Abstract

PURPOSE:To make easy determination of the length of angle rafter for each slope possible by etching a length scale for corner slope with reference to the length of a flat slope and a length scale of a corner slope with reference to horizontal line in parallel into the shaft of a rule. CONSTITUTION:A tube 2 having a row of scale holes 4a-4j is applied on a shaft 1 etched in parallel with two corner slope length scales with reference to the lengths of flat slope and horizontal line. Slope names are written on a polygonal grip 3 fixed to each end of the shaft 1 and scale marks 5a, 5b are also put on the grip. A slope name is selected by turning the grip 3, a reference point 7 is matched with eave or the angle rafter (front race or wide laths), and then the rule is laid along the slope line of the angle rafter. In case of a 90cm eave of flat slope, scale 90 is marked on the angle rafter with reference to flat slope thus determining a required length of angle rafter corresponding to the length of flat slope (rafter). Length of angle rafter required for horizontal line can be similarly determined by the use of scale in reference to the length of horizontal line.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a ruler used for determining the length of a corner tree in a wooden building in which the eaves of the eaves with slopes, girders, slaps, and small dances can be seen. It is related to the ruler for each slope, which shows the length of the corner tree based on the length of the flat slope and the length of the corner tree based on the length of the horizontal line.

[0002]

2. Description of the Related Art Conventionally, the length of a corner tree has been obtained by the method of squirrels (using the back and front stitches of a pen) based on the length of the horizon (for example, carpenter sculpting technique). reference).

Conventionally, a full-scale drawing was written to obtain the length of a corner tree (the Kodaira raising method based on the length of the horizontal line)

Conventionally, the length of the corner tree has been calculated by a calculation method based on the length of the horizontal line.

[0005]

Conventionally, the method of obtaining the length of the corner tree of the eaves was based on the length of the horizontal line. However, since the carpenter works with the length of the flat slope as the exit of the eaves, the method of determining the length of the corner tree required for the length of the flat slope is the standard of the length of the horizon. The calculation is difficult for beginners.

Conventionally, when obtaining the length of a corner tree, the method of squirting, writing a full scale drawing, or calculating each one has been used, but there is a problem that it takes time.

When the eaves with the length of flat slope are used, the length of the corner tree based on the length of the flat slope is required. The length of the horizon from the girder to the inside, the pillar, etc. In case of, the length of the corner tree based on the length of the horizon is required. The purpose is to quickly find the length of both corner trees.

[0008]

In order to achieve the above object, the ruler of the present invention is based on the scale of the length of the corner slope based on the length 1 of the flat slope and the length 1 of the horizontal line. A cylinder with a hole for viewing the scale is placed on the axis carved by arranging the scales with the length of the corner slope in parallel. It is a polygonal handle with the name of the gradient attached to each end of the axis.

The ruler of the present invention may be made so as to be easy to use according to the scale, but in FIG. 1, the total length is 181 cm, the axis length is 165 cm, the cylinder length is 164.9 cm, and the handle length is 8 cm. Is.

The holes for seeing the graduated scale of the cylinder are set in units of 10 units, and the holes are made to match that. Fine graduations of 10 or less are engraved at the frequently used holes 4h. The size of the hole needs to be long enough to be marked by the number of grade names.

With respect to the polygonal shape of the handle, in consideration of the ease of turning the handle and stability when a ruler is placed, the necessary scales are compared by comparing the marks 8 of the center line written on both ends of the axis with the name of the gradient written. Check if is normal.

Next to the name of the gradient of the handle, "flat" is written on the side of the scale of the length of the corner slope based on the length 1 of the flat slope, and the length of the corner slope based on the length 1 of the horizontal line is written. Write water on the side of the scale to distinguish which is the scale.

The clearance between the shaft and the cylinder and the clearance between the handle and the cylinder may be set so that the handle can be lightly rotated by hand.

The material used for the ruler is stainless steel, aluminum, alloy, plastic, bamboo, wood, etc., and a material with little expansion and contraction is selected for the shaft.

[0015]

The numbers on the scale of the ruler in FIG. 1 represent the length of the eaves with the unit of length in centimeters (for example, the scale 90 is the eaves' length 90 cm).
The length up to 0 is the actual length of the corner tree.

When the corner tree is longer than the scale of the ruler, the ruler may be moved and added.

The ruler can be used by turning the handle to give the required slope name, and aligning the base point of the scale with the position of the tip of the corner tree eaves (the front of Hirokomai) to the slope line of the corner tree. Put a ruler alongside. 90 cm long flat slope
When leaving the eaves, if the scale 90 based on the flat slope is written on the corner tree, the length of the corner tree required for the length of the flat slope (taruki) can be known. If the length of the horizon is 90 cm from the girder to the inside, pillar, etc., the length of the corner tree required for the horizon can be found by writing the scale 90 at the corner based on the horizon length.

Horizontal line length 90 cm with 4.5 / 10 gradient
When leaving the eaves, the length of the flat slope is 98.7.
cm and the length of the corner tree is 133.6 cm (rounded off).

When the eaves with a slope of 4.5 / 10 and a flat slope (taruki) length of 90 cm, the length of the horizon is 82.1c.
The length of the corner tree is 121.8 cm. The scale with the length of the corner slope based on the length 1 of the flat slope and the scale with the length of the corner slope based on the length 1 of the horizon can be seen side by side, so you can see by comparing both scales (rounded ).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The ruler of the present invention will be described with reference to FIG. 1, in which the scale of the length of the corner slope based on the length 1 of the flat slope and the length of the corner slope based on the length 1 of the horizontal line are used. A cylinder 2 in which holes for viewing the scales are formed in a row is covered on a shaft 1 in which the scales are arranged in parallel and carved. Attach polygonal handles (octagon in the drawing) 3 to each end of the axis 1 with the name of the gradient written.

The handle is provided with marks 5a5b for distinguishing between the scale having the length of the corner slope based on the length 1 of the flat slope and the scale having the length of the corner slope based on the length 1 of the horizontal line.

A mark 7 indicating the base point is attached to the cylinder so that the base point of the scale marked on the axis of the ruler can be easily understood.

It is also possible to use a ruler in which a scale having a length of a corner slope based on the length 1 of a flat slope is engraved on a material such as a rod or a strip, and each slope is separated.

On a material such as a rod-shaped or strip-shaped material, a scale having a length of a corner slope based on a length 1 of a flat slope and a scale having a length of a corner slope based on a length 1 of a horizontal line are parallel to each other. It is also possible to use a ruler that is engraved side by side and separated for each gradient.

EFFECT OF THE INVENTION The ruler of the present invention calculates the length of the corner tree required for the length of the eaves, and the answer is used as a scale for engraving, so the necessary scale is written on the corner tree. You can know the length of the corner tree.

In the ruler of the present invention, the scale of the length of the corner slope based on the length 1 of the flat slope and the scale of the length of the corner slope based on the length 1 of the horizon can be seen side by side. By comparing both scales, the eaves of a flat slope can be replaced with the eaves of a horizon.

In the ruler of the present invention, since both scales can be seen side by side, the eaves of the length of the horizon can be replaced with the eaves of the length of the flat slope (taruki).

In the ruler of the present invention, the actual length of the corner tree can be known by measuring the length of the scale of the ruler with an insert.

The ruler of the present invention is a tile having a flat slope length such as the working size of a roof or a distributed slope, and the corner slope length required for this is based on the flat slope length 1. It can be represented in a corner tree using the scale of the length of the corner slope.

When installing the corner wood, the length from the girder to the inside, the pillar, etc. is represented by the length of the horizontal line in the construction design drawing, so the length 1 of the horizontal line of the ruler of the present invention was used as a reference. If you use the scale of the length of the corner slope to find the length of the corner tree,
The work to attach the corners is fast

The ruler of the present invention is easy to understand and can be easily used by beginners.
