Possibility of using super-thin liquid thermal insulation for protection of steel beams embedded in brick wall exterior under building reconstruction

Abstract

The article presents the results of calculations on changing the thermophysical properties of the connectivity node of the outer wall and the balcony plate resting on the cantilever fixed steel beams. A variant of insulation of steel beams with super-thin liquid insulation under the reconstruction of existing brick buildings with single-layer brick walls is proposed. The graphical analysis of the problem was carried out. The results of calculations of temperature with linear thermophysical properties show that the method of steel beams insulation within the conditions of reconstruction of residential buildings makes it possible to increase the building life. When using super-thin thermal insulation coatings, it is possible to reduce the local freezing of the balcony plate.
