SU1264A1 - Shaped concrete stone - Google Patents

Description

The proposed shaped concrete stone in the form of direct zeta is intended to ensure an absolutely flawless interconnection of the outer, middle and inner row, without the use of iron or other auxiliary parts.

FIG. 1 is a perspective view of shaped stone; FIG. 2 is a top view of the piling with one internal row of shaped stones; and FIG. 3 is a top view of the laying with two internal rows of shaped stones.

The advantages of a ready-made wall of manually-molded stones of the molding series can be used in countries with harsh winters like Russia only if the wall structure which must necessarily have two hollow layers ensures that the outer, middle and inner p are absolutely perfect. yes without the use of iron installations, etc .; Do not make it impossible to manufacture stones in a simple and fast manual way.

Establishing interconnection between the inner, middle and outer row

It is possible with the help of a two-angled concrete stone (in the form of a direct zeta), one short face of which comes on the outer, friend on the inner layer, serving as a strong joint of the wall (Fig. 1 and 2). In the place where the middle longitudinal row intersects with the transversal knees in the main section, the longitudinal row should form an angle of 45 with the nearest stone so that the transverse joints lie straight and without gaps. Only in this way will it be possible for the lateral faces of medium-sized double-sided stones to cross onto the lateral faces of the adjacent high and lower internal and external stones. The difficulty of fulfilling the second requirement — the constructions by molding rows is eliminated by the fact that both inner faces of two-sided stones are inclined to each other at an angle of 45 ° -the same length with two outer edges.

Where the temperature is kept quite low for a long time, for example, below 25-30 Reaumur, it is necessary to turn on the third insulating air layer, which is achieved by introducing a second

p yes double-angled stones (fig. 3). When filling two inner layers with slag and so on, this air layer corresponds in thermal terms to a massive wall with a thickness of at least three bricks (75 s.) Made of baked bricks or a wall 2/2 thick with an insulating air layer (70 --75 centimeters).

SUBJECT OF PATENT

Shaped concrete stone in the form of direct zeta, intended for internal rows when laying walls of angular stones, characterized in that the right angles formed by the shelves of stones with its wall are blunt at angles of 45. K1264
