Mounting method for buckle-type asymmetric flange plate seismic isolation support

Abstract

The invention relates to a mounting method for a buckle-type asymmetric flange plate seismic isolation support and belongs to the technical field of seismic isolation of constructional engineering. According to the mounting method, a buckle-type asymmetric combined connecting plate is used for connecting of the seismic isolation support, the upper portion of the asymmetric flange plate seismic isolation support is connected through an upper flange plate, and the lower portion of the asymmetric flange plate seismic isolation support is connected through combination of the buckle-type combined connecting plate and a cone-frustum-shaped flange plate. The buckle-type combined connecting plate is also used as a positioning plate, therefore, positioning pre-embedded plates can be omitted, and the positioning and mounting processes of the positioning pre-embedded plates are omitted; secondary polishing caused by the uneven top face of a poured lower buttress due to the low rigidity of the positioning pre-embedded plates can be avoided, and secondary grouting caused by uncompacted pouring and tamping of concrete can be also avoided; and the working efficiency and the mounting quality are improved, the engineering cost is also saved, and the seismic isolation support can be conveniently replaced in the future.

Description

technical field [0001] The invention relates to a method for installing a buckle-type asymmetrical flange plate shock-isolation support and belongs to the field of construction engineering shock-isolation technology. Background technique [0002] Earthquake is a very serious natural disaster. During the earthquake, the surface buildings will be distorted and deformed. When the earthquake is relatively strong, they will even collapse, causing huge economic losses and casualties. [0003] In order to ensure that buildings and bridges play their due functions in earthquakes and reduce earthquake disasters, as an effective structural shock-absorbing control technology, seismic isolation technology has received extensive attention from engineering and academic circles, and has been widely used in buildings and bridges at home and abroad. It has been widely used in earthquake resistance and other engineering results. "Seismic isolation" technology is to install a seismic isolatio...

AI Technical Summary

Problems solved by technology

[0005] Seismic isolators often use symmetrical flange plates (e.g. Image 6 The upper middle flange plate 12 and the lower flange plate 18) are connected, and the auxiliary positioning of the positioning embedded plate 17 will be used in the installation process. During the construction process, the rigidity is often small due to the thinner positioning embedded plate 17. The deformation of the positioning pre-embedded plate 17 leads to the dislocation of the embedded parts, which makes it impossible to install the seismic isolation support. In addition, the reserved concrete pouring hole in the middle of the positioning pre-embedded plate is small, resulting in poor exhaust during pouring concrete, which affects the lower support. The flatness and strength of the top surface of the pier, in order to ensure the installation quality of the seismic isolation bearing, additional secondary grouting is required for leveling, which is time-consuming and labor-intensive

In general, in order to ensure the flatness and levelness of the top surface of the lower pier, the positioning embedded plate is often not removed, so the economy is poor
