Problems solved by technology

If you want to take out the anchor bolts in the concrete and reuse them, unless the concrete is destroyed, it is self-evident that the labor intensity of destroying the concrete is large; moreover, it takes a lot of manpower and special equipment to reclaim several anchor bolts. , it is not cost-effective from a cost point of view
Therefore, the existing anchor bolts are discarded along with the concrete base after construction and application, and cannot be recycled and reused, making it a disposable consumable, which not only causes waste of resources, but also increases construction costs

Embodiment 1

[0029] Referring to Fig. 1: the present invention has bolt head 1 and bolt shank 5, and bolt shank 5 is spiral structure, and their pitches are equal, and the major diameter d, middle diameter d2 and minor diameter d3 between each imaginary circle that the screw thread of this helical structure forms are respectively Equal, that is to say that bolt rod 5 is consistent in diameter from its top to tail. It is equivalent to processing a steel bar of equal diameter into a helical structure with equal pitch, and the median diameters d2 between the imaginary circles formed by the threads of the helical structure are respectively equal. The bolt is similar to a wine corkscrew, it can withstand a large upward force after being tapped into the lid, and it can be easily unscrewed along the direction of its screw. The bolt head 1 is a threaded structure, which cooperates with the nut 2 (also can be a nut) and is used as a fixed object.

[0030] Its use includes the following steps: ①. P...

Embodiment 2

[0033] Referring to Fig. 2: the helical structure bolt rod 5 of the anchor bolt of the present invention is designed as a structure that the diameter from its top to the tail gradually decreases smoothly, that is, the median diameter between the imaginary circles formed by the helical structure bolt rod 5 threads d2 are respectively equal, the major diameter d between each imaginary circle gradually decreases smoothly from the top of the bolt 5 to the tail, and the minor diameter d3 between each imaginary circle gradually increases smoothly from the top to the tail of the bolt 5. It is equivalent to processing a tapered steel bar with a large upper end diameter, a smaller lower end diameter, and a smooth transition in the middle diameter successively into a helical structure, and the median diameters of the imaginary circles formed by the threads of the helical structure are respectively equal. In order to facilitate the recovery of anchor bolts, the pitches of the helical bolt...

Abstract

The invention discloses an easily reclaimed foundation bolt and a using method thereof. The foundation bolt is provided with a bolt head and a bolt rod, wherein the bolt rod has a spiral structure. The using method for the foundation bolt comprises the following steps: (1) preparing a casting material for a mounting base; (2) wrapping the bolt rod of the foundation bolt with a protective layer to prevent the cast mounting base from sticking the bolt rod; (3) casting the casting material in the step (1) to the mounting base, anchoring the bolt rod of the foundation bolt in the step (2) into the mounting base, and exposing the bolt head of the foundation bolt from the mounting base; (4) after the mounting base is solidified, performing construction application, fixing an object by using the bolt head of the foundation bolt exposed from the mounting base, and finishing construction; (5) grasping the part of the foundation bolt exposed from the mounting base by using a hand tool, rotating the hand tool in the direction accordant with the spiral direction of the foundation bolt, and reclaiming the foundation bolt; and (6) clearing the foundation bolt for subsequent construction. The easily reclaimed foundation bolt has the characteristics of convenient reclamation, repeated use, simple structure, easy machining, low cost and the like.

Description

Technical field: [0001] The invention belongs to the technical field of installation, and in particular relates to an easily recoverable anchor bolt for fixing objects and a method for using the easily recoverable anchor bolt. Background technique: [0002] Anchor bolts are used to fix large machinery and equipment or other fixed objects. One end of it is a ground anchor (that is, a bolt), which is fixed on a cast foundation (usually concrete), and the other end is a bolt head, which is a threaded structure. Nuts are used to fix machinery or other fixed objects. [0003] Due to the role of the anchor bolts, the anchor bolts must be firmly embedded in the concrete and cannot be loosened. Anchor bolts are usually designed in a hook shape, snake shape, inverted "T" shape, "herringbone" shape or "L" shape, etc. These structures can prevent the anchor bolts from loosening or pulling out from the concrete base. , Preset the anchor bolts in the mold, cast concrete, and the concre...
