Abstract

PROBLEM TO BE SOLVED: To make it possible to reduce the bulk of a roof material during transportation in a unit roof material. SOLUTION: A unit roof material P is designed to place a plurality of same-sized boards one upon the other so that their respective vertical and horizontal sides may be placed in parallel where each of the boards 1 are placed one upon the other more than a half area and shifted one after another for a specified length in the vertical direction and staggered alternately in the vertical direction. In this case, for each of the upper and lower rectangular boards 1 piled up with the roof material P, a circumscribed rectangle A' is considered which is an overlapped part of the lower rectangular boards 1 and the other edge as a side. A point O is inside of the overlapped part and a cross point of a bisector of a vertical angle α, where the sides of the both rectangular boards 1 of the circumscribed rectangular A' cross, and another bisector of the vertically opposite angle γ of the vertical angle β of the circumscribed rectangle B'. The B' has a side 1 which is a side of the circumscribed rectangle of the vertical angle β and a side m which projects from the circumscribed rectangle A'. The upper and lower rectangles 1 are connected at the point O. Since the connecting point O is on the bisectors of the angles α and γ, the length of a and a, b and b are identical to each other as shown in the figure. Therefore, if one board 1 is rotated at 90 degrees against the other board 1, both boards will be one upon the other exactly.

[0017]

The operation of the first invention will be described with reference to FIG.
In the upper and lower unit roof pieces p, p, the midpoint O of the overlapping rectangular portion A (a portion surrounded by hatching, the same applies hereinafter) is a diagonal position of a diagonal line of the rectangular portion A. , The other unit roof piece p is connected to its connection point O
If they are rotated 180 degrees around the center, they will overlap exactly.

Therefore, in this unit roofing material, the upper and lower portions of the unit roof pieces p, p overlap each other at the midpoint O of the rectangular portion A, so that the above-described rotation operation is performed. .., The unit roof pieces p... Are exactly overlapped with each other, and are easy to carry.

The operation of the second invention will be described with reference to FIGS. 2 to 6. In FIG. 2, in the upper and lower unit roof pieces p, p, the connection point O of the overlapping rectangular portion A is
Since they are on the bisector of the angle α, the lengths of a and a in the figure are the same. Since it is also on a bisector, the lengths of b and b in the figure are the same. For this reason, if one unit roof piece p is rotated 90 degrees clockwise about its connection point O with respect to one unit roof piece p, FIG.
As shown in the figure, the overlapping portion becomes larger toward the right side, and the bulk becomes smaller.

The connection point O can also be obtained at the positions shown in FIGS. 4 to 6. In the case of FIG. 4, if the connection point O is rotated clockwise by 90 degrees, it overlaps to the left, and FIGS. In the case of, if it is rotated 90 degrees counterclockwise, it overlaps on the right side.

Therefore, in this unit roofing material, the upper and lower portions of the respective unit roof pieces p are connected at the point O, so that by performing the above-mentioned rotation operation, the respective unit roof pieces p are overlapped. The degree becomes large, the bulk becomes small, and it becomes easy to carry.

In the case of a unit roofing material having a projecting piece, the projecting piece projects in a rotated state. Even if it protrudes, the bulk is small when viewed from the roofing material in the construction state.

In the above invention, the unit roof piece p
Since the (rectangular plate 1) overlaps half or more in the vertical direction, the unit roof piece p is
It overlaps without gaps and covers the entire roof without gaps (see FIG. 15).

The operation of the third invention will be described with reference to FIG. 7. In the unit roof pieces p, p composed of the upper and lower rectangular plates 1, 1 with the projecting pieces 2, the circumscribed rectangle A 'of the overlapping portion.
Since the middle point O (portion surrounded by hatching) is located in the same manner as in the first invention, as shown in FIG. 8, one unit roof piece p is connected to the other unit roof piece p by the connection point O
If they are rotated 180 degrees around the center, they will overlap exactly.

Therefore, this unit roofing material is similarly small in bulk.

The operation of the fourth aspect of the present invention will be described with reference to FIGS. 9 and 10. In the unit roof pieces p, p composed of the rectangular plates 1, 1 with the protruding pieces 2, the overlapping part of the overlapping rectangle A ' At the connection point O, as in the second invention, the lengths a and a, and b and b are the same, and as shown in FIG. 10, both unit roof pieces p and p overlap.

Therefore, this unit roofing material is similarly small in bulk.

As can be understood from FIGS. 3 and 10, the rectangular plate 1 is rectangular, or a circumscribed rectangle having the other side of the rectangular plate 1 including the protruding piece 2 as a side (shown by a chain line in FIG. 11). If (rectangle) is a square, when the respective rectangular plates 1 are rotated and superimposed on each other, the planar shape thereof is also a square, and the volume is the smallest.

In the third and fourth aspects of the invention, the length of the protruding piece 2 is equal to or shorter than the vertical side of the rectangular plate 1 (within the vertical side length).
Each unit roof piece p is a rectangular plate 1
Are vertically shifted while being overlapped by half or more of the vertical length of the unit roof piece p, and the vertical side of the rectangular plate 1 of one unit roof piece p is projected sideways of the other unit roof side p.
To the position equal to or higher than the vertex, and vertically displaced in a staggered manner, so that the unit roof piece p overlaps without any gaps, and the entire roof without gaps Cover (Fig. 18, 1
9, 20, 21, 22).

In the fifth and sixth inventions, the third and fourth inventions
By the same operation as that of the invention of (1), one unit roof side p is exactly overlapped with the other unit roof side p, so that it is possible to reduce the bulk. In these two inventions,
Since the rectangular plates 1 of the unit roof pieces p overlap by half or more in the vertical direction, the unit roof pieces p overlap without any gap in the entire length of the overlapping portion in the vertical direction, and cover the entire roof without gaps.

[0031]

[Embodiment] As shown in FIG. 12 and FIG.
mm, short side: 240 mm, four metal rectangular plates 1 are shifted by 40 mm in the horizontal direction and stacked in the vertical direction by 160 mm, and each of the upper and lower rectangular plates 1, 1 is rotated by the blind rivet 10 at the point O of the second invention. The unit roof material P is manufactured by being connected as much as possible. At this time, the position of the rivet 10 is a point covered by the rectangular plate 1 above the two rectangular plates 1 and 1 to be riveted. If not covered, seal the rivet. The number of rectangular plates 1 (unit roof piece p) is determined in consideration of productivity and transportability in a factory, and the degree of overlap in the vertical direction and the degree of shift in the horizontal direction are determined in consideration of workability, waterproofness, and the like. Decide appropriately. This roofing material P is transported to the site by being superimposed as shown in FIG.

In order to roof the roof R shown in FIG. 14 with the unit roof material P, each rectangular plate 1 is placed in the state shown in FIG.

First, as shown in FIGS. 15 and 16, in the longitudinal direction, each unit roofing material P is
In the overlapping part, the upper surface side is the upper side, and the upper and lower rectangular roofs 1 that are in contact with the upper and lower unit roofing materials P have the same degree of overlap (two-thirds) with each rectangular plate of each unit roofing material P. To be constructed as On the other hand, in the horizontal direction, the side edge of each rectangular plate 1 of each unit roofing material P is fitted into the gap t between each rectangular plate 1 of the adjacent unit roofing material, and the abutting is performed on the side edge. In the figure, s is a screw hole.

The shingle R constructed as described above is constructed from the lower side (eave tip side), and the unit roof material P
Is fixed to a field material 3, a wood or the like with a nail c, a screw or the like. A waterproof seal and an adhesive can be interposed in each overlapping portion.

In the construction state shown in FIG. 15, since the upper rectangular plate 1 overlaps the upper surface of the lower one 1 in the longitudinal direction, rainwater flows smoothly downward. In addition, the overlap portion (see FIG. 17) of the roof material (rectangular plate) in the horizontal direction (see FIG. 17) is such that the side edge of each rectangular plate 1 fits into the gap t and abuts against the adjacent rectangular plate side edge. Thus, a waterproof effect can be obtained, and the prevention of water leakage due to superposition is further improved.

In the above embodiment, a simple rectangular plate 1 was used.
As shown in FIGS. 18 and 20, a unit roofing material P in which a protruding piece 2 having a shape symmetrical with respect to the center line thereof is provided on one side of the rectangular plate 1 is similarly connected by a blind rivet 10. When the roof is laid, the appearance of the planar shape is changed by the protruding pieces 2 as shown in FIGS. The protrusion 2 is not limited to the one shown in the figure.

In the embodiment having the projecting piece 2, the vertical overlapping degree of the unit roof piece p is set to be not less than half of the longitudinal direction of the rectangular plate 1, but as shown in FIG. The vertical length of the rectangular plate 1 is within the length of the rectangular plate 1, the degree of overlap is at least half of the length obtained by adding the length of the protruding piece 2, and the vertical side of the rectangular plate 1 of one unit roof piece p is the other. As described above, no gap is generated in the overlapping portion as described above, and the effect of the present invention can be obtained.

It is needless to say that the rotary connecting means is not limited to the blind rivet 10.
