FIELD: construction engineering, particularly, devices and methods of manufacture of enclosing constructions for residential buildings. SUBSTANCE: enclosure frame has box and one or several leaves made of bars interconnected by means of tenons and ears. Each bar is cemented from several lamellas. Number of lamellas in each bar equals to sum of numbers of tenons and ears from bar one side and planes of cementing of lamellas coincide with conjugated tenons and ears. Method of manufacturing enclosure frame includes manufacture of bars by cementing several lamellas; formation of bars profile; cementing of box and leaves. Number of lamellas in each bar is taken equal to sum of numbers of tenons and ears from one side of bar. Formation of tenons and ears is effected during bar cementing by alternation of lamellas forming tenons with shorter lamellas forming ears. EFFECT: reduced labor input and material wastes. 17 cl, 14 dwg |
