Description

[Detailed description of the invention] This invention relates to a metal plated roof structure.

The seam part of the conventional Kinpo roof plate is the upper seam 1 as shown in Figure 1.
I am engaging the lower goby 2.

The thickness of the metal roof plate 4 is about three times the thickness of the metal roof plate 4, and the thickness of the metal roof plate 4 is 0.3 mm to 0.5 mm, so the bulge during processing is at most 71 mm. .5 mm to 3
It's only a millimeter high. Other than ordinary houses, for example, temples, shrines, gymnasiums, etc. tend to have larger floor areas. If the roof of a building with such a large area has a low roof plate, it will not have any weight. However, on expensive copper plated roofs, the appearance of the seams gives a beautiful impression.

For those with a large roof area, the copper plate roof of a serika also has the disadvantage of being difficult to find.

Therefore, when it comes to copper sheet roofing for these wide water-resistant roofs, it has become desirable to have high yields. However, as shown on the second page, if the mitsuke is made high, it will not look good unless the mitsuke 5 is made small (15 mm). If pressure is applied to the roof plate 6 from above after construction, the roof plate 6 or the plate 5 will be deformed, and the deformation will be different in size depending on #hPjr, so the plate arrangement line that should be orderly will become ugly and collapse. The problem was that it spoiled the beauty of Setsuka.

The present invention has been made to solve these problems, and involves forming step portions at regular intervals in the longitudinal direction of a horizontally placed rafter made of wood, metal, synthetic resin, etc. Use it as a rafter on the roof with the lower end facing toward the eaves, and use roof boards on top of it, or directly place a roof board with a high rating, and align the board of the roof board with the step. The purpose of the present invention is to provide a thick metal plate roof structure which is characterized by forming and expressing a corner edge of 15 mm or more on the roof.

According to this invention having the above structure, steps are formed at regular intervals in the longitudinal direction on the upper surface of the rafter when it is placed horizontally, and the difference in height of the steps is equivalent to the height of the roof plate. Therefore, by using these rafters and installing the roof so that the height is in contact with the stepped part, the roof sheeting has the effect of not deforming even if the height is high. .

Embodiments of the present invention will be described below based on the drawings.

FIG. 3 and following FIG. 3 is a perspective view of a rafter according to the present invention. FIG. 4 is a sectional view taken along line AA in FIG. 3.

The rafter 7 is made of a square tube made of steel, with a band-shaped notch s8 formed in the longitudinal direction at the center of the upper surface width, and height difference portions 9.degree. 9 formed at regular intervals in the longitudinal direction of the upper surface. The difference in the step is configured to match the height of the roof plate, and forms a height difference of at least 15 mm.

As shown in FIG. 5, the rafter 7 is installed with the step part facing upward and the lower part of the step part facing toward the eaves, as in the case of normal rafters, and the step s9, A field board 10 with the same thickness as the height of the step 9 is stretched, and in the stepped portion 9, the lower field board 10' is in close contact with the end surface of the step, and the upper field board 10 is placed on the lower field board 101. Polymerize S.

A metal roofing board 12 having a height of a headboard 11 of at least 15 mm or more is installed on the sheathing board 10, 10' of the lever so that the headboard 11 corresponds to the step s9 of the rafter 7.

According to the present invention having the above configuration, since the stepped portions 9 are formed on the upper surface of the rafter 7 at regular intervals in the longitudinal direction, the roofing board 10 is stretched to the same thickness as the height of the stepped portions 9. Then, as shown in Figure 6, the thickness of the sheathing board 10 and the height of the mitsuke 11 of the roof shingle 12 will balance, and even if a roof board with a high sill is installed, the roof board itself and the mitsuke will not deform. effective.

Note that the present invention is not limited to the above configuration.

For example, the one shown in FIG.
4 are formed at intervals of one foot in the longitudinal direction, and the roof board 1
5 is thicker than the height of the stepped portion 14. Further, a marking 16 is formed at the rear end of the roof board 17. In this case, the thickness of the roof board is thin (but even if it is thick, there is no problem as long as the height of the stepped part of the rafter is the same as the height of the roof.

FIG. 8 shows a step part 20 formed by vertically fixing thin oblique plates 19 of wooden material, which are inclined in the longitudinal direction, to the upper side of a rectangular cylindrical rafter 18, with the thicker side facing forward. A metal roofing board 21 is directly installed on top of it without using roofing boards.
It is highly expressed.
