Description

Technical Field

[0001] This utility model relates to the field of steel reinforcement protective layer thickness detection technology, and in particular to a steel reinforcement protective layer thickness detection device for engineering construction supervision. Background Technology

[0002] In reinforced concrete structures of building engineering, when steel bars are exposed to the atmosphere or other media, they are easily corroded and rusted, which reduces the effective cross-section of the steel bars and affects the structural stress. Therefore, it is necessary to specify the thickness of the concrete cover for different service environments according to durability requirements to ensure that the steel bars do not corrode and reduce the reliability of the structure within the design service life of the component.

[0003] In the process of inspecting the concrete cover of reinforcing bars, a concrete cover measuring instrument is usually used to determine the thickness of the concrete cover, the location of the reinforcing bars, and the arrangement of the reinforcing bars. During use, the operator holds the measuring instrument and moves it linearly along the inspection area to complete the scanning process. However, errors can easily occur during linear movement, thus affecting the measurement results.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a steel reinforcement protective layer thickness detection device for engineering construction supervision, which aims to solve the technical problem that the steel reinforcement protective layer measuring instrument is prone to producing errors when making linear motion in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for detecting the thickness of the concrete cover of reinforcing bars for engineering construction supervision includes two symmetrically arranged supports, two guide rods disposed between the two supports, a slide block slidably disposed on the two guide rods, and a mounting frame for fixing the concrete cover measuring instrument. A pressing component is provided between the slide block and the mounting frame. The mounting frame has a U-shaped structure. The pressing component includes a first sliding column fixed on the mounting frame and a first spring sleeved on the first sliding column. The first sliding column is slidably connected to the slide block. The two ends of the first spring abut against the slide block and the mounting frame, respectively. A stop block is provided at the end of the first sliding column.

[0008] Furthermore, the slide includes four sliding sleeves, with two sliding sleeves installed on a guide rod. Each sliding sleeve is provided with a horizontal plate, which is connected to the mounting bracket via a pressing assembly.

[0009] Furthermore, the mounting frame includes a U-shaped frame and two fixing strips that are slidably connected to the inner side of the U-shaped frame. The two fixing strips are installed on both sides of the rebar cover measuring instrument.

[0010] Furthermore, the guide rod includes several connectable intermediate sections, as well as a connecting section for connecting the intermediate sections to the bracket.

[0011] Furthermore, splicing components are provided between two adjacent intermediate sections and between the intermediate section and the connecting section. The splicing components include male and female fasteners that cooperate with each other. The male fastener includes a short post and two first lugs symmetrically located at the ends of the short post. The female fastener includes two symmetrically located arc-shaped baffles. A second lug is provided at the top of the arc-shaped baffles. When the first lugs are inserted into the second lugs and the arc-shaped baffles, the male and female fasteners are engaged.

[0012] Furthermore, the bracket has through holes that match the connecting section and a clamping assembly located above the through holes. The clamping assembly includes a fixing plate, a vertically sliding positioning block, and a second spring for connecting the fixing plate and the positioning block. The connecting section has a slot for inserting the positioning block.

[0013] Furthermore, the positioning block is provided with a handle that extends horizontally.

[0014] Furthermore, the bracket includes an L-shaped frame and two height-adjusting feet located at the bottom of the L-shaped frame. Each height-adjusting foot includes a base plate, on which a vertical rod and a height-adjusting screw are slidably connected to the L-shaped frame. The height-adjusting screw has two positioning nuts.

[0015] Beneficial effects: (1) Under the guiding action of the guide rod and the pressing action of the pressing component, the rebar cover measuring instrument always stays close to the detection surface and moves along the predetermined route during the measurement process, avoiding errors; (2) The guide rod is set as a splicing structure, and the guide rod can be assembled according to the actual measurement distance, improving the applicability range; (3) The guide rod and the bracket can be quickly assembled and disassembled by the clamping component, improving the convenience of use.

Detailed Implementation

[0024] This utility model provides a device for detecting the thickness of the protective layer of reinforcing steel bars for engineering construction supervision. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following detailed description, with reference to the accompanying drawings and embodiments, further illustrates the utility model. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0025] Please see Figures 1 to 5 As shown, this utility model provides a steel reinforcement protective layer thickness detection device for engineering construction supervision, including two symmetrically arranged supports 1, two guide rods 2 arranged between the two supports 1, a slide block 3 slidably arranged on the two guide rods 2, and a mounting frame 4 for fixing the steel reinforcement protective layer measuring instrument. A pressing component 5 is provided between the slide block 3 and the mounting frame 4. The mounting frame 4 has a U-shaped structure. The pressing component 5 includes a first sliding column 51 fixed on the mounting frame 4 and a first spring 52 sleeved on the first sliding column 51. The first sliding column 51 is slidably connected to the slide block 3. The two ends of the first spring 52 abut against the slide block 3 and the mounting frame 4 respectively. A stop block 53 is provided at the end of the first sliding column 51.

[0026] In use, the rebar cover tester is fixed inside the mounting frame 4, allowing the operator to hold the tester and perform the corresponding operations. During measurement, the first spring 52 remains extended due to its elasticity, pressing the mounting frame 4 against the position to be tested, ensuring the rebar cover tester remains in contact with the test surface. The operator holds the handle of the rebar cover tester and moves it horizontally. Guided by the guide rod 2, the direction of movement of the rebar cover tester is limited. Compared with existing technologies, this ensures that the rebar cover tester moves in close contact with the test surface throughout the measurement process and that it moves along a predetermined path, avoiding errors and thus ensuring the accuracy of the measurement results.

[0027] In a preferred embodiment, see [reference] Figure 2 , 3 The slide block 3 includes four sliding sleeves 31, with two sliding sleeves 31 corresponding to each guide rod 2. Each sliding sleeve 31 is provided with a horizontal plate 32, which is connected to the mounting frame 4 via a pressing component 5. By independently setting the four sliding sleeves 31, even if the two guide rods 2 are not on the same plane due to unevenness of the detection surface, the sliding sleeves 31 can still move along their corresponding guide rods 2 without affecting each other. Furthermore, under the action of the pressing component 5, the corresponding position on the mounting frame 4 can be pressed against the detection surface, thereby ensuring that the wheel surface of the rebar cover measuring instrument is in close contact with the detection surface.

[0028] In the above embodiments, each pressing component 5 has two first sliding pillars 51 to improve the effect of the pressing mounting bracket 4.

[0029] In a preferred embodiment, see [reference] Figure 3 The mounting frame 4 includes a U-shaped frame 41 and two fixing strips 42 that are slidably connected to the inner side of the U-shaped frame 41. The two fixing strips 42 are installed on both sides of the rebar cover measuring instrument. Specifically, the fixing strips 42 are provided with T-shaped slide bars 421. The inner side of the U-shaped frame 41 has a slide groove 411 that is slidably connected to the T-shaped slide bar 421. The T-shaped slide bar 421 moves along the slide groove 411 and is locked in place by screws, thereby adjusting the relative position between the rebar cover measuring instrument and the U-shaped frame 41, and thus fine-tuning the front and rear position of the rebar cover measuring instrument.

[0030] In a preferred embodiment, see [reference] Figure 1 The guide rod 2 includes several connectable intermediate sections 21 and connecting sections 22 for connecting the intermediate sections 21 to the bracket 1. In actual use, the guide rod 2 can be assembled according to the detection length. After the intermediate sections 21 are assembled, connecting sections 22 are installed at both ends. The two connecting sections 22 are fixed on the two brackets 1 respectively to realize the installation of the guide rod 2.

[0031] Further, see Figure 6 , 7 A splicing assembly is provided between two adjacent intermediate sections 21 and between an intermediate section 21 and a connecting section 22. By setting the splicing assembly, quick assembly and disassembly between the two intermediate sections 21 and between the intermediate section 21 and the connecting section 22 can be achieved, improving ease of use. The splicing assembly includes a male buckle 23 and a female buckle 24 that cooperate with each other. The male buckle 23 includes a short post 231 and two first latches 232 symmetrically located at the ends of the short post 231. The female buckle 24 includes two symmetrically arranged arc-shaped baffles 241. A second latch 242 is provided at the top of the arc-shaped baffles 241. When the first latch 232 is inserted into the second latch 242 and the arc-shaped baffles 241, the male buckle 23 and the female buckle 24 are engaged. In the engaged connection state, the first latch 232 is located within the cavity 243 formed by the arc-shaped baffles 241 and the second latch 242. During connection, the short post 231 is inserted along the gap between the two arc-shaped retaining edges 241, and then rotated 90° so that the first locking lug 232 engages with the cavity 243, at which point the male buckle 23 and the female buckle 24 are engaged. During disassembly, the operator rotates the intermediate section 21 or the connecting section 22 90°, causing the male buckle 23 and the female buckle 24 to rotate relative to each other by 90°, moving the first locking lug 232 away from the cavity 243. Then, the short post 231 can be pulled out along the gap between the two arc-shaped retaining edges 241. Through the mutually matching male buckle 23 and female buckle 24, quick installation or removal of the two intermediate sections 21, and between the intermediate section 21 and the connecting section 22, is achieved.

[0032] In this embodiment, see Figure 4 , 5 The bracket 1 has a through hole 13 that matches the connecting section 22, and a clamping assembly 6 located above the through hole 13. The clamping assembly 6 includes a fixing plate 61, a vertically sliding positioning block 62, and a second spring 63 for connecting the fixing plate 61 and the positioning block 62. The connecting section 22 has a slot 221 for inserting the positioning block 62. During installation, the positioning block 62 is pulled towards the fixing plate 61, avoiding the position of the through hole 13. The second spring 63 retracts, and the connecting section 22 is inserted into the through hole 13, with the slot 221 located below the positioning block 62. Finally, the positioning block 62 is released, and the second spring 63 extends, thereby pressing the positioning block 62 into the slot 221. This completes the installation of the guide rod 2, and the operation is simple.

[0033] Specifically, see Figure 4 A plurality of second sliding posts 64 are fixed on the positioning block 62. The second sliding posts 64 are slidably connected to the fixing plate 61. The second spring 63 is sleeved on the second sliding posts 64, and its two ends abut against the fixing plate 61 and the positioning block 62 respectively. The above arrangement improves the stability of the positioning block 62 in the slot 221.

[0034] As described above, the positioning block 62 is provided with a handle 621 extending in the horizontal direction, so that the staff can move the positioning block 62 by using the handle 621.

[0035] In a preferred embodiment, see [reference] Figure 4 The support 1 includes an L-shaped frame 11 and two height-adjustable feet 12 located at the bottom of the L-shaped frame 11. Each height-adjustable foot 12 includes a base plate 121, on which a vertical rod 122 and a height-adjusting screw 123 are slidably connected to the L-shaped frame 11. Two positioning nuts 124 are mounted on the height-adjusting screw 123. The bottom of the L-shaped frame 11 is located between the two positioning nuts 124. Adjusting the position of the two positioning nuts 124 on the height-adjusting screw 123 adjusts the installation height of the L-shaped frame 11. When there is a height difference between the detection surface and the plane supporting the support 1, the installation height of the guide rod 2 can be adjusted by adjusting the support 1, thereby ensuring that the rebar cover measuring instrument can be in close contact with the detection surface for measurement.

[0036] In summary, this invention, by setting the slide 3 to move horizontally along the guide rod 2, allows the rebar cover thickness measuring instrument to move along a predetermined route. Furthermore, under the action of multiple pressing components 5, it ensures that the wheel surface of the rebar cover thickness measuring instrument remains in close contact with the detection surface throughout the measurement process, avoiding errors that could affect the measurement results. In addition, the use of the spliced ​​guide rod 2 and the clamping component 6 to achieve quick assembly and disassembly of the guide rod 2 and the bracket 1 improves the ease of use and applicability of the rebar cover thickness measuring device.
