An example of embodiment of this invention is shown, (a) is the perspective view, (b) is the horizontal sectional view, (c) is the side view sectional drawing.

  Hereinafter, modes for carrying out the present invention will be described.

  As shown in FIG. 1, the fireproof panel A of the present invention is a so-called sandwich panel in which a core material 3 composed of a heat insulating material 4 and a fireproof material 5 is filled between two metal shells 1 and 2. It is formed as 1A shows a perspective view of the fireproof panel A, FIG. 1B shows a cross-sectional view taken along the line aa in FIG. 1A, and FIG. 1C shows a cross-sectional view taken along the line bb in FIG. ing.

Moreover, the thickness of the metal shells 1 and 2 can be set to 0.2 to 2.0 mm, for example. One metal skin 1 is formed as a front plate, and the other metal skin 2 is formed as a back plate. When the fireproof panel A of the present invention is used as, for example, a building exterior material, the fireproof panel A can be applied with the front panel facing the outdoor side of the building and the back panel facing the indoor side.

  The core material 3 is composed of the heat insulating material 4 and the refractory material 5 as described above, and is filled between the two metal shells 1 and 2. Although the dimension of the core material 3 can use what was formed in length 300-10000 mm, width 300-1500 mm, and thickness 20-120 mm, for example, it is not limited to these.

The heat insulating material 4 is formed by cutting and molding a fibrous inorganic material such as rock wool, glass wool or ceramic fiber into a long block shape (square bar shape), or urethane foam, styrene foam, phenol foam or polyisocyanate. A resin heat insulating material formed by foaming a liquid resin material at room temperature such as nurate foam can be used. Further, the resin heat insulating material may be formed by bonding a pre-formed molding board. The heat insulating material 4 can use what was formed in the density of 40-200 kg / m < ³ >, for example, However, It is not limited to these.

  In order not to impair the heat insulating performance of the fireproof panel A, the heat insulating material 4 is preferably provided over substantially the entire length in the longitudinal direction and the thickness direction of the core material 3.

  As the refractory material 5, for example, gypsum or calcium silicate containing calcium sulfate dihydrate as a main component can be used. Although the shape of the refractory material 5 is not particularly limited, a long rectangular plate shape or a substantially rectangular parallelepiped shape can be used. For example, a commercially available gypsum board is cut to a desired size. be able to.

  As shown in FIG. 1B, a plurality of the refractory materials 5 are provided in the width direction of the core material 3 through a predetermined interval, and specifically, at least three or more refractory materials 5 are provided. The upper limit of the number of the refractory materials 5 is preferably 20 or less, and if it is within this range, it is possible to suppress a decrease in heat insulation performance.

  And between the adjacent refractory materials 5, the heat insulating material 4 is filled. Here, it is not necessary that the heat insulating material 4 is filled between all of the adjacent refractory materials 5, and a gap may exist between a part, but in order to obtain higher heat insulating performance, It is preferable that the heat insulating material 4 is filled between all adjacent refractory materials 5. That is, it is preferable that the core material 3 is configured by alternately arranging the heat insulating materials 4 and the refractory materials 5 in the width direction.

  The arrangement pitch (interval) of the adjacent refractory materials 5 can be set to 50 to 100 mm, for example. In addition, the space | interval of each refractory material 5 may be equal intervals, and may differ. Moreover, the thickness dimension (length of the same direction as the width direction of the core material 3) of each refractory material 5 can be 5-25 mm.

  Further, the refractory material 5 can be provided over substantially the entire length of the core material 3 in the longitudinal direction. In this case, the refractory material 5 is formed in a rectangular plate shape or a substantially rectangular parallelepiped shape that is substantially equal to the length of the vertical side (longitudinal direction) of the core material 3, and extends over substantially the entire length in the longitudinal direction of the core material 3. It may be provided. Alternatively, a plurality of ones shorter than the vertical side of the core material 3 are used, and these are arranged in a line over the substantially entire length in the longitudinal direction so as to be provided over the almost entire length in the longitudinal direction of the core material 3. good. When a plurality of refractory materials 5 shorter than the longitudinal sides of the core material 3 are arranged in a row over the entire length in the longitudinal direction, the refractory materials 5 may be arranged in a row at regular intervals. good. The longitudinal direction of the core material 3 corresponds to the longitudinal direction of the fireproof panel A.

  The refractory material 5 may be provided over substantially the entire length in the thickness direction of the core material 3, and a space is provided between the refractory material 5 and the metal shells 1 and 2, and the heat insulating material 4 is interposed in the space. You may provide so that. When the refractory material 5 is provided over substantially the entire length in the thickness direction of the core material 3, if an adhesive is applied to the surface of the refractory material 5 in contact with the metal skins 1 and 2, the refractory material 5 is attached to the metal skin 1, 2 can be fixed.

  When the refractory material 5 is formed in a rectangular plate shape or a substantially rectangular parallelepiped shape, the refractory materials 5 are arranged to face each other in that the mechanical strength of the refractory panel A is improved. Is preferred.

  The four peripheral edges of the core material 3 (the outer periphery of the fireproof panel A) may be provided with the heat insulating material 4 or the fireproof material 5, but the fireproof panel A has fire resistance. It is preferable that the refractory material 5 is arranged over substantially the entire length of the peripheral ends of the four sides in that it is more excellent.

  As described above, in the fire resistant panel A of the present invention, the fire resistance of the fire resistant panel A becomes excellent by providing the plurality of fire resistant materials 5 at predetermined intervals in the width direction of the core material 3. The fire resistance performance in the width direction of the fireproof panel A is further improved.

  And since the refractory material 5 is arrange | positioned over the substantially whole length of the longitudinal direction of the core material 3, the bending strength of the refractory panel A will become more excellent, especially in the refractory panel A, one side of the refractory panel A Excellent bending strength when trying to bend from the short side to the other short side. That is, the refractory material 5 is composed of a hard material such as gypsum and calcium silicate as described above, and the refractory material 5 is provided over the entire length in the longitudinal direction of the refractory panel A. The resistance to bending of the refractory panel A is increased. Furthermore, if the refractory material 5 is provided over substantially the entire length of the core material 3 in the thickness direction, the compressive strength against the front and back surfaces of the refractory panel A will be excellent. Also in this case, since the refractory material 5 is hard, even if stress is applied in the thickness direction from the front or back surface of the refractory panel A, the refractory material 5 serves as a support between the metal shells 1 and 2, and the thickness direction It is possible to increase the resistance to compression at the same time. Therefore, it becomes easy to prevent the fireproof panel A from being damaged during transportation or construction of the fireproof panel A, and can be stably constructed on the outer wall of a building, the outer wall of a house, or the like. Further, since the metal outer skin 1 on the surface is not formed in a concavo-convex shape, the processing is not troublesome, and the surface is flat, so that the appearance is good.

  As described above, the fireproof panel A is excellent in bending strength and compressive strength. In particular, as shown in FIG. 1, the fireproof materials 5 are formed in a rectangular plate shape and arranged so as to face each other. And by providing over the substantially full length of the longitudinal direction and thickness direction of the core material 3, the bending strength and compressive strength of the fireproof panel A will improve further.

  Thus, since the bending strength of the fireproof panel A is dramatically improved, if the fireproof panel A is applied to the outer wall, it is possible to widen the trunk edge interval. Therefore, in addition to facilitating the wind pressure design of the building, the number of foundation steel frames can be reduced, the construction speed can be increased, and the material cost can be reduced and the construction cost can be reduced. It will be a thing.

  In the fireproof panel A of the present invention, the shapes of the upper and lower end portions and the left and right end portions are not particularly limited and are formed in a desired shape, and an example thereof will be described below.

  The shape of the left and right side edges of the metal shells 1 and 2 may be formed in a desired shape, and the side edge tip of one metal skin 1 formed as a surface plate as in the embodiment of FIG.

Specifically, the end of the side end portion of the metal skin 1 is bent, and the front flat portion 11, the front convex strip portion 12, and the central flat portion 10 are formed in this order from the surface side. The front flat portion 11 is formed by bending the end of the side end portion of the metal skin 1 substantially perpendicularly toward the core material 3 side, and is formed flat over the entire length of the fireproof panel A. The front ridge portion 12 is formed by bending the front flat portion 11 at the front end and bending outward, and is formed in a substantially U shape in plan view over the entire length of the fireproof panel A. The center flat portion 10 is formed by bending the front end of the front ridge portion 12 substantially perpendicularly to the back surface side, and is formed flat over the entire length of the fireproof panel A.

  In addition, the shape of both side ends of the other metal skin 2 formed as the back plate is also bent at the end of the side edge of the metal skin 2 in the same manner as the metal skin 1 so that a part of the side surface of the core material 3 is formed. You may form so that it may cover. Specifically, the end of the side end portion of the metal skin 2 is bent, and the rear ridge 13 and the rear flat portion 14 are formed in this order from the back side. The rear ridge 13 is formed by bending and bending the front end of the side of the metal skin 2 and is formed in a substantially U shape in plan view over the entire length of the fireproof panel A. The rear flat part 14 is formed by bending the front end of the rear ridge part 13 substantially perpendicularly to the surface side, and is formed flat over the entire length of the fireproof panel A.

  On the other hand, the upper and lower end portions of the metal shells 1 and 2 are also formed in a desired shape. As shown in FIG. It may be formed so as to cover a part of the upper surface. Specifically, the tip of the upper end portion of the metal shell 1 is bent, and the upper flat portion front piece 15 and the upper protruding portion 16 are formed in this order from the surface side. The upper flat portion front piece 15 is obtained by bending the upper end of the metal shell 1 substantially perpendicularly toward the core member 3 side, and is formed flat over the entire length of the fireproof panel A in the width direction. The upper ridge portion 16 is formed by bending the tip of the upper flat portion front piece 15 outwardly and is formed in a substantially U shape in plan view over the entire length of the fireproof panel A in the width direction. .

  The top end of the metal skin 2 may also be bent so as to cover a part of the top surface of the core material 3. Specifically, the upper end of the metal skin 2 is bent substantially perpendicularly toward the core material 3, and the upper flat portion rear piece 17 is formed flat over the entire length of the fireproof panel A in the width direction.

  In addition, the lower end part of the metal shells 1 and 2 is formed similarly to the upper end part, and the upper end part has a vertically inverted shape. In this case, the metal skin 1 is bent to form the lower flat portion front piece 18 and the lower convex portion 19 in this order from the surface side, and the metal outer skin 2 is bent to form the lower flat portion. A rear piece 20 is formed.

  Since the end of the fireproof panel A is formed as described above, water can be prevented from entering between the fireproof panels A and A on the outer wall constructed by arranging a plurality of fireproof panels A side by side vertically and horizontally. It becomes easy. That is, normally, the surface of the upper flat portion front piece 15 or the front flat portion 11 or the like is provided with a sealing material. Water can be stopped by a convex portion such as the strip 12, and the waterproof performance is excellent.

  Note that the upper and lower and left and right ends of the metal shells 1 and 2 are not limited to the above shapes, and are formed so as to be able to be fitted to the ends of other fireproof panels A, for example. You may do it.

  In manufacturing the fireproof panel A of the present invention, for example, it can be performed as follows. First, two metal skins 1 and 2 are prepared, and a plurality of refractory materials 5 are arranged therebetween so as to face each other with a predetermined interval in the width direction. In this case, the refractory material 5 may be fixed to the two metal shells 1 and 2 with an adhesive or the like. Subsequently, although the heat insulating material 3 is arrange | positioned between each refractory material 5, what is necessary is just to fill directly between the refractory materials 5 when the heat insulating material 3 is an inorganic type. Moreover, when the heat insulating material 3 is a resin heat insulating material, after inject | pouring a liquid resin material between each refractory material 5, by heating etc., a liquid resin material is made to foam and to harden the heat insulating material 3 Can be formed. In this way, the core material 3 composed of the heat insulating material 3 and the refractory material 5 is formed, and the refractory panel A can be manufactured by bonding and integrating with the metal shells 1 and 2. In the above manufacturing method, since the refractory material 5 is disposed between the two metal shells 1 and 2 in advance through a predetermined interval and then the heat insulating material 3 is filled in the gap, the manufacturing is simple and stable. A fireproof panel A having a shape can be manufactured.
