Description
Technical field
This utility model relates to a kind of reinforcement of concrete post device, is specifically related to a kind of rectangle reinforced column local stiffening device.
Background technology
Steel-tube support post also has in addition to having that Strength of High Performance Concrete is high, deforming little advantage that the ductility of concrete filled steel tube is good concurrently, consumes energy, shock resistance and the advantage such as anti-seismic performance is good, present stage in multilamellar, high-rise structure is extensively applied with high-rise building, Longspan Bridge, building surface in big industrial factory etc., easy construction, reduction of erection time, reduce cost, obtain good economic effect.Yet with some buildings'storey-adding transformation, original structure system can not meet requirement for bearing capacity；Additionally there are some building or built building is due to aspects such as design or constructions, there are some defects；After meeting with the disaster such as earthquake, fire, there is damage in existing reinforced concrete structure, and its bearing capacity and stiffness declines；These problems directly influence the safe handling of building structure so that the reinforcing of reinforced concrete structure and reparation become particularly significant.
Present stage, reinforce normal concrete structure frequently with modes such as increasing section reinforcing, displacement concrete strengthening, external prestressing strengthening, steel-encasing strengthening, affixing steel plate reinforcement, the reinforcing of stickup fibrous composite, pre-stressed carbon fiber composite plate reinforcings.Increasing section is reinforced and is made New-old concrete cooperation bad, and structural plasticity is improved less by cooperative transformation poor performance.Steel-encasing strengthening make outsourcing shaped steel and former component can not overall work, each other can only independent stress, outsourcing steel performance utilization rate is low, and globality is poor.Therefore, in the urgent need to a kind of reinforced steel concrete net-structure apparatus.
Utility model content
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of rectangle reinforced column local stiffening device, including reinforced column, multiple bar planting and square casing, described bar planting partial symmetry is implanted in the reinforced column needed reinforcement, in reinforced column and bar planting are wrapped in by described square casing, between square casing is by reinforced column, gap arranges steel fiber reinforced concrete or inorganic grouting material.
As preferably, the square casing outer wrapping multilamellar FRP cloth of described a kind of rectangle reinforced column local stiffening device, the number of plies is 1-4 layer.
As preferably, the sleeve pipe that the square casing of described a kind of rectangle reinforced column local stiffening device is docked by two halves forms, and described square casing thickness is 3～10mm.
The beneficial effects of the utility model are:
1. the rectangle reinforced column reinforced with this device is compared with new construction, both the waste of natural resources and social resources can have been reduced, bearing capacity and anti-seismic performance can be improved again, extend its service life, there is the advantages such as the duration is short, expense is low, it is adaptable to high-rise and high-rise building, Longspan Bridge pier stud, the local stiffening etc. of building surface in big industrial factory.
2. the vertical muscle in increasing section method for strengthening and stirrup consumption are converted into square casing by this bracing means, utilize square casing and twine outward FRP cloth, on the premise of not increasing steel using amount, to reach the Confinement effect good to original reinforced column, improve bearing capacity and the ductility of core column.
3. make full use of FRP cloth, light weight, intensity height, the features such as corrosion resistance is strong, improve the corrosion resistance of square casing, with square casing cooperative bearing, common constraint core concrete post.
4. square casing can be as pouring the template of high performance concrete, simple to operate, easy construction, the reduction of erection time, reduces engineering cost, and it is high to reinforce reliability.
5. the technology by fiber concrete, self-compacting concrete of creativeness combines, make this novel high-performance concrete have good mobility, stability, uniformity and degree of compaction, and be introduced in the middle of steel-tube support structure for engineering reinforcement.
6. this composite reinforcement post belongs to a kind of novel steel tube xoncrete structure, it combines the advantage of concrete filled steel tube and both increasing section method for strengthening, bearing capacity and the ductility of original steel core concrete column can be greatly improved, compare existing bracing means and there is the strongest technical advantage.

Fig. 2 is reinforced column and ruggedized construction elevational schematic view；
Wherein, 1-reinforced column, 2-bar planting, 3-concrete, 4-square casing, 5-FRP cloth.
Detailed description of the invention
In conjunction with accompanying drawing, this utility model is illustrated,
This utility model provides a kind of rectangle reinforced column local stiffening device, including reinforced column 1, multiple bar planting 2 and square casing 4, it is characterized in that: described bar planting 2 partial symmetry is implanted in the reinforced column 1 needed reinforcement, in reinforced column 1 and bar planting 2 are wrapped in by described square casing 4, between square casing 4 is by reinforced column 1, gap arranges steel fiber reinforced concrete or inorganic grouting material, described square casing 41 to 4 layers of FRP cloth of outer wrapping 5.
The sleeve pipe that described square casing 4 is docked by two halves forms, and described square casing 4 thickness is 3～10mm.
Reinforced column local stiffening method is by employing this utility model device:
A arranges symmetrical bar planting 2 at original reinforced column 1 place of needing reinforcement；
B arranges square casing 4 in reinforced column 1 periphery, in reinforced column 1 and bar planting 2 are wrapped in by described square casing 4；
C, in square casing 4 outer winding FRP cloth 5, after treating the solidification of FRP cloth 5 adhesive, pours steel fiber reinforced concrete or the inorganic grouting material of self-compaction between square casing 4 and reinforced column 1.
Embodiment described above be only technical scheme rather than to this case design restriction.The present invention can be modified or equivalent by those skilled in the art without departing from spirit of the invention and spirit.If these are changed and equivalent belongs in the middle of scope of the presently claimed invention, it all should be contained in the middle of scope of the presently claimed invention.
