  The present invention relates to a building material panel in which at least a part of an internal space is filled with a filler, for example, an interior door including a front door, a fire door, a sound door, and the like, as well as a partition panel, an outer wall panel, and a shutter device. It can be used as a shutter curtain panel (for example, an overhead door or a smoke-proof wall).

  The following Patent Document 1 shows a steel door that is a building material panel. In this steel door, an interior space surrounded by four frame members on the top, bottom, left, and right sides and two surface materials on both front and back surfaces is shown. At least a portion is filled with three medium strength bones that are fillers.

In this front door, the interior is surrounded by four frame members on the top, bottom, left, and right sides and two surface materials on both front and back surfaces. At least a part of the space is filled with two honeycomb-structured core materials in which a foam material is housed inside the filler.

  In this way, the internal space surrounded by the frame material and the front and back surface materials is filled with the above-mentioned long rod-shaped members such as the medium strength bone and core material, so that the surface strength of the building material panel is increased. That is, rigidity is ensured.

JP 2011-69112 A (FIGS. 1 and 2) JP 2007-247399 A (FIGS. 1 and 2)

  By the way, in the building material panel as shown in Patent Document 1, it is troublesome to attach (fix) the three medium strength bones to the surface material at a predetermined interval. Therefore, the processing cost of the building material panel is high. It will be expensive. Moreover, in the building material panel as shown in Patent Document 2, the two core members have a honeycomb structure, and thus the material cost of the building material panel is high.

  For this reason, the device for reducing the manufacturing cost (processing cost and material cost) of a building material panel is calculated | required.

  An object of the present invention is to provide a building material panel that can reduce manufacturing costs.

  The building material panel according to the present invention is a building material panel in which at least a part of an internal space surrounded by a frame material and front and back surface materials is filled with a filler. A reinforcing material is included to reinforce the surface strength of the surface material, and the reinforcing material includes a piece core material which is a plurality of piece-shaped core materials. It is.

  In the present invention, as described above, the filler filled in at least a part of the internal space surrounded by the frame material and the front and back surface materials is reinforced to reinforce the surface strength of the front and back surface materials. The reinforcing material includes a piece core material that is a plurality of piece-shaped (in other words, small piece-shaped) core materials.

  That is, in the present invention, as described above, the reinforcing material filled in at least a part of the internal space surrounded by the frame material and the surface materials on both the front and back surfaces has a high processing cost and a high cost of material. It is not composed of a honeycomb core material, but includes a plurality of piece core materials that are easy to mass-produce and easy to mount.

  For this reason, according to the present invention, the reinforcing material constituting the filler is a building material panel as compared with the case where the reinforcing material constituting the filler is made of a core material having a high cost of processing and a honeycomb structure having a high material cost. The manufacturing cost can be reduced.

  In the present invention, the form and structure of each piece core material may be arbitrary. As an example, the thickness direction of the surface material in each piece core material in a state filled in the internal space (in other words, the building material panel Both end portions of the (thickness direction) have a shape having at least two components extending at an angle to each other in a direction orthogonal or substantially orthogonal to the thickness direction when viewed from the front. Can be mentioned.

  The piece core material is fixed to at least one surface material of the two surface materials forming both the front and back surfaces of the building material panel. In order to fix the piece core material to the surface material, The surface material forming one of the surfaces is placed flat, and the work of placing and fixing the piece core material on the flatly placed surface material is performed.

  When the piece core material has the shape of the above-described example, the piece core material temporarily placed on the flat surface material does not fall down, so the piece core material is placed and fixed on the flat surface material. Work can be easily performed.

  Further, since the piece core material has the shape of the above-described example, when an external force in the thickness direction of the surface material is applied to the surface material, the surface strength against the external force of the surface material is sufficiently ensured. Become so.

  Here, “the opposite ends of the surface material in the thickness direction of each piece core material in the state of being filled in the internal space are orthogonal or substantially orthogonal to the thickness direction as viewed from the thickness direction. The shape having at least two components extending at an angle to each other specifically refers to, for example, a radial shape (for example, a cross shape or a substantially cross shape, an X shape or a substantially X shape) in the front view. Shape, etc.), U-shaped or substantially U-shaped, V-shaped or substantially V-shaped, C-shaped or substantially C-shaped, annular (in other words, ring-shaped) (for example, annular or substantially annular, triangular A ring or a substantially triangular ring, a quadrangular ring or a substantially square ring, a pentagonal ring or a substantially pentagonal ring, etc., a circular or a substantially circular shape, a polygonal shape (for example, a triangular or a substantially triangular shape, a quadrangular or a substantially quadrangular shape, a pentagonal shape) Or a substantially pentagonal shape).

  In the present invention, the above-described “both ends in the thickness direction of the surface material in each piece core material in a state where the inner space is filled are orthogonal or substantially perpendicular to the thickness direction as viewed from the thickness direction. The piece core material having “a shape having at least two components extending at an angle to each other in an orthogonal direction” may or may not be formed of a plate material.

  In the former case, the piece core material may be formed, for example, by bending a plate material, or may be formed by combining a plurality of plate materials. In the latter case, the piece core material may be, for example, a pultruded molded product, an extruded molded product, an injection molded product, or a metallic product, which may be a cast product or a forged product.

  As described above, both end portions in the thickness direction of the surface material in each piece core material in a state where the inner space is filled are orthogonal or substantially orthogonal to the thickness direction in a front view as viewed from the thickness direction. In the case of having a shape having at least two components extending at an angle to each other in the direction, and the piece core material is formed of a plate material as described above, the front view of the piece core material For example, as described above, the shape may be a cross shape or a substantially cross shape, may be a U shape or a substantially U shape, and is a C shape or a substantially C shape. It may be V-shaped or substantially V-shaped.

  In addition, when the piece core material is formed of a plate material, and the shape of the piece core material in the front view is a cross shape or a substantially cross shape as described above, the piece core material is It may or may not be formed by a combination of a plurality of piece members.

  In the former case, the piece core material is, for example, a plate-shaped first portion provided with a cut portion cut from a portion that is one end portion of both end portions in the thickness direction of the surface material in the piece core material. It is formed by a combination of a piece member and a plate-like second piece member provided with a cut portion cut from the other end portion of the both end portions, and the first piece member The first piece member and the second piece member may be coupled orthogonally or substantially orthogonally to each other by engaging the notch portion with the notch portion of the second piece member.

  In this example, the first piece member and the second piece member can have the same shape and structure, i.e., the second piece member can be an upside down version of the first piece member. Therefore, mass production of piece core materials becomes easy, and the manufacturing cost of the panel for building materials can be reduced accordingly.

  In addition, when the piece core material is formed of a plate material, the shape of the piece core material in the front view is, as described above, a U shape or a substantially U shape, or a C shape or a substantially C shape, Or when it becomes V shape or substantially V shape etc., each piece core material in the standing state of the panel for building materials is filled in the internal space in the posture opened upward in the front view. You may or may not be.

  In the event of a fire, the standing building panel is heated to heat up the internal space surrounded by the surface material, but each piece core in the standing state When the material is filled in the internal space in a posture opened downward in the front view, hot air is filled in each piece core material, and the building material panel is likely to be thermally deformed.

  For this reason, it is preferable that each piece core material in the standing state of the building material panel is filled in the internal space in an attitude of opening upward in the front view.

  Further, as described above, both end portions in the thickness direction of the surface material in each piece core material in the state where the internal space is filled are orthogonal or substantially perpendicular to the thickness direction in a front view as viewed from the thickness direction. In the case of having a shape having at least two components extending at an angle to each other in an orthogonal direction, and the piece core material is formed of a plate material, the thickness direction of the surface material is the internal When the width direction of each piece core material is filled in the space, and the width dimension of each piece core material is the same or substantially the same as the interval between the front and back surface materials, the inside A through hole may or may not be formed in a portion that closes or substantially closes between the front and back surface materials of each piece core material in a state where the space is filled.

  As described above, when a fire occurs, the building material panel in a standing state is heated, so that hot air rises in the internal space surrounded by the surface material. Of each piece core material in the state where the internal space is filled, the building material panel is likely to be thermally deformed by being blocked by a portion that closes or closes between the front and back surface materials.

  When the through-hole is formed in the above portion, the raised hot air passes through this through-hole, thereby preventing the raised hot air from filling the piece core material. For this reason, it is preferable that a through-hole is formed in a portion that closes or substantially closes between the front and back surface materials of each piece core material in a state of being filled in the internal space.

  In the present invention, as described above, both end portions in the thickness direction of the surface material in each piece core material in the state where the internal space is filled are in the thickness direction in a front view as viewed from the thickness direction. If the piece core material has a shape having at least two components extending at an angle to each other in a direction orthogonal or substantially orthogonal to the shape, and the piece core material is not formed of a plate material, The shape is, for example, a short cylindrical shape (for example, a cylindrical shape or a substantially cylindrical shape, a triangular cylindrical shape or a substantially triangular cylindrical shape, a square cylindrical shape or a substantially rectangular cylindrical shape, a pentagonal cylindrical shape or a substantially pentagonal cylindrical shape, etc.) Short columnar shapes (for example, a columnar shape or a substantially cylindrical shape, a prismatic shape (for example, a triangular columnar shape or a substantially triangular columnar shape, a quadrangular columnar shape or a substantially quadrangular columnar shape, a pentagonal columnar shape, a substantially pentagonal columnar shape, or the like)).

  In the present invention described above, at least a part of the internal space excluding the portion filled with the reinforcing material has a soundproofing and / or fireproofing wool material, soundproofing and / or fireproofing. A non-combustible foam material obtained by foaming an inorganic material having properties may or may not be filled.

  In the case of the former, when the building material panel requires soundproofing and / or fireproofing, in other words, the building material panel is placed at the location of the structure where soundproofing and / or fireproofing is required. It will be the case.

  As in the former case, by filling the wool material or the non-combustible foam material, the soundproof property (sound insulation property), fireproof property, heat insulation property and the like of the manufactured building material panel are ensured.

  The “wool material” includes glass wool, rock wool, and the like. Further, the above-mentioned “inorganic material” does not mean that no organic material is included, and some organic material may be included.

  The “structure” described above includes a building, and also includes an underground mall, an automobile, a train car, a ship, and the like.

  In the present invention described above, when the piece core material is the first reinforcing material, the internal space is also filled with the second reinforcing material, and the second reinforcing material is longer in length than the piece core material. It may be a long and long rod-shaped member.

  Here, the form and structure of the long rod-shaped member may be arbitrary, for example, a rod-shaped channel material formed by bending a plate material, a hollow rod-shaped member, a honeycomb-shaped rod-shaped member, etc. Good.

  When the piece core material is the first filler, the wool material is the second filler, and the rod-shaped member is the third filler.

  In the present invention described above, at least one end portion of both end portions in the thickness direction of the surface material of each piece core material in a state in which the internal space is filled is fixed to the surface material facing this end portion. What should I do?

  Here, the fixing may be, for example, bonding (for example, adhesive or double-sided tape), welding (for example, plug welding), fitting, engagement, or the like. Good.

  In the present invention, in the internal space surrounded by the frame material and the front and back surface materials, a portion (in other words, a portion) filled with a plurality of piece core materials is the aforementioned wool material in the internal space. And / or any location except where the second reinforcing material is filled.

  For example, the plurality of piece core materials correspond to the central portion in the width direction of the surface material or the substantially central portion or the vicinity thereof in the inner space, and correspond to the central portion in the length direction of the surface material, the substantially central portion or the vicinity thereof. The space to be filled may or may not be filled.

  In other words, the plurality of piece core materials may or may not be filled in the space corresponding to the center of gravity of the building material panel or the vicinity thereof in the internal space.

  According to the former case, as compared with the latter case, it is possible to prevent the building material panel from being largely thermally deformed when a fire occurs.

  The present invention described above can be applied to any building material panel, an example of which is a front door, and another example is an indoor door including a soundproof door, a fire door, etc. The invention can also be applied to partition panels, outer wall panels, shutter curtain panels for shutter devices (for example, overhead doors, smoke-proof hanging walls, etc.), and the like. These may be installed in a building, or may be installed in a structure other than a building such as an underground mall, an automobile, a train car, or a ship as described above.

  According to the present invention, it is possible to reduce the manufacturing cost of a building material panel.
