板、鉄板などの剛性の高い材料が使用されている。[Prior Art] Generally, in a heat insulating construction method in which a heat insulating layer is formed by spraying a heat insulating foam resin such as urethane foam, a highly rigid material such as concrete, plywood, or an iron plate is used as a base material for spraying the heat insulating foam resin. ing.
このような剛性の高い下地材が使用される理由は、下地
材として帆布等の可撓性のシートを使用した場合に次の
ような問題を生じるからである。The reason why such a highly rigid base material is used is that the following problems occur when a flexible sheet such as canvas is used as the base material.

円弧状に大きく波打った状態で固定され、外観が非常に
悪くなる問題があった。That is, when the heat-insulating foamed resin foams, it foams in all directions such as up, down, front and back, and left and right.
As shown in (a), since the heat insulating foam resin (7) is sprayed on one side of the flexible sheet (6), as shown by the arrows in FIGS. The resin (7) foams laterally and upward, and hardens after several tens of seconds to several minutes. At this time, the adhesive surface between the sheet and the heat-insulating foamed resin is fixed as the gelation progresses, but the sheet (6 ), A compressive stress acts on the sheet (6), and the compressive stress causes the sheet (6) to largely bend and project upward. Therefore, as shown in FIG. There was a problem that the appearance was very bad.
本発明は、上述の実情に鑑みて勘案されたものであり、
その目的は、可撓性のシートでも波打ちの少ない状で断
熱発泡樹脂を吹き付けることができるようにする点にあ
る。The present invention has been considered in view of the above circumstances,
The purpose thereof is to make it possible to spray the heat-insulating foamed resin even in a flexible sheet with less waviness.

撓性シートに断熱発泡樹脂を吹き付けて断熱層を構成し
てある事を特徴とするものであり、それによる作用・効
果は次の通りである。The heat insulating construction method for a sheet according to the present invention is such that a flexible sheet is provided with a bendable reinforcing membrane material having a permeation path that allows the heat insulating foamed resin to pass therethrough, and the flexible membrane material is flexible from the side of the reinforcing membrane material. This is characterized in that a heat insulating foamed resin is sprayed onto the sheet to form a heat insulating layer, and the action and effect thereof are as follows.
補強膜材側から可撓性シートに断熱発泡樹脂を吹き付け

トの上方への湾曲突出量を減少することができる。When adiabatic foamed resin is sprayed onto the flexible sheet from the side of the reinforcing membrane, a part of this adiabatic foamed resin adheres to the sheet through the permeation path of the reinforcing membrane, and the foaming state progresses to foaming / gelling / curing. . At this time, the heat-insulating foamed resin adhered to the sheet and the reinforcing film material foams in the upward and lateral directions. In particular, the lateral movement due to the foaming of the heat-insulating foamed resin is suppressed by the reinforcing film material. The compressive stress acting on the sheet portion adhered to the heat-insulating foamed resin can be considerably reduced, and the upward curving amount of the sheet can be reduced.
従って、可撓性シートに補強膜材を介して断熱発泡樹脂

対して有効である。Therefore, the thermal insulation layer can be formed in a state with less waviness as compared with the conventional art, while only the thermal insulation foamed resin is sprayed on the flexible sheet through the reinforcing film material, so that the film structure such as a tent is formed. Also, the heat insulation treatment can be advantageously performed in terms of construction period and construction cost. In particular, it is effective for agricultural-related facilities such as mushroom cultivation, poultry houses and pig houses, where economic efficiency is particularly required.
