Technical Field
[0001] This utility model relates to the field of anchor bolts, and in particular to a quick-installation fixing head for a single anchor bolt. Background Technology
[0002] In engineering construction, anchor bolts are widely used for support and reinforcement in geotechnical engineering and underground engineering. Anchor bolt technology originated in mining and tunnel engineering to enhance the stability of rock and soil, prevent collapses and landslides, and ensure engineering safety. With the development of technology, the application scope of anchor bolts has gradually expanded to multiple fields such as bridges, high-rise building foundations, basements, tunnels, and slope support.
[0003] Existing technologies, such as the utility model patent with publication number CN214091926U, disclose an anchor bolt. This patent includes a limiting tube with a first through hole; a rod body passing through the first through hole; and a limiting chain connecting the limiting tube and the rod body on the same side. Using this utility model anchor bolt, by sleeved with a limiting tube on the outside of the rod body and connecting the rod body and the limiting tube on the same side with a limiting chain, the friction between the anchor bolt and the inner wall of the borehole is controlled by the extension and contraction of the limiting chain. This allows the anchor bolt to be freely removed from the borehole for reuse, saving significant material costs.
[0004] In daily use, it has been found that welding is often used to fix the anchor head and anchor rod. However, welding requires a lot of materials and equipment. Especially in support and reinforcement work, a large number of anchor rods are required, which makes the welding process complicated and requires a lot of equipment. This not only increases the construction cost, but also results in low installation efficiency of anchor head and anchor rod.
[0005] Therefore, it is necessary to provide a new type of quick-installation fixing head for single anchor bolts to solve the above-mentioned technical problems. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0028] Please see Figures 1 to 4The present invention provides a quick-installation fixing head for a single anchor bolt, comprising: an anchor bolt body 1 and an anchor head 2. The arc surface of the anchor bolt body 1 is fixed to the anchor head 2 by means of an adjustment structure 6. A grout stop plug 3 is installed on the arc surface of the anchor bolt body 1. A pad 4 is installed on the arc surface of the anchor bolt body 1. A nut 5 is installed on the arc surface of the anchor bolt body 1. The adjustment structure 6 is provided on the arc surface of the anchor bolt body 1.
[0029] In the embodiments of this utility model, please refer to Figures 2 to 4 The adjusting structure 6 includes a connecting ring 603, which is fixedly connected to the anchor rod body 1. Two connecting rods 607 are rotatably connected to the inner wall of the connecting ring 603. Limiting plates 608 are fixedly connected to the arc surfaces of both connecting rods 607. A connecting groove 609 is provided on one side of the limiting plate 608. A connecting ring 601 is fixedly connected to one side of the anchor head 2. The connecting ring 601 is slidably connected to the anchor rod body 1. Two fixing plates 602 are fixedly connected to one side of the connecting ring 601. The two fixing plates 602 are slidably connected to the connecting ring 603. Two positioning grooves 604 are formed on the arc surface of anchor 1. A fixing rod 605 is fixedly connected to the inner wall of each positioning groove 604. A limit frame 606 is slidably connected to the inner wall of the connecting ring 601. The dimensions of the positioning grooves 604 and the limit plate 608 are compatible, and the dimensions of the fixing rods 605 and the connecting groove 609 are compatible. By setting the adjustment structure 6, the anchor head 2 and the anchor rod body 1 can be easily and quickly installed and fixed, avoiding the cumbersome operation of traditional welding, thus improving the efficiency of installing and fixing the anchor head 2 and the anchor rod body 1. One side of the limit plate 608 is fixedly connected to... An auxiliary rod 610 with a circular cross-section is included. The auxiliary rod 610 can move the limiting plate 608, facilitating control of the limiting plate 608. An anti-slip sleeve 611 is fixedly connected to the arc surface of the auxiliary rod 610. The anti-slip sleeve 611 has anti-slip textures to increase the friction of the auxiliary rod 610, preventing hand slippage when moving it. A soft pad 612, made of rubber, is fixedly connected to one side of the limiting plate 608. Due to the elasticity of the soft pad 612, it... This allows the limiting plate 608 to fit more tightly into the positioning groove 604. Several positioning rods 613 are fixedly connected to one side of the connecting ring 601. The positioning rods 613 and the connecting ring 603 are slidably connected. The positioning rods 613 can make the connecting ring 601 and the connecting ring 603 more stable and can also play a positioning role. Two limiting blocks 614 are fixedly connected to the arc surface of the limiting frame 606. The limiting blocks 614 can limit the limiting frame 606 and prevent the limiting frame 606 from detaching when it moves inside the connecting ring 601.
[0030] The working principle of the quick-installation fixing head for a single anchor rod provided by this utility model is as follows: By setting the adjustment structure 6, the anchor head 2 is moved first, driving the connecting ring 601 to move, so that the connecting ring 601 is inserted into the anchor rod body 1. When the connecting ring 601 moves, it will drive the fixing plate 602 to move, so that the fixing plate 602 is inserted into the connecting ring 603. Then, the limiting plate 608 is rotated, driving the connecting rod 607 to rotate inside the connecting ring 603 until the limiting plate 608 is inserted into the positioning groove 604 of the connecting ring 601. At the same time, the fixing rod 605 in the positioning groove 604 will be inserted into the connecting groove 609. Then, the limiting frame 606 is moved inside the connecting ring 601, so that the limiting frame 606 blocks the limiting plate 608. Since the anchor rod body 1 and the anchor head 2 are inserted in one direction, the limiting frame 606 will not move arbitrarily and does not need to be fixed. Then, the anchor head 2 is moved into the connecting ring 603. 2. Insert the anchor bolt body 1 into the pre-drilled hole. Install the grout stop plug 3 at the hole opening to prevent grout leakage. Place the pad 4 on one side of the grout stop plug 3 to evenly distribute the pressure. Finally, tighten the nut 5 to ensure overall stability and strength. The auxiliary rod 610 can drive the limit plate 608 to move, achieving the effect of convenient control of the limit plate 608. The anti-slip sleeve 611 can increase the friction of the auxiliary rod 610 and prevent the personnel from slipping when moving the auxiliary rod 610. Since the soft pad 612 is elastic, it can make the limit plate 608 more tightly inserted into the positioning groove 604. The positioning rod 613 can make the connecting ring 601 and the connecting ring 603 more stable and also play a positioning role. The limit block 614 can limit the limit frame 606 to prevent the limit frame 606 from detaching when moving inside the connecting ring 601.
