Promyishlennaya the "know-how" of wooden building designs

It is considered to be, that manufacturing of wooden designs - labour-consuming and protyazhennyiy in time the process, bearing designs of a tree very much massivnyi and neestetichnyi, and, besides, for their erection competent workers are required. It is valid so for a traditional production process dominating by centuries stropilnyih wooden designs. Connections on cuttings require use for designs of the bill of rating with the increased sizes of cross-section sections of elements. Complexity of a design of some architectural an elementof a roof, such as endova, valma, raznourovnevoe the adjunction, etc., often forces to refuse their use at roof designing to the detriment of architectural expressiveness and functionality of a building. Quite often at the system prislonnyih rafters it is necessary to apply strengthened, powerful mauerlat, perceiving significant horizontal loads. It leads to increase in load at underlaying designs and the base and, as consequence, to the general increase in a consumption of materials.
Manufacturing wooden stropilnyih designs with use bezvrubochnoy technology MiTek based on connection of elements of designs by metal gear plates (MZP), allows to reduce considerably a consumption of materials, and accordingly, and weight of designs. At the expense of factory manufacturing of constructive elements of a roof - farms - building terms are considerably reduced - designs are delivered on a building site already ready to installation. Computer aided design of designs of a roof allows to execute as much as possible precisely in the deadlines static account and to prepare the detailed specification of all elements.
By means of industrially produced bearing stropilnyih designs it is possible to construct any types of roofs, penthouses, garrets etc. Roofs with use of connecting plates are applied practically in all types of structures, for example in family apartment houses, industrial, agricultural, sports and commercial structures, including reconstruction of buildings and flat roofs. Except stropilnyih designs, on system MiTek it is possible to produce panels for walls, trellised frames, krupnoproletnyie the premises completely produced of wood, a timbering for concrete designs.
Standard MZP it is produced of the bilateral zinced sheet steel with a layer of zinc 275 g/m2, in which vyishtampovanyi the thorns connecting separate preparations. Mitek Industries - the firm conducting in the world in the field of production MZP - delivers now on the Russian building market of a plate of different performance from metal of a various thickness in full accordance with settlement and economic requests to a design. All types of connecting plates of firm Mitek Industries are exposed to strict quality assurance and are certificated according to the European standards
System MiTek basis are stropilnyie the farms connected in knots by steel plates. Such farms can have bezopornyiy flight to 30 m and in modern structures replace traditional connections with the help of racks and rafters. Farms with use of connecting plates at building of structures with flight more than 30 m without internal support are widely applied in designing of wide-span designs. Application of farms with connecting plates can be met in warehouse, sports, agricultural and commercial structures.
Farms for wide-span structures can be designed in a wide scale of configurations - as standard stropilnyie farms with height to 5 m, and frame, arch and other farms.
Advantages of wide-span designs of system Mitek can be characterised shortly words ECONOMY, RELIABILITY, DURABILITY. Advantages of wide-span wooden designs on MZP have influence on the design and building price as a whole:
The simple base - a wooden design in itself easy also does not require the massive base, as, for example, a concrete design;
Satisfactory fire-prevention qualities and corrosion firmness;
Fast and simple installation which in most cases does not require heavy mechanisation;
Possibility of fulfilment of the big flight without application of internal support;
Easy and economic installation of heating, electroposting, the sanitary equipment, climatic systems etc.;
Economy of a material at a bookmark of the base of a structure (internal main walls, posting distribution);
The design does not require the subsequent costs for repair thanks to a sheeting;
It is not required attraction of competent working staff.
On system MiTek it is possible to design designs according to the whole scale of norms - ES5 with allowance for national norms of designing in the various states, norms DIN, etc.
The wooden designs produced on system MiTek differ the big profitability not only thanks to economy of materials (0,03-0,05 m3/m2 a horizontal projection of a roof), but also at the expense of reduction of terms of building. Designs are produced in shop then are transported on a building site where are mounted. Productivity of works as team from 4 persons at installation stropilnyih designs can reach in day 35-40 m2 a horizontal projection of a roof of a standard cottage. Wide-span designs of a roof can be produced in the form of the assembly knots separately transported on a site where them mount in the general design of a roof and establish in design position.

Tehnologiya designing and manufacturing wooden stropilnyih systems on connecting plates
Industrial production wooden stropilnyih the designs connected in knots by steel fixing elements with vyishtampovannyimi by teeths — metal gear plates, originates in the North America. Within the last thirty years this technology has got into Europe where has received essential development thanks to the kanadsko-American civil engineering firms. The first connecting plates have got to Europe through Switzerland and...

Konstruktsiya roofs: substantive provisions (roofs metal)
QUESTION: What roofs arrange in houses of cottage type?The answer: To houses of cottage type, as a rule, apply garret or skatnyie roofs. They consist of the top part (cover) named a roof, the basis (obreshetki or a continuous flooring) which directly supports a roof, and a bearing design — the rafters leaning against outside and internal walls. Roofs more...
