Description

Technical Field

[0001] This utility model belongs to the field of foundation construction technology and relates to a new type of large-diameter anchor rod centering and positioning metal bracket. Background Technology

[0002] Traditional anti-buoyancy anchors are no longer sufficient to meet the anti-buoyancy requirements of buildings. Therefore, in the field of geotechnical engineering, in-depth research has been conducted on the construction technology application of anti-buoyancy projects. Technological innovations have been made in aspects such as the diameter, depth, and structural dimensions of anti-buoyancy anchors to meet the anti-buoyancy requirements of buildings. However, due to the significant difference in diameter between large-diameter anti-buoyancy anchors and the anchor body, it is easy to cause eccentricity of the anchor body during construction, leading to changes in the stress mechanism and structural integrity, thus greatly reducing construction quality and posing a significant potential hazard to anti-buoyancy projects.

The inner steel ring is nested inside the outer steel ring, and the outer and inner steel rings are supported by a support member. At least two load-bearing rods are inserted into the inner steel ring. A screw is threaded onto one side of the inner steel ring, and the end of the screw abuts against the surface of the corresponding load-bearing rod. A pad is provided on one side of the inner wall of the inner steel ring.

[0005] In the aforementioned novel large-diameter anchor rod centering and positioning metal bracket, the support member is a ring structure, and multiple steel bars are fixedly arranged at equal intervals on the surface of the support member. The steel bars are HPB300 grade steel bars, and the diameter of the steel bars is 10mm-12mm.

[0006] In the aforementioned novel large-diameter anchor bolt centering and positioning metal bracket, the outer steel ring has a size of 200mm-300mm and a height of 10mm-30mm.

[0007] In the aforementioned novel large-diameter anchor bolt centering and positioning metal bracket, the inner steel ring has a size of 32mm-80mm and a height of 30mm-60mm.

[0008] In the aforementioned novel large-diameter anchor bolt centering and positioning metal bracket, the pad is a metal steel plate.

[0009] In the aforementioned novel large-diameter anchor rod centering and positioning metal bracket, the outer diameter of the support member is adapted to the inner diameter of the outer steel ring, and the inner diameter of the support member is adapted to the outer diameter of the inner steel ring.

[0010] Compared with the prior art, the beneficial effects of this utility model are: through the cooperation of the outer steel ring, the inner steel ring and the support, the central load-bearing rod can be centered and positioned, which can prevent the load-bearing rod from being eccentric during construction, and avoid the load-bearing rod being eccentric during construction, which would cause changes in the force mechanism and force structure, thereby affecting the construction quality.

[0013] 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.

[0014] Please see Figure 1-2 This utility model provides a technical solution for a novel large-diameter anchor bolt centering and positioning metal bracket: according to Figure 1-2 As shown, a novel large-diameter anchor rod centering and positioning metal bracket includes an outer steel ring 7, an inner steel ring 2, and a force-bearing rod 6. The inner steel ring 2 is nested inside the outer steel ring 7, and the outer steel ring 7 and the inner steel ring 2 are supported by a support member 4. At least two force-bearing rods 6 are inserted into the inner steel ring 2. A screw 3 is threadedly connected to one side of the inner steel ring 2, and the end of the screw 3 abuts against the surface of the corresponding force-bearing rod 6. A pad 1 is provided on one side of the inner wall of the inner steel ring 2.

[0015] Specifically, through the cooperation of the outer steel ring 7, the inner steel ring 2 and the support 4, the central load-bearing rod 6 can be centered and positioned, which can prevent the load-bearing rod 6 from being off-center during construction. This avoids the load-bearing rod 6 being off-center during construction, which would cause changes in the force mechanism and force structure, thus affecting the construction quality.

[0016] according to Figure 1 and Figure 2 As shown, the support member 4 is a ring structure, and multiple steel bars 5 are fixedly arranged at equal intervals on the surface of the support member 4. The steel bars 5 are HPB300 grade steel bars 5, and the diameter of the steel bars 5 is 10mm-12mm.

[0017] The outer steel ring 7 has a size of 200mm-300mm and a height of 10mm-30mm.

[0018] The inner steel ring 2 has a size of 32mm-80mm and a height of 30mm-60mm.

[0019] The pad 1 is made of metal steel plate. The pad 1 has high structural strength and can stabilize the centering of the load-bearing rod 6.

[0020] The outer diameter of the support member 4 is matched with the inner diameter of the outer steel ring 7, and the inner diameter of the support member 4 is matched with the outer diameter of the inner steel ring 2.

[0021] Specifically, the support member 4 can limit and fix the outer steel ring 7 and the inner steel ring 2, thereby ensuring the stability of the metal bracket.

[0022] Working principle: This utility model discloses a novel large-diameter anchor rod centering and positioning metal bracket. When assembling the centering and positioning metal bracket, firstly, a fine tap is used to tap the side of the inner steel ring 2. After tapping, it should be easy to install the 6mm-10mm screw 3. Then, the inner steel ring 2 is nested with the force-bearing rod 6, and the screw 3 is turned into the tapped threaded hole. The screw 3 is tightened by adjusting the shim 1, thereby ensuring that the force-bearing rod 6 is located in the middle. Next, the support 4 is nested and fixed with the inner steel ring 2. Then, the outer steel ring 7 is nested and fixed with the inner steel ring 2, completing the assembly of the centering and positioning metal bracket.
