  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  The building panel according to Embodiment 1 is a so-called sandwich panel, and is used particularly for an outer wall of a building. As shown in FIG. 1, the building panel of the present embodiment includes a panel main body 1 and an attachment member 97 for attaching the panel main body 1 to a building frame.

  In the following, for convenience of explanation, the width direction of the panel body 1 is defined as the width direction of the panel body 1 (arrow A in FIG. 3), and the direction perpendicular to the width direction and along the panel body 1 (see FIG. 3) Arrow B) is defined as the longitudinal direction.

  As shown in FIG. 1, the panel body 1 includes an indoor side metal skin 11 facing the indoor side, an outdoor side metal skin 12 facing the outdoor side, the indoor side metal skin 11 and the outdoor side metal skin 12. And the core material 4 disposed between the two.

  The indoor side metal skin 11 and the outdoor side metal skin 12 are formed, for example, by rolling or bending a metal plate having a thickness of about 0.5 to 0.8 mm. The metal plate as a base material for the indoor side metal skin 11 and the outdoor side metal skin 12 is composed of a galvanized steel plate, a coated steel plate, a Galvalume steel plate (registered trademark), a stainless steel plate, or the like.

  As shown in FIG. 2, the indoor-side metal skin 11 includes an indoor-side main body 110 that forms an indoor side surface, and a first indoor-side connecting portion 111 that is formed at one end in the width direction of the indoor-side main-body 110. And a second indoor side connection portion 112 formed at the other end in the width direction of the indoor side main body portion 110.

  The indoor side main body 110 of the indoor side metal skin 11 is provided with reinforcing ribs 15 protruding from the surface on the core member 4 side so as to continue along the longitudinal direction. A plurality of the reinforcing ribs 15 are arranged side by side so as to be arranged in the width direction. As shown in FIG. 1, the reinforcing rib 15 has a predetermined gap between the projecting tip and the outdoor side metal skin 12 and is not in contact with the outdoor side metal skin 12 (for example, the panel thickness is Rib height is 14 mm for 50 mm). The plurality of reinforcing ribs 15 are parallel to each other over the entire length in the longitudinal direction. The reinforcing rib 15 of the present embodiment is formed so that the indoor side metal skin 11 is bent further toward the core material 4 side, and is further folded back so as to be convex toward the core material 4 side. As a result, a streak-like groove portion 17 is formed on the surface of the indoor side metal skin 11 facing the indoor side at a portion corresponding to the back surface of the reinforcing rib 15. The groove portion 17 of the present embodiment is continuous over the entire length in the longitudinal direction, and a plurality of the groove portions 17 are arranged in the width direction. In addition, one reinforcing rib 15 forms a reinforcing plate housing recess 16 with the other reinforcing rib 15 facing and the surface of the indoor side metal skin 11 on the core material 4 side. As shown in FIG. 2, the reinforcing plate accommodation recess 16 may be a recess in which the reinforcing plate material 5 is accommodated, and is an end of the indoor side main body 110 on the first indoor side connecting portion 111 side. A portion that is not sandwiched between two reinforcing ribs 15 such as a portion is also referred to as a reinforcing plate accommodating recess 16.

  In the reinforcing plate housing recess 16, the opposing dimension between the reinforcing ribs 15 is constituted by two types of dimensions, a first dimension L1 and a second dimension L2. The dimension between the reinforcing ribs 15 of the reinforcing plate housing recess 16 is the first dimension L1 (for example, 80 mm) in the reinforcing plate housing recess 16 to which the reinforcing tool 7 having a substantially U-shaped cross section described later is mounted. In the reinforcing plate accommodation recess 16 in which the reinforcing tool 7 is not mounted, the second dimension L2 (for example, 70 mm) is set. The first dimension L1 of the reinforcing plate housing recess 16 to which the reinforcing tool 7 is attached is formed wider than the second dimension L2, and both are different to the extent that the operator can visually discriminate them. It is a dimension.

  The outdoor-side metal skin 12 includes a substantially flat outdoor-side main body 120, a first outdoor-side connecting portion 121 formed at one end in the width direction of the outdoor-side main-body 120, and the width direction of the outdoor-side main-body 120. 2nd outdoor side connection part 122 formed in the other end.

  As shown in FIG. 1, the core member 4 includes a reinforcing plate member 5 disposed between the plurality of reinforcing ribs 15 along the indoor side metal skin 11, and a fireproof heat insulation layered on the outdoor side of the reinforcing plate member 5. The reinforcing plate material 5 and the refractory heat insulating material 6 have a two-layer structure. The reinforcing plate 5 is formed in a long rectangular shape, and is arranged so that the longitudinal direction thereof is the same as the longitudinal direction of the panel body 1. The reinforcing plate member 5 is accommodated in the reinforcing plate accommodating recess 16 by the back surface of the reinforcing plate member 5 being bonded and fixed between the pair of reinforcing ribs 15 to the indoor side metal shell 11.

  The reinforcing plate member 5 of the present embodiment is composed of an inorganic plate 51 as a refractory material. The inorganic board 51 has fire resistance equivalent to or higher than that of the fireproof heat insulating material 6 (for example, rock wool). For example, gypsum (gypsum board) mainly composed of calcium sulfate hydrate, calcium silicate, and the like. Etc. The inorganic plate 51 is formed so that the thickness thereof is substantially the same as or slightly thicker than the protruding height of the reinforcing rib 15 (for example, about 15 mm), and the rigidity is higher than that of the refractory heat insulating material 6. . The reinforcing rib 15 does not protrude from the surface of the inorganic plate 51 on the outdoor side metal skin 12 side.

  As shown in FIG. 4, a plurality of reinforcing plate members 5 of the present embodiment are arranged in parallel in the width direction. Each of the reinforcing plate members 5 is positioned so that both end surfaces in the longitudinal direction are shifted from both end surfaces in the longitudinal direction of other inorganic plates 51 adjacent in the width direction so that the end surfaces do not overlap each other when viewed in the width direction. Has been placed.

  In this way, the reinforcing plate member 5 is disposed so as to cover substantially the entire surface of the indoor side metal skin 11 on the core member 4 side. That is, a fireproof layer is formed by the plurality of reinforcing plate members 5 laid on substantially the entire surface of the indoor side metal skin 11 on the core material 4 side.

  In addition, this reinforcing board material 5 may replace the inorganic board 51 as a refractory material like this embodiment, and may use the heat insulating material which has rigidity. Examples of the heat insulating material include a highly rigid heat insulating board such as a styrene board, Styrofoam (registered trademark), a ceramic board, and the like. Thus, although the fireproof layer is formed in the surface by the side of the core 4 of the indoor side metal shell 11 of the building panel of Embodiment 1, in the building panel of this invention, the core of the indoor side metal shell 11 is formed. You may comprise a heat insulation layer by arrange | positioning a heat insulating material so that substantially the whole surface of 4 side may be covered.

  As shown in FIG. 1, the refractory heat insulating material 6 is composed of a plurality of refractory heat insulating blocks 61 cut into rectangular blocks. The fireproof and heat insulating block 61 of the present embodiment is made of an inorganic fiber material 62, specifically, rock wool. The refractory heat insulating material 6 is accommodated and disposed in a gap between the surface on the outdoor side metal skin 12 side of the reinforcing plate 5 and the outdoor side metal skin 12. The refractory heat insulation block 61 is arranged such that the fiber direction thereof faces in a direction perpendicular to both the metal shells 11 and 12.

  The fireproof and heat insulating block 61 of the present embodiment includes a first block 63 formed of a certain module, and a second block 64 having a length in the width direction smaller than that of the first block 63. . In the fireproof heat insulating material 6 of the present embodiment, only one fireproof heat insulating block 61 among the plurality of fireproof heat insulating blocks 61 arranged in parallel in the width direction is used as the second block 64, thereby the first block. It is possible to adapt to the length of the width of the panel body 1 while using 63 for the most part.

  Although not particularly illustrated, the fireproof heat insulating material 6 of the present embodiment may be a fireproof material, for example. In this case, a fireproof block is used instead of the fireproof heat insulating block 61. Furthermore, instead of the refractory heat insulating material 6 of the present embodiment, a heat insulating material may be used. In this case, a heat insulating block is used instead of the fireproof heat insulating block 61.

  In addition, as shown in FIGS. 1 and 2, the building panel of the present embodiment has a substantially U-shaped cross section in a part of the reinforcing plate housing recesses 16 among the plurality of reinforcing plate housing recesses 16 arranged in the width direction. A reinforcing member 7 having a shape is disposed.

  The reinforcing tool 7 is formed in a long shape in the longitudinal direction. The reinforcing tool 7 includes a pair of opposed pieces 71 that face each other and a connecting portion 72 that is connected to the pair of opposed pieces 71. The reinforcing tool 7 accommodates the reinforcing plate 5 therein. The reinforcing piece 7 is configured such that the facing piece 71 is in contact with or close to the reinforcing rib 15, and the connecting portion 72 is bonded and fixed to the surface of the indoor metal outer skin 11 on the core material 4 side. In the state where the reinforcing tool 7 is fixed to the surface of the indoor side metal skin 11 on the core material 4 side, the reinforcing plate 5 is bonded and fixed therein. For example, the reinforcing member 7 is formed by bending a metal plate having a thickness of about 1 mm into a substantially U shape. In addition, this reinforcement tool 7 is suitably attached | subjected according to the intensity | strength requested | required of the building panel, and may not be attached depending on the case. The reinforcing member 7 is disposed over substantially the entire length in the longitudinal direction of the building panel. However, the reinforcing member 7 is integrated over the entire length in the longitudinal direction or a plurality of reinforcing members 7 are disposed in the longitudinal direction. They may be arranged side by side and not connected to each other.

  In the panel body 1 having such a configuration, the core material 4 is filled between the outdoor side metal skin 12 and the indoor side metal skin 11. The panel body 1 of the present embodiment is composed of a body portion 20 that forms the inner and outer surfaces of the panel body 1 and connection portions 22 and 23 that are connection portions with other adjacent panel bodies 1. The connection parts 22 and 23 include a first connection part 22 provided at one end of the main body part 20 and a second connection part 23 provided at the other end. As shown in FIG. 1, the panel body 1 of the present embodiment has a first outdoor-side connecting portion 121 of the outdoor-side metal skin 12 and a first indoor-side connecting portion 111 of the indoor-side metal skin 11 facing each other. In addition, the second outdoor side connecting portion 122 of the outdoor side metal skin 12 and the second indoor side connecting portion 112 of the indoor side metal skin 11 are configured to face each other. Therefore, the 1st outdoor side connection part 121 and the 1st indoor side connection part 111 constitute the 1st connection part 22, and the 2nd outdoor side connection part 122 and the 2nd indoor side connection part 112 are The 2nd connection part 23 is comprised by this.

  In the building panel of this embodiment, the first connection portion 22 is a fitting convex portion, and the second connection portion 23 is a fitting concave portion. Then, one building panel and another building panel adjacent to the building panel are fitted to each other through the connection portions 22 and 23 to be coupled to each other. In addition, the structure of these connection parts 22 and 23 is not restricted to the thing of a fitting connection like this embodiment, In the panel for construction of this invention, it does not specifically limit. For example, the connecting portions 22 and 23 may have shapes as shown in FIGS.

  In addition, as shown in FIG. 1, the building panel according to the present embodiment has a refractory material 41 provided over substantially the entire length of the peripheral ends of the four sides separately from the reinforcing plate 5 made of the refractory material. Yes. This refractory material 41 is disposed not only inside the connection portions 22 and 23 at both ends in the width direction, but also at both ends in the longitudinal direction of the building panel. It arrange | positions so that it may contact | abut to the surface at the side of the core material 4 of the outer side metal shell 12, respectively. The building panel of the present embodiment covers the gap between the indoor side metal skin 11 and the outdoor side metal skin 12 over the entire circumference by the refractory material 41.

  As shown in FIG. 5, the panel body 1 having such a configuration is provided with an attachment member 97 for attaching the panel body 1 to the building frame.

  The attachment member 97 includes a reinforcing plate 93 fixed to the indoor side metal shell 11 and a pair of locking members 94 fixed to the reinforcing plate 93. The reinforcing plate 93 is made of a rectangular metal plate, and the fixing tool 95 is provided along the width direction of the panel body 1 at two positions in the width direction of the panel body 1 (that is, the upper part and the lower part). Attached through. As shown in FIG. 1, the reinforcing plate 93 of the present embodiment is attached to a portion corresponding to the reinforcing tool 7 having a substantially U-shaped cross section by a one-side bolt as a fixing tool 95 inserted from the indoor side. That is, the fixing tool 95 penetrates the reinforcing plate 93, the indoor side metal shell 11, the reinforcing tool 7, and the reinforcing plate member 5 in order, and sandwiches the reinforcing plate 93 and the reinforcing plate member 5, thereby fixing the reinforcing plate 93 to the reinforcing plate member 5. Secure to.

  The locking member 94 is formed by bending a band-shaped metal plate. As shown in FIG. 5, the locking member 94 has an attachment portion 941, an intermediate portion 942, and a hook portion 943, and these are continuously configured in a substantially crank shape. The locking member 94 is bolted and fixed to a reinforcing plate 93 fixed to the indoor side metal shell 11.

  In the building panel having such a configuration, a plurality of reinforcing ribs 15 which are continuous in the longitudinal direction of the panel body 1 and are arranged in the width direction of the panel body 1 are provided on the surface on the core 4 side of the indoor metal shell 11. Therefore, the rigidity of the indoor side metal shell 11 facing the indoor side can be increased. Thereby, the rigidity of panel main body 1 itself can be improved. Moreover, since the reinforcing rib 15 is provided in the indoor side metal shell 11 in the building panel of the present embodiment, the strength against pulling out the bolt or the like to the indoor side is further improved.

  In the building panel of the present embodiment, the reinforcing rib 15 formed by bending the metal plate toward the core member 4 is provided on the indoor side, and the groove portion 17 is located on the indoor side. Therefore, the bent portion for forming the reinforcing rib 15 is not exposed to the outdoor environment, and water does not stay in the groove portion 17. Thereby, compared with what provided the reinforcement rib 15 in the outdoor side, deterioration of a coating film is hard to be accelerated | stimulated and it becomes a thing which the groove part 17 vicinity does not corrode easily. Thereby, it can prevent effectively that a water stop performance falls by a hole opening in a metal plate and rainwater permeating.

  Moreover, since the reinforcement board 5 is arrange | positioned between the said reinforcement ribs 15 in addition to the some reinforcement rib 15, the rigidity of the building panel of this embodiment becomes still higher. In addition, the building panel according to the present embodiment is further improved in rigidity because the reinforcing tool 7 is provided along the longitudinal direction of the panel body 1. As a result, even a building panel that is long in the longitudinal direction is less likely to bend at the intermediate portion. Thereby, even if the long construction panel is used, the deflection in the intermediate portion can be reduced as much as possible, and as a result, the waterstop can be improved and the fire resistance and the heat insulation can be improved.

  Moreover, since the building panel of this embodiment has high rigidity, the thickness of the panel can be reduced while ensuring the strength required for the building.

  Moreover, since the core material 4 is comprised by the fireproof material which consists of the reinforcement board | plate material 5, and the fireproof heat insulating material 6, the building panel of this embodiment can ensure both fireproof performance and heat insulation performance. .

  In the building panel of this embodiment, the reinforcing plate 5 is formed in two types of width dimensions, and since there are few types of the reinforcing plate 5, mass production of the reinforcing plate 5 is easy, and inventory management is performed. Is also easy. Moreover, the reinforcing plate 5 is arranged so that the end faces do not overlap in the width direction with respect to the reinforcing plate 5 adjacent in the width direction (so-called staggered arrangement). For this reason, even if it is not integrally formed in the longitudinal direction, the strength is unlikely to decrease. Since the plurality of reinforcing plate members 5 are disposed between the reinforcing ribs 15 and positioned in the width direction, the adhesion is not easily peeled off.

  Further, in the building panel of this embodiment, a portion corresponding to the reinforcing tool 7 in the indoor metal shell 11 is an attachment member mounting portion. That is, when the panel main body 1 is supported and fixed by the mounting member 97, the highly rigid portion of the panel main body 1 can be held, so that the mounting state is stable and can be firmly fixed.

  In addition, since the mounting member 97 is fixed to the reinforcing plate 5 via the fixing member 95 inserted from the indoor side, it can be easily operated from the indoor side, and can be used for building outer wall installation work and the like. It is also suitable for office work. In addition, the opposing dimension between the reinforcing ribs 15 on which the reinforcing tools 7 are disposed is wider than the opposing dimension between the reinforcing ribs 15 on which the reinforcing tool 7 is not disposed, resulting in different width dimensions. Therefore, it can be grasped at a glance by the groove portion 17 appearing on the indoor side surface of the indoor side metal skin 11. For this reason, the operator can grasp | ascertain easily the location where the reinforcement tool 7 is arrange | positioned, and can work efficiently and reliably.

  In addition, although the fireproof heat insulating material 6 of this embodiment was comprised with the inorganic fiber material 62 (for example, rock wool), this fireproof heat insulating material 6 is normal temperature, such as a polyurethane, a styrene foam, a phenol foam, a polyisocyanurate foam. The resin heat insulating material 61 may be formed by foaming a liquid resin material. In this case, compared with the inorganic fiber material 62 such as rock wool, there is an advantage that the weight can be significantly reduced although the fire resistance is inferior. That is, since the core material 4 has the fireproof layer 5 in the building panel of this embodiment, the weight can be reduced while sufficiently securing the fireproof performance.

  In the building panel of this embodiment, as shown in FIG. 6, a metal decorative plate 8 can be installed on the indoor side metal skin 11 located on the indoor side. The decorative board 8 covers the indoor side surface of the metal skin 1. The decorative plate 8 includes a covering portion 81 that covers the plate-like portion 12 of the indoor side metal skin 11 and ear portions 82 that are connected to both ends in the longitudinal direction of the covering portion 81. The covering portion 81 is constituted by a smooth plane. The decorative plate 8 is made of a steel plate having a thickness of 0.5 mm or 0.8 mm, for example. In addition, the fixing method of the decorative board 8 is fixed to the indoor side metal shell 11 by adhesion or welding, for example.

  Since the reinforcing rib 15 is formed by bending the metal plate in the building panel of the present embodiment, a streak-like groove portion 17 is formed on the back surface of the reinforcing rib 15 in the width direction. For this reason, when the surface on the indoor side metal skin 11 side of the building panel is exposed to the indoor side as it is, the streak-like groove portion 17 becomes conspicuous when viewed from the inside. In this case, if the decorative board 8 is attached, the indoor appearance can be kept good.

  Such a building panel of this embodiment is attached and constructed as follows, for example. Hereinafter, it demonstrates based on an example which attaches the building panel of this embodiment to a wall base.

  First, as shown in FIG. 5, a vertical trunk edge 90 made of an angle material for attaching a building panel to a floor base is erected. In addition, this vertical trunk edge 90 may be C-shaped steel or H-shaped steel instead of an angle material.

  Next, as shown in FIG. 5, the building panel to which the attachment member 97 is attached is installed so that the locking member 94 of the attachment member 97 is inserted into the vertical trunk edge 90.

  A plurality of building panels attached in this way are installed in a similar construction method so as to be arranged side by side vertically and horizontally. A joint member (not shown) is mounted between the end portions of the adjacent building panels.

  Next, Embodiment 2 will be described with reference to FIG. In addition, since this embodiment is the same as Embodiment 1 for the most part, the same code | symbol is attached | subjected in the same part, description is abbreviate | omitted, and a different part is mainly demonstrated.

  In the building panel of this embodiment, as shown in FIG. 7, the fireproof heat insulating material 6 is disposed between the reinforcing ribs 15 provided on the indoor side metal skin 11, and is laminated on the fireproof heat insulating material 6. A reinforcing plate 5 is provided. The refractory heat insulating material 6 of this embodiment is made of rock wool as in the first embodiment. Further, the reinforcing plate member 5 is formed of an inorganic plate 51, and specifically, is formed of a gypsum board as in the first embodiment.

  Also with such a configuration, the rigidity of the indoor side metal shell 11 facing the indoor side can be increased, and the rigidity of the building panel can be increased.

  In addition, the fireproof heat insulating material 6 of this embodiment may be a fireproof material or a heat insulating material. Moreover, although the reinforcement board material 5 of this embodiment was a reinforcement board material which has fire resistance, the reinforcement board material which has heat insulation may be sufficient.

  Next, Embodiment 3 will be described with reference to FIG. In addition, since this embodiment is the same as Embodiment 1 for the most part, the same code | symbol is attached | subjected in the same part, description is abbreviate | omitted, and a different part is mainly demonstrated.

  The building panel of this embodiment is mainly different in the shape of the reinforcing rib 15 and the shape of the reinforcing plate member 5 from the building panel of the first embodiment, and has the same configuration. In the building panel of this embodiment, as shown in FIG. 8, the portion that protrudes toward the core material 4 is the reinforcing rib 15, and the portion that is recessed toward the core material 4 side is the reinforcing plate accommodation recess. It is 16. The protruding tip of the reinforcing rib 15 is substantially flush with the surface of the reinforcing plate member 5 on the outdoor side metal skin 12 side.

  Even with such a configuration, the same effects as those of the first embodiment can be obtained. Further, the reinforcing rib 15 of the second embodiment has a flat protruding tip and is substantially flush with the surface of the reinforcing plate 5 on the outdoor side metal skin 12 side. 15 and the inorganic plate 51 can be fixed.

  In addition, the fireproof heat insulating material 6 of this embodiment may be a fireproof material or a heat insulating material like Embodiment 1. Moreover, although the reinforcement board material 5 of this embodiment was a reinforcement board material which has fire resistance, the reinforcement board material which has heat insulation may be sufficient.

  Next, Embodiment 4 will be described with reference to FIG. In addition, since this embodiment is the same as Embodiment 1 for the most part, the same code | symbol is attached | subjected in the same part, description is abbreviate | omitted, and a different part is mainly demonstrated.

  In the building panel of the present embodiment, the core material 4 is composed of the fireproof heat insulating material 6. This refractory heat insulating material 6 has a plurality of refractory heat insulating blocks 61 and is made of rock wool. The fireproof heat insulating block 61 is disposed between the reinforcing ribs 15 and is bonded and fixed to the surface of the indoor side metal skin 11 on the core material 4 side. The building panel of this embodiment has a single-layer structure.

  Even in the building panel having such a configuration, the plurality of reinforcing ribs 15 that are continuous along the longitudinal direction of the panel main body 1 and are arranged in the width direction of the panel main body 1 are the core material 4 of the indoor side metal skin 11. Since it is provided on the side surface, the rigidity of the building panel can be increased and the strength can be improved.

  In addition, although the core material 4 of this embodiment was comprised with the fireproof heat insulating material 6, it replaced with this fireproof heat insulating material 6, and a fireproof material and a heat insulating material may be sufficient.

  Moreover, although the building panel of Embodiments 1-4 was the building panel for horizontal tension, the building panel for vertical tension may be sufficient as the building panel of this invention.

  Moreover, although the building panel of Embodiment 1-4 was attached to a building frame with the attachment member 97, in the building panel of this invention, a nail etc. is driven from the outdoor side metal shell, and a vertical column It may be fixed to a main building or the like. That is, the construction method of the building panel of the present invention is not particularly limited.

  The reinforcing ribs 15 of the first to fourth embodiments are integrally formed by roll processing, bending processing, or the like. However, in the building panel of the present invention, the reinforcing rib 15 is separately reinforced by welding, for example. The rib 15 may be attached, and this point is not always necessary.

  Moreover, although the reinforcement board | plate material 5 of Embodiment 1-3 was comprised with the gypsum board, in the building panel of this invention, it may be comprised with the calcium silicate and is not specifically limited.
