Description

  The present invention relates to a heavy-weight attachment structure for attaching heavy objects such as hanging walls, balustrades, and upper hanging doors that are suspended from a ceiling portion to a horizontal member on the back of the ceiling using a suspension fitting.

  Conventionally, it is known that a hanging wall suspended from a ceiling portion is attached to a beam behind the ceiling using a U-shaped hanging bracket (see, for example, Patent Document 1).

However, conventionally, the lower end portion of the U-shaped hanging bracket is inserted and fixed to the upper portion of the hanging wall, and the upper end portion of the U-shaped hanging bracket is bolted directly to the lower flange of the beam behind the ceiling. For this reason, it is necessary to drill a bolt hole in the lower flange of the beam, and it takes time and labor to attach the U-shaped hanging bracket, resulting in a decrease in work efficiency.

In addition, it is possible to increase the support strength of the horizontal member to be used horizontally, and to attach the hanging bracket to the horizontal member to be used very easily and firmly. It is an object of the present invention to provide a heavy load mounting structure.

  In order to solve the above-mentioned problem, in the invention according to claim 1, heavy objects 1 such as a hanging wall 1a suspended from the ceiling part, a balustrade, an upper suspension door, etc. In the heavy load attachment structure, the horizontal member 2 includes a wide long side wall 2a and a pair of narrow short side walls 2b, 2b orthogonal to the long side wall 2a and facing each other. The suspension metal fitting 3 is formed of a steel mold material, and includes a metal fitting body 3a externally fitted to the horizontal member 2, and a suspension bolt 3b whose lower part is fixed to the heavy object 1 and whose upper part is fixed to the metal fitting body 3a. The metal fitting body 3a includes a metal fitting back portion 3c facing the long side wall 2a of the horizontal member 2, and a pair of holding portions 3d that are held in close contact with the outer surfaces of the pair of short side walls 2b, 2b of the horizontal member 2. 3d, and at each tip of the pair of hold portions 3d and 3d A metal extension 3e extending longer than the tips of the pair of short side walls 2b and 2b is extended, and a first bolt hole 4 is formed in each metal extension 3e and a second bolt hole 5 is formed in each metal back 3c. The horizontal member 2 is vertically used so that the long side wall 2a is in the vertical direction, and the horizontal member 2 is in close contact with the horizontally used horizontal member 2 from the horizontal direction B by external fitting. In the state where the metal back 3c and the long side wall 2a of the horizontal member 2 are opposed to each other with a gap 7, the adjustment bolt 6 is tightened into the second bolt hole 5 of the metal back 3c. By pressing the long side wall 2a of the horizontal member 2 at the tip, the metal fitting body 3a is positioned in the horizontal direction B with respect to the horizontal member 2, and suspended from below in the first bolt hole 4 of the metal extension 3e. The bolt 3b is fastened and fixed.

  With this configuration, the load G of the heavy load 1 applied to the suspension bolt 3b is received by the entire horizontal member 2 through the metal fitting body 3a, and the long side wall 2a By adopting the vertical use in the vertical direction, the strength of the horizontal member 2 is greatly improved, and thereby the support strength of the hanging wall 1a can be increased. Moreover, since the suspension bolt 3b is fastened to the bracket body 3a while holding the horizontal member 2 in the bracket body 3a, a bolt hole is formed in the lower flange of the horizontal member (beam) as in the prior art. There is no need to drill holes. Further, since the holding portions 3d and 3d of the metal fitting body 3a are held in close contact with the short side walls 2b and 2b of the horizontal member 2, it becomes possible to prevent the metal fitting main body 3a from wobbling, and the adjustment bolt 6 allows the horizontal member to be held. Positioning of the hanging bracket 3 with respect to 2 in the horizontal direction B is facilitated. Moreover, by allowing the bracket back 3c and the long side wall 2a of the horizontal member 2 to face each other with a gap 7 therebetween, It is possible to easily cope with the dimensional tolerance between the two. As a result, the attachment of the hanging bracket 3 to the horizontal member 2 can be performed very easily and firmly.

  Further, in the invention according to claim 2, a heavy object 1 such as a hanging wall 1a suspended from a ceiling part, a balustrade, and an upper hanging door is attached to a horizontal member 2 on the back of the ceiling using a hanging metal fitting 3. In the mounting structure, the horizontal member 2 is constituted by a steel mold having a wide long side wall 2a and a pair of narrow short side walls 2b, 2b orthogonal to the long side wall 2a and facing each other. The hanging metal fitting 3 includes a metal fitting body 3a that is externally fitted to the horizontal member 2, a fixing bolt 8 that fixes the metal fitting body 3a to the horizontal member 2, a lower portion fixed to the heavy object 1, and an upper portion attached to the metal fitting body 3a. The bracket main body 3a is closely attached along the outer surface of the pair of short side walls 2b, 2b of the horizontal member 2 and the metal back 3c facing the long side wall 2a of the horizontal member 2. And holding a pair of holding portions 3d and 3d, The metal extension portions 3e extending longer than the tips of the pair of short side walls 2b, 2b are respectively extended at the tips of the first and second portions 3d, 3d. The second bolt holes 5 are respectively drilled in 3c, and the horizontal member 2 is used sideways with the long side wall 2a facing sideways, and the metal fitting body 3a is externally fitted from below the horizontal member 2 used sideways. Holding the horizontal member 2 in a close contact state and extending the metal member protruding upward from the horizontal member 2 with the metal back 3c and the tip of the short side wall 2b of the horizontal member 2 facing each other with a gap 7 therebetween. The fixing bolt 8 is inserted into the first bolt hole 4 of the portion 3e from the horizontal direction B, the upper surface of the horizontal member 2 is pressed and held from above by the fixing bolt 8, and the first bolt hole 4 of the metal back portion 3c. The suspension bolt 3b is fastened and fixed to the bottom from below.

  With such a configuration, the load G of the heavy load 1 applied to the suspension bolt 3b is received by the entire horizontal member 2 via the metal fitting body 3a and the fixing bolt 8, and the ceiling space is low, for example. Therefore, when the horizontal member 2 is used sideways, the strength of the horizontal member 2 used in the horizontal direction can be sufficiently secured by shortening the span between the beams that support both ends of the horizontal member 2. As a result, the supporting strength of the drooping wall 1a can be increased. Moreover, a method of fastening the suspension bolt 3b to the metal fitting body 3a while holding the horizontal member 2 by the metal fitting body 3a is adopted, and the fixing bolt 8 inserted through the first bolt hole 4 of the metal fitting extension 3e is used. Since the upper surface of the horizontal member 2 is pressed and held from above, the metal fitting body 3a can be easily positioned in the vertical direction A with respect to the horizontal member 2 and can be prevented from wobbling. Further, the metal back 3c and the horizontal member can be prevented. By facing the lower surface of 2 with a gap 7, the dimensional tolerance between the horizontal member 2 and the metal fitting body 3a can be easily handled. As a result, the attachment of the hanging bracket 3 to the horizontal member 2 can be performed very easily and firmly.

  In the present invention, it is possible to attach the hanging bracket to the horizontal member used in the vertical direction very easily and firmly, and the working efficiency can be greatly improved.

  In addition, in the present invention, it is possible to increase the support strength of the horizontal member to be used sideways, and to attach the hanging bracket to the horizontal member to be used sideways very easily and firmly. Efficiency can be greatly improved.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

An example in which both ends are supported by a lower flange 2d of a floor beam 2A on the second floor (hereinafter referred to as “floor beam”) is shown. In the example of FIG. 4, the adjacent floor beams 2A, 2A are present with a span of 4P pitch, so that the horizontal brace 9 for reinforcing the ceiling area of the first floor in the horizontal plane can be arranged as shown in FIG. In addition, a sufficient space S exists in the vertical direction A between the horizontal brace 9 and the lower flange 2d of the floor beam 2A, and the horizontal member 2 can be easily stored in the space S by being used vertically. . Note that F in FIG. 4 is a ceiling surface on the first floor. Hereinafter, an example in the case of attaching the heavy article 1 to the horizontal member 2 used vertically will be described.

  As shown in FIG. 1, the horizontal member 2 of this embodiment includes a wide long side wall 2a, a pair of short side walls 2b, 2b narrower than the long side wall 2a, and a pair of short side walls 2b, 2b. The pair of lip portions 2c at each end is formed of a lip groove steel having a vertically long cross section integrally formed. The horizontal member 2 is not limited to the lip groove type steel, but may be a C-type steel or a square steel pipe. In short, a mold having at least a wide long side wall 2a and a pair of narrow short side walls 2b, 2b. Any steel material may be used.

  In addition, the heavy object 1 is not limited to the hanging wall 1a (including a hanging door shelf) shown in FIG. In the case of the hanging wall 1a, the lower part of the suspension bolt 3b is passed through the upper frame 1c and fastened with a nut 1d to be fixed to the lower part of the suspension bolt 3b. Further, as shown in FIG. 4, the hanging wall 1 a is suspended and supported at a plurality of positions of the horizontal member 2 by using a plurality of hanging brackets 3.

  As shown in FIGS. 1 (a) and 1 (b), the hanging metal fitting 3 of the present embodiment includes a metal fitting body 3a attached to the horizontal member 2, and a hanging bolt 3b whose lower part is fixed to the hanging wall 1a. ing.

  The metal fitting body 3a is integrally formed with a metal fitting back portion 3c facing the long side wall 2a of the horizontal member 2, and a pair of holding portions 3d, 3d connected to both ends of the metal fitting back portion 3c. In the present embodiment, the inner dimension L1 between the pair of holding portions 3d, 3d is set to be substantially the same as the outer dimension L2 between the pair of short side walls 2b, 2b of the horizontal member 2, and FIG. ), The pair of short side walls 2b, 2b can be held between the pair of holding portions 3d, 3d.

  Further, a metal extension 3e extending longer than the tips of the short side walls 2b and 2b is extended at the tips of the pair of holding portions 3d and 3d, respectively, and the first bolt holes 4 are formed in the metal extensions 3e. Is drilled. The first bolt hole 4 has a hole shape through which the suspension bolt 3b can be slid. A second bolt hole 5 is formed in the metal back part 3c. A female screw into which the adjusting bolt 6 is screwed is engraved in the second bolt hole 5. Further, a screw hole 35 is formed in each of the pair of holding portions 3d and 3d, and a screw pilot hole facing the screw hole 35 is previously formed in the horizontal member 2. Then, by screwing the screw 10 through the screw hole 35, the metal fitting body 3a is moved in the horizontal direction B of the horizontal member 2 (the left-right direction in FIG. 1B and the depth direction perpendicular to the paper surface in FIG. 1B). ) So that the hanger 3 can be prevented from shifting in the horizontal direction B with respect to the horizontal member 2.

  Moreover, in this embodiment, the gap 7 is generated between the long side wall 2a of the horizontal member 2 and the metal back part 3c in a state where the lip 2c of the horizontal member 2 is abutted against the suspension bolt 3b. 7, the dimensional tolerance between the horizontal member 2 and the metal fitting body 3a can be easily accommodated. That is, the gap 7 is an adjustment allowance for adjusting the dimensional tolerance, and the bracket body 3a is positioned in the horizontal direction B with respect to the horizontal member 2 in a state where the gap 7 is provided by tightening the adjustment bolt 6. is there. Further, the adjustment bolt 6 is tightened and pressed against the horizontal member 2 with the tip of the adjustment bolt 6, thereby preventing the metal fitting body 3 a from wobbling against the horizontal member 2. For example, a hexagon bolt with a cross hole is used as the adjustment bolt 6.

  Next, when the hanging wall 1a is suspended from the horizontal member 2 that is used vertically, the metal fitting 3a is externally fitted to the horizontal member 2 that is used vertically from the horizontal direction B so that the horizontal member 2 is in close contact. Holding the metal back 3c and the long side wall 2a of the horizontal member 2 with the gap 7 facing each other, the adjustment bolt 6 is tightened from the second bolt hole 5 of the metal back 3c in this state. By pressing the long side wall 2a of the horizontal member 2 with the tip of 6, the metal fitting body 3a is positioned in the horizontal direction B (the direction of the gap 7) with respect to the horizontal member 2, and the screw 10 is attached to the metal fitting 3a. The metal fitting body 3a is fixed to the horizontal member 2 so as not to move in the horizontal direction B by tightening the screw holes 35 provided in the holding portions 3d and 3d into the screw pilot holes of the horizontal member 2. Thereafter, the upper part of the suspension bolt 3b is inserted into the first bolt holes 4 of the upper and lower metal fitting extensions 3e and 3e and fastened by the nuts 11 and 11 from above and below. Thereby, the attachment of the hanging bracket 3 to the horizontal member 2 is completed.

  Thus, the load G of the hanging wall 1a applied to the suspension bolt 3b can be received by the entire horizontal member 2 through the metal fitting body 3a, and the horizontal member 2 can be used vertically with the long side wall 2a oriented vertically. By doing, the intensity | strength of the horizontal member 2 improves significantly, and, thereby, the support strength of the drooping wall 1a can be raised. In addition, since the suspension bolt 3b is fastened to the metal body 3a with the nut 11 while the horizontal material 2 is held by the metal body 3a, the lower flange of the horizontal material (beam) is used as in the prior art. It is not necessary to drill a bolt hole, and the wobbling of the metal fitting body 3a can be prevented. Further, the adjustment bolt 6 makes it easy to position the hanging metal fitting 3 in the horizontal direction B with respect to the horizontal member 2. As a result, the attachment of the hanging bracket 3 to the horizontal member 2 can be performed very easily and firmly. Even if there is a dimensional tolerance between the horizontal member 2 and the metal fitting body 3a, a gap 7 (adjustment allowance) is provided between the long side wall 2a of the horizontal material 2 and the metal back portion 3c. The gap 7 can sufficiently cope with the dimensional tolerance, and the fitting main body 3a is attached to the horizontal member 2 even when the gap 7 shown in FIG. There is also an advantage that can be reliably positioned in the horizontal direction B.

  The horizontal member 2 is preferably used vertically as in the above embodiment in order to ensure strength. For example, as shown in FIG. 5, a floor beam 2C is arranged between floor beams 2B and 2B. When the floor beam 2B and the floor beam 2C are present at a 2P pitch as in the case where the center lower surface of the floor panel 19 on the second floor is supported by the floor beam 2C, the ceiling region is within the horizontal plane. 5, the horizontal brace 9 for reinforcement is only arranged as shown in FIG. 5. Therefore, a space S ′ in the vertical direction A between the horizontal brace 9 and the lower flange 2e of the floor beam 2B (> space S in FIG. 4). ) Becomes narrow, and the horizontal member 2 must be used sideways with the long side wall 2a facing sideways. That is, the reason why the horizontal member 2 is used horizontally is that the upper and lower space S ′ between the horizontal brace 9 and the lower flange 2e of the floor beam 2B is narrow. This is because the span between the floor beam 2B and the floor beam 2C supporting the part is short. In addition, F in FIG. 5 is a ceiling surface. Hereinafter, the case where the hanging wall 1a is attached to the horizontal member 2 used sideways will be described.

  FIG.6 and FIG.7 has shown an example at the time of using the hanging bracket 3 attached to the horizontal member 2 used vertically for the horizontal member 2 used horizontally as it is. The hanging bracket 3 of this example includes a fixing bolt 8 for fixing the bracket main body 3a to the horizontal member 2 in addition to the bracket main body 3a and the suspension bolt 3b. The first bolt hole 4 is used as an insertion hole for the fixing bolt 8, and the second bolt hole 5 provided in the metal fitting back part 3c is used as a fastening hole for the suspension bolt 3b. Other configurations are the same as those of the embodiment of FIGS. 1 to 3, and corresponding portions are denoted by the same reference numerals and detailed description thereof is omitted.

  In this example, when the hanging wall 1a is suspended from the horizontal member 2 to be used horizontally, first, the metal fitting body 3a is externally fitted from below the horizontal member 2, and the horizontal member 2 is held in close contact with the metal fitting. The back portion 3c and the tip of the short side wall 2b of the horizontal member 2 are made to face each other with a gap 7 therebetween. In this state, the first bolt hole 4 of the metal fitting extension 3e protruding upward from the horizontal member 2 is formed. The fixing bolt 8 is inserted from the horizontal direction B and fastened by the nut 12, whereby the upper surface of the horizontal member 2 is pressed and held from above by the fixing bolt 8. Further, the screw 10 is tightened from the screw holes 35 of the holding portions 3d and 3d of the metal fitting body 3a into the screw lower holes of the horizontal member 2, and the upper portion of the suspension bolt 3b is inserted into the second bolt hole 5 of the metal back portion 3c from below. By screwing and fastening, the attachment of the hanging bracket 3 to the horizontal member 2 is completed.

  Therefore, the load G of the hanging wall 1a applied to the suspension bolt 3b is received by the entire horizontal member 2 via the metal fitting body 3a and the fixing bolt 8. Therefore, for example, when the horizontal member 2 is used sideways because the ceiling space S ′ is narrow as shown in FIG. 5, the span between the floor beam 2 </ b> B and the floor beam 2 </ b> C is shortened. The strength of the material 2 can be sufficiently secured, and as a result, the supporting strength of the drooping wall 1a can be increased. Moreover, a method of fastening the suspension bolt 3b to the metal fitting body 3a while holding the horizontal member 2 by the metal fitting body 3a is adopted, and the fixing bolt 8 inserted through the first bolt hole 4 of the metal fitting extension 3e is used. Since the upper surface of the horizontal member 2 is pressed and held from above, positioning of the metal fitting body 3a with respect to the horizontal member 2 in the vertical direction A can be easily performed. Further, the screws 10 can prevent the horizontal direction B and the vertical direction A of the hanging bracket 3 from being displaced with respect to the horizontal member 2. As a result, the attachment of the hanging bracket 3 to the horizontal member 2 can be performed very easily and firmly.

  Further, even if there is a dimensional tolerance between the horizontal member 2 and the metal fitting body 3a, a vertical gap A (adjustment allowance) 7 is provided between the lip 2c of the horizontal material 2 and the metal back portion 3c. Therefore, the gap 7 can sufficiently cope with the dimensional tolerance, and the fixing bolt 8 can maintain the upper and lower gaps 7 in FIG. There is also an advantage that the metal fitting body 3a can be reliably positioned in the vertical direction A.

  Moreover, in this example, since the 1st bolt hole 4 of the metal fitting extension part 3e is used as an insertion hole of the fixing bolt 8, and the 2nd bolt hole 5 is used as a fastening hole of the suspension bolt 3b, the horizontal member 2 used vertically. Can be used as is for the horizontal member 2 for horizontal use, and one type of hanging bracket 3 can be used for both vertical and horizontal use, in terms of cost and work efficiency. Very advantageous.
