Description

[Detailed Description of the Invention] This invention relates to a ruler that performs the role and marking of stairs in all buildings, and more specifically, the scale of stair regulations in Article 23 of the Enforcement Order of the Building Standards Act, and By rationally combining the improved method of rectification, which is the source of the technology, and the three methods of power division using protractors, we can not only perform conventional step division and marking, but also complex calculation methods no matter how the stairs are deformed. without the need for
It concerns the role of stairs and a ruler that is used for easy marking. As long as buildings are constructed in accordance with the Building Standards Law Enforcement Ordinance, they can be freely designed and constructed within a designated site. Therefore, if a staircase is to be built inside the stairway, it must be constructed based on the stairway regulations in Article 23, Article 24 of the Enforcement Ordinance, based on the stairway installation area, and that is most practical and adaptable to modern lifestyles.

In addition, in order to make the most of the expensive site, construction costs and tsubos are limited, and in order to make the most of the enforcement ordinance mentioned above, priority is given to the floor plan, which often threatens the designated area for installing stairs. It will be done.

Stairs are a part of building construction work that requires a high degree of technical skill, and they are also an important passage connecting the downstairs and the upstairs. In addition, when it comes to special decorative stairs, the work becomes even more complicated and involves difficulties such as marking.
Furthermore, if the site changes, the building will also change. Therefore, the stairs built inside are often deformed, and deformed stairs are bound to be extremely difficult work. On the other hand, in a world of hugely changing social life, the large architecture industry that directly deals with staircases is a place where the three major principles of human life are
Although it is a fundamentally important occupation that provides ``shelter'' for food, clothing, and shelter, there are few public institutions to support it, and it receives little benefit from society, so it has to deal with everything with its own resources, and while protecting its own life, it also has to do with its professional life. It is a profession that requires mastering the discipline of ``sashigane'' applied technology, which is difficult to understand from the standpoint of one's position, and constantly making efforts and research to improve architectural technology. Furthermore, the construction industry is a profession that requires advanced technology and harsh labor, but it is also a fateful profession where you cannot get much more than a low salary.There are only 0 people who can praise the achievements of their ancestors and have no time to learn even the basic techniques. It is clear that if we spend our days in vain, it will cause defective construction even in staircase construction, which will lead to longer construction periods and higher construction costs. The vertical height and horizontal length of stairs vary depending on the building, up to a certain level.
Depending on the total number of tiers with a specified width and thickness on the hypotenuse surface connecting the varying heights and lengths, carve into the side panels or exposed girders to create the downstairs part or irregularly curved part. There are also stairs that are built into the bottom, middle, and top steps of the stairs to change the direction of elevation. Depending on the purpose of use of the stairs, the width of the stairs and dance floor, the dimensions of the risers and treads, etc. shall be determined according to the Building Standards Act Enforcement Ordinance No. 2.
The types are determined by regulations in Article 3, Article 24. The present invention is designed to enable accurate and quick marking of roles and markings on any staircase based on the enforcement order, without requiring particularly complicated calculations, in view of the construction conditions and construction obstacles of stairs. As a result of intensive research and ingenuity, 5 pieces with different shapes and purposes were created.
It was discovered that the performance of the ruler of the member can be fully demonstrated and various problems regarding marking the role of stairs can be solved all at once. Accordingly, an object of the present invention is to provide a ruler that allows easy marking of the role of staircase construction, which is absolutely necessary for modern and future buildings.

In order to achieve the above purpose, the shape and scale of this ruler will be explained in detail.

5 is removed. Therefore, when the free fork part 15 is installed between the opposite parts of IL1λ, the protruding part 3 of the tread length part 12 is removed.
Since the free scale part 15 has priority in 1, the direct upper scale s11 is separated from the protruding part 31 and loses its squareness, and is centered on the pin member 27.It becomes the free scale part 51, and the top of the stair mark has a stable slope of the step, and the diagonal kick. It is possible to mark and adjust features such as wedges and margins.

Next, the ruler 100 for dividing and marking steps of stairs according to the present invention will be described in detail below by giving a preferred example and referring to the attached drawings. (6) Fig. 2 is a basic combination diagram of the ruler 100. , ruler 1
The combination of 00 can be freely left and right, and the principle is to align the scale used for either the metric scale or the shaku dimension scale with the inside of the evanescent part 11 and the tread shaku part 12, which are combined at right angles.The 0 figure is the left combination. A scale scale will be used. First, place the pin member 27 held in the intersection hole 26 of the tread scale part 12 on the left side, with the scale dimension scale at the horizontal upper end, and the diversion part 11 vertically and the dimension scale on the right side, and the intersection hole. The pin member 27 of the tread edge portion 12 is fitted into the side surface of the pin member 27 of the tread edge portion 12 through the horizontal groove No. 37 and tighten the pin member 27, the 8% diameter portion of the two-stage shaft portion of the pin member 27 will fit vertically into the intersection hole 26 of the tread shank portion 12 and the intersection hole 26 of the diversion portion 11. The fitting is completed at the same time, and an accurate square ruler is formed. Next, the front side plate part 16
The distal end 39 of the back stepped section 17 and the distal end 23 of the fabric part 11 form the oblique side of the folded section to form a right triangle, and the basic integration of the ruler 100 is completed.

Figure 3 shows an example of the 5th floor high step division method.Detailed dimensions of some stairs are written in the design drawings, but in reality there are various problems and it is not possible to deliver the stairs according to the drawings. There are things that don't happen @
It is certain that the actual dimensions are taken on site before the work is started. Therefore, the use of the ruler 100 is directly carried out on the work site or in the work place to divide and mark the steps of the stairs. The constructor can work easily and quickly, and by applying "Sashigane", which is always available, the number of steps and riser dimensions can be easily determined based on the above-mentioned enforcement ordinance without the need for calculation. .

As a principle of the role method of this ruler 100, minus 1 of the number of stairs. The number of berths on all floors shall be the same. Furthermore, the number of steps divided by the step division scale of the 5-step dividing scale section 17 on both step sides is subtracted by a constant 1 shaku, and the remaining fraction is 1! Arrow-shaped scale 3.5 of Article 23 of the Enforcement Order applicable to Sll or tread scale part 12
' By aligning the lower end of the ``sashigane'' with 935.48, the number of steps and the dimensions of the top and tread are determined at the same time.

(8) Example The height of the floor is 9 shaku 5 sun (2
8,79) The scale is 9 sun 5 minutes (scaled at the leg dimension scale 52 of the vertical side of the right triangle 11).
28, 79) is measured from 0 sun 53 to 54, 0 sun 55 of the role opposite part 17 corresponding to the hypotenuse, floor height dimension scale -
According to 54/54 of 9 sun, when divided into 14 steps, role opposite part 17
01 shaku 4 inch scale 56 is the low side tread shaku part 12
Align the pin member 41 of the first step dividing scale part 17 with the upper end 57 of the foot dimension scale of both members 11, 12. At this time, the scale of the tread part 12 is irrelevant, and the upper end is only used as the lower side of the triangle. Insert the wife and child 59 of the ``sashigane'' in the middle, and according to the principle of the function of this ruler, subtract 1 shaku constant from the number of steps to be inserted, and adjust the remaining fraction to 4 sun, or 61, and at the same time, adjust the lower end of the ``sashigane'' to 61. The riser dimension 62 is determined if it is below the arrow-shaped scale "Jyuin" (maximum 230 directly above the residential stairs). It will be 6 sun and 8 minutes.

(9) Fig. 4 Example An example of Kaitero method The scale-i-dimension 8 sun 5 minutes (25, 76) at the two-shaku dimension scale 57
Measure out from 0 sun 53 and set it as 56 ◇ Match the reciprocating scale vo size 58 of the role anti-section part 17 corresponding to the hypotenuse, and the floor dimension scale 108-sun 56, and when the role anti-section part 17 is divided into 13 steps. 11.12. Counting from 0 dimension 58, align the 1 shaku 3 dimension scale 59 with the inside 54 of the leg dimension scale of the vertical side of the opposite part 11, and then move the pin member 41 of the role reverse part 17 to 11.12. Tighten it close to the opposite sides of the At this time, the scale of the vertical part 11 is irrelevant, only the inside is used as the vertical side, and the lower end of the tread part 12 is attached to the entire long length 60 of the part.
Insert the wife and child 59 of the ``sashigane'' into the middle of a17, and at the bottom end, subtract 1 shaku constant from the number of steps according to the principle of the wooden ruler role method, match the bottom edge of the ``sashigane'' to the remaining fraction, and at the same time insert the tread shaku section. The tread dimension 63 is determined if the lower end of the stylus is at least 15 cm above the arrow-shaped scale, which corresponds to the stair regulation tread dimension in Article 23 of the Enforcement Order of 12. Therefore, the determined tread size will be a little over 6 sun and 5 minutes.

(+01 Fig. 5 Example Straight staircase marking method, mark the reference ink 65 at a predetermined position on the side plate 66, and mark the oblique side of the right triangle of the ruler 100, front and back 16.17 of the side plate 66.
6, loosen the joining pin member 41, and measure the riser dimension 6 sun 8 minutes with the foot dimension scale 52 from the 0 sun 53 of the vertical side of the opposite part 11, 62, and the lower side. From the 0 dimension 53 of the tread scale part 12, the foot dimension scale 57
When the tread dimension 6 x 5 minutes 63 is accurately aligned with the reference marking 65 and the combining pin member 41 is tightened, the preparation for marking the straight staircase is completed. When the upper end 57 and lower end 64 of the tread part 12 are marked, the position and thickness of the tread plate are determined (regulatory product tread plate thickness dimension is 3.3 cm).
If a predetermined dimension is marked from the contact point 62 with the reference mark 62, the front surface of the step board is determined, and if the outer side 67 is marked, the front surface of the riser board is determined. (1M, when threading a board, cut a groove to the specified thickness on the front reference.) If you align 62 and 63 with the reference mark 65 in sequence and feed them and mark them as described above, straight staircase marking will be completed accurately and quickly. .

(111 Fig. 6 Implementation drawing Circular stair tread step division method. Black out the actual size of the part that goes around the specified floor surface and the same dimensions as the part that goes around, and then black out the horizontal markings 68 and vertical markings 69 that serve as the reference for the turning part. Align the intersection hole 26 of the tread part 12 of the ruler 100 with 70, and temporarily fix it with small nails through the temporary fixing holes 2829 at both ends 19° and 20. In use, align the hole 33 of the diagonal scale part 13 and insert the lateral groove 4 of the diagonal part 11 directly above the side surface of the pin member 27 held by the tread scale part 12.
Assemble using 7 and tighten the pin member 27 slightly to complete the preparation. At this time, since the protruding portion 48 of the tread length portion 12 is not used, the right-upward portion 11 rotates around the pin member 27.

This becomes the opposite part 50 of the frequency meter needle. Therefore, the tread steps are at both ends 21,23. Angle confirmation notch 22 in
．． 24. At 22, align the scale on the power side of the power scale part 13. o When the 90 degree three-stage division is used, align the scale 9 o 0 ÷ 3 sequentially with the angle confirmation notches 22, 24.
If you mark it on the actual size, it can serve as a circular staircase with the same dimensions at the correct angle.

□□□) Fig. 7 Example Modified stair tread step division method, marking out the actual size of the part that bends to the specified floor surface.

Create an intersection by marking the horizontal marking 68 and the vertical hanging 69, which serve as a reference for the bending part, and then marking the bending part from that intersection. Intersection hole 26 of the tread scale part 12 of the ruler 100
i 70, temporary peg holes 28.29. at both ends 19.20°. Temporarily fasten with a smaller needle and use the protrusion 31.
The hole 33 of the power scale part 14 is assembled together, and the tread scale part 12 is assembled.
When the pin member 27 is assembled from the side surface of the pin member 27 by using all the lateral grooves 47 of the vertically opposite part 11, and the pin member 27 is firmly tightened, the preparation is completed.
Since the thickness of the dioptric scale part 14 has priority over the protrusion of $48 of 2,
Frequency meter needle opposite part 50 rotates around pin member 27
becomes.

Therefore, the power measuring part 50 is rotated around the bending part, and both ends 2
1.23.0 Notch 22.24. In addition, looking at the modified staircase power scale, the angle of the bend was determined to be 30 degrees.

At this time, as a general rule of the modified stair tread step dividing method and the usage of the ruler 100, the angle of the first step of the curved portion is determined by subtracting the remaining angle from the total angle of 90 degrees of the curved portion. Therefore, in this figure, 90 degrees - 30 degrees = 60 degrees, and the first stage of the one-turning portion is 60 degrees from the horizontal reference 68. When the counter part 50 of the power meter needle is rotated to match 60 degrees, the curved part becomes 90 degrees, and the curved part 60 degrees can be divided into two tread steps. The regulatory dimensions for roundabout stairs are 15 cm or more at the 30 cm distance from the narrowest side of residential stairs (22.5 cm when measured in angle).
Figure 8 Example: Diagonal riser marking method A reference ink 65 was inked at a predetermined position on the side plate 66, and it was combined into a right triangle.
Basic marking is done using the riser and tread dimensions determined using the ruler 100. At this time, mark 71 at the bottom of the outside 67 of the right side part 11, that is, at the front of the riser, where it intersects with the step board.
When the pin members 41 and 27 of the ruler ioo are loosened and the free hole part 15 is inserted between the right-up side part 11 and the tread edge part 12, the free hole part has priority for the protruding part 31 of the tread edge part 12. As a result, the straight upward reversal portion 11 loses its squareness and becomes a free meter reversal portion 51 centered on the pin member 27. It is possible to perform mark adjustment markings on markings. To mark the riser diagonally, use the loosened ruler 100 of the pin members 41 and 26 marked above.
When the inner side 0 sun 53 of the straight upward facing part 11 is aligned with the intersection 71 between the front surface of the riser and the step plate, the tread square part 12 moves horizontally and loses its squareness. Standard black 6
Align the top with the intersection of 5 and riser dimension 62, and set 0 dimension 53 to 7.
The diagonal lines lined up with 1 will be the front of the diagonal riser.

(3) The riser part has a horizontal groove in a hole of the same diameter at the same position as the intersection hole at a predetermined position of the tread part, so that it can be fitted from the surface of the pin member of the tread part. The basic combination of this ruler is to align the metric scale or shaku size scale (which is used when combined on either the left or right) with the tread part at the lower horizontal end, the riser part facing vertically upward, and the protruding part 4. A ruler according to any one of claims 1 to 3, which when combined in use constitutes a precise right angle ruler. (4) When the power scale part is incorporated between the riser part and the tread part that make up the right angle ruler, the power part has priority over the protrusion part of the tread part, so the riser part has priority over the protrusion part. A power gauge needle that loses its squareness and rotates around the pin member, and divides steps in degrees without the need to calculate the role of the treads of rotating stairs and deformed stairs on a flat surface according to the power scale of the power scale. 5. A ruler according to any one of claims 1 to 4, which measures the inclination of the stairs, whose riser and tread dimensions have been determined, in degrees. (5) The scale and shape of the scale part are the radius of a perfect circle with a diameter of 15 cm.The center part has a hole at the intersection of the tread part and the riser part, so that it can be smoothly assembled between the tread part and the riser part. A semi-circular notch is removed at the same position as the protruding part near the part. Therefore, the power scale part and the tread scale part are combined by providing a hole with the same diameter and at the same position as the protruding part of the tread scale part at a position of 10 cm from the center of the hole. When dividing the role dimension, there is no need to calculate the step division, and the tread step division scale is written in degrees.The scale can be divided into 2 steps, 3 steps, and 4 steps around 90 degrees, and can be moved to the left or right. 180 degree rotation of 5, 6, 7 and 8 steps can be freely moved left and right. The power scale on the back of the power scale part is an irregularly curved 180 degree scale that can be used to calculate the tread dimensions of the curved part of the tread step in the plane of the deformed staircase without the need for step calculation. The ruler according to any one of claims 1 to 5, wherein the angle of the curved part is subtracted from 90 degrees, and the remaining degree is 90 degrees from the curved part. (6) The total length of the side plate is 64 cm, the width is 3.3 cm, and the thickness is 5 m.
/m, and the two other ends of the right-angle ruler are held together via two pin members to form a right-angled triangle. shaku size 1 shaku 2
The sum of the square of the tread scale (36.36) and the 1 shaku 2 sun (36.36) of the scale of the tread scale is calculated, and the square root thereof is determined by the step division scale of the back scale of the side plate scale. Therefore, the step scale on the back side of the side plate is 1 shaku 6 sun 7 minutes rin (51.420) of the square root of the required square root, but the scale is 1 shaku 7 sun (51.420).
51), and the scale on the surface of the side plate, which is a reciprocating scale that can be measured from both ends of the side plate, is in the metric system 51.
51 cm, and the hypotenuse dimension of the already determined riser dimension and tread dimension can be immediately determined. Furthermore, measure the determined floor height dimension using the scale of the riser section at a scale of 1/10, measure the floor dimension (lowered length) using the scale of the tread section at a scale of 1/10, and measure the floor height dimension at a scale of 1/10 using the scale of the tread section. The length dimension connected to the hypotenuse on the scale is 1/10 of the length of the side plate, and when multiplied by 10, it becomes the actual length of the side plate, which makes it possible to immediately know the dimension without calculation. A ruler described in any of Section 6. (7) When a free shank part is incorporated between the riser part and the tread part of this ruler that forms a right triangle, the free shank part has priority over the protruding part of the tread part, so the riser part is It separates from the protruding part and loses its squareness, becoming a free measuring part centered on the pin member, and the right triangle transforms into a scalene triangle. 8. The ruler according to any one of claims 1 to 7, which is capable of marking adjustment of steps such as stable slope diagonal riser, wedge margin, etc. on the marking of stairs. (8) This ruler, which has a right triangle shape, can mark the dimensions of the riser and tread by using both the inner and outer sides of the riser and tread length when marking straight stairs. The ruler according to any one of claims 1 to 8, which enables simultaneous marking of basic markings on the front surface of the board, the front surface of the riser board, the upper and lower ends of the step board, etc. (9) Complicated calculations are always required when constructing stairs, but this ruler does not require such calculations at all, and the "sashigane" method can be applied to this ruler within the stair regulation dimensions stipulated in Article 23 of the Enforcement Order of the Building Standards Act. It can be easily determined by doing this. Measure the floor height dimension using the scale on the riser scale at a scale of 1/10, measure the floor dimension (prone length) using the scale on the tread scale, and separately measure the specified steps using the step scale on the back of the side plate. Dividing the hypotenuse into numbers and applying "sashigane", the floor height dimension step division is perpendicular to the riser part, and the floor dimension (down length) dimension step division is wrapped rectangle at right angle from the tread shaku part. Align the inner side of the gable with the fraction of the predetermined number of steps on the side plate shaku portion, and the stair step portions are within the typed riser dimension arrow of the riser shaku portion, and the stair step portions are within the typed riser dimension arrow of the tread shaku portion. If the tread dimension is equal to or greater than the arrow, the lower end scale of the "sashigane" on both shaku sections is the required riser and tread dimension.
The number of steps has already been determined using the step division scale on the side plate. Accordingly, in the ruler according to any one of claims 1 to 9, the number of steps and the riser dimension, and the number of steps and the tread size are determined simultaneously.
