Known building beam, for example, of rectangular cross section.

In the proposed building beam, in order to simplify the technology for manufacturing the reinforcing cage and increase its strength, each connecting rod of the cage is made with spherical thickenings at the ends, by means of which it is connected to pro, θ longitudinal reinforcement so that its axis is perpendicular to the axis of the longitudinal reinforcement.

In FIG. 1 shows the proposed reinforcement cage; in FIG. 2 - connection of the longitudinal elements of the frame with a transverse connection.

A transverse 2θ bond 2 made in the form of a cylindrical rod with spherical thickenings at the ends is attached to the longitudinal elements 1, made, for example, of squares.

The connection in the form of contact welding is performed by welding pliers 25 pressing the spherical thickening of the transverse links 2 to the inner surface of the longitudinal elements 1.

The mechanized process of manufacturing the reinforcing cage consists in the fact that the transverse connections, which are reinforcing bars with spherical thickenings planted at the ends, are placed in special bins, from where they are manipulated and fed to the place of their welding to the longitudinal elements, which are previously located and fixed in a special stand, determining the shape of the reinforcing cage.

Claims (1)

A construction bar is known, for example, of rectangular section. In the proposed construction bar, in order to simplify the construction of the reinforcement cage and increase its strength, each connecting rod of the framework is made with spherical thickenings at the ends, by means of which it is connected to the longitudinal reinforcement so that its axis is perpendicular to the axis of the longitudinal reinforcement. FIG. 1 shows the proposed reinforcement cage; Fig. 2 shows the connection of the longitudinal elements of the frame by a cross-connection. To the longitudinal elements 1, made, for example, of squares, is welded by a cross link 2, made in the form of a cylindrical rod with spherical thickenings at the ends. Contact welding is made by welding tongs, which press the spherical thickening of the cross links 2 to the inner surface of the longitudinal elements 1. The mechanized process for manufacturing the reinforcement cage is that the cross links, which are rebars with spherical thickenings planted at the ends They are placed in special bunkers, from where the manipulators are fed to the place of welding them to the parental elements, which are preliminarily arranged and fixed in a special manner. th stand, determined yuschem form the reinforcing cage. Claims of construction bar, e.g., rectangular section, characterized in that, in order to simplify the technology of manufacturing the reinforcement cage and increase its strength, each connecting rod of the framework is made with spherical thickenings at the ends, through which it is connected to the longitudinal reinforcement so that the axis is perpendicular to the ori of the longitudinal reinforcement.
