Crane Installation of Prefabricated Concrete Houses
The installation of prefabricated concrete houses using cranes is a process that involves multiple steps and requires meticulous operation, mainly including crane entry preparation, component positioning, lifting operations, foundation coordination, and team collaboration.
Crane Entry and Component Positioning: Trucks transport prefabricated components to the construction site and wait by the roadside. For example, during the installation of the prefabricated concrete house for Mr. He's villa in Shaoshan, the truck carrying the components waited by the roadside for the first component to be lifted. This step requires advance planning of the transportation route and component placement positions to ensure that the components can smoothly reach the designated locations and prepare for subsequent lifting work.
Key Points of Lifting Operations: During lifting, it is essential to fully consider surrounding environmental factors. Objects such as power lines that may obstruct the crane's angle adjustments should be cleared or protected in advance to avoid collisions during lifting, which could affect lifting safety and progress. For prefabricated buildings like lifting houses that are moved as a whole by cranes without disassembly, their main bodies are composed of concrete modules. These modules are prefabricated in factories and then lifted on-site, possessing functions such as earthquake resistance, fire prevention, and energy efficiency. During lifting, an appropriate crane should be selected based on the weight and size of the components. For example, when a 50-ton crane is used to lift a concrete house, professionals ensure that the crane safely passes through narrow areas such as gates and avoids collisions to guarantee the safety and stability of the lifting process.
Foundation Coordination: In the lifting and construction of multiple prefabricated concrete houses, the design of the foundation is crucial. The foundation design needs to consider the stability of the houses and the possibility of other uses, ensuring that the houses can be firmly fixed on the ground after lifting, withstand various external forces, and guarantee residential safety.
Team Collaboration: The entire lifting process requires operation by a professional team, with meticulous team collaboration. From the lifting, moving, and positioning of components, each step requires close cooperation among team members and strict adherence to operating procedures to ensure the smooth progress of the lifting work. The installation of prefabricated concrete houses using cranes is applied in some regions due to its short construction period and simple installation.
