Description

Technical Field

[0001] The present invention relates to an emergency entrance provided on the outer wall of a steel-framed building in a narrow area (an entrance for firefighters to carry out rescue activities in an emergency).

Background Art

[0002] Regarding buildings such as buildings, in the event of a fire or other emergency, it is obligatory under the Building Standards Act to provide an emergency entrance so that firefighters, emergency teams, etc. can enter from outside the building for fire extinguishing activities and rescue activities. [[ID=1,3]] Under the Building Standards Act, on the floors above the third floor in the part of the building with a height of 31 m or less, it is obligatory to install an emergency entrance in the event of a fire or the like. When this emergency entrance is also used as a lighting or ventilation window, glass into which a circle with a diameter of 1 m or more can be inscribed must be used for the lighting or ventilation window, or the size when the window is opened must be 75 cm or more in width and 120 cm or more in height, and it must be provided 80 cm or less from the floor surface.

[0003] Generally, the following three methods are adopted as the emergency entrance. (1) Type in which the window opens to the outside. (2) Type in which the window opens to the inside. (3) Type in which the window rotates.

[0004] In the case of the above (1) type in which the window opens to the outside, since it is easy to finish the rain between the window and the frame, it is easy to ensure water tightness. However, when opening the window, since the window protrudes greatly to the outside from the outer wall surface of the building, in order not to cross the window tip to the road as defined in the Building Standards Act, an open space is required from the outer surface of the building to the road boundary. Therefore, when building a building in a narrow area, an open space may be required outside the outer wall of the building from the viewpoint of effective use of land.

[0005] [[ID=,33]] In the case of the above (2) type in which the window opens to the inside, it can be installed without considering the legal dimensions up to the road boundary, but there may be a difficulty in water tightness.

[0006] In the type where the window in (3) rotates, since the upper and lower halves of the window protrude into the room, in terms of water tightness, it has both the advantages and disadvantages of the type that opens to the outside in (1) and the type that opens to the inside in (2). Also, since it is necessary to project the upper and lower halves of the window significantly from the outer wall surface, a legal dimension up to the road boundary is required.

[0007] Thus, in the three methods of (1), (2), and (3) above, each has its advantages and disadvantages. Currently, however, when a fire breaks out, it is necessary to fully open the window so that the air cylinder carried by the firefighter is not caught on the broken window glass or the like. Therefore, the type in which the window opens to the outside is widely used.

2. The upper crossbar of the single-leaf fire door combines an upper arcuate glass fixing member formed by bending the flat steel plate generally in a bow shape and an L-shaped upper crossbar member formed in an up-and-down inverted L shape. A gap for inserting the upper rail part formed in the upper guide rail member is provided between the rail clamping part formed in the L-shaped upper crossbar member and the rail clamping part formed in the upper arcuate glass fixing member, and they are fixed. Further, the lower part of the upper arcuate glass fixing member is bent generally in a Z shape to form a glass vertical fixing part for sandwiching the wire mesh glass between the upper crossbar cover part of the L-shaped upper crossbar member. The special emergency exit sliding door for fire protection equipment according to Claim 1, characterized in that it is configured as such.

3. The lower crossbar of the single-leaf fire door attaches a door wheel to the door wheel fixing part of the lower arcuate glass fixing member formed by bending the flat steel plate generally in a bow shape. A gap for inserting the lower rail part of the sliding door rail member is provided between the rail clamping part formed in the L-shaped lower crossbar member and the rail clamping part formed in the lower arcuate glass fixing member, and they are fixed. Further, the upper part of the lower arcuate glass fixing member is bent generally in a Z shape to form a glass vertical fixing part for sandwiching the wire mesh glass between the lower crossbar cover part of the L-shaped lower crossbar member. The special emergency exit sliding door for fire protection equipment according to Claim 1, characterized in that it is configured as such.
