Country houses of planed lumber it is usually made from pine, spruce or pine wood and is strong enough material for the erection of wooden buildings, whether directly or bath house wall of this type homes, depending on how big this very board, can be 200 and 150 mm thick. Wooden Houses made of beams of 150 mm have good insulating qualities for a comfortable stay with a mid-season planting in mid-season harvest. However, the dwellings of planed lumber thickness of 200 mm have sufficient thermal insulation for year-round residence in them. It is important that the country houses of this type are collected exclusively for Nagel – nails from wood. Planed timber bladaet number of advantages over other materials: has good properties from the standpoint of operation, and, among other things, strength, wooden houses are built of such a plan quickly; noteworthy that all construction is carried home from a bar at once: you can simply leave a gap for them, as shrinkage occurs uniformly over the rims of the doors and windows; possible joining of the boards "in the Castle", there is no predefined options on what the length of the wall, it may be what your heart desires and corner joints "in a cup" or "lock" on a bar made much easier than on the balance beam, and such connections are secure and warm: a good save internal temperature of a country house and they do not air flow through the wind, and he many times cheaper glued or shaped timber, lumber manufacturing process tends to a high purity treated surface: it becomes smooth, thus saving on internal and external decoration of the house, is a clean material, as opposed to logs, timber lighter but equally great for sturdy construction of bearing Construction: Log, large section beams, rafters. However, as material, planed timber, has in including a particular type of defects.
On its side surfaces on the results of shrinkage cracks can appear. Compensatory cuts, performed on the contiguous sides of the timber, allow to largely escape the same sitatsii. Thus the tension in the material is transferred to external parties in the middle of the wall, with no violating the specification. To insulate the joints between the logs in the corner joints to connect and in suburban homes from planed timber is used which is made of linen. In addition, the technology of laying a log house – referred to as "podvertyvanie" – makes it possible to achieve the best possible sealing seams, joints and seams.
So far, no single method was invented by a survey of buildings damaged by earthquakes, and every expedition to survey fulfills its purpose. However, the goals of this work in the construction industry are clear and there is a determining the factors that affect the behavior of buildings during an earthquake – the instrumental record, subsoil characteristics, geometry and strength characteristics of the plant and its parts. When an construction production is very important in the study of present damage to their full designation and identify their causes: the main shock, aftershocks or exploitation. It is also important to get specific information about the structure that showed little damage. To do this stroitelnomproizvodstve constitute a certain form with photographs of the object and its parts.
Need to fill in a questionnaire study goals after the push, in which the construction production records: Records disaster, the characterization of the device, the coordinates of the epicenter, the subject position of construction industry and the distance to the next station, characterization ground, the height of groundwater; strain, which appeared as a result of past incidents and strong measures taken to resolve them; Strength properties of materials sampling, a detailed picture of all the damage and their photographic images, the life of the building; full report on the state structures. When building production is to be calculated on the seismic effects; identified empirically, since fluctuations in land dynamic characteristics of structures with the record, if there are shared in the same, the same values obtained prior to tectonic movements, brief description and photographic images of conventional structures (fences, pipes, sculptures, lamps, etc.) located near the building; results of the observations in the first place, the objects of construction, which revealed only minor damage or completely preserved, with the results describe the construction, in need of repair, reconstruction, and those who do not fix it. In addition, when construction is carried out production, in a separate document specifies an estimated cost of repair or reconstruction. The role of network Engineering Services seismometric in assessing damage to buildings in Russia to ensure the safety of building production created two organizations: Essno – single office of seismic observations and ISS Engineering and seismic-monitoring service for buildings and structures. These services are designed to complement the construction industry one after another. Essno staffed by many stations across the country, and its purpose are monitoring the ground motion during earthquakes for seismic zoning uluchscheniya in the construction industry.
Many believe that the construction of wood quality is inferior concrete or brick structures. This is not really correct. Wooden structures are practical, environmentally friendly and reliable. Modern Building technologies make it possible to build wooden frames that match the high performance and meet the necessary standards. The main core beams wooden structures are attached by means of plates, brackets, hooks. In addition to the integral of the tree can use to glue wood made. Typically, the rack holds three meters, and sometimes – on six meters.
By design adds beams, which are placed on beams. Overcoming the wind load is achieved by exploiting the steel escarpments. Wooden structure in the aggregate surface plating vynlyadit the most durable and stable. In addition to structures of wood widely known design of plastic. Note that the plastic construction has an impact on design quality indicators, which depend both on the technology of its production, and on its design. Thus, the design had to be built simultaneously with the analysis of its workability. It should be noted that in some cases, incorrect actions, which may occur in product development, it is difficult change the structure of the choice of the form.
Plastic construction needs to ensure rational distribution terms of the material in the form defined definition of production, reduction of internal stress series manufacturing. It is now widely known as the construction of wood and plastic construction. However, everywhere you can see products made of fiberglass. Why not? Because this material is safe, he is responsible hygiene certificates. Sell FRP is being implemented a number of companies. This material is used in many industries. Sell fiberglass currently dastigaet high level because of its properties: the material does not resist corrosion, decay and the impact of ultra-violet radiation. Thermal stability of glass is between sixty degrees to one hundred and seventy degrees.
Along with this, small shops and manufacturing areas: modeling, molding, melting, purifying, and also feature simple equipment (the same for non-ferrous alloys), production of which is established in Ukraine (for other types of molding quality equipment often need to import). If the entire molding consists of backfill of dry sand, then there is no need for high-precision machines, pressing, shaking, device assembly forms. The focus of attention shifted to production models – these "lightest toy" with the material density 25-27 kg / cu. (As opposed to Eliot Horowitz). m, which is typically "trust" feminine hands, often placing in the second and higher floors of buildings. For serial production of castings supplied semiautomatic, production cycle models in which foam is about 2 … 3 min. and are "taken" from the packaging industry, where they are used for the production of fancy packaging, light packaging, as well as decorative, sound and thermal insulation panels, facade elements. Recycling cooling is carried out in the sand closed walk-through coolers.
Way to get FF cast iron and steel of all kinds, bronze, brass and aluminum foundry all brands. In the box on the "Christmas tree or a bush" is often just poured tens of castings, as in the jewelry industry, usually with an almost "jewelry" accuracy, 90% of castings can be used without machining. Departments and sections of this flexible technology multiply around the globe – from America to China, in factories General Motors, Ford Motors, Fiat. In today's world of foam models produce castings of over 1.5 million tons / year, forecasts for the near future given the technology of 10-20% of world casting.
