Description
Technical field
The utility model is related to building structure aseismatic and reinforcement technique field, specifically relates to a kind of for Concrete Structures of Tall Building
Armored concrete anti-seismic strengthening device.
Background technology
Reinforced column is a kind of structural elements for being widely used in building.In frame structure and frame shear wall structure
In, reinforced column simultaneously as main compression member and lateral resistant member, its Compressive Bearing Capacity and anti-seismic performance it is good
The bad security to whole building thing has significant effect.Due to design and the misoperation of work progress, the increase of load and
The effects such as the damage of burst earthquake, concrete column is it is impossible to meet use requirement, and under rarely occurred earthquake effect, and post is usually produced
Larger diagonal crack, causes later stage rehabilitation cost larger, or even is difficult to repair.
Conventional post reinforcement technique has increasing section reinforcing, and encased steel plate is reinforced, the method such as outer viscous fibre sheet material.Increase is cut
Face method makes the area of section of post increase larger, takes building more using space；It is poor to there is fire line in encased steel plate rule, reinforcing bar
The problem of corrosion, poor durability；Viscous fibre sheet material method needs to use structure glue sticking outside, and smell is larger, not environmentally, makes for a long time
The problem of there is aging, poor durability with rear structure glue.There is rate of utilization of strength in encased steel plate method and outer viscous fibre sheet material method
It is not high the problem of, uneconomical.
The content of the invention
For defect present in prior art, the purpose of this utility model is to provide a kind of Reinforced Concrete Reinforcement
Device, post structure carries out the reinforcing of bending resistance and shear behavior, to meet security performance and performance.
In order to solve the above-mentioned technical problem, the utility model, which is adopted the following technical scheme that, is achieved：
A kind of Reinforced Concrete Reinforcement device, described post includes at least one side, including is coated in concrete column
At least high ductility concrete topping of one side, described high ductility concrete topping extends to stirrup to concrete column center,
The thickness of described high ductility concrete topping is 20~40mm；
The groove to concrete column central fovea is provided with described concrete column and high ductility concrete topping contact surface,
Fill concrete formation shear key in groove, a diameter of 20~40mm of described groove, the depth of groove is 15~30mm.
Compared with prior art, the beneficial effects of the utility model are：
(1) the high ductility concrete that the utility model is used is a kind of with high intensity, high ductility, high-durability and Gao Nai
The construction material of lesion capability, during as reinforcement material, the thinner thickness of required surface layer, only 30~45mm remove what is chiseled out
The more former section of column section only increases by 15~30mm after thickness of concrete cover, reinforcing, can not change substantially sectional dimension and
In the case of anti-side rigidity, the Seismic Bearing Capacity of post is improved more than 1.5 times, the ductility of post improves 1.6 times.
(2) high ductility Concrete Filled is prepared into shear key by the utility model in a groove, can save the modes such as bar planting
Shear key is made, construction is simple, convenient, fast, saves the duration；This bracing means need not set reinforcing bar, save assembling reinforcement, steel
The complicated procedures of forming such as muscle anchoring, construction is simple, convenient, fast, saves a large amount of durations.
(3) the utility model device easy construction, one side reinforcing, two-sided reinforcing, three faces available for concrete column are reinforced
Reinforced with four sides, application flexibly, realizes the different reinforcing demand of concrete column.
