Description
Technical Field
The invention relates to a masonry structure quality nondestructive testing technology, in particular to an electromagnetic power mortar rebound instrument device.
Background
The mortar rebound instrument is a detection device suitable for the detection of the compressive strength of masonry mortar in sintered common brick masonry of industrial and civil general buildings. This is the fastest, simplest and most economical test method to obtain masonry mortar quality and strength.
The construction principle of the mortar rebound tester is that a regression equation and a curve of the mortar strength, rebound value and carbonization depth value are established by utilizing the correlation between the surface hardness of the mortar and the compressive strength of the mortar, and the regression equation and the curve are used for evaluating the strength of the mortar.
The mortar rebound instrument mainly comprises a rebound system, a value indicating system, an instrument shell part and the like: the impact rod in the impact system mainly transmits the kinetic energy of the impact hammer to the tested mortar test piece, and transmits the rebound energy after impact to the impact hammer to enable the impact hammer to rebound for a certain distance, the impact tension spring mainly stores the energy and endows the impact hammer, and the impact hammer is an energy carrying member and a connecting element between the impact system and the indicating system. The rebound value indicated by the pointer slider in the indicating system is the distance for driving the bouncing hammer to move when the bouncing hammer rebounds after impacting the bouncing rod.
The indicating system is fixed on the instrument shell and keeps the relative position and movement relation with the flicking system. The pointer of the indicating system returns to zero by compressing the spring to drive the guide flange so that the flick system is restored to the non-flick state and brought to the set position.
The adjusting bolt on the instrument tail cover is used for controlling the stroke (unhooking point) and the take-off point of the elastic hammer, so that the height of the adjusting bolt is not allowed to be changed at will once determined.
The mortar rebound instrument can obtain reliable test effect only by correct use and operation, and the concrete operation is as follows:
1. in the testing process, the axis of the resiliometer is always perpendicular to the surface of the mortar, the striking rod of the resiliometer is propped against the surface of the mortar, the light pressure resiliometer enables the button to loosen the striking rod and extend out of the casing of the resiliometer, and the hook is hooked with the striking hammer.
2. And uniformly pressing the extended bouncing rod to the surface of the mortar, when the condition that the mortar is about to be unhooked is reached, adjusting the verticality of the rebound appearance to the test surface, slightly pressing to enable the bouncing hammer to unhook to bounce, repeating the actions, continuously bouncing on one measuring point for three times, and not shifting, then reading and recording a certain rebound value marked on the graduated scale for the third time, if the condition is unfavorable for reading the rebound value, pressing a button, locking a machine core, moving the rebound appearance away from the surface of the mortar of the wall, and then reading and retrieving the rebound value.
3. The flick rod is reextended to restore to the normal state for the next point test.
4. The operation should be repeated according to the requirement during each test.
As described above, the existing mortar rebound apparatus relies on the manual firing of the striking rod and the manual return of the striking hammer by the worker, and the operation strength of the worker is high, which is time-consuming and laborious.
