Description

Technology Field

[0001] The present invention relates to a stainless steel emergency ladder installation structure, and more specifically, to a stainless steel emergency ladder installation structure that is made of stainless steel and is resistant to corrosion, and is installed on a wall to enable quick and safe evacuation between floors in the event of an emergency such as a fire. Background Technology

[0003] Due to recent rapid industrial development and population growth, many high-rise buildings have emerged in residential culture. These high-rise structures offer the advantages of accommodating a large number of people within a narrow site, allowing for views of the surrounding landscape from inside, and enabling the inclusion of various amenities within a single building.

[0004] In the event of an emergency such as a fire in such high-rise buildings, evacuation must be carried out via emergency stairwells; however, these stairwells become pathways for flames, making evacuation virtually impossible and potentially resulting in significant casualties. To address this, the law mandates that buildings exceeding a certain number of floors be equipped with emergency escape means for disaster evacuation.

[0005] To address these problems, there is a method of escaping from a fire by installing a rescue rope on the exterior wall of the veranda; however, such rescue ropes are extremely difficult and dangerous for the general public to use, and because the escape speed is slow, they are rarely used in practice.

[0006] Meanwhile, the aforementioned background technology is technical information that the inventor possessed for the derivation of the present invention or acquired during the process of deriving the present invention, and it cannot necessarily be considered publicly known technology disclosed to the general public prior to the filing of the present invention.

[0024] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

[0025] FIGS. 1 and FIGS. 2 are drawings illustrating the schematic configuration of a stainless steel emergency ladder installation structure according to one embodiment of the present invention.

[0026] Referring to FIGS. 1 and 2, a stainless steel emergency ladder installation structure (10) according to one embodiment of the present invention includes a fixed frame (100), a movable frame (200), two first side frames (300), two second side frames (400), a first floor frame (500), a second floor frame (600), a rotating shaft (800), two wires (900), a protective cover (1000), and a water spray module (1100).

[0027] The fixed frame (100) is made of stainless steel in the shape of a square frame that is fixed to a wall.

[0028] In one embodiment, the fixed frame (100) may be fixed to a wall surface by a bracket attached to its upper and lower surfaces or sides.

[0029] The movable frame (200) is made of stainless steel in the shape of a square frame installed in front of the fixed frame (100).

[0030] The two first side frames (300) are each made of stainless steel and have a square frame shape, with each rear end connected to both ends of the fixed frame (100) so as to be folded and unfolded, and a plurality of first crossbars (310) arranged vertically and spaced apart on the inside so as to be stepped on.

[0031] The two second side frames (400) are each made of stainless steel and have a square frame shape, with each front end connected to each end of the movable frame (200) so as to be folded and unfolded, and each rear end connected to each front end of the first side frame (300) so as to be folded and unfolded, and have a plurality of second crossbars (410) arranged vertically spaced apart on the inside so as to be stepped on.

[0032] Here, the first crossbar (310) and the second crossbar (410) are installed so that a user can step on them. Accordingly, in the event of an emergency such as a fire, the user can move to an upper or lower floor by stepping on the first crossbar (310) and the second crossbar (410) after unfolding the emergency ladder, thereby enabling quick and safe inter-floor evacuation.

[0033] The first bottom frame (500) is made of stainless steel, with its rear end connected to the bottom of the fixed frame (100) so as to be foldable and unfoldable.

[0034] The second bottom frame (600) is made of stainless steel, with its front end connected to the bottom of the movable frame (200) so as to be folded and unfolded, and its rear end connected to the front end of the first bottom frame (500) so as to be folded and unfolded.

[0035] In one embodiment, the first floor frame (500) and the second floor frame (600) are formed in the shape of a plate, wherein the first floor frame (500) comprises a first body (510) having a first opening (511) that is open at the top and bottom, and a first door (520) that opens and closes the first opening (511), and the second floor frame (600) comprises a second body (620) having a second opening (611) that is open at the top and bottom, and a second door (620) that opens and closes the second opening (611).
