METHOD AND APPARATUS FOR MANUFACTURE OF WOODEN-METAL BEAMS Russian patent published in 2005 - IPC

FIELD: construction industry, in particular, production of bearing beams and columns in erecting of buildings and constructions for various purposes.

SUBSTANCE: method involves manufacturing T-shaped metal core by cold forming process; covering wooden faceplates with isolating materials and joining through washers by means of rolled-out surfaces of ends of hollow rivets inserted into receiving holes of core and faceplates, respectively; providing congruent shape of faceplates by milling; assembling and connecting core composed of plates and formed corner members in basic rectangular guiding devices for longitudinal welding and joining, said guiding devices having rotary tables equipped with device for clamping T-shaped core corner member; assembling faceplates joined with core on working table embedded centrally of base by means of at least two parallelogram contours, said working table being made in the form of rectangular bar adapted for displacement in vertical plane and equipped with clamping device located on its sides and designed for clamping of parallelogram-shaped faceplates by providing assembling operations at both sides of beam with the help of processing unit. Apparatus has processing unit, which comprises carriage interconnected with base for coordinate displacement by means of two-contoured chain drive. Power heads and charging devices defining operational units are symmetrically positioned on carriage.

EFFECT: increased efficiency and wider range of usage.
