The magnetic attraction between iron powder between reinforcing bar and in reinforcing bar and performance of concrete column confined continuously fluctuates, and thus makes reinforcing bar, iron powder common
In concrete internal vibration.
By above method, the vibration source of inside concrete can be significantly increased, to largely promote effect of vibrating
Fruit, while enhancing the intensity of performance of concrete column confined.
Detailed description of the invention
Fig. 1 is one embodiment schematic diagram that this performance of concrete column confined pours auxiliary device.
Fig. 2 is schematic diagram of Fig. 1 embodiment when being inserted into performance of concrete column confined.
Specific embodiment
In Fig. 1, embodiment illustrated in fig. 2, it includes base enclosure 1 which, which pours auxiliary device, 1 lower part of base enclosure
Equipped with one section of electromagnet 2, the jack (not marking) of pluggable reinforcing bar 3 is evenly equipped on the end face of 2 lower section of electromagnet；The electricity
After the direction of magnetization of magnet 2 is parallel to the reinforcing bar 3 being inserted into the jack, and electromagnet 2 magnetizes, magnetism can be transmitted to respectively
On reinforcing bar 3 in the jack；The electromagnet 2 is coupled in the power module (not shown) in the base enclosure 1.
Above-mentioned auxiliary device, the power module at least need that alternating current can be provided to the electromagnet 2.As a result,
The auxiliary device when in use, need to only be inserted into reinforcing bar 3, and reinforcing bar 3 is inserted into template 4 in the jack of end face below electromagnet 2
In wet concrete 5 in, be then passed through alternating current to electromagnet 2, then 3 intensity of magnetization continuous wave of reinforcing bar in each jack
It is dynamic, to make the magnetic attraction between each reinforcing bar 3 continuously fluctuate, so that each reinforcing bar is continuously shaken in wet concrete 5, to mixed
Solidifying soil 5 forms good effect of vibrating；And after vibrating operation, directly reinforcing bar 3 can be stayed in concrete 5, with structure
At the keel of concrete 5, keel setting and operation of vibrating are completed with a gas, greatly improves and pours efficiency.
Above-mentioned performance of concrete column confined pours the application method for also having one kind special of auxiliary device, and this method includes following step
It is rapid: reinforcing bar 3 being inserted into each jack first, makes 2 excitation of electromagnet described in the electric power source pair of module, and each reinforcing bar 3 is inserted
Enter in iron filings heap, in 3 adsorption iron filings of reinforcing bar；Then each reinforcing bar 3 for adsorbing iron filings is inserted into performance of concrete column confined, and
After making 2 power down of electromagnet, each reinforcing bar 3 is extracted into performance of concrete column confined, after rotating by a certain angle, again insertable into performance of concrete column confined；So
Fluctuate the intensity of magnetization of reinforcing bar 3 continuously 2 input AC of the electromagnet electricity again afterwards, thus make between each reinforcing bar 3, and
The magnetic attraction between iron powder in reinforcing bar 3 and performance of concrete column confined continuously fluctuates, and reinforcing bar, iron powder is thus made to shake in concrete jointly
It is dynamic.
By above method, the vibration source of inside concrete can be significantly increased, to largely promote effect of vibrating
Fruit, while enhancing the intensity of performance of concrete column confined.
In addition, it can be made to have two kinds of selected modes the power module, to provide direct current to the electromagnet 2
Electricity and alternating current；When inhaling powder mode, i.e., when making reinforcing bar 3 attract iron powder, electric power source pair of module electromagnet 2 is made to provide direct current,
So that its relative to alternating current, make iron powder adsorption obtain it is more firm (when exchange electrical excitation, 3 surface of reinforcing bar can also adsorb iron powder,
But iron powder has oscillation phenomenon in rebar surface), when vibrating mode, i.e., after the reinforcing bar 3 in each jack is inserted into concrete, make
Electric power source pair of module electromagnet provides alternating current.
When not configuring above two selected mode to the power module, can also make the power module includes frequency conversion
Module, and equipped with the frequency adjustment switch of the frequency-variable module in the base enclosure 1, to adjust the electricity according to actual needs
The input frequency of magnet, to adjust the vibration frequency of reinforcing bar 3.Such as, during inhaling powder, make the input frequency zero of electromagnet 2,
Being equivalent to makes 2 input dc power of electromagnet, and when being directed to various various sizes of performance of concrete column confined, it can rule of thumb adjust steel
The vibration frequency of muscle 3, to realize effect of most preferably vibrating.
In order to abolish experience limitation, can also make the power module includes one-chip computer module and frequency-variable module, in each institute
After stating the insertion concrete of reinforcing bar 3 in jack, i.e., when vibrating mode, the one-chip computer module makes the output of the frequency-variable module
Frequency continuously adjusts once from small to large, and when the input current for recording frequency-variable module reaches maximum, corresponding output frequency,
It is denoted as resonant frequency；Then the frequency-variable module is made persistently to export exciting current to electromagnet 2 by the resonant frequency.As a result,
The auxiliary device can be made in vibrated concrete, automatically keep optimal vibration efficiency.
In addition, an electronic range measurement head can also be arranged on the end face of 2 lower section of electromagnet, the electronic range measurement head exists
When detecting that front obstacle distance is less than 10cm, the power module is made to power by mode is vibrated to the electromagnet 2.This
Sample, when reinforcing bar 3 does not have insertion concrete, electronic range measurement head and the barrier in front of it are apart from each other, and mixed to the insertion of reinforcing bar 3
After solidifying soil, the upper surface of performance of concrete column confined is close apart from electronic range measurement head, is less than 10cm under normal circumstances, as a result, according to obstacle
The distance of object, that is, can determine whether reinforcing bar 3 is inserted into concrete, so that the auxiliary device can be automatically into mode of vibrating, and nothing
It must manually switch mode.
Further, the ranging head is sound radar, and wave length of sound is 0.01mm ~ 0.1mm, so that the sound wave can
Across iron powder heap, and wet concrete can not be passed through.When can avoid reinforcing bar 3 as a result, in the iron powder heap for being inserted into surfacing,
It is mistaken in insertion concrete.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
