CONNECTION POINT OF COLUMN AND FLOOR SLAB OF BUILDING WITHOUT HEAD OF COLUMN AND CROSS-BAR Russian patent published in 2015 - IPC E04B1/38 

FIELD: construction.

SUBSTANCE: invention relates to the construction, in particular to the connection point of column and floor slab for prefabricated frame of the building without head of column and cross-bar. The connection point includes the interconnected top and bottom columns and prefabricated floor slab with the hole for passage of prefabricated columns around the perimeter of which the metal shell is rigidly fixed to effective reinforcement, made in the form of two hollow truncated isosceles tetrahedral pyramids, coupled along the perimeter of minor bases. Free lengths of effective reinforcement of the top and bottom columns to be jointed are welded inter se and with the upper portion of the shell by means of metal connecting elements. The lower edge of the shell is spaced from the lower edge of the slab to the value of protective layer of concrete equal to 15-20 mm, and wire rod with diameter of 8-12 mm is mounted along the perimeter of the lower edge of the shell, besides the connecting element is designed in the form of isosceles triangle.

EFFECT: increase of the connection point rigidity.
