Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a clip-type anchor for carbon fiber reinforced composite material plates. Background Technology

[0002] The clip-type anchor for carbon fiber reinforced composite (CFRP) plates is a high-precision mechanical device used in prestressed engineering. Through the synergistic self-locking mechanism of the internal conical sleeve and clips, it gently and evenly transfers the huge tensile force to the brittle CFRP plate and permanently locks it. It is a key core component for connecting CFRP materials to concrete or steel structures and achieving efficient reinforcement, solving the anchoring problem of high-performance fiber materials in civil engineering.

[0003] In the use of wedge-type anchors for carbon fiber reinforced composite (CFRP) plates, the existing technology involves placing the CFRP plate inside the wedge-type anchor. During tensioning, the CFRP plate is prone to sliding inside the wedge-type anchor, resulting in stress concentration on the CFRP plate. Furthermore, existing tensioning tools are usually fixed to the device during use, affecting the compactness of the anchoring end of the device.

[0004] However, the applicant believes that the shortcomings are: 1. During use, the CFRP plate is prone to sliding on the inside of the device during the tensioning process, which causes stress to concentrate on the CFRP plate and lead to CFRP plate breakage; 2. At the same time, after the tensioning step, it is usually not easy to remove the tensioning structure, which affects the compactness of the anchoring end of the device.

[0005] To address this issue, we propose a clip-type anchor for carbon fiber reinforced composite plates. Utility Model Content

[0006] The purpose of this invention is to provide a clip-type anchor for carbon fiber reinforced composite material plates to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a clamp-type anchor for a carbon fiber reinforced composite material plate, comprising a fixed outer frame, a fixing structure, the fixing structure including a fixed outer frame, a mounting groove, a positioning block, a positioning insert, a fixing bolt, a fixing clamp, a mounting groove, a fixing insert, a connecting cylinder, a fixing top block, and a clamping pad; and a push-pull structure, the push-pull structure including a mounting push block, a feed inlet, a force transmission sleeve, a connecting insertion hole, a tension rod, a fixing round block, and a fixing nut.

[0008] Preferably, the inner middle part of the fixed outer frame is provided with an installation groove, a positioning block is fixedly installed at one end of the fixed outer frame, and a positioning insert is inserted into the bottom end of one end of the fixed outer frame.

[0009] Preferably, both sides of the positioning insert are threaded with fixing bolts, and a fixing clamp is slidably installed on the inner side of the fixing outer frame, with an installation groove formed in the middle of the surface of the fixing clamp.

[0010] Preferably, a fixing insert is fixedly installed at one end of the fixing clamp, a connecting cylinder is welded to the other end of the fixing clamp, a fixing top block is fitted to the top of the fixing clamp, and the fixing clamp is connected and fixed to the fixing top block by bolts.

[0011] Preferably, a clamping pad is fixedly installed on the bottom surface of the fixed top block near the middle part, and an installation push block is slidably installed on one end of the fixed clamping block and the fixed top block. A feed port is provided on one end surface of the installation push block near the bottom end.

[0012] Preferably, a force transmission sleeve is fixedly installed at the top of the feed inlet, and a connection hole is opened on the surface of the mounting push block near the four corners.

[0013] Preferably, a tension rod is inserted into the inner side of the connecting socket, a fixing block is slidably installed on the outer side of the tension rod, and a fixing nut is threaded onto the outer side of one end of the tension rod.

[0014] This utility model provides a clip-type anchor for carbon fiber reinforced composite material plates, which has the following beneficial effects: The fixed structure allows the fixed outer frame to be installed in a designated position. Then, the CFRP sheet can be placed inside the mounting groove opened on the inner side of the fixed clamping block. The fixed top block is then attached to the fixed clamping block and fixed with bolts. When the CFRP sheet is tensioned, the clamping pad will undergo plastic deformation and adhere to the micro-unevenness on the surface of the CFRP sheet, thereby eliminating stress concentration points and converting the huge clamping force into uniformly distributed compressive stress.

[0015] The push-pull structure allows the fixing nut to be removed by rotation after the push-pull operation is completed. Then, the mounting push block can be slid to one side to make the tension rod leave the connecting hole. Finally, the tension rod in the fixing block can be rotated to make one end of the tension rod leave the connecting cylinder, which facilitates the separation of the tensioning tool and makes the anchoring end more compact.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment proposes a clip-type anchor for carbon fiber reinforced composite plates. Example 1

[0021] like Figures 1 to 3As shown, this embodiment proposes a clamp-type anchor for carbon fiber reinforced composite material plates, including a fixed outer frame 1, a fixing structure, the fixing structure including the fixed outer frame 1, a mounting groove 2, a positioning block 3, a positioning insert 4, a fixing bolt 5, a fixing clamp 6, a mounting groove 7, a fixing insert 8, a connecting cylinder 9, a fixing top block 10, and a clamping pad 11; and a push-pull structure, the push-pull structure including a mounting push block 12, a feed port 13, a force transmission sleeve 14, a connecting insertion hole 15, a tension rod 16, a fixing round block 17, and a fixing nut 18. The inner middle part of the fixed outer frame 1 has a mounting groove 2, and one end of the fixed outer frame 1... A positioning block 3 is fixedly installed. A positioning plug 4 is inserted into the bottom end of one end of the fixed outer frame 1. Fixing bolts 5 are threaded on both sides of the positioning plug 4. A fixing clamp 6 is slidably installed on the inner side of the fixed outer frame 1. An installation groove 7 is opened in the middle part of the surface of the fixing clamp 6. A fixing plug 8 is fixedly installed at one end of the fixing clamp 6. A connecting cylinder 9 is welded to the other end of the fixing clamp 6. A fixing top block 10 is fitted to the top of the fixing clamp 6. The fixing clamp 6 is connected and fixed to the fixing top block 10 by bolts. A clamping pad 11 is fixedly installed on the bottom surface of the fixing top block 10 near the middle part. The fixed outer frame 1 can be installed through the mounting groove 2 to facilitate the installation of the device. The fixed outer frame 1 can be connected and fixed to the fixed clamping block 6 and the fixed top block 10 through the positioning block 3. The fixed clamping block 6 can be installed and positioned through the mounting groove 7. The fixed top block 10 can be attached and fixed to the CFRP board through the clamping pad 11 to reduce stress concentration.

[0022] In the above embodiment, when the device is used, the CFRP plate is first placed in the mounting groove 7 opened inside the fixing clamp 6, and then the fixing top block 7 is attached to the top of the fixing clamp 6 and fixed by bolts. When the CFRP plate is tensioned, the clamping pad 11 will undergo plastic deformation, so that the clamping pad 11 is tightly attached to the surface of the CFRP plate, reducing stress concentration and converting the huge clamping force into uniformly distributed compressive stress.

[0023] Example 2 like Figure 4 and Figure 5 As shown, based on the same concept as the above embodiment, this embodiment also proposes: a mounting push block 12 is slidably installed on one end of the fixed clamping block 6 and the fixed top block 10; a feed inlet 13 is provided on one end surface of the mounting push block 12 near the bottom end; a force transmission sleeve 14 is fixedly installed on the top of the feed inlet 13; a connecting insertion hole 15 is opened on the surface of the mounting push block 12 near the four corners; a tension rod 16 is inserted into the inner side of the connecting insertion hole 15; a fixed round block 17 is fixedly installed on the outer side of the tension rod 16; and a fixing nut 18 is threadedly connected to one end of the tension rod 16. The installation push block 12 can be used to facilitate the installation of CFRP plates through the feed port 13. The tension rod 16 can be easily disassembled through the connecting sleeve 9. The tension rod 16 can be made more stable during tensioning through the fixing block 17. The installation push block 12 can be connected and fixed through the fixing nut 18 provided at one end of the tension rod 16. The tension rod 16 can be easily disassembled through the force transmission sleeve 14.

[0024] In the above embodiment, when in use, one end of the jack can be rotated and installed on the inside of the force transmission sleeve 14. Then, the jack is used to push the installation push block 12, so that the fixing clamp block 6 and the fixing top block 10 slide towards the inside of the fixing outer frame 1. Since the fixing outer frame 1 is conical, the CFRP plate will also be tensioned when pushed, so that the fixing clamp block 6 and the fixing top block 10 are fixed to the inside of the fixing outer frame 1 from wide to narrow. Finally, the fixing nut 18 can be removed by rotation, and the installation push block 12 can be slid away from the tension rod 16. Finally, the tension rod 16 is rotated and taken out from the inside of the connecting cylinder 9, which facilitates the separation of the tensioning tool and makes the anchoring end more compact.
