Description

Flames anti-spreading apparatus for fire of apartment house between floors}

The present invention relates to a flame arrestor, and more particularly, to an interlayer flamebreaker of a multi-family house for preventing fire from spreading to an upper floor when a fire occurs in a lower floor by installing on an outer wall of a balcony of a multi-family house.

As the balcony expansion became legalized from December 2005 (Article 2 (1) 15 and 46 (4) 4 of the Building Act Enforcement Decree (enforced on Dec. 2, 2005), the balconies of apartment houses were used for space use. Increasingly, apartments that expand the area of living rooms and rooms are increasing.

In this case, when the balcony is extended to utilize the space, the balcony's outer wall is made up of the living room and the room's direct wall structure. Therefore, when a fire breaks out in the lower floor, the fire spreads directly along the outer wall of the balcony to the upper floor. Section 4 requires mandatory installation of fireproof panels or fireproof glass windows at least 90 cm in height, including the thickness of the floorboard, at the ends of the balconies when the balcony is not included in the sprinkler's sprinkling range on the second or higher floors of the apartment.

However, when a large-scale fire such as a gas explosion occurs, the flames generated in the lower floor rapidly spread to the upper floor by using the fireproof board installed outside the balcony, so it is difficult to effectively block the flame spreading to the upper floor by the conventional fireproof board. There was.

In order to solve this problem, Patent No. 744719 and Patent No. 791806 disclose a technique for installing a fireproof plate outside the balcony. Such a conventional fireproof plate is fixed by soldering on the upper side of the fireproof board so as to maintain the folded state of the fireproof board. When the solder is melted by the flame in the event of a fire, the fireproof plate is detached as the fireproof plate is separated. Unfolded downward by a spring supporting the top.

However, such a conventional fireproof plate has to be exposed to the flame for a predetermined time the solder located above the fireproof plate in order to operate in a fire. However, if the flame moves to the upper layer at a high speed due to a momentary gas explosion in the lower layer or if a gust occurs around the fire during a fire, the flame moves to the upper layer at a high speed, before the solder melts. There was a problem that could spread to the upper floors.

Moreover, since the catching cover is easily fixed by soldering, it is easily detached when an external impact is applied, so that a fireproof plate is normally operated.

In order to solve the above problems, the present invention is to provide a fire protection device between the floors of a multi-family housing that can be firmly fixed to the fireproof panel unit in normal times, and can be quickly operated in the event of a fire.

It provides an inter-floor flame cutout device of a multi-family house, which is located at the bottom of the outer wall of the balcony closest to the lower floor so as to quickly detect the fire.

The locking unit, the housing; A safety pin elastically snapped to the housing; And a support bracket for supporting the lower side of the fireproof board unit by the safety pin so as to keep the fireproof board unit in a housed state.

The housing may include a locking protrusion snapped to the safety pin, and the safety pin or the locking protrusion may be dissolved in a flame at 70 ° C. to 100 ° C. to release the locking state of the support bracket.

Preferably, the support bracket has a flame inlet groove formed around a through hole through which the safety pin penetrates into the housing.

The fireproof panel unit may include a plurality of fireproof panels foldably connected to each other, in which case the frame is pivoted in accordance with the expansion of the fireproof panel unit and disposed horizontally on the balcony outer wall, along the fireproof panel unit. Can additionally block rising flames.

In addition, the fireproof board unit may include a plurality of fireproof boards installed to overlap each other so as to slidably extend in a linear direction.
