Description

Technical Field

[0001] The utility model relates to the technical field of clip anchors, in particular to a clamp-type prestressed clip anchor. Background Art

[0002] In the field of civil engineering and construction, the anchoring of prestressed steel strands is a key link to ensure the safety and stability of the structure. The traditional clip anchor design is mainly composed of a clip, an anchor body and an anchor cover. The clip cooperates with the conical structure inside the anchor body. Through the clamping force and the tension of the prestressed steel strand, the clip is tightened in the anchor body, thereby firmly clamping the steel strand to prevent it from loosening. However, the traditional clip anchor design has some limitations. Since the anchor body is a complete ring, it must be inserted into the anchor body before the steel strand is tensioned, which increases the difficulty and complexity of construction to a certain extent. In addition, when the permanent anchor structure is damaged and needs to be replaced, the traditional clip anchor design often needs to be disassembled and replaced when the tension force is completely released, which not only affects the construction progress, but also may pose a potential threat to the safety of the structure. Therefore, in view of the inconvenience of traditional clip anchors in construction and maintenance, and the potential advantages of clip-type clip anchors in temporary anchoring and replacement of permanent anchor point structures, it is necessary to further develop and optimize the design of clip-type clip anchors to improve their application effect and convenience in actual engineering.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 4 As shown, the utility model provides a clamp-type prestressed clip anchor, comprising: a clip assembly 1, a fixing assembly 2 and an anchor 3; wherein the clip assembly comprises two detachable clips, a first clip 11 and a second clip 12, each clip having a partially conical inner cavity, and the two clips are combined via the fixing assembly to form a complete conical inner cavity for accommodating and clamping the prestressed steel strand; it should be noted that the detachable clips of the first clip 11 and the second clip 12 make the clip assembly 1 more convenient during installation and disassembly, and also facilitate the replacement or maintenance of the clips; a part of the anchor is inserted into the clip assembly and is firmly connected to the clip assembly via the fixing assembly, so as to prevent the prestressed steel strand from loosening or slipping during the stress process.

[0030] The first clamping piece 11 and the second clamping piece 12 each form a hemispherical protrusion with a partial conical inner cavity, and the first clamping surface 111, the first connecting surface 112, the second clamping surface 121 and the second connecting surface 122 are respectively provided on both sides; the first clamping surface 111 and the second clamping surface 121 are parallel to each other and are both provided with corresponding first reserved holes 13; the first connecting surface is a paper-shaped hook, and its opening faces the second connecting surface; the second connecting surface has a convex portion, which is embedded in the groove portion of the paper-shaped buckle and locked with each other.

[0031] The fixing assembly 2 includes an elastic washer 21, a nut 22 and a bolt 23; the bolt passes through the first reserved hole 13 to press the elastic washer 24 and is tightened by the nut, such as the type 1 hexagonal nut C grade M12, the hexagonal head bolt full thread M12×35 and the flat washer chamfered type A grade 12×2.5; the fixing assembly 2 of this embodiment not only maintains the original elastic washer 21, nut 22 and bolt 23, but also introduces a self-locking thread design. This self-locking thread adopts a special tooth shape design, so that the bolt can generate a strong self-locking force during the tightening process, effectively preventing loosening caused by vibration or impact. In addition, the elastic washer 21 adopts a new type of high-elastic rubber material, which has better resilience and wear resistance, and can better adapt to the deformation of the clip assembly during the force process.

[0032] An interlocking mechanism is provided between the anchor 3 and the clip assembly 1; the interlocking mechanism includes a protruding portion provided on the anchor 3, and a groove portion provided at a corresponding position of the clip assembly 1. When the anchor 3 and the clip assembly 1 are combined, the protruding portion is embedded in the groove portion to achieve locking, thereby ensuring that the anchor and the clip assembly can maintain a relatively stable connection state during the stress process of the prestressed steel strand.

[0033] It should be noted that the present embodiment also takes into account the integrity and aesthetics of the structure, and the connections between the clip assembly 1, the fixing assembly 2 and the anchor 3 all adopt a smooth transition design, which not only reduces the stress concentration points, but also improves the aesthetics of the overall structure; at the same time, the surfaces of each component are treated with anti-corrosion to extend their service life; by adopting our utility model, when the permanent anchoring structure is damaged and needs to be replaced, this type of clip anchor can be conveniently installed on the steel strand while maintaining a certain tension force, forming a temporary anchoring point and replacing the permanent anchoring structure.

[0034] Example 2

[0035] Based on Example 1, this embodiment also provides another clamp-type prestressed clip anchor, in which the first clip 11 and the second clip 12 are spliced ​​by a dovetail groove, and corresponding second reserved holes 14 are provided at a position perpendicular to the splicing point, and are also fixed by the fixing assembly in Example 1; then this structure does not need to extend the first clamping surface 111, the first connecting surface 112, the second clamping surface 121 and the second connecting surface 122.

[0036] Example 3

[0037] Based on Example 1, this embodiment further provides a docking mechanism between the anchor 3 and the clip assembly 1; the docking mechanism includes a lock buckle on the anchor 3, and a lock groove at the corresponding position of the clip assembly 1. When the anchor 3 and the clip assembly 1 are combined, the lock buckle is accurately docked and locked by rotating / pushing into the lock groove; for example, the lock buckle of the anchor 3 adopts a special shape and structure, so that it can be quickly and accurately inserted when docking with the lock groove of the clip assembly 1; at the same time, a spring locking mechanism is provided inside the lock buckle, and when the lock buckle is inserted into the lock groove, the spring locking mechanism can automatically pop out and firmly lock in the lock groove to achieve a fast and stable connection; in addition, the interlocking mechanism between the anchor 3 and the clip assembly 1 can be improved; in addition to the original cooperation between the raised part and the groove part, a magnetic interlocking technology is newly added; both the raised part and the groove part are embedded with strong magnets, and when they are in contact and combined, the strong suction generated by the magnet can firmly connect the two together; this magnetic interlocking technology not only enhances the stability of the connection, but also makes the installation and disassembly process more convenient and efficient.
