Description

Technical Field

[0001] This utility model relates to the field of anchor bolt technology, specifically a powerful anchor bolt. Background Technology

[0002] An anchor is a mechanical or chemical fastener used to secure structures or equipment. It permanently fixes the threaded portion to a substrate such as concrete or masonry through mechanical expansion or chemical bonding, with only the nut being removable. Its core function is to provide resistance to tensile and shear forces, ensuring the stability of the connection.

[0003] Patent document CN210395339U discloses a finned high-strength anchor bolt. "Its anchor bolt body is a solid rod, with a tray and a fastening nut at the rear end. A set of axial grooves and a blocking sleeve are provided at regular intervals on the inner section of the solid rod. Each axial groove is movably connected to a rearward-extending fin, which rests on the front end of the blocking sleeve. When the solid rod is pulled outward from the hole under the action of the fastening nut and the blocking sleeve remains stationary, the fins are pushed outward by the blocking sleeve and supported on the hole wall. Because the impedance is achieved using fins, the fin cross-sectional area is large, the bearing capacity is high, and the structure is simple." However, this finned bolt structure is relatively complex, resulting in high anchor bolt usage costs and a lack of promising development prospects.

[0004] Therefore, a high-strength anchor bolt is now being developed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a powerful anchor bolt to solve the technical problem mentioned in the background art, which is that the structure of the finned bolt is relatively complex, resulting in high cost of use and poor development prospects.

[0006] The technical solution of this utility model is implemented as follows: A powerful anchor bolt includes an anchor bolt sleeve, an anchor bolt thread is installed inside the anchor bolt sleeve, a tensioning head is installed at one end of the anchor bolt thread, an installation head is installed at one end of the tensioning head, and an elastic fastening component is installed at one end of the installation head. The elastic fastening component is used to improve the firmness of the anchor bolt. The elastic fastening component includes an installation groove, a connecting spring, and a connecting disc. The installation groove is formed at one end of the installation head, one end of the connecting spring is installed inside the installation groove, and the other end of the connecting spring extends out of the installation groove. The connecting disc is installed at one end of the connecting spring.

[0007] Preferably, the outer side of the anchor sleeve is symmetrically provided with through holes, and a dividing groove is provided through one side of the through holes. The dividing groove penetrates the interior of the anchor sleeve and extends to one end of the anchor sleeve.

[0008] Preferably, a positioning nut is threaded onto the outer side of the other end of the anchor bolt, and the positioning nut is located on one side of the anchor bolt sleeve.

[0009] Preferably, a fixing washer is fitted on the outer side of the anchor bolt, and the fixing washer is located on one side of the positioning nut.

[0010] Preferably, the outer side of the anchor bolt is fitted with an elastic pad, and the elastic pad is located on one side of the fixing pad.

[0011] The present invention has the following advantages due to the adoption of the above technical solution:

[0012] 1. The anchor bolt structure in this utility model is simple, but it is more secure after installation. The installation head provides a position for the installation of the elastic fastening component. When the anchor bolt is installed into the preset hole groove, the connecting plate in the elastic fastening component contacts the inner wall of one end of the preset hole groove. After the installation is completed, the connecting spring is compressed to generate a reverse elastic force, making the anchor bolt installed in the preset hole groove more secure and improving the strength of the anchor bolt.

[0013] 2. In this utility model, when the anchor bolt sleeve and the anchor bolt screw are inserted into the preset hole groove, the tensioning head moves towards the opening and dividing end of the anchor bolt sleeve by the rotation of the anchor bolt screw. Since the tensioning head is trapezoidal, when the tensioning head moves to the dividing end of the anchor bolt sleeve, it opens the dividing end of the anchor bolt sleeve, thereby making the anchor bolt more stable in the preset hole groove.
