Title:
FIREPROOF STRUCTURE FOR THROUGH-PENETRATION FIRESTOPPING OF BUILDING
Document Type and Number:
WIPO Patent Application WO/2021/020614
Kind Code:
A1
Abstract:
The present invention relates to a fireproof structure installed to prevent fire from spreading through building penetrations where penetrating members such as pipes pass through compartment walls of the building. The present invention has the following advantageous effects. That is, there is no need to construct a conventional heat-insulating material which is separately installed on compartment walls in an area exposed to fire, and thus material costs and labor costs can be reduced. Further, fireproof fillers can expand into the penetrating members at an appropriate temperature without leaving any spaces therein, and thus compartment wall penetrations can be effectively blocked. In addition, the conventional method is disadvantageous in that a fireproof filling structure needs to be constructed directly at the site, and thus many restrictions are placed on working conditions and there are large quality differences among construction workers depending on their proficiencies. Contrarily, the present invention allows all types of fireproof devices to be manufactured by specialized factories, and thus can increase quality consistency and can also solve the problems of construction delay and the like according to the conditions of the site.
