The design concept and construction method of cost-effective.
The technical solution of the utility model is as follows：
The fusiformis anchor head of major diameter high tensile reinforcement for 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 is six terrace with edges with anchor head lower part, be among fusiformis anchor head 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 it is 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) it is 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, the beam steel end with fusiformis 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：
When 1, using traditional bent bar anchorage mode, limited beam cross-section cannot be satisfied the major diameter high-strength steel of code requirement
Muscle bent anchor length；And the utility model is screwed in splice position using fusiformis anchor head, it is made to tighten together with reinforcing bar, solves
The problem of bending of major diameter high tensile reinforcement is difficult, and performance quality is difficult to ensure, construction is simple is efficient, can give full play to reinforcing bar
Intensity improves construction quality, reduces design, the construction anchorage length of the beam steel of reinforced beam, keeps required anchoring empty
Between meet the requirement of beam cross-section size, saving steel reduces cost.
2, the utility model is used for the Bar Anchorage of reinforced column and armored concrete beam connecting node, contributes to reality
Existing component makes simple, easy for installation and cost-effective design concept and construction method.
3, fusiformis anchor head outer surface is equipped with ring-shaped groove, can reinforce the interlocking between fusiformis anchor head and concrete,
To preferably ensure joint behavior.
4, fusiformis anchor head outer cross section is hexagon, and twisting rotation is not easy " to thread off " and be ensured of have 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.
