摘要
FIELD: construction.;SUBSTANCE: method to arrange joint units includes installation of lower columns, crossbars, ceiling slabs, upper columns and monolithing of column joints with crossbars and upper areas of crossbars. Lower and upper columns are columns of floor sectioning with holes in upper ends and reinforcement rods in lower ends. A conductor is fixed at the end of each column prior to assembly. The conductor forms between its body plane and the upper end of the column a space for a monolithic node joint and a hole for reinforcement rods in a finished joint. Precast crossbars are installed at the ends of columns, providing for contact of double-sided slopes of their support ends with setting columns of conductors. Monolithing of column joints with crossbars and upper areas of crossbars is carried out prior to removal of conductors from ends of lower columns. Conductors are removed from columns after formation of an initial structure of concrete in a ceiling. Upper columns are installed after concrete gains design strength, connecting them with the lower ones by means of a plug joint.;EFFECT: reduced metal intensity, higher accuracy of performance, liquidation of welding and forming works on a construction site.;5 dwg
