Description

Technical Field

[0001] The utility model relates to the field of anchor bolts, in particular to a non-bonded inverted cone chemical anchor bolt. Background Art

[0002] The inverted cone chemical anchor is a gradually tapering inverted cone-shaped weld nail with a thicker bottom and a thinner top. The change in the shape of the inverted cone chemical anchor head can improve adhesion and better fix the building structure. The inverted cone chemical anchor is suitable for building materials of different thicknesses and can be used in different construction scenarios.

[0003] However, the existing inverted cone chemical anchor bolts still have the following problems during use:

[0004] The existing inverted cone chemical anchor is fixed to the concrete base material by epoxy resin anchor glue, so that the threaded rod on the inverted cone chemical anchor is exposed to the outside of the concrete base material, so that the connecting object and the inverted cone chemical anchor can be installed. Since the threaded rod of the inverted cone chemical anchor is easily contacted with the epoxy resin anchor glue during use, adhesion is generated between the epoxy resin anchor glue, the threaded rod and the concrete base material, which is not convenient for the subsequent disassembly of the inverted cone chemical anchor. Therefore, it is very necessary to involve a non-bonded inverted cone chemical anchor for use in the existing anchor field. Utility Model Content

[0005] In order to make up for the shortcomings of the prior art, the threaded rod of the existing inverted cone chemical anchor is easily exposed to the epoxy resin anchor glue during use, which causes adhesion between the epoxy resin anchor glue, the threaded rod and the concrete substrate, making it inconvenient to disassemble the inverted cone chemical anchor later. The utility model proposes a non-bonded inverted cone chemical anchor.

[0006] The utility model solves the technical problem by adopting the following technical solution: a non-bonded inverted cone chemical anchor bolt, comprising a cone chemical anchor bolt body, the cone chemical anchor bolt body is assembled on a concrete substrate, the cone chemical anchor bolt body further comprises an inverted cone rod and a threaded rod, the inverted cone rod is fixedly assembled on one end of the threaded rod, and anti-sticking material is applied on the inverted cone rod and the threaded rod, so that an anti-sticking layer is formed on the surface of the inverted cone rod and the threaded rod.

[0007] Preferably, the concrete substrate is provided with an assembly groove, and the assembly groove is equipped with epoxy resin anchoring glue.

[0008] Preferably, the inverted tapered rod and the threaded rod are plugged into the epoxy resin anchoring glue on the assembly groove.

[0009] The utility model is beneficial in that:

[0010] The utility model uses a drilling machine to drill a hole in a concrete base material so that an assembly groove is formed on the concrete base material, residues on the assembly groove are cleaned, epoxy resin rebar embedding glue is poured into the assembly groove, and the inverted tapered rod on the conical chemical anchor bolt body is inserted into the epoxy resin rebar embedding glue of the assembly groove, so that the inverted tapered rod and part of the threaded rod are located in the epoxy resin rebar embedding glue, and the epoxy resin rebar embedding glue is solidified in the assembly groove on the concrete base material, so that the conical chemical anchor bolt body cannot be pulled out from the epoxy resin rebar embedding glue on the assembly groove. In order to facilitate later replacement, anti-sticking material is applied to the threaded rod and the inverted tapered rod, so that the inverted tapered rod and the threaded rod cannot generate adhesion with the epoxy resin rebar embedding glue, and the conical chemical anchor bolt can still be disassembled on the epoxy resin rebar embedding glue by twisting the conical chemical anchor bolt.
