Description

Hidden fire control smoke exhaust window structure

Technical Field

The utility model relates to a building design technical field especially relates to a hidden fire control smoke exhaust window structure.

Background

According to the new regulation of 'building design fire protection code', the fire-fighting evacuation stairway needs to be provided with a smoke exhaust window not less than 1 square meter at the upper part of the top layer of the stairway. In the design practice of public buildings in recent years, when the height of a common window is low and the common window cannot be used as a smoke exhaust window, an electric smoke exhaust window needs to be additionally arranged at a high position.

Such windows are typically ignored by designers during the design phase of a building scheme. And until the construction drawing design stage, the technical window holes are required to be additionally arranged, so that the outer vertical face is damaged. When the building is a solid curtain wall veneer, the opposite surface of the opening has larger influence.

The common fire-fighting smoke exhaust window is directly arranged on a civil wall and then is recessed by a hole formed in a curtain wall; another method is to directly open a smoke exhaust window on the curtain wall. However, when the curtain wall is specially shaped and is not suitable for windowing or cannot be windowed, windowing is more reluctant.

The specific meaning of the above terms in the utility model can be understood according to specific situations by those of ordinary skill in the art.

As shown in fig. 1, the utility model provides a hidden fire control smoke exhaust window structure, include: set up the exhaust window 1 on wall body 100, be equipped with on the curtain 200 of the 1 department that corresponds of exhaust window and arrange smoke zone 2, should arrange smoke zone 2 and make the inside and outside air intercommunication of curtain, exhaust window 1 with curtain fossil fragments cavity position between the exhaust zone 2 installs a confined smoke exhaust passage 3, 3 one end covers of smoke exhaust passage smoke exhaust window 1 to fix the exhaust window at the smoke exhaust passage tip with the angle sign indicating number, the other end covers arrange smoke zone 2, with curtain fossil fragments welding, that is to say, exhaust window 1 passes through smoke exhaust passage 3 intercommunication smoke exhaust zone 2, and then get rid of the curtain with the flue gas in the building outside, avoid its space internal diffusion between curtain and the building wall.

The further improvement is that the smoke exhaust window 1 is a middle-hung smoke exhaust window (as shown in figure 2) or a lower-hung smoke exhaust window (as shown in figure 3), so that the opening angle of the smoke exhaust window in the cavity of the keel of the curtain wall can reach at least 70 degrees, and the smoke exhaust window is not blocked when being opened.

The further improvement is that the smoke exhaust window 1 is an electric smoke exhaust window, which is convenient for controlling the opening states of all the smoke exhaust windows 1 on the building.

The area of the smoke exhaust area 2 is not smaller than that of the smoke exhaust window 1.

In a further improvement, the smoke exhaust area 2 is a through hole array (as shown in fig. 4) or a louver, and in the case of the through hole array, the strength of the curtain wall at the smoke exhaust area 2 after punching is weakened, and reinforcing ribs can be added on the back surface of the area to improve the strength and the flatness of the plate surface. When the louver is used, the insect-proof net is arranged behind the louver to prevent insects and birds from entering the louver.

The further improvement is that the smoke exhaust window 1 is provided with a wire mesh to prevent insects and birds from entering, and the wire mesh can adopt a diamond gauze mesh.

Application example

The aluminum plate model of the curtain wall of the outer vertical face designed by a certain public building project adopts the 'fish scale-shaped triangular splicing', the color is light gray, and the caulking glue between the aluminum plates is dark gray. Because the outer vertical surface aluminum plate curtain wall is triangular and can not be opened like a conventional rectangular smoke exhaust window in a blocking manner, and the smoke exhaust window directly arranged on the aluminum alloy curtain wall can influence the outer vertical surface effect, the smoke exhaust window design scheme in the technical scheme is adopted.

A smoke exhaust window with a regular shape is arranged on a civil engineering wall above a staircase. The smoke exhaust window adopts a downward suspension and is arranged by 4 small blocks, the height of a single window is about 600 degrees, the opening angle of the single window in the cavity of the keel of the curtain wall can reach 70 degrees, and the single window is not blocked when being electrically opened. The window opening area is: (2.2-0.2) x (1.2-0.2) x100% =2 square meters.

The aluminum plate on the outer side of the curtain wall is punched, and the outer aluminum plate is not limited in the hole arrangement pattern. In general, a 2.5-thick aluminum plate adopts round holes, the diameter of the round holes is less than 40mm, the round holes are closely arranged, and the punching rate can reach 60%. Because the strength of the punched aluminum plate is weakened, the reinforcing rib is additionally arranged at the rear part, and the flatness of the plate surface is improved. In addition, the insect-proof net is arranged at the back of the shutter, and the diamond gauze is arranged at the smoke exhaust window to prevent insects and birds from entering. Equivalent conversion of trompil area, 3.4 square meter perforated aluminum plate's trompil effective area: 3.4x60% >2 square meters, and meets the ventilation requirement of consistent inside and outside or small inside and large outside. Meanwhile, the outer vertical face keeps the continuity of the epidermis and no concave opening appears.

A closed cavity treatment is carried out between the smoke exhaust window and the smoke exhaust area, four sides are closed to form a smoke exhaust channel, the inner cavity is in a bell mouth shape, the outer side of the lower plate faces downwards, and rainwater is led out conveniently. The side panel is from inside to outside in proper order: 2.5mm fluorine carbon aluminium veneer dysmorphism board (finish coat, with curtain aluminum plate), 1.5mm SBS waterproofing membrane full lap round (waterproof layer), 1.5mm galvanized steel sheet seals round (outer wall surface course), fire prevention is glued sealedly, 100mm fire prevention rock wool (heat preservation), 40x40x4mm hot-galvanize steel pipe (structure basic unit), 1.5mm galvanized steel sheet bearing (outer wall surface course).

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
