Description
Technical field
Technical field of civil engineering of the present invention, and in particular to construction refuse regenerated monolith as packing material
Construction refuse regenerated concrete superposed column.
Background technology
The useless commerical ready-mixed concrete amount that Building Trade in China removes discharge after rebuilding is huge, not only brings serious environment and society
Meeting problem, occupies the land resource of growing tension in urban construction, also increases the production cost of building products.In face of increasingly
Severe environments pollution, the land supply being becoming tight day and increasingly exhaust mineral resources the problems such as, carry out building waste synthesis
Using very urgent.Discarded concrete in building waste is manufactured the structure in building structure after broken as regenerated aggregate
Part, can solve the problems, such as that natural aggregate resource is nervous, realize the regeneration of concrete and recycle, and realize sustainable development
Exhibition.
The construction development of current domestic city high-rise building is swift and violent, and precast construction has been widely used for high-rise building knot
In structure.Recycled concrete superposed column involved in the present invention combines conventional concrete technology maturation and China's building waste amount
The big advantage of the two, with low cost, construction is simple, and the duration is shorter, is conducive to preferably preserving the ecological environment, and beautifies the environment
Many merits.The superposed column sets steel reinforcement cage, preferably improves overall performance, stress performance and the workability of post, has
Low cost, construction is simple, and the duration is shorter, and many merits such as be conducive to preferably preserving the ecological environment.And the present invention is pre- using part
The cast-in-place thought in part processed, is suitable for different project situation demands, makes its mechanical property and globality no less than even more than biography
System concrete column.
The content of the invention
To provide energy-conserving and environment-protective, overall performance is good, and construction refuse regenerated concrete superposed column overcomes above-mentioned existing skill
Art shortcoming.The present invention provides construction refuse regenerated concrete superposed column and preparation method.Cylinder uses material and regeneration concrete
Material, using half cast-in-place half prefabricated construction technology, with convenient, function admirable of constructing, it is with low cost the characteristics of.
In order to solve the above problems and realizing above-mentioned requirements, the present invention takes following technical solution：One kind building
Garbage regeneration concrete superposed column, it is characterised in that by regenerated aggregate concrete precast hollow post, be filled in regeneration aggregate coagulation
The cast-in-place regeneration monolith of the center cavity of native precast hollow post, along column length direction set it is pre- in regenerated aggregate concrete
Steel reinforcement cage B compositions on the inside of open tubular column processed, the length and width of regenerated aggregate concrete precast hollow post and foundation practice of construction requirement high
The appropriate size of selection.
Regenerated aggregate concrete precast hollow post cavity inside diameter d is more than 50cm, regenerated aggregate concrete precast hollow post
Skeleton is that steel pipe or FRP are managed, while disposing steel reinforcement cage A in open tubular column.
It is close to the steel reinforcement cage B of inwall setting along regenerated aggregate concrete precast hollow post column length direction；Steel reinforcement cage B is close to sky
Stem inwall.
It is filled in the cast-in-place regeneration monolith and new coagulation of the center cavity of regenerated aggregate concrete precast hollow post
The weight ratio of soil is 2:1-4:Between 1.
5th, a kind of construction technology of construction refuse regenerated concrete superposed column, it is characterised in that step is as follows：
（1）In producting factory, with the material use rubber such as steel pipe or FRP pipes, regenerated aggregate concrete, the steel reinforcement cage 1 of suitable dimension
Regenerated aggregate concrete precast hollow post is made in glue core, steel reinforcement cage 2 is placed along inwall in open tubular column, and in advance
It is pre-buried to lift crotch well；
（2）Transport puts point location to job site, and regenerated aggregate concrete precast hollow post is installed using crotch is lifted；
（3）Waste and old concrete block will fully be watered in advance wetting, by regeneration monolith and novel concrete weight when pouring
Amount compares 2:1-4:1 delivers, and fully vibrates, is compacted.Regeneration monolith used by block be old buildings, structures, road,
Bridge or dykes and dams remove and remove protective layer and all or part of reinforcing bar after waste and old concrete block.Regeneration monolith
The size of block used should be chosen according to actual design requirement, unsuitable excessive or too small.Poured using novel concrete between block,
Ensure the globality of structure；
（4）After details adjustment is finished, one-piece casting beam, plate part.
Post selects steel pipe or FRP tube materials, the length and width of regenerated aggregate concrete precast hollow post and foundation practice of construction high
It is required that the appropriate size of selection, the skeleton of regenerated aggregate concrete precast hollow post is that steel pipe or FRP are managed, while hollow
Steel reinforcement cage A is disposed in post to strengthen column intensity.
Novelty of the invention：1. suitable for steel pipe or the mixed structure of FRP pipes and concrete, regeneration block is mixed the present invention
Solidifying prefabricated core column factorial praluction, intensity is high, corrosion-resistant, excellent in durability, and it is convenient to construct.2. prefabricated along regenerated aggregate concrete
Steel reinforcement cage 2 is set in open tubular column, when regeneration monolith is poured, regenerated aggregate concrete precast hollow post can be increased and mixed
Solidifying Soil Interface cohesive force, significantly improves ultimate bearing capacity, deformability and the ductility of component, effectively prevent precast hollow post with
Concrete interface comes to nothing, and improves effect of contraction of the regenerated aggregate concrete precast hollow post to core concrete, Ke Yibao
Hold more preferable stability, it is ensured that the intensity of structure.3. construction refuse regenerated concrete is selected, compared to normal concrete, with green
Color, energy-conservation, high-strength light and durability are good, cost-effective advantage.4th, it is cast-in-place in again using monolith material is regenerated
The concrete prefabricated open tubular column cavity of raw aggregate, enormously simplify broken, screening, purification when waste and old concrete is recycled etc.
Reason process, saves a large amount of manpowers, time and the energy, and the efficient circulation for being capable of achieving building waste is utilized.In addition, from block
Body concrete, it is possible to achieve the globality of well-formed.Greatly improve the intensity of the cylinder.5. what patent of the present invention was used is prefabricated
Mounting technology is compared with traditional handicraft, simplifies construction technology and difficulty of construction, can be given full play to and effectively be lifted conventional post
The significant advantage of the aspects such as stress performance, endurance quality, fire resistance and economic performance, is widely portable to large span, heavy burden
Carry or complicated, irregular skyscraper and high-rise building.
