Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building curtain wall, more specifically, relates to a fabricated thermal insulation dry hanging stone integrated composite curtain wall and a construction method thereof. BACKGROUND

[0002] In the continuous progress of the construction industry, the promotion of fabricated buildings has become an important trend in the development of the industry. In this context, the dry hanging construction technology of the outer wall has gradually replaced the traditional wet operation construction method. The dry hanging stone technology of the outer wall uses high-strength and corrosion-resistant metal hanging parts, adopts various fixing methods such as support, suspension, pin and bolt, and firmly installs decorative stone on the outer surface of the building. This construction technology not only avoids the pollution and discoloration phenomenon of the stone surface caused by wet operation, i.e. so-called "reverse alkali", but also maintains the original color and luster of the stone. In addition, due to the reduction of dependence on weather conditions, the dry hanging construction technology of the outer wall also helps to save the additional cost of construction in winter and rainy season, thereby improving the construction efficiency and economic benefits.

[0003] In the prior art, a dry hanging structure of a concave stone curtain wall based on a steel skeleton is disclosed in Chinese patent CN220353183U, which is arranged at the interlayer structure, located between the upper and lower glass curtain walls, and includes a steel skeleton installed on the structure, stone plates installed on the top surface and the outer side surface of the steel skeleton, and honeycomb stone installed on the bottom surface of the steel skeleton. The stone plates and the honeycomb stone enclose the steel skeleton to form a concave structure. A closing edge rail is arranged between the top surface of the steel skeleton and the glass curtain wall. The closing edge rail is fixed with a steel column through a connecting piece. The end of the closing edge rail is sealed with sealing glue and a foam rod between the closing edge rail and the stone plate. A water guide plate is installed on the closing edge rail, one end of which is connected with the closing edge rail and the other end is pasted on the top surface of the stone plate.

[0004] The dry hanging structure of the above-mentioned patent combined with the glass curtain wall can increase the visual effect of the curtain wall structure. In addition, cooperating with the honeycomb stone at the bottom, it is convenient to discharge the infiltrated water in the stone curtain wall and reduce the influence on the building. However, it still cannot solve some problems existing in the construction of traditional dry hanging structure and curtain wall: (1) The dry hanging rail structure is connected with the main structure by subsequent hole digging, bolt embedding and galvanized steel plate, which causes damage to the structure beam and generates a lot of dust, which is not conducive to safe and civilized construction; (2) The main and secondary rails have many welding points, the construction period is long, and after welding, anti-rust paint needs to be sprayed, which is not conducive to the installation of thermal insulation rock wool, and there are many fire hazards in the construction process; (3) Some stones are connected with the rail only through dry hanging glue, which is easy to age and fall off in extreme weather and for a long time. SUMMARY

[0005] In view of the above defects or improvement needs of the prior art, the present application provides an assembled thermal insulation dry hanging stone integrated composite curtain wall and a construction method thereof.
