AI Technical Summary
In the existing construction methods of sliding-type embedded parts of the damper, the embedded ribs are unreasonablely distributed in the wall, which affects the matching accuracy with the viscous damper position. The stability of the embedded ribs and threads is poor, resulting in connection failure. The anchor plate lacks sliding adjustment function or the sliding grooves and the embedded ribs are not accurately matched, which limits the flexibility and accuracy of position adjustment and reduces the shock absorption performance of the viscous damper.
By installing frame embedded ribs between the viscous damper and the shear wall and firmly connecting them with the embedded rib threads, combining the design of the sliding anchor plate and the sliding chute, the embedded member is ensured to match the position of the viscous damper and has a sliding adjustment function.
The precise matching of the embedded parts and the viscous damper positions is achieved, the shock absorption performance of the viscous damper is improved, and the stability and safety of the structure are ensured under different working conditions.

Abstract
Description
Technical Field
[0001] The invention relates to the field of building construction, in particular to a damper slider type embedded part construction method. Background Art
[0002] The damper slider embedded part is a device used in building structures or bridge engineering, mainly used to connect the structure and the shock absorption system. It is usually a device used to control and absorb vibration to improve the seismic performance of the structure, especially under the action of earthquakes, wind loads or other dynamic loads, to slow down or eliminate vibration.
[0003] The construction of the damper slider embedded parts must not only meet the design requirements, but also comply with relevant building codes and safety standards. The construction method clearly specifies how to follow these standards to ensure that the final structure has good seismic performance and safety. The construction method should be strictly operated in accordance with relevant technical specifications and standards to ensure that the structure can safely and stably play a shock-absorbing role in the future use process and meet the design requirements.
[0004] In previous building structures, there were often many problems with the design and installation of embedded parts for viscous dampers. Traditional embedded parts have a simple structure, usually only a single fixed form, and cannot be flexibly adjusted. The distribution of embedded reinforcement in the wall lacks rationality, and the stability of the threaded connection is difficult to ensure. This leads to the fact that in actual use, embedded parts often cannot accurately match the position required by the viscous damper, affecting the effective performance of the viscous damper. In addition, previous anchor plate designs often do not consider the function of sliding adjustment, or even if there is a similar design, the matching between the slide and the embedded reinforcement is not accurate enough to meet the requirements for position adjustment under different working conditions, thereby limiting the shock absorption effect of the viscous damper in the building structure. Summary of the invention
