Construction and design method of tension type masonry wall reinforcing structure

By embedding L-shaped steel plates and high-strength steel wires at the corners of masonry walls, the tensioning reinforcement method solves the problems of difficult steel mesh insertion, weak pull-out resistance, and low reinforcement efficiency in existing technologies. This method improves the lateral load resistance and seismic performance of masonry walls while maintaining the building's appearance and adapting to different reinforcement needs.

AI Technical Summary

Technical Problem

Existing technologies for reinforcing masonry walls suffer from problems such as difficulty in inserting steel mesh into mortar joints, weak pull-out resistance, insufficient lateral shear resistance, low reinforcement efficiency, and increased wall thickness, resulting in limited improvement in seismic performance.

Method used

The reinforcement method combines high-strength steel wire and L-shaped steel plate. A groove is chiseled out at the corner of the masonry wall, filled with polymer mortar, and an L-shaped steel plate is embedded. The high-strength steel wire is inserted into the groove and locked to form an integral tension force system. A polymer mortar surface layer is applied to the surface, and a reinforcement system is constructed by combining it with a secondary connecting rope.

Benefits of technology

It improves the lateral load resistance and seismic performance of masonry walls, maintains the integrity of the building's appearance, enables targeted reinforcement, and adapts to the needs of different application scenarios.

Abstract

This invention relates to a construction and design method for a tensioned masonry wall reinforcement structure, comprising L-shaped steel plates embedded and fixed in the mortar joints at the four corners of one side of the masonry wall; two L-shaped steel plates are connected by high-strength steel wires; the ends of the high-strength steel wires are tightened and fixed to the L-shaped steel plates by steel wire rope lock heads; a polymer mortar surface layer is applied to one side of the masonry wall and covers the L-shaped steel plates and high-strength steel wires; this invention utilizes the combination of high-strength steel wires, L-shaped steel plates, and polymer mortar to improve the lateral bearing capacity and seismic performance of the masonry wall, significantly improving the overall stability of the masonry wall; the single-sided non-destructive reinforcement method avoids damage to the original masonry wall structure and maintains the original building appearance, meeting the needs of historical building restoration.
