<About rafters>
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, the sheathing board 70 of FIG. 3 is also shown in FIG. The rafter member 78 of this embodiment is configured by a rectangular metal pipe. Also, the rafter member 78 of this embodiment has a closed cross-section. More specifically, the rafter member 78 of the present embodiment is composed of a square metal pipe having a rectangular cross section and having long walls 780 and short walls 781 . A long wall 780 and a short wall 781 form the walls of the rafter member 78 . As shown in FIG. 7, the rafter member 78 of the present embodiment is adapted such that the long wall 780 extends in the vertical direction and the sheathing board 70 of FIG. 3 is placed on the short wall 781 . However, the cross-sectional shape of the rectangular metal tube is arbitrary, and may be other shapes such as square or trapezoid. Since the rafter member 78 is a square metal pipe having a closed cross section, the strength can be secured even if the rafter member 78 is thinned and lightened, and workability can be improved. Further, if the rafter member 78 is made of wood, the rafter member 78 may be bent, which may interfere with the arrangement of the roof units 21-24. Such fears can be reduced by forming the rafter members 78 from rectangular metal pipes.

As a raw material for the rectangular 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, 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 ribs 783 on the short walls 781, the rigidity of the rafter members 78 against external forces applied to the rafter members 78 along the direction perpendicular to the longitudinal direction of the rafter members 78 can be improved. The rib 783 of this embodiment has a plurality of recesses spaced apart in the width direction of the short wall 781 . The plurality of recesses of this embodiment form first and second groups of recesses 7831 and 7832 . The first and second groups of recesses 7831 and 7832 are arranged on both sides of a flat plate portion 7833 formed in the central portion of the short wall 781 in the width direction. In addition, the rib 783 may have a plurality of protrusions spaced apart in the width direction of the short wall 781 .

As shown in FIG. 7 , the screws 78 a that fasten the sheathing board 70 to the rafter member 78 pass through the short wall 781 and enter the inside of the rafter member 78 . A punching burr 784 is formed inside the rafter member 78 so as to surround the screw 78a. The punching burr 784 entangles the screw 78a and prevents the screw 78a from being pulled out.

The rafter member 78 is provided with crimped portions 785 in which both side portions of the metal plate (material metal plate) forming the rafter member 78 are crimped. In other words, in the rafter member 78 of the present embodiment, both sides 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 is removed. When the surface treatment is removed, the joints are more susceptible to corrosion. In addition, it becomes necessary to repair the surface of the joint. Such a problem can be avoided by joining both sides of the material metal plate by caulking. The crimped portion 785 of the present embodiment is configured by seam-folded portions in which both side portions of the material metal plate are seam-folded.

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

As shown in FIG. 9, the roof material body 80 of the present embodiment includes a front substrate 800 made of a metal plate, a back substrate 801 arranged on the back side of the front substrate 800, and a front substrate 800. It is composed of a metal roofing material having a core material 802 filled between it and a 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 . As the metal plate that is the material of the front substrate 800, 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, 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 sheet, Painted aluminum plated steel plate, Painted hot-dip galvanized stainless steel plate, Painted hot-dip aluminum-zinc alloy plated stainless steel plate, Painted hot-dip zinc-aluminum-magnesium alloy plated stainless steel plate, Painted hot-dip aluminized stainless steel plate, Painted A stainless steel plate, a coated Al plate, or 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 roof material 8 increases, but the weight also 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 roof material 8 from becoming too large. In addition, it is preferable that the thickness of the metal plate is 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 roof material 8 can be secured, and sufficient wind pressure resistance can be obtained. The wind pressure resistance is the ability of the flat roof material 8 to withstand strong winds 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 back 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 back base material 801, an increase in the weight of the flat roof material 8 can be avoided.

The core material 802 is made of foamed resin or the like, and is filled between the front base material 800 and the back base material 801 . By filling the space between the front base material 800 and the back base material 801 with the core material 802, the inside of the front base material 800 can be more easily absorbed than the mode in which a 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, 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 insulating foam may be used.

The material of the core material 802 is not particularly limited, and urethane, phenol, nurate resin, or the like can be used. However, it is desirable to use certified noncombustible materials for roofing materials. As a noncombustible material certification test, an exothermic test based on the ISO5660-1 cone calorimeter test method is carried out. If the foamed resin used as the core material 802 is urethane or the like that generates a large amount of heat, the overall thickness of the front substrate 800 can be reduced, or inorganic foamed particles can be included in the foamed resin.

The height of the internal space of the front substrate 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 front substrate 800 can be sufficiently increased, and the wind pressure resistance can be improved. The heat insulation property is also improved when the thickness is 4 mm or more. In addition, by setting the height of the internal space to 8 mm or less, the organic mass of the core material 802 is prevented from becoming too large, so that the noncombustible material certification can be obtained more reliably.

Returning to FIG. 8 , on the surface of the front base material 800 , there are positions on both sides of the flat roof material 8 in the width direction 8 w and on the eaves side when the flat roof material 8 is placed on the base material 7 . An input display section 803 is provided at the place. The driving display portion 803 is a structure for indicating the position at which a tightening member such as a nail or a screw is driven into the flat roof material 8 . The input display portion 803 of the present embodiment is configured by a concave portion that is circular in plan view.

As shown in FIG. 18, the roof construction method of the present embodiment includes a unit placement step (step S1), a butt cover step (step S2), an end cover step (step S3), and a side cover step (step S4) is included.

<Regarding the unit placement process>
In the unit arrangement step (step S1), as shown in FIG. 19, a plurality of roof units 2 are arranged on the upper part of the building so as to be adjacent to each other.

Specifically, after placing the first roof unit 21 on the upper part of the building, the second roof unit 22 is placed on the upper part of the building so as to be adjacent to the first roof unit 21 with respect to the eaves direction 5 of the building. These first and second roof units 21 , 22 are arranged such that their side exposed areas 211 are adjacent to each other with respect to the eaves direction 5 .

Also, at this time, a hanger may be attached to the side exposed region 211 of the first roof unit 21 . By attaching slings to the struts 72 and the exposed side regions 211, the first roof unit 21 can be hoisted with good balance. When placing the second roof unit 22 on top of the building, slings can be attached to the exposed side areas 211 on both sides of the second roof unit 22 . The same applies to the third and fourth roof units 23,24.

Also, after the first roof unit 21 is arranged on the upper part of the building, the third roof unit 23 is arranged on the upper part of the building so as to be adjacent to the first roof unit 21 with respect to the eaves ridge direction 6 of the building. The third roof unit 23 is positioned such that the eaves edge of the third roof unit 23 is adjacent to the exposed edge area 210 of the first roof unit 21 .

Furthermore, after placing the second and third roof units 22, 23 on the upper part of the building, they are arranged so as to be adjacent to the third roof unit 23 in the eaves direction 5 and to be adjacent to the second roof unit 22 in the eaves direction 6. , a fourth roof unit 24 is placed on top of the building. The third and fourth roof units 23 , 24 are arranged such that their side exposed areas 211 adjoin each other with respect to the eaves direction 5 .

<Regarding the butt cover process>
In the butt covering step (step S2), the butt portions between the roof units 2 are covered with the first waterproof sheet 71 as shown in FIG. As described above, the second to fourth roof units 22 to 24 of the present embodiment have the widthwise extending portion 71a and/or the depthwise extending portion 71b extending from the roof unit main body. For this reason, in the roof construction method of the present embodiment, the abutting portions of the roof units 2 are arranged as the widthwise extending portion 71a and/or the depthwise extending portion 71b in accordance with the arrangement of the roof units 2 so as to be adjacent to each other. Cover with (first waterproof sheet 71).

Specifically, when the second roof unit 22 is arranged so as to be adjacent to the first roof unit 21, the widthwise extending portion 71a of the second roof unit 22 is positioned between the first and second roof units 21 and 22. By overlapping the side exposed region 211 of the first roof unit 21 straddling the abutting portion of the second roof unit 22, the abutting portion between the first and second roof units 21 and 22 becomes the width direction extending portion 71a of the second roof unit 22. covered by

Further, when the third roof unit 23 is arranged so as to be adjacent to the first roof unit 21, the depth direction extending portion 71b of the third roof unit 23 is the abutting portion between the first and third roof units 21 and 23. By overlapping the end exposed region 210 of the first roof unit 21 straddling the ridge, the abutting portion between the first and third roof units 21 and 23 is covered with the depth direction extending portion 71b of the third roof unit 23. .

Furthermore, when arranging the fourth roof unit 24 so as to be adjacent to the second roof unit 22, the depth direction extending portion 71b of the fourth roof unit 24 is the abutment portion between the second and fourth roof units 22, 24 By overlapping the end exposed region 210 of the second roof unit 22 straddling, the abutting portion between the second and fourth roof units 22 and 24 is covered with the depth direction extending portion 71b of the fourth roof unit 24. . Similarly, when arranging the fourth roof unit 24 so as to be adjacent to the third roof unit 23, the width direction extension 71a of the fourth roof unit 24 will By overlapping the side exposed region 211 of the third roof unit 23 across the portion, the abutting portion between the third and fourth roof units 23 and 24 is covered by the width direction extending portion 71a of the fourth roof unit 24. will be

<Regarding the edge cover process>
In the end covering step (step S3), after covering the butted portion with the widthwise extending portion 71a and/or the depthwise extending portion 71b (first waterproof sheet 71), as shown in FIGS. The end covering material 3 is overlaid on the base material 7 of the first and second roof units 21,22 so as to cover the exposed end areas 210 of the first and second roof units 21,22. The end covering material 3 is inserted under the flat roof material 8 of the third and fourth roof units 23, 24 (roof units on the eaves side) and the first and second roof units 21, 22 (roof units on the eaves side). roof unit) is superimposed on the flat roof material 8. As described above, the flat roof material 8 as the end covering material 3 is wider than the flat roof material 8 included in the roof unit 2 . A pair of end coverings 3 covering the end exposed areas 210 of the first and second roof units 21, 22 respectively are adjacent to each other with respect to the eaves direction 5 of the building. The eaves-side end of the end cover member 3 is engaged with the second engaging portion 812 provided on the hanger 81 of the flat roof member 8 of the first and second roof units 21 and 22 . Also, the end cover material 3 can be fastened to the base material 7 of the first to fourth roof units 21 to 24 by means of fastening members 9 such as screws or nails. A binding member 9 is preferably driven into the end of the end covering 3 so that the binding member 9 driven into the end covering 3 can be concealed by the side covering 4 .

<About the side cover process>
In the side covering step (step S4), after covering the butted portion with the widthwise extending portion 71a and/or the depthwise extending portion 71b (first waterproof sheet 71), as shown in FIG. The side covering material 4 is superimposed on the base material 7 of the first to fourth roof units 21-24 so as to cover the side exposed areas 211 of the fourth roof units 21-24. At this time, the side cover member body 40 of the side cover member 4 is attached to a pair of flat roof members 8 (for example, the flat plate roof members 8 of the first and second roof units 21 and 22) separated in the eaves direction 5 of the building. be superimposed. Further, the other end 40a of the side cover material main body 40 is inserted under the flat plate roof material 8 positioned closer to the ridge than the pair of flat plate roof materials 8 on which the side cover material main bodies 40 are superimposed. Further, the engaging portion 41 is engaged with the eaves side end portion of the pair of flat roof members 8 on which the side cover member main bodies 40 are superimposed. Further, a core material 42 is inserted between the pair of flat roof materials 8 on which the side cover material bodies 40 are superimposed.

In such a roof construction method and roof structure 1, the abutting portions between the roof units are covered with the waterproof sheet, so that it is possible to shorten the time required for roof construction while suppressing the deterioration of the waterproofness.

In addition, since the widthwise extending portion 71a and/or the depthwise extending portion 71b (first waterproof sheet 71) extends from one of the pair of adjacent roof units 2, the roof units 2 are adjacent to each other. The abutting portions can be covered with the widthwise extending portion 71a and/or the depthwise extending portion 71b (the first waterproof sheet 71). Compared to a mode in which a waterproof sheet is prepared as a separate member, it is possible to more reliably suppress the deterioration of the waterproofness and further shorten the time required for roof construction.

Furthermore, since the depth-direction extending portion 71b (the first waterproof sheet 71) is overlapped with the end exposed region 210 across the butted portion, the time required for roof construction can be further shortened. That is, if the flat roof material 8 were arranged up to the end exposed region 210, it would be troublesome to insert the first waterproof sheet 71 under the flat roof material 8, but by adopting the configuration of the present embodiment, Such time and effort can be avoided.

Furthermore, since the end covering 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 eaves side, the end covering material 3 stands out. can be avoided, and the exposed end region 210 can be covered more reliably. In other words, the end cover material 3 can be mixed into the plurality of flat roof materials 8 arranged.

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

Furthermore, since the widthwise extending portion 71a (first waterproof sheet 71) is overlapped with the side exposed region 211 across the butted portion, the time required for roof construction can be further shortened. That is, if the flat roof material 8 were arranged up to the side exposed region 211, it would be troublesome to insert the first waterproof sheet 71 under the flat roof material 8, but by adopting the configuration of the present embodiment, Such time and effort can be avoided.

Furthermore, since each roof unit 2 is arranged so that the side exposed areas 211 are adjacent to each other with respect to the eaves direction 5 of the building, the ends of the flat roof materials 8 of each roof unit 2 are damaged during transportation and installation. It is possible to reduce the risk of Further, when a problem occurs in the first waterproof sheet 71, it is possible to perform repair such as attaching a waterproof tape to the butted portion between the roof units 2. FIG.

In addition, the side cover material main body 40 is superimposed on a pair of flat plate roof members 8 spaced apart in the eaves direction 5 of the building, and the side cover member 40 is placed under the flat plate roof member 8 positioned closer to the ridge than the pair of flat plate roof members 8 . The other end 40a of the cover material main body 40 is inserted, and the engaging part 41 is arranged so as to be engaged with the eaves-side ends of the pair of flat roof materials 8, so that the side cover material 4 is prevented from being conspicuous. However, the side exposed area 211 of the roof unit 2 can be covered more reliably. In other words, the side cover member 4 can be tucked into the plurality of flat roof members 8 arranged.

Furthermore, since the side cover member 4 further has a core member 42 arranged on the back side of the side cover member main body 40 and inserted between the pair of flat roof members 8, the side cover member 4 can be improved, and the trampling performance of the side cover member 4 can be improved.

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

In the embodiment, the first waterproof sheet 71 extends from either one of the pair of adjacent roof units 2, but a waterproof sheet prepared as a separate member separates the abutting portions between the roof units. You can cover it.

Also, although the roof unit 2 has been described as having the end exposed region 210 or the side exposed region 211, the entire surface of the base material of the roof unit is covered with the flat roof material, and the end exposed region and the side exposed region are covered. No region may be provided.

Further, although the flat roofing material 8 has been described as being a metal roofing material, flat roofing slate flat roofing material may also be used, for example, a collar vest.

The portion 301 is inserted under the flat roof member 8 of the roof unit 2 on the ridge side and engages with the flat roof member 8 of the roof unit 2 on the ridge side, and the other end of the base plate portion 300 is extended to the back side of the base plate portion 300 . Since the lower folded portion 302 folded back is inserted under the end cover material 3 and engages with the end cover material 3, corrosion of the binding member 9 can be suppressed and the binding member can be used for a long time. It is possible to prevent the cover 30 from coming off.

Note that the binding member cover 30 of the present embodiment may be used to cover and hide the binding member driven into any member other than the end cover member 3 . The binding member cover 30 is driven into the first member when the arbitrary member into which the binding member is driven is called the first member and the member into which one end of the first member is inserted is called the second member. A binding member cover for hiding the binding member may be provided. The base portion 300 may be overlaid on a fastening member that is driven into the first member. The upper cuff 301 can be inserted under and engage the second member. A lower cuff 302 may be inserted under and engaged with the first member. If the first and second members do not have a member that interferes with the binding member cover 30, such as the hanger 81, the upper notch 303 and the lower notch 304 may be omitted.
