Description
Technical Field
The utility model relates to a beam column core space stirrup quick connect node.
Background
The general concrete frame structure specification is bigger, and the roof beam is high and deep, especially adopts "heavy beam method" construction, and the beam column core area crisscross reinforcing bar is more, and is denser. The beam column reinforcing bar diameter is great, the stirrup generally overlaps earlier on vertical post reinforcing bar, the layering penetrates beam reinforcing bar one deck, often can the card die when whole sinks or partially sinks, sink not go at all, bring very big troubles for the construction, construction unit constructor often can delete or reduce the stirrup so that the space of nuclear core district is enlargied, the resistance is little, nuclear core district beam reinforcing bar sinks conveniently, caused the design originally should encrypt the stirrup at beam column nuclear core district, but now by construction unit because the difficult problem that construction process can't solve puzzles. Causing a common problem in construction quality.
Because the problem is more complicated, the problem of hooping and reinforcing in the core area of the beam column is described in several aspects:
1. from the viewpoint of mounting process
For a large-scale frame beam structure, the sections of columns and beams are large, the span is small, the hoisting range of a tower crane is limited, if the template beams are all opened, and reinforcing steel bars are installed firstly, the windows left in a construction area are too many for the large-scale frame beam structure, and constructors walk, carry and hoist the large-scale frame beam structure too unsafe. Therefore, after the template is laid, a temporary support is arranged, a beam rib is bound and a stirrup or a reinforcement cage in a core area is arranged by adopting a 'beam sinking method', even if the 'sedimentation' of the stirrup is difficult without binding, the 'sedimentation' of the stirrup is not enough, but the 'sedimentation' of the stirrup is not enough, and the distortion and the overlapping are serious. And can not be banded again. Therefore, the stirrups are usually deleted in the construction process, and the stirrups in the core area cannot meet the design and specification requirements due to the difficulty in sedimentation.
2. From the viewpoint of the damage to the structure
The earthquake damage investigation reports that the serious part of the frame structure earthquake damage mostly occurs at the joints of the frame beams and columns. The reason is that the bending moment, the shearing force and the axial force at the node are large, the stirrup configuration of the column is insufficient or no stirrup exists, the concrete is cracked and peeled off under the combined action of the bending shear, and the reinforcing steel bar is pressed and bent under the action of the longitudinal force. Repair of such damage is difficult. Therefore, the hooping for the beam-column joint of the encrypted frame can enhance the constraint effect on the concrete, not only can enhance the deformation capacity of the member, but also can improve the strength of the concrete and the like.
3. The current adjustment and improvement solution
The method is characterized in that the stirrups in the core area of the beam column are twisted and deformed, and the stirrups which are not added or deleted are adopted, so that the template is opened for adding or replacing, and the stirrups are added or replaced by adopting open stirrups or electric welding stirrups. The connection is rough, the size cannot be controlled, the connection is unreliable, and some connections only deal with the rectification and rectification, so people feel not real and imperfect. But better than not.
However, as can be seen from the above aspects, the beam-column core region of the frame structure is a critical part of the whole structure. The loss and improper connection of the stirrups can not meet the design requirements, but also can not meet the construction quality acceptance standard requirements.
SUMMERY OF THE UTILITY MODEL
