Description

[Detailed description of the device]

[0001]

[Application field to which the device belongs]

 The present invention is mainly concerned with a common dimensional scale for length measurement used in construction work.

[0002]

[Prior art]

 The length measuring scale is the most basic measuring tool in construction work, and there are various types such as metal difference and tape measure. On the other hand, Japanese traditional shakunuki method is still used for wooden construction by the conventional method, and the scale and scale used for this are usually graduated.

[0003]

[Problems to be solved by the device]

 In Japan, the dimensional unification of wooden construction has not been nationwide yet, and there are dimensional standards unique to each region, such as Kansai, Kyushu, Shikoku, Hokuriku, and Kanto.

This is because the length of one space varies depending on each region. For example, in the Kanto region, 6 shaku is 1 space, whereas in Kansai, 6 shaku is 3 spaces. ing. Therefore, the dimensions of various building materials, interior parts, fittings, etc. were naturally different in each region, and they were not interchangeable at all, which was a major factor in increasing the cost of the entire building.

Furthermore, since the basic dimensions differ from region to region, it is almost impossible for a building engineer to engage in construction work in other regions due to the complexity of dimensional conversion. It was a major factor that hindered human interaction. In particular, since traditional wooden construction is performed based on the unique solid geometry of Japan, which is called empirical and practical rules of construction, it is difficult to work due to differences in dimensions. The engineer was bigger, and it was a big problem to pass down the traditional building technology to the next generation. Also, in the event of a large-scale disaster such as a large earthquake, tsunami, or large fire, building materials stocked or stocked in various places cannot be used for restoration as they are due to differences in standards, or carpenters, craftsmen and other skilled construction workers in other regions There was also a serious problem that we could not mobilize the recovery work.

The present invention is intended to solve this problem related to conventional wooden construction, and it is possible to construct a building with a nationwide common dimension, and to use the conventional rectangular technique as it is, which is convenient. It is intended to provide a common dimensional scale for various length measurements.

[0007]

[Means for Solving the Problems]

 According to this invention, a length of 30 cm is referred to as a shaku, and 10 equal parts thereof are referred to as a single size, and the scales 2 and 3 equally divided by the scale and the size are displayed on the surface of the scale main body 1 to solve the above problems. To solve the problem.

[0008]

[Embodiment of device]

 FIG. 1 is a perspective view of an embodiment of a common dimension scale for length measurement according to the present invention. This embodiment is in the form of a tape measure (convex scale). The surface of the main body 1 is graduated into graduations 2 equally divided into 30 cm and graduations 3 further divided into 10 graduations. The scale and the scale 3 are referred to as "dimensions", and the indications indicating them are given. The main body 1 is a metal strip having elasticity.

FIG. 2 is a plan view of another embodiment, and this embodiment is in the form of a difference, and the surface of the main body 1 is divided into graduations 2 which are equally divided into 30 cm, and the graduation 2 is further divided into 10 equal parts. The scale 3 is engraved, the scale 2 is called the scale, the scale 3 is called the size, and the display showing them is engraved.

FIG. 3 is a plan view of still another embodiment, which is in the form of a straight line ruler, and like the first and second embodiments, the surface of the main body 1 is spaced by 30 cm at a time. A scale 2 called a scale and a scale 3 called a scale are displayed by dividing the scale 2 into 10 equal parts. The material of this straight line ruler is exactly the same as the existing ones such as metal, synthetic resin and bamboo.

The embodiments shown in FIGS. 1, 2, and 3 described above are merely examples of the present invention, and any scale for measuring length is not limited to the above-described embodiments. Is clear. In addition, 30 cm is referred to as one shaku, when 6 shaku is taken as a standard based on this shaku, it is almost the average value of the Kanto area, Kansai area, Kyushu area, and other regional dimensions. But you can use it without any discomfort.

[0012]

[Effect of device]

 The common dimension scale for length measurement according to the present invention has the structure as described above, and has the same usage as that of the length measurement scale that has been conventionally used, and is used for dimension indexing during construction work. However, the displayed scales and dimensions are almost average values of regional dimensions such as Kanto, Kansai, Kyushu, etc., so the dimensions specified in this scale should be used as a reference. For example, it is possible to build a building with uniform dimensions that are unified throughout the country. Therefore, various building materials, interior parts, fittings, etc. are compatible and can be used anywhere in the country as they are, and the construction engineer does not have to bother with the tedious conversion work of dimensions. You will be able to engage in construction work anywhere in the country.

As described above, when the common dimension scale for length measurement according to the present invention is used, conventional wooden constructions nationwide are constructed with unified dimensions, and standardization of design and various building standards are performed. It will be possible to unify buildings, mobilize building engineers nationwide, and standardize education and training, which will have a great effect on contributing to the revitalization of wooden construction by conventional construction methods. Also, in the event of a large-scale disaster such as a large earthquake, tsunami, or large fire, there is the inconvenience of being unable to use the building materials for restoration work sent from various locations due to differences in standards, and building skills of other local areas. It is possible to solve the problem of not being able to mobilize personnel, and it has an excellent effect in terms of so-called crisis management.
