Pre-embedded/pre-built-in-hole creating apparatus and pipe bank box having the same

摘要

The present invention provides a pre-embedded/pre-built-in hole creating apparatus for buildings, including: a pipe casing for a pipe or a pipeline system of the building to pass there through; at least one thermal-expandable foam detachably accommodated within the pipe casing; an inspection annulus detachably joined with the pipe casing; and a slide cover installed onto the pipe casing and secured to the building structure. The at least one thermal-expandable foam in the hole creating apparatus embedded in the building structure can be removed via the detachable structure for inspection and replacement so as to maintain the flame-retardant function of the hole creating apparatus. Said apparatus further includes an annular shielding plate providing functions of airtight and smoke blocking for the through pipes as well as includes an identifying device providing information, tracking and service associated with the apparatus in order to guarantee long term safety.
