Abstract
Description
Technical Field
[0001] This utility model relates to the field of post-anchoring technology, specifically a post-anchoring device for building renovation projects. Background Technology
[0002] Post-anchoring, also known as anchoring in existing concrete structures using relevant technical means, is named in contrast to pre-anchoring (pre-embedding) during concrete pouring. It has advantages such as simple construction and flexible use. Anchor bolts are a general term for all post-anchoring components. They are classified into metal anchor bolts and non-metal anchor bolts according to different raw materials, and into expansion anchor bolts, hole-expanding anchor bolts, adhesive anchor bolts, concrete screws, shot nails, concrete nails, etc., according to different anchoring mechanisms. After a building is renovated or repaired, holes are drilled in the wall, adhesive is poured into the holes, and then the post-anchoring device is placed in the anchoring hole. When the adhesive is completely bonded to the post-anchoring device, the building is anchored.
[0003] After a building renovation project, the anchoring device needs to be stably placed in the anchoring hole to achieve the anchoring of the building. With long-term use, the anchoring device may loosen. A loose anchoring device will not provide good anchoring effect to the building wall and will also pose a certain danger. Therefore, an anchoring device for building renovation projects is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0023] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0024] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description.

[0027] Please see Figure 1-6 This utility model provides a technical solution:
[0028] An anchoring device for post-construction renovation includes a concrete screw 1, a wall 9, and an anchoring hole 10. A reinforcing plate 2 is provided at one end of the concrete screw 1. An installation hole 3 is provided on the inner side of the reinforcing plate 2. The reinforcing plate 2 is fixedly connected to the concrete screw 1 through the installation hole 3. A screw hole 4 of equal diameter is provided on the inner side of the reinforcing plate 2. A reinforcing bolt 5 is provided on the inner side of the screw hole 4 to connect the reinforcing plate 2 to the wall 9.
[0029] Anchor holes 10 are opened on the inner side of the wall 9, and concrete screws 1 are set on the inner side of the anchor holes 10. This arrangement enables the positioning of anchor holes 10, wall 9, and concrete screws 1. An annular protective shell 6 for placing rust inhibitor is sleeved on the outer side of the concrete screw 1. A through groove 7 is opened on the inner wall of the annular protective shell 6, and a sponge sleeve 8 is fixedly connected to the inner wall of the through groove 7. This arrangement allows the rust inhibitor to be absorbed by the sponge sleeve 8 installed through the through groove 7. The sponge sleeve 8, which absorbs the rust inhibitor, acts on the concrete screw 1, thereby making the concrete screw 1 adhere to the rust inhibitor. The sponge sleeve 8 is sleeved on the outer side of the concrete screw 1, and the sponge sleeve 8 fits against the concrete screw 1. This arrangement allows the sponge sleeve 8, which absorbs the rust inhibitor, to act on the concrete screw 1, thereby making the concrete screw 1 adhere to the rust inhibitor, thus preventing the concrete screw 1 from rusting to a certain extent. The screw holes 4 are evenly arranged, and the reinforcing plate 2 fits against the wall 9. This arrangement allows the reinforcing plate 2 to be connected to the wall 9 through the screw holes 4 and the reinforcing bolts 5.
[0030] Workflow: After drilling anchor holes 10 inside the wall 9, adhesive is poured into the anchor holes 10. The concrete screw 1 and the annular protective shell 6 are placed in the anchor holes 10 while rotating, so that the concrete screw 1 and the annular protective shell 6 can have as much contact with the adhesive as possible. Then, the reinforcing bolt 5 is placed in the screw hole 4 and driven into the wall 9 with the help of a tool, so that the reinforcing plate 2 reinforces the concrete screw 1. The reinforcing plate 2 is installed on the outside of the concrete screw 1 through the mounting hole 3, so that the concrete screw 1 can be stably placed in the anchor holes 10. When the adhesive and the anchoring device are completely bonded after the building renovation project, the building is anchored. Rust inhibitor is added to the inside of the shell of the annular protective shell 6. The rust inhibitor is absorbed by the sponge sleeve 8 installed through the through groove 7. The sponge sleeve 8 that absorbs the rust inhibitor will act on the concrete screw 1, so that the concrete screw 1 is covered with rust inhibitor, which can prevent the concrete screw 1 from rusting to a certain extent.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
