Description

A antidetonation reinforced structure for frame construction node
Technical Field
The utility model relates to a reinforced structure of frame construction beam column node, concretely relates to adopt node reinforced structure of outsourcing steel sheet.
Background
The first decade of the 21 st century has entered the global earthquake advanced stage, and a large number of reinforced concrete frame structures are destroyed and even collapsed after the earthquake. Most of the frame structure buildings are designed by adopting old specifications, only vertical loads are considered, and seismic design is not carried out, so that the core areas of frame columns, beams and nodes have small hoop matching rate, poor shearing resistance and ductility and insufficient seismic performance. Thus, a large number of non-ductile reinforced concrete frame structures that have not experienced an earthquake or have experienced only a low level of seismic action without significant damage in the seismic zone face a significant risk of collapse at higher levels of seismic action that may occur in the future.
Failure of beam-column joints in non-ductile reinforced concrete frame structures is often the primary cause of structural collapse in whole or in part, however it is not practical to push all such structures to rebuild. Therefore, effective reinforcement of the main vulnerable parts (beam-column joints) in the non-ductile frame structure is of great significance for avoiding collapse accidents in the future.
The reinforcing of the beam column joint can be realized by adopting an outer steel sleeve. In the prior art, a steel sleeve is generally formed by welding, for example, chinese patent application CN108798055A discloses a method for reinforcing a beam-column joint of a frame structure in which ECC is combined with an outer-coated steel plate, the outer-coated steel plate is pasted on the periphery of a cleared chiseled area, the steel plates are welded into an integral outer-coated steel sleeve, and the ECC prepared in advance is filled in a gap between the outer-coated steel sleeve and the chiseled area and then cured. The ECC can transmit the shearing force of the original structure to the outer-wrapping steel sleeve, so that the steel plate and the original structure bear the shearing force together. In addition, there are also angle steels or corbel structures that are reinforced with steel plates, but the steel plates are all welded on site. In the technical scheme, the beams and columns of the nodes are reinforced in a mode of wrapping the steel sleeves externally, but on one hand, the wrapped steel sleeves are formed by welding steel plates on site, the site construction consumes long time, and the construction is difficult in some scenes; on the other hand, although the shear force bearing capacity of the existing beam and column can be enhanced to a certain degree through steel wrapping, the stress transmission mode of the beam and column cannot be adjusted, and the reinforcing effect is influenced.
