Description

Odd-shaped cross section steel tube regeneration concrete-core column
Technical field
The present invention relates to a kind of concrete component, particularly relate to a kind of regeneration concrete odd-shaped cross section steel tube concrete core pillar for civil engineering, is a kind of novel concrete filled steel tube coupled column.
Background technology
At present, the frame column as the main member of frame construction, is generally common reinforced concrete post.But owing to cannot solving the thickness that is often greater than body of wall due to the sectional dimension of frame column, in use, the indoor pillar that there will be is partly given prominence to the phenomenon of body of wall, thereby has affected indoor space and use.
In order to address this problem, there is the form of structure of shaped rc columns.For reinforced concrete special-shape column structure, mainly contain T, L, cross, scholar both domestic and external has carried out extensive, deep research.Its theory basically forms, and writing of the local rules that the provinces and cities such as Tianjin, Shenyang, Guangdong, Shanxi have completed, and guides in engineering practice, and building area reaches number with ten million square metre.
But, also find under study for action: the ductility ratio ordinary rectangular post of shaped rc columns poor.Hetermorphiscal column is due to the existence of many limbs, and its centre of shear does not often overlap with the cross section centre of form, and under stress, each limb produces warped normal strain and shear stress.Due to shear stress, make post limb concrete occur crack prior to ordinary rectangular post, produce abdomen shear crack, cause hetermorphiscal column fragility obvious, the deformability of hetermorphiscal column is reduced than ordinary rectangular post.
In order to address this problem, many experts once proposed many suggestions and scheme.As I once applied for patent: steel pipe concrete profiled pile, special-shaped carbon fiber reinforced plastic steel tube concrete core pillar, a kind of steel reinforced high strength concrete column etc.Although these technology can address this problem to a certain extent, also not bery perfect, especially concrete materials, are unfavorable for environmental protection and energy-conservation.
Under present circumstances, waste concrete in the building waste that the whole nation removes from old building every year just has 1,360 ten thousand tons, add that annual newly constructed house produces the waste concrete that the building waste of 4,000 ten thousand tons produces, the environmental problem of its huge disposal cost and thus initiation is also very outstanding.In order to reduce to greatest extent the exploitation to natural resource, must increase to greatest extent construction refuse regenerated utilization.Therefore the processing of building waste and the research of application technology and application are imperative.Yet, at present due to the inherence damage of regeneration aggregate and due to its adsorption the water absorption rate that causes of the old mortar of one deck large, cause intensity, shrinkage and the endurance quality etc. of its regeneration concrete being made into poor compared with ordinary concrete, greatly limited its scope of application.In order to promote the utilization of regeneration concrete, by analyzing the achievement in research in early stage, invented a kind of odd-shaped cross section steel tube regeneration concrete-core column, can solve the deficiency of shaped rc columns, can utilize building waste again, discarded concrete is carried out to direct or indirect utilization again, the good method of can yet be regarded as.
Summary of the invention
The object of this invention is to provide a kind of odd-shaped cross section steel tube regeneration concrete-core column, make full use of waste and old concrete, accomplish twice laid, energy conservation, environmental protection are led to.
The present invention is achieved through the following technical solutions: odd-shaped cross section steel tube regeneration concrete-core column is comprised of round steel pipe, reinforcing bar and regeneration concrete, and form a whole by regeneration concrete, the section form of concrete-core column is T, L, cross, it is characterized in that: in the steel pipe of odd-shaped cross section steel tube regeneration concrete-core column, fill regeneration concrete or concrete, and steel pipe outside filling regeneration concrete, in concrete, contain the regeneration concrete fragment that serves as aggregate.
The regeneration concrete fragment that serves as aggregate in concrete, particle diameter at 5mm~30mm as the coarse aggregate in regeneration concrete.According to every cubic metre of regeneration concrete volume, coarse aggregate regeneration weight 200kg~1400kg, cement 400 kg~600 kg, water 150 kg~300 kg, the ratio of fine sand 150kg~1500kg fully stirs.
Advantage of the present invention and effect are:
1. make full use of discarded building waste, form regeneration concrete, accomplish twice laid, energy conservation, environmental protection;
2. steel pipe is positioned at the inside of direction concrete crossover sites in length and breadth, can be fire-resistant, corrosion-resistant;
3. can first pour into a mould the concrete of steel duct, the outer concrete of surveying of rear cast steel pipe, thus form superposed column;
4. due to the existence of steel pipe, improve the ductility of post, improved the bearing capacity of post, be beneficial to earthquake zone seismic design.
