Concrete bouncing back instrument, to test the comprcssive strength of concrete, is the widest concrete anti-compression of Site Detection
Intensity nondestructive detecting instrument, the ultimate principle of concrete bouncing back instrument are to use extension spring driving weight, and weight is clashed into constant kinetic energy
With the elastic stem of concrete surface perpendicular contact, local concrete is made to deform and absorb part energy, another part energy
Amount is converted into the bounce-back kinetic energy of elastic stem, and when the kinetic energy that rebounds is completely converted into potential energy, elastic stem bounce-back reaches ultimate range, instrument
The maximum bounce-back distance of elastic stem is shown by device with the name of rebound value (maximum distance and the ratio of extension spring initial length of rebounding)
Come, concrete can be detected by reisilometer.
Existing concrete bouncing back instrument is provided with transparent window in housing side.When detection is used, by transparent window
The rebound height of weight when watching test, therefore extremely inconvenience is operated, and reading accuracy is poor.Meanwhile, existing concrete
Reisilometer is using single spring as the elastic component for driving elastic stem.However, actual concrete to be measured is due to detection
The difference of occasion, often with multiple strength grade scopes, and the reisilometer range of single spring can only be fixed on certain model
In enclosing, this concrete very low for measurement intensity (for example, less than 10MPa) will produce larger error, and for intensity
Very high concrete (being greater than 70MPa) can because of no to scale thus cannot accurate measurement, or cause measured value distortion.
For the problems referred to above, technical staff's problem demanding prompt solution is a kind of concrete bouncing back instrument of exploitation, reasonable in design, is tied
Structure is simple, instead of single spring by the combination of double electromagnetic drivers, can increase the range ability of reisilometer, in increase
While journey scope, it is ensured that the precision of measurement, the scope of application is increased, and it is easy to operate, and reading is accurate, by showing
Device can reading, be a kind of preferable concrete bouncing back instrument.
