「For the timber portion, a two-way moment-resisting frame structure using large-section glued laminated timber has been adopted, and the validity of its structural performance is being verified through loading tests on full-scale specimens.」
For mid-rise timber buildings, the project has progressed to verifying structural performance through full-scale loading tests and completing a six-story hybrid-structure building. - FY2025AdvancedAnnual report
「Because design seismic forces are proportional to a building’s weight, reducing building weight makes it possible to slim down columns and beams and reduce the amount of reinforcement. 髙松建設㈱ is focusing on reducing floor slab weight and developing slabs with a composite structure of CLT (cross-laminated timber) and RC (reinforced concrete).」
For the CLT-RC composite floor slab, the details of the composite structure have been determined, and structural, fire-resistance and sound-insulation tests are being conducted toward third-party evaluation. - FY2024AdvancedAnnual report
「We are advancing the detailed design of the composite structure and conducting various performance tests, including structural, fire-resistance and sound-insulation tests.」
The laminated timber-concrete composite slab project has progressed to detailed design and structural, fire-resistance and sound-insulation performance testing. - FY2022First statedAnnual report
「Accordingly, focusing on reducing slab weight, we will develop slabs using a composite structure of laminated timber and concrete.」
To reduce building weight, column and beam sizes, and reinforcement quantities, the company will develop composite slabs made of laminated timber and concrete and conduct structural, fire-resistance and sound-insulation performance tests.
