Description
Technical field
The present invention relates to structural engineering field of reinforcement more particularly to a kind of postposition steel core concrete columns.
Background technology
In current engineer application, after being frequently encountered building structure construction, strong concrete can be found through Site Detection
Inadequate phenomenon is spent, such as all dismounting is reformed, and can be wasted a large amount of human and material resources and can be brought certain negative shadow to society
It rings, so the method for being all made of consolidation process under normal circumstances.
Processing method under normal circumstances typically locally replaces the concrete in concrete column（It is mixed to cut part
Solidifying soil, is then newly poured）, integral replacement（After all cutting, newly-laid concrete）, increase concrete column the methods of section.Work as bottom
When portion's floor frame column concrete strength is too low, design requirement is much not achieved in the bearing capacity of frame column, when top has constructed one
After the floor of fixed number amount, due to the pressure of upper floor, setting Construction Support cannot achieve, so as to cause frame column concrete without
Method is replaced；Such as enlarging section, then the use of building may be influenced, such as occupy parking stall, or influence the overall stiffness point of structure
With to influence whole structural internal force, need to consider carefully.
Invention content
For the defects in the prior art, the present invention provides a kind of postposition steel core concrete column, can retain more cut
Face meets the requirement of construction, obtains larger bearing capacity by replacing smaller sectional area, meets the requirement of structure,
Ensure old concrete and newly-laid concrete and the common stress of steel pipe column, meets the safe handling of structure.
Postposition steel pipe column, the postposition steel is added retaining in the postposition steel core concrete column of the present invention outside concrete column
The cross section profile of tubing string is more than the cross section profile for retaining concrete column, but their cross sectional shape is identical, the postposition steel pipe column
Inside it is perfused with grout blanket, the cross sectional shape of postposition steel pipe column is identical as the section of concrete column is retained, and is rectangular or is
The cross section profile of circle, postposition steel pipe column is identical as the outer profile of original structure concrete column, can not only obtain larger bearing capacity,
And compared to no more occupied spaces before reinforcing.
Further, the inner surface of the postposition steel pipe column is fixed with peg, can allow grout blanket effectively with after
Steel pipe column is set to concur.
Further, the reservation concrete column is implanted into transmission rod, and the outer end of transmission rod is cast in grout blanket；Transmission rod
For reinforcing bar, reinforcing bar outer end refers to stretching out the one end retained outside concrete column, and the outer end of transmission rod bends l-shaped, is allowed to and is in the milk
Layer combination is more firm.
Further, the transmission rod implantation retains the depth in concrete column and is not less than 10cm, it is ensured that transmission rod and reservation
The consolidation strength of concrete column.
Further, the wall thickness of the postposition steel pipe column is 10mm, and the thickness of the grout blanket is 90mm, the length of the peg
Degree is 80mm, and grout blanket uses high-strength expansive concrete, and the sidewise restraint of postposition steel pipe column and high-strength expansive concrete can also
Larger raising retains the intensity of concrete column.
Further, the transmission rod and peg interlaced arrangement, comprehensive stress performance are good.
Further, the grout blanket is poured in postposition steel pipe column using C50 grouting materials and is formed.
Further, construction method is as follows：By calculate analysis original structure concrete column periphery rooted out it is a certain proportion of
Section makes it meet the requirement of the dead weight bearing capacity of construction period, and remaining part is to retain concrete column, is retaining concrete
Column is implanted into transmission rod, and postposition steel pipe column is added outside, grouting material is poured into postposition steel pipe column, and it is mixed to apply utilization of hour reservation
Solidifying earth pillar reliably supports top-out, not only easy for construction without in addition setting up support construction, but also safety
Good, postposition steel pipe column is welded using steel plate, level weld seam requirement first-order weld.
The beneficial effects of the invention are as follows：The postposition steel core concrete column of the present invention, can retain more section to meet
The requirement of construction obtains larger bearing capacity by replacing smaller sectional area, meets the requirement of structure, ensures old mixed
Solidifying soil and newly-laid concrete and the common stress of steel pipe column, meet the safe handling of structure.
