Disclosure of Invention
The "air conditioning plenum box supporting structure" described in patent document 1 is a structure for supporting an air conditioning plenum box by using suspension bolts suspended substantially perpendicularly from a ceiling body toward an indoor space side, and therefore a step of driving and fixing a plurality of suspension bolts into the ceiling body is required. In addition, in this driving step, since the suspension bolt needs to be attached by positioning the suspension bolt in alignment with the through hole of the suspension of the air conditioning plenum supported by the suspension bolt, the layout of the air conditioning plenum and the construction of the suspension bolt are troublesome.
Further, since other devices than air-conditioning ducts and lighting are disposed in the space behind the ceiling of the building, it is impossible to change the position of the suspension bolt after first being installed in a coordinated relationship with other devices. Further, even in the air conditioning reconditioning process, since positioning and mounting of the suspension bolt occurs for each of the air conditioning plenum boxes that are newly set up, a lot of labor and time are required, and therefore the air conditioning reconditioning process cannot be easily applied.
Therefore, an object of the present invention is to provide an air conditioning plenum box installation structure that is easy to install, can easily cope with an air conditioning modification process, and is excellent in safety.
The invention provides an air conditioner static pressure box arrangement structure, which is characterized in that the air conditioner static pressure box arrangement structure comprises: a system ceiling formed by arranging a plurality of T-shaped keels to construct a ceiling in a building; a plenum box for an air conditioner, which is placed on the T-shaped keel forming at least one section of the system ceiling or is disposed in a section formed by the T-shaped keel; and a fixing member attached to the static pressure box for an air conditioner so as to fix the static pressure box for an air conditioner to the T-shaped keel by engaging with the T-shaped keel, the static pressure box for an air conditioner including: a housing formed in a rectangular parallelepiped shape; an air inlet opening in the front surface of the housing; and a plurality of air outflow ports opened to a side surface portion of the housing, the fixture having: a tongue-shaped support portion suspended from a front edge portion and a rear edge portion of a bottom surface portion of a housing of the plenum box for air conditioning; and a clamping portion fastened to an outer surface of the support portion, the clamping portion being capable of elastically gripping the T-shaped keel from a ceiling back side.
With this configuration, the air conditioning plenum box can be installed in the ceiling rear area by simply being placed on the T-shaped keel without using a suspension bolt fastened to the body of the building, and therefore, the air conditioning plenum box can be easily installed, and the air conditioning plenum box can be easily and appropriately handled in the air conditioning repair process. Because the static pressure case for the air conditioner is integrally fixed on the T-shaped keel through the fixing piece clamped with the T-shaped keel, the static pressure case for the air conditioner cannot shift or fall off when an earthquake occurs, and the safety is excellent.
With such a configuration, the engagement operation of the fastener with respect to the T-shaped keel becomes easy, and workability is effectively improved, and the drop prevention function at the time of an earthquake is also improved.
On the other hand, the air conditioning plenum box can be formed of a corrugated cardboard material with noncombustible metal foil stuck to both sides.
With such a configuration, the weight of the plenum box is reduced as compared with a conventional metal plenum box for an air conditioner, and the load of the installation work can be reduced to realize safe installation. In addition, even if the static pressure box for air conditioning drops off from the system ceiling and falls into the room, the static pressure box for air conditioning has a light weight, so that a major accident can be avoided and the safety is improved. Further, since the corrugated paper material has better heat insulation than the metal material, the heat insulation of the entire plenum box for air conditioning can be improved, and the waste of air conditioning energy can be reduced without requiring separate heat insulation work or the like.
According to the present invention, it is possible to provide an air conditioning plenum box installation structure that is easy to construct, can easily cope with air conditioning modification processes, and is excellent in safety.

Detailed Description
The following describes a plenum box installation structure 100 for an air conditioner, a method of installing the plenum box, and the like, which are embodiments of the present invention, with reference to fig. 1 to 8.
As shown in fig. 1, the static pressure box installation structure 100 for an air conditioner of the present embodiment includes: a grid ceiling 10, which is 1 type of system ceiling, and is formed by arranging a plurality of T-shaped keels 11 in a grid shape so as to construct a ceiling in a building; a plenum box 20 for an air conditioner, which is placed on a T-shaped keel 11 forming at least one section of the grid ceiling 10; and a plurality of fixing members 30 attached to the plenum box 20 for air conditioning so as to fix the plenum box 20 for air conditioning to the T-shaped keel 11 by engaging with the T-shaped keel 11.
In the present embodiment, the dimension of 1 partition of the grid ceiling 10 is 600mm × 600mm, and the plenum box 20 for air conditioning is a dimension one turn smaller than the dimension of the 1 partition. Further, the partition size of the grid ceiling 10 has a specification of 640mm × 640mm in addition to 600mm × 600 mm.
As shown in fig. 2 to 5, the plenum box 20 for air conditioner includes: a housing 21 formed in a rectangular parallelepiped shape; an air inlet 22 opened in the front face 21a of the casing 21; a plurality of air outlets 23 opened in the side surface 21b of the casing 21; and a fixing member 30 that is attached to the side edge 21d and the side edge 21e of the bottom surface 21c of the housing 21 in a hanging manner.
The air inlet 22 of the front surface portion 21a of the casing 21 is an opening portion connected to a duct (not shown) branched from the main air-conditioning duct, and the air outlet 23 of the side surface portion 21b of the casing 21 is an opening portion separately provided for connection to an air-conditioning outlet provided in a ceiling through an arbitrary unit such as a flexible duct.
The housing 21 of the plenum box 20 for air conditioning is formed by: a plurality of flat corrugated paper materials each having a nonflammable metal foil adhered to both surfaces thereof are combined to form a rectangular parallelepiped shape (hexahedral shape), and an alumina tape is adhered to a joint portion between edge portions of the corrugated paper materials.
As shown in fig. 3, the fixing member 30 has: a tongue-shaped support portion 31 that hangs down from the side edge portions 21d and 21e of the bottom surface portion 21c of the housing 21 of the air conditioning plenum box 20; and a plurality of clamping portions 32 fastened to the outer surface of the support portion 31.
An upper half 32a of the clip portion 32 having an L-shaped cross section is fastened to the outer surface of the support portion 31, and a lower half 32b of the clip portion 32 having a J-shaped cross section is provided with a gap G from the outer surface of the lower half 31b of the support portion 31. In the present embodiment, the support portion 31 is formed of an iron plate material, and the clip portion 32 is formed of a spring material, so that the T-shaped runner 11 of the grid ceiling 10 can be elastically held from the ceiling back side in the gap G formed between the clip portion 32 of the fixing member 30 and the support portion 31, as will be described later.
Next, a method of mounting the plenum box installation structure 100 for an air conditioner shown in fig. 1 and the like will be described with reference to fig. 6 to 8.
As shown in fig. 6, in the grid ceiling 10 formed by arranging a plurality of T-shaped keels 11 in a grid pattern, the plenum box 20 for air conditioning is carried from the indoor side to the ceiling back above the grid ceiling 10. In this case, since the air conditioning plenum box 20 is formed to have a size one turn smaller than 1 section of the grid ceiling 10, the air conditioning plenum box 20 can be carried into the ceiling rear surface through the section 13 to which the ceiling plate 12 is not attached among the plurality of sections formed by the grid-like T-shaped runners 11. This carrying-in operation is performed by vertically lifting the air conditioning plenum 20 from directly below the partition 13 toward the ceiling rear area while keeping the front surface portion 21a in a posture directed directly above.
Next, as shown in fig. 7, the static pressure tank 20 for air conditioning is set to the original posture (the posture in which the bottom surface portion 21c is directed downward), and the static pressure tank 20 for air conditioning is moved to the partition 14 where the ceiling plate member 12 is mounted, which is the predetermined installation position of the static pressure tank 20 for air conditioning. After that, when the air conditioning plenum box 20 is lowered toward the partition 14, the fixing member 30 of the air conditioning plenum box 20 is engaged with the T-shaped runner 11 from the ceiling back side through the process shown in fig. 8, and the air conditioning plenum box 20 is fixed to the T-shaped runner 11.
Specifically, as shown in fig. 8(a), the vertical cross-sectional shape of the T-shaped runner 11 is a shape similar to the cross-sectional shape of the railway rail whose central portion is narrowed, and since the clamping portion 32 is elastically deformable, when the air conditioning plenum 20 is lowered, the outer surface of the support portion 31 comes into sliding contact with the T-shaped runner 11 to function as a guide, and the gap G portion of the fixing member 30 is pressed from the ceiling back side toward the upper edge portion 11a of the T-shaped runner 11, and the clamping portion 32 is elastically deformed outward and the gap G is opened, so that a part of the upper edge portion 11a of the T-shaped runner 11 is fitted into the gap G, as shown in fig. 8 (b).
Thereafter, when the air conditioning plenum box 20 is further lowered, the clip portion 32 is further elastically deformed to temporarily expand the gap G to a large extent, and after the entire upper edge portion 11a of the T-shaped runner 11 is fitted into the gap G, the clip portion 32 returns to the original state, and the fastener 30 is in a state of gripping the upper edge portion 11a of the T-shaped runner 11, so that the air conditioning plenum box 20 is fixed to the T-shaped runner 11. After that, the ceiling plate 12 is attached to the partition 13, and the state shown in fig. 1 is obtained.
Then, when the air inlet 22 is connected to a branch pipe (not shown) branched from the main air-conditioning duct and an air outlet 23 and an air outlet (not shown) provided in a ceiling are connected to each other by a flexible duct or the like (not shown), the air-conditioning air sent from the main air-conditioning duct is distributed to each air outlet in the air-conditioning plenum box 20, and the air-conditioning air can be supplied to the space to be air-conditioned.
As shown in fig. 1, in the air conditioning plenum box installation structure 100 of the present embodiment, since suspension bolts fastened to the body of a building are not used, the installation of the air conditioning plenum box 20 is easy, and the air conditioning plenum box installation structure can be easily and appropriately applied to an air conditioning modification process. Since the plenum box 20 for air conditioning is integrally fixed to the T-shaped keel 11 by the fixing member 30 that grips the T-shaped keel 11, it does not shift or fall off during an earthquake, and is excellent in safety.
Since the fixing tool 30 has the holding portion 32 capable of elastically holding the T-shaped runner 11 from the back side of the ceiling, the fixing tool 30 can be easily engaged with the T-shaped runner 11, workability is effectively improved, and an excellent drop prevention function is exhibited when an earthquake occurs.
Since the housing 21 of the air conditioning plenum box 20 is formed of a plurality of flat corrugated sheets each having a non-combustible metal foil adhered to both surfaces thereof, the plenum box 20 is reduced in weight and improved in workability. In addition, even if the static pressure tank 20 for air conditioning drops by chance at the time of an earthquake or the like, since the housing 21 itself is light in weight, a serious accident can be avoided, and safety is improved. Further, since the corrugated paper material having the nonflammable metal foil stuck on both surfaces has excellent heat insulation property as compared with the metal material, the heat insulation property of the whole air conditioning plenum box 20 can be improved, and waste of air conditioning energy can be reduced.
The fixing member 30 of the present embodiment is formed of a metal material, but the present invention is not limited thereto, and the fixing member 30 may be formed of a synthetic resin material having lower thermal conductivity than the metal material. In this case, during cooling operation, it is possible to prevent cold air from being sent from the plenum box 20 for air conditioning to the T-shaped keel 11 via the fixing member 30.
Further, since the fixing member 30 is in contact with the T-shaped keel 11 in a state where the T-shaped keel 11 made of metal is gripped, if the fixing member 30 is made of synthetic resin, it is possible to suppress propagation of sound and vibration generated by the flow of air-conditioning air in the air-conditioning plenum box 20 during air-conditioning operation to the ceiling, and to ensure electrical insulation between the air-conditioning plenum box 20 and the T-shaped keel 11. Further, in order to prevent the transmission of vibration and sound into the room, a buffer material, a vibration damper material, or the like may be appropriately interposed between the fixing member 30 and the T-shaped runner 11.
The installation form of the air conditioning plenum box 20 on the grill ceiling 10 is not limited to the form shown in fig. 1, and for example, the air conditioning plenum box 20 may be installed from at least one section of the grill ceiling 10 toward the room so that the bottom surface portion 21c of the housing 21 of the air conditioning plenum box 20 having the same surface finish as the ceiling plate 12 is exposed from the bottom surface portion 21c of the housing 21 of the air conditioning plenum box 20 having the surface finish.
With such a configuration, since the bottom surface portion 21c of the casing 21 of the air conditioning plenum box 20 can function as the ceiling plate material, it is possible to provide the same design and appearance as the other ceiling plate materials 12 arranged in the other partition of the grille ceiling 10, and it is not necessary to arrange the ceiling plate materials 12 in the partition, thereby making it possible to achieve the ease and labor saving of construction, the simplification of the ceiling structure, and the reduction of the ceiling plate materials. Further, the dimension of the plenum box 20 for air conditioning is substantially equal to the dimensions of the partitions 13 and 14, and if the width dimension of the front surface portion 21a of the housing 21 is reduced, it is possible to arrange devices such as lighting equipment in the same partition.
In the present embodiment, the case where the outer case 21 of the air static pressure tank 20 is formed of a corrugated cardboard material with incombustible metal foil stuck to both surfaces thereof has been described, but the present invention is not limited thereto, and the outer case 21 may be formed of an iron plate with a heat insulating material stuck to the inner surface, or the outer case 21 may be formed of a glass fiber plate made of compressed glass wool or another material having heat insulating properties.
The fixing method of fixing the fixing member 30 to the static pressure box 20 for air conditioning is not limited to this embodiment, and a method of fixing the fixing member to the static pressure box 20 for air conditioning using an adhesive or an adhesive tape may be employed, or in the case of an air conditioning static pressure box made of an iron plate, fixing may be performed by a method such as screw fixing.
Further, the ceiling structure as the installation position of the static pressure box 20 for air conditioning is not limited to the grid ceiling 10, and therefore the static pressure box 20 for air conditioning can be installed on the system ceiling in which the ceiling is configured by arranging the T-shaped runners 11 in a linear shape.
On the other hand, the casing of the plenum box for an air conditioner may be composed of a frame member that can be assembled and disassembled, and a cover member that covers the entire frame member from the outer surface, in addition to the aforementioned portions. In this case, the covering member of the frame member is preferably made of a flexible cloth-like material, and for example, a non-combustible cloth such as canvas cloth or steel wool cloth, or synthetic fibers can be used. With such a configuration, the frame member, the covering member, and the like can be carried into the construction site, and the assembling operation of the plenum box for air conditioning can be performed on site, so that not only the transportability to the construction site is improved, but also a lightweight plenum box for air conditioning can be configured.
The static pressure box installation structure for air conditioners 100 and the like described with reference to fig. 1 to 8 are structures showing an example of the static pressure box installation structure for air conditioners of the present invention, and the static pressure box installation structure for air conditioners of the present invention is not limited to the static pressure box installation structure for air conditioners 100 and the like described above.
