Description

[Technical Field]

[0001] The present invention relates to an interior structure. [Background technology]

[0002] Metal-resin composite panels, in which a core material made of resin is sandwiched between a pair of metal surface plates, are known as surface finishing materials for walls and ceilings (see, for example, Patent Document 1). The composite panel in Patent Document 1 is attached to a base material via screws. When lightweight composite panels are used as surface finishing materials for interior partition walls and ceilings, the surface finishing material is sometimes attached to the base material via adhesive.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-302772 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, with the strengthening of earthquake resistance, there has been a demand for improved mounting strength for surface finishing materials in interior structures. Improving the mounting strength of surface finishing materials can prevent them from falling, further ensuring safety within the room. Furthermore, when surface finishing materials are fixed with adhesive, there is concern about the adhesive's deterioration over time. Furthermore, even with lightweight metal-resin composite panels, clients may request improved mounting strength. Furthermore, when metal-resin composite panels are attached to the base material using screws, the screws can become exposed, detracting from the aesthetic appearance.

[0005] From this perspective, the present invention aims to provide an interior structure that has high mounting strength for a surface finishing material, can prevent the surface finishing material from falling off, and has a good appearance and high design quality. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides a core material having a pair of Made of metal Sandwiched with face material Integrated with An interior structure comprising a metal resin composite panel and a base material to which the metal resin composite panel is attached with an adhesive, wherein a convex portion for screwing to the base material is provided on the peripheral portion of the metal resin composite panel, and the convex portion is A portion of the face material and the core material on the base material side protrudes outward in a rectangular shape from the linear side portion of the peripheral edge of the metal-resin composite panel. Consists of , with screw holes a recess for accommodating the protrusion is provided in a peripheral portion of the other metal-resin composite panel facing the protrusion, and the recess is formed by removing a part of the face material and the core material on the base material side; When viewed from the base material side, the recess has a rectangular shape larger than the convex portion, the depth dimension of the recess is larger than the thickness dimension of the convex portion, the screw hole is configured by connecting a small-diameter hole for the screw body formed in the face material with a large-diameter hole for the screw head formed in the core material, and the thickness dimension of the core material at the convex portion is equal to or larger than the thickness dimension of the screw head. It is characterized by:

[0007] According to the interior structure of the present invention, the metal-resin composite panel (surface finishing material) is attached to the base material with increased strength by fastening it to the convex portion with screws. Furthermore, even if the adhesive were to come off, the metal-resin composite panel is supported by the screws, preventing it from falling. Furthermore, because the convex portion is housed in the concave portion, the convex portion and the screws can be hidden when viewed from the front side. This makes the screws invisible on the interior surface, improving the aesthetic appearance of the interior structure and enhancing its design. In addition, the screw heads are contained within the convex portions without protruding from them, so they do not come into contact with the surface of the concave portions. Furthermore, fastening the screws to the base material provides high stability and increases the mounting strength of the metal-resin composite panel. [Effects of the Invention]

[0010] According to the wall structure of the present invention, the mounting strength of the surface finishing material is high, the surface finishing material can be prevented from falling off, and the aesthetic appearance can be improved. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0012] An interior structure according to an embodiment of the present invention will be described in detail with reference to the drawings. The structure according to the present invention is applied to the walls and ceilings of a room. In this embodiment, the interior structure will be described by taking as an example a case where the interior structure is applied to a wall of a room. As shown in FIG. 5, the interior structure 1 according to this embodiment includes a metal-resin composite panel 10 and a base material 30.

[0013] The metal-resin composite panel 10 is a surface finishing material for the interior structure 1 and has a rectangular shape. As shown in Figs. 1 and 2, the metal-resin composite panel 10 is constructed by sandwiching a core material 11 between a pair of face materials 12, 12. The metal-resin composite panel 10 has a thickness of, for example, 3 to 4 mm and a weight of 6 to 7.6 kg / m 2and is lighter than general surface finishing materials. The metal-resin composite panel 10 is attached to a base material (board) 30 via adhesive 2 and double-sided tape 3 (see FIG. 5). The base material 30 is a direct-attachment base made of a plate material such as plasterboard, flexible board, or calcium silicate board, or a lightweight steel frame material. In this embodiment, the base material 30 is made of a plate material. The base material 30 is fixed to a light-weight steel base material (a vertical member made of lightweight steel frame) 31 erected on the interior side of the room. The double-sided tape 3 is attached to the surface of the metal-resin composite panel 10 on the base material side, with a predetermined interval between them, on the frame. The adhesive 2 is applied to the inside of the double-sided tape 3. The metal-resin composite panels 10 are arranged vertically and horizontally, and joints 13 of a predetermined width (see FIG. 5) are formed between adjacent metal-resin composite panels 10.

[0014] The core material 11 is made of a resin with a relatively low specific gravity, such as polyethylene or foamed polyethylene, and has a thickness of 2 to 3 mm. The face material 12 is made of a metal, such as aluminum, stainless steel, titanium, galvalume, or steel, and has a thickness of approximately 0.5 mm. The face material 12 is integrated onto both sides of the core material 11. The outer surface of the core material 11 is subjected to a surface treatment to improve its appearance. The surface treatment may include, for example, a general-purpose paint (such as polyester resin paint), a highly weather-resistant paint (fluororesin paint), an antibacterial / anti-fungal paint, an antistatic paint, a primer treatment, or a mirror finish. When distinguishing between the indoor side and the base material 30 side, the face material 12 may be referred to as the "front panel" and the "rear panel."

[0015] As shown in FIGS. 1 to 4, the metal resin composite panel 10 has a protrusion 15 and a recess 25. The protrusion 15 is a portion for fastening the metal resin composite panel 10 to the base material 30 (see FIG. 5) with a screw and protrudes outward from the peripheral edge of the metal resin composite panel 10. In this embodiment, a single protrusion 15 is provided, protruding upward from the longitudinal middle of the upper edge of the metal resin composite panel 10. The protrusion 15 has a rectangular shape and has width and height dimensions that allow two screws V to be inserted therethrough. At least the face material 12 (back surface plate) on the base material 30 side protrudes in a quadrangular shape from the protrusion 15. In this embodiment, the protrusion 15 is configured such that the face material 12 on the base material 30 side and a portion of the core material 11 protrude. A portion of the core material 11 is a portion of the face material 12 on the base material 30 side and protrudes integrally with the face material 12. The protrusion 15 has two screw holes 16. The number of screw holes 16 is set appropriately depending on the weight of the metal resin composite board panel 10. In this embodiment, two screw holes 16 are formed, but if the weight of the metal resin composite board panel 10 is small, one screw hole may be provided, and if the weight of the metal resin composite board panel 10 is large, multiple screw holes may be provided.

[0016] The screw hole 16 is configured by a screw body hole 17a and a screw head hole 17b that are connected to each other. As shown in FIG. 4, the screw body hole 17a is a portion through which the body of the screw V to be inserted into the screw hole 16 passes, and is formed in the face material 12. The screw body hole 17a is a small-diameter hole that can accommodate the body of the screw V. Specifically, the diameter of the screw body hole 17a is larger than the diameter of the body of the screw V but smaller than the diameter of the head of the screw V. The screw head hole 17b is a portion that accommodates the head of the screw V to be inserted into the screw hole 16, and is formed in the core material 11. The screw head hole 17b is a large-diameter hole that can accommodate the head of the screw V (larger than the diameter of the head of the screw V). The thickness dimension of the core material 11 at the protrusion 15 (the depth dimension of the screw head hole 17b) is equal to or greater than the thickness dimension of the head of the screw V. As a result, the entire head of the screw V is accommodated within the screw head hole 17b, and the head of the screw V does not protrude from the surface of the protrusion 15.

[0017] The recess 25 is a portion that accommodates the protrusion 15 and is formed in the peripheral portion of another metal-resin composite panel 10 facing the protrusion 15. In this embodiment, the recess 25 is formed in the peripheral portion of one metal-resin composite panel 10 opposite the upper peripheral portion where the protrusion 15 is formed (lower side). The recess 25 is formed in one location, in the longitudinal middle portion of the lower edge of the metal-resin composite panel 10. The recess 25 is formed by cutting out a portion of the face plate 12 (back plate) and the core material 11 on the base material 30 side. The recess 25 is open on the base material 30 side and the bottom side, and has a rectangular shape that is slightly larger than the protrusion 15 when viewed from the base material 30 side. Specifically, the recess 25 has width and height dimensions that extend from both side edges and the upper edge of the protrusion 15 by a clearance equal to the joint width between the metal-resin composite panels 10. The clearance between the recessed portion 25 and the protruding portion 15 is not limited to the joint width, and may be smaller or larger than the joint width. The depth of the recessed portion 25 (the cutting depth in the thickness direction of the metal-resin composite panel 10) is larger than the thickness of the protruding portion 15.

[0018] In the metal-resin composite panel 10 configured as described above, the face material 12 (back surface material) on the base material 30 side has a convex portion 15 formed on the upper edge and a concave portion 25 formed on the lower edge. On the other hand, the face material 12 (front surface panel) on the indoor side has a rectangular shape.

[0019] To construct the interior structure 1 having the above configuration, after the base material 30 is installed, the metal-resin composite board panels 10 are attached to the base material 30 one by one, starting with the lower metal-resin composite board panel 10. Double-sided tape 3 is attached to the back surface of the metal-resin composite board panel 10 (the surface facing the base material 30), adhesive 2 is applied, and the metal-resin composite board panel 10 is pressure-attached to the base material 30 in a predetermined position. Then, screws V are driven into the upwardly protruding protrusions 15. At this point, the metal-resin composite board panel 10 is temporarily fixed by the screws V, so the retaining members of the metal-resin composite board panel 10 can be removed even before the adhesive 2 has hardened. Then, the upper metal-resin composite board panel 10 is attached using the same procedure. As a result, as shown in Figures 5 and 6, the protrusions 15 of the lower metal-resin composite board panel 10 are covered and hidden by the recesses 25 of the upper metal-resin composite board panel 10. As a result, a joint is formed between adjacent metal-resin composite board panels 10 when viewed from the interior side. The upper end of the metal-resin composite panel 10 installed at the upper end of the wall is located above the finished surface of the ceiling, and the protrusion 15 is not visible from inside the room.

[0020] According to the interior structure 1 of this embodiment, the metal-resin composite board panel 10 is attached to the base material 30 with the adhesive 2 and double-sided tape 3, and is then fastened with screws via the protrusions 15, which increases the attachment strength of the metal-resin composite board panel 10 to the base material 30. Furthermore, even if the adhesive 2 peels off during an earthquake or the like, the metal-resin composite board panel 10 is supported by the screws V, preventing it from falling.

[0021] Furthermore, when the metal resin composite panel 10 is used as a wall finishing material, the protrusions 15 protrude upward from the upper edge of the metal resin composite panel 10, so that even if the adhesive 2 peels off, the metal resin composite panel 10 is suspended and supported in a stable state, and the screws V only need to support the weight of the metal resin composite panel 10. This further increases the attachment strength of the metal resin composite panel 10 to the base material 30.

[0022] Furthermore, in this embodiment, the convex portion 15 is formed by protruding a portion of the face material 12 and core material 11 on the base material 30 side, and the concave portion 25 is formed by removing a portion of the face material 12 and core material 11 on the base material 30 side, so that the convex portion 15 is housed inside the concave portion 25. This makes it possible to hide the convex portion 15 and the screws V when viewed from the interior surface side. Furthermore, linear joints are formed between the metal-resin composite panels 10, 10, which improves the aesthetic appearance of the interior structure 1 and enhances its design.

[0023] Furthermore, screw hole 16 formed in convex portion 15 is configured by connecting small-diameter screw body hole 17a formed in face material 12 with large-diameter screw head hole 17b formed in core material 11, and because the thickness of core material 11 of convex portion 15 is equal to or greater than the thickness of the head of screw V, the head of screw V is accommodated within convex portion 15 without protruding from it. This means that the head of screw V does not come into contact with the surface of recess 25, allowing metal-resin composite panel 10 to be attached flat.

[0024] While the above describes embodiments of the present invention, the present invention is not limited to these embodiments, and appropriate design changes, such as material, shape, and size, are possible without departing from the spirit of the present invention. For example, in the above embodiment, the protrusion 15 is provided in a single location in the longitudinal middle of the upper edge of the metal-resin composite panel 10, but this is not limiting. Depending on the dimensions of the metal-resin composite panel 10, multiple protrusions may be provided on the upper edge, or one or more protrusions may be provided so as to protrude laterally from the side edge of the metal-resin composite panel 10. When a protrusion is provided on a side edge, a recess is formed at a symmetrical position on the opposite side edge.

[0025] In the above embodiment, the metal-resin composite panel 10 is used as a surface finishing material for the wall, and the interior structure 1 is applied to the wall of the room, but this is not limited to this. It is also possible to use the metal-resin composite panel as a ceiling panel, and apply the interior structure 1 to the ceiling. [Explanation of symbols]
