Description
Technical field
The present invention relates to building castoff regenerative use technology fields, more particularly, to one kind wait tear reinforced concrete in structure open
The regeneration method of native beam column Component- Based Development level.
Background technique
With China's economic development, old building is constantly removed, and new building is largely built, and appearance of city shines right one
Newly, but simultaneously serious environmental problem is also brought：One side new building consumes large number of cement and sandstone etc. and builds
Material is built, new building is on the other hand built and dismounting Old building produces a large amount of building waste again.China in 2010 according to statistics
Building waste is about 800,000,000 tons in bulk solid waste.Building waste overwhelming majority in China's is transported to countryside or rural area dew at present
It is stacked or landfill disposal, occupies a large amount of arable lands, while new building and a large amount of exploitation natural sand stones, serious to destroy nature ring
Border.
Building castoff regeneration is one after another studied in countries in the world, and one of importance is exactly mixed to regeneration
Coagulate the research of soil.Recycled concrete is that discarded concrete after broken, cleaning, classification, is formed recycled aggregate, portion
Divide or all instead of natural aggregate again mixing at the technology of novel concrete.
But since regeneration concrete structure to the regeneration of concrete is needed original is mixed based on material level
Xtah Crude Clay structure such as is crushed, is transported, being poured at the processes, greatly limits the application of regeneration concrete structure.
Summary of the invention
Being designed to provide for the embodiment of the present invention is a kind of wait tear reinforced concrete beam column Component- Based Development level in structure open
Regeneration method.
In order to solve the above technical problems, technical solution provided by the invention is：
Wait tear the regeneration method of reinforced concrete beam column Component- Based Development level in structure open, include the following steps：
1) it will be cut in structure wait tear reinforced column in structure and reinforced beam open from wait tear open in building
It cuts off, then hangs down；
2) reinforced column and reinforced beam under hanging to step 1) carry out reinforcing steel implant processing；
3) resulting exposed steel bar after reinforced column bar planting described in step 2) and the reinforced beam are planted
Resulting exposed steel bar binding is at existing at the connecting node for the reinforced column and the reinforced beam after muscle
The steel reinforcement cage of pouring concrete；
4) formwork casting concrete is carried out to the steel reinforcement cage made from step 3), it is mixed that the reinforcing bar is made after the completion of maintenance
The cast-in-place connecting node of solidifying earth pillar and the reinforced beam so far obtains armored concrete regeneration beam column.
Preferably, in step 1), the intensity of the concrete in reinforced column and reinforced beam cut down
For C20~C50, the yield strength of the reinforcing bar in reinforced column and reinforced beam cut down is 235N/mm2~
500N/mm2。
Preferably, in step 1), the cross section of the reinforced column and reinforced beam that cut down is rectangle, circle
Shape or odd-shaped cross section.
The regeneration method that this application provides a kind of wait tear reinforced concrete beam column Component- Based Development level in structure open, will
One whole reinforced column, the one whole reinforcing bar that has used certain time limit but still can continue to use with enough performances mix
It coagulates a certain section in earth pillar or a few sections in one whole reinforced column is directly cut down on building from wait tear open, will make
One whole reinforced beam, the one whole reinforced concrete that can be continued to use with certain time limit but still with enough performances
A certain section in native beam or a few sections in one whole reinforced beam are directly cut down on building from wait tear open, are then existed
Bar planting on the reinforced column and reinforced beam cut down, then again by reinforced column and reinforced beam
Resulting exposed steel bar binding is at the steel reinforcement cage for cast-in-place concrete at beam-column connection after bar planting, and then formwork pours mixed
Solidifying soil is made the cast-in-place connecting node of reinforced column and reinforced beam, so far obtains reinforced concrete after the completion of maintenance
Soil regeneration beam column；To take full advantage of wait tear the available component in structure open, reduce building waste, energy saving, green ring
It protects；The regeneration mode that novel reinforced concrete is formd from component level avoids regeneration concrete and is based on material level
Aggregate is first ground into carry out the complicated procedures of forming such as pouring again；By beam column cast-in-place concrete node, armored concrete regeneration is improved
Bearing capacity, anti-seismic performance and the stress performance of beam column.
Specific embodiment
For a further understanding of the present invention, the preferred embodiment of the invention is described below with reference to embodiment, still
It should be appreciated that these descriptions only further illustrate feature and advantage of the invention, rather than to the limit of the claims in the present invention
System.
The regeneration method that this application provides a kind of wait tear reinforced concrete beam column Component- Based Development level in structure open, packet
