2. Description of the Related Art Wooden stairs provide an elegant feeling indoors by processing pillars, handrails, and the like into various shapes because wood, which is a material thereof, is easily processed. In particular, as shown in FIG. 1 as an oblique view of an example of a stairway ascending port viewed from obliquely above, the outer peripheral shape of the pillar lower mounting portion 1a at the end of the starting step 1 constituting the treadboard at the lowermost stage of the stairway is circular. In the case of a structure that is formed in an arc shape and protrudes indoors, a decorative handrail 2 having a spiral shape, an arc shape, a disk shape, or the like is used as a handrail located above the pillar lower mounting portion 1a. A luxurious thing is that a plurality of pillars consisting of one main pillar 3 thicker than the main pillar 3 and one or more child pillars 4 thinner than the main pillar 3 are attached between the mounting part 1a. Become.

[0003] In mounting such a pillar, the pillars 3 and 4 in the pillar lower mounting portion 1a at the end of the starting step 1 and the decorative handrail 2 above, which constitute the tread plate at the bottom of the riser, are mounted. The mounting hole position must correspond exactly to the vertical direction. This means that at least the mutual positional relationship between the mounting holes of the pillar lower mounting portion 1a of the starting step 1 and the decorative handrail 2 on the plane must be completely matched.

However, the work of drilling a pillar mounting hole in the lower pillar mounting portion 1a of the starting step 1 depends on the relationship with other stairs and the surrounding structures and the upper part of the starting step 1. Since the shape of the decorative handrail 2 that can be positioned at
In some cases, only through holes for mounting pillars are drilled in the factory in advance, but at least the pillar mounting holes for the child pillars 4 are not drilled, so they must be drilled at the construction site of the stairs. If a through hole for mounting the main pole 3 is not previously formed in the lower mounting portion 1a of the starting step 1, a column mounting hole for the main pole 3 is also formed at the construction site of the stairs. In addition to the above, if a pillar mounting hole has not been previously drilled in the lower surface of the decorative handrail 2 at the factory, the lower surface of the decorative handrail 2 for the main pillar 3 and the child
You must also drill holes for mounting columns.

As described above, in order to drill a pillar mounting hole at an accurate position in the lower part of the pillar mounting portion 1a of the starting step 1 and, if necessary, also on the lower surface of the decorative handrail 2 at the construction site of the stairs, First, it is necessary to mark the exact position of the pillar mounting hole on the member for drilling the pillar mounting hole. Conventionally, such a mark of the pillar mounting hole position is provided by the pillar lower mounting portion 1a of the starting step 1 and the decorative handrail 2 A predetermined fixed point on the member for forming the pillar mounting hole is marked, a line connecting the fixed points is drawn, and the intersection point where the lines intersect is defined as the position of the pillar mounting hole. However, it is difficult to determine a fixed point by such a method since the entire outer periphery of the lower part of the pillar 1 of the starting step 1 and the decorative handrail 2 are almost curved. It has been difficult to precisely mark the positions of the plurality of pillar mounting holes on the mounting portion 1a and the decorative handrail 2 so that the mutual positional relationship is completely identical between the two.

[0006]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art, and makes it possible to completely align the positions of the pillar mounting holes in the lower part of the pillar of the starting step and the decorative handrail so that the mutual positional relationship between them is completely the same. It is another object of the present invention to provide a means which can be used for a precise marking, and which can be used in common even when the starting step is used for a plurality of kinds of decorative handrails.

[0007]

Means for Solving the Problems The present inventor has conducted intensive studies in order to solve the above-mentioned problems, and as a result, has found that the mounting position of the lower part of the starting step and the mounting hole of the pillar in the decorative handrail, which constitute the lowermost step of the wooden stairs, are designed. In order to accurately mark the handrails, a plurality of types of decorative handrails shall be used, with the pillar lower mounting part at the end of one starting step in the completed mounting state and the mounting hole position of the main pillar being common. Use a precision mark sheet drawn on a translucent or more transparent sheet in one plan projection so that the handrail and the mounting hole position of the child pillar when it is used can be identified for each decorative handrail. After exploring what was good, the present invention was completed.

A detailed description will be given below of the sheet for precision marking at the position of the mounting hole for the stair climbing pole according to the present invention with reference to the drawings. FIG. 2 is a front view showing an example of the precision mark sheet at the position of the stair climbing port post mounting hole according to the present invention. The sheet 5 for precision marks at the position of the stair climbing pole post mounting hole according to the present invention has the same shape as the pillar lower mounting portion 1a at the end of the starting step 1 that constitutes the lowermost step of the wooden stairway ramp. A plurality of different types of decorative handrails, for example, two types of decorative handrails 2 and 2 ′ (in the illustrated example, a spiral shape and a circular arc shape) are combined as decorative handrails to be positioned above the lower column mounting portion 1a of the step 1 The state in which each pillar is correctly attached and completed is depicted in one plan projection view as follows.

In other words, only one pillar lower mounting portion 1a of the starting step 1 and the mounting hole position P of the main pillar 3 are common to each combination, and only one is drawn. The decorative handrails 2 and 2 'and the mounting hole positions Q and Q' of the child pillar 4 when they are used can be identified separately for each of the decorative handrails 2 and 2 '. Is drawn with a solid line, and the other decorative handrail 2 'is drawn with a line that can be distinguished individually such as a dashed line. These column mounting hole positions P, Q, Q 'are represented as intersections of two lines as shown. These pillar mounting hole positions P, Q, and Q 'are indicated by the positions of the central axes of the pillars 3 and 4 in a state where the pillars 3 and 4 are mounted.

The lower portion of the main pillar 3 is provided with a step so that a portion penetrating the lower portion mounting portion 1a of the starting step 1 may have a smaller diameter than a portion above the lower portion. In some cases, it is fixed to the floor. Even in such a case, it is necessary to mark the penetration position of the lower pillar mounting portion 1a as the mounting hole position P of the main pillar 3 in the same manner. Generally, a cylindrical projection for mounting is provided at the upper end or lower end of each of the columns 3, 4, and a circular hole for fitting the projection is formed on the upper surface of the column lower mounting portion 1a of the starting step 1. A small circle as shown in the figure may be drawn around each of the mounting hole positions P, Q, and Q 'for convenience when drilling on the lower surface of the decorative handrail 2.
The sheet used for drawing the plan projection view should be at least translucent or transparent. The precision mark sheet 5 at the position of the stair climbing port post mounting hole according to the present invention may be configured as a single-sided adhesive type or a double-sided adhesive type so that it can be seen from the opposite side when the release sheet is peeled off.

If the precision mark sheet 5 is of a single-sided adhesive type or a double-sided adhesive type, the position can be easily fixed by sticking it with the adhesive. Means such as applying an adhesive to the surface of the step 1 in contact with the lower column mounting portion 1a may be used. Next, in this state, the position P of each pillar mounting hole of the master pillar 3 and the slave pillar 4 is set.
And the position of Q or Q '(whether Q or Q' is used as the decorative handrail 2 or the decorative handrail 2 ') is marked with a nail or the like from above the precision marking sheet 5. In some cases, a through hole for mounting the main pillar 3 is previously formed in the lower pillar mounting portion 1a. In this case, the position P of the pillar mounting hole of the precision mark sheet 5 must match the through hole. Prioritize.

Further, in order to mark the lower surface of the decorative handrail 2 or 2 'using the precision mark sheet 5, firstly, the decorative handrail 2 or 2' to be drawn is drawn through the precision mark sheet 5 through it. The position of the precision mark sheet 5 is fixed by matching the shape of 2 ′ to the decorative handrail 2 or 2 ′.
Will be used upside down when marking on the pillar lower mounting portion 1a). If the precision mark sheet 5 is of a single-sided adhesive type or a double-sided adhesive type, the position can be easily fixed by sticking it with the adhesive. Means such as applying an adhesive to the surface on the side in contact with the mounting portion 1a may be used. Then, in this state, the respective column mounting hole positions P and Q or Q 'of the main column 3 and the sub column 4 as in the case of the column lower mounting portion 1a.
(Depending on whether the decorative handrail is the decorative handrail 2 or the decorative handrail 2 ′, the position of Q or Q ′) is marked with a nail or the like from above the precision mark sheet 5.

By the operation described above, the mutual positional relationship between the marked various mounting positions P, Q or Q 'is determined by the mounting portion 1a of the lower column of the starting step 1 and the decorative handrail 2,
It is completely coincident with the lower surface of 2 '.
