SET OF WINDOW SECTIONS (ALTERNATIVES) AND FRAME SECTION FOR THIS SET (ALTERNATIVES) Russian patent published in 2002 - IPC

FIELD: construction engineering; building structures and materials for construction and reconstruction of public and private buildings; hollow window sections made in particular of polyvinylchloride and aluminum. SUBSTANCE: set has cellular sections of window frame, leaf, and transom bar; frame and leaf have projecting member which is extension of front surface B of respective section; transom bar has two projecting members. Slot for installing sealing gasket is made on rear surface A of projecting member of each mentioned section. Locating projection is made on inner surface E1 of frame, window leaf, and on side surface E2; locating slot receiving fastening member is made in mentioned locating projection. Thickness h of frame section, window leaf, and transom bar between front surface B of section and rear surface C is 61 to 63 mm. Distance s from mentioned rear surface C of section to rear surface A of respective projecting member is 47 to 50 mm. Depth of slot for installing sealing gasket, as measured from mentioned rear surface A of projecting member, is 4,1 to 5.5 mm; width d on entering end of slot is 2.9 to 4.1 mm; length e of mentioned entering end of slot is 1.1 mm to 1.9 mm. Height f of locating projections is 3.9 to 4.3 mm relative to inner surface E1 of frame and to window leaf or respective side surface E2 of transom bar; distance g from rear wall F of locating slot is 3.1 to 3.9 mm; width k of entering end of slot is 3.6 to 4.2 mm. Frame section for set of window sections includes cellular body with projecting member which is extension of front surface B of body. Facilities for joining additional sections are installed on outer surface D of body. Facilities for joining additional sections are made in the form of five fixing projections arranged in tandem starting from front surface B of body. Distance a1 between relatively closest points of first and fifth fixing projections is 53.4-54.6 mm. Distance a2 between relatively closest points of second and fourth fixing projections is 36.4-37.6 mm. Distance a3 between relatively closest points of third and fourth fixing projections is 27.9-29.1 mm. Thickness b of external part of fifth fixing projection which is extension of rear surface C of respective section, as measured starting from said surface is 3.2-4.4 mm; second, third and fourth fixing projections are installed at angle of approximately 80 deg to mentioned outer surface D. Facilities for joining additional sections are essentially assemblies of two fixing projections. Distance a1 between relatively closest points of mentioned projections is 53.4-54.6 mm. Mentioned facilities include also adapter designed for installation between mentioned fixing projections of frame; three fixing projections of adapter are arranged in tandem on adapter. Distance a2 between relatively closest points of first and third fixing projections of adapter is 36.4-37.6 mm. Distance a3 between relatively closest points of second and third fixing projections of adapter is 27.9-29.1 mm. Thickness b of outer part of fixing projection of frame body which is essentially extension of rear surface C of respective section, as measured starting from this surface, is 3.2-4.4 mm; fixing projections of adapter are installed at angle 80 deg to outer surface D1 of projection-mounting adapter. EFFECT: reduced material consumption; enhanced reliability of set due to more accurate choice of overall and locating dimensions of sections and dimensions of section fixation members. 16 cl, 8 dwg
