Abstract

1. CONSTRUCTION STONE with heat insulating longitudinal layers separated by concrete bridges, so that, in order to increase heat resistance and heat resistance of external walls, each subsequent heat insulating layer on both sides of the middle layer has thermal inertia, increased by the amount of thermal inertia of the average heat insulating layer, and the heat inertia of concrete Leremychek is inversely related when the ratio of thermal conductivity of heat insulating layers is eve and stone material within. 2. A building stone according to claim 1, characterized in that the plane is horizontal on the side of the voids filled with insulation,. equipped with a plate of filler material, made in the process of 07 filling voids with a width less than the width of the stone by an amount corresponding to the value of the mortar seam along the longitudinal edges of the stone.

The invention relates to construction and is intended for low-rise construction, mainly in rural areas, in climatic regions with sharp fluctuations in external temperatures, for example, in the conditions of Central Asia.

The purpose of the invention is to increase the heat resistance and heat transfer resistance of external walls.

FIG. I depicts a building stone; view from above; in fig. 2 shows section A-A in FIG. 1, without insertion; in fig. 3 - the same, with an insert of heat insulating material; in fig. 4 insert, axonometrics; in fig. 5 is a section BB in FIG. one.

Building stone 1 contains concrete lintels 2, a section of its space into compartments 3 and grooves 4.

The width of the compartments 3 is such that when they are filled with insulation, the ratio of thermal inertia of the heat insulating layers in a ratio of 1: 2: 2 is reached, and jumpers 2 are made wide, providing a relationship with the thermal inertia of bridges in the ratio 3: 2: 1 to the outer walls. In the lower part of the stone 1, the outermost layers 5 have projections 6. The compartments 3 of the stone 1 are filled with an insert 7 of rigid effective insulation, for example lightweight concrete, foam concrete, wood concrete, polystyrene foam, etc. The insert 7 is made in the form of a plate 8 with a width less than the width of the stone 1 by an amount sufficient

for arranging the mortar joint along the longitudinal edges of the stone during the process of pressing the outer walls and protruding elements 9 from them in shape.

corresponding compartments 3, with grooves 10 for the mortar seam being made along the edges of the plate 8.

When the upper stone is installed on the lower (B of the wall masonry process) plate 8 is dry laid on the upper side of the lower stone. The joining of the stone stones is carried out with a solution previously laid in the grooves 4 along the lower stone and pressing it with the grooves 10 of the upper stone. Dp creating a more dense mortar connection after laying the stones is made jointing. The laying of the outer walls of stones is carried out in one row with the dressing of vertical joints.

The results of the study of heat resistance and thermal resistance of building stones are given in

5 tab. I and 2.

Making construction stones is carried out on presses SMT-188 and SMT-225. Structural concrete and pointers are poured into the existing mold

Q sleep create compartments of appropriate sizes. Then heat insulating material with a low thermal conductivity coefficient is poured into the compartments in liquid form.

Along the longitudinal edges of the stone grooves and the plates on the upper part of the stone, a rectangular frame is installed.
