Description

Technical Field

[0001] This utility model relates to the technical field of rear anchoring mechanisms, specifically, to a rear anchoring mechanism between concrete and steel structures. Background Technology

[0002] The connection between steel structures and pre-cast concrete is referred to as post-anchoring technology. Currently, it mainly involves pre-embedding bolts in holes drilled in the concrete, connecting the steel structure to the external steel structure via bolts and connecting steel plates. Common types of bolts include expansion bolts, expanded-hole bolts, bonded anchors, chemical anchors, and concrete nails. Post-anchoring connections require drilling holes in the concrete, which can exert excessive pressure on the original concrete, leading to localized cracking, reduced concrete strength and load-bearing capacity, and adversely affecting the overall structural integrity. Due to the natural aging of anchors and environmental factors, steel reinforcement corrosion may occur, ultimately leading to steel reinforcement breakage and compromising the strength and stability of the concrete. Construction is difficult, and quality control is challenging. Improper construction and material selection can result in insufficient bonding between the anchors and the concrete, affecting the overall structural stability. Material quality is influenced by many factors, including substrate properties, anchor type, and construction environment. Improper construction can lead to poor anchoring results or even safety accidents. Therefore, we propose a post-anchoring mechanism between concrete and steel structures. Utility Model Content

[0021] Example 1

[0022] Please see Figures 1-2As shown, this embodiment provides a post-anchoring mechanism between concrete and steel structures, including a steel pad 1. Multiple chemical anchors 2 are disposed on one side of the steel pad 1, and a monitoring component 3 is disposed on one side of each chemical anchor 2. The monitoring component 3 includes a connecting block 31, which is threaded into the interior of the chemical anchor 2. The interior of the chemical anchor 2 has a groove that matches the connecting block 31. A monitor 32 is fixedly disposed at one end of the connecting block 31. To facilitate monitoring of the aging of the chemical agent, the monitor 32 employs pipe end-viewing technology and micro-deformation sensing technology. To prevent the monitor 32 from being scratched by the wall, the monitor 32 is disposed inside the chemical anchor 2. A knob 33 is provided at one end of the connecting block 31 near the monitor 32. The knob 33 is located on the outside of the chemical anchor 2. A locking block 34 is fixedly provided on the side of the knob 33 near the connecting block 31. A slot matching the locking block 34 is opened at one end of the connecting block 31. When using the device, the user first inserts one end of the locking block 34 into the slot at one end of the connecting block 31. Then, the user puts the connecting block 31 into the slot on one side of the chemical anchor 2 and tightens the connecting block 31 by turning the knob 33. At the same time, the monitor 32 gradually enters the inside of the slot on one side of the chemical anchor 2 along with the connecting block 31. Then, the user pulls out the knob 33.

[0023] Please see Figures 1-4As shown, one end of the chemical anchor 2 is slidably inserted into the middle of the steel pad 1. The steel pad 1 has multiple slots in the middle that match the chemical anchor 2. Multiple connecting angle steels 4 are provided on one side of the steel pad 1, with one side of each angle steel fitting against the steel pad 1. One end of the chemical anchor 2 is located on the side of the connecting angle steel 4 away from the steel pad 1. The connecting angle steel 4 has a slot in the middle that matches the chemical anchor 2. After the monitor 32 is installed, the user places the connecting angle steel 4 on one side of the steel pad 1, and then the user inserts the chemical anchor 2 through the connecting angle steel 4 and the steel pad. The steel pad 1 has a slot, and multiple sliders 6 are slidably arranged inside the steel pad 1. Each slider 6 is positioned on the upper side of a corresponding chemical anchor 2. A pressure spring 7 is fixedly installed on the upper side of each slider 6, and the pressure spring 7 is fixedly installed inside the steel pad 1. The steel pad 1 has a slot inside for limiting the slider 6. The upper side of the chemical anchor 2 has a slot that matches the slider 6. After the chemical anchor 2 is passed through the slot between the connecting angle steel 4 and the steel pad 1, the pressure spring 7 presses the slider 6 into the slot on the upper side of the chemical anchor 2, initially fixing the chemical anchor 2. A bolt 5 for fixing the chemical anchor 2 is threaded onto the side of steel 4 away from steel pad 1. The user fixes the chemical anchor 2 by tightening the bolt 5. A connecting anchor 8 is set between the two chemical anchors 2. The connecting anchor 8 is set on the side of steel pad 1 near the connecting angle steel 4. The connecting anchor 8 is telescopic and has a locking device fixed inside. A fixing block 9 for connecting the chemical anchor 2 to the connecting anchor 8 is fixed at one end. The two ends of the connecting anchor 8 are threadedly connected to the fixing blocks 9 at their upper and lower ends, respectively. After setting it up, the user connects the two ends of the connecting anchor 8 to the fixing blocks 9 at one end of the two chemical anchors 2, and locks the connecting anchor 8 by operating the locking device inside the connecting anchor 8. The chemical anchor 2 is filled with a chemical agent, which is a modified epoxy resin material. Several small holes are opened on one side of the chemical anchor 2. After the device is installed, the user inserts the ends of the multiple chemical anchors 2 away from the connecting angle steel 4 into the corresponding holes in the wall. Then the chemical agent inside the chemical anchor 2 flows out through the small holes on one side of the chemical anchor 2 and bonds the chemical anchor 2 to the wall.

[0024] In this embodiment, the post-anchoring mechanism between the concrete and steel structure is used by the user. First, the user inserts one end of the locking block 34 into the groove at one end of the connecting block 31. Then, the user places the connecting block 31 into the groove on one side of the chemical anchor 2 and tightens the connecting block 31. Next, the user passes the chemical anchor 2 through the connecting angle steel 4 and the steel pad 1 and fixes the chemical anchor 2 by tightening the bolt 5. Then, the user connects the connecting anchor 8 between the two fixing blocks 9 and locks it. Then, the user inserts the end of the chemical anchor 2 away from the connecting angle steel 4 into the hole in the wall. Then, the chemical agent inside the chemical anchor 2 flows out through the small hole on one side of the chemical anchor 2 and adheres the chemical anchor 2 to the wall. The assembly process of this device is simple and quick. After installation, the aging of the chemical agent can be monitored and the monitor 32 can be protected, saving the installation time of the device and improving the safety of the device.
