Description
Technical field
The utility model relates to a kind of reinforcing bar grouting connection structure more particularly to a kind of two reinforcing bars are stitched together
Splicing construction belongs to assembled architecture field.
Background technique
Prefabricated assembled concrete structure, usually by some other Accessory Members such as prefabricated column, beam, plate and precast stair
Composition.Compared with foreign countries, the PC structure type and engineering method in China are started late, and PC rate is lower.Restrict what PC structure was promoted
Key factor is how to guarantee effective node connection type, how by suitable connection type make PC structure closest to
Cast-in-place concrete structure makes PC structure can guarantee that necessary bearing capacity, energy dissipation capacity are the important topics of current structure design.
Precast concrete, English: precast concrete, thus claim PC component, refer in the factory by standardization,
The concrete product of mechanized manner processing.Corresponding tradition cast-in-place concrete needs building-site molding, shows
Field casting and scene maintenance.Precast concrete is widely used in the fields such as building, traffic, water conservancy, plays the part of in national economy
Drill important role.
Compared with cast-in-place concrete, the precast concrete of the factorial production has many advantages:
Safety: for construction worker, metastable working environment is safely than complicated site operation in factory
Number is higher；
Quality: the quality and technique of building element can be controlled preferably by mechanization production；
Speed: the standardization of preform sizes and characteristic can dramatically speed up installation speed and architectural engineering progress；
Cost: compared with conventional on-site molding, the mold in factory can be used with repetitive cycling, and overall cost is lower；Machine
The demand that tool metaplasia is produced to artificial is less, with the continuous raising of cost of labor, the prefabricated component cost advantage meeting of large-scale production
It is further obvious.
Environment: it is significantly reduced using the construction site field operation amount of prefabricated component, dust pollution, noise pollution are significantly dropped
It is low.
The scene splicing of prefabricated components is most important work in assembled in situ, is needed in splicing prefabricated by two
Just connecing for element joints is stitched together, and the connection of two reinforcing bars is generally by sleeve grouting connection, sleeve grouting connection
Refer to and be inserted into reinforcing bar in pre-buried metal sleeve in precast concrete, and is poured in strength cement-based grouting material and the steel realized
Muscle connection type.The key of this connection type is that grouting slurries used have stronger cementitiousness, can be by sleeve and steel
Muscle is securely attached to together, to realize that external force suffered by one section of reinforcing bar can smoothly pass to the reinforcing bar of the other end.
The centre that reinforcing bar is in sleeve is not can guarantee in the prior art, this will affect pouring quality, to influence
The connection reliability of reinforcing bar and sleeve.
Utility model content
The purpose of the utility model is to provide a kind of reinforcing bar grouting connection structures, to solve not can guarantee steel in the prior art
Muscle is in the centre of sleeve, to influence pouring quality, and then the problem of the connection reliability of influence reinforcing bar and sleeve.
In order to achieve the goal above, the utility model adopts the following technical solution:
A kind of reinforcing bar grouting connection structure, including connection sleeve, the both ends for connecting hub internal bore are inserted with the first steel respectively
Muscle and the second reinforcing bar are provided with end cover at the both ends of connection sleeve, connect and be provided with grout pipe at the both ends of sleeve, described
The first reinforcing bar and the second reinforcing bar on be provided with along the respective bracket radially extended, the bracket of two reinforcing bars is both supported upon connection
On the inner hole wall of sleeve.
The end of first reinforcing bar and the second reinforcing bar is folded to be located at together.
First reinforcing bar and the second reinforcing bar be folded to be located at end head together and is provided with the laciniation being mutually twisted.
There is gap between the end face of first reinforcing bar and the second reinforcing bar.
Having gap between the end face of first reinforcing bar and the second reinforcing bar is 1-5cm.
It is provided on the utility model the first reinforcing bar interconnected and the second reinforcing bar along the respective branch radially extended
Frame, the bracket of two reinforcing bars are both supported upon on the inner hole wall of connection sleeve, and such two reinforcing bar, which can consolidate, to be supported in sleeve, can guarantee
Effective grout gap between reinforcing bar and connection sleeve, bracket can also further increase reinforcing bar and connect secured between sleeve
Property.
First reinforcing bar and the second reinforcing bar of the utility model be folded to be located at end head together and is provided with the sawtooth being mutually twisted
The connection between the first reinforcing bar and the second reinforcing bar can be enhanced in shape structure, laciniation, and can increase the first reinforcing bar and
Connectivity robustness between two reinforcing bars and the concrete of grouting.
