Description
Technical field
The present invention relates to concrete component reinforcing technical field, more particularly to a kind of large-tonnage concrete column substitution reinforcement knot
Structure and reinforcement means.
Background technology
Engineering construction is checked and accepted and the later stage is in use, be frequently encountered concrete column quality dissatisfaction or concrete column reaches
Reinforcing, reinforcing generally use increasing section method for strengthening, the steel-encasing strengthening of the prior art are needed less than design strength
Method and conventional concrete displacement method, wherein increasing section method for strengthening increase concrete column stress by increasing section and cut, outside
Packet reinforcement method of steel shapes increases concrete column rigidity and compression strength by outsourcing shaped steel, and conventional concrete displacement method passes through increase
Reinforced column underpinning cap of pile replaces the concrete of defect.
However there is certain defect in the above method, such as increase strengthened section method makes the axis for being reinforced concrete column top
It is larger to active force, and make the concrete column section after reinforcing than former section increase it is more, to be unfavorable for decorations with
And visual perception and space utilization.And there is no defects existing for fundamentally solution concrete column for steel-encasing strengthening method, only
It is to carry out stress by shaped steel, the maintenance and protection used in the later stage requires relatively high.And conventional concrete displacement method needs
Heavy-gauge steel reinforced concrete conversion platform is added, therefore construction infection is larger and construction surface is larger.

Carry out the overall construction intensity of substitution reinforcement.
Sealing strip is carried out after the above-mentioned reinforcement structure of peripheral hardware is fixedly mounted, then after pre-buried multiple grout nipples along gap, is led to
It is overpressurized perfusion and bonding agent is poured into gap between internal beam steel plate 2 and concrete column 1, wait for bonding agent from part grout nipple part
It emerges the rear enclosed grout nipple and the voltage stabilizing perfusion 10min after bonding agent until whole grout nipples are emerged；It is then allowed to stand maintenance extremely
Few 3 days, during which forbids to beat concrete column 1 and each component for being attached thereto is until bonding agent fully cures.
After compactness after detecting bonding agent solidification is not less than 95%, cut using artificial or small-sized machine branch to be added
Gu the rejected region of concrete column should dig deep 4~5cm and ensure defective locations again wherein being waited for outside rejected region cutting
It is adequately cleared, then cleans the interface of new and old component, after ensureing interface without floating dust and rubble, brushing interfacial agents, then
To being cut region formwork and High Strength Non-shrinking Filling Material being perfused, wherein grouting material strength grade should be at least than former concrete column
1 strength grade of concrete improves a grade.Then formwork is removed after carrying out maintenance component by code requirement, detection is replaced portion
The concrete divided, which whether there is the defects of voids and pits and carry out rebound, examines structural strength.It should be noted that the present invention is real
Example is applied using branch's displacement method into line replacement, can first replace the coagulation for replacing another half section after the concrete of a half section again
Soil.
After by inspection, replacing structure removes shaped steel hoop 7 and deep floor after reaching structural strength, to additional internal beam
Steel plate 2 and reinforcement angle steel 5 carry out surface derusting, and to entire concrete column 1 and additional component surface smearing thickness 2cm or more
Epoxy resin mortar as plaster protective layer, it is final to restore to original decorations layer.
The foregoing is merely the preferred embodiment of the present invention, are not intended to limit the scope of the invention, every at this
Under the design of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/it is used in it indirectly
