Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering, and particularly relates to an installation and positioning device for seismic isolation bearings. Background Technique

[0002] The seismic isolation technology is to set a seismic isolation layer between the building foundation and the superstructure, separating the superstructure from the substructure. When an earthquake occurs, the seismic isolation bearings and viscous dampers in the seismic isolation layer absorb and buffer a large amount of seismic energy, reducing the damage of the earthquake to the superstructure of the building. This technology has obvious shock absorption effect and has the characteristics of economy, safety, energy saving, etc., and has been widely applied in high-rise building projects in high-intensity earthquake areas.

[0003] At present, the installation of seismic isolation bearings includes positioning in three directions of X, Y, and Z. The traditional positioning method of seismic isolation bearings is to weld four positioning steel bars at the corner main bars of the lower pier, weld nuts on the steel bars, sleeve the screw into the nut, and adjust the bottom elevation of the lower embedded steel plate with the screw. When adjusting and fixing the elevation of the Z axis, it will cause the X and Y to also shift, resulting in the inclination and deviation of the bearing positioning; moreover, the embedded anchor bars are inserted into the dense steel bar area of the lower pier, and the embedded anchor bars are inside the column bars, making it difficult for workers to weld and reinforce, and it is easy to be displaced; when vibrating the concrete with a vibrator, the positioning steel bars of the seismic isolation bearing lack multi-directional constraints and shift, resulting in the installation of the seismic isolation bearing deviating from the designed bearing center position.

The first right-angle corner bracket includes two first side plates that are perpendicular to each other and both perpendicular to the horizontal plane. On one of the first side plates, there is an X-direction chute extending along the X-axis direction on the horizontal plane, and on the other first side plate, there is a Y-direction chute extending along the Y-axis direction on the horizontal plane. A second right-angle corner bracket is movably connected to each first right-angle corner bracket. The second right-angle corner bracket includes two second side plates that are perpendicular to each other and both perpendicular to the horizontal plane. On at least one of the second side plates, there is a Z-direction chute extending along the vertical direction. On both of the second side plates, there is a first screw perpendicular to the surface of the side plate. The first screws on the two second side plates are respectively slidably connected in the X-direction chute or Y-direction chute on the two first side plates. At the four corners of the bottom of the lower embedded steel plate, a set of anchor bars extending vertically downward are provided respectively. A second screw perpendicular to the anchor bar is connected to the anchor bar. The second screws on the anchor bars at the four corners of the bottom of the lower embedded steel plate are respectively slidably connected in the Z-direction chutes on the four second right-angle corner brackets. Nuts are respectively threadedly connected to the first screw and the second screw.

[0007] Preferably, on both of the second side plates of the second right-angle corner bracket, there is a Z-direction chute extending along the vertical direction.
