METHOD OF REINFORCEMENT OF WALLS FROM BRICK MASONRY AND INJECTION DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC E04G23/02 

FIELD: construction.

SUBSTANCE: invention relates to construction, specifically to reinforcement of masonry. First, a well with diameter larger than an anchor outer diameter is drilled in the masonry with cracks. Then, after cleaning and blowing of the well, it is closed from the outside with a detachable washer attached to the masonry so that the center of the central hole of the washer coincides with the well axis. An injector is introduced into the central opening and a polymer-cement composition is injected into the well through the through holes of the injector tip, while slowly injecting the injector from the well. When the well is filled with a polymer-cement composition, air is forced out from the well through a hole of smaller diameter in the upper part of the washer above the central hole. When the fragments of the polymer-cement composition appear from the hole of smaller diameter, the composition is stopped and the injector is removed from the well. After that, anchor in form of corrugated reinforcement is introduced into the well through the central hole of the washer. After solidification of polymer-cement composition washer is detached from masonry and wall surface is puttied.

EFFECT: technical result is increase in the operating reliability of the masonry.
