Abstract
The invention discloses a stirrup-densified splicing joint for fabricated reinforced concrete columns. Densifying column end stirrups, embedded corrugated casing pipes and high-strength reinforcing steel bars are adopted for connection. The stirrup-densified splicing joint mainly comprises the upper reinforced concrete column, the lower reinforced concrete column, the corrugated casing pipes, the embedded high-strength reinforcing steel bars and the densifying stirrups. Embedment of the high-strength reinforcing steel bars is achieved through the method that non-shrinkage self-compaction high-strength concrete is poured into the embedded corrugated casing pipes on the upper reinforced concrete column and then the high-strength reinforcing steel bars are inserted, the corrugated casing pipes are reserved in the lower reinforced concrete column, and meanwhile stirrup densifying is conducted on the ends of the reinforced concrete columns. On the construction site, the upper reinforced concrete column and the lower reinforced concrete column are spliced through the method that grouting is conducted on the reserved corrugated casing pipes of the lower column and the embedded reinforcing steel bars of the upper column are inserted in the corrugated casting pipes of the lower column. On-site assembly connection is adopted for all the components which are used, the on-site welding work and formwork engineering are reduced, the building industrialization assembly efficiency is improved, and the novel architectural concept that the building components are energy-saving and environment-friendly is embodied.
Description
Technical field
The invention belongs to engineering structure technical field, it is particularly applicable to armored concrete in many high level assembled arthitecutral structures
Splicing field of operation in scene between post and post.
Background technology
The cast-in-place existing mode of construction built of tradition needs substantial amounts of template, scaffold, situ wet operation, timber, steel, cement

A person of good sense is had made intensive studies with post splicing method of attachment to reinforced column, then has this case to produce.
Content of the invention
The invention provides a kind of simple structure, install convenient efficiently, the assembled steel reinforced concrete column of energy-conserving and environment-protective with
The splicing node of post.
The present invention is achieved by the following technical solutions：
The invention provides it is a kind of assembled steel reinforced mixed using encryption styletable stirrup, pre-buried corrugated bushing and high tensile reinforcement
The splicing node of solidifying earth pillar and post, structural system main member include pre-buried high tensile reinforcement, corrugated bushing, on armored concrete
Post, armored concrete lower prop and encryption stirrup.It is characterized in that indulge in armored concrete upper prop down cross-sectional passing through in the range of muscle
The pre-buried high tensile reinforcement of corrugated bushing, and pre-buried corrugated bushing is with preformed hole in the range of the vertical muscle of armored concrete lower prop cross section
Hole, scene pour into mortar in the pre-buried corrugated bushing of lower prop after, by pre-buried for upper prop high tensile reinforcement insert lower prop corrugated bushing in
Realize splicing.Meanwhile, upper lower prop styletable stirrup is suitably encrypted, and stirrup spacing and intensity meet《The Concrete Structure Design is advised
Model》(GB50010-2010) specification and detailing requiments.
Further, pre-buried high tensile reinforcement and corrugated bushing should be arranged on upper lower prop same position indulge identical in the range of muscle
Position, to ensure that indulging muscle up and down does not misplace, and is easy to scene grouting insertion.
Further, in order to the shear-carrying capacity ensureing high tensile reinforcement can play one's part to the full, perpendicular to mast axis side
To the spacing of pre-buried corrugated bushing should meet related specifications and detailing requiments.
Further, pour into ungauged regions self-compacting high-strength concrete in the pre-buried corrugated bushing of armored concrete lower prop,
Pre-buried for upper prop high tensile reinforcement is inserted in lower prop corrugated bushing.Described ungauged regions self-compacting high-strength concrete, its strength grade is not
Strength grade of concrete less than prefabricated reinforced concrete column.
Further, the connecting portion in armored concrete upper prop and lower prop carries out blocking slip casting, realizes upper prop and lower prop
Entirety splicing.
Described assembled steel reinforced concrete column is fast with the achievable construction speed of the splicing node of post, the recyclable profit of construction material
Function.
Compared with prior art, the invention has the beneficial effects as follows：
1st, the present invention realizes the splicing of reinforced column and post, styletable stirrup using pre-buried corrugated bushing and high tensile reinforcement
Encrypted.The local concrete that act as of stirrup encryption is strengthened, is constrained corrugated bushing and the anti-bending strength of enhancing post.
2nd, all components all complete in factory process, transport to construction site, can assembly connection at the construction field (site), reduce
Site Welding work and shuttering work it is ensured that site operation quality, improve building industrialization efficiency of assembling.
3rd, the present invention mainly encrypts prefabricated reinforced concrete column by carrying out stirrup in splicing column styletable, and scene is passed through
It is in the milk in armored concrete lower prop corrugated bushing, then pre-buried for armored concrete upper prop high tensile reinforcement is inserted into armored concrete
In the corrugated bushing of lower prop, carry out blocking slip casting in armored concrete upper prop and lower prop coupling part, make armored concrete upper prop
With common stress after lower prop one entirety of formation so as to energy dissipation capacity and ductility are more superior, even if repairing after rarely occurred earthquake
Also can be less with changing cost.
