Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.

Examples

Referring to fig. 1, fig. 2, fig. 3, fig. 4, and fig. 5, an anchor bolt structure provided by an embodiment of the present invention is shown in fig. 1, fig. 2, and fig. 3, the anchor bolt structure includes a pre-buried pipe 1, and the pre-buried pipe 1 is used for being fixedly connected with a wall; the embedded pipe 1 comprises a threaded hole 2 formed along the axial direction of the embedded pipe;

and the outer side of the screw rod 3 is provided with an external thread matched with the threaded hole 2. The expansion phenomenon of traditional expansion screw can not appear after this pre-buried pipe of twist to this screw rod, can not produce the extrusion destruction to the wall body.

Furthermore, the embedded pipe 1 is fixedly connected with the wall body in a mode of punching and implanting the wall body and bonding and fixing the wall body by chemical bonding agents. The chemical bonding can adopt a chemical rubber tube used by a chemical bolt or any other chemical bonding agent capable of realizing the punching and fixing with a wall body. The embedded pipe is fixedly connected with the wall body in an embedded mode in the wall body building process. The embedded pipe can be arranged on the wall in advance in an embedded mode in the process of building the wall.

Further, a shockproof spring 4 is arranged in the threaded hole 2; the shockproof spring 4 is used for preventing the screw rod 3 from being separated under the action of vibration force when the screw rod 3 is positioned in the threaded hole 2. The shockproof spring is freely placed in the threaded hole, and the spring can generate certain outward supporting force for the screw rod after the screw rod is screwed in, so that the shockproof spring is prevented from being separated from the threaded hole under the action of vibration force.

Further, the threaded hole 2 is a blind hole formed along the axial direction of the embedded pipe. The blind hole can prevent the inside impurity that gets into of screw hole. The axis of the threaded hole 2 coincides with the axis of the embedded pipe. The outer side surface of the embedded pipe is provided with anti-skid threads 5. The arrangement of the protective thread 5 can ensure that the embedded pipe can be connected with a wall body more firmly.

Further, as shown in fig. 4 and 5, the screw rod fixing device further comprises a gasket 6, wherein the gasket 6 comprises a through hole for the screw rod to pass through; the gasket 6 is used for being placed at the screw rod inserting end of the embedded pipe. The screw rod is connected with a countersunk head, and a conical groove matched with the cone of the countersunk head is formed in one side, in contact with the countersunk head, of the gasket. The gasket is provided with a step structure, and the diameter of the conical groove is gradually reduced from the large diameter side to the small diameter side of the gasket; the diameter of the small-diameter side surface of the gasket is not smaller than the outer diameter of the embedded pipe. The gasket can further improve the waterproof performance and the anti-falling performance of the structure.

When the structure is used, firstly, a pre-embedded pipe can be drilled and implanted at the position where an anchor bolt is to be additionally arranged, the pre-embedded pipe is used as a permanent pre-embedded pipe with a closed bottom and fixed on the structure, and after the bar-planting glue or the peripheral structure is solidified, a screw is screwed into the pre-embedded pipe to fix a structural member to be fixed; in order to prevent the screw from being separated from the vibration, a vibration-proof spring is placed in the embedded pipe before the screw is installed.

In a word, the crab-bolt structure that this application provided, simple structure is reasonable, installation convenient to use. Compared with the expansion screw, the expansion screw has the advantages that the peripheral structure cannot be damaged due to outward expansion, and meanwhile, the waterproof performance is good. Compared with a chemical anchor bolt, the bolt can be replaced, and the waterproofness of the anchor bolt is further enhanced. Is worthy of large-area popularization and application.
