Abstract

PURPOSE: To improve th workability, by forming a drain groove to receive drain from the lower side, flowing down from the deck material body edge, along at least one side edge of the deck material body laid on a foundation to form a floor face. CONSTITUTION: In a deck material 1a, the drain groove 3a is arranged at a specified position by only fixing the deck material body 2a on a foundation 51. Since the deck body 2a and the drain groove 3a are formed as a unified body, there is no clearance between both materials and hence, the drain does not leak out. Accordingly, rainwater on the floor board 21 of the deck body 2a flows through the clearance between the other end 42 of a cover 4 installed along the building wall face 52 and a board-receiving part 28 and flows in the drain groove 3a and securely drained without leakage into the building 5 side. Since the drain groove 3a is coated with the cover 4, it is kept from refuse or the like. When necessary, the outside wall of the drain groove 3a is made elastic and deformable to press it on the building wall. In this way, water leakage is prevented and the deck can be easily constructed in a low cost.

The side wall portion 32 is placed on the foundation 51 so as to be substantially in close contact with the side surface of the overhang portion 53 provided along the wall surface 52 of the building 5, and the bottom plate portion is formed at the cutout portion 25 through the screw 29. 22
After fixing to the foundation 51, the drain 4
A floor of a balcony or terrace can be constructed by covering the upper surface of the opening 31 of the.

The cover 4 is formed by extrusion molding of a vinyl chloride resin like the deck material 1a, and as shown in FIG. 1, it has a projecting portion 53 provided along the wall surface 52 of the building 5. The upper surface is arranged so as to be covered by the one end 41 of the cover 4, and the other end 42 is covered with the extending portion 28 by fixing the one end 41 to the upper surface of the overhang portion 53.

That is, according to the deck material 1a, the drain groove 3a can be provided at a predetermined position only by fixing the deck material main body 2a on the foundation 51, so that the number of man-hours required for the balcony or terrace is small and simple. Can be built into. Further, since the deck material main body 2a and the drainage groove 3a are integrally formed, there is no space for drainage to leak from between the deck material main body 2a and the drainage groove 3a.

Therefore, the floor plate portion 2 of the deck material main body 2a
The rainwater, etc. that has fallen on the upper surface 1 of the cover 4 and the receiving plate 2
The water is surely drained without entering the drainage ditch 3a through the gap with respect to 8 and leaking to the building 5 side. Moreover, drainage ditch 3
Since a is covered with the cover 4, dust and the like will not enter the drainage groove 3.

The deck material 1a is shown in FIG.
As shown in (b), the deck material main body 2a may be fixed on the foundation 51 so that the drainage groove 3a comes to the front wall 6 side of the balcony or the balcony provided on the side opposite to the building 5.

A cylindrical body 37 is provided along the upper edge while being curved. Moreover,
The side wall 36 is thinner than the other parts and is elastically deformable.

That is, in this deck material 1f, even when the width of the balcony is smaller than the standard width of the deck material 1f, as shown in FIG. If the deck material 1f is set at a predetermined position of the foundation 51 while being pressed against the wall surface), the side wall 36 is elastically deformed and bent toward the deck material main body 2b side, without using spacers or cutting. However, the deck material main body 2b can be laid at a predetermined position without a gap.
That is, if the deck material 1f is used, not only the workability can be improved, but also the spacer or the like is not used, so that the cost can be reduced.

The deck material according to the present invention is not limited to the above embodiment. For example, the deck material body 2
a (2b) does not have the hollow portion 24, and the deck material main body 2a
(2b) may be a corrugated plate having a continuous U-shaped corrugated section. In addition, the drain 3a (3b, 3
c, 3d, 3e) does not use the end face 27 of the deck material main body 2a (2b) as one side wall, but the deck material main body 2a (2b).
It may be formed by integrally providing a member having a U-shaped cross section adjacent to the end face 27 of the.
