Prefabricated Assembly House Specification

The prefabricated assembly house specification covers multiple aspects, with different specification documents having different focuses. Here is a detailed introduction:

Scope of Application and Basic Principles

The "Technical Guidelines for the Construction of Prefabricated Rural Houses in Shandong Province" will come into effect on July 1, 2026. It applies to rural residential houses assembled on-site from components prefabricated in whole or in part in factories. Construction should adhere to the principles of modern functionality, structural safety, cost-effectiveness, environmental friendliness, and harmonious aesthetics, taking into account local climate, topography, traditional cultural customs, and architectural characteristics to meet the functional requirements of modern rural residents.

Structural Systems

The "Technical Guidelines for the Construction of Prefabricated Rural Houses in Shandong Province" specifies various structural systems, including prefabricated concrete shear wall structural systems, EPS module cast-in-place concrete structural systems, and light steel frame structural systems, among others, and provides detailed design and construction specifications. This offers multiple options for the structural design of prefabricated rural houses, allowing for reasonable selection based on different regions and needs.

Material Requirements

Also stipulated in the "Technical Guidelines for the Construction of Prefabricated Rural Houses in Shandong Province" is that materials should be selected based on local conditions and available resources, favoring green and economical building materials or recyclable building materials; under the premise of ensuring quality, priority should be given to using local building materials; the use of high-energy-consuming and excessively polluting materials is prohibited, reflecting the concept of environmental friendliness.

Design Requirements

The "Technical Guidelines for the Construction of Prefabricated Rural Houses in Shandong Province" points out that design should respect the housing needs of farmers, with architectural styles reflecting regional characteristics and appropriate consideration given to aging-friendly design, among other aspects, to make the houses more in line with the living habits and needs of rural residents.

Component and Building Specifications

The "Appearance Quality Requirements and Dimensional Deviation Limits for Prefabricated Concrete Components for Prefabricated Buildings (Draft for Comment)" specifies the classification, general provisions, requirements, test methods, and inspection rules for prefabricated concrete components used in prefabricated buildings, applicable to production and inspection. The "Technical Specification for Prefabricated Concrete Structure Buildings (Draft for Comment)" is divided into 11 chapters and 2 appendices, covering general provisions, terms and symbols, basic requirements, integrated building design, and other aspects. It references international advanced standards and summarizes and incorporates mature experience from both domestic and international sources.
