Production and mounting method of nano cement-based composite ultrahigh-strength artificial stone board

Abstract

The invention provides a production and mounting method of a nano cement-based composite ultrahigh-strength artificial stone board. The nano cement-based composite ultrahigh-strength artificial stoneboard comprises a board body material, reinforcing meshes and fibers and T-shaped nuts. The preparation of the board body material uses ultrahigh-strength mortar reaching above C100, and the ultrahigh-strength mortar adopts high-grade cement, silica fume, slag powder, sandstone aggregate with particle size being below 6mm, polycarboxylate superplasticizer and water-binder ratio below 25. Board production equipment has functions of high-frequency vibration, strong compression and vacuumizing and can discharge bubbles in the board, compress and suck moisture in the board and extract gas in the board to increase the density of the board so as to reach the ultralow water-binder ratio needed by ultrahigh-strength concrete. Various defects such as proneness to fading, proneness to breaking, poorfreeze-thaw resistance and short service life caused by the fact that a common-strength cement-based artificial stone board is poor in weather resistance, low in strength and low in density.

Description

technical field [0001] The invention relates to the field of architectural decoration, in particular to the production of a nano-cement-based composite ultra-high-strength artificial stone plate and an assembly-type quick dry-hanging installation method. Background technique [0002] The walls of existing buildings are decorated with the effect of stone materials. There are mainly two methods: wet paste and dry hanging. Wet paste is to use sticky mortar to paste the board on the wall. The viscosity of the mortar will decrease after a long time, and the weight of the board is relatively heavy. Large, it is easy to cause falling accidents, and the wet paste of mortar is easy to cause efflorescence and fading on the surface of the board, which has been basically eliminated. At present, the dry hanging method is mainly used, and the dry hanging installation has the following processes: [0003] 1. Natural stone is made into decorative panels by cutting, grinding, burning, sandb...

Problems solved by technology

There are certain disadvantages in the above processes: 1) Since the natural stone is already in a solid state, it can only be connected to the outside by slotting and drilling. Since the natural stone itself is relatively brittle, in order to prevent falling off accidents caused by chipping and cracking, therefore It is stipulated that the thickness of the dry-hanging stone should not be less than 25mm. Due to the large thickness, the weight per square meter exceeds 65 kg, so the metal skeleton carrying the stone needs to be thickened to carry its weight, resulting in a comprehensive cost of skeleton production cost and stone installation cost. It is extremely high, and at the same time, the heavy stone makes the building infrastructure also need to be enlarged, resulting in an increase in construction costs. Because natural stone is naturally formed, it has a large color difference, which is easy to cause architectural disfigurement and affect the appearance, and the mining of natural stone damages the environment. Pollution

2) Ceramic imitation stone bricks (boards): All ceramics need to be fired at high temperature to form, and also can only be slotted and drilled to be connected externally. Since the tiles are used for dry hanging for a short time, there is no standard for their thickness. If thinner tiles are used, due to the high brittleness of porcelain itself, slotting is easy to make it crack, and the bending resistance and impact resistance are worse. Low, there are potential safety hazards. In order to ensure safety, some existing dry-hanging tiles have the thickest thickness of 40mm. Although safety is guaranteed, the increase in thickness will also have the same disadvantages as natural stone.

Ceramics are fired at high temperature, which wastes energy and is prone to pollution, and clay mining damages the environment

3) The inventor's patent is to use cement-based artificial stone slabs for dry hanging. Although the problems of slotting and drilling and the production process are more environmentally friendly, the cement-based artificial stones are all produced with ordinary strength formulas, so that the slabs need to be maintained A certain thickness can guarantee its safety and service life, and ordinary strength plates have defects such as poor weather resistance, low strength and compactness, and high water absorption

The hook is inconvenient for production, processing and transportation, and the screw card installation efficiency is low and the precision is poor
