Introduction
1. Background of Standard Formulation
This standard revision is based on the requirements of the Ministry of Housing and Urban-Rural Development, combined with years of practical experience and international advanced standards, to systematically regulate the protection and maintenance of wooden structures of ancient buildings.
2. Comparison of standard frameworks
| Chapters | Contents of the new standard | Differences from the old standard |
|---|---|---|
| Terms | 16 new professional term definitions, such as 'damaged points' and 'repair and reinforcement' | The old standard did not systematically define the relevant terms |
| Project monitoring | Added temperature and humidity monitoring requirements and vibration impact assessment | The old standard had no relevant monitoring regulations |
| Safety assessment | New requirements for component bearing capacity verification and seismic assessment | The old standard only involved general assessment |
3. Implementation suggestions and precautions
Implementation focus: In the process of implementing the standard, special attention should be paid to the following points:
- Strictly follow the 'minimum intervention principle' to avoid excessive repairs that affect the original appearance of ancient buildings.
- When selecting wood, ensure that its moisture content is close to the local equilibrium value and make identifiable marks.
- Regularly monitor structural deformation and temperature and humidity changes to promptly identify and deal with potential problems.
