■Ensuring the Continuity of Fireproof Coating The fireproof performance of our conventional products (made of aluminum) is approximately 28 minutes (based on our test values), so it is conceivable that continuity of fireproof coating cannot be ensured in quasi-fireproof structures or reinforced ceilings. By using a fireproof ceiling inspection opening, continuity of fireproof coating can be secured. ■Simplification of Construction To ensure the continuity of fireproof coating, there are cases where various methods are employed, such as installing a site-fabricated box-shaped fireproof coating above the ceiling inspection opening, but these measures can burden the site. This product eliminates the need for a box-shaped fireproof coating, leading to a reduction in on-site construction effort. ■Slimming Down the Visible Width for Aesthetic Appeal Compared to products compatible with 45-minute quasi-fireproof structures, the visible width has been made narrower, and the base material has been painted for a cleaner appearance. ■Consideration for Safety During Opening, Closing, and Inspections Since the ceiling materials for 60-minute quasi-fireproof structures or reinforced ceilings are heavier, a fall prevention chain is standardly equipped to prevent the lid from opening forcefully during inspections. ■Special Column Now Available by Mr. Noboru Yasui, Representative of Sakura Design Group, First-Class Architect Office "What are the important points regarding fireproof coating required for quasi-fireproof and fireproof buildings?" ↓Click the related link↓

In conventional residential foundation reinforcement methods, long curing periods were often required due to construction circumstances and the need to secure working space, making it difficult to carry out work while living in the home. The "FRP Grid Foundation Reinforcement Method" achieves both construction in narrow spaces and while living in the home. The method involves "chipping away the decorative mortar of the existing foundation" → "fixing an FRP lattice to the existing concrete with anchor pins" → "applying a specialized mortar at a minimum thickness of 15mm," making it possible to work even on small sites without the need to relocate outdoor units, piping, gutters, etc., or remove flooring materials. Additionally, it is possible to complete the work in an unprecedented short time of as little as 3 days. 【Necessary Qualifications for Design and Construction】 ■ Designers - First-class/Second-class/Wooden Architect - Participants of the seminar "Seismic Diagnosis and Reinforcement Methods for Wooden Houses" (organized by the Japan Architectural Disaster Prevention Association, etc.) - Participants of technical seminars organized by our company ■ Contractors and Construction Managers - Participants of technical seminars organized by our company *The technical seminars organized by our company are conducted in a format where the responsible person visits directly.
