On Fig - the building envelope top view.

Wooden prefabricated element represents a product 1, which is two long longitudinal parts 2, which are arranged in parallel at a given distance from each other in plan and interconnected embedded links 3 with the formation of through voids 4 (figure 2). Vertical longitudinal parts 2 and mortgages due 3 made of quality wood humidity 10-12% primarily of lumber in Board, timber, etc. Manufacture of longitudinal parts, preferably from standard trim boards with a minimum width of 150 mm

On the inner surface 5 of each of the longitudinal parts facing the mortgage ties in the middle and cut a groove 6 having a rectangular cross-section.

Great fitting groove 7, which is its height h parallel to the inner surface 5 of the longitudinal parts 2 and its lower side 8, the length of which corresponds to the depth of the groove 5, are perpendicular to the surface 5.

The grooves 6 are arranged on the two longitudinal parts 2 and their Central transverse axis y-y coincide with the Central transverse axis of the structure Y-Y, so that the top and bottom inner surfaces of the longitudinal parts are formed symmetrically spaced lugs 9 and 10.

Each groove 6 is cut continuously along the entire length of the inner surface of the longitudinal parts, i.e. the length of the groove 6 is equal to the length of the longitudinal parts 2.

Mortgage connection 3 is inserted in the opposite location is military grooves 6 discretely along the entire length of prefabricated wooden element.

The distance between the longitudinal parts 2 and the distance between mortgage bonds 3 choose depending on existing efforts in the design and using design as a wall cladding additionally taking into account thermal requirements.

The location of the embedded links 3 in the longitudinal grooves 6 in the manufacturing process design is fixed only by the width of the longitudinal groove 6. In the longitudinal direction of the collecting element embedded links, due to the implementation of grooves in the longitudinal parts are continuous along the entire length, can be installed at any distance, given a module and a calculation that makes prefabricated element is uniform.

Taking into account the manufacturing tolerances of precast element height fixtures corresponds to the width of the groove.

The width of the groove h, which determines the width and cross-sectional mortgage connection 3, is installed in the groove, significantly (several times) exceeds its depth and δ is 0.4 to 0.7 of the width of the longitudinal parts 2.

This ratio is determined experimentally and the deviation from the specified ratio in the lower side may lead to loss of bearing capacity of the precast element, and in a big way to waste of material.

By increasing the cross-sectional precast element enhances his mouth is echeveste and improve thermal performance.

In the manufacture of wooden prefabricated element fiber longitudinal parts must be oriented along and fibers embedded links are oriented transversely to the longitudinal axis of the precast element that increases the strength of the connection of embedded ties with longitudinal parts when the wood moisture changes, and therefore, the geometric stability and durability of the precast element.

On the edges of the horizontal sides of the longitudinal parts of the element is made symmetrically located relative to the transverse axis of the element grooves 11 and the protrusions 12. The grooves are designed to contain sealing elements horizontal joints.

Embedded links may be established with a constant and/or variable pitch and are located at the ends of the structure and/or offset from its ends.

At least one of the outer surfaces of the construction can be made with timber, logs, log siding.

To increase the strength of wooden prefabricated element may consist of two or more longitudinal parts (figure 3). Using wooden element consisting, for example, of the four longitudinal parts as wall cladding, not only increases its strength and thermal characteristics, but also by educated more cavities are provided accommodation in a time when the ranks of the genus utilities: electric, water pipes, etc. and also ensures that the installation of ventilated facades, which increases the service life and environmental characteristics of buildings.

To increase the strength of wooden prefabricated element longitudinal parts with embedded links in the joints are fixed wooden, metal or plastic parts or plates.

Prefabricated element 1 can be provided with ribs 13 arranged along the entire length of the element and secured to the edges of mortgages relations 3 (figure 5). Ribs can be made of sheet metal or composite materials. Precast element with ribs preferably be used as the supporting structure of the wooden structure: the joists for the floor, ceiling beams, rafter roofs, device load-bearing panels.

The above described modular elements set rows one above the other in height or next to each other with adjacent ends of the longitudinal parts of the adjacent prefabricated elements, form the cladding of the wooden structure as a vertical - external and internal walls, partitions and horizontal ceilings, floors, flat roof slopes.

The concept of "walling" in the claimed invention includes the entire surface of the vertical or horizontal ograj the surrounding structures, wooden structures, and part of it, for example, a section of wall between the window or door openings or when there is wall corner elements section of the wall between the latter.

Prefabricated elements 1 when used for exterior walls, depicted in Fig.7, are rows in height to each other and couple the end faces of the longitudinal parts 2 offset joint in each row relative to the joints of adjacent rows, i.e. with ligation of the joints.

In order to provide a minimum range of products 1, reduce the complexity of the construction process and to increase the applicability in design decisions when using them in the building envelope, the length of the product 1 must be a multiple of the modulus M, the size of which is equal to the distance between mortgage bonds established with the same pitch L along the length of the element, while at mortgage link element must be shifted by the length L/2 with the formation of open cavities, and the amount of displacement of the joints in each row is a multiple of the modulus M, which ensures the alignment of embedded links throughout the height of the vertical building envelope structure whether across the entire width or length the building envelope.

Exterior wall cladding in addition to the linear prefabricated elements can optionally contain angular elements, consisting of angled from 90 to 150° on the angle to the other two linear prefabricated elements, stacked in the corner of the end faces of the longitudinal parts 14 and 15.

The Assembly of the outer wall structure can also be implemented in a modular system. When using a corner element, consisting of two linear elements arranged at an angle from 90 to 150°, the internal length of the linear element must be a multiple of the modulus M (Fig.6), with extreme cage connection of precast element shifted by the length L/2, and the amount of displacement of the joints in each row is a multiple of the modulus M

Due to ligation of the joints in adjacent rows by the value that is a multiple of the modulus M of wall cladding (Fig), embedded link 3 over the entire height of the walls form a continuous vertical cavity 16, communicating with continuous horizontal cavities formed between adjacent prefabricated elements 1 adjacent rows.

Wooden prefabricated elements 1, collected in structure, form, thus a closed cellular cavity inside the walls, creating a unique ventilation. The air enclosed in the cavities of walls, has a static condition, provides effective thermal insulation. At the same time conditioning the interior of the air cavity is in the process of microcirculation through natural solid wood.

The through cavity in the building envelope can be filled with insulating Mat is the Rial, which uses eco-friendly materials based on ceramics, glass, cellulose, natural fibrous organics.

The thickness of the walls and partitions is from 125-400 mm, and a construction decision and up to 600 m Height precast element from 90 mm above.

In the case of wooden prefabricated elements 1 for vertical building envelope (exterior or exterior walls) when selecting wood for a vertical longitudinal parts 2 and during production in the factory is considered that one of the longitudinal parts are used as exterior wall of a building, and another (or others) as the inner wall, ready for use without any additional finishing.

Thus, in the claimed invention are eliminated expensive and time-consuming stages of finishing wood surfaces, such as alignment, trimming, sanding, putty, primer, paint, etc.

Prefabricated wooden elements 1 have a maximum degree of prefabrication with high quality species of surfaces and allow you to build the house for any purpose and complexity: from garden pavilions and summer houses to mansions premium in any architectural style.

The facades of the houses of wooden prefabricated elements 1 can be formed in different exterior styles: Brusova exterior, exterior siding, is Xterra original profile (figure 4), as well as in traditional log exterior.

Using wooden prefabricated elements 1 as a horizontal enclosure sections, for example, ceiling (figure 5), wooden prefabricated elements are placed in rows next to each other so that the longitudinal parts are arranged horizontally. Tykwa end faces of the longitudinal parts adjacent wooden elements in the row with ligation of the longitudinal parts of prefabricated elements, is formed to overlap with continuous horizontal cavities between adjacent wooden prefabricated elements.

For slabs of wood structures 1 also does not require additional finishing, as well as in the manufacture of one of the vertical longitudinal members considered that it will be used as the floor and the other as the ceiling. Formed cavity in the ceiling are used for installation of various types of communications, as well as in the cavity.

If bar construction has at least two veneer sheets, they are attached to each other with transverse stiffeners located in the gap between sheets. End of first-type bars which is directed into the gap between veneer sheets of second-type bars has no appropriate sections of longitudinal blocks, and ends of the rest block sections abut against ends of second-type bars blocks facing them.

EFFECT: improving bending strength of connection.

Ridge joint // 2340733

FIELD: construction industry.

SUBSTANCE: ridge joint consisting of wooden bars the ends of which are mated angle-wise in relation to each other and secured with connecting plates differs in the fact that bars section is made in the form of I-beam profile the web of which is made of at least two veneer sheets located with a gap and secured to each other with transverse stiffeners. Flanges are made in the form of bars fixed along longitudinal ends of sheets. At that web and flange ends of bars abut each other, besides connecting plates are located in the gap between veneer sheets as well and touch their external surface, and joint area is fixed with tightening elements. Besides longitudinal stiffeners attached to sheets surfaces are arranged in the space between veneer sheets. Connecting plates are made from veneer of the same thickness like thickness of webs, and have V-shaped outline. Joint is provided with additional connecting plate fixed on external side of flanges joint. Besides vertical and metal rod being more preferable is fixed in joint plane.

EFFECT: providing high strength and stiffness of bars connection, and minimising consumption of construction materials at increased bearing capacity.

FIELD: building, particularly to construct structures including wooden elements.

SUBSTANCE: method involves drilling holes in timbers, logs and other lumber; piercing timbers, logs and other lumber with transversal ties and tensioning thereof with nuts secured to ties; offsetting timbers, logs and other lumber in groups including two or more timbers, logs and other lumber relative previous ones during building erection so that extensions and depressions are formed in walls; applying glue between timbers, logs and other lumber; installing longitudinal ties in slots and connecting ends of each longitudinal tie not terminating at wall ends with one transversal tie; mounting walls on foundation; connecting all walls, intermediate walls and partitions; packing all joints along with mating extensions of one wall with depressions of another one; pressing all building components together with the use of ties and nuts; passing transversal ties through extensions of walls to be connected; tightening all joints by nuts through resilient members with force application thereto and securing floor, ceiling and roof panels to corbels having orifices for ties receiving. Above panels have vertical holes for ties insertion. Floor and corbel are supported by timbers or logs or other lumber. Walls are connected to foundation, floor, ceiling or roof through resilient members by transversal ties or nuts adapted to move in slots due to wood shrinking or becoming wet.

EFFECT: increased tightness of building joints, strength, reliability, service life, improved ecological safety, quality of building finishing, enhanced appearance, reduced time and cost of building erection.
