Technical solution on the assembled steel tube constraint only column squat pier of armored concrete.
To realize the present invention purpose and the technical solution adopted is that such, a kind of assembled solid steel tube constraint reinforcing bar mixes
Solidifying earth pillar squat pier, including the concrete column being prefabricated in the factory and the foundation of site operation.
The concrete column outside steel pipe.The lower surface of the concrete column has pier bottom groove and grout sleeve.
When the pier bottom groove is precast concrete column, in the centre bore that concrete column lower surface center is formed.Institute
It states before grout sleeve formed, a ring around pier bottom groove need to be reserved in concrete column lower surface in precast concrete column
Connected in star.
The outer surface of the steel pipe has several holes.The outer surface of these holes connection steel pipe and annular groove.
The foundation is by concreting, internal pre-buried several longitudinal reinforcements and shaped steel shear key.These longitudinal directions
The upper surface of foundation is exposed in the upper end of reinforcing bar, and surrounds a border circular areas.Also expose the upper end of the shaped steel shear key
The upper surface of foundation, and the center in the border circular areas.
At least one grout lines are reserved in the foundation.
When the concrete column is lifted into the foundation top, the lower end of the steel pipe and the foundation
Upper surface contact.There is gap between the upper surface of the concrete column and the foundation.The longitudinal reinforcement it is upper
End is stretched into the annular groove.The upper end of the shaped steel shear key is stretched into pier bottom groove.One end of the grout lines
Nozzle is covered by concrete column, other end nozzle is not covered by concrete column.
Grouting material is poured by the space of the hole and/or grout lines between concrete column and foundation.
The grouting material is filled in annular groove, forms grout sleeve.
Another embodiment is：
A kind of assembled solid steel tube constrains reinforced column squat pier, it is characterised in that:It is mixed including what is be prefabricated in the factory
The foundation of solidifying earth pillar and site operation.
The concrete column outside steel pipe.The lower surface of the concrete column has pier bottom groove and grout sleeve.
When the pier bottom groove is precast concrete column, in the centre bore that concrete column lower surface center is formed.Institute
It states before grout sleeve formed, a ring around pier bottom groove need to be reserved in concrete column lower surface in precast concrete column
Connected in star.
The outer surface of the steel pipe has several holes.The outer surface of these holes connection steel pipe and annular groove.
The foundation is by concreting, internal pre-buried several longitudinal reinforcements.The upper end dew of these longitudinal reinforcements
Go out the upper surface of foundation, and surround a border circular areas.The center of the border circular areas has basic groove.
At least one grout lines are reserved in the foundation.
When the concrete column is lifted into the foundation top, the lower end of the steel pipe and the foundation
Upper surface contact.There is gap between the upper surface of the concrete column and the foundation.The longitudinal reinforcement it is upper
End is stretched into the annular groove.The basis groove is docked with pier bottom groove.One end nozzle of the grout lines is mixed
Solidifying earth pillar covering, other end nozzle are not covered by concrete column.
Grouting material is poured by the space of the hole and/or grout lines between concrete column and foundation.
The grouting material is filled in annular groove, forms grout sleeve.
Further, steel pipe is welded by clod wash, using Q235 steel, Q345 steel, Q390 steel or Q420 steel systems
Into.
Further, longitudinal reinforcement, stirrup use HRB335, HRB400, RRB400 or HRB500 reinforcing bar
Further, the shaped steel shear key is made of Q235 steel, Q345 steel, Q390 steel or Q420 steel.
The solution have the advantages that unquestionable：
1. solid steel tube constrains reinforced concrete circular column, the strength of materials can be made full use of, fire-resistance anti-seismic performance is good, economical
It is profitable etc..
2. fabricated construction, with speed of application is fast, construction quality is high, construction environment improves, working condition improves, resource
The advantages that energy conservation, cost savings.
3. pier bottom groove is reserved in pier bottom, reserved shaped steel shear key or basic groove on basis, and pass through injection grouting material
Mode by the two connect fix；The more existing assembled column of which can effectively improve pier bottom with basic connection mode and connect with basis
The reliability and construction connect is more convenient.
