  The roof sheet material proposed in these publications is a roof sheet material joined to the roof assembly so that the roof sheet material has a thatched appearance from the roof ridge side to the eaves side. It has a spear-like part and a structure for closing it. By doing this, it has the excellent advantage of preventing rainwater from entering the rain gutter-like part and preventing rainwater intrusion, but further simplification of the shape and associated cost reduction and further construction There is a demand for simplification.

  In order to achieve at least a part of the problems described above, the present invention can be implemented as the following forms.

  (1) According to one form of this invention, a roofing board material is provided. The roof plate material is a roof plate material that is rolled adjacent to the roof assembly along the roof width direction, and is a long and predetermined width plate material that extends from the roof ridge side to the eaves side. A first roof plate member joined to the set, and a long plate member extending from the roof ridge side to the eaves side and wider than the first roof plate member, and above the roof set, on the ridge side of the roof And a second roofing sheet material that exhibits a thatched appearance from the eave side to the eaves side, wherein the first roofing sheet material is bent at one end side in the width direction, and from the one end part to the upper side of the roof assembly. An end first plate member that extends, and an end second plate member that is bent on the side of the other end in the width direction and extends from the other end to the upper side of the roof assembly, and the second roof The plate material is bent from the end second plate material portion on the one end portion side in the width direction, and then the other end portion in the width direction. And the second roof plate material is connected to the second roof plate material, and has an end third plate material portion extending from the other end portion of the second roof plate material to the roof assembly side, and the end first plate material portion is Extending from the one end to the vicinity of the lower surface of the second roof plate of the adjacent roof plate covering the first roof plate and the end first plate, and the second roof plate is the end third In the state where the end third plate member is joined to or close to the end second plate member of the roof plate adjacent on the plate member side, the roof plate member adjacent on the end third plate member side. Covering the first roof plate material and the end first plate material portion, exhibiting the appearance of the appearance, the end third plate material portion of the roof plate material adjacent on the side of the end third plate material portion. One roof plate extends from the other end to the top surface.

  The roof sheet material of the above-mentioned form is a second roof sheet material that is rolled so as to be adjacent to each other along the width direction of the roof, and has a thatched appearance from the roof ridge side to the eaves side. The plate material and the end first plate material portion are covered. In addition, this second roof sheet material has a roared appearance in a state where the end third plate material part is joined or close to the end second sheet material part of the adjacent roof sheet material. When it rains, most of the rainwater flows down from the ridge side to the eaves side with the upper surface of the second roof sheet material along the roof gradient. And the roof board | plate material of the said form is the edge part 2nd board | plate part part and edge part 3rd board | plate part part of an adjacent roof board | plate material in the rainwater infiltration location to the 1st roof board | plate material side covered with the 2nd roof board | plate material. It is limited to the gap of. Since this gap is narrowed by joining or proximity of the end third plate member to the end second plate member of the adjacent roof plate, the roof plate of the above form is the first roof plate joined to the roof assembly. Limit the intrusion of rainwater on the side of In this way, in addition to the restriction, the extension of the infiltrated rain water along the upper surface of the first roof plate material joined to the roof assembly is also restricted by extending the end third plate material portion to the upper surface of the first roof plate material of the adjacent roof plate material. In addition, the roof sheet material of the above form functions as a rain gutter having the width of the first roof sheet material by using the first roof sheet material itself and the end first plate material part and the end second plate material part at both ends thereof. Therefore, rainwater that has entered the first roof plate material side through the gap flows down along the roof slope along the upper surface of the first roof plate material, and enters the roof assembly side beyond the end first plate material portion. It becomes difficult to do. As a result, according to the roof board material of the above-mentioned form, it is possible to prevent intrusion of rainwater.

  In the roof plate material of the above form, as described above, in order to prevent rainwater intrusion, the end first plate member and the second end plate member at one end and the other end in the width direction of the first roof plate. The shape of the second roof plate material from the end second plate member and the end third plate member at the other end of the second roof plate member can be bent. Manufacturing cost and construction cost can be reduced. Moreover, in the roof board | plate material of the said form, an edge part 3rd board | plate part is joined or adjoined to the edge 2nd board | plate material part of an adjacent roof board | plate material in the connection location of an adjacent roof board member, and it is in 2nd roof board | plate material. Since it is only necessary to arrange in the roof width direction in the roof assembly so as to cover the first roof plate material of the adjacent roof plate materials, it is possible to further simplify the rolling work and reduce the construction cost associated therewith. In addition, the collection of the roof plate material after the construction becomes simple, and the roof plate material after the collection can be reused as it is. Furthermore, workability is further enhanced without requiring on-site processing such as bending at the roofing site.

  (2) In the roof sheet material of the above-described form, the end first plate material part can extend from the one end part until it contacts the lower surface of the lower surface of the second roof sheet material of the adjacent roof sheet material. If it carries out like this, the rainwater which infiltrated into the 1st roof board | plate side from the gap | interval of the edge part 2nd board | plate material part and edge part 3rd board | plate part of an adjacent roof board | plate material will try to overflow over an edge part 1st board | plate material part. However, such overflow can be made difficult to occur due to the contact between the lower surface of the lower surface of the second roof plate member and the end first plate member portion, so that rainwater intrusion to the roof assembly side can be avoided.

  (3) In the roof plate material of the above-described form, the end first plate member portion, the end second plate member portion, and the end third plate member portion extend perpendicularly to the upper surface of the roof assembly, and The second roof sheet material may be horizontal with respect to the upper surface of the roof set above the roof set. By doing so, the shape is further simplified, so that the mold in the case of employing press working can be simplified, and the manufacturing cost can be further reduced.

  (4) In the roof plate material of the above-described form, the first shaft material enters the first shaft material having a shorter overall length than the difference in width between the first roof plate material and the second roof plate material, and one end side. A second shaft member having an annular body and a shaft portion extending from the annular body, wherein the first shaft material extends from the end second plate member toward the end third plate member. The second shaft member is fixed to the end second plate member, and the second shaft member has a length extending from the first shaft member through the roof assembly, and a distal end side of the shaft portion is a male screw. You can If it carries out like this, the roof board | plate material after rolling can be fixed to a roof set by screwing a nut in the external thread of the 2nd shaft material which penetrated the roof set. And since the 2nd shaft material can be made not to protrude from the 1st roof board material by rotating the 2nd shaft material around the 1st shaft material, the operation | work at the time of conveyance of a roof board material or a storage is carried out. It becomes simple.

  (5) In the roof plate material of the above-described form, the end first plate member portion, the end second plate member portion, and the end third plate member portion extend vertically at a height of 50 to 150 mm, and The total width of the first roof plate member and the second roof plate member from the first plate member portion to the end third plate member portion is 450 to 1200 mm, and the second roof plate member is the first roof. It can be made 50-100 mm wider than the plate. If it carries out like this, it can prevent more reliably that rainwater permeates into the roof assembly side exceeding an edge part 1st board | plate part part by ensuring the height of an edge part 1st board | plate material part. Moreover, the first roof plate material itself can be secured to a certain extent even though the width is narrower than that of the second roof plate material. Therefore, the first roof plate material itself is composed of an end first plate material portion and an end second plate material at both ends thereof. Since the rain gutter function can be wide at the part, rain water intrusion to the roof assembly side beyond the end first plate member part can be made more difficult, and the effectiveness of rain water infiltration prevention can be ensured.

  In addition, this invention can be implement | achieved with various forms, for example, can be implement | achieved in aspects, such as a residence and a roof which have a roof-plate material.

The roof covering materials 110L and 110R are hung from the purlin MB in the roof set YH to the eaves side, that is, the roof is hung from the roof ridge side to the eave side, and the roofing appearance is made. The ridge wrap 120 covers the roof covering materials 110L and 110R over the width of the roof, and forms a roof ridge appearance. The roof set YH hangs the rafters N over the NB from the purlin MB, and supports the rafters N of the purlin MB with pillars using a shed, a hut, a wife, or the like. In this case, some rafters N have a rectangular through hole NH into which a second shaft member 322 having a male screw for fixing a roof plate member 310 to be described later is inserted.

  FIG. 2 is an explanatory view showing a state in which the roof is longitudinally rolled by the roof roofing material 110L composed of a plurality of roofing sheet materials 310, FIG. 3 is a schematic perspective view showing the roofing state together with the detailed configuration of the roofing sheet material 310, FIG. These are explanatory drawings showing the configuration of the fixing mechanism 320 involved in fixing the roof plate material 310 to the roof set YH and the state of its assembly. The roof covering material 110R is the same as the roof covering material 110L, and the facing side is different in FIG. 1, but may be directed to the same side.

  As shown in these drawings, the roof plate material 310 is a first roof plate material 312 formed of a long and predetermined width metal steel plate (for example, a steel plate made of titanium or stainless steel having a plate thickness of about 5 mm), and A second roof plate material 314 formed from the above-described metal steel plate wider than the first roof plate material 312, an end first plate material portion 313 a, an end second plate material portion 313 b, and an end third It has the board | plate material part 313c and the fixing mechanism 320. FIG. The first roof sheet material 312 extends from the roof ridge side to the eaves side, is joined to the roof set YH, and is inclined at the roof gradient θ in the roof set YH. The second roof plate member 314 is supported by an end second plate member portion 313b and an end third plate member portion 313c, which will be described later, and is positioned above the roof set YH and extends from the roof ridge side to the eaves side. Above the roof set YH, a roofed appearance is applied from the roof ridge side to the eaves side, and the roof set YH is inclined at a roof gradient θ.

  The end first plate member 313a is bent substantially vertically on one end side in the width direction of the first roof plate member 312, that is, on the right end side in the drawing, and is connected to the first roof plate member 312 so that the upper side of the roof set YH. Extend to. The end second plate member 313b is a plate connecting the first roof plate 312 and the second roof plate 314, and is substantially vertical on the other end side in the width direction of the first roof plate 312, that is, on the left end side in the drawing. And is connected to the first roofing sheet material 312, extends to the upper side of the roof set YH, and is connected to the second roofing sheet material 314. In this case, the second roof plate member 314 is bent substantially vertically from the upper end of the end second plate member 313b and extends horizontally, and is connected to the end second plate member 313b. The end third plate member 313c is bent substantially vertically on the other end side in the width direction of the second roof plate member 314, that is, on the left end side in the drawing, and is connected to the second roof plate member 314, on the roof assembly YH side. Extend. From such a bending state, the second roof plate member 314 is supported by the end second plate member portion 313b and the end third plate member portion 313c at both ends thereof, and is positioned above the roof assembly YH in parallel with the first roof plate member 312. .

  As shown in detail in FIG. 4, the fixing mechanism 320 includes a first shaft member 321 and a second shaft member 322. The first shaft member 321 has a total length that is shorter than the difference in width between the first roof plate member 312 and the second roof plate member 314, and includes a shaft 321a extending from the end second plate member 313b and a base 321b. . The first shaft member 321 is spot welded to the end first plate member 313a at the distal end surface of the shaft 321a. Spot welding is performed from the outer surface side of the end second plate member 313b, and the welding trace Sw does not protrude from the outer surface. By such welding, the first shaft member 321 extends from the end second plate member 313b toward the end third plate member 313c and is fixed to the end second plate member 313b. The base 321b has a larger diameter than the shaft 321a and has a two-sided width portion. The second shaft member 322 includes an annular body 322a, and the distal end side of the shaft portion extending from the annular body is a male screw. The second shaft member 322 includes a through hole 322b in the annular body 322a, and the inner surface of the through hole is a two-plane width portion 322c. Since the interval between the two-surface width portions 322c is larger than the diameter of the shaft 321a of the first shaft member 321, the shaft 321a can be inserted into the through hole 322b. The inner shape of the through-hole 322b including the two-surface width portion 322c is similar to the outer shape of the base portion 321b of the first shaft member 321 and is larger than the outer shape. Therefore, the base portion 321b has a two-surface width portion. It can be fitted into the through-hole 322b including the 322c. The annular body 322a is formed by press punching a circular plate and a through hole 322b having a two-sided width portion 322c, and the second shaft member 322 is a long shaft having a male screw at the tip of the annular body 322a. It is formed by welding.

  In assembling the fixing mechanism 320, the first shaft member 321 is spot-welded to the end second plate member 313b as described above with the shaft shaft 321a inserted into the through hole 322b of the second shaft member 322. The At this time, the first shaft member 321 is spot-welded so that the two-surface width portion of the base portion 321b is substantially parallel to the upper end of the end second plate member portion 313b. The diameter of the second shaft member 322 and the thickness of the annular body 322a are made smaller than the distance from the surface of the end second plate member 313b to the jaw of the base 321b of the first shaft member 321. Therefore, the second shaft member 322 is movable between the end second plate member 313b and the flange portion of the first shaft member 321. When the shaft shaft 321a is positioned in the through hole 322b, A shaft portion having a male screw is extended downward. On the other hand, in the state where the second shaft member 322 is moved to the flange side of the first shaft member 321 and the base portion 321b is fitted into the through hole 322b, the shaft portion having a male screw at the tip is replaced with the base portion 321b. Following the two-surface width portion, it extends so as to be substantially parallel to the upper end of the end second plate member portion 313b. That is, the second shaft member 322 can swing around the shaft shaft 321a of the first shaft member 321.

  The above-described fixing mechanism 320 is installed on the edge second plate member 313b, for example, 3-4 sets at a pitch from the ridge to the eave. After the roof plate member 310 is rolled, the second shaft member 322 is attached to the rafter. The male screw portion is projected below the rafter N of the roof set YH through the N through hole NH. The through hole NH of the rafter N is formed in the rafter N so that the second shaft member 322 in each fixing mechanism 320 can be inserted (see FIG. 1).

  Next, the relationship between the adjacent roof plate members 310 and the extension of the first end plate member portion 313a and the like will be described. FIG. 5 is an explanatory diagram showing the relationship between the first roof plate material 312 and the second roof plate material 314 in the adjacent roof plate materials 310 and the state of extension of the end first plate material portion 313a and the like. As shown in the figure, the plate width 314W of the second roof plate 314 is larger than the plate width 312W of the first roof plate 312. This second roof plate member 314 is adjacent to the end third plate member 313c in the state where the end third plate member 313c is joined or close to the end second plate member 313b of the adjacent roof plate 310 on the end third plate member 313c side. Covering the first roof plate material 312 and the end first plate material portion 313a of the plate material 310, it has a rolled appearance. In this way, the adjacent roof plate members 310 have a gap Rd between the end third plate member portion 313c extending from the second roof plate member 314 and the end second plate member portion 313b of the other roof plate member 310. It is set to about 3 to 10 mm according to the proximity degree of both board | plate materials from substantially zero mm by joining of board | plate materials.

  The end first plate member 313a extends to the vicinity of the lower surface of the second roof plate 314 of the adjacent roof plate 310 that covers the first roof plate 312 and the first end plate member 313a, and forms a clearance C at the tip thereof. To do. In this embodiment, the clearance C is substantially zero, that is, the end first plate member 313a extends until it contacts the lower surface of the second roof plate 314 of the adjacent roof plate 310. The end third plate member 313c extends to the upper surface of the first roof plate 312 of the adjacent roof plate 310 on the end third plate member 313c side. About this edge part 3rd board | plate part 313c, you may extend until it contact | abuts on the upper surface of the 1st roof board | plate material 312, and it is about several mm (preferably 1-3mm) from the upper surface of the 1st roof board | plate material 312 dimensionally. There may be a gap. The second roof plate member 314 connected at one end by the end second plate member portion 313b tends to bend from the bent portion with the end second plate member portion 313b by its own weight, so the end third plate member portion 313c is Even if the gap is dimensional, it contacts the upper surface of the first roof plate material 312.

  The product width 310W of the above-described roof plate material 310 is the sum of the plate material width 312W of the first roof plate material 312 and the plate material width 314W (> 312W) of the second roof plate material 314, and the length of the roof plate material 310 is the length of the roof to be constructed. Manufactured and processed according to the length from the building to the eaves, and then brought into the construction site. Further, the protrusion height 313aH of the end first plate member 313a, the protrusion height 313bH of the end second plate member 313b, and the protrusion height 313cH of the end third plate member 313c are the appearance of the roof and the first roof plate 312. May be determined in consideration of the action as a soot described later. In the present embodiment, it is assumed that the product width 310W of the roof plate material 310 is 450 to 1200 mm (more preferably 600 to 1000 mm), and the plate material width 312W of the first roof plate material 312 is less than half of the product width 310W. The protrusion height was defined as 50 to 150 mm. The plate material width 314W of the second roof plate material 314 is defined to be about 50 to 100 mm wider than the plate material width 312W of the first roof plate material 312 because of the necessity of incorporating the fixing mechanism 320 described above. As shown in FIG. 5, the roof plate material 310 is formed by bending the end first plate material portion 313 a and the end second plate material portion 313 b with respect to the first roof plate material 312, and the end portion with respect to the second roof plate material 314. It can be press-formed from the metal steel plate already described through the bending of the second plate portion 313b and the end third plate portion 313c. The metal steel plate subjected to press forming has a steel plate width 310PW that is equal to the product width 310W of the roof plate member 310, the protruding height 313aH of the end first plate member 313a, and the protruding height of the end second plate member 313b. 313bH, and the width obtained by adding the protruding height 313cH of the end third plate member 313c, the length of the steel plate is the length from the roof ridge to the eave to be constructed, as described above. The length is added.

  In addition, as shown in FIG. 2, the roof roof material 110 </ b> L has a rain finishing plate 340 on the ridge side upper surface of the roof plate material 310. The rain closing board 340 is installed so as to block the ridge-side opening of the roof board material 310 sown by the roof set YH and to rise from the ridge-side end face of the second roof board material 314 that has a thatched appearance. Therefore, the rain finishing board 340 moves the rain water which is going to move against the roof gradient θ on the upper surface of the second roof board material 314 and the first roof board material 312 covered with the second roof board material 314. Dam at the side edge. In addition, the rain finishing board 340 is seamlessly welded to the ridge side end face of the second roof board material 314, and is reinforced with L-shaped steel or the like (not shown) at the joining / fixing portion. The rain finishing board 340 may be welded to the first roof board material 312 on the lower end side thereof.

  The roof 100 according to the present embodiment is to vertically wind the roof as described later with a plurality of roof plate members 310 described above. However, on the wife side of the roof, in order to enhance the appearance of thatching at the wife part, FIG. As shown, it has a left end roof sheet material 310LE and a right end roof sheet material 310RE. The left end roof plate material 310LE has substantially the same shape as the roof plate material 310, and the end third plate material portion 313c is bent and extended from the second roof plate material 314 to the lower side of the rafter N of the roof set YH. The lower end is bent to the wife side. That is, the left end roof plate member 310LE surrounds the rafter N with the end side third plate member portion 313c on the wife side, thereby improving the appearance of the left wife side and preventing rainwater intrusion from the side of the wife portion. ing. FIG. 6 is a schematic perspective view of the right end roof plate member 310RE disposed on the right side of the roof. As shown in the drawing, the right end roof plate member 310RE is disposed on the end portion of the roof roof member 110L that hits the right side, and the end second plate member portion 313b is bent from the second roof plate member 314 to the lower side of the rafter N of the roof set YH. Then, the lower end is bent to the wife side. That is, by surrounding the rafters N on the wife side with the end second plate member 313b, the appearance of the right wife side is improved, and rainwater intrusion from the wife part side is prevented.

  The right end roof plate member 310RE has an indefinite width, whereas the roof plate member 310 and the left end roof plate member 310LE have a fixed width. In other words, since the roof width between the wife of the roof is various, the width of the right end roof plate material 310RE is determined by the roof width, the width of the roof plate material 310 and the left end roof plate material 310LE for each number of roofs. Individually. In addition, since the right end roof board | plate material 310RE is not provided with the 1st roof board | plate material 312, it is provided with the fixing bolt 330 extended below from the bottom face of the 2nd roof board | plate material 314 which it has. The fixing bolt 330 is joined to the bottom surface of the second roof plate member 314 and is liquid-tightly fixed by a technique such as seamless welding. When the roof set YH is rolled by the right end roof plate member 310RE, the fixing bolt 330 penetrates the through hole NH of the rafter N. Then, the male screw part is projected below the rafter N. The fixing bolts 330 are provided on the bottom surface of the second roof sheet material 314 at the eaves side, the ridge side, and the center thereof.

  Next, a description will be given of howling work using the roof covering material 110L using the roof plate material 310 of the present embodiment. In the roof 100 according to the present embodiment, first, the left end roof plate material 310LE is spread over the roof set YH in the case of the rolling operation. At this time, the left end roof plate member 310LE is wound so as to surround the rafter N on the wife side by the end third plate member portion 313c. As shown in FIG. 4, the left end roof plate member 310LE thus rolled extends the second shaft member 322 of the fixing mechanism 320 through the rafter N of the roof set YH and extends downward. Therefore, the wiping operator causes the holding plate Bp and the washer W to be interposed on the lower surface side of the rafter N, and then screws the nut Nt into the male thread portion of the second shaft member 322. Thereby, the left end roof board | plate material 310LE is drawn near to the rafter N side of the roof set YH, and is fixed.

  Next, the roof board material 310 is piled on the left-end roof board material 310LE that has been rolled. At this time, the plowing operator joins the roof plate member 310, which is a counter measure, to join the end second plate member 313b of the left end roof plate member 310LE whose end third plate member 313c has already been rolled. Ask. In the roof 100 of the present embodiment, the end third plate member 313c of the roof plate member 310, which has been countered, is joined to the end second plate member 313b of the left end roof member 310LE that has already been rolled. In other words, the gap Rd shown in FIG. 5 is substantially zero mm. The newly sown roof plate material 310 is also pulled and fixed to the rafter N side of the roof set YH using the fixing mechanism 320, the holding plate Bp, the washer W, and the nut Nt. As shown in FIG. 3, the newly sown roof sheet material 310 has already been fired by the second roof sheet material 314, and the first roof sheet material 310 LE of the left end roof sheet material 310 LE adjacent on the side of the end third plate material part 313 c. The roof plate material 312 and the end first plate material portion 313a are covered, and a roofed appearance from the roof ridge side to the eave side is exhibited. This roofing operation of the roof plate material 310 is repeated for the number of roof plate materials 310 to be rolled.

  Finally, the person who plows piles the right-end roof board material 310RE on the roof board material 310 that has been fired. Even in this case, as shown in FIG. 6, the rowing operator has the right end roof plate member 310RE and the end third plate member portion 313c having the end second plate member portion of the roof plate member 310 that has already been rolled. It asks so that it may join to 313b. And about this right end roof board | plate material 310RE, it fixes to the rafter N with the fixing bolt 330 which it has, and it is sowed so that the rafter N may be surrounded on the wife side by the end 2nd board | plate part 313b which it has.

  The roof roof material 110R uses the above-described roof board material 310, the left end roof board material 310LE, and the right end roof board material 310RE. The roof roof material 110L is different only in the roofing side of the roof, and the configuration is not different from the roof roof material 110L. When the roof set YH is rolled by the roof covering materials 110L and 110R, the ridge wrap 120 is placed so as to close the ridge side of the roof plate material 310 and the right end roof plate material 310RE, and is fixed to the roof set YH by an appropriate fixing means. Is all completed.

  In the roof 100 of the present embodiment described above, the roof plate material 310 is placed side by side on the rafters N during the sowing operation, and the roof plate material 310 that is the counter measure for the sowing is provided in the end of the operation. The third sheet material portion 313c is joined to the second edge sheet material portion 313b of the left edge roof sheet material 310LE that has already been rolled, and the second roof sheet material 314 of the roof sheet material 310 that has been rolled is dealt with. What is necessary is just to cover the 1st roof board | plate material 312 of 310, and the edge part 1st board | plate material part 313a. Therefore, roofing can be performed by simple construction, and roofing construction work and relocation / removal work can be simplified. In addition, coupled with the need for mechanical connection such as screws to join adjacent roof plate members 310, roofing construction work and the like can be further simplified. Further, if the respective roof plate members 310 are placed, the second shaft member 322 of the fixing mechanism 320 protrudes through the rafters N, so that the roof plate member 310 is attached to the roof assembly YH using the second shaft member 322. It can be easily fixed by pulling on the skin.

Here, the rain closing which the roof 100 of this embodiment exhibits is demonstrated.
The rain that has fallen on the roof flows down from the ridge wrap 120 to the left and right of the roof, and reaches the roof covering materials 110L and 110R in areas not covered by the ridge wrap 120. This rain flows down along with the roof slope θ (see FIG. 2) along the roof slope θ (see FIG. 2) in the direction where the upper surface of the first roof plate material 312 is raised together with the rain that has been poured directly onto the roof covering materials 110L and 110R. Rain that has been poured from above almost without strong wind does not flow to the ridge side on the upper surface of the first roof plate material 312 against the roof slope θ. Therefore, by letting rain flow from the ridge wrap 120 to the roof covering materials 110L and 110R, naturally, a suitable rain performance is exhibited on the ridge side against such rain.

  On the other hand, rain that falls with strong winds such as typhoon (strong wind rain) may tend to flow on the ridge side on the upper surface of the first roof plate material 312 against the roof gradient θ. This rain is first blocked by the peripheral portion of the ridge wrap 120 covering the roof plate 310, and only enters the ridge side through the gap at the lower end of the peripheral portion of the ridge wrap. . By the way, the rainwater that has entered the building side in this way receives gravity along the roof gradient θ, and therefore naturally tries to flow down along the roof gradient. For this reason, it is difficult for the intrusion rainwater that has passed through the gap at the lower end of the peripheral portion of the ridge wrap 120 to be stored upstream from the peripheral portion.

  When the wind is extremely strong, the force exerted by the wind on the rainwater increases so that it flows against the roof slope, so the rainwater can flow further toward the ridge after passing through the gap at the lower edge of the peripheral part of the ridge wrap 120. There is also sex. However, the amount of invading rainwater that tends to flow to the ridge side beyond the lower edge of the peripheral portion of the ridge wrap 120 is reduced by the shielding by the lower end of the peripheral portion of the ridge wrap 120 and the action of gravity. Then, the intrusion rain water that has passed over the lower end of the peripheral portion of the ridge wrap 120 is blocked again by the rain closing plate 340 of FIG. 2 protruding from the upper surface of the second roof plate 314 above the lower end of the peripheral portion of the ridge wrap 120.

  Further, even in the case of rain that has flowed down from the ridge wrap 120 to the roof covering materials 110L and 110R, or rain that has been poured directly onto the roof covering materials 110L and 110R, a suitable rain performance is exhibited as follows.

  As shown in FIG. 2 to FIG. 3 and FIG. 6, the roof plate materials 310 adjacent along the width direction of the roof are the second roof plate materials 314 that have a perforated appearance from the roof ridge side to the eaves side. The first roof plate material 312 and the end first plate material portion 313a of the adjacent roof plate material 310 are covered. Moreover, the second roof plate member 314 is joined to the end second plate member portion 313b of the adjacent roof plate member 310 in a state where the end third plate member portion 313c is joined with the gap Rd (see FIG. 5) being substantially zero mm. Exhibits a whispered appearance. Therefore, when it rains on the roof 100 sprinkled with the roof sheet material 310 of the present embodiment, almost all of the rainwater flows down with the upper surface of the second roof sheet material 314 along the roof gradient hanging from the ridge side to the eaves side. And the roof board | plate material 310 of this embodiment is the edge 2nd board | plate material part 313b and edge part in the adjacent roof board | plate material 310 in the rainwater infiltration location to the 1st roof board | plate material 312 side covered with the 2nd roof board | plate material 314. This is limited to the gap Rd with the third plate member 313c. Since the gap Rd is substantially zero mm in the roof plate material 310 of the present embodiment, the roof plate material 310 of the present embodiment has the second end portion of the rainwater that has poured onto the upper surface of the second roof plate material 314. Only rainwater that penetrates the gap Rd between the plate member 313b and the end third plate member 313c enters the first roof plate 312 side. This amount of inundated rainwater is negligible even in heavy rain conditions.

  In addition to this, the roof plate member 310 of the present embodiment has the end third plate member portion 313c abutted against the upper surface of the first roof plate member 312 of the adjacent roof plate member 310, so that the first joined to the roof set YH. The spread of infiltrated rainwater along the upper surface of the roof plate material 312 is also restricted. In addition, as shown in FIG. 5, the roof plate material 310 of the present embodiment includes a first roof plate material 312, itself, by an end first plate material portion 313 a and an end second plate material portion 313 b at both ends thereof. And function as a rain gutter having a plate width 312W. As a result, the roof sheet material 310 of the present embodiment flows rainwater that has penetrated the gap Rd and entered the first roof sheet material 312 side along the upper surface of the first roof sheet material 312 along the roof gradient. Therefore, the rainwater that has entered the first roof plate material 312 is less likely to enter (overflow) from the upper surface of the first roof plate material 312 over the end first plate material portion 313a to the roof assembly YH side. As a result, according to the roof plate material 310 of the present embodiment, the intrusion of rainwater can be reliably prevented, and waterproofing to the rafter N side located below the roof plate material 310 is almost completely achieved.

  Even if heavy rain continues, the rainwater reaching the upper surface of the first roof plate material 312 is limited to rainwater that only penetrates the gap Rd between the end second plate portion 313b and the end third plate portion 313c. Since the first roofing sheet material 312 exhibits a rain gutter function, the volume (height) of rainwater stored on the first roofing sheet material 312 is not so high. Therefore, there is almost no possibility of rainwater reaching the upper surface of the first roof plate 312 until it exceeds the protruding height 313aH of the end first plate member 313a, and the roof assembly beyond the end first plate member 313a. It can be said that the overflow to YH cannot occur.

  The roof plate material 310 of the present embodiment is configured so that the clearance C shown in FIG. 5 is substantially zero when the end first plate material portion 313a is extended to the second roof plate material 314 side of the adjacent roof plate material 310. The end first plate member 313a is brought into contact with the lower surface of the second roof plate member 314 of the adjacent roof plate member 310. For this reason, the overflow of the rainwater itself that tends to flow toward the roof set YH beyond the end first plate member 313a is caused by contact between the end first plate member 313a and the lower surface of the second roof plate 314. Because it can make it harder to get up, the effect of avoiding rainwater infiltration is enhanced. In this case, if the end first plate member 313a is extended from the first roof plate 312 so that the second roof plate 314 is slightly lifted, for example, by one digit after the decimal point, the end first plate member 313a and the second roof plate 314 are extended. Since the weight of the second roof plate member 314 is applied to the abutting portion with the lower surface of the plate, the above overflow avoidance effect is further enhanced. It should be noted that even if the second roof plate material 314 is lifted by the end first plate material portion 313a by about one digit after the decimal point, it does not affect the work of rolling the roof plate material 310, the appearance after firing, or the degree of completion.

  In the roof plate material 310 of the present embodiment, the plate width 312W of the first roof plate material 312 and the protruding height 313aH of the end first plate portion 313a and the protruding height 313bH of the end second plate portion 313b are defined in the dimensions. Therefore, overflow to the roof set YH side beyond the end first plate member 313a can be avoided more reliably. Hereinafter, this point will be described.

  The roof plate material 310 of the present embodiment has a product width 310W of the roof plate material 310 of 450 to 1200 mm (more preferably 600 to 1000 mm), and a width of the plate material width 312W of the first roof plate material 312 that is less than half of the product width 310W. Then, the protruding height of the end plate material was defined as 50 to 150 mm. In addition, the plate width 314W of the second roof plate 314 is made larger than the plate width 312W of the first roof plate 312 and the difference between the widths of both plates is set to 50 to 100 mm. Then, if the product width 310W is a minimum of 450 mm, the first roof plate material 312 can have a plate material width 312W of 175 to 200 mm, and the end portion first plate material portion 313a and the end of the protrusion height of 50 to 150 mm in this width. The second plate member 313b performs a rain gutter function. In other words, the first roof sheet material 312 has a rain gutter shape having a gutter height of 50 to 150 mm and a width of 175 to 200 mm, and is inclined at a roof gradient θ. Therefore, even if heavy rain continues and rains directly on the first roof plate material 312, the rain directly poured on the first roof plate material 312 overflows from the end first plate material portion 313 a or the end second plate material portion 313 b. Without doing so, almost all flows down along the upper surface of the first roof sheet material 312. Even if it rains directly on the first roof plate material 312, it is difficult to overflow the end first plate material portion 313 a, and therefore, the limitation due to the gap Rd of rainwater reaching the upper surface of the first roof plate material 312 and the first roof plate material 312. According to the roof plate material 310 of the present embodiment that performs the restriction by the end third plate material portion 313c that is in contact with the upper surface of the plate, by defining the dimensions as described above, it exceeds the end first plate material portion 313a. Overflow to the roof set YH side can be almost completely avoided. If the width of the product width 310W is increased, the plate width 312W of the first roof plate material 312 is also increased. Therefore, avoidance of overflow to the roof set YH side beyond the end first plate portion 313a is more possible. It will be certain.

  The roof plate material 310 of the present embodiment has various advantages such as the above-described effect of raining and the improvement of reusability, and the shape of the end of the first roof plate material 312 with respect to the first roof plate material 312 is first. The plate member 313a and the end second plate member 313b are bent, and the end second plate member 313b and the end third plate member 313c are bent with respect to the second roof plate 314. Therefore, according to the roof board | plate material 310 of this embodiment, manufacturing cost and construction cost can be reduced by simplification of a shape. More specifically, in order to obtain the roof plate material 310, it is only necessary to subject the flat metal steel plate having the steel plate width 310PW and the length of the roof plate material 310 shown in FIG. It is extremely beneficial in terms of manufacturing cost by simplifying the shape of the mold and reducing the number of press work steps. Moreover, since each of the above-mentioned bends is a vertical bend, the mold shape can be further simplified, and the manufacturing cost reduction effect is enhanced.

  The roof plate material 310 of the present embodiment supports the support of the second roof plate material 314 that has a rolled appearance above the roof set YH, and the end second plate material portion 313b and the end portion third plate material at both ends of the second roof plate material 314. This is accomplished in a self-contained manner by the part 313c. Therefore, according to the roof board | plate material 310 of this embodiment, since the support by adjacent roof board | plate materials 310 is not required, the simplification of a structure and the further reduction of the manufacturing cost accompanying this can be aimed at. Further, the support of the second roof plate material 314 on both sides in the width direction can stabilize the second roof plate material 314 after rolling, and thus the roof plate material 310.

  The roof plate member 310 of the present embodiment uses a fixing mechanism 320 having a first shaft member 321 and a second shaft member 322 for fixing to the roof set YH. As shown in FIG. 4, the fixing mechanism 320 allows the second shaft member 322 to pass through the through hole NH of the roof set YH, thereby simplifying the fixing operation of the roof plate material 310 to the roof set YH. In addition, the fixing mechanism 320 enables the second shaft member 322 to swing around the shaft 321 a of the first shaft member 321, and the base 321 b of the first shaft member 321 is used as the second shaft member 322. The shaft portion of the second shaft member 322 is extended so as to be substantially parallel to the upper end of the end second plate member 313b, and the lower end of the end second plate member 313b, That is, it is made not to protrude from the lower surface of the first roof sheet material 312. As a result, according to the roof plate material 310 of the present embodiment, when the roof plate material 310 is transported or stored, considerations such as damage to the second shaft material 322 are not necessary, and the work is simplified. Moreover, according to the roof plate material 310 of the present embodiment, the attitude of the second shaft material 322 can be maintained by fitting the base portion 321b of the first shaft material 321 to the through hole 322b of the second shaft material 322. The work at the time of carrying and storing the plate material 310 becomes simpler.

  The present invention is not limited to the above-described embodiment, and can be realized with various configurations without departing from the spirit of the present invention. For example, the technical features of the embodiments corresponding to the technical features in each embodiment described in the summary section of the invention are intended to solve part or all of the above-described problems, or part of the above-described effects. Or, in order to achieve the whole, it is possible to replace or combine as appropriate. Further, if the technical feature is not described as essential in the present specification, it can be deleted as appropriate.

  In this embodiment, the roof plate material 310 is formed from a metal steel plate. However, since the cross-sectional shape is simple as shown in FIG. 2 and the like, it may be a molded product of engineer plastic with improved strength. it can. In addition, in the present embodiment, the gap Rd between the adjacent roof plate members 310 is substantially zero mm, but the end portion of the first plate member portion 313a and the end portion of the first roof plate member 312 are as described above. Since the rain gutter function is achieved with the second plate member 313b, the gap Rd may be about 3 to 10 mm. Even in the gap Rd of this level, the infiltration of rainwater into the first roof plate 312 due to the contact of the end third plate member 313c is suppressed, so the roof assembly beyond the end first plate member 313a. There is no change to the YH side, and there is no particular problem. Further, since the gap Rd may remain within the above-described range, the rolling operation is simplified. FIG. 7 is an explanatory diagram showing how to cope when the gap Rd remains to some extent. As shown in the figure, a cap 350 having a length extending from the ridge to the eave and having a substantially T-shaped cross section may be installed in the gap Rd extending in the range of about 3 to 10 mm. In this way, the rainwater intrusion into the gap Rd spreading in the range of about 3 to 10 mm can be suppressed by the cap 350, so that the rainwater reaching the first roof sheet material 312 through the gap Rd is also suppressed. it can. In this case, the cap 350 may be inserted and placed in the gap Rd, or a plate-like or U-shaped rubber may be installed at the lower end and inserted into the gap Rd. In this way, the deviation of the cap 350 can be suppressed.

  In the present embodiment, the first shaft member 321 constituting the fixing mechanism 320 has the base portion 321b, but it may have only the shaft shaft 321a. In this case, even if it exists in the 2nd shaft material 322, what is necessary is just to provide the circular through-hole 322b in the annular body 322a. When the roof plate 310 is transported or stored, the second shaft 322 is rotated so that the second shaft 322 contacts the surface of the end second plate 313b, and then the second shaft 322 is taped. The second shaft member 322 may be temporarily fixed to the second plate member 313b or temporarily fixed so as not to rotate with a rubber fixture having a wedge-shaped cross section.

  In this embodiment, although it applied to the gable roof 100, it is applicable to various roof structures, such as a single-flow roof, a hanging roof, and a saw roof.
