[0002] Crack width is an important indicator of structural damage, and measurement can be used to determine whether a structure poses a safety hazard. Based on the crack width measurement results, appropriate repair and reinforcement plans can be developed to ensure the safety and stability of the structure. Regular crack width measurement can monitor structural changes and promptly identify and address potential problems. A crack width gauge is a specialized instrument used to measure crack width in concrete structures such as houses, roads, and bridges.

This crack measuring instrument suitable for cracks of different widths is provided with a second connecting plate. When the distance between the measuring rods needs to be adjusted, the second connecting plate can be pulled to drive the second support plate to move, so that it can be detached from the measuring instrument body. After that, the measuring rod can be moved so that it can be close to the inner wall of the crack, thereby facilitating the measurement of the crack and making it convenient to use. When measuring crack width, it is sometimes necessary to measure crack depth to better evaluate the engineering situation, but the above devices cannot measure crack depth.

[0021] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0022] Example:

[0023] Reference Figures 1 to 4The present invention provides an instrument for measuring the width of cracks in engineering structures, comprising a stabilizing mechanism 1. A measuring plate 4 is fixedly connected to the upper side of the stabilizing mechanism 1. A fixed clamping block 2 is fixedly connected to the lower left rear end of the measuring plate 4. A depth gauge 3 is slidably connected to the lower front end of the measuring plate 4. The lower portion of the depth gauge 3 is substantially identical to the fixed clamping block 2. The stabilizing mechanism 1 maintains the measuring plate 4 in a horizontal position. The bottom of the fixed clamping block 2 is then aligned with one side of the crack. The depth gauge 3 is moved until it reaches the other crack edge. The crack width is then measured by observing the measuring plate 4. The depth gauge 3 can then be used to measure the crack depth.

[0024] The stabilizing mechanism 1 comprises a base 101, a sliding rod 102, a sliding cylinder 103, a fixing protrusion 104, a threaded hole 105, a fixing nut 106, a fixing block 107, and a blocking plate 108. The sliding cylinder 103 is fixedly connected to the left and right undersides of the measuring plate 4, and the blocking plate 108 is fixedly connected to the inner lower edge of the sliding cylinder 103. The fixing block 107 is slidably connected to the interior of the sliding cylinder 103, the sliding rod 102 is fixedly connected to the underside of the fixing block 107, the base 101 is fixedly connected to the underside of the sliding rod 102, the fixing protrusion 104 is fixedly connected to the left lower end of the sliding cylinder 103, the threaded hole 105 is provided inside the fixing protrusion 104, and the fixing nut 106 is threadedly connected to the threaded hole 105. During use, the fixing nut 106 is first rotated to allow the sliding rod 102 to slide. Then pull the sliding rod 102, and the fixed block 107 slides in the sliding cylinder 103 to keep the measuring plate 4 horizontal. Then rotate the fixing nut 106 to tighten the sliding rod 102. The blocking plate 108 and the fixed block 107 prevent the sliding rod 102 from escaping from the sliding cylinder 103.

[0025] The measuring plate 4 includes a mounting plate 401, a width scale 402, and a measuring slot 403. The mounting plate 401 is fixedly attached to the upper side of the slide cylinder 103. The width scale 402 is located in the upper center portion of the front side of the mounting plate 401, and the measuring slot 403 is located at the lower front end of the mounting plate 401. The measuring slot 403 allows the depth gauge 3 to slide, and the width scale 402 indicates the measured width. The mounting plate 401 secures the various mechanisms.

[0026] The depth gauge 3 includes a measuring rod fixing rod 301, a chute 302, a T-shaped slider 303, a first scale pointer 304, a measuring rod 305, a baffle 306, a depth scale 307, a second scale pointer 308, and a connecting slider 309. The connecting slider 309 is slidably connected within the measuring chute 403. The measuring rod fixing rod 301 is fixedly connected to the lower end of the connecting slider 309. The chute 302 is located on the left side of the measuring rod fixing rod 301. The T-shaped slider 303 is slidably connected within the chute 302. The second scale pointer 308 is fixedly connected to the front side of the measuring rod fixing rod 301. The measuring rod 305 is fixedly connected to the lower side of the T-shaped slider 303. The baffle 306 is fixedly connected to the lower side of the measuring rod 305. The first scale pointer 304 is fixedly connected to the bottom left side of the measuring rod fixing rod 301. The depth scale 307 is located on the left side of the measuring rod 305. The upper side of the second scale pointer 308 is located outside the width scale 402. The baffle 306 and T-shaped slider 303 prevent the measuring rod 305 from falling off. The second scale pointer 308 facilitates width observation. The connecting slider 309 allows the depth gauge 3 to slide within the measuring slot 403. To measure the depth, align the baffle 306 with the center of the crack and pull the measuring rod 305 downward until the baffle 306 touches the bottom, allowing the T-shaped slider 303 and measuring rod 305 to slide within the slot 302. The crack depth can then be observed using the first scale pointer 304.

[0027] Working principle: Before use, first rotate the fixing nut 106 to allow the sliding rod 102 to slide. Then pull the sliding rod 102, and the fixed block 107 slides in the sliding cylinder 103 to keep the measuring plate 4 horizontal. Then rotate the fixing nut 106 to tighten the sliding rod 102. When measuring the width, align the bottom of the fixed block 2 with one side of the crack, move the connecting slider 309 on the depth measuring device 3 in the measuring slot 403 until the baffle 306 reaches the edge of the crack on the other side, and finally use the second scale pointer 308 to assist in observing the width scale 402 on the measuring plate 4 to obtain the crack width. When measuring the depth, align the baffle 306 with the middle of the crack, pull the measuring rod 305 downward until the baffle 306 touches the bottom, so that the T-shaped slider 303 and the measuring rod 305 slide in the slot 302, and then observe the crack depth through the first scale pointer 304.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
