It is a straight pipe made of glass wool solidified with a resin binder, the surface of which is bonded with aluminum foil. However, since they are not flexible, flexible ducts made of glass wool are used in places where flexibility is required in order to increase the efficiency of construction (Japanese Utility Model Publication No. 51-37214).

可能な送吸気用ダクトを供給することを目的とする。However, when glass wool is wound around a metal pipe, it is necessary to perform heat insulation work by a specialized company at a later date. To solve these problems, ducts made of glass wool solidified with a resin binder can shorten the construction period.However, since the ducts are hardened, they have no flexibility. I had to. Also, the flexible duct using glass wool of Japanese Utility Model Publication No. 51-37214 and Japanese Utility Model Application Laid-Open No. 59-122480 has a problem that when cut into an arbitrary length, the glass wool directly touches hands and irritates the skin. Was.
To solve these problems, Japanese Unexamined Patent Publication No. Hei 8-247348 proposes a flexible duct hose. However, since the surface is covered with resin, there is a possibility of dew condensation on a ceiling or the like in summer. JP-A-8-14490 proposes a heat-insulated double pipe made of a band-shaped body in which a non-woven fabric is laminated on the surface of a resin film. The outer pipe must be cut by different cutters, and the gap formed between the inner pipe and the outer pipe at the cut portion must be sealed with a sealing material, which poses a problem in workability. The present invention has been devised to solve these problems, has heat insulating properties and dew condensation prevention performance, can be used as a straight pipe and a bent pipe, and has no problem in workability even when arbitrarily cut. It is an object of the present invention to supply a long-form air-intake / intake duct by continuous molding.

能である。Next, the present invention will be described with reference to the drawings. FIG. 1 shows an example of a fiber layer strip 1 used in the present invention. The fiber layer 2 and a resin sheet or film 3 are shown.
1 is a perspective view of a strip 1 of a fiber layer obtained by laminating and slitting. FIG. 2 is a plan view showing an example of the present invention and showing a partial cross section of the air intake / suction duct. First, the strip 4 of the resin sheet or film is spirally wound with an overlap portion, and the reinforcing member 5 is sandwiched and fused in the overlap portion to form the inner tube 6. Next, a foam band 7 cut into a fixed width is spirally wound on the inner tube 6 over the entire tube. The foam band 7 can be wound so as to form an overlapping portion, but can be wound so that the foam band 7 comes into contact without providing an overlapping portion as shown in FIG. Is preferable because uniform heat insulating properties can be imparted throughout. Next, the resin sheet or film 3 of the band 1 of the fiber layer shown in FIG. 1 is heated and melted, spirally wound around the band 7 of the foam, and the space between the reinforcements 5 is reinforced from the outer surface of the tube with a disk-shaped roller or the like. Hold down while heating parallel to the body direction to shape the valley shape. In this case, it is preferable that the belt-like body 1 of the fiber layer is wound so as to form an overlapping portion as shown in FIG. 2 because the band-like bodies can be firmly bonded. The shaping of the crests 8 and the valleys 9 may be performed by pushing up the space between the reinforcements in parallel with the direction of the reinforcements while heating the inner surfaces of the pipes with a disk-shaped roller or the like. As a method of forming the air supply / intake duct, a method of spirally winding any of the fiber layer strip 1, the foam strip 7, and the resin sheet or film strip 4 is preferable, but is not limited thereto. Alternatively, a method of making all or part of them sushi rolls is also possible.

ンシートが融着性がよく好適である。In the present invention, typical examples of the fiber layer 2 include a woven fabric and a nonwoven fabric, but a nonwoven fabric is the best.
The non-woven fabric reduces the temperature difference between the heat-insulating duct and the environment,
In addition to being able to prevent the occurrence of dew condensation by relaxing the air held in the nonwoven fabric, the generated dew can be dispersed inside to prevent dripping of the dew condensation. As the nonwoven fabric having these features, a nonwoven fabric using fibers of 5 denier or less and having a thickness of 10 μm to 5 mm and a basis weight of about 0.5 to 300 g / m 2 is preferable. Examples of the fiber material include polyester, polyamide, polyolefin (polyethylene, polypropylene, etc.), polyacrylonitrile, polyvinyl alcohol (vinylon), and the like. Of these, polyester is preferable. Although the fiber layer may be directly bonded to the foam layer, it is efficient to laminate the fiber layer to the resin sheet or film 3 and to melt-bond the resin sheet or film 3 to the foam layer. This is preferable because the belt-like body 1 can be attached to the outside of the inner tube.
The thickness of the resin sheet or film is 50μ ~
A non-stretched polyethylene sheet having a melting point of 0.5 mm and a melting point of 80 to 120 ° C. is suitable because it has a good fusion property.

Example 1 A 100 μm-thick unstretched polyethylene sheet was slit to a width of 35 mm to form a strip of an inner tube resin sheet. The belt-shaped body of the resin sheet for the inner pipe is spirally wound with a width of the overlapping portion of about 10 mm, and the overlapping portion is simultaneously heated with a non-frame torch so that a hard steel wire (reinforcing body) having a wire diameter of 1.0 mm is substantially formed at the overlapping portion. The inner tube was formed by heat fusion at the center. On the outside of the inner tube, a band of foam obtained by slitting a polyethylene foam having a thickness of 10 mm and a foaming ratio of 40 times to a width of 25 mm, as shown in FIG. 2, without providing an overlapping portion on the inner tube, It was spirally wound so that the end faces contacted. On the other hand, a 100 μm thick polyethylene sheet is laminated on a nonwoven fabric having a basis weight of 30 g / m 2 using 3 denier polyester fiber,
A laminate having a thickness of 150 μm was formed, and this laminate was further
The slit was cut to a width of m to obtain a fiber layer strip shown in FIG.
The polyethylene sheet surface of the strip of the fiber layer was melted with a non-frame torch, and spirally wound so as to form an overlapped portion on the pipe surface while being melt-bonded to the polyethylene foam. The bellows shape is formed by pressing the reinforcements by heating them in a direction parallel to the reinforcements by using a disk-shaped roller or the like, and forming a valley shape so that the inner diameter below the peaks (below the reinforcements 5 in FIG. 2) is reduced. A 100 mm heat insulating duct (FIG. 2) was obtained.
