Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roof structure roofed using metal tiles.

Generally, metal tile roofs are constructed by fixing supporting materials at equal intervals along the slope of the roof, fixing both sides between the adjacent supporting materials, and sequentially covering metal tiles from below. It is constructed by fixing a cover material onto a supporting material so as to cover the connecting portion of the materials.
However, in conventional structures, the supporting material is made of wood, and the metal tiles and cover materials are fixed to the wood using nails while determining their positions on site, which results in extremely poor work efficiency and the need to hammer in nails. There was a problem that rainwater seeped into the wooden support material from the exposed parts, causing the support material to corrode.

The present invention was made to solve the problems of such conventional structures, and focuses on using a long metal plate with an inverted U-shaped cross section as a support material.
Cut and raised pieces are provided on this long metal material to fix the metal tiles and cover material at predetermined positions, and fixing holes corresponding to these cut and raised pieces are drilled in the metal tiles and cover material. to speed up roofing work,
At the same time, it is characterized by solving the problem of corrosion of supporting materials. Since the fixing hole of the cover material is provided at an upper position covered by the lower end of the upper cover material, it is possible to reliably cover the cover material from rain.

The present invention will be explained below with reference to illustrated embodiments.

Field boards 2, 2... perpendicular to the rafters 1 of the building and base material 3 laid on the field boards 2, 2... are fixed, and a supporting material 10 made of long metal material is fixed on the upper surface of this base structure part. The roof structure of the present invention consists of three elements: , metal tile material 20, and cover material 30.

The support member 10 has an elongated inverted U-shaped portion 11 formed by bending a metal material, and connecting edges 12, 12 bent outward from both lower ends of the inverted U-shaped portion 11. On both sides of the top 13 of the inverted U-shaped portion 11, cut and raised pieces for fixing metal tiles (hereinafter simply referred to as cut and raised pieces for tiles) 14 are provided at predetermined intervals, and the top 13 Cut and raised pieces for fixing the cover material (hereinafter simply referred to as cover cut and raised pieces) 15, 15 are provided at the center at the same required intervals. For example, the supporting members 10 are aligned with the rafters 1 and fixed at equal intervals along the inclination direction of the roof.

The metal tile material 20 is fixed on both sides to the adjacent supporting members 10, 10, and has arcuate raised portions 21, 21 on both side edges, and the top portion 12 of the supporting member 10 is further outside of the arcuate raised portions 21, 21. It has fixing parts 22, 22 having a curvature along the curvature of.

The fixing holes 23, 23 to be inserted into the tile cut and raised pieces 14, 14 of the support material 10 are fixed to the fixing portions 22, 22.
The metal tile material 20 is fixed to the support material 10 by inserting the tile cut and raised pieces 14, 14 into the fixing holes 23, 23 and then tilting them down as shown by the arrows in Fig. 3 and caulking them. It happens. An upper locking edge 24 and a lower locking edge 25 are bent at the upper and lower ends of the tile material 20, respectively. As the tile materials 20 are fixed, the upper and lower tile materials interlock with each other, forming a rainwater intrusion prevention space 26 between them.

The cover material 30 covers the connection portion between the metal tile material 20 and the support material 10 fixed as described above,
It has a semicircular cross-sectional shape, and is provided with inward U-shaped bent edges 31, 31 at both lower ends thereof.
The shape of the lower end of both sides of this cover material 30 is that of the metal tile material 2.
0, and its upper end becomes an insertion inclined portion 32, 32 formed by cutting off the U-shaped bent edges 31, 31. Insertion slope part 3
2 and 32 are U-shaped bent edges 3 of the upper cover material 30
1, 31, and at this time, the upper end of the lower cover material 30 is covered by the lower end of the upper cover material 30. Fixing holes 33, 3 corresponding to the cut and raised pieces 15, 15 for the cover of the support material 10
3 is provided at the portion covered by the upper cover material 30, that is, at the upper end portion of the cover material 30.

Therefore, according to the present roof structure having the above configuration, the tile cutting pieces 14, 1 of the supporting member 10 are fixed at equal intervals.
4, fix the metal tile material 20 as described above, then insert the fixing holes 33, 33 of the cover material 30 into the cut and raised pieces 15, 15 for the cover, and insert the cut and raised pieces as shown in the arrows in FIG. The roof can be roofed by folding and caulking as shown and continuing this operation while overlapping the lower end of the upper covering material 30 on the upper end of the lower covering material 30. Since the U-shaped bent edges 31, 31 at the lower end of the cover material 30 engage with the cover material 30 in a manner that wraps around the insertion inclined portions 32, 32 of the cover material 30 fixed below, each cover material The lower end portions of the cover material 30 are fixed by the insertion slope portions 32, 32 of the lower cover material 30, and the upper end portions are fixed by the cut and raised pieces 15, 15 for the cover, respectively, so that the cover material 30 is held in a stable state. becomes. Since the fixing holes 33, 33 at the upper end of each cover material 30 are covered by the lower end of the upper cover material 30, there is no risk of rainwater entering through the fixing holes 33, 33. Cover material 30
A rainwater infiltration prevention space 34 is provided between the metal tile material 20 and the metal tile material 20.
The formation of rainwater is also effective in ensuring that the rain does not go away.

Moreover, it goes without saying that the number of cut and raised pieces 14 and 15 for tiles and covers can be increased or decreased as appropriate, taking into consideration the reliability of fixation and work efficiency.

In summary, according to the present invention, the supporting material is a long material with an inverted U-shaped cross section, and the metal tile fixing pieces are provided on both sides of the top of this long metal material, and the cover material is fixed to the center of the top. A fixing hole is provided in the metal tile material and the roof to be inserted through each cut-and-rise piece, and the fixing hole of the cover material is covered by the lower end of the upper cover material. Therefore, a plurality of supporting members are installed parallel to the surface of the roof base material, a metal tile material is placed between adjacent supporting members, and a cut and raised piece is inserted through the fixing hole. The metal tile and cover material can be fixed to the support material by simply folding it down, placing the cover material on the top surface of the support material, and folding the cut and raised pieces that pass through the fixing holes, and no special techniques are required. But you can easily put a roof on it. Moreover, since the upper surface of the support material of a thatched roof is covered with a cover material, even if rain blows up from under the roof, it will not seep into the ceiling, making it extremely effective at blocking rain, especially for roofs with large areas. It is effective in construction.

In addition, by making the cross section of the support material into an inverted U shape, it is possible to bring it into surface contact with a part of the metal tile material or cover material, and the mounting strength of the metal tile material or cover material can be sufficiently increased. Even if a worker steps on the top surface of the cover material, it will not be crushed or damaged, and it can withstand long-term use and has high practical value.
