Description

  The present invention can improve the drainage structure of the bathroom floor, more specifically, in a bathroom floor constructed by laying a floor sheet made of a soft resin, can prevent peeling, dirt and damage at the end of the floor sheet. The present invention relates to a bathroom floor drainage structure in which water smoothly flows from a floor sheet to a drainage section, and a bathroom floor parting material used for the drainage structure.

  As is well-known, in conventional bathrooms, tiled floors with excellent durability, which are difficult to get dirty and do not easily crack, etc. were generally adopted, but when tiled floors are walked barefoot The body temperature was taken away by the tiles, causing unpleasant coldness, and when falling in the bathroom, the head and body were hit against a hard floor and injured.

  Therefore, in recent years, in order to avoid the problems of comfort and safety in use, which have been in the tiled floor, there are an increasing number of cases adopting a floor structure in which a floor sheet made of a soft resin is laid. Incidentally, the applicant has previously developed a soft resin floor sheet with improved drainage function and has filed a patent application (Japanese Patent Application No. 2013-139410).

  However, for the floor sheet, although the floor sheet was laid to the boundary of the drainage hole and drainage groove at the time of construction, the end of the floor sheet was exposed (see Patent Documents 1 and 2). Problems such as the edge of the floor sheet peeling off from the floor base, soiling due to drainage, and being scratched when polished with a brush or the like were liable to occur.

  Moreover, even when using a parting frame that protects the end of the floor sheet, if the parting frame is simply arranged along the end of the floor sheet, the flow of water from the floor sheet to the drain outlet is caused by the parting frame. Since it is obstructed and adversely affects the water drainage of the bathroom floor, it was necessary to devise the parting frame shape so as not to cause a problem in the drainage function.

Spacer protrusions can be provided at predetermined intervals on the ridges 51 so that the gaps between the ridges 51 of the parting material 5 can be easily secured.

Example 4
Next, a fourth embodiment of the present invention will be described below based on FIGS. 11 (a) and 11 (b). In this Example 4, in the bathroom parting material 5 used for the same application as that of Example 3, a hard polyvinyl chloride resin is used as the material of the upper surface part 51a of the ridge part 51, and the ridge part. The material of the 51 rising portions 51b is made of soft vinyl chloride resin.

  As a result, the abrasion resistance against the casters and the like traveling on the linear parting material 5 can be maintained by the upper surface portion 51a made of the hard resin, and the impact generated when the caster passes over the parting material. Can be relaxed by elastically deforming the rising portions 51b and 51b made of a soft resin.

  Furthermore, in the present embodiment, the convex strip 51 of the linear parting material 5 has a rectangular cylindrical hollow structure, and a hard resin is used as the material of the upper wall portion constituting the upper surface 51a of the convex strip 51. Since the material of the side wall portions constituting the rising portions 51b and 51b of the ridge portion 51 is made of soft resin, the rising portions 51b and 51b are bent to easily absorb the impact.

  Further, when a soft resin is used as the material for the linear parting material 5, problems such as germs and molds are more likely to occur than in the case of using only a hard resin. The hygienic problem is prevented by using a soft resin to which an antibacterial / antifungal agent is added for the rising portion 51b of the ridge 51.

  Furthermore, in this embodiment, since the upper surface portion 51a of the ridge 51 of the linear parting material 5 is an inclined surface that goes downward, the linear parting material 5 is in the same state as in FIG. When installed in the above, the flow of water from the floor sheet 3 to the drainage groove D becomes smoother.

  In this embodiment, hard vinyl chloride resin is used for the upper surface portion 51a of the ridge 51, but other synthetic resin materials can be used as long as they are hard resins. Moreover, as for the material of the rising portion 51b of the ridge 51, the soft vinyl chloride resin is used in this embodiment, but other soft resins and thermoplastic elastomers may be used.

  Moreover, in this embodiment, the hollow part 51 is formed in the linear parting material 5, but if there is no problem in the manufacturing cost and the impact suppressing effect when passing through the caster, there is no hollow part. The solid ridges 51 can also be formed.

  The present invention is generally configured as described above. However, the present invention is not limited to the described embodiments, and various modifications can be made within the description of “Claims”. About the material of the material 1 or the annular parting material 5, if it is a material excellent in waterproofness and durability, metal materials other than a synthetic resin material can also be employ | adopted.

  Further, regarding the floor sheet 3, not only the floor sheet 3 made of a soft resin or a rubber material but also one made of a hard material such as FRP or a tile board can be used. Also, the sealing material 4 can be freely selected from synthetic resins such as silicon and urethane, mortar, etc., and any of them belongs to the technical scope of the present invention.

  In recent years, there has been a demand for plastic or rubber flooring that is difficult to be injured even if a child or an elderly person falls in a public bath or a nursing facility. Under such circumstances, the bathroom floor drainage structure and bathroom floor parting material of the present invention are useful techniques that can protect the edge of the flooring without deteriorating water drainage.
