It is a side view. The roof structure shown in FIG. 1 and FIG. 2 is one in which a plurality of flat roof materials 1 having a flat outer shape are arranged side by side on a roof base.

  Specifically, with respect to the eaves direction 2 of the roof, the flat roof materials 1 are disposed with their side ends butting against each other. Further, as particularly shown in FIG. 2, with respect to the eaves building direction 3 of the roof orthogonal to the eaves direction 2, each flat plate roofing material 1 is a flat plate roofing material 1 on the ridge side on the flat plate roofing material 1 of the eaves side. A part of is arranged in piles.

  Further, the flat roof material 1 on the ridge side with respect to the eaves direction 2 is offset from the flat roof material 1 on the eaves side by a half of the extension width of the flat roof material 1 along the eaves direction 2. That is, the butt portion of the side edge of the flat roof material 1 on the ridge side is disposed offset from the butt portion of the side edge of the flat roof material 1 on the eaves side with respect to the eaves direction 2.

  Each flat roof material 1 is tightened to the roof base by driving in a tightening member 4 such as a nail or a screw. The tensioning member 4 is covered and concealed by the flat roof material 1 on the ridge side, and only a portion of the tensioning member 4 is shown by a broken line in FIG.

  For the following description, a plurality of flat roof materials 1 arranged in the eaves direction 2 may be referred to as a single flat roof material 1 in a row. According to this expression, the first row flat roof 1 (1A), the second row flat roof 1 (1B) and the third row flat roof 1 (1C) appear in FIG. It will be. The second row flat roof material 1B is disposed on the ridge side of the first row flat roof material 1A, and the third row flat roof material 1C is disposed on the ridge side of the second row flat roof material 1B. The tension members 4 (4B) driven into the second row of flat roof materials 1B penetrate the first row of flat roof materials 1A to reach the roof foundation. In addition, the bonding members 4 (4C) driven into the third row of flat roof materials 1C penetrate the second row of flat roof materials 1B to reach the roof foundation.

  In addition, the terms of the first to third rows described above only represent three rows of flat roof materials 1 disposed in a shifted manner in the eaves ridge direction 3, and the position of each row in the entire roof structure It is not limited. That is, another flat roof material 1 may be disposed on the eaves side of the flat roof material 1A in the first row.

  3 is a front view showing the flat roof material 1 of FIG. 1, FIG. 4 is a rear view showing the flat roof material 1 of FIG. 3, and FIG. 5 is a flat plate along the line V-V of FIG. FIG. 2 is a cross-sectional view of a roof material 1; As shown to FIGS. 3-5, the flat plate roof material 1 has a planar view substantially rectangular external shape which has the longitudinal direction 1L (width direction) and the transversal direction 1S (depth direction). The flat roof material 1 is disposed on the roof base so that the longitudinal direction 1L is along the eaves direction 2 of the roof and the short direction 1S is along the eaves direction 3 of the roof (see FIG. 1). As shown in FIGS. 3 to 5, the flat roof material 1 is a metal roof material having a front substrate 12, a back substrate 13 and a core material 14.

  The front base material 12 is a metal member made of a metal plate, and is a member that appears on the outer surface of the roof when the flat roof material 1 is disposed on the roof base. As particularly shown in FIG. 5, the front base 12 is provided with a box-like main body 120 having a top plate 120 a and a peripheral wall 120 b.

  As shown in FIG. 3, in the top plate 120 a of the front substrate 12, a plurality of bonding holes 121 are provided so as to be separated from each other in the longitudinal direction 1 L (eave direction 2) of the flat roof material 1. The fastening holes 121 indicate the positions where the fastening members 4 (see FIG. 1) are driven into the flat roof material 1. In the present embodiment, although it is described that the binding holes 121 are provided in the front substrate 12, non-opening marks indicating the positions where the binding members 4 are driven, such as printed symbols and irregularities, are attached. It may be provided on the top 120 a instead of the hole 121.

  The peripheral wall 120 b of the front substrate 12 is provided with a first side surface 122, a second side surface 123, a ridge side end surface 124 and an eaves side end surface 125.

  The first and second side surfaces 122 and 123 are respectively provided on both sides in the longitudinal direction 1 L of the flat roof material 1. The second side surface 123 is adapted to be positioned on the ridge side of the first side surface 122 when the flat roof material 1 is disposed on the roof foundation. The second side surface 123 is disposed at a position projecting outward in the longitudinal direction 1 L of the flat roof material 1 more than the first side surface 122.

  The first side surface 122 is a side surface formed by folding back a metal plate extending outward in the longitudinal direction 1L from the lower end of the first side surface 122 to the back side of the front base 12 so as to hold the back base 13. A flange 122a is provided. Since the side surface flange 122a is provided integrally with the main body portion 120, the durability of the flat roof material 1 against the external force which tends to warp the flat roof material 1 along the straight line along the longitudinal direction 1L Wind pressure performance has been improved. The protrusion width of the side surface flange 122 a from the first side surface 122 is equal to or less than the protrusion width of the second side surface 123 from the first side surface 122.

  The second side surface 123 is not provided with a flange. This is because the flange extending from the second side surface 123 is cut and removed after the box-shaped main body portion 120 is formed.

  The ridge side end face 124 is positioned at one end along the short direction 1S, and is adapted to be positioned on the ridge side when the flat roof material 1 is disposed on the roof foundation. The ridge-side end surface 124 is provided with a straight portion 124 a and a pair of oblique portions 124 b. The straight portion 124a extends linearly along the longitudinal direction 1L. The oblique portions 124 b are disposed on both sides of the linear portion 124 a so as to connect the linear portion 124 a and the second side surface 123. The oblique portion 124 b extends obliquely with respect to the linear portion 124 a so as to approach the eaves side (the other end side along the short direction 1 S) as the second side surface 123 is approached.

  As particularly shown in FIGS. 3 and 5, in the straight portion 124 a of the ridge-side end surface 124, a metal plate extending outward from the lower end of the ridge-side end surface 124 along the short direction 1S is the back substrate 13. The ridge side flange 124c formed by being folded back on the back side of the front base material 12 so that it may be carried is provided.

  No flange is provided on the inclined portion 124 b of the ridge-side end surface 124. This is because, similar to the above-described second side surface 123, after the box-shaped main body portion 120 is formed, the flange extending from the oblique portion 124b is cut and removed. However, a flange similar to the ridge side flange 124c may be provided on the inclined portion 124b.

  The eaves side end face 125 is located at the other end along the short direction 1S, and is adapted to be located at the eaves side when the flat roof material 1 is disposed on the roof base. In the flat plate roofing material 1 of the present embodiment, the eaves-side end face 125 is constituted only by a straight portion extending along the longitudinal direction 1L. However, the eaves-side end face 125 may have other shapes.

  The eaves side end face 125 is formed by folding back a metal plate extending outward from the lower end of the eaves side end face 125 along the short direction 1S to the back side of the front base 12 so as to hold the back base 13. An eaves side flange 125a is provided.

  The ridge side flange 124c and the eaves side flange 125a are extended along the longitudinal direction 1L, and prevent the flat roof material 1 from warping along the direction intersecting the longitudinal direction 1L.

  As a metal plate which is a material of the surface base material 12, a hot-dip galvanized steel sheet, a hot-dip aluminum plated steel plate, a hot-dip galvanized steel sheet, a hot-dip galvanized stainless steel sheet, a stainless steel plate, an aluminum plate, a Ti plate, a hot-dip galvanized steel sheet It is possible to use a plated steel plate, a painted molten Al plated steel plate, a painted molten Zn-based plated stainless steel plate, a painted molten Al plated stainless steel plate, a painted stainless steel plate, a painted Al plate or a painted Ti plate. When making the surface base material 12 into box shape, it is preferable to draw-process a steel plate and to comprise the surface base material 12. This is because work hardening occurs on the peripheral wall 120b by drawing the steel plate, and the wind pressure performance of the flat roof material 1 can be improved. Moreover, it is because the surrounding wall 120b can be made into the wall surface which follows the circumferential direction of the surface base material 12. FIG.

  The back substrate 13 is a member disposed on the back side of the front substrate 12 so as to close the opening of the main body 120. As the back substrate 13, a lightweight material such as aluminum foil, aluminum-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 13, it is possible to avoid an increase in the weight of the flat roof material 1.

  The core 14 is made of, for example, a foamed resin, and is filled between the main body 120 and the back base 13. There is no restriction | limiting in particular as a raw material of the core material 14, A urethane, a phenol, a nurate resin etc. can be used. However, for roofing materials, it is essential to use non-combustible certified materials. In the noncombustible material qualification test, a heat generation test in accordance with the ISO 5660-1 corn calorimeter test method is performed. In the case where the foamed resin to be the core member 14 is urethane or the like having a large calorific value, the thickness of the core member 14 can be reduced or inorganic foamed particles can be contained in the foamed resin. The core material is applied to the back surface of the front surface substrate 12 rather than a mode in which a backing material such as a resin sheet is attached to the back surface of the front surface substrate 12 by filling the foamed resin between the main body 120 and the back substrate 13. 14 can be firmly adhered, and the performance required for a roofing material such as rain noise, heat insulation and anti-stepping resistance can be improved.

  Next, FIG. 6 is a front view showing the plate-like cover material 5 used in the method of repairing a roof according to the embodiment of the present invention, and FIG. 7 is a plate-like cover material along line VII-VII in FIG. FIG. 8 is a cross-sectional view of the plate-like cover member 5 taken along the line VIII-line VIII of FIG.

  The plate-like cover material 5 shown in FIG. 6 is a flat plate roof material which is damaged when one flat plate roof material 1 of the plurality of flat plate roof materials 1 arranged as shown in FIG. 1 is damaged. It is for repairing 1. As will be described later with reference to the drawings, the plate-like cover material 5 is disposed so as to overlap the flat roof material 1 so as to cover the top plate 120 a of the damaged flat roof material 1. 6-8, the flat roof material 1 in which the plate-shaped cover material 5 is piled up is represented by the dashed-two dotted line.

  Similar to the flat roof material 1, the plate-like cover material 5 has a rectangular outline in plan view having a longitudinal direction 5L (width direction) and a lateral direction 5S (depth direction). Although the material of the plate-like cover material 5 is arbitrary, it is preferable that it is the same material as the top plate of the flat plate roof material 1. As described above, when the flat roof material 1 is formed of the metal roofing material in which the metal plate is used for the front substrate 12, the plate-like cover material 5 may be formed of the metal plate in the same manner as the front substrate 12. it can. For example, in the case where the top plate 120 a of the flat roof material 1 is subjected to surface treatment such as painting or concavo-convex processing, it is preferable that the same surface treatment is applied to the surface of the plate-like cover material 5. In the same surface treatment referred to here, not only strictly the same surface treatment but also the plate-like cover material 5 when the front substrate 12 of the flat plate roof material 1 and the plate-like cover material 5 are viewed several meters apart The same kind of surface treatment is also included which gives the impression that the surface of the same is obviously different from or the same as the surface of the surface substrate 12.

  The plate-like cover member 5 is provided with a pair of side end portions 50, an eaves side end portion 51 and a ridge side end portion 52.

  As shown in FIG. 7, the side end 50 of the plate-like cover material 5 is provided along the top plate 120 a of the flat roof material 1. In other words, the side end 50 is not provided with a vertical wall along the peripheral wall 120 b of the flat roof material 1. When the side wall 50 is not provided with the vertical wall, when inserting the plate-like cover member 5 between the flat plate roof members 1 as described later, the plate-like cover member 5 is formed along the straight line along the longitudinal direction 5L. It can be easily warped to the front or back side. The width of the flat cover 5 along the longitudinal direction 5L is equal to the width of the top 120a of the flat roof material 1 along the longitudinal 5L or slightly smaller than the width of the top 120a. ing.

  The eaves side end 51 is provided with a vertical wall 51a along the peripheral wall 120b of the flat roof material 1 as shown in FIG. By providing the vertical wall 51a at the eaves side end 51, it is possible to prevent the plate-like cover material 5 from being warped along a straight line along the short direction 5S. Further, by abutting the vertical wall 51a to the peripheral wall 120b, the plate-like cover member 5 can be reliably positioned along the short direction 5S. Although the vertical wall 51a is provided at the eaves side end 51 in the present embodiment, the vertical wall 51a may be omitted. In addition, an extension wall which holds or covers the eaves-side flange 125a of the flat roof material 1 may be extended from the tip of the vertical wall 51a.

  The ridge side end 52 is provided with a straight portion 52 a and a slant portion 52 b. The straight portion 52a extends linearly along the longitudinal direction 5L. The straight portion 52a is extended at a substantially central position of the plate-like cover member 5 along the longitudinal direction 5L. The oblique portions 52 b are disposed on both sides of the linear portion 52 a so as to connect the linear portion 52 a and the side end 50. In addition, the inclined portion 52 b is extended obliquely with respect to the straight portion 52 a so as to be closer to the eaves side as the side end portion 50 is approached.

  The width between the straight part 52a along the short direction 5S and the eaves side end 51 is the eaves side end of the first row flat roof material 1A along the eaves ridge direction 3 shown in FIG. It is preferable to be larger than the separation distance D1 between the flat roof material 1C and the eaves side end. By this configuration, when the plate-like cover member 5 is inserted between the first row flat plate roof member 1A and the second row flat plate roof member 1B, it is covered by the third row flat plate roof member 1C. The plate-like cover material 5 can be extended below the butt part of the side edge of the flat roof material 1B of the 2nd row which is not hidden (refer to Drawing 10). Thereby, it is possible to prevent moisture entering from the butt portion of the side edge of the flat roof material 1B in the second row from entering between the plate-like cover material 5 and the flat roof material 1A in the first row.

  The ridge side end portion 52 is provided with a water return portion 52 c in which a plate member constituting the plate-like cover member 5 is folded back from the back surface side to the front surface side. By providing the water return part 52c at the ridge side end 52, the water invading from the butt portion of the side edge of the flat plate roofing material 1B in the second row exceeds the ridge side end 52 and the plate-like cover member 5 and the first It is possible to avoid intruding between the row of flat roof materials 1A.

  At the eaves-side end of the first row flat plate roofing material 1A, a binding member 4B which is driven into the second row flat plate roofing material 1B penetrates. When the width between the straight part 52a along the short direction 5S and the eaves side end 51 is increased, interference between the binding member 4B and the plate-like cover member 5 driven into the second row flat roof material 1B is possible Sex is high. By providing the inclined portion 52b at the ridge side end 52 as described above, the possibility of interference between the tension member 4B and the plate-like cover member 5 driven into the flat roof material 1B in the second row is reduced. Can.

  Next, a method of repairing a roof according to the embodiment of the present invention will be described. In addition, the repair method of the roof of this Embodiment is corresponded to the manufacturing method of the roof structure repaired. FIG. 9 is an explanatory view showing a roof repair method according to the embodiment of the present invention, and FIG. 10 is an explanatory view showing a roof structure to which the roof repair method of FIG. 9 is applied.

In the roof structure in which 1 C is arranged, it is assumed that the top plate of the flat roof material 1A in the first row is damaged. At this time, insert the plate-like cover material 5 between the first row flat plate roof material 1A and the second row flat plate roof material 1B (between the eaves side flat plate roof material and the ridge side flat plate roof material) As shown in FIG. 10, the top plate 120a of the flat roof material 1A in the first row is covered with the plate-like cover material 5. Thereby, the top plate 120a can be repaired while leaving the damaged first row flat roof material 1A. That is, it is possible to save time and effort for cutting the connecting member for tightening the flat roof material 1A in the first row and removing the flat roof material 1A in the first row. This configuration is particularly useful when the bonding members 4B driven into the second row of flat roof materials 1B also penetrate the first row of flat roof materials 1A.

  Before the insertion of the plate-like cover material 5, apply an adhesive to the back surface of the plate-like cover material 5, and after the insertion of the plate-like cover material 5, adhere the plate-like cover material 5 to the flat roof material 1A of the first row. Can. Further, for example, a tension member such as a nail or a screw may be driven into the plate-like cover material 5 after the plate-like cover material 5 is inserted, thereby securing the plate-like cover material 5 to the roof base. Bonding and tightening of the plate-like cover material 5 may be performed either one or both.

  In the insertion of the plate-like cover member 5, the vertical wall 51a (see FIG. 8) provided at the eaves-side end 51 of the plate-like cover member 5 abuts or approaches the peripheral wall 120b of the first row flat plate roof material 1A. To be done. At the time of insertion of the plate-like cover member 5, the side edge 50 of the plate-like cover member 5 is not provided with a vertical wall along the peripheral wall 120b of the flat roof material 1, so the plate along the straight line along the longitudinal direction 5L. Cover material 5 can be warped.

Thereby, it is possible to prevent moisture entering from the butt portion of the side edge of the flat roof material 1B in the second row from entering between the plate-like cover material 5 and the flat roof material 1A in the first row.

  According to such a roof repair method and the roof structure, since the top plate 120a of the flat roof material 1 on the eaves side is covered with the plate-like cover material 5, it is possible to save the trouble of cutting the binding member 4 and damage The flat roof material 1 can be repaired more efficiently. This configuration is particularly useful when the flat roof material 1 is formed of a metal roof material having the front substrate 12, the back substrate 13, and the core material 14.

  Moreover, since the plate-like cover material 5 is comprised by the metal plate similarly to the surface base material 12, it can avoid that the plate-like cover material 5 stands out by a difference with the surrounding flat roof material 1. FIG.

  Furthermore, the plate-like cover material 5 inserted between the first row flat plate roof material 1A and the second row flat plate roof material 1B extends below the eaves-side end of the third row flat plate roof material 1C. Since it exists, it is avoided that the moisture which invades from the butt part of the side edge of the flat roof material 1B of the 2nd row gets in between the plate-like cover material 5 and the flat roof material 1A of the 1st row. it can.

  Furthermore, the ridge side end portion of the plate-like cover member 5 is provided with a water return part 52 c in which the plate material constituting the plate-like cover member 5 is folded back from the back side to the front side. It is possible to prevent moisture entering from the butt portion of the side edge of the flat roof material 1B from entering the space between the plate-like cover 5 and the flat roof material 1A in the first row beyond the ridge side end 52.

  Further, since the side end portion of the plate-like cover material 5 is provided along the top plate of the flat roof material, the plate-like cover material 5 can be warped along a straight line along the longitudinal direction 5L. The plate-like cover material 5 can be more efficiently inserted between the flat row roofing material 1A in one row and the flat row roofing material 1B in the second row.

  Furthermore, since the vertical wall 51a along the peripheral wall 120b of the flat roof material 1 is provided at the eaves side end of the flat cover material 5, the flat cover material 5 is warped along the straight line along the short direction 5S. While the proof strength to the thing is improved, positioning of the plate-shaped cover material 5 in alignment with the transversal direction 5S can be performed reliably.

  Furthermore, since the plate-like cover material 5 is bonded to the top plate 120 a of the flat plate roof material 1 on the eaves side, detachment of the plate-like cover material 5 from the flat plate roof material 1 can be avoided.

  Moreover, since the plate-like cover material 5 is tightened to the roof base together with the flat roof material 1 on the eaves side, it is possible to prevent the plate-like cover material 5 from coming off the flat roof material 1.

  In the embodiment, the flat roof material 1 is described as being constituted by the metal roof material having the front base material 12, the rear base material 13 and the core material 14. The present invention is also applicable to the case where a flat roofing material is constituted by the roofing material of the present invention.
