With in formula structure design it has to be remarked that one of key position.
State key researches and develops planning item (2016YFC0701402), and project is " the efficient arrangement of reinforcement of precast concrete
And Performance Design is theoretical ", the utility model is a subitem of the project.The project is multiple for current prefabricated components arrangement of reinforcement
Miscellaneous, installation quality is difficult to ensure and the efficient reinforcement detailing and corresponding such as high tensile reinforcement, Large-size rebar, big spacing arrangement of reinforcement
The theoretical incomplete problem of design method has carried out the mechanical property of efficient arrangement of reinforcement precast concrete, fire resistance, thermal technology
Performance, the suitable research for repairing performance and component Comprehensive Benefit Evaluation.
Utility model content
The utility model provides a kind of wedge-shaped intermediate plate anchor head of the reinforcing bar for reinforced concrete beam column node, solves pre-
Concrete frame structure center pillar area of section processed is small, and anchorage length of steel bar cannot be met the requirements, cause node cost of manufacture high and
Problem complicated for operation.
The technical solution of the utility model is as follows：
The wedge-shaped intermediate plate anchor head of reinforcing bar for reinforced concrete beam column node, including anchor ring and three intermediate plates, the anchor
Ring is in truncated cone, and spiral non-slip groove is equipped with outside the anchor ring, is with gradient through-hole inside the anchor ring；Three folders
Plate shape is identical, and three intermediate plates form wedge-shaped annular body；The intermediate plate is internally provided with spiral groove；Three intermediate plates wedge the anchor
Between ring and the beam steel of assembly concrete beam.
The wedge-shaped intermediate plate anchor head of the reinforcing bar for reinforced concrete beam column node, further, the anchor ring and
Intermediate plate is formed by forging or die casting forms.
The application of the wedge-shaped intermediate plate anchor head of the above-mentioned reinforcing bar for reinforced concrete beam column node, includes the following steps：
1) column tie-bar is vertically sleeved on banded composition column steel reinforcement cage on upright column reinforcing bar；
2) beam stirrup is vertically sleeved on banded composition beam steel cage on upright beam steel, and beam steel end point, which reserves, takes
Connect anchorage length；
3) anchor ring is sleeved on beam steel end point, and three intermediate plates are wedged between the anchor ring and beam steel；
4) the beam steel cage is sling into transverse direction, the column steel will be inserted into the beam steel end of wedge-shaped intermediate plate anchor head
In muscle cage, the beam steel end with wedge-shaped intermediate plate anchor head is bound together with the column steel reinforcement cage；
5) in column steel reinforcement cage and beam steel cage peripheral hardware shuttering, casting concrete, completes construction thereto.
The beneficial effects of the utility model are：
1, the use of the utility model solves the problems, such as to cannot be satisfied anchorage length requirement since column section is small, big straight
The connection of diameter high tensile reinforcement and anchor ring uses plug-in type intermediate plate, and wedge-shaped intermediate plate anchor head anchorage length in reinforced column is short,
Bending reinforcing steel bar is avoided, difficulty of construction is reduced；Wedge-shaped intermediate plate anchor head and concrete surface product are big, and cementitiousness is strong, high construction efficiency
Succinctly.
2, the wedge-shaped intermediate plate anchor head of the utility model gives full play to the advantage of wedge shape, when beam steel stress slides outward,
Wedge-shaped design gives full play to advantage, and anchor ring small end moves intermediate plate and generates limitation, and intermediate plate is further to the outside cunning of beam steel
It moving and generates limitation, sliding is bigger, and limitation is bigger, meanwhile, the interlocking of indentation enhancing beam steel and intermediate plate inside intermediate plate is prevented
Only beam steel is detached from slipping and skids off, have improve joint behavior, it is easy for construction, shorten working hour and be easy to industry metaplasia
The advantages that production.
3, the utility model can improve the quality of prefabricated assembled concrete frame construction；Reduce reinforcing bar usage amount, symbol
Close sustainable development rule.
4, the wedge-shaped design of anchor ring increases the contact area of anchor ring and reinforced column, while the spiral outside anchor ring
Indentation can greatly enhance the caking property of anchor ring and reinforced column, and wedge-shaped intermediate plate anchor head is prevented to be detached from loading process
Reinforced column.
5, the limitation by wedge-shaped intermediate plate anchor head to the sliding of major diameter high tensile reinforcement, greatly reduces prefabricated assembled
The bar splicing anchorage length of concrete connecting node improves major diameter high tensile reinforcement in prefabricated assembled concrete frame section
Utilization rate in point.The use of wedge-shaped intermediate plate anchor head can avoid the bending of major diameter high tensile reinforcement, shortens working hour, reduces cost,
Facilitate construction；Prefabricated assembled concrete column is can be applied to, the use scope of major diameter high tensile reinforcement has been expanded；And the wedge grip
Piece anchor head moulding is simple, strong applicability, and by setting the modularization node of several canonical forms and scale, modularization may be implemented
Production, is conducive to building industrialization, has vast potential for future development and design application value.
