Title:
ELASTIC WASHER AND JUNCTION STRUCTURE OF LUMBER
Document Type and Number:
Japanese Patent JP2017015220
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To raise construction efficiency by facilitating handling of an elastic washer.SOLUTION: A spring 10 having a bolt insertion part 13 is overlapped with a planar washer substrate 1 having a bolt hole 5 to be made into a state in which the bolt hole 5 is communicated with the bolt insertion part 13 (a)(b). In the state, both circumferential parts are covered with a film 20 in which an upper opening 21, a lower opening 22 are secured to be made into an elastic washer 30 (c)(d). The elastic washer 30 has structure without including a nut 57, and becomes a state in which the washer substrate 1 and the spring 10 maintain a relative position by the film 20. In a state of attaching the film 20, the elastic washer is attached to a surface 35 of a lumber 35, and used by passing a shaft of a bolt 33 through the upper opening 21, the bolt insertion part 13, the bolt hole 5, the lower opening 22, and tightening a nut 36 to the shaft of the bolt 33 (b).SELECTED DRAWING: Figure 1
