Description
Technical field
The present invention relates to a kind of lattice single-row reinforced T section concrete column and the practice, belong to a kind of novel practical, cheap and be applicable to lattice single-row reinforced T section concrete column and the practice of village-town house.
Background technology
Earthquake is as a kind of unpredictable, natural calamity that destructive power is extremely strong, and all previous generation has brought huge loss all for the people's life and property.China is in the multiple phase of earthquake in recent years, and 17 secondary earthquake disasters only just occurred in 2006, Wenchuan earthquake wherein, and just nearly 6,451 hundred million yuan of the economic losses caused, dead and wounded number reaches more than 10 ten thousand.China's seismic region distribution simultaneously is wide, and the areas of fortification intensity more than 6 degree reach account for more than 60% of area, and mostly are in area, villages and small towns underdeveloped.Due to economic cause, these regional houses adopt the masonry load-carrying members mostly, and most of house do not adopt anti-seismic construction measure, and such masonry building belongs to friable structure, and anti-seismic performance is poor, very easily collapse while meeting with larger earthquake.Domestic anti-seismic technology research at present, mostly concentrate on high level, Super High and large-span structure aspect, less to earthquake resistance in rural area research, and all previous earthquake disaster is while occurring, losing the most heavy is exactly often vast area, villages and small towns, and Wenchuan earthquake and Yushu earthquake have just illustrated this point.
The main constructional materials of brick house is loam brick, and its main source is ploughed exactly.China ploughs and only deposits 1,600,000,000 mu, and per capita area of cultivated farmland is lower than 1/3 of world average level, and the speed that makes to plough with millions of mu of every year due to firing of loam brick reduces.Therefore, China, in the urgent need to carrying out the materials for wall innovation, thoroughly abolishes loam brick, replaces new structure and the material of safety, environmental protection, antidetonation.The shaped pile frame lightweight wall construction, be hidden into pillar in body of wall, effectively increased building area, improved the use function of building, and makes the aesthetic interior of residential structure smooth; Space enclosing structure is taked Light Wall, and dead load is alleviated, and geological process is little.Therefore, the shaped pile frame lightweight wall construction has become replacement brick mix structure important feature form, and current has been the energy-saving residence form of structure that China's emphasis is promoted.
Traditional shaped pile frame lightweight wall construction, multiplex in multilayer and little high residential building structure, the equal more complicated of technical scheme and job practices, construction costs are also higher, are not suitable for for the villages and small towns architectural structure system.Therefore, research economical rationality, the receptible shaped pile frame lightweight wall construction of masses system, solve the problems such as the rural house globality is poor, shock resistance is weak, thermal and insulating performance is poor, has important economy and society and be worth.
