Description

Technical Field

[0001] This utility model relates to the field of post-reinforcement of concrete, specifically a novel post-reinforcement device. Background Technology

[0002] Conventional post-embedded rebar installation often uses high-strength chemical anchoring, employing high-strength chemical anchoring adhesive to bond the bolts to the concrete, thereby achieving the pre-embedding effect. However, there are often steel components welded and fixed on the outside of the post-embedded parts. During the welding process, a large amount of heat is generated, with the molten pool temperature exceeding 1000℃. Since the post-embedded parts are connected to the anchoring, the heat is easily conducted to the chemical anchoring adhesive. Currently, the high-temperature resistance of anchoring adhesives on the market does not exceed 200℃, which cannot withstand the high-temperature welding environment. Welding will cause a significant reduction in the strength of the anchoring, posing a considerable safety risk.

[0003] If the reinforcing bars are installed first, the embedded parts are prefabricated and welded to the steel components to be fixed, and then fixed to the reinforcing bar rods with nuts, high temperature damage can be avoided. However, if the steel components are fixed at both ends, there will be a situation where the exposed threaded rod part of the rod will affect the installation. This method has installation limitations and cannot meet all working conditions.

[0004] If the embedded plate is prefabricated and welded to the steel component to be fixed before the rebar is installed, the rebar adhesive has no strength before it is cured, and temporary support is required for the steel component to be fixed, which is labor-intensive and time-consuming, and has significant drawbacks. Utility Model Content

[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a novel post-rebar installation device.

[0006] This utility model is implemented as follows: a novel rebar installation device is constructed, which includes an inner screw rod, an outer screw rod connected to the outer side of the inner screw rod by threads, the outer wall of the outer screw rod being filled with rebar installation adhesive, the rebar installation adhesive being filled inside the rebar installation hole, a steel component being provided at the lower right of the rebar installation hole, a nut being provided above the steel component, a washer being provided at the left end of the nut, a rear embedded part being provided at the left end of the washer, and concrete being provided at the left end of the rear embedded part.

[0008] Preferably, a steel component is soldered to the lower right end of the rear embedded part, and the rebar hole is located inside the concrete.

[0009] Preferably, the nut is used to fix the embedded part, and the embedded part is aligned with the rebar hole.

[0010] This utility model has the following advantages: This utility model provides a novel post-rebar installation device through improvements, which has the following improvements compared to similar equipment:

The inner screw is longer than the outer screw. During installation, the outer screw is first inserted into the drilled hole, and then the inner screw and nut are used to fix the rebar. Through structural optimization and process control, the device effectively avoids the impact of high-temperature welding on the rebar adhesive, ensuring structural reliability.

When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0017] Please see Figure 1 The present invention discloses a novel post-rebar anchoring device, comprising an inner screw rod 1, an outer screw rod 2 connected to the outer side of the inner screw rod 1 by threads, the outer wall of the outer screw rod 2 being filled with anchoring adhesive 3, the anchoring adhesive 3 being filled inside the anchoring hole 4, and the inner screw rod 1 being longer than the outer screw rod 2.

[0018] A steel component 5 is located to the lower right of the anchor hole 4, and a nut 6 is located above the steel component 5. The threaded structure of the nut 6, the inner screw 1, and the outer screw 2 facilitates the fixing of the embedded part 8.

[0019] The left end of the nut 6 is provided with a washer 7, the left end of the washer 7 is provided with a rear embedded part 8, and the left end of the rear embedded part 8 is provided with concrete 9.

[0020] The top of the outer screw 2 is closed, while the end of the inner screw 1 is square. The square shape of the inner screw 1 facilitates its installation.

[0021] The lower right end of the embedded part 8 is fixed with a steel component 5 by solder, and the rebar hole 4 is located inside the concrete 9.

[0022] Nut 6 is used to fix the embedded part 8, which is aligned with the rebar hole 4.

[0023] The working principle of a novel post-reinforcement rebar device based on the above embodiments is as follows:

[0024] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.

[0025] Second, the workers first drilled holes in the concrete 9 using an external impact drill to form rebar holes 4. The diameter of the drill holes should be 2mm larger than the diameter of the outer screw 2. After drilling, the workers used an external air compressor to clean the drill holes. They then used external absorbent cotton soaked in alcohol to clean the inner walls of the drill holes, ensuring they were clean. After the alcohol had evaporated and dried, they filled the drill holes with 2 / 3 of the volume of rebar adhesive 3. After protecting the outer opening of the outer screw 2, they inserted it into the drill holes, squeezing out any excess rebar adhesive 3. After pressing out, due to the closed setting of the outer screw 2, the anchoring adhesive 3 is difficult to enter the interior of the outer screw 2. Then, the workers weld and fix the rear embedded part 8 to the steel component 5 in the prefabrication plant. Then, the rear embedded part 8, which is welded to the steel component 5, is aligned with the right side of the anchoring hole 4. Then, the inner screw 1 is screwed into the outer screw 2 using an external wrench. Finally, the shim 7 and nut 6 are placed on the outside of the rear embedded part 8 respectively. The threaded structure of the nut 6, the inner screw 1, and the outer screw 2 is used to press the rear embedded part 8 tightly. Thus, through structural optimization and process control, the impact of high temperature welding on the anchoring hole 4 is effectively avoided, ensuring the reliability of the structure.

[0026] This utility model provides a novel post-rebar installation device by improving the design. The screw is divided into an inner screw 1 and an outer screw 2, which are then tightly connected by threads to prevent the rebar adhesive 3 from being injected into the device during rebar installation. The inner screw 1 is longer than the outer screw 2. During rebar installation, the outer screw 2 is first inserted into the drilled hole, and then the inner screw 1 and the nut 6 are used to fix the post-embedded part 8. Through structural optimization and process control, the impact of high-temperature welding on the rebar adhesive 3 is effectively avoided, ensuring structural reliability.
