Problems solved by technology

Through simple experiments, it is known that the water sealing effect is not ideal. To achieve a real water seal with the rubber strip and the aluminum alloy profile, the following conditions must be met at the same time: 1. The rubber strip must have appropriate hardness; 2. .There is a certain positive pressure on the contact surface between the rubber strip and the aluminum alloy; 3. The contact surface between the rubber strip and the aluminum alloy has a suitable matching precision; 4. The surface of the rubber strip and the aluminum alloy profile has a certain degree of smoothness. Process limitations, the above conditions are difficult to achieve

Embodiment 1

[0018] In Embodiment 1, no water is injected into the water guiding cavity 8, and the pressure inside the water guiding cavity is equal to the outside pressure at this time, and the water guiding cavity 8 can be regarded as an isobaric cavity.

Embodiment 2

[0019] Embodiment 2, change the water-stop sponge 4 in the groove 5 into a sealant 11, the side and bottom surface of the water-guiding cavity meet the water-tight requirements, slowly pour water into the upper mouth of the water-guiding cavity 8, when When the height of the experimental water 9 reaches H, the water pressure in the water guiding cavity P=HD (D is the specific gravity of the experimental water 9), at this time, the pressure in the water guiding cavity is greater than the pressure outside, and the pressure is not equal to the outside, and the leading The water cavity 8 becomes a cavity with hydraulic pressure.

Embodiment 3

[0020] Embodiment 3, drill a drainage hole on the sealing plate 10 for the experiment, drain the experimental water 9 in the water guiding cavity 8, and slowly pour water in the upper mouth of the water guiding cavity 8, and the water will flow from the experiment Use the drainage holes on the sealing plate 10 to flow out. When the water intake ≤ discharge volume, no water will accumulate in the water guide cavity 8. At this time, the water guide cavity 8 is still an equal pressure cavity. When the water intake > discharge volume, the water guide Water will slowly accumulate in the cavity 8 to form a water pressure P. At this time, the pressure in the water-guiding cavity is greater than the outside pressure, which is not equal to the outdoor pressure, and the water-guiding cavity 8 becomes a cavity with hydraulic pressure.

Abstract

The invention relates to a unit curtain wall structure capable of improving water tightness, which is characterized in that: an aluminum alloy protruded flange is arranged on an aluminum alloy right stile ; an elongated through waterproof rubber strip is embedded in the side face of the end part; the waterproof rubber strip is embedded into a groove on an aluminum alloy left stile; the through waterproof rubber strip is tightly matched with the side wall of the groove so as to form a watertight sealing strip; the rubber strip and the aluminum alloy left stile and the aluminum alloy right stile enclose to form a rear cavity of a longitudinal water guide cavity; a side frame on a curtain wall panel and the aluminum alloy protruded flange and the watertight sealing strip form a front cavity of the longitudinal water guide cavity; the aluminum alloy protruded flange is arranged on an aluminum alloy upper transverse beam; and an elongated through waterproof rubber strip is embedded in the side face of the end part and is tightly adhered to a side wall on an aluminum alloy lower transverse beam so as to form a transverse draining cavity with a watertight decorative cover. The unit curtain wall has clear paths of retaining water, guiding water and draining water, and the water tightness of the watertight sealing strip can be reasonably utilized.

Description

technical field [0001] The invention relates to a unitized curtain wall structure capable of improving watertightness. By improving the structural cooperation between the left and right vertical columns and the upper and lower beams of two unitized curtain wall panels, the rainwater leakage prevention performance of the unitized curtain wall is improved. It belongs to the technical field of curtain wall manufacture and installation. Background technique [0002] Unitized curtain wall is a production process in which all curtain wall components are manufactured and processed in the factory, and finally assembled into panels, and the panels are installed on the construction site. It is a high degree of factory production. The production and processing are carried out indoors, and the quality is easy to control. , The construction and installation process is safe and simple production process. In the prior art, unitized curtain wall panels are generally composed of aluminum a...
