JP 2001-159219 A JP 2003-41731 A

  Reforming the top end of the upper surface of the existing protruding nose has so far been covered by a nose decoration or a decorative tread. Therefore, there were the following problems.

  For example, in the staircase structure, the nose portion is a place where the friction of the sole of the foot is the largest when a human moves up and down, and the nose portion is worn away. In the renovation staircase, it is unsightly that the renovated stair nose is worn away and the existing stair nose is exposed. Therefore, in order to prevent the existing nosing part from being exposed even if the nosing decoration material is worn down, it is necessary to increase the thickness of the nosing decoration material covering the upper surface of the tread board or to increase the thickness of the decorative tread board. However, since the nosing decoration and the decorative tread board are joined together, if the thickness of the joint is not the same, a step will be created, the appearance will be bad, and even when the human being goes up and down There is a possibility of injury to the soles of the feet. In addition, the thicker the decorative tread, the higher the cost and the more difficult the construction at the site. Therefore, in the conventional renovation construction, in order to reduce the cost and facilitate the construction, a method of making the decorative tread board as thin as possible is taken. However, in this method, the thickness of the nose decoration material covering the top surface of the tread board is inevitably reduced, so the top end of the upper surface of the reformed protruding nose portion is worn away by the friction of the soles of the feet when a human moves up and down. The existing nose portion is easily exposed.

  Also, the nose portion of the staircase needs to be solid because a load is easily applied when a human moves up and down the staircase. In the conventional renovation staircase, as described above, the renovation of the stair nose is covered with a stair nosing decorative material or a decorative tread board, and the attachment is only durable with screws and adhesive, so it is durable Is in danger.

  Further, when a decorative kick plate is attached to an existing kick plate, the thickness of the conventional decorative kick plate is as thin as about 2 mm, so that it can be easily damaged by the impact of a human being raised or lowered.

  In the renovation construction process, it becomes important how to save the labor of construction. Since the stairs are made according to various standards, when renovating the stairs, construction is usually performed by matching the shape of each member on site. Therefore, each member such as a conventional decorative kick board, a nosing decoration material, and a decorative tread board must be directly attached to an existing staircase, and it takes time and effort to adjust the shape of the member in the field.

  The present invention has been made in view of the above-mentioned reasons, and its object is to improve the durability of the reformed nose portion and at the same time improve the durability of the decorative kick plate, and shape the members in advance.
