Title:
FRAMEWORK REINFORCEMENT STRUCTURE
Document Type and Number:
Japanese Patent JP2023137449
Kind Code:
A
Abstract:
To improve toughness of a framework structure so that various wooden buildings including traditional wooden buildings can maintain sufficient earthquake resistance and enable aseismatic repair to be securely and easily executed even if error occurs in positions of adjacent frameworks.SOLUTION: A connection part 4 for connecting both ends of an existing column material 2 and a reinforcement frame bar 3 that are adjacent to each other has a main body fitting 40, a rod-like first coupling member 41, and a rod-like second coupling member 42. The main body fitting 40 has an error absorption part to absorb error at positions in horizontal direction between the existing column material 2 and the reinforcement frame bar 3 that are adjacent to each other. A moment resistance joint, which resists an external force when the column material 2 is subjected to the external force, is applied to a junction of the first coupling member 41 to the column material 2. A moment resistance joint, which resists an external force when the reinforcement frame bar 3 is subjected to the external force, is applied to a junction of the second coupling member 42 to the reinforcement frame bar 3.SELECTED DRAWING: Figure 3
