Description

Technical Field

[0001] This utility model relates to the field of segment data status monitoring devices, and specifically refers to an embedded concrete segment data status monitoring device. Background Technology

[0002] With the continuous increase in engineering construction, especially in the development of commercial and civil buildings, bridges, underground rail transit, water conservancy pipelines, underground integrated pipe corridors, and undersea tunnels, concrete structures, as building structural components, serve as a safety barrier for engineering projects. While the number of concrete structures is increasing, monitoring their health status remains a significant challenge. Currently, health status is largely determined through manual inspections or by examining their appearance using video equipment, which offers limited effectiveness.

[0003] The prior art 201922247724.7 discloses an embedded concrete structure health status monitoring device. Although it solves the above problems, it is only fixed by clips. During the pouring and vibration of cement, the clips may come loose, causing problems with the detection. Furthermore, if the spacing between the reinforcing bars fluctuates, the clips cannot be fastened, resulting in low adaptability. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by providing an embedded concrete segment data status monitoring device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an embedded concrete segment data status monitoring device, comprising a shell, a cover plate disposed on the top surface of the shell, strain gauges disposed in the middle of the shell and extending out of the shell at both ends, two claws disposed at both ends of the bottom surface of the shell, two sets of anti-detachment components disposed on the two claws to prevent disengagement, a translation component disposed at one end of the bottom surface of the shell for fine-tuning the spacing of one set of clipping components, and four support feet disposed on both sides of the bottom surface of the shell along the length direction and located between the claws for support.

[0006] Preferably, the anti-detachment component includes two rectangular clearance grooves that are respectively disposed through both sides of the clamp and extend to the middle of both sides of the clamp, while the other end separates the bottom clamps of the clamp; and two anti-detachment claws that are rotatably disposed at one end in the two rectangular clearance grooves and extend out of the other end, with the openings of the two rectangular clearance grooves fitting together to close the gap between the bottom clamps of the clamp; when the two anti-detachment claws are flipped toward both sides of the clamp, the end located in the middle of both sides of the clamp rotates toward the clamp.

[0007] Preferably, the anti-drop component includes a first Velcro with fine, soft, round fibers fixed at one end to the lower side of one side of the claw, and a second Velcro with harder, hooked burrs disposed at the lower side of the other side of the claw for attaching the other end of the first Velcro.

[0008] Preferably, the inner wall of the claw is provided with a rubber pad to increase friction.

[0009] Preferably, the translation component includes a dovetail-shaped groove disposed at one end of the bottom surface of the housing and placed along the length of the housing, and a slider slidably disposed in the groove.

[0010] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0011] This invention, by setting a snap-fit ​​component to prevent disengagement, can effectively avoid the phenomenon of disengagement during the vibration of poured concrete segments, improve the accuracy of test data, and by using a translation component, can avoid the problem of the snap-fit ​​not being able to be finely adjusted when the spacing between the reinforcing bars becomes larger or smaller, thus improving adaptability.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Appendix Figure 1-6 The embedded concrete segment data status monitoring device of this utility model includes a shell, a cover plate 2 on the top surface of the shell, strain gauges 3 located in the middle of the shell and extending out of the shell at both ends, two claws 4 located at both ends of the bottom surface of the shell, two sets of anti-detachment components 5 located on the two claws 4 to prevent disengagement, a translation component 6 located at one end of the bottom surface of the shell for fine-tuning the spacing of one set of clipping components, and four support feet 7 located on both sides of the bottom surface of the shell along the length direction and between the claws 4 for support; the translation component 6 includes a dovetail-shaped groove 61 located at one end of the bottom surface of the shell and placed along the length direction of the shell, and a slider 62 slidably located in the groove 61.

[0022] In embodiment 1, the anti-detachment component 5 includes two rectangular clearance grooves 51a that are respectively disposed through both sides of the clamping jaw 4, with one end extending to the middle of both sides of the clamping jaw 4 and the other end separating the bottom clamps of the clamping jaw 4; and two anti-detachment claws 52a, one end of which is rotatably disposed within the two rectangular clearance grooves 51a and the other end extending out of the two rectangular clearance grooves 51a. The openings of the two rectangular clearance grooves 51a fit together to close the gap between the bottom clamps of the clamping jaw 4. When the two anti-detachment claws 52a are flipped toward both sides of the clamping jaw 4, the end located in the middle of both sides of the clamping jaw 4 rotates toward the clamping jaw 4. During installation, firstly, according to the spacing between the reinforcing bars... The sliding slider 62 adjusts the position of one of the claws 4, causing the bottom ends of the two anti-detachment claws 52a to flip towards the sides of the claw 4, while the top ends of the anti-detachment claws 52a flip inwards towards the claw 4. The claw 4 then latches onto the rebar. As the rebar is latched, it pushes the top ends of the two anti-detachment claws 52a to flip towards the sides of the claw 4, and the bottom ends of the two anti-detachment claws 4 flip towards the rebar. When the claw 4 is fully latched onto the rebar, the bottom ends of the two anti-detachment claws 4 are just flipped to the bottom of the rebar and fit together. Because the rebar will prevent the anti-detachment claws from falling off, the anti-detachment claws 4 will be fully latched onto the rebar. The flipping direction of the top and bottom of the release claw 4 is limited, so the reinforcing bar is wrapped inside the claw 4, effectively preventing the possibility of disengagement during vibration. The shell is located at the bottom of the segment mold, ensuring that the four supporting feet 7 of the shell can contact the bottom of the mold to provide support. The shell is installed after the reinforcing bar cage, and data is read and written and bound using a handheld PDA. The data is then stored in the database and permanently bound and associated with the corresponding reinforcing bar cage and the corresponding segment produced. The shell has built-in temperature, humidity, and gas sensors, a PDA antenna, and a data acquisition chip for collecting data on the temperature inside the segment. Humidity and gas parameters are collected by strain gauge 3, which is used to collect strain and deformation data of the tube segment. Temperature, humidity, gas, strain and deformation data are collected by the data acquisition chip inside the shell and wirelessly transmitted to the inspection instrument via radio frequency antenna. Since the temperature, humidity, gas sensors, PDA antenna and data acquisition chip are existing technologies of existing patent 201922247724.7, they are not described in detail. The content of this patent is to improve the buckle structure in existing patent 201922247724.7 so that it can adapt to different spacing and prevent disengagement.

[0023] In embodiment two, the anti-detachment component 5 includes a first Velcro 51b with fine, soft fibrous round bristles fixed to one side of the claw 4, and a second Velcro 52b with harder, hooked burrs attached to the other side of the claw 4. During installation, firstly, slide the slider 62 according to the spacing between the reinforcing bars. The slider 62 causes one of the claws 4 to adjust its position slightly. Then, the claw 4 is snapped onto the reinforcing bar. Next, pull one end of the first Velcro 51b through the bottom of the reinforcing bar and through the second Velcro 52b attached to the other side of the claw 4. The first Velcro 51b and the claw 4 then work together to wrap around the reinforcing bar, effectively preventing detachment during vibration. The housing is located at the bottom of the segment mold, ensuring that the four supporting feet 7 of the housing can contact the bottom of the mold for support. The housing is installed on the reinforcing bar skeleton. Afterwards, a handheld PDA is used for data reading and writing binding, and the data is stored in the database, permanently bound and associated with the corresponding steel reinforcement frame and the corresponding pipe segments produced. The housing contains temperature, humidity, and gas sensors, a PDA antenna, and a data acquisition chip, used to collect temperature, humidity, and gas parameters inside the pipe segments. Strain gauge 3 is used to collect strain and deformation data of the pipe segments. The temperature, humidity, gas, strain, and deformation data are collected by the data acquisition chip inside the housing and wirelessly transmitted to the inspection instrument via the radio frequency antenna. Since the temperature, humidity, and gas sensors, PDA antenna, and data acquisition chip are existing technologies of existing patent 201922247724.7, they are not described in detail. However, the content of this patent is an improvement on the buckle structure in existing patent 201922247724.7, which can adapt to different spacings and prevent disengagement.

[0024] Furthermore, the inner wall of the claw 4 is provided with a rubber pad 8 to increase friction and prevent left and right displacement.

[0025] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
