  The present invention relates to a lower frame member and a lower structure of an opening.

  The door provided between the bathroom and the dressing room is fitted with an opening frame on the inner surface side of a pillar or plate that is assembled in a rectangular shape on the base placed on the fabric foundation, Mounted on the attached sash frame. The opening frame is composed of an upper and lower frame material and a vertical frame material, and the lower frame material connects the sash frame material and the floor material (flooring material) of the dressing room.

  Conventionally, in this type of lower frame material, a flange extending so as to protrude from the upper surface of the edge is overlapped with the edge of the flooring material so as not to cause a step or a gap with the flooring material. Some have a structure to be provided, and some have an anti-slip rib on the upper surface (see, for example, Patent Document 1).

Such a conventional lower structure of the opening will be described with reference to the drawings.
FIG. 4 is a cross-sectional view schematically showing a lower structure of a conventional opening.
The lower frame member 81 is installed on the upper surface of the base material (discarded plywood) 91 between the dressing room 97 and the bathroom 98. The lower frame member 81 includes a lower plate member 82 made of veneer plywood and an upper plate member 83 in which an ASA resin coat is applied to the surface of an E-ABS resin molded body. The upper plate member 83 is attached on the lower plate member 82. ing.
The lower frame member 81, the vertical frame 84, and the upper frame member (not shown) constitute an opening frame, and the opening frame has a shape that surrounds the opening 99 that partitions the undressing room 97 and the bathroom 98. .

  An aluminum sash frame lower frame 94 is provided on the bathroom 98 side of the lower frame member 81. An end portion 94a of the lower frame 94 on the dressing room 97 side is bent downward and rides on the upper surface of the lower frame member 81 to compress and deform the upper surface of the lower frame member 81 downward. As a result, the end 94a of the lower frame 94 of the sash frame is locked to the lower frame member 81, and the lower frame 94 of the sash frame is fixed.

  Note that a base 90 and a joist 95 are assembled below the base material 91, and the base material 91 is installed thereon.

Therefore, when water, hot water, or the like is applied to the upper surface of the lower frame member 81, there is a problem that there is no escape place of water. For example, between the anti-slip ribs 83b, the lower frame member 81 has a problem over a long period of time. Water sometimes accumulated on the upper surface.

  It is not desirable that water accumulates on the upper surface of the lower frame member 81 for a long time from the viewpoints of safety (for example, prevention of slipping) and hygiene (for example, prevention of mold). In addition, when water has accumulated on the upper surface of the lower frame member 81 for a long time, the occupant has already dried the floor because, for example, a long time has passed since using the bathroom. There is also a problem from the viewpoint of convenience because there is a possibility that the sock may get wet by inadvertently stepping on the lower plate frame 81 while wearing the socks.

  In addition, since there is no escape space for water on the upper surface of the lower frame member 81, there is a possibility that water overflows from the upper surface of the lower frame member 81 when water is applied to the upper surface of the lower frame member 81. In addition, dew condensation water is generated due to a temperature difference between the bathroom 98 (or under the floor) and the dressing room 97, and the water such as water or dew condensation water is absorbed by the upper surface of the floor material 92 in the dressing room 97 and the bottom frame material 81. There is a risk that the water enters between the lower surface of the portion 83c and the moisture oozes out to the base 90, the joist 95, the base material 91, and the like below the lower frame material 81 and corrodes them.

  An object of the present invention is to provide a lower frame material of an opening to which a sash frame for preventing corrosion of a base and a base material under the lower frame material is attached, and a lower structure of the opening. And
