A treatment method for reinforcing bars of beam-column joints used for installing embedded parts of vibration isolators

Abstract

This application relates to a method for processing steel bars at beam-column joints used for installing embedded parts of vibration isolators, including the following steps: S1. Optimizing the steel bars of the frame columns, retaining the bent anchor bars at the corner points of the frame columns, and canceling the non-corner points of the frame columns The bent anchor reinforcement at the place should be changed to a straight anchor reinforcement. The anchorage length of the straight anchor reinforcement into the frame beam should not be less than the specification requirements; The position is disconnected, and the length of the disconnected full-length steel bar anchored into the frame column is not less than the specification requirement; S3, around the outline direction of the frame column, add a circle of reinforcing steel bar at the top of the frame column steel bar, and the reinforcing steel bar is fixed to the frame column steel bar. Knot. In this application, through the in-depth optimization of the ends of the steel bars of the frame columns and the steel bars of the frame beams, while meeting the design requirements and specification requirements, it can also ensure the installation accuracy of the embedded parts, so that the installation of the embedded parts can meet the accuracy required by the design.

Description

technical field [0001] The present application relates to the field of building vibration isolation, in particular to a method for processing steel bars at beam-column joints used for installing embedded parts of vibration isolators. Background technique [0002] At present, in buildings with a vibration isolation layer, the upper and lower reinforced concrete structures of the vibration isolation layer are disconnected as a whole, connected up and down through tensile vibration isolators and dampers, and there is no floor plate in the lower part of the vibration isolation layer. The embedded parts of the tensile type vibration isolator are installed in the frame column at the lower part of the vibration isolation layer. However, according to the structural requirements, the longitudinal reinforcement at the top of the frame column requires a bent anchor of 15d (d is the diameter of the steel bar). Since the bent anchor reinforcement at the top of the frame column is densely...

Problems solved by technology

[0003] In order to solve the technical problem that when the embedded parts are installed, the anchor bars on the embedded parts conflict with the bent anchor bars of the frame columns and the steel bars of the frame beams, and the installation of the embedded parts cannot be carried out.
