Description
Technical field
The invention belongs to mechanical connection technique of reinforcement field more particularly to a kind of steel concrete supporting structure and its installation sides
Method.
Background technology
Steel concrete supporting is a new reinforcing steel bar Joining Technology, " the third generation reinforcing bar being referred to as after binding, electric welding
Connector " has many advantages, such as strength of joint higher than parent material of reinforcement rebar, speed than being welded fast, pollution-free, saving steel.It is common at present
There are three types of steel concrete supporting methods：(1) extrusion socket joint connector makes connection reinforcing bar that plasticity occur with sleeve by extruding force
It deforms and is closely engaged, but extrusion equipment is heavier, site operation is inconvenient；(2) taper thread jointing passes through steel bar end
It is engaged with the tapered thread of connector end and forms jointing, taper thread silk head head prefabrication, site operation only needs torque
Spanner, it is easy to operate, but taper thread jointing quality is not sufficiently stable, and it is not high to be generally used for joint quality class requirement
Situation；(3) straight thread joint is the newest trend in the world of the strong ties such as reinforcing bar, and joint quality is reliable and stable, bonding strength
Height, convenient and quick construction, existing taper thread joint advantage easy for construction, and the unstable disadvantage of quality of connection is overcome,
Therefore the appearance of straight thread joint technique brings qualitative leap to rebar connecting technology.
Common single sleeve straight screw connection or taper thread connection need docking reinforcing bar that can be freely rotated, and pass through and reverse steel
Muscle ensures mutually to hold out against in sleeve middle position, can improve quality of connection but also reduce the residual deformation of connector.But for pre-
Concrete component and reinforcing bar tied framework processed is fixed because reinforcement location is with precast concrete or reinforcing bar tied framework position, single
Root reinforcing bar can not be accomplished to be freely rotated.It is usually connected at one section when practice of construction and lengthens silk head on reinforcing bar, in advance branch sleeve
The drawbacks of screw-in lengthens silk head, and after reinforcing bar contraposition, branch sleeve is screwed in by lengthening silk head in another reinforcing bar, such method
It is that branch sleeve Smooth Rotation between connecting reinforcing bar, can not apply torque makes reinforcing bar hold out against, the residual deformation of this connection is very
Greatly, joint quality it is difficult to ensure that.
Building industrialization is the development trend of current Building Trade in China, is the important of realization " four sections, one environmental protection " green building
Step.The important feature of building industrialization is exactly that most of component is prefabricated in the factory, and simple connecting structure is only done just in scene
Structure stress requirement can be met, the bar connecting of prefabricated components must be completed at the scene, and the joint connection in site of prefabricated components reinforcing bar is normal
The method seen has：Reinforced bar sleeve grouting connection and reinforcing bar slurry anchor overlap joint connection.The working mechanism of reinforced bar sleeve grouting jointing
It is to give grouting material in grout sleeve to have higher compression strength, while grouting material has micro-expansibility, when slurry encounters sleeve
Constraint when, generate larger pressure in slurry and sleeve lining, and thus pressure generates frictional force to transmit the axial direction of reinforcing bar
Stress, the position accuracy requirement that sleeve grouting is connected to branch sleeve and reinforcing bar is very high, and grouting material is required to have mobility
And micro-expansibility, difficulty of construction is very big, is the bottleneck of building industrialization fast development.Reinforcing bar starches the connection of anchor overlap joint and reinforced bar sleeve
Grouting connects similar, the pre-buried bellows in concrete, and after concrete strength reaches requirement, reinforcing bar passes through bellows, then will
High intensity microdilatancy grouting material pours into bellows maintenance, and the axis of reinforcing bar is transmitted using the extruding force that bellows confined concrete generates
Power.Same reinforcing bar slurry anchor overlap joint connection also has the features such as difficulty of construction is big, grouting material quality is difficult to control.
Invention content
