Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixture for a ceiling mounting member such as a ceiling air conditioner or the like, which is suspended from a beam member such as a lightweight steel frame fixed to a ceiling slab of a building, and a structure of a fixing portion thereof.

[0002]

[Prior Art]

 The air-conditioning system for buildings was to supply air-conditioning air by piping an air-conditioning duct to each outlet inside a heat exchanger installed centrally on the roof of a building, etc. Since it was difficult to arbitrarily set the temperature, flow rate, operation cut-off, etc. for each outlet, problems such as overcooling and insufficient cooling caused by differences in installation location and environmental conditions could not be solved. .

In response to this, recently, a system has been adopted in which air conditioners are independently installed for each room or each outlet. This is a fairly heavy air-conditioning unit, which is configured as a so-called fan coil unit in which a heat source and a blower are set behind the air outlet, and is arranged so that both lower surfaces are aligned with a predetermined air outlet on the ceiling surface. It is installed by suspending it on a C-shaped channel material which is crossed over the ceiling.

[0004]

[Problems to be solved by the device]

 However, in this system, while the C-shaped channel material is erected by a lightweight steel frame construction shop, a scaffold for welding is also installed to fix the C-shaped channel material by welding, and then the welding work welds and fixes the crossing channel. In addition, the suspension bolt support for suspending the air conditioning unit is welded and fixed to the C-shaped channel, and then the air conditioning unit is installed by the suspension bolt using the support. However, both workability and proficiency were required, and the burden on the work was considerable.

The present invention focuses on such a problem, and adopts a welding means in a system in which an air conditioning unit is arranged for each outlet, and a construction work for an aerial part is performed without requiring skill. It is a system that can be easily performed.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a locking seat having a locking hole through which a hanging metal fitting for suspending a ceiling mounting member can be inserted and a nut screwed to the hanging metal fitting can be locked. A ceiling mounting member fixing fixture, comprising at least an upright portion standing upright from the locking seat and a fixed seat folded back from the upright portion toward the locking seat forming side with a predetermined gap. To do.

In the above, it is preferable to form a nut rotation preventing protrusion around the upper surface side of the locking hole. Further, it is preferable that the locking hole is formed as a cutout hole including the central portion of the fixed seat and opening toward the standing portion.

Further, the fixed seat is vertically opposed to a vertical fixed seat which is hung with a predetermined gap between the fixed seat and the lower end of the vertical fixed seat, and is horizontally faced above the locking seat. It is preferably constituted by a horizontal fixed seat.

[0009]

[Action]

 The gap between the upright portion and the fixed seat is hooked on the side surface of the beam to bring the fixed seat into contact with the inner surface of the beam, and the ceiling mounting member is suspended in the locking hole of the locking seat. The hanging metal fitting of the ceiling mounting member is fixed by inserting the upper part of the metal fitting and screwing the nut to lock the nut to the locking seat. The length of the hanging fitting can be adjusted by rotating the nut.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The fixing metal fitting 1 shown in the drawing can be easily manufactured by pressing a rectangular metal plate, but the structure of the present invention is not limited by the manufacturing method. Further, the beam member will be described below as a C-shaped channel member.

The fixing metal fitting 1 has a horizontal plate-shaped locking seat 2 at its lower end, and a vertical plate-shaped standing portion 3 is formed by bending from one end of this locking seat 2 from the upper end of the standing portion 3. A drooping plate-like hanging fixing seat 5a folded back with a predetermined gap 4 is formed, and is further horizontally bent from the tip of the fixing seat to horizontally face a horizontal plate fixed above the locking seat. A seat 5b is formed, and the vertical fixed seat 5a and the horizontal fixed seat 5b form a fixed seat 5. The interval between the locking seat 2 and the horizontal fixed seat 5b allows the vertical length of the hanging metal fitting 10 to be adjusted. As described above, it is set with an appropriate distance maintained, and the whole is bent and formed in this way.

Further, the locking seat 2 is formed with a locking hole 6 as a notch hole which is open to the vertical surface 3 side including the central portion thereof, and the vertical surface 3 is provided with the locking hole 6. 6, a notch hole 7 having a size that allows the hanging metal fitting 10 and the nut 11 to be screwed to the hanging metal fitting 6 to be inserted, preferably approximately the height of the horizontal fixing seat 5b, is formed. 2 Around the locking hole 6 on the upper surface, a projection 8 is formed around the locking hole 6 for preventing the nut 11 from rotating and coming off to the side. The vertical fixing seat 5a projects into the gap 4 between the vertical surfaces 3. Moreover, an appropriate number of protrusions 9 capable of sandwiching the side surface portion of the channel material 12 by the vertical surface 3 are formed.

In the above description, the projection 8 can be formed by bending the locking seat 2, but can be formed by welding a separate molded product. Further, instead of the protrusion 9, bolt holes are bored only in the vertical fixing seat 5a or through the vertical fixing seat 5a and the vertical surface 3, and the channel member 12 is fixed with bolts or bolt nuts. be able to.

According to the fixing member 1, the fixing seat 5 is hooked on the channel member 12 by fitting the side surface of the channel member 12 into the gap 4, and the vertical fixing seat 5a and the horizontal fixing seat 5b are both attached to the channel. Fix it by abutting against the inner surface of the material 12, and then disposing the nut 11 on the upper side of the locking seat 2 and passing the upper part of the hanging metal fitting 10 through the locking hole 6 to screw the nut 11 into place. For example, the nut 11 is locked to the locking seat 2, and the hanging metal fitting 10 is suspended on the fixing metal fitting 1.

By adjusting the screwing state of the hanging metal fitting 10 and the nut 11, the length of the hanging metal fitting 10 can be adjusted by an amount corresponding to the length within the interval between the horizontal fixed seat 5 b and the locking seat 2. On the other hand, the nut 11 is prevented from rotating by the projection 8 and does not come off.

Further, since the locking seat 2 supporting the hanging metal fitting 10 is located below the channel member, more particularly, the horizontal fixing seat 5b and the locking seat 2 are vertically opposed to each other. Since the center of gravity and the fulcrum of the hanging metal fitting substantially coincide with each other in the plane, a strong torsion pressure is not generated and the suspended state is stable, which is preferable. The suspension using the suspension metal fittings is not limited to air-conditioning equipment, and it is possible to suspend ceiling materials and any other ceiling mounted members.

[0017]

[Effect of the device]

 As described above, according to the present invention, there is provided a fixture for a ceiling-mounted member, which does not need to be processed on-site, has a simple and strong form, and can be fixed by a simple operation of just latching. It is possible to suspend the hanging metal fitting by inserting the hanging metal fitting into the locking hole formed in this fixing metal fitting and screwing the nut into it. Therefore, the ceiling mounting member using the hanging metal fitting can be suspended. The installation work of is extremely simple and a stable suspended state can be obtained. In particular, if the fixed seat portion and the locking seat are formed so as to face each other, the load can be caught near the center of gravity, so that the fixing stability is good.
