Further, a quaternary ammonium salt-based surfactant or the like is used as an antistatic agent.

Hereinafter, the present invention will be described in detail with reference to exemplary drawings. FIG. 1 is a longitudinal sectional view of an example of a member for drainage according to the present invention, FIG. 2 is a plan view of an example of the member, and FIG.
4 shows a partially enlarged view of a plan view of an example of the same member, and FIG. 4 shows a rear view of an example of the same member. As shown in FIGS. 1 to 3, the member 1 has a passage portion for drainage, that is, a water passage portion 2, and a frame portion 3 provided for forming the water passage portion. The width W of the member 1 needs to be included in any range of 28 to 32 mm, 33 to 37 mm, or 38 to 42 mm. The width of 28 to 32 mm is equivalent to the width obtained by cutting the floor material to the width of the JIS ruler of 60 cm, and 33 to 37 m
The width of m is equivalent to the width of the floor material cut out to the width of the JIS ruler of 1.0 m, and the width of 38 to 42 mm is 1.5 m
This is because the width of the floor material is notched to the width of the JIS ruler. By setting the width of the drain groove member to such a width, the floor material can be cut out along the width of the JIS ruler as it is, so that the portion where the member is fitted can be formed in the floor material. As described above, there is no need to use a so-called layout method of performing construction while performing measurement work with a ruler or the like, and construction efficiency is improved.

The height H of the frame 3 is preferably substantially the same as the thickness of the floor material to be constructed together from the viewpoint of construction work, safety, etc. Specifically, the height H is 2 to 10 mm is preferred. Further, the height h inside the frame portion needs to be at least 0.5 mm or more. 0.5
If it is less than mm, it is difficult to drain the water stably, for example, the drainage flows out of the drainage member.

The widths w and w 'of the frame 3 are 3
mm or more is preferable. If the width is smaller than this, the stability of the shape and the workability cannot be secured. On the other hand, the upper limits of the widths w and w 'of the frame portion 3 may be arbitrarily determined as long as the width W' of the water-passing portion can be 19 mm or more. The reason why the width W 'of the water passage section is required to be 19 mm or more is to prevent the drainage from overflowing from the drainage member and to ensure a smooth drainage. Therefore, the widths w and w 'of the frame portion 3 need not always be equal. For example, in a drainage groove member having a width of 35 mm, the width w of one frame portion may be 3 mm, and the width w 'of the other frame portion may be 7 mm. The width of the frame portion does not need to be uniform in the width direction as long as the width of the water-passing portion is 19 mm or more. For example, the frame portion 3 may have a shape such as a wavy shape or a meandering shape.

In FIG. 1, the thickness ht between the lower surface of the water passage portion and the groove portion on the rear surface must be 0.5 mm or more.
If the thickness is less than 0.5 mm, a problem such as breakage occurs, and handling becomes difficult. Regarding the groove 4 provided on the back surface of the water passage section 2, the depth of the groove is 0.1 mm or more, 0.5 mm or less, and the width is 0.5 to 1 from the viewpoint of securing the adhesive strength.
It is preferably 0 mm or less. If the depth of the groove 4 is less than 0.1 mm, a sufficient improvement in the adhesive strength is not recognized.
This is because the adhesive strength is not sufficiently distributed, and the bonding strength is rather lowered. Also, when the width wm of the groove is 0.5 mm or less or 10 mm or more, the adhesive does not spread over the entire groove, and the adhesive strength is reduced. When the depth hm of the groove portion is 0.1 mm or more and 0.5 mm or less, the adhesive enters the groove portion, so that the bonding area increases, and as a result, the bonding strength is improved. The groove may have a U-shape, a wavy shape, a semi-circular shape, or any other shape as long as the adhesive can enter the groove during bonding. FIG.
(E) shows a partial cross-sectional view of an example of the shape.

The surface condition of the water passage portion may be flat or a convex portion may be provided. FIG. 6 shows an example of a vertical cross-sectional view in the case where a convex portion is provided in the water passage portion, and FIG. 7 shows an example of a partially enlarged view of a plan view in which the convex portion is provided in the water passage portion. By providing the convex portions 7, water flows along the grooves 8 between the convex portions, so that drainage becomes smoother. The number of the convex portions 7 provided to exhibit such an effect is arbitrary two or more. It is preferable that the width wh of the groove formed by the convex portion 7 is 0.5 mm or more. Further, the groove 8 formed by the convex portion 7 does not need to be uniform as long as the width is within such a range. In addition, it is preferable that the height h ″ of the convex portion 7 is not higher than the height h ′ inside the frame portion from the viewpoint of safety such as prevention of stumbling.
In addition, similar to the case where the water passage portion does not have a convex portion,
The thickness ht ′ between the lowermost portion of the groove 8 and the back surface groove 4 ′ needs to be 0.5 mm or more from the viewpoint of preventing damage. Furthermore, the shape of the vertical cross-sectional view of the convex portion provided in the water passage portion is a waveform, a semicircle,
Any shape such as a U-shape is acceptable. FIG. 8 shows an example of the shape of the convex portion.
(A) to (e).

In addition to the purpose of facilitating drainage, FIG.
As shown in (2), two convex portions 9 may be provided in the water passage portion to form a groove (hereinafter, referred to as a drain hose mounting portion 10) for mounting a drain hose of the air conditioner. In this case, in order to achieve consistency with the outer diameter of the drain hose, a groove formed between the convex portions, that is,
It is necessary that the radius of curvature of the drain hose mounting part 10 is 7 to 20 mm. In addition, it is preferable that the drain hose installation part 10 is provided with the convex part 9 so that the drain hose is installed in the middle of the water passage part. In addition, a finer convex portion including the drain hose installation portion 10 and a portion other than the installation portion may be provided. (See FIGS. 10 to 12) By providing the drain hose mounting portions 10 ', 10'', and 10''', drainage from a drain hose of an air conditioner or the like can be made smoother.

The granular material is a material having a higher melting point than the synthetic resin constituting the drainage member of the present invention, and refers to a crushed material having a certain size. The granular material itself is organic,
Any of inorganic substances may be used. Specifically, in addition to the above-described materials such as calcium carbonate, talc, silicon dioxide, clay, magnesium carbonate, aluminum hydroxide, and aluminum sulfate as the filler, mica can be exemplified.
Metals such as aluminum and copper may be used. Also,
When the synthetic resin constituting the drainage member of the present invention is a polyvinyl chloride resin and / or a vinyl chloride-vinyl acetate copolymer, in addition to the above, PET and P
BT, polypropylene, polycarbonate and the like can be suitably used. On the other hand, the fibrous material is a material having a higher melting point than the synthetic resin constituting the drainage member of the present invention,
It refers to a fibrous material of a certain size and thickness. The material of the fibrous material may be either organic or inorganic. However, in the case of inorganic substances, metal fibers are used. In addition, the synthetic resin constituting the drainage member of the present invention is a polyvinyl chloride resin, and / or
Alternatively, in the case of a vinyl chloride-vinyl acetate copolymer, polyester can be suitably used as a synthetic resin in addition to the above.

At the time of construction, both sides of the mortar or the like are fitted with the drainage groove member of the present invention at about 50-
After laying the floor material with an adhesive, leaving 500 mm, place a JIS ruler on the portion where the drainage member is fitted,
