Description

  The present invention relates to a drain drainage groove material that can be directly attached between flooring materials or between flooring material and a side wall with substantially the same thickness as the flooring material without gaps on the floor surface of a corridor or landing, and in particular, it relates to the amount of drain water. In particular, the present invention relates to a drain drainage groove material that smoothly drains drain water from a drain drainage channel and does not contaminate the periphery thereof with drain water.

  There are various types of drain drainage grooves that can be directly attached to the floor of the corridor, and these are condominiums, corridors, verandas, stairs and landings, and equipment such as indoor heat pump air conditioners. It is used in many ways as a material that quickly drains the drain water discharged from the outside and fulfills its purpose of use.

  In recent years, most of the various concrete apartments such as condominiums have been increasingly required to install heat pump type air conditioners in the living rooms facing the outdoor corridors, and the drain water has become less aesthetic, and drainage measures are now indispensable. It has become. For drainage countermeasures, there is a means such as digging a groove in the floor concrete of the outdoor corridor and burying a pipe in this groove, but it also causes cracks in the concrete frame, and its construction is complicated and construction costs and management There was a problem that the cost was expensive.

Therefore, for example, as disclosed in Patent Document 1, while a floor sheet is laid in the outdoor corridor, the floor sheet has substantially the same thickness as the outdoor corridor floor sheet, and is adhered to the floor of the outdoor corridor together with the floor sheet. A drain drainage groove having a shallow drainage drainage channel formed in the longitudinal direction at a substantially center in the width direction on the surface of the belt-like sticking plate to be in contact with or joined to the edge of the floor sheet. Materials have been proposed.
This drain drainage groove material can be provided with a drain drainage channel simply by sticking the drainage drainage groove material to the floor concrete, so there is no defect in the concrete frame, and the construction is simple and the construction management is easy. Therefore, it has the merit of reducing construction costs and construction management costs.
However, the conventional drain drainage groove material is made of a synthetic resin such as vinyl or olefin, and exhibits water repellency even in the drainage channel, so that the drain water rises due to surface tension and becomes water droplets. When the amount of drain water is small, it is difficult for the drain water to flow out of the drain drainage channel. On the other hand, when the amount of drain water is large, there is a problem that the drain water overflows from the drain drainage channel.
In addition, since the drain water stays without flowing out from the drain drainage channel for a long period of time, there is a problem such as generation of scale.

  Hereinafter, embodiments of the drain drainage groove material of the present invention will be described based on the drawings.

  1 to 2 show an embodiment of the drain drainage groove material of the present invention.

This drain drainage groove material 1 is a belt-like material that is attached to the floor 2 by abutting or joining edges of the floor sheet 3 made of synthetic resin, linoleum, rubber or the like that is attached to the floor 2 of the corridor or veranda. The body 4 and a cover 5 that is detachably disposed on the band 4 and has a height substantially equal to the maximum thickness of the band 4 when mounted, and a longitudinal direction substantially in the center of the surface of the band 4 in the width direction. In addition, a drain drainage channel 41 that also serves as a mounting portion for the cover 5 is formed, and a plurality of linear small grooves 42 having a width of 0.5 to 2 mm (1 mm in this embodiment) are formed on the bottom surface of the drain drainage channel 41. , 0.5 to 5 mm (4 mm in the present embodiment), and is formed in the longitudinal direction.
As a result, the water droplets of the drain water flowing into the drain drainage channel 41 are quickly discharged while being connected by the small groove 42 (by a kind of capillary phenomenon of the small groove 42 having a width of 0.5 to 2 mm). Regardless of the amount, the drain water can be smoothly discharged from the drain drainage channel 41.

In this case, it is preferable that the maximum thickness of the strip 4 does not exceed three times the thickness of the floor sheet, and the absolute value of the maximum thickness of the strip 4 is 10 mm or less, preferably , 8 mm or less, more preferably 6 mm or less (5.5 mm in this embodiment).
Thereby, the connection part of the location which provided the drain drainage groove | channel material 1 and the floor sheet 3 can be formed gently, and accidents, such as a person kicking at the time of use, can be prevented.

The cover 5 is formed with a flat upper surface (or a gentle arch) so that it has the same height as the maximum thickness of the strip 4 when attached, and when the cover 5 is attached to the strip 4, A leg portion 51 to be grounded is formed on the bottom surface of the path 41.
In addition, a plurality of linear protrusions 52 having a width of 0.5 to 5 mm (in this embodiment, 2 mm) are provided on the upper surface of the cover 5 to prevent slipping, if necessary. In this embodiment, it can be formed in the longitudinal direction at an interval of 7.5 mm).

The belt-like body 4 and the cover lid 5 are opposite to each other (the inner side surface of the drain drainage channel 41 of the belt-like body 4 and the outer side surface of the leg portion 51 of the cover lid 5). Is a fitting between corrugated ribs, and such a fitting and locking state is realized by elastic deformation of the synthetic resin.
Thereby, the integrity of the cover 5 with respect to the strip | belt-shaped body 4 can be improved, and accidents, such as the cover 5 being removed at the time of use, can be prevented.
In order to further improve the integrity of the cover 5 with respect to the belt-like body 4, as shown in FIGS. 3 (a) and 3 (b), the retaining portions 44a, 54a, 44b having a retaining shape are provided. , 54b can be formed.

The leg portion 51 of the cover 5 is formed on the bottom surface of the drain drainage channel 41 when the leg portion 51 is attached to the belt-like body 4, so that even if a pedestrian steps on the cover 5, the cover 5 is drained. Although it does not sink into the drainage channel 41, for example, when the strength of the cover 5 is insufficient because the width of the cover 5 is large, as in the second modified embodiment shown in FIG. When the cover 5 is attached to the belt-like body 4, a plurality of linear support ribs 55 having a width of 1.0 to 5 mm (2 mm in this embodiment) that are grounded to the bottom surface of the drain drainage channel 41 are provided. It can be formed in the longitudinal direction at intervals of -10 mm (7.5 mm in this embodiment).
In consideration of water permeability, the support rib 55 is usually not grounded to the bottom surface of the drain drainage channel 41 and is slightly (for example, 0.5 to 2 mm) between the bottom surface of the drain drainage channel 41. It is also possible to form a water space so that when the pedestrian steps on the cover 5, the cover 5 sinks and contacts the bottom surface of the drain drainage channel 41.

By the way, in this embodiment, the bottom surface of the drain drainage channel 41 is formed flat except for the small groove 42. However, as in the third modified embodiment shown in FIGS. It can be formed in a shape curved downward with a predetermined curvature.
Here, the drain drainage channel 41 may be configured by one curved surface as shown in FIG. 5 (a), or as shown in FIG. Or more).
Thereby, since the water droplets of the drain water that has flowed into the drain drainage channel 41 are collected at the lower part of the drain drainage channel 41, the drainage water is easily drained, and the drain water can be more smoothly discharged from the drain drainage channel 41.

  Further, the bottom shape of the drain drainage channel 41 including the small groove 42 is quick while the water droplets of the drain water flowing into the drain drainage channel 41 are connected by the small groove 42 (by a kind of capillary phenomenon of the small groove 42 having a width of 0.5 to 2 mm). As long as it can be discharged, the present invention is not limited to that of the above-described embodiment, and a small groove 42 is formed in a V shape in a cross section as in the fourth modified embodiment shown in FIG. As in the fifth modified example shown in FIG. 6B, the small groove 42 can be defined and formed by a ridge having a curved top surface.

The material of the strip 4 and the cover 5 constituting the drain drainage groove material 1 is not particularly limited, such as metal, synthetic resin, etc., but is preferably soft, semi-soft, hard synthetic resin, more preferably chloride Thermoplastic resins such as vinyl resins such as vinyl and vinyl acetate, olefin resins such as polyethylene and polypropylene, and copolymer resins such as ethylene-vinyl acetate can be employed.
In particular, by forming with a thermoplastic resin, it is easy to join the floor sheet 3 and the strip 4 and the construction can be performed easily.

Further, the drain drainage groove material 1 is hydrophilic and / or antifouling at least on the inner surface of the small groove 42 of the drain drainage channel 41 by forming a coating film containing a hydrophilic and / or antifouling functional agent. A functional agent can be applied, or the belt-like body 4 can be formed into a layer structure, and the surface layer can be formed of a synthetic resin containing a hydrophilic and / or antifouling functional agent.
Here, in order to make the belt-like body 4 into a layer structure, for example, a hydrophilic functional agent (surfactant) is added to a synthetic resin layer having a thickness of about 0.2 mm that constitutes the surface layer of the drain drainage channel 41 of the belt-like body 4. ) Can be molded by two-layer extrusion using a synthetic resin in which 2 parts by weight or more is mixed with 100 parts by weight of the synthetic resin. In addition, the thickness of a surface layer is not limited to this, It can be made thicker than 0.2 mm according to the usage condition of the drain drainage groove | channel 1, etc., or can be made thin.
In addition, the coating film and the surface layer containing the hydrophilic and / or antifouling functional agent are the entire drain drainage channel 41 other than the inner surface of the small groove 42 of the drain drainage channel 41, the entire inner surface part of the cover lid 5, It can also be provided on the entire surface of the drainage ditch material 1.
In addition, in the case where the coating film or surface layer containing the hydrophilic and / or antifouling functional agent is the same type of synthetic resin as the base material of the drainage drainage groove material 1 or a different type of synthetic resin, the drainage drainage groove A synthetic resin constituting the base material of the material 1 and a synthetic resin that is familiar to each other are used.
In addition, when a vinyl chloride resin is used as the synthetic resin, a hydrophilic functional agent (surfactant) is mixed in, which causes stickiness in combination with the action of the plasticizer contained in the synthetic resin. However, this problem is caused by mixing a hydrophilic functional agent (surfactant) only in the synthetic resin constituting the surface layer of the drainage channel 41 of the belt-like body 4. The point can be solved.
Thereby, drain water can be made to flow out more smoothly from the drain drainage channel 41 at low cost, and it is possible to prevent dirt and scale from adhering to the drain drainage channel 41, particularly the small groove 42. .

As the hydrophilic functional agent (surfactant), specifically, a polyhydric alcohol partial ester derived from a polyhydric alcohol and higher fatty acids can be suitably used.
Here, as the polyhydric alcohol, sorbitan, pentaerythritol, trimethylolpropane, glycerin and the like can be used alone or in combination of two or more.

As shown in FIG. 2, the drain drainage groove 1 abuts the edges of the belt-like body 4 made of synthetic resin, linoleum, rubber or the like, which is adhered to the floor 2 of the corridor or veranda. Or it joins and affixes to the floor 2, and attaches the cover 5 and is used.
Drain water generated in the air conditioning indoor unit falls to the drain storage block 7 through the drain pipe 6 and the strip 4 of the drain drainage groove member 1 connected to the drain storage block 7 without overflowing the drain water. Flows into the drain drainage channel 41 of Here, the drain storage block 7 is a means for preventing the backflow of drain water into the room, and many techniques relating to this are publicly known and are not particularly limited.
Then, since the water droplets of the drain water flowing into the drain drainage channel 41 are quickly discharged while being connected by the small groove 42 (by a kind of capillary phenomenon of the small groove 42 having a width of 0.5 to 2 mm), the amount of the drain water is reduced. Regardless of the amount, the drain water smoothly flows out from the drain drain channel 41 to the drain side groove 21 formed in the corridor or the veranda.
Thus, this drain drainage groove material 1 can smoothly drain drain water from the drain drainage channel 41 regardless of the amount of drain water, and even when there is a large amount of drain water, it overflows to the outside. In addition to being able to prevent, the cover 4 is used by attaching the cover 5 to the belt-like body 4, so that it is possible to eliminate the scattering of drain water by walking and to prevent the floor surface from being soiled and slipped.

  As described above, the drain drainage groove material of the present invention has been described based on the examples thereof, but the present invention is not limited to the structures described in the above examples, and the structure is appropriately set within the scope not departing from the gist thereof. Can be changed. For example, instead of mixing a hydrophilic functional agent (surfactant) into the synthetic resin constituting the surface layer, the synthetic resin constituting the surface layer is made hydrophilic with a hydroxyl group such as ethylene vinyl alcohol or polyvinyl alcohol. An excellent synthetic resin can be used. In this case, since ethylene vinyl alcohol is a thermoplastic resin, in particular, the thermoplastic resin should be selected as the base material constituting the drainage groove material. Thus, two-layer extrusion molding becomes possible, and by this, the drain drainage groove material including the surface layer is formed by integral molding, whereby the drainage drainage groove material can be manufactured in one step. In addition, the types and mixing ratios of synthetic resin paints (hydrophilic functional agents (surfactants)) in which hydrophilic functional agents (surfactants) are mixed into the base material constituting the drain drainage groove are as described above. The surface layer is formed by applying a hydrophilic synthetic resin-based paint, and after application, it is firmly applied by heat, electromagnetic waves such as ultraviolet rays, radiation such as electron beams, etc. It can also be fixed. In this case, when an olefin-based resin is used as the synthetic resin constituting the base material of the drain drainage groove material 1, a surface layer is formed through the primer layer. It is necessary to consider the adhesion between the material and the surface layer.

  The drain drainage groove material of the present invention can smoothly drain drain water from the drain drainage channel regardless of the amount of drain water, and is therefore suitable for drainage drainage groove materials applied to corridors and veranda floors. Can be used.
