METHOD OF FABRICATION OF PACKET WOOD UNIT Russian patent published in 2014 - IPC E04C2/10 

FIELD: construction.

SUBSTANCE: method of fabrication of a packet wood unit consists in that the boards are cut into equal lengths, stacked on each other, but before that they are lubricated by an adhesive substance in places of their contact with each other, then they are compressed with a press. The boards are preliminary divided into two parts by an oblique cut, parallel to their longitudinal axis, then the boards are stacked between the planes of the assembled press clip at each other in the first row with the long sides so that the oblique cuts are directed to one side. The indicated row of boards is joined with the second matching row of boards, which is a mirror image of the first row. After connecting the boards into a packet, it has the form of a "herringbone" in the cross-section with top from one side and in the form of a "dovetail" from the other side. When assembling, the boards of the first and second rows are lubricated in their places of contact between each other by the specified adhesive substance. Laying is performed in alternation order of boards of the first and second rows up to the contact of ends of subsequent boards of one row with the lateral side of the previous boards of the other row. This is followed by formation of the packet via the mentioned compression of boards by the press, besides the line of the press force application lies in the longitudinal plane of the packet from the "herringbone" top to the "dovetail" and is perpendicular to the transverse plane of the packet. Transoms with a triangular cross-section with the possibility of plane formation along the packet side are attached integrally from the side of the "herringbone" top. A wood unit is formed by subsequent compression, preferably in the form of a rectangular parallelepiped in plane, after which the connecting means are produced therein for adjacent wood units in the form of alternating protrusions and depressions on the lateral sides, mounted in the middle of the wall of wood units, and the lateral side of angular wood units is designed in the stepped shape in a cross section, corresponding to the stepped form of the conjugated angular wood unit, then apertures for placement of windows, doors and other home accessories are made in the wood units of the outer and inner walls.

EFFECT: reduction of labour intensity and energy costs for manufacturing of the wood unit due to the use of equipment for pressing small capacities.
