Description

Technical Field

[0001] The invention relates to the technical field of prestressed carbon fiber anchors, and in particular to a detachable prestressed carbon fiber anchor. Background Art

[0002] Prestressed carbon fiber anchors are suitable for anchors used for prestressed concrete tensioning during engineering construction. They are often used in bridge construction. They are pre-installed and positioned, and then poured with concrete. They are buried at both ends of the concrete, that is, the two ends of the corrugated pipe. They are end faces set for the stabilization of the jack during tensioning.

[0003] For example, the public document CN109881591A discloses a carbon fiber plate reverse tensioning prestressed anchor, which includes a tensioning end tensioning assembly and a fixed end fixing assembly fixedly mounted on concrete for clamping the carbon fiber plate, and a tensioning tooling for auxiliary tensioning of the carbon fiber plate; the tensioning end tensioning assembly includes a tensioning end fixing plate fixedly mounted on concrete and a tensioning end clamp for clamping the carbon fiber plate; the fixed end fixing assembly includes a fixed end fixing plate fixedly mounted on concrete and a fixed end clamp for clamping the carbon fiber plate; the tensioning tooling includes a tensioning screw, a tensioning thrust plate and a tensioning top plate; a jack is placed between the tensioning thrust plate and the tensioning top plate to push the tensioning end clamp to realize reverse tensioning of the carbon fiber plate. The present invention not only makes the reinforced concrete member evenly stressed and maintains stress for a long time, but also does not require grooving the concrete surface, which can ensure that the distance between the installed prestressed carbon plate and the concrete surface is minimized and avoids secondary damage to the concrete.

[0004] However, the tensioning tooling structure in the above-mentioned device cannot be effectively disassembled and is not convenient for recycling. In addition, without a torque wrench, it is difficult to ensure that the preload force of each bolt is consistent, which may easily lead to excessive preload force and damage the carbon fiber anchor.

[0023] The metal sheet 615 is magnetically fixed to a plurality of groups of magnetic blocks 617 , and the two groups of indicator bars 619 correspond to the two groups of scale gauges 620 , respectively.

[0024] When installing the positioning components 6 on both sides to several groups of bolts three 610, tighten the nuts on the bolts three 610, and use the universal level 616 to observe whether the positioning frame 69 is installed tilted. The tightening position of the nuts on each group of bolts three 610 is kept consistent to avoid the prestressed carbon fiber plate anchor 5 from generating torque during use, which may cause the prestressed carbon fiber plate anchor 5 to crack or be damaged. At the same time, when tightening several groups of bolts three 610, the positioning frame 69 on the lower side will move closer to the positioning frame 69 on the upper side, squeezing the gasket two 61 1.

After releasing the push plate 78, the opening 711 will push the positioning plate 79 into the bayonet 4, and the tensioning assembly 7 can be installed on the positioning sleeve 2 close to the side of the positioning assembly 6, so as to achieve the purpose of rapid installation and disassembly, and the tensioning assembly 7 can be recycled, and then the jack 74 is started to drive the top block 75 to push the positioning assembly 6 to move, so as to achieve the purpose of tensioning the prestressed carbon fiber plate anchor 5, thereby increasing the rigidity, stability and seismic resistance of the structure.

[0028] Working principle: When in use, first press the push plate 78 extending from one side of the two sets of positioning shells 72, and the tooth groove 710 on the push plate 78 drives the meshing gear bar 77 to rotate, pushing the meshing positioning plate 79 on the upper side to retract into the opening 711, and then align the position of the positioning plate 79 with the bayonet 4 opened on both sides of the positioning sleeve 2. After releasing the push plate 78, the opening 711 will push the positioning plate 79 into the bayonet 4, and the tensioning assembly 7 can be installed on the positioning sleeve 2 near the side of the positioning assembly 6, which can achieve the purpose of rapid installation and disassembly, and the tensioning assembly 7 can be recycled, and then start the jack 74 to drive the top block 75 to push the positioning assembly 6 to move, so as to achieve the prestressed carbon fiber. The purpose of tensioning the plate anchor 5 is to increase the rigidity, stability and earthquake resistance of the structure; in addition, when the positioning components 6 on both sides are installed on several groups of bolts three 610, the nuts on the bolts three 610 are screwed, and the use of the universal level 616 can be used to observe whether the positioning frame 69 is installed tilted. The tightening position of the nuts on each group of bolts three 610 is kept consistent to avoid the prestressed carbon fiber plate anchor 5 from generating torque during use, which may cause the prestressed carbon fiber plate anchor 5 to crack or be damaged. At the same time, when tightening several groups of bolts three 610, the lower positioning frame 69 will move closer to the upper positioning frame 69, squeezing the gasket two 611, and the lower side When the positioning frame 69 is displaced, the front and rear indicator bars 619 are driven to move upward, and the indicator bar 619 indicates the position of the scale 620, which determines the pre-tightening force of the bolt three 610 after fixing the positioning frame 69, so as to avoid the inconvenience of the subsequent positioning component 6 and the bolt three 610 to be disassembled, and the lower side anchor clamp plate 62 drives the indicator bar 619 to move, and cooperates with the indication of the scale 620 to indicate the pre-tightening force of the anchor clamp plate 62 when fixing the prestressed carbon fiber plate anchor 5, so as to prevent the prestressed carbon fiber plate anchor 5 from being damaged after the pre-tightening is too large; finally, the two sets of gaskets one 61 and the anchor clamp plate 62 are clamped on the outside of the prestressed carbon fiber plate anchor 5 by the bolt two 64. When the fixing plate 67 and the two sets of round rods 66 are pushed by the jack 74, the anchor clamp 62 will slide in the two sets of positioning frames 69 to realize the tensioning of the clamped prestressed carbon fiber plate anchor 5. After tensioning to a suitable position, the limit nut 614 is rotated along the threaded rod 612 to make the limit nut 614 fit one end of the vertical plate 65 to limit the tensioned anchor clamp 62 to prevent rebound. At this time, the telescopic rod of the jack 74 can be retracted to disassemble the tensioning assembly 7. There is no need to limit the tensioning assembly 7. Positioning assemblies 6 are installed on both sides of the prestressed carbon fiber plate anchor 5. The purpose of tensioning can be achieved on both sides, thereby improving construction efficiency.
