METAL TRUSS-TO-COLUMN CONNECTING UNIT Russian patent published in 2000 - IPC

FIELD: civil engineering; industrial buildings. SUBSTANCE: unit connection of bottom chord with column has H-section column, support strut connected with truss bottom chord. Two symmetrical teeth - locks with standard ends are secured on support strut and bottom chord. Support table made of two symmetrical angle plates is secured on column. Holes are made in column flange over contour of angle plates into which angle plates are fitted. In process of manufacture, holes in horizontal web of angle plates are registered relative to column face by template. Length of attachment of table depends on support reaction of truss, and at heavy forces, table can be extended to opposite flange of column. Forces from table are conveyed to column flange through zones of contact of table. Table can be welded by minimum-height weld to column flange through zones of contact of table. Table can be welded by minimum-height weld to column flange to prevent rusting, or non-welded. Outward thrust from truss to column is conveyed through milled ends faces of support strut and column bottom chord. Angle plates straddle wall from two sides, thus providing stability. EFFECT: provision of possibility of truss mounting without verifying, enhanced quality of connecting unit. 2 dwg
