2. Description of the Related Art In recent years, most of concrete condominiums such as condominiums are required to be equipped with a heat pump type air conditioner in the living room facing the outdoor corridor. Has become. As for this drainage drainage measure, there is a method such as digging a groove in the floor concrete of the outdoor corridor and burying a pipe in this groove, but cracks occur in the concrete skeleton, construction is complicated and construction costs and construction management costs There was a problem that was expensive.

Therefore, as disclosed in Japanese Patent No. 2966352, while a floor sheet is laid in an outdoor corridor,
Drain drainage with a shallow groove in the longitudinal direction at approximately the center in the width direction is formed on the surface of the strip-shaped adhesive plate that has a thickness substantially equal to that of the floor sheet for the outdoor corridor and is adhered to the floor of the outdoor corridor together with the floor sheet. There has been proposed a drain drainage channel member having a channel formed so that the edge portion abuts or joins with the edge portion of the floor sheet. With this drainage drainage material, the drainage drainage channel can be provided by simply attaching the drainage drainage material to the floor concrete.Therefore, the concrete frame will not be damaged, and the construction will be easy and construction management will be easy. Therefore, it has an advantage that the construction cost and the construction management cost can be reduced.

[0004]

By the way, since the conventional drainage drainage material is made of a synthetic resin such as vinyl chloride and exhibits water repellency in the drainage drainage channel as well, the drainage water has a surface tension. There is a problem that the drain water does not easily flow out from the drainage channel when the drainage water is in the form of water droplets when it rises, and when the drainage water is large, the drain water overflows from the drainage channel. there were.

In view of the problems of the conventional drainage drainage material, the present invention forms a small flow rate drainage channel in the drainage drainage channel to drain the drainage water regardless of the amount of drainage water. It is an object of the present invention to provide a drain drain groove material that can be smoothly discharged from a passage.

[0006]

In order to achieve the above object, the drainage ditch material of the present invention has a thickness substantially equal to that of a floor sheet for a corridor, and is attached to the floor of the corridor together with the floor sheet. On the surface of the band-shaped adhesive plate, a drain drain made of a shallow groove is formed in the longitudinal direction at approximately the center in the width direction, and the drain is made of synthetic resin so that the edge contacts or joins with the edge of the floor sheet. In the drainage ditch material, at least one drainage channel for small flow rate having a curved surface shape having substantially the same curvature in the longitudinal direction is formed in the drain drainage channel.

This drain drainage material is used for drain drainage channels.
Since at least one drainage channel for small flow rate having a curved shape with substantially the same curvature in the longitudinal direction was formed, even if the drain water is small, by flowing this drainage channel for small flow rate, the water depth is increased and the water pressure This allows smooth drainage from the drainage channel. In addition, if there is a sudden change in the cross section of the small flow drainage channel, dust is likely to accumulate at that location, and mold or the like is likely to occur. Since it is formed in the groove shape, it is possible to prevent generation of mold and the like without collecting dust.

In this case, the upper portion of the drain drainage channel can be covered with a lid.

Thus, even when the drain water is large, it is possible to prevent the overflow of water to the outside, to prevent the drain water from scattering due to walking, and to prevent the floor surface from being soiled or slipped.

In addition, the drain drain groove material has a layered structure, and a surfactant (including a hydrophilic substance in the present specification) is mixed in the synthetic resin forming the surface layer of the drain drainage channel,
A hydrophilic resin can be used.

As a result, the drain drainage channel can be rendered hydrophilic to prevent independent formation of drain water droplets, and drain water can be more smoothly discharged from the drain drainage channel regardless of the amount.

Further, the drain drain groove member including the surface layer can be formed by integral molding.

Thus, the drain drain groove material can be manufactured in one step.

It can also be formed by applying a surface layer to a substrate.

Thus, the surface layer can be easily formed on the drain drain groove material.

Since the drainage channel 91 for the small flow rate having a curved surface shape with substantially the same curvature in the longitudinal direction is formed in the drainage channel 9, even if the drain water is small, the drainage channel 91 for the small flow rate allows the water depth to be increased. Drain drainage channel 9 due to increased water pressure
Can be drained smoothly. Further, if the small flow drainage channel 91 undergoes a rapid cross-section change, dust is likely to accumulate at that location, and mold or the like is likely to occur. Since the groove is formed in a curved surface, it is possible to prevent the accumulation of dust and the prevention of mold and the like.

When a vinyl chloride resin is used as the synthetic resin forming the drainage drainage material 1, by mixing a surfactant (hydrophilic substance), the action of the plasticizer contained in the resin is counteracted. It also causes stickiness, which reduces the adhesiveness to the floor of the corridor, but a surfactant (hydrophilic substance) is mixed only in the synthetic resin forming the surface layer of the drainage channel 9. By doing so, this problem can be solved.

The drain drainage material of the present invention is as described above.
Although described based on the embodiment, the present invention is not limited to the structure described in the above embodiment, and the structure can be appropriately changed without departing from the spirit of the invention. For example, instead of mixing a surfactant (hydrophilic substance) into the synthetic resin forming the surface layer, the synthetic resin forming the surface layer has a hydroxyl group such as ethylene vinyl alcohol or polyvinyl alcohol, which is excellent in hydrophilicity. Synthetic resin can be used, in this case,
In particular, since ethylene vinyl alcohol is a thermoplastic resin, it is possible to perform two-layer extrusion molding by selecting the thermoplastic resin as the material of the base material that constitutes the drainage drainage material. By forming the drain drainage groove material including the element by integral molding, the drain drainage groove material can be manufactured in one step. Further, the synthetic resin coating material (surfactant (hydrophilic substance) type and mixing ratio) obtained by mixing the surfactant (hydrophilic substance) into the base material forming the drainage ditch material is the same as in the above example. The same) or a hydrophilic synthetic resin coating to form the surface layer, and after application, firmly fix it by heat, electromagnetic waves such as ultraviolet rays, radiation such as electron beams, etc. You can also In this case, drain drainage gutter 1
When an olefinic resin is used as the synthetic resin forming the base material, the adhesive layer between the base material and the surface layer of the drainage gutter 1 is formed by forming the surface layer through the primer layer. Need to consider.

[0027]

According to the drainage drainage material of the present invention, since at least one drainage channel for small flow rate having a curved surface shape having substantially the same curvature in the longitudinal direction is formed in the drainage channel, a small amount of drain water is produced. Even in the case, the depth of water can be increased by flowing through the drainage channel for small flow rate, and the drainage channel can smoothly flow out due to the water pressure. In addition, if there is a sudden change in the cross section of the small flow drainage channel, dust is likely to accumulate at that location, and mold or the like is likely to occur. Since it is formed in the groove shape, it is possible to prevent generation of mold and the like without collecting dust.

Further, by covering the upper part of the drain drainage channel with a lid, it is possible to prevent the overflow of drain water to the outside even when a large amount of drain water is present, and to prevent the drain water from splashing due to walking and to clean the floor surface. And slip can be prevented.

Further, the drain drainage channel has a layered structure, and a surface active layer of the drain drainage channel is mixed with a surfactant (hydrophilic substance) or a hydrophilic resin is used, whereby the drain drainage channel is formed. It is possible to prevent the drain water from becoming water droplets independently by imparting hydrophilicity to the drain water so that the drain water can be more smoothly discharged from the drain drainage channel regardless of the amount.

Further, by forming the drain drain groove material including the surface layer by integral molding, the drain drain groove material can be manufactured in one step.

By forming the surface layer by applying it to the base material, the surface layer can be easily formed on the drain drain groove material.
