Сonstruction of Facades of Brick Buildings from Prefabricated Insulated Brick Panels (Piers) of Factory Manufacture

The high labor intensity of constructing  insulated brick walls has led to a significant reduction in brick consumption in the Republic of Belarus. Considering that in each region there is at least one brick factory equipped with modern technological equipment, and the reserves of mineral raw materials (sand, clay) for making bricks are practically inexhaustible, the development of an effective structural and technological solution for insulated brickwork is an urgent task. As practice shows, today the majority of brick buildings being erected are low–rise (3-5 floors) – these are secondary schools, kindergartens, clinics, buildings for household purposes (laundries, dry cleaners, etc.), as well as administrative buildings. The floor layout of the premises of these buildings is, as a rule, cabinet (the number of window openings is significant). In this regard, it is proposed to use factory-made insulated brick panels (piers) to reduce the labor intensity of constructing the facades of such buildings. A distinctive feature of the proposed solution for insulated brickwork from those commonly used is that, to increase operational efficiency, it is made of two separate structural elements: load-bearing and heat-insulating and decorative. The paper describes in detail the organization and technology of work on the production of the main structural elements of brick insulated facade panels (piers) in factory conditions. The proposed design solution for the facade of brick buildings with a cabinet layout allows the manual technological process of constructing such buildings to be converted into a mechanized one – installation of factory-made insulated brick panels (piers), which will significantly reduce the labor intensity of constructing insulated brick walls. The division of buildings under construction into tiers, the height of which is linked to the range of technological operations and the building materials used, makes it possible to exclude from the work the use of lifting equipment (scaffolding), as well as the delivery of pallets with bricks and mortar boxes to the bricklayer's workplace.
