Laser screed features
(1)The theory of laser screed is the use of laser technology, closed-loop control technology and highlyp precise hydraulic system, which is realized under the automatic control of the computer to achieve, and this is the most prominent character that makes it different from other floor construction technologies.
(2)The principle of laser screed is to rely on the hydraulic-driven leveling head and coordinate with the laser system and computer control system for simultaneous completion of the leveling work. The flat head is equipped a scraper with an integrated design, vibrator and leveling plate, and it has integrated all the work of leveling, flatening, vibrating and pounding into one and could achieve one-time completion. The computer control system could conduct automatic adjustment of elevation for 10 times per second in real time, while the vibration frequency of the vibrator with balanced design could be 3000 times/min.
(3) The laser emitters used to control the ground elevation are independently arranged so that the floor elevation is not controlled by the template and does not produce cumulative errors.
(4) The laser screed can also automatically controll the vertical and horizontal gradient, which are also unified finished by laser system, computer systems, hydraulic systems, and mechanical systems. On the ground with complex shapes having high standards on drainage, optional three-dimensional special-shaped surface treatment system can also be equipment for achievement.
