With earthquake energy, while rubber slab 3 can also be protected beam-ends concrete by pressure side.After geological process disappears, presstressed reinforcing steel 8
Prestressing force, the angle steel 4 that consumes energy elastic restoring force pull back bean column node, so that bean column node is restored normal position, reinforced beam 2
Opening at girder end closure, friction plate 3 spring back.Bean column node and its each element return to normal position, and whole process bean column node is not
It generates and destroys or only generate slight damage, can be used continuously by simply repairing.
Traditional bean column node makes the two form an entirety by Cast-in-situ Beam, column component simultaneously, and joints are complicated, leads to
Component itself energy consumption is crossed, is destroyed serious.The utility model individually pours two components, is initially formed two component independences, in this way
Stress between them becomes simply, is only pressurized, and without pulling force and Moment, extent of the destruction is reduced.But two independent
Component cannot cooperate, it is necessary to connect the two independent structures by facilities such as deformed bar, energy consumption angle steel again
Part, thus bean column node forming entirety, can cooperating, thus beam, column component connects and is formed
Frame structure.And the elements such as deformed bar, energy consumption angle steel, friction plate will also play the role of consuming most of seismic energy,
Just further reduce the destruction of beam, column component itself.
