  Patent Documents 1 to 3 are drop-in structures, which are dry wall materials or building panels having irregularities on the decorative surface. Although Cited Document 1 aims to make the external shape of the connecting part the same as the external shape of the surface plate, the dimensions of the fitting part are required to be accurate. It was difficult to make the appearance of the connecting portion look the same as the appearance of the surface plate. Of course, the citations 2 and 3 are the same, and a gap is generated between the connecting portions, the connecting portion and the surface uneven shape are distinguished from each other, and the appearance is such that the unevenness is interrupted in the middle, and there is a sense of incongruity.

  In order to solve such drawbacks, the present invention is a long exterior material having a substantially vertical flat decorative surface and a male-female connecting structure at the upper and lower ends of the decorative surface. A lower side wall bent to the side, an inclined piece protruding with the tip of the lower wall inclined upward to the back side of the decorative surface, a protrusion protruding between the lower wall and the inclined piece to the back side, and the tip of the inclined piece A male connecting portion is formed from an engaging piece bent downward and an engaging groove made of an inclined piece and an engaging piece, an upper wall bent to the back side at the upper end of the decorative surface, and a tip of the upper wall And a female connecting portion that includes a fixed surface that protrudes downward by folding the tip of the joint ground, and a fixed surface that protrudes upward from the tip of the vertical surface. Formed, and when the exterior members are connected to each other, the engaging piece and the upper surface are in surface contact, and the projection and the ground are in line contact. It relates to wood.

  According to the exterior material according to the present invention, when the exterior materials are connected to each other, the engagement piece and the upper surface are in surface contact with each other, and the exterior material in which the protrusion and the ground are in line contact is formed (1) fitting The resistance at the time has been reduced so that it can be easily constructed. (2) When connecting exterior materials, even if the dimensions of the fitting part are slightly different, there is no possibility that the male connection part and female connection part can no longer be fitted and the workability is improved. At the same time, there will be no claims of poor fitting. (3) The waterproofness is improved by preventing the capillary phenomenon due to the gap formed in the fitting portion. There are features and effects.

  Hereinafter, an embodiment of an exterior material according to the present invention will be described in detail with reference to the drawings. That is, the exterior material A is an exterior material A in which a core material 3 made of, for example, a synthetic resin foam is sandwiched between a front surface material 1 and a back surface material 2 as shown in FIGS. . Moreover, FIG. 3 is sectional drawing which shows a construction state.

  As an example of the overall shape of the exterior material A, as shown in FIGS. 1, 2 (a) and 2 (b), a core material 3 is sandwiched between a surface material 1 and a back material 2 made of a long, thin metal plate. And formed with a male connecting portion 4 formed at the lower end in the width direction and a female connecting portion 5 formed at the upper end, and a lower side wall 7 formed at the lower end of the decorative surface 6 and an upper side wall 8 formed at the upper end. It is.

  More specifically, the male connecting portion 4 includes a lower side wall 7 in which the lower end of the decorative surface 6 is bent toward the back side, and an inclined piece 9b that protrudes by inclining the tip of the lower side wall 7 upward toward the back side of the decorative surface 6. In addition, a hanging surface 9 composed of a projection 9a protruding between the lower wall 7 and the inclined piece 9b toward the back surface side, a space 9c formed by the projection 9a and the inclined piece 9b, a hanging surface 9 and the engaging piece 10 It is formed of folded pieces 11a that connect between each other, and engaging grooves 11 that are formed by the lower hanging surface 9, the engagement pieces 10, and the folded pieces 11a.

  The female connecting portion 5 has an upper wall 8 in which the upper end of the decorative surface 6 is bent toward the back surface, a joint surface 12 in which the tip of the upper wall 8 is bent upward, and the tip of the joint surface 12 is inclined upward to the back surface side. The inclined surface 13 projecting upward, the upper hanging surface 14 that bends the tip of the inclined surface 13 and projects downward, the folded piece 15 a that connects the inclined surface 13 and the upper hanging surface 14, the inclined surface 13 and the upper surface A fitting piece 15 composed of the hanging surface 14 and the folded piece 15 a, a fixed surface 16 that protrudes by bending the tip of the upper hanging surface 14 upward, and a fitting composed of the upper hanging surface 14 and the fixing surface 16. The groove 17 is formed. In addition, 18 is a packing formed for waterproofing reinforcement | strengthening.

In FIG. 3, α is a housing, β is a fixture, and γ is a connecting portion.

  The surface material 1 and the back material 2 are thin metal plates such as iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel plate, galvalume steel plate, enamel steel plate, clad steel plate, laminated steel plate (vinyl chloride steel plate, etc.), sandwich steel plate (control) Corrugated steel sheets, etc.), vinyl chloride resin, polycarbonate resin, etc. (including color plates coated with various colors, of course) formed into various shapes by roll molding, press molding, extrusion molding, etc., or inorganic materials Are formed into various arbitrary shapes by extrusion molding, press molding, autoclave nurturing and the like. Also, as the back material 2, aluminum vapor-deposited paper, kraft paper, asphalt felt, metal foil (Al, Fe, Pb, Cu), synthetic resin sheet, rubber sheet, cloth sheet, gypsum paper, aluminum hydroxide paper, glass fiber nonwoven fabric Or a laminate of two or more kinds, or a sheet-like material that has been waterproofed or flame-retardant treated.

  The core material 3 is made of a synthetic resin foam such as polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam, urea foam, etc., and particularly when fire resistance is required. Is formed by mixing a stock solution of a resol type phenol, a curing agent, and a foaming agent, discharging the mixture onto the back surface side of the surface material 1 or the back material 2, and heating to react, foam and cure. In addition, the core material 3 includes lightweight aggregates (perlite grains, glass beads, gypsum slag, talc stone, shirasu balloon, aluminum hydroxide, etc.), fibrous materials (glass wool, rock wool, carbon fiber, Graphite and the like) can be mixed to improve fire resistance and fire resistance. Of course, an inorganic material such as rock wool, glass wool or ceramic wool may be used as the core material 3.

  The exterior materials A are connected as shown in FIG. 3 by the engagement piece 10 being connected to the engagement groove 17 and the engagement piece 11 being connected to the engagement groove 11.

  As shown in FIGS. 3, 7, and 8, the protrusion 9 a makes line contact with the joint ground 12, and prevents the hanging surface 9 and joint ground 12 from making surface contact when connecting the exterior materials A to each other. The resistance at the time of fitting is reduced so that it can be easily constructed. In other words, if the width between the engaging piece 10 and the protrusion 9a is h1, and the width between the joint surface 12 and the upper hanging surface 14 is h2, the protrusion 9a is in line contact with the joint surface 12, so that h1 is formed wide. Even if h2 is not formed narrowly, the exterior materials A can be easily fitted to each other and the workability is improved, and there is no claim of poor fitting between the exterior materials A.

  In actuality, although h1> h2, the gap between the projection 9a and the ground plane 12 can be minimized because h1 = h2 can be as close as possible. It is difficult to determine where the fitting portion that is a connecting portion between each other is present, and it is possible to form an exterior made of a single exterior material A that does not have a discontinuity in the joint portion.

  As shown in FIG. 8, the inclined piece 9b forms a space 9c in the engagement groove 11 and forms a gap 9d in the fitting portion to prevent capillary action and improve waterproofness. Further, the inclined piece 9b comes into contact with an inclined surface 13 of the female connecting portion 5 to be described later, so that the folded piece 15a at the tip of the fitting piece 15 further bites into the packing 18 due to the inclination and reinforces waterproofing. .

  As shown in FIGS. 7 and 8, the upper hanging surface 14 and the engagement piece 10 are in surface contact with each other to improve the connection strength between the exterior materials A.

Further, the inclined surface 13 formed at the tip portion of the basement base 12 is formed so as to be in surface contact with the inclined piece 9b. In other words, the angle between the inclined piece 9b and the engagement piece 10 is θ1, the angle between the inclined surface 13 and the upright surface 14 is θ2, and the relationship between θ1 and θ2 is θ1 = θ2. The inclined surface 13 is formed so as to come into surface contact. In addition, the inclined surface 13 has an effect that the inclined surface comes into contact with the projection 9 a as shown in FIGS. 5 and 6 and the fitting piece 15 can be smoothly inserted into the engaging groove 11.

In this case, the upper surface 14 and the engagement piece 10 are in surface contact as shown by the dotted arrow A in FIG. 8, the projection 9a and the ground 12 are in line contact as shown by the one-dot chain arrow A, and the dotted arrow As shown in FIG. 4, the inclined piece 9b and the inclined surface 13 are formed so as to be in surface contact with each other, and the connecting portion has a structure excellent in workability, waterproofness and airtightness.

  Then, the construction order of the exterior material A is demonstrated using FIGS. 3-8. First, as shown in FIG. 4, the fixing surface 16 of the lower packaging material A <b> 1 is driven and fixed by the fixing tool β. Thereafter, as shown in FIGS. 5 to 7, the engaging piece 10 of the upper packaging material A <b> 2 is dropped into the fitting groove 17 of the lower packaging material A <b> 1, and as shown in FIGS. 3 and 8, the upper packaging material A <b> 2 is inserted. The fixing surface 16 of the exterior material A2 is placed on the housing α by a fixing device β. Construction is completed by performing such a process from the foundation to the eaves. Of course, in the case of vertical stretching, the exterior material A is constructed by sequentially performing the above steps in the horizontal direction.

  What has been described above is only one example of the exterior material according to the present invention, and the exterior material A may be formed as shown in FIGS. 9 (a) to 9 (f) to 11 (a) to 11 (f). I can do it.

  That is, FIGS. 9 (a) to (f) to FIGS. 11 (a) to (f) show the exterior material A in which the decorative surface 6 is deformed, 6a being a concave portion and 6b being a convex portion.

10 (a) to 10 (c), the exterior material A is formed so that the recess 19 is formed in the joint 12 and the projection 9a is fitted in the recess 19, and FIGS. 10 (d) to 10 (f).
