Problems solved by technology

[0002] At present, the hardened ground of buildings such as modern industrial plants, shopping malls, exhibition halls, indoor parking lots and warehouses requires high wear resistance and crack resistance, and the ground needs to be hardened, wear-resistant, and crack-resistant. The overall cast-in-place ground is cracked, and the construction method of laying steel mesh and pouring fine stone concrete is adopted. The usual thickness of the concrete is 40mm. The upper and lower double-layer steel meshes are costly. Furthermore, the existing hardened ground is prone to defects of varying degrees such as peeling of the hardened layer and ground cracks, and the ground has poor impermeability and durability. request, needs to be improved

Embodiment Construction

[0023] The present invention is described in further detail below:

[0024] A construction method for wear-resistant and crack-resistant hardened ground, comprising the following steps in sequence:

[0025] 1) Base surface treatment: Sprinkle water to wet and clean the floor. First, use a shovel to polish the surface of the base into a rough surface, and then evenly brush a layer of cement slurry mixed with 801 glue for sweeping treatment. The 801 glue is Zhongnan brand. The place of origin is Shanghai, and the weight ratio of 801 glue to cement slurry is 1:2.

[0026] 2) Sub-compartments support formwork: set up glass strip sub-compartment compartments, the support formwork direction is consistent, not criss-cross, and the sub-compartment support formwork width is preferably 4m~6m strip-shaped intervals.

[0027] 3) Pouring the 50mm thick polypropylene fiber concrete floor: pouring according to the compartment, using steel rollers to repeatedly roll compaction and smoothing,...

Abstract

The invention discloses a method for constructing wear-resistant and crack-resistant hardened ground, which is applied to hardened ground of buildings such as modern industrial factory buildings, shopping malls, exhibition buildings, indoor parking lots, warehouses and the like. The method sequentially comprises the following steps of: brushing slurry on the surface of a base layer, namely watering to wet and clean the base layer and uniformly brushing a layer of 801 glue-doped cement slurry on the surface of the base layer; pouring, compacting and trowelling a polypropylene fiber concrete floor with the thickness of 50mm, removing bubbles and free water from the polypropylene fiber concrete by using a vacuum water absorption device, and removing laitance on the surface of the concrete after the concrete is initially set; laying a hardened wear-resistant layer and trowelling for 1 to 2 hours; calendaring by using a trowelling machine; and spreading a layer of BZK-15 surface liquid molded concrete curing agent to cure the ground. The hardened ground poured by the construction method has the characteristics of high durability, permeability resistance and crack resistance, and low construction cost.

Description

【Technical field】 [0001] The invention relates to a hardened ground construction method, in particular to a wear-resistant and crack-resistant hardened ground construction method. 【Background technique】 [0002] At present, the hardened ground of buildings such as modern industrial plants, shopping malls, exhibition halls, indoor parking lots and warehouses requires high wear resistance and crack resistance, and the ground needs to be hardened, wear-resistant, and crack-resistant. The overall cast-in-place ground is cracked, and the construction method of laying steel mesh and pouring fine stone concrete is adopted. The usual thickness of the concrete is 40mm. The upper and lower double-layer steel meshes are costly. Furthermore, the existing hardened ground is prone to defects of varying degrees such as peeling of the hardened layer and ground cracks, and the ground has poor impermeability and durability. Requirements, room for improvement. 【Content of invention】 [000...
