Description
Technical field
The present invention relates to a kind of confined masonry structure and preparation method thereof, belong to a kind of novel masonry structure and preparation method thereof.
Background technology
Along with developing rapidly of China's rural economy, the villages and small towns construction has started the another new upsurge of taking turns after last century the mid-80.But see through the fiery scene of present villages and small towns construction, be not difficult to find out that the villages and small towns construction project in many places also exists problems such as hidden danger of quality is many, house weak point in application life, quality accident happens occasionally.Through investigation, in present villages and small towns building, collar tie beam and constructional column are not set basically, even have, the sectional dimension arrangement of reinforcement does not all have basis, randomness is very big, does not have the actual effect that should reach.Floor adopts precast plate mostly, and precast plate directly is shelved on the body of wall during no collar tie beam, gos deep into the less than normal of body of wall, causes the globality in house relatively poor.Therefore, in all previous earthquake, the villages and small towns building is often disaster-stricken the most serious.
Clear and definite regulation has been made in setting to masonry structure collar tie beam, constructional column in existing " seismic design provision in building code ".Be subjected to the limitation of economic development situation, it is unpractical claiming to house, China villages and small towns according to " seismic design provision in building code " fully.Therefore, research economical rationality, the receptible technical measures of the masses, it is poor to solve house, villages and small towns globality, and problem weak in the antidetonation energy is also extremely urgent.
Summary of the invention
