Flame isolation apparatus for apartment balcony {Flame isolation apparatus for APT balcony}

The present invention relates to a flame barrier device for apartment balconies, and in detail, a structure of a fireproof cloth wound and installed on a balcony railing so as to block the flames encircled from a lower floor spreads upward from the floor of a balcony. It relates to a fire protection device for an apartment balcony having a device for blocking the.

Apartment apartments have balconies as safety spaces to prevent flames from entering the upstairs generation in case of fire, but the occupants lose their functions through the balcony expansion work. As a safety measure, the expansion of apartment balconies requires the establishment of fire evacuation spaces and fire protection facilities.

These fire-blocking facilities are equipped with automatic fire detectors on the balconies, and for apartments where sprinklers cannot reach the balconies, the installation of 90cm fireproof panels or fireproof glass including the floor thickness is required.

As shown in FIG. 1, the fireproof board and the fireproof glass 95 are exposed to dust and foreign substances due to being fixedly installed on the outdoor balcony railing 10. And cleaning to remove debris.

Fireproof glass is mainly installed on the balcony railing that is spaced within 30 cm from the double glazing 96, which is an indoor / outdoor boundary wall, and radiant heat emitted from the glazing fire blocking glass is also transmitted to the interior through the double glazing.

In addition, if the extended room is maintained at about 450 ℃, the presence of wood-fired furniture and polymer combustible interior material used as the finishing material of the expanded indoor space creates an environment vulnerable to radiant heat, and the fireproof glass extends the balcony. Spots within 30-40 cm of an interior space are more vulnerable to radiant heat.

Therefore, when the fire protection glass that primarily blocks the flames encircling from the lower floor blocks the flames for a long time, there is a problem of a fire transition due to radiant heat transmitted to the room through the double window.

The double glazing adjacent to the flame-retardant glass is vulnerable to radiant heat and flames encircling from the bottom, but protects the double glazing from the radiant heat emitted from the fire-resistant glass because it acts as a barrier to smoke and toxic gases. Device is required.

In the flame arrester which pulls up the fireproof fabric upwards,

When both ends of the upper bar combined with the refractory fabric is pulled upward, the upper bar causes a bending phenomenon in which the central portion sags due to its own weight.

This warpage phenomenon can be aggravated as the width of the apartment balconies increases, the center of the stretched inner Hwacheon sag, both ends of the tension is pulled tightly contains the fragility of both ends of the refractory fabric combined with the top bar.

In order to solve the above problems, the present invention is installed on the balcony balustrade of the apartment is a structure that spreads the fireproof fabric from the balcony floor upwards, which acts as a fire barrier plate when a fire occurs,

A lifting device which prevents slip phenomenon and sag of the upper bar combined with the upper end of the refractory fabric and starts up in conjunction with the roller pipe; Refractory fabric with a metal foil strip attached to the left and right ends of one side to prevent damage of the refractory fabric to act as a flame barrier plate; It is an object of the present invention to provide a flame barrier device for an apartment balcony having a radiation heat shield device.

The present invention is installed on the balcony railings to expand the fire-resistant spring rolled up in the enclosure upwards, and to roll it around the enclosure,

There is no deflection of the upper bar combined with the upper part of the refractory fabric, the lifting function that allows the rotational movement of the roller pipe and the vertical movement of the upper bar to interlock without the upper bar slipping downward, and the function of offsetting radiant heat into vaporization heat. To implement;
