Anyone who has ventured into one of the most important affairs in his life - build your own house (cottage or permanent residence), first thinks about what material will be erected bearing walls - the basis of comfort, reliability and durability of the future dwellings. After all, wants to build a house with a capital letter - a durable and beautiful, which would be warm and comfortable, which always want to come back - and a frosty winter, anyone who ventured into one of the most important affairs in his life - build your own house (or cottage for permanent residence), first thinks about what material will be erected bearing walls - the basis of comfort, reliability and durability of future homes. After all, wants to build a house with a capital letter - a durable and beautiful, which would be warm and comfortable, which always want to come back - and a frosty winter and hot summer evening, the House, who will be jealous neighbors and friends who will admire; House that even after 100 years it will be durable, comfortable, modern and will provide us, our children and grandchildren a comfortable life at minimal cost to its operation. Thus fully meets the requirements of a house built on the "Izod". The technology of "Izod" put the construction of bearing walls of reinforced concrete with Captive formwork construction of a special foam. On the main parameters, such as thermal protection, sound insulation, comfort, ease and speed of construction, strength and durability, the technology "Izod" refers to high technology in construction. The system is not experimental. In its implementation shall apply the materials, design and technological solutions that have passed long and thorough review. Polystyrene foam was opened in 1951 in Germany and immediately began to be used as a thermal insulator for covering the exterior walls of buildings. A little later, was developed and a corresponding system of coverings - Polymer "plaster." In the late fifties was possible on the basis of accumulated experience and theoretical calculations suggest rightly that material to the general public involved in construction. In the early sixties, one Austrian engineer got the idea to replace the method of building walls, followed by pasting their foam polystyrene plates for the manufacture of formwork of polystyrene foam in the form of blocks, and then assembling them on the spot and fills them in concrete. The result is the same, but labor costs are much lower and, consequently, it is economically more profitable. Since then, the polystyrene blocks are continually upgraded and now provides a firm and comfortable design, with which to erect a building of almost any architecture. These technologies are applied in Western Europe, Australia, Canada and the USA. Elements of the Captive formwork "Izod", made of a rigid self-extinguishing polystyrene in the form of hollow blocks, reinforced and filled with concrete, is a universal system for walls of objects of any type. Special design lock prevents leakage of concrete and allows you to quickly and accurately connect the blocks like an assembly of cubes in the popular children's game "Lego." This design allows to achieve an optimum combination of physical, mechanical, heat and Accompanying sound characteristics of the structure. Polutorametrovy blocks virtually weightless and easy to raise a child. During a manufacturing operation under construction is solid concrete wall, framed by the inner and outer sides of heat and sound insulating sheath of EPS. You will immediately receive a warm home in a surprisingly short time. The rate of construction of walls such that the two men for three days can build a house usable area of ??100 square meters! To better understand the benefits of "Izod" refer to the following examples. Bearing wall can be isolated on one side, with two sides or not at all isolated. If the wall is completed without additional coatings, the wall material must meet all its demands in terms of carrying capacity, sound and heat insulation. In order that the wall retains heat well and does not permit the sound, it must be porous. But it will suffer its static properties, ie wall does not bear heavy loads. In order to increase the strength of the wall, you should reduce the number of pores, which leads to loss of heat-shielding properties. For the same, to keep both, you can increase the thickness of the walls. But this leads to wastage of materials. If the wall is covered with a layer of insulation, such as polystyrene foam, then in this case it will possess excellent static, heat and sound insulating properties. And if the bearing wall insulated on both sides, we get the unique characteristics of sandwich. Now we come to the point of heat-technology "Izod". Layer of polystyrene 5 cm thick has the same thermal conductivity as well as the concrete wall thickness of 2.5 m. In addition, double insulation ensures minimum variations in temperature of the bearing wall. Therefore, all elements of the building will be protected from thermal expansion and as a result - from the appearance of cracks. In addition, the wall was built on the "Izod" very responsive to changes in temperature inside the room as opposed to single-layer walls with insulation or no insulation in which a significant portion of the heat expended on heating the environment. When these walls are cooled by a sharp change in temperature, to heat the air in the room, you first need a long time to warm up the wall. PARAMETERS OF WALLS "Izod" wall thickness - 25 cm of them: 10 cm - Polystyrene, 15 cm - concrete (series Zomsom and 35MSO wall -30 and 35 cm of them: 15 and 20 cm and 15 cm expanded polystyrene concrete, respectively). The thickness of the concrete in the series of MCP depends on the size of removable bridges (optional jumpers are made of any size). Weight walls without finishing the external and internal - 280-300 kg / m 2. Consumption of concrete - about 125 l / m 2 wall. Coefficient of thermal conductivity blocks: Lo = 0.036 W / mK for Zone A and A 0 = 0,044 W / mK for the area within fire walls -1 degree. Water vapor permeability - 0.032 mgDm.ch.Pa. Water absorption for 24 hours,% by volume - 0.1. Acoustic insulation - 46 dB. Tolerance for objects up to 25 m. Can be used in seismic areas. Materials used in building the system "Izod-2000 uses a special construction polystyrene (imported). The density of polystyrene in the building elements ranging from 25 to 27 kg/m3. Expanded polystyrene is environmentally friendly material (97% air and 3% stuff) and even used for food packaging. Polystyrene foam almost does not absorb moisture (moisture pogloschenieO, 1%) and intensity of the transmitted water vapor (water vapor permeability - 0.032 mg / m.ch.Pa) contained in the air. Low temperatures have no effect on the chemical and physical properties of polystyrene foam. At positive temperatures to 90 ° C, polystyrene does not alter their parameters, even with prolonged exposure. High density polystyrene, as well as special design locks connecting the building blocks of "Izod-2000, eliminates the violation of the heat units, both during installation and during operation of the building. Atmospheric influence the outer walls of the polystyrene blocks is practically not affected. Expanded Polystyrene is the material self-extinguishing. In case of fire it does not spread flames and does not emit toxic chemicals. In addition, the concrete structure that provides the carrying capacity of the wall "Izod" is non-combustible material. If the polystyrene is exposed to flame a short-term, it is melted around the fire source, but does not ignite and, accordingly, the fire does not spread. Nevertheless, it can vozgoretsya prolonged exposure to flame, speed and progress of fire on its surface is very weak. If you remove the outer flame, the combustion of polystyrene foam is immediately terminated and is not observed afterglow. Expanded polystyrene does not burn completely, if not the direct effects of other, more combustible material such as wood, wool, paper, etc. If the EPS was stored for a long time, its flammability and flame propagation speed is reduced to such an extent that blocks derived from it, with fire behaving well for hard inflammable materials. Unlike other building materials, styrofoam is not radioactive. Expanded polystyrene does not contain substances that feed the microorganisms. On years of experience in the construction of buildings on this technology in Europe, polystyrene is not affected by the destructive impact of rodents, mildew, fungi and bacteria. Expert's Advice Installation bearing walls on the "Izod 2000" is not difficult and is available even unprofessional. Polystyrene packing blocks begin to carefully leveled in the horizontal arrangement with the foundation waterproofing. Insulating layer can be made of double layer of roofing material in the mastic or polyethylene film. The first series of polystyrene foam blocks are placed directly on the waterproofing layer around the perimeter of the future building, passing through the cavity blocks fastened to the foundation of the vertical rebar. Then, in accordance with the project at home, in the grooves of blocks lay horizontal reinforcement rods. During the laying of the first row is formed architecture of the whole floor, so it is important to immediately draw in the right places slopes of doorways and challenges of internal walls. The second layer of blocks should overlap the vertical joints of the first layer on the principle of brickwork with a shift in multiples of 250 mm (Series 25MSO), which allows tightly fix the form of the structure. The compound blocks of polystyrene by light pressure on their edges, to locks, which are at the top and bottom edges of the locked tightly without gaps. Third row - check for alignment of the layers of blocks along the vertical joints of masonry. After checking with the project size walls and axial accuracy, should be muted by the elements of OM and OH all the holes in the side blocks formed at the connection at the wall corners and openings, doors and windows. It is also important to establish in this series of temporary tightening of the jumper blocks MP for fixing the size of openings. In addition, the jumper of the opening must be protected from subsidence and the potential collapse under the weight of the liquid concrete by means of vertical struts, which are removed after hardening of concrete. Jet concrete must first be directed to the corners of buildings, branching walls, slopes and edges of the holes, and only then at the middle of the cavity wall. Seal concrete shall shtykovaniem. When laying fresh concrete more than 6 hours after the previous tabs need to clean the surface of hardened concrete from the vitreous laitance and moisten it. For better grip surface layers laid concrete do not need to flatten. For registration of joint external and internal walls and corners of buildings should be cut away pieces of the side walls of some units in the IVS and the face of the other so that openings can be formed to miss rebar and concrete mass in the straight or on the corners would form a strong connection . Since the sealed casing "Izod" restricts the removal of excess water, to control its content in the concrete mix. If necessary, the plastic consistency of the concrete can be achieved by adding plasticizers. If you intend to build on the "Izod" wall basement or cellar, it is necessary to protect the outer layer of polystyrene from the lateral earth pressure. External waterproofing basements walls is usually carried out in the traditional way, as and when the masonry walls of brick. Archways are made up of blocks to dry. " Then cut out the contour of the desired arch, the lower part girded with sheet metal or other material that serve as a removable formwork archways. Reinforcement and concreting of arch bridges in the same way as flat lintels of doors and windows. If necessary, the lower part of the arch can be insulated with polystyrene foam sheet. After performing the above operations can begin to fill the voids with concrete blocks. When an individual building to better implement the concreting of two - three rows, concrete or concrete mass, cooked on site. Grade of concrete shall comply with the project. In the process of concreting every two rows of the upper edge of the wall must consist of a number is not filled in this cycle of building blocks that serve as a screed. Additionally, the upper edge of the number of blocks should be protected by proofreaders MN, so that locks do not hit the concrete mass. These correctors can be used repeatedly. After the first two rows of blocks are laid and concreted the following series, etc., grow in a spiral walls of a new home. During the construction of a multistory building blocks conveniently fill the cavity with concrete pump, adjusting the flow of concrete so as not to exceed the volume of 10-15 m3 per hour (if the consistency of the mass is plastic!). Technology "Izod" allows you to use the various options floor. Overlap can be made of wood, of cast or precast concrete. The choice of type of overlap is determined by the building project. If the project structure is not bearing joists, the completion of the structure can be designed with the help of blocks used for mounting holes, cut a hole in its bottom so as to integrally connect with the wall below. Another frequently used option of overlap can serve as a ceiling of reinforced concrete, made on a sheet of corrugated board. This kind of overlap can be easily installed on site without the use of sophisticated construction equipment and can be easily adapted to meet project requirements for strength, heat and sound insulation by additional reinforcement and stacking layers of insulation. Selecting the type and shape of the roof and cover it depends on the project structure. Technology "Izod" allows for a variety of roof structures with virtually no restrictions. Technology "Izod" allows different versions of the external and internal finishes: it's front panel, and polymer plaster, and siding made of vinyl or metal, and the most common facing materials such as plaster, brick, tile, stone. In this case, no additional wall preparation is required - ideally flat surface of polystyrene. Summing up the communication is solved as easily: in a porous material is easy to make groove at all necessary wiring and supply system. CONCLUSION So, what gives developers the technology "Izod"? Reduced construction time, as one of the main indicators of return on capital investments. Using traditional materials home construction stretches over the years. It is known that labor costs for the construction of one square meter of brick walls are an average of 4.33 hours. If, however, build on the "Izod", the same area of ??the wall being built less than 0.43 working hours, that is 10 times faster! In addition, labor costs, construction is about 60% less than in the construction of the walls of the traditional brick. Savings on the cost of wall materials. Cost of 1 square meter of wall "Izod" about 30% below the cost of brick walls. Simplicity of the work. Having the desire and some skill, you can build a house on their own and preserve their assets. Savings in the construction of foundations, as the walls "Izod" create much less stress on the foundation in comparison with any other wall materials. Benefit from more useful area, since the thickness of the walls "Izod" only 25-35 cm - is incomparably smaller than the thickness of walls of other construction materials for the same heat-capacity. Ease of installation and installation of sewer, water pipes, electrical wiring and as a result, savings in these studies. High thermal performance of walls - this is the only way to avoid the high cost of purchasing individual expensive heating equipment, transportation, fuel, time and labor for its operation. The cost of heating the building, "Izod" compared to the brick will be in 3-3,5 times less. Lower transport costs. In comparison to traditional brick transportation costs polystyrene hollow block is 3-4 times lower. Source: Portal Vashdom.ru
