Shenyang City, Liaoning Province strengthens the application of external wall panels and promotes the development of prefabricated buildings

On September 23, the reporter learned from the Shenyang Urban and Rural Construction Bureau that with the gradual growth of industrialization, the modern construction industry has become an important pillar industry in Shenyang. As one of its important parts and materials, exterior wall panels play an increasingly important role in realizing the transformation and upgrading and high-quality development of the prefabricated building envelope system.

As one of the series of activities to promote energy-saving and green "four new" technologies in Shenyang, the integrated technology of building insulation and structure enables simultaneous construction of building wall insulation and main structure. At the same time, the thermal insulation and the main wall form a composite structure through the prefabricated composite thermal insulation and non-demoulding formwork board, so that the building thermal insulation and the wall have the same life span, and a series of quality problems and safety hazards such as hollowing, cracking and falling off of the traditional thermal insulation layer are completely eliminated.

It is understood that the prefabricated composite thermal insulation and non-demoulding formwork board is produced in the factory and assembled on-site. The thermal insulation formwork and concrete are firmly connected through connectors to form an insulation structure system. It eliminates the need for external thermal insulation construction of external walls and reduces construction costs. Since the advent of product technology, with its five characteristics of "lightness, thinness, economy, flatness, and speed", it has demonstrated many advantages in market applications, fully meeting the construction needs of industrial and civil building thermal insulation and structural integration projects. In addition, its thermal insulation and fire resistance performance is excellent, the quality is safe and reliable, and it can fully realize the same life span as the wall body.

Chen Yan, general manager of Shenyang Xinyizhou Thermal Insulation Material Co., Ltd., told reporters that in general building thermal insulation, the main inorganic thermal insulation materials used are rock wool and its products. Nowadays, the external wall thermal insulation panels used are continuously upgraded. In addition to good thermal insulation and fire prevention effects, the prefabricated composite thermal insulation and non-demoulding formwork board also eliminates a series of quality problems and safety hazards such as bulging, cracking, water seepage, and falling off in traditional thermal insulation. It reduces the construction period and engineering cost, and at the same time avoids environmental pollution, which can effectively save energy and protect the environment.

The relevant person in charge of the Shenyang Urban and Rural Construction Bureau introduced that building energy conservation and the promotion of green buildings are important measures to promote the green and high-quality development of urban and rural construction. It is of great significance for saving resources, protecting the environment, achieving energy saving and emission reduction goals, improving the living environment, and driving the development of energy saving industries.

In order to meet the construction needs of the comprehensive promotion of low-energy buildings and green buildings, Shenyang City vigorously promotes the engineering application of the “four new” technologies for building energy saving, improves the construction quality and overall quality of energy-saving buildings, and drives the development of energy-saving industries. Building energy efficiency and green buildings implement new development concepts, focusing on “quality improvement, green transformation, and innovation-driven” to promote the energy-saving upgrade of new buildings and the overall promotion of green buildings. And in promoting the application of green energy-saving "four new" technology products and other aspects, intensify work to lay a solid foundation for the comprehensive realization of green and high-quality development of construction engineering.
