Newly-increased stirrup 5 between by being welded to connect, it is described difference bean column nodes between newly-increased column longitudinal reinforcement 6 between pass through weld connect
It connects.
The structure glue refers to the high (compressive strength of intensity>65MPa, steel-steel just draw adhesive strength>30MPa, shearing strength>
18MPa), larger load, and ageing-resistant, endurance, corrosion-resistant, the performance stabilization in life expectancy, suitable for bearing can be born
The adhesive of the structural elements bonding of strength.
The beneficial effects of the utility model are:During carrying out increasing column section to reinforce bean column node, solve
The construction technology problem of the intensive interspersed reinforcing bar that can not drill of original structure beam steel, and reduce the destruction to original structure;Simultaneously
When increasing newly-increased column main reinforcement 7, without avoiding original Vierendeel girder 2, newly-increased column longitudinal direction steel can be welded directly on original Vierendeel girder 2
Muscle 6 improves the rigidity of frame column and the globality of bean column node.
