Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden staircase for indoor use, which is made into subunits in a prefab house by a wooden panel construction method, and a construction method thereof.

[0002]

2. Description of the Related Art As a wooden staircase in a prefabricated house using a wooden panel construction method, a technique for combining a staircase wall panel with a stepped plate and a staircase unit has been disclosed in Japanese Utility Model Publication Sho 56-174.
It is known from Japanese Patent No. 630.

A wooden stair unit is constructed by fixing a riser plate to the front end side of one step plate, and assembling side plates at the left and right ends of the step plate to form a step of another wooden step unit adjacent to the riser plate. A technique for actually assembling a plate and a plate is known from Japanese Utility Model Publication No. 4-24026.

[0004]

Although the wooden stairs are sub-unitized as described above, first, in the technique disclosed in Japanese Utility Model Laid-Open No. 56-174630, in addition to the stair units, steps are provided. It was necessary to specially prepare the staircase wall panel with the board receiving bar, that is, the wall panel of the staircase had to be specially processed.

Further, in the technique disclosed in Japanese Utility Model Publication No. 4-24026, at least units corresponding to the number of steps of stairs are prepared and connected to the wall panel each time in addition to the connection by actual fixing. Work is required, that is, there is room for improvement in terms of assembly work.

In particular, in the case of a wooden staircase for indoor use, it is desirable to consider the workability while reducing the number of parts and to appropriately form a sub-unit.

[0007] Therefore, an object of the present invention is to provide a minimum necessary sub-unit that can be installed without special processing or complicated assembling work for each step of a wall panel of a staircase, and to improve workability. The objective is to provide a wooden staircase for indoor use that achieves improvement as well as stable quality and shortened construction period.
