Abstract

PROBLEM TO BE SOLVED: To provide excellent drainage by integrally molding a desk material body along one side wall and by guiding water falling out of the edge of the deck material body outside the deck material with a drain. SOLUTION: A deck material 1 is formed by connecting an upper board 11 to a lower board 12 through a partition 13, provided with a deck material body 1A having a hollow part 14 and a drain 1B integrally molded along a side wall 15 of the deck material body 1A. This drain 1B is integrally molded with a bottom wall 16 extending from the lower end to the side of the side wall 15 and a drain wall 17 inclined upward from the front end of the bottom wall 16 in the direction away from the side wall 15. Moreover, an opening 20 of the drain 1B is narrowed by a cover 21 formed extending from the upper end of the side wall 15 toward the upper end of the drain wall 17. Thus, garbage scattered on the upper face of the desk material body is prevented from flowing into the drain by wind or running rain water.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a deck material used for a floor plate of a balcony or the like.

[0002]

2. Description of the Related Art A conventional deck material, as shown in FIG.
The deck material main body 1 is mounted on a foundation 103 such as joists suspended and fixed between the outer wall surface of the building 101 and the front beam 102 of the balcony.
04 is laid, and the front edge of the deck material main body 104 and the front beam 1
A gap 105 between the front beam 102 and the gap 02 is covered with a cover (blind part) 106 formed on the front beam 102. Also, on the lower side of the cover 106, the deck material main body 1
A drain groove 108 is provided so that rainwater and the like entering through the gap 107 between the cover member 04 and the cover 106 does not leak downstairs from the joint portion between the deck material and the front beam 102.
Rainwater and the like flowing into 08 flow into drainage grooves (not shown) provided in the side beams 109 along both side surfaces of the deck material,
The water is drained through a vertical gutter connected to this drain. In addition, the cover 106 is provided with a drain 1
I try not to get into 08.

[0003]

However, in the conventional deck material, as described above, the deck material main body 104 and the drain groove 108 are composed of different members, and the foundation 10 is made of these materials.
Must be fixed separately on 3. Therefore, there is a problem that the construction man-hours are required, workability is poor, and the number of parts is large, so that the material cost is increased.

Further, this deck material is the deck material main body 10
4 through the gap 107 between the cover 106 and the deck material body 10
Although the drain water 108 receives rainwater or the like that tends to flow down below 4, it does not leak downstairs, but a gap 110 is formed between the deck material main body 104 and the drain groove 108 depending on the skill level of the contractor. This gap 110
There is a risk of water leaking downstairs from the front of the balcony via.

The present invention has been made under the above circumstances, and provides a deck material having a small number of parts, excellent workability, no water leakage at the front of the balcony, and excellent drainage performance. Is an issue.

[0006]

DISCLOSURE OF THE INVENTION A deck material according to the present invention is integrally formed along one side wall of a deck material main body, and a drain groove for guiding water flowing out from the edge of the deck material main body to the outside of the deck material. It is characterized by having.

The deck material main body may be integral as a whole, but it may be of a structure in which it is divided into a plurality of divided bodies in the width direction and the divided bodies are integrally connected. Further, the drain grooves may be provided not only along one side edge of the deck material main body but also along both side edges.

With the above structure, the rainwater that has fallen on the upper surface of the deck material body flows down from the front edge of the deck material body into the drainage groove, flows along the drainage groove to the end portion of the deck material, and the drainage thereof is performed. Drains from the end of the groove.

[0009]

FIG. 1 shows an embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 is a side view of an example of a deck material according to the present invention.

The deck material 1 illustrated in FIG. 1 is a top plate 1.
1 and the lower plate 12 are connected by a partition wall 13,
Further, the deck material main body 1A having the hollow portion 14 is provided, and the drain groove 1B integrally formed along the side wall 15 is provided at the front end portion of the deck material main body.

The drain groove 1B integrally includes a bottom wall 16 extending laterally from the lower end of the side wall 15 and a drain wall 17 inclined upward in a direction away from the side wall 15 from the front end portion of the bottom wall. are doing. Because the drainage wall 17 is inclined,
As will be described later, the inflow of water from the upper surface of the deck material main body and the upper surface of the front beam of the balcony is facilitated. Preferably, an extension portion 18 and a rising portion 19 that extend in a direction away from the upper end portion of the side wall 15 are provided at the upper end portion of the drainage wall 17. When these are installed, drainage gutter 1 from the upper surface of the deck material main body and the upper surface of the front beam of the balcony.
The overflow of water flowing toward B is prevented. Further, the opening 20 of the drainage groove 1 </ b> B is formed so as to extend from the upper end of the side wall 15 toward the upper end of the drainage wall 17.
Narrowed by 1. As a result, in the drainage groove 1B,
It is possible to prevent dust and the like scattered on the upper surface of the deck material main body 1A from entering by wind or flowing rainwater.

As illustrated in FIG. 1, the deck material 1 may have a structure in which divided bodies which are divided in the width direction (the left-right direction in FIG. 1) are connected, or one side end of the deck material to the other It may be an integral structure that continues to the end.

In the preferred embodiment, a drain groove is also formed integrally with the rear portion of the deck material 1 along the rear side wall 17 'to guide the water flowing down from the rear edge of the deck material body 1A' to the outside of the deck material. It is equipped with 1B '. The opening 20 'of the drain groove 1B' is narrowed by the cover 21 '.

When the deck material 1 having the above-mentioned structure is used as the floor board of the balcony shown in FIG. 2, rain falling on the upper surface of the balcony deck due to the above-mentioned structure causes the edge of the deck material main body 1A of the deck material 1 to end. Flows into the drain 1B. At this time, since the drainage groove 1B and the deck material main body 1A are integrally formed without a seam, unlike the conventional case, rainwater or the like does not leak from the seam portion.

[0015]

Since the deck material according to the present invention is constructed as described above, since there is no joint between the deck material body and the drainage groove, rainwater and the like will not leak downstairs. . Further, since the number of parts is small, the manufacturing cost can be reduced, and the number of construction steps is small, so that anyone can easily perform the construction.
