Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction detection, in particular to a device for detecting the thickness of a protective layer of a thin-walled pier of a bridge. Background Art
[0002] With the rapid development of my country's economy, the number and speed of highway construction projects are also increasing. As an important component of highway construction, bridges have increasingly higher requirements for construction quality. According to the specifications, there are two key measurement items for the installation of thin-walled pier reinforcement: the thickness of the reinforcement cover and the spacing between the reinforcements. After the thin-walled pier formwork is installed, the thickness of the reinforcement cover is usually measured with a tape measure. Due to the high height of the thin-walled pier, the inspection requires the quality inspector to climb down the ladder to check the thickness of the cover, which makes the inspection inconvenient and time-consuming. Therefore, it is very necessary to find a simple and easy-to-use inspection device.
[0003] In the "Bridge Pier Column Steel Bar Protective Layer Thickness Detection Device" disclosed in publication number CN118603023A, the utility model includes a steel bar detector, a load-bearing frame, a rotating tray, and a translation slide. The translation slide is slidably connected to the load-bearing frame, and the rotating tray is rotationally connected to the translation slide. The steel bar detector is fixedly connected to the rotating tray and can detect the thickness of the steel bar protective layer; the crawling assembly is connected to the load-bearing frame and includes two clamping mechanisms, two traction racks, and two residual teeth. The two clamping mechanisms are symmetrically arranged on both sides of the load-bearing frame. The two traction racks are symmetrical and arranged close to the clamping mechanism on the right. The two traction racks are respectively fixedly connected to the load-bearing frame through tooth seats, and the two residual teeth are transmission-connected to the clamping mechanism on the right. The invention drives the steel bar detector through the crawling assembly, and this process does not require manual intervention by the operator. However, the device needs to be lifted onto the thin-walled pier by a crane. Each construction requires lifting once. The operating space on the thin-walled pier is limited, resulting in inconvenience in use and high safety risks. Utility Model Content
[0004] In order to overcome the above-mentioned defects in the prior art, a device for detecting the thickness of the protective layer of a thin-walled pier of a bridge is provided.
[0005] The technical solution of the present utility model is as follows: a device for detecting the thickness of the protective layer of the thin-walled pier of a bridge, comprising an adjusting support rod and a detection plate; the detection plate is assembled at one end of the adjusting support rod, and the detection plate is provided with a first detection edge and a second detection edge perpendicular to each other, the first detection edge is used to detect whether the protective layer of the thin-walled pier of the bridge exceeds the maximum thickness, and the second detection edge is used to detect whether the protective layer of the thin-walled pier of the bridge is less than the minimum thickness.
[0006] Preferably, the adjustable support rod includes at least two telescopic rod sections.
[0007] Preferably, the shape of the detection plate is a right-angled trapezoid; the length of the lower base of the right-angled trapezoid is the first detection side, and the height of the right-angled trapezoid is the second detection side.

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] A device for detecting the thickness of the protective layer of a thin-walled bridge pier. The detection plate is used to detect the maximum thickness and the minimum thickness of the protective layer of the thin-walled bridge pier through a first detection edge and a second detection edge respectively. Compared with traditional single detection methods, the thickness of the protective layer can be evaluated more comprehensively, thereby improving the accuracy and reliability of the detection. Since the detection plate has the function of detecting the maximum thickness and the minimum thickness at the same time, during the actual detection process, the detection task can be completed in one go without replacing the detection tool or adjusting the detection position. This greatly shortens the detection time and improves the detection efficiency. By adjusting the length of the support rod, the operator can easily reach the detection position, thereby improving the adaptability and flexibility of use of the detection device.
[0017] Furthermore, by adjusting the telescopic length of the rod, it can adapt to thin-walled bridge piers of different heights, thereby enhancing the versatility and flexibility of the detection device.
[0018] Furthermore, the right-angled trapezoidal shape design allows the detection plate to be easily inserted into the gap of the thin-walled pier of the bridge. At the same time, the first detection edge and the second detection edge can respectively adhere to the two sides of the protective layer, effectively detecting the maximum and minimum thickness of the protective layer.
[0019] Furthermore, the design of the fixing groove ensures a firm connection between the adjustment support rod and the detection plate, preventing shaking or falling off that may occur during the detection process, thereby improving the accuracy of the detection.
[0020] Furthermore, the fixing groove is opened at the center of the detection plate, so that the connection between the adjustment support rod and the detection plate is more balanced, which is conducive to maintaining the overall stability of the detection device.
[0021] Furthermore, the setting of the scale marks enables the inspectors to intuitively read the thickness value of the protective layer, thereby improving the accuracy and efficiency of the inspection.
[0022] Furthermore, the design of the connection structure enables the various sections of the adjustable support rod to be easily connected and disassembled, thereby facilitating transportation and storage.
[0023] Furthermore, the threaded connection has the advantages of simple structure, reliable connection, and easy disassembly, thereby ensuring a tight connection between the rod sections of the adjustment support rod.
[0024] Furthermore, the snap-fit connection has the advantages of being quick, convenient, and easy to operate, and can further improve the connection efficiency between the sections of the adjustable support rod.
[0025] Furthermore, the integrated structure design improves the overall strength and stability of the detection device, reduces detection errors caused by loose connections, simplifies the manufacturing process, and reduces production costs.

[0033] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.
[0034] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.
[0035] Example 1:
[0036] like Figures 1 to 3 As shown, this embodiment provides a device for detecting the thickness of the protective layer of a thin-walled bridge pier, the structure of which includes an adjustable support rod 1 and a detection plate 2. The adjustable support rod 1 is composed of at least two retractable rods, and the operator can adjust the overall length of the detection device according to actual needs. The detection plate 2 is in the shape of a right-angled trapezoid, with its lower base serving as the first detection edge 21, which is perpendicular to the high side of the right-angled trapezoid, namely the second detection edge 22. Precise scale marks are engraved on both the first detection edge 21 and the second detection edge 22 for directly reading the thickness of the protective layer.
[0037] The adjustment support rod 1 is vertically fixed to the side of the detection plate 2. The first detection edge 21 is used to detect whether the protective layer of the bridge thin-walled pier exceeds the maximum thickness, and the second detection edge 22 is used to detect whether the protective layer of the bridge thin-walled pier is less than the minimum thickness.
[0038] The adjustable support rod 1 is connected to the detection plate 2 via connecting structures at its ends. In this embodiment, the connecting structures utilize threaded connections, ensuring a secure and easily adjustable connection between the adjustable support rod 1 and the detection plate 2. A fixing slot 23, located in the center of the detection plate 2, secures the adjustable support rod 1 and ensures stability during testing.
[0039] In this embodiment, the adjustment support rod 1 and the detection plate 2 are welded together through the fixing groove 23, and the multiple rod bodies are detachably connected through the connection structure to facilitate carrying and storage.
[0040] Example 2:
[0041] like Figures 1 to 3As shown, this embodiment is similar to the first embodiment, but differs in the connection structure. In this embodiment, the connection structure at both ends of the adjustment support rod 1 uses a snap-fit connection instead of a threaded connection. The snap-fit connection makes the connection between the adjustment support rod 1 and the detection plate 2 faster and simpler, making it suitable for use in applications requiring frequent adjustments or rapid deployment.
[0042] In addition, the detection plate 2 in this embodiment is also a right-angled trapezoid, having a first detection edge 21 and a second detection edge 22, as well as scale markings. The adjustable support rod 1 is also composed of at least two retractable rod sections, allowing the user to adjust it according to the height of the thin-walled bridge pier.
[0043] Embodiment three:
[0044] like Figures 1 to 3 As shown, this embodiment provides a more compact device for measuring the thickness of the protective layer on thin-walled bridge piers. In this embodiment, the adjustable support rod 1 comprises multiple, retractable rod sections, providing a wider range of length adjustment. The detection plate 2 still utilizes a right-angled trapezoidal design, but the fixing slots 23 are positioned on the sides of the plate 2 rather than in the center to accommodate specific detection requirements.
[0045] The connection structure in this embodiment combines the advantages of threaded connection and snap-fit connection, that is, both a threaded interface and a snap-fit connection are provided at the connection part. Users can choose to use threaded connection or snap-fit connection according to actual conditions, which improves the flexibility and adaptability of the device.
[0046] Scale marks are provided on the first detection edge 21 and the second detection edge 22 to ensure the accuracy of the detection result. The device in this embodiment is particularly suitable for detecting the protective layer of thin-walled bridge piers with various heights and thickness requirements.
[0047] Detection method: Extend the detection device along the template into the thin-walled pier, the second detection edge 22 is close to the protective layer of the thin-walled pier of the bridge, and the detection plate 2 can be freely expanded and contracted, indicating that the minimum thickness of the protective layer meets the requirements, the first detection edge 21 is close to the protective layer of the thin-walled pier of the bridge, and the detection plate 2 can be freely expanded and contracted, indicating that the maximum thickness of the protective layer meets the requirements.
[0048] This detection device has a simple structure, is easy to use, and can detect quickly. When not in use, it can be placed on the operating platform, taking up little space and not affecting construction. Compared with other large-scale detection devices, it can avoid the safety risks caused by lifting up and down. This device is simple to manufacture and can be welded with discarded steel bars and iron plates, reducing waste of resources and lowering construction costs.
[0049] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
