Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, for example, when constructing and constructing wooden stairs in a general house, the rise height of the stairs, the step board position corresponding to the tread width, the riser board position, etc. are set on the side girder surface. TECHNICAL FIELD The present invention relates to a stepping ruler for black stairs that can be displayed and filled in easily and in a short time so that work can be performed quickly, and a stairs manufacturing method using the ruler.

[0002]

2. Description of the Related Art When constructing and constructing wooden stairs in a general house, a predetermined work corresponding to each of a straight staircase having a straight staircase structure and a rotating staircase having a surrounding portion is performed. When constructing a straight staircase, there is a method of marking a dimension line or the like on the side girder surface based on the original size drawing created as the first method. Also,
The second method is to measure the horizontal angle of the step board by straddling a splitting material between the frame on the upper floor and the floor on the lower floor, while the horizontal angle of the side girder is almost equal to this on one side edge. A reference line, which is parallel to, for example, about 6 cm apart, is blackened, and based on this reference line, the raising height corresponding to the horizontal angle of the step plate,
There is a method of setting a tread width and sequentially marking the upper surface position of each step plate and the side surface position orthogonal to this from either one of the upper and lower parts. However, in the second method, even if it is usually performed using a measuring tape, it is very troublesome. Therefore, by making a shape plate with a thin plate material and applying this shape plate to the side girder surface, the ink is sequentially added. Make a mark. In addition, as a third method, the height from the floor on the lower floor to the frame on the upper floor is measured and the kicking height obtained by dividing this by the number of steps, and the horizontal distance from the frame to the side of the first step of the stairs There is a method of sequentially marking with the tread width obtained by dividing by by the number of steps based on the reference line that has been blacked as in the second method.

When constructing a staircase, the first method is to use a side plate without using a side girder, place a swivel plate on a joist that is installed between columns, and nail it. Stop it. That is, while attaching the swivel plate to each of the step plate mounting recesses formed by notching on the joist, while attaching the straight advancing part and incorporating the riser plate, the side girder appears on the side part of the swivel part, A side girder for makeup, which is formed by cutting the stepped plate portion into a cut shape, is inserted. Second
In the case of attaching the side girders in the swivel portion as the above method, the side girders of the straight staircase are blackened as described above, and subsequently, the side girders in the swivel portion are blackened. Third
This is done based on the original size drawing created as a method of the above, and after constructing the straight part, the original size drawing of the surrounding part is created, and according to this original size drawing, the first step tread width, kick up height, second step Draw the drawing by measuring the tread width, kick-up height, and then the upper one in order, and after making this drawing, make a shape plate and transfer the shape plate to the side girder surface. It is a process of blackening.

[0004]

However, according to such a conventional method, not only is it difficult to secure a place for producing a full-scale drawing by the first method when creating a straight staircase, but also it is very troublesome. It hangs. Second and third
In the method of (3), the house is built up, and the actual measurement cannot be done unless the floor is stretched and the frame is attached. Therefore, the process management of the work procedure is unreasonable. It is easy for mistakes to occur.

Further, according to the first method for forming the staircase, it is easy to place and fix the step plate on the joist, but the notch-like cutting of the step plate part in the side girder for makeup is carried out. Not only is it troublesome to stamp the ink for forming it, but the appearance is not good because a gap is created when the ink is inserted later. With the second method, the kick height and tread width are difficult to set, and it is troublesome because it may be repeated over and over, and even with this method even for unskilled workers. There were things I couldn't do. The third method is extremely troublesome because it takes time and effort to create a full-scale drawing and transfer it.

Therefore, the present invention has been made in view of the above-mentioned various existing circumstances.
It is possible to perform the blacking work accurately and quickly showing the mounting position of each riser plate, and to easily and clearly indicate not only the straight stairs but also the flat L-shaped or U-shaped rotating stairs.
