Description

The invention relates to the construction, in particular to the construction of gypsum concrete wall stones, mainly for the exterior walls of low-rise heated buildings, such as rural manor-type buildings.

The aim of the invention is to increase the heat-shielding properties of the stone, its strength and reduce the material intensity.

The drawing shows a wall stone

The wall stone includes the non-gypsum-concrete layers I, separated by liners 2 of the silica-pore, and the ratio of the thickness of the liner (5g) to the thickness of the hypo concrete layer (Sj.) Is

Wall stones are made next (in their own way.

Slabs of thickness 50–60 mm are made of the required dimensions during their production. The gypsum concrete, for the mixture, is prepared in a mixer of cyclical or continuous action, depending on the method used for the formation of stones.

Forming stones with a small. the volume of their production is carried out in collapsible individual metal forms in the following sequence; Compiled and written by M.Vinogradov Editor S. Patrushev Tekhred L. Serdyukova Proofreader V. But ha

The slabs are placed in the design position and the gypsum-concrete mix is laid into the free space of the mold and the mold is vibrated for 3-8 seconds. After 10–20 minutes, the mold is opened, the stone is removed from the pallet and sent for drying or hardening in air-dry conditions of the workshop.

With significant production volumes, the stones are molded by extrusion. In this case, the prepared gypsum-concrete mixture is fed into the extruder receiving hopper and then with a screw into the mouthpiece, which also continuously serves plates of silicon-pore. Ready-made raw stones continuously emerge from the SchItyky mine exit, which are further processed, as in the production in metal forms.
