BUTT CONNECTION OF MODULAR COLUMNS TO COVERAGE AND METHOD THEREOF Russian patent published in 2008 - IPC E04B1/38 E04B1/20 

FIELD: constructional engineering.

SUBSTANCE: invention refers to constructional engineering, in particular to butt connection of modular columns to coverage and to method thereof. Butt connection includes bottom segments of lower and upper columns vertically fixed on reinforced concrete framing axis with height fracture, and coverage placed between end faces of columns. Screw-threaded longitudinal reinforcement escapes pass through coverage. Escapes ends are fitted with screw nuts to lateral steel sheet in recesses provided in upper column. The sheet is rigidly connected to end face of the upper column. Then recesses are calked with rapid-hardening fine concrete. Over coverage top there are aligner nuts provided for upper column support. Coverage has centre tube to grout rapid-hardening fine concrete. Also, coverage is supplied with openings with anchored metal pipes. Lower column longitudinal reinforcement escapes pass through each metal pipe. Metal bolsters are fixed in opening metal pipes under coverage and under each aligner nut over coverage in rapid-hardening fine concrete layer on longitudinal reinforcement escapes. Bolsters are made as truncated cones with theirsmaller bases directed towards each other. Metal gaskets are fixed between end face of lower column and bolsters.

EFFECT: increased reliability, construction accuracy, more rapid construction and reduced steel intensity.
