Description

Technical Field

[0001] The present invention belongs to the technical field of building curtain walls, and more specifically, relates to an assembled thermal insulation dry-hanging stone integrated composite curtain wall and a construction method thereof. Background Art

[0002] With the continuous progress of the construction industry, the promotion of prefabricated buildings has become an important trend in the development of the industry. Against this background, the exterior wall dry hanging construction technology, with its characteristics of prefabrication and assembly, has gradually replaced the traditional wet operation construction method. The exterior wall dry hanging stone technology uses high-strength and corrosion-resistant metal hangers and adopts a variety of fixing methods such as brackets, hangers, pins, and bolts to firmly install decorative stones on the outer surface of the building. This construction technology not only avoids the pollution and discoloration of the stone surface caused by wet operations, the so-called "anti-alkali", but also maintains the original color and gloss of the stone. In addition, due to the reduced dependence on climatic conditions, the exterior wall dry hanging construction technology also helps to save the additional cost of construction in winter and rainy seasons, thereby improving construction efficiency and economic benefits.

[0003] In the prior art, a Chinese patent with document number CN220353183U discloses a dry hanging structure of a concave stone curtain wall based on a steel frame, which is arranged at an interlayer structure and located between upper and lower glass curtain walls, and includes a steel frame installed on the structure, a stone plate installed on the top surface and outer side surface of the steel frame, and a honeycomb stone installed on the bottom surface of the steel frame, wherein the stone plate and the honeycomb stone enclose the steel frame to form a concave structure; an edge trimming keel is arranged between the top surface of the steel frame and the glass curtain wall, the edge trimming keel is fixed to the steel column by a connector, the end of the edge trimming keel is sealed to the stone plate by a sealant and a foam rod, a water guide plate is installed on the edge trimming keel, one end of the water guide plate is connected to the edge trimming keel, and the other end is adhered to the top surface of the stone plate.

[0004] The combination of the dry hanging structure and the glass curtain wall of the above patent can enhance the appearance of the curtain wall structure. In addition, the honeycomb stone at the bottom facilitates the drainage of water seepage in the stone curtain wall and reduces the impact on the building. However, it still cannot solve some problems existing in the traditional dry hanging structure and curtain wall construction: (1) The dry hanging keel structure is connected to the main structure through subsequent hole drilling and buried bolts and galvanized steel plates, which causes certain damage to the structural beams and generates a lot of dust, which is not conducive to safe and civilized construction; (2) There are many welding points in the welding construction of the primary and secondary keels, and the construction period is long. Anti-rust paint needs to be sprayed after welding, which is not conducive to the installation of thermal insulation rock wool, and there are many fire hazards during the construction process; (3) Some stones are connected to the keel only by dry hanging glue, which is prone to aging and falling off in extreme weather and over a long period of time. Summary of the invention

[0005] In view of the above defects or improvement needs of the prior art, the present invention provides an assembled thermal insulation dry-hanging stone integrated composite curtain wall and a construction method thereof, wherein the multifunctional wall panel is placed on the positioning and reinforcement unit by connection methods such as bolts, clamping and bonding, thereby avoiding the problem of easy falling off in a single connection method, and effectively increasing the integrity of the multifunctional wall panel by adopting integrated construction technology, so that the thermal insulation and energy-saving effects are significantly enhanced, thereby effectively improving the practicality of the composite curtain wall; secondly, the support unit and the positioning and reinforcement unit, as well as the support unit and the structural column are connected and fixed by bolt connection, thereby avoiding damage to the main structure, and avoiding traditional welding operations and rust-proof treatment operations of welding nodes, thereby reducing fire hazards in the construction process and significantly improving construction efficiency.
