Description

Description: TECHNICAL FIELD The present invention relates to a ceiling support structure in a connecting portion of upper floor panels.

[Background technology]

Conventionally, as shown in FIG.
The metal receiving objects 53 and 54 were welded to 1 or the floor beam 52, and were mounted and fixed to this. In addition, 57 is a floor panel on the second floor that is provided by straddling the barrel 51 and the floor beam 52,
Further, reference numeral 56 is a ceiling panel hung by a hanging tree 55 on a ceiling hanging tree receiver 50. FIG. 6 shows the support structure of the ceiling at the location where the floor panels 58 and 59 are connected by the floor panel joint hardware 60. There is no horizontal bridge member such as a girder or floor beam at the connecting portion of the floor panels 58 and 59, and therefore, there is no receiving object for supporting the ceiling hanging bridge. Therefore, it is not possible to provide the ceiling hanging bridge in the direction in which the floor panels 58 and 59 are arranged (the direction parallel to the paper surface), and as shown in the figure, the direction along the connecting portion of the floor panels 58 and 59 ( The ceiling hanging tree bridge 61 could be provided only in the direction (perpendicular to the paper surface).

The ceiling panel 56 includes a hanging tree 55, a ceiling hanging tree bridge 50,
It is connected to the floor panel 57 via the receivables 53 and 54, and there is a problem that vibration and sound of the floor panel 57 are transmitted to the ceiling panel 56, or conversely, they are transmitted from the ceiling panel 56 to the floor panel 57.

[Object of the Invention]

An object of the present invention is to provide a ceiling support structure in which the ceiling hanging bridge can be easily fixed even in a place where a receiving object for receiving the ceiling hanging bridge is not attached, and which is excellent in vibration and soundproofing. It is to be.

[Disclosure of Invention]

The ceiling support structure according to the present invention includes a ceiling hanging tree beam, which extends along the connecting portion of a floor panel on an upper floor and has both ends fixed to a horizontal member, and the ceiling hanging tree beam. The ceiling hanging tree support supporting member fixed above, the ceiling hanging tree receiving member mounted on the ceiling hanging tree receiving supporting member and extending in the direction perpendicular to the longitudinal direction of the ceiling hanging tree receiving beam, and the ceiling hanging tree receiving member. And a ceiling base panel hung by the ceiling hanging hardware.

According to the configuration of the present invention, there are the following effects. In other words, the ceiling hanging tree bridge can be supported by the ceiling hanging tree bridge, and the ceiling hanging tree bridge can be fixed even in a place where the metal receiving object cannot be attached.

In addition, the ceiling base panel is hung by the ceiling hanging bridge supported by the ceiling hanging bridge. Therefore, the ceiling base panel and the floor panels on the upper floor are separated from each other, and vibrations and sounds of each other are not transmitted to the other, so that it is possible to provide a ceiling support structure excellent in vibration and soundproofing.

An embodiment of the present invention will be described with reference to FIGS. In the figure, 1 and 2 are floor panels on the adjacent second floor. The floor panels 1 and 2 are formed by panel frames 3 and 4 having an outwardly-grooved periphery, and have honeycomb cores 5 and 6 inside.
Is installed. Further, inwardly grooved metal fittings 7, 8 are fitted and fixed to the panel frames 3, 4. 9
Is an upward groove-shaped floor panel joint hardware for connecting the floor panels 1 and 2. The floor panels 1 and 2 are connected to each other by fixing the respective joining hardware 7 and 8 to the flange pieces 9a and 9b of the floor panel joint hardware 9 with fasteners (not shown). Reference numeral 15 denotes a ceiling hanging tree beam of a lip channel steel provided below the floor panels 1 and 2. The ceiling hanging tree receiving beam 15 is provided so as to extend in parallel with the floor panel joint metal fitting 9, and the end portion extends in the direction in which the floor panels 1 and 2 are arranged (the direction parallel to the paper surface) via an end plate or the like. It is fixed to a horizontal member (not shown) such as an insert. This ceiling hanging tree receiving beam 1
On the upper surface of the lip piece 15a of No. 5, the ceiling hanging tree receiving support hardware 16 extending in the direction perpendicular to the ceiling hanging tree receiving beam 15 and upwardly grooved steel is provided.
Is fixed. The ceiling hanging tree bridges 17 and 18 are made of lip grooved steel, and end plates 1 are attached to the ends.
9 and 20 are welded. These ceiling hanging bridges 17,1
8 is mounted by fitting the respective ends to the ceiling hanging tree support metal 16 in a posture in which the opening is laterally oriented. The ceiling undercarriage panel 17 is hung by hooking the ceiling hanging hardware 21 as shown in FIG. 3 and FIG. 4 on the ceiling hanging tree bridges 17 and 18 thus supported. That is, the ceiling hanging hardware 21 is formed by twisting a rectangular metal piece 90 degrees in the middle and folding back the upper end. The ceiling hanging hardware 21 is hooked on the ceiling hanging tree bridge 18, and the lower part thereof is used as the field bridge 2 of the ceiling base panel 10.
2 is fixed with a galvanized iron round nail 23. The ceiling base panel 10 is hung by arranging such ceiling hanging hardware 21 at a plurality of locations. The ceiling base panel 10 is composed of a field edge 22, a field edge 11 and a ceiling discarding board 12 attached to the lower surface of the field edge 11 and the like. Further, a ceiling mesh plate 13 is provided on the upper surface of the ceiling base panel 10 in contact with the lower surface of the ceiling hanging tree beam 15. Further, field edge runners 14 are provided side by side on both sides of the ceiling panel 13.

According to the ceiling support structure configured as described above, the ceiling hanging tree receiving beam 15 can suspend the ceiling hanging tree receiving members 17 and 18 via the ceiling hanging tree receiving supporting hardware 16. Therefore,
Floor panel joints Ceiling hanging wooden bridges 17 and 18 like hardware 9
It is possible to easily fix the ceiling hanging tree bridges 17 and 18 even in a place where a receiving object for receiving the ceiling can not be attached.

Further, the ceiling base panel 10 includes a ceiling hanging tree receiving beam 15 and a ceiling hanging tree receiving member 17, which are supported by a ceiling hanging tree receiving supporting metal member 16,
Suspended at 18. Therefore, the ceiling base panel 10
And the floor panels 1 and 2 are separated from each other,
The vibrations and sounds of the floor panels 1 and 2 on the second floor are transmitted to the ceiling base panel 10 on the first floor, or vice versa.
Can be prevented from being transmitted to the floor panels 1 and 2, and a ceiling support structure excellent in vibration proofing and soundproofing can be provided.

Further, it becomes possible to provide the ceiling hanging tree bridges 17 and 18 at the portion of the floor panel joint metal fitting 9 so as to extend in the direction in which both floor panels 1 and 2 are arranged, and as shown in FIG. When used together with the method of providing the ceiling hanging tree bridge extending along the connecting portion of, the ceiling hanging tree bridge can be made orthogonal to each other. Therefore, it is possible to easily reinforce when mounting a heavy lighting device.

〔The invention's effect〕

According to the present invention, a ceiling support structure can be provided in which the ceiling hanging bridge can be easily fixed even at a place where a receiving object for receiving the ceiling hanging bridge is not attached, and which is excellent in vibration and sound insulation. The effect is that you can do it.
