A curtain wall large decorative strip connection structure

Abstract

The invention provides a curtain wall large decorative strip connection structure which comprises a plurality of curtain wall units. Each curtain wall unit comprises a glass plate, a first male upright column and a first female upright column, wherein the first male upright column and the first female upright column are arranged on the two sides of the glass plate. A decorative unit is arranged between every two adjacent curtain walls. Each decorative unit comprises a sealing plate, a second male upright column and a second female upright column, wherein the second male upright column and the second female upright column are arranged on the two sides of the sealing plate, and a cross beam is arranged between the second male upright column and the second female upright column; an adapter is arranged in the middle of the cross beam and penetrates trough a U-type slot in the sealing plate, the adapter is closely sleeved with a sealing gasket, the sealing gasket is attached to the edge of the U-type slot of the sealing plate through structural glue, the outer end of the adapter is connected with a vertical supporting element, and the supporting element protrudes out of the plane of the glass plate; a first side plate is fixedly arranged on the side wall of the second male upright column, and a second side plate is fixedly arranged on the side face of the second female upright column; decorative plates are fixedly arranged between the first side plate and the outer end of the supporting element and between the second side plate and the outer end of the supporting element respectively. The curtain wall large decorative strip connection structure is reasonable in structural design and good in waterproof effect.

Description

technical field [0001] The invention relates to the technical field of building curtain walls, in particular to a large decorative strip connection structure for curtain walls. Background technique [0002] In recent years, with the rapid development of the construction industry, the design of building curtain walls has become increasingly diversified. In order to effectively enrich the facade effect of the building and realize the architectural concept, designers usually use some large decorative strips with gradual cross-sections. [0003] Taking a curtain wall project as an example, the maximum negative slope of the entire corner of the building is 7.2°, and the maximum concave distance is about 4.7m; the design of large decorative strips should meet the following characteristics: a. The angle remains unchanged, and the size of both sides of the decorative strip changes gradually; b. It is convenient to replace the glass on both sides of the glass unit; c. The decorative...

AI Technical Summary

Problems solved by technology

The change in the workload of drawing processing drawings brought about by subtle changes is huge, and increases the technical difficulty of factory processing, which cannot be processed in batches and reduces processing efficiency; during on-site construction, construction personnel need to accurately distinguish between panels There are subtle differences, once an installation error occurs, the additional workload is inestimable, which increases the difficulty of construction and reduces the construction efficiency; b. Glass replacement needs to dismantle the entire decorative strip, for large decorative strips in super high-rise buildings The difficulty of disassembly can be imagined; c. Ordinary aluminum plates are connected by screws. We all know that the pull-out resistance of screws is much smaller than the shear resistance of screws, so this connection is relatively weak against the resistance perpendicular to the aluminum plate surface; d. If the aluminum plate wants to fold out the edge and corner effect, it needs to plan grooves, which greatly reduces the bearing capacity of the aluminum plate. In addition, considering that the large decorative strip needs to reflect the light emitted from other positions, the flatness of the decorative panel is also very high.

In addition, the waterproof performance of the large decorative strips of the existing curtain wall is not enough, and the seal is often cracked due to vibration, thereby destroying the waterproof structure
