Utilizing the know-how of installation method of ceiling system,DAIKEN has achieved both earthquake resistance and workability improvement.
After the Great East Japan Earthquake, the Japanese Building Standard Law was revised to require higher seismic performance for ceilings. However, there was a concern that fulfilling the demand with the conventional construction method would result in an increase in the construction workload.
To address this issue, DAIKEN adopted a unique new ceiling construction method that can improve the seismic performance of ceilings in a short construction period with less workload.
This solution uses a ceiling underlayment material that combines the benefits of conventional ceilings with those of system ceilings.
3 to 4 times the conventional construction workload is needed.
Construction workload is reduced by approx.
20 to 30%, compared to when using conventional ceiling method to improve the seismic performance.
Our new method showed a high seismic performance of 4,000 N with respect to the allowable ceiling proof stress in the "unit test" (static pressurization test) designated by the Ministry of Construction (the current Ministry of Land, Infrastructure, Transport and Tourism. (*In-house test result)
It is proved in our laboratory test that our rock wool decorative acoustic boards have a low risk to human life in the event of falls.
The new method contributes to the reduction of construction workload because the number of seismic braces is reduced.
