  Although the roof board materials proposed in these publications have excellent advantages such as prevention of rainwater intrusion, further simplification of the shape and associated cost reduction and further simplification of construction are required. .

  In view of the above-described problems, an object of the present invention is to provide a new roof sheet material that further simplifies the structure after ensuring prevention of rainwater intrusion.

In order to achieve at least part of the above object, the present invention can be implemented as the following forms or application examples.
In roof covering materials that use a plurality of roof plate materials that are spread over the roof assembly to form a roof appearance,
Each of the roof sheet materials is
It is formed of a long and predetermined plate material, and has a thatched appearance that hangs from the ridge side of the roof to the eaves side,
An end first member located on one end side in the width direction of the roof plate member;
An end second member located on the other end side in the width direction of the roof plate member,
The first end member is
An upward concave line that opens upward as viewed from the roof assembly extends from the ridge side to the eaves side, and is liquid-tight with the roof plate member on the inner side wall of the upward concave line that contacts the one end side. It is united, and the bottom surface of the upward concave strip is joined to the skin of the roof set to support the roof plate material against the roof set,
The end second member is
A downward concave line that opens downward as viewed from the roof assembly extends from the ridge side to the eaves side, and is liquid-tight with the roof plate member on the inner side wall of the downward concave line that hits the other end side. The first end member that is the upward concave line in the adjacent roof plate member is concealed from its opening side, and the opening side end surface of the inner side wall of the downward concave line is used as the skin of the roof assembly. The roof plate material is supported and bonded to the roof set, and the outer side wall facing the inner side wall of the downward groove is directed to the upper surface of the adjacent roof plate member,
At least one of the plurality of roof plate members is provided with the downwardly concave than the previous SL plurality of roof plate members except the at least one of said roofing sheet material in the wide.

[Application Example 1: Roofing board]
In the roof plate material that is sown in the roof assembly to make the roof appearance,
A roof plate member that is formed of a long and predetermined width plate material, and exhibits a thatched appearance from the roof ridge side to the eaves side,
An end first member located on one end side in the width direction of the roof plate member;
An end second member located on the other end side in the width direction of the roof plate member,
The first end member is
An upward concave line that opens upward as viewed from the roof assembly extends from the ridge side to the eaves side, and is liquid-tight with the roof plate member on the inner side wall of the upward concave line that contacts the one end side. It is united, and the bottom surface of the upward concave strip is joined to the skin of the roof set to support the roof plate material against the roof set,
The end second member is
A downward concave line that opens downward as viewed from the roof assembly extends from the ridge side to the eaves side, and is liquid-tight with the roof plate member on the inner side wall of the downward concave line that hits the other end side. The first end member that is the upward concave line in the adjacent roof plate member is concealed from its opening side, and the opening side end surface of the inner side wall of the downward concave line is used as the skin of the roof assembly. The gist is to join and support the roof sheet material to the roof set, and to make the outer side wall facing the inner side wall of the downward concave strip face the upper surface of the adjacent roof panel member.

  The roofing board material of the application example 1 having the above configuration includes an end first member and an end second member at both ends in the width direction of the roofing board member that exhibits a thatched appearance from the roof ridge side to the eaves side. Since this edge part 1st member and edge part 2nd member are upward or downward recessed stripes seeing from a roof group, respectively, they have an inner side wall at the edge part side of a roof board member, and an outer side wall which faces this. The first end member is liquid-tightly integrated at one end of the roof plate member on the inner side wall of the upward concave strip, and the inner side wall and the outer side wall facing this are both adjacent to each other. Is covered from the opening side with the end second member which is a downward concave line. On the other hand, the second end member is liquid-tightly integrated at one end of the roof plate member on the inner side wall, and the end first member which is an upward concave line in the adjacent roof plate member is opened from the opening side. While covering, the outer side wall facing the inner side wall is directed to the upper surface of the adjacent roof plate member.

  Therefore, when a plurality of roof plate members are arranged in the roof width direction in the roof set, the end first member that is the upward groove and the end second member that is the downward groove at the connecting portion of the adjacent roof plate members are As described above, the end second member extends from the roof ridge side to the eaves side on both sides in the width direction of the roof plate member with the relationship that the end first member is covered from the opening side by the end second member. That is, the end first member that is an upward groove is an action of a ridge that guides rainwater to a low place along the roof gradient while being covered from the opening side by the end second member that is a downward groove. Will be made. And the roof board | plate material which has these both-ends members in a roof board member inclines along a roof gradient, hangs from the ridge side of a roof to the eaves side, and lengthens a roof. In this way, the support for the roof set of the roofing sheet material that covers the roof includes the bottom surface of the upward concave stripe that the first end member joins to the skin of the roof set, and the inner side wall that the second end member joins the skin of the roof set. It is made with the opening side end face. In other words, the support for the roof assembly is self-contained with individual roof plate materials, and does not require support with adjacent roof plate members.

  When rain falls on the roof covered with the roof plate material having the above-described configuration, most of the rainwater flows down with the upper surface of the roof plate member along the roof slope extending from the ridge side to the eaves side. At the connecting portion of the adjacent roof plate members, the end second member that is a downwardly concave groove has its outer side wall directed toward the upper surface of the adjacent roof plate member, so that rainwater that has fallen on the roof is the second end portion. It is possible to enter the inside of the end second member which is a downwardly concave groove from between the outer side wall of the member and the upper surface of the roof plate member. However, the inside of the second end member is covered with the second end member so that the rainwater that has entered the inside of the second end member is recessed upward. It is stopped at the side wall of the first end member. In addition, since the edge first member is inclined in accordance with the roof gradient, the infiltrated rainwater stopped at the side wall of the edge first member flows down along the roof gradient. The effect of preventing intrusion is enhanced.

  Even if rainwater enters over the side wall of the first end member, the intruded rainwater is an upwardly recessed end portion that acts as a gutter while being covered from the opening side by the second end member. Since it enters the first member, it is discharged to the eaves side by this end first member. Therefore, it is possible to reliably prevent rainwater from entering the roof assembly.

  In order to avoid such rainwater intrusion, in the roof sheet material of the above application example 1, at the both ends in the width direction of the roof sheet member, the end first member that is an upward groove and the end second member that is a downward groove are liquid-tight. After the integration, the first end member may be covered with the second end member from the opening side at the connecting portion of the adjacent roof plate members. In other words, not only the rotational symmetry of the members at both ends in the width direction of the roofing board member is required, but also there is no need for support between adjacent roofing boards due to the self-completion of the support for the roof assembly, so the structure is simplified accordingly. And a further reduction in manufacturing costs associated therewith can be achieved. Moreover, in the roof board | plate material of said application example 1, it covers a roof set so that the edge part 1st member which is an upward groove may be covered with the edge 2nd member which is a downward groove at the connection location of an adjacent roof board member. Since it is only necessary to arrange them in the width direction, it is not necessary to perform a work of covering the connecting portion with a separate member, and 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.

  The width of the roof plate member is preferably 450 mm to 1200 mm, more preferably 600 mm to 1000 mm, considering the number of sheets used for the roof. If it is such a dimension, it is preferable also on handling. In addition, the side wall height of the end first member that is the upwardly recessed groove that stops the intruding rainwater as described above is preferably 50 mm to 150 mm from the viewpoint of more reliably preventing the rainwater from being flooded. The edge part 2nd member should just cover this edge part 1st member. In this case, if the top of the side wall of the end first member is close to the inner surface of the lower wall of the end second member that is the downward recess of the adjacent roof plate member, the end of the end second member that is the downward recess In the opening, rainwater can hardly get over the top of the side wall of the first end member, and therefore, rainwater intrusion can be prevented more reliably. By the way, about the 1st end part member which is an upward groove, as mentioned above, it is desirable to set it as the upward groove of the width | variety of about 100-200 mm on account of making this act as a ridge.

  In addition, it is desirable from the viewpoint of workability, durability, and fixing method that the roof plate member and both end members at both ends in the width direction are formed from metal, and particularly steel plate, high purity iron, titanium, stainless steel, aluminum. Etc. are more preferable from the viewpoint of durability. In addition, as a fixing method, a welding method such as spot welding of an overlapping portion, ultrasonic welding, fillet welding, or seamless welding is preferable from the viewpoint of fixing reliability. In this case, the plate thickness of the roof plate member and both end members at both ends in the width direction may be 2 mm to 6 mm in order to avoid so-called warpage and inadvertent deformation, or from the viewpoint of weight.

  The above-mentioned roof board | plate material can be set as the following aspects. For example, for the first end member, the bottom surface of the upward groove is flush with the bottom surface of the roof plate member, and is integrated with the roof plate member on the one end side, Even if it exists in an edge part 2nd member, this makes the said opening side end surface of the inner side wall of the said downward groove the same as the board | plate material bottom face of the said roof board member, and the said roof board member in the said other edge part side. And can be integrated. If it carries out like this, the board | plate material bottom face of a roof board member will be with respect to a roof set with the opening side end surface of the inner side wall of the downward concave strip as an end 2nd member, and the bottom face of the upward concave strip as said end 1st member. Since it can function as a support for the roof, a stable support for the roofing sheet material is possible. In addition, since the bottom surface of the roof plate member is joined to the roof of the roof assembly and the roof plate member itself does not float up from the roof assembly, even if an operator gets on the roof plate member, it does not cause a depression or the like. . For this reason, the workability | operativity of a whispering work increases.

  Moreover, about the said edge part 2nd member, this can be bent and formed so that the said roof board member may become the said downward groove on the said other edge part side. If it carries out like this, the liquid-tightness of an edge part 2nd member and a roof-plate member will be ensured easily, and it will become simple. In this case, the first end member is provided with an outer side wall facing the inner side wall of the upward concave strip by bending the roof plate member upward on the one end side. In addition, the inner side wall of the upward concave strip can be formed by standing a flat plate forming the inner side wall on the upper surface of the roof plate member so as to face the bent outer side wall. In this way, by securing the liquid tightness when the flat plate forming the inner side wall is erected on the upper surface of the roof plate member, the liquid tightness between the end first member and the roof plate member is easily ensured, It becomes simple.

  In addition, a fixing shaft material for pulling and fixing toward the roof set can be projected on at least one of the bottom surface of the roof plate member or the bottom surface of the upward concave line in the first end member. If it carries out like this, after rolling a roof with a roof board | plate material, the roof board | plate material can be pulled toward a roof group via this fixing shaft, and can be fixed.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram for schematically explaining the overall configuration of a roof 100 that has been spread using the roof plate material 310 of the present embodiment. First, the overall configuration will be described with reference to FIG.

  As shown in the figure, the roof 100 of the present embodiment includes a gable-type roof set YH, and left and right roof covering materials 110L and 110R are attached to both sides of the roof set YH with a predetermined roof slope, and roof roof materials on both sides of the roof are attached. 110L and 110R are configured to be covered with a wrap 120 in the ridge. The roof covering materials 110L and 110R are hung from the purlin MB in the roof set YH to the eaves NB, that is, the roof is hung from the roof ridge side to the eaves side to form a roof appearance. 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 rectangular through holes NH into which long bolts for fixing the roof plate 310 described later are 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. FIG. 5 is an explanatory view showing a manufacturing mode of the roof plate material 310, FIG. 5 is an explanatory view showing the relationship between the dimensions of the roof plate material 310 and a state in which the roof plate material 310 is connected, and FIG. It is a schematic perspective view of the roof board | plate material 310RE arrange | positioned in. The roof covering material 110R is the same as the roof covering material 110L, and only that side is different.

  As shown in these drawings, a roof plate member 310 includes a roof plate member 312 formed of a long and predetermined width metal steel plate (for example, a steel plate made of titanium or stainless steel having a thickness of about 5 mm), a roof plate member 312, and a roof plate member 312. Left and right joining members 314 </ b> R and 314 </ b> L positioned on both ends in the width direction of the plate member 312, and a long bolt 316 for fixing. The roof plate member 312 has a thatched appearance from the ridge side of the roof 100 to the eaves side, and is inclined at a roof gradient θ in the roof set YH.

  The long bolt 316 extends downward from the bottom surface of the roof plate member 312 at substantially the center in the width direction of the roof plate member 310. The long bolt 316 is joined to the bottom surface of the roof plate 310 and fixed in a liquid-tight manner by a method such as seamless welding. When the roof set YH is rolled by the roof plate 310, the long bolt 316 penetrates the through hole NH of the rafter N. The male screw part is projected below the rafter N. The long bolts 316 are provided on the bottom surface of the roof plate member 312 at the eaves side, the ridge side, and the center thereof. Therefore, the through hole NH of the rafter N is formed in the rafter N so that the three long bolts 316 can be inserted (see FIG. 1).

  As shown in the drawing, the joining member 314L located at the left end portion of the roof plate member 312 is formed as a downward concave line opened downward as viewed from the roof set YH by bending the left end of the roof plate member 312. It has an inner side wall 314Li on the side of the roof plate member 312 and an outer side wall 314Lo facing it. The joining member 314L is formed in a liquid-tight integral with the roof plate member 312 in the inner side wall 314Li corresponding to the left end portion of the roof plate member 312 through bending of the roof plate member 312 and has a downward groove. The roof 100 extends from the ridge side to the eaves side, and is inclined at a roof gradient θ. In this case, the liquid-tight integrated part with the roof plate member 312 is the opening side end of the inner side wall 314Li, and the joining member 314L is flush with the plate bottom surface of the roof plate member 312 with the opening side end surface of the inner side wall 314Li. To do.

  The joining member 314R located at the right end of the roof plate member 312 is formed as an upward concave line that opens upward as viewed from the roof set YH, and the outer side wall 314Ri on the side of the roof plate member 312 faces the outside. Side wall 314Ro. The joining member 314R forms the outer side wall 314Ro by bending the right end of the roof plate member 312. The inner side wall 314R is erected in a liquid-tight manner from the upper surface of the roof plate member 312. An upward concave line is formed, extends from the ridge side of the roof 100 to the eaves side, and is inclined at a roof gradient θ. In this case, the liquid-tight integrated part with the roof plate member 312 is on the base side of the inner side wall 314Ri, and the joining member 314R uses the bottom surface of the upward concave line between both the inner side walls as a plate material of the roof plate member 312. It is flush with the bottom.

  The liquid-tight erection of the inner side wall 314Ri from the upper surface of the roof plate member 312 can take various forms. That is, as shown in FIG. 4, the plate material forming the inner side wall 314Ri is erected on the upper surface of the roof plate member 312 and the base portion, which is the joint portion, is liquid-tight over the inner side wall longitudinal direction by a technique such as seamless welding. (See FIG. 4A). The joining member 314R is previously formed as an upwardly concave groove with the inner side wall 314Ri and the outer side wall 314Ro, the roof plate member 312 is joined to the base of the inner side wall 314Ri, and the joining portion is stretched in the longitudinal direction of the inner side wall by a technique such as seamless welding. To fix the liquid tightly (see FIG. 4B). Alternatively, as shown in FIG. 4C, the roof plate member 312 is bent upward and downward to form the inner side wall 314Ri, and the outer side wall 314Ro is formed by bending the right end of the roof plate member 312. In any of the forms described above, the joining member 314R is liquid-tightly integrated with the roof plate member 312 on the inner side wall 314Ri corresponding to the right end of the roof plate member 312. It extends from the ridge side of the roof 100 to the eaves side with an upward concave line.

  Next, the relationship between the joining member 314L and the joining member 314R located at both ends in the width direction of the roof plate member 312 will be described. As shown in FIG. 5, the downward concave joining member 314 </ b> L has an in-groove dimension 314 </ b> Lw between the inner wall surfaces of the facing inner side wall 314 </ b> Li and the outer side wall 314 </ b> Lo, and an outer dimension 314 </ b> Rw of the upward concave joining member 314 </ b> R. The outer dimension between the outer wall surfaces of the inner side wall 314Ri and the outer side wall 314Ro is made wider. Further, the joining member 314L has a groove depth 314Lh from the opening side end of the inner side wall 314Li to the bottom wall surface of the groove larger than the side wall height 314Rh from the bottom surface of the joining member 314R to the opening ends of both the inner and outer side walls. Yes. Further, the joining member 314L ensures a clearance C of several mm (preferably 1 to 3 mm) from the opening end of the outer side wall 314Lo facing the inner side wall 314Li on the roof plate member 312 side to the upper surface of the roof plate member 312. The outer side wall 314Lo is extended.

  As a result, when the roof sheet material 310 is lined up in the roof set YH (see FIG. 1), as shown in FIG. 5, the bonding member 314L has the bonding member 314R that is an upward concave line in the adjacent roof panel member 312 While concealing from the opening side, the joining member 314L is directed to the upper surface of the adjacent roof plate member 312. Between the bottom wall surface of the recess of the joining member 314L when the joining member 314L is covered with the joining member 314L and the inner and outer side wall opening ends of the joining member 314R, the side wall height 314Rh and the side wall height 314Rh described above are provided. The difference remains as the clearance Hc, and the difference between the groove inner dimension 314Lw and the outer dimension 314Rw described above is between the inner side surface of the inner and outer side walls of the joining member 314L and the outer side surface of the inner and outer side walls of the joining member 314R. It remains as clearance Wc. The left and right clearances Wc are determined according to the position of the joining member 314R in the joining member 314L. If the joining member 314R is covered at the center of the joining member 314L, the clearance Wc is equal (half the difference). Further, the clearance C described above remains between the opening side end of the outer side wall 314Lo of the joining member 314L and the upper surface of the roof plate member 312. And each roof board | plate material 310 is a board | plate material of the roof board | plate member 312 made into these in addition to the opening side end surface of inner side wall 314Li in the bottom face of the joining member 314R which is an upward concave strip, and the joining member 314L which is a downward concave strip. The bottom surface is joined to the skin of the roof set YH and supported by the roof set YH. As shown in FIG. 3, each of the roof plate members 310 supported in this manner penetrates the through holes NH of the rafters N through long bolts 316 extending from the bottom surface of the plate member of the roof plate member 312. Therefore, the rowing operator interposes the holding plate Bp and the washer W on the lower surface side of the rafter N, and then screwes the nut Nt into the male screw portion of the long bolt 316, thereby each of the roof plate members 310. Are attracted and fixed to the rafter N side of the roof set YH.

  The width 310W of the above-mentioned roof plate material 310 is made equal to, for example, the forming width of the flat plate steel plate, and the length is manufactured and processed according to the length from the roof ridge to the eave to be constructed, and is carried into the construction site. The Moreover, it is preferable that the groove depth 314Lh and the side wall height 314Rh of the joining member 314L and the joining member 314R are short with respect to the width 310W of the roof plate material 310, so that the roof looks after firing and functions as a later-described ridge. Should be determined in consideration of For example, if the width 310W of the roof plate 310 is 450 to 1200 mm (more preferably 600 to 1000 mm), the side wall height 314Rh and the outer dimension 314Rw of the joining member 314R are secured as described later. From the viewpoint of preventing rainwater intrusion, the side wall height 314Rh may be 50 to 150 mm and the outer dimension 314Rw may be 100 to 200 mm. For the joining member 314L, the groove depth 314Lh and the in-groove dimension 314Lw may be determined so as to cover the joining member 314R having the above dimensions from the opening side.

  In addition, as shown in FIG. 2, the roof roof material 110 </ b> L includes a rain closing plate 330 on the ridge side upper surface of the roof plate material 310. The rain finishing plate 330 is installed so as to block the ridge-side opening of the joining member 314L of the roof plate member 310 wound on the roof set YH and to rise from the ridge-side end surface of the roof plate member 312. Therefore, the rain finishing board 330 moves rainwater which is going to move against the roof gradient θ in the groove of the joining member 314R covered with the upper surface of the roofing board member 312 and the joining member 314L and the ridge side opening of the joining member 314L and Damping is performed at the ridge side end face of the roof plate member 312. In addition, the rain finishing board 330 is seamlessly welded to the ridge side end face of the roof board member 312 and is reinforced with L-shaped steel or the like (not shown) at the joint / fixed portion.

  In the present embodiment, as described above, the roof is vertically wound with the plurality of roof plate members 310, but the roof side of the roof has a roof plate member 310RE in order to enhance the appearance of thatched portion. As shown in FIGS. 2 and 6, the roof plate member 310RE is disposed at the end of the roof covering member 110L that is on the right side, and is an end portion of the roof plate member 312 having the joining member 314L and the long bolt 316. And an end plate 340R surrounding the rafter N on the wife side. The end plate 340R rises from the roof plate member 312 in the same manner as the joining member 314L and then descends outside the rafter N to cover the rafter N. In the left side of the roof, a roof plate material having a configuration in which the roof plate material 310A is mirror-reversed is used.

  The roof plate material 310RE has an indefinite width, whereas the above-described roof plate material 310 has a fixed width. That is, since the roof width between the roof wives is various, the width of the roof plate material 310RE is individually determined for each roof to be spun from the roof width and the width of the roof plate material 310.

  The roof covering material 110R uses the above-described roof plate materials 310 and 310RE, and the roof covering material 110L is different only in the roofing side of the roof, and is not different in structure from the roof covering 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 roof plate material 310RE, and is fixed to the roof set YH by an appropriate fixing means. Complete all.

  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 rolling operation, and in this case, the bonding member 314R which is a connecting portion of the adjacent roof plate members 312 is connected to the bonding member. What is necessary is just to make it cover with 314L. 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, when the respective roof plate members 310 are placed, the long bolts 316 protrude from the roof plate member 312 through the rafters N. Therefore, the long plate bolts 316 are used to extend the roof plate member 312. The roof plate 310 can be easily fixed by being drawn to the skin of the roof set YH.

Here, the rain closing which the roof 100 of a present Example 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) along with the rain that has directly poured onto the roof covering materials 110L and 110R. Rain that has poured from above almost without a strong wind does not flow on the ridge side on the top surface of the roof plate member 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 typhoons (strong wind rain) may try to flow on the roof side of the roof plate member 312 against the roof slope 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 performance plate 330 in FIG.

  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. 5, the adjacent roof plate members 310 cover the joining member 314 </ b> R corresponding to the connecting portion with the joining member 314 </ b> L, so that both the joining members are not mechanically coupled. As described above, the clearance C remains between the upper surface of the roof plate member 312 and the opening side end surface of the outer side wall 314Lo. Rainwater passes through this clearance C, but does not enter the interior after that, as described below, and it is completely absent, and waterproofing to the side of the rafter N located below the roof plate 310 is almost completely achieved. Is done. That is, in order for rainwater to enter the rafter N beyond the clearance C, rainwater that has entered from the opening side end surface of the outer side wall 314Lo of the joining member 314L is inside the joining member 314R covered with the joining member 314L. Rain water must go over the side wall 314Ri, which is impossible.

  Even if there is a large amount of rain and a rainwater layer can be formed on the roof plate member 312 of the roof plate material 310, the roof plate material 310 is inclined at the roof slope θ, so the rainwater in this rainwater layer always flows down to the eaves side, There is no possibility that the rainwater layer continuously exceeds the protruding height (side wall height 314Rh) of the inner side wall 314Ri of the joining member 314R covered with the joining member 314L. Further, even if rainwater enters beyond the protruding height of the inner side wall 314Ri for some reason, the upward concave joint member 314R formed by the inner side wall 314Ri and the outer side wall 314Ro is inclined with a roof gradient θ. Since it acts as a kite, the infiltrated rainwater flows down at the slope of the roof slope θ described above.

  Furthermore, according to the present embodiment, in order to obtain the roof 100 capable of exhibiting various advantages such as the above-described effect of finishing rain and the improvement of reusability, the roof plate 310 that spreads the roof 100 is formed into a flat plate shape. A structure in which a joining member 314R that is an upward concave line and a bonding member 314L that is a downward concave line are integrated in a liquid-tight manner at both ends in the width direction of the roof plate member 312 and a joining member 314R that is a connecting point between adjacent roof plate members 312 It is merely a structure in which the bonding member 314L covers the opening side. In such a structure, the rotational symmetry of the shape of the joining members 314R and 314L at both ends in the width direction of the roof plate member 312 and the installation position of the roof plate member 312 with respect to both joining members is not required. Moreover, according to the present embodiment, the support of the roof plate member 310 with respect to the roof set YH is added to the bottom surface of the joint member 314R that is an upward concave line and the opening side end surface of the inner side wall 314Li in the joint member 314L that is a downward concave line, and This is accomplished in a self-contained manner by joining the flat plate bottom surface of the roof plate member 312 to the skin of the roof set YH. Therefore, according to the roof board | plate material 310 of a present Example, since the support in 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.

  Moreover, in the roof board | plate material 310 of a present Example, the roof board | plate material 310 is made to cover the roof set YH so that the joining member 314R which is an upward concave strip may be covered with the joint member 314L which is a downward concave strip in the connection location of the adjacent roof board member 312. All you need to do is arrange them in the width direction of the roof. Therefore, according to the roof board material 310 of the present embodiment, it is not necessary to perform a work of covering the connecting portion with a member different from the roof board material 310, further simplifying the rolling work and reducing the construction cost associated therewith. Can be planned.

  Moreover, in the roof board | plate material 310 of a present Example, in joining the joining member 314R and the joining member 314L to the both ends of the width direction of the roof board member 312 liquid-tightly, it is a joining member which makes the board | plate material bottom face of the roof board member 312 upward concave. The bottom surface of 314R and the opening side end surface of the inner side wall 314Li in the bonding member 314L which is a downward concave line are flush with each other. Therefore, the roof plate member 310 has a bottom surface of the plate member bottom surface of the roof plate member 312 over a wide range in addition to the support by joining the bottom surface of the joint member 314R and the opening side end surface of the inner side wall 314Li of the joint member 314L to the skin of the roof set YH. The roof set YH is also supported by the roof set YH by joining to the skin. For this reason, according to the present Example, the roof board | plate material 310 can be supported very stably with respect to the roof set YH, and it is preferable. Moreover, the roof plate member 312 can be prevented from floating from the roof set YH by joining the bottom surface of the plate member to the skin of the roof set YH. For this reason, it is possible to prevent sinking or the like even if an operator gets on the roof plate member 312 in the work of the rolling work, the repair or the inspection, so that the workability of the rolling work or the like can be improved.

  Moreover, about the joining member 314L which has outer side wall 314Lo and inner side wall 314Li, it formed so that it might become a downward groove by bending the roof-plate member 312 on the edge part side. Therefore, the liquid tightness between the joining member 314L and the roof plate member 312 can be easily secured, which is simple. In this case, for the joining member 314R having the outer side wall 314Ro and the inner side wall 314Ri, the outer side wall 314Ro is formed by bending the roof plate member 312 upward on the end side, and the inner side wall 314Ri is This was formed by standing upright on the upper surface of the roof plate member 312 so that the flat plate forming the inner side wall faces the outer side wall 314Ro formed by bending (see FIG. 4A). Therefore, by ensuring the liquid-tightness when the flat plate forming the inner side wall 314Ri is erected on the upper surface of the roof plate member 212, the liquid-tightness between the joining member 314R and the roof plate member 212 can be easily ensured. It is.

  In the present embodiment, the joint member 314 </ b> R is covered with the joint member 314 at the connection portion between the adjacent roof plate members 312, and the clearance C is formed between the open end of the outer side wall 314 </ b> Lo and the upper surface of the roof plate member 312. Secured. In addition to this, a clearance Hc is also secured between the bottom wall surface of the recess of the joining member 314L and the opening ends of both the inner and outer side walls of the joining member 314R. For this reason, even if each member of the roof plate member 310 expands due to an increase in the atmospheric temperature or an increase in sunlight, the opening end of the outer side wall 314Lo does not contact the upper surface of the roof plate member 312 or In addition, since excessive force can be prevented from being applied to the outer side wall 314Lo, the bending and warping of the outer side wall 314Lo can be suppressed. The same applies to the bottom wall surface of the concave strip of the joining member 314L and the opening ends of both inner and outer side walls of the joining member 314R, and the curvature and warpage of the bottom wall of the concave strip of the joining member 314L and both the inner and outer side walls of the joining member 314R can be suppressed. .

  Next, a modified example will be described. FIG. 7 is a view corresponding to FIG. 5, and is an explanatory view showing a configuration of the roof plate material 310 </ b> A according to a modified example and a state where the roof plate material 310 </ b> A is connected in a cross-sectional view.

  As shown in the figure, the roof plate material 310A of this modification is characterized in that the downwardly-groove joint member 314L is wider than the joint member 314R. The width can be variously set, but the joining member 314L occupies approximately 1/4 to 1/2 of the width 310W (450 to 1200 mm) of the roof plate 310, and the joining member 314R has an outer dimension of 100 to 200 mm. 314Rw. The groove depth 314Lh of the inner side wall 314Li in the bonding member 314L and the side wall height 314Rh of the bonding member 314R are as described above, from the opening end of the outer side wall 314Lo in the bonding member 314L to the upper surface of the roof plate member 312. The same applies to the clearance C.

  The roof plate material 310A of this modification has the following advantages. When the roof plate members 310A are arranged side by side, as shown in FIG. 7, the degree of freedom of the position occupied by the bonding member 314R when the bonding member 314R serving as a connection point between adjacent roof plate members 312 is closed with the bonding member 314L, as shown in FIG. Will increase. Therefore, since the gap between the roof plate material 310A and the roof plate material 310A that are adjacent to the roof can be adjusted, versatility to change the roof width of the roof set YH is enhanced.

  FIG. 8 is an explanatory view showing the construction and connection state of a roof plate material 310B of another modified example corresponding to FIG. 5 in a sectional view, and FIG. 9 is an explanatory view showing a further modification of the roof plate material 310B.

  The roof plate member 310B of the modification shown in FIG. 8 has the roof plate member 312 displaced from the bottom surface of the joining member 314R and the opening side end surface of the inner side wall 314Li in the joining member 314L. This roof plate material 310B is different from the above-described embodiment in that the roof plate member 312 is rolled up in a state where the roof plate member 312 is slightly floated from the skin of the roof set YH. However, the support of the roof plate member 310B with respect to the roof set YH is obtained by joining the bottom surface of the joining member 314R at both ends in the width direction of the roof plate member 312 and the opening side end surface of the inner side wall 314Li in the joining member 314L to the skin of the roof set YH. Since it can be secured, there is no hindrance to the roofing, and the above-mentioned suitable rain performance can be exhibited.

  In FIG. 9, a block material 312 </ b> B corresponding to a gap between the bottom surface and the skin of the roof set YH is arranged on the bottom surface of the roof plate member 312. By doing so, the roof plate member 312 can be supported with respect to the roof set YH via the block material 312B, so that the roof plate member 310B can be prevented from being depressed during the rolling operation or the like.

  As mentioned above, although the embodiment of the present invention has been described in the embodiments, the present invention is not limited to the above-described embodiments and modifications, and can be implemented in various modes without departing from the gist thereof. Is possible. For example, the roof plate material 310 of the embodiment and its modified example have a simple cross-sectional shape as shown in FIG. 5 and the like, so that a metal mold product using upper and lower mating dies and strength improvement can be achieved. It can also be a molded product of engineer plastic. In addition, the long bolt 316 is provided on the bottom surface of the roof plate member 312, but may be provided on the bottom surface of the joining member 314 </ b> R or on both bottom surfaces of the roof plate member 312 and the joining member 314 </ b> R.

  In addition, in this embodiment, the gap between the open end of the outer side wall 314Lo and the top surface of the roof plate member 312 or between the bottom wall surface of the recess of the joint member 314L and the open ends of both the inner and outer side walls of the joint member 314R is already present. Although the clearance described above is secured, the opening end of the outer side wall 314Lo is in contact with the upper surface of the roof plate member 312 or the opening ends of both the inner and outer side walls of the joining member 314R are in contact with the bottom wall surface of the recess of the joining member 314L. It can also be done. This is because if the steel plate for forming the roof plate 310 has a certain thickness, the possibility of bending or warping is low. Then, if the above-mentioned opening end is brought into contact, rainwater passes from the opening side end surface of the outer side wall 314Lo to the inner side of the joining member 314R, and from the opening side end surface of the inner side wall 314Rin to the inner side joining member 314R. The rainwater passage to the groove can be suppressed.
