【考案の詳細な説明】
本考案は主としてビニルハウスに用いられる農業用シー
トの改良に関するものである。[Detailed Description of the Invention] The present invention mainly relates to improvements in agricultural sheets used in vinyl greenhouses.
ビニルハウスはイチゴ等の栽培に広く用いられている。Vinyl greenhouses are widely used for growing strawberries and other crops.
ところで、従来のビニルハウスはポリ塩化ビニル等のシ
ートをハウス骨組上に被覆させたものであり、通気性が
無いために夜間にネ゛いて、ハウス内の水分が露結し易
く、天井部分の露結水分の落下による冷却作用によって
、・・ウス内め日中の蓄湿を大幅に消費する欠点があっ
た。By the way, conventional vinyl houses are made by covering the frame of the house with a sheet of polyvinyl chloride, etc., and because they have no ventilation, moisture inside the house tends to condense when the house is lying at night, and the ceiling part is prone to condensation. Due to the cooling effect of the falling dew water, there was a drawback that the moisture accumulated during the day was consumed significantly.
本考案は従来品の有する上記問題を解決した農業用シー

製多孔質シートによシ被覆閉塞されて成るものである。The present invention relates to an agricultural sheet that solves the above-mentioned problems of conventional products. A thermoplastic sheet is cut out at a predetermined portion, and the cutout is provided with a hot-melt adhesive on one side in the form of a mesh. It is covered and closed with a porous sheet made of fluororesin that has both water repellency and water repellency.
以下、図面により本考案の実例を説明する。Hereinafter, examples of the present invention will be explained with reference to the drawings.
第１図にふ・いて、１はポリ塩化ビニル、ポリエチレン

のフッ素樹脂製多孔質シート３により被覆閉塞されてい
る。Referring to Figure 1, 1 is made of polyvinyl chloride, polyethylene, polypropylene, etc. and has a thickness of 0.05 to IWanO.
It is a long thermoplastic plastic sheet, and is notched along its longitudinal direction, and the cutout part 2 is slightly wider than that, and by providing countless micropores with a pore diameter of 0.2 to 10μ, It is covered and closed with a band-shaped porous sheet 3 made of fluororesin that has both air permeability and water repellency.

チックシート１に接合せしめている。As shown in FIG. 3, a hot melt adhesive 4 is provided in a mesh pattern on one side of the fluororesin porous sheet 3, and the porous sheet 3 is bonded to the thermoplastic sheet 1 by the adhesive 4. It's forcing me.
従って、多孔質シート３の熱可塑性プラスチックシート
１の切欠部２の被覆閉塞は容易であり、また多孔質シー
ト３がホットメルト接着剤４によシ網目状に補強された
形になるので耐久性が向上する。Therefore, it is easy to cover and close the notch 2 of the thermoplastic sheet 1 of the porous sheet 3, and since the porous sheet 3 is reinforced in a mesh shape by the hot melt adhesive 4, the durability is improved. will improve.
