Abstract
Description
- The present invention relates to a fire/disaster evacuation facility for building, more specifically to the fire/disaster evacuation facility for building that is used as a balcony parapet to prevent falling in ordinary day without fire risk, and whose structure is converted into a fire and a disaster evacuation facility for residents isolated by the fire to be safely evacuated to the ground when the fire occurs.
- Commonly, the high-rise buildings are increasing in the present day in order to make effective use of a small site and to expand a living space of the building. A main entrance door for human access is usually prepared in the high-rise buildings, a veranda is installed in the opposite side of the main entrance door, and a safety parapet for preventing falling is installed on the veranda.
- Such high-rise buildings have an advantage of being able to accommodate a large number of people in the small site, and it is possible to look down the scenery in the high building, and have an advantage of having various convenience facilities inside.
- However, the high-rise buildings have a disadvantage of having a high frequency of fires due to the residence of many people inside the buildings soared on the small site, and have a problem that once a fire occurred, it could lead to a mass mortality event.
- Meanwhile, there is a way to avoid the fire by using a descending life line installed in the veranda to solve this problem. However, the descending life line has a problem that is difficult for the general public to operate it, and the other problem of the descending life line is that people cannot overcome their anxiety of using the descending life line in addition to their fear of fire because of the burden of putting the weight of the user on one rope.
- Meanwhile, as a prior art of this invention, "A safety balustrade for fire-escaping" of Korean patent registration number "10-0927317" has been filed and registered. The safety balustrade for fire-escaping may consist of: a first frame blocking the upper glass wall in ordinary day without fire risk, and being pivoted by a hinge fixed to the outer wall of the building and facing the lower glass wall or the lower outer wall in the event of fire; a second frame being placed between the first frame and the upper glass wall to block the upper glass wall in ordinary day without fire risk, and being pivoted to direction of the lower glass wall or the lower outer wall along the first frame in the event of fire; a stepping board, wherein its two ends of one side and two ends of the other side are connected to the first frame and the second frame respectively and it is erected abreast with the upper glass wall to prevent falling accident of upper floor residents in ordinary day without fire risk, and when the first frame and the second frame are pivoted to the direction of the lower glass wall and the lower outer wall, the stepping board is unfolded in the orthogonal direction between the first frame and the second frame in a state of being connected to the first frame and the second frame to provide a stepping space at the same time as widening the gap between the first frame and the second frame; and fixing means which fixes the one side of the second frame to the upper building structure for the first frame and the second frame not to be pivoted to the lower glass wall or the lower outer wall by the hinge in ordinary day without fire risk.
- An objective of the present invention is to solve such problems and is to provide the fire/disaster evacuation facility for building which allows people who are isolated in the high-rise building to descend safely to the ground through the veranda when the fire occurs in a high-rise building.
- In order to achieve the above objects, a fire/disaster evacuation facility for building of the present invention comprises a wall-fixed frame which is fixedly installed on an outer wall of a building facing against a balcony or veranda of the building as a square frame shape; an outer frame which is installed in front of the wall-fixed frame as a front closed square frame shape; a side folding ascending/descending means which comprises a pair of a first side wall and a second side wall which are installed in right and left sides of the wall-fixed frame and the outer frame, and are folded or unfolded with hinge-combination, wherein front upper and lower sides of the first side wall are axially fixed to the outer frame, and rear upper and lower sides of the second side wall are axially fixed to the wall-fixed frame; a lower folding foothold which comprises a first lower board and a second lower board which are installed under the wall-fixed frame and the outer frame, and are folded or unfolded with hinge-combined, wherein front upper and lower sides of the first lower board is axially fixed to the outer frame, rear upper and lower sides of the second lower board is axially fixed to the wall-fixed frame; an emergency exit which enables a man to move to a lower floor through the lower folding foothold when a fire or disaster occurs; a folding emergency exit opening and closing means which opens or closes the exit by opening or closing in an installed state to the emergency exit, and is folded according to the lower folding foothold (15) when the lower folding foothold is folded, and is unfolded according to the lower folding foothold when the lower folding foothold is unfolded; an upper evacuation structure converting means which provides an evacuation passageway by unfolding the side folding ascending/descending means folded (stacked) between the wall-fixed frame and the outer frame, the lower folding foothold, and emergency exit opening and closing means according to operating an upper handle, when the fire occurs, and, at the same time, by pushing the outer frame to a front of a high-rise building; and a lower evacuation structure converting means which provides an evacuation passageway by unfolding the side folding ascending/descending means folded (stacked) between the outer frame and the wall-fixed frame installed on the lower floor, the lower folding foothold, and the folding emergency exit opening and closing means according to operating a lower handle and, at the same time, by pushing the outer frame installed on the lower floor to the front of the building when the fire or disaster occurs; the side folding ascending/descending means and the lower folding foothold and the folding emergency exit opening and closing means are stacked between the wall-fixed frame and the outer frame and are used for a safety parapet for preventing falling in ordinary day without a risk of fire or disaster in a state that the wall-fixed frame and the outer frame face against each other, when the fire or disaster occurs, if the upper and lower handles are operated, the lower folding foothold and the folding emergency exit opening and closing means, and the side folding ascending/descending means which are structurally converted to the fire evacuation, and which are stacked by the upper and lower evacuation structure converting means, and which are installed on the current floor and the lower floor, are unfolded, at the same time, and the outer frame moves to the front of the building; wherein an evacuating person opens the folding emergency exit opening and closing means installed on the current floor and then shelters him/herself from the fire or disaster by moving in a direction of the emergency exit of the lower floor through the emergency exit.
- According to the present invention, the fire/disaster evacuation facility for building comprised of such structure is used as a safety parapet for preventing falling in ordinary day without fire risk, and its structure is converted to be used as an evacuation facility for fire evacuation to reduce damage for humans when the fire occurs.
