Fireproof structure for through-penetration firestopping of building

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 ofthe 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 compartmentwalls 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.

Description

technical field [0001] The present invention relates to a fire-resistant structure for preventing fire from spreading in a penetration portion where a penetration member such as a pipe penetrates a partition wall of a building. Background technique [0002] As a measure to prevent smoke or flames from rapidly spreading to adjacent rooms in the event of a fire in a building to minimize damage, a fire-resistant filling structure is a fire-resistant measure at the bottom or partition walls of a building where pipes or wires, etc. run through When set in such a penetration. [0003] That is, construction for sealing the penetration portion in conformity with the performance of the fire-resistant structure is performed, and this construction is called fire-resistant filling construction. [0004] figure 1 It shows that the sleeve is installed in general plastic pipes and electric wires, etc., which include materials with thermally fragile characteristics or constitute integral ...

Problems solved by technology

Therefore, there is a problem that the material cost and labor cost increase due to the additional construction of the heat insulating material 12

[0006] In addition, in the case where the two spaces divided based on the partition wall 11 are fire prevention measures that may cause a fire, it may happen that the construction of the heat insulating material 12 needs to be carried out on both sides of the partition wall 11, so the economic aspect The disadvantages of the above will be more obvious

[0007] In addition, in the existing method, it is necessary to directly execute the construction of the refractory filling structure on site, so various restrictions are imposed on the working conditions, and there are also significant quality variations due to the proficiency of the construction personnel. Disadvantages of waiting
