Technical field
The present invention relates to the construction method and sun-dried mud brick of a kind of adobe wall suitable for highly seismic region of providing fortification against earthquakes, belong to building
Field of engineering technology.
Background technology
Sun-dried mud brick agriculture room is gathered materials on the spot, cheap, the extensive utilization in the poor rural area in western China.Sun-dried mud brick agriculture room
It is the important component in traditional characteristicses village, by taking province with rich ethnic culture Yunnan as an example, the traditional residence of its 26 Ge Shi resident race
All more or less using the raw-soil as construction material.From in terms of present circumstances, sun-dried mud brick agriculture room is just increasingly exiting the stage of agriculture residence construction,
Mainly there is three below reason：First, traditional sun-dried mud brick agriculture room anti-seismic performance is not good, and in all previous earthquake, adobe wall collapses and be all
Cause the one of the main reasons of casualties；Secondly, the main body load-carrying members of traditional adobe house use timber structure, adobe wall master
Play enclosure wall, timber price is high, be susceptible to fire, peasant is difficult to bear；Again, by traditional raw-soil building technology
Limitation, traditional immature soil dwelling windowing is small, indoor dark, it is difficult to meet the requirement that living quality is improved in rural area.Thus, it is necessary to pin
To the deficiency of traditional sun-dried mud brick wall technology, improved technology is proposed, for the succession and development of adobe house provide technical support.
There have been some antidetonation strengthening measures and structural system for adobe wall agriculture room, including cast-in-situs gypsum in the country at present
Sun-dried mud brick wall construction, plank sandwich structure, gallows timber-sun-dried mud brick wall construction etc..The more traditional adobe wall of shock resistance of these technologies has
It is certain to improve, but can't effectively solve the anti-seismic problem in highly seismic region sun-dried mud brick agriculture room.Timber is easily mouldy rotten rotten, and gypsum is not only
It is by resource constraint and not water-fast.
To solve the above problems, " the earth building blocks wall that a kind of armored concrete is strengthened "（The patent No.：
CN201020189029.6）Proposition reinforced concrete circle beam and column strengthen earth building blocks wall, it is characterised in that the wall base with
