Construction Drawing of Prefabricated House Structure
Currently, we cannot directly provide the construction drawing of the prefabricated house structure, but we can explain the key points of its structural construction in conjunction with the prefabricated house construction process.
The construction of prefabricated houses usually follows a systematic and orderly process, and its structural construction also revolves around these key links.
Foundation Fixing and Base Beam Embedding: This is the initial step in the construction of a prefabricated house. First, the fixed excavation of the prefabricated foundation is carried out, and the size and depth of the foundation are determined according to the design requirements of the house and the geological conditions. After that, the base beam is embedded. As an important supporting part of the house structure, the accuracy and stability of the base beam embedding are crucial. It needs to be able to bear the overall weight of the house and possible external forces, such as wind and earthquake forces. During the embedding process, it is necessary to precisely control the position, elevation, and levelness of the base beam to ensure that it meets the design specifications.
Basic Structure Fixing: After the foundation and base beam are ready, the fixing of the basic structure begins. Taking the Shanghai Chongming Villa Project as an example, it adopts a fully-bolted steel frame structure system. First, the production of prefabricated steel components is carried out, and steel columns, steel beams, and other components are precisely manufactured in the factory according to the fixed-length requirements. These components undergo strict quality inspections before leaving the factory to ensure that their dimensional accuracy, strength, and other indicators meet the standards. After the foundation is completed, the steel columns and steel beams are installed in sequence and firmly connected by bolts to form the basic frame structure of the house. This frame structure provides stable support for the subsequent installation of walls, floors, etc.
Auxiliary Component Installation and Overall Structure Completion: After the basic structure is fixed, the installation of auxiliary components such as fixing auxiliary bolts is carried out to further enhance the structural stability. Subsequently, ALC wall panels, floor slabs, and other components arrive at the site and are installed. ALC panels have the advantages of being lightweight, high-strength, and having good thermal insulation. During the installation process, it is necessary to ensure that they are tightly connected to the steel frame structure to ensure the integrity and airtightness of the house. Finally, the roof is installed to complete the structural construction of the entire prefabricated house. The entire process needs to be carried out in strict accordance with the design drawings and construction specifications to ensure the quality of each link, thereby ensuring the safety and reliability of the prefabricated house structure.
