Description

  TECHNICAL FIELD The present invention relates to a multi-package of heat insulating heat insulating materials for ducts composed of a laminate of a flexible mat-like heat insulating material used for covering a duct and a sheet-like cover material, and a method for manufacturing the same.

  Conventionally, a heat insulating material made of a laminate of a flexible mat-like heat insulating material and a sheet-like cover material has been used for heat insulation of a duct. As a method of covering the duct with this heat insulating material, for example, when covering the duct with a heat insulating material in a high-rise building, first, a long length composed of a laminate of a flexible mat-shaped heat insulating material and a sheet-shaped cover material is used. The heat insulating material is transported to the site by a truck or other transport vehicle in a roll-wrapped state, and then the roll-insulated heat insulating material is transported by an elevator or the like to the vicinity of a predetermined duct for covering work. At the time of covering work, after cutting the heat insulating material into the required shape on the spot, the cut heat insulating material is placed and moved on a work vehicle at a work place, and the heat insulating material is placed in a predetermined duct. A method of winding and fixing an adhesive tape or the like is employed.

However, the flexible mat-like heat insulating material constituting the heat insulating material is an inorganic fiber such as glass wool or rock wool, and since the thickness is as thick as 25 to 50 mm, the heat insulating material rolled is lightweight. It is very bulky and occupies a large volume during transportation / lifting, so it is inefficient in transportation work, such as increasing the number of times it is transported from a factory to the site by a transport vehicle, or increasing the number of times it is lifted by an elevator, etc. There were many problems and the cost was high.
Further, even at the site, even if the heat insulating material is transported, the work is not always started immediately, and it is often necessary to store it at the site until the time of operation, and it has been difficult to secure a storage place.
Furthermore, since it is cut into a predetermined size at the site and used, a large amount of pieces and residue are generated, which must be treated as waste, and the pieces and residue are scattered at the work site. There was a problem that the environment tends to be messy.

Therefore, as a method for solving the above problem, there is a method disclosed in Japanese Patent Laid-Open No. 09-66978.
For example, in the above publication, there is provided an unpacking method capable of taking out a necessary number of compressed inorganic fiber heat-absorbing sound-absorbing materials and making the remaining inorganic fiber heat-absorbing sound-absorbing materials compact and easy to carry. That is, a predetermined number of mat-like inorganic fiber heat-absorbing and sound-absorbing materials are laminated, compressed in the laminating direction, covered with an outer bag, and sealed. In the bag-like product having a size and shape into which the compressed package can be inserted and having an opening that can be opened and closed along the length direction, the lamination direction of the inorganic fiber heat-absorbing sound-absorbing material is the same as that of the bag-like product. Insulating the inorganic fiber heat-absorbing sound-absorbing material by cutting the surface of the outer bag toward the opening side of the bag-like material in a state where the opening of the bag-like material is opened so as to extend the opening. Is expanded to the full volume of the bag-like material, the necessary number of the inorganic fiber heat-absorbing sound absorbing material is taken out, the opening of the bag-like material is closed, and the remaining portion of the inorganic fiber heat-absorbing sound absorbing material is covered with the bag-like material. This is a method for unpacking a compressed package.
JP 09-66978 A

On the other hand, since the heat insulation material of the roll was carried in the field, and it was cut to the required size on the site and the duct was covered, the heat insulation material was used in the middle of the duct. There wasn't much.
However, in the method described in the above publication, the inorganic fiber heat-absorbing and sound-absorbing material has a size that is easy to construct, for example, a mat having a thickness of 20 to 120 mm, a width of 250 to 500 mm, and a length of about 1200 to 2800 mm. Yes.
This is to make it easy to store a compressed package in which the inorganic fiber heat insulating sound absorbing material is laminated and compressed in the bag or to make the size of the bag into which the compressed package is inserted easy to carry. Because.
Therefore, even if an inorganic fiber heat-absorbing sound-absorbing material having a length of 2800 mm is used, a plurality of inorganic fiber heat-absorbing sound-absorbing materials are required when constructing a duct having a length of 2800 mm or more. In general, when a plurality of inorganic fiber heat-absorbing and sound-absorbing materials are used, a means is adopted in which the seam portion is wound and fixed with another belt-like material such as tape.

However, ducts are often located in high places, and work in unstable places. Especially in the case of a cylindrical duct, the covering part is a curved surface and two inorganic fiber heat-absorbing sound absorbing materials of 1 m or more are arranged. However, it is very difficult to wind and fix the tape at the seam, and the work requires skill, and even if the work is performed by a plurality of workers, the work takes time.
Further, there is a problem that the heat retention effect is lowered when the seam is not sufficiently fixed.

The present invention is a means for solving the above-described problems, that is, it is easy to connect a plurality of heat insulation materials for ducts, and the number of times of transportation by a transport vehicle from the factory to the site, the number of times of lifting by an elevator, etc. The following means for providing a large number of packages for heat insulation and insulation for ducts, which do not require a large amount of storage space at the site, and are excellent in workability without generating heat insulation fragments or excess during operation, and the manufacturing method thereof are provided by the following means.

According to the multi-package of heat insulation materials for ducts of the present invention, the heat insulation material for ducts composed of a laminate of a flexible mat-like heat insulation material and a sheet-like cover material is folded into 2 to 5 folds. A large number of sheets are stacked, compressed, and packed and packed compactly in a bag-like material, so a large amount of heat insulation for ducts can be transported at one time, and the number of transports from the factory to the site is significantly greater than before.

Can do.
And, since the connection work of multiple heat insulation materials for ducts is only fixed with double-sided tape, after adhering the flexible mat-like heat insulation parts of the heat insulation materials for adjacent ducts, sticking with fine adjustment It is possible to reliably perform the covering operation by bringing the flexible mat-like heat insulating materials into contact with each other.
Therefore, skill is not required for the covering operation on the duct, and even a small number of workers can perform the covering operation of the heat insulation material for the duct with a short work period and high work efficiency.

The multi-package of heat insulating heat insulating materials for ducts according to the present invention comprises a laminate of a heat-insulating or heat insulating material, or a flexible mat-like heat insulating material that is used by covering the duct for heat insulating and heat insulating material and a sheet-like cover material.
