Geleta A. Technology of Adhesive Fixing the Metal Anchors with the Non-round Section in Concrete

The technical and economic expediency of the method of fixing the metal anchors with the non-round section (plates, corners, channel etc.) into the prefabricated concrete structures by means of glueing was grounded and the technological parameters of the fixing process were determined. The technological peculiarities of forming bore-holes with the rectangular section (boring the cylindrical bore-holes with the following removing the bulkheads between them) have been investigated taking into account the dimensions and configuration of the anchor's elements sealed into the concrete. Use of the epoxy compositions with high filling having high strength and viscosity that allows installing the anchors in the horizontal bore-holes was grounded. The dependences of the velocity and duration of boring on a concrete class and the bore-holes' diameters for the different values of depth as well as the ones of duration of removing the bulkheads on their thickness were determined. The experimental research of the bearing ability of the glue anchors with the rectangular section has been held and as a result their high strength under the shear load, which is typical for the imbedded items, has been confirmed.
