Respectively by being welded and fixed between the metal bellows and concrete-filled steel square tubular column, steel end plate and H profile steel beam.
The high-performance filler is ungauged regions self-compacting high-strength concrete.
Compared to prior art, the utility model has the advantages that：
1st, assembled concrete-filled steel square tubular column described in the utility model and steel beam connecting joint first will in work progress
Beam column component is prefabricated in the factory batch production out, and metal bellows is embedded in into square steel tube when factory makes quadrate steel pipe column
In post, concrete grouting is carried out to quadrate steel pipe column in factory, form concrete-filled steel square tubular column；Steel end plate is welded on H profile steel beam-ends
Portion；Then by girder steel component and it is embedded with the concrete-filled steel square tubular column of metal bellows and is transported to job site, at the scene to gold
Category bellows carries out pouring into for high-performance filler, is inserted into connector and fixes, and treats that the high-performance filler in metal bellows reaches
To after requirement of strength design, then each girder steel component and concrete-filled steel square tubular column are carried out into bolt connection by connector, really done
Arrive prefabrication, the architectural process of on-site consolidation, so as to effectively improve the speed of construction, and safety and reliability is obtained
To significantly being lifted.
2nd, when girder steel component suffers damage, due to convenient dismounting, so as to effectively improve the feasibility of later period maintenance, and
And allow the recuperability of the structure using this scheme to be greatly improved.
3rd, built-in metal bellows is conducive to being attached the positioning of part, high-performance can be poured in metal bellows and is filled out
Material, compared to the type of attachment for not adopting metal bellows, connector can be effectively improved in square steel using metal bellows
Adhesion strength in pipe concrete column.
The utility model is described in further detail below in conjunction with drawings and Examples；But a kind of dress of the present utility model
