Title:
ELASTIC-PLASTIC ELEMENT, SEISMIC TIE COMPRISING SAME, AND BOILER SUPPORT STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2018/230014
Kind Code:
A1
Abstract:
Provided are an elastic-plastic element that ensures fatigue strength to be able to withstand repeated vibrations and that can improve durability, a seismic tie comprising same, and a boiler support structure. An elastic-plastic element (3) used in an insertion type seismic tie (110) is provided with a rhomboid opening (30A) in the body (30) and has a pair of first shoulders (31) and a pair of second shoulders (32) that extend so as to expand outward as same nears one end face (3AE) and the other end face (3BE) from both side faces along the length direction of the body (30) or from both the front and back faces in the thickness direction. The separation distance from end point positions (310) of the expansions of the first shoulder (31) and the second shoulder (32) to the one end face (3AE) and the other end face (3BE) is set to be larger than the separation distance from a first vertex (301) and a second vertex (302) to the one end face (3AE) and the other end face (3BE).
