Description

[Technical Field]

[0001] The present disclosure relates to a hanging unit and a building. [Background technology]

[0002] In buildings, ceiling underlayment materials or various types of equipment are attached to ceiling beams. Patent Document 1 discloses an attachment structure for ceiling underlayment materials that are suspended from beams. In the technology of Patent Document 1, an L-shaped steel rod is fastened with screws to a hanging support bracket that is fixed to the beam. A plurality of screw insertion holes are provided in the connection portion of the hanging support bracket where the L-shaped steel rod is connected (referred to as the screw fastening portion in Patent Document 1).

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-183680 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when vibrations are transmitted to a building, loosening may occur in the connections connecting members in the suspension structure. From the viewpoint of preventing loosening of the connections, there is room for improvement in suspension units and buildings equipped with suspension units. [Means for solving the problem]

[0005] (1) A suspension unit that solves the above problem is a suspension unit for suspending an object, and comprises a connector fixed to a ceiling beam and a ceiling backing material attached to the connector and supporting the object, wherein the connector has a hanging member fixed to the ceiling beam and a horizontal member connected to the hanging member, the hanging member having a first connection part to which the horizontal member is connected and a support part that is located lower than the first connection part and supports the horizontal member from below, the horizontal member having a second connection part that is connected to the first connection part by a first fastening member so that its position can be adjusted in the vertical direction, and the underside of the second connection part directly contacts the support part or contacts a first spacer that is arranged between the second connection part and the support part.

[0006] According to this configuration, the horizontal member is adjustable in position relative to the hanging member. When the underside of the second connection portion directly contacts the support portion, the support portion prevents the horizontal member from tilting, thereby preventing loosening of the connection between the horizontal member and the hanging member due to vibration. When a space is formed between the underside of the second connection portion and the support portion due to height adjustment of the horizontal member, a first spacer is disposed between the underside of the second connection portion and the support portion. The second connection portion then contacts the first spacer disposed between the second connection portion and the support portion. Therefore, the first spacer and the support portion prevent the horizontal member from tilting, thereby preventing loosening of the connection between the horizontal member and the hanging member due to vibration.

[0007] (2) In the hanging unit of (1) above, the ceiling beam has a beam hole portion, the hanging member has a fixing flange portion fixed to the beam hole portion of the ceiling beam, and the fixing flange portion has a fixing portion fixed to the beam hole portion by a second fastening member so as to be position-adjustable in the longitudinal direction in which the ceiling beam extends. With this configuration, the position of the hanging member can be adjusted in the direction in which the ceiling beam extends.

[0008] (3) The hanging unit of (1) above further includes a reinforcing metal fitting, the reinforcing metal fitting having a first reinforcing portion configured to abut against the ceiling beam and a second reinforcing portion configured to face the hanging member, the first reinforcing portion having a first connecting portion that connects to the ceiling beam, and the second reinforcing portion having a second connecting portion that connects to the hanging member. With this configuration, the reinforcing metal fitting can reinforce the fixation between the ceiling beam and the hanging member. Therefore, displacement of the hanging member relative to the ceiling beam due to vibration can be suppressed.

[0009] (4) The hanging unit of (3) above further includes a second spacer, the second spacer being disposed between the hanging member and the second reinforcing portion. With this configuration, the second spacer is disposed between the hanging member and the second reinforcing portion. The second spacer allows the second reinforcing portion to be disposed in a position that is easy to attach. This makes it easy to install the hanging unit.

[0010] (5) A building that solves the above problem is a building with a ceiling, comprising: a ceiling beam provided on the ceiling; a hanging unit according to any one of (1) to (4) above; and an object supported by the hanging unit. With this configuration, the object can be fixed to the ceiling beam via the hanging unit. The hanging unit has a structure that makes it difficult for the connection between the hanging member and the horizontal member to loosen, so it can suitably support an object that is prone to vibration. Furthermore, the hanging unit has a structure that makes it difficult for the connection between the hanging member and the horizontal member to loosen, so the frequency of maintenance of the hanging unit can be reduced.

[0011] (6) In the building described in (5) above, the ceiling has a ceiling substrate, and the ceiling substructure material is arranged so as to intersect with the ceiling substrate members that constitute the ceiling substrate, and has a notch in the width direction of the ceiling substructure material through which the ceiling substrate members pass. With this configuration, the ceiling substructure material can intersect with the ceiling substrate members. This increases the degree of freedom in arranging the suspension unit. [Effects of the Invention]

[0012] According to the hanging unit of the present disclosure, loosening of the connection part of the connector due to vibration can be suppressed. According to the building of the present disclosure, loosening of the connection part of the connector due to vibration can be suppressed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0014] First Embodiment The building 1 and the suspension unit 10 will be described with reference to Figures 1 to 8. Hereinafter, the building 1 includes at least one suspension unit 10. In the first embodiment, the building 1 includes four suspension units 10.

[0015] As shown in FIG. 1, the building 1 in this embodiment is a detached house. Examples of the building 1 that differ from the first embodiment include an apartment building and a public facility. The building 1 in this embodiment is composed of a building main body 3 and a garage 2. The garage 2 has an opening wall 2A with an opening. A shutter 4A is provided at the opening of the opening wall 2A to close the opening. As an example, the garage 2 has an interior space large enough to accommodate a car 9.

[0016] As shown in Figures 2 and 3, the garage 2 of the building 1 includes ceiling beams 6 (see Figure 4) installed on the ceiling 5, suspension units 10, and an object 4 supported by the suspension units 10. In this embodiment, the ceiling beams 6 are H-shaped steel. Note that the ceiling beams 6 are not shown in Figures 2 and 3. In this embodiment, the object 4 is an overslider-type shutter 4A. The shutter 4A is supported by four suspension units 10. Examples of the object 4 that differ from this embodiment include fitness equipment 4J (described below), a hammock, a projection screen, a large television, etc. The number of suspension units 10 varies depending on the size and weight of the object 4.

[0017] The shutter 4A includes a rail 4B and multiple slats 4C. The rail 4B is composed of a vertical section 4D that follows the vertical direction of the opening wall 2A, a horizontal section 4E that follows the ceiling 5, and a curved rail section 4F that connects the vertical section 4D and the horizontal section 4E. The multiple slats 4C are connected to each other in the width direction of the slats 4C. When the shutter 4A is opened, the multiple slats 4C slide along the rail 4B and are accommodated so as to follow the ceiling 5.

[0018] As shown in Figures 3 and 4, the ceiling 5 has a ceiling substrate 7A and a ceiling material 7B. The ceiling substrate 7A is composed of a ceiling substrate member 8. The ceiling substrate member 8 includes a joist support 8A and a joist 8B. In a plan view of the ceiling 5, the joist support 8A intersects with the joist 8B.

[0019] As shown in Fig. 4, the shutter 4A is suspended from the suspension unit 10 via the ceiling 5 and a rail mounting bracket 4G. Specifically, the horizontal portion 4E of the rail 4B is attached to the rail mounting bracket 4G. The rail mounting bracket 4G is attached to the ceiling backing material 17 via a ceiling material 7B by mounting members 4H. In this embodiment, the mounting members 4H are screws.

[0020] <Hanging unit> As shown in Figures 4 and 5, the suspension unit 10 that suspends the shutter 4A includes a connector 11 fixed to the ceiling beam 6 and a ceiling backing material 17 that supports the shutter 4A. The connector 11 includes a hanging member 12 fixed to the ceiling beam 6 and a horizontal member 13 connected to the hanging member 12. In this embodiment, the horizontal member 13 is a lip channel steel. The horizontal member 13 has an opening 13A. For each face along the longitudinal direction of the horizontal member 13, the face that forms the opening 13A intersects with two side faces 13B. The face that has the opening 13A is connected to the back face 13C via the two side faces 13B.

[0021] Hanging member 12 has first connection portion 12N to which horizontal member 13 is connected (see FIG. 7). In this embodiment, connector 11 is composed of four hanging members 12 and two horizontal members 13. One of the two horizontal members 13 has one hanging member 12 connected to each of both longitudinal ends of horizontal member 13. First hanging member 12C is connected to one of the two ends. Second hanging member 12D is connected to the other end.

[0022] Similarly, hanging members 12 are connected to both longitudinal ends of the other horizontal member 13. Third hanging member 12E is connected to one of the ends, and fourth hanging member 12F is connected to the other.

[0023] In this embodiment, back surface 13C of one of two horizontal members 13 faces back surface 13C of the other horizontal member 13. First hanging member 12C, second hanging member 12D, third hanging member 12E, and fourth hanging member 12F each contact back surface 13C of the horizontal member 13 to which they are connected.

[0024] In this embodiment, the ceiling base material 17 is a square pipe. The ceiling base material 17 is attached to the horizontal member 13 of the connector 11 by a fixing member 17A. In this embodiment, the fixing member 17A is a fixing bolt 17B and a fixing nut 17C. The fixing bolt 17B penetrates the ceiling base material 17 and one of the two side surfaces 13B of the horizontal member 13 that is in contact with the top surface of the ceiling base material 17. The head of the fixing bolt 17B contacts the ceiling base material 17.

[0025] As shown in FIGS. 6 and 7, hanging member 12 has fixing flange portion 12A. Fixing flange portion 12A is a portion that is fixed to beam hole portion 6A of ceiling beam 6. Fixing flange portion 12A extends horizontally from upper end portion 12H of main body portion 12G of hanging member 12. Upper end portion 12H includes curved portion 12J. In addition, rib plate 12M is provided at upper end portion 12H of main body portion 12G to bridge side end 12K of fixing flange portion 12A and side end 12L of main body portion 12G.

[0026] The ceiling beam 6 has a beam hole portion 6A. Specifically, the ceiling beam 6, which is an H-shaped steel in this embodiment, has the beam hole portion 6A in a flange extending from the lower end of the web. The beam hole portion 6A is a portion that includes a hole. The fixing flange portion 12A has a fixing portion 12B. The fixing portion 12B is fixed to the beam hole portion 6A by a second fastening member 16 so that its position can be adjusted in the longitudinal direction in which the ceiling beam 6 extends.

[0027] In this embodiment, the second fastening member 16 is a second bolt 16A and a second nut 16B. The beam hole portion 6A is connected to the fixing portion 12B by fastening the second bolt 16A and the second nut 16B. One of the beam hole portion 6A and the fixing portion 12B has a second elongated hole 20A that adjusts the position of the hanging member 12 relative to the ceiling beam 6 in the longitudinal direction of the ceiling beam 6. The other of the beam hole portion 6A and the fixing portion 12B has a second insertion hole 20B.

[0028] In this embodiment, fixing portion 12B has second elongated hole 20A. Second bolt 16A is inserted through second elongated hole 20A and second insertion hole 20B from the underside of fixing flange portion 12A. Second elongated hole 20A is configured so that the position of hanging member 12 can be adjusted along the longitudinal direction of ceiling beam 6 when second bolt 16A is inserted through second elongated hole 20A and second insertion hole 20B.

[0029] Hanging member 12 has support portion 12P, which is located at a lower position than first connection portion 12N. Support portion 12P extends horizontally from lower end portion 12Q of main body 12G of hanging member 12. Support portion 12P is configured to support horizontal member 13 from below. Horizontal member 13 has second connection portion 13D. Second connection portion 13D is connected to first connection portion 12N of hanging member 12 by first fastening member 14 so that its position can be adjusted in the vertical direction. A lower surface 13E (see FIG. 5) of second connection portion 13D of horizontal member 13 directly contacts support portion 12P.

[0030] In this embodiment, first fastening member 14 is a first bolt 14A and a first nut 14B. First connection portion 12N of hanging member 12 is connected to second connection portion 13D of horizontal member 13 by fastening first bolt 14A and first nut 14B. One of first connection portion 12N and second connection portion 13D has first elongated hole 21A that adjusts the height position of horizontal member 13 relative to hanging member 12. The other of first connection portion 12N and second connection portion 13D has first insertion hole 21B.

[0031] In the present embodiment, first connection portion 12N of hanging member 12 has first elongated hole 21A. First bolt 14A is inserted through first elongated hole 21A and first insertion hole 21B from the hanging member 12 side. First elongated hole 21A is configured so that the height position of horizontal member 13 relative to hanging member 12 can be adjusted when first bolt 14A is inserted through first elongated hole 21A and first insertion hole 21B.

[0032] Additionally, the support portion 12P and the horizontal member 13 are fastened together by a third fastening member 18. In this embodiment, the third fastening member 18 is a third bolt 18A and a third nut 18B. The horizontal member 13 has third insertion holes 22A, through which the third bolt 18A is inserted, on two side surfaces 13B of the second connection portion 13D. The support portion 12P has a fourth insertion hole 22B, through which the third bolt 18A is inserted.

[0033] As shown in FIG. 8, the ceiling base material 17 has a cutout portion 17D in the width direction of the ceiling base material 17, through which the rafters 8B (see FIG. 4) pass. The size of the cutout portion 17D is formed to allow the rafters 8B to pass through. The ceiling base material 17 is arranged so as to intersect with the rafters 8B (see FIG. 3). The ceiling base material 17 may have multiple cutout portions 17D.

[0034] <Actions and Effects of the Embodiment> The operation of this embodiment will be described. Hanging member 12 of connector 11 included in hanging unit 10 has first connection portion 12N to which horizontal member 13 is connected, and support portion 12P that supports horizontal member 13 from below. Second connection portion 13D of horizontal member 13 is connected to first connection portion 12N by first bolt 14A and first nut 14B so that its position can be adjusted in the vertical direction. Lower surface 13E of second connection portion 13D directly contacts support portion 12P.

[0035] In conventional suspension units, the transmission of vibrations to the suspension structure can cause loosening of the connection between members. In this regard, according to the present embodiment, as described above, lower surface 13E of second connection portion 13D directly contacts support portion 12P. This prevents horizontal member 13 from tilting if the fastening state of first bolt 14A and first nut 14B deteriorates due to the transmission of vibrations. Specifically, support portion 12P prevents horizontal member 13 from moving downward in the rotational direction about a line along the insertion direction of first bolt 14A. This prevents loosening of the connection between hanging member 12 and horizontal member 13 due to vibrations.

[0036] Furthermore, connector 11 has the following effect. Connector 11 of the present embodiment has a structure in which both ends of ceiling subfloor material 17 are supported by hanging structures. Each of the two hanging structures includes horizontal member 13 and hanging members 12 connected to both ends of horizontal member 13. Each end of horizontal member 13 is supported from below by support portions 12P of hanging member 12. This structure makes horizontal member 13 less likely to tilt. Therefore, in the present embodiment, even if one of the four connection portions between hanging member 12 and horizontal member 13 in connector 11 becomes loose, ceiling subfloor material 17 is less likely to tilt.

[0037] The effects of this embodiment will be described. (1) Hanging member 12 has first connection portion 12N to which horizontal member 13 is connected, and support portion 12P that supports horizontal member 13 from below. Horizontal member 13 has second connection portion 13D that is connected to first connection portion 12N by first bolt 14A and first nut 14B so that its position can be adjusted in the vertical direction. Lower surface 13E of second connection portion 13D directly contacts support portion 12P.

[0038] With this configuration, the position of horizontal member 13 can be adjusted relative to hanging member 12. Furthermore, lower surface 13E of second connecting portion 13D directly contacts support portion 12P. As a result, support portion 12P prevents horizontal member 13 from tilting, thereby preventing loosening of the connection portion between horizontal member 13 and hanging member 12 due to vibration.

[0039] (2) Fixing flange portion 12A has fixing portion 12B that is fixed to beam hole portion 6A so as to be position adjustable in the longitudinal direction of extension of ceiling beam 6. With this configuration, the position of hanging member 12 can be adjusted in the direction of extension of ceiling beam 6.

[0040] By adjusting the position of the hanging member 12, the position of the horizontal member 13 to which the ceiling substrate 17 is attached can also be adjusted. This makes it easier to position the ceiling substrate 17 in a position close to the center of gravity of the object 4 supported by the hanging unit 10. This makes it easier for the hanging unit 10 to support the object 4.

[0041] (4) Garage 2 of building 1 includes ceiling beams 6 attached to ceiling 5, hanging unit 10, and shutter 4A supported by hanging unit 10. With this configuration, shutter 4A can be fixed to ceiling beam 6 via hanging unit 10. Hanging unit 10 has a structure that makes it difficult for the connection between hanging member 12 and horizontal member 13 to loosen, and therefore can suitably support shutter 4A, which is prone to vibration. Furthermore, hanging unit 10 has a structure that makes it difficult for the connection between hanging member 12 and horizontal member 13 to loosen, and therefore can reduce the frequency of maintenance of hanging unit 10.

[0042] (5) The ceiling subfloor material 17 is positioned so as to intersect with the rafters 8B. The ceiling subfloor member 8 has a notch 17D in the width direction of the ceiling subfloor material 17, through which the rafters 8B pass. This configuration allows the ceiling subfloor material 17 to intersect with the rafters 8B. This increases the degree of freedom in arranging the hanging unit 10.

[0043] Second Embodiment A suspension unit 10 according to a second embodiment will be described. In this embodiment, components common to those in the first embodiment will be assigned the same reference numerals as those in the first embodiment. Descriptions of overlapping components will be omitted.

[0044] This embodiment will be described with reference to Figures 9 and 10. This embodiment differs from the first embodiment in that a first spacer 15 is disposed between the horizontal member 13 and the support portion 12P.

[0045] As shown in FIGS. 9 and 10 , a first spacer 15 is disposed between second connection portion 13D of horizontal member 13 and support portion 12P of hanging member 12. A lower surface 13E of second connection portion 13D contacts first spacer 15. First spacer 15 has fifth insertion hole 15A through which third bolt 18A is inserted. First spacer 15 is configured to fill a space formed by adjusting the height of horizontal member 13. If a single first spacer 15 cannot fill the space between second connection portion 13D of horizontal member 13 and support portion 12P, the space can be filled by stacking multiple first spacers 15. In this embodiment, there is only one first spacer 15.

[0046] According to the configuration of this embodiment, first spacer 15 prevents horizontal member 13 from tilting, which makes it possible to prevent loosening of the connection between horizontal member 13 and hanging member 12 due to vibration.

[0047] Third Embodiment A suspension unit 10 according to a third embodiment will be described. In this embodiment, components common to those in the first embodiment will be assigned the same reference numerals as those in the first embodiment. Descriptions of overlapping components will be omitted.

[0048] This embodiment will be described with reference to Fig. 11. This embodiment differs from the first embodiment in that the hanging unit 10 includes a reinforcing metal fitting 19 that reinforces the portion where the hanging member 12 is fixed to the ceiling beam 6.

[0049] As shown in FIG. 11 , the hanging unit 10 further includes a reinforcing bracket 19. The reinforcing bracket 19 has a first reinforcing portion 19A configured to abut against the ceiling beam 6 and a second reinforcing portion 19B configured to face the hanging member 12. The first reinforcing portion 19A is connected to the second reinforcing portion 19B so as to intersect with each other. The first reinforcing portion 19A has a first connecting portion 19C that connects to the ceiling beam 6. The first connecting portion 19C has a sixth insertion hole 19E. The second reinforcing portion 19B has a second connecting portion 19D that connects to the hanging member 12. The second connecting portion 19D has a seventh insertion hole 19F. The reinforcing bracket 19 is attached to the hanging member 12, which is fixed to the ceiling beam 6, so that the first reinforcing portion 19A abuts against the ceiling beam 6 and the second reinforcing portion 19B faces the hanging member 12. Hereinafter, this state in which the reinforcing metal fittings 19 are attached will be referred to as the "metal fitting attached state."

[0050] The hanging unit 10 further includes a second spacer 23. The second spacer 23 is disposed between the hanging member 12 and the second reinforcing portion 19B. The second spacer 23 is configured to fill the space between the hanging member 12 and the second reinforcing portion 19B. If the space between the hanging member 12 and the second reinforcing portion 19B cannot be filled with one second spacer 23, the space can be filled by stacking a plurality of second spacers 23. In this embodiment, there are two second spacers 23.

[0051] The ceiling beam 6 has a beam hole portion 6A. The beam hole portion 6A is a portion that includes a hole. The sixth insertion hole 19E of the first reinforcing portion 19A is configured so that the sixth insertion hole 19E overlaps the beam hole portion 6A when the reinforcing bracket 19 is in a metal fitting installation state. The first reinforcing fastening member 19G passes through the sixth insertion hole 19E and the hole of the beam hole portion 6A. The first reinforcing fastening member 19G fastens the ceiling beam 6 and the first reinforcing portion 19A together. In this embodiment, the first reinforcing fastening member 19G is a bolt and a nut.

[0052] The hanging member 12 has a downward insertion hole 12R at a position overlapping with the seventh insertion hole 19F of the second reinforcing portion 19B facing the hanging member 12. The second spacer 23 has an eighth insertion hole 23A at a position overlapping with the seventh insertion hole 19F of the second reinforcing portion 19B. The second reinforcing fastening member 19H passes through the seventh insertion hole 19F, the hanging insertion hole 12R, and the eighth insertion hole 23A. The second reinforcing fastening member 19H fastens the hanging member 12, the second reinforcing portion 19B, and the second spacer 23 together. In this embodiment, the second reinforcing fastening member 19H is a bolt and a nut.

[0053] The configuration of this embodiment provides the following two effects. (1) Reinforcement metal fittings 19 can reinforce the fixation between ceiling beams 6 and hanging members 12. This can prevent the position of hanging members 12 from shifting relative to ceiling beams 6 due to vibration.

[0054] (2) Second spacer 23 is disposed between hanging member 12 and second reinforcing portion 19B. Second spacer 23 allows second reinforcing portion 19B to be disposed in a position that is easy to attach. This makes it easy to install hanging unit 10.

[0055] <Modification> The above-described embodiments are examples of possible forms of the hanging unit 10 and the building 1, and are not intended to limit the forms. The hanging unit 10 and the building 1 may take forms different from those illustrated in the above-described embodiments. Examples of such forms include forms in which part of the configuration of the embodiments is replaced, modified, or omitted, or forms in which a new configuration is added to the embodiments. Examples of modified embodiments are shown below.

[0056] (1) As shown in FIG. 12, the object 4 may be a fitness tool 4J. The fitness tool 4J is supported by two hanging units 10. The fitness tool 4J is composed of a handle 4K, a support rod 4L, and a screw-mounted base 4M. Each end of the handle 4K is supported by the support rod 4L. The support rod 4L is connected to the screw-mounted base 4M. The support rod 4L is attached to the ceiling base material 17 via the screw-mounted base 4M and the ceiling material 7B by a screw driven into the screw-mounted base 4M.

[0057] (2) Hanging unit 10 may be connected to horizontal members 13 by hanging members 12 so as to cantilever horizontal members 13. For example, of the two horizontal members 13 in the first embodiment, only first hanging member 12C is directly connected to back surface 13C of one horizontal member 13. Only third hanging member 12E is directly connected to back surface 13C of the other horizontal member 13. [Explanation of symbols]
