Description

Technical Field

[0001] This utility model relates to the field of rock and soil anchoring technology, specifically to an anchor rod connection structure. Background Technology

[0002] As self-drilling anchors are used in different application scenarios, the requirements for anchor bolt length also vary. To meet the needs of different scenarios, anchor bolts need to be able to be cut short and lengthened at will during use, and the part used for lengthening is the connecting sleeve. Based on application requirements, the design of the connecting sleeve must ensure good sealing performance and complete transmission of anchor bolt force. The tightness of the fit between the connecting sleeve and the anchor bolt is the key to the design.

[0003] The existing anchor bolts and connecting sleeves are not precision-machined and have low accuracy. The fit between the two is difficult to control. If it is too tight, there is a risk of poor engagement; if it is too loose, there is a risk of uneven strength. In addition, a connection of a certain specification of anchor bolt usually requires a matching connecting sleeve of the same specification, and conventional connecting sleeves have poor applicability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an anchor bolt connection structure with the advantages of simple structure, easy processing and good versatility. It can be adapted to anchor bolts of different specifications and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anchor bolt connection structure, comprising two connectors and multiple locking rings, wherein the multiple locking rings are sleeved on the outside of the two connectors, the two connectors are arranged parallel to the anchor bolt axis, and the two connectors clamp and fix the two anchor bolts under the locking action of the multiple locking rings, and make the center holes of the two anchor bolts correspond and coincide.

[0006] Preferably, the connector has a V-shaped groove for clamping the anchor rod, and the connector is provided with a stop block for positioning the anchor rod.

[0007] Preferably, both ends of the stop block are provided with elastic pads. Under the locking action of multiple locking rings, the elastic pads corresponding to the ends of the two stop blocks are tightly fitted together. The end face formed by the two stop blocks and the four elastic pads is sealed and fitted with the end face of the anchor rod. The two stop blocks and the four elastic pads form a closed channel corresponding to the central holes of the two anchor rods.

[0008] Preferably, the locking ring is a metal ring with staggered interfaces, made of carbon steel or stainless steel. The locking ring is compressed towards the middle using pliers to fix the two anchor rods to the two connecting parts.

[0009] Preferably, the elastic pad is made of rubber or plastic and is attached to the end of the stop block with adhesive.

[0010] Preferably, the connector is a semi-circular shell or a trapezoidal shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the connection of two anchor rods is achieved by the cooperation of two connecting parts and multiple locking rings, and the connecting parts and anchor rods fit tightly; elastic pads are set at both ends of the stop block, and under the pressing force applied by the locking rings, the two stop blocks and their corresponding four elastic pads fit tightly together to form a sealing surface that matches the end face of the anchor rod, as well as a sealed channel connecting the center holes of the two anchor rods, which has good sealing performance and effectively prevents grout leakage during the grouting process; it has the advantages of simple structure, easy processing, and good versatility, and can be adapted to anchor rods of different specifications.

[0014] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0015] Please see Figure 1-3 This utility model provides a technical solution: an anchor bolt connection structure, including two connecting parts 1 and multiple locking rings 2. The multiple locking rings 2 are sleeved on the outside of the two connecting parts 1. The two connecting parts 1 are arranged parallel to the anchor bolt axis. The two connecting parts 1 clamp and fix the two anchor bolts under the locking action of the multiple locking rings 2, and make the center holes of the two anchor bolts correspond and coincide. The connection of the two anchor bolts is realized by the cooperation of the two connecting parts 1 and the multiple locking rings 2. It has good versatility, can be adapted to anchor bolts of different specifications, is not affected by the size of the anchor bolt, and the connecting parts 1 can fit tightly with the anchor bolt. Specifically, connector 1 has a V-shaped groove for clamping the anchor rod, and connector 1 is provided with a stop block 1.1 for positioning the anchor rod; both ends of the stop block 1.1 are provided with elastic pads 1.2. Under the locking action of multiple locking rings 2, the elastic pads 1.2 corresponding to the ends of the two stop blocks 1.1 are tightly fitted together, and the end face formed by the two stop blocks 1.1 and the four elastic pads 1.2 is sealed and fitted with the end face of the anchor rod. Moreover, the two stop blocks 1.1 and the four elastic pads 1.2 form a sealed passage corresponding to the central holes of the two anchor rods. The anchor rods are clamped and axially limited by two V-groove connectors 1 and stop blocks 1.1, which effectively ensures that the center holes of the two anchor rods to be connected are accurately aligned and coincident, significantly improving the connection accuracy and avoiding stress concentration or grouting channel blockage caused by misalignment. The two stop blocks 1.1 and their corresponding four elastic pads 1.2 fit tightly together to form a sealing surface that matches the end face of the anchor rod and a sealed channel connecting the center holes of the two anchor rods. The sealing performance is good and effectively prevents grout leakage during the grouting process. Specifically, the locking ring 2 is a metal ring with staggered interfaces, made of carbon steel or stainless steel. The locking ring 2 is compressed towards the center using pliers to fix the two anchor rods to the two connecting parts 1. In use, the two anchor rods are first placed inside the connecting parts 1, pressing against the stop position 1.1. All locking rings 2 are clamped and compressed towards the center with pliers. Once the anchor rods and connecting parts 1 are tightly fitted, they can be released. The elastic pad 1.2 is also compressed during the compression of the locking ring 2, achieving a tight seal between the upper and lower parts. This eliminates the need for welding or complex tools, greatly simplifying the on-site installation process, improving construction efficiency, and facilitating disassembly and reuse. Specifically, the elastic pad 1.2 is made of rubber or plastic and is glued to the end of the stop block 1.1; in addition, the connector 1 is a semi-circular shell or a trapezoidal shell.

[0016] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents in the content of this utility model.
