Description

Technical Field

[0001] The invention relates to an aluminum plate curtain wall with an upright quadrangular pyramid grid roof and a built-in snow melting system eaves and a construction method thereof, belongs to the field of house construction, and is suitable for the construction of curtain walls and snow melting systems on the exterior walls of large-scale special-shaped buildings. Background Art

[0002] With the rapid development of science and technology and the continuous innovation of glass material manufacturing technology, the outstanding performance of glass curtain walls in quality, transparency and safety has become more and more significant, which has greatly promoted the vigorous expansion of the relevant market size. At the same time, the general improvement of environmental awareness has prompted the construction industry to tend to adopt low-carbon and high-efficiency design concepts. As an important member of this trend, the market demand for glass curtain walls is growing due to its unique advantages. However, with this rapidly growing market trend, the problem of building quality has become increasingly prominent, especially the quality of building exterior wall structures, which has become the focus of social attention. In the context of the current accelerated urbanization process, people have put forward higher standards and requirements for the safety and durability of building structures. Therefore, one of the important tasks facing construction companies is to strengthen technical research and development and continuously improve the construction technology of building structures. In particular, in-depth research and development of exterior wall structure construction technology is particularly critical. Through technological innovation, improving the construction quality of the exterior wall can not only ensure the overall safety and service life of the building, but also further improve the energy efficiency and environmental protection performance of the building, and meet the society's expectations for high-quality buildings.

[0003] The existing technology has the following deficiencies: (1) In the existing steel keel and concrete structure connection technology, the vertical keel is not directly stressed, and the connection between the keel and the building body is not firm. (2) The application of large keels is gradually becoming less common, and the irregularly shaped keel units cannot be fixed and positioned on the ground, making construction and assembly inconvenient. (3) The "ice cone" and other shapes formed at the eaves will suddenly fall off when melting, which may cause a certain degree of damage to the gutter surface and other structures, thereby destroying the gutter structure and causing gutter seepage.

[0004] For the construction of aluminum curtain wall at the eaves of a square pyramid grid roof with a built-in snow melting system, it is urgent to propose a construction method that can improve construction efficiency while ensuring project quality and safety. Summary of the invention
