The invention relates to the field of construction, namely the construction of wood walls, and can be used in the construction of new and reconstruction of existing small buildings and low-rise buildings.

Famous wooden construction element made in the form of glued-edged boards with longitudinally located a V-shaped projection on the upper edge and a corresponding groove on the bottom edge (patent RU 28878, publ. 20.04.2003). On the front side of the Board near the top ledge and the bottom of the longitudinal groove are chamfered, and on its rear flat side at the top and bottom longitudinally are deaf slots of rectangular cross-section designed to accommodate horizontal upper and lower spacer elements made of solid plywood sheets. The above construction allows to make the box-shaped beam using a pair of cut boards, where the inner hollow space of the beam, limited established in its length upper and lower spacer elements filled with insulating material in the form of mineral wool, with the ends of the box beam closed with plywood sheets. Using the above box-shaped beams, which are arranged longitudinally of one another, erected a wall of low-rise wooden is home, with the placement of the wedge-shaped protrusions of one of the box beams in a wedge-shaped grooves of the other beam. Between the bottom spacer element upstream of the beam and the top spacer element downstream of the beam formed by the gap, which is filled with insulating sealing material. The disadvantages of the known wooden construction element are its low strength characteristics of a weakened wall, located in the lower part of the laminated element between the longitudinal wedge groove and the longitudinal slot of rectangular cross-section, designed for installation of the bottom spacer element, additional labor costs required for bonding, and the danger of cracking and warping due to temperature difference and humidity. The disadvantages of the known box-beam follow from the disadvantages of the above-mentioned construction elements, from which it is made, to the same box-shaped beam has a small spatial rigidity and relatively high complexity in the manufacture, requiring during its Assembly special tools for fixing in vertical position is unstable wooden construction elements. The disadvantages of the known walls of low-rise houses follow from the disadvantages of the above-mentioned box-beams, of which it is composed to the same wall has an imperfect design, requires giving it extra stability during erection, apply a large number of adhesives, fasteners and sealing material placed between the spacer elements and box beams, and the technology of construction of the wall has a high complexity and multi-stage, contributing to the accumulation of dimensional errors in its manufacture, which affects the quality of work, while there is a danger of destruction of the joints glued laminated structural elements under the influence of external climatic factors.

Also known panelized home construction in which the wall panel consists of a set of squared construction of elements of a given length, stacked on each other along the height of the panel (patent CA 2541653, publ. 09.10.2006). At the ends of each slab element made spikes that when laying the boards to each other come into the slots of the uprights, framing the panel on both sides. On thorns of the bars and grooves of the uprights fixed with the help of short metal screws cushioning insert U-shaped form. On the upper side of each beam is made of a longitudinal crest rectangular cross section, and the lower side is made a longitudinal groove corresponding section, and when mounting bars comb enters the groove and form a solid wall design is uccio. In joints installed at each other planks laid sealing materials, and the bars fastened together along the length of the junction of the long screws. The front side of the beam top and bottom has a rounded shape, and its rear side is made flat. In bars drilled matching the height of the wall panels internal vertical channels through which the panel ignored the tension rods, the lower ends of which are attached to the Foundation, and on the upper threaded ends screwed wrench hinges with holes for insertion of the levers needed for screwing the hinges and tension rods. In the wall panel is also provided with channels for laying communications, in which, as needed, in place of the wires and pipes. Framing panel pillars attached to a supporting beam, laid on the Foundation. The disadvantages of the known wooden slab of a building element is the low level of technology of its manufacture, require a large amount of manual labor and primitive equipment, which affects the time and the build quality of the panel, the necessity of using a leveling metal liner inserts U-shaped spiked timber because of their large variations in size and shape. The disadvantages of the known panel design the walls of the house are high in oven of labor required for the installation of large-squared building elements, of which is assembled wall panel, imperfect and cumbersome panel design due to the presence of thermal bridges in the vertical joints of the racks and the large number of fasteners and sealing material between the upper ridges and lower grooves of the bars, the need for additional insulation wall structure, as well as problems while installing roofing elements of the protruding upper wrench loops over the wall panel, the danger of warping solid bars in length and cracking due to differential temperature and humidity between the inner and outer environment.

As a prototype adopted demountable wall panel, made of wooden construction elements having a multilayer structure of brick, composed of two symmetrical wooden packages, separated from each other by spacer elements (patent KR 20060025321, publ. 21.03.2006). One embodiment of the wall panel provides the use of a construction element, in which parallel spaced packages are installed on edge and fastened together by the flat sides of two pieces of boards. The top, bottom and end edges of boards in both packages is shifted such that the top and at one end of the building element form stico the full-time fixture in the form of a double longitudinal crest, and in the lower part and at the other end to form a connecting device in the form of a General longitudinal groove (see Fig. 1A, 1b and 1C). Using the docking fixtures construction element in the panel connected with other building elements. Spacer elements separating the packages from each other, is made of short pieces of boards and fixed to the inner surface of the package, forming between them a narrow inner hollow space. In the spacer elements are made through holes for installation in the internal hollow space of the horizontal tensioning devices. On the outside of the packages made open channels for installation of exterior vertical tensioning devices. Tensioner is made in the form of metal rods with threaded ends, which, when installed in the channels, are screwed crimp nuts. Using the above construction element made in the form of laminated wooden bricks, going wall panel, under construction where building elements are stacked on the lower tier sequentially one after the other, while on the upper tiers one above the other, with the placement of the ridges of one element in the groove of the other. The extreme upper and lower tiers of the construction elements arranged in panels, as well as their lateral lines are connected to tagName devices which pass through the panel and tighten using crimp nuts, pulling together the tiers and rows of masonry in the construction of the wall panel. The disadvantages of the known wooden construction element made in the form of laminated wooden bricks are of poor quality and low level of technology, characterized by a high percentage of wood waste in its production carried out on primitive equipment with high costs of manual labour, difficulties in maintaining the required installation dimensions and shape of the element, causing the need to fit each building element when installed in a wall panel that has a negative impact on time and quality of the bezel Assembly, the risk of warping and delamination due to the heterogeneous structure of the material and the temperature and humidity, the need to use adhesive and fastening materials in connection scraps of boards in the packages. The disadvantages of the known collapsible wall panel follow from the disadvantages of the above-mentioned construction elements, of which she is going to the same technology of construction of the wall has a high level of complexity, as the wall panel has a bulky design that lacks the solidity and rigidity, so the build time she needs is odimo providing additional stability and/or stacking structure in a horizontal position, that creates difficulties for working, also there is a danger of warping and crevices in the building elements and the deformation of the wall panel during operation due to differential temperature and humidity between the outer and inner environment, which will cause the necessity of using a large number of sealing materials for sealing cracks and outer channels under tension device, and perform insulation and finishing works.

The technical task, for which we offer this invention is to improve the quality wooden construction element and the reliability of its butt joints in masonry walls, ensuring the durability and solidity of wall structure, reducing the complexity of manufacture of the construction element and the wall with full factory readiness for wasteless technology that allows you to quickly assembled at the construction site of decorative wall designs that do not require additional, including finishing and having means for regulating deformation, the unification of the size and shape of the construction elements and the creation of a unified database of standard parts, which you can use automatic methods design of individual projects small is traini and low-rise buildings with comfortable layout.

The mentioned technical problem is solved, we offer wooden construction element, on the top, bottom and end faces which made connecting devices, with a docking device, made on the top and one side, consist of at least one longitudinal ridge, and the docking devices are made on the bottom and the other end side, consist of at least one longitudinal groove. What's new is that the face side of the construction element made in the form of wavy bent matching between surfaces with inclined upper and lower sections, where curved surfaces are back symmetrically relative to the longitudinal axis of the element and their ramps is limited by its height H, with one curved surface mating with the upper side of the element made of longitudinal ridges, and on the other curved surface mating with the lower edge of the element made of longitudinal grooves. The quality of the building element is better, if it will be manufactured in factory conditions of homogeneous wood natural drying. Depending on the size of the erected wall, the dimensions of the building element can be: length L from 300 mm to 600 mm, height H from 80 mm to 150 mm, In width from 40 mm to 60 mm, Optimally, e is whether wavy curved end surface of the element will contain at least one peak and one trough, that will allow them a full match. Peaks and troughs wavy curved surfaces can be displaced relative to the longitudinal axis of the element at a distance e, which may be no more than 1/22 its height H, to avoid shear wave surfaces of the building element during manufacturing. Preferably, if the angle α of inclination of the inclined sections wavy curved surfaces will be from 30° to 90°. On the upper side and on mating with her curved surface of the face side can be performed two longitudinal ridge with sloping walls and on the bottom side and mating with her curved surface of the face side can be performed two longitudinal grooves with inclined sides, which will ensure their reliable lock connection. It is advantageous if the angle β of inclination of the walls of the grooves will be from 30° to 60°. One of the lateral sides of the construction element can be made a slot to insert the end of the spacer element. Wall of a building erected on a concrete Foundation using the proposed wooden construction element on the top, bottom and end faces which made connecting devices in the form of longitudinal grooves in the masonry construction elements arranged in two p is on an edge, where longitudinal ridges located on the top and one end side of the building elements, connected with longitudinal slots located on the bottom and other side items, all joints of masonry compressed tensioning devices, and the rows of masonry separated from each other by spacer elements and between them is located the inner hollow space. What's new is that as wooden construction elements for masonry walls used in the construction element according to any one of items 1 to 10, the front side of the building elements are connected via the clutch by applying the matching between a wavy curved surfaces on each other, the ridges and grooves which are connected in castles, in which there are no gaps and voids, thus locking connection of one tier of the masonry offset tool joints other tiers of masonry, under the lower tier of the masonry laid the supporting bars, and on top of the upper tier of the masonry laid clamping bars installed on the base plate tensioning device located in a vertical the position in the internal hollow space between the rows of masonry, which makes the wall strong and solid. Ligation of building elements more reliable, if locking connection in tiers of masonry will be offset from each other by half the length of e is amenta. Vertical tensioning device can be made in the form of wire rods, the lower end attached to the anchor Foundation and an upper end connected to the base plate that will allow the seal butt joints of masonry. To regulate the deformation of the wall optimally, if the ends of the spacer elements will be installed in slots on the inner sides of building elements with a vertical back-and-forth movement. Depending on operating conditions, masonry walls can be made with the possibility of use as an external wall and/or inner walls and/or partitions in the internal space which can be done laying communications, and as heat insulating and sound insulating material can be used sawdust and/or small chips, which are waste after processing of building elements. Wall meets its purpose, if it will hold the door and/or window openings, as well as corner joints with the walls and partitions. In the openings and corner joints, located on the street side, end connections can be made in the form of the "swallow's tail", and in the corner joints located on the room side, end connections can be performed back to back with double the ridges and grooves on the abutting surfaces, that will allow wall rigidity and strength. It is advantageous if the overlapping openings lintels are made of lumber of the appropriate size with end docking devices, consistent with end docking fixtures building elements that will keep the pattern of the brickwork. On the visible sides of the building elements can be made decorative screw ornament that enhance aesthetic appreciation from the pattern of masonry walls.

FIELD: construction.

SUBSTANCE: invention refers to the sphere of construction technologies and immediately deals with glued wooden structures. The suggested method of pre-tension of glued wooden packages in the across-grain direction presupposes their compression with the help of steel rods. The element of novelty consists in applying to the wooden package being forced together a pressure of 0.5 MPa with the help of steel rods gummed down inside the pre-drilled holes arranged along the whole of the package length (the spacing being equal to 300-500 mm.). The length of the rods is equal to the package width with due allowance for its eventual reduction after application of force-together pressure.

EFFECT: minimisation of material and labour expenditures related to pre-tension of glued wooden packages in the across-grain direction without distortion of their overall dimensions.
