[0003] However, the traditional construction method is to make the 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. This method is prone to hollowing, shelling, and cracks. Moreover, the net height of the floor increases, and the load of the structural slab also increases, which brings certain safety hazards to its quality

example 1
[0042] Example 1 New construction project in Guangdong
[0043] The new project is located in an industrial zone in Guangdong Province, with a total construction area of 85012.14㎡, a single-story portal steel frame structure, a structural plate thickness of 30cm, and a concrete strength grade of C30. The construction method of one-time forming of the concrete structure board and the emery wear-resistant ground is adopted, which improves the wear resistance of the ground, avoids hollowing, shelling, and cracks, and the flatness of the large-area floor meets the requirements and the color is uniform. The construction period was shortened by 50 days. Economic benefits, saving 21 yuan per square meter, the total wear-resistant floor of the project is 81,200 square meters, and the total cost reduction is 1.7052 million yuan.

[0044] Example 2 The new factory construction project of a limited company
[0045] The new plant construction project has a total construction area of 51,700 square meters, a frame structure, a structural plate thickness of 200cm, and a concrete strength grade of C30. The construction method of one-time forming of the concrete structure board and the emery wear-resistant ground is adopted, which improves the wear resistance of the ground, avoids hollowing, shelling, and cracks, and the flatness of the large-area floor meets the requirements and the color is uniform. The construction period was shortened by 30 days. Economic benefits, saving 21 yuan per square meter, the total wear-resistant floor of the project is 22,500 square meters, and the total cost reduction is 472,500 yuan.

Abstract
The invention discloses a one-time construction method for a structural slab and a surface layer of a large-area emery floor. According to the method, the structural slab and the surface layer of an emery floor are formed once, construction of the wear-resistant emery surface layer is performed between initial setting and final setting of concrete, a curing agent is used for curing after final setting, a finished product is well protected, the firm and wear-resistant floor about 3 mm thick is formed on a concrete structural layer, emery is scattered on fresh concrete of the structural slab directly, construction of a fine aggregate concrete leveling course is not needed, procedures are reduced, time is saved, a construction period is shortened, the cost is saved, clear height of a storey is guaranteed, load of the structural slab is reduced, phenomena such as hollowing, peeling, cracks and the like with the traditional method are avoided, by means of one-time forming of the structural slab and the emery surface layer of the floor, the emery surface layer and a base course are firmly bonded and not prone to hollowing or peeling, so that quality is guaranteed, and the floor is applicable to ground in industrial places, wharfs, parking lots, commercial stores, logistics warehouses, workshops and the like.
Description
technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a one-time construction method for a large-area carborundum floor structure plate and a surface layer with fast construction speed, guaranteed headroom, reduced structural plate load, improved construction quality, and low cost. Background technique [0002] Emery floor is a new type of ground building material product introduced by foreign companies in the 1990s. It is suitable for ground decoration needs in industrial sites, docks, parking lots, commercial stores, and logistics warehouses. It has the advantages of wear resistance and compression resistance, dust reduction, hard surface, easy cleaning, economical and durable, etc. Due to the characteristics of convenient construction, no pollution, low price and long service life, it has achieved amazing development speed in cities with relatively developed coastal industrial economies such as the Yangt...
