Embodiment 1

[0024] A method for replacing mortar of a masonry structure for reinforcing mortar joints, comprising the original masonry structure wall body 1, the original low-grade mortar 2 in the original mortar joints and the newly backfilled high-grade mortar 3, the replacement method of the mortar joints adopts The method of replacing the long-length mortar joints on both sides of the wall, that is, the two ends of the original mortar joints in the horizontal direction of the wall thickness are cut horizontally along the longitudinal direction of the original masonry structure wall 1, the original low-grade mortar 2 is removed, and the high-grade mortar is backfilled. Mortar 3 is used to improve the compressive and shear resistance of the masonry structure, while the original low-grade mortar 2 in the middle part of the wall thickness direction remains unchanged. Among them, the wall blocks are solid bricks, the original low-grade mortar 2 has a strength grade of M2.5 or M5.0, and the ...

Embodiment 2

[0033] The wall block in this embodiment is a hollow block, the strength grade of the original low-grade mortar 2 is Mb2.5 or Mb5.0, and the strength grade of the high-grade mortar 3 is Mb7.5, Mb10 or Mb15. Other structures and methods are the same as in Embodiment 1, and will not be described in detail here.

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...
