Title:
VIBRATION CONTROL NAIL AND VIBRATION CONTROL STRUCTURE USING THE SAME
Document Type and Number:
Japanese Patent JP2015224438
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration control nail that enhances vibration control performance of a wooden structure, along with vibration control structure using the same.SOLUTION: A nail is hammered into and penetrates a lumber on the front side and reaches a lumber on the rear side for fastening the two lumbers, and includes an upper nail part 14 located on the lumber on the front side, a lower nail part 18 located on the lumber on the rear side, and a central nail part 16 located between the upper nail part 14 and the lower nail part 18 and having a cross-section area smaller than that of the upper nail part 14 and the lower nail part 18. The central nail part 16 is repeatedly deformed by repeated vibration loads exerted on the lumbers on the front side and the rear side, thus absorbing vibration energy. The nail is formed overall by a plate-form metallic member 8, with a top edge bent perpendicularly to form a head part 10, while the central nail part 16 has a reduced cross-section area by being made narrower or having a window 20 opened. Also, irregularities 22 are formed in the width direction on the upper nail part 14 or the lower nail part 18, for increasing friction between the nail and a lumber material.
