How to reinforce the ancient buildings?

Ancient buildings are valuable historical and cultural heritage of mankind, with high historical value, artistic value and scientific value. But after years of wear and tear, all appear different damage. Some are even on the verge of destruction, so the reinforcement and maintenance of ancient buildings is crucial.

The basic principle of ancient building protection is to maintain the original or current situation, avoiding as little intervention as possible, in line with the principle of the intrinsic requirements of all objects and the principle of reversibility of protective materials.

China's ancient architect Mr. Liang Sicheng for the refurbishment of ancient buildings put forward "repair the old as the old" point of view, this point of view, has been used as a platform for the maintenance of ancient buildings.

Cultural heritage principles of ancient building repair should be unified with the original seismic reinforcement of ancient buildings, in the repair of ancient buildings at the same time can also achieve the effect of seismic reinforcement, so that the repair and seismic reinforcement integration.

To do "repair the old as the old". It is necessary to do the following:

1, the principle of less intervention. We have to repair an ancient building. Because it has some aspects of the danger, such as foundation, structure, or materials. To repair, it is inevitable to reinforce the foundation, enhance the structure, replace the material.

These measures are all will produce changes in the ancient building itself, quantitative to qualitative changes. Move the more, "repair the old as the old" is more difficult to maintain, it is obvious. Therefore, in order to "old", we must less intervention, this is a vital one.

2, try to save the original ancient materials. Cultural relics and monuments of the material is the carrier of historical information, is thousands of years of history and modern people as well as the medium of communication with future people, you can read from a Han brick in the Han Dynasty brick clay, billet-making process, firing methods, as well as the Han Dynasty, the craft of this building material modification.

3, inheritance and use of traditional crafts. Ancient architecture is the ancient craftsmen in accordance with its then local production level, craft means and aesthetic point of view made. Therefore, it has a strong period and locality. "Repair the old as the old", we must use traditional crafts to restore it.

The methods of reinforcing the wooden structure of ancient buildings include: trimming and reinforcing, vibration isolation technology, chemical anchoring, supporting the top of the reinforcing, embedded reinforcement and so on.

The methods of masonry structure ancient building reinforcement are: seismic reinforcement, external steel reinforcement, replacement of components method, reinforced cement mortar reinforcement, grouting reinforcement, static pile and so on.

The existing norms and standards for the reinforcement of ancient buildings to organize, modify, in accordance with the different characteristics of different ancient buildings, in-depth study of ancient building restoration and reinforcement, so as to better maintain the safety of the ancient buildings, the inheritance of generations.
