DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to, for example, when constructing a wooden staircase in a general house, the height of a riser in the staircase, the position of a stepboard corresponding to the width of a tread, the position of a riser, and the like are provided on the side girder surface. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a staircase working black ruler which can be displayed and filled in easily and in a short time and can perform work quickly, and a staircase making method using the ruler.

[0002]

2. Description of the Related Art When a wooden staircase in a general house is constructed and constructed, a predetermined operation corresponding to a straight staircase having a straight-line staircase structure or a rotating staircase having a turning portion is performed. In the construction of the straight staircase, there is a method of performing sanitization in which a dimension line or the like is written on the surface of the side girder based on the original size drawing created as the first method. Also,
As a second method, a small split material is laid between the frame on the upper floor and the floor on the lower floor to measure and measure the horizontal angle of the step board, and on the side of the side girder, one side edge thereof is almost the same. A reference line parallel to, for example, about 6 cm apart is blackened, and the kick-up height corresponding to the horizontal angle of the stepboard based on this reference line,
There is a method in which the width of the tread surface is set, and the upper surface position of each step board and the side surface position orthogonal thereto are sequentially blackened from one of the upper and lower portions. However, in the second method, even if it is usually performed using a curved scale, it is very troublesome. Therefore, a form plate is formed from a thin plate material, and the form plate is applied to the side-girder surface to sequentially perform black ink. Put on. Furthermore, as a third method, the height from the floor on the lower floor to the frame on the upper floor is measured and divided by the number of steps, and the horizontal distance from the frame to the first side of the stairs. Is divided by the number of steps to obtain a tread width, and there is a method in which black ink is sequentially applied based on the reference line applied in the same manner as in the second method.

[0003] In the construction of the turning stairs, as a first method, without using the side girders, a turning step board is placed on a joist that is mounted by being bridged between columns, and nails are attached. Stop it. That is, while attaching the turning step plate to each of the notch-formed notch-formed step plate placing recesses, attaching the straight-running portion, and incorporating the riser plate, the turning around the side so that the side girder appears on the side of the turning portion. A side spar for makeup in which a portion of a step board is cut into a cut shape is inserted. Second
In the case of attaching the side girder in the turning part as the method described above, the side girder of the straight stairs is blackened as described above, and subsequently the side girder of the turning part is blackened. Third
The method is performed based on the full scale drawing created as the method described above. After the straight section is constructed, the full scale drawing of the surrounding area is created, and according to this full scale drawing, the tread width of the first step, the kick-up height, and the second step The width of the tread surface, the height of the rise, and the dimensions of the upper one are measured in order, and a drawing is created.After the drawing is made, a shape plate is made by this, and the shape plate is transferred to the side beam surface. Inking is performed.

[0004]

However, according to such a conventional method, it is not only difficult to secure a place for creating a full-scale drawing in the first method in the case of constructing a straight staircase, but also extremely troublesome. It hangs. Second and third
According to the method of (1), a house is built, and actual measurement cannot be performed unless the floor is stretched and a frame is attached. Therefore, it is difficult to manage the work procedure. In the third method, calculation is performed after calculation. It is easy for mistakes in points to occur.

[0005] In the first method for fabricating a rotating staircase, it is easy to place and fix the step board on the joist, but it is possible to grind the step board portion of the decorative side beam into a cut shape. Not only is it difficult to form the ink, but also the appearance is deteriorated due to the formation of a gap due to the later insertion. In the second method, the setting of the rise height and the width of the tread width are not easily determined, and it is time-consuming and troublesome to repeat the operation many times, and even an unskilled worker can use this method. There was something I couldn't do. In the third method, it takes time and effort to create and transfer a full scale drawing, which is extremely troublesome.

Accordingly, the present invention has been made in view of the above-mentioned circumstances that have existed in the past, and has been developed in consideration of the above-described circumstances.
Accumulation work indicating the mounting position of each riser can be performed accurately and quickly, and it is possible to easily and clearly indicate the mounting position of not only straight stairs but also flat L-shaped, U-shaped, etc. It is an object of the present invention to provide a staircase working black ruler that can be carried out in any direction, below and above, and that can significantly reduce the working time, and a method of making a staircase using the ruler.

In the drawings, reference numeral 1 denotes a ruled staircase with black stairs. And a rising dimension indicating section 4 that also sets the rising height y are formed substantially integrally with each other so as to be substantially orthogonal to each other and to have a substantially L-shaped plane as a whole. At least usually, a number corresponding to the number of steps when constructing the stairs is provided.

[0010] The tread dimension indicator 2 itself is formed in a strip shape of an appropriate width having a length which is not shorter than at least the tread width x of the stairs to be formed. A slit-shaped tread surface adjusting slot 3 is formed along the slit, and a dimensional scale is displayed on the front and back surfaces.

[0011] Similarly, the rising dimension indicating section 4 itself is formed in a strip shape of a suitable width having a length which is not shorter than at least the rising height y of the stairs to be constructed. A slit-like rise adjustment slot 5 is formed along the direction, and a dimensional scale is displayed on the front and back surfaces.

The ruler 1 with stairs is placed on a predetermined side girder (11) surface, and the tread surface dimension indicating section 2 and the riser dimension instructing section 4 of the stairs black ruler 1 are tread surface position and rise position. In order to automatically set the step width at the time of the entry display, the width of the tread surface dimension indicating section 2 is set to substantially correspond to the step width.
The width of each of the kick-up dimension indicating sections 4 is set and formed.

The ruled bodies 1 with stairs are connected to each other by ruler body connecting means 6, and the ruler body connecting means 6 itself is a tread surface dimension indicating section 2 of one of the ruled bodies 1 with black stairs. Alternatively, a riser dimension indicator 4, a ruler stopper 7 that is overlapped with a substantially perpendicular overlapping portion of the tread surface dimension indicator 2 or the riser dimension indicator 4 of the other staircase black ruler 1, and a tread adjustment slot 3 mutual or rise adjustment slot 5 mutual, tread adjustment slot 3,
A screw stopper 9 that slides along each of the rise adjustment slots 5 so that the fixing position can be adjusted so that the fixed position can be adjusted, and thereby the rulers 1 with stairs are connected via the ruler stopper 7. And comprising.

The ruler stopper 7 itself is used as the tread dimension indicator 2.
Alternatively, a pair of strips having a width substantially the same as the width of the riser dimension indicating section 4 are formed in a plane so as to be substantially L-shaped so as to be orthogonal to each other, and a wing nut as a screw stopper 9 is provided on each of the strips. The male screw 8 to be screwed is formed in a standing shape in a pair.

The screw stopper 9 is a nut having a butterfly-shaped portion. As shown in FIG. 1, the ruler stoppers 7 are disposed vertically below the stairs-inked rulers 1 so as to sandwich the rulers 1 as shown in FIG. While the male screw 8 penetrates the overlapped staircase black rulers 1, the wing nuts (9) arranged above these are screwed into the male screw 8 so as to sandwich the staircase black rulers 1. To conclude. Note that the configuration of the ruler body connecting means 6 itself is not limited to the illustrated example.
It is designed to be as close as possible to the surface, so that there is no error in the blacking work of writing and displaying the tread surface position and the rise position.

When a predetermined staircase is to be constructed, the width of the tread surface x and the height y of the rise corresponding to the number of steps are dimensioned on the surface of the side spar 11 and the blackboard is applied. The riser 13 is cut into a groove shape, and the end is cut off so as to correspond to the floor surface or the frame or to the mutual connection, and the step board 12 and the riser 13 are assembled. Next, a description will be given of the actual blacking work for dimensioning performed by combining the plurality of staircase blackened rulers 1 and the ruler body connecting means 6 at that time.

In the case of a straight staircase, as shown in FIG.
A plurality of stitched black rulers 1 corresponding to the number of steps are connected in a zigzag manner through ruler connecting means 6. That is,
The tread dimension indicator 2 has a length corresponding to the tread width x and the riser dimension 4 has a length corresponding to the rise height y. The variable black ruler 10 for the straight side girder is produced by overlapping the riser dimension indicating part 4 of the staircase black ruler 1 with the ruler stopper 7 and the screw stopper 9 at the overlapping portion. And the side girder 11 inclinedly arranged between the lower floor and the upper floor corresponding to the stairs gradient.
A reference vertical interval P set on a vertical line (standing water) from the upper corner of the upper edge of the upper side edge, and drawn in parallel with this upper edge along the upper edge of the side beam 11 in relation to or independently of this. The corner portion of each of the staircase-inked rulers 1 is aligned with the reference line L thus set, and is placed on the surface of the side beam 11 (FIG. 2).
(A)). Next, after marking the tread surface position along the outer edge of the tread dimension indicator 2 and the kicking position along the inner edge of the kick dimension indicator 4, the stairs blackened ruler body 1
Each is removed from the surface of the side beam 11 (see FIG. 2B).
Then, the thickness of the step board 12 and its wedge 14 are determined based on the tread surface, and the riser 1 is determined based on the rise surface.
After displaying the thickness 3 and the wedge shiro 15 by black ink, respectively, the groove of the step board 12 portion and the riser 1 portion are cut off.
Further, a frame fitting portion F that meshes with the frame on the upper floor and a rising portion C with the floor surface on the lower floor are cut (see FIG. 2C).

In the case of a rotating staircase, as shown in FIG. 3, the upper and lower sides are straight portions, and the surrounding portion disposed in the middle is a plane L-shape that bends at a substantially right angle, and as shown in FIG. A description will be given of a case where the side is a straight traveling portion, and the surrounding portion disposed in the middle is a plane U-shaped bent substantially in the opposite direction.

With respect to the features in the plane L-shaped staircase, for example, an L-shaped staircase having a three-step swirl portion will be described. That is, as shown in FIG. 3 to FIG. 8, groove cutting for fitting the step plates 41, 52 to 52 and the riser plate 55 formed on the surface of the side girders 31, 32, 33 arranged outside the surrounding portion. The processing position is determined by the variable black rulers 61, 64 created by combining the ruler with black stairs 1 and the ruler body connecting means 6.

First, a full-scale plan view of the L-shaped staircase is created on the surface thereof using, for example, a veneer board at the site, and the length of the staircase section from the upper floor edge to the lower floor surface is calculated as follows: The number of steps, the tread width x, and the rise height y are set in consideration of the number of steps, the tread width x, and the relationship between the rise height y according to each of the stair area heights (floor heights) between the upper floor and the lower floor. That is, the height of the stair area is obtained by multiplying the number of steps and the rise height y, and the length of the stair area is obtained by multiplying the number of steps and the width x of the tread surface. The number of steps, the rise height y, and the width x of the tread surface in the straight traveling portion are set. The original plan view at this time is shown in FIG. 3, and in this original plan view,
6, the arrangement of the wall 20, the side girders 31, to 34, the step plates 41, to 52, etc. are displayed as they are in actual size. The tread widths (a, b, c, d) of the plates 46, 47, 48 are displayed as they are. As shown in FIGS. 3 and 4, the lower straight-side girder 31 in the lower straight-line portion continuous to the lower floor, linearly continues above the lower straight-side girder 31, and extends outside the surrounding portion. , The lower turning girder 32 located at the lower side, the upper turning girder 33 continuous at right angles to the upper part of the lower turning girder 32, and located on the upper side outside the turning part, and the upper turning girder A series of frame side girders on the outer side of the stairs are constituted by an upper straight side girder 34 linearly continuous at the top of the upper part 33, and a lower straight side girder 31 having a five-stage configuration and an upper straight side having a four-stage configuration. Since each of the beams 34 is a straight portion, the beams are symmetrically arranged on the left and right. Unless otherwise specified, the description of the construction procedure will be directed to the side girders 31, 34 arranged on the outside in the surrounding portion.

When the original plan view is created in this way,
The turning side girders 32, 3 in the turning portion on this full scale plan view
By measuring the lengths of the outer edges at the positions of the three step plates 46, 47, and 48 on the three surfaces by actual measurement values, the step plate 4
The tread width a is obtained at the position 6, the tread widths b and c are obtained at the position of the step 47, and the tread width d is obtained at the position of the step 48.

Next, as shown in FIGS. 5 (A) and 6 (A), step plates 41, 45 in the lower straight side girder 31 and step plates 49, 45 in the upper straight side girder 34, which are straight portions, respectively.
In order to display the respective arrangement positions, a predetermined number of staircase-inked rulers 1 and ruler body coupling means 6 are combined with a predetermined number of staircase-blackened rulers 1 in the same manner as the straight-line spar 11 in the straight-line stairs, and the lower straight-line spar 31 is displayed.
The variable black ruler 61 for the lower straight side girder having the six-stage configuration in the portion and the variable black ruler 64 for the upper straight side girder 34 in the five-stage configuration in the upper straight side girder 34 are manufactured. At this time, the crossing position of the tread size indicator 2 of one of the stitched rulers 1 combined with the riser dimension indicator 4 of the other stitched ruler 1 is determined by the set tread width x, It is assumed that it corresponds to each rise height y. The variable black ruler 61 for the lower straight side girder is disposed on the lower straight side girder 31 and the variable blacker ruler 64 for the upper straight side girder on the upper straight side girder 34. The reference line L on each of the straight girder 31 and the upper straight girder 34
The corner portions of the staircase-inked ruler body 1 are aligned with each other so as to be aligned with each other, and are placed on the surfaces of the lower straight side girder 31 and the upper straight side girder 34. Then, after marking the tread surface position along the outer edge of the tread dimension indicator 2 and the kicking position along the inner edge of the kick dimension indicator 4, the respective variable black rulers 61, 64 are moved downward. Straight side girder 31, Upper straight side girder 34

Is applied to a frame fitting portion F that meshes with the frame 30 on the upper floor in the upper straight side girder 34, and then the step board 41,
４５45, 49, ５２52 and the riser 55 are grooved, and the rising part C and the frame fitting part F are cut.

At this time, one step above the uppermost step board 45 in the lower straight side girder 31 is located at the position of the lowermost step board 46 in the surrounding portion, and this portion coincides with the position of the column 23, and , Is connected to the lower end edge of the lower turning girder 32. Therefore, at the position of the step board 46 which is a continuous portion of the lower straight side girder 31 and the lower turning side girder 32, the black line is drawn along the direction directly above the tread surface edge of the step board 46. Then, the actual size up to the position where the lower straight side girder 31 intersects the upper edge is measured, and this is set as a reference vertical interval P (see FIG. 7C).

Similarly, one step below the lowermost step board 49 in the upper straight side spar 34 is the position of the uppermost step board 48 of the surrounding portion, and this portion matches the position of the support 25, and The upper spar 33 is continuous with the upper edge. Therefore, it is located at the position of the step board 48 which is a continuous portion of the upper straight side girder 34 and the upper turning side girder 33, and from the position where the tread surface of the step board 48 intersects with the reference line L, is located directly above the tread surface. The actual size up to the position where it crosses the upper edge of the upper straight side girder 34 is measured on a line marked along the direction, and this is set as a reference vertical interval P, and cutting is performed along this (see FIG. 8 (C)).

The lower straight-movement side digit 3 which is the straight-moving portion thereof

Regarding the blacking work on each of the upper straight side girders 34, there is almost no relation to which is performed first, but only the upper straight running with the lower turning side girder 32 which is the upper part of the lower straight side girders 31. It is important that each continuous portion of the side beam 34 and the lower side upper beam 33, which is the lower portion, is set precisely.

As shown in FIG. 7, the blacking work on the lower turning girder 32 is performed at the outer edges of the tread surfaces of the step plates 46 and 47 obtained on the previously created original plan view. The tread widths a and b, which are the respective lengths of
The variable black ruler 62 for the lower turning girder is produced by setting the tread surface dimension designating section 2 in the step 2 through the ruler body connecting means 6.
