Shandong Prefabricated Assembly-type Housing
Shandong prefabricated assembly-type housing refers to rural residential houses that are prefabricated or partially prefabricated with components in factories and then assembled on construction sites. Their construction adheres to principles such as modern functionality and structural safety, with clear technical guidelines, prevention and control measures, as well as the promotion of development through relevant enterprises and projects.
Technical Guidelines
The "Technical Guidelines for the Construction of Prefabricated Rural Houses in Shandong Province" came into effect on July 1st, clearly defining its scope. In terms of structural systems, there are various systems such as prefabricated concrete shear wall structures, along with detailed design and construction specifications. Regarding materials, it emphasizes adapting to local conditions and using locally sourced materials, prioritizing green and economical building materials while prohibiting high-energy-consuming and excessively polluting materials. In design, it respects the needs of farmers, reflects regional characteristics, considers aging-friendly design, and合理安排朝向 (reasonably arranges the orientation). In construction, it is advisable to have professional teams or trained craftsmen carry out the work, with the preparation of construction organization plans and schemes.
Engineering Quality Prevention and Control Measures
Strictly implement the factory supervision and initial segment acceptance system for prefabricated components, marking them with unique codes upon leaving the factory and providing quality certification documents. The adoption of new structural systems requires expert论证 (demonstration) at the provincial level or above. Utilize BIM technology for integrated forward design, conduct special design briefings and drawing reviews before the start of construction, and ensure that secondary detailed designs are approved and reviewed. Different prefabricated components have varying inspection requirements upon arrival at the site. Before installation, check the connecting reinforcement. Grouting construction has strict inspection and testing requirements, with continuous and full grouting at vertical connection points and the retention of image data. For grouting installation in connected cavities, there are requirements for sealing and spacing.
Relevant Enterprises and Projects
Shandong Chengkai Yuanda Prefabricated Construction Co., Ltd. was established in February 2018 and has participated in the signing of several prefabricated rural housing projects, with multiple projects adopting its technology. "Penglai Prefabricated" is a regional brand, with Penglai District being awarded the title of "Provincial Prefabricated Building Demonstration City." Some enterprises have been recognized as national prefabricated building industry bases, and relevant methods and opinions have been issued to promote development.
