Description
Technical field
The invention patent relates to historic building conservation technical field, especially a kind of measurement side of masonry ancient building weatherability
Method.
Background technique
Ancient building refers to civil buildings and public building with historic significance, they are the cultural interdependent of the whole mankind, goes through
The treasure that history carries over is the important carrier of various substances in historical rudiment, immaterial factor, recognizes us and goes through
History, the track for recognizing forefathers have incomparable important value, are exactly in contemporary society, in history, culture, art, science, ancestor
The tourism derived from fields and these fields such as religion, brand, economic aspect, which are all contained, outstanding to be generally worth.As city
The ancient building of city's a part, they are the solidifications in city, are the marking symbols that a city is different from other cities, are regions
The representative of culture, is the soul in city.In face of expanding economy, ancient building is used and is developed under the driving of economic interests,
Range constantly expands, and the sustainability use of ancient building suffers from stern challenge.The protection of ancient building in use is asked
Topic seems more prominent.
For masonry ancient building, under exposing to the weather year in year out, although short-term inner surface can't see its variation, in fact
Have occurred that weathering.Rate of decay is one of masonry ancient building stability, durability evaluation and important evidence of protection scheme,
It is not only to judge that weathering, the changed foundation of material properties occur for which part, while being also to determine weathering speed, determine
Rate of decay and the foundation for determining masonry ancient building reinforcement means and reinforcement depth.Masonry ancient building long-time weathering in order to prevent
After cause irreversible loss, to the weatherability of masonry ancient building carry out detection be particularly important.
There are mainly two types of for the existing measuring method to masonry ancient building body structure surface weatherability:
One, the direct method of measurement.Acicular iron staff is vertically pierced into masonry structure surface, then takes out iron staff, then use scale
The depth being pierced into is measured, depth value regards depth of weathering.However, the measurement method of this method subject, firmly etc. factors
It is affected, lacks objectivity；And hand dipping speed is slow, accuracy rate is low.
Two, the indirect method of measurement.The surface of mortar and brick is sprung back respectively using mortar reisilometer and brick reisilometer, is led to
Cross the numerical value conversion surface strength of rebound, indirect assessment rate of decay.However, working as the serious weathering of masonry ancient building body structure surface
When, existing reisilometer often fails to the masonry ancient building of the serious weathering in surface, rebound value can not be read, also just can not
To the rate of decay of masonry ancient building.
