METHOD TO REINFORCE PRECAST PANELS OF SURFACE FROM CELLULAR CONCRETE Russian patent published in 2015 - IPC E04G23/02 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, in particular, to the method to reinforce precast panels of cellular concrete surface. The method of reinforcement consists in the fact that the roof structure is opened along the seam of coupling of adjacent panels for the width of 300-400 mm. Then they cut through slots with width of 85-90 mm along the seams through the entire length of the panel, afterwards they insert longitudinal steel beams into the slots from the top, having gussets at the bottom to fix cross beams. Cross beams are connected to longitudinal beams and are connected by gussets with longitudinal beams by assembling bolts. Gaps between cross beams and the reinforced panel are filled with concrete, and gaps between longitudinal beams and side surfaces of panels are filled with construction foam. The slot above the surface of longitudinal beams is filled with a heat insulation material, then the roof design is restored, and steel reinforcing elements protruding beyond the ceiling surface are coated by protective materials.

EFFECT: increased bearing capacity of a coating panel.
