Method of replacing mortar in mortar joint for masonry structure reinforcement

Abstract

The invention relates to a method of replacing mortar in a mortar joint for masonry structure reinforcement and belongs to the technical field of seismic hardening of houses. The method relates to an original masonry structure wall, the original low-grade mortar in the original mortar joint and newly backfilled high-grade mortar. The method is a method for replacing mortar in pass-length type mortar joints in the two sides of the wall and comprises the steps of tunneling through the two ends, in the transverse thickness direction of the wall, of the original mortar joint horizontally in the longitudinal direction of the original masonry structure wall, removing the original low-grade mortar, backfilling the high-grade mortar to improve the compression resistance and shearing resistance of a masonry structure, and reserving the middle part, in the transverse thickness direction of the wall, of the original low-grade mortar. According to the method, the compression resistance and shearing resistance of the masonry structure are improved by replacing the low-grade mortar in the wall with the high-grade mortar, the safety of the houses is guaranteed, construction cost is low, and original space is not occupied after wall reinforcement. The method can be widely applied to house reinforcement.

Description

technical field [0001] The invention relates to a mortar replacement method for strengthening a masonry structure and belongs to the technical field of building anti-seismic reinforcement. Background technique [0002] With the development of human society, the improvement of productivity level and the advancement of science and technology, the design standards of building structures are constantly improving, and people are paying more and more attention to the safety of houses. Faced with the large number of masonry structures existing today, more reinforcement methods have emerged. Facing the advantages and disadvantages of various reinforcement methods, choosing a reasonable, effective, and economical reinforcement method has become the basic principle for most residents. Require. The present invention is based on the content of formula (7.2.7-2) in the "Building Seismic Design Code" and thinks that the size of the mortar strength in the mortar joint of the masonry struc...

Problems solved by technology

[0003] In order to solve the problem that the seismic performance of the existing masonry structure buildings can no longer meet the standard requirements and the cost of other reinforcement methods is high, the present invention proposes a method for replacing mortar for masonry structure reinforcement mortar joints. Mortar with a lower grade is replaced with a mortar with a higher grade, the purpose is to improve the compressive and shear resistance of some mortars, and effectively improve the compressive and shear resistance of the entire masonry
