Description

Curtain wall deformation joint structure

technical field

The invention discloses a deformation joint structure of a curtain wall, which belongs to the technical field of fixing buildings.

Background technique

Deformation joints are an important part of large buildings, not only to meet the deformation requirements between buildings, but also to have a good decorative effect. The curtain wall design at the position of the deformation joint must not only meet the wind pressure resistance and plane deformation performance of the curtain wall, but also ensure the effectiveness of the air tightness and water tightness of the curtain wall when the building is displaced. The design of the curtain wall at the position of the deformation joint of the building should follow the principle that a panel of the curtain wall does not cross the deformation joint and the curtain wall keel is disconnected at the position of the deformation joint. The panel moves with the displacement of the building body on the side it is on.

The structural design of the deformation joint position should be able to adapt to the displacement of the main body of the building, so as to avoid the displacement of the curtain wall system from damaging. Deformation joints are generally located at the junction of adjacent buildings. Generally, there are main structural columns and shear walls on the indoor side. The curtain walls on both sides of the deformation joints should be waterproofed separately from the main structure, and flexible secondary waterproofing should be installed on the inside. , so that the displacement of the building will not damage the waterproof system and ensure the overall airtightness and watertightness of the curtain wall.

Existing curtain wall deformation joint designs include:

(1) The organ rubber strips are installed on the inside and outside of the deformation joint. Since the organ rubber strip is flexible, it can be stretched and compressed arbitrarily with the displacement of the building. This structure has the best displacement adaptability. The disadvantage is that the exposed organ rubber strip affects the Visual effect, the exposed organ rubber strips are easy to age and affect the waterproof performance and air tightness of the curtain wall;

(2) The inner side of the deformation joint is installed with the rubber strip and the outer side of the overlapping aluminum plate is installed. The advantage of this structure is that the outer aluminum plate is not easy to age. The disadvantage is that the aluminum plates on both sides are fixed on one side, the force is unstable, and the wind pressure resistance Not good, the gap between the aluminum plates on both sides is small, which is not enough to adapt to the displacement of the main body of the building. Under the conditions of natural disasters such as earthquakes, the aluminum plates are easily damaged;

(3) The finished deformation joints are designed and constructed by a professional team. The advantage is that the technology is mature and can accommodate the displacement of the building. The disadvantage is that it is difficult to meet the appearance effect requirements of the building skin. As the demand for building facade effects increases, the structural design of the deformation joints of the curtain wall tends to be integrated with the professional design and construction of the curtain wall.

To sum up, there is no deformation joint node structure on the market that can be used for stone curtain walls, metal curtain walls, and glass curtain walls. It can meet the functional requirements of deformation joints and curtain walls and take into account the appearance effect. It can not only meet the functional requirements of deformation joints, but also be widely promoted in the curtain wall industry, and has a good appearance effect.
