Description

Technical Field

[0001] The utility model relates to the technical field of anchor devices, and particularly relates to a multi-hole anchor device. Background Technique

[0002] An anchor device refers to a permanent anchoring device used in prestressed concrete. It is an anchoring tool in post-tensioned structures or components to maintain the tension of prestressed tendons and transfer it to the interior of concrete, also known as a prestressed anchor device. The multi-hole anchor device has multiple groups of anchor holes arranged on its surface, facilitating the anchoring of multiple groups of prestressed tendons.

[0003] Patent No. CN202221848685.1 discloses an anchor device, including a force-bearing part and a first cylindrical part connected to each other; the first cylindrical part is provided with a threaded through-hole that extends from the first cylindrical part to the force-bearing part. A stepped surface is formed between the force-bearing part and the first cylindrical part, and the stepped surface is located at the end surface of the force-bearing part close to the first cylindrical part. A relatively long first cylindrical part is provided below the force-bearing part of the anchor device, increasing the connection strength between the anchor device and the anti-floating anchor bar. More importantly, the height can be adjusted as needed during installation to ensure that all anchor devices are at the same height, enabling the concrete floor slab to be stressed evenly and effectively solving the problem of inconsistent heights of anchor devices during anchor construction.

[0004] Existing multi-hole anchor devices have the following disadvantages: All multi-hole anchor devices are clamped and fixed once, and are prone to slipping and loosening, and the stability cannot be improved by secondary clamping. For this reason, we propose a multi-hole anchor device. Summary of the Invention

[0005] The main purpose of the utility model is to provide a multi-hole anchor device, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A multi-hole anchor device includes a through-hole, a clamping plate, an anchor plate, and a guide rod. The periphery of the top of the anchor plate is penetrated with anchor holes, and split collets with a clamping function are arranged in the anchor holes. A plug-in groove is formed on the periphery of the top of the anchor plate. A clamping plate is pressed on the upper end of the anchor plate, and a plug-in ring corresponding to the plug-in groove is welded to the periphery of the bottom of the clamping plate. Tightening hoops are arranged at equal distances on the top of the clamping plate. Threaded holes are arranged at equal distances on the periphery of the anchor plate, and locking bolts penetrate through the threaded holes.

[0008] Furthermore, a guide rod is welded to the center of the top of the anchor plate, and a guide sleeve corresponding to the guide rod is arranged at the center of the clamping plate. By sleeving the guide rod in the guide sleeve, rapid positioning is achieved, and the stability is high.

[0009] Furthermore, through holes are equidistantly arranged on the periphery of the guide sleeve, and the through holes are located at the bottom of the fastening hoop. The steel strands passing through the through holes are fixed again by the fastening hoop.

[0010] Furthermore, specifically, there are six groups of the anchor holes and the through holes, and the split collets form a conical barrel shape.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. For a multi-hole type anchor of the utility model, the steel strands to be fixed pass through the anchor holes and the through holes. The split collets are clamped on the outer side of the steel strands and are located within the anchor holes. The clamping plate is pressed downwards, and the locking bolts in the threaded holes are tightened respectively to quickly fix the clamping plate on the anchor plate.

[0013] 2. For a multi-hole type anchor of the utility model, the guide rod is sleeved in the guide sleeve to achieve quick positioning and high stability. The steel strands passing through the through holes are fixed again by the fastening hoop. Through the two - time anchoring of the steel strands, it is realized that the steel strands are not prone to slipping during the tensioning process and have high stability.

[0018] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0019] Such as Figures 1-3As shown in the figure, a porous anchor includes a through hole 11, a clamping plate 3, an anchor plate 6, and a guide rod 12. The top periphery of the anchor plate 6 is penetrated with anchor holes 9, and split collets 10 with a clamping function are arranged in the anchor holes 9. A plug-in groove 5 is formed in the top periphery of the anchor plate 6. The upper end of the anchor plate 6 is pressed with the clamping plate 3, and a plug-in ring 4 corresponding to the plug-in groove 5 is welded to the bottom periphery of the clamping plate 3. Tightening hoops 2 are equidistantly arranged on the top of the clamping plate 3. Threaded holes 8 are equidistantly arranged on the periphery of the anchor plate 6, and locking bolts 7 penetrate through the threaded holes 8.
