FILLING ANCHOR FOR BUNDLE FIXATION FROM COMPOSITE REINFORCEMENT Russian patent published in 2019 - IPC E04C5/12 

FIELD: construction.

SUBSTANCE: invention relates to construction, namely to anchors for reinforcement of bundles of composite reinforcement when making pre-stressed, mainly, reinforced concrete structures. In the anchor bolt for fixing the composite reinforcement bundle, including the hollow body, which is filled with the composite compound, housing has the shape of a truncated cone with a diaphragm in a narrow part and using a separator in the developed part of the housing, which fixes the position of composite rods, creating self-hovering effect in the bundle of composite rods. Internal space in the housing is filled with a compound based on butacryl, dried screenings of rock crushing, quartz sands, benzoyl peroxide is used as a curing agent. Granite, granodiorite and basalt are used as rocks. Rocks can be of following fractions: 0.5–1.0 mm, 1.0–2.5 mm.

EFFECT: provision of ideal tight contact with anchoring medium of equal and simultaneous tension of all rods of bundles.
