What Do Jiangsu Prefabricated Houses Include?
Jiangsu prefabricated houses mainly include prefabricated components centered around the 'three panels' and various prefabricated products under multiple prefabricated assembly building technology systems.
I. Core Components of the 'Three Panels'
The Jiangsu Provincial Department of Housing and Urban-Rural Development clearly states that the core components of prefabricated houses, the 'three panels,' specifically include: 1. Prefabricated Interior and Exterior Wall Panels As the main components of the building envelope structure, prefabricated interior and exterior wall panels are produced through standardized factory manufacturing, enabling rapid installation and efficient construction. Their advantages lie in reducing on-site wet operations, enhancing the overall airtightness and thermal insulation performance of the building, and meeting building energy efficiency requirements. 2. Prefabricated Stair Panels Prefabricated stair panels are molded in the factory and directly transported to the site for assembly, significantly shortening the construction period. Their standardized design ensures dimensional accuracy, reduces on-site errors, and enhances the overall safety and durability of the stair structure. 3. Prefabricated Floor Panels (Including Prefabricated Composite Floor Panels) Prefabricated floor panels are divided into two categories: fully prefabricated floor panels and prefabricated composite floor panels. Fully prefabricated floor panels are used directly as structural layers, while prefabricated composite floor panels are composed of a prefabricated base plate and an on-site cast layer, balancing construction efficiency and structural integrity. They are widely used in multi-story and high-rise buildings.
II. Components under the Prefabricated Assembly Building Technology System
The technology system for Jiangsu prefabricated houses encompasses three modes: panel assembly, box assembly, and frame assembly, with component types including: 1. Panel Assembly Components Based on the 'three panels,' these components extend to附属 (ancillary) components such as prefabricated balcony panels and air conditioning panels, forming a complete building envelope and functional system. These components enable rapid assembly and modular combination through standardized interface design. 2. Box Assembly Components These components are prefabricated in the factory as three-dimensional spatial modules (such as bathroom and kitchen boxes) and directly hoisted and assembled on-site. They integrate piping, decoration, and equipment systems, significantly improving construction efficiency and building industrialization levels. 3. Frame Assembly Components These include structural components such as prefabricated beams and columns, which form a frame system through dry connection technology. These components are suitable for high-rise buildings, achieving a balance between structural safety and construction efficiency while reducing on-site formwork usage and construction waste generation.
In summary, the component system of Jiangsu prefabricated houses is centered around the 'three panels' and extends to standardized and modular products under multiple technology modes, covering building structures, envelopes, and functional systems, and promoting the development of building industrialization towards efficiency and sustainability.
