Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to an improvement of a woven belt which is sewn to the periphery of a soft ground burying sheet for civil engineering or a curing sheet for construction and used for reinforcement and joint.

[0002]

[Prior Art]

 Conventionally, this type of woven belt has a certain interval along the longitudinal direction of the woven belt, such as those proposed as a fixing belt for civil engineering sheets in Japanese Examined Patent Publication No. Sho 62-15683 and No. Sho 62-14185. For example, some were woven to form a number of horizontally long holes. In addition, there are also ones in which a large number of vertically elongated holes are formed by fusing with a hot knife along the longitudinal direction of the woven belt and at predetermined intervals.

However, the former one has a slow weaving speed due to a complicated weaving method and is inferior in productivity, and the lateral oblong hole portion is weak against the tensile force in the belt width direction. However, the belt itself was coarsely woven and the belt itself was soft and unsatisfactory in strength. The latter one has a drawback that the strength of the belt is greatly reduced because the warp is cut.

Therefore, the inventor of the present invention has proposed a woven belt for joins, which solves the above-mentioned problems, by Japanese Utility Model Laid-Open No. 1-177285. The structure is a structure in which one or a plurality of thick cords are alternately formed with a weaving portion and an exposed portion at predetermined intervals along the longitudinal direction of the woven belt. Since this woven belt for joints such as sheets has high strength, it has a feature that it can be suitably used as a reinforcement and joint for a soft ground buried sheet for civil engineering and a curing sheet for construction. However, in addition to the warp, a thick cord and its supply device must be prepared, and since the thick cord is not fixed to the woven fabric, there is a disadvantage in that a strong tensile force extends to form an unbalanced joint.

[0005]

[Problems to be solved by the device]

 The present invention was developed with the object of solving the above-mentioned drawbacks of the conventional products and proposing a structure for easily forming a strong joint by simply weaving warps and wefts that are the same as or similar to the woven surface. Is.

[0006]

[Means for Solving the Problems]

 In the present invention, the above problem is solved as a joint structure such as a sheet in which the woven portion 5a and the non-woven portion 5b of the warp 2 are alternately formed at a predetermined interval in the ear portion 1 of the woven fabric. A preferred embodiment of this structure is such that the selvage 1 comprises a weaving part 5a of weft 3 and warp 2 continuous from the woven surface of the woven fabric, and a non-woven part 5b of only the warp 2, or the selvage 1 is woven. The weave part 5a of the multiple weave by the weft thread 3 and the entanglement thread 4 to the warp thread 2 which are continuous from the cloth surface of the cloth, and the woven selvage portion 5c and the warp thread of the part of the warp thread 2 of the selvage part having the same structure as the weave surface The rest is the non-woven part 5b.

[0007]

[Action]

 In such a structure, the weaving 3 is partially woven in the weaving direction with respect to the warp 2 to make it non-woven, or a part of the warp 2 woven in the multiple weave is made non-woven. The joint can form a jointable portion on the ear. Since the tufts of warp yarns of the non-woven part are alternately present with the woven part of the multi-woven part, there is no movement of the warp yarns in the joint part, a uniform force is applied to the joint part, and the overall strength is increased.

【Example】

 FIG. 1 is an organization chart showing a first embodiment of the present invention. The cross section is shown in FIG. In this example, the woven portion 5a of the warp yarn 2 and the weft yarn 3 is provided on the ear portion 1 of the plain weave narrow fabric, and the non-woven portion 5b for letting the weft yarn 3 escape from the ear portion and leaving the warp yarn 2 at a predetermined interval. Are formed alternately. As shown in FIG. 2B, the non-woven portion 5b has nothing on the back surface and only the warp 2 is exposed. That is, in order to have such a structure, the non-woven portion 5b which is in a non-woven state is formed by not weaving all of the weft yarns 3 continuous from the woven surface of the normal weaving structure.

FIG. 3 is an organization chart showing the second embodiment. In this example as well, the selvage 1 is made up of a woven part 5a and a non-woven part 5b, but the woven part 5a is a multi-woven weave composed of weft yarns 3 continuous from the woven surface of the woven fabric and entangled yarns 4 to the warp yarns 2. In the non-woven part 5b, a part of the warp yarn 2 of the selvage part forms the weave selvage part 5c of the same structure as the weave surface, and the rest of the warp forms the non-woven part 5b. That is, as shown in FIGS. 4 (b) and (c), the non-woven portion 5b is present on the selvage selvage portion 5c which is formed in the same manner as the other weaving surface by incorporating the weft. ing. The above embodiment is for a narrow woven fabric, that is, a woven belt, and such a woven belt is sewn to the periphery of a sheet or the like and used for a joint, but the ears of the woven sheet itself are formed. You may contact the seats directly.

[0010]

[Effect of the device]

 As described above, according to the present invention, since the joint portion is formed only by forming the woven portion and the non-woven portion, the productivity is good, and the non-woven portion is continuous with other woven portions. Therefore, the strength is great and the joint function is sufficiently fulfilled.
