Working principles that should not be ignored by concrete laser screed
The concrete laser screed is to remove projecting concretes with scraper blades and then cut off the projecting concrete from the left to the right with a distribution screw rotating in a single direction. When the elevation reached the design standardd, the remaining material will be sent to the right of the screw. The bottom slope of the flattened beam is similar to that of a trowel in terms of function, and during the process of vibration and smashing, the trowel here will play an effect of scraping flattening. The vibration of the vibrator inside is generated by eccentric blocks at a frequency of three thousand times per minute and driving the entire flattened beam so as to jointly produce vibrations on the concrete.
It is not necessary to pull control lines during concrete laser screed leveling, and it does not need to support a side template to control the ground elevation, which is actually controlled by the implementation of computer at the frequency of ten times per second. This can realize high-speed construction, and the ground elevation can also be precisely controled. The laser emitter can be arranged independently, and the floor elevation always taken the plane formed by the rotating laser beam emitted by the laser emitter as the controlling plane.
