Steel strand slippage preventing device
The invention relates to a steel strand slippage preventing device, and belongs to the technical field of steel strand prestress anchoring. The device comprises a tensioning anchorage device and an antiskid anchorage device, wherein the tensioning anchorage device includes an anchor plate and a clamping piece, a plurality of anchor holes allowing steel strands to penetrate through are arranged inthe anchor plate, and the steel strands are anchored on the anchor plate through the clamping piece; and the antiskid anchorage device is located on a tail end of the tensioning anchorage device and includes a base plate and a P-type anchorage device, the plurality of anchor holes used for allowing the steel strands to penetrate through are arranged in the base plate, and the steel strands are anchored to the base plate through the P-type anchorage device. According to the device, the tensioning anchorage device and the antiskid anchorage device are used for jointly anchoring the steel strands, an anchoring force of the steel strands is increased, and the steel strands are ensured to have a good antiskid capacity under conditions of a low stress, a wind vibration effect, corrosion of clamping piece screw openings, impact generated by collision of a structure and the like.
本申请涉及一种钢绞线防滑脱装置，属于钢绞线预应力锚固技术领域，包括：张拉锚具，张拉锚具包括锚板和夹片，锚板上开有多个用于穿过钢绞线的锚孔，钢绞线通过夹片被锚固在锚板上；防滑锚具，防滑锚具位于张拉锚具的尾端，防滑锚具包括垫板和P型锚具，垫板上开设有多个用于穿过钢绞线的锚孔，钢绞线通过P型锚具被锚固在垫板上。本装置利用张拉锚具和防滑锚具共同对钢绞线锚固，增加了钢绞线的锚固力，确保钢绞线在低应力、风振作用、夹片丝口锈蚀、结构物撞击产生冲击等情况下具有良好的防滑能力。
