Description
Technical field
The present invention relates to a kind of complete prefabricated detachable assembling type beam-column connections, belong to technical field of structural engineering.
Background technology
Building trade in traditional production model relatively dispersion and production level and production efficiency it is relatively low under.
Still using this structural system of armored concrete as one of main mode of production of building trade in China, engineering.Wherein
With the wet cast-in-place structural system done based on industry, there are many problems, as waste of material is more, manual operation is more, working at height is more, wet
Do that industry is more, field fabrication is more etc., since these problems make engineering long construction period occur, engineering cost is difficult to control, engineering
Quality is relatively difficult to guarantee, therefore this structural system is difficult to meet the needs of building Mirae Corp.ization development.
It is excellent that prefabricated concrete structure has that construction duration is short, product quality is high, energy loss is low, environmental pollution is small etc.
Gesture is the inevitable choice for realizing green building industrialized development.In Practical Project, assembling frame structure uses relatively broad.
Reasonable connection and structural integrity in frame structure between prefabricated components have a significant impact to antidetonation, and are largely fixed
The anti-seismic performance of assembling frame structure.And frame structure central sill Column border node is the key link for influencing its anti-seismic performance, if
Rationally reliable interconnection technique is to improve the most important thing of assembled beam-column joints performance to meter.
In tradition full welding node of beam column, lower flange and web and welding of post scene on beam, although this type of attachment is
Rigid connection, but ductility of joint is poor, brittle break is easy to happen in earthquake, and need on-the-spot welding, leverages speed of application
Larger residual stress is easy tod produce simultaneously because bonding area is big with quality, influences the stress performance of node.
In tradition high-strength bolt tie-beam Column border node, beam-ends shrouding is fastenedly connected with box column by high-strength bolt, fastening
When worker need handle to reach in box column, when this form of construction work is to construction the fastening work of bolt make troubles, while spiral shell
Keyhole can weaken node short column, influence its stress performance.
In tradition bolted and welded connection node, lower flange and column site welding, web plate pass through shear plate and column on beam
Bolt, this connection type need on-the-spot welding, leverage speed of application and quality, and operational procedure is complicated, it is not easy to
Realize rigid connection.
Invention content
The present invention proposes a kind of novel complete prefabricated detachable assembling type beam-column connection, and its object is to overcome existing skill
The defect of art meets node items mechanical property, improves repair ability after rigidity, stability, bearing capacity and the shake of structural system,
It realizes bean column node to be rigidly connected, and realizes the assembling of structure, improve the assembled speed of component, fully adapt to assembled coagulation
The requirement of soil structure system and feature.
Technical scheme is as follows：
A kind of complete prefabricated detachable assembling type beam-column connection, by the prefabricated profile steel concrete column with cantilever beam section, in advance
The attachment device of steel reinforced concrete beam section and the two processed forms；
Prefabricated profile steel concrete column with cantilever beam section is by the I-steel of cross weld, ribbed stiffener, longitudinal reinforcement, stirrup and
Cantilever beam section forms.I-steel in prefabricated profile steel concrete column is welded to connect using criss-cross fashion；Longitudinal reinforcement is symmetrical
It is arranged in column on the outside of reinforcing bar, stirrup is arranged on the outside of longitudinal reinforcement；The edge of a wing of reinforcing bar is welded in reinforcing bar in column in cantilever beam section
The edge of a wing, in cantilever beam section in the column of the reinforcing bar edge of a wing corresponding position reinforcing bar edge of a wing inside be arranged ribbed stiffener, ribbed stiffener weldering
It is connected to the edge of a wing of reinforcing bar in column；
Attachment device includes upside U-shaped steel plate, downside U-shaped steel plate, beam conversion steel plate, column conversion steel plate and high-strength bolt.
Wherein, column conversion steel plate is respectively set in attachment device and cantilever beam and prefabricated steel reinforced concrete beam section link position and beam is converted
Steel plate；The cantilever beam section of prefabricated profile steel concrete column and prefabricated steel reinforced concrete beam section are carried out at the edge of a wing of shaped steel and web
It is welded to connect；Upside U-shaped steel plate is placed on downwards on the outside of I-steel again, downside U-shaped steel plate is placed on upwards outside the U-shaped steel plate of upside
Side is connected by Bolt.
The invention has the advantages that：
A. component processing is completed in factory, and precision and quality is easier to control；The connection of component then passes through construction
Site welding is realized with high-strength bolt Hybrid connections, it is easy to accomplish quick assembling；
B. since the edge of a wing uses the connection type of U-shaped steel plate, cantilever beam section edge of a wing thickness can be with common beam section edge of a wing thickness
Difference can realize that beam-ends reinforcement achievees the purpose that beam-ends plastic hinge, without adopting by thickening cantilever beam section edge of a wing thickness
It takes and adds the beam-ends strengthening measure such as cover board, ribbed stiffener and side plate, reduce difficulty of construction, avoid complicated caused by a plurality of weld seam
Stress field；
C. the installation method of bridging type reduces hoisting difficulty, accelerates construction speed.
