Abstract
This article is an example of the calculation of a foundation monolithic slab using void formers during the construction of an apartment complex consisting of three buildings located on one stylobation. In this example, we consider several options for calculating multi-hollow foundation slabs in order to determine the most cost-effective design. At the same time, a multi-hollow foundation slab should have the same rigidity and load-bearing capacity as usual.
Highlights
The first mentions concerning the use of void formers in the construction of floors, appeared at the beginning of the twentieth century, around 1905
At the same time, such an overlap reduces the mass by 20-40% than a solid plate, and has greater rigidity and carrying capacity. This is due to the fact that a large part of the concrete of the middle zone is withdrawn from the monolithic slab and is replaced by hollow liners. [2]
In comparison with the beam or captive solution of floor slabs, the construction height of the ceiling is reduced, which during the operation of the building reduces the cost of heating, ventilation and air conditioning
Summary
The first mentions concerning the use of void formers in the construction of floors, appeared at the beginning of the twentieth century, around 1905. [1] At present, both in our country and abroad, builders have begun to show interest in the construction of hollow core slabs with hollow cores. In some European countries, innovative formwork with void formers has already been successfully implemented and used for the construction of lightweight floor slabs. One of such systems for the development and application of formwork are Cobiax (Switzerland) void-forming balls or ellipsoids; Nautilus (Spain) - prismatic empty elements. At the same time, such an overlap reduces the mass by 20-40% than a solid plate, and has greater rigidity and carrying capacity This is due to the fact that a large part of the concrete of the middle zone is withdrawn from the monolithic slab and is replaced by hollow liners. The aim of the work was to compare the results of the calculation of a monolithic stylobation plate with a thickness of 1 m and the foundation with the use of void formers
