Log houses. This traditional design in which the walls are made of solid wood. Ecological properties of high building. Shrinkage of the wall elements is significant because of reduced moisture content of wood walls and seal the cushioning material in the operation.

Ecological properties of high building. Shrinkage of the wall elements is significant because of reduced moisture content of wood walls and seal the cushioning material in the operation. The possibility of diversity of architectural decisions - at the level of traditional folk architecture. House of sawn timber. The walls are made of sawn lumber square or rectangular shape, followed by a decorative exterior and interior panels. Moisture content is not standardized. As the cushioning material is most often used flax tow. Warping lumber for shrinkage leads to an increase mezhventsovyh gaps, cracking on the lateral surfaces, and distorted the whole building. These buildings were used in suburban and even in residential construction. Perspective of their market is highly questionable - relative cheapness, the external simplicity and accessibility of technology turns low-maintenance properties. Attempts to improve the properties are necessary to use designs and technologies that meet the more expensive and high-quality proposals. Home of the planed profiled solid wood with natural humidity. Cylindrical shape of elements (from cylinder beams) or close to rectangular (a profiled bar). Humidity wall elements is not standardized. In the factory is treated as a minimum - a profile as a maximum - all the constructive elements of the wall material - longitudinal grooves, cups, the end faces, end slots shkantovye openings, compensation grooves. The presence of end slots provides the ability to install millwork without elaboration openings. The presence of compensatory grooves reduces but does not preclude the formation of cracks on the sides. Environmental properties of homes high. Shrinkage of the elements in the walls of a large, main component of shrinkage - reducing the size of timber wall material during drying. The sudden change in humidity, for example, due to intensive high-temperature heat your home, there is a warping and cracking of elements increased in the walls. Timber framed items are generally more prone strains poslemontazhnym than cylindered. Antiseptirovanie surface coatings used by some companies as a final operation of the plant process technology manufacturing building elements, and the effectiveness of coverage is reduced due to high moisture content of wood at the time of the coating. The possibility of diversity of architectural decisions is higher than in the technology chopped homes. Properties of homes in general call the comments of customers because of cracks on the sides of the wall elements increases as the drying timber wall material, a relatively high roughness of internal surfaces, the torsional deformation of wall elements and, consequently, a large mezhvenechnoy breathability, non-uniform shrinkage of the exterior and interior walls . Currently, the trade group the most numerous in the number of proposals, among other types of wooden houses, in the long term, its share will decrease. Home of the planed profiled solid wood normalized humidity. Form elements - close to the cylindrical or rectangular (square log). Humidity Walling before finishing profile processing - usually 22 + / - 2%, which corresponds to the standard SFS Finland 4895. In factory processing is performed on all surfaces of wall elements and antiseptprovanie, whose efficiency is quite high. The use of protective transport packaging is mandatory. As the cushioning material is commonly used polypropylene tape. When installing apply a contraction of hairpin wall elements, as well as maintenance work in the initial period of operation. Since mid 90-ies of Finnish companies and their dealers offer very difficult to form profiles of wall material. A variety of architectural solutions far exceeds supply for other types of bulk wall material - but not because of the peculiarities of the material, but because of the greater experience of companies who have mastered the technology. Properties of buildings compared to other product offerings from solid wood - the best in all respects. Are retained, although reduced quantitatively, some inherent drawbacks log: shrinkage of the walls during operation, uneven shrinkage of the outer and inner walls, cracks on the sides. In the near future the number of proposals for this commodity group increased, improved quality characteristics of the proposals of domestic manufacturers and their dealers. House from glued wood. The shape of profiles and main process operations have slight differences from the houses of solid wood normalized humidity. In this case, the location and shape of the lamellae (the individual elements forming the glued wooden logs template for subsequent profiling) are different for different firms - manufacturers. Increasingly used vertical location of adhesive joints. The level of humidity and surface roughness of side wall surfaces of the elements close to the furniture - that is, have a moisture content of about 10%. Shrinkage of the wall elements in the walls is minimal - mostly due to compression of cushioning material. Cracking on the sides is completely absent. Environmental properties are comparable with buildings made of solid wood normalized humidity. Antiseptirovanie in factory conditions, protective packaging, compliance with high demands on the transportation and storage - necessary elements of the technology of houses from glued wood. The use of such technologies is typical for companies with high production standards, while often the same model of developed homes are offered by firms in the performance of solid wood normalized humidity and glued Walling. The share offers houses with walls made of laminated wood of the total number of offerings on the market of wooden houses still small, but in the coming years will increase. Home of the planed profiled solid wood normalized humidity with additional thermal insulation. A small number of such proposals appeared in the commodity market as a response to the construction industry to increase the regulatory requirements for thermal resistance of the wall construction. In this task of improving the thermal characteristics was solved by the price appreciation of design due to the growth of material elements, complexity of manufacturing and installation, as well as the emergence of new defects due to a combination of shrinkage and dimensionally stable elements in a single wall construction. Adoption of the Moscow Region Territorial building standards for thermal protection of civilian buildings sozdlo legal basis for structural optimization of the entire building as a whole, which may limit the growth of sales of this type of houses. Houses made of construction of "sandwich". Distinguish self-frame houses, in which the frame is made of regularly spaced pillars, connected by horizontal and oblique connections, and panel, whose walls are made of different size wooden panels, assemble the panels usually have a crane. The gaps between the posts are filled with thermal insulation, exterior and interior surfaces are faced with different materials. The design of relatively inexpensive, Non-shrinking, with great potential use of various building materials and architectural solutions to ensure that regulatory requirements for the thermal resistance of walls. But visually, it usually is not made of wood, the longer section log. With regard to other properties - they combine to provide such structures stable distribution. The share of such structures in the total number of proposals wooden buildings remain approximately constant, more likely in the coming years, a slight increase. Houses made with elements of imitation log house from solid wood. The walls of houses in the form of a skeleton with insulation, with interior and exterior cladding are made of wooden elements, the visible side of which is outwardly similar to the lateral surface of the log house from solid wood. The corners are racks of simulation glued elements, which form the collection coincides with the appearance of the corner of a log house with walls made of solid wood. Such designs have appeared in the Moscow construction market no earlier than 1996. Structure as a whole has all the advantages of frame structures "sandwich": the required thermal properties, the lack of shrinkage, the technological ability to use different finishing materials on the premises with special conditions - wet, with high temperatures, with the appearance of the log construction meets the highest requirements the properties of the decoration - the absence of cracks on the sides and a small roughness on the displacement of half the height of cladding elements in mutually intersecting walls. Currently, the number of proposals for this commodity group is negligible. Source: Stroyportal.ru
