FIELD: construction engineering. SUBSTANCE: zones of fixing one vault-shell on another vault-shell are divided by sealing rings and filled with hardening material. For adaptation of load-bearing anchor to corresponding object, plastic member is slipped over load-bearing anchor. Plastic member is provided with several sealing rings which are fixed at distance from each other by means of spacers and/or collars. Plastic member also has covering washer with injector hole. Covering washer in its edge zone has holes, which are connected with fixing zones independently from each other. Filling of fixing zones which are separated from each other is carried out individually and by different processes. Aforesaid embodiment of load-bearing anchor is convenient in assembling and economic in installing. It can be used in different conditions in wide range of applications. EFFECT: higher efficiency. 4 cl, 6 dwg
