connecting fabric 30 between the hollow weave portion 31 and the core material 3.
2, the connecting members 40 can be formed as close to the core material 32 as possible, and the connecting members 40 can be inserted into these holes 36 extremely easily.

In the case of the sheet connecting fabric 30 in which the connecting member 40 is inserted, the warp threads 3 constituting the sheet connecting fabric 30 are
2 and weft 33 are made of stretch-resistant synthetic fibers, and the edges of the sheet connecting fabric 30 are reinforced by the hollow weave portion 31 and the core material 32, so that the connecting member 40 can be held securely. be able to. Therefore, the work of attaching the reinforcing rope 12, which was conventionally required, is not required at all.

(Summary) As detailed above, in the present invention, as exemplified in the above embodiment, in order to connect a pair of sheets to each other, a belt made of stretch-resistant synthetic fibers is attached to the edge of each of these sheets. A belt-like woven fabric, in which the formation of a bag weave portion located at one edge of the belt-like woven fabric and the wrapping of a flexible core material within the bag weave portion are performed by simultaneous weaving. In addition, it is characterized by forming a plurality of holes for inserting the connecting member in the belt-like fabric portion adjacent to the hollow weave portion, and thereby,
The process of attaching the reinforcing rope 12, which is very time-consuming to attach or process, can be made unnecessary, and the work of joining the sheets can be carried out extremely easily at the work site. A sheet connecting fabric can be provided.
