Abstract
The utility model relates to a pre-tightening device, in particular to a strand tapered anchorage pre-tightening device, which comprises a first supporting steel plate (3) and a second supporting steel plate (4) which are fixedly arranged at the two ends of threaded screws (1) by two parallel threaded screws (1) and through nuts (2) respectively, wherein the two parallel threaded screws (1), the first supporting steel plate (3) and the second supporting steel plate (4) form a rectangular frame; and an anchoring component is arranged in the rectangular frame. Thus, the pre-tightening device has the advantages of rational design, simple structure, complete practicability, capability of avoiding a slide phenomenon occurring in a tensioning process due to insufficient pre-tightening of a carbon fiber bar, no need of special table, easiness and convenience in operation, high economy and reliability in pre-tightening force.
Description
Technical field
The utility model relates to a kind of pre-tightening apparatus, especially relates to a kind of strand tapered anchorage pre-tightening apparatus.
Background technology
Carbon fibre bar radially tensile strength is high, but its horizontal flexural capacity is lower, and existing prestress wire firmly beforehand means because the intermediate plate follow-up is asynchronous, very easily clamps the position and produces excessive shear stress and cause partial cut damaged in presstressed reinforcing steel material end.Therefore, the prestress wire firmly beforehand means can't directly apply to shearing resistance and the lower pre-stressed carbon fiber muscle of compressive strength.
The utility model content
The utility model mainly is to solve the existing prestress wire firmly beforehand means of existing in prior technology, because the intermediate plate follow-up is asynchronous, clamps in presstressed reinforcing steel material end very easily that the position produces excessive shear stress and the technical problem that causes partial cut breakage etc.; Provide a kind of carbon fibre bar pretension of avoiding sliding phenomenon in stretching process, to occur inadequately, need not special pedestal, easy and simple to handle, good economy performance, the reliable a kind of strand tapered anchorage pre-tightening apparatus of pretightning force.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of strand tapered anchorage pre-tightening apparatus; It is characterized in that; Comprise first supporting steel plate and second supporting steel plate that are separately fixed at silk mouthful screw rod two ends by two silk mouthful screw rods that laterally arrange and through nut; Said two silk mouth screw rods, first supporting steel plate and second supporting steel plate constitute a rectangular frame, are provided with anchoring assembly in the said rectangular frame.
At above-mentioned a kind of strand tapered anchorage pre-tightening apparatus; Said anchoring assembly comprises one one end and the fixing jack of first supporting steel plate; The said jack other end is provided with the strand tapered anchorage that is used for the stretch-draw carbon fibre bar, and said strand tapered anchorage is arranged on said second supporting steel plate.
At above-mentioned a kind of strand tapered anchorage pre-tightening apparatus, said second supporting steel plate is provided with a U type groove, and said U type bottom land end center overlaps with the second supporting steel plate center.
At above-mentioned a kind of strand tapered anchorage pre-tightening apparatus; The center connecting line of said first supporting steel plate and second supporting steel plate is parallel with silk mouthful screw rod, and above-mentioned jack and strand tapered anchorage central axis overlap with the center connecting line of first supporting steel plate and second supporting steel plate.
At above-mentioned a kind of strand tapered anchorage pre-tightening apparatus, also be provided with a power transmission steel plate between the said jack other end and the strand tapered anchorage.
Therefore, the utlity model has following advantage: 1. reasonable in design, simple in structure and complete practicality; 2. avoid the carbon fibre bar pretension sliding phenomenon in stretching process, to occur inadequately, need not special pedestal, easy and simple to handle, good economy performance, pretightning force is reliable.
