Abstract
Description
Technical Field
[0001] This application belongs to the technical field of health monitoring of concrete structures, and more specifically, relates to a multi-pole quick-mount frame for monitoring CCCW intelligent conductive coating. Background Technology
[0002] CCCW intelligent conductive coating is a multifunctional inorganic coating that combines traditional cement-based penetrating crystalline waterproofing material (CCCW) with conductive fillers. Structural health monitoring aims to assess the service status of building structures by collecting physical parameters from various sensors, and to provide a reference for structural maintenance decisions based on the results of structural health monitoring. CCCW-based intelligent conductive coatings show great potential in the field of bridge structural health monitoring due to their good compatibility with concrete substrates, low cost, and self-sensing capabilities.
[0003] The existing CCCW intelligent conductive coating structure health monitoring steps are as follows: apply a conductive coating to a designated area on the concrete surface at the bottom of the bridge; attach and fix the monitoring electrodes to the conductive coating for health monitoring.
[0004] Because bridges are prone to vibration due to vehicles or other factors, poor contact at the interface between the electrode and the conductive coating may cause changes in resistance, which in turn affects normal monitoring. Furthermore, if the electrode is damaged or needs to be replaced due to other factors, it is very easy to damage the conductive coating and affect the overall performance of the coating. Utility Model Content
[0005] The purpose of this application is to provide a multi-pole quick-mount bracket for monitoring CCCW intelligent conductive coatings, in order to solve the technical problems in the prior art where poor contact between the electrode and the conductive coating may cause resistance changes, thus affecting normal monitoring; and if the electrode is damaged or needs to be replaced due to other factors, it is easy to damage the conductive coating and affect the overall performance of the coating.
[0006] To achieve the above objectives, the technical solution adopted in this application is: to provide a multi-pole quick-mount bracket for monitoring CCCW intelligent conductive coatings, comprising: The mounting bracket is fixedly connected to the target concrete surface for monitoring. At least one mounting sleeve is disposed on the mounting bracket, one end of the mounting sleeve facing the conductive coating; and At least one set of electrode assemblies is installed one-to-one within the mounting sleeve; The electrode assembly includes: The outer casing is detachably connected to the mounting sleeve; An electrode post, slidably connected to the housing, and extending beyond the end of the mounting sleeve opposite the conductive coating; and An elastic element is disposed within the housing and connected to the electrode post; When the mounting bracket is fixed to the concrete, the elastic element applies a force toward the conductive coating to the electrode post, so that the protruding end of the electrode post abuts against the conductive coating.
[0007] In one possible implementation, based on the above technical solutions, the outer casing has an opening at one end opposite to the conductive coating; the electrode assembly further includes: A conductive screw is threadedly connected to the opening end of the housing; the conductive screw is electrically connected to the electrode post through the elastic element.
[0008] In one possible implementation, based on the above technical solutions, the elastic element includes: A copper compression spring is located inside the housing and connected between the electrode post and the conductive screw; wherein, when the mounting bracket is fixed to the concrete, the copper compression spring is in a compressed state.
[0009] In one possible implementation, in conjunction with the above technical solutions, the elastic element further includes: A conductive silicone contact is fixed to one end of the electrode post that protrudes from the mounting sleeve and is used to press against the conductive coating.
[0010] In one possible implementation, based on the above technical solutions, the end of the outer casing facing the conductive coating has a perforation; the electrode post includes: A sliding part, slidably connected to the through hole and extending out of the mounting sleeve; and A limiting part is located inside the outer shell and is fixed to the sliding part. The width of the limiting part is greater than the width of the through hole.
[0011] In one possible implementation, based on the above technical solutions, the end of the mounting sleeve facing away from the conductive coating is for the outer shell to be inserted; the outer circumferential surface of the outer shell is provided with a plurality of annular barbs along its axial direction, and the inner wall of the mounting sleeve is provided with a backstop structure that engages with the annular barbs; The anti-reverse structure is elastic, allowing the annular barb structure to disengage from it; the engaging force between the annular barb structure and the anti-reverse structure is greater than the elastic force of the elastic element.
[0012] In one possible implementation, based on the above technical solutions, the anti-reverse structure includes a plurality of annular elastic expansion pieces, each annular elastic expansion piece corresponding to and engaging with an annular barb structure; when the outer shell is inserted into the mounting sleeve, the annular elastic expansion piece is located on the side of the annular barb structure closest to the opening end of the outer shell. The outer shell opening is elastic, and the diameter of the conductive screw is larger than the diameter of the outer shell opening in its natural state, so that when the conductive screw is screwed into the outer shell opening, the engagement depth between the annular elastic expansion piece and the annular barb structure is increased.
[0013] In one possible implementation, based on the above technical solutions, the outer end of the outer shell near the conductive coating is tapered, and its outer diameter gradually decreases from away from to near the conductive coating.
[0014] In one possible implementation, based on the above technical solutions, the mounting bracket and the mounting sleeve are integrally formed.
[0015] In one possible implementation, based on the above technical solutions, the mounting bracket and the mounting sleeve are made of insulating plastic.
[0016] The beneficial effects of the multi-pole quick-mount bracket for CCCW intelligent conductive coating monitoring provided in this application are as follows: Compared with the prior art, the mounting bracket in this application is fixedly connected to the uncoated concrete without damaging the conductive coating. Moreover, the electrode assembly and the mounting sleeve are detachably connected. When the electrode is damaged, aged, or needs to be calibrated and replaced, the operation can be completed by disassembling the electrode assembly alone, without peeling off or touching the conductive coating, which helps to maintain the integrity of the coating structure and the stability of the conductivity.
[0017] The elastic element provides a continuous axial force towards the conductive coating for the electrode post. When the concrete structure vibrates due to factors such as vehicle traffic and environmental wind loads, the electrode post can adaptively compensate for displacement by sliding within the outer shell, maintaining constant contact with the conductive coating. This reduces resistance fluctuations caused by changes in contact gaps and improves the continuity and reliability of monitoring data. Simultaneously, the sliding design of the electrode post reduces the precision requirements for on-site installation, eliminating the need for precise control of the initial distance between the electrode post and the conductive coating, thus simplifying the construction process.

[0026] This application provides a description of a multi-pole quick-mount bracket for monitoring CCCW intelligent conductive coatings.
[0027] like Figure 1 and Figure 2 As shown, one embodiment of this application provides a multi-pole quick-mount frame for monitoring CCCW intelligent conductive coatings, including a mounting frame 1, at least one mounting sleeve 2, and at least one set of electrode assemblies 3. The mounting frame 1 is fixedly connected to the target monitoring concrete surface; at least one mounting sleeve 2 is disposed on the mounting frame 1, with one end of the mounting sleeve 2 facing the conductive coating; the electrode assemblies 3 are disposed one-to-one in the mounting sleeve 2.
[0028] The electrode assembly 3 includes a housing 31, an electrode post 32, and an elastic element 33. The housing 31 is detachably connected to the mounting sleeve 2; the electrode post 32 is slidably connected to the housing 31 and extends out of the mounting sleeve 2 at the end opposite the conductive coating; the elastic element 33 is disposed inside the housing 31 and connected to the electrode post 32.
[0029] When the mounting bracket 1 is fixed on the concrete, the elastic element 33 applies a force to the electrode post 32 toward the conductive coating so that the protruding end of the electrode post 32 is pressed against the conductive coating.
[0030] In this embodiment, the multi-pole quick-mount frame for monitoring the CCCW intelligent conductive coating is installed from bottom to top onto the concrete surface at the bottom of the bridge. The mounting frame 1 is used to fit the concrete surface and cover it with the conductive coating. The mounting frame 1 has monitoring ports that correspond one-to-one with the mounting sleeves 2, allowing the electrode posts 32 to pass through. The mounting frame 1 can be fixed to the uncoated concrete surface by expansion bolts or adhesive.
[0031] This embodiment provides a multi-pole quick-mount frame for monitoring CCCW intelligent conductive coatings. Compared with the prior art, firstly, the mounting frame 1 is fixedly connected to the uncoated concrete without damaging the conductive coating. Secondly, the electrode assembly 3 and the mounting sleeve 2 are detachably connected. When the electrode is damaged, aged, or needs to be calibrated and replaced, only the electrode assembly 3 needs to be disassembled to complete the operation. There is no need to peel off or touch the conductive coating, which helps to maintain the integrity of the coating structure and the stability of the conductivity.
[0032] The elastic element 33 provides a continuous axial force towards the conductive coating for the electrode post 32. When the concrete structure vibrates due to factors such as vehicle traffic and environmental wind loads, the electrode post 32 can adaptively compensate for displacement by sliding within the housing 31, always maintaining contact with the conductive coating. This reduces resistance fluctuations caused by changes in the contact gap and improves the continuity and reliability of monitoring data. Simultaneously, the sliding design of the electrode post 32 reduces the precision requirements for on-site installation, eliminating the need for precise control of the initial distance between the electrode post 32 and the conductive coating, thus simplifying the construction process.
[0033] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The outer casing 31 has an opening at one end away from the conductive coating; the electrode assembly 3 also includes a conductive screw 34, which is threaded to the open end of the outer casing 31; the conductive screw 34 is electrically connected to the electrode post 32 through an elastic element 33.
[0034] The structure employing a conductive screw 34 threadedly connected to the open end of the housing 31 serves a dual purpose of electrical conductivity and end sealing, simplifying the internal structure and assembly process of the electrode assembly 3. The threaded connection allows for convenient installation and removal without the need for special tools, facilitating future inspection and replacement of internal components. The elastic element 33 enables electrical connection between the electrode post 32 and the conductive screw 34, eliminating the need for internal wire welding, reducing internal wiring nodes, lowering the probability of loose connections and open circuits, and improving signal transmission stability.
[0035] The conductive screw 34 is located at the open end of the housing 31 away from the coating. External monitoring wires can be directly connected to the conductive screw 34. There is ample space for wiring operations, which facilitates wiring work for on-site construction personnel and improves on-site deployment efficiency. The threaded structure has a certain sealing performance, which can prevent external dust and moisture from entering the interior of the housing 31 to a certain extent, thus protecting internal components such as the elastic element 33 and electrode post 32 and extending the service life of the electrode assembly 3.
[0036] like Figure 2As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The elastic element 33 includes a copper compression spring 331, which is located inside the housing 31 and connected between the electrode post 32 and the conductive screw 34; wherein, when the mounting bracket 1 is fixed on the concrete, the copper compression spring 331 is in a compressed state.
[0037] A copper compression spring 331 is used as an integrated component combining elasticity and conductivity, simultaneously achieving both elastic clamping and electrical conduction functions. This eliminates the need for additional conductive wiring, simplifying the internal structure of the electrode assembly 3. Copper possesses excellent conductivity, resulting in minimal signal transmission loss and helping to ensure the accuracy of monitored electrical signals, thus improving data acquisition accuracy. After installation, the compression spring is in a compressed state, continuously outputting a stable and uniform axial thrust, ensuring consistent contact pressure between the electrode post 32 and the conductive coating, and maintaining stable elastic performance even under long-term, frequent vibration conditions.
[0038] A copper compression spring 331 is positioned between the electrode post 32 and the conductive screw 34. The force is directly transmitted along the axial direction of the electrode post 32, preventing lateral forces from interfering with the sliding of the electrode post 32 and ensuring smooth extension and retraction. The copper compression spring 331 is a common and mature component with low procurement and replacement costs. In the event of elastic fatigue during later maintenance, the spring component can be replaced separately without replacing the entire electrode assembly 3, thus helping to reduce maintenance costs.
[0039] like Figures 1 to 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The elastic element 33 also includes a conductive silicone contact 332, which is fixed to one end of the electrode post 32 that protrudes from the mounting sleeve 2 and is used to press against the conductive coating.
[0040] Conductive silicone combines good conductivity and flexibility, and can form surface contact with the conductive coating surface. Compared with the point contact or line contact of rigid electrodes, it can effectively increase the contact area, reduce contact resistance, and improve the accuracy of electrical signal acquisition.
[0041] The flexibility of conductive silicone allows it to adapt to minor unevenness on the conductive coating surface caused by the construction process. Even if the coating surface has a certain degree of roughness or local bumps, the contact can still maintain a tight fit with the coating. At the same time, the soft conductive silicone contact 332 can reduce mechanical wear on the conductive coating surface during the process of pressing against the coating and vibrating with the structure, thus reducing the impact on the coating's conductivity and waterproof performance.
[0042] like Figure 2As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The outer casing 31 has a through hole 311 at the end facing the conductive coating; the electrode post 32 includes a sliding part 321 and a limiting part 322. The sliding part 321 is slidably connected to the through hole 311 and extends out of the mounting sleeve 2; the limiting part 322 is located inside the outer casing 31 and is fixed to the sliding part 321. The width of the limiting part 322 is greater than the width of the through hole 311, and the outer peripheral surface of the limiting part 322 is in contact with the inner wall of the outer casing 31.
[0043] The perforation 311 at the end of the housing 31 and the sliding part 321 of the electrode post 32 provide precise guidance for the extension and retraction of the electrode post 32, which can limit the movement trajectory of the electrode post 32, prevent it from shifting laterally during vibration, and ensure that the electrode post 32 always presses against the conductive coating along the axial direction to maintain a stable contact state.
[0044] The limiting part 322 effectively constrains the sliding stroke of the electrode post 32, preventing it from detaching from the perforation 311 of the outer shell 31 under the continuous force of the elastic element 33, thus improving the overall reliability of the electrode assembly 3. Simultaneously, the close fit between the limiting part 322 and the inner wall of the outer shell 31 effectively prevents external dust, moisture, and other impurities from entering the interior of the outer shell 31 through the perforation 311, protecting the internal connecting wires and elastic element 33 from corrosion and extending the service life of the electrode assembly 3.
[0045] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The end of the mounting sleeve 2 facing away from the conductive coating is into which the outer shell 31 is inserted; the outer circumference of the outer shell 31 is provided with a plurality of annular barbs 312 along its axial direction, and the inner wall of the mounting sleeve 2 is provided with a backstop structure 21 that engages with the annular barbs 312.
[0046] The anti-retraction structure 21 is elastic, allowing the annular barb structure 312 to disengage from it; the snapping force between the annular barb structure 312 and the anti-retraction structure 21 is greater than the elastic force of the elastic element 33.
[0047] The annular barb structure 312 on the outer periphery of the outer shell 31 forms a snap-fit engagement with the anti-reverse structure 21 on the inner wall of the mounting sleeve 2. This eliminates the need for additional fasteners such as bolts and nuts, allowing for installation and removal of the electrode assembly 3 solely through insertion and removal operations, significantly improving the efficiency of on-site construction and subsequent maintenance. The anti-reverse structure 21 and the annular barb form an axial snap-fit limit, providing reliable holding force. The snap-fit force is greater than the elastic force of the elastic element 33, maintaining the fixed position of the outer shell 31 within the mounting sleeve 2 even when the elastic element 33 continuously applies a reverse thrust, reducing the risk of the outer shell 31 being pushed out by the elastic element 33.
[0048] The anti-retraction structure 21 is elastic, allowing the annular barbs to detach from it during disassembly using external force, achieving non-destructive assembly and disassembly and facilitating the reuse of the electrode assembly 3. Multiple sets of annular barbs and the anti-retraction structure 21 form a multi-point locking engagement, resulting in more even overall stress distribution. This prevents loosening under structural vibration and maintains long-term stability of the connection. The locking structure has relatively relaxed requirements on the machining precision of the inner wall of the mounting sleeve 2, accommodating certain manufacturing errors and helping to reduce the production cost of the quick-release frame.
[0049] like Figure 2 and Figure 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The anti-reverse structure 21 includes multiple annular elastic expansion pieces, which correspond one-to-one with the annular barb structure 312. When the outer shell 31 is inserted into the mounting sleeve 2, the annular elastic expansion piece is located on the side of the corresponding annular barb structure 312 near the opening end of the outer shell 31.
[0050] The outer shell 31 has an elastic opening end, and the diameter of the conductive screw 34 is larger than the diameter of the opening end of the outer shell 31 in its natural state, so that when the conductive screw 34 is screwed into the opening end of the outer shell 31, the engagement depth between the annular elastic expansion piece and the annular barb structure 312 is increased.
[0051] Multiple slots are also provided around the outer casing 31 to facilitate deformation of the outer casing 31 and save material.
[0052] The anti-loosening structure 21, which employs a one-to-one correspondence between annular elastic expansion pieces and annular barbs, increases the contact area of the snap-fit, improves the reliability of axial limiting, and can withstand greater axial forces. The annular elastic expansion pieces are arranged on the side of the corresponding annular barbs near the opening end of the outer shell 31. When the elastic element 33 pushes the outer shell 31 to tend to disengage outward, the snap-fit between the annular barbs and the elastic expansion pieces will be further tightened, providing an anti-loosening effect that increases with the force applied, making it more suitable for service scenarios with frequent vibrations, such as bridges.
[0053] The open end of the outer shell 31 is elastic. During the screwing in of the conductive screw 34, the open end of the outer shell 31 can be opened simultaneously, causing the annular elastic expansion piece to increase the engagement depth with the annular barb. This achieves connection reinforcement without additional tightening, simplifying the installation process while improving the connection's strength. When disassembling, unscrewing the conductive screw 34 allows the open end of the outer shell 31 to return to its original position due to its own elasticity, reducing the engagement depth between the annular elastic expansion piece and the annular barb, lowering the pull-out resistance, and facilitating the smooth removal of the electrode assembly 3. The disassembly and assembly logic is clear, and on-site operation is convenient.
[0054] like Figure 2As shown, this application provides another specific implementation method based on the above-described implementation method as follows: The outer end of the outer casing 31 near the conductive coating is tapered, and its outer diameter gradually decreases from away from to near the conductive coating.
[0055] The tapered design of the outer shell 31 near the conductive coating end provides good guidance during installation, making it easy for operators to quickly align the outer shell 31 and insert it into the installation sleeve 2, reducing the difficulty of alignment during on-site installation and improving installation efficiency.
[0056] like Figure 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: Mounting bracket 1 and mounting sleeve 2 are integrally formed.
[0057] The mounting bracket 1 and the mounting sleeve 2 adopt an integrated molding structure design, which can ensure the connection strength and dimensional accuracy between the two, avoid problems such as loosening, misalignment and deformation that may occur with separate connections, and improve the stability and reliability of the overall structure of the quick-mount bracket.
[0058] During the factory prefabrication stage, the number, spacing, and arrangement of the installation sleeves 2 can be flexibly adjusted according to the monitoring needs of different projects, producing multi-pole quick-assembly frames that are suitable for different monitoring scenarios. No secondary processing is required on the construction site, further simplifying the construction process.
[0059] like Figures 1 to 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows: Mounting bracket 1, mounting sleeve 2, outer shell 31, annular barb structure 312, and anti-reverse structure 21 are all made of insulating plastic. The outer shell 31 and annular barb structure 312 are integrally formed, as are the mounting sleeve 2 and anti-reverse structure 21.
[0060] The insulating plastic material has a certain degree of elasticity and can effectively block the conductive path between the electrode assembly 3 and the concrete structure, preventing the monitoring current from leaking through the mounting bracket 1 and mounting sleeve 2, eliminating stray current interference with the monitoring signal, and ensuring the accuracy of the monitoring data. The insulating plastic is lightweight, corrosion-resistant, and aging-resistant, making it suitable for complex outdoor service environments such as bridges and tunnels. Long-term use is not prone to rust, cracking, or other damage, extending the service life of the quick-mount bracket.
[0061] Insulating plastics have good processing performance, making it easy to use injection molding to achieve one-piece molding production. It can efficiently process complex structural shapes and has low production costs. It is easy to integrate the mounting bracket 1 and mounting sleeve 2, the outer shell 31 and the annular barb structure 312, and the mounting sleeve 2 and the anti-reverse structure 21.
[0062] The above are merely preferred embodiments of this application and are not intended to limit this application.
