Description

Component type constant pressure cavity water-proof and drainage structure of curtain wall

Technical Field

The utility model relates to the field of water prevention and drainage of glass curtain walls, in particular to an isobaric cavity water prevention and drainage structure constructed on a component type curtain wall system.

Background

The building curtain wall is an outer wall enclosure of a modern building, is hung on the outer side of a main structure of the building like a curtain, is coated on the surface of the main structure, and has the characteristics of light weight, dexterity and the like. The curtain wall is just like the coat of a building, not only protects the building structure and realizes the requirement of building waterproof heat insulation performance, but also is an important expression corresponding to the building art. The existing glass curtain wall is divided into a component type curtain wall and a unit type curtain wall. The component curtain wall is formed by installing upright column cross beams, panels, adhesive tapes and the like on a construction site, and the waterproof principle of the component curtain wall is that a complete waterproof line is formed on an outer surface skin to block water outdoors. The unitized curtain wall is assembled by upright column beams, panels, adhesive tapes and the like in factories, and the whole unitized curtain wall is transported to the site, and only needs to be hung on the site, and the waterproof principle of the unitized curtain wall is to construct an isobaric cavity by adopting the rain curtain principle.

The prior component type curtain wall is sealed and waterproof by gluing between glass and a column cross beam, and if a leak exists, the hidden danger of water leakage can exist under the condition of large indoor and outdoor pressure difference of large wind force.

Disclosure of Invention

(one) solving the technical problems

Aiming at the waterproof defect of the component type curtain wall, the utility model provides a novel waterproof structure, which can enable the waterproof capability of the component type curtain wall to be more effective.

(II) technical scheme

The utility model provides the following technical scheme that a cavity is constructed between a curtain wall upright post beam and glass, a sponge water stop block is arranged at the joint of an upright post and the beam of the cavity, and the sponge water stop block and the upright post beam are sealed by glue, so that a complete cavity is formed between the upright post beam and the glass. The aluminum alloy pressing plate and the adhesive tape are arranged outside the upright post beam, and are waterproof, three to four small holes are drilled on the bottom of the cavity, namely, the beam position, and are used for being communicated with outdoor air, when the outdoor wind is high in pressure, the air enters the cavity through the small holes, so that the air pressure in the cavity is consistent with the outdoor air pressure, rainwater is ensured not to be pressed into the room through small gaps because of the large indoor and outdoor pressure difference, and when a small amount of water enters the cavity through the adhesive tape between the aluminum alloy pressing plate and glass, the water can be discharged through the small holes, so that a complete waterproof and drainage system is formed.

Further, the glass and the aluminum alloy pressing plate are provided with adhesive tape water blocking.

Furthermore, a small amount of water enters the cavity between the glass and the curtain wall upright post cross beam through the adhesive tape.

Further, small holes are arranged on the aluminum alloy pressing plate to enable the cavity to be communicated with outdoor atmosphere.

Further, a small amount of water enters the cavity and falls into the bottom cross beam and is discharged outdoors through the small holes.

(III) beneficial effects

Compared with the prior art. The utility model provides a waterproof and drainage structure of a component type curtain wall, which has the following beneficial effects.

An isobaric cavity communicated with the outside is formed between the glass and the upright post cross beam, and after rainwater enters the cavity through the rubber strips of the glass and the pressing plate, the rainwater enters the bottom transverse cavity along the vertical cavity and flows to the outside through the small holes on the bottom transverse aluminum alloy pressing plate. The waterproof effect of the component type curtain wall can be improved.
