Abstract

For the construction of residential facilities, even today, they often use a frame-monolithic scheme with floor filling with enclosing structures made of artificial materials - brick, foam concrete, etc. For objects built 25-30 years ago, today there is a whole complex of common problems associated with the destruction front (front) layer of masonry. For this, domestic and foreign developments in the field of inspection and reinforcement of bearing and self-supporting brick structures are analyzed. Among the main criteria for destruction, factors of natural and anthropogenic origin are determined. Climatic conditions - ambient temperature, humidity - significantly affect the choice of basic material, and the current requirements for energy efficiency of building structures significantly affect design decisions for the use of various heaters. At the same time, all architectural and constructive solutions built on modern energy-saving technologies in compliance with current regulations are ineffective in poor quality work. And the desire of the developer to reduce the cost of square meters of housing due to savings on high-quality materials and their required volumes leads over time to emergency situations. In the case of brickwork, most often there are interfloor destruction and loss of elements of the outer surface due to the incorrect (insufficient) number of bonds between the planes. The traditional methods of performing work with reinforcing and restoring masonry are analyzed.The article discusses options for reinforcing multilayer brickwork, which can be applied locally. Formwork fastening elements can be used as reinforcing elements and anchor systems for further reinforcement or finishing. The basic recovery scheme is based on the concept of minimizing costs with a high level of technological processes
