BUTT JOINT OF REINFORCED CONCRETE FLOOR WITH A COLUMN Russian patent published in 2022 - IPC E04B5/43 

FIELD: construction industry.

SUBSTANCE: invention relates to the field of construction, namely to the butt joint of a reinforced concrete floor with a column. The butt joint of a reinforced concrete floor with a column includes a floor slab, columns of the upper and lower tiers containing reinforcing frames, rectilinear metal inserts made in the form of plates installed through the column and connected to the frame of the column and the floor slab. The sections of metal inserts located between the longitudinal reinforcement of the column frame of the lower tier have an increased height, and the space between the metal inserts from the level of the bottom of the floor slab to this height is filled with vibration dampers made of two layers of identical elements shaped like regular pyramids with square bases. The bases of each pyramid layer are in contact with the side faces of the neighboring elements of the other layer, and the vertices of the pyramids of each layer touch the horizontal surface formed by the bases of the other layer. The empty space between the metal inserts and the side surfaces of the regular pyramids is filled with elastic material.

EFFECT: reduction in the intensity of vibrations of floors and columns.
