Title:
EARTHQUAKE REINFORCEMENT/SEISMIC ISOLATION STRUCTURE CONSTRUCTION METHOD FOR TRADITIONAL WOODEN BUILDING
Document Type and Number:
Japanese Patent JP2023140242
Kind Code:
A
Abstract:
To provide an "earthquake reinforcement/seismic isolation structure construction method" for a traditional wooden building located on soft ground and with a stone foundation structure for column bases.SOLUTION: When replacing a building's soft ground with a pressure-resistant foundation that has structural strength, a foundation stone of a stone foundation structure are directly supported. A back side of a replaced pressure platen foundation is smooth, and it is expected that it will slide on soft ground in the event of a large-scale earthquake. As a countermeasure, the back side of the pressure platen foundation has a foundation waffle beam shape structure. Furthermore, support steel pipe piles are press-fitted into the ground from the pressure platen foundation to a support stratum directly below. Uneven settlement of the pressure platen foundation is prevented. A foundation complex is formed by the foundation waffle beam shape and foundation piles, a pile head securing tube is attached to the steel pipe pile, it functions as a seismic isolation device, and can be used in the event of a large-scale earthquake. The structural strength of a traditional wooden building, which has a friction effect due to the viscous characteristics of the soft ground layer in the foundation complex, is also ensured.SELECTED DRAWING: Figure 1
