Hoisting Prefabricated Panel House

A hoisting prefabricated panel house is a prefabricated building that can be hoisted and moved as a whole by a crane without the need for disassembly, featuring various characteristics and construction methods.

Main Components:

• The main body of a hoisting prefabricated panel house can be composed of metal decorative insulation panels or concrete modules. For metal decorative insulation panels, for example, the panels are made by compounding carved aluminum-zinc alloy steel plates with polyurethane insulation layers. These panels can display decorative effects such as marble and cultural stone on their surfaces, which are not only aesthetically pleasing but also have certain insulation properties. Concrete modules are prefabricated in factories and then hoisted on-site, possessing functions such as earthquake resistance, fire prevention, and energy conservation, meeting the requirements of modern buildings for safety and energy efficiency.

Connection Methods:

• In concrete modular construction technology, each module includes electromechanical pipelines and decorative components, which are assembled on the construction site through truck hoisting. The joints between modules adopt on-site steel bar splicing and concrete pouring techniques. This connection method ensures a firm connection between modules, improving the overall structural stability of the house, enabling it to better maintain structural integrity when facing various external forces, such as earthquakes.

Historical Applications and Shortcomings:

• Prefabricated panel houses have been widely used historically. From the 1970s to the mid-1990s, a large number of residential buildings were constructed using prefabricated panels. At that time, the prefabricated panels were pre-made reinforced concrete floor slabs in factories, which were directly hoisted, erected, and spliced on the construction site, followed by plastering. This construction method significantly shortened the construction period and improved construction efficiency. However, prefabricated panel buildings also have some inherent shortcomings. Due to their structural characteristics, their earthquake resistance is relatively weak. In the event of an earthquake, the buildings are prone to damage, posing a threat to the lives of occupants. At the same time, the panel joints are prone to cracking and water leakage, which not only affects the aesthetics of the buildings but also has adverse effects on the structural safety and service life of the buildings, requiring a certain amount of cost for maintenance and upkeep in the later stage.
