DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof portion, particularly a veranda of a detached house or the like, which is formed adjacent to a waterproof layer portion of a balcony or the like, and guides rainwater or the like flowing out of the waterproof layer portion to a drain hole. And a gutter member used for the same.

[0002]

2. Description of the Related Art When a living room or the like is formed in order to make effective use of a lower space such as a veranda or balcony, waterproof treatment is required as a measure against rainfall or the like. Then, rainwater or the like flowing through the waterproof surface is concentrated to the drain hole and discharged to the outside. By the way, the outflow of water to the drainage hole may be performed by forming a slight gradient on the waterproof surface and using this gradient. The formation requires a complicated tilting process, and the construction is also complicated. For this reason, conventionally, generally, a side groove is formed at an end portion of a veranda, a balcony, or the like, and rainwater or the like is caused to flow out of the waterproof layer portion into the side groove and then guided to a drain hole. In forming the gutter, measures were taken such as making a gradient using mortar or the like on the site, or forming a gradient by combining square timber, plywood, etc.However, this method depends on the skill of the individual worker. Therefore, there is a possibility that the stability of the work quality is lacking. Therefore, in place of such a manual gutter formation, a method of forming a molded member with a water gradient at an Arakaji factory or the like and connecting them at the site to form a gutter at a predetermined location is often used. I have. FIG. 5 is a view showing a gutter structure in such a conventional method. In the drawing, reference numeral 11 denotes an end-side groove member, which includes a bottom portion 11a, walls 11b, 11b rising at both end edges of the bottom portion 11a, and an abutment portion 11c. Reference numeral 21 denotes an inclined side groove member, which is a slope bottom 21a, and walls 21b, 21b rising on both end edges of the slope bottom 21a.
With Horizontal flanges 11d and 2d are provided at the upper ends of the wall portions of the end side groove member 11 and the inclined side groove member 21, respectively.
1c and L-shaped flanges 11e and 21d are provided, respectively, and are attached to a floor surface or a rising portion of a veranda, a balcony or the like via a counterpart member (not shown). In addition, 31 is a veranda, a waterproof layer part such as a balcony,
Reference numeral 41 denotes a rising part. The formation of the side groove connected to the waterproof layer portion 31 is performed by adding the inclined side groove member 2 to the above-described end side groove member 11.
Normally, a plurality of 1s are connected. For example,
The depth of the groove of the end side groove member 11 shown in FIG. 5, that is, the height of the wall portion 11b is 20 mm, and the starting end of the wall portion 21b (in the end side groove member 11) is connected to the inclined side groove member 21. The height of the contacting side (the right side in the figure) is 20 mm, and the height of the terminal end (the left side in the figure) is 40 mm. Therefore, the starting end of the inclined side groove member 21 has the same depth as the groove depth 40 mm of the terminal end. The other inclined side groove member having the above, and further the end side groove member are sequentially connected to form a side groove of a predetermined length.

[0003]

However, the above-mentioned prior art has a number of disadvantages caused by an increase in the number of parts. In other words, the length, gradient, etc. of the side grooves to be formed are variously varied depending on the shape and width of the veranda, balcony, etc.
To cope with this, it is necessary to prepare inclined side groove members of various sizes and shapes. In addition, since it is necessary to reverse the formation position of the L-shaped flange and the horizontal flange depending on the position of the drain hole, the types of the side groove members to be prepared are further increased, and complicated design work, complicated construction, This imposes an excessive burden on inventory management associated with various types of members, and a rise in costs associated therewith.

[0004]
