The invention relates to composite materials as a purely heat-insulating load-bearing and insulating bearing, including in the form of sound insulation and protective structures.
The aim of the invention is an inexpensive structural material of the available raw materials and waste in household and factory to the construction of low-rise buildings.
The level of technology
The production of advanced composites allows you to use a variety of technological processes in accordance with the generated patterns, to create a wide range of the best shaped structures by functionality, including multi-functional composites in construction. Existing composite materials, including "Sandwich panel" RF patent No. 62411 registered 10.04.07, are versatile building structural materials, mainly for warehouse and industrial buildings. Modern composite construction is on top of its progressive development and involves the multilayer structure: the main structural - layered carrier portion, puff peripheral insulation and cladding coatings. A variety of modifications of the construction of composites in the construction industry is created primarily n the existing analogues and in accordance with the function.
"Reinforced theprofile multilayer"
Construction reinforced multilayer theprofile, hereinafter referred to as "Monoprofile", structural building product and depending on the functional purpose, in contrast to the production of three-layer metal Sandwich panel with single-component insulation, made a variety of ways from a diverse array of building components, binders, reinforcing elements in the optimal number of stacked layered insulation in a single monolithic matrix frame and additional isothermal and thermal insulation in order to achieve cost-effective energy-efficient building materials.
By design and the materials used complex structures design theprofile composites are divided into main groups:
- flexible and soft: roll, industrial fabrics, sheets, tiles, extrusion, fiber, polymer, and others;
- hard: flat, rounded, profiles, trusses, beams, insulation, liquid, prefabricated, monolithic, masonry and other
The main elements of the design (see Figure 1): the carrier matrix in the form of monolithic sectional frame of Krasnodarskogo heterogeneous layered filler-insulator 7, heterogeneous reinforcing filler 2, RA is noparity heterogeneous multilayer insulation 3, facing the insulation - insulated inner 1 and outer space 4, the outer lining floor 5, crate 6. The formation of a properly designed combination Krasnodarskogo heterogeneous multilayer sectional insulator 7, equipped with a dissimilar filler 2 and heterogeneous multilayer insulation 3, allows to achieve the necessary efficiency of the supporting structure. The use of high-strength sections of the heat insulator 7 from thermoprofile, ceramics or pultruded fiberglass with effective heat insulation 3 on the outer contour of the bearing monoprofile dramatically reduces the consumption of material and dimensions of the products. Facing isothermal internal insulation 1 insulation is an important, and, if necessary, a flexible heat generating node monoprofile. Insulation, as thermopolyurethane, this layer 1 maximum support at the appropriate level the temperature of the internal environment. Built-in advanced isothermal heater 1 thermal heater with sensors control and regulation ensures stable temperature in a closed loop, and comfortable in a residential area. Facing thermal protective outer insulation 4 is a heat insulator, softening sharp temperature drops. Facing on which rite, as a rule, with insulated layers, designed for finishing of constructions inside and outside. Often these coatings decorative roll or sheet material is fully used as reinforcing elements. To avoid harmful condensation and mold on surfaces of the insulation categorically exclude large-scale use of polystyrene in the form of a foam. Cladding coatings sufficiently low permeability to qualitatively improve the indoor climate. Also due to this indoors, you receive the effect of the tree in winter and warm in cold weather, cool in summer heat.
The carrying capacity of the matrix increase with reinforcing fillers, especially at the edges due to high strength. The faces of this combination in a flexible and thin-walled composites completely lost in one whole. For flexible composites reinforcing filler perform fiberglass Mat, starlogot, fiberglass, mesh, fabric or filament basalt, linen, metal, etc. For hard - filler of the same above-mentioned components and dissimilar fittings, sheets, profiles, including thermal profile. Effective hardening is achieved when the content of 5-10% of the filler in the heat insulator.
Aggregate carrying monoprofile-based cement used concrete, foam concrete or cellular concrete is, hydraulic fine-dispersed adhesives with chemical additives, etc. In the production of insulating monoprofile as a binder is used, the corresponding liquid slurry of cement-lime or light concrete, weak sealants and adhesives, fixing, binders, etc.
Insulating and strength characteristics depending on the purpose of monoprofile regulate the method of selection and consideration of material properties of construction materials: moisture, water resistance, water absorption, exposure to shrinkage, melting point, particle size of the components of aggregates and their percentages, properties, binders, insulating layers and reinforcing fillers, as well as methods of manufacture. The smaller the pore size of the insulation, the weaker convection - air motion and the more efficient the heat shield. Properties depend not only on the physico-chemical properties of the components, but also on the strength of the relationships between them. Maximum strength is achieved if the between matrix and reinforcement, the formation of solid solutions or compounds. A comprehensive account of the degree of persoanele, insulation, and strength of materials allows you to create an optimal structure with the necessary number of layers energoeffektivnogo composite.

"A method of manufacturing a reinforced multilayer theprofile"
To achieve manufacturing Construction reinforced multilayer Technopolis", hereinafter referred to as "Monoprofile", the particular design is directly dependent on its load-bearing capacity and thermal insulation functions.
The structure of monoprofile, see Figure 1, form a reinforced bearing 2 bearing structural matrix - Krasnopolsky heterogeneous multilayer heat insulator 7, a multilayer reseparate insulating layer 3, facing the inner layer of the walls - insulated heater 1, the outer layer - thermal insulation 4 and the outer facing cover 5. Feature under the government of the bearing wall and integrated insulation-heat insulator 7 is when insufficient, less than 1000 kg/m3its density, if more than three floors, you will need additional reinforcement reinforcing fillers 2 or vozvedeniya special supporting frame of the building.
As reinforcing fillers 2 in order to enhance the strength of monoprofile apply metal, pultruded stekloplastovye rods, fibers of fiberglass, basaltoplastica, linen, fiberglass, etc. as a binder components used fusible components of the above products, foam glass, and vulcanizing sealing agents, hydrolytic lignin, cement and plaster mixes, etc. it is necessary to apply industrial or domestic gas installation for melting a separate reinforcing and binding components, mixing a profiling device for preparing mechanical mixture and forming Villeroy necessary reinforced profile of the produced composite. Depending on the purpose made composite products Repack or reinforce vapor permeable film (Izospan And Polypropylene VM 310), basalt or linen cloth, ceramic paper, Gidrotex membrane type, etc. as a cheap mechanical mixture, waste, recyclables and local natural resources: waste wood, plastic, and glass, ceramic watch, the sky and the concrete rubble of demolished buildings, the hydrolyzed lignin, scoria, tuff, pumice, mining, shale not more ⌀50 mm, sand, burnt clay (alumina), dry peat, polystyrene granules, crushed pieces of old tires ⌀10-20 mm or crumbs (powder) - modifier and other drugs.
As the cured filler used foam concrete, slag concrete, masonry, components, waste wood, Mat basalt, extruded polymers, mixes (crushed stone, slag, expanded clay), etc. In insulators insulators are plates OSB, ceramic paper, polyethylene foam, mineral wool and loose, such as slag granules of polystyrene, hollow ceramic balls, gravel, etc. are Made sectional-layered insulators porous or air separation medium. Advantageously apply the filler thermal insulator in the form of warm monolith (slag concrete, foam concrete) without the use of additional insulation, and even more economical as placeholders for secondary raw materials and recycling. Depending on the requirements composites astringent composition are cementing, polimerizuet, curing, sintering, adhesive, etc. and their components - glass, lignin, cement plaster, rubber, sealing medications
For the manufacture of monoprofile suitable well-known methods of construction, such as : size is% mixes the carrier matrix in a sealed form with all accessories in the monolith, clutches or the way of sandwiches. Apply for individual designs conopophila the conventional methods of spraying structures, foaming, extrusion, sintering the mixture and prokachivanija or extruding (pulling) profile cold or hot mixture through a forming die plate.
Apply the method of manufacturing conopophila at the place of destination for the erection of buildings and structures by building blanks and components dissimilar layers or method of Assembly (mount) components sitapaila layers on frame technology. Such methods produce "Termomeccanica monoprofile layer of any thickness, complexity, rotation, and density using insulating layers of polyurethane foam, sheet OSB, Magnalite, SOFTBOARD etc. with high thermal and strength characteristics. Progressive build houses on the base frame technology from the finished composite boards, panels and monoblocks "Termomeccanica" profile significantly advantageous in terms of speed of construction and cost savings. Frame technology simplifies the use and installation of separately prepared textured composites and combopanel on purpose, build phases, expand or rebuild areas (modules) of a dwelling house on the calculation of the family.
Due to the fact that oblits is VCE internal cavity walls-insulated heater 1, outer layer - thermal insulation 4 and the outer cladding coatings 5 require additional operations upon completion of the entire complex design monoprofile, typically performed separately. A comprehensive approach to accounting for the degree of persoanele, insulation, and strength of materials allows you to create an optimal structure with the necessary number of layers energoeffektivnogo of monoprofile.

Scope and benefits "TC of Monoprofile"
"TK Monoprofile" as building materials, heat-and sound-insulated, load-bearing and non-bearing structures can be used in the construction of roads, industrial containers and coolers, sports, commercial, industrial buildings and constructions, residential cars, engines, and houses and other
A well-established manufacture of reinforced Monopropylene boards, panels, mono and other composite products homemade or factory can significantly increase the quality, standardized and industrialized housing. Its production allows to recycle plastic, glass bottles and other containers, tires, slag, ceramics and other industrial waste wood, ceramics, glass, hydrolytic lignin, slag, mine workings and other, secondary use of crushed ceramic and concrete building materials during demolition, and PR is the use of recycled and local cheap natural resources.
The construction of a wall in frame technology recently demonstrated high technical and operational characteristics, as well as advanced architectural solutions. Frame technology better than others meet the power structure of the wood, "Pultruded fiberglass" and "Thermoprofile". This technology is economical, functional and all the parameters exceeds current and ensures the durability of new pre-fabricated buildings. Progressive build houses on the base frame technology from the finished composite boards, panels and monoblocks "Termomeccanica" profile significantly advantageous in terms of speed of construction and cost savings. Frame technology simplifies the use and installation of separately prepared textured composites and combopanel on purpose, build phases, expand or rebuild areas (modules) of a dwelling house on the calculation of the family.
Monoprofile strongly reminiscent of practical three-layer wall blocks (polyblock) 400×400×190 mm (22 kg) with high thermal insulation R 3,65 m2°C/W and the density 1600-1900 kg/m3. The unit consists of a supporting layer 160 mm claydite-concrete M200, 160 mm inner polystyrene foam 25 kg/m3and 80 mm outer layer of claydite-concrete M200 with facial decoration. All 3 layers bonded together basalt-plastic flexible links is Alain". The wall of such polyblock does not require textured cladding and more economical than other material. Also significantly reduced the duration of construction from conventional masonry (Use). L. No. 4).
Significant disadvantages of poliblog: the risk of mould growth on polystyrene and indoors; when burning the allocation of carbon monoxide and dangerous product of the cleavage of the benzene nucleus. Even in normal mapping Monoprofile has advantages over a polyblock: characteristics - higher strength and thermal insulation due to the considerably large size products, great perspective on unification of products, efficiency of production in order wide recycling progressiveness in the technology of prefabricated houses and their reconstruction, seismic resistance, etc.
The use of Monoprofile for insulation and fencing of buildings and structures greatly simplifies construction, reduces the total weight of the structures is at least 2 times, reduce the consumption of expensive insulation, wall and other structural materials, expanding the architectural possibilities, improves the design and comfort indoors and saves money. Energy saving modern models of individual houses from "TC monopropylene" structures and parts cost 5-10 thousand rubles per square meter dilploma and you can build almost manually without heavy equipment.
Obvious advantages of Comparatie over traditional materials: superior thermal properties, low specific weight, wide adjustable range given the heat resistance, earthquake resistance, low cost, unification, practical in application, etc.
The prospects. The widespread use of Monoprofile limited (constrained) due to lack of cheap special reinforcing elements, and is also available binders, additives and medicines bonding, gluing, sintering, polimerizuet, cement aggregates, etc. for Example, at present the difficulty of applying the binding of lignin (a natural polymer) from the industrial hydrolysis of waste in a huge number that thermal decomposition ligninase binding components occurs at 300-310°C and for this purpose it is necessary to use a compact dual-fuel boilers. This is again a rise in the cost of works in the manufacture of the panel and large, monolithic or bornology fencing. But all this is completely solved questions, allowing wider application of Monoprofile without reinforcement reinforcing elements.
Time actively to implement the construction of luxury and cheap pre-fabricated "TC monopropylene" houses.
