The invention discloses a method for reinforcing a modified outer wall of a dwelling, and relates to the technical field of concrete processing. The method comprises the following steps: step 1, cleaning a wall surface with water and soapy water, and carrying out surface treatment; secondly, cement paste is used for pressure grouting, and cracks of the outer vertical face of the old wall are repaired; 3, drilling holes in the original outer wall according to the quincunx layout, and configuring steel tie bars in the holes; 4, two-way reinforcing meshes are laid on the two sides tightly attached to the original outer wall, and the reinforcing meshes are tensioned and fixed through the two ends of the steel tie bars; fifthly, after reinforcement is completed, formwork erecting is conducted on the outer side of the reinforcing mesh, concrete grouting materials are adopted for pouring the inner lining wall and the outer lining wall, a plywood wall is formed after pouring, and meanwhile wall holes are filled with the concrete grouting materials; sixthly, after the reinforcing materials are installed, a heat preservation isolation layer needs to be installed; and 7, the lining wall and the inner buttress columns are poured at the same time during construction, and the rigidity and the overall anti-seismic property of the wall are improved.

本发明公开了一种民居改造外墙加固方法，涉及混凝土加工技术领域。该民居改造外墙加固方法，包括以下步骤：步骤一：通过水和肥皂水清洗墙面并进行表面处理；步骤二：用水泥浆压力灌浆,修补老墙外立面裂缝；步骤三：在原有外墙上按照梅花形布局进行钻孔，孔内配置拉结钢筋；步骤四：在紧贴原外墙两侧铺设双向钢筋网片，钢筋网片通过拉结钢筋的两端拉紧固定；步骤五：配筋完成后，在钢筋网片外侧进行支模，采用混凝土灌浆料浇筑内外衬墙，浇筑后形成夹板墙，同时混凝土灌浆料将墙孔灌满；步骤六：在安装加固材料后，需要进行保温隔离层的安装；步骤7：内衬墙施工时与内扶壁柱同时浇筑，提高墙体刚度与整体抗震性能。
