FIELD: construction.
SUBSTANCE: installation method of anchoring involves preparation of a hole in base porous material, installation into prepared hole of hollow of holding device with discharge openings, feeding construction binder solution and introduction into hollow holder, filled with mortar, anchor bar. Feeding mortar into hollow retaining device is under excessive pressure, under which a binding solution is held before installation of anchor bar, hollow retaining device is made in form of dowels, head is equipped with slots, and body-projections on its entire outer surface in form of a spiral, geometric dimensions of which on opposite ends of body of dowel is larger than that in its middle part, longitudinal outlets are located in middle part of body dowel diameter of external surface of which is less than on opposite ends of body of dowel.
EFFECT: invention can be used during installation of hinged structures in base of porous materials and aims at increasing area of contact construction binder solution with porous base material.
