[Technical field]

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

[0002] In buildings, ceiling underlayment materials or various equipment are attached to the beams of the ceiling. Patent Document 1 discloses an attachment structure for ceiling underlayment materials suspended from beams. In the technology of Patent Document 1, an L-shaped steel bar is screwed to a hanging support bracket fixed to the beam.

[0003] [Patent Document 1] JP 2020-183680 A 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 that connect members in the suspension structure. From the viewpoint of preventing loosening of the connections, there is room for improvement in the suspension unit and the building equipped with the suspension unit. [Means for solving the problem]

[0005] (1) A hanging unit that solves the above problem is a hanging unit for suspending an object, comprising: 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, wherein the hanging member has a first connection portion to which the horizontal member is connected, and a support portion provided at a lower position than the first connection portion and supporting the horizontal member from below, wherein the horizontal member has a second connection portion connected to the first connection portion by a first fastening member so that its position can be adjusted in the vertical direction, and the underside of the second connection portion directly contacts the support portion or contacts a first spacer arranged between the second connection portion and the support portion.

[0006] According to this configuration, the horizontal member is adjustable in position relative to the suspending member. When the lower surface 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 portion between the horizontal member and the suspending member due to vibration. When a space is formed between the lower surface of the second connection portion and the support portion by adjusting the height of the horizontal member, a first spacer is disposed between the lower surface of the second connection portion and the support portion. The horizontal member then contacts the first spacer disposed between the second connection portion and the support portion. As a result, the first spacer and the support portion prevent the horizontal member from tilting, thereby preventing loosening of the connection portion between the horizontal member and the suspending 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, it is possible to suppress the positional deviation of the hanging member relative to the ceiling beam due to vibration.

[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 part. With this configuration, the second spacer is disposed between the hanging member and the second reinforcing part. The second spacer allows the second reinforcing part 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 having 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 in which the connection between the hanging member and the horizontal member is unlikely to loosen, and therefore can suitably support an object that is prone to vibration. In addition, the hanging unit has a structure in which the connection between the hanging member and the horizontal member is unlikely to loosen, and therefore the frequency of maintenance of the hanging unit can be reduced.

[0011] (6) In the building of (5) above, the ceiling has a ceiling base, and the ceiling backing material is arranged to intersect with the ceiling backing members constituting the ceiling base, and has a notch through which the ceiling backing member passes in the width direction of the ceiling backing material. With this configuration, the ceiling backing material can intersect with the ceiling backing members. This increases the degree of freedom in arranging the suspension unit. Effect 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 description of the drawings]

[0020] <Hanging unit> As shown in FIG. 4 and FIG. 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. Of the two horizontal members 13, one hanging member 12 is connected to each of both ends in the longitudinal direction of horizontal member 13. First hanging member 12C is connected to one of the ends. Second hanging member 12D is connected to the other end.

[0022] The other horizontal member 13 also has one hanging member 12 connected to each of both longitudinal ends of 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 the 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 contacts the upper surface of the ceiling base material 17. The head of the fixing bolt 17B contacts the ceiling base material 17.

[0025] 6 and 7, the hanging member 12 has a fixing flange portion 12A. The fixing flange portion 12A is a portion that is fixed to the beam hole portion 6A of the ceiling beam 6. The fixing flange portion 12A extends horizontally from an upper end portion 12H of a main body portion 12G of the hanging member 12. The upper end portion 12H includes a curved portion 12J. In addition, a rib plate 12M is provided at the upper end portion 12H of the main body portion 12G so as to bridge a side end 12K of the fixing flange portion 12A and a side end 12L of the 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 fixed portion 12B by fastening the second bolt 16A and the second nut 16B. One of the beam hole portion 6A and the fixed 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 fixed 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 provided at a position lower than first connection portion 12N. Support portion 12P extends horizontally from lower end portion 12Q of main body portion 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 up-down 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 a 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 a first insertion hole 21B.

[0031] In this 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 in a state in which 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 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 a third insertion hole 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 that allows the furring strip 8B (see Fig. 4) to pass through in the width direction of the ceiling base material 17. The size of the cutout portion 17D is formed to allow the furring strip 8B to pass through. The ceiling base material 17 is positioned so as to intersect with the furring strip 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 now be described. The hanging member 12 of the connector 11 included in the hanging unit 10 has a first connection portion 12N to which the horizontal member 13 is connected, and a support portion 12P that supports the horizontal member 13 from below. A second connection portion 13D of the horizontal member 13 is connected to the first connection portion 12N by a first bolt 14A and a first nut 14B so that its position can be adjusted in the vertical direction. A lower surface 13E of the second connection portion 13D directly contacts the support portion 12P.

[0035] In the conventional hanging unit, when vibration is transmitted to the hanging structure, loosening may occur in the connection portion connecting the members. In this regard, according to the present embodiment, as described above, the lower surface 13E of the second connection portion 13D directly contacts the support portion 12P. This prevents the horizontal member 13 from tilting when the fastening state of the first bolt 14A and the first nut 14B deteriorates due to the transmission of vibration. Specifically, the support portion 12P prevents the horizontal member 13 from moving downward in the rotation direction about a line along the insertion direction of the first bolt 14A. This makes it possible to suppress loosening of the connection portion between the hanging member 12 and the horizontal member 13 due to vibration.

[0036] In addition, connector 11 has the following effect. Connector 11 of this embodiment has a structure in which both ends of ceiling backing 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 parts 12P of hanging member 12. Due to this structure, horizontal member 13 is less likely to tilt. Therefore, in this embodiment, even if any one of the four connection parts that are the connection points between hanging member 12 and horizontal member 13 in connector 11 becomes loose, ceiling backing 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. A lower surface 13E of second connection portion 13D directly contacts support portion 12P.

[0038] According to this configuration, the position of horizontal member 13 is adjustable with respect to suspending member 12. Furthermore, lower surface 13E of second connecting portion 13D directly contacts supporting portion 12P. As a result, supporting portion 12P prevents horizontal member 13 from tilting, so loosening of the connection portion between horizontal member 13 and suspending member 12 due to vibration can be suppressed.

[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 in which ceiling beam 6 extends. With this configuration, the position of hanging member 12 can be adjusted in the direction in which ceiling beam 6 extends.

[0040] By adjusting the position of the hanging member 12, the position of the horizontal member 13 to which the ceiling backing material 17 is attached can also be adjusted. This makes it easier to position the ceiling backing material 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) The garage 2 of the building 1 includes a ceiling beam 6 provided on the ceiling 5, a hanging unit 10, and a shutter 4A supported by the hanging unit 10. With this configuration, the shutter 4A can be fixed to the ceiling beam 6 via the hanging unit 10. The hanging unit 10 has a structure in which the connection between the hanging member 12 and the horizontal member 13 is not likely to loosen, and therefore can suitably support the shutter 4A which is prone to vibration. In addition, the hanging unit 10 has a structure in which the connection between the hanging member 12 and the horizontal member 13 is not likely to loosen, and therefore the frequency of maintenance of the hanging unit 10 can be reduced.

[0042] (5) The ceiling backing material 17 is arranged to intersect with the rafters 8B. The ceiling backing member 8 has a notch 17D in the width direction of the ceiling backing material 17 through which the rafters 8B pass. This configuration allows the ceiling backing material 17 to intersect with the rafters 8B. This increases the freedom of arrangement of 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 the first embodiment will be denoted by the same reference numerals as those in the first embodiment. Descriptions of overlapping components will be omitted.

[0044] The present embodiment will be described with reference to Figures 9 and 10. The present 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 FIG. 9 and FIG. 10, a first spacer 15 is disposed between the second connection portion 13D of the horizontal member 13 and the support portion 12P of the hanging member 12. The lower surface 13E of the second connection portion 13D contacts the first spacer 15. The first spacer 15 has a fifth insertion hole 15A through which the third bolt 18A is inserted. The first spacer 15 is configured to fill a space formed by adjusting the height of the horizontal member 13. If the space generated between the second connection portion 13D of the horizontal member 13 and the support portion 12P cannot be filled by one first spacer 15, the space can be filled by stacking a plurality of first spacers 15. There is one first spacer 15 in this embodiment.

[0046] According to the configuration of this embodiment, horizontal member 13 is prevented from tilting by first spacer 15. This makes it possible to suppress 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 the first embodiment will be denoted by the same reference numerals as those in the first embodiment. Descriptions of overlapping components will be omitted.

[0048] The present embodiment will be described with reference to Fig. 11. The present embodiment differs from the first embodiment in that the hanging unit 10 includes a reinforcing bracket 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 metal fitting 19. The reinforcing metal fitting 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 cross 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 metal fitting 19 is attached to the hanging member 12 fixed to the ceiling beam 6 such 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 fitting 19 is attached will be referred to as the "metal fitting attached state."

[0050] Moreover, 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. When the space generated between the hanging member 12 and the second reinforcing portion 19B cannot be filled by one second spacer 23, the space can be filled by stacking a plurality of second spacers 23. There are two second spacers 23 in this embodiment.

[0051] The ceiling beam 6 has a beam hole portion 6A. The beam hole portion 6A is a portion including a hole. The sixth insertion hole 19E of the first reinforcing portion 19A is configured so that the sixth insertion hole 19E overlaps with the beam hole portion 6A when the reinforcing metal fitting 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. The first reinforcing fastening member 19G in this embodiment is a bolt and a nut.

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

[0053] The configuration of this embodiment provides the following two advantages. (1) The reinforcing metal fittings 19 can reinforce the fixation between the ceiling beam 6 and the hanging member 12. This can prevent the position of the hanging member 12 from shifting relative to the ceiling beam 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 forms that the hanging unit 10 and the building 1 can take, and are not intended to limit the forms. The hanging unit 10 and the building 1 can take forms different from those exemplified in the above-described embodiments. One example is a form in which part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. An example of a modified embodiment is 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-fastening base 4M. Both ends of the handle 4K are supported by the support rod 4L. The support rod 4L is connected to the screw-fastening base 4M. The support rod 4L is attached to the ceiling backing material 17 via the screw-fastening base 4M and the ceiling material 7B by a screw driven into the screw-fastening base 4M.

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