Problems solved by technology

[0005] The purpose of the present invention is to aim at the defects existing in the existing reinforcement methods, to provide a rapid reinforcement method that can significantly improve the bearing capacity and ductility of the reinforced bias column, and to solve the problem of increasing cross-section reinforcement on the original structure existing in the prior art. The size is generally large, which has a great impact on the self-weight of the structure, and requires formwork on site, and the maintenance period is long, so it cannot be put into use quickly; it also solves the problem of limited ductility improvement of columns reinforced by outsourcing angle steel and many construction components; at the same time, it solves the problem of It solves the problem of limited increase in bearing capacity after reinforcement of external viscose fiber reinforced composite materials; and avoids the problem of high technical requirements for external prestressed reinforcement method and difficult anchorage treatment

Embodiment

[0029] A method for quickly reinforcing a reinforced concrete eccentric column, comprising the following steps:

[0030] Step 1, making channel steel 2 for reinforcement matching the cross-sectional size of bias column 1, and reserving bolt holes on flanges 21 on both sides of channel steel 2;

[0031] Step 2, the two opposite concrete surfaces in the height direction of the cross-section of the bias column 1 are bonded anchorage areas 11, and the bonded anchorage areas 11 of the bias column 1 are polished and smoothed;

[0032] Step 3, install the channel steel 2 to the designed position, and drill bolts on the surface of the bonded anchorage area 11 of the bias column 1 according to the positions of the bolt holes reserved on the flanges 21 on both sides of the channel steel 2 Holes, and cleaning and reaming of holes;

[0033] Step 4, apply building structural glue on the bonded anchorage area 11 of the bias column 1, and put the channel steel 2 on it;

[0034] Step 5, inj...

Abstract

The invention discloses a method for rapidly reinforcing a reinforced concrete eccentric loading column. The method comprises the following steps: manufacturing a steel channel which is matched with sectional size of the eccentric loading column and used for reinforcing; reserving bolt holes in flanges on two sides of the steel channel; forming bond anchorage regions in surfaces of concrete on two opposite sides in the cross section height direction of the eccentric loading column, and polishing, clearing and flatting the bond anchorage regions; installing the steel channel to a designed position, drilling bolt holes in the surfaces of the bond anchorage regions of the eccentric loading column according to the positions of the bolt holes reserved in the flanges on two sides of the steel channel, and clearing and broaching the holes; smearing an building structure adhesive in the bond anchorage regions, and sleeving the steel channel; injecting the adhesive into the bolt holes in the bond anchorage regions of the eccentric loading column, and inserting paired pull bolts; screwing down nuts at two ends of the paired pull bolts, and well fixing the steel channel and the eccentric loading column. The method is less in adopted reinforcement component, simple in construction steps and short in construction period and can be put into use rapidly, and is capable of greatly improving the bearing capacity, lateral stiffness and seismic ductility of the column, and the column is good in overall performance and high in reliability.

Description

technical field [0001] The invention relates to a strengthening method, in particular to a method for quickly strengthening a reinforced concrete eccentric column. Background technique [0002] A large number of reinforced concrete columns in industrial and civil buildings have problems such as insufficient bearing capacity and other problems affecting safety and use functions due to design and construction defects or aging, damage and disasters in the long-term use process. Reinforcement is urgently needed . For example, in civil buildings, due to the reconstruction of building structures, the addition of machines in industrial plants and the overloading of bridge structures, the bearing capacity of the original structure is insufficient, and it is urgent to greatly increase the bearing capacity of reinforced concrete columns through reinforcement methods. [0003] At present, in the actual reinforcement of reinforced concrete eccentric columns, the reinforcement methods s...
