Description
Technical field
The utility model relates to the concrete columns that structural engineering field of reinforcement more particularly to a kind of steel pipe are reinforced.
Background technique
In current engineer application, after being frequently encountered building structure construction, strong concrete can be found through on-site test
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, usually by the concrete in concrete column, locally displacement (it is mixed to cut part
Solidifying soil, is then newly poured), integral replacement (after all cutting, newly-laid concrete), the methods of the section for increasing concrete column.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, Construction Support, which is arranged, be cannot achieve, so as to cause frame column concrete without
Method displacement；It such as enlarging section, then may will affect the use of building, such as occupy parking stall, or influence the overall stiffness point of structure
With to influence whole structural internal force, need to consider carefully.
Utility model content
For the defects in the prior art, the utility model provides the concrete column that a kind of steel pipe is reinforced, can retain compared with
More sections meets the requirement of construction, obtains biggish bearing capacity by replacing lesser sectional area, meets making for structure
With requiring, guarantees old concrete and newly-laid concrete and the common stress of steel pipe column, meet the safe handling of structure.
Postposition steel pipe column is added retaining in the concrete column that the steel pipe of the utility model is reinforced outside concrete column, described
The cross section profile of postposition steel pipe column is greater than the cross section profile for retaining concrete column, but their cross sectional shape is identical, the postposition
Be perfused with grout blanket in steel pipe column, the cross sectional shape of postposition steel pipe column is identical as the section of concrete column is retained, be it is rectangular or
Person is circle, and the cross section profile of postposition steel pipe column is identical as the outer profile of original structure concrete column, can not only be obtained biggish
Bearing capacity, and compared to more occupied spaces no before reinforcing.
Further, the inner surface of the postposition steel pipe column is fixed with peg, can allow grout blanket effectively and postposition
Steel pipe column concurs.
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 that the one end stretched out and retained outside concrete column, the outer end of transmission rod bend l-shaped, be allowed to and be 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 be 10mm, the grout blanket with a thickness of 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 be with
It is biggish to improve the intensity for retaining 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 material 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 self 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, pours into grouting material in 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 utility model are: the concrete column that the steel pipe of the utility model is reinforced, can retain more
Section meets the requirement of construction, obtains biggish bearing capacity by replacing lesser sectional area, the use for meeting structure is wanted
It asks, guarantees old concrete and newly-laid concrete and the common stress of steel pipe column, meet the safe handling of structure.
Detailed description of the invention
