FIELD: construction.
SUBSTANCE: invention relates to the field of construction, namely to the interconnection unit of pipe-concrete columns with tie beams of frame buildings. Unit includes coaxially interfaced steel pipes with concrete filling inside, which are connected to each other and to tie beams by interconnection element. Supporting tables (6) are attached to steel pipes at points of connection of columns with beams. Steel pipes have vertical slots. Junction connection element consists of a core made of a steel pipe, at ends of which there are flanges with holes, and vertical plate. Inside the concrete filling of the columns there is a prestressed rod connected to the core by means of a tensioning device.
EFFECT: technical result consists in improvement of carrying capacity of unit.
