Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention is a method of manufacturing curing sheets, civil engineering sheets, silt protectors, etc. by joining a large number of sheets to each other.
The present invention relates to a fabric for connecting sheets that is used when forming an outdoor tent or the like.

(Prior Art) Conventionally, when forming this type of curing sheet, civil engineering sheet, outdoor tent, etc., a structure as shown in FIG. 4 has been adopted. In this conventional joining structure, first, the edge of the sheet 40 is bent so as to accommodate the reinforcing rope 41 therein, and then the reinforcing rope 41 is attached within the sheet 40 itself by sewing 42 or the like. stick. This reinforcing rope 41
is for reinforcing the connecting edges when connecting the sheets 40. Then, a large number of holes 43 to 43 are made in the portion of the sheet 40 that approaches the reinforcing rope 41, each of these holes 43 is reinforced with eyelets, and connecting ropes 44 to 44 are inserted into each of these holes 43. A pair of mutually adjacent sheets 40 to 40 were joined together. By repeating such joining between adjacent sheets 40, large tents and the like were also formed.

However, in such a joining structure, reinforcing ropes 41 and eyelet members are always required, and these must be attached or processed at the work site. This is due to the following reason. That is, the sheet 40 usually has a large area to constitute a tent or the like, and when it is manufactured in a factory or the like and transported or stored, it is usually wound into a roll. In order to efficiently wind the sheet 40 into a roll, it is necessary that the sheet 40 be completely flat, but if the reinforcing rope 41 and eyelets as described above are present only in one part, this winding will be difficult. It's bound to go wrong. Therefore, it is desirable that the reinforcing rope 41 be attached and the eyelets be worked on-site. The above-mentioned process has become extremely time-consuming and labor-intensive when setting up silt protectors and constructing tents.

(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 41 and It is an object of the present invention to eliminate the need for eyelet members and to enable the work of joining the sheets 40 to be performed extremely easily.
It is.

(Means for Solving the Problems) The configuration of the present invention that specifically solves the above problems is listed below.

The present invention is a belt-like fabric made of stretch-resistant synthetic fibers that is joined to the edges of a pair of sheets 10 to connect them to each other. A method for connecting sheets, characterized in that one of the warp yarns located in the woven fabric is made of a strong flexible wire material, and the flexible wire material is woven so as to appear alternately at a predetermined interval on the front and back sides of the fabric. This is a fabric 20.

FIG. 1 shows a sheet connecting fabric 2 according to the present invention.
A perspective view showing a state in which a pair of sheets 10 are connected to each other by 0 is shown. This sheet 10
is made of a resin-coated synthetic fiber woven fabric and has a predetermined flexibility. A sheet connecting fabric 20, which is a belt-shaped fabric made of synthetic fibers, is fixed to the side edge of the sheet 10 by sewing or high-frequency welding.

The main body of the connecting fabric (hereinafter simply referred to as fabric) 20 of this sheet 10 is a normal plain weave, twill weave, various double weaves, or a combination of these fabrics. One or more of the strong flexible wires 23 thus obtained are woven in the following manner.

That is, in this weaving method, a dobby machine is used during weaving by a loom, and healds that perform shedding motion are provided independently for the flexible wire material 23, separately from the heald group that creates the woven structure of the main body. Then, the opening movement of the heald through which the flexible wire 23 is passed is stopped at the upper or lower end while the main body is woven to an arbitrary length, and is reversed at an arbitrary point. By doing this at predetermined intervals, the fabric is woven as shown in FIG. 2, for example.

In FIG. 2, reference numeral 23a indicates a portion formed as a result of performing the above-mentioned upper stop/reversal and lower end stop/reversal at relatively short intervals, and reference numeral 23b indicates a portion formed by making the upper stop stop relatively long. This is the loop portion formed as a result of flipping it over. This loop portion 23b has a length sufficient to allow a connecting member 30, which will be described later, to be inserted therethrough. Of course, in this case, the portion 23a may be omitted and a loop portion similar to the loop portion 23b may be formed on the lower surface of the main body.

Further, the connecting member 30 used when joining each fabric 20 to each other is integrally molded from synthetic resin, and a tail portion 32 is inserted into a hole 31 in the head part to form a ring. Fixation is achieved by locking the locking portions 34 formed in the hole 31 with a plurality of locking portions 33 formed in the hole 31 . Of course, the connecting member 30 may be replaced with another flexible wire 23, such as a simple string or a wire covered with vinyl or the like.

(Example) The sheet connecting member 20 specifically has the following configuration.

Thickness 1.5mm, width 100mm, plain weave base, material
Tetron Warp thread 1500D-108F2 141 pieces Weft thread 1000D-72F2 22 pieces/30mm Warp cord 1000D-72F/5/3 1 piece In this example, the warp cord is the flexible wire 23, Using Tetron, 1000D−
Five 72F threads were pre-twisted, and three of them were pre-twisted to form a cord with a total of 15 threads. Also,
In weaving the portion 23a of the flexible wire 23, the shedding movement was stopped at the upper position while 18 weft threads of the base fabric were being inserted, and then reversed downward. As a result, the length of each portion 23a is approximately 25 mm.
On the other hand, the loop portion 23b of the flexible wire 23 was obtained by repeating the process of reversing once every four weft threads five times. The length of each loop portion 23b thus obtained was approximately 27 mm.

(Function) Next, a method of joining each sheet 10 to each other using this sheet connecting fabric 20 and its flexible wire 23 will be explained. First, the sheets 10 having a predetermined size are arranged at appropriate positions, and the sheet connecting fabrics 20 are fixed to their mutually adjacent edges by sewing or high-frequency welding. Then, the connecting member 30 is connected to the loop portion 23b on one sheet 10 side and the loop portion 23b on the other sheet 10 side, for example.
By inserting the sheets alternately, both adjacent sheet connecting fabrics 20 are connected. Thereby, each sheet 10 is joined, that is, connected.

In the above example, a case has been described in which on-site alignment, that is, joining of the sheets 10 is performed at a work site, but this method does not necessarily have to be used. In other words, if the situation at the joining site of the sheets 10 is known in advance, each sheet connecting fabric 20 is fixed to the sheet 10 according to the size, length, joining position, etc. of the sheet 10. Then, the sheet 10 thus formed can be transported to the site and the joining work can be performed as is. 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) In the sheet connecting fabric 20 according to the present invention configured as described above, each loop 23b has one of the warp threads 21 constituting the sheet connecting fabric 20 as a strong flexible wire material 23, and , can be formed extremely easily by simply changing the weave.

In addition, when inserting the connecting member 30 into each loop 23, each loop 23b provided on the textile 20 is in a state floating from the textile 20 and has a certain length with sufficient margin. Therefore, the connecting member 30 can be easily inserted into each loop 23b.

Furthermore, since each sheet-connecting fabric 20 is made of a stretch-resistant synthetic fiber material, it can be very easily fixed to the sheet 10 by melting it using high frequency waves or the like.

Furthermore, since the fabric 20 is formed by integrally weaving the flexible wire 23 into one end thereof, the fabric 20 can be made substantially planar as a whole. Therefore, this fabric 20 can be wound into a roll. As a result, when the sheet 10 is woven, the textile 20 may also be integrally woven at the same time, and in this case, the integral sheet 10 and textile 20 may be wound into a roll. can.

In this way, in the fabric 20 through which the connecting member 30 is inserted, the warp yarns 21 and the weft yarns 22 constituting the fabric are made of elongation-resistant synthetic fibers, and have a structure as shown in the drawing of FIG. By doing so, it goes without saying that parts other than each loop 24 will not be cut or the woven structure will not collapse.
Even if the connecting member 30 is attached to a portion located near the zero loop 23b, the connecting member 30 can be held securely.

Therefore, if the sheets 10 are joined using the fabric 20 according to the present invention, there is no need for reinforcing ropes or eyelets that were conventionally required, and the sheets 10 can be easily joined. .
