Height-raising method - メーカー・企業と業務用製品 | イプロスものづくり

[Construction Example] Raised the building by 6 meters to expand the lifting height of the crane inside the factory.

Construction method that does not stop factory operations" Electric Industry Co., Ltd. Kawagoe Factory "Lift-Up Method

The "Lift-Up Method" is a construction technique that raises a building while maintaining its seismic strength without dismantling the existing factory structure. In this project, we received a request to increase the crane lifting height due to the aging of the existing traveling crane. First, we conducted an investigation of the seismic resistance and strength of the existing building to confirm its current seismic resistance and strength. We determined that with reinforcement, it could withstand the elevation. During construction, we connected the columns of the raised portion to the existing column heads to enhance strength, and then, using the cover build method, we installed a new roof and walls before dismantling the existing roof from the inside. As a result, the crane lifting height was increased, contributing to improved work efficiency. 【Construction Targets】 ■ There are documents such as drawings and structural calculation sheets. ■ The foundation of the existing building has sufficient strength. *For more details, please refer to the PDF materials or feel free to contact us.
