[Industrial applications]

 The present invention relates to a sheet material to be used as a toy for a greenhouse for agricultural crops, in particular, a multi-story house, which is continuously installed in the valleys of each house of the multi-story house to efficiently drain rainfall.

[0002]

[Prior Art]

 In recent years, farm crops are very often cultivated in greenhouses, but the cultivation facilities for this greenhouse are from small tunnels to small single-story houses, multi-story houses, and even large multi-story houses. And that form has changed drastically. Among these houses, in multi-story and large-scale multi-story houses, toys for drainage are usually installed in the valleys because rainwater flows into the valleys of each house.

Conventionally, a galvanized iron plate has been used as a drainage toy of this type, so that it took a lot of time to construct the galvanized iron plate.

In order to solve these problems, the present applicant has already disclosed in Japanese Utility Model Publication No. 60-38355, Japanese Utility Model Publication No. 62-30921, etc., and as shown in FIG. There is a house 30 in which a sheet material 34 is laid and installed so as to have a substantially U-shaped cross section between the valleys 32.

[0005]

[Problems to be solved by the device]

 However, as described above, when laying a toy sheet material in a multi-story house, a metal pedestal is used for the work above the valley between the houses and for the construction of the toy sheet material. In many cases, a toy sheet material is deployed on top of this, and in this case, the metal pedestal becomes hot during the daytime, and the toy material laid on it is There was a problem that the toys could not perform their original functions due to fusion or the deterioration of ultraviolet rays due to sunlight, especially on the flat surface (valley).

In view of these problems, the present invention reflects the sunlight and prevents the deterioration and damage of the sheet member in the portion corresponding to the metal pedestal portion. The purpose is to provide a sheet material for a.

[0007]

[Means for Solving the Problems]

 The present invention has been devised in view of the problems and objects of the above-mentioned prior art. The gist of the present invention is that the cross section of the multi-story house is continuous in the valleys of the houses and the cross section is approximately U. A toy sheet material for a multi-story house, which is laid and installed to have a shape, characterized in that a reflective layer is formed in the longitudinal direction of the base material sheet. is there.

Further, the present invention is a sheet material for a toy of a multi-story house, wherein the reflection layer is a metal vapor deposition layer.

Further, the present invention is a toy sheet material for a multi-story house, wherein the reflective layer is embedded in a sheet base material.

[0010]

【Example】

 Hereinafter, the seat material for a toy of the multi-story house of the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a sheet material of the present invention. In the figure, 1 indicates the sheet material of the present invention as a whole, and sheet material 1 is an ethylene-vinyl acetate copolymer (hereinafter, simply “EVA”). Is abbreviated) and a reflection layer 3 formed so as to be integrally embedded in a substantially central portion in the longitudinal direction of the sheet base material 2.

Specifically, as shown in FIG. 2, the reflective layer 3 is formed by depositing a metal 3b such as aluminum on the lower surface of the base film 3a through a synthetic resin layer or an adhesive layer 3c. It is composed of the sandwiched heat-adhesive film layer 3d. This heat-adhesive film 3d is EVA or modified EVA resin or the like, and as will be described below, when the sheet material 1 is manufactured, it is heat-sealed to the sheet base material 2 and the reflection layer 3 is integrated. The composition of the sheet base material 2 is basically the same as that of the sheet base material 2.

The modified EVA resin is an ethylene / vinyl alcohol copolymer in which the acetic acid group of EVA is hydrolyzed to be a hydroxyl group, and is made into a polar ethylene / vinyl alcohol copolymer, which has higher heat resistance, solvent resistance and rigidity than EVA. Of ethylene / vinyl acetate / vinyl alcohol terpolymers that control the degree of hydrolysis of these and are suitable for a wide range of applications. Furthermore, EVA is grafted with vinyl carboxylate compounds for adhesion. Say something with improved power. Further, the base material film 3a is a polyester film or the like, and the synthetic resin layer or the adhesive layer 3c is polyethylene or the like, in short, as long as it can bond the thermal adhesive film and the vapor deposition layer, and is not particularly limited. Not a thing.

An example of the sheet material 1 of the present invention having such a configuration will be described below with reference to FIG. FIG. 3 is a schematic view showing a manufacturing process of the sheet material 1 of the present invention. In the drawing, 4 is a metal vapor deposition film, which basically has the same structure as the above-mentioned reflective layer 3. . The metal vapor deposition film 4 is fed from the feeding roll 5 to the hot roll 8 so that the base film 3a side is in contact with the hot roll 8, and at the same time, the molten synthetic resin 7 contained in the T die 6 is It is melted and dropped onto the metal deposition film 4 (3d side of the thermo-adhesive resin). Then, the air knife 9 arranged in the vicinity of the hot roll 8 sends the air under pressure toward the molten synthetic resin 7 to prevent uneven thickness of the molten synthetic resin 7 and prevent the metal vapor deposition film 4 and the molten synthetic resin 4 from being melted. Resin 7 is designed to be integrated. Subsequently, the integrated sheet material 9 is fed to the hot roll 10, the surface on the side of the molten synthetic resin 7 is flattened by the hot roll 10, and the metal deposition film 4 is formed in the molten synthetic resin 7. The sheet material 1 of the present invention is integrally embedded and manufactured, and is wound on a winding roll 11. That is, the molten synthetic resin 7 corresponds to the above-described sheet base material 2, and the reflection layer 3 is embedded and integrated in the sheet base material 2.

In order to apply the sheet material of the present application configured as described above to the valley of the multi-story house, as an example, as shown in FIG. 4, the arch frame 16 of each house is connected. After the toy mounting base 20 made of metal is horizontally mounted on the connecting member 18, the seat body 1 is placed on the mounting base 20, and the toy fixing metal fittings 24 having the support pipes 22 wrapped at both ends are provided. The seat body 14 is attached by abutting on the seat body 1 and tightening a screw 26 penetrating the toy fixing metal fitting 24, the toy mounting base 20 and the seat body 1 between them. is there. At this time, the seat body 1 is fixedly supported on the toy mounting base 20, and at the same time, both side edges of the seat body 1 are pressed against the arch frame 16 by the elastic force of the seat body 1. Therefore, the seat body 1 can be easily formed into a toy shape.

[Operation and effect of the device]

 According to the toy sheet material of the multi-story house of the present invention, it corresponds to the position of the metal pedestal installed for the work in the valley between the houses of the multi-story house and for laying the sheet material. , A reflective layer consisting of a metal vapor deposition layer is embedded in the longitudinal direction of the base sheet. ・ Since it is integrally formed, the sheet material is deteriorated by reflected heat, radiant heat, and conductive heat.・ The toy sheet material can be easily bent into a U-shape through the boundary line between the reflective layer and the sheet base material, which makes it easy to construct. It is a very good idea.
