Jacking and reinforcing method for buckling reinforced concrete column

Abstract

The invention discloses a jacking and reinforcing method for a buckling reinforced concrete column. The method comprises the following steps: step one: manufacturing a steel bracket; step two: installing the steel bracket and a jacking device; step three: installing an unloading device; step four: arranging a laser range finder; step five: unloading the buckling reinforced concrete column; step six: jacking the buckling reinforced concrete column; step seven: chipping away a crushing area of the buckling reinforced concrete column and concrete near the area, and enabling a buckling reinforcedsteel bar to be exposed; step eight: welding a new reinforced steel bar at the edge side of the buckling reinforced steel bar; step nine: supporting and installing a template, preparing the high-strength fine aggregate concrete, and pouring a chipped area; step ten: restoring the reinforced concrete column; step eleven: implanting a new longitudinal bar and a spiral stirrup around the buckling reinforced concrete column after reinforced; and step twelve: restoring a frame beam and a floor. The reinforcing method is short in operation project period, rapid in efficacy, simple in construction process, and capable of realizing simple, efficient and economic repair to the buckling reinforced concrete column.

Description

Technical field [0001] The invention belongs to the technical field of building reinforcement, and specifically relates to a method for jacking and strengthening a compression-buckled reinforced concrete column. Background technique [0002] With the rapid economic development, the demand for industrial and civil buildings is increasing. On the one hand, in a large number of infrastructure construction, problems of improper design and improper construction will inevitably occur, such as insufficient concrete pouring due to excessively dense component reinforcement, poor concrete fluidity, or insufficient bearing capacity of reinforced concrete columns. The resulting compression and crushing of the reinforced concrete column concrete, and the compression of the steel bars in the column directly affect the safety and use of the building; on the other hand, the change in the use of the building makes the actual load of the structure larger than the design value, which causes the str...

AI Technical Summary

Problems solved by technology

On the one hand, in a large amount of infrastructure construction, problems of poor design and improper construction inevitably occur, such as excessive reinforcement of components, poor concrete pouring caused by poor concrete pouring, or insufficient bearing capacity of reinforced concrete columns. The resulting crushing and crushing of reinforced concrete columns, and buckling of the steel bars in the columns directly affect the safety and use of the building; even crushed

The above situations of poor design and improper construction need to be avoided, but cannot be eliminated, and the situation of changing the use of buildings is also inevitable

[0003] In the above situation, once the buckling of the concrete column occurs, whether it is in the construction stage or it has been delivered for use, if it is removed and rebuilt, the construction cost will be greatly increased, or the normal use of the residents will be affected. Therefore, a kind of work is urgently needed The jacking reinforcement method with short construction period, quick results, simple construction technology, and less wet work can deal with the buckling of reinforced concrete columns caused by factors such as poor design, improper construction, and changes in building functions, so as to achieve simple, efficient, and economical repair
