TECHNICAL FIELD AND PROBLEMS TO BE SOLVED
The present invention relates to a base height adjusting tool that can easily finely adjust the height of a base in a wooden building.
[0002]
[Prior art]
Conventionally, in a wooden building, since the foundation is directly laid on the top end of the fabric foundation, the level (level) depends on the construction accuracy of the top end of the fabric foundation. For this reason, it is common to use pre-cut structural materials and feathers, and when the construction accuracy of the top end of the fabric foundation is low, the level error of the foundation remains as it is. The floors of the 1st and 2nd floors and the construction of the fittings were not good.
[0003]
As a technique for solving such a problem, a base adjusting plate described in Japanese Utility Model Laid-Open No. 6-20771 has been proposed. The base adjusting plate is mainly composed of a pair of wedge-shaped pieces having inclined surfaces inclined in opposite directions, and sawtooth surfaces that engage with each other are formed on the inclined surfaces. Then, this foundation adjustment plate is interposed between the foundation and the foundation, and the base height is adjusted by striking the bottom surface of one wedge-shaped piece with a hammer or the like and shifting the sawtooth of the sawtooth surface. It ’s like that.
[0004]
However, the foundation adjustment plate described in the above publication is provided so as to adjust the height of the foundation by hitting the bottom of the foundation adjustment plate from between the foundation and the foundation, which makes it difficult to work. . In addition, since the adjustment of the base height depends on the step of the sawtooth surface, there is a limit to the fine adjustment of the height.
[0005]
Accordingly, an object of the present invention is to provide a foundation height adjuster capable of easily finely adjusting the height of the foundation.
