Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of wall repair, and particularly to a non-demolition repair method for the exterior wall of high-rise buildings. Background Art
[0002] With the acceleration of the urbanization process, the construction industry in China has developed vigorously, with an increasing number of newly built buildings and a more widespread application of exterior wall insulation. However, in the actual application process, due to reasons such as the building structure form, climatic conditions, system materials, construction technology, and construction management, the wall is prone to several problems such as hollowing, cracking, leakage, moisture and frost heaving, condensation, and peeling. In recent years, there have been frequent news reports of large-area cracks and peeling on the exterior wall surface, resulting in losses of life and property.
[0003] The conventional repair method in the market is to remove the original building insulation system and then re-do the wall insulation system and finish. This method is cumbersome in construction, causing many troubles and inconveniences to the lives of the residents in the building. At the same time, the removal process will also lead to potential safety hazards of the original exterior wall insulation materials falling from a height, and the transportation and subsequent treatment of the removed construction waste are very difficult, resulting in a high project cost. As a result, when there are problems with the exterior walls of a large number of existing externally insulated buildings, timely and effective treatment cannot be carried out.
[0004] The wall is a vertical component of building physics. Generally, it does not store water, accumulate water, and is not prone to leakage. However, factors such as rough construction, improper material selection, poor material quality, improper user use, or poor management can cause cracks and damage to the wall, resulting in leakage. At this time, the cracks need to be repaired. Some of the existing repairs are carried out by demolishing the wall and rebuilding it. This method has a large amount of construction work, is troublesome to operate, has a high cost, and a long cycle. Therefore, we propose a non-demolition repair method for the exterior wall of high-rise buildings to solve the above problems. Summary of the Invention
