Using brands to control the vertical of buildings
In the shaft part of the head of the brand, the brand is attached to wooden gestures that support the working floor of the formwork, or on the brackets welded to the circles of the formwork. Peripheral brands roll to wooden gestures supporting the floor of the visor, or directly to the floor.
To ensure visibility under the brand in the suspended forests and in the visors of the formwork, open openings equal to the area of the brand. Each time after the end of observation, the openings should be closed.
To simplify the subsequent processing of observations of the brand, it is necessary to place so that the scales are parallel to the axes of the barrel, an increase in digitization on the corresponding scales was the opposite of the increase in the coordinate X and the axles of the barrel and that the center of the brand and the installation point of the anti-aircraft industry are located approximately on the general vertical.
