It is society, science and technology, the inevitable outcome of economic progress, is to realize green building, the important channel of green construction.
In prefabricated concrete structure component, beam column can be effective using the big spacing high tensile reinforcement form of reinforcement of major diameter
Simplify and construct at connecting node, promote efficiency of assembling, greatly save the dosage of material, economize on resources, have significant economical
Benefit；Reinforcing bar and concrete amount are reduced simultaneously, can alleviate the pressure of the industries such as raw material production, processing and transport, and
Reduce the pollution to environment.And using Large-size rebar, it can reduce and muscle number of rows is indulged in test specimen, preferably play high tensile reinforcement
Advantage.
For the big spacing high tensile reinforcement form of reinforcement of major diameter, traditional anchorage style is for this precast concrete beam
Undoubtedly also huge challenge for column connected node, solves that reinforcing bar bending is difficult, and performance quality is difficult to ensure that, using the curved muscle of tradition
During anchorage style, because the increase of reinforced steel bar strength and diameter causes anchorage length larger, limited beam cross-section can not meet specification
It is required that major diameter high tensile reinforcement bent anchor length needed for space, become major diameter high tensile reinforcement precast concrete beam-column connection
Key, it is more significant in the popularization and application in assembly concrete frame structure.
State key research and development planning item (2016YFC0701402), problem are " the efficient arrangement of reinforcement of precast concrete
And Performance Design is theoretical ", the present invention is a subitem of the problem.The problem is for current prefabricated components arrangement of reinforcement complexity, peace
Packing quality is difficult to ensure that and efficiently reinforcement detailing and the phase such as high tensile reinforcement, Large-size rebar, big spacing arrangement of reinforcement, boundling arrangement of reinforcement
The theoretical incomplete problem of the design method answered, carried out the mechanical property of efficient arrangement of reinforcement precast concrete, fire resistance,
Thermal property, the suitable research for repairing performance and component Comprehensive Benefit Evaluation.
The content of the invention
The present invention provides a kind of fusiformis anchor head of major diameter high tensile reinforcement for reinforced concrete beam column node, in design
Performance is reasonable, is simple and efficient in construction, economically energy-saving, helps to realize that structure manufacture is simple, easy for installation and cost
Suitable design concept and construction method.
Technical scheme is as follows：
For the fusiformis anchor head of the major diameter high tensile reinforcement of reinforced concrete beam column node, including in anchor head top, anchor head
Portion and anchor head lower part are hexagonal prisms in the middle part of anchor head, and anchor head top and anchor head lower part are six terrace with edges, among fusiformis anchor head for through hole and
Equipped with internal thread, fusiformis anchor head outer surface is equipped with ring-shaped groove, and beam steel end point is equipped with external screw thread, fusiformis anchor head intermediate throughholes
The internal thread at place is together with the external thread bolt connection of beam steel end point.
The fusiformis anchor head of the major diameter high tensile reinforcement for reinforced concrete beam column node, further, fusiformis
Anchor head is added by machine after forging and molding to be formed or die casting forms.
The application of the fusiformis anchor head of the above-mentioned major diameter high tensile reinforcement for reinforced concrete beam column node, including as follows
Step：
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) be spirally connected fusiformis anchor head in beam steel end point；
4) the beam steel cage is sling into transverse direction, the column steel reinforcement cage is inserted into the beam steel end with fusiformis anchor head
It is interior, by the beam steel end with fusiformis anchor head together with column steel reinforcement cage binding；
5) in column steel reinforcement cage and beam steel cage peripheral hardware shuttering, casting concrete, completes construction thereto.
Beneficial effects of the present invention are：
When the 1st, using traditional bent bar anchorage mode, limited beam cross-section can not meet the major diameter high-strength steel of code requirement
Muscle bent anchor length；And the present invention is screwed in splice position using fusiformis anchor head, it is made to tighten together with reinforcing bar, solves big
The problem of bending of diameter high tensile reinforcement is difficult, and performance quality is difficult to ensure that, construction is simple is efficient, and it is strong can to give full play to reinforcing bar
Degree improves construction quality, reduces design, the construction anchorage length of the beam steel of reinforced beam, makes required anchoring space
Meet the requirement of beam cross-section size, saving steel reduces cost.
2nd, the present invention helps to realize structure for the Bar Anchorage of reinforced column and armored concrete beam connecting node
Part makes design concept and construction method simple, easy for installation and cost-effective.
3rd, fusiformis anchor head outer surface is equipped with ring-shaped groove, can strengthen the interlocking between fusiformis anchor head and concrete,
So as to preferably ensure joint behavior.
4th, fusiformis anchor head outer cross section is hexagon, and twisting rotation is not easy " to thread off " and be ensured of and has enough intensity on angle,
Hexagon has a good geometric properties, and orientation in office, direction can ensure that rotating path is most short when rotating.
