Description

Description: TECHNICAL FIELD The present invention relates to two types of triangular shaped metal roof plates and a roof construction method in which the roof plates are combined and thatched.

[Prior Art] As a combination of shaped roof tile metal roofing boards for roofing, one side of a method in which four sides of a rectangular metal sheet are goby-folded and the bent portions engage with each other. There are a thatched roof, a turtle shell mushroom and a thatched roof that are made into a rhombus shape.

[Problems to be Solved by the Invention] In the conventional construction method, one side end in the lateral direction is goby-folded upward, and the other side end is gotten-folded downward, and the metal sheets are engaged one after another. However, there is a problem in rain finish such as intrusion of rain from this connection portion or intrusion due to a capillary phenomenon. In addition, it is necessary to use a suspender or to combine it with many parts to make a completed roof, and an auxiliary member is required.

[Means for Solving the Problems] Therefore, in the present invention, two types of triangular roof plates are prepared in order to prevent rainwater from entering due to the connection between the roof plates, and a goby fold portion is provided on each hypotenuse. The goby folds of the equilateral triangle roof plate are formed by folding back upwards, and the goby folds of the inverted triangle roof plate are formed by folding back downwards. Engage and connect so that the goby fold of the triangular roof plate is on the upper surface. Then, a slight step is formed at the connecting portion in the lateral direction, and a large step is formed at the connecting portion of the upper and lower roof plates. By doing so, even if rainwater enters the goby portion, the rainwater flows down along the reverse hypotenuse of the inverted triangular roof plate, so that the rainwater cannot enter the roof side unless it flows backward.

Also in the construction, the regular triangular roof plate is engaged with the inverted triangular roof plate at the goby fold portion of the hypotenuse and is lifted and held in a wedge shape, so it suffices to fix only the inverted triangular roof, and Since auxiliary members such as connecting materials and suspensions are not required, the construction is simple and the cost is low.

EXAMPLES Next, the present invention will be described with reference to the examples shown in the drawings.

FIG. 1 shows an equilateral triangular roof plate A, in which the two hypotenuses are goby folds 1 and 2 which are folded upward with a slight width.
The bottom side is a U-shaped locking portion 3 that is bent downward.
There is. The top is semi-circular in shape and the edge is raised to the water stop side 4
The inside of the water blocking table 5 is bulged to the same height as the water blocking piece.

FIG. 2 shows an inverted triangular roof plate B, and the two hypotenuses are goby folds 6 and 7 which are folded back downward with a slight width, contrary to the hypotenuse of the equilateral triangular roof plate A. The top edge is curled upward to form the engaging portion 8, and then the top edge is further curled so as to be flipped upward and backward to prevent the water stop wall 9.
Then, after being sequentially folded back along the back surface of the water blocking wall and the upper surface of the engaging portion, it is bent backward to form a fixed piece 10, and the lower apex side is bent downward to form a falling piece 11. .

As shown in FIG. 9, the roofing procedure is such that an inverted triangular roof plate B is fitted between regular triangular roof plates A so that the goby folds 1, 2, 6, 7 of the hypotenuses of both sides are engaged with each other. Then, from the verge edge b on the eaves side a toward the ridge side c and on the opposite side of the verge edge sequentially, both roof plates are alternately connected and raised. Fixing the bottom fixing piece 10 of the inverted triangular roof plate B with nails and fixing it, and not fixing the equilateral triangular roof plate, the engagement part 3 on the bottom side and the goby fold part on both sides of the diagonal side of the roof plate are not fixed. It is held by the combination. In the case of triangle roofing as shown in FIG. 3, the upper and lower connection structures are the connection structure X between the bottom and top of the upper and lower equilateral triangular roof plates A, and the upper part is an equilateral triangular roof plate A. In the lower tier, the lower triangular roofing board B and the connecting structure Y between the bases, and the upper and lower tiers of the inverted triangular roofing board B
There are three types of connection structures of the connection structure Z at the top and bottom sides of each other, and the cross-sectional structures shown in FIGS. 4 to 6 are obtained.

FIG. 4 shows a connecting structure X portion of the equilateral triangular roofing plates A, and the locking portion 3 on the bottom side of the equilateral triangular roofing plates A has a water stop at the top of another equilateral triangular roofing plate A. It is only on the table 5. However, since the water stop 5 is raised further and the water stop pieces 4 are raised, the goby folds 6 and 7 of the adjoining inverted triangular roof plate B are located on both sides of the water stop 5. The enclosed space and the space viewed from below are obstructed by the raised water stop 5, so that rainwater is prevented from entering. In addition, since both roof plates A are adjacent triangular roof plates B on both sides and goby folds 1, 2, 6, 7 formed on the hypotenuse are engaged with each other, the roof plates firmly hold each other. No engagement is required at the upper and lower connections.

FIG. 5 shows a connecting structure Y portion of the bottom sides of a regular triangular roof plate A and an inverted triangular roof plate B.

The engaging portion 3 on the bottom side of the upper triangular roof plate A is engaged with the engaging portion 8 on the lower side of the lower triangular roof plate B.

FIG. 6 shows a connecting structure Z portion between the roof plates B having an inverted triangular shape.

Also in this case, the rising pieces 11 on the top of the upper inverted triangular roof plate B are not directly engaged with the locking portions 8 on the bottom side of the lower inverted triangular roof plate B. In either case, since the roof plates are firmly held by engaging with the goby folds on the hypotenuses of the two adjacent roof plates, the upper and lower roof plates need not be engaged with each other in terms of strength.

Next, a connection structure in a diamond roof in which the tops or bottoms of the equilateral triangular and inverse equilateral triangular roof plates A and B are connected in the upper and lower stages will be described with reference to FIGS. 7 to 8. FIG. 8 shows a sectional structure of a V portion where the tops are connected to each other. The rising piece 11 on the top of the upper inverted triangular roofing plate B is placed on the top of the lower regular triangular roofing plate A but not engaged.

The sectional structure of the W portion where the bases are connected to each other is similar to that shown in FIG.

The engaging portion 3 on the bottom side of the upper triangular roof plate A is engaged with the engaging portion 8 on the lower side of the lower inverted triangular roof plate B.

In these cases as well, in each roof plate, the goby folds on the hypotenuses of the two adjacent roof plates engage with each other and firmly hold each other.

[Effects of the Invention] Since the present invention is configured as described above, since the lateral connection of the roof plates is engaged at the goby folds of the hypotenuses, the equilateral triangular roof plates are formed on both sides of inverted triangles. Since the roof plate is lifted like a wedge and firmly held, the roof plate can be fixed by nailing only the inverted triangular roof plate, so the construction is simple, and the connection material and the hangings etc. Auxiliary parts are not required and the cost is low.

Since the inverted triangular roof plate is located on the upper surface of the engaging portion of the oblique side, rainwater flows down along the reverse oblique side of the inverted triangular roof plate in the arrow direction shown in FIGS. 3 and 7. There is no risk of lateral leakage into the attic.

Furthermore, a variety of roof surfaces can be created by combining triangular roofing plates, and a roof with a sense of hobbing can be created.
