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-mentioned problems, the present invention provides a fixing member for a ceiling mounting member, which is integrally formed with a hanging member inserting / mounting cylinder on a vertical surface of a fixing plate that is fastened to a beam member.

[0007] Furthermore, the fixed plate portions that are fastened to the beam members are vertically arranged, and the vertical surfaces of both plate portions are formed in different directions at right angles, and at least one vertical surface is provided with a hanging metal fitting insertion tubular body. It is also characterized in that it is integrally formed as a fixing member for a ceiling mounting member.

In any of the above cases, it is preferable that the hanging metal fitting insertion cylinder is formed by bending one end of a vertical surface.

Furthermore, according to the present invention, the fixed plate portions that are fastened to the beam are vertically arranged, and at the same time, the vertical surfaces of both plate portions are formed in different directions at right angles, and at least one vertical surface is suspended. A ceiling mounting member fixing bracket having a structure in which a metal fitting inserting cylinder is integrally formed, and at the intersection of vertically crossing beam members, an upper and lower fixing plate portion and an upper and lower beam member portion of the fixing metal member. For a ceiling-mounted member in which the above-mentioned hanging metal fitting insertion cylinder is formed on the side of the other vertical surface of the fixed plate and on the side of the other beam. It is characterized by the structure of the fixed part.

[0010]

[Action]

 By fixing the fixing plate to the beam, for example, by fixing the fixing plate with bolts or bolts and nuts, the hanging metal fitting can be inserted into the hanging metal fitting insertion cylinder that is formed on the vertical surface of the fixing plate. The member may be suspended.

[0011]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an example of a ceiling mounting member fixing metal fitting 1 and its fixing portion which are fixed to one beam member, and FIGS. An example of a ceiling mounting member fixing bracket 11 for connecting beam members of a book and its fixing portion is shown. The beam member is appropriately suspended by means of a slab (ceiling or floor slab) or is joined to another column member or the like, and is shown as a C-shaped channel member 10 in each embodiment.

In FIGS. 1 and 2, the fixing member 1 is configured by combining a fixing plate 2 and a receiving plate 8. The fixing plate 2 has a bolt insertion hole 4 formed in a vertical surface 3 of a C-shaped body to be fitted on the opening side surface and the upper and lower surfaces of the C-shaped channel member 10, and extends the vertical surface to one side. The extension metal portion is wound on the outside to form a cylindrical hanging metal fitting insertion and attachment tubular body 5 which is integrally formed at one end of the vertical surface 3, and the upper surface 6 of the U-shape is defined as the vertical surface 3. When they are formed to have substantially the same width or more, a notch 7 is previously formed between the vertical surface 3 portion where the tubular body 5 is formed and the upper surface 6 portion so that the tubular body 5 can be easily formed. Should be formed.

The receiving plate 8 is formed as a U-shaped body having a cross section capable of sandwiching the C-shaped channel material 10 together with the fixed plate 2 while substantially abutting the inside of the C-shaped channel material 10 fitted with the fixed plate 2. A bolt receiving hole 9 is formed on the vertical surface.

The receiving plate 8 has a vertical length in the vertical direction which is substantially close to or matches the inner vertical spacing of the C-shaped channel material 10, and at the same time, the diagonal portions of the upper and lower portions of the receiving plate 8 are preferably set to the respective vertical positions. Approximately half of the upper and lower sides are cut out in an arc shape or a taper shape to form a cutout portion 8a, and a U-shaped cross section is formed vertically from the upper and lower side portions other than the cutout portion 8a, and the bolt receiving hole 9 is formed as a female screw hole. Is preferred.

Thus, the fixed portion of the ceiling mounting member is such that the fixed plate 2 is placed outside the C-shaped channel material 10 and the receiving plate 8 is placed inside and the C-shaped channel material 10 is sandwiched between the two plates 2 and 8. The bolt is inserted into the bolt insertion hole 4, the C-shaped opening, and the bolt receiving hole 9 from the outside, and is fixed by tightening.

According to the receiving plate 8 described above, when the receiving plate 8 is tightened with a bolt, the receiving plate 8 rotates as the bolt rotates, and the horizontal upper and lower sides of the C-shaped channel member 10 pass through the notches 8a. Since the inner upper and lower surfaces are abutted and locked, the tightening work can be extremely easy and efficient.

However, the receiving plate 8 may be formed as a simple U-shaped receiving plate without forming the above-mentioned notch 8a. In this case, the bolt receiving hole 9 is not a female screw hole. Instead, it may be formed as a simple insertion hole through which the bolt is inserted and tightened with a bolt nut.

The tubular body 5 may be formed by factory welding a separately molded tubular body to the vertical surface 3, but one side of the vertical surface 3 is bent to form a cylindrical shape. However, there are advantages that the manufacturing process is simplified and the strength is increased.

The tubular body 5 may be formed as a simple tubular body into which a suspending metal fitting is inserted. In this case, the inserted suspending metal fitting is fastened with a nut on the upper side of the tubular body 5. If the inner surface of the cylindrical body 5 is cut, the bolt portion of the hanging metal fitting can be directly screwed onto the cylindrical body.

Further, an example is shown in which one bolt insertion hole 4 and one bolt receiving hole 9 are formed on each of the vertical surface 3 and the vertical surface of the receiving plate 8, but any two or more holes should be formed. You can

Each of the above-mentioned modified examples, that is, the presence or absence of the cutout portion 8 of the receiving plate, the presence or absence of the female screw of the bolt receiving hole 9, the forming method of the tubular body 5 and the presence or absence of the female screw forming of the inner surface, the bolt insertion hole and the receiving hole. The number and other modifications are all included in the present invention, and this structure is similarly applicable to other embodiments described later.

Next, referring to FIGS. 3 and 4, the fixing plate 11 is made up of fixing plate portions 12 a and 12 b, which are fixed to the C-shaped channel members 10 and 10 intersecting with each other in the vertical direction. And receiving plates 18a and 18b combined with these fixed plate portions 12a and 12b.

The fixed plate portion 12a is a U-shaped body having a U-shaped cross section, which is fitted to the opening side surface and the upper and lower surfaces of the lower C-shaped channel material 10 among the intersecting C-shaped channel materials 10, 10. A bolt insertion hole 14a is bored in the vertical surface 13a, and an extension surface portion obtained by extending the vertical surface to one side is wound on the outside to form a hanging metal fitting insertion cylinder 15a, which has a cylindrical shape, on the vertical surface 13a. It is integrally formed at one end, and the tubular body 15a is previously formed between the vertical surface 13a portion where the tubular body 15a is formed and the U-shaped upper surface 16a portion so that the tubular body 15a can be easily formed. It is preferable to form the cutout portion 17a.

The U-shaped upper surface 16a is formed to have a width such that it extends slightly laterally beyond the position of the cylindrical body 15a of the vertical surface 13a. A vertical surface 13b is formed which abuts the opening side surface of the C-shaped channel material 10 located on one side, and a bolt insertion hole 14b is bored in the vertical surface 13b to form the fixed plate portion 12b. Therefore, the vertical surface 13a and the vertical surface 13b are formed at different vertical positions so as to face each other at right angles.

The receiving plate 18a substantially comes into contact with the inner side of the lower C-shaped channel material 10 in which the fixed plate portion 12a is fitted, and at the same time, has a cross-sectional shape that sandwiches the C-shaped channel material 10 together with the fixed plate portion 12a. It is formed in a V shape, and a bolt receiving hole 19a is formed in the vertical surface thereof, and the receiving plate 18b is formed in a U shape in cross section for sandwiching the upper C-shaped channel material 10 in the same manner as described above. A bolt receiving hole 19b is provided.

The fixed portion of the ceiling mounting member in the intersecting C-shaped channel members 10 and 10 has the fixed plate portion 12a on the outside of the lower C-shaped channel member 10 and the receiving plate 18a on the inside. Both plates 12a and 18a are sandwiched between the C-shaped channel members 10, and the C-shaped opening is used to temporarily fix both plates with bolts through the bolt insertion hole 14a and the bolt receiving hole 19a, while fixing the upper part. The plate portion 12b is on the outside of the upper C-shaped channel material 10, the receiving plate 18b is on the inner side, and both plates 12b and 18b are sandwiched between the C-shaped channel material 10 and tightened with bolts in the same manner as described above. The above temporary fixing is tightly tightened and fixed. The upper and lower two C-shaped channel members 10, 10 are joined and fixed by the fixing fittings 11, and can also serve as a erection fixing means for the channel members.

In the construction procedure, first, the lower fixed plate portion 12a is fitted onto the lower C-shaped channel material 10, while the upper fixed plate portion 12b and the receiving plate 18b are attached to the upper C-shaped channel material 10. It goes without saying that the fixing plate portion 12a can be fixed to the receiving plate 18a and then the receiving plate 18a can be fixed to the fixing plate portion 12a.

In any of the above-mentioned examples, since the tubular body 5 and the tubular body 15a are disposed with their upper and lower positions deviated from the C-shaped channel material 10, the upper surfaces 6 and 16a, and the fixed plate portion 12b, FIG. As described above, it is easy to insert the hanging metal fitting into the cylindrical body 5 or 15a or to tighten the nut on the hanging metal fitting so that the work is not hindered.

FIG. 6 shows a modified example of the cylindrical bodies 5 and 15a of the above-described embodiments. In this, the nut mounting gap 20 is formed by cutting the vertical portion of the intermediate portion of the tubular portion and its vicinity. A nut 22 may be arranged in the gap 20 and the hanging metal fitting 21 may be screwed and inserted into the tubular body 5 (15a). According to this configuration, the length of the hanging fitting can be adjusted more sufficiently and more easily.

According to the above configuration, the fixing brackets 1 and 11 can be manufactured in a factory, and at the construction site, it is sufficient to fix the fixing bracket with a bolt or a nut with a C-shaped channel material at a predetermined location. After that, the air conditioner can be installed easily by inserting the hanging metal fittings into the tubular bodies 5 and 15a of the fixing metal fittings. The suspension using the fixing fittings is not limited to the air conditioning equipment, and ceiling materials and any other ceiling mounted members can be suspended.

[0032]

[Effect of the device]

 As described above, according to the present invention, it is possible to provide a ceiling mounting member fixing bracket that does not need to be processed in the field, has a simple and strong form, and can be fixed by a simple operation only by tightening. Since the hanging metal fitting inserting cylinder formed integrally with this fixing metal fitting can be provided as having a sufficient length, the hanging metal fitting to be inserted does not shake and the length can be increased. Adjustments may also be possible.

In the case of suspending a comparatively lightweight object, a fixing metal fitting in which a hanging metal fitting inserting cylinder is integrally formed on a vertical surface of a fixing plate which is fastened to one beam can be suitably used, When suspending a comparatively heavy object, the fixed plate parts that connect and fasten the intersecting beam members are connected vertically, and the vertical surfaces of both plate parts are formed in different right-angled directions. At least, a fixing metal fitting, which is integrally formed with a hanging metal fitting inserting cylinder on one vertical surface, can be preferably used.

The tubular body is formed by bending one end on one side of the vertical surface, whereby the manufacturing and use strength of the fixing fitting can be further rationalized and improved. Further, the construction of the fixed portion of the ceiling mounting member is rationalized as described above.
