Generally, this type of air conditioning component is installed above or below the ceiling of a building. For example, multiple hanging members made of fully threaded screws are suspended from the ceiling material. A support beam is suspended between the lower ends of two pairs of these hanging members. Multiple hanging frames, each consisting of two hanging members and a support beam, are arranged at intervals in a direction perpendicular to the support beam. Air conditioning components are placed on the support beams of each hanging frame so as to be suspended across the multiple hanging frames. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-134960 Summary of the Invention [Problem to be solved by the invention]

[0004] Assembling a plurality of suspension frames, each consisting of a suspension member and a support beam, in a building ceiling is complicated and time-consuming, which makes the installation of air conditioning components take a long time. In view of the above circumstances, the present invention aims to provide an air conditioning support device that allows air conditioning components to be easily installed on the ceiling of a building and reduces the installation time. [Means for solving the problem]

[0005] In order to solve the above problems, the present invention provides a device for connecting and supporting an air conditioning member having a rectangular cross section made of foamed resin to a hanging material having a full screw, a connecting fitting including an L-shaped angle part having a horizontal piece and a vertical piece and attached to a corner of the air conditioning member, an insertion claw protruding from the horizontal piece of the angle part parallel to the vertical piece and inserted into the air conditioning member, and a connecting protrusion protruding horizontally from the vertical piece to the opposite side from the horizontal piece and placed on a receiving nut screwed onto the hanging material; The connecting projection has a notch formed therein, and the notch has a guide opening that reaches the edge of the connecting projection and can receive the hanging material. The air conditioning support structure according to the present invention includes an air conditioning member having a rectangular cross section and made of foamed resin; a connecting fitting for connecting and supporting the air conditioning member to a hanging material having a full thread; The connecting fitting is The air conditioning member includes an L-shaped angle portion having a horizontal piece and a vertical piece and attached to a corner of the air conditioning member, an insertion claw protruding from the horizontal piece of the angle portion parallel to the vertical piece and inserted into the air conditioning member, and a connecting protrusion protruding horizontally from the vertical piece to the opposite side of the horizontal piece, a notch hole is formed in the connecting protrusion, and the notch hole has a guide opening that reaches an edge of the connecting protrusion; The hanging member is received in the notched hole through the guide opening, and the connecting protrusion is placed on a receiving nut that is screwed onto the hanging member.

[0006] When installing the air conditioning component, a receiving nut is attached to the fully threaded hanging member in advance. Then, the connecting fitting is brought close to the hanging member from the side, and the hanging member is inserted from the side into the cutout hole through the guide opening of the connecting protrusion. The connecting protrusion is placed on the receiving nut, thereby supporting the connecting fitting on the hanging member. Around the same time, the corner of the air conditioning component is aligned with the angle portion, and the insertion claw is inserted into the air conditioning component. This allows the air conditioning component to be suspended and supported by the hanging member via the connecting fitting and receiving nut. The work of attaching the connecting fitting to the hanging member and the work of connecting the air conditioning component to the connecting fitting are both simple and can be completed in a short time. Therefore, according to the present invention, construction time can be significantly reduced compared to conventional support structures using a hanging frame including support beams (see Patent Document 1, etc.).

[0007] It is preferable that the connecting fittings are arranged at the upper and lower corners of the air conditioning component, and that the connecting fittings at the upper corners have the insertion claws protruding downward from the horizontal piece of the angle portion, and that the connecting fittings at the lower corners have the insertion claws protruding upward from the horizontal piece of the angle portion. The lower connecting fittings can support the weight of the air conditioning components, while the upper connecting fittings can hold down the air conditioning components from above, preventing the air conditioning components from coming loose from the connecting fittings' insertion tabs even when subjected to vibrations such as those caused by an earthquake, and maintaining the support state of the air conditioning components.

[0008] It is preferable that a pair of locking claws protruding downward are formed on both sides of the guide opening at the edge of the connecting projection. The locking claw can lock the receiving nut, preventing the connecting fitting from coming off the hanging material.

[0009] The angle portion of the connecting fitting is provided with, as the insertion claws, large insertion claws having a protruding length greater than the wall thickness of the air conditioning member and small insertion claws having a protruding length less than the wall thickness of the air conditioning member, which are parallel to each other, The large insertion claw is inserted into the vertical wall of the corner of the air conditioning member, It is preferable that the small insertion claws are inserted into the side walls of the corners of the air conditioning member. This allows the large insertion claws to be embedded inside the vertical walls (side panels) of the air conditioning component, and the small insertion claws to be embedded inside the horizontal walls of the air conditioning component, preventing the tips of the small insertion claws from penetrating the horizontal walls and protruding into the interior of the air conditioning component. In the lower connecting fitting, the side wall into which the small insertion claws are inserted is the bottom plate of the air conditioning member. In the upper connecting fitting, the side wall into which the small insertion claws are inserted is the top plate of the air conditioning member. [Effects of the Invention]

[0010] According to the present invention, air conditioning components can be easily installed on the ceiling of a building, and installation time can be reduced. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in Fig. 1, an air conditioning support structure 1 in an air conditioning facility includes a mixing chamber 10 (air conditioning member) to be supported, and an air conditioning support device 3. As shown in Figs. 1 and 2, the mixing chamber 10 is formed in the shape of a long box with a rectangular cross section. A conditioned air inlet 41 and an outside air inlet 42 are provided on both longitudinal side walls 12 of the mixing chamber 10, an outlet 43 is provided on an end wall 14, and a partition wall 15 is provided inside. The mixing chamber 10 has the function of taking in conditioned air from an air conditioner (not shown) and outside air, and mixing them while sending them out.

[0013] As shown in Fig. 1, the wall material (the material of walls 11 to 15) of the mixing chamber 10 is made of a foamed resin board 10a covered on both sides with aluminum cloth sheets (not shown). The foamed resin board 10a is self-supporting and has shape-retaining properties. The resin component of the foamed resin board 10a is, for example, polyisocyanurate, which has excellent heat insulating properties, but is not limited to this and may also be polystyrene, polyolefin, polyurethane, phenol, etc.

[0014] The mixing chamber 10 is supported by an air conditioning support device 3 as follows. As shown in Figures 1 and 2, multiple hanging members 2, each made of a fully threaded screw, are suspended from the ceiling of a building. Two connecting metal fittings 20, 30, one above the other, are attached to each hanging member 2. The mixing chamber 10 is connected to and supported by the hanging members 2 via these connecting metal fittings 20, 30.

[0015] As shown in Figure 3(a), the upper connecting fitting 20 includes an angle portion 21, large and small insertion claws 24, 25, and a connecting projection 26. The angle portion 21 has a horizontal piece 22 and a vertical piece 23 that is perpendicular to the horizontal piece 22, and is formed in an L-shaped plate shape. The vertical piece 23 extends vertically downward from the horizontal piece 22.

[0016] Large and small insertion claws 24, 25 are provided on the horizontal piece 22. These large and small insertion claws 24, 25 are each formed as an elongated plate facing parallel to the vertical piece 23 and protruding vertically downward from the horizontal piece 22. The tip of each insertion claw 24, 25 is tapered, with the width gradually decreasing as it extends downward. The large and small insertion claws 24, 25 are parallel to each other.

[0017] 3(a) and 4, the length by which the large insertion claws 24 protrude downward from the horizontal piece 22 is greater than the length by which the small insertion claws 25 protrude and is greater than the wall thickness of the top plate 11 of the mixing chamber 10. On the other hand, the length by which the small insertion claws 25 protrude is less than the wall thickness of the top plate 11 of the mixing chamber 10.

[0018] The large insertion claw 24 is disposed closer to the vertical piece 23 than the small insertion claw 25. The distance between the large insertion claw 24 and the vertical piece 23 is smaller than the wall thickness of the long side wall 12 of the mixing chamber 10, and preferably about half the wall thickness of the long side wall 12. The distance between the small insertion claw 25 and the vertical piece 23 is greater than the wall thickness of the long side wall 12.

[0019] As shown in FIG. 3(a), a connecting projection 26 is connected to the lower end of the vertical piece 23. The connecting projection 26 is perpendicular to the vertical piece 23 and protrudes horizontally opposite the horizontal piece 22. A notch hole 26a is formed in the connecting projection 26. The notch hole 26a extends in the connecting projection 26 opposite the vertical piece 23 and reaches an edge 26e on the opposite side. A guide opening 26c for the notch hole 26a is formed in the edge 26e of the connecting projection 26. The width of the guide opening 26c and the diameter of the notch hole 26a are larger than the diameter (thread diameter) of the hanging material 2. Therefore, the hanging material 2 can be received in the notch hole 26a from the side of the connecting projection 26 through the guide opening 26c. A pair of locking claws 27 are formed on both sides of the guide opening 26c at the edge 26e of the connecting projection 26. These locking claws 27 protrude downward from the connecting projections 26 .

[0020] As shown in Figures 1 and 2, the upper connecting fitting 20 is disposed at the upper corner 16 formed by the long side wall 12 and the top plate 11 of the mixing chamber 10. As shown in Figure 4, the angle portion 21 is positioned at the corner 16, and the insertion claws 24, 25 are inserted into the corner 16. More specifically, the large insertion claw 24 is inserted into the upper part of the long side wall 12 (vertical wall). The small insertion claw 25 is inserted into the top plate 11 (horizontal wall). Both insertion claws 24, 25 are embedded within the wall of the mixing chamber 10 and do not protrude into the internal space of the mixing chamber 10.

[0021] As shown in Figure 4, hanging material 2 is passed through cutout hole 26a. Nuts 51 and 52 are screwed onto the middle portion of hanging material 2. Connecting piece 26 is placed on lower receiving nut 52 and is pressed down from above by upper holding nut 51. Connecting piece 26 is clamped between these nuts 51 and 52. Locking claw 27 is locked with receiving nut 52.

[0022] As shown in Figure 3(b), the lower connecting fitting 30 includes an angle portion 31, large and small insertion claws 34, 35, and a connecting projection 36. The angle portion 31 has a horizontal piece 32 and a vertical piece 33 that is perpendicular to the horizontal piece 32, and is formed in an L-shaped plate shape. The vertical piece 33 extends vertically upward from the horizontal piece 32.

[0023] Large and small insertion claws 34, 35 are provided on the horizontal piece 32. These large and small insertion claws 34, 35 are each formed as an elongated plate facing parallel to the vertical piece 33 and protruding vertically upward from the horizontal piece 32. The tip of each insertion claw 34, 35 is tapered, with the width gradually decreasing as it extends upward. The large and small insertion claws 34, 35 are parallel to each other.

[0024] 3(b) and 5, the protruding length of the large insertion claw 34 is greater than the protruding length of the small insertion claw 35 and is greater than the wall thickness of the bottom plate 13 of the mixing chamber 10. On the other hand, the protruding length of the small insertion claw 35 is less than the wall thickness of the bottom plate 13 of the mixing chamber 10.

[0025] The large insertion claw 34 is disposed closer to the vertical piece 33 than the small insertion claw 35. The distance between the large insertion claw 34 and the vertical piece 33 is smaller than the wall thickness of the long side wall 12 of the mixing chamber 10, and preferably about half the wall thickness of the long side wall 12. The distance between the small insertion claw 35 and the vertical piece 33 is greater than the wall thickness of the long side wall 12.

[0026] As shown in FIG. 3(b), a connecting projection 36 is connected to the upper end of the vertical piece 33. The connecting projection 36 is perpendicular to the vertical piece 33 and protrudes horizontally opposite the horizontal piece 32. A notch 36a is formed in the connecting projection 36. The notch 36a extends in the connecting projection 36 opposite the vertical piece 33 and reaches the edge 36e on the opposite side. A guide opening 36c for the notch 36a is formed in the edge 36e of the connecting projection 36. The width of the guide opening 36c and the diameter of the notch 36a are larger than the diameter (thread diameter) of the hanging material 3. Therefore, the hanging material 2 can be received in the notch 36a from the side of the connecting projection 36 through the guide opening 36c. A pair of locking claws 37 are formed on both sides of the guide opening 36c at the edge 36e of the connecting projection 36. These locking claws 37 protrude downward from the connecting projections 36 .

[0027] As shown in Figures 1 and 2, the lower connecting fitting 30 is disposed at the lower corner 17 formed by the long side wall 12 and bottom plate 13 of the mixing chamber 10. As shown in Figure 5, the angled portion 31 is positioned at the corner 17, and the insertion claws 34, 35 are inserted into the corner 17. More specifically, the large insertion claw 34 is inserted into the lower portion of the long side wall 12 (vertical wall). The small insertion claw 35 is inserted into the bottom plate 13 (horizontal wall). Both insertion claws 34, 35 are embedded within the wall of the mixing chamber 10 and do not protrude into the internal space of the mixing chamber 10.

[0028] As shown in Figure 5, the hanging material 2 is passed through the cutout hole 36a. Nuts 53 and 54 are screwed onto the lower end of the hanging material 2. The connecting projection 36 is placed on the lower receiving nut 54 and is pressed down from above by the upper holding nut 53. The connecting projection 36 is clamped between these nuts 53 and 54. The locking claw 37 is locked with the receiving nut 54.

[0029] The mixing chamber 10 is installed in the ceiling of a building as follows. Nuts 51 to 54 are screwed onto the hanging member 2, which is a fully threaded member, in advance. The lower connecting fitting 30 is brought close to the hanging member 2 from the side thereof, and the lower end of the hanging member 2 is inserted through the guide opening 36c into the notched hole 36a. Then, the connecting piece 36 is placed on the receiving nut 54. The locking claw 37 is caught on the receiving nut 54, preventing the connecting fitting 30 from coming off the hanging member 2. Next, the lower corner 17 of the mixing chamber 10 is placed against the angle portion 31, and the insertion claws 34, 35 are inserted into the walls 12, 13. This allows the mixing chamber 10 to be suspended from the hanging member 2 via the connecting fitting 30. The connecting fitting 30 is able to support the weight of the mixing chamber 10. The insertion claws 34, 35 are embedded in the walls 12, 13 and do not protrude into the air flow path of the mixing chamber 10, preventing heat in the air flow path from escaping through the connecting fitting 30 and ensuring thermal insulation. Furthermore, the connecting projection 36 is raised and lowered by the receiving nut 54, and the height and horizontality of the mixing chamber 10 are adjusted. Thereafter, the connecting projection 36 is tightly clamped by the holding nut 53 and the receiving nut 54. In this way, the mixing chamber 10 is fixed to the hanging member 2 via the connecting fitting 30.

[0030] Next, the upper connecting fitting 20 is brought closer to the hanging material 2 from the side thereof, and the middle portion of the hanging material 2 is inserted through the guide opening 26c into the notched hole 26a. Then, the connecting piece 26 is placed on the receiving nut 52. The locking claw 27 is caught on the receiving nut 52, preventing the connecting fitting 20 from coming off the hanging material 2. At the same time, the angle portion 21 is placed against the upper corner 16 of the mixing chamber 10, and the insertion claws 24, 25 are inserted into the wall materials 12, 11. The insertion claws 24, 25 are embedded in the walls 12, 11 and do not protrude into the air flow path of the mixing chamber 10, so heat in the air flow path is prevented from escaping through the connecting fitting 20, ensuring thermal insulation. Furthermore, by clamping the connecting protrusions 26 with nuts 51 and 52, the connecting fitting 20 is fixed to the hanging material 2. This allows the mixing chamber 10 to be pressed from above by the connecting fitting 20. Even if vibrations caused by an earthquake or the like are applied, the mixing chamber 10 can be prevented from coming off the insertion claws 24, 25, 34, and 35 of the connecting fittings 20 and 30, and the supported state of the mixing chamber 10 can be maintained.

[0031] The construction procedure can be modified as needed. The connecting fittings 20, 30 can be attached to the mixing chamber 10 by first inserting the insertion claws 24, 25, 34, 35 of the connecting fittings 20, 30 into the corners 16, 17 of the mixing chamber 10, and then the connecting fittings 20, 30 can be fixed to the hanging material 2. This increases the degree of freedom in construction.

[0032] The work of attaching the connecting fittings 20 to the hanging material 2 and the work of connecting the mixing chamber 10 to the connecting fittings 20 are both simple tasks that can be completed in a short time. Therefore, with the air-conditioning support structure 1, construction time can be significantly reduced compared to a conventional support structure using a hanging frame (see Patent Document 1, etc.).

[0033] The present invention is not limited to the embodiments, and various modifications can be made within the scope of the invention. For example, of the upper and lower connecting fittings 20, 30, the upper connecting fitting 20 may be omitted, and the air conditioning support device 3 may be composed of only the lower connecting fitting 30. Alternatively, of the upper and lower connecting fittings 20, 30, the lower connecting fitting 30 may be omitted, and instead the air conditioning member may be supported from below by another supporting means. The air conditioning member is not limited to the mixing chamber 10, but may be a distribution chamber or an air conditioning duct. [Industrial Applicability]

[0034] The present invention can be applied to construction techniques for installing air conditioning components such as air conditioning chambers (mixing chambers, distribution chambers, etc.) and air conditioning ducts in buildings. [Explanation of symbols]
