Description
Technical field
The invention belongs to technical field of civil engineering is and in particular to construction refuse regenerated concrete is as the material of filling
Concrete filled steel tube column preparation method.
Technical background
Among municipal refuse, building waste accounts for the 30%～40% of rubbish total amount.In future, with urban construction from extensional mode
Develop the extensive reconstruction of the old city town with connotative to develop simultaneously, China's building waste yield will sustainable growth.In the face of increasingly serious
Land supply that environmental pollution, day are becoming tight and day by day exhaust mineral resources the problems such as, the building waste of enormous amount certainly will
People, environment, the contradiction situation between resource, the coordinated development of impact urban ecological environment can be aggravated, carry out the comprehensive of building waste
Close using very urgent.
According to statistics, the annual building waste producing of China, only discarded concrete total amount just reaches more than 120,000,000 tons.To build
Manufacture the component in building structure after discarded concrete in building refuse is broken as regenerated aggregate, natural aggregate money can be solved
The nervous problem in source, realizes the regeneration of concrete and recycles it is achieved that sustainable development.
The construction development of domestic city high-rise building is swift and violent at present, and concrete filled steel tube is as a kind of emerging combination knot
Structure, has been widely used in super-high building structure.Mainly based on the compression member of axial compression and active force small eccentricity,
It is widely used in frame structure (as Factory Building and high level).Steel tube regeneration concrete combination column involved in the present invention combines
Conventional steel concrete technology maturity and the big advantage of the two of China's building waste amount, are fabricated to carry on tube wall and put more energy into
The coupled column of rib, preferably improves overall performance, stress performance and the workability of steel pipe column, has low cost, construction letter
Single, the duration is shorter, and the many merits such as be conducive to preferably preserving the ecological environment.
Content of the invention
For solving above-mentioned technical problem, the invention provides a kind of energy-conserving and environment-protective, overall performance is good, and intensity is very high
Steel pipe half cast-in-place construction refuse regenerated concrete combination column prefabricated with half.By steel pipe and regeneration monolith prefabricated core column with
And cast-in-place regenerated aggregate concrete composition, use construction refuse regenerated aggregate between steel pipe and regeneration monolith prefabricated core column
Concreting, thus prepare a kind of steel pipe and half prefabricated half cast-in-place construction refuse regenerated concrete combination column.
In order to solve the above problems and realize above-mentioned requirements, the present invention takes following technical solution：A kind of steel pipe
Half cast-in-place construction refuse regenerated concrete combination column prefabricated with half, including steel pipe, regeneration monolith prefabricated core column and steel pipe
Interlayer and regeneration monolith prefabricated core column between.
1st, steel pipe selected by spinous process of the seventh cervical vertebra frame.The length and width of steel tube body and the high size suitable according to practice of construction requirement selection；Internal
The length and width of regeneration monolith prefabricated core column and high require to select suitable size according to practice of construction.
2nd, steel pipe upper band ribbed stiffener at regular intervals.Ribbed stiffener is uniformly distributed around pipe direction, spacing 10cm, vertical direction
Interval 15cm.
3rd, the prismoid groove of deep 30cm in is opened on regeneration monolith prefabricated core column top, and prismoid groove pushes up
Face is the square of length of side 20cm, and bottom surface is the square of length of side 15cm, regenerates monolith prefabricated core column bottom simultaneously
The square being a high 25cm is raised, and the square length of side is 10cm, and upper prop section can be made raised upper and lower with hypomere post section groove
It is mutually butted, cement mortar is closed admittedly in junction, formed overall.
4th, the interlayer between steel pipe and regeneration monolith prefabricated core column is poured using regenerated aggregate concrete.
5th, regenerate the construction technology of monolith prefabricated core column：Make forming panel in the way of keeping flat, and pre- in advance
Bury lifting crotch, in advance waste and old concrete block is fully poured water-wet.When pouring, throw in pre-wetting in forming panel
Waste and old concrete block, add novel concrete, the weight of regeneration monolith and novel concrete ratio is 2:1-4:Between 1
Optimum.Block used by regeneration monolith is that old buildings, structures, road, bridge or dykes and dams are removed and removed protection
Waste and old concrete block after layer and all or part of reinforcing bar.Used by regeneration monolith, the size of block should be according to reality
Design requirement is chosen, unsuitable excessive or too small.Pour the globality it is ensured that structure using novel concrete between block.
Advantages of the present invention：
1. the present invention is applied to the mixed structure of steel and concrete, regenerates block coagulation prefabricated core column factorial praluction, intensity
High, corrosion-resistant, excellent in durability, construction is convenient.
2nd, carry the design of the steel pipe of ribbed stiffener with surface, pouring regenerated aggregate concrete, steel pipe and coagulation can be increased
Soil Interface cohesive force, significantly improves ultimate bearing capacity, deformability and the ductility of component, effectively prevents steel pipe and coagulation pedosphere
Emaciated face is empty, and improves the effect of contraction to core concrete for the steel pipe, more preferable stability can be kept it is ensured that structure strong
Degree.
3rd, select construction refuse regenerated concrete, instead of normal concrete, green, energy-conservation, high-strength light and durability
Well, greatly reduce cost simultaneously.
4. the groove of regeneration monolith prefabricated core column upper and lower ends and bulge-structure, can interconnect, Ke Yiguang
General apply in skyscraper, make construction work facilitation, sequencing.
5th, do prefabricated core column using regeneration monolith, enormously simplify when waste and old concrete recycles broken,
The processing procedures such as screening, purification, save a large amount of manpowers, time and the energy, and the efficient circulation of achievable building waste utilizes.Remove
Outside this, from monolith, it is possible to achieve the globality of well-formed.Greatly improve the intensity of this cylinder.
