DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stretch wall structure having a smoke exhaust opening.

[0002]

2. Description of the Related Art Zhang wall is widely used for renovation to cover the outer wall of a newly built building, for example, bare concrete body, or for retrofitting the obsolete or damaged building outer wall of an existing building. For example, 4-42
No. 513 proposes a stretch wall structure for retrofit.

According to the above-described upholstered wall structure, there are disadvantages such as generation of dust as compared with renovation in which an exterior tile or a decorative mortar of an existing building is peeled off and a new outer wall material is installed. The renovation of the existing building will be completed in a short period of time. In addition, it is easy to cover and decorate the exterior wall of the newly built building with bare concrete with upholstery.

[0004]

However, in the above-described upholstered wall structure, since the entire outer wall of the building frame is covered with the upholstered wall, additional consideration for disaster prevention is required. In other words, when a fire occurs on the indoor side, it is desirable to have a structure capable of efficiently discharging smoke to the outside.

The present invention has been made in view of such circumstances,
It is an object of the present invention to provide a building frame having a stretched wall capable of efficiently discharging smoke to the outside when a fire occurs on the indoor side.

[0006]

According to the present invention, means for solving the above-mentioned problems are constituted as follows. That is, the upholstery wall is extended with a predetermined space between the outer wall and the outer wall, and the lower side of the punching metal is provided between the outer wall and the upholstery wall.
Air into the space from the
An openable and closable smoke exhaust opening facing the flow passage is provided on an outer wall corresponding to a ceiling of a building frame in which an outside air circulation flow passage to be discharged is formed.

[0007]

[Function] In the event of a fire on the indoor side, smoke is efficiently discharged from the smoke exhaust opening opened in the ceiling and the corresponding outer wall of the building frame toward the space between the outer wall and the upholstery wall. be able to.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a stretch wall structure having a smoke discharge opening according to the present invention. 1 is a vertical sectional view of a main part of the upholstered wall structure, FIG. 2 is a plan view of the main part, FIG. 3 is a mounting structural view of a lid for opening and closing the smoke exhaust opening, and FIG. FIG. In these figures, reference numeral 1 denotes an existing (or new) building frame, 2 denotes its outer wall,
Numeral 3 denotes a wall extending between the outer wall 2 and the space 4 and a supporting member 5 for supporting the wall 3 on the outer wall 2. 6, a punching metal 7 is laid between the lower end of the upholstery wall 3 and the outer wall 2, and the outside air is introduced into the space 4 from below the punching metal 7 so that the old cap portion 21 And Kasagi 6
An outside air circulation passage is formed between the upholstery wall 3 and the outer wall 2 so as to be naturally discharged to the outside from the aluminum gallery 8 erected between the outer wall 2 and the inner rim.

[0009] A smoke exhaust opening 9 having an openable / closable lid 10 is opened on the outer wall 2 of the upholstered structure constructed as described above, and when a fire occurs on the room 11 side of the building frame 1, the ceiling is opened. The smoke detection sensor 13 attached to the section 12 detects this, opens the lid 10, and discharges the smoke into the space 4. In the space 4, as described above, smoke is efficiently discharged from the aluminum gallery 8 to the outside by natural convection, and the room 11 is released from the damage caused by filling the room with smoke, and is quickly evacuated without confusion. And safety is ensured.

The above-mentioned smoke exhaust opening 9 is provided on the ceiling 12 of each floor.
(See FIG. 4), and each of the lids 10,... Locks by operating a solenoid of a lock device 14 according to a detection signal from a smoke detection sensor 13 on each floor. By releasing, the lid 10 normally closed by the spring cylinder 15 is opened outward (see FIG. 3).

The above-mentioned lid 10 is preferably divided into a plurality of pieces so that the opening operation in an emergency can be performed smoothly (see FIG. 2). However, when the room 11 is relatively narrow, a single piece is used. There may be. In addition, the smoke exhaust opening 9 forms a partition section 16 adjacent to the outer wall 2 in a part of the ceiling section 12 and is viewed from the indoor 11 side by a tape-shaped or net-shaped ceiling lid 17 stretched under the section. It is concealed not to be.

The present invention does not specify the lid 10 that covers the smoke exhaust opening 9 so as to be openable and closable, and the lid may be a manually openable / closable type.

The upholstery wall 3 is formed by surrounding the outer periphery of a rectangular metal thin plate with a metal reinforcing frame, and may be provided with a light-transmissive window made of, for example, a synthetic resin plate or a glass plate at an appropriate place. ,
In addition, the support member 5 that supports the upholstery wall 3, for example, moves the first fastener into and out of the support bone attached by welding, bolting, or the like at predetermined intervals in the vertical and horizontal directions of the outer wall 2 of the building frame 1. The second fastener is fixed to the first fastener with bolts so that the position can be adjusted vertically with respect to the first fastener, and the vertical fastener is fixed to the second fastener with bolts. While fixing
It is preferable that a blind in the left-right direction is provided between the respective cubicles, and the upholstery wall 3 is fitted and fixed in a lattice-like space formed by the cubic and the blind. The present invention can be applied as long as the upholstery wall 3 is extended so as to form a space 4 at a predetermined interval between the outer wall 2 of the building frame 1 and the outer wall 2 of the building frame 1 without specifying the present invention. Nor. Further, it is preferable that the space 4 is divided into right and left to form a chimney, and the efficiency of convection is further increased by the chimney effect.

[0014]

As described above, according to the upholstery wall structure having the smoke exhaust opening of the present invention , the pan between the outer wall and the upholstery wall is provided.
Introducing outside air into the space from below the metal
An outside air circulation channel is formed to allow natural discharge from the gallery to the outside.
An openable and closable smoke exhaust opening facing the flow passage was opened on the outer wall corresponding to the ceiling of the building frame , so that if a fire occurred on the indoor side, the smoke exhaust opening would allow the outer wall to be stretched. The smoke can be efficiently exhausted toward the space between the wall and the safety at the time of evacuation is secured.
