Description

The invention relates to construction, in particular, to methods for producing floors of livestock buildings. A known method of making a floor / incorporating a base of lightweight concrete, laying a cement-sand strand on it. mortar with subsequent installation of a coating of asbestos cement plates PIJ. However, with this method of manufacture, no waterproofing of the floor is required. The closest in technical essence and the achieved result to the invention is the method of making the floor of the livestock building, including the laying on the base of the heat-insulating base layer in the form of cellular concrete, followed by the installation of a non-woven floor 23. With this method of manufacturing, the floor is made of cellular waterproofing concrete. A floor made by a known method has a considerable stoniness due to the use of hydrophobised concrete and, moreover, it does not provide the necessary waterproofing. The purpose of the invention is to reduce the cost of the floor and increase its operational qualities. . This goal is achieved in that according to the method of manufacturing the floor of the livestock building, including the one to lay a teloizolation underlying layer in the form of cellular concrete slabs with a subsequent laying of the coating on it, after installing the underlying cellular concrete mass with a bulk weight of 480 -680 kg / m, a hydrophobic substance is applied to their surface and the plates are impregnated to a depth of 0.005-0.1 of their thickness, after which a coating of polymer cement solution is applied to the hydrophobic substance used for impregnation of the underlying layer, Example 1. The planned rammed soil of cellular concrete with a bulk mass of 680 kg / m 0.15 m thick followed by the impregnation of their upper surface with a polyvinyl acetate emulsion to a depth of 1 mm. PW; This polyvinyl acetate emulsion filled all cracks, gouges and also the joints of the plates. Then the floor is kept for 1 hour, after which the top working layer of polymer cement solution, which is mixed on a polyvinyl acetate emulsion, is applied to the surface. Example 2. The slabs are laid on a splanted, compacted soil of cellular concrete with a bulk weight of 580 kg / m 0.15 m thick, followed by impregnating them to a depth of 5 mm by the upper surface of the polyvinyl acetate sludge, which filled the cracks, potholes and plate joints. After soaking for 2.5 hours, the top working layer is applied from the polymer-cement mortar, shut on. polyvinyl acetate emulsion. Example 3. Plates of cellular concrete with bulk oil of 480 kg / m 0.15 m thick are laid with their subsequent impregnation to a depth of 15 mm of the upper surface of the polyvinyl acetate emulsion, which filled all the cracks, hollows and joints of the plates. After soaking for 4 hours, the top working layer of polymer cement mortar, shuttered on a polyvinyl acetate emulsion, is applied to the surface of the plates. The results are presented in the table.

From tab. It can be seen that the proposed 60 method, floor devices, for example, a cattle-breeding room, provides high waterproofing properties of the floor, low thermal activity, which meets the requirements of 65

SNIP-11 99-77, as well, due to its simplicity and low consumption of materials, low cost. The use of cellular concrete with a density of 480-680 kg / m ensures its good impregnation with hydrophobic oil.

With substance, impregnation provides concrete, the difference in

the hardening of the upper layer is 1.5-6 times, the cost of these types of concrete also provides reliable waterproofing of 2.2 rubles / m, and the cost of the higher surface due to filling-up of 1.05 rubles / m and production

third, potholes and plate joints. 0.95, rub / m.

The cost of the proposed method 5 with the outside of the drainage of the proposed completion of the floor compared to the ba-sosa device floor in volume

callback lower by 4.2 rubles / m2 due to 20 thousand, m economic effect

the use of conventional, rather than hydropho, will amount to 84 thousand rubles.
