柱補強構造及び柱補強構造の構築方法
Document Type and Number:
Japanese Patent JP6920688
Kind Code:
B2
Abstract:
To achieve a column reinforcement structure which can be constructed with good workability and has high reinforcing strength and a construction method of the column reinforcement structure.SOLUTION: A column reinforcement structure 100 can be constructed with good workability by fastening a pair of reinforcement metal fittings 10 arranged so as to lean against a column P in a direction where abutting plate parts 12 are made to abut on the column P with fastening members 20. Since the column reinforcement structure 100 has a double structure by the abutting plate parts 12 abutting on a peripheral face of the column P and rectangular plate parts 11 installed in positions away from the column P, the structure has higher reinforcement strength. Especially, spaces R having polygonal shapes in a cross sectional view (pentagonal shape in cross sectional view) are formed between the abutting plate parts 12 and the rectangular plate parts 11 and therefore the double structure by the abutting plate parts 12 and the rectangular plate parts 11 becomes a stable three-dimensional structure. Thus, the column P can sufficiently be reinforced by the column reinforcement structure 100.SELECTED DRAWING: Figure 2
