Abstract

PURPOSE:To reduce man-power for execution of roof panels and to promote waterproof efficiency and strength by shifting joining lines between roof panels from the heights as division points of intersecting lines of the roof surfaces to arrange. CONSTITUTION:Joining lines 8 between roof panels 7 are shifted from the heights 4 as division points of intersecting lines 3 on the roof surfaces to arrange, and interior angles and between intersecting lines 3 are formed as they are at the heights of the roof panels 7. A pair of roof surfaces 2 showing triangles are constituted by connecting right-angled triangular panels 10 to both sides of pentagonal panels 9 of the center. While, a pair of roof surfaces 2 showing trapezoids are so constituted that every pair of rectangular panels 11, pentagonal panels 12 and triangular panels 13 are subsequently connected toward both sides longthwise from the center. According to the constitution, ridge angle sections of the roof surfaces can be formed by connecting only a minimum number of roof panels to be required, and any additional joining lines are not seen around the heights, so that waterproof efficiency and strength are promoted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof of a building such as a wooden house.

[0002]

2. Description of the Related Art As a conventional roof type in a building such as a wooden house, there is a type in which a roof surface having different roof flow directions is divided by three or more intersecting lines branched from one apex. As a typical type, for example, there is a hipped roof shown in FIG. 8 or a rectangular roof shown in FIG.

In the figure, reference numeral 20 designates a roof surface, which is divided by ridge lines (intersection lines) 21 forming a corner ridge.
Is formed by joining a plurality of roof panels 22 so as to be flush with each other. The broken lines in the figure indicate the roof panels.
22 shows the joining line 23 of 22. Therefore, conventionally, the roof panel 22 is generally arranged so that the joining line 23 passes through the apex 24 of the ridge 21 of the roof surface 20.

[0004]

However, in the above-mentioned conventional technique, the interior angle θ sandwiched between the ridgelines 21 of the roof surface 20 must be formed by joining the apex angle portions of the plurality of roof panels 22. Joining the roof panel 22 at the inner corner of the ridge 21 requires a great deal of construction work, and if there is an error in the apex angle of the roof panel 22, the error accumulates and the roof panel 22 cannot be installed at a predetermined position. There were cases.

In addition, conventionally, a vertex 24 at which the ridge line 21 intersects
It is not preferable from the viewpoints of waterproofness and strength of the roof because it has a structure in which more than necessary joint lines 23 intersect. In view of such circumstances, it is an object of the present invention to significantly reduce the time and effort required to construct a roof panel at a construction site and improve the waterproofness and strength of the roof.

[0006]

[Means for Solving the Problems] In order to achieve the above object,
The technical means taken by the present invention comprises a roof surface 2 having different roof flow directions divided by three or more intersection lines 3 branching from one apex 4, and the roof surface 2 has a plurality of roof panels 7. In the roof of the building constructed by joining the two in the same plane, the joining line 8 between the roof panels 7 is arranged so as to intersect the intersection line 3 of the roof surface 2 at a position displaced from the apex 4. There is a point.

[0007]

In the present invention, since the joining line 8 between the roof panels 7 is arranged at a position displaced from the apex 4 which is the branch point of the intersection 3 of the roof surface 2, the interior angles α, β between the intersections 3 are arranged. The roof panel
It can be configured as is with an apex angle of 7.

[0008]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention and shows a case where the present invention is applied to a so-called dormitory roof. This hipped roof 1 has four roof surfaces with different roof flow directions.
The roof surface 2 is divided into five ridgelines 3 in total. That is, in the case of the hipped roof 1, the three ridge lines 3
There are two vertices 4 at the top, where ridges 3 branch off. It has become.

In the present embodiment, each of the roof surfaces 2 is constructed by joining a plurality of roof panels 7 flush with each other, and furthermore, a joining line 8 between the roof panels 7 (broken line in FIG. 1). Are arranged so as to intersect the ridgeline 3 of the roof surface 2 at a position deviated from the apex 4. That is, of the four roof surfaces 2, a pair of triangular roof surfaces 2 is formed by joining right-angled triangular panels 10 to both sides of a central pentagonal panel 9, and the upper end of the pentagonal panel 9 is joined. The apex angle of is set so as to substantially coincide with the interior angle α sandwiched between the ridgelines 3 forming the corner ridge 6.

On the other hand, a pair of trapezoidal roof surfaces 2 are
It is configured by joining a pair of square panel 11, pentagonal panel 12 and triangular panel 13 in that order from the center toward both sides in the longitudinal direction, and the apex angle of the upper end of the pentagonal panel 12 is the large ridge 5. Ridge line 3 and corner building 6
It is set so as to substantially coincide with the interior angle β sandwiched between the ridgelines 3 forming the.

In this embodiment, the above-mentioned panels 9, 10, 11,
The joint line 8 of 12,13 is adapted to coincide with the roof flow direction of each roof surface 2 which they constitute. As shown in FIGS. 2 and 3, the roof panel 7 is mainly composed of a base plate 15 in which a rafter 14 is framed on the lower surface, and in this embodiment, a waterproof sheet 16 and a waterproof sheet 16 are provided on the upper surface of the base plate 15. Roof tiles 17 have been constructed in advance in factories. Therefore, each roof panel 7
Will be brought to the site in a state where it has been processed up to the roof, and it will be installed by lifting it with a crane etc. on the beam material of the main body of the building and the building support material (not shown).

According to this embodiment having the above structure, the joining line 8 of the roof panel 7 is arranged so as to intersect the ridgeline 3 at a position deviated from the apex 4 of the ridgeline 3, as shown by the diagonal lines in FIG. , Pentagonal panel 9 and 12
Since it is configured as it is at the apex angle of the roof surface, it is only necessary to join these three panels 9 and 12 along the ridgeline 3
It is possible to configure the ridge corner part of the roof panel, and it is possible to significantly reduce the time and effort required to construct the roof panel 7 at the construction site.

Further, according to the present embodiment, since the joining line 8 of the roof panel 7 other than the ridgeline 3 does not occur around the apex 4, the waterproofness and strength of the roof top can be improved. FIG. 4 shows a second embodiment of the present invention, in which the present invention is applied to a so-called rectangular roof. In this rectangular roof 18, all four roof surfaces 2 have a triangular shape, and these roof surfaces 2 are divided by four ridgelines 3 branching from one vertex 4 located at the center of the roof. Therefore, the rectangular roof 18 has a square cone shape, which corresponds to a case where the large ridges of the ridge roof 1 are integrated into one vertex 4.

Also in this embodiment, the joint line 8 of the roof panel 7 is arranged so as to intersect with the ridge line 3 at a position displaced from the apex 4 of the ridge line 3, and the same effect as that of the first embodiment can be obtained. Of course. Although the embodiment according to the present invention has been described above, the present invention can be applied not only to the basic roof type described above but also to a roof having a more complicated shape as shown in FIG. 5, for example.

Further, as shown in FIGS. 6 and 7, the joint lines 8 of the respective panels 9, 10, 11, 12, 13 may be arranged so as not to intersect with each other.
In this case, since the joining line 8 does not intersect even on the ridgeline 3, the waterproofness and strength of the roof can be further improved. Further, in the above embodiment, the case where all the intersections between the roof surfaces 2 are the ridges 3 has been described, but it is needless to say that the present invention can be applied to the case where the intersections are the valley lines.

[0016]

As described above, according to the present invention,
The joint line 8 between the roof panels 7 is arranged so as to be offset from the apex 4 which is the branch point of the intersection line 3 of the roof surface 2, and the interior angle α,
Since β is constructed as it is at the apex angle of the roof panel 7, only the minimum required number of joints of the roof panel 7 can be applied to the roof surface 2
It is possible to configure the ridge corner part of the roof panel, and it is possible to significantly reduce the time and effort required to construct the roof panel 7 at the construction site.

Further, since the unnecessary joining line 8 does not occur around the apex 4, the waterproofness and strength of the roof top can be improved.
