China Railway Urban Construction Beijing Company organized to carry out prefabricated building observation and learning

Prefabricated building refers to a building assembled from prefabricated parts and components on the site. It has the advantages of fast construction progress, energy saving and environmental protection, cost reduction and efficiency increase. In recent years, with the country's vigorous advancement, the development of prefabricated buildings is an important measure to promote supply-side structural reforms and the development of new urbanization. It is the concrete embodiment of the construction industry's implementation of the concept of green development and innovative development. It is an important starting point for promoting the transformation and upgrading of the construction industry and realizing the modernization of the construction industry. It is the only way for the development of the construction industry.

The project adopts a prefabricated frame structure system, the interior and exterior walls use prefabricated fabricated wall panels, the bathroom and balcony partial floor slabs are cast in place, and the rest of the floor slabs are all prefabricated laminated floor slabs. In the site model display area, everyone first listened to a detailed introduction of the construction of the prefabricated building, and had a preliminary understanding of the prefabricated frame structure system of the project. Then, under the leadership of the on-site technical person in charge, went to the construction site to observe the construction process of the prefabricated building. The observers took out their mobile phones to record the hoisting and installation of prefabricated wall panels, and the sleeve grouting process. At the same time, they communicated with the technical person in charge of the site on issues such as vertical component hoisting, correction, laminated board installation, number of installers, mechanical equipment selection, construction schedule, cost control, and difficulties in prefabricated construction.

The observers then visited the pilot building of Yugou Company and the new material display area. By watching various types of precast concrete components, prefabricated structural nodes, prefabricated system nodes, prefabricated building construction processes and completed products, we have an in-depth understanding of the entire construction process of prefabricated buildings.

Through this observation and learning, the observers not only learned the experience of prefabricated building construction, but also broadened their horizons and ideas. Everyone said that they would take this observation and learning activity as an opportunity to absorb the excellent practices of prefabricated construction in many ways, and improve the company's construction technology management level and technical strength. It can better meet the needs of future construction industrialization development and contribute to the company's sustainable and healthy development.
