The industrial workshop of a 3000m industrial workshop in Shanghai has high requirements on the levelness and surface crack resistance of the floor, and manual construction is not easy to control, and it is difficult to achieve standardization. The builder uses the whole series of products of Shanghai Yayao to carry out mechanized operation, and the construction process is highly flowed and mechanized, which ultimately achieves efficient operation and guarantees the overall quality of the floor.
Laser Leveling Machine for Preliminary Paving of Concrete
CLS-P300 Construction of Shanghai Yayao Hydraulic Laser Paver
The thickness of concrete construction is 20 cm. Laser transmitter is used to determine the height of concrete paving construction by transmitting laser signals. Laser receiver is used to measure whether the height of concrete is qualified. Laser leveller is then used to ensure that the concrete plane is kept at the design height. During the construction process, one person is responsible for moving the laser leveler and two persons are responsible for assistant front-end leveling.

Work with a disc
About 3-4 hours after the concrete paving (determined by the temperature and the condition of the base concrete), the concrete is pretreated (the excess bleeding is removed), and the best time is when no clear footprints appear. The single and double disc polishers are used to install the rubbing discs, and the concrete slurry is put forward after repeated rubbing during the initial setting of the concrete.

Spraying Wear Resistant Aggregate
It is suggested that 2/3 of the prescribed amount of NHARDTOP wear-resistant material should be evenly dispersed on the surface of concrete just after pulping. The water loss should be dispersed first near formwork, columns, doors, walls and pits.
Special materials can be dispersed more than twice according to specific conditions. 2/3 of the first throwing amount, 1/3 of the second throwing amount, and the time interval between the two throwing should not be too long.
Compacted aggregate-flattening
When concrete hardens to a certain degree, the polisher receives light.
Slitting Machine Cutting Concrete Expansion Joint
After completing the construction process efficiently and scientifically, it takes more than 28 days to maintain the floor. After the completion of the construction, sprinkle water to maintain, and lay Geotextiles to reduce water evaporation, so that the wear-resistant floor after the construction is kept in water.
Cut expansion joint after 24 hours of concrete sprinkler curing. Because the spacing of the wall pillars is about 7 meters, which meets the requirement of the gap between the expansion joints, the expansion joints are mainly distributed according to the structure of the wall pillars, forming a 7m*7m layout; the depth is about 6-7cm, and the gap is about 5mm.
Design sketch
Good flooring can not be separated from the perfect combination of human, machinery and concrete. Mechanized process construction can improve production efficiency, improve the flatness of flooring, reduce the labor intensity of workers, completely change the traditional construction mode, without the need to erect steel formwork and ashes. In the field of concrete construction, Yayao looks forward to helping you on the road of specialization.
