Foreword

According to the requirements of the Ministry of Housing and Urban-Rural Development's Notice on Printing and Distributing the <2008 Project Construction Standards and Specifications Development and Revision Plan> (First Batch) (Jianbiao [2008] No. 102), the code preparation team has conducted extensive investigations and studies carefully. Summarize practical experience, refer to relevant international standards and advanced foreign standards, and revise this procedure on the basis of extensive consultation.
The main technical contents of this regulation are: 1. General provisions; 2. Terminology; 3. 3. Construction foundation engineering; 4. 4. Masonry works; Reinforcement engineering; 6. Concrete engineering; 7. 8. Thermal insulation and roof waterproofing works; 8. 9. Building decoration works; 10. Steel structure engineering; 11. Concrete component installation works; Overwintering project maintenance.
The main technical contents of the revision of this regulation are:
1. Merged the two chapters "Earthwork" and "Foundation and Foundation Engineering" and renamed it "Building Foundation Engineering";
2. Increase the technical content of winter construction of foundation pit support;
3. Chapter "Masonry Engineering" was renamed "Masonry Engineering";
4. Cancel the freezing method construction in the original "masonry project";
5. Cancel the negative temperature cold drawing of steel bars and increase the winter construction regulations for electroslag pressure welding of steel bars;
6. Amend the regulations on the critical strength of concrete under freezing temperature;
7. Cancel the discriminative formula for concrete comprehensive heat storage method;
8. Chapter "Roof Insulation and Waterproofing Engineering" was renamed to "Heat Insulation and Waterproofing Engineering" to increase the content of winter construction of external wall insulation engineering;
9. "Decoration Project" was renamed "Building Decoration and Decoration Project" and the winter construction content of the finishing project was cancelled;
10. Revised the original Appendix A “Calculation of Soil Insulation and Freezing Prevention”;
11. Revised the original Appendix B "Thermal Calculation of Concrete" formula;
12. Removed the original Appendix C "Concrete strength growth laws of concrete at various ages under negative temperature";
13. Revised the original Appendix D "Calculating Early Strength of Concrete by Maturity Method".
This Regulation is managed by the Ministry of Housing and Urban-Rural Development, and the Heilongjiang Institute of Architectural Cold Science is responsible for the interpretation of specific technical content.
