RECONSTRUCTION OF MULTI-STOREY INDUSTRIAL BUILDINGS FOR AFFORDABLE HOUSING WITH THE USE OF RESOURCE-SAVING CONSTRUCTION SOLUTIONS

English abstract

In the second half of the last century, the use of reinforced concrete structures was quite common in construction in Ukraine, especially for industrial buildings. However, today, due to a decrease in production, the operation of some industrial buildings is stopped. The article presents the characteristics of an unused industrial building, which affect the architectural-structural and organizationaltechnological solutions during its reconstruction with a change of functional purpose. The plan of a typical half-floor of the replanned industrial building where general dimensions of the apartment fit into an existing grid of columns is shown. Resource-saving constructive solutions for the installation of built-in steel-concrete composite overlap to divide the height of the existing production floor into two identical in heights and layout of residential floors are proposed. To increase the resource conservation of built-in overlaps, the following measures are proposed: the effective sequence of concreting the slab through the span in two stages with a continuous scheme of operation of steel beams; effective installation of struts after the device of a monolithic plate of overlapping; installation of temporary racks under steel beams of a reinforced concrete floor for the time of concreting of a plate and a set of concrete of a plate of design durability. The proposed resource-saving measures for the installation of built-in steel-concrete composite overlaps allow you to use the own weight of the monolithic concrete slab to create pre-stresses in the floor elements, as well as provide the perception of all combined crosssection of the external load at the stage of its installation. The main types of foundations encountered in the reconstruction of industrial buildings with prefabricated reinforced concrete frames are generalized. Given the fact that the technological processes of strengthening existing or laying new foundations must be performed in a limited space and using technologies with minimal movement of resources, the optimal technology is the production of soil-cement by deep soil mixing without excavation. Possibilities of arrangement of effective soil-cement bases and foundations are considered. For different configurations of the existing single shallow foundation, it is possible to use the optimal options for reinforcement with soil-cement columns. Decisions on the installation of new foundations on reinforced soil-cement piles in the middle of the building are given. The constructive and technological advantages of using this technology are presented.
