Description

(54) - THREE-LAYER FLOOR PLATE

one

The invention relates to construction and can be used in the manufacture of durable, sanitary and hygienic requirements, floors in livestock buildings.

The floor slab construction is made of monolithic claydite-concrete on a cement binder 1.

Such a cooker is characterized by poor resistance to aggressive effects and does not meet sanitary and hygienic and operational requirements.

Closest to the invention is a three-layer floor slab comprising layers filled with a large-porous aggregate, combined by a binder, while the upper layer is monolithic with a polymeric binder 2.

A plate of this design is homogeneous, has good resistance to aggressive effects, but has a high thermal conductivity coefficient, a high content of polymer binder and high cost.

The purpose of the invention is to improve the thermal performance, reduce the cost

while maintaining resistance to aggressive effects.

The goal is achieved by the fact that in a three-layer slab of the floor, including layers filled with a large-pore aggregate, combined with a monolithic polymer binder with an upper layer, the aggregate is made in the form of granules;

Q them, and in the lower layer, the granules are monolithic with a bitumen, polymer-cement or cement binder.

The drawing shows the slab structure. The slab consists of the lower layer 1, made of dense and waterproof cement, bitumen or polymer concretes, the middle layer 2, made of large-pore concrete, the upper layer 3, made of polymer concrete. Each layer of the slab is made of a material that most fully meets its functional purpose. The lower layer, made of waterproof low-cost materials, gradually passes in the middle of the height into large-pore concrete, which is characterized by low thermal conductivity. The large-pore concrete at the upper face, as the cavities are filled with polymeric solution, passes into polymer concrete, which is characterized by good resistance to aggressive effects, increased strength, and wear resistance. A floor slab is prepared as follows. Expanded clay, diatomite, thermolite or light artificial (natural) crushed stone is thoroughly mixed with cement, polymer-cement or bitumen mortar, which is taken in the amount of 5-20 ° / o from the volume of the aggregate. The resulting mixture is placed in a mold and cured after vibrating. Then, the resulting product is poured with a polymer solution, which is taken in an amount of 3-8% of the volume of the aggregate and, under the action of vibrational vibrations, fills a part of the voids in the product. After curing, the product is removed from the mold. In a slab of this construction, the coefficient of thermal conductivity is 1.5–2 times, the content of the polymer binder is 2–3 times, and the cost is 1.2–1.3 times less than the expanded clay polymer concrete slabs with the same durability. The invention includes a three-layer floor slab comprising layers filled with a large-pore aggregate, combined with a binder, while the upper layer is monolithic with a polymeric binder, characterized in that, in order to improve its heat-engineering properties, reduce the cost while retaining the corrosive effects, the aggregate is made in the form of granules, while in the middle layer the granules are glued together with a binder with the formation of air cavities between them, and in the lower layer the granules are monolithic bitumen, polymer cement or cement s binder Sources of information taken into account in the examination 1.
