METHOD FOR MANUFACTURING OF MULTICHAMBER LAMINATE CONSTRUCTION ELEMENT Russian patent published in 2010 - IPC C09J5/00 

FIELD: construction.

SUBSTANCE: invention relates to method for manufacturing of laminate wooden parts and elements, namely multichamber ones, in construction, furniture making. Method for manufacturing of multichamber laminate construction element, which consists in manufacturing of multichamber element from previously prepared board materials and lamellae and insulating material cut accordingly, with the help of layout table with heating, which in its turn consists of lower table, movable upper slab with drop-out guides and with hydraulic cylinders with pushers. Lamel with slots and dowels inserted as glued into "dead" holes in element stock is laid onto lower table in front of press, transverse power spacers are glued to protruding ends of dowels. Longitudinal parts of power frame are placed into slots of lamel and power spacers with applied glue. Insulating material is laid into produced pockets. Afterwards heating of lower table is switched on, with the help of coolant - air, water, passing along strengthening tight box installed under lower table. Assembled stock is placed into press so that upper part of power spacers is installed into guides on lower surface of movable upper table. Afterwards stock of multichamber element is aligned by marks on press and is exposed to pressure with the help of hydraulic cylinders of press with pushers. After lifting of upper plate, the stock is again moved to free part of lower table, and the second lamel is laid on top of it, with applied glue. Its longitudinal parts are inserted into according slots, and protruding ends of dowels - into openings of power longitudinal spacers. Assembled element is turned by 180 degrees to prevent outflow of glue. After inspection of assembly accuracy, the element is placed into press, with previously dropped out guides on upper plate. Upper plate lowers to the fixed level, creating pressure at element components and developing a required geometric size. Heating is switched one, and after required time delay assembled element is moved to section of finishing works.

EFFECT: invention makes it possible to produce multichamber laminate construction element in fast and manufacturable manner.
