AI Technical Summary
In the existing technology, the installation method of the anchor for graphene non-removable insulation board is difficult to avoid the rear end of the anchor being located at the outer end of the insulation board, resulting in gaps after pouring.
A hole saw is used for pre-drilling. The combination of the hole saw rod and the slotted disc ensures that the rear chuck of the anchor is located inside the insulation board. The fast installation is achieved by connecting the output end of an electric pistol drill.
This enables rapid installation of anchors, avoids the back end of the anchor protruding on the outside of the insulation board, and ensures no gaps after pouring.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulation board installation technology, and more specifically, to a hole opener for anchors of graphene non-removable insulation boards. Background Technology
[0002] With the rapid development of composite wall insulation and the increasingly widespread application of integrated structural insulation systems, graphene formworkless insulation boards are gradually being put into use. Anchors are the most important components connecting the graphene formworkless insulation board to the structure. Currently, the anchor installation method for graphene formworkless insulation boards is to directly hammer the anchors. This method makes it difficult to install the rear end of the anchor, resulting in the rear end of the anchor being located at the outer end of the insulation board, leading to gaps between the anchor and the structure after pouring. Utility Model Content
[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a hole opener for anchors of graphene mold-free insulation boards, which can effectively improve the molding quality, facilitate the installation of anchors, and avoid gaps.
[0004] The present invention adopts the following technical solution:
[0005] A hole opener for anchors of graphene non-removable insulation boards includes a hole opener rod and a slotted disc. The middle of the slotted disc is connected to the hole opener rod. The front end of the hole opener rod is provided with external threads, and the slotted disc is provided with serrations. The rear end of the hole opener rod is connected to the output end of an electric pistol drill.
[0006] Furthermore, the distance between the front end of the slotted disc and the perforated rod is equal to the distance between the head of the anchor and the chuck at the rear end of the anchor.
[0007] Furthermore, the thickness of the slotted disc is equal to the thickness of the chuck at the rear end of the anchor.
[0008] Furthermore, the diameter of the perforated rod is 8mm.
[0009] Furthermore, the grooved disc has a thickness of 1.2 mm and a diameter of 18 mm.
[0010] Beneficial effects
[0011] This invention first drills holes in the insulation board and creates a slot for the chuck at the rear end of the anchor at the outermost part of the insulation board. When installing the anchor, it can be installed quickly without hammering. Moreover, the chuck at the rear end of the anchor will not be on the outside of the insulation board, so no gap will be generated after pouring. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of an embodiment of the present utility model;
[0013] Figure 2 This is a schematic diagram of an anchor component according to an embodiment of the present invention. Detailed Implementation
[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0015] As shown in the figure, this utility model discloses a hole opener for anchors in graphene non-removable insulation boards, including an opening rod 1 and a slotting disc 2. The middle of the slotting disc 2 is connected to the opening rod 1. The front end of the opening rod 1 is provided with an external thread 11, and the slotting disc 2 is provided with serrations 21. The rear end of the opening rod is connected to the output end of an electric pistol drill. The external thread 11 is used for slotting to facilitate the installation of the anchor 4. The slotting disc 2 slots the insulation board so that the anchor will not protrude from the insulation board after installation, thus preventing gaps during pouring.
[0016] In one embodiment of this utility model, the distance between the front ends of the slotted disc 2 and the perforated rod 1 is equal to the distance between the head of the anchor 4 and the chuck 5 at the rear end of the anchor. Depending on the specific building, the insulation board may be connected to the wall, the finishing layer, or the protective layer. Therefore, the sum of the lengths of the perforated rod 1 and the slotted disc 2 is greater than the thickness of the insulation board. One end of the perforated rod 1 has a hole in the wall, the finishing layer, or the protective layer, and due to the external thread, the hole has an internal thread.
[0017] In one embodiment of this utility model, the thickness of the slotted disc 2 is equal to the thickness of the chuck 5 at the rear end of the anchor. Thus, after the slotted disc 2 is slotted, the chuck 5 is positioned precisely within the chuck placement slot in the insulation layer.
[0018] In one embodiment of this utility model, the diameter of the perforated rod 1 is 8mm.
[0019] In one embodiment of this utility model, the thickness of the slotted disk 2 is 1.2 mm and the diameter of the slotted disk 2 is 18 mm.
[0020] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
