Description

[Detailed description of the invention] This invention relates to roofs.

Conventionally, when a roof base material is laid on top of a field board, there has been a problem in that the roof base material is damaged by nailing, which causes rain to build up.

Furthermore, when tiles are nailed and fixed onto the roof base material, there is a problem in that this also causes damage to the roof base material.

Another problem was that the roof tiles were easily corroded by rainwater.

Therefore, an object of the present invention is to provide a roof that can prevent deterioration of waterproof performance due to nailing of the base material.

A second object of the invention is to provide a roof that can further alleviate deterioration of waterproof performance due to nailing of tiles and prevent corrosion of tiles.

An embodiment of the invention will be described with reference to FIGS. 1 and 2.

That is, in this roof, the roof base materials 3 laid on the roofing board 2 fixed on the top surface of the rafters 1 are folded back toward the top side at the creases along the gable direction at positions at appropriate intervals in the girder direction, and are folded slightly wide from the creases. A triple folded part is provided by folding back to the upper surface side at a separated fold, and the middle layer part and lower layer part of this triple folded part are fixed to the roofing board 2 with nails 4.

A tiling 5 along the row direction is arranged on the upper surface of the base material 3, and the tile 5 is fixed to the shedding board 2 with nails 6 from above the triple folded part of the base material 3.

Explain the construction method.

A roof base material 3 is laid on the upper surface of the roofing board 2 in the direction of the rows, that is, from the left side to the right side in the figure.

The direction from the left side to the right side is defined as the forward direction, and the roof base material 3 is folded in the opposite direction during the forward laying process, a nail 4 is driven into the folded part, and the roof base material 3 is folded back in the forward direction to cover the upper surface of the nail 4.

By repeating these steps, the roof base material 3 is nailed to the roof board 2 as shown in Figure 1, and then the tiles 5 are placed on the roof base material 3 as shown in Figure 2. Then, nails 6 are driven from above the folded part of the roof base material 3 to fix the tiles 5.

As a result, since the upper surface of the nail 4 is covered by the forward folded portion which is the upper layer of the three folded portions of the roof base material 30, deterioration of waterproof performance due to nailing of the roof base material 3 can be avoided.

Also, since the nail 4 penetrates the middle layer part and the lower layer part of the triple folded part, the nail 4 penetrates the middle layer part and the lower layer part of the triple folded part, so the nail 4 penetrates the middle layer part and the lower part part of the triple folded part, so
The penetrating portion is less likely to break and spread, which also reduces the deterioration of waterproof performance.

When the tiles 5 are fixed with nails 6, waterproofing of the part where the nails 60 penetrate becomes a problem.

However, since the nail 6 is driven into the folded part of the base material 303, compared to the case where it is driven into a single layer of the base material 3,
The base material 3 is easily damaged, and the decrease in waterproofness at the penetration portion of the nail 6 is alleviated.

The same is true when the nail 6 is driven into a single layer of the base material 3, but the part where the nail 60 penetrates is held down by the tiles 5, so the waterproofness is lower than where only the base material 3 is nailed. There are fewer problems.

Therefore, by driving the nails 6 into the triple folded portion in this way, certain degree of waterproofness can be obtained.

Since the roof tiles 5 are still nailed to the folded part of the base material 303, a gap 7 is created between the roof tiles 5 and the roof base material 30, resulting in good drainage (and corrosion of the tiles 5 due to rainwater). Prevented.

As described above, the roof of the present invention has folds that are folded toward the upper side at folds along the gable direction at appropriate intervals in the row direction of the roof base material laid on the roof board, and are folded at folds slightly width apart from the folds. A triple folded portion is formed by folding back to the top side again, and the middle layer and lower layer portions of this triple folded portion are nailed to the roofing board, so the triple folding of the base material is The top surface of the nail is covered by the upper layer of the overlapping part, and the nail penetrates through the middle layer and the lower layer, so the base material is difficult to tear, and this prevents deterioration of waterproof performance due to nailing of the roof base material. be done.

In the second invention, the tiles are nailed onto the triple folded part of the roof base material, so the nails will penetrate the roof base material in three layers. The roof base material is less likely to tear, and the decline in waterproof performance caused by fixing tiles with nails is also alleviated.

In addition, gaps are created between the tile tiles and the roof base material between adjacent folded parts, resulting in good drainage, which has the effect of preventing the tiles from corroding due to rainwater.

Claims (1)

[Scope of Claims] 1. Fold the roofing material laid on the roofing board at appropriate intervals in the direction of the girder, fold it back toward the upper surface at a crease along the gable direction, and then fold it back toward the upper surface at a crease a little width away from the crease. The roof is provided with a triple folded part formed by folding back, and the middle layer part and the lower layer part of the triple folded part are fixed to the roof board with nails. 2. At appropriate intervals in the row direction of the roof base material laid on the roof board, fold it back to the top side at the crease along the gable direction, and then fold it back to the top side again at the 9th fold, which is a little width away from the above crease. 3 A triple folded part is provided, the middle layer part and the lower layer part of this triple folded part are nailed to the roofing board, and tiles are arranged along the girder direction on the base material. The roof is nailed to the roofing board from above the triple folded portion.
