Abstract

The invention relates to the construction, in particular, to the technology of the device for heat insulating backfilling with the use of expanded perlite sand, and makes it possible to reduce the labor intensity and improve the efficiency and manufacturability of the work. The method of thermally insulating building structures involves feeding perlite sand using a pneumatic pressure method under a mat of air-permeable material previously laid on an insulated surface, which is removed before leveling the perlite sand. The leveled surface is moistened with a mineral water immobilized in water and, after impregnation, compacts the heat insulating layer, thus forming the heat insulation after curing the reinforced coating.

The invention relates to the construction, in particular, to the technology of the device for insulating thermal fillings using injected perlite sand.

The purpose of the invention is to reduce labor intensity. noBbiQjeHne of efficiency and workability.

The method is reinforced as follows.

On the pre-prepared surface of the attic ceiling, a mat of fiberglass 2.5X 2.5 m in size is laid, under which flexible fabric mantle winds. pipeline for supplying expanded perlite sand. Pearlite sand is delivered to the place of installation by cement masses and from the pneumatic system through flexible material pipelines is injected under a fiberglass mat. In this dusting polnosi.yu missing. Then the mat is removed; 1 etsi, and the pas 1 is a layer of exfoliated psd.chita with I)) of the special batten leveled over the entire insulated surface of the slab.

The process of moistening the products from the bridges that are on the floor. Humidification of the perlite sand (carried out with lime milk, 1.15–1.3; c.1 using known spraying agents for ei4) is estimated at 2.0–3.5 l / m. This ensures that p) the flare of the surface s.

all the way up, no matter what else,

thermal insulation is 0.15 strength of 0.25 MPa.

In the process of moistening the expanded perlite sand with lime milk, simultaneously, the wooden structures of the beams are also treated, which, to a certain extent, improves their flame retardant properties.

This method, in comparison with the known method, makes it possible to comprehensively mechanize the main technological operations and simplify the work technology, eliminating the need to install cement-sand blasting, significantly reducing labor intensity and material consumption by 30–40 ° / o, eliminating seasonality and Due to all this, to increase the efficiency and manufacturability of the method of thermal insulation of building structures.
