Description

[Technical field]

[0001] The present invention relates to a building material panel suitable for constructing the exterior walls and roofs of building structures. [Background technology]

[0002] Building material panels, which have a metal sheet as the outer skin and a thermal insulation material on the back side, have the advantages of being lightweight, strong, and highly insulating, and are widely used as exterior wall and roofing materials for architectural structures such as factories and warehouses, ordinary homes and apartment buildings, commercial facilities such as stores, and livestock barns.

[0003] However, because such building material panels have a high insulating efficiency, moisture contained in the base materials of walls and roofs, or moisture in a room or attic, tends to accumulate inside the insulating members, and there is concern that condensation caused by that moisture will cause the base materials and other components to rot.

[0004] In order to prevent the decay of structural components due to condensation, attempts have been made in the past to prevent moisture from accumulating by taking measures such as providing separate ventilation paths inside the walls or under the roof. However, this not only makes the structure of the building complex, but also increases the thickness of the walls and roof, resulting in unavoidable problems such as a reduction in living space and an unnecessarily high height of the building structure itself, and an improvement in this area was needed.

[0005] As a technology for efficiently discharging moisture trapped between the base material and the insulating member, reference can be made to the technology disclosed in Patent Document 1, which relates to a ventilated insulating material and insulating panel with insulating, deterioration prevention, and drainage functions, and an insulated roof using these. However, the technology disclosed in Patent Document 1 is a structure in which insulating material blocks are combined and roofing material is placed on top of them, which requires a great deal of work and cannot be said to be easy to install.

[0006] [Patent Document 1] Patent No. 4181608 Summary of the Invention [Problem to be solved by the invention]

[0007] To provide a building material panel that can efficiently expel moisture contained in a base material and moisture inside a room, attic, etc. to the outside of a building structure while ensuring excellent workability. [Means for solving the problem]

[0008] The present invention is a building material panel that comprises a metal exterior skin having an upper joint at one widthwise end and a lower joint at the other widthwise end, and an insulating member installed on the back side of the exterior skin, in which the upper joint provided at one widthwise end of the exterior skin is fitted into the lower joint of another building material panel that is adjacent to the exterior skin on the right or left side in the width direction, while the lower joint provided at the other widthwise end of the exterior skin is fitted into the upper joint of another building material panel that is adjacent to the exterior skin on the left or right side in the width direction, thereby connecting the building material panels to each other to construct the walls or roof of an architectural structure, and is characterized in that the insulating member is fixed and held on the back wall surface of the exterior skin, and has at least one partition recess that cooperates with the back wall surface of the exterior skin to form an air layer (internal passage) along the longitudinal direction of the exterior skin.

[0009] In the building material panel having the above configuration, 1) The exterior skin material has, at one end in the longitudinal direction, an upper joint that can be connected to a lower joint of another building material panel that is adjacently arranged on the foundation side or below water side of the building structure, and has, at the other end in the longitudinal direction, a lower joint that can be connected to an upper joint of another building material panel that is adjacently arranged on the eaves side or above water side of the building structure; 2) the air layer has an opening at an end in the longitudinal direction of the air layer; 3) The heat insulating member has a horizontal recess provided in a direction intersecting with the partition recess, and the end portion of the heat insulating member is connected to each of the adjacent partition recesses. 4) The heat insulating member is made of a foamed plastic heat insulating material. 5) The outer skin material has a flat outer surface, and 6) As a specific means for solving the problem, it is preferable that the outer skin material has at least one anchor provided on its back wall portion, which penetrates the insulation member to prevent the insulation member from falling off from the outer skin material.

[0010] In the present invention, "the upper joint of the skin is fitted into the lower joint of another building material panel adjacently arranged on the right or left side in the width direction of the skin, while the lower joint provided at the other end of the skin in the width direction is fitted into the upper joint of another building material panel adjacently arranged on the left or right side in the width direction of the skin" refers to the case where the upper joint provided at one end of the skin in the width direction of the building material panel according to the present invention is fitted into the lower joint of another building material panel adjacently arranged on the right side in the width direction of the skin. This means that when a lower joint provided at the other end in the width direction of the skin material of a building material panel according to the present invention fits into an upper joint of another building material panel arranged adjacently on the left side in the width direction of the skin material, and an upper joint provided at one end in the width direction of the skin material of a building material panel according to the present invention fits into an upper joint of another building material panel arranged adjacently on the left side in the width direction of the skin material, the lower joint provided at the other end in the width direction of the skin material of a building material panel according to the present invention fits into an upper joint of another building material panel arranged adjacently on the right side in the width direction of the skin material, and does not include other combinations.

[0011] In addition, in the present invention, "the exterior skin material has, at one longitudinal end, an upper joint that can be connected to a lower joint of another building material panel that is adjacently arranged on the foundation side or belowwater side of the architectural structure, and has, at the other longitudinal end, a lower joint that can be connected to a lower joint of another building material panel that is adjacently arranged on the eaves side or abovewater side of the architectural structure" means that when one longitudinal end of the exterior skin material of a building material panel according to the present invention has an upper joint that can be connected to a lower joint of another building material panel that is adjacently arranged on the foundation side of an architectural structure, the other longitudinal end has a lower joint that can be connected to a lower joint of another building material panel that is adjacently arranged on the eaves side of the architectural structure, and when one longitudinal end of the exterior skin material of a building material panel according to the present invention has an upper joint that can be connected to a lower joint of another building material panel that is adjacently arranged on the belowwater side, the other longitudinal end has a lower joint that can be connected to a lower joint of another building material panel that is adjacently arranged on the abovewater side, and does not include other combinations. Effect of the Invention

[0012] According to the present invention, the insulating member is made of a highly moisture-permeable insulating material, and moisture that passes through the insulating member can be discharged to the outside of the building structure through the air layer, thereby preventing decay of the wall and roof base materials due to condensation caused by moisture.

[0013] Furthermore, because the heat insulating member is fixedly held on the rear wall surface of the exterior material, the building material panels are easy to handle during construction, allowing walls and roofs to be constructed efficiently. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The present invention will now be described in more detail with reference to the drawings. Fig. 1 is an external perspective view showing a schematic representation of an embodiment of a building material panel according to the present invention, and Fig. 2 is an external perspective view showing an exploded state of the building material panel shown in Fig. 1. Also, Fig. 3 is a front view of the building material panel shown in Fig. 1, Fig. 4 is a plan view of the building material panel shown in Fig. 3, Fig. 5 is a bottom view of the building material panel shown in Fig. 3, Fig. 6 is a rear view of the building material panel shown in Fig. 3, Fig. 7 is a left side view of the building material panel shown in Fig. 3, Fig. 8 is a right side view of the building material panel shown in Fig. 3, and Fig. 9 is a schematic view showing a state in which the building material panel according to the present invention is joined to another building material panel arranged adjacent to it on the left side and to another building material panel arranged adjacent to it on the right side.

[0016] In constructing the roof or walls of a building structure, it is assumed that multiple building material panels having the same configuration as the building material panel according to the present invention will be used, and the other building material panels arranged adjacent to the right or left side of the exterior skin in the width direction, the other building material panels arranged adjacent to the left or right side of the exterior skin in the width direction, the other building material panels arranged adjacent to the foundation side or below water side, and the other building material panels arranged adjacent to the eaves side or above water side, all have the same configuration as the building material panels according to the present invention. Note that the width and length of the building material panels can be changed as desired, and are not limited to building material panels with the aspect ratios shown in the figures.

[0017] Reference numeral 1 in Figures 1 to 9 denotes a metal skin material that forms the basic framework of a building panel according to the present invention. The skin material 1 is surrounded by a pair of short sides and a pair of long sides that sandwich the pair of short sides from both sides, and has a rectangular outline in a plan view, and its upper surface is flat so that flat walls and roofs can be constructed. The direction along the short sides is referred to as the width direction of the skin material 1, and the direction along the long sides is referred to as the longitudinal direction of the skin material 1.

[0018] 1 to 9, reference numeral 2 denotes an upper joint integrally connected to one end of the exterior skin material 1 in the width direction, 3 denotes a lower joint integrally connected to the other end of the exterior skin material 1 in the width direction, 4 denotes an upper joint integrally provided at one end of the exterior skin material 1 in the longitudinal direction (the exterior skin material 1 and the upper joint 4 are connected in a flush state, and therefore the boundary between them is shown by a dotted line for convenience), 5 denotes a lower joint integrally provided at the other end of the exterior skin material 1 in the longitudinal direction, 6 denotes a heat insulating member fixed and held via an adhesive or the like on the back wall portion of the exterior skin material 1, and 7 denotes a partition recess provided in the heat insulating member 6 and forming an air layer along the longitudinal direction of the exterior skin material 1 in cooperation with the back wall surface of the exterior skin material 1. The air layer formed by the partition recess 7 has the function of discharging moisture that has passed through the heat insulating member 6 from the ridge side of the roof or the eaves side of the wall to the outside of the building structure.

[0019] In the example shown, the upper joint 2 is provided on the left side of the skin material 1, which is one end in the width direction, when the planar shape of the skin material 1 shown in Fig. 4 is used as a reference, and the lower joint 3 is provided on the right side of the skin material 1, which is the other end in the width direction, but the upper joint 2 can also be provided on the right side in the width direction of the skin material 1, and the lower joint 3 can also be provided on the left side in the width direction of the skin material 1, and this is not limited. In the present invention, an example will be described in which the upper joint 2 is provided on the left side in the width direction of the skin material 1, and the lower joint 3 is provided on the right side in the width direction of the skin material 1.

[0020] The upper joint 2 is connected flush with the exterior skin material 1 and, as shown in Figure 9, is composed of a joint body 2a that covers the lower joint 8a of another building material panel 8 that is arranged adjacently on the left side, a hook-shaped piece 2b that is connected to the tip of the joint body 2a and wraps around to the back side of the joint body 2a, and a curling portion 2c that is connected to the tip of the hook-shaped piece 2b and can fit into the lower joint 8a of another building material panel 8 that is arranged adjacently on the left side due to springback of at least one of the joint body 2a and the hook-shaped piece 2b.

[0021] When the upper joint 2 is provided with a curling portion 2c, the building material panels can be joined together with a single touch, making construction easy and enabling roofs and walls to be constructed efficiently.

[0022] The lower joint 3 is also composed of a groove portion 3a that allows the curling portion 9b of the upper joint 9a of another building material panel 9 arranged adjacently on the right side to enter, an overhang portion 3b that protrudes into the groove portion 3a and fits into the curling portion 9b of another building material panel 9 arranged adjacently on the right side, a land portion 3c that is connected to the overhang portion 3b and has a top surface that fits along the back side of the upper joint 9a of the building material panel 9 arranged adjacently on the right side, and a recess 3d that is provided adjacent to the land portion 3c and has a drill screw driven into the bottom wall to fix the building material panel to the base material such as a purlin, sheathing board, or pillar.

[0023] The recess 3d can be composed of a side wall 3d1 connected to the land portion 3c, a bottom wall 3d2 connected to the lower end of the side wall 3d1, and a vertical wall portion 3d3 connected to the bottom wall 3d2 in an upright position and forming the end face of the lower joint 3, and the groove portion 3a of the lower joint 3 can be composed of an inclined side wall connected to the widthwise end of the outer skin material 1, and an inclined side wall having one end connected to the lower end of the inclined side wall and the other end connected to the lower end of the overhang portion 3b at an opposite slope to the inclined side wall.

[0024] The recess 3d serves to prevent the drill screw from appearing on the outer surface of the building material panel when it is joined to another building material panel 9 arranged adjacently on the right side, thereby maintaining the aesthetic appearance of the constructed wall and roof. The recess 3d also functions as an internal gutter, and even if rainwater or the like infiltrates through the joint surface between the upper joint 9a and the lower joint 3 of another building material panel 9 arranged adjacently on the right side due to osmotic pressure, the infiltrating rainwater or the like can be efficiently discharged through the recess 3d.

[0025] The upper joint 2 and the lower joint 3 have extended ends 2 ′, 3 ′ extending to an upper joint 4 and a lower joint 5 provided in the longitudinal direction of the outer skin material 1 .

[0026] The outer skin material 1, including the upper joint 2, the lower joint 3, the upper joint 4, and the lower joint 5, is formed by subjecting a single plate material to forming processing such as roll forming, using a zinc-plated steel plate, an aluminum-zinc alloy-plated plate, a stainless steel plate, an aluminum plate, a copper plate, or painted or coated steel plates having a thickness of about 0.2 to 1.0 mm, more preferably about 0.5 mm.

[0027] In order to ensure high insulation and high airtightness while allowing easy passage of moisture, the heat insulating member 6 can be a foamed plastic board-shaped heat insulating member or a mineral fiber board-shaped heat insulating member having a thickness of about 75 to 150 mm, more preferably about 100 mm. Examples of foamed plastic heat insulating materials that can be used include bead method polystyrene foam, extrusion method polystyrene foam, rigid urethane foam, isocyanurate foam, and phenol foam.

[0028] The compartment recesses 7 may have a rectangular cross section, or may have a triangular cross section as shown in Fig. 10, or a semicircular cross section (not shown), or other cross-sectional shapes, and any cross-sectional shape can efficiently discharge moisture to the outside of the building structure. The number of compartment recesses 7 is determined within a range that does not reduce the fixing strength between the exterior skin material 1 and the board-shaped insulation member.

[0029] In addition, an opening 7a can be formed at the longitudinal end of the partition recess 7, so that when the building material panels are joined together in the longitudinal direction of the exterior skin material 1, an air layer can be made continuous from the eaves to the ridge, or from the foundation side to the eaves ceiling, allowing moisture that has passed through the insulation material 6 to be efficiently discharged to the outside of the building structure.

[0030] To join building material panels according to the present invention along the width direction of the exterior skin 1, as shown in Figure 9 above, the upper joint 2 is fitted into the lower joint 8a of another building material panel 8 arranged adjacently on the left side, and the lower joint 3 is fitted into the upper joint 9a provided on another building material panel 9 arranged adjacently on the right side, thereby making it possible to join the building material panels to each other along the width direction of the exterior skin 1 (the eaves direction of the architectural structure).

[0031] To join building material panels according to the present invention along the longitudinal direction of the exterior skin 1, as shown in Fig. 11, the upper joint 4 is overlapped and linked over the lower joint 10a provided on another building material panel 10 adjacently arranged on the downwater side of the architectural structure, and the lower joint 5 provided at the other longitudinal end is overlapped and linked under the upper joint 11a of another building material panel 11 adjacently arranged on the abovewater side, thereby making it possible to join the building material panels from the foundation side toward the eaves side or the eaves or ridge. When the upper joint 4 is linked to the lower joint 10a, and when the lower joint 5 is linked to the upper joint 11a, a joint packing and a waterproof packing P are placed between them.

[0032] Fig. 12 is a schematic diagram showing how the roof of a building structure is constructed using building panels according to the present invention. The building panels are joined together in the order of the numbers shown in Fig. 12, i.e., the so-called vertical roofing method is adopted, in which the longitudinal joining of the building panels is prioritized. Note that the building panels placed at the eaves of the roof do not have upper joints 4.

[0033] When constructing a roof using a building material panel according to the present invention, it is preferable to use roofing L with low moisture permeability resistance as the roofing covering the surface of the sheathing board N, and when constructing a wall, it is preferable to use a waterproof sheet L1 (see Figure 16) with low moisture permeability resistance as the waterproof sheet covering the base material S.

[0034] 13 is an external perspective view of another embodiment of a building panel according to the present invention, showing a heat insulating member 6. The heat insulating member 6 can be provided with a lateral recess 12 whose end portion communicates with an adjacent partition recess 7 in a direction intersecting (or may be perpendicular to) the partition recess 7, and the lateral recess 12 can increase the efficiency of moisture discharge.

[0035] The horizontal recesses 12 are provided within a range that ensures sufficient fixing strength of the heat insulating member 6 to the exterior skin material 1, and there are no limitations on the size or number of the horizontal recesses 12 to be provided.

[0036] The heat insulating member 6 can be fixed to the exterior skin 1 by adhering it to the exterior skin 1 with an adhesive 13 as shown in Fig. 14, but to further increase the fixing strength of the heat insulating member 6 to the exterior skin 1, an anchor 14 can be provided on the back wall surface of the exterior skin 1 as shown in Fig. 15, which can be pierced into the heat insulating member 6 and cannot be easily pulled out once pierced, thereby enabling the heat insulating member 6 to be firmly fixed to the exterior skin 1. The anchor 14 may also penetrate the heat insulating member 6.

[0037] FIG. 16 is a diagram showing a part of an example of a wall of a building structure constructed using building material panels according to the present invention. Building material panels can be joined together for the wall in the same manner as for constructing a roof. When constructing a wall, it is preferable to arrange the upper joint 4 so that it faces the foundation side of the building structure and the lower joint 5 so that it faces the eaves side, thereby ensuring high water-stopping properties while efficiently discharging moisture contained in the base material and moisture inside the room and attic to the outside of the building structure. Building material panels that do not have upper joint 4 are used for the building material panels that are arranged on the foundation side. [Industrial Applicability]

[0038] According to the present invention, it is possible to efficiently discharge moisture contained in base materials and the like to the outside of a building while ensuring excellent workability. [Explanation of symbols]
