Problems solved by technology
[0002] The zero-layer board (floor) of Tianjin FAW Toyota's new energy welding workshop is 300m long, 232m wide, and 250mm thick. There are cable trenches and small equipment foundations locally, double-layer bidirectional φ12 steel bars, and wear-resistant metal aggregates on the surface plus curing agent. Block construction requires a length of 20m, a width of 20m, and a height difference of 3mm within 3m. Normal manual leveling construction cannot meet the leveling requirements, and the laser leveling machine weighs about 600kg. The machine cannot be constructed on the steel bar.
[0003] Therefore, there are above-mentioned inconveniences and problems in the known floor levelness control method.

Embodiment 1
[0021] see now figure 1 , figure 1 It is a schematic diagram of a large-area floor leveling machine paving and track device according to an embodiment of the present invention. The large-area floor flatness control method of the present invention comprises the following steps:
[0022] a. Craft track making
[0023] The main beam is made of 100*60*3 square steel, the auxiliary beam is made of 60*40*3 square steel, and the short column is made of 100*60*3 square steel. part;
[0024] b. Adopt Z-840 laser leveling machine for paving and leveling, so that the concrete laser leveling machine can walk on the craft track for paving and leveling operation;
[0025] c. Use a vibrating ruler to lift the pulp and level it;
[0026] d. N-900 double-disc troweling machine for finishing.
[0027] Among construction machinery and equipment, concrete laser leveling machine paving concrete leveling operation, using vibrating ruler for concrete slurry leveling operation, and double-disc ...

The invention discloses a large-area floor flatness control method. The method is characterized by comprising the following steps of a, manufacturing a track; b, spreading concrete by using a concrete laser leveling machine; c, carrying out slurry extraction and leveling on the concrete by using a vibration leveling ruler; and d, finishing the concrete by using a double-disc troweener The large-area floor flatness control method has the advantages that the problem that a laser leveling machine cannot conduct construction on reinforcing steel bars is solved, a construction progress is smooth, all workloads are successfully completed within a planned progress, manpower and a construction period are saved on, and the requirement for large-area floor flatness is met.
Description
technical field [0001] The invention relates to a method for controlling the evenness of a floor, in particular to a method for controlling the evenness of a large-area floor. Background technique [0002] The zero-layer board (floor) of Tianjin FAW Toyota's new energy welding workshop is 300m long, 232m wide, and 250mm thick. There are cable trenches and small equipment foundations locally, double-layer bidirectional φ12 steel bars, and wear-resistant metal aggregates on the surface plus curing agent. The block construction requires a length of 20m, a width of 20m, and a height difference of 3mm within 3m. Normal manual leveling construction cannot meet the leveling requirements, and the laser leveling machine weighs about 600kg. The machine cannot be constructed on the steel bar. [0003] Therefore, there are above-mentioned inconveniences and problems in the known floor levelness control method. Contents of the invention [0004] The purpose of the present invention is...
