Description

Technical Field

[0001] This invention relates to the field of building curtain wall engineering technology, and in particular to an ultra-heavy concrete composite panel curtain wall system and its construction method. Background Technology

[0002] This project involves the exterior curtain wall structure of a circus theater. As a large-scale public cultural building, the curtain wall of the circus theater must meet the requirements of high strength, high safety, adaptability to complex shapes, and special functions. Similarly, due to structural design requirements, this project also adopts an ultra-heavy concrete composite panel curtain wall system. However, in current building curtain wall engineering, the ultra-heavy concrete curtain wall system faces the following technical bottlenecks: 1. Load-bearing and installation challenges: The installation of ultra-heavy concrete panels (such as those with large thickness and composite structures) lacks an efficient and reliable connection system. Traditional support components have insufficient load-bearing capacity, which can easily lead to structural deformation or connection failure, posing safety hazards. 2. Adjustment limitations: Existing connectors are mostly rigidly fixed, making it difficult to achieve three-dimensional fine-tuning of the panels during construction (such as horizontal and vertical position correction), resulting in low installation accuracy and poor adaptability. 3. Low construction efficiency: Complex connection structures lead to cumbersome hoisting, positioning, and fixing procedures, especially time-consuming handling of the first floor and irregular nodes, extending the construction period.

[0022] Compared with the prior art, the present invention has the following features and beneficial effects.

[0023] 1. Current curtain wall improvement solutions for theater buildings mostly focus on local shape adaptation, without systematically solving the problems of three-dimensional adjustment of heavy-duty panels, dynamic load transfer, and integrated fireproofing and sound insulation. Although elastic supports are introduced in some structures, installation accuracy and load-bearing efficiency are sacrificed, making it difficult to meet the high load and high precision requirements of theaters. In contrast, the heavy-duty concrete composite panel proposed in this application only requires four steps on-site: "hoisting, coarse adjustment, fine adjustment, and fixing," thus shortening the overall construction period.

[0024] 2. The ultra-heavy concrete composite panel curtain wall system adopted in this invention has high load-bearing capacity and stability: both the first and second connecting components adopt split support to form a three-dimensional force system, which disperses the ultra-heavy panel load to the main structure and effectively improves the load-bearing capacity of a single point; at the same time, a fixed connector is designed in the first connecting component, and the ultra-heavy concrete composite panel is plug-welded after adjustment. The first connecting component, through a composite mechanism of rigid connection and adjustable support, ensures the safety of the ultra-heavy panel curtain wall structure while taking into account the construction flexibility and economy.

[0025] 3. This invention achieves precise connection of heavy-duty concrete composite panel curtain walls through the coordinated operation of the first vertical adjusting bolt and the first horizontal adjusting bolt. The first vertical adjusting bolt controls the elevation, and the first horizontal adjusting bolt provides horizontal positioning. This solves the drawback of irreversible traditional welding fixation. At the same time, a two-way adjusting component, the second vertical + horizontal adjusting bolt, is set on the upper part of the heavy-duty concrete composite panel to cooperate with the top connecting keel, simplifying the difficulty of high-altitude alignment and greatly shortening the installation time of the heavy-duty concrete composite panel.

[0026] 4. This invention embeds support components, external support components, a first threaded sleeve, and a second threaded sleeve into the precast concrete composite panel, enabling modular hoisting on-site, reducing on-site welding and lowering labor costs. Simultaneously, this application constructs a "three-dimensional adaptive" system for the ultra-heavy concrete composite panel curtain wall through rigid plug welding and adjustable supports in the first connecting component, stepless horizontal adjustment of the second connecting component, and bidirectional top coordination of the third connecting component. This achieves breakthroughs in structural safety, construction efficiency, and functional adaptability, particularly suited to complex architectural scenarios with high dynamic, high precision, and high aesthetic requirements, such as acrobatic theaters.
