Advocate building industrialization and green building.And cast-in-place concrete structure environmental pollution is big, material and energy resource consumption are high, construction material
Recoverable rate is low, has not met the Architecture Policies of country-driven " being suitable for, economy, green, attractive in appearance ".Due to assembled
Combinative structure has energy-conserving and environment-protective, and speed of application is fast, and industrialization degree is high, can solve China's building industrialization level low, room
The problems such as room construction effort productivity ratio is low and conventional house product quality is low, adapt to the development of China's building trade.
Assembled concrete-filled steel square tubular column-steel-beam combination structure as the important branch in assembled combined structure system,
Also there is every feature of assembled combinative structure.Nowadays it is also applicable among Practical Project, and existing square steel tube coagulation
Earth pillar is complex with steel beam connecting joint working procedure, and construction technology difficulty is relatively big, considerably increases difficulty of construction, is unfavorable for
Improve speed of application, directly affect speed and the assemblingization degree of structure construction simultaneously.
Summary of the invention
The present invention proposes concrete-filled steel square tubular column and steel beam connecting joint in a kind of assembled combinative structure, and its purpose exists
In overcoming the defect of prior art, meet the every mechanical property of node, and realize the assembling of structure, improve the assembled speed of component
Degree, fully adapts to requirement and the feature of assembled combined structure system.
For achieving the above object, the technical scheme that the present invention proposes is that a kind of assembled concrete-filled steel square tubular column connects with girder steel
Connect node, including concrete-filled steel square tubular column prefabricated component, girder steel element and some connectors；Concrete-filled steel square tubular column prefabricated component bag
Include the concrete-filled steel square tubular column formed by square steel tube casting concrete and some metal bellowss, the metal bellows side of being embedded in advance
It is used for pore-forming in quadrate steel pipe column in steel core concrete column, and hole one end open is positioned at concrete-filled steel square tubular column and connects on side；Steel
Beam includes H profile steel beam and steel end plate；It is filled with high-performance filler in metal bellows, connector is inserted one to one
Metal bellows is fixed, after high-performance filling intensity reaches design requirement, connector with the fastening of steel end plate thus is realized
Concrete-filled steel square tubular column and the connection of H profile steel beam.
Being provided with some bolts hole on described steel end plate, bolt hole is correspondingly arranged with connector position；Described connector one
One correspondence through bolt hole and and appended claims, the mode being bolted realizes concrete-filled steel square tubular column and H profile steel
The installation of beam connects.
Described connector is screw rod or threaded reinforcing bar；The 3～7 of described metal bellows a diameter of connector diameter
Times.
Described securing member includes nut and pad.
Respectively by being welded and fixed between described metal bellows and concrete-filled steel square tubular column, steel end plate and H profile steel beam.
Described high-performance filler is ungauged regions self-compacting high-strength concrete.
Compared to prior art, the method have the advantages that
1, assembled concrete-filled steel square tubular column of the present invention and steel beam connecting joint are in work progress, first by beam column
Component is prefabricated in the factory and produces in batches out, and when factory makes quadrate steel pipe column, metal bellows is embedded in quadrate steel pipe column
In, in factory, quadrate steel pipe column is carried out concrete grouting, form concrete-filled steel square tubular column；Steel end plate is welded on H profile steel beam end；
Then by girder steel assembly and be embedded with the concrete-filled steel square tubular column of metal bellows and be transported to job site, at the scene to metal wave
Stricture of vagina pipe carries out pouring into of high-performance filler, is inserted into connector and fixes, and treats that the high-performance filler in metal bellows reaches strong
After degree design requires, more each girder steel assembly is carried out bolt with concrete-filled steel square tubular column by connector it is connected, be truly realized
Prefabrication, the architectural process of on-site consolidation, thus effectively improve the speed of construction, and safety and reliability obtains greatly
The lifting of width.
2, when girder steel assembly suffers damage, due to convenient dismounting, thus the feasibility of later period maintenance is effectively improved, and
And allow the recuperability of the structure applying this scheme be greatly improved.
3, built-in metal corrugated tube is conducive to being attached the location of part, can pour into high-performance and fill out in metal bellows
Material, compared to not using the type of attachment of metal bellows, uses metal bellows can effectively improve connector at square steel
Adhesion strength in pipe concrete column.
Below in conjunction with drawings and Examples, the present invention is described in further detail；But a kind of assembled square steel of the present invention
Pipe concrete column and steel beam connecting joint are not limited to embodiment.
