At the same time, the company has built an area of 350 mu (about 233000 m2) in the Qian’an Base of Shougang, with an annual production capacity of 300000 meters ³ ALC board production line.

Click to subscribe to the editor’s note of the two issues in 2023: In recent years, China’s industrialization of new buildings represented by precast buildings has been rapidly advancing, the standards and specifications have been continuously improved, and the construction level and construction quality have been significantly improved, setting off the climax of the development of precast construction.

During the “13th Five-Year Plan” period, the company established the precast construction business unit, aiming at building a leading enterprise of precast steel structure construction, comprehensively promoting the construction of the entire industrial chain of precast construction, and was recognized as the national precast construction industrial base by the Ministry of Housing and Urban-Rural Development.

Integrated kitchen and bathroom, elevated floor and other decoration integration technologies have been applied, and the seismic performance is extremely excellent.

The four key projects of Shougang’s construction of Qian’an Autoclaved Aerated Products Production Base, Shougang’s construction of Tangshan Harbor Steel Structure Processing Base (I) The first precast high-rise steel structure residential building in Beijing, the public rental housing project of Beijing Mentougou Lead Wire Factory, adopts the steel frame-concrete core tube steel structure residential system, with a building area of 21283 ㎡, 20 floors above the ground, 2 floors underground, and a building height of 54.98 m.
.

The construction of Shougang has always been committed to the research and development and practice of precast steel structure buildings, relying on the advantages of Shougang’s steel industry, and has comprehensive capabilities in the whole industrial chain of precast buildings such as real estate development, design and development, manufacturing and construction, smart home, etc.

Shougang Construction, together with Shougang International, Shougang Real Estate, Shougang Technology Research Institute and other units, has jointly developed Shougang precast high-rise steel structure residential building, and developed a complete set of technologies suitable for industrial promotion of high-rise steel structure residential building, A series of key problems restricting the development of steel structure housing have been solved.

(hereinafter referred to as “Shougang Construction”) was established in 1956, and has a number of general contracting and professional contracting qualifications, such as metallurgical general contracting, housing construction, steel structure, municipal, electromechanical installation, etc.

（2） Component production advantages The company has a complete production capacity of core components of precast steel structure buildings.

Development history Beijing Shougang Construction Group Co., Ltd.

The product has the characteristics of simple structure system, strong applicability and easy promotion.

Innovative wall-panel assembly and interior decoration node processing technology have been developed.

This technology has successively won the first prize of Shougang Group’s scientific and technological achievements in 2020, the first prize of China Construction Enterprise Association’s scientific and technological achievements and other honors.

In order to fully display the struggle process of precast construction base enterprises, carry forward the spirit of model workers, and fully publicize the important role and outstanding contributions of the leading enterprises, the Ministry of Housing and Urban-Rural Development’s construction magazine has launched a special column of “National Assembly Construction Leading Enterprise Tour” in the whole media, focusing on the beneficial exploration and accumulated valuable experience of the leading enterprises in the development process of precast construction base, Focus on displaying the core advantages, development vitality and style of the base’s leading enterprises.

Since the two production bases were put into operation, they have completed more than 1.5 million square meters of precast steel structures, making positive contributions to promoting the development of precast buildings.

Among them, the developed integrated design+industrial construction technology has improved the quality of steel structure housing; The developed flexible connection+composite retaining wall technology has solved the problems of air tightness, water tightness and crack prevention of the supporting external wall of the steel structure residence; The developed weathering steel preparation and application technology has improved the durability and safety of steel structure housing.

Shougang Construction has been engaged in the field of precast buildings since the 1980s, taking the lead in completing the construction of 3 million m2 precast buildings in Shijingshan District; The research and exploration of precast steel structure housing began in 1996; In 2012, EPC mode was adopted to build the first precast high-rise steel structure residence in Beijing, which has accumulated practical experience for the research and development of key technologies of steel structure residence.

It has obtained 24 authorized patents (including 7 invention patents), participated in the compilation of 1 national standard, 5 local and industrial standards, edited 3 enterprise standards, published 3 papers, and 2 construction methods have been recognized as provincial and ministerial construction methods.

The national precast construction industry base has become an important carrier and grip for the high-quality development of China’s new construction industrialization, and an important driving force for the transformation and upgrading of China’s construction industry.

In 2018, the Tangshan Seaport Steel Structure Processing Base with an area of 432 mu (about 288000 m2) and an annual capacity of 50000 tons was built.

and China Institute of Architectural Design and Research jointly developed the precast steel housing with box panels, and built the housing with the concept of shipbuilding, achieving the goal of 100% assembly, 100% decoration and 100% recyclability.

Shougang precast steel structure residential building is based on the concept of domestic existing capacity, green environmental protection and circular economy.

The company has developed Shougang’s own steel structure residential products; The R&D and exhibition base of Shougang precast buildings covering an area of 12000 m2, and the production base of steel structure and ALC wall panels have been built; Completed the construction of more than 3 million square meters of precast buildings, and built a general contracting capacity with construction as the core; It has successively undertaken the research and landing of six projects (projects), including the research and development project of Beijing Municipal Commission of Science and Technology “Industrialized design and construction of green precast high-rise steel structure housing”, the key research and development project of the Ministry of Science and Technology “13th Five-Year Plan”, “High-efficiency assembly connection technology and demonstration of steel structure buildings”, and the scientific and technological Winter Olympics special project “Research on fine construction technology of competitive artificial section track”, It has played a positive exemplary and leading role in the development of precast buildings.

Three core advantages of Shougang precast building R&D and exhibition base (I) Product R&D advantages 1.

The building’s enclosure structure and floor are made of all-steel plates.
