Abstract

The invention relates to an industrial plant high-flatness and large-area concrete ground construction method. The industrial plant high-flatness and large-area concrete ground construction method is characterized by comprising following steps of a, selecting an appropriate construction machine; b, making and using a special stand for controlling the flatness; c, controlling settlement; and d, controlling dividing joints. The industrial plant high-flatness and large-area concrete ground construction method is advantaged in that the special stand for controlling the flatness is simple in structure and convenient to make, the concrete ground does not have obvious cracks and the differential settlement phenomenon, the dividing joints are cut tidily, and the deviation of the surface flatness of the whole cement concrete surface course is within 3mm.

Description

technical field [0001] The invention relates to a concrete floor construction method, in particular to a high flatness large-area concrete floor construction method for industrial workshops. Background technique [0002] Vietnam Baosteel Tank Hue main plant has a reinforced concrete floor construction area of ​​16,560 square meters. Reinforced concrete floor classification and practice requirements: (1) 200 thick cast-in-place reinforced concrete floor: 200mm thick reinforced concrete is pounded and wiped, anti-cracking steel 6@200, a layer of 0.2mm plastic film is laid under the concrete, lap joint Larger than: 100mm; 200mm thick sand and gravel cushion layer, sprinkle a layer of dry sand on the surface, backfill soil layered compaction, the compaction coefficient is not less than 0.94; (2) 300mm thick reinforced concrete can be pounded and plastered, double-layer two-way 12@ 200, lay a layer of 0.2mm plastic film under the concrete, and the overlap is greater than: 100mm;...
