[Construction Example] Expanding the existing eaves to create an indoor space that is protected from rain.
Non-stop construction method for factory operations" by First Plus Co., Ltd. "Big Roof Method
The "Big Roof Construction Method" is a technique for safely extending roofs, such as eaves that protrude from buildings. In this case, the customer wished to extend an existing 10-meter eave by an additional 7 meters while also enclosing the entire loading area indoors to allow work to be conducted without getting wet from the rain. Therefore, we developed a structural plan that incorporated the "Cover Build Method," constructing a new frame that covers both the extension area and the existing loading eave area. This allowed us to expand the loading area while maintaining operations during construction and enclosing it indoors. Considering truck access, we adopted aluminum over-slider shutters for the opening doors. The existing eave was integrated into the new roof, resulting in a spacious indoor loading area with sufficient strength. 【Construction Targets】 ■ There is ample space in front of the building. ■ The existing building has passed the completion inspection. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Yoshizawa Architectural Structural Design Co., Ltd. is a comprehensive design office that consistently handles everything from planning and design to construction and after-service for factory rebuilding and renewal in-house. There are various reasons for wanting to renew an aging factory or introduce new equipment, but the current situation is fraught with challenges, such as the inability to stop production, the costs associated with relocating to a temporary factory, and the resulting decrease in productivity. Our company employs methods like "Cover Build," which involves constructing a steel frame over the existing factory while keeping production equipment in place, and "Separate," which divides the construction period into phases (e.g., Phase 1 and Phase 2) to avoid a decline in operational rates during rebuilding. Additionally, to assess the potential damage buildings may incur during an earthquake, we conduct various seismic surveys, including crack investigations, concrete strength assessments, and rebar layout measurements. Based on the survey results, we propose seismic reinforcement plans. We focus on preserving the assets of companies, including buildings, machinery, materials, and products. Furthermore, we ensure the prompt recovery and continuity of operations. Supporting everything from seismic diagnosis to reinforcement comprehensively is what we, "Yoshizawa," are dedicated to.
