Cover protectometer
Technical field
It the utility model is related to architectural engineering detection device technical field, more particularly to a kind of cover protectometer.
Background technology
In building engineering structure acceptance test project, thickness of protection tier is one of dominant item.For steel
Tendon concrete structure, when thickness of protection tier is too small, it is impossible to effectively resist the intrusion of extraneous aggressivity example, and due to
Protective layer is gradually carbonized by the carbon dioxide in air, can not ensure that building service phase outermost layer reinforcing bar is in concrete alkalescence
In the protection of environment, it is easily caused steel bar corrosion and then component deteriorates;When thickness of protection tier is excessive, as caused by reinforcing bar about
Beam force is not enough to offset the convergent force of concrete, and concrete structure surface crack easily occurs, therefore, controls the reinforcing bar of concrete structure
Protective layer thickness is beneficial to improve structure durability.
Thickness of protection tier analyzer tests the thickness of protection tier of concrete structure according to the principle of electromagnetic induction.
Traditional thickness of protection tier analyzer is made up of probe and main frame, and both are connected by cable.Operating personnel wear main frame, hand
Probe is held to be detected.
Armored concrete survey meter on existing market is to use battery to be needed more after using a period of time as the energy
