Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anchor bolts, specifically a high-strength multi-point anchor bolt for transmission line projects. Background Technique
[0002] When a transmission line is under construction, it is necessary to fix a steel structure power tower to the ground using anchor bolts. Therefore, after the traditional anchor bolt fixes the steel structure power tower, when the steel structure power tower is subjected to an external force, the external force will be transferred to the anchor bolt and the concrete foundation. Since the surface area of the anchor bolt is small, the contact area during concrete pouring is small, making it difficult for the contact surface between the concrete foundation and the anchor bolt to bear a large external force, and the contact part between the concrete foundation and the anchor bolt is prone to being squeezed and cracked. In view of the above situation, technological innovation is carried out on the basis of the existing high-strength multi-point anchor bolts for transmission line projects. Content of the Utility Model
[0003] The purpose of the utility model is to provide a high-strength multi-point anchor bolt for transmission line projects to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A high-strength multi-point anchor bolt for transmission line projects, including:
[0005] An anchor bolt, on the outer side wall of which a reinforcement component is placed. The screw part of the anchor bolt is located on the top of the reinforcement component. The reinforcement component includes a support sleeve arranged on the outer side wall of the anchor bolt. Uniformly arranged limit rings are provided on the outer side wall of the support sleeve. Connecting columns are uniformly arranged in a circular array between every two groups of limit rings. Through holes are uniformly and vertically penetrated through the top of the limit rings in a circular array.
[0006] Preferably, the screw part of the anchor bolt is located on the top of the support sleeve. The anchor bolt and the support sleeve are made of the same material and are integrally formed.

[0008] Preferably, the connecting columns and the limit rings are made of the same material and the connection part is fixed by welding.
[0009] Preferably, each group of through holes is located between two connecting columns.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0011] In this utility model, the anchor bolts are cast into the foundation pit through concrete, and the reinforcement components are immersed in the concrete. Through the connecting columns, limiting rings and circulation holes, the anchor bolts can achieve multi-point contact with the inside of the concrete base, thereby increasing the contact surface between the two, so as to improve the connection strength between the anchor bolts and the concrete base, and further enable the anchor bolts and the concrete base to bear more external forces from the steel structure power tower.
