Description

  The present invention relates to a rising wall installed at a step portion between an entrance soil and a floor or a step portion between a staircase and a landing, and a floor parting material installed at a step portion between the floor and the floor.

Conventionally, a rising ridge is provided at a step portion between the floor and the floor of the entrance or a step portion between the stairs and the landing. That is, since the rising ridge is provided in a conspicuous place, it is necessary to make fine adjustments so that there are no gaps or steps between adjacent floor boards. In general, a wooden material such as solid wood, plywood, or laminated wood, which is made by bonding a decorative material and integrating it, and chamfering or painting is used. For example, the entrance fence installed in the entrance is provided with a notch portion in advance according to the thickness of the floor board base material, and the floor board base material is inserted into the notch portion of the fence along the base and bonded and fixed. And a floor board is installed so that a clearance gap and a level | step difference may not arise between a fence and a floor board. In that case, fine adjustments such as scraping the upper surface and cut surface of the floorboard are required, which requires skill and time. In addition, firewood is constructed at the initial stage of indoor construction, and may be damaged when carrying building materials, and must be cured with a sheet or the like.

Therefore, a base material with a fitting convex part formed on the top surface and a decorative material to be crowned on the base material is used to attach a decorative material at the final stage of the construction where curing is not required. Is notched according to the thickness of the flooring, and after the flooring is abutted against the mating convex part of the base material, the top surface of the decorative material is covered, resulting in gaps due to irregularities in the cut surface of the flooring. However, a kite configured to be hidden by the top surface portion is disclosed (see Patent Document 1). In addition, by making the top surface of the ridges into an actual structure using the same material and the same pattern as the floor finishing material, the heel and the floor finishing material can be joined together, and there are steps and gaps. A floor finishing structure that does not occur is disclosed (see Patent Document 2).

However, even if curing is done on the slab or floorboard, it takes time to install the curing material, and dust or water may enter through the gap between the curing materials, causing damage to the cocoon, discoloration, mold, etc. There is.
Therefore, it is configured to be detachable with a thin base material and a thin base material molded with plastic or the like so as to have an L-shaped cross section, and covers the corner formed by the horizontal base material and the vertical base material. In addition, a scissor is disclosed that covers the top surface of the front edge of a floor board stretched on a horizontal base material with a thin plate-like decorative material (see Patent Document 3).
According to this method, it is possible to prevent a step from being generated between the floor board and the ridge, and curing is unnecessary because it is only necessary to attach the thin plate-like decorative material to the thin plate-like base material at the final stage of the building work. .

However, there is a possibility that the thin plate-shaped decorative material may bend or break, and it is necessary to work to flatten the surfaces of the horizontal base material and the vertical base material on which the thin plate base material is installed.
In addition, at the step between the high floor surface and the low floor surface, a floor parting material is installed to prevent pedestrians from tripping and injured, but a base material is fixedly installed on the low floor surface, and the base material is There has been disclosed a floor parting material having a structure in which both ends of a covering lid member are brought into contact with a high floor surface or a low floor surface and an engagement piece provided in the middle is engaged with a base material to be fixed (see Patent Document 4).
