Embodiment Construction

[0013] The core principle of the present invention is: by adding reinforcement mesh sheets on one side of the wall and connecting them with L-shaped wall-through steel bars, the steel bars and the wall form a whole, thereby improving the seismic performance of the wall.

[0014] Such as figure 1 As shown, the existing single-side reinforced seismic reinforcement method of the masonry structure of the present invention, the main steps are as follows:

[0015] 1) After the original wall is cleaned, the mortar joints 5 between the wall blocks 6 on both sides are re-pointed, the depth of each side is ≥30mm, and the strength of the caulking mortar is M10.

[0016] 2) Make φ6300 (vertical arrangement of steel bars 3) × 150 (horizontal arrangement of steel bars 4) welded steel mesh pieces on one side of the wall.

[0017] φ6300×150 means: the steel bar diameter of the steel mesh sheet is 6mm, the vertically arranged steel bar spacing is 300mm, and the horizontally arranged steel bar...

Abstract

The invention relates to a unilateral-ribbing anti-seismic reinforcing method for an existing brickwork structure, and the method comprises the following main steps: 1. after the traditional wall body is cleaned, jointing a mortar joint between wall body brickworks on two sides; 2. on the single outside of the wall body, manufacturing a welded rebar netting of a vertically-arranged rebar*laterally-arranged rebar; 3. connecting the rebar netting on the single side and the wall body into a whole by a plurality of L-shaped wall penetrating rebars, wherein the plurality of wall penetrating rebars are arranged at equal interval in a plum blossom shape; and 4. manufacturing a cement plaster surface layer on the outer side of the rebar netting. In the unilateral-ribbing seismic reinforcing method, the rebar netting is additionally arranged on the single side of the wall body and is connected by the L-shaped wall penetrating rebars, and the rebars and the wall body form a whole so as to improve the anti-seismic performance of the wall body.

Description

technical field [0001] The invention relates to a single-side reinforcement method for a masonry structure for improving the seismic performance of the masonry structure. Background technique [0002] In some existing buildings or historical buildings, due to the design theory, building materials, and construction conditions at that time, the building materials used, construction quality, structural seismic bearing capacity, and structure do not meet the current code requirements. Moreover, the brick walls in these buildings are generally load-bearing walls, which have a great impact on the safety of the structure. The mortar strength of many walls is low, and the strength of some mortars is even lower than the minimum requirements specified in the code. The mortar has become crisp and falls off, which seriously affects the bearing capacity of the brick wall and is not conducive to earthquake resistance. The wall must be reinforced before it can continue to be used. In the ...
