The USSR№№360519, 481755, 560108, 563542, 590554, 606037, 608040, 667770, 834375, 1449776, 1651043, 1656097, 1815516; U.S. patent No. 4134545; French patent No. 2250076; patents Germany No. 2834014, 3035946; Japan patent No. 4-145 and others).Of the known methods and devices of the most effective the tent Japan No. 4-145, E. 04 5/48, 19.08.85,) and device for its implementation, which is selected as prototypes.At the specified method on the rods of the reinforcement cage floor slabs placed heating pipes that are attached to the rods. After that, the reinforcing cage and the heating pipes are laid concrete mix. The resulting design refers to the Central heating system, heating elements (heating pipe) which combined with slabs and used for the floor (ceiling) space heating during operation. Priority for use of heating systems with the incorporation of steel pipes in thickness ceilings and floors owned by Russian engineer C. A. the Yakhimovich (1907) (Skanavi A. I. heating. M., 1988).However, the known method and device that provide radiant heating of the premises is not allowed to increase concrete strength and quality of concrete structures throughout its thickness.An object of the invention is to increase the concrete strength and quality of concrete structures throughout its thickness.The problem is solved by the fact that according to the way concrete monolithic reinforced concrete slabs, including stowage and securing the rods armature is inuu pipe is placed in a corrugated waterproof and breathable shell, made of tough heat-resistant polymer material, remove excess moisture and air by the method of vacuum by gradually extracted from the shell of the heating pipe, after completion of the pumping process heating return pipe in place, connect it to the heating system and is used in the “warm floor, with heating pipes made of polymer-metal material.The problem is solved in that the device for pouring a monolithic concrete slab containing reinforcing cage floor slabs, rods which are attached to the heating pipe can be laid on concrete mixture, heating pipes made of polymer or polymer-metal material, placed in corrugated waterproof and breathable shell made from tough heat-resistant polymer material, with the possibility of retrieving them from the shell and install in place, the output of each of the heating pipe connected to the vacuum system, consisting of serially connected to the adapter precipitator for water and sand, the vacuum pump and filter for air emitted into the atmosphere, each will topete the seals.The heating pipes can be made in the form of a single coil, spiral and coil with parallel pipe-laying the supply and return water.A special feature of this method is that water extraction and removal of air is in the process of internal vacuum processing concrete through heating pipes laid in the floor structures, which speeds up the process of curing and provides uniformity in the thickness of the structure on the entire area of overlap. This uses a special vacuum device in the form of a porous tube with the sealing lip and the filter attached to a flexible heating tube and vacuum system.To create a constant vacuum pressure used mobile vacuum tube filter device type vacuum mole” that moves around the interior of the plate in the shell - casing. The latter is made of water - and air-permeable heat-resistant material, for example high-strength polypropylene, which allows the pumping process through holes allotropes space with subsequent heat treatment by passing the coolant system Teplodar and heat treatment of concrete construction is solid floors can be immediately immediately demoulded, as the strength of concrete after these operations reaches 70% of design strength, the resistance decreases in 2-2,5 times, reduced shrinkage deformation, increases the resistance of the structure.The feature of this technology works is that you enter additional operation gradually pulling heat pipe connected to the vacuum system, corrugated permeable casing to create a permanent internal vacuum pressure in the casing and uniform vacuum throughout the area overlapping with the subsequent installation of a heat pipe in the casing to its original position and connecting it to the heating system with the aim of further heating the structure and strength of concrete.The essence of the proposed method is illustrated a device block diagram is shown in Fig.1, 2, 3, where we have introduced the following notation:1 - casing intermediate monolithic reinforced concrete floors;2 - welded reinforcement frame, to which the clamp is attached corrugated pipe casing of the heating system;3 - heat-resistant polymer-metal flexible heating tube that is placed in the casing; the dashed line shows a flexible hose heating motonaga polymer material (high strength polypropylene);5 - concrete mixture, fill the formwork;6 - air space between the shell and the pipe;7 - cap for pipe-casing, hermopolitan, providing sealing of the joint to create a vacuum;8 - valves and valves connecting joints;9 is a flexible (rubber) sealing cuff;10 - pull;11 - system degassing;12 - adapter to the vacuum system;13 - precipitator (cyclone) for water and sand;14 - vacuum pump;15 is a filter for the air released into the atmosphere.The principle of removal of excess moisture and air from the fresh concrete mix is illustrated in Fig.2.Corrugated tunnel-casing 4 in the closed volume between the cap 7 and the porous tube with the filter 10 in the vacuum creates a vacuum, water and air rushes through the hole of the vacuum device 9 into the heating pipe 3 connected to the vacuum system 11.So that the pressure in the system to maintain at a constant level, the tube 3 is moved is removed from the pipe-casing with velocity V. thus extracted pipe is disconnected from the vacuum system, and after evacuating the vacuum nozzle with filter 9-10 and plugs 7 are removed, and the heat pipe m is warm-situ design and rapid curing of concrete.Possible views of the loops of the heating system shown in Fig.4-6.Heat-resistant plastic pipes 3, enclosed in corrugated waterproof and breathable shell 4, is fastened to the reinforcing frame 2 with the same radius R, so that Assembly and disassembly of polymer pipes 3 were technologically quite simple and not time consuming.The pipe diameter, step and depth of laying, as well as the temperature of the coolant (hot water, steam, hot oil) are determined so that the temperature of the concrete mixture during the curing was maintained in the range of 55-60And during operation in the autumn-winter period the temperature of the ceiling accommodations was 40And floor 28-29C.The ceiling heating system is possible in the summer to use for cooling by circulating cold water in it. Floor heating systems are joined through a system of shut-off valves and valves at the inlet to the heat riser and outlet of fluid to the return riser.Effective use of the vacuum-concrete manifests itself in a high strength immediately after the formation of the product, in an intensive and accelerated hardening b is resursov when increasing the strength and quality of the final product, immediate partial or complete dismantling swietochowski designs.The quality of the vacuum concrete is influenced by the control system of the pumping process, as the sliding vacuum filter, placed on a movable flexible tube must continuously move on a fixed structure of waterproof and breathable shell and create a uniform pressure on all parts of the vacuum. The increase in the speed of movement of the rolling vacuum pipe leads to a sharp decrease in the vacuum in the concrete mix according to the thickness of the structure and reduce the effectiveness of the vacuum when removing a section of concrete from the vacuum tube. By reducing the moving speed of the vacuum filter as the vacuum improves with decreasing productivity. Therefore, the management process is to create the optimal zone of underpressure P:where Q=(Tof, Loc);Tof, Ku viscosity of water, the filtration coefficient and the coefficient of workability of concrete mixture, respectively;q - the quantity of water extracted per unit of time when the pressure P;r - pogum-tube;lin- distance traveled vacuum tube.When increasing the length of the perforated portion of the vacuum tube is a proportional increase in the speed of the extraction pipe vacuum.Thus, the proposed method and the device in comparison with prototypes and other technical solutions for a similar purpose allows to exclude from the process vacuum panels and traditional filters, simplify care for vacuum equipment, to reduce the energy consumption of the process, to reduce the duration of the evacuation, the hardening of the concrete and the finished product multi-purpose.The use of the heating tubes of heat-resistant polymeric materials as thermo-forming elements in a monolithic slab provides:- accelerating the turnover of formwork;- long service life due to corrosion of pipes;- eco-friendly - the absence of vegetation and Macedonia scale;- fast operation formwork systems as technological thermosetting formwork for monolithic fabrication of interfloor overlappings;- the ability to quickly enable this thermal system under the new regime of the building;- maintainability, the ability to conduct covert installation and dismantling of hot heating of the plastic pipes.- improving the quality, level of comfort and constructability, refusal unsightly, morally and physically obsolete elements hot water system;the reduced cost and shorter construction time.The use of waterproof and breathable membrane that is located between the heating pipes and concrete mixture, provides:- the possibility of reducing the water / cement ratio and increasing the amount of cement grout into the surface area of the concrete structure;- more dense concrete, which in the operation of buildings and structures slows down the process of carbonization, reduces the degree of permeability of chloride compounds and can withstand a large number of cycles of freezing - thawing;- improving the quality of the concrete surface after removal of the formwork the concrete surface has almost no sinks, it creates good adhesion when finishing tiles or plaster;- faster adhesion of the surface layer of concrete, which speeds up the beginning of the dismantling of the formwork;- ability Rmula inventions1.
