DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1 and Figure 2A prestressed carbon fiber plate anchor rocker arm structure includes a fixed anchor 1 and a tension anchor 2. The fixed anchor 1 includes a first fixing plate 101, with fifth screw holes 102 formed on both sides of the first fixing plate 101. The first fixing plate 101 is fixed to one end of the building to be reinforced by bolts. The tension anchor 2 includes a tension plate 201, a second fixing plate 202, a jack 203, a movable plate 204, and a tension rod 205. The second fixing plate 202 has fourth screw holes 206 formed on both sides. The second fixing plate 202 is fixed to the other end of the building to be reinforced by bolts. The jack 203 is mounted on the second fixing plate 202. The movable plate 204 is connected to the jack 203. Sliding sleeves are provided on both sides of the second fixing plate 202. Two tension rods 205 are slidably connected to the two sliding sleeves. One end of the tension rod 205 is connected to the movable plate 204, and the other end is connected to both sides of the tension plate 201. The movable plate is pushed by the jack, and the movable plate pulls the tension plate to move through the pull rod.

[0017] The first fixed plate 101 and the tensioning plate 201 are both fixed with adapter blocks 5. The opposing surfaces of the two adapter blocks 5 are provided with movable cavities, and a rocker arm is movably connected through the movable cavities. Specifically, the bottom of the adapter block 5 located in the movable cavity is provided with a first screw hole, and the top of the adapter block 5 is provided with a second screw hole, and the first screw hole and the second screw hole are threadedly connected with a screw rod 6. The rocker arm 3 includes a positioning block 301 and two connecting plates 302 fixedly connected to one end of the positioning block, one of which is located in the movable cavity and is rotatably connected to the screw rod 6, and the other connecting plate 302 is located above the adapter block 5 and is rotatably connected to the screw rod 6. The upper end of the screw rod 6 passes through the adapter block 5, and the protruding end is threadedly connected to a fastening nut 7. By screwing the fastening nut 7 so that it is pressed tightly against the upper connecting plate 302, the rocker arm 3 can be kept fixed and prevented from swinging.

[0018] Slots 303 are defined at opposing ends of the two positioning blocks 301. Slots 303 have serrated inner walls, and the two rocker arms are connected to the carbon fiber plates 4 through these slots. The serrated slots 301 increase the contact area with the carbon fiber plates, improving friction. Third screw holes 304 are located on either side of the positioning blocks 301. Once the carbon fiber plates 4 are inserted into the slots 303, bolts engage the third screw holes 304, securing them within the slots 303.

[0019] The working principle of this utility model is as follows: a first fixed plate 101 and a second fixed plate 202 are fixed to the ends of a building, and the ends of the carbon fiber plate 4 are connected to two rocker arms 3. When the jack 203 is extended, it pushes the movable plate 204, which pulls the tensioning plate 201 via the pull rod 205, thereby tightening the carbon fiber plate 4 and maintaining the stress. In the event of installation deviation, the fastening nut 7 is loosened. During the tensioning process, the rocker arms 3 can align the tensioning end and the fixed end, preventing the carbon fiber plate 4 from deviating and keeping the carbon fiber plates in a straight line. There is no need to disassemble the anchor, which greatly reduces the cost of manpower and material resources.
