WOOD-METAL BUILDING MEMBER Russian patent published in 2003 - IPC

FIELD: construction engineering, particularly, wood-metal structures; applicable in capacity of posts in frame-panel structures. SUBSTANCE: wood-metal building member consists of metal core in form of pipe rectangular is section and wood cover plates interconnected by metal pins. Boundaries of joint between metal and wood are filled with material filling voids and roughnesses and protecting metal from corrosion, and imparting high fireproofing and adhesive ability. Fabrication of wood-metal building member with ratio between thickness of metal core wall and thickness of wood cover plates of (1-4)-8 provides for additional increase of resistance to eccentric compression with use of building members in capacity of post. EFFECT: increased strength and rigidity of posts under conditions of eccentric compression with reduced weight of building member. 5 cl, 3 dwg
