From above-mentioned technical proposal, it can be concluded that, a kind of concrete column provided by the embodiment of the utility model has following excellent
Point:
(1), due to the method using FRP pipe confined concrete models, (the i.e. hollow circuit cylinder that surrounds of FRP pipe so that protective layer
Body) the case where the destroying that fall off will not occur；Moreover, the FRP pipe of specific fibrage angle not only has superior tensile property,
Bigger hoop constraint power can also be provided than conventional bar construction, so that concrete is in three dimension stress state, improve core
The bearing capacity of heart concrete about 15% or more, while ductility also can be improved.
It (2), is not in due to reinforcing bar due to a kind of concrete column inside no-reinforcing-bar provided by the embodiment of the utility model
The brittle break broken and occurred suddenly, and chloride ion corrosion reinforcing bar need not be worried, seawater sea sand can be used as coagulation
Therefore the raw material of soil can construct on the island of resource shortage, meanwhile, preparation cost can also be obtained further
It reduces.
(3), due to FRP pipe than reinforcing bar from heavy and light, can effectively mitigate self weight, thus, under the extreme cases such as earthquake, mix
Solidifying earth pillar is also accordingly reduced by the destruction of geological process.
(4), since FRP pipe has the characteristics that anti-aging, corrosion-resistant, good insulating, internal coagulation can preferably be protected
Soil by the corrosion of natural environment, does not extend the service life of concrete column effectively.
(5), since FRP pipe can double as mold simultaneously, construction efficiency can be effectively improved, while FRP pipe price is lower than reinforcing bar,
It can reduce construction cost, therefore there is construction feasibility.
(6), ultra-high performance concrete has high compressive strength, high shear strength, toughness is big, ductility is big, energy to failure is high etc.
Feature, can be effectively reduced the residual deformation about 60% of column end, while can also reduce the diameter of concrete column and improve dissipation
Can, to reduce the destruction of earthquake bring.
(7), it since the cost of ultra-high performance concrete is high, from great disadvantage, is only used in end, remaining combined column is still
For common performance concrete, overall cost is cheap, is suitable for large-scale promotion.
In conclusion the utility model provides a kind of concrete column, the structure of the concrete column are as follows: FRP pipe, superelevation
Performance concrete and common performance concrete；The FRP pipe surrounds a hollow cylinder, and the ultra-high performance concrete pours into
The bottom of the hollow cylinder, the common performance concrete pour into the remainder of the hollow cylinder, the superelevation
The height of performance concrete is 1.5~3 times of the hollow cylinder outer diameter.The utility model additionally provides a kind of above-mentioned coagulation
The preparation method of earth pillar.In technical solution provided by the utility model, the hollow cylinder lateral confinement power that FRP pipe is formed increases
Add；Energy operative constraint inner concrete forms three dimension stress state, improves concrete crushing strength；And internal concrete is not
It can leak out and fall off, effective guarantee safety.A kind of concrete column provided by the utility model, solves in the prior art, reinforcing bar
Concrete column is easy to happen Concrete intensity insufficient under the extreme damages such as earthquake, sag of protecting coating, stirrup are broken and longitudinal steel
The technological deficiency of the security risks such as muscle buckling.
