The invention relates to the construction, in particular to the construction of columns of industrial buildings and structures, as well as the main buildings of power plants.

The aim of the invention is to improve the manufacturability and fabrication and increase rigidity.

Figure 1 presents the armo-block of the column, a longitudinal section; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1.

The armoblock of the column includes longitudinal bars 1 of the outer reinforcement, for example, from an angular profile, to which transverse rigid closed frames 2 are welded, for example, from an angular profile, located along the column with a regular pitch. The sides of the corners 2 from the corners are distant from the outer surface of the column by the distance required for placing the profiled sheet 3 flush with the edges of the column. The profiled sheet 3 can be fastened to the transverse frames and corners of the external reinforcement, for example, with electric rivets or self-tapping bolts 4. To eliminate the possibility of the transverse rods buckling during the process of concreting, they are fastened by straps 5.

If necessary, additional reinforcement 6 of a round profile is inserted into the reinforcement block of the column in the form of grids or frames. The reinforcing mesh can also be installed between the profiled sheet and the transverse frames with the location of the longitudinal round reinforcing bars 6 in the area of the protrusions of the corrugation.

Metal frameworks of columns are mounted from separate reinforcing blocks with the organization of joining using welding or on high-strength bolts. After unfastening, they are concreted by pouring concrete into the columns. In this case, the profiled sheet serves as a permanent formwork and, together with the sealing putty, ensures the tightness of the reinforcement

block during concreting. The profiled sheet serves to increase the bending stiffness of the columns in the assembly state and bears the function of the structural reinforcement of the concrete section. The load from newly laid concrete is transmitted through the profiled sheets to the transverse closed diaphragm frames and is perceived by them.
