Prefabricated Slab Lifting Structure House

A prefabricated slab lifting structure house is a form of architecture that involves the industrial production of building components and their on-site assembly, belonging to a type of prefabricated assembled building. The following provides an introduction from four aspects: technical types, structural materials, application scenarios, and advantages.

Technical Types Prefabricated slab lifting structure houses encompass two main categories: prefabricated concrete structures and steel structures, with core components including prefabricated wall panels, floor slabs, beams, and columns. They can be specifically divided into two types:

1. Panel-assembled Buildings: These take prefabricated wall panels and floor slabs as core components, forming the main body of the building through on-site assembly. For example, in traditional multi-story residential buildings, the floor slabs and walls are assembled using prefabricated concrete panels, significantly improving construction efficiency.
2. Modular Buildings: These involve breaking down the building into independent modules, each integrating ceilings, floors, plumbing and electrical systems, and decorative components. These modules are prefabricated in factories and then transported to the site for assembly, creating a 'building block' construction model. For instance, the renovation project of No. 8 Huapichang Hutong in Xicheng District, Beijing, adopted concrete modular technology, planning 55 prefabricated modules. These were assembled using truck cranes, with steel bar splicing and concrete pouring techniques employed at module connections to ensure structural integrity.

Structure and Materials The main structures are divided into two categories:

1. Metal Decorative Insulation Panel Structures: These are composite structures made of carved aluminum-zinc alloy steel plates and polyurethane insulation layers, among others. The surface can exhibit decorative effects such as marble or cultured stone, combining insulation with aesthetics.
2. Concrete Module Structures: These involve the prefabrication of concrete modules in factories, which possess functions such as earthquake resistance, fire prevention, and energy efficiency. For example, in the rural revitalization project in Tianzhu County, Gansu Province, lifting houses were used as affordable housing. The concrete modules were fixed with high-strength connectors, achieving an earthquake resistance standard of 8 degrees and offering better thermal insulation and soundproofing effects compared to traditional brick-and-mortar structures.

Application Scenarios These houses are suitable for scenarios such as guardhouses, kiosks, rural revitalization projects, and affordable housing construction. For example:

• In Shimen Town, Huoshaocheng Village, Tianzhu County, Gansu Province, lifting houses were used as affordable housing, welcomed by the locals due to their short construction period (only a few weeks) and quick occupancy.
• The affordable housing project in Shenzhen, Guangdong Province, was assembled from 6,028 concrete modules, reducing the completion and delivery time from the traditional 2.5-3 years to 1 year, and decreasing on-site labor by approximately 50%.

Advantages

1. Short Construction Period: Industrial production employs parallel operations and automated production lines, shortening the construction period by more than 60% compared to traditional buildings.
2. Controllable Quality: Components are standardized and produced in factories, reducing human errors and ensuring high quality stability.
3. Energy Efficiency and Environmental Protection: Environmentally friendly materials are often used, reducing on-site wet operations and lowering dust and noise pollution.
4. Low Cost: Modular design allows for mass production, reducing overall costs and facilitating easy maintenance in the later stages.
