On the upper flange 12 of the structural member 1, a roof member 3 is constructed directly or through a supporting member such as a hanging member, a tight frame, rafters, etc. The structure may be a roof structure such as a horizontal roof or a folded plate, a solar cell panel, or a green structure, and the structure thereof is not particularly limited. In the embodiment of FIG. 1, a heat insulating metal fitting 41 is fixed to the upper flange 12 of the structural material 1, and a roof material 3 which is a vertically-folded folded plate is attached via a receiving material 42,
A cover material 5 was attached between the roof materials 3 and 3 to form a roof structure.

The roofing material 3 used in the embodiment shown in FIG. 1 is a vertical thatched plate having one valley portion (flat surface portion 31) and a molding portion 32 having mounting means on the left and right side edges. In general, surface decorative steel sheets of approximately 0.4 to 1.6 mm, stainless steel sheets, laminated steel sheets, rust-proof treated steel sheets such as hot dip galvanized steel sheets and galvalume steel sheets, special steel and non-ferrous metals, aluminum alloy sheets, lead sheets, A known metal material such as a zinc plate, a titanium alloy plate, or a copper plate is formed into a predetermined shape by roll forming, press forming, or other means. In particular, a relatively thick plate thickness of about 0.8 to 1.6 mm is preferable in order to secure positive and negative pressure strength as a surface.

The heat-insulating metal fitting 41 used in the embodiment of FIG. 1 is for integrally fixing the receiving member 42 to the upper flange 12.
A material which does not transfer (heat transfer) the heat from the receiving material 42, that is, the roof material 3 and the cover material 5 that constitute the roof surface to the upper flange 12, that is, the ceiling material 2 and the interior side is used.

The receiving material 42 used in the embodiment of FIG. 1 holds the roofing material 3, and the dimensions of the roofing material 3 which will be described later,
Depending on the required strength, etc., it is usually formed by pressing a stainless steel plate or plated steel plate of about 0.6 to 3.2 mm, etc., and has a U-shaped cross-section in which the front and rear symmetrically formed receiving parts stand upright. It is a molded piece material, and is joined to the heat insulating metal fitting 41 at the bottom surface portion. Attached means for elastically engaging (fitting) with the attaching means of the roof member 3 are provided on the left and right side edges of the receiving portion.

The cover member 5 used in the embodiment shown in FIG. 1 is made of the same material as the roof member 3 and is provided with attachment means for elastically fitting the roof member 3 on the left and right side edges.

In the embodiment shown in FIG. 1, the functional material 6 which is a negative ion generating building material is used as the lower flange 1 of the structural material 1.
It was installed between 3 and 13. Since the mounting portions 22a and 22b of the ceiling materials 2a and 2b are placed on the lower flange 13 as described above, when the functional material 6 is laid (placed) on the mounting portions 22a and 22b, the ceiling materials 2a and 2b are not attached. The mounting portions 22a and 22b are supported in a sandwiched manner from above and below. Further, the heat insulating material 7 is arranged above the functional material 6 (on the roof side) so as to cover the upper half of the structural material 1.

The functional material 6 used in the embodiment of FIG. 1 has a construction in which a building material is provided with a function of generating negative ions which emits negative ions to the inside of the room and a function of emitting far infrared rays which emits far infrared rays. Negative ions and far infrared rays generated from the functional material 6 are emitted and radiated to the inside of the room through the plurality of holes 211 formed in the ceiling material 2. Specifically, water-based paint containing acrylic acid copolymer emulsion as the main component (Fuquat FX manufactured by New Year's Futech Co., Ltd.)
In addition, 10 parts by weight of powdered carbon fiber (Tosca manufactured by Toray Industries, Inc.) as a conductive material is added to 100 parts by weight of the water-based paint, and 5 wt% of garnet and minerals such as zirconium, barium, lanthanum, cerium and neodymium are fired. 10 parts by weight of a mixed fine powder (average particle size: 5 μm) consisting of 95 wt% of an exciter composed of an oxide according to the above was added and sufficiently stirred and mixed to prepare a liquid composition. It was coated on (wood wool cement board) and dried sufficiently. In addition, the functional material 6 is a plate-shaped molded body having one or more characteristics selected from heat insulation, sound absorption, sound insulation, and fire resistance, and is glass wool,
Insulation material such as mat or board made of foamed resin,
Sound absorbing material, fireproof material, or various materials can be used,
It may be made of a single material or a laminate of different materials, and may be hard or soft, and its thickness may be set appropriately.

The heat insulating material 7 used in the embodiment of FIG. 1 is made of a water impermeable material, and has one ridge portion 71 and flat portions 7 on the left and right side edges.
Although it is preferable that the structure including 2 is made of a single water-impermeable member, if the surface layer is a water-impermeable material, another material may be laminated on the back surface side (inside the room). As the heat insulating material 7 composed of a single non-water-permeable member, a known non-water-permeable material mainly composed of a foamed (independent foaming) resin such as relatively hard foam polystyrene or polyurethane foam can be used. For example, a structure in which a water-impermeable foamed resin material is laminated on the front surface side and a foamed (continuous foamed) resin material capable of absorbing water (holding water) is laminated on the back surface side (inside the room) may be laminated.
Then, on the mountain portion 71 of the heat insulating material 7, the adjacent roof material 3,
The side edges of 3 were laid on the back surface (lower surface) of the valley portion (flat surface portion 31) of the roofing material 3 with the side edges (connecting portions) of the adjacent heat insulating materials 7, 7 positioned respectively. Therefore, the side edge of the roofing material 3 and the side edge of the heat insulating material 7 will be arrange | positioned in the position shifted | deviated in the vertical direction, and even if rainwater infiltrates from the side edge of the roofing material 3, infiltration water will be It does not reach the side edge and does not go around to the back side (lower side) of the heat insulating material 7. Further, since the roofing material is not constructed in double and the heat insulating material is interposed between the inner and outer roofing materials, it is economically excellent. Further, a drainage groove 73 is formed on the front surface side of the heat insulating material 7 of the illustrated embodiment so as to prevent water from flowing from the side edge to the back surface (lower surface). In addition, since the adjacent heat insulating materials 7, 7 are provided with a polymerized portion 721 and a polymerized portion 722 capable of polymerizing, and a space portion 723 for drainage is formed in the polymerized portion obtained by polymerizing these, Drain 73 and space 7
In No. 23, extremely high rain terminating performance is exhibited, and rainwater does not reach the back surface side (lower surface side = indoor side) of the heat insulating material 7.

Although not shown, a plurality of wires, T-joiners, steel rods, flat bars, etc. are appropriately used as receiving materials on the lower surface (inside the room) or the upper surface (on the roof side) of the functional material 6, or both. Place at intervals, wire mesh, punching metal, mesh (fall prevention net), etc.,
By using these in combination, the functional material 6 and the heat insulating material 7 may be prevented from bending, deforming, dropping, and the like.

In the ceiling / roof structure of FIG. 1 constituted by such members, after the structural material 1 is arranged at appropriate intervals, the ceiling material 2 and the functional material 6 are attached to the lower flange 13 of the structural material 1. Installation, then the upper flange 12 of the structural material 1 on the heat insulating fitting 4
1 is fixed, the heat insulating material 7 is arranged, and the heat insulating metal fitting 41 is provided with the receiving material 4
2 is attached, the roofing material 3 is further laid, and the cover material 5 is attached, and it is constructed. Since the roof construction and the ceiling laying construction can be performed together, the construction period can be shortened. In addition, since the structural material 1 is used as a combined member for the roof and the ceiling and does not require a separate member for constructing a ceiling on the back side (inside the room) of the roof structure as in the conventional structure, the number of members is greater than that in the conventional structure. Less, material cost,
Material management is easy. Further, the decorative portion 21 of the ceiling material 2
Since a large number of holes 211 are formed in the interior, it has excellent sound absorption performance, and when a negative ion generating building material or far-infrared radiation material is arranged on the back surface (inside the room), its emission or radiation is prevented. It can be supplied indoors without hindrance.

In particular, in the embodiment shown in FIG. 1, since the symmetrical ceiling members 2a and 2b are used, there should be no mistake in the arrangement direction. Further, since the breathable sheet material 23 is attached to the rear surface side (outdoor side) of the decorative surface, the functional material 6 arranged on the outdoor side of the ceiling material 2 cannot be seen from the indoor side through the hole portion 211 ( (Blindfold), and further, dust and dirt such as wood wool generated from the functional material 6 do not fall through the hole portion 211 to the indoor side.

In the embodiment shown in FIG. 2, the valley-shaped decorative portion 2 is used.
Ceiling material 2c having 1c and flat-shaped decorative portion 21b
Since the ceiling material 2b having the above is used in combination in an alternating manner, it is almost the same as the embodiment of FIG.

Each of the embodiments shown in FIGS. 3 to 5 shows a variation of the ceiling design. In FIG. 3, only one type of ceiling material 2d having a curved decorative portion 21d is used, and in FIG. Using only one type of ceiling material 2e having the decorative portion 21e of FIG. 5, two types of the ceiling material 2f having the mountain-shaped makeup portion 21f and the ceiling material 2g having the valley-shaped makeup portion 21g are alternately combined in FIG. Using. The makeup parts 21f, 21
The tapered surface formed in g is formed and connected as if it were continuous. Therefore, in FIG. 3, a decorative surface having a design in which curved surfaces are connected is formed, in FIG. 4, a decorative surface having a short wave (zigzag) design is formed, and in FIG. A decorative surface having a (zigzag) design is formed. In this way, the design of the decorative surface may be formed of one kind of ceiling material or may be created by combining two kinds (or three or more kinds) of different shapes. The design can be obtained. Also, these ceiling materials 2d to 2g
All the mounting portions 22d to 22g of the lower flange 1 are bent along the lower surface of the lower flange 13 of the structural material 1 and the tip thereof is folded back.
Since the structural material 1 cannot be seen completely from the indoor side, the design of the ceiling is further improved because the structural material 1 cannot be seen completely from the indoor side. Other than the above, it is almost the same as the embodiment of FIG. 1, so the same reference numerals are given to the drawings and the description is omitted.

In the embodiment shown in FIG. 6, the square wave-shaped decorative portion 2 is used.
Although only one kind of ceiling material 2h having 1h is used, the direction of forming the square wave-shaped decorative surface is a direction (front and rear in the drawing) orthogonal to the longitudinal direction of the structural material 1 (left and right in the drawing). Direction). That is, in this embodiment, since the structural material 1 is laid in the lateral direction orthogonal to the inclination of the roof, the direction of forming the angular wavy decorative surface is the direction along the inclination of the roof. In this way, when a square wave-shaped decorative surface (also in the case of forming a curved decorative surface) is formed in a direction intersecting the length direction of the structural material 1, the strength can be improved and the function can be provided immediately above. Even if the sex material 6 is placed, it can be supported. Further, in this embodiment, the upper flange 1 of the structural material 1 is
2, a running water member 43 and a suspender 44 are fixed by a fixture 45 through a base material 7 ′ such as a wood wool cement plate, and a roofing material 3 which is a vertically roofed exterior material with respect to the suspender 45. ′ Is attached, a heat insulating material (backup material) 7 ″ is arranged on the back side (lower side) thereof, and a cover material 5 ′ that covers between the adjacent roof materials 3 ′ and 3 ′ is attached.

Each of the embodiments shown in FIGS. 7 and 8 shows a variation of the mounting method of the ceiling material 2. In FIG. 7, the asymmetrical (different shape) mounting is applied to the left and right side ends of the flat decorative portion 21i. Ceiling material 2i having parts 22ia and 22ib
The one mounting portion 22ia is formed with a cover portion that visually hides the lower flange 13 of the structural material 1 from the indoor side, and a horizontal piece that is folded back is placed on the lower flange 13. The other mounting portion 22ib is a flat-shaped decorative portion 21i, the side end of which is folded upward, and a horizontal piece of which the material is extended outward is placed on the lower flange 13 and screwed. . In FIG. 8, the ceiling material 2j is used in which the mounting portions 22j are formed at the left and right side ends of the curved decorative portion 21j, and the mounting portion 22j is formed with an engaging piece that is folded inward at the upper end of the vertical piece. Then, the engaging piece is inserted from the gap of the rising portion 11 of the structural material 1 and locked (hooked) in the opening portion 111 to be attached.

Although the present invention has been described based on the embodiments of the drawings, the present invention is not limited to the above embodiments, and may be modified in any manner as long as the configuration described in the claims is not changed. It can be carried out.

[0029]

As described above, in the ceiling / roof structure of the present invention, the roof construction and the laying construction of the ceiling can be carried out together, so that the construction period can be shortened. Also,
Since the structural material is used as both roof and ceiling members, and there is no need for a separate member for constructing the ceiling on the back side (inside the room) of the roof structure as in the past, the number of members is smaller than in the past, Material cost and material management are easy.

In particular, when a breathable material is adhered to the back surface (outdoor side) of the ceiling material, the functional material or the like arranged on the outdoor side of the ceiling material becomes invisible from the indoor side through the hole (blindfold), and further functions. It is possible to prevent dust and dirt such as wood wool generated from the elastic material from falling through the hole to the indoor side.

Further, between the lower flanges of the adjacent structural members,
When a functional material having one or more characteristics selected from negative ion generation, heat insulation, sound absorption, sound insulation, and fire protection is installed, various characteristics of the functional material are exerted on the indoor side and the ceiling is attached to the lower flange. In the mode in which the mounting portion of the material is placed, the function of suppressing the mounting portion by the edge of the functional material is also fulfilled.
