DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof sheet laid on a veranda, and more particularly to a small-sized veranda.

[0002]

2. Description of the Related Art A synthetic polymer roofing sheet is laid on the roof of a reinforced concrete building for waterproofing. The synthetic polymer roofing sheet is made of JIS
4A is a homogeneous sheet and a composite sheet obtained by combining the same with a base cloth and the like, and a flat sheet having a width of 350 mm to 500 mm is used as shown in FIG.
As shown by, the parts are subdivided into 24 parts (a) to (c) so as to correspond to each part of the laying position.

In particular, at the corners, the PVC material of the corner member shown in FIG. 5A, the corner member shown in FIG. 5B or the corner member shown in FIG. 6A, and the corner member shown in FIG. The molded product is thermally bonded to the outer corner and the inner corner of the waterproof sheet.

[0004]

The construction of the above-mentioned conventional waterproof sheet is a large-scale area on the roof of a building or the like.
In recent years, small-sized verandas have been increasingly built in single-family private homes, and small-sized verandas have been built in apartments and the like for each room.

[0005] The veranda having a small area also needs to be waterproofed, and if the same waterproofing construction as that of the conventional large-scale area is adopted, the number of parts is extremely large. There are many work parts to be bonded, and the construction time and construction cost are large.

[0006] Further, the large number of parts means that the number of parts to be bonded increases, and when the number of parts to be bonded becomes large, the number of locations where water leakage occurs increases with the passage of time, and there is a problem that the parts need to be repaired.

SUMMARY OF THE INVENTION An object of the present invention is to provide a veranda waterproof sheet that can be constructed in a short time at a low cost by using a waterproof sheet unitized with a very small number of parts on a veranda having a small area.

[0008]

The gist of the present invention to achieve the above object is to provide a synthetic polymer waterproof sheet laid on a veranda, which has a square bottom surface and a right angle of 2 mm. It has two left and right symmetrical first side wall members each having a side surface raised from a side, a rectangular bottom surface, a side surface raised from two perpendicular sides of the bottom surface, and a drain groove on the bottom surface. The first side wall member comprises two second side wall members having a left-right symmetrical shape facing the first side wall member, a rectangular bottom surface, and a side surface rising from one side in the longitudinal direction of the bottom surface. A pair of left and right intermediate side wall members connected to both sides of the first side wall member and the second side wall member facing the two side wall members;
Combination with a flat sheet member that fills the central space surrounded by the side wall member and the intermediate side wall member,
The first side wall member, the second side wall member, and the intermediate side wall member are formed and processed.

[0009]

According to the above construction, the first side wall member, the second side wall member, and the intermediate side wall member are formed in advance, and all or a part of these and flat sheet members are bonded in a factory or bonded on site to form a water. The present invention enables waterproofing of a veranda having a small number of bonded portions that causes leakage, and can be performed in a short time and at a low cost.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes the entire waterproof sheet of the present invention, and as specified in JIS A 6008, a synthetic vulcanized rubber system, a non-vulcanized rubber system, a vinyl chloride resin system, and an ethylene vinyl acetate resin system. It is made of polymer sheet. Note that, depending on the forming method, a composite sheet obtained by combining a base cloth or the like may be used.

The parts of the waterproof sheet 1 include two first side wall members 2 having a left-right symmetrical shape including a square bottom surface 3 and side surfaces 4 rising from two right sides of the bottom surface 3.
a, 2b, a rectangular bottom surface 7, a side surface 8 rising from two perpendicular sides of the bottom surface 7, and a drain groove 9 (a drain hole 10 is formed in one of the drain grooves 9). ), Two left and right symmetrical second side wall members 6a and 6b facing the first side wall members 2a and 2b, and a rectangular bottom surface 1
3 and a pair of left and right intermediate side wall members 12 a, each of which includes a side surface 14 raised from one side in the longitudinal direction of the bottom surface 13.
12b and a combination of a flat sheet member 11 filling a central space surrounded by the first side wall members 2a and 2b, the second side wall members 6a and 6b, and the intermediate side wall members 12a and 12b.

The first side wall members 2a and 2b, the second side wall members 6a and 6b, and the intermediate side wall members 12a and 12b are formed. This molding process may be injection molding, but vacuum molding is desirable in view of mold costs. Note that a composite sheet obtained by combining a base cloth and the like cannot be injection-molded or vacuum-molded, but can be molded by hot press molding.

An L-shaped step 5 is formed at the upper end of each of the side surfaces 4, 8, 14 of the first side wall members 2a, 2b, the second side wall members 6a, 6b and the intermediate side wall members 12a, 12b. The formation of the step 5 is not necessarily limited, and may be straight. The L-shaped stepped portion 5 functions as a water stopping function when water flows depending on the form of the construction place.

Since the present invention has the above-described structure, all of the first side wall members 2a and 2b, the second side wall members 6a and 6b, the intermediate side wall members 12a and 12b, and the flat sheet member 11, which are formed in advance, are formed. Alternatively, a part is adhered at a factory or on site so as to correspond to the dimensions of the veranda to be constructed, and unitized as shown in FIG.

[0015] As shown in FIG.
If necessary, the lap 15 is wrapped and sealed, and an L-shaped step 5 is formed at the upper end of each of the side surfaces 4, 8, and 14, and this step 5 is tacked or nailed to the inner wall of the veranda. It is desirable to stop and seal.

The waterproof sheet 1 of the present invention is basically formed by combining the first side wall members 2a and 2b, the second side wall members 6a and 6b, the intermediate side wall members 12a and 12b, and the seven convenient parts of the flat sheet member 11. But the area of the veranda is
When it is larger than the basic seven-part combination, another first side wall member 2a, 2b, second side wall member 6a, 6b,
It is possible to make use of the intermediate side wall members 12a and 12b and the flat sheet member 11 so as to cut them by an insufficient dimension and to supplement them as space members to cope with them.

[0017]

As described above, according to the present invention, two first side wall members having left and right symmetric shapes each having a rectangular bottom surface, side surfaces rising from two right sides of the rectangular bottom surface, and a rectangular bottom surface. , And a side surface raised from two perpendicular sides of the bottom surface,
A drain groove on the bottom surface, two second side wall members having a left-right symmetrical shape facing the first side wall member, a rectangular bottom surface, and a side surface rising from one side in a longitudinal direction of the bottom surface; A pair of left and right intermediate side wall members which are continuously provided on both sides of the first side wall member and the second side wall member facing each other, and a central portion surrounded by the first side wall member, the second side wall member, and the intermediate side wall member. Since the first side wall member, the second side wall member, and the intermediate side wall member are formed by a combination with a flat sheet member that fills the space, the structure is not limited to 7.
A tarpaulin with a very small number of parts is obtained,
All or some of these parts can be glued at the factory or glued on site to make them into a unit, making it possible to waterproof small-scale verandas with few bonding points that can cause water leakage at a short time and at low cost. Have the advantage of
