DIAPHRAGM OF JOINTLESS OSSATURE BUILDING Russian patent published in 2009 - IPC E04B1/20 E04B5/43 

FIELD: construction.

SUBSTANCE: invention is related to the field of construction, in particular to diaphragms of jointless ossature buildings. Diaphragm is installed between columns, foundation, intercolumn and above-column slabs and is connected to them by means of embedded components and reinforcing bars. Diaphragm is made of central and two side parts connected between each other in the same vertical plane. Width of diaphragm central part is equal to length of intercolumn slab. Central part of diaphragm from three sides - upper one and two side ones, and every side part of diaphragm from two sides - upper and side ones from the side of central diaphragm are equipped with loop projections. Lateral sides of central part is connected to side parts by means of reinforcing rods. Reinforcing rods are installed between slabs vertically in openings that are formed by loop projections during joining of parts towards each other. Ends of reinforcing bars are installed in splined seams of intercolumn and above-column slab joints. Every side part of diaphragm from the side of column is equipped with embedded "П"-shaped components. Columns, between which diaphragm is installed, are equipped with plate embedded elements. Embedded elements of columns are installed opposite to "П"-shaped embedded elements of diaphragm side parts and are rigidly fixed to them. In every intercolumn slab installed above central part of diaphragm, square opening is provided, being edged with angle. Opening contains fastening element arranged in the form of two grids of L-shape. Grids are connected to angle and loop projections of diaphragm central part. Central part of diaphragm is connected to side parts of diaphragm with the help of reinforcing bars that are passed horizontally through openings of all upper reinforcing projections of all diaphragm parts. Splined seams between parts of diaphragm and adjacent splined connections of slabs, and also joints of intercolumn slab and diaphragm are filled with concrete.

EFFECT: higher reliability of structural joints and seismic stability, lower labour intensiveness of structure erection.
