Embodiment 1

[0029] Such as figure 1 , figure 2 As shown, a kind of anti-slip device provided by the present invention is used to cover on the steel strand 300 with epoxy resin outer layer 200 near one end of the fixed column 100; comprising: force component sleeve 1; the proximity of the force component sleeve There is a contact base 2 at one end of the fixed column; the contact base is fixed on the fixed column by a fastener 3 . There are a plurality of reinforcing ribs 4 on one side of the contact base, and the width of the reinforcing ribs converges from one end adjacent to the fixing column to the other end.

[0030] The inner diameter of the force component sleeve converges from one end close to the fixed column to the other end away from the fixed column, forming an inclined inner tapered surface 5 . The inner wall of the force component sleeve is provided with multiple sets of ring gears; the ring gears include a first gear 6, a second gear 7 and a third gear 8, the first gear, ...

Embodiment 2

[0035] An anti-skid device provided by the present invention is used to cover a steel strand with an outer layer of epoxy resin near one end of a fixed column; comprising: a force component sleeve; the inner wall of the force component sleeve is provided with multiple groups of ring gears ; The ring gear has inner hard teeth and outer soft teeth covering the outer surface of the inner hard teeth, the hardness of the inner hard teeth is less than the hardness of the steel strand, and the hardness of the outer soft teeth is less than the inner hard teeth hardness; on the axial section, the inner hard tooth is a convex peak with a rounded curve, and the outer side of the outer soft tooth has a pair of protruding heads bifurcated to both ends; when installed, the protruding After the head squeezes into the epoxy resin layer of the steel strand, it touches the steel strand and bends and deforms to form an anti-skid layer.

Abstract

The invention provides an anti-slip device. The anti-slip device is used for externally sleeving a steel strand, close to one end of a fixing column, with an epoxy resin outer surface layer. The anti-slip device comprises a force distribution sleeve; the inner side wall of the force distribution sleeve is provided with a plurality of annular gears, the annular gears are provided with inner hard teeth and outer soft teeth covering outer surfaces of the inner hard teeth, hardness of the inner hard teeth is smaller than that of the steel strand, and hardness of the outer soft teeth is smaller than that of the inner hard teeth; on an axial section, the inner hard teeth are outwardly-extruded convex peaks with smooth curves, and the outer side of each outer soft tooth is provided with a pair ofconvex heads forked towards to ends; in mounting, the convex heads are extruded into the epoxy resin of the steel strand and contact with the steel strand to form an anti-slip layer through bending and deformation. By arrangement of the inner hard teeth and the outer soft teeth with the convex heads, clenching force of the steel strand with the epoxy resin layer is greatly increased, and weak tensile resistance caused by proneness to relative slipping between the anti-slip device and the steel strand is avoided.

Description

technical field [0001] The invention relates to the field of steel strand fastening equipment, in particular to an anti-slip device. Background technique [0002] When the existing steel strands are used, the tensile force on one end is usually smaller than that on the other end. In order to balance the force on the steel strands, it is necessary to add a force component device fixed on the fixed column; the existing steel strands use a The fixed anchor lacks a device for component fastening in the middle of the steel strand, and cannot bite the steel strand with an epoxy resin layer, and it is easy to generate relative sliding between it and the steel strand, resulting in weak tensile capacity . [0003] The existing patent document with the application number CN201721322043.7 discloses the patent document "A Prestressed Steel Strand Connection Device". The force device cannot bite the steel strand with epoxy resin layer, and it is easy to generate relative sliding betwee...
