Embodiment 1

[0040] This embodiment is to repair the weathering and defect of the clear water red brick wall. First, the clear water red brick wall is cleaned. Peel off the weathered cement mortar cover to expose the clear water red brick; then carefully take out the loose clear water red brick masonry, brush off the weathered silty matter on the surface of the masonry, and avoid disturbing other masonry to cause new loosening.

[0041] After cleaning the clear water red brick wall, carry out pointing treatment. First, pour high-strength epoxy mortar into the cracks of the clear water red brick masonry to increase the overall strength of the wall; then spray epoxy on the surface of the clear water red brick masonry Mortar for further reinforcement. Repair with masonry bricks that have been added to seal the openings of doors and windows after a certain historical period, or use polymer materials to solidify the surface of bricks, and use masonry powder to repair clear water red brick mason...

Embodiment 2

[0045] This embodiment is the restoration of the original appearance after the doors and windows of the clear water red brick wall are blocked. First, clean the surface of the brick wall and clean up the missing parts, and effectively protect the surrounding original masonry and stone pillars.

[0046] Then remove the wall, carefully remove the added blocks, and strictly prohibit disturbing other original masonry to cause new loosening. When demolishing, use an electric drill to drill a hole in the third layer of the upper part of the demolished wall to loosen it. After the outermost facing the first-skin brick, gradually loosen and extract the inner layer of smooth bricks, gradually loosen upwards from the extracted brick hole to extract the uppermost three-skin brick, remove all post-added masonry, and remove the masonry that touches the original wall. When removing the body, it should be loosened skin by skin from top to bottom before dismantling.

[0047] After the demoli...

Embodiment 3

[0049] This embodiment is repairing the intrusion and damage of plants on the clear water red brick wall. Before cleaning and repairing the clear water red brick wall, the invading plants are cleared. Firstly, carry out deterioration analysis, observe the changes of walls such as small trees and plant growth, and analyze the distribution of growth depth and root system; check the state of gaps or cracks in the wall, the size and depth of gaps, and check the damage status of the roof structure.

[0050] After completing the inspection work, start to clean up small trees and plants, cut off other branches of small trees, keep the main trunk, first carefully peel off the root system at the root, and then manually pull out small trees and plants, avoid disturbing the masonry structure during this process .

[0051] Then clean the root system, avoid disturbing the clear water red brick masonry, use a small amount of pressure water to wash the debris and root system in the gap, and us...

Abstract

The invention provides a repair technology for a plain red brick wall of a historical building, which aims to realize the authentic repair of the plain red brick wall of the historical building. The technology comprises the following steps: 1. the plain red brick wall is cleaned, and a weathered cement mortar covering layer is peeled to expose plain red bricks; 2. high-strength epoxy mortar is adopted to repair cracks of a plain red brick masonry; and 3. damaged pointing joints are treated and filled. The repair technology for the plain red brick wall of the historical building satisfies the international repair standard of the historical building, and adopts the prior materials and technologies to perform large area restored repair on the plain red brick wall; and the restored plain red brick wall of the historical building has historical features of the prior building and maintains the style of the prior historical building when seen from far, and can clearly distinguish which part is left in history when seen at a near distance, so the repair technology prevents the plain red brick wall from being destroyed.

Description

technical field [0001] The invention relates to the technical field of restoration of historical buildings, in particular to a restoration process of clear water red brick walls of historical buildings. Background technique [0002] The buildings made of clear water red brick walls are a common historical building, and they occupy a large proportion of the historical buildings left over in our country. However, due to the age-old problem, the skin of the brick wall of many old buildings has been loosened and blistered. This is because traditional materials have a breathing effect, and dust and dirt seal the moisture inside the masonry between the brick and the mask. If things go on like this, the moisture It will produce physical and chemical reactions with the surface of the brick masonry, and the surface will deteriorate and rot. [0003] In order to avoid further deterioration of the clear water red brick walls of historical buildings, their restoration has become an urg...
