Japanese Patent No. 3995907

The building exterior structure described in Patent Document 1 has a high-level balance of various performances such as workability, rain-proofing performance, and maintenance of designability (prevention of deterioration). For example, both ends of the roofing material stand by about 25 mm. Compared to a roof with a simple structure that is just raised (a structure in which standing pieces of about 25 mm are butted and seam welded), the durability is significantly superior, especially when a load is applied.
However, in the above-mentioned Patent Document 1, the structure of the roof eaves is not mentioned (described) in the document itself, and an effective structure including the construction (connection) of the eaves gutter has been sought.

Therefore, the present invention is a metal vertical roof plate that can be laid only by mounting means such as fitting, partially welded together, or entirely welded together, and a roof using the same. The purpose is to propose the end structure of.

The present invention has been proposed in view of the above, and is a metal vertical roofing plate made of a metal plate material having a mounting portion formed on a side edge of a face plate portion, and the mounting portion is raised from the face plate portion to the surface side.

Is the sum L2 of the horizontal distance from the center line between the roof plates to the base end of the molded part and the vertical distance from the face plate part to the lower end of the abutting part the same when the vertically-roofed roof plates that are adjacent to each other in the horizontal direction are laid? Or, where L1 <L2, the molded portion has an inner rising portion that rises from the face plate portion to the surface side and an outer rising portion that is located further outside the inner rising portion and rises toward the face plate portion. The length S1 of the metal plate material forming the inner rising portion and the horizontal distance S2 from the base end of the inner rising portion to the lower end of the abutting portion are the same or S1 <S2. It proposes a metal vertical roofing plate (hereinafter referred to as a vertical roofing plate of the first invention) characterized by the above.
In the following description, the above condition is defined as condition Y.

Further, in the present invention, the mounting portion is formed of a metal plate material having a mounting portion formed on the side edge of the face plate portion, and the mounting portion is formed by a molded portion formed in a raised shape from the face plate portion to the surface side, and further of the molded portion. It consists of an abutting portion that is located on the outside and stands up to the surface side, and the length (= total length of the molded portion) L1 of the metal plate material that forms the molded portion and the vertically adjacent vertical roof plates that are adjacent to each other in the horizontal direction are laid. A metal vertical roofing plate in which the sum L2 of the horizontal distance from the center line between the roof plates to the base end of the molded portion and the vertical distance from the face plate portion to the lower end of the abutting portion is the same or L1 <L2. , It is an end structure formed by connecting adjacent to each other in the horizontal direction, and each of the above- mentioned moldings is in a state where the abutting portions of the vertically-roofed roof plates adjacent to each other in the horizontal direction face each other. We also propose a roof end structure characterized in that a part of the portion is processed horizontally or vertically, and the abutting portions facing each other are welded and tilted horizontally.

Further, the present invention is an end structure formed by connecting the vertically-roofed roof plates of the first invention side by side in the horizontal direction, and the above-mentioned hits of the vertically-roofed roof plates adjacent to each other in the horizontal direction. It is characterized in that a part of each of the molded portions is processed horizontally or vertically with the contact portions facing each other, and the facing contact portions are welded and tilted horizontally. It also proposes the edge structure of the roof.

The vertical roofing plate made of metal of the present invention is molded under the condition that it can be laid only by mounting means such as fitting or engaging, or it can be mounted in combination with partial or whole welding. The dimension of the total length L1 of the portion and the sum L2 of the horizontal distance from the center line between the roof plates adjacent to each other in the lateral direction to the base end of the molded portion and the vertical distance from the face plate portion to the lower end of the contact portion is L1 ≦ L2.

The metal vertical roofing plate of the present invention is a metal vertical roofing plate made of a metal plate material having a mounting portion formed on a side edge of the face plate portion, and the mounting portion is raised from the face plate portion to the surface side. A molded portion and a contact portion that is located further outside the molded portion and stands up to the surface side, and the length (= total length of the molded portion) L1 of the metal plate material forming the molded portion. Is the sum L2 of the horizontal distance from the center line between the roof plates to the base end of the molded part and the vertical distance from the face plate part to the lower end of the abutting part the same when the vertically-roofed roof plates adjacent to each other in the horizontal direction are laid? It is characterized in that L1 <L2.
That is, the condition X of the metal vertical roof plate is the total length L1 of the molded portion, the horizontal distance from the center line between the roof plates adjacent to each other in the lateral direction to the base end of the molded portion, and the distance from the face plate portion to the lower end of the contact portion. The dimension with the sum L2 with the vertical distance is L1 ≦ L2.
Further, when the molded portion includes an inner rising portion that rises from the face plate portion to the surface side and an outer rising portion that is located further outside the inner rising portion and rises toward the face plate portion, the inner side is a condition Y. It is desirable that the length S1 of the metal plate material forming the rising portion and the horizontal distance S2 from the base end of the inner rising portion to the lower end of the abutting portion are S1 ≦ S2.

The structure laid on the base of the metal vertical roof plate of the present invention may be laid only by mounting means such as fitting, engaging, and tightening with a holding member such as a hanger fixed to the base. It may be attached in combination with partial or total welding. That is, the molded portion may be laid only by known mounting means such as fitting or engaging, or the abutting portion may be laid by welding partially or entirely by welding. In addition, partial welding refers to welding the joints and ends of water, underwater, etc. by seam welding or the like.

Before verifying the condition X and the condition Y, the molded portion is a portion to be attached to a holding member such as a hanger fixed to the base by mounting means such as fitting, engaging, and tightening, and this molding. Even when the part consists of an inner rising part and an outer rising part, many findings have been obtained from many past cases, but the following three findings are shown.
First, both the inner rising part and the outer rising part are formed in a raised shape (the former is a mountain shape that rises from a horizontal plane and the latter is a mountain shape that rises from a vertical plane), so that the shape configuration of the holding member (holding part) is simple. It is desirable in that.
Secondly, the inner rising portion is required to have the effect of blocking the influence (tensile stress toward the face plate portion) even if the face plate portion flutters when a load weight acts on the vertically-roofed roof plate. It is desirable that the close rising pieces are held at an angle toward the face plate portion.
Thirdly, since various external members such as a solar cell panel may be placed on the upper surface of the outer rising portion, the rising piece near the contact portion is horizontally extended and held. Is desirable.

The vertically-roofed roof plate is not particularly limited as long as it is attached to a holding member whose molded portion is fixed to the base by fitting, engaging, tightening or the like. Further, it may be used in combination with partially welding a part of the contact portion (joining portion or end portion such as above or below water) or in combination with welding the entire contact portion. Seam welding is the most desirable as welding.

The roof end structure formed by connecting the vertically-roofed roof plates side by side in the horizontal direction has a state in which the contact portions of the vertically-roofed roof plates adjacent to each other in the horizontal direction face each other. Each molded portion is processed horizontally and vertically, and the abutting portions facing each other are welded and tilted horizontally.

The molded portion is configured to be attached to a holding member such as a hanger fixed to the base by mounting means such as fitting, engaging, and plumb bob tightening, and any known configuration may be applied, but the end It is desirable to mold the bent portion (corner portion) into a bent shape (arc shape) as shown in the illustrated embodiment described later in preparation for the horizontal processing and the vertical processing applied to the molded portion.
That is, the bent portions (corner portions) in the inner rising portion and the outer rising portion are bent as shown in the illustrated embodiment so that the horizontal processing and the vertical processing can be performed without causing folding or the like. It is desirable to mold it into a shape (arc shape).
In addition, the cause of folding is often a complicated combination of horizontal processing and vertical processing. Such a case can be solved by dividing the processed portion into small pieces and performing each processed in a plurality of times, or by performing the processed portion while the operator assistsly pulls the processed portion at the time of processing.

Further, the means for connecting the vertically-roofed roof plate to the vertically adjacent vertical-roofed roof plates in the horizontal direction is not particularly limited, and the cover material (cap) is used as long as the contact portions are connected to each other so as to face each other. It may be connected by using a material) or the like, or may be partially or wholly seam-welded to each other.
Such a vertically-roofed roof plate is formed from a known metal material or the like, and is formed (molded) by roll molding, press molding, or a combination of both, and the material thickness thereof is not particularly limited. However, it is about 0.4 to 1.6 mm.

The horizontal processing applied to the molded part is to process the part where the deformation in the vertical (Y-axis) direction is larger than that in the horizontal (X-axis) direction, that is, to process the inner rising part etc. horizontally. It is done with a jig that is sandwiched from above and below. In addition, the vertical processing applied to the molded part is processing to a place where the deformation in the horizontal (X-axis) direction is larger than that in the vertical (Y-axis) direction, that is, the outer rising portion is processed vertically. It is done with a jig that sandwiches it from the left and right.

It is desirable to weld by seam welding in order to weld the abutting portions of the vertically-roofed roof plates that are adjacent to each other in the lateral direction. In this step, a large current is passed through the abutting portions facing each other, heated by the resistance heat generated there, and pressure is applied to continuously perform welding.
It is desirable that this seam welding is continuously performed from the vicinity of the edge to the inside.

In order to tilt the welded contact portion horizontally, the jig or the like to be used is not particularly limited, and the welded contact portion may be tilted horizontally by repeatedly performing a weak impact with, for example, a mallet or the like.

In the roof end structure constructed by using the vertical roof plate of the present invention, the edge of the roof surface is formed horizontally, so that members such as eaves gutters can be easily and neatly attached. For example, it is possible to attach an eaves gutter to the eaves edge of the roof surface by the seam welding.

In the schematic view shown in FIG. 1 (a), the horizontal face plate portion (11) rises vertically, and the upper end thereof is bent horizontally to form an L-shaped molded portion (12). An aspect is shown in which the tip thereof is raised vertically to form a contact portion (13).
In this embodiment, the total length L1 of the molded portion (12) is the horizontal piece A1 + the vertical piece A2, but the horizontal distance from the center line C between the roof plates adjacent to each other in the horizontal direction to the base end of the molded portion is A1, and the face plate. Since the vertical distance from the portion to the lower end of the contact portion is A2, the sum L2 is A1 + A2, so L1 = L2 and the above condition X is satisfied.
The vertically-roofed roof plate (1st embodiment) 1A of FIG. 1B in which the L-shaped molded portion 12A is formed in this way satisfies the above condition X. However, if only the L-shaped molded portion 12A is to be held, a holding member can be easily assumed, but when considering mounting stability and the like, a holding member having a complicated structure is required. Low practical value.

In the schematic view shown in FIG. 2A, as a more specific molding portion, the side adjacent to the face plate portion (11) is the inner rising portion (121), and the side adjacent to the contact portion (13) is the outer rising portion. (122) is considered.
In this embodiment, both the inner rising portion (121) and the outer rising portion (122) constituting the molded portion are formed in an L shape orthogonal to each other, and each piece is made the same (B1). The total length L1 of the molded portion including the inner rising portion (121) and the outer rising portion (122) is B1 × 4. The horizontal distance from the center line C between the roof plates adjacent to each other in the lateral direction to the base end of the molded portion (= the base end of the inner rising portion) is B1 × 2, and the lower end from the face plate portion (11) to the contact portion (13). Since the vertical distance up to is B1 × 2, the sum L2 is B1 × 4, so L1 = L2 and the above condition X is satisfied.
The vertically-roofed roof plate (second embodiment) 1B of FIG. 2B in which the L-shaped inner rising portion 121 and the L-shaped outer rising portion 122 are formed in this way satisfies the above condition X. If only these L-shaped inner rising portions 121 and outer rising portions 122 are to be held, a holding member can be easily assumed. Since there are two places, the mounting stability is improved accordingly. In this case, for example, as in the vertical roof plate 1B'shown in FIG. 2C based on the first finding, the inner rising portion 121'is formed in an upwardly raised shape, and the outer rising portion 122 is formed. As a', it may be deformed so as to be formed in a raised shape toward the face plate portion 11B side.

The condition Y will be described with reference to the drawings.
In FIG. 2, since all the horizontal piece dimensions and the vertical piece dimensions constituting the molded portion are the same B1, the length S1 of the metal plate material forming the inner rising portion is B1 × 2, and the inner rising portion has the same length. Since the horizontal distance S2 from the base end to the lower end of the contact portion is also B1 × 2, S1 = S2 and the above condition Y is satisfied.

The condition Y is not necessarily limited to the above-described embodiment, and for example, as shown in FIG. 3A, the line x having the face plate portion extending horizontally and the contact portion extending vertically. At an arbitrary position located on the bisector z extending from the intersection where the vertical line y intersects orthogonally, a congruent rectangle is formed at the lower left and upper right thereof, so that the metal forming the inner rising portion is formed. Both the length S1 of the plate material (L-shaped body 121c ") and the horizontal distance S2 from the base end of the inner rising portion to the lower end of the abutting portion are the vertical and horizontal lengths C1 + C2 of the rectangle, and the above condition Y is satisfied.
At an arbitrary position located below the bisector z, a rectangle (L-shaped) having a smaller vertical and horizontal length than the rectangular (L-shaped) is formed at the lower left, so that S1 <S2. Therefore, even in that case, the above condition Y is satisfied.

In the schematic diagram shown in FIG. 3A, an L-shaped body (121c ") whose vertical and horizontal directions are C2 + C1 and an L-shaped body (122c") whose vertical and horizontal directions are C1 + C2 are formed. In this case, for example, based on the second finding, the rising piece close to the face plate portion (11) is inclined toward the face plate portion (11) as shown in the inner rising portion 121c shown in FIG. 3 (b). The L-shaped body (121c ") may be modified according to the embodiment. Therefore, in the vertically-roofed roof plate (third embodiment) 1C shown in FIG. 3 (c), the inner rising portion 121c is directed to the face plate portion 11 side. It is formed in an inclined ridge shape, and the outer rising portion 122c is formed in an angry shoulder shape.
The vertically-roofed roof plate 1C of FIG. 3C, in which the inner rising portion (121c) and the outer rising portion (122c) are formed symmetrically in this way, satisfies the above condition X.
Further, in this embodiment, both the inner rising portion 121c and the outer rising portion 122c are deformed from the L-shaped body 121c ", 122c" arranged at the lower left and upper right of any position located on the bisector z as described above. Therefore, the above condition Y is also satisfied.
Further, in this aspect, since the second finding is taken into consideration, when a load weight acts on the vertically-roofed roof plate 1C, the inner rising portion 121c does not exert a tensile stress on the face plate portion 11 side on the outer side thereof. Shows the effect of

In the schematic diagram shown in FIG. 4A, the inner rising portion 121d is exactly the same as the inner rising portion 121c in FIG. 3, so that the condition Y is satisfied and the second finding is taken into consideration. be.
On the other hand, the outer rising portion 122d is composed of a diagonal piece having a length D3 adjacent to the inner rising portion 121d and a horizontal piece having a length D4 located on the contact portion (13) side. Based on the findings, the vertically-roofed roof plate (4th embodiment) 1D shown in FIG. 4B is formed as an embodiment in which the rising pieces close to the contact portion (13) are horizontally arranged.
Since the total length L1 of the molded portion in this embodiment is D1 (= C1) + D2 (= C2) + D3 + D4, in order to satisfy the above condition X, the molded portion base is formed from the center line between the roof plates adjacent to each other in the horizontal direction. By setting the position of the contact portion 13 upward so that the sum L2 of the horizontal distance to the end (D6 = C1 + C2) and the vertical distance from the face plate portion 11 to the lower end of the contact portion 13 is L1 ≦ L2. The condition X can be satisfied.

As described above, the condition X and the condition Y may be appropriately set and molded, and the molded portion may be laid only by mounting means such as fitting or engagement, or the contact portion may be partially or wholly formed. It can also be laid in combination with seam welding.

The metal vertical roof plate 1 (fifth embodiment) shown in FIG. 5A is a surface decorative steel plate having a mounting portion on the side edge of the face plate portion 11, and the mounting portion is from the face plate portion 11 to the surface side. It is composed of a molded portion 12 formed in a raised shape and an abutting portion 13 located further outside the molded portion 12 and standing up to the surface side.
The molded portion 12 of the illustrated embodiment has an inner rising portion 121 that rises from the edge of the flat face plate portion 11 toward the surface portion, and a raised portion 121 that is located further outside the inner rising portion 121 and rises toward the face plate portion 11. The outer rising portion 122 is provided. More specifically, between the inner rising portion 121 and the outer rising portion 122, a drainage portion 123 that is recessed downward and an inclined surface portion 124 that rises in an inclined manner on the outside thereof are provided.

The molded portion 12 (inner rising portion 121 and outer rising portion 122) may be attached only by mounting means such as fitting, engaging, and seam welding with a holding member (not shown), or may be adjacent to each other in the left-right direction. The contact portions 13, 13 may be attached in combination with seam welding partially or entirely.

As shown in the left half of FIG. 5 (d), the length of the metal plate material forming the inner rising portion 121 is S1, and the horizontal distance from the base end of the inner rising portion to the lower end of the contact portion 13 is S2. In this vertically-roofed roof plate (fifth embodiment) 1, the length S1 of the metal plate material forming the inner rising portion 121 is slightly smaller than the horizontal distance S2 from the base end of the inner rising portion to the lower end of the abutting portion 13. Since it is formed small (S1 <S2), the above condition Y (S1 ≦ S2) is satisfied.

Further, as shown in the right half of FIG. 5D, the length of the inclined surface portion 124 is S3, the length of the lower surface of the outer rising portion 122 is S4, the length of the upper surface is S5, and the length of the contact portion 13. Is S6, the total length of the molded portion 12, that is, the length of the metal plate material forming the molded portion 12 is S1 + S3 + S4 + S5.

The above-mentioned FIGS. 5 (a) and 5 (d) show the laying state other than the end portion such as the eave tip, and the end portion is as shown in FIGS. 5 (b) and 5 (c). It will be in a state where it has been processed horizontally or vertically.

FIG. 5 (b) shows a state in which a part (inner rising portion 121) of the molded portion 12 of the vertically-roofed roof plate 1 is processed horizontally, and FIG. 5 (c) shows a state in which the molded portion 12 is further processed into a vertical shape. In FIG. 5B, S7 is the length of the metal plate material forming the inclined surface portion 124 and the outer rising portion 122, and S8 is shown in the same figure and FIG. 5C. It is the length obtained by adding the length of the contact portion 13 to it.
5 (b) and 5 (c) show the state at the end of the eaves and the like of the roof structure using the vertically-roofed roof plate 1, and the abutting portions 13 and 13 adjacent to each other in the lateral direction face each other. It only shows the non-welded state.

Therefore, the length (S1 + S3 + S4 + S5) of the metal plate material forming the molding portion 12 comes into contact with the horizontal distance S2 from the center line between the roof plates 1 and 1 adjacent in the lateral direction to the base end of the molding portion 12 and the face plate portion 11. The condition X (L1 ≦ L2) can be satisfied by forming the portion 13 so as to be the same as or smaller than the sum (S2 + S7) of the vertical distance S7 to the lower end of the portion 13.

Then, in this vertically-roofed roof plate 1, the molded portion 12 can be laid only by mounting means such as fitting or engaging with a holding member or the like (not shown), or the contact portion 13 is partially or wholly welded. It can also be laid in combination with the above.
That is, in FIG. 5A, the abutting portions 13 and 13 of the adjacent vertical roof plates 1 and 1 show a state of facing each other and show a non-welded portion, but partially. Welding may be performed by seam welding or the like. At least after the processing shown in FIG. 5C, the vertical portion as shown on the left side of FIG. 8 is tilted horizontally, so that the contact portions 13 and 13 are welded to each other before the processing. Is desirable.
Further, in FIG. 5B, since the contact portions 13 and 13 are not welded to each other, the corresponding contact portions 13 and 13 are located in a separated state, but are welded as described above. If this is done in advance, the corresponding contact portions 13 and 13 will be located vertically.

The jig A used in FIG. 6A is provided with the above-mentioned horizontal processing, that is, a mechanism for sandwiching and crushing from the vertical direction, and the fixing members h, f, d arranged in the vertical direction. On the other hand, by rotating the slide rod j and the adjusting portions i and g, the inverted U-shaped upper movable body e is slid downward with respect to the plate-shaped lower fixed body c to make the inner rising portion 121 horizontal. To process. The state after this processing is shown in FIG. 5 (b).

The jig B used in FIG. 6B is provided with the above-mentioned vertical processing, that is, a mechanism for pinching and crushing from the left-right direction, and the left fixed body l is attached to the tip of the left arm of the main body m. Attached, the right movable body k is attached to the tip of the right arm of the main body m, and the right movable body k is slid from the right side to the left side by the slide rod n and the adjusting portion o to make the outer rising portion. Process 122 etc. vertically so as to press them from the side. The state after this processing is shown in FIG. 5 (c).

In the state immediately before the vertical processing, as shown in FIG. 5B, the outer rising portion 122 faces slightly downward, so that the product is folded when the processing is performed by sandwiching the product from the left-right direction as it is. May occur. Therefore, if the operator starts the operation while assistingly pulling the abutting portion 13 upward during the processing, the outer rising portion 122 can be deformed into an open shape and can be processed without causing folding.
Further, in any of the processing, since the bent portion (corner portion) in the molded portion 12 is formed into a bent shape (arc shape), horizontal processing or vertical processing can be performed without causing folding or the like. Was done.

The vertically-roofed roof plate 1 may lay the molded portion 12 only by mounting means such as fitting or engaging with a holding member (not shown), or the facing contact portions 13 and 13 may be partially or wholly laid. As already explained, it is possible to lay in combination with seam welding, but FIGS. 7 (a) and 7 (b) show the adjacent vertical roof plates 1 as in FIG. 5 (a). , 1 abutting portions 13, 13 face each other and are not welded, and FIGS. 7 (c) and 7 (d) show a state after processing into a horizontal shape as in FIG. 5 (b). 7 (e) and 7 (f) show the state after processing into a vertical shape as in FIG. 5 (c).

FIG. 8A shows a state in which the contact portions 13 and 13 facing each other are seam-welded after the horizontal processing and the vertical processing as described above (reference numeral 2 in the drawing is seam welding). FIG. 8 (b) shows a state in which the eaves portion is further horizontally tilted.
In FIG. 8, a large current is passed through the contact portions 13 and 13 of the overlapped metal plates, heated by the resistance heat generated here, and pressure is applied to continuously perform seam welding. In the figure, the seam-welded portion 2 starts from the eaves tip (left end) and is continuously performed.
In the figure, reference numerals 13 + 122 and 124 indicate a state after processing into a vertical shape as shown in FIGS. 7 (e) and 7 (f). Therefore, the portion is present at the tip of the eave shown on the left side of the figure, and only the contact portions 13 and 13 are located at the upper end on the right side of the figure showing the portion other than the tip of the eave.
FIG. 8B shows a state in which the eaves are tilted horizontally from the left side to the right side as described above from the front end representing the eaves tip, but after that, a member such as an eaves gutter may be attached as appropriate. At that time, since the eave tip of the exterior surface is formed horizontally, a member such as an eaves gutter can be easily attached. For example, in the seam welding, the eaves gutter may be integrally joined to the tip of the eaves.
