Abstract

The article presents the results of performed visual and instrumental surveys that allow to clarify and expand information on the structural design of the walls of the building, the nature of the damage and the cause of their origin. In order to obtain a more complete initial information on the surveyed object, visual and instrumental surveys were additionally carried out to clarify and expand information on the structural design of the building walls, the nature of the damage and the cause of their origin. Project-technical, executive and acceptance documentation for construction, as well as acts of survey of hidden works on the site are absent. By instrumental methods it is established that there is a gap between the surface of the main wall and the facing brick layer and the deviation of the facing layer from the vertical surface. As a result of inspection of the opened window slopes, it is established that the mesh protruding from the main masonry does not enter the lining seams but is bent into the gap. Therefore, the facing layer of masonry, which is devoid of connection with the main wall, operates independently as a self-supporting wall. Therefore, it is necessary to fix the facing layer to the laying of the main wall with steel ties. Examination of the facing of the facing layer revealed the presence of damage in the form of cracks having a vertical and horizontal orientation. Based on the results of the survey, recommendations were developed to ensure reliable and safe operation of the building wall structures in close connection with an in-depth analysis of the causes of these damages.
