On February 6, 2016, the Central Committee of the Communist Party of China and the State Council issued several opinions on further strengthening urban planning and construction management, proposing the development of new construction methods, vigorously promoting prefabricated buildings, reducing construction waste and dust pollution, shortening construction periods, and improving project quality. Develop specifications for the design, construction, and acceptance of prefabricated buildings. Improve component standards and achieve factory production of building components. Encourage construction companies to carry out prefabricated construction and on-site assembly. Increase policy support and strive to achieve a 30% proportion of prefabricated buildings in new construction within about 10 years..

Mode 2=Welding keel+hanging plate mode+on-site spraying;.

1) On site construction heavily relies on manual labor and experience, resulting in a long construction period; A large amount of manual work has led to a shortage of experienced teams and a rise in labor prices; The labor costs of construction enterprises have increased significantly..

5) Due to the large welding workload, it not only affects the environment but also causes significant damage to the eyes and faces of construction workers..

During construction, a large number of keels need to be welded on site. Due to the high height of the purification area, the rigidity of the keels is poor, and the welding construction produces high-temperature deformation, making it difficult to ensure the flatness and verticality of the keels, resulting in uneven wall panels in the later stage. Welding can cause significant damage to the human eye and face..

2) Easy and convenient installation, quick to get started (even for inexperienced construction teams), and short construction period;.

The adhesive strip only needs to be pushed and installed during the installation process of the hanging board, which is convenient and fast. It not only standardizes the spacing between boards, but also ensures the sealing and aesthetics of the wall..

3. Fire resistance: The maximum fire resistance can reach Class A, and the maximum fire resistance limit can reach 1 hour..

4. Environmental friendliness: 1) The structure itself and the adhesive used in synthesis are completely free of organic volatiles such as formaldehyde.

2) On site assembly does not require adhesive, only screws are used for connection, and no cutting or construction waste is generated.

3) The structural framework is made of aluminum material, which is 100% environmentally friendly and recycled material.

5. Diversity of choices: With the same standard components, the surface material can be selected from various options such as metal plates (stainless steel plates, electrolytic steel plates), tempered glass plates, etc., and the surface color can be selected..

2) Practical hollow adjustable louvers and transparent design of frosted glass after power on.

The overall factory prefabrication improves installation efficiency and greatly shortens the construction period. An operating room only requires 3 workers and can complete assembly construction in 2-3 days. Compared to traditional construction techniques, it saves nearly 70% of the construction period..

Each board can support up to 3 people, laying the foundation for overall installation and future maintenance inside the ceiling..

Fire resistance reaches A1 level, with a fire resistance limit of over 1 hour..

·No welding required (reducing fire safety hazards and high-temperature deformation issues);.

·No need for glue (ensuring green and environmentally friendly construction environment);.

·No need for anti rust paint (no fire hazards and organic volatiles);.

·No need for cutting (reducing noise pollution and dust) to avoid generating construction waste..

The traditional keel wall can be as few as 70-100mm, but now Suzhou Tongkuai integrated panel has a minimum of 44mm and a maximum thickness of 55mm, and can be reserved for passing through in the middle.
