Joint structure of filled composite beam and reinforced concrete column using core diaphragm

摘要

The present invention suppresses deformation of the panel zone junction bracket and achieves a stable joint by improving the joint structure of the panel zone junction bracket and composite beam, which are pre-assembled on the reinforced concrete column. Provided is a joint structure of a filled composite beam and a reinforced concrete column using a hollow diaphragm. The joint structure of the filled composite beam and the reinforced concrete column using a hollow diaphragm according to an appropriate embodiment of the present invention is a panel that is pre-assembled to the reinforced concrete column and connected to the composite beam in the joint structure of the composite beam and the reinforced concrete column Zone bonding brackets are provided; The panel zone joint bracket has a +-shaped plate-like structure and has a lower connection plate having a plurality of lower bolt holes for steel bonding at each end, is horizontally arranged at a predetermined height from the lower connection plate, has a T-shaped cross section and is joined in a + shape An upper connecting plate having a plurality of upper bolt holes for steel joining at regular intervals, vertically positioned between the upper connecting plate and lower connecting plate, joined between the ends, and having vertical bolt holes for steel joining at regular intervals The connecting plate and the lower end are joined to the corners where the vertical connecting plate and the lower connecting plate meet, and the upper end is joined to the central portion of the lower surface of the upper connecting plate, and is characterized in that it consists of a plurality of connecting plate reinforcing yarns arranged in a circle.
