TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure for suspending a ceiling panel from a structural body of a building.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, on a ceiling of a building, a ceiling panel such as a gypsum board as a finishing material is hung in a structure as shown in FIG. 13, for example. In the same figure, a suspension lug 110C is joined to a beam (building body) 5 supporting a floor panel (not shown) on the upper floor, and the upper end of the suspension lug 10C is connected to the suspension lug 110C and the lower end is a field support. Each of them is fastened to the edge 20C via 210C, whereby the ceiling panel 6 is suspended.
[0003]
In the conventional ceiling panel suspension structure as described above, the vibration generated by the occupant's operation or the like on the upper floor is easily transmitted through a series of members from the beam 5 to the ceiling panel 4. There is a problem that shaking and noise (particularly, heavy floor impact noise generated by resident jumping) generated on the floor on the upper floor are easily transmitted to the lower floor.
[0004]
Therefore, any one of a series of members from the beam 5 to the ceiling panel 6 is made of an elastic body such as rubber or a spring, or another appropriate member made of an elastic body in the series of members. It has been proposed to interpose a member. This method is intended to reduce the transmission of vibration by making the elastic body absorb vibration from the upper floor.
[0005]
[Problems to be solved by the invention]
However, according to the method described above, although the vibration from the upper floor can be slightly weakened by the elastic body, it is unavoidable that the vibration is transmitted to the lower floor to some extent through the elastic body. The fact is that it is difficult to say that it is sufficiently reduced.
[0006]
The present invention has been made in view of the above-described problems, and provides a suspended structure of a ceiling panel that can sufficiently reduce transmission of vibration from an upper floor to a lower ceiling. The purpose is to:
[0007]
In order to achieve the above object, a suspension structure for a ceiling panel according to the present invention is provided, in which a fishing hook having a C-shaped cross section provided with through holes in an upper horizontal piece and a lower horizontal piece is joined to a skeleton. A fishing tree having a flange formed at an upper end is inserted into a through hole of the upper horizontal piece and the lower horizontal piece, so that the fishing tree is locked to the upper horizontal piece and is movable vertically. An upper horizontal piece having a through hole formed at a lower end of the fishing tree, a hanging piece extending downward from one side edge of the upper horizontal piece, and a lower part extending from a lower edge of the hanging piece. A hanging member having a horizontal piece and a lower vertical piece extending upward from a side edge of the lower horizontal piece is hung by inserting a lower end of a fishing tree through the upper horizontal piece, and In the groove formed by the hanging piece of the bracket, the lower horizontal piece, and the lower vertical piece, Edge received is held, is joined ceiling joists on the lower surface of said wild En受 and is characterized by comprising the ceiling panel attached to said wild edge.
Further, a flange is formed at a lower end portion of the fishing tree, and an upper horizontal piece of the hanging bracket is vertically movably locked to the flange.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a schematic sectional view showing an embodiment of a ceiling panel suspension structure of the present invention. In the figure, a fishing tackle 11 is joined to the lower part of the beam (body) 5, and the upper end of the fishing tackle 1 is locked to the fishing tackle 11. The lower end of the fishing tree 1 is attached to the field margin support 21 via the hanging bracket 12.
[0009]
The fishing catch 11 is a steel member having a C-shaped cross section, and a portion near the edge of the lower horizontal piece 11a is superimposed on the upper surface of the lower flange 5b of the beam 5 made of H-shaped steel, and a bolt is formed. Has been concluded.
[0010]
The lower horizontal piece 11a and the upper horizontal piece 11b of the fishing catch 11 are each provided with a through hole 11c substantially at the center thereof, and the fishing hook 1 is inserted into the through hole 11c.
[0011]
The fishing tree 1 is made of round steel, and a flange 1a is formed at an upper end thereof. The flange 1a is a steel plate, and is joined to the upper end of the fishing tree 1 by welding. When the flange 1a is locked on the upper horizontal piece 11b of the catch 11, the catch 1 is suspended from the catch 11.
[0012]
At this time, the flange 1a is merely mounted on the upper surface of the upper horizontal piece 11b of the fishing catch 11 without being fixed. As a result, the fishing tree 1 can move up and down with respect to the fishing tree receiver 11 (therefore, the fishing tree 1 can move up and down with respect to the beam 5), and the transmission of vibration in this portion is reduced. That is, as shown in FIG. 2, for example, when an impact S in the downward direction is applied to the floor panel 4 on the upper floor, the swing in the downward direction as shown by the arrow in the figure is caused by this. Although transmitted from the beam 4 to the fishing tackle 11 via the beam 5, the fishing tackle 1 is not fixed to the fishing tackle 11, and therefore does not swing directly downward due to the shaking generated in the fishing catch 11. . Therefore, the vibration from the upper floor is hardly transmitted to the fishing tree 1.
[0013]
An elastic body 13 such as a rubber or a spring is interposed between the flange 1a and the upper horizontal piece 11b of the fishing catch 11. As a result, it is possible to reduce the occurrence of vibration and noise due to the upper horizontal piece 11b of the swinging fishing tackle 11 swinging as described above coming into contact with the flange 1a again.
[0014]
As shown in FIG. 1, the hanging fitting 12 includes an upper horizontal piece 12a, a hanging piece 12b extending downward from one side edge of the upper horizontal piece 12a, and a lower horizontal piece 12c extending from a lower end edge of the hanging piece 12b. And a lower vertical piece 12d extending upward from a side edge of the lower horizontal piece 12c.
[0015]
A through hole is provided at a substantially central portion of the upper horizontal piece 12a of the hanging bracket 12, and a lower end of the fishing tree 1 is inserted into the through hole. A male screw portion is formed at the lower end of the fishing tree 1, and an upper horizontal piece 12a of the hanging metal member 12 is held between upper and lower nuts inserted into the male screw portion. It is hung on the lower end of the tree 1. With this configuration, the vertical position of the hanging bracket 12 can be adjusted.
[0016]
In a groove formed by the hanging piece 12b, the lower horizontal piece 12c, and the lower vertical piece 12d of the hanging fitting 12, a field margin receiver 21 is held and inserted into the hanging piece 12b and the lower vertical piece 12d of the hanging fitting 12. The pin 21 is locked in the groove of the hanging fitting 12 by the pin 121. With this configuration, the position of the hanging metal fittings 12 can be adjusted along the length direction of the ridge 21.
[0017]
The ridge 21 is made of a channel steel, and the ridge 2 is joined to the lower surface thereof. Further, a ceiling panel 6 is attached to the edge 2. With the above configuration, the ceiling panel 6 is hung on the beam 5. As described above, the vibration generated on the upper floor is difficult to be transmitted between the fishing tackle 11 and the fishing tackle 1, and therefore is also difficult to be transmitted to the ceiling panel 6. Therefore, transmission of vibration and sound from the upper floor to the lower floor is reduced.
[0018]
In the above embodiment, the fishing tree 1 has a structure that can move up and down with respect to the beam 5, but the fishing tree 1 may have a structure that can move up and down with respect to the ceiling panel 6. May be combined. The same structure as described above can be applied to a portion other than the fishing tree 1 as long as it is between the skeleton and the ceiling panel.
[0019]
FIG. 3 is a schematic sectional view showing another embodiment of the ceiling panel suspension structure of the present invention. In the figure, the configuration and mounting structure of the lower end of the fishing tree 10 are the same as those in the example shown in FIG.
[0020]
At the lower end of the fishing tree 10, a flange 10a is formed. A through hole is provided in the upper horizontal piece 120a of the hanging hardware 120, the fishing tree 10 is inserted into the through hole, and the upper horizontal piece 120a of the hanging hardware 120 is locked to the flange 10a of the fishing tree 10. . The upper horizontal piece 120a of the suspension fitting 120 is placed on the flange 10a of the fishing tree 10 without being fixed. Accordingly, the hanging fitting 120 can move up and down with respect to the fishing tree 10 (therefore, the fishing tree 10 can move up and down with respect to the ceiling panel 6), and transmission of vibration in this portion is reduced. It should be noted that an elastic body 130 is interposed between the upper horizontal piece 120a of the hanging bracket 120 and the flange 10a of the fishing tree 10.
[0021]
FIG. 4 is a cross-sectional view illustrating an example of a floor panel mounting structure. In the same figure, both ends of the locking metal fitting 7 are fitted into the opposing side surfaces of the adjacent floor panel 4 respectively.
[0022]
The locking metal members 7 are for locking the adjacent floor panels 4 so as not to individually swing in the vertical direction. As shown in FIG. 5, the floor panel 4 generally has a plurality of floor panels 4 juxtaposed in the width direction along the beams 5, and both ends of each floor panel 4 are respectively joined to the beams 5. However, conventionally, locking the adjacent floor panels 4 has not been considered. For this reason, since the adjacent floor panels 4 can individually swing in the vertical direction, vibrations are likely to occur due to the movement of a resident on the floor or the like. Here, when the adjacent floor panels 4 are locked to each other as described above, each of the floor panels 4 can be prevented from individually swinging, so that the occurrence of vibration can be reduced.
[0023]
As shown in FIG. 6, the locking fitting 7 is a steel fitting having a projection 71 projecting in both end directions. Each of the protrusions 71 is formed in a conical shape that becomes gradually sharper toward the tip.
[0024]
On the outer peripheral surface of the projection 71, grooves, irregularities, etc. may be provided as appropriate so that the projection 71 is easily fitted into the floor panel 4 and is stably held on the floor panel 4. .
[0025]
The latch 7 can be fitted into the floor panel 4 as shown in FIG. 7, for example. First, as shown in FIG. 7 (a), after the first floor panel 4a is mounted on the beam 5, a side surface along the longitudinal direction of the floor panel 4a (a side surface facing the next floor panel 4b). Then, one protrusion 71a of the locking metal fitting 7 is fitted. In this operation, as shown by the arrow A1 in the figure, the other projection 71b of the locking metal member 7 may be hit with a hammer. For this reason, as shown in FIG. 6, the projecting portions 71a and 71b are formed with a flat surface portion 712 in advance by cutting off the front end portion so as to facilitate the driving operation.
[0026]
A front hole may be provided in advance on the side surface of the floor panel 4a. For example, when the floor panel 4 is made of an ALC (autoclave light weight concrete), a front hole or the like is provided. Even if it is not used, the metal fitting 7 can be easily fitted into the floor panel 4 by hitting with a hammer.
[0027]
The intervals at which the locking fittings 7 are arranged may be determined as appropriate according to the size of the floor panel 4 and the like. For example, in the case of a floor panel 4 of 2000 mm × 500 mm, it is conceivable that the locking members 7 are arranged at intervals of about 500 mm.
[0028]
Next, as shown in FIG. 7 (b), the next floor panel 4b is arranged along the side surface of the floor panel 4a into which the locking metal fitting 7 is fitted, and the exposed protrusion 71b of the locking metal fitting 7 is exposed. Is fitted to one side surface of the next floor panel 4b, and the side surface of the next floor panel 4b is brought into contact with (or close to) the side surface of the first floor panel 4a. At this time, as shown by an arrow A2 in the figure, the floor panel 4b is separated from the other side surface of the next floor panel 4b by appropriate means (for example, hammering with a suitable protective plate interposed therebetween). By hitting the first floor panel 4a, the exposed protrusion 71b of the locking metal member 7 can be fitted into the floor panel 4b.
[0029]
Next, the floor panel 4b is fixed to the beam 5, and thereafter, the same steps as above are repeated to attach a plurality of floor panels 4 to the beam 5.
[0030]
The locking fitting is not limited to the above as long as it can lock an adjacent floor panel. FIG. 8 is a side view showing another example of the locking fitting. The locking metal fitting 70 shown in the figure has a configuration in which conical projections 701 are provided on both surfaces of a plate 703, respectively. In this way, by making the shape of the projection 701 sharper, the locking metal fitting 70 can be more easily fitted into the floor panel. It is also possible to make a change such as projecting a plurality of protrusions 701 on both sides of the plate 703, respectively.
[0031]
The operation of fitting the locking fitting 70 into the floor panel can be easily performed by using the fitting fitting 704 as shown in FIG. The fitting 704 has a configuration in which a flat portion 704b is formed at one end of a cylindrical body 704a, and an inner cavity 704c having a depth greater than the length of one protrusion 701 of the locking fitting 70 is provided. Formed inside. Note that, for example, a plurality of legs may be provided instead of the cylindrical body 704a.
[0032]
When fitting the locking metal fitting 70 to the floor panel, the fitting metal fitting 704 is fitted to the locking metal fitting 70 so as to cover one of the projections 701, and the flat part 704b of the fitting metal fitting 704 is hammered. To hit it. Thereby, the other protrusion 701 can be fitted into the floor panel. Thereafter, the fitting 704 is removed, and the exposed protrusion 701 is fitted into the next floor panel in the same manner as shown in FIG. 7B.
[0033]
FIG. 9 is a partial plan view showing an example of a ceiling panel mounting structure, and FIG. 10 is a cross-sectional view taken along the line xx in FIG. 9 and 10, among the plurality of ceiling panels 6, the ceiling panel 6 adjacent to the length direction (the plurality of ceiling panels 6 in a vertical row) is arranged only in the length direction. It is supported by the rim 20. The edge 20 supports the ceiling panels 6 adjacent to each other in the width direction (the ceiling panels 6 in the next row) individually. Thereby, the ceiling panel 6 adjacent in the length direction is separately supported independently of the ceiling panel 6 adjacent in the width direction.
[0034]
As shown in FIG. 9, the ceiling panels 6 are arranged so that the side edges in the length direction of each ceiling panel 6 are aligned. At this time, each ceiling panel 6 may be brought into contact with another ceiling panel 6 adjacent in the width direction, but as shown in FIG. May be arranged with a slight gap.
[0035]
The bezel 20 is made of a channel steel, and is attached to each of the ceiling panels 6 at a slightly inner side of both longitudinal edges thereof. As shown in FIG. 10, each of the bezels 20 is individually suspended from the beam 5 via a fishing tree 31 and a fishing tree receiver 311.
[0036]
Here, the bezel 20 is separately attached to each of the ceiling panels 6 adjacent in the width direction, and is not arranged in the width direction of the ceiling panel 6. Thus, the ceiling panels 6 adjacent in the length direction (the plurality of ceiling panels 6 forming a vertical row) are separately supported independently of other ceiling panels 6 adjacent in the width direction.
[0037]
Conventionally, as shown in, for example, FIGS. 11 and 12, a plurality of ceiling panels 6 are usually attached to a ridge 200 arranged in the length direction and the width direction, and the ridge 200 is attached to a suspension tree (not shown). ) And suspended on a beam (not shown). In this structure, the adjacent portion of the ceiling panel 6 is supported by one ridge 200, and the ridge 200 is formed in a lattice shape, so that the plurality of ceiling panels 6 are integrally supported. Therefore, since the whole of the plurality of ceiling panels 6 vibrates up and down, low sound is likely to be produced.
[0038]
On the other hand, when some ceiling panels 6 are separately supported independently of other ceiling panels 6 as in the examples shown in FIGS. 9 and 10, the ceiling panels 6 do not vibrate as a whole. Some of them vibrate individually, and therefore, transmission of bass is suppressed. At this time, it is considered that the transmission of the treble increases, but the treble is perceived as noise by intercepting the sound at the floor panel and inserting a sound absorbing material between the floor panel and the ceiling panel 6. The volume can be reduced as a whole.
[0039]
The ridge 20 may be provided only in the width direction of the ceiling panel 6. However, if it is provided only in the length direction of the ceiling panel 6 as described above, the ceiling panel 6 supported by one set of the ridge 2 Since the number of (vertical rows of ceiling panels 6) can be reduced, it is desirable to suppress transmission of bass. Further, some of the ceiling panels 6 in the vertical rows are separated from other ceiling panels 6 by a method such as dividing the bezel 20 into a plurality of pieces in the length direction and individually supporting them. When separately supported in this state, transmission of bass can be more effectively suppressed.
[0040]
The above-described hanging structure of the ceiling panel, the mounting structure of the floor panel, and the mounting structure of the ceiling panel can be applied singly or in combination of two or more of them. The transmission of vibration from the floor to the lower floor can be effectively reduced.
[0041]
【The invention's effect】
As described above, according to the ceiling panel suspension structure of the present invention, a C-shaped fishing tackle having through holes formed in the upper horizontal piece and the lower horizontal piece is joined to the skeleton, and the upper horizontal A fishing tree having a flange formed at an upper end thereof is inserted into a through hole of the piece and the lower horizontal piece, so that the fishing tree is locked to the upper horizontal piece and can be moved up and down to the fishing tree receiver. An upper horizontal piece suspended from the lower end of the fishing tree and provided with a through-hole, a hanging piece extending downward from one edge of the upper horizontal piece, and a lower horizontal piece extending from the lower edge of the hanging piece And a hanging member having a lower vertical piece extending upward from a side edge of the lower horizontal piece is suspended by inserting a lower end of a fishing tree through the upper horizontal piece, and In the groove formed by the hanging piece, the lower horizontal piece, and the lower vertical piece, the field support is held. Which, it is joined ceiling joists on the lower surface of said wild En受. Thus the ceiling panel is attached to wild edge, the upper floor of the floor resulting vibration and noise (by weight floor impact sounds, etc.) to the lower floor It can be difficult to communicate.
