  Hereinafter, a metal roofing material for repairing flat slate tiles according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a plan view showing a part of a roof in which flat slate roof tiles 1 are stacked stepwise from an eave side (below) to a ridge side (upper) as indicated by a two-dot chain line. A roofing material (hereinafter simply referred to as “metal roofing material”) 2 is placed on an existing flat plate slate tile 1 and is interposed between the flat plate slate tile 1 and the metal roofing material 2 with a predetermined space therebetween. It is fixed together with the slate roof tile 1 by a fixing member 5 fixed to the base plate. Hereinafter, in each of the above-described components, the water upper side (ridge side) is described as the upper end or upper end portion, and the water lower side (eave side) is described as the lower end or lower end portion.

  The metal roofing material 2 has a flat plate shape. For example, the horizontal length (horizontal width) is slightly longer than the horizontal width of the flat slate tile 1 (for two pieces), and the vertical length (vertical width). Is a rectangular shape elongated in the lateral direction wider than the working width of the flat slate roof tile 1. As shown in FIG. 2, the upper end 2b of the flat plate portion 2a is folded back into a substantially U-shape that is slightly open when viewed from the side, and the lower end 2c is a side facing the entire width. As viewed from the bottom, it is bent into a substantially square U shape.

  The upper surface 2d of the upper end portion 2b is elastically brought into contact with the lower surface of the flat plate slate roof tile 1 on the upper side of the flat plate slate roof tile 1 to be covered, and the end surface 2e bites into the lower surface. Further, the end surface 2e can be engaged with a locking claw 7 as a locking portion of the fixing member 5 described later, and also has a function as a locking portion.

  The lower end 2c having a substantially square U shape has a central portion (front plate portion) 2f formed higher than the plate thickness of the flat plate slate roof tile 1, and the upper end portion (terminal) 2h of the lower plate portion 2g is substantially U on the inside. It is folded in a letter shape. The lower plate portion 2g can be inserted into the gap between the tip of the flat plate slate tile 1 to be covered and the lower flat plate slate tile 1 and the upper surface 2i is in contact with the lower surface of the flat plate slate tile 1 to be covered or a slight gap. The end surface 2j has a function as a locking portion that engages with the locking claw 6 of the fixing member 5.

  For example, in the case of a structure in which two flat plate slate tiles are stacked, the metal roofing material 2 to be covered on the flat plate slate roof tile has a height of the central portion 2f of the lower end 2c. It is the height of 2 sheets according to.

  The metal roofing material 2 is formed of, for example, a galvalume steel plate having excellent corrosion resistance, and has an antirust coating on the entire surface and a predetermined color coating on the surface. A backup material 3 is attached to the back surface of the flat plate portion 2 a of the metal roof material 2. The backup material 3 is formed of, for example, urethane or a polystyrene foam member, and has a function as a heat insulating material and a sound insulating material.

  The fixing member 5 is called a so-called hanger, and is used to fix the metal roofing material 2 by being fixed to the existing flat slate tile 1. As shown in FIGS. 3 to 5, the fixing member 5 is formed by bending a belt-shaped steel plate into a substantially square U shape when viewed from the side, and is attached to the front end portion of the flat plate slate roof tile 1. The upper plate portion 5a is slightly longer than the lower plate portion 5b, and the lower portion 5d of the central portion 5c is connected to the lower plate portion 5b with an inclined rear surface. The central portion 5c may be formed in a semicircular shape as shown by a two-dot chain line in FIG. Forming in a semicircular shape in this way facilitates molding.

  A rib 5e having a concentric circular shape when viewed from above and bulging upward in a substantially semicircular shape when viewed from the side surface, for example, a half shape of a donut, is formed at the approximate center of the upper end portion of the upper plate portion 5a. A screw hole 5f is formed on the surface. Furthermore, one end is connected to the rib 5e on both sides of the upper plate portion 5a, and the other end extends to the lower end side (center portion 5c side) by an appropriate length, and has a substantially semicircular shape upward and the same height as the rib 5e. An elongated rib 5g that bulges out is formed. As shown in FIGS. 4 and 5, the screw hole 5 f is located at the end of the lower plate portion 5 b (above the upper end (ridge side).

  As shown in FIGS. 4 and 5, a rib 5 h is formed on the upper end of the lower plate portion 5 b below the plate surface and swells in a substantially trapezoidal shape from the lower end side along the upper end direction (vertical direction). Further, locking claws 6 as locking portions are formed on both sides of the lower end portion of the lower plate portion 5b, and locking claws 7 as locking portions are formed between the locking claws 6 and the ribs 5h. ing. The height of the locking claw 6 is set lower than that of the rib 5 h, and the height of the locking claw 7 is set to the same height as the locking claw 6.

  4 and 5, the rib 5h is formed to the full width of the lower plate portion 5b. However, the rib 5h is not limited to this, and has a width suitable for other positions. For example, the rib 5h is formed at the center of the upper end of the lower plate portion 5b. You may form in the width | variety of about 1/3 of a width | variety. Moreover, the cross-sectional shape may be substantially arc-shaped along the upper end direction (vertical direction) from the lower end side.

  As shown in FIG. 5, the locking claw 6 has a substantially saw-tooth shape standing from below the plate surface of the lower plate portion 5 b and from the lower end toward the upper end (upward) as shown in FIG. 5. Thus, the lower surface 6a is slightly concaved inward slightly from the lower end to the upper end, and both side portions 6b are formed substantially perpendicular to the lower plate portion 5b and open upward.

  The opening 6d has a square shape, and both end surfaces thereof, that is, end surfaces 6c of the both side portions 6b are formed so as to be slightly inclined from the end surface 6e of the lower surface 6a to the lower plate portion 5b and toward the lower end side. Both end surfaces 6c are substantially locking claws. The locking claw 7 is also formed in the same manner as the locking claw 6. The fixing member 5 is integrally formed of a galvalume steel plate having excellent corrosion resistance, like the metal roofing material 2.

  The procedure for repairing an existing flat slate tile roof with the metal roof material 2 will be described below. First, the headboard (holding plate) that fixes the roof cover (not shown) of the roof and the flat slate tile on the uppermost stage to the base plate is removed. Next, the fixing members 5 are arranged and fixed to the uppermost flat plate slate tile at predetermined intervals in the lateral direction of the roof. As shown in FIG. 1, the flat slate tiled roof is arranged such that flat slate tiles 1 are juxtaposed in the horizontal (width) direction of the roof and the end faces of the adjacent flat slate tiles 1 on the left and right are abutted. Therefore, the fixing member 5 is disposed, for example, at the butting position of the flat slate roof tiles 1 adjacent to the left and right shown in FIG.

  Then, as shown in FIG. 7, a fixing member 5-1 is attached to the front end of the first (uppermost) flat slate tile 1-1 from the ridge side, and the upper plate portion is placed on the upper surface of the flat slate tile 1-1. 5a is brought into contact, and the lower plate portion 5b is inserted until the lower portion 5d of the central portion 5c comes into contact with the gap between the flat plate slate roof tile 1-1 and the lower second flat plate slate roof tile 1-2. The lower plate portion 5b contacts the lower surface of the flat plate slate roof tile 1-2. In FIG. 7, hatching of the flat slate roof tile 1 and the fixing member 5 is omitted in order to avoid complication of the drawing.

  Next, the packing 8 is put into the rib 5e of the upper plate portion 5a, and the upper plate portion 5a is fixed to the base plate 15 and the rafter 16 together with the flat plate slate roof tile 1 with screws 9. The head of the screw 9 has substantially the same height as the rib 5e. The packing 8 is in close contact with the rib 5e and the screw 9 when the screw 9 is screwed with a round rubber plate, and asbestos chips generated when the screw 9 is screwed into the flat slate tile 1-1 are scattered from the screw hole 5f to the outside. Is effectively prevented. The packing 8 is not necessarily used.

  In this state, the rib 5h formed on the lower plate portion 5b of the fixing member 5 abuts on the upper surface of the second-stage flat plate slate roof 1-2, and the lower end side is pushed up with the rib 5h as a fulcrum, so that the first-stage Between the flat plate slate tile 1-1 and the flat plate slate tile 1-2 of the second stage, a gap S-1 that opens in a tapered shape toward the front end side of the flat plate slate roof tile 1-1 is formed. And the front-end | tip of the latching nail | claws 6 and 7 is spaced apart slightly from the upper surface of the flat slate roof tile 1-2.

  Next, the first-stage flat plate slate 1-1 is covered with a metal roofing material 2-1, and the lower plate portion 2g is placed under the flat plate slate tile 1-1 and the lower plate portion 5b of the fixing member 5-1, and the flat plate. Insert into the gap S-1 with the slate roof 1-2. The lower plate portion 2g can be easily inserted into the lower plate portion 2g of the metal roofing material 2-1, since the lower portion 5d of the central portion 5c of the fixing member 5-1 forms an inclined surface rearward.

  Further, the upper end portion 2h of the lower plate portion 2g folded back in a U shape can easily get over while sliding because the lower surface 6a of the locking claw 6 is slightly concave on the inside. The lower plate portion 2g can be easily inserted. Then, the upper surface 2i of the upper end portion 2h of the lower plate portion 2g folded back in contact with the lower surface of the flat plate slate roof tile 1-1, and the end surface 2j is both end surfaces 6c of the locking claws 6 of the fixing member 5-1. (See FIG. 6). Thereby, the lower end part 2c of the metal roof material 2-1 is locked to the fixing member 5-1.

  The upper part of the metal roofing material 2-1 is held by a headboard (not shown) and fixed to a base plate and a rafter together with a flat slate tile 1-1 by a screw, and a portion extending upward from the headboard leaves an appropriate length. Is cut and bent upward. And the ridge cover which is not illustrated is attached. In this way, the metal roofing material 2-2 is placed on the uppermost flat plate slate tile 1-1. The ribs 5e and 5h of the fixing member 5-1 and the heads of the screws 9 are absorbed by the backup material 3 attached to the back surface of the metal roofing material 2-1, and due to these, the metal roofing material 2-1. The flat plate portion 2a is not deformed.

  Next, the fixing member 5-2 is fixed to the second-stage flat plate slate roof 1-2 in the same manner as described above, and a gap S-2 is formed between the lower flat plate slate roof tile 1-3. Form. Then, the flat roof slate 1-2 is covered with a metal roof material 2-2, the upper end 2b is inserted into the gap S-1, and the lower plate 2g is inserted into the gap S-2. The upper surface 2d of the upper end portion 2b comes into contact with the lower plate portion 5b of the fixing member 5-1 and the back surface of the flat plate slate roof tile 1-1. The end surface 2e of the upper surface 2d is inserted deeper than the locking claw 7 and faces the locking claw 7 with a slight gap.

  Further, the upper surface 2i of the upper end portion 2h of the lower plate portion 2g which is folded back in U shape comes into contact with the lower plate portion 5b of the fixing member 5-2 and the lower surface of the flat plate slate tile 1-1, and the end surface 2j is the fixing member 5. Locked to both end faces 6c of the locking claw 6 of -2. As a result, the metal roof material 2-2 is covered with the second-stage flat plate slate tile 1-2 and locked to the fixing member 5-2. In this way, the metal roofing material 2 is applied to the existing flat slate tile in order from the ridge side (upper) to the eaves side (lower), and then repaired.

  Alternatively, the fixing members 11 may be attached as described above, and then the metal roofing material 2 may be attached alternately. Alternatively, the existing flat slate tile 1 may be attached to a predetermined position from the ridge side to the eaves side. Alternatively, the fixing member 5 may be attached to the metal roofing material 2 later.

  As described above, when the end surface 2e of the upper surface 2d of the metal roofing material 2 is inserted deeper than the locking claw 7 of the fixing member 5, the dimension of the working width of the existing flat slate tile 1 is slightly changed. Even in this case, it becomes possible to absorb the dimensional difference (change). The metal roofing material 2 does not necessarily have to be locked with the locking claw 7 because the end surface 2e bites into the lower surface of the flat slate tile 1 and is locked. Therefore, the locking claw 7 of the fixing member 5 may be omitted.

  However, if for some reason a large force acts downward on the metal roofing material 2 so that the end surface 2j of the lower plate portion 2g is disengaged from the locking claw 6 of the fixing member 5 and the metal roofing material 2 is displaced, the end surface 2e It is possible to prevent the metal roof material 2 from slipping off by locking with the locking claw 7. Of course, the end surface 2j of the lower plate portion 2g may be locked to the locking claw 6 of the fixing member 5, and the end surface 2e may be locked to the locking claw 7.

  Then, by carrying out the work from the ridge side toward the eaves side, the work is not carried on the newly struck metal roofing material 2, and scratches and dirt can be minimized. In addition, it is possible to minimize the walking of the finished surface of the newly struck metal roofing material, it can prevent dirt and scratches and is easy to cure without any problems even if it rains during the construction. . Furthermore, the worker's construction posture is not unreasonable, and the fatigue level can be reduced.

  Furthermore, the metal roofing material 2 can be covered with the step of the existing flat slate tile 1, and the design of the existing roof can be maintained. In addition, the heat-insulating and sound-insulating backup material 3 adhered to the back surface of the metal roofing material 2 is combined with the existing flat slate tile 1 to affect the heat in the summer, cooling in the winter and rain noise. It can be effectively suppressed.

  8 and 9 show a modification of the fixing member according to the present invention. The fixing member 11 has an upper portion 11a of a flat plate folded back in a substantially U shape so that an upper plate portion 11b is brought into the vicinity of a substantially central portion of the lower plate portion 11c, and a terminal 11d is bent upward (outside) at a substantially right angle. Is formed. The terminal 11d is a locking portion that contacts and locks the front end surface of the existing flat slate roof tile 1. A plurality of locking claws 12 as locking portions are formed on the upper plate portion 11b from the vicinity of the bent portion with the terminal 11d at a predetermined interval in the direction of the folded portion.

  The locking claw 12 has a substantially serrated shape standing below the plate surface of the upper plate portion 11b and from the terminal side (lower end side) toward the folded portion (upper end side), and the lower surface 12a is substantially half in the width direction. It has a circular shape, has a triangular shape that widens from the lower end toward the upper end, and the upper end is open. The opening has a substantially semicircular shape, and its end surface 12b is a substantial locking claw.

  The height of the locking claw 12 is gradually lowered from the terminal side toward the folded portion, and the upper end portion 2b of the metal roof material 2 is easily inserted.
