Abstract

PURPOSE:To facilitate the execution of work by arranging equilateral-triangle- shaped roof sheathings and reversed-triangle-shaped roof sheathings alternately in the horizontal direction, and by engaging the split-folding sections of adjacent oblique sides with each other in order, to fix the upper sections of the reversed- triangle-shaped roof sheathings on battens. CONSTITUTION:The two oblique sides of an equilateral-triangleshaped roof sheathing A are folded back with upper slight widths, and split-folding sections 1, 2 are arranged. After that, the split-folding sections 6, 7 folded back with upper slight widths, of the two oblique sides of a reversed-triangle-shaped roof sheathing R are arranged. After that, sections between the roof sheathings A are sheathed with the roof sheathings B so that the split-folding sections 1, 2, 6, 7 of both the oblique sides may be engaged with each other and so that both the roof sheathings may be alternately jointed to each other to the side C of a ridge from a verge end (b) on the side (a) of an eaves in order and in the direction of a verge side on a counter side. Then, the fixing pieces 10 of the bottom sides of the roof sheathings B are fixed with nails, and the roof sheathings A are retained by engaging engaging-sections 3 with the adjacent split-folding sections.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to two types of triangularly formed metal roof panels and a roof construction method in which the roof panels are combined.

[Prior art 1] For roofing by combining molded tile-like metal roof sheets, there is a method in which the four sides of a rectangular metal sheet are folded in half, and the folded portions engage with each other. There are two types of roofs: tortoise-shell roofing, diamond-shaped roofing, and diamond-shaped roofing.

[Problems to be solved by the invention] The conventional construction method involves folding one side edge in the horizontal direction upward,
Since the metal plates are made by folding the other rPJ@ downward and engaging the folds one after another, there are problems with rainwater, such as rain entering through this connection or intrusion due to capillary action. . In addition, it requires hangers and can only be made into a complete roof by combining many parts, so auxiliary members are required.

[Means for Solving the Problems] Therefore, in order to prevent rainwater from entering through the joints between the roof panels, the present invention prepares two types of triangular roof panels, and provides a seam fold on each oblique side. However, the halves of the equilateral triangular roof plate are formed by folding upward, and the halves of the inverted triangular roof plate are formed by folding downward.
Both triangular roof panels are engaged and connected so that the folded portions of the inverted triangular roof panels are on the top surface. There is a slight difference in level between the horizontal connections, and a large difference in level between the upper and lower roof panels. By doing this, even if rainwater enters the seam, it will flow down along the inverted hypotenuse of the inverted triangular roof board, resulting in a structure in which rainwater cannot enter the back side of the roof unless it flows backwards.

In addition, during construction, the equilateral triangular roof plate engages with the inverted triangular roof plate at the folded part of the oblique side and is lifted and held in a wedge shape, so it is sufficient to fix only the inverted triangular roof plate. Further, since auxiliary members such as connecting materials and hangers are not required, construction is simple and cost is reduced.

[Example] Next, the present invention will be explained according to embodiments shown in the drawings.

Fig. 1 shows an equilateral triangular roof board A, and the two hypotenuses are folded parts 1 and 2 that are folded upward with a slight width.
The bottom side is a U-shaped locking part 3 that is not bent downward.
It is as follows. The top part has a semicircular edge raised to form a water stop piece 4.
There is a water stop table 5 whose inner side bulges to the same height as the water stop piece.

Fig. 2 shows an inverted triangular roof board B, and the two hypotenuses are folded downward with a slight width, opposite to the hypotenuses of the equilateral triangular roof board A. After the top side is curled upward to form the engaging part 8, it is further curled upward and backward to form an ice-stopping wall, and then sequentially along the back surface of the ice-stopping wall and the top surface of the engaging part. After being folded back, it is bent backward to form a fixed piece 10, and the lower apex side is bent downward to form a hanging piece 11.
It is as follows.

The roofing procedure is as shown in Fig. 9, in which an inverted triangular roof board B is placed between an equilateral triangular roof board A, and the halves 1, 2, and 6.7 of the oblique sides of both roof boards are engaged with each other. Then, from the verge end b of the eave side a, the roof is successively raised toward the ridge side C and the verge end on the opposite side, connecting both roof boards alternately. Fixed piece 10 at the bottom of the inverted triangular roof board B
are nailed and fixed, and the equilateral triangular roof plate is not fixed, but is held by engagement between the locking part 3 on the bottom side and the folded part on the oblique sides of the roof plates on both sides. In the case of triangular roofing as shown in Figure 3, the connection structure for the upper and lower tiers is a connection structure X between the bases and tops of the equilateral triangular roof plates A for the upper and lower tiers, and an equilateral triangular roof for the upper tier. There are three types of connection structures: a connection structure Y between the roof plate A and the bottom side of the roof plate B, which has an inverted triangular shape, and a connection structure Z between the top and bottom sides of the roof plates B, which have an inverted triangular shape on both the upper and lower levels. The cross-sectional structure is shown in FIGS. 4 to 6.

Figure 4 shows a connection structure X between equilateral triangular roof panels A, and the locking part 3 at the bottom of the equilateral triangular roof panel A is used to stop water at the top of another equilateral triangular roof panel A. It is only placed on table 5. However, since the water stop table 5 is raised one step higher and the water stop piece 4 is raised, rainwater is prevented from entering. In addition, both roof panels A have seam folds 1 and 2 formed on the oblique sides of the inverted triangular roof panels B on both sides, respectively.
, 6.7 Since the diagonal roof plates that are engaged with each other firmly hold each other, engagement at the upper and lower connecting portions is not necessary.

FIG. 5 shows a connection structure Y between the bases of an equilateral triangular roof panel A and an inverted triangular roof panel B.

A locking portion 3 at the bottom of the upper equilateral triangular roof plate A is engaged with an engaging portion 8 at the bottom of the lower inverted triangular roof plate B.

FIG. 6 shows a Z portion of the connection structure between the inverted triangular roof panels B.

Also in this case, the upright piece 11 at the top of the upper inverted triangular roof plate B does not directly engage with the locking portion 8 at the bottom of the lower inverted triangular roof plate B. In either case, since the roof panels are firmly held together by engaging with the folded portions of the oblique sides of the roof panels on both sides, there is no need for the connection between the upper and lower roof panels to engage with each other in terms of strength.

Next, a connection structure in Tiramid roofing in which the tops or bottoms of the equilateral triangular and inverted triangular roof panels A and B are connected to each other in the upper and lower stages will be described with reference to FIGS. 7 and 8. FIG. 8 shows the cross-sectional structure of the V portion where the tops connect. The upright piece 11 on the top of the upper inverted triangular roof board B only rests on the top of the lower equilateral triangular roof board A, but does not engage with it.

Further, the cross-sectional structure of the W portion where the bases connect to each other is the same as that shown in FIG.

A locking portion 3 at the bottom of the upper equilateral triangular roof plate A is engaged with an engaging portion 8 at the bottom of the lower inverted triangular roof plate B.

In these cases as well, each roof sheet is firmly held by the diagonally folded portions of the roof sheets on both sides engaging with each other.

[Effects of the Invention] Since the present invention is constructed as described above, the roof panels are connected in the horizontal direction by engaging each other at the diagonal folds, so that the roof panels in the shape of an equilateral triangle are connected to the inverted triangles on both sides. Because the shaped roof panels are hung like a wedge and held firmly, the roof panels can be fixed by simply nailing the inverted triangular shaped roof panels, making installation easy. No auxiliary parts are required and costs are reduced.

Since the engaging part of the hypotenuse is located on the upper surface of an inverted triangular roof plate, rainwater flows down along the inverted hypotenuse of the inverted triangular roof plate in the direction of the arrow shown in Figures 3 and 7. There is no risk of side leakage to the backside of the roof.

Furthermore, by combining triangular roof plates, it is possible to create a roof surface that is rich in variety, and it is also possible to create a roof that is rich in taste and has the feel of horizontal roofing.
