Developing doors that open even during large-scale earthquakes! Fire doors that ensure a reliable evacuation route.
"Ascord" is a high seismic, large deformation-following, automatically closing fire door that ensures fire resistance and reliable evacuation routes even immediately after a disaster. In the event of a fire occurring right after a major earthquake, even if the frame of the fire door deforms due to the building's distortion, the door will close without interfering with the upper frame or the floor. As long as the inter-story deformation angle of the building is within 1/90 (momentary maximum of 1/60), the door will close, demonstrating its function as a fire door (specific fire protection equipment) even during a major earthquake. 【Features】 ■ Door interference prevention (hinge axis extension) ■ Increased clearance at the top of the door ■ Electromagnetic release with "vertical displacement absorption mechanism" ■ "Displacement absorption mechanism" at the bottom of the door *For more details, please refer to the PDF document or feel free to contact us.
