Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the structure of a decking material used for balconies, etc., which can be cut and used as a narrow decking material.

[Conventional technology and its problems]

A decking material A having small grooves 4 on its upper surface has been known from Japanese Utility Model Application Publication No. 52-70712 (this is shown in FIG. 6).

In the decking material A disclosed in Japanese Utility Model Publication No. 52-707125, rainwater flows through the small grooves 4, so that even if the decking material A has a wide width, drainage is good.

Furthermore, if the intermediate leg 3 is suspended next to the small groove 4, it is possible to make a narrow decking material A by cutting at the small groove 4, but this method is similar to the decking material A of Japanese Utility Model Publication No. 52-7071S. When cutting along the inner wall of the small groove 4 with a saw, the inner wall of the small groove 4 and the intermediate leg 3 are flush with each other in the vertical direction. There is a risk that the intermediate leg 3 may be damaged by the trowel, and there is a problem that the function of the intermediate leg 3 as a leg is impaired.

[Means to solve the problem]

The structure of the decking material of the present invention is that an L-shaped edge piece 6 with a vertical piece 9 at the tip hanging downward is provided at both ends of a wide surface plate part 1, and a horizontal piece 7 of the L-shaped edge piece 6 is provided. The leg 2 hangs downward from the extended base, and the lower surface of the U-shaped bent part 5 is made approximately at the same level as the lower end of the leg 2 between the legs 2 on both sides, and the U-shaped bent part 5 and at least one leg 2 are connected. An intermediate leg 3 is provided between the surface plate part 1 and
A small groove 4 is provided at a position away from the hanging portion of the intermediate leg 3 by the width of the horizontal piece 7 of the L-shaped edge piece 6 on the side opposite to the U-shaped bent part 5.

[Effect]

As described above, the present invention is to provide the small part 4 at a position away from the part where the intermediate leg 3 of the surface plate part 1 hangs by the width of the horizontal piece 7 of the L-shaped edge piece 6 on the opposite side to the U-shaped bent part 5. Therefore, when cutting along the inner wall of the small groove 4, the intermediate leg 3 is not damaged by the saw even if the saw is slightly tilted, and the function of the intermediate leg 3 as a leg is not impaired in any way. It is something.

Also, since the width of the horizontal piece 7 of the L-shaped edge piece 6 and the width from the intermediate leg 3 to the small groove 4 are equal, the cut end can have the same appearance as the L-shaped edge piece 6 after cutting. It is.

〔Example〕

L-shaped edge pieces 6 with vertical pieces 9 at the tips hanging downward are provided at both ends of the wide (for example, about 30 cm) surface plate part 1.

The legs 2 hang downward from the extending base of the horizontal piece 7 of this L-shaped edge piece 6.

An intermediate leg 3 is provided between the legs 2 on both sides.

Further, a U flatus curved portion 5 is provided in the center portion of the surface plate portion 1, and the lower surface of this U flatus curved portion 5 is approximately at the same level as the lower end of the leg 2.

An L-shaped edge piece 6 with a vertical piece 9 at the tip hanging downward is provided at both ends of the wide surface plate part 1, and a leg is formed downward from the extending base of the horizontal piece 7 of the L-shaped edge piece 6. 2 hanging down, legs 2 on both sides
A U flatus curved portion 5 is provided in between, so that the lower surface of the U flatus curved portion 5 is approximately at the same level as the lower end of the leg 2.

An intermediate leg 3 is provided between the U flatus flexure 5 and at least one leg 2.
A small groove 4 is provided at a position away from the part where the intermediate leg 3 of the surface plate part 1 hangs by the width of the horizontal piece 7 of the L-shaped piece 6 on the side opposite to the U flattened part 5.

In other words, the distance I from the small groove 4 to the intermediate leg 3 is approximately equal to the width of the horizontal piece 7 of the L-shaped edge piece 6.

In the embodiment shown in this drawing, the intermediate leg 3 and the U flattened portion 5 are provided at a width of 173 from both ends of the width of the surface plate portion 1.

Here, the upper edge of the small groove 4, the corner portion of the L-shaped edge piece 6, and the upper end of the U flattened portion 5 are all curved to prevent rounding.

Deck material A with the above structure is laid on a horizontal frame material such as a main building, and the 5 U flattened parts are fixed to the horizontal frame material using fixing devices such as screws, nails, bolts, nuts, etc. It is something to do.

By the way, even though the decking material A is wide, water can be drained quickly due to the presence of the small grooves 4.

On the other hand, when the decking material A needs to be cut according to the situation at the site, the cutting can be done neatly by cutting along the inner wall of the small groove 4 along the line XX in FIG.

In this case, even if the saw is slightly tilted when cutting, the intermediate leg 3 and the inner wall of the small groove 4 are separated by a distance approximately equal to the width of the horizontal piece 7 of the L-shaped edge piece 6, 3 will not be damaged.

Further, after cutting, the side portion of the deck material on the cut side is in the same state as the L-shaped edge piece 6, and the left and right side edges can be made symmetrical.

Note that the decking material A is a long material having the same cross-sectional shape at each portion in the longitudinal direction.

[Effect of idea]

In the present invention, as described above, L-shaped edge pieces are provided at both ends of the wide surface plate portion, with the vertical pieces at the tips hanging downward, and the extending bases of the horizontal pieces of the L-shaped edge pieces are provided. The legs are suspended downward from the base, and U flatus curves are provided between the legs on both sides so that the lower surface of the U flatus curves is approximately at the same level as the lower end of the legs, and the U flatus curves are located between at least one of the legs. An intermediate leg is provided on the surface plate, and a small groove is provided at a position opposite to the U flatus bend by the width of the horizontal piece of the L-shaped edge piece from the part where the intermediate leg of the surface plate part hangs, and is wide. Even if it is made of deck wood, water can be drained through small grooves.
It has good drainage, and when cutting the decking material for use, it can be cut with a chisel along the inner wall of the small groove (inner wall on the side of the U flatus curve) to make a narrower decking material. Of course, by providing a small groove at a position opposite to the U-flattened part by the width of the horizontal piece of the L-shaped edge piece from the part where the intermediate leg of the surface plate part hangs, it is possible to create a groove along the inner wall of the small groove. When cutting with a lever, even if the saw is slightly tilted, the intermediate leg will not be damaged by the saw, and the function of the intermediate leg as a leg will not be impaired in any way.

Furthermore, since the width of the horizontal piece of the L-shaped edge piece is equal to the width from the intermediate leg to the small groove, the cut end can have the same appearance as the L-shaped edge piece after cutting.
