Abstract
The invention discloses a latticed single-row reinforced Z-shaped sectional concrete column and a making method, and belongs to the field of shock absorption and disaster prevention. The concrete column consists of concrete 1, step grid-like common reinforcing meshes 2, latticed single-row reinforced nets 3 and steel ties 4; a reinforcement framework of the Z-shaped column is Z-shaped, and three latticed single-row reinforced nets 3 are welded to form two Z-shaped limbs; the step grid-like common reinforcing meshes 2 are vertically welded at the ends of the two limbs of the Z-shaped latticed single-row reinforced nets; and the steel ties 4 are vertically welded in the centers of transverse horizontal steel bars of the common reinforcing meshes 2. By adopting single-row reinforcement, the concrete column is simple in construction and low in consumption of steel bars; the reinforcement is formed by welded latticed reinforcement sheets, so that the concrete column is suitable for industrialized production; by adopting latticed reinforcement, oblique web ribs have good shearing resistance, crisp shearing damage of the special-shaped sectional short column can be prevented, and the anti-earthquake ductility is improved; the ends of the section of the column are tightly combined with ecological wallboards or ecological wall bricks by using short steel bars, so that the aims of reinforcing the integrity of a house and promoting the integral anti-earthquake and energy dissipation capacity are fulfilled, and the concrete column is suitable for a rural house.
Description
Technical field
The present invention relates to a kind of lattice single-row reinforcement Z-section concrete column and the practice, belong to a kind of novel practical, cheap and be applicable to the lattice single-row reinforcement Z-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 tremendous 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 took place in 2006, Wenchuan earthquake wherein, and just nearly 6,451 hundred million yuan of the economic losses that causes are surplus dead and wounded number reaches ten ten thousand.China's seismic region distribution simultaneously is wide, and the area of fortification intensity more than 6 degree reach accounts for more than 60% of area, and is in area, villages and small towns underdeveloped mostly.Because 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 relatively poor, very easily collapses when meeting with larger earthquake.Domestic anti-seismic technology research at present; Concentrate on high level, superelevation layer and large-span structure aspect mostly, less to the villages and small towns earthquake research, and all previous earthquake disaster is when taking place; What loss was the most heavy often is exactly vast area, villages and small towns, and this point has just been explained in Wenchuan earthquake and cajaput earthquake.
The main constructional materials of brick house is a 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 because firing of loam brick makes the speed minimizing of arable land with millions of mu of every year.Therefore, China presses for and carries out the materials for wall innovation, thoroughly abolishes loam brick, replaces the new structure and the material of safety, environmental protection, antidetonation.The shaped pile frame lightweight wall construction is hidden into pillar in the body of wall, has effectively increased building area, has improved the function of use of building, and makes the aesthetic interior of residential structure smooth; Space enclosing structure is taked the lightweight body of 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 structure 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 is used for multilayer and little high residential building structure more, and the equal more complicated of technical scheme and job practices, construction costs are also higher, are not suitable in the architectural structure system of villages and small towns.Therefore, research economical rationality, the receptible shaped pile frame lightweight wall construction of masses system solve problems such as house, villages and small towns globality is poor, shock resistance weakness, thermal and insulating performance difference, have important economy and society and are worth.
Summary of the invention
The object of the present invention is to provide a kind of lattice single-row reinforcement Z-section concrete column and practice, problems such as house, villages and small towns globality is poor in the hope of solving, shock resistance weakness, thermal and insulating performance difference with advantages such as simple structure, cheap, easy construction, anti-seismic performance are good.
