Multi-layer aerated concrete block with improved thermal protection properties

摘要

A utility model refers to multi-layer building blocks. The technical result is the creation of a homogeneous wall block, which is made of layers of aerated concrete of different density and coefficients of thermal conductivity with improved heat-shielding and deformative qualities. The technical result is achieved by the fact that a multifunctional aerated concrete block with improved heat-shielding qualities, including interconnected layers of aerated concrete, are connected to each other in a single block by the groove-groove principle, which provides a large contact area for bonding the layers, each of the layers differs in density and thermal conductivity coefficient , and the number of layers in the block is determined by the required design strength and thermophysical characteristics for wall loads and climatic characteristics stikam district construction, the layers are arranged in relation to each other in such a way that the density values ​​and the coefficient of thermal conductivity decrease in the direction from the inner layer (maximally dense) to the outer layer (with the lowest density), while ensuring a normal process of heat and mass transfer and the required calculated strength and heat transfer resistance, utility model slots and ridges have a rectangular shape, the outer layers of the aerated concrete block in cross-section are made of a channel-shaped shape, and the inner interlocking layers with n hence alternating between a and dvutavroobraznyh cruciform cross-sectional shapes.
