Floor slab with decorative surface protection layer

Abstract

The invention discloses a floor slab with a decorative surface protection layer. The floor slab is made by a manufacturing method comprising the following process steps of paving; concrete vibrating, leveling and punning; maintaining; coarse grinding the surface of a floor slab layer to remove a laitance surface layer; forming a compact layer, wherein concrete repair solution and powder ground from the coarse grinding step are mixed; forming a strengthened layer, wherein concrete enhancer is downwards permeated for 3mm-5mm from the surface of the compact layer, and the concrete enhancer and concrete are reacted to form the strengthened layer; fine grinding and polishing; forming a protection layer, wherein permeation solution is applied to the strengthened layer and is permeated downwards, and the permeation solution and the concrete are reacted to form the protection layer. According to the floor slab with the decorative surface protection layer provided by the invention, materials can be at least saved, the overall anti-pressure ability of the floor slab layer is improved, the load and the construction cost of buildings are reduced, and meanwhile, the environment can be protected.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a floor slab with a decorative protective layer. Background technique [0002] According to the records on page 20 of GB50037-2013 "Code for Design of Building Floors" and the techniques commonly used in the prior art, the building floor includes floor (concrete) structural layer + leveling (horizontal) cushion + finishing layer (epoxy, ceramic tile) , stone, wooden floor, etc.), the basic structural layer of the ground floor should be the surface layer, cushion and foundation; the basic structural layer of the floor ground should be the surface layer and the floor slab. When the basic structural layers of the ground floor and the floor of the floor cannot meet the use or construction requirements, other structural layers such as bonding layers, isolation layers, filling layers, and leveling layers can be added. It can be seen that the current floor is a sandwich structur...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing pouring floor slab technology and equipment lack effective means to control the levelness and flatness;

[0005] 2. The technical process of directly processing the concrete floor layer into a decorative layer has more defects (such as fineness and compactness) than stone tiles and other effects;

[0006] 3. The combination of the above two points lacks innovation, exploration and technical improvement

[0008] 1. The method of floor slab + other structural layers + surface layer leads to an increase in the process, resulting in waste of man-hours and materials

[0009] 2. The actual distance between the structural layer and the design elevation of the floor finish and the error of levelness lead to uneven thickness of the leveling layer, easy to delaminate, hollow and crack

[0010] 3. The design strength of the leveling layer is often lower than the design strength of the floor layer, resulting in a decrease in the overall compressive strength

[0011] 4. Since the thickness of the floor is limited by the regulation of the reinforcement protection layer (2cm above the reinforcement), the method of superimposing the finishing layer, especially the leveling layer or cushion layer + finishing layer, will greatly increase the load and cost of the building

[0012] 5. The production and transportation of decorative materials consumes a lot of energy (transportation increases carbon emissions, the use of decorative materials such as stone tiles and wooden floors consumes natural resources, pollutes the environment and is irreversible and non-renewable), and most decorative materials cannot do so It has the same life span as the building floor, and the cost of renovation and disposal is huge
