Abstract

(57) [Summary] [Purpose] A synthetic resin sheet used for agriculture, civil engineering, construction, etc. has a structure that can be easily attached and fixed as a single unit and uses a special processing method. It is intended to be provided inexpensively. [Structure] A synthetic resin sheet is provided with a rope internally provided for reinforcement at an outer peripheral edge portion formed by folding back or edge tape.
The sheet can be used as an attachment rope by fixing it as a sheet member by sewing or the like while pulling out an appropriate length from the four corners of the sheet.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to synthetic resin sheets for agricultural, civil engineering, construction, or covering materials and open sheets.

[0002]

[Prior art]

 Conventionally, Nozumi sheets, curing sheets, rejuvenating sheets, etc. are made by slitting a synthetic resin film into a narrow width and stretching the tape yarn obtained by stretching the film. A material obtained by weaving and coating a resin of the same type as the tape yarn on one or both sides using this as a base material is used. These synthetic resin sheets are generally reinforced by folding the outer peripheral edge portion by sewing or welding, and providing a plurality of eyelets at predetermined intervals on the folded edge. When attaching and fixing the sheet, the formed eyelet is generally used, and it is generally tied to the support using a braid or a wire, or is piled through the eyelet.

[0003]

[Problems to be solved by the device]

 The mesh sheet for scattering and falling that is stretched over the scaffolding at the construction site is also required to have eyelet processing on the outer peripheral edge, and from the viewpoint of safety, it is necessary to adequately fix the support such as pipes at multiple points. However, since the mesh sheet is large, about 1.8 x 5.1 m, and it is generally stretched on a vertical surface, there is a need for a fixture that can be temporarily fixed. It has also been done (eg Jitsukō Sho 49-36424). However, the work with the fixtures is inefficient, and it is desirable that the seat itself has some sort of fixture, and the simplest method is to sell the eyelet of the sheet by attaching a braid for attachment to the eyelet. Though it was thought, the process is not done by commercialization because it requires manual work and mechanization requires a huge investment, resulting in cost increase.

[0004]

[Means for Solving the Problems] As a result of various studies on effective structures for solving these problems, a synthetic resin sheet with a mounting rope according to the present invention was obtained. The structure is characterized in that, in a synthetic resin sheet having a reinforcing rope in its outer peripheral portion, the end portions of the reinforcing rope are pulled out from four corners to appropriate lengths and fixed. Is.

[0005] Many synthetic resin sheets having an eyelet processing on the outer peripheral edge have a rope internally for reinforcement against a force in the external direction. -It is used for mounting by fixing the end of the rope, which is cut according to the size of the harness, to the outside with an appropriate length.

[0006]

[Action]

 In the present invention, the reinforcing rope, which has been conventionally incorporated into the structure as a component, is used for the mounting rope with a slight modification of the working process, so the equipment investment is small. Since it can be manufactured without significantly increasing the material cost and the manufactured sheet can be easily installed without preparing another item, it is effective when used in various places and situations. It has a simple structure.

[0007]

【Example】

 Hereinafter, the description will be added based on the manufacturing process in Examples.

Example 1 A film made of high-density polyethylene was slit and stretched 4.5 times to obtain a 900 den tape yarn. Using this as a warp and weft, weaving 8 × 10 yarns / inch into a base material, melt extruding low-density polyethylene and laminating it on both sides with a thickness of 25 μm Obtained.

While unwinding the raw fabric 1 and inserting a braid 3 of high-density polyethylene fiber having a diameter of about 5 mm, the widthwise both edges are folded back by about 5 cm and welded by a welder, and the folded portion 2 has an eyelet at an interval of about 90 cm. 4 was cut and cut to a length of 370 cm. This state is shown in plan view in FIG.

Next, the both ends in the lengthwise direction are drawn out and folded, and while inserting the braid 3, both ends are folded back by about 5 cm, welded by a welder, and the eyelet 4 is struck on the folded portion 2. It was The braid 3 inserted here was pulled out by 30 cm on both sides so that it could be used as a rope for attachment, and it was sewn and fixed in three places with a manual sewing machine. FIG. 2 is a plan view of the completed seat with attachment rope according to the first embodiment.

Example 2 The same process as in Example 1 was performed using the same process, but the four corners of the process were cut into rectangular shapes. Similar to the first embodiment, FIG. 3 shows a processed state of both edge portions in the width direction, and FIG. 4 shows a completed state in a plan view. As a result, two ropes were inserted at the four corners of the sheet, which were inserted at the edges in both the width and length directions.

Although this embodiment is based on a curing sheet, it goes without saying that it can be used for a sheet for various purposes. The one having two mounting ropes shown in the second embodiment is a large one such as a mesh sheet used for a side wall of a construction site, and is temporarily used when it is stretched on a vertical surface. It was useful because it was easy to install.

[0012]

[Effect of device]

 In the present invention, the rope which has been conventionally provided for reinforcing the edge portion is pulled out to the outside by an appropriate length, and the rope for attachment is provided at four corners of the outer peripheral edge of the synthetic resin sheet. Since it is a different product, the manufacturing process is not much different from the conventional product, and the material cost is only slightly increased. Since the mesh sheet using the structure of the present invention can be used as a temporary fixing at the construction site when it is stretched, work efficiency is good, and it is not necessary to carry other members, so it is also useful from a safety point such as work at high places. For Nozomi seats, by fixing the mounting rope directly to the material, etc., or by tying the mounting ropes together after covering, it is possible to prevent the sheets from scattering due to the wind, and the leisure sheet. Is used as a awning tent that is fixed at the time of laying or using a prop, or as a rain cap when an accident occurs by passing the human head through the opening formed by connecting the mounting rope in one direction. be able to. In other words, it is a synthetic resin sheet that has added functionality for various purposes, but depending on the limited application, a special mounting tool may be attached to the end of the mounting rope, etc. It can be used very effectively as a manufacturing sheet.
