CONSTRUCTION THERMAL SQUARED BEAM Russian patent published in 2014 - IPC E04C3/12 E04C1/40 

FIELD: construction.

SUBSTANCE: thermal squared beam comprises wooden parts-lamels, connected to each other by means of pins, with deepening of the latter by 1/3 of part thickness, and a sealant between parts-lamels. The sealant is a thermal insert either from foam polyethylene or from polyethylene with a single-sided or double-sided reflecting coating using foil and/or metallised lavsan, either from a different heat-sound insulating material. Dimensions of the thermal insert by length and width are equal to dimensions of wooden parts-lamels, and its thickness is taken within the 3 mm and above. Plastic spacer rings are installed onto pins, with thickness less than thickness of the thermal insert by 0.5-1 mm, in which holes are made for these rings in advance. With reduction of pin quantity on the squared beam the outer diameter of spacer rings is increased.

EFFECT: higher heat and sound protection properties of a squared beam.
