INSTALLATION OF PREFABRICATED CONCRETE AND CONCRETE STRUCTURES 5. Installation of wall panels

Installation of panels of external and internal walls should be made, leaning them on beacons adjusted to the mounting horizon. The strength of the material from which the beacons are made should not be higher than the compressive strength of the mortar used for the bedding device as specified by the project.
Deviations of beacon marks relative to the mounting horizon should not exceed ± 5 mm. In the absence of special instructions in the draft, the thickness of the beacons should be 10-30 mm. There should be no gaps between the end of the panel after its alignment and the mortar bed.
The alignment of the panels of external walls of single-row cutting should be done:
- in the plane of the wall - by combining the axial risk of the panel at the bottom level with the reference risk on the overlap from the center axis. If there are zones of accumulated errors in the joints of panels (when joining panels with overlapping in places where loggias, bay windows and other projecting or falling parts of the building are aligned), alignment can be made using templates that fix the design size of the seam between panels;
- from the plane of the wall - combining the bottom edge of the panel with the installation risks on the floor, rendered from the center axes;
-in the vertical plane - adjusting the inner edge of the panel relative to the vertical.
The installation of the waist panels of the exterior walls of frame buildings should be carried out:
- in the plane of the wall - symmetrically with respect to the axis of the span between the columns by equalizing the distances between the ends of the panel and the risks of the axes of the columns in the level of installation of the panel;
- from the plane of the wall: at the bottom of the panel - combining the lower inner edge of the panel to be installed with the edge of the lower panel; at the top level of the panel - combining (using a template) the face of the panel with the risky axis or the face of the column;
The alignment of the wall panels of the exterior walls of frame buildings should be performed:
- in the plane of the wall - combining the risk of the axis of the bottom of the panel to be installed with the reference mark on the waist panel;
- from the plane of the wall - combining the inner edge of the panel to be installed with the edge of the lower panel;
-in the vertical plane - adjusting the inner and end faces of the panel relative to the vertical.
