FIELD: construction.SUBSTANCE: invention relates to the field of construction, is a fastening agent and may be used in assembly and installation of heavy elements or elements exposed to high load for their fixation relative to vertical or horizontal, preferably concrete, supports, such as walls, ceiling slabs or floor, also for installation of fences on objects of urban and suburban infrastructure. A composite anchor is made from composite material based on epoxide or polyester resin reinforced with glass fibre and glass fabric. It comprises a load-bearing rod 1 and a fixing unit 2. In the load-bearing rod 1 there is an axial through channel 3. On the load-bearing rod 1 there are shaped protrusions 4. The fixing unit 2 comprises a head 5 of the anchor and a fixing nut 6. The head 5 of the anchor is made on the load-bearing rod as a whole with it and has a common through channel 3 with the rod 1. The fixing nut 6 is installed on the rod 1 so that the head 5 of the anchor is placed in the inner cavity 7, made in the fixing nut 6. The support wall of the head 5 is equipped with external thrust lugs 8, which correspond in shape to the inner thrust lugs 9 of the support wall of the inner cavity 7 of the fixing nut 6. To provide for the possibility to let through a double-component quick-hardening glue based on epoxide resin and its placement between the head 5 of the anchor and walls of the inner cavity 7 of the fixing nut 6, the end surface and the support wall of the head 5 are equipped with radially arranged grooves 10, which communicate in pairs by means of longitudinal grooves 11, made on the side surface of the head 5 of the anchor, and the end surface of the anchor head 5 is cone-shaped.EFFECT: invention provides for reliable fixation due to increased stiffness of a structure achieved by solidity of a fixing assembly with a device as a whole.5 cl, 3 dwg |
