The structure of the embedded prestressed prefabricated frame to reinforce the original frame

Abstract

The invention discloses a structure for reinforcing an original frame with an embedded prestressed assembled frame. The embedded frame structure is located in the plane of the original frame structure, the embedded prefabricated beams are located on the upper and lower sides of the original frame beam, and the embedded prefabricated columns are located in the original frame. On the left and right sides of the column, the prestressed tendons pass through the embedded frame beams and the embedded frame columns; the embedded frame beams and the embedded frame columns are respectively connected with the original frame by studs, and the grouting material is filled in the connected gaps. ; The ends of inline frame beams and inline frame columns are partially weakened, and rubber pads are placed at the weakened positions; the elastic modulus of the rubber pads is lower than that of the inline frame members, and the ductility is higher than that of concrete, and the rubber pads are fixed with the inline frame structure by structural glue. . The additional integral embedded frame structure of the present invention not only contributes to the seismic capacity of the reinforced integral structure with its own seismic bearing capacity and energy dissipation capacity, but also can improve the stress state and deformation mode of the original frame structure, so that the seismic resistance of the original structure can be improved. capabilities are more fully utilized.

Description

technical field [0001] The invention relates to the field of anti-seismic reinforcement of civil engineering, in particular to a structure in which a prestressed assembled frame is embedded to reinforce an original frame. Background technique [0002] The reinforcement of the additional integral substructure is to use the cooperative work of the additional integral substructure and the original structure, which can not only effectively improve the overall stress state of the structure, improve the seismic performance of the structure, but also try not to interrupt the normal use of the building structure during the reinforcement construction. It can also create rich architectural effects in combination with the specific conditions of the building, and is an economical, reasonable and efficient structural system reinforcement structure. [0003] At present, most of the additional substructure reinforcements require cast-in-place operation of the substructure, which will cause...

AI Technical Summary

Problems solved by technology

[0003] At present, most additional substructures need to be cast-in-place for substructures, which will cause pollution and noise, and the construction period is complicated and long

In addition, the reinforcement of the additional substructure is mostly externally pasted. Since it is not on the same plane as the original structure, there will be problems such as connection and cooperative work, and the external aconite structure affects the aesthetics of the structure to a certain extent.
