Description

TECHNICAL FIELD The present invention relates to drywall materials forming the interior or exterior of buildings and structures.

In general, there are many exterior materials on the market that are made by processing metal plates by roll forming, press forming, etc., and forming irregularities on the decorative surface. (For example, see Patent Documents 1 and 2).

Patent No. 5882782 JP2009-281075A

Patent Document 1 relates to a "building board used as an exterior material, etc." and uses a wooden board or a metal board, and has a linear pattern formed approximately horizontally, so that the short ends of the building board are adjacent to each other. This has the effect of making the seam less noticeable. Patent Document 2 relates to a "wall structure using metal siding," and describes the use of metal siding having a design in which decorative recesses that are substantially rectangular in plan view are staggered without facing each other across joint grooves. .

However, Patent Documents 1 and 2 place emphasis on making the connection less noticeable by embossing or printing the decorative surface of the metal plate material or by devising the arrangement of recesses, resulting in a monotonous design. was.

In order to eliminate such drawbacks, the present invention has been developed to provide a horizontally long and elongated material in which a core material is formed between the metal surface material and the back surface material, and a male-female connection structure is formed at the upper and lower ends of the metal surface material. In drywall materials, a plurality of horizontal joints forming a three-sided structure consisting of an upper inclined surface, a bottom surface, and a lower inclined surface are formed on the decorative surface of the metal surface material, and the decorative surface is divided by the horizontal joints. The surface forms a multi-step block consisting of a plurality of inclined surfaces and planes formed from a plurality of convex portions perpendicular to the horizontal joint, and the convex portion has a length H in the width direction and a length H in the longitudinal direction. A drywall material characterized in that H>W always holds in relation to the width W, and the inclined surfaces and flat surfaces of the same shape are not lined up in the vertical direction and have irregular irregularities.

According to the drywall material according to the present invention, (1) the plurality of horizontal joints makes it possible to make connecting joints between exterior materials inconspicuous, and it is possible to create a sense of unity in the design of the exterior materials. (2) Different impressions can be created depending on the construction method, vertically or horizontally. (3) Since the convex texture formed on the blocks of each stage is inclined in the lateral and longitudinal directions of the exterior material, shadows are likely to appear in any construction method. It has the following characteristics and effects.

An embodiment of the drywall material according to the present invention will be described in detail below with reference to the drawings. The drywall material A is a drywall in which a core material 3 is filled between a metal surface material 1 and a back surface material 2, as shown in FIGS. 1, 2(a), (b), 3, and 4. It is material A. For example, the metal surface material 1 and the back surface material 2 are made of thin metal plates, and the core material 3 is made of synthetic resin foam. Moreover, FIG. 3 is a diagram showing the construction state, where α is the frame, β is the fixture, and γ is the connecting joint. Note that FIGS. 1 to 3 do not show the uneven pattern (embossed pattern) on the decorative surface 6 portion, and the details are shown in FIG. 5.

The metal surface material 1 and the back material 2 are made of, for example, iron, aluminum, copper, stainless steel, titanium, aluminum/zinc alloy plated steel sheet, enameled steel sheet, clad steel sheet, (PVC steel sheet, etc.), sandwich steel sheet (vibration damping steel sheet, etc.), or chlorinated steel sheet. It is made by embossed roll molding or press molding of a type of vinyl resin, polycarbonate resin, etc. (of course, including color plates coated with these resins in various colors). In addition, as the backing material 2, aluminum vapor-deposited paper, kraft paper, asphalt felt, metal foil (Al, Fe, Pb, Cu), synthetic sheet, rubber sheet, cloth sheet, gypsum paper, aluminum hydroxide paper, glass fiber nonwoven fabric, etc. It may also be a laminate of one or more of these, or a sheet-like material that has been treated with waterproofing or flame retardant treatment.

The core material 3 is made of synthetic resin foam such as polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam, urea foam, etc., and the metal surface material 1 or the back material 2 The metal surface material 1 or the back surface material 2 is integrally formed by discharging it onto the back surface side and heating it to react and harden it. In addition, the core material 3 contains various flame retardant materials such as lightweight aggregates (perlite grains, glass beads, gypsum slag, talcum, shirasu balloons, aluminum hydroxide, etc.) and fibrous materials (glass wool, rock wool, carbon fiber, etc.). , graphite, etc.) to improve fire resistance and fire protection.

The drywall materials A are connected to each other as shown in FIG. 3 by connecting the engaging pieces 10 to the fitting grooves 16 and the fitting pieces 14 to the engaging grooves 11.

As an example of the overall shape of the drywall material A, as shown in FIGS. 1, 2(a) and 2(b), there is a core between the metal facing material 1 and the backing material 2 made of long thin metal plates. The material 3 is sandwiched and formed from a male connecting part 4 formed at one end in the width direction and a female connecting part 5 formed at the other end, with a lower wall 7 at the lower end of the decorative surface 6 and an upper wall at the upper end. 8.

More specifically, the male connecting portion 4 includes a lower wall 7 with the lower end of the decorative surface 6 bent toward the back side, a horizontal joint bottom surface 7a with the tip of the lower wall 7 hanging downward, and a horizontal joint bottom surface 7a with the tip of the horizontal joint bottom surface 7a facing the back side. The upper surface 7b is folded back and the tip extends upward, the protruding piece 9 consists of the horizontal joint bottom surface 7a and the upper surface 7b, and the engaging piece 10 with the tip of the upper surface 7b hanging downward on the back side engages with the upper surface 7b. It is formed from an engagement groove 11 consisting of a piece 10. Note that P is a packing formed to enhance waterproofness.

The female connecting portion 5 includes an upper wall 8 with the upper end of the decorative surface 6 bent toward the back side, a step 12 with the tip of the upper wall 8 bent further toward the back side, and a joint bottom surface 8a with the step 12 projecting upward. , a lower surface 13 with the tip of the joint bottom surface 8a bent downward on the back surface side, a fitting piece 14 made up of the joint bottom surface 8a and the lower surface 13, a fixed surface 15 projecting by bending the tip of the bottom surface 13 upward, and the lower surface 13. It is formed from a fixing surface 15 and a fitting groove 16 formed from the fixing surface 15.

As shown in detail in FIGS. 4 to 6 , the decorative surface 6 has a convex portion 18 projecting convexly toward the surface side with respect to the decorative surface 6, and a trapezoidal concave portion extending in the longitudinal direction as shown in FIG. It consists of horizontal joints 17 that cross.

As shown in FIG. 4, the horizontal joint 17 is formed from an upper inclined surface 17a, a lower inclined surface 17b, and a bottom surface 17c, which is formed from a lower wall 7, a lower horizontal joint bottom surface 7a, and an upper wall 8. Like the connecting joint γ, it is composed of three sides, so it has the effect of making the connecting joint less noticeable.

The block 19 is a decorative surface partitioned by the horizontal joints 17.

Assuming that the length of the block 19 in the short direction is H and the width of the block 19 in the longitudinal direction is W, the length and width of each convex part 18 always satisfy H>W as shown in FIG. . Furthermore, the convex portions 18 consisting of the right inclined surface 18a, the left inclined surface 18b, and the flat surface 18c do not have the same width or inclination in the same block 19 .

The number of stages of the block 19 does not need to be three as long as the relationship H>W of the convex portion 18 is maintained.

FIG. 6 is a sectional view of the decorative surface 6 viewed from a plane parallel to the horizontal joints 17 . A convex portion 18 is formed on the decorative surface 6 and includes a right inclined surface 18a, a left inclined surface 18b, and a flat surface 18c inclined in the transverse direction, each of which is randomly combined. By doing so, it is possible to create a complex impression that is not monolithic.

The large number of small convex portions 18 on the decorative surface 6 can diffusely reflect sunlight, and can create different impressions depending on the construction method, vertically or horizontally.
