Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
1 is a plan view showing a metal roofing material according to Embodiment 1 of the present invention, FIG. 2 is a sectional view taken along line II-II in FIG. 1, and FIG. 3 is taken along line III-III in FIG. FIG. 4 is a cross-sectional view, and FIG. 4 is a perspective view showing the reinforcing member 5 of FIG. As shown in FIG. 1, the metal roofing material 1 is a member having a substantially rectangular shape in a plan view having a short direction 1S and a longitudinal direction 1L (width direction), and is disposed on a roof base in a roof such as a house. Is. As will be described later with reference to the drawings, the metal roofing material 1 is placed on the roof base so that the longitudinal direction 1L is along the direction 6 parallel to the eaves of the roof and the short direction 1S is along the eaves direction 7 of the roof. Is arranged (see FIG. 5). As shown in FIGS. 1 to 3, the metal roof material 1 has a front base material 2, a back base material 3, a core material 4, and a plurality of reinforcing members 5.

  The front substrate 2 is a metal member made of a metal plate, and is a member that appears on the outer surface of the roof when the metal roofing material 1 is placed on the roof base. The shape of the surface base material 2 of this Embodiment is made into the box shape which has a top plate and a surrounding wall. However, the front substrate 2 may have another shape such as a flat plate shape.

  The metal plate that is the material of the front substrate 2 includes a hot-dip Zn-based plated steel plate, hot-dip Al-plated steel plate, hot-dip Zn-plated stainless steel plate, hot-dip Al-plated stainless steel plate, stainless steel plate, Al plate, Ti plate, and paint-melted Zn-based plate. A plated steel plate, a coated hot-dip Al-plated steel plate, a coated hot-dip Zn-based plated stainless steel plate, a painted hot-Al plated stainless steel plate, a painted stainless steel plate, a painted Al plate, or a coated Ti plate can be used. When making the front substrate 2 into a box shape, it is preferable to draw the steel plate to form the front substrate 2. This is because work hardening occurs on the peripheral wall by drawing the steel sheet, and the wind pressure resistance of the metal roofing material 1 can be improved.

  The front base material 2 is provided with a plurality of fastening holes 20 spaced from each other in the longitudinal direction 1L of the metal roofing material 1. The tight hole 20 indicates a driving position of the tight member 8 (see FIG. 6) into the metal roofing material 1. The binding member 8 is made of, for example, a screw or a nail, and is used for binding the metal roof material 1 to the roof base. In the present embodiment, the tightening hole 20 is described as being provided in the front base material 2. However, for example, a printed symbol or a non-opening mark indicating the driving position of the tightening member such as unevenness is provided. It may be provided only on the surface of the front substrate 2.

  The back substrate 3 is a member disposed on the back side of the front substrate 2. As the back substrate 3, a lightweight material such as aluminum foil, aluminum vapor-deposited paper, aluminum hydroxide paper, calcium carbonate paper, resin film or glass fiber paper can be used. By using these lightweight materials for the back substrate 3, it is possible to avoid an increase in the weight of the metal roofing material 1.

  The core material 4 is made of a foamed resin filled between the front base material 2 and the back base material 3. By filling the foamed resin between the front base material 2 and the back base material 3, the core on the back surface of the front base material 2 rather than an aspect in which a backing material such as a resin sheet is attached to the back side of the front base material 2. The material 4 can be firmly adhered, and the performance required for the roof material, such as rain sound property, heat insulating property, and tread resistance, can be improved.

  There is no restriction | limiting in particular as a raw material of the core material 4, Urethane, phenol, a nurate resin etc. can be used. However, it is essential to use incombustible certified materials for roofing materials. In the incombustible material qualification test, an exothermic test based on the ISO 5660-1 cone calorimeter test method is performed. When the foamed resin to be the core material 4 is urethane having a large calorific value, the thickness of the core material 4 can be reduced, or the foamed resin can contain inorganic foam particles.

  The reinforcing member 5 is a cylindrical member having a hole 50 as shown in FIG. However, the outer shape of the reinforcing member 5 may be another shape such as a square. 2 and 3, the reinforcing member 5 is embedded in the core member 4 so that the hole 50 overlaps the fastening hole 20 (position where the fastening member 8 is driven into the metal roofing material 1). 8 is driven into the metal roofing material 1 so as to pass through the hole 50 of the reinforcing member 5.

  The reinforcing member 5 reinforces the surface base material 2 at the driving position of the binding member to the metal roof material 1 and is configured to be harder than the foamed resin constituting the core material 4. The reinforcing member 5 is disposed in contact with the front substrate 2 and the back substrate 3. In other words, the thickness 51 of the reinforcing member 5 is equal to the distance between the inner surface of the front substrate 2 and the inner surface of the back substrate 3. Contact between the reinforcing member 5 and the front substrate 2 and the back substrate 3 is surface contact.

  As a material of the reinforcing member 5, for example, metal or resin can be used. As the metal material, a plated steel plate, a stainless steel plate, and a coated steel plate can be used. When using a resin material, it is preferable to use a resin of UL94 standard grade V-0 or higher (for example, polyvinylidene fluoride, silicone, Teflon (registered trademark), cross-linked polyethylene, etc.), which is a flame retardant certification standard for resins. By using the resin material, when the metal roof material 1 is cut to adjust the size of the metal roof material 1, it can be avoided that the reinforcing member 5 inhibits the cutting of the metal roof material 1. The space between the end surfaces of the reinforcing members 5 in contact with the front base material 2 and the back base material 3 is preferably solid, but has a strength that can support a load assumed to be applied to the metal roofing material 1. When the material of the reinforcing member 5 has, the space between the end surfaces of the reinforcing member 5 may be hollow. When the space between the end faces of the reinforcing member 5 is hollow, it is preferable that the end face of the reinforcing member 5 is supported by at least the inner peripheral wall and the outer peripheral wall of the reinforcing member 5.

  The outer diameter of the reinforcing member 5 is preferably greater than or equal to the outer diameter of the head of the tightening member, and more preferably, the outer diameter of the reinforcing member 5 is greater than or equal to twice the outer diameter of the head of the tightening member.

  Next, FIG. 5 is explanatory drawing which shows the roofing method using the metal roof material 1 of FIG. 1, and FIG. 6 is a side view which shows the two metal roof materials 1 which mutually overlap in FIG. As shown in FIG. 5, when roofing is performed using the metal roofing material 1 of FIG. 1 (when a roof is made), a plurality of metals are abutted against each other in the direction 6 parallel to the eaves of the building. The roofing material 1 is arranged side by side on the roof base. At this time, each metal roofing material 1 is arrange | positioned on a roof base | substrate so that the longitudinal direction 1L may be along the direction 6 parallel to the eaves of a roof, and the transversal direction 1S may be along the eaves-ridge direction 7 of a roof.

  After the metal roofing material 1 is disposed on the roof base, a fastening member 8 such as a screw or a nail is driven into the metal roofing material 1 to fix the binding member 8 to the roof base. At this time, the binding member 8 is driven into each metal roof material 1 so as to pass through the hole 50 of the reinforcing member 5. The periphery of the hole 50 is reinforced by the reinforcing member 5, and it is avoided that the surface base material 2 is depressed due to the driving of the binding member 8.

  Further, with respect to the eaves ridge direction 7, the eaves side end 11 of the metal roofing material 1 on the ridge side (upper side in FIG. 5) is placed on the ridge side end 10 of the metal roofing material 1 on the eaves side (lower side in FIG. 5). Each metal roofing material 1 is arrange | positioned on a roof base | substrate, overlapping. At this time, the ridge-side metal roofing material 1 is arranged such that the fastening hole 20 is positioned in the vicinity of the ridge-side corner 10a of the eaves-side metal roofing material 1, that is, the reinforcing member 5 overlaps the ridge-side corner 10a. Placed in. By overlapping the reinforcing member 5 on the ridge side corner portion 10a, the back surface of the eaves side metal roofing material 1 is prevented from being crushed by being pressed against the ridge side corner portion 10a.

  In such a metal roofing material 1 and a roofing method using the same, a plurality of reinforcing members 5 embedded in the core material 4 and disposed in contact with the front base material 2 and the back base material 3 are provided. The reinforcing member 5 can receive a load applied to the front substrate 2. Thereby, even if a load is applied to the surface base material 2, the possibility that a dent will arise in the surface base material 2 can be made low. Thereby, the possibility of the problem on the external appearance resulting from the hollow in the surface base material 2, and the fall of the wind-resistant performance of the metal roofing material 1 can be reduced.

  Further, since the reinforcing member 5 is in surface contact with the front base material 2 and the back base material 3, the reinforcing member 5 can receive the load applied to the front base material 2 more reliably. It is possible to more reliably reduce the possibility that a dent will be formed in the surface.

  Further, since the reinforcing member 5 is arranged so that the hole 50 overlaps the driving position of the fastening member 8 to the metal roofing material 1, the driving position of the fastening member 8 can be reinforced. The possibility that a depression will occur in the substrate 2 can be reliably reduced.

  Furthermore, since the reinforcing member 5 is disposed at a position where it is overlapped with the corner portion 10a of another metal roof material, the back surface of the metal roof material 1 is prevented from being crushed by being pressed against the corner portion 10a. Can do. Crushing of the back surface of the metal roofing material 1 causes a decrease in the wind pressure resistance performance of the metal roofing material 1. For this reason, the fall of the wind-resistant performance of the metal roof material 1 can be avoided by preventing the back surface of the metal roof material 1 from being crushed.

  Further, since the reinforcing members 5 are spaced apart from each other in the longitudinal direction 1L of the metal roofing material 1, the back surface of the metal roofing material 1 can be prevented from being crushed at a plurality of locations in the longitudinal direction 1L. A decrease in wind pressure performance can be avoided more reliably.

  Furthermore, since the reinforcing member 5 is made of a resin of UL94 standard grade V-0 or higher, the reinforcing member 5 inhibits the cutting of the metal roofing material 1 while maintaining the flame-retardant performance of the metal roofing material 1. It can be avoided.

  Further, since the reinforcing member 5 is made of metal, the strength of the reinforcing member 5 can be increased as compared with the case where resin is used as the material of the reinforcing member 5, and there is a possibility that the surface base material 2 will be depressed. It can be lowered more reliably.
