RU117479U1 - BUILDING FINISHING MATERIAL - Google Patents

Abstract

1. Building finishing material in the form of a sheet, consisting of micro-granular concrete with an inorganic binder, reinforced with a non-metallic mesh in one or more layers, characterized in that the content of sand filler in concrete, having a particle size of less than 200 microns, varies from 0 to 80% , and the mesh has a mesh size of at least 2 mm, with one side of the sheet made smooth, and the other rough with sawtooth protrusions. ! 2. Construction finishing material according to claim 1, characterized in that a decorative layer is applied to the smooth side of the sheet.

Description

The proposed technical solution relates to building materials, namely sheet materials for interior and exterior decoration of premises, including residential, as well as for factory finishing of building structures.

Known sheet decoration material, consisting of several layers, one of which is made of fiberglass (1).

Known sheet finishing material consisting of concrete on a polymer bond in which there is a reinforcing layer of gauze (2).

Known sheet finishing material, consisting of non-metallic mesh reinforced micrograin concrete with an inorganic binder (3).

The problem to which the claimed technical solution is directed is to create a universal sheet finishing material for interior and exterior decoration, which has high frost resistance and compressive and bending strength.

This task is achieved by the fact that the sheet finishing material is made of micrograin concrete with an inorganic binder. Micrograin sand filler has a grain size of less than 200 microns. Its content in concrete is from 0 to 80%.

Micrograin concrete in the proposed material is reinforced with a non-metallic mesh, for example, polymer or fiberglass, the mesh size of which is at least 2 mm. Reinforcement is made by one or several grids. The proposed finishing material has one smooth side with a decorative layer and one rough, with sawtooth protrusions to increase the area of the adhesive joint.

The technical result, which is caused by the above-mentioned features of the technical solution, is the ability to quickly and easily laborious finish building structures, both in the factory and at the construction site, to protect the walls of buildings and structures made of materials with high porosity and low frost resistance, for example, foam concrete or ordinary brick .

The use of a material with different densities and, accordingly, porosity allows the proposed material to be used both indoors, where increased vapor permeability is required, and outside, where increased watertightness and low vapor permeability are required.

In Fig 1 presents a sheet of finishing material with one reinforcing layer. Figure 2 shows a sheet of finishing material with several reinforcing layers of non-metallic mesh.

Sheet finishing material consists of microgranular concrete 1, inside of which one or several layers of reinforcing non-metallic mesh 2 are located. On one side of the material is a decorative layer 3, on the other sawtooth protrusions 4.

Table 1 shows the results of studies of consumer parameters of a material 2 mm thick.
