FIELD: construction.
SUBSTANCE: invention is related to isolating curb reversible in horizontal direction and intended for manufacture of concrete structures. Isolating curb includes the following components: the first and the second panels substantially installed one opposite to the other, every of which has top surface, bottom surface, the first end surface, the second end surface, external surface, determining wall and internal surface for concrete perception, at that the first end surface and the second end surface of the first panel have both tenons and grooves arranged so that in the first end surface of the first panel tenon is located closer to external surface, and groove is arranged closer to internal surface, in the second end surface of the first panel groove is installed closer to external surface, and tenon is arranged closer to internal surface, in the first end surface of the second panel groove is located closer to external surface, and tenon is located closer to internal surface, in the second end surface of the second panel tenon is located closer to external surface, and groove is closer to internal surface, at that panels are located so that the first end surface of the first panel is located opposite to the first end surface of the second panel, and second end surface of the first panel is located opposite the second end surface of the second panel. And also at least two strainers that connect the first and the second panels between each other, in which two or more curbs may be installed in horizontal direction and connected between each other for provision of flat plane with the help of connection created both by tenon and groove of every panel of one curb, which are connected with tenon and groove of every panel of the other curb, at that these curbs have the possibility to be connected conversely to any of two sides so that the first end surface of the first and second panels of one curb may be connected both to the first and second end surfaces, as well as to the second end surface of the first and second panels of the other curb. At that every strainer includes at least three parallel horizontal wires that are installed in the same plane at such distances from each other so that total distance from the lowest horizontal wire to the highest horizontal wire is less than height of two panels installed one opposite to the other, and length of every wire is more than the distance between external surfaces of these two panels installed one opposite to the other, at that at equal distance from every end of each horizontal wire there is bend provided at the right angle, which is arranged so that every bend at the right angle is located between external and internal surfaces of panel; at least three parallel vertical wires, which are located in one plane at such distances from each other, which are less than distance between bends at the right angle from every of the ends of horizontal wires, and length of every wire is at least equal to the total distance from the lowest horizontal wire to the highest horizontal wire; at least three horizontal wires and at least three vertical wires are located so that every horizontal wire contacts and crosses at the right angle all vertical wires, and every vertical wire contacts and crosses at the right angle all horizontal wires, at that these wires are welded to each other in every point of crossing; and also metal plate installed on internal side of bend at the right angle from every of the ends of horizontal wires, at that at least part of metal plate is basically parallel to external surface of panel, inside of which such bend is arranged at the right angle, and every metal plate contacts every horizontal wire and is welded to it. Also variant of isolating curb is described.
EFFECT: creation of isolating curb with welded wire strainer, which contains at least three horizontal wires and three vertical wires, simplification of curb design, provision of higher strength of structure installed between panels located one opposite to the other.
