Technical Field
[0001] This utility model relates to the field of building structure reinforcement technology, specifically a building external insulation reinforcement device. Background Technology
[0002] During long-term use, building exterior wall insulation systems are prone to hollowing, cracking, and even detachment due to factors such as wind load, temperature stress, and material aging, posing serious safety hazards. Existing reinforcement methods, such as anchor bolts or adhesives, have the following drawbacks: First, ordinary anchor bolts are only anchored in the base wall and cannot provide effective overall restraint for insulation layers that have become hollow. Furthermore, metal anchor bolts penetrating the insulation layer can create thermal bridges, reducing the insulation effect of the wall. Second, point anchoring can easily cause stress concentration around the anchor point under strong wind pressure, leading to localized damage to the insulation board. To address these issues, the inventor proposes a building exterior insulation reinforcement device to solve the above problems. Utility Model Content
[0003] To address the current problems of insufficient reinforcement and potential thermal bridging during the reinforcement process in building external insulation, which reduces the insulation effect of the wall, the purpose of this utility model is to provide a building external insulation reinforcement device.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a building external insulation reinforcement device, comprising a reinforcement component, wherein the reinforcement component includes an anchor rod, an injection port is provided through the end face of the anchor rod, a heat insulation sleeve is fixedly sleeved on the side wall of the anchor rod, an adhesive outlet is provided on the side wall of the anchor rod and on one side of the heat insulation sleeve, one end of the adhesive outlet extends into the injection port, an external thread is provided on the side wall of the anchor rod and on the other side of the heat insulation sleeve, a clamping plate is provided on one side of the anchor rod, a through opening is provided through the middle of the side wall of the clamping plate, the anchor rod is located in the through opening, and a nut is provided on the side of the clamping plate opposite to the anchor rod, the nut corresponding to and cooperating with the external thread.
[0005] Preferably, the axis of the glue outlet is perpendicular to the axis of the glue injection port. There are several glue outlets, arranged in an array around the axis of the anchor rod. The reinforcement assembly also includes a pushing assembly, which includes a crossbar. One end of the crossbar is fixedly connected to a piston, and the other end is fixedly connected to a handle. The piston corresponds to and cooperates with the glue injection port. An exterior wall is provided on one side of the clamping plate, comprising a base wall and an insulation layer. When reinforcing the insulation layer on the base wall, holes are drilled in the constructed exterior wall until they penetrate the insulation layer to a certain depth into the base wall. Then, an external electric wrench or other tools can be used to tighten the anchor rod, screwing it into the base wall to complete the fixing of the anchor rod. Subsequently, an external vinyl ester resin or epoxy resin-based injection adhesive can be injected into the injection port. By placing the piston in the pushing assembly at the injection port and pushing the piston with the handle, the adhesive can be squeezed out through the outlet to fill the gap between the anchor rod and the drilled hole, thereby improving the fixing strength of the anchor rod. The inner wall of the port is fixedly connected with a protrusion, and the side wall of the anchor rod is provided with a groove at the external thread. The protrusion and the groove correspond and cooperate. The heat insulation sleeve on the anchor rod is made of rubber. When the anchor rod is inserted and fixed in the outer wall, the heat insulation sleeve is used to be embedded in the insulation layer. The function of the heat insulation sleeve is to cut off or significantly reduce the thermal bridge formed by the metal anchor rod to ensure the overall thermal insulation performance of the building.
[0006] Preferably, a convex ring is fixedly connected to the side of the clamping plate facing away from the insulation sleeve, and a sealing ring is fixedly connected to the outer wall of the convex ring. The opening is located inside the ring opening of the convex ring. A sleeve is provided on one side of the clamping plate, and the sleeve corresponds to and engages with the convex ring. The opening size of the sleeve is larger than the outer diameter of the nut. The side of the clamping plate facing the anchor rod has anti-slip texture. The inside of the clamping plate is wrapped with cross-shaped reinforcing ribs. After the anchor rod is inserted and fixed to the outer wall, the clamping plate is fitted onto the anchor rod exposed outside the outer wall. Through the mutual cooperation of the protrusion and the groove, the clamping plate is pushed to move horizontally until the clamping plate contacts the outer wall of the insulation layer, thus clamping the rod. The side of the plate facing the anchor rod has anti-slip texture to increase friction with the insulation layer. Next, the nut is aligned with the end of the anchor rod and tightened. Through the interaction between the nut and the external thread, the nut moves closer to the outer wall, pushing the clamping plate to tightly hold the insulation layer, thereby reinforcing hollow or unstable insulation layers. Afterward, the sleeve is fitted onto the convex ring. The sealing ring ensures that the sleeve fits tightly onto the convex ring, preventing the sleeve from easily falling off and improving the sealing between the sleeve and the convex ring. This prevents moisture from entering the sleeve opening through the connection between the sleeve and the convex ring, thus reducing corrosion to the nut.
[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a reliable reinforcement. The clamping plate tightly holds the insulation layer, thereby reinforcing hollow or unstable insulation layers. When installing the anchor rod, the interaction between the anchor rod and the adhesive during tightening enhances the fixing strength of the anchor rod, preventing the anchor rod embedded in the base wall from easily loosening and thus avoiding affecting the reinforcement effect of the insulation layer.
[0008] 2. This utility model can effectively cut off or reduce the thermal bridges formed by metal anchor rods to ensure the overall thermal insulation performance of the building. In addition, the clamping plate can increase the contact area with the insulation layer, evenly disperse the concentrated stress borne by the anchor point, and avoid local crushing.

[0020] By adopting the above technical solution, an outer wall 1 is provided on one side of the clamping plate 11. The outer wall 1 includes a base wall 2 and an insulation layer 3. When it is necessary to reinforce the insulation layer 3 located on the base wall 2, a hole is drilled in the constructed outer wall 1 until it penetrates the insulation layer 3 to a certain depth into the base wall 2. Then, an external electric wrench or other tools can be used to tighten the anchor rod 5 so that it is screwed into the base wall 2 to complete the fixing of the anchor rod 5. After that, an external vinyl ester resin or epoxy resin-based injection anchoring adhesive can be injected into the injection port 10. By placing the piston 19 in the pushing assembly 17 at the injection port 10 and pushing the piston 19 with the handle 20, the adhesive can be squeezed out through the outlet 6 to fill the gap between the anchor rod 5 and the drilled hole, thereby improving the fixing strength of the anchor rod 5.
[0021] The inner wall of the through 12 is fixedly connected with a protrusion, and the side wall of the anchor rod 5 is provided with a groove 9 at the external thread 8. The protrusion and the groove 9 correspond to and cooperate with each other.
[0022] By adopting the above technical solution, the heat insulation sleeve 7 set on the anchor rod 5 is made of rubber. When the anchor rod 5 is inserted and fixed in the outer wall 1, the heat insulation sleeve 7 is used to be embedded in the insulation layer 3. The function of the heat insulation sleeve 7 is to cut off or significantly reduce the thermal bridge formed by the metal anchor rod 5, so as to ensure the overall thermal insulation performance of the building.
[0023] A convex ring 13 is fixedly connected to the side of the clamping plate 11 facing away from the heat insulation sleeve 7. A sealing ring 14 is fixedly connected to the outer wall of the convex ring 13. The through-hole 12 is located inside the ring opening of the convex ring 13. A sleeve 16 is provided on one side of the clamping plate 11. The sleeve 16 corresponds to and engages with the convex ring 13. The opening size of the sleeve 16 is larger than the outer diameter of the nut 15. The side of the clamping plate 11 facing the anchor rod 5 is provided with anti-slip texture. The inside of the clamping plate 11 is wrapped with cross-shaped reinforcing ribs. The clamping plate 11 is made of nylon, glass fiber reinforced plastic or other high-strength composite materials.
[0024] By adopting the above technical solution, after the anchor rod 5 is inserted and fixed to the outer wall 1, the clamping plate 11 is fitted onto the anchor rod 5 exposed outside the outer wall 1. Through the mutual cooperation of the protrusion and the groove 9, the clamping plate 11 is pushed to move horizontally until the clamping plate 11 contacts the outer wall of the insulation layer 3. The side of the clamping plate 11 facing the anchor rod 5 is provided with anti-slip texture to increase the friction with the insulation layer 3. Then, the nut 15 is aligned with the end of the anchor rod 5 and the nut 15 is tightened. Through the mutual cooperation of the nut 15 and the external thread 8, the nut 15... 5. Move towards the outer wall 1 to push the clamping plate 11, so that the clamping plate 11 tightly presses the insulation layer 3, thereby reinforcing the hollow or unstable insulation layer 3. Then, put the sleeve 16 on the convex ring 13. The sealing ring 14 can make the sleeve 16 tightly fit on the convex ring 13, so as to prevent the sleeve 16 from easily falling off the convex ring 13, and also improve the sealing between the sleeve 16 and the convex ring 13, so as to prevent moisture from entering the cylinder opening through the connection between the sleeve 16 and the convex ring 13, thereby reducing the corrosion of the nut 15.
[0025] Working principle: When using this utility model, the exterior wall 1 includes a base wall 2 and an insulation layer 3. When it is necessary to reinforce the insulation layer 3 located on the base wall 2, first drill holes in the constructed exterior wall 1 until the insulation layer 3 is penetrated to a certain depth into the base wall 2. Then, external tools such as electric wrenches can be used to tighten the anchor rod 5 so that it is screwed into the base wall 2 to complete the fixing of the anchor rod 5. Then, external vinyl ester resin or epoxy resin-based injection anchoring adhesive can be injected into the injection port 10. By placing the piston 19 in the pushing assembly 17 at the injection port 10 and pushing the piston 19 with the handle 20, the adhesive can be squeezed out through the outlet 6 to fill the gap between the anchor rod 5 and the drilled hole, thereby improving the fixing strength of the anchor rod 5. After the pushing is completed, the pushing assembly 17 needs to be removed from the injection port 10 to avoid affecting subsequent operations. Furthermore, when the anchor rod 5 is inserted and fixed inside the outer wall 1, the heat insulation sleeve 7 must be embedded inside the insulation layer 3. The function of the heat insulation sleeve 7 is to cut off or reduce the thermal bridge formed by the metal anchor rod 5 in order to ensure the overall thermal insulation performance of the building. Next, after the anchor rod 5 is inserted and fixed to the outer wall 1, the clamping plate 11 is fitted onto the anchor rod 5 exposed outside the outer wall 1. Through the mutual cooperation of the protrusion and the groove 9, the clamping plate 11 is pushed to move horizontally until the clamping plate 11 contacts the outer wall of the insulation layer 3. The side of the clamping plate 11 facing the anchor rod 5 is provided with anti-slip texture to increase the friction with the insulation layer 3. Then, align the nut 15 with the end of the anchor rod 5, and tighten the nut 15. Through the mutual cooperation between the nut 15 and the external thread 8, the nut 15 moves towards the outer wall 1 to push the clamping plate 11, so that the clamping plate 11 tightly presses the insulation layer 3, thereby reinforcing the hollow or unstable insulation layer 3. Then, the sleeve 16 is fitted onto the convex ring 13. The sealing ring 14 ensures that the sleeve 16 is tightly fitted onto the convex ring 13, preventing the sleeve 16 from easily falling off the convex ring 13 and improving the sealing between the sleeve 16 and the convex ring 13. This prevents moisture from entering the cylinder opening through the connection between the sleeve 16 and the convex ring 13, thereby reducing the corrosion of the nut 15.
