Description

The present invention relates to a building material panel for renovating walls and roofs that is suitable for renovating existing walls (exterior walls, etc.) and existing roofs of building structures.

Construction panels, which have a metal sheet as the outer skin and insulating 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, residential and apartment buildings, commercial facilities such as stores, and livestock barns.

It is desirable to use such building material panels when renovating existing walls and roofs of building structures, and reference can be made, for example, to the renovation structure for a tile roof disclosed in Patent Document 1 as a prior art in this regard.

The technology disclosed in the above-mentioned Patent Document 1 is a structure that includes multiple caps that prevent the tile bar sections from falling out, multiple sheets of insulation material that are placed between each adjacent tile bar section, and a waterproof sheet that covers the caps and insulation material. Since it requires a large number of parts and is time-consuming to repair the roof, it is difficult to say that the construction can be carried out efficiently, and insulation defects are unavoidable in the areas where the caps are installed.

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 other building material panels arranged adjacent to the right or left side of the exterior skin in the width direction, other building material panels arranged adjacent to the left or right side of the exterior skin in the width direction, other building material panels arranged adjacent to the foundation side or below water side, and other building material panels arranged adjacent to the eaves side or above water side will also be of the same configuration as the building material panel according to the present invention. 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.

Reference numeral 1 in Figures 1 to 9 denotes a metal exterior material that forms the basic framework of a building panel according to the present invention. The exterior 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, with its top surface being 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 exterior material 1, and the direction along the long sides is referred to as the longitudinal direction of the exterior material 1.

In addition, in Figs. 1 to 9, the reference numeral 2 denotes an upper joint integrally connected to one end of the exterior skin 1 in the width direction, 3 denotes a lower joint integrally connected to the other end of the exterior skin 1 in the width direction, 4 denotes an upper joint integrally provided at one end of the exterior skin 1 in the longitudinal direction (foundation side or below water side) (the exterior skin 1 and 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 1 in the longitudinal direction (eaves side or above water side), 6 denotes a heat insulating member fixed and held by adhesive or the like on the back wall of the exterior skin 1, and 7 denotes a partition recess provided on the underside of the heat insulating member 6, which stores inside it protrusions (such as the upper and lower seams of shingle bars and vertical flat roofing) provided on the outer surface of an existing wall or the upper surface of an existing roof of a building structure. The partition recess 7 has an opening 7a at its longitudinal end.

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 Figure 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. However, 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 this 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.

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

When the upper joint 2 is equipped with a curling section 2c, building material panels can be joined together with a single touch, making construction easy and allowing roofs and walls to be renovated efficiently.

The lower joint 3 is also composed of a groove 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 overhanging portion 3b that protrudes into the groove 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 overhanging 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 recessed portion 3d that is provided adjacent to the land portion 3c and that drives a drill screw into the bottom wall to fix the building material panel to the base material such as rafters, purlins, sheathing boards, and furring strips.

The recess 3d can be made up 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. The groove portion 3a of the lower joint 3 can be made up of an inclined side wall connected to the end in the width direction 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 inverse gradient to the inclined side wall.

The recess 3d prevents the drill screw from appearing on the outer surface of the building material panel when it is joined to another building material panel 9 located adjacent to the right side, and maintains 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 located adjacent to the right side due to osmotic pressure, the infiltrating rainwater or the like can be efficiently discharged through the recess 3d.

In addition, the upper joint 2 and the lower joint 3 have extended ends 2', 3' that extend to the upper joint 4 and the lower joint 5, which are provided in the longitudinal direction of the outer skin material 1.

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

In order to ensure high insulation and airtightness, the insulating member 6 can be made of a foamed plastic insulation material or a mineral fiber insulation material with a thickness of about 75 to 150 mm, more preferably about 100 mm. Examples of foamed plastic insulation materials that can be used include bead-method polystyrene foam, extruded polystyrene foam, rigid urethane foam, isocyanurate foam, and phenol foam.

The compartment recess 7 can have a rectangular cross section, or it can have a trapezoidal cross section as shown in FIG. 10, which can accommodate the fitting of the upper and lower seams that are used in vertical flat roofs, or a semicircular cross section (not shown), and other cross-sectional shapes can be applied, and the dimensions and shape can be changed according to the protrusions provided on the existing walls and roof.

The opening 7a at the longitudinal end of the partition recess 7 allows the partition recess 7 to be 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 joined in the longitudinal direction. However, if the protrusions on the existing wall or roof 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.

To join building panels according to the present invention together along the width direction of the exterior skin 1, as shown in Figure 9 above, the protrusions on the existing wall or roof are stored inside the partition recess 7, and the upper joint 2 is fitted into the lower joint 8a of another building panel 8 adjacent to the left side, and the lower joint 3 is fitted into the upper joint 9a of another building panel 9 adjacent to the right side. This allows the building panels to be joined together along the width direction of the exterior skin 1 (the eaves direction of the building structure).

To join building panels according to the present invention along the longitudinal direction of the exterior material 1, as shown in FIG. 11, the upper joint 4 is overlapped and linked on the lower joint 10a of another building panel 10 adjacent to the building structure on the downstream side, and the lower joint 5 at the other longitudinal end is overlapped and linked under the upper joint 11a of another building panel 11 adjacent to the building structure on the abovewater side, thereby connecting the building panels from the foundation side to the eaves side or from the eaves to the ridge. When the upper joint 4 is connected to the lower joint 10a, and when the lower joint 5 is connected to the upper joint 11a, a joint packing and a watertight packing P are placed between them.

Figure 12 is a schematic diagram showing the situation in which an existing roof (such as a tiled 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 Figure 12, that is, a so-called vertical roofing method is used, in which priority is given to joining the longitudinal direction of the exterior material 1. Note that the building material panels placed at the eaves can be building material panels that do not have upper joint 4.

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

Figure 15 shows an example of a portion of a wall of an architectural structure that is renovated 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 when 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 architectural 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. The building material panel that is placed on the foundation side can be a building material panel that does not have an upper joint 4.

The present invention allows existing walls and roofs of building structures to be efficiently renovated into highly insulated and airtight walls and roofs.
