[0002] With the rapid expansion of the city, the value of the land is getting higher and higher. Some buildings in the old city are built in a long time ago and the number of floors is low, so the land cannot be fully utilized. Demolition and reconstruction will inevitably cause a lot of waste of manpower and financial resources

Embodiment Construction
[0019] Such as Figure 1-2 As shown, the construction method of the connecting structure between the beam-column node of the jacket structure and the beam-column node of the original structure includes the beam-column node of the jacket structure 3, the beam-column node of the original structure 2, the rectangular or U-shaped reinforced node 4, the elastic backing plate 1 and the positioning block 6. Among them, the reinforcement node 4 is formed by expanding the beam-column node 3 of the jacket structure to the beam-column node 2 of the original structure, and there is a gap reserved between it and the beam-column node 2 of the original structure, and an elastic backing plate 1 is inserted in the gap, The elastic backing plate 1 is a rubber plate, a plastic plate or a polyurethane plate, and the area of the elastic backing plate 1 is not smaller than the area of the end faces of the beam-column joints 2 of the original structure. The elastic backing plate 1 is compressed ...

The invention relates to a construction method of a connecting structure of an outer sleeve structure beam-column joint and an original structure beam-column joint, and belongs to the technical field of seismic reinforcement. The construction method of the connecting structure of the outer sleeve structure beam-column joint and the original structure beam-column joint comprises a reinforced joint, an elastic liner plate and locating blocks. The reinforced joint is formed by the outer sleeve structure beam-column joint extending towards the inner side of the original structure beam-column joint, a clearance is reserved between the reinforced joint and the original structure beam-column joint, the clearance is filled with the elastic liner plate, the elastic liner plate is pressed tightly with the original structure beam-column joint and the reinforced joint, locating blocks are arranged below the rectangular reinforced joint and the elastic liner plate to prevent the rectangular reinforced joint and the elastic liner plate from falling off. The construction method of the connecting structure of the outer sleeve structure beam-column joint and the original structure beam-column joint is simple in structure of the connecting form, solves the technical problem that new buildings and old buildings bear horizontal load cooperatively on the connecting part of the outer sleeve structure beam-column joint and the original structure beam-column joint, and can be widely applied to adding story reformation of the old buildings.
Description
technical field [0001] The invention relates to a construction method for connecting a beam-column node of an outer structure and an original structure beam-column node, and belongs to the technical field of seismic reinforcement. Background technique [0002] With the rapid expansion of the city, the value of the land is getting higher and higher. Some buildings in the old city are built in a long time ago and the number of floors is low, so the land cannot be fully utilized. Demolition and reconstruction will inevitably cause a lot of waste of manpower and financial resources. In actual operation, the scheme of adding layers to the jacket frame is usually adopted, that is, to add layers on top of the original building while keeping the original building unchanged. Due to the separation of the old and new structures in this technical solution, the number of layers that can be added is generally more than three floors, which expands the building. area, saving land. At the ...
