Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of anchor head assembly, especially a high strength anti -floating anchor head assembly. BACKGROUND

[0002] The configuration of the hook or mechanical anchoring at the end of the steel bar is an effective way to reduce the anchoring length, and the principle is to increase the anchoring bearing capacity by using the local extrusion of the anchor head (hook, anchor bar, anchor plate or bolt anchor head) at the end of the stressed steel bar on the concrete.

[0003] The existing technology with publication number CN220505076U usually adopts the nut anchor head and anchor plate in combination to strengthen the anchoring force, and then the nut anchor head is often reversed due to vibration transmission in actual application, which leads to poor anchoring force, low anchoring strength, and even the nut anchor head is cracked, which greatly affects the engineering safety.

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] Please see Figs. 1 to 3This application provides a high-strength anti-buoyancy anchor head assembly, including an anchor rod 1, a nut anchor head 2, an anchor plate 3, and a pressure plate 4. The nut anchor head 2 and the anchor plate 3 are both installed on the anchor rod 1. The nut anchor head 2 is spirally installed, and the anchor plate 3 can be welded or spirally installed. A housing 5 is installed on the anchor plate 3. The pressure plate 4 is slidably engaged in the housing 5. A turntable 6 is rotatably installed at the bottom of the pressure plate 4. A guide block 7 and a fixing block 8 are fixedly installed on the turntable 6. The guide block 7 and the fixing block 8 are spaced apart. A spring is fixedly installed on the fixing block 8. An abutment plate 10 is fixedly installed at the output end of the spring. The abutment plate 10 abuts against one side of the nut anchor head 2. A guide post 11 is fixedly installed on the guide block 7. A guide groove 12 is opened on the nut anchor head 2. The guide post 11 is slidably engaged in the guide groove 12.

[0020] In this embodiment, when the nut anchor head 2 vibrates, the several abutting plates 10 that abut it can buffer the vibration to a certain extent under the compression of the spring. Furthermore, since the swaying direction caused by the vibration of the nut anchor head 2 is unidirectional, the abutting plates 10 on the side of the swaying direction can generate friction, further reducing the swaying amplitude. Also, when the nut anchor head 2 vibrates, the large weight of the pressure plate 4 can cause it to slide downwards due to the vibration, thereby creating a downward sliding effect between the guide groove 12 on the nut anchor head 2 and the guide post on the guide block 7. Under the guidance of 11, the downward sliding tendency of the pressure plate 4 can be rotated into the tendency of the abutment plate 10 to drive the turntable 6 to rotate in a fixed direction, that is, to rotate in the tightening direction of the nut anchor head 2, thereby applying a pre-tightening force in the tightening direction to the nut anchor head 2 to prevent it from loosening. This pre-tightening force can be achieved by the rotational connection between the pressure plate 4 and the turntable 6. There is a certain gap between the guide block 7 and the nut anchor head 2 to prevent vibration from causing the guide block 7 to break. The outer shell 5 should be filled with cement, and the inner shell 5 is preferably sealed.

[0021] In some embodiments, to prevent the abutment plate 10 from deflecting, a telescopic rod 13 is fixedly installed on the fixing block 8. The output end of the telescopic rod 13 is fixedly connected to the abutment plate 10, and a spring is fixedly installed inside the telescopic rod 13 with its output end abutting against the output end of the telescopic rod 13. The telescopic rod 13 serves to fix the abutment plate 10, preventing it from deflecting, and also allows the top of the abutment plate 10 to abut against the turntable 6, further preventing the abutment plate 10 from deflecting.

[0022] In some embodiments, to facilitate the installation of the housing 5, grooves 14 are provided on both sides of the anchor plate 3. The housing 5 is divided into two symmetrical parts, and both housings 5 ​​are slidably engaged in the grooves 14. The two housings 5 ​​are connected by bolt assemblies 15. Thus, after the two symmetrically arranged housings 5 ​​are slidably engaged in the grooves 14, they are connected by bolt assemblies 15.

[0023] In some embodiments, to facilitate the rotation of the turntable 6 by the abutment plate 10, thereby tightening the nut anchor head 2, a plurality of universal balls 16 are rotatably installed on the turntable 6, and the universal balls 16 abut against the pressure plate 4.

[0024] In some embodiments, to further increase the downward pressure of the pressure plate 4, a counterweight 17 is fixedly installed on the pressure plate 4.

[0025] In some embodiments, in order to enable the housing 5 to slide within the slide groove 14, a slider 18 is fixedly installed at the bottom of the housing 5, and the slider 18 is slidably and sealingly installed within the slide groove 14.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
