The integrated thermal insulation superimposed wall of Sany construction structure was selected as the first batch of intelligent construction and prefabricated construction integration products and technologies in Changsha City

In order to accelerate the construction of a modern industrial system, strengthen the systematic and integrated construction of buildings, improve the product system of new building industrialization technology with integration as the core, create a supply chain of intelligent construction prefabricated parts and components, promote the application of prefabricated decoration, promote the implementation of new construction methods and management models of [(BIM+M)+EPC], and help the industry improve quality, reduce costs and increase efficiency, Changsha Municipal Bureau of Housing and Urban-Rural Development has determined that 39 products and technologies such as "structural insulation integrated superimposed wall" will be included in the " Changsha City's first batch of intelligent construction prefabricated construction integration products and technology list", and released.

In that list,Trinity ConstructionThe SPCS structural insulation integrated superimposed wall ranked first in the enclosure and structural category. This is after the 4 technologies of Sany Construction Engineering were selected into the list of new practical technologies in the field of intelligent construction in Changsha in 2024, Sany Construction Intelligent Construction Technology has once again been officially certified by the local government, demonstrating Sany Construction's technological leadership in the field of construction industrialization. As a pioneer in intelligent construction technology, Sany Construction Engineering is providing the core driving force for the transformation of the traditional construction industry to industrialization and digitalization through continuous iteration of the "technology, equipment and cloud platform".

SPCS structure insulation integrated superimposed wall is a kind of wall system that adopts the reverse beating process, and the insulation layer and the superimposed concrete wall are compounded in the factory, and the outside of the insulation layer is plastered after the insulation is reversed. At this stage, the external wall insulation technology used in China mainly includes external wall insulation technology, external wall insulation technology and sandwich insulation technology, in which the sandwich insulation cost is high, there is a risk of warping, and the traditional construction technology is easy to crack, easy to fall off, the actual service life is limited, and the construction is cumbersome. With the continuous improvement of fire protection requirements and energy-saving requirements, relevant policies to encourage the development of integrated technology for thermal insulation structure decoration have been introduced. With its excellent performance, building life, safety and reliability, and convenient construction, prefabricated structure thermal insulation integrated exterior wall will become the leading direction and inevitable trend of comprehensively promoting the research of energy-saving building wall insulation engineering technology.

SPCS structure thermal insulation integrated superimposed wall structure

SPCS structure insulation integrated laminated wall has the following advantages:

1. Thermal insulation and self-fire prevention

The insulation layer is made of non-combustible materials, which is water-repellent and moisture-proof, which can eliminate heavy concrete leaf slabs, greatly simplify the structure and reduce costs.

2. Fast construction

One-time molding, reduce the on-site insulation post-paste work, and the outermost surface flatness is high, which can realize thin plastering or even no plastering of the decorative layer.

3. Good quality is safer

The insulation layer and the enclosure/structural wall are integrated and compounded in the factory, eliminating the process of manual application of adhesive and insulation punching on site, the quality is more controllable, and the safety risk of insulation falling off is avoided.

4. Adaptable

It is suitable for all regions of the country, and it is recommended to focus on Beijing-Tianjin-Hebei, Shaanxi, Shanxi, Henan, Shandong and other severe cold and cold climate areas, as well as Hunan and other areas that encourage the application of external wall thermal insulation. Our company has formed a variety of regional solutions based on the main regions of the country, combined with local materials.

According to the requirements of fire prevention and thermal insulation and the characteristics of the project, the product integrates the production of the insulation layer and the SPCS cavity prefabricated wall in the factory, which can simplify the production and on-site operation of the factory, realize the integration of structure, thermal insulation, fire prevention and decoration, and the same life of insulation and building, and integrate the dual functions of structural load-bearing and building insulation, so as to achieve "excellent structural safety cost, green wisdom and fast saving". Sany Construction will continue to provide technology, equipment and cloud platforms for intelligent construction to help achieve the "double carbon" goal and the transformation and upgrading of the industry.
