（産業上の利用分野）
本発明は、配管等の保温層形成方法及び保温用シートに
関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for forming a heat insulating layer for piping, etc., and a heat insulating sheet.

フォーム等が使用されている。(Conventional technology) Conventionally, as a means of insulating pipes, a heat insulating material or heat insulating material was wrapped around the pipe, or a pair of separate heat insulating materials were assembled from both sides of the pipe, and a dave was wrapped around the pipe to secure it. After that, it is common to paint as necessary. In addition, asbestos, rock wool, glass wool, polyethylene foam, etc. are used as the heat insulating material.
（発明が解決しようとする問題点）
しかし、この種の保温材は、配管の湾曲部分や屈曲部分

なる。(Problems to be Solved by the Invention) However, with this type of heat insulating material, it is extremely difficult to cover curved and bent parts of the pipes, and gaps are created between the pipes and the heat insulating material, resulting in a poor heat retaining effect. There are drawbacks to reducing this. Also,
The insulation material is fixed by wrapping it with tape, which takes a considerable amount of time to install and is not very easy to work with. Furthermore, since the outer periphery of the heat insulating material is painted and dried if necessary, the construction period becomes longer.
（発明の目的）

ある。(Object of the Invention) The present invention has been made in view of the above circumstances, and its purpose is to provide a structure that can be easily installed without creating gaps even in bent portions of pipes and valves, and has excellent workability and heat retention. An object of the present invention is to provide a method for forming a heat insulating layer for piping, etc., and a heat insulating sheet.

We use a foam coating agent called 1,200 to 130 degrees Celsius, in which the butane gas inside expands and foams, and the thickness after foaming reaches 4 to 15 times.

４が設けられている。The foam coating agent 12 is applied to the base film 11 leaving only one side edge, and an adhesive 13 is applied to this negative side edge along the longitudinal direction. It is desirable that the sheet 10 be wound up into a roll in advance and pulled out by the required amount. In addition, a non-adhesive protective tape 1 is applied to the surface of the adhesive 13 so that the sheet 10 in the 1-call state is in close contact with the adhesive 13.
4 is provided.

が向上する。For the base film 11, a heat-shrinkable film or a biaxially stretchable film is used in the case of a thin heat-retaining layer (low foaming), and an aluminum vapor-deposited film is used in the case of a thick heat-retaining layer (high foaming). When an aluminum vapor-deposited film is used, radiant heat from the pipes is reflected on the film, improving the heat retention effect of the sheet 10.

する。Furthermore, in order to prevent moisture from the pipes from having an adverse effect on the heat insulating layer, the surface of the foamed coating agent 12 is covered with a film 11a, as can be seen from FIG. The film 11a is made of the same material as the base film 11.

〜を使用する場合は、発泡コーティング剤１２の層が内
側になるように取付ける。Next, a method for attaching the heat insulating sheet 10 will be explained. First, a required amount of sheets 10 is pulled out from a roll of sheets 10 and cut as shown in FIG. Subsequently, the protective tape 14 is peeled off, and the sheet 10 is wrapped around the pipe 15 as shown in FIGS. 4 and 5, and both ends of the sheet 10 are joined with the adhesive 13. Sheet 1 without covering film 11a
When ~ is used, it is installed so that the layer of foam coating agent 12 is on the inside.
従来のテープ巻きと異なり、シート１０は引張りながら
配管１０に巻付けられ、そのまま両端が接合されるから
、シート１０が緩んだり、保温層と配管１５との間に隙
間が生ずることはない。Unlike conventional tape wrapping, the sheet 10 is wrapped around the piping 10 while being stretched, and both ends are joined as is, so the sheet 10 will not loosen or a gap will occur between the heat insulating layer and the piping 15.
この手法は、配管現場で発泡コーティング剤１２を加熱
弁ｒ８Ｎできない場合、特に有効である。また、基材フ

及び乾燥工程を省略できる。This method is particularly effective when it is not possible to heat the foam coating agent 12 at the piping site. Moreover, since the base film 11 can be colored, the steps of painting and drying the outer surface of the sheet can be omitted.
配管１５が長い場合には、シート１０を何段かに分けて
取付け、各シート１０の継目を基材フィルム１１と同種
のフィルムで被覆すれば綺麗に仕上げられる。If the piping 15 is long, the sheets 10 can be installed in several stages and the joints of each sheet 10 can be covered with a film of the same type as the base film 11 to achieve a neat finish.

ト１０を配管１５に対して螺旋状に巻きつけている。Also shown in FIGS. 6 and 7 are different uses of the sheet 10. In the embodiment of FIG. 6, the adhesive 13 of sheet 10 is used to cover the seam between adjacent sheets. That is, the adhesive 13 portion of the sheet 10 is attached to the pipe 15 with the adhesive 13 on the right side in FIG.
It is pasted around the top of the . In the embodiment shown in FIG. 7, the sheet 10 is wound around the pipe 15 in a spiral manner.
このような構成にすれば、各シート１０の継目を特別に
後処理する必要はなくなる。With such a configuration, there is no need to specially post-process the seams of each sheet 10.
