Description

[Technical field]

[0001] The present invention relates to a building material panel for repairing walls and roofs that is suitable for repairing existing walls (exterior walls, etc.) and existing 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] It is desirable to use such building material panels when renovating existing walls or existing roofs of building structures. As prior art in this regard, for example, reference can be made to the renovation structure for a tile roof disclosed in Patent Document 1.

[0004] Incidentally, the technology disclosed in the above-mentioned Patent Document 1 is a structure that includes multiple caps to prevent the tile bar sections from falling out, multiple sheets of insulation material placed between each of the adjacent tile bar sections, and a waterproof sheet that covers the caps and the insulation material. Since it requires a large number of parts and takes a lot of time to renovate the roof, it is difficult to say that it can be carried out efficiently, and it is inevitable that insulation defects will occur in the areas where the caps are installed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] 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.

[0015] In addition, when renovating existing walls or roofs of architectural structures, 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 of which have the same configuration as the building material panel according to the present invention, are used. 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.

[0016] 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 it can be remodeled into a flat wall or roof. 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.

[0017] 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 (foundation side or below water side) (the exterior skin material 1 and the upper joint 4 are connected in a flush state, so 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 (eaves side or above water side), 6 denotes a heat insulating member fixed and held via adhesive or the like on the back wall part of the exterior skin material 1, and 7 denotes a partition recess provided on the underside of the heat insulating member 6, which stores inside thereof protrusions (such as the upper seam and lower seam fitting parts of shingle bars and standing flat roofing) provided on the outer surface of an existing wall of a building structure or the upper surface of an existing roof. The partition recess 7 has an opening 7a at its longitudinal end.

[0018] 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 plane 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.

[0019] 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.

[0020] 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 renovated efficiently.

[0021] 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 materials such as rafters, purlins, sheathing boards and furring strips.

[0022] 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.

[0023] 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 beauty of the renovated wall or 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.

[0024] 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 .

[0025] 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.

[0026] To ensure high thermal insulation and high airtightness, a foamed plastic insulation material or a mineral fiber insulation material having a thickness of about 75 to 150 mm, more preferably about 100 mm, can be used for the heat insulating member 6. Examples of foamed plastic insulation materials that can be used include bead method polystyrene foam, extrusion method polystyrene foam, hard urethane foam, isocyanurate foam, and phenol foam.

[0027] In addition to those with a rectangular cross section, the compartment recess 7 can be other cross-sectional shapes such as a trapezoidal cross section as shown in Figure 10, which can store the fitting part of the upper and lower seams that are applied to a standing flat roof, or a semicircular cross section (not shown), and the dimensions and shape can be changed according to the protrusions provided on the existing wall and roof.

[0028] In addition, the opening 7a provided at the longitudinal end of the partition recess 7 makes it possible to make the partition recess 7 continuous from the eaves to the ridge, or from the foundation side to the eaves side, when the exterior materials 1 of the building panel are connected longitudinally. However, if the protrusions on the existing walls or roofs are not continuous from the foundation side to the eaves side, or are not continuous from the eaves to the ridge side, the opening 7a can be omitted.

[0029] 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 protrusions on the existing wall or roof can be stored inside the partition recess 7, and the upper joint 2 can be fitted into the lower joint 8a of another building material panel 8 arranged adjacently on the left side, and the lower joint 3 can be fitted into the upper joint 9a of another building material panel 9 arranged adjacently on the right side. This allows the building material panels to be joined together along the width direction of the exterior skin 1 (the eaves direction of the architectural structure).

[0030] 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.

[0031] Fig. 12 is a schematic diagram showing a situation in which an existing roof (such as a tile roof) of a building structure is renovated using a building material panel according to the present invention (upper joint 2, lower joint 3, upper joint 4, and lower joint 5 are omitted). The building material panels are joined in the order of the numbers shown in Fig. 12, that is, a so-called vertical roofing method is adopted in which priority is given to joining the longitudinal direction of the exterior material 1. Note that the building material panel placed at the eaves can be a building material panel that does not have an upper joint 4.

[0032] The heat insulating member 6 can be fixed to the exterior skin 1 by adhering it to the exterior skin 1 with an adhesive 12 as shown in Fig. 13, but to further increase the fixing strength of the heat insulating member 6 to the exterior skin 1, an anchor 13 can be provided on the back wall surface of the exterior skin 1 as shown in Fig. 14. The anchor 13 can be pierced into the heat insulating member 6 and cannot be easily pulled out of the heat insulating member 6 once pierced, thereby enabling the heat insulating member 6 to be firmly fixed to the exterior skin 1. In such a fixing structure, the adhesive 12 can also be used in combination. The anchor 13 may penetrate the heat insulating member 6.

[0033] FIG. 15 is a diagram showing a portion of a wall as an example of renovating a wall of a building structure using a building material panel according to the present invention. For existing walls, building material panels can be joined together in the same manner as for renovating a roof. When renovating 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, which makes it possible to renovate the wall while ensuring high water-stopping properties. For the building material panel arranged on the foundation side, a building material panel without an upper joint 4 can be used. [Industrial Applicability]

[0034] According to the present invention, the existing walls and roofs of a building structure can be efficiently renovated into walls and roofs with high thermal insulation and high airtightness. [Explanation of symbols]
