OS Sealing SS Type Semi-Structured Ceiling Substrate 'OJ Type/ND Type'
OS sealing
Semi-structured seismic ceiling substrate
The "OJ type/ND type" is a seismic ceiling construction method that aims to integrate the structural frame and ceiling by directly connecting structural materials with the same strength as the structural frame to the ceiling substrate, thereby achieving semi-structuralization. It prevents the amplification of vibrations on the ceiling surface, similar to a suspended ceiling, and allows for ceilings that do not fall under specific ceiling regulations. (Detailed settings will be discussed in meetings.) Additionally, by arranging the shape of the structural materials and limiting the fixed length of the ceiling, it can also accommodate sloped ceilings and other variations. 【Features】 ■ Aims for integration of the structural frame and ceiling ■ Prevents amplification of vibrations on the ceiling surface like a suspended ceiling ■ Allows for ceilings that do not fall under specific ceiling regulations ■ Can accommodate sloped ceilings by limiting the fixed length of the ceiling ■ Enables the construction of a consistently smooth ceiling using support materials *For more details, please refer to the linked examples of seismic ceiling construction or feel free to contact us.
