Problems solved by technology
[0004] The traditional construction method is to make a concrete structure layer first, and then add a 5cm fine stone concrete leveling layer on the structure layer after the strength of the structure layer is stable, and lay an emery surface layer on the surface; the investigation found that the main problems are poor ground flatness and ground cracks other quality defects

Embodiment Construction
[0022] The first stage (concrete construction of the structural layer):
[0023] Determine the elevation of the formwork surface and the elevation of the concrete floor surface, and measure them to the four-corner reinforcement of the frame and the main reinforcement of the frame beam respectively.
[0024] Install the beam slab bottom formwork——bind the beam slab steel bars——install the beam side formwork——place the height control point of the steel bar head on the floor——concrete pouring, scraping, finishing, and lifting.
[0025] The second stage (corundum surface layer construction):
[0026] The first time of spreading the material - the first time of pulp extraction - the first smoothing - the second time of material spreading - the second time of pulp extraction - the second time of smoothing - calendering - smoothing - polishing.
[0027] Sprinkling means spreading wear-resistant materials directly on the surface of the newly set concrete.
[0028] The first step of...

Abstract
The invention provides a construction method for a carborundum wear-resisting floor of a large spinning workshop and belongs to the field of building construction. The construction method is characteristics in that a concrete structural layer and a carborundum wear-resisting surface layer are formed at a time, construction of the carborundum wear-resisting surface layer is conducted between concrete initial set and final set, curing is conducted through a curding agent after concrete final set, and the firm and wear-resisting ground with the thickness being 3 mm is formed on the surface of the concrete structural layer. According to the construction method for the carborundum wear-resisting floor of the large spinning workshop, quality common problems, such as hollowing, peeling and cracking, of the workshop floor can be effectively avoided, the ground wear resistance is improved, and the ground service life is prolonged.
Description
technical field [0001] The invention belongs to the field of building construction, and in particular relates to a construction method for emery wear-resistant floors in large-scale spinning workshops. Background technique [0002] The ring spinning workshop built in the spinning base of Korla City, Xinjiang, has a construction area of 26644.7 square meters, a length of 180.74 meters, and a width of 147.42 meters. The ground is a 300mm thick well-graded Gobi soil cushion, a 200mm thick reinforced concrete base, and the surface layer is emery. Wear-resistant ground, set a full-length trench and cable trench at an average interval of 9m, the trench width is 1.5m, the average depth is 1.3m, the cable trench width is 600mm, and the depth is 1000mm. The building layer is one floor. [0003] The wear-resistant floor of the workshop has an area of 26644.7 square meters, which is a super-large area of wear-resistant floor. [0004] The traditional construction method is to ma...
