The application discloses a composite cable connecting assembly, a strain-type fitting and a mounting method, and belongs to the technical field of composite material products. The composite cable connecting assembly comprises a composite cable core, the composite cable core comprises a composite core rod and aluminum strands covering the composite core rod, a part of the composite core rod is exposed outside the aluminum strands, and the composite cable connecting assembly further comprises at least one tapered portion fixed to the composite core rod exposed outside the aluminum strands, wherein the tapered portion is integrally wrapped and solidified by the same material as the composite core rod, and an accessory is fixed to the composite core rod through fastening cooperation with an outer tapered surface of the tapered portion. The composite cable connecting assembly, the strain-type fitting and the mounting method have better fatigue resistance, high connection stability, light overall weight and the advantage of convenient construction.

The utility model relates to a clamping type anchorage device suitable for CFRP stranded wires or rib materials, and belongs to the technical field of bridge engineering, and the clamping type anchorage device comprises a steel sleeve, a clamping piece, an aluminum sleeve and a bolt. Wherein the steel sleeve is an inner conical cylinder with an invariable outer diameter and a reduced inner diameter; one end of each clamping piece is separated, and the other end of each clamping piece is complete; one end of the aluminum sleeve is separated, and the other end of the aluminum sleeve is complete; the bolt is in threaded connection with the outer side of the steel sleeve. The inner surface of the steel sleeve, the clamping pieces and the inner and outer surfaces of the aluminum sleeve are specially treated. Compared with a common clamping type anchorage device, the anchorage device has the advantages that the pressure stress on the surface of the CFRP stranded wire or rib material is reduced, the friction force between the stranded wire or rib material and the aluminum sleeve is increased, and larger drawing force is provided; the anchorage device is convenient to install and can be used for cables or prestressed structures.

The application relates to the technical field of structural reinforcement engineering, and discloses a carbon fiber plate anchorage device, which comprises an upper cover plate and a lower cover plate, the upper cover plate and the lower cover plate are oppositely arranged, the inner walls of the two are respectively provided with inclined guide surfaces which are gradually narrowed from the middle section to the tail end, and the two sides of the upper cover plate and the lower cover plate are respectively provided with inclined guide rails which protrude outward; at least three pairs of wedge blocks, each pair of wedge blocks comprises two wedge blocks which are symmetrically arranged in the inner cavity between the upper cover plate and the lower cover plate, and the outer side inclined surface of each wedge block is inclinedly attached to the inclined guide surface of the inner wall of the corresponding cover plate. The gradually changing rigidity design of the transition assembly makes the cross-section rigidity of the carbon fiber plate at the anchoring end gradually change from the free section to the anchoring end, the cross-section rigidity mutation is eliminated, the concentrated shear peak at the anchoring section is converted into the uniformly distributed shear along the length direction of the transition assembly, the interlaminar peeling damage of the carbon fiber plate at the anchoring end is effectively prevented, and the long-term reliability of the anchoring system is remarkably improved.

The utility model relates to a temperature control device for bridge cable hot casting anchor anchoring material casting, relates to the device of hot casting anchor anchoring material casting, including at least one installation dynamic heat preservation device on the anchor cup, dynamic heat preservation device includes annular sleeve, heat preservation device, temperature sensor, control system, the inner hole of annular sleeve is covered on the outer surface of anchor cup, heat preservation device, temperature sensor are installed in the closed cavity of annular sleeve respectively, the signal output end of temperature sensor is connected with the signal input end of control system, the signal output end of control system is connected with heat preservation device, the utility model discloses through heat preservation device can make the anchoring material in the anchor cup keep proper temperature, solve the problem of the insufficient compactness caused by the big void ratio of anchoring material and the uneven casting, further promote the anchoring efficiency, can also reduce the thermal stress crack in the cooling process of casting, significantly improve the anchoring material quality.
