Description

Technical field

The invention relates to a method for fixing a facing material through a low-strength slab insulation using a toothed support-distributing plate when insulating building facades.

State of the art

An outer wall block is known (Patent RU 173585 U1, Published: 08/31/2017 Bull. No. 25), including a concrete block with a facade, mainly vacuum layer, on the inner surface of which a layer of slab insulation is installed and fixed with a composite dowel, where the second end of the dowel fixed to the formwork, which forms a gap with the insulation to accommodate the bearing layer of concrete.

The disadvantage of such a wall block is that mineral wool is used as a slab insulation, which eventually loses its shape and thermal insulation qualities.

There is a method for erecting a multilayer outer wall of a building (Patent RU 2607846 C1, Published: 20.01.2017 Bull. No. 2), including the erection of a wall frame consisting of racks and crossbars, the installation of outer and inner walls separated by an air gap and the placement of a heater between them, which differs by the fact that, prior to the installation of the outer wall, mounting strips are fixed on the crossbars of the frame, then an additional layer of slab insulation is attached to the mounting strips, posts and crossbars, and the mounting strips are installed at the entire height of the building wall between the frame posts with a step equal to the size of the additional layer of slab insulation, and the insulation is mounted in horizontal rows with dressing of vertical seams and fixed from the side of the additional layer of slab insulation to the mounting strips using self-tapping screws and spacers with a plug.

The disadvantage of this method is that a mineral wool-type slab insulation is used. When using slab insulation such as aerated concrete, fastening to the carrier layer using self-tapping screws will lead to cracking of aerated concrete, the use of plastic spacers is ineffective.

The fundamental difference of the proposed method is the method of fixing the bracket to the supporting base through aerated concrete using a support-distributing toothed plate and stud anchors. Aerated concrete is a low-strength fine-mesh material with a closed porous structure. The use of support plates for anchoring allows you to distribute the load on aerated concrete and does not destroy the fragile insulation.

The fastening design provides the possibility of building a heat-insulating layer of various thicknesses, regardless of the length of the bracket.

The support-distributing toothed plate is made of stainless steel 1.5 mm thick, 150x150 mm in size, with a central hole for various stud diameters - 8 mm, 10 mm, and 12 mm, and with a 90° bend on two opposite sides with teeth at the ends. The structural assembly of the anchoring and the support-distribution plate takes the load from the attached structure of the façade cladding.

The adopted method minimizes heat loss through heat-conducting inclusions, which are the bracket attachment points, which is typical for hinged "ventilated" facades with various types of facing materials.

The technical task when using the proposed method is to fasten the facing material of the facade structure through a low-strength plate insulation on the facades to the supporting base, without deformation of the insulation.

The essence of the invention

The technical result of the invention is the insulation of facades using aerated concrete with a uniform distribution of the load from the fastening structure on the slab insulation, the exclusion of crushing, punching of low-strength material.

Aerated concrete insulation can be used to insulate the facades of buildings with exterior walls made of various materials, including heavy and lightweight concrete, reinforced concrete, hollow and solid brick masonry and ceramic stones. The insulation is glued with mineral adhesives and additionally fixed with special anchors.

Anchor installation procedure:

1. carry out the marking of the surface of the insulation boards for anchoring;

2. drill holes in the wall through the insulation plate to fix the studs (anchoring elements);

3. clean and blow through the drilled holes with a compressor;

4. fill the holes with adhesive and install the pin;

5. fasten the support-distribution plate to the slab insulation, while the pin protrudes from the central hole of the plate;

6. The supporting bracket of the subsystem is attached to the protruding stud, on which the facing material is subsequently attached.

Implementation of the invention

Using the method of fastening a slab insulation made of aerated concrete using a support-distributing toothed plate allows you to fix the facing material through a low-strength insulation to a supporting base using anchor fasteners.

The method is manufacturable, allows you to arrange a heat-insulating layer of various thicknesses, the thickness of the heat-insulating layer is limited by the bearing capacity of the metal stud of the anchor fastening.
