AI Technical Summary

Technical Problem

In existing technologies, the construction of new block infill walls in existing frame structure buildings has problems such as long construction period and insufficient collaborative performance between the infill wall and the frame structure, especially under dynamic loads, which can easily lead to problems in weak points of the structure.

Method used

The same-floor reinforcement structure is adopted. The main hanging column, bottom wall beam, partition layer and reinforcement frame beam are set in the floor with newly added masonry infill wall to form the same-floor reinforcement structure. The rubber layer and cement mortar layer partition layer improve the overall structure, carbon fiber composite material enhances the strength of the frame beam, and the main hanging column steel bars are connected to the reinforcement frame beam by tie bolts to achieve convenient installation.

Benefits of technology

It achieves efficient reinforcement without affecting the use of other floors during construction, improves the seismic performance and stiffness of the overall building structure, reduces the impact of earthquakes, enhances the safety of opening locations, and is easy to install and low in cost.

Abstract

This utility model relates to a same-floor reinforcement structure for adding a block infill wall to an existing frame structure floor slab. It includes at least two main hanging columns, a bottom wall beam, and a partition layer. One end of each main hanging column is connected to the reinforcement frame beam, and the other end is connected to the bottom wall beam. The reinforcement frame beam, main hanging columns, and bottom wall beam form a first installation area. The block infill wall is installed within the first installation area. A partition layer is installed between the bottom wall beam and the floor level of the construction floor. Compared with existing technologies, this utility model has the advantages of having the entire reinforcement structure located within the floor where the new block infill wall is added, without affecting the normal use and operation of other floors, avoiding the need for reinforcement construction on other floors; it is not connected to the structures of other floors, thus not affecting the structural safety of other floors; and the partition layer isolates the reinforcement structure of this floor from other floors, increasing the overall structural damping of the building and improving its seismic performance.
