Description

Technical Field

[0001] This utility model relates to the technical field of bridge engineering, and in particular to a connector suitable for ground anchoring and a ground anchor. Background Technology

[0002] Long-span arch bridges are often constructed using the cable-stayed, inclined-stayed method. Ground anchorage is a crucial form of foundation anchorage, used to reliably transfer the loads of the superstructure, such as guy ropes, cables, and stabilizing cables, to the concrete foundation. Traditional ground anchorage structures typically involve directly embedding multiple anchor bars into the concrete. During construction, the anchor cables must be directly connected to these exposed anchor bars.

[0003] However, this traditional method has significant technical drawbacks. First, during concrete pouring, it is difficult to maintain precise relative positions and verticality of multiple independent anchor bars, making them highly susceptible to installation position deviations due to pouring impacts, vibrations, or formwork deformation. These deviations can lead to difficulties in installing the upper tie cables and even introduce additional assembly stress due to forced connections. Second, and more critically, the tension of each tie cable acts directly on a single anchor bar, resulting in extreme stress concentration. This can easily cause localized damage at the anchor bar-concrete interface, leading to cracks that gradually propagate and severely weaken the overall anchoring effect and structural safety margin. Furthermore, the lack of effective lateral connections between the anchor bars hinders their coordinated operation, further limiting the load-bearing efficiency and reliability of the anchoring system.

[0004] Therefore, there is an urgent need in the existing technology for a new connection scheme that can effectively ensure the positioning accuracy of the ground anchor bar group, improve the stress state, avoid stress concentration, and improve the overall anchoring performance. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, such as the easy deviation of the installation position of the anchor bar of the traditional ground anchor structure, the easy occurrence of stress concentration, and the impact on the anchoring effect, and to provide a connector suitable for fastening ground anchors and a ground anchor.

[0006] In a first aspect, this utility model provides a connector suitable for ground anchors, comprising: An anchoring device, comprising an anchoring part and a connecting part, wherein the anchoring part is provided with a plurality of anchoring holes at intervals, the anchoring holes being used to accommodate a lanyard, and the connecting part being disposed on the side of the anchoring part; The base is embedded in the concrete body, and the top surface of the base protrudes from the concrete body. The base is used to connect the connecting part. The base is provided with a through hole for accommodating the ground anchor bar for anchoring. The axis of the through hole is parallel to the height direction of the base.

[0007] The distribution of anchor holes and through holes is determined according to the actual situation.

[0008] This application, by setting up an anchoring device and a base, with the anchoring device and base respectively used to connect the tie cable and the ground anchor bar, can determine the position of the tie cable and the ground anchor bar, thereby determining the spacing between two adjacent ground anchor bars and the spacing between two adjacent tie cables, minimizing stress concentration caused by adjacent ground anchor bars being too close together. Furthermore, this connector has a simple structure, is easy to operate, and helps improve construction efficiency.

[0009] Preferably, the base is provided with a limiting member, which is used to limit the displacement of the anchoring part.

[0010] Setting a limit component helps improve the structural stability of this device.

[0011] Preferably, the anchoring device is provided with a first connecting foot, and the limiting member includes a plurality of second connecting feet. The second connecting feet are disposed on both sides of the first connecting foot, and the distance between two second connecting feet located on both sides of the first connecting foot is adapted to the width of the first connecting foot.

[0012] By setting second connecting feet on both sides of the first connecting foot, and the spacing between two adjacent second connecting feet is adapted to the width of the first connecting foot, the installation position of the anchoring device can be quickly determined, and the positional deviation of the anchoring device relative to the base can be avoided, which helps to improve the accuracy of the structure and ensure the structural stability of the device as much as possible.

[0013] Preferably, the included angle between the connecting part and the base is adjustable.

[0014] The angle between the connector and the base can be adjusted when not in use, thus adapting to different terrains.

[0015] Preferably, the connecting part and the base are connected by bolts.

[0016] The connecting part and the base are connected by bolts, which not only allows for adjustment of the included angle between the connecting part and the base as needed, but also fixes the relative position of the connecting part and the base, thus improving the structural stability of the device.

[0017] Preferably, the base is provided with an anchoring stiffener, which is provided corresponding to the through hole, and is used to stiffen the ground anchor bar.

[0018] The installation of anchoring stiffeners can improve the anchoring performance of this device.

[0019] Preferably, the bottom surface of the base is provided with anchoring ribs, and the end of the anchoring ribs away from the base is provided with a hook.

[0020] The bottom surface of the base is the side facing away from the anchoring device. Anchoring ribs are provided on the bottom surface of the base, and these ribs have hooks to improve the anchoring performance of the device.

[0021] Preferably, the anchoring part is provided with at least two perforated plates and a plurality of stiffening plates, the anchoring holes are spaced apart on the perforated plates, the stiffening plates are respectively connected to two adjacent perforated plates on both sides, and the plane on which the stiffening plates are located is parallel to the axis of the anchoring holes.

[0022] The stiffening plate is placed between two adjacent perforated plates to improve the structural stability of the device. The plane of the stiffening plate is parallel to the axis of the anchor hole, which minimizes the interference between the position of the stiffening plate and the position of the fastening cable.

[0023] In a second aspect, the present invention provides a ground anchor, comprising a fastening cable, a ground anchor bar, and a connector as described above suitable for fastening the ground anchor, wherein the fastening cable is anchored to the anchoring part, the ground anchor bar passes through a through hole, and the ground anchor bar extends into the bearing platform.

[0024] A ground anchor includes a locking cable, an anchor bar, and a connector suitable for ground anchoring. It can determine the positions of the locking cable and anchor bar, thereby minimizing stress concentration and improving the anchoring performance of the structure. Furthermore, its structure is simple; after excavating the anchor pit, concrete can be poured directly into the full trench, eliminating the need to excavate a pit behind the anchor to reserve working space, reducing soil disturbance and the safety risk of water accumulation in the pit. Additionally, the ground anchor does not require pre-reserved slots for installing the cable system's wire ropes, directly preventing the wire ropes from scraping against the slots during cable hoisting, significantly reducing the safety risks of the cable system operation.

[0025] Preferably, the axis of the buckle forms an angle with the horizontal direction.

[0026] The cable's axis forms an angle with the horizontal direction, which can decompose the force into horizontal and vertical components. The horizontal component helps the ground anchor to penetrate deeper into the pier cap.
