Description

[Detailed Description of the Invention] The present invention consists of folding one of the left and right lateral sides of a flat rectangular plate with an opening to the back side and the other side to the front side, and
The present invention relates to an architectural wall board that is constructed by folding one of the upper and lower sides, including the left and right side folded sides, to the front side and the other side to the back side.

Roofing panels representative of such architectural wall panels are, for example, No. 11
As shown in the figure, both left and right folded pieces I of the flat rectangular plate
Conventional construction made of a flat plate 1 formed by cutting off the four corners outside the folding lines a and b of A and IB and outside the folding lines C and d of both the upper and lower folded pieces IC and ID Compared to other roof panels, this roof panel does not create gaps at the joints between adjacent roof panels due to machining errors, and is superior in terms of preventing rain leakage from the joints.

That is, in conventional roof panels, because the four corner portions are cut off, as shown in FIG. Between the overlapping surfaces of the lower folded piece ID of the board and the lower folded piece 1D' of the other roof board, there is a gap 4' that allows linear communication between the attic and the outside due to cutting and folding errors, etc. Since this structure is easy to form, there is a drawback that rainwater can easily enter the back side of the roof through this gap 4' during construction. Although there is a gap 4 at the lower end of the joint between adjacent roof plates that communicates the attic with the outside, within this gap 4, the lower folding piece ID,
The left and right folded pieces IB and IA' of both roof plates, which have been folded back together with ID', bend the gap 4 into an S-shape, and the edges 1btla' of the left and right folded pieces IA' Since the S-shaped gap 4 is separated by contacting the inner surface of the folded part of the IB, it is possible to prevent rainwater from entering the back side of the roof through the gap 4.

However, in architectural wall boards such as roof boards to which the present invention is applied, when the upper and lower sides are folded back, both the left and right folded pieces IA and IB are folded back again, so that the left and right folded pieces IA, IB and the 1 part of the flat plate that overlaps with it are closely polymerized at the folded parts of both the upper and lower folded pieces IC and ID, and as a result, there is a gap between the left and right folded pieces IA and IB and the flat plate part that overlaps with them. , left and right folded pieces lB of adjacent boards
Due to construction issues, it is difficult to form an appropriate gap for inserting the left and right folded pieces IA, IB', IB, and IA', and it is difficult to securely and accurately connect the left and right folded pieces IA, IB', IB, and IA'. There's a problem.

In view of the above, an object of the present invention is to make it possible to securely, accurately, and efficiently lock and connect adjacent architectural wall panels by simple structural improvements.

The characteristic structure of the present invention, which is a distant relative of the above object, is as follows:
Fold one of the left and right lateral sides of a single flat rectangular plate to the back side and the other to the front side, and fold one of the top and bottom sides, including the left and right lateral folded sides. In an architectural wall board constructed by folding one side to the front side and the other side to the back side, one side folding piece is folded on the folding line of the upper folding piece of the flat rectangular plate and is folded back to the back side. Folding each of the lateral folding pieces along the folding line of the upper folding piece at a position outside the line and a position inside the folding line of the other lateral folding piece that is folded back toward the surface side. A protrusion having a length equal to or approximately equal to the width and an extending groove having a length at least twice the length of the protrusion are separately formed, and the lower side is folded. On the folding line of the piece, at a position inside the folding line of one of the side folding pieces that is folded back to the back side, and at a position outside the folding line of the folding piece that is folded back to the front side, respectively. Along the fold line of the lower fold piece,
an extending protrusion having a length that is at least twice the folding width of each of the side folding pieces; and a concave line having a length that is equal to or approximately equal to the folding width of each of the side folding pieces. This configuration provides the following effects.

In other words, each side of the flat rectangular plate has the protruding stripes, the grooved stripes, the extending grooved stripes, and the extending protruding stripes on the folding line and along the line. Not only does it serve as a guide when folding the sides, it also makes it easier to construct the folded pieces as specified.Also, when locking the left and right folded pieces of adjacent wall panels on the left and right, the extension of one roof plate With the concave strips of the other roof plate fitted into the protruding strips, and the protrusions of one roof plate fitted into the protruding grooves of the other roof panel, both roof panels are separated from side to side. By sliding the protruding strips and the grooved strips as guides, the folded pieces can be reliably and smoothly locked together in the desired state without misalignment, improving work efficiency. Moreover, the intrusion of rainwater at the joint between adjacent roof panels can be prevented by the folded edges coming into contact with the folded parts.

Hereinafter, an embodiment of the present invention will be described based on the drawings.It is rectangular, and the left and right sides of the left and right side objects are placed on the left and right sides of the left and right objects that are adjacent to each other on the same contour line. It is laid on the roof base 3 in a state in which the lower side of the upper one overlaps with the upper side of the adjacent lower one in a state of being overlapped and deviated in the left-right direction, and each side side A roof board (an example of an architectural wall board) is provided with folded pieces for locking and connecting to left and right and upper and lower adjacent objects, as shown in FIGS. 2 to 4. ,
Fold the left and right sides of one flat rectangular plate 1 to the back and front sides, respectively, and fold back the left and right side pieces IA,
The top and bottom sides, including 1B, are folded back to the front and back sides, respectively.

In this embodiment, on the folding line C of the upper folding piece 1C, along the folding line C, at a position outside the folding line a of the left and right side folding pieces IA, the left and right sides are On the folding line d of the flat plate 1 part and the lower folding piece ID corresponding to the overlapping part when folding the parts, along the folding line d,
At the position inside the folding line a of the left and right side folding pieces IA,
Projections 2A and 2C are formed in a bulging shape on the left and right parts of the flat plate 1 corresponding to the overlapping parts when folding back the side parts, respectively, and the folding line is formed on the folding line C of the upper folding piece IC. C, at a position inside the folding line d of the left and right other side folding pieces IB, the flat plate 1 portion corresponding to the overlapping part when folding the left and right other side sides, and the folding line d of the lower side folding piece ID. At the top, along the folding line d, fold the other left and right folding pieces 1
Concave portions 2B and 2D are formed in a bulging shape at a position outside the folding line B at a portion of the flat plate 1 corresponding to the overlapping portion when folding the left and right sides, respectively.

Note that the protruding strip 2A on the folding line C and the grooved strip 2D on the folding piece d are formed to have a length equal to the folding width of the left and right folding pieces IA and IB. The portion 2B and the protruding portion 2C on the folding line d are connected to the left and right folding pieces IA, I.
It is slightly longer than twice the folded width of B.

According to the above configuration, at the lower end of the seam of adjacent roof plates in the left-right direction, there is a space between the overlapping surfaces of the lower folded piece ID' of the other side roof plate A' and the lower folded piece ID of the one side roof plate A. , there is a gap 4 that communicates the attic with the outside, and within this gap 4, there are the left and right side folded pieces 1A' that are folded back together with the lower folded pieces 1D' of the other side roof plate A'. , the lower folded piece 1D of the one-side roof board A and the left and right folded pieces 1B that are folded back again form the gap 4 in an S-shape, and the end edges 1a', lb The S-shaped gap 4 is separated by contacting the folded portions of the other folded pieces iB' and IA'.
Rainwater can be prevented from entering the back side of the roof through this gap 4.

Further, the grooved portion 2B and the protruding portion 2C on the inner side of the folding lines a and b are slightly longer than twice the folding width of the left and right side folded pieces IA and IB, thereby forming the left and right side folded pieces IA.

Since it extends inward from the edge of IB, the left and right side folded pieces IA and 1B' of adjacent roof panels A and A' on the left and right sides
