One-time construction method for structural slab and surface layer of large-area emery floor

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...

[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
