The floor of the facility
(57) Abstract:The invention relates to the field of construction and can be used in the manufacture of floor in your facility. The technical result - the reduction of the complexity of the manufacturing process, the reduction of thermal conductivity and increased chemical resistance. In a floor construction of the facility, including internal and external hydraulic system, the internal hydraulic system formed as a result of seminolecounty waterproof chemical resistant polymer solutions in the lower and upper areas of the porous skeleton formed by the bonding of the filler particle size above 10 mm 1 Il. The invention relates to the field of construction and can be used in the manufacture of gender in livestock pens.Known floor of the facility, including asbestos cement floor, the base of lightweight concrete and screed made with grooves forming the air gap, which are used to prevent supercooling of the animals during the winter period (see ed. St. USSR N 543723, class E 04 F 15/12, 1977). The disadvantage of this floor is that in the winter they are not what the patient should therefore thermal activity due to heating of the soil. In addition, these floors are short-lived due to corrosion of asbestos-cement coating.The closest technical solution to offer is the floor of the facility, including internal and external hydraulic system, designed for heating or cooling the floor. Internal hydraulic system formed of lightweight concrete, which serves as a base screed made with grooves forming an air layer and cover the asbestos. External hydraulic system consists of a tank with fluid, is placed above the level of the screed, the discharge device placed below the level of the ties uniting their pipelines equipped with locking devices (see ed. St. USSR N 688583, class E 04 F 15/12).This floor is characterized by a high complexity of manufacturing and high thermal conductivity. In addition, these floors are short-lived due to corrosion of asbestos-cement coatings and screeds.The technical effect is to reduce the complexity of the manufacturing process, the reduction of thermal conductivity and improved chemical resistance.The invention consists in that in a floor construction of the facility, on the I-porous skeleton, formed by gluing grains of filler particle size above 10 mm, chemically resistant polymeration hard consistence with the inclusion of fine aggregate in the upper area of the cross section of the plate, and a monolithic lower zone and the bonding of the frame takes place simultaneously waterproof, chemically resistant polymer solutions using as filler Portland cement, while the number of polimerrastvora take 10-15% of the volume of coarse aggregates.In the formation of macroporous skeleton filler take a size above 10 mm to form interconnected voids. When using aggregate particle size below 10 mm, the formation of sealed voids, which reduces the permeability of the armature fluid.The drawing shows the construction of the floor. Internal hydraulic floor is made as follows. The aggregate size of 10 mm is thoroughly mixed with 10-15% of its volume of polymer solution, put the mixture on the base 1 and vibroplate, with one part of polymer solution glues grain filler in the porous frame 2, and the other flows with grain filler and forms the bottom layer of the plate 3. After a the amount of 5-8% of the volume of aggregates for the formation of the upper layer 4. Porous frame 2 connected to an external hydraulic system, i.e. from one side of the pipe 5 with a capacity of 6 to contain the liquid, for example water, and on the other hand - with the drain device 7. The liquid reservoir 6 is installed above the level of the frame 2, and the discharge device 7 is at the bottom of the frame 2. On the pipe 5 is installed shut-off valves 8.The polymer solution for the formation of the lower layer 3 and the porous frame 2 has the following composition (in wt. PM): of epoxy resin ED-20 - 100; polyethylenepolyamine - 10; Portland - 150.Polymer solution for seminolecounty voids of porous frame 2 in the upper part of the formation of the layer 4 has a composition (wt.h.): epoxy resin ED-20 - 100; polyethylenepolyamine - 10; Portland - 150; quartz powder - 250.In the summer of porous frame 2 internal hydraulic fill water with cold water. The values of heat capacity and conductivity of the water is higher than that of air, so the water increases the coefficient of thermal activity, compensates for the increase in soil temperature in the summer. This improves thermal comfort of the animals. In winter the water is drained from macroporous calcarenitic.Example. Thermality gravel fractions of 10-20 mm is thoroughly mixed with 10% of its volume of polymer solution, the resulting mixture is placed in the form dimensions HH mm and vibroplasty. Polymeric compound glues aggregates in porous frame and forms the bottom layer of the slab. After curing the product within one day to the plate that mounts the external hydraulic system and produce a monolithic macroporous voids frame in the upper part. After curing for 28 days in normal temperature and humidity conditions were tested.The coefficient of the chemical resistance of polymer solution for seminolecounty voids of porous skeleton in the acidic environment of the livestock buildings after 6 months of keeping amounted to 0.98, and the coefficient of thermal conductivity of the floor plate thickness of 20 cm was 0.19 W/moC. the Ratio of chemical resistance samples of asbestos-cement sheet (prototype) used to cover the upper part of the floor plate in the acidic environment of the livestock buildings, after 6 months of incubation was 0.69, and the coefficient of thermal conductivity of the floor plate 20 cm thick amounted to 0.30 W/moC.From comparison of predlagaet, and the ratio of the chemical resistance of the top layer of the floor slab above 1.4 times. The floor of the facility, including internal and external hydraulic system, characterized in that the internal hydraulic system formed as a result of seminolecounty macroporous skeleton formed by the bonding of the grains of the filler particle size above 10 mm chemically resistant polymeration hard consistence with the inclusion of fine aggregate in the upper area of the cross section of the plate, and a monolithic lower zone and the bonding frame is carried out simultaneously waterproof chemical resistant polymer solutions, using as filler Portland cement, while the number of polimerrastvora take 10 - 15% of the volume of coarse aggregates.
FIELD: construction engineering, in particular, floor construction methods.
SUBSTANCE: method for building floors includes setting up beacons on base and applying porous building mixture onto base, as which construction compound foaming after being applied or foamed preliminarily is used. In first case, construction compound is applied onto base in form of layer, height of which after end of foaming exceeds height of beacons, sheet cover is placed onto beacons before beginning of foaming and is exposed until completion of foaming and precipitation of compound under effect from weight of cover. In second case, construction compound is applied onto base in form of layer, height of which exceeds height of beacons, after than onto layer of compound after its hardening sheet cover is placed and is exposed until completion of compound precipitation under effect from weight of cover. In case when construction compound applied onto base only performs function of tie for next sheet cover, it is recommended prior to placing to process sheets of cover with composition, increasing adhesion of sheet material to concrete; sheets of cover for provision of additional rigidity may be fastened to beacons and/or hardened layer of compound. In case of working conditions for premises allow concrete floor, sheet cover, after hardened construction compound accumulates hardness, is removed and used repeatedly at other sections. If construction compound applied to base performs function of tie for cover, different from one used during compound hardening, it is recommended to process sheets of cover prior to placement with composition decreasing adhesion of sheet material to concrete.
EFFECT: simplification of technological process.
