Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention has a function at a construction site.
The present invention relates to a compression jig for an integrated flexible duct.

[0002]

2. Description of the Related Art Generally, in building equipment, a main duct path or a branch duct path that joins or branches to the main duct path is used for guiding air to a predetermined place during air conditioning and ventilation. For example, an iron plate spiral duct is used for the branch duct path. The iron plate spiral duct is manufactured by winding a strip-shaped zinc iron plate in a coil spring shape.

In order to construct a branch duct path having a predetermined length by installing an iron plate spiral duct at a construction site, the following series of steps are required. The series of steps is (1) a manufacturing step of manufacturing a steel plate spiral duct configured as a straight pipe with a predetermined pipe diameter in a workplace,
(2) Loading process of multiple iron plate spiral ducts on the truck at the work place, (3) Transportation process of transporting the multiple iron plate spiral ducts from the work place to the construction site by the truck, (4) At the construction site Unloading process of multiple iron plate spiral ducts from trucks, (5) Small transport process of iron plate spiral ducts in a building site, (6) Iron plate according to the length and shape of branch duct route in building site Dimensioning and cutting process of spiral ducts made of steel, (7) Installation process of fittings and suspension bands for multiple spiral ducts made of iron plates, (8) Connection for suspending multiple spiral ducts made of iron plates to form a branch duct path Process, (9)
The process consists of covering the surface of the iron plate spiral duct with a heat insulating material such as glass wool or tape. In addition,
The above heat insulation material coating step is necessary to cover the outer periphery of the iron plate spiral duct with the heat insulation material because the heat of the air passing through the inside is easily transmitted to the outside only by connecting the plurality of iron plate spiral ducts. To be done.

However, looking at the process from the work place to the construction site until the above-mentioned installation work of the iron plate spiral duct is carried out at the construction site to form a branch duct path of a predetermined length, the following problems are encountered. There is.

(3) In the transportation process, in order to correspond to a branch duct path (for example, 12 m) of a predetermined length to be installed at a construction site, a plurality of iron plate spiral ducts (length 4 m × 3) It is necessary to transport the book) to the construction site. Therefore, the iron plate spiral duct occupies the volume corresponding to the branch duct path, the volume of the iron plate spiral duct increases, and the transportation cost is high.

In the (2) loading process, (4) unloading process and (5) small transporting process, since the volume of the spiral duct made of iron plate increases, there is a risk that the load collapses when stacked in multiple stages. However, even in the case of small transportation, it is not possible to use a transportation container such as a container, and it depends on manpower. In addition, a large number of areas are required to collect the iron plate spiral ducts.

[0007]: Each of the spiral ducts made of iron plate is dimensioned and cut in accordance with the space of the construction site so as to match the length and shape of the branch duct path to be installed, and cut. In addition, it takes a lot of time to match the site in the installation process, and it occupies the site space, which is an obstacle to other work at the construction site. Further, the scrap material of the iron plate spiral duct after cutting the iron plate spiral duct of a required length and performing on-site alignment becomes waste and becomes waste.

[0008] The iron plate spiral duct arranged as the branch duct path needs to be covered with a heat insulating material, and the heat insulating material, tape, etc. are aligned and cut on the iron plate spiral duct at the site to cut the heat insulating material. Pieces of tape, etc. are generated and waste is created.

Further, the branch duct path requires a predetermined length. The length of the iron plate spiral duct made of a straight pipe made in the workplace is limited due to the length limitation in transportation, and a plurality of iron plate spiral ducts are required to form a predetermined branch duct path. Therefore, many joints for connecting the iron plate spiral ducts are required, and there is a problem that the connecting work is required.

(9) In the heat insulation material coating step,
A thermal insulation material is wound around a plurality of spiral ducts made of iron plates to form a coated end material, and the coated end material becomes waste and is wasted.

Since the iron plate spiral duct uses a zinc iron plate as a material, (8) when working in the connecting step, the large and bulky iron plate spiral duct is heavy for an operator to lift by hand and work. There is a problem that it is difficult to hang.

As described above, since the branch duct path having a predetermined length is formed by connecting the plurality of iron plate spiral ducts through the joint, the plurality of iron plate spirals are formed from the work site to the construction site. A duct connecting step and a heat insulating material covering step are required, and there are problems associated therewith.

Further, as a method of constructing a flexible duct at the construction site, which omits the work of connecting the above-mentioned iron plate spiral duct, for example, a method disclosed in Japanese Patent Publication No. 5-44577 is known.

FIG. 29 shows a method of constructing a duct path according to Japanese Patent Publication No. 5-44577. In the figure, a duct 101 includes a frame member 102, an outer cover member 103,
The core tube 104.

The frame member 102 is assembled in a cubic shape and connected in a long gabion shape. The skin material 103 is a protective material such as a curing net, and is attached to the four peripheral surfaces of the frame material 102. The core tube 104 is a long tube, and is a flexible film tube having airtightness and incombustibility used for an air dome or the like.

During storage, the frame member 102 of the duct 101 is shortened in a bellows shape, and is stretched to a fixed length during construction. Frame material 1
A predetermined number of 02 are connected, an outer skin material 103 is attached to the four circumferential surfaces thereof, and a core tube 104 of a predetermined length is inserted into an outer shell in which the outer skin material 103 is attached to the frame material 102.

The outer skin material 103 and the core tube 104
An incombustible material can be used for the.

[0018]

However, Japanese Patent Publication No. 5-
In the method of constructing a flexible duct according to Japanese Patent No. 44577, the frame member 102 of the duct 101 is shortened in a bellows shape and is stretched to a fixed length during construction. Therefore, the above-mentioned joint for connecting the iron plate spiral duct is unnecessary. However, there are the following problems.

Generally, flexible ducts installed at construction sites are required to have various functions such as elasticity, strength, heat insulation, sealing properties, and fire protection. Further, when a flexible duct is installed at a construction site, it is required to eliminate the assembly work for adding a function to the flexible duct and shorten the process.

However, in the above flexible duct construction method, a predetermined number of frame members 102 are connected, and the outer cover member 103 is attached to the four peripheral surfaces thereof, and then the outer cover member 103 is attached to the frame member 102.
In order for the core tube 104 of a predetermined length to be inserted into the outer shell to which is attached, it is necessary to carry the outer shell and the core tube 104 to the work site and assemble them. That is, the necessary functions of the duct 101 are not integrated. Therefore, assembly work is required at the construction site.

Further, the duct 101 has a core tube 104 of a predetermined length in an outer shell in which an outer skin material 103 is attached to a frame material 102.
Since it is made by inserting a heat insulating material, if there is no heat insulating property, and if you try to add a function to the heat insulating material to the duct 101, you can align the heat insulating material, tape, etc. to the duct 101 at the site as well as the iron plate spiral duct. Pieces of heat insulating material, tape, etc. generated by cutting will be generated, and waste will be generated. Then, as a duct material used for the main duct path or the branch duct path, the actual fair 4-484 is used.
The one shown in Japanese Patent No. 29 is known. The duct material disclosed in this publication is composed of a single glass fiber cloth layer, a steel wire with an adhesive which is spirally wound around the outer circumference thereof, a sound absorbing material layer which is wound around the outer circumference thereof, and a synthetic material which is fitted on the outer circumference thereof. And a resin coating layer.

However, in the duct material disclosed in Japanese Utility Model Publication No. 4-48429, since the sound absorbing material layer is wound around the outside of the steel wire with the adhesive in advance, the sound absorbing material layer is thermally insulated. It fulfills its function and the construction process of covering the surface of the iron plate spiral duct with a heat insulating material is not necessary. However, after the construction work of this duct is performed, if the construction with welding or other fire is carried out, Since the outermost layer of the duct material is composed of the synthetic resin coating layer, damage may occur due to welding sparks and the like, and the duct material may be forced to be repaired.

Alternatively, a flexible duct with glass wool may be used to connect the branch duct route to the main duct route. Although the flexible duct with glass wool is light and has good workability, its outer material is weak and the length during manufacturing is limited, so that it is generally limited to use as a connecting short pipe. Is.

By the way, as a flexible duct with glass wool, the one shown in Japanese Utility Model Laid-Open No. 4-136445 is known as shown in FIG. In the figure, the flexible duct 20 with glass wool shown in this publication
Reference numeral 1 denotes a core material 202 formed by winding a metal wire rod in a coil shape, an inner surface sheet 203 made of a non-woven fabric, a glass wool 204, and an outer surface sheet 205 made of polyvinyl chloride, which are wound in order to form a cylindrical shape. Is fixed to the inner surface sheet 203 with an adhesive.

In order to solve the problems in the method of constructing a flexible duct according to Japanese Patent Publication No. 44577/1993 (which requires assembly work at a construction site and lack of heat insulation), the glass wool having such a structure is used. It is also conceivable to put the attached flexible duct 201 in a compressed state in a work place in advance and extend it at a construction site. in this case,
Since the core material 202 is fixed to the inner surface sheet 203 with an adhesive, the core material 202 deforms when compressed, so that the core material 202 and the inner surface sheet 203 may be separated from each other. Therefore, the flexible duct 201 with glass wool is not configured to expand and contract.

Further, after the construction work of the flexible duct 201 with glass wool is carried out and the construction with fire is carried out such as welding, the outermost layer of the flexible duct 201 with glass wool is an outer sheet made of polyvinyl chloride. Since it is composed of 205, there is a case where damage is caused by a spark of welding or the like and the duct material is forced to be repaired.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to provide a compression jig for a flexible duct when a duct path is installed at a construction site.
