[Technical field]
[0001] This invention relates to a ceiling structure, and more particularly to a ceiling structure and a roof structure equipped with the same that do not require the installation of sound absorbing materials, heat insulating materials, or sound insulating materials in the attic from the inside of the room. [Background technology]
[0002] Conventionally, insulation materials have been installed in the attic in order to improve the thermal insulation performance of the interior of the building. Conventionally, this construction has been carried out by setting up scaffolding from inside the building. This has resulted in a long construction period and an increase in construction costs.
[0003] In order to solve the problems of the conventional technology, Patent Document 1 makes the following proposal with the aim of providing a construction method for a roof, including a ceiling, that does not require construction from the ceiling side of a building, can be constructed easily and in a short period of time, and has sufficient roof characteristics and sufficient ceiling characteristics.
[0004] That is, as shown in Figure 9, a construction method for a roof 100 including a ceiling is proposed, which comprises a first step in which a ceiling support frame 102 protruding upward at a predetermined interval is fixed to the upper surface of a body 101 extending in the left-right direction; a second step in which a plurality of ceiling materials 103 having upright connection parts on the left and right are connected on the ceiling support frame 102; a third step in which insulation material 105 is laid on the ceiling material 103 and a receiving part formed at the upper end of a retaining clip 104 is exposed from the surface of the insulation material 105; and a fourth step in which roof material 106 is attached from the left and right of the receiving part, characterized in that all of these first to fourth steps are performed from above.
[0005] However, in the roof 100 including the ceiling proposed in Patent Document 1, a ceiling material 103 is provided on the surface facing the room, and as a result, there is a problem that the sound generated in the room is reflected by the ceiling material 103 and causes reverberation in the room. In other words, there is a problem of the generation of ringing noise. In addition, there is also a problem of increased costs due to the provision of the ceiling material 103.
[0006] Moreover, the ceiling material 103 is generally made of steel plate, which increases the weight of the ceiling, and therefore the strength of the structure must be able to withstand the increased weight, resulting in an increase in the cost of the structure.

[0024] As shown in Figures 3 to 6, the sound-absorbing panel 10 is made up of divided bodies, that is, sound-absorbing panel divided bodies (hereinafter simply referred to as divided bodies), and is supported by appropriate means.
[0025] In the example shown in Fig. 4, one section is composed of eight divided bodies. Here, in Fig. 4, the divided body located at the upper left is referred to as upper left divided body 11LU, the divided body located at the upper right is referred to as upper right divided body 11RU, the divided body adjacent to the upper left divided body is referred to as upper left intermediate divided body 11LUM, the divided body adjacent to the upper right divided body is referred to as upper right intermediate divided body 11RUM, the divided body located at the lower left is referred to as lower left divided body 11LL, the divided body located at the lower right is referred to as lower right divided body 11RL, the divided body adjacent to the lower left divided body is referred to as lower left intermediate divided body 11LLM, and the divided body adjacent to the lower right divided body is referred to as lower right intermediate divided body 11RLM.
[0026] The number of segments is not limited to eight, but can be determined appropriately depending on the size of the area where it is to be installed.
[0027] Each of the divided bodies is placed on and supported by an end support member such as a beam B as described below. To support each divided body, a required number (three in the illustrated example) of hat-shaped support members (see FIG. 7) 30 are arranged between the beams B, B in the vertical direction in the figure, and a required number (one in the illustrated example) of inverted T-shaped support members 40 (see FIG. 8) are arranged between the beams B, B in the horizontal direction in the figure.

The left end of the upper left intermediate section 11LUM is placed on the flange 31 of the hat-shaped receiving member 30, the right end of the upper left intermediate section 11LUM is placed on the flange 31 of the hat-shaped receiving member 30, the upper end of the upper left intermediate section 11LUM is placed on the upper flange of the beam B which is an H-shaped steel, and the lower end is placed on the horizontal part 41 of the inverted T-shaped receiving member 40. The left end of the upper right intermediate section 11RUM is placed on the flange 31 of the hat-shaped receiving member 30, the right end of the upper right intermediate section 11RUM is placed on the flange 31 of the hat-shaped receiving member 30, the upper end of the upper right intermediate section 11RUM is placed on the upper flange of the beam B, and the lower end of the upper right intermediate section 11RUM is placed on the horizontal part 41 of the inverted T-shaped receiving member 40.
[0029] The left end of the left lower section 11LL is placed on the upper flange of the beam B which is an H-shaped steel, the right end of the left lower section 11LL is placed on the flange 31 of the hat-shaped receiving member 30, the upper end of the left lower section 11LL is placed on the horizontal part 41 of the inverted T-shaped receiving member 40, and the lower end of the left lower section 11LL is placed on the upper flange of the beam B. The right end of the right lower section 11RL is placed on the upper flange of the beam B which is an H-shaped steel, the left end of the right lower section 11RL is placed on the flange 31 of the hat-shaped receiving member 30, the upper end of the right lower section 11RL is placed on the horizontal part 41 of the inverted T-shaped receiving member 40, and the lower end of the right lower section 11RL is placed on the upper flange of the beam B. The left end of the lower left intermediate division body 11LLM is placed on the flange 31 of the hat-shaped receiving member 30, the right end of the lower left intermediate division body 11LLM is placed on the flange 31 of the hat-shaped receiving member 30, the upper end of the lower left intermediate division body 11LLM is placed on the horizontal portion 41 of the inverted T-shaped receiving member 40, and the lower end of the lower left intermediate division body 11LLM is placed on the upper flange of the beam B. The left end of the lower right intermediate division body 11RLM is placed on the flange 31 of the hat-shaped receiving member 30, the right end of the upper right intermediate division body 11RUM is placed on the flange 31 of the hat-shaped receiving member 30, the upper end of the lower right intermediate division body 11RLM is placed on the horizontal portion 41 of the inverted T-shaped receiving member 40, and the lower end of the lower right intermediate division body 11RLM is placed on the upper flange of the beam B.
[0030] The inside of the hat-shaped receiving member 30 is filled with sound-absorbing material M to prevent a decrease in the sound-absorbing effect. A filler-fall-out prevention plate 32 is disposed at the open end (the surface facing the room) of the hat-shaped receiving member 30. The filler-fall-out prevention plate 32 is preferably made of a decorative steel plate or a colored steel plate to enhance the aesthetic effect.
[0031] The heat insulating panel 20 is made of, for example, styrene foam and has a thickness of, for example, 25 mm. Since the heat insulating panel 20 is made of styrene foam, it can be longer than the sound absorbing panel 10, and both ends (front and rear ends in the illustrated example) in the longitudinal direction (front and rear direction in the illustrated example) are layered on the sound absorbing panel 10 while spanning the space between the ceiling beams B, B (see FIG. 3).
[0032] The soundproof sheet is provided by a known method.
[0033] Next, the application of the roofing material will be described with reference to Figs.
[0034] The tight frame is fixed to the tight frame receiving member 50 disposed on the upper end of the skeleton wall and the upper surface of the ceiling beam B (the upper flange of the H-shaped steel in the illustrated example). The fixing is performed by, for example, welding.
[0035] The tight frame receiving member 50 is, for example, a square pipe with rounded corners. The size of the square pipe is, for example, 75 mm square.
[0036] Next, the interlocking folded-plate roofing material is attached to the tight frame by a standard method. Here, a non-combustible sheet (non-combustible material) is attached to the inner surface of the interlocking folded-plate roofing material to improve fire resistance.
[0037] This completes the construction of the ceiling and roof.
[0038] Thus, according to this embodiment, the ceiling and roof can be constructed without erecting scaffolding inside the room.
[0039] In addition, since the sound-absorbing panel 10 is disposed on the surface facing the room, echoes within the room can be suppressed. Moreover, since decorative glass nonwoven fabric is disposed on the interior side of the sound-absorbing panel 10, the aesthetic appearance is improved. Furthermore, since the sound-absorbing panel 10 is made of glass wool, the increase in the weight of the ceiling can be minimized.
[0040] Although the present invention has been described above based on the embodiment, the present invention is not limited to only such an embodiment and various modifications are possible.
[0041] For example, in this embodiment, the roof is a folded plate roof, but the roof is not limited to a folded plate roof and may be another type of steel roof.
[0042] Furthermore, the thickness of the sound absorbing panel 10 and the thickness of the heat insulating panel 20 are appropriately determined depending on the required performance. [Industrial Applicability]
[0043] The present invention is applicable to the construction industry. [Explanation of symbols]
