<About keraba drainage>
FIG. 5 is a front view showing the keraba drainage 74 of FIG. The keraba drainage 74 is a member for covering the climbing tree 72. The keraba drainage 74 of the present embodiment also covers the end of the field plate 70 on the gable side. The keraba drainage 74 extends in the eaves direction between the eaves edge of the roof and the ridge edge, similarly to the climbing tree 72 and the rafter member 78. The climbing tree 72 is fixed to the field board 70 by a binding member 72d composed of, for example, screws or nails. The binding member 72d of the present embodiment is driven into the climbing tree 72 from above, penetrates the field board 70, and reaches the rafter member 78. In other words, the binding member 72d of the present embodiment fixes the climbing tree 72 to the field board 70 and the rafter member 78. A gable board 79 is arranged on the side of the rafter member 78.

The keraba drainage 74 of the present embodiment can be divided into two members. That is, the keraba drainage 74 of the present embodiment is provided with the drainage member 741 and the keraba member 742.

The drainage member 741 is a member that is overlapped with the field board 70 and covers the side surface 72a on the anti-gable side of the climbing tree 72. The drainage member 741 includes a flat plate-shaped mounting piece 7411, a standing piece 7412 standing up from the end of the mounting piece 7411 on the wife side, and an upper piece 7413 extending from the upper end of the standing piece 7412 to the anti-gable side.

Hangers are attached to the left and right sides of the first roof unit 21, that is, to the side exposed area 211 (see FIG. 3) of the first roof unit 21 and the climbing tree 72, and the first roof unit 21 is mounted using the hangers. Can be lifted.

<About rafter members>
Next, FIG. 6 is a perspective view showing the rafter member 78 of FIG. 3, and FIG. 7 is a front view showing the rafter member 78 of FIG. In addition, in FIG. 6, the field board 70 of FIG. 3 is also shown. The rafter member 78 of the present embodiment is composed of a square metal pipe. Further, the rafter member 78 of the present embodiment has a closed cross section. More specifically, the rafter member 78 of the present embodiment is composed of a rectangular metal pipe having a rectangular cross section having a long wall 780 and a short wall 781. The long wall 780 and the short wall 781 form a wall portion of the rafter member 78. As shown in FIG. 7, the rafter member 78 of the present embodiment is adapted so that the long wall 780 extends in the vertical direction and the field plate 70 of FIG. 3 is placed on the short wall 781. However, the cross-sectional shape of the square metal tube is arbitrary, and may be another shape such as a square or a trapezoid. Since the rafter member 78 is a square metal pipe having a closed cross section, the strength can be ensured and the workability can be improved even if the rafter member 78 is made thinner and lighter. Further, if the rafter member 78 is made of wood, the rafter member 78 may be bent, which may hinder the arrangement of the roof units 21 to 24. By forming the rafter member 78 with a square metal pipe, such a possibility can be reduced.

As the material of the square metal tube, a cold-rolled steel plate, a stainless steel plate, an aluminum plate, or a surface-treated material thereof can be used. Surface treatments include plating and painting. In particular, the plating includes Zn-Al-Mg alloy plating. The wall thickness of the square metal tube can be about 0.8 mm.

The short wall 781 is provided with ribs 783 extending in the longitudinal direction of the rafter member 78. By providing such a rib 783 on the short wall 781, the rigidity of the rafter member 78 with respect to an external force applied to the rafter member 78 along the direction orthogonal to the longitudinal direction of the rafter member 78 can be improved. The rib 783 of the present embodiment has a plurality of recesses arranged at intervals in the width direction of the short wall 781. The plurality of recesses of the present embodiment form the first and second recess groups 7831 and 7832. The first and second recess groups 7831 and 7832 are arranged on both sides of the flat plate portion 7833 formed in the central portion in the width direction of the short wall 781. The rib 783 may have a plurality of convex portions arranged at intervals in the width direction of the short wall 781.

As shown in FIG. 7, the screw 78a that binds the field board 70 to the rafter member 78 penetrates the short wall 781 and enters the inside of the rafter member 78. Inside the rafter member 78, a punching burr 784 is formed so as to surround the screw 78a. The punching burr 784 is entangled with the screw 78a and hinders the pulling out of the screw 78a.

The rafter member 78 is provided with a crimped portion 785 in which both side portions of the metal plate (material metal plate) constituting the rafter member 78 are crimped. In other words, in the rafter member 78 of the present embodiment, both side portions of the material metal plate are not joined by welding. When a surface-treated metal plate is used as the material metal plate, if both sides of the material metal plate are welded, the surface treatment of the joint portion is removed. When the surface treatment is removed, corrosion is likely to occur from the joint. In addition, it will be necessary to repair the surface treatment of the joint. By joining both sides of the material metal plate by caulking, it is possible to avoid the occurrence of such a problem. The crimped portion 785 of the present embodiment is composed of a goby-folded portion in which both side portions of the material metal plate are goby-folded.

<About flat roofing materials>
Next, FIG. 8 is a perspective view showing the flat roofing material 8 of FIG. 4, FIG. 9 is a cross-sectional view of the flat roofing material 8 along the line IX-IX of FIG. It is a perspective view which shows 81. As shown in FIG. 8, the flat roofing material 8 has a roofing material main body 80 and a plurality of hangers 81.

As shown in FIG. 9, the roofing material main body 80 of the present embodiment includes a front base material 800 made of a metal plate, a back base material 801 arranged on the back side of the front base material 800, and a front base material 800. It is composed of a metal roofing material having a core material 802 filled between the backing material 801 and the backing material 801.

The front base material 800 is a box-shaped metal plate having an opening on the back side, and is a member that appears on the outer surface of the roof when the flat roof material 8 is placed on the base material 7. The metal plate used as the material of the table base material 800 includes hot-dip galvanized steel plate, hot-dip aluminum-zinc alloy plated steel plate, hot-dip zinc-aluminum-magnesium alloy plated steel plate, hot-dip aluminum-plated steel plate, hot-dip galvanized stainless steel plate, and hot-dip aluminum-. Zinc alloy plated stainless steel plate, hot dip zinc-aluminum-magnesium alloy plated stainless steel plate, hot dip aluminum plated stainless steel plate, stainless steel plate, Al plate, Ti plate, painted hot dip galvanized steel plate, painted hot dip aluminum-zinc alloy plated steel plate, painted hot dip zinc -Aluminum-magnesium alloy plated steel plate, painted aluminum plated steel plate, painted hot dip galvanized stainless steel plate, painted hot dip galvanized stainless steel plate, painted hot dip galvanized steel plate, painted hot dip galvanized stainless steel plate, painted hot dip galvanized stainless steel plate, painted A stainless steel plate, a coated Al plate, and a coated Ti plate can be used.

The thickness of the metal plate is preferably 0.5 mm or less. As the thickness of the metal plate increases, the strength of the flat roofing material 8 increases while the weight increases. By setting the thickness of the metal plate to 0.5 mm or less, it is possible to prevent the weight of the flat roofing material 8 from becoming too large. The thickness of the metal plate is preferably 0.27 mm or more. By setting the thickness of the metal plate to 0.27 mm or more, the strength required for the flat roofing material 8 can be secured, and sufficient wind pressure resistance can be obtained. The wind pressure resistance is the performance that the flat roofing material 8 can withstand a strong wind without buckling.

The back base material 801 is arranged on the back side of the front base material 800 so as to close the opening on the back side of the front base material 800. As the backing base material 801, 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 backing material 801 it is possible to avoid an increase in the weight of the flat roofing material 8.

The core material 802 is made of, for example, a foamed resin, and is filled between the front base material 800 and the back base material 801. By filling the core material 802 between the front base material 800 and the back base material 801, the inside of the front base material 800 is more than the mode in which the backing material such as a resin sheet is attached to the back side of the front base material 800. The core material 802 can be firmly adhered to the core material 802, and the performance required for the flat roof material 8 such as rain noise and heat insulation can be improved. As the core material 802, a preformed plate-shaped heat insulating foam may be used.

The material of the core material 802 is not particularly limited, and urethane, phenol, nurate resin and the like can be used. However, it is desirable to use non-combustible certified materials for roofing materials. The non-combustible material certification test is a heat generation test based on the ISO5660-1 cone calorimeter test method. When the foamed resin to be the core material 802 is urethane or the like having a large calorific value, the thickness of the table base material 800 as a whole can be reduced, or the foamed resin can contain inorganic foamed particles.

The height of the internal space of the surface base material 800 filled with the core material 802 is preferably 4 mm or more and 8 mm or less. By setting the height of the internal space to 4 mm or more, the strength of the surface base material 800 can be sufficiently increased, and the wind pressure resistance can be improved. The heat insulating property is also good when it is 4 mm or more.

<About the side cover process>
In the side covering step (step S4), after covering the butt portion with the width direction extending portion 71a and / or the depth direction extending portion 71b (first waterproof sheet 71), as shown in FIG. The side cover material 4 is superposed on the base material 7 of the first to fourth roof units 21 to 24 so as to cover the side exposed areas 211 of the fourth roof units 21 to 24. At this time, the side cover material main body 40 of the side cover material 4 is formed on a pair of flat roofing materials 8 (for example, the flat roofing materials 8 of the first and second roof units 21 and 22) that are separated from each other with respect to the eaves direction 5 of the building. Can be stacked. Further, the other end 40a of the side cover material main body 40 is inserted under the flat roof material 8 located on the ridge side of the pair of flat roof materials 8 on which the side cover material main bodies 40 are overlapped.

Further, the core material 42 is inserted between the pair of flat roofing materials 8 on which the side cover material main body 40 is overlapped.

In such a roof construction method and roof structure 1, since the butt portion between the roof units is covered with the waterproof sheet, it is possible to shorten the time required for roof construction while suppressing the decrease in water stopping property.

Further, since the width direction extension portion 71a and / or the depth direction extension portion 71b (first waterproof sheet 71) extends from any one of the pair of adjacent roof units 2, the roof units 2 are adjacent to each other. The butt portions can be covered with the width direction extension portion 71a and / or the depth direction extension portion 71b (first tarpaulin 71) according to the arrangement. Compared with the mode in which the waterproof sheet is prepared as a separate member, it is possible to more reliably suppress the decrease in water stopping property and further shorten the time required for roof construction.

Further, since the depth direction extending portion 71b (first waterproof sheet 71) is overlapped with the end exposed area 210 straddling the butt portion, the time required for roof construction can be further shortened. That is, if the flat roof material 8 is arranged up to the exposed end region 210, it takes time to insert the first waterproof sheet 71 under the flat roof material 8, but by adopting the configuration of the present embodiment, It is possible to avoid the occurrence of such trouble.

Furthermore, since the end cover material 3 is inserted under the flat roof material 8 of the roof unit 2 on the ridge side and overlapped with the flat roof material 8 of the roof unit 2 on the eave side, the end cover material 3 stands out. This can be avoided and the end exposed area 210 can be covered more reliably. In other words, the end cover material 3 can be mixed in the plurality of flat roofing materials 8 arranged.

Further, since the end cover material 3 is the flat roof material 8, it is possible to more reliably prevent the end cover material 3 from being conspicuous.

Further, since the extending portion 71a (first waterproof sheet 71) in the width direction is overlapped with the side exposed area 211 straddling the butt portion, the time required for roof construction can be further shortened. That is, if the flat roofing material 8 is arranged up to the side exposed area 211, it takes time to insert the first waterproof sheet 71 under the flat roofing material 8, but by adopting the configuration of the present embodiment, It is possible to avoid the occurrence of such trouble.

Furthermore, since each roof unit 2 is arranged so that the side exposed areas 211 of each roof unit 2 are adjacent to each other with respect to the eaves direction 5 of the building, the end portion of the flat roof material 8 of each roof unit 2 is damaged during transportation and installation. The risk of this can be reduced. Further, when a defect occurs in the first waterproof sheet 71, repairs such as attaching a waterproof tape to the butt portion between the roof units 2 can be performed.

Further, the side cover material main body 40 is superposed on the pair of flat roofing materials 8 separated from each other with respect to the eaves direction 5 of the building, and the side portion is under the flat roofing material 8 located on the ridge side of the pair of flat roofing materials 8. Since the other end 40a of the cover material main body 40 is inserted and the engaging portion 41 is arranged so as to be engaged with the eaves side ends of the pair of flat roofing materials 8, it is possible to prevent the side cover material 4 from being conspicuous. While doing so, the side exposed area 211 of the roof unit 2 can be covered more reliably. In other words, the side cover material 4 can be mixed in the plurality of flat roofing materials 8 arranged.

Further, since the side cover material 4 further has a core material 42 that is arranged on the back surface side of the side cover material main body 40 and is inserted between the pair of flat roofing materials 8, the side cover material The sound insulation performance of 4 can be improved, and the treading performance of the side cover material 4 can be improved.

Furthermore, since the flat roofing material 8 is a metal roofing material having a front base material 800, a back base material 801 and a core material 802, it is possible to avoid an increase in the weight of the roof. Further, since the metal roofing material allows bending, it is possible to reduce the risk of damage to the flat roofing material 8 when the end cover material 3 is inserted under the flat roofing material 8 of the roof unit 2 on the ridge side. Further, when the side cover material main body 40 is made of a metal plate, the difference between the surfaces of the side cover material main body 40 and the flat roof material 8 can be reduced and the design can be improved.

In the embodiment, the first waterproof sheet 71 is extended from one of the pair of adjacent roof units 2, but the butt portion between the roof units is formed by the waterproof sheet prepared as a separate member. You may cover it.

Further, although it has been described that the roof unit 2 is provided with the end exposed area 210 or the side exposed area 211, the entire surface of the base material of the roof unit is covered with the flat roof material, and the end exposed area and the side exposed area are exposed. The area may not be provided.

Further, although the flat roofing material 8 has been described as a metal roofing material, a flat roofing material of a flat roof slate such as a color vest may be used.
