Description

Technical Field

[0001] This utility model relates to the field of metal fastener technology, specifically a reverse anchoring component for old building renovation. Background Technology

[0002] To implement energy conservation and emission reduction, attaching composite insulation boards to the exterior of building walls is the most common method, and it has excellent insulation effects. The composite insulation boards are attached using a combination of adhesive and anchors. However, due to the limitations of the wall material itself, its structure is brittle and prone to powdering. The material and construction are also complex and difficult to determine during exterior installation, which is not conducive to the fixation of threaded anchors. Anchors are prone to falling off. Furthermore, because the composite insulation board needs to be pressed tightly against the wall, the tail end of the anchor needs to maintain a large force with the composite insulation board, which can easily cause wear and damage to the composite insulation board, resulting in poor reliability and frequent detachment incidents.

[0003] The prior art discloses a composite insulation board fixing anchor bolt with application number CN202222352328.2, which fixes the composite insulation board to the wall surface, uses pre-embedded pipes to reduce loosening between the anchor bolt and the wall, and uses an annular gasket structure to prevent the bolt head from damaging the composite insulation board.

[0004] However, the existing technology uses threaded rods for fixing during use. But when the threaded rods are used for fixing inside the pre-embedded pipe, the material and construction of the external wall structure are unclear, resulting in small single-point anchoring force and the effectiveness cannot be guaranteed. Utility Model Content

[0005] To address the shortcomings mentioned in the background art, the purpose of this utility model is to provide a reverse anchoring component for the renovation of old buildings, aiming to solve problems such as unstable anchoring that may occur when anchor bolts are used to anchor metal decorative panels in the prior art.

[0025] A reverse anchoring component for old building renovation, such as Figure 1 and 2 As shown, it includes an anchor plate 1, an anchor hole 2 for assisting in anchoring and fixing is opened at the top of the anchor plate 1, an anchor sleeve 3 is fixedly connected to the top of the anchor plate 1, an injection groove 4 for fixing grouting is opened at the top of the anchor sleeve 3, an overflow engagement port 5 for assisting engagement during the anchoring process is opened on the outside of the anchor sleeve 3, and a sleeve reinforcing rib 6 is fixedly connected to the outside of the anchor sleeve 3.

[0026] An anchor hole 2 for auxiliary anchoring is provided at the top of the anchor plate 1. An anchor sleeve 3 is fixedly connected to the top of the anchor plate 1. Grouting groove 4 for grouting is provided at the top of the anchor sleeve 3. Overflow bite opening 5 for auxiliary biting during anchoring is provided on the outside of the anchor sleeve 3. Sleeve reinforcing rib 6 is fixedly connected to the outside of the anchor sleeve 3. An anchor filler 7 is fixedly installed on the inside of the anchor plate 1. An auxiliary anchor plate 8 is fixedly installed at the end of the anchor sleeve 3 away from the anchor plate 1. An anchor connecting rod 9 is fixedly installed on the inside of the auxiliary anchor plate 8. An anchor inner rod 10 is fixedly installed on the inside of the anchor connecting rod 9.

[0027] Grout is injected into the grouting groove 4, allowing the grouting liquid used for anchoring to flow out from the overflow interlocking port 5 and be fixed in conjunction with the sleeve reinforcing rib 6. The grouting liquid is then discharged from the sleeve reinforcing rib 6 and fixed in conjunction with the sleeve reinforcing rib 6 after solidification.

[0028] Anchor plate 1 and anchor sleeve 3 are made of stainless steel.

[0029] Anchor plate 1 and anchor sleeve 3 are used to fix the metal decorative panel on the outside. The material is lightweight, has good durability and stability, can resist the corrosion of various chemicals, and has good waterproof performance, which can improve the stability of the anchor.

[0030] Six anchoring holes 2 are equidistantly distributed at the top of the anchor plate 1.

[0031] The six anchoring holes 2 are used to fix the grouting liquid to the rear decorative panel. The grouting liquid comes into contact with the rear decorative panel through the anchoring holes 2, and after solidification, the decorative panel and anchor plate 1 are fixed. This fixing process allows the anchor plate 1 and the decorative panel to make full contact, increasing the anchoring stability.

[0032] The diameter of the grouting groove 4 is 10-30 mm smaller than the diameter of the anchor plate 1.

[0033] Excessive or insufficient diameter difference between anchor plate 1 and grouting groove 4 will have an adverse effect on the fixing effect.

[0036] The thickness of both the anchor plate 1 and the anchor sleeve 3 is 1-3 mm.

[0037] Excessive thickness will increase weight, which may cause cracks after anchoring due to thermal expansion and contraction, making anchoring difficult. Conversely, excessive thinness will result in poor quality, which may lead to damage to the anchor body during the anchoring process due to thermal expansion and contraction, resulting in cracks and affecting the anchoring effect.

[0038] In use, first select the corresponding angle bracket for anchoring, and place and install the anchor bolt in conjunction with the decorative panel to be anchored. Then, inject grout into the grouting groove 4 at the top of the anchoring sleeve 3 for anchoring treatment. The grout enters through the grouting groove 4 and exits from the overflow interlocking port 5. It is fixed in conjunction with the sleeve reinforcing rib 6, and the front and rear ends are connected by the anchoring hole 2. During the solidification process of the grout, the anchor plate 1 is fixed by engaging with the anchoring hole 2. At the same time, the sleeve reinforcing rib 6 is also fixed to achieve the fixation of the entire anchor bolt and meet the actual use requirements in the anchoring process.

[0039] During use, polyurethane foam is injected into the gaps, PE foam strips are inserted, and the outside is sealed with silicone sealant.

[0040] This anchoring system is lightweight, has a good decorative effect, and features a built-in reverse anchoring system with high anchoring strength, making the system safe and reliable.

[0041] During the anchoring process, grout is injected inside the anchoring sleeve 3 so that the anchoring filler 7 can be filled into the grouting groove 4. Before it solidifies, the anchoring inner rod 10 is inserted so that the anchoring inner rod 10 can cooperate to perform reverse anchoring. The anchoring connecting rod 9 is used to assist in the solidification process to achieve anchoring.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
