Description

Technical Field

[0001] This utility model relates to the field of rebar gauge measurement technology, and specifically to a rebar gauge connection device. Background Technology

[0002] A rebar gauge is a high-precision measuring instrument primarily used to monitor and record stress changes in reinforcing bars under various environmental conditions. Rebar gauges are typically embedded in various concrete engineering projects, such as building foundations, pile foundations, diaphragm walls, tunnel linings, bridges, and slopes. By fixing the gauge to the reinforcing bar, it can acquire real-time stress data, thereby determining whether the bar is within a safe operating range. The gauge accurately measures stress changes in the reinforcing bar, especially in concrete structures such as bridges, dams, or high-rise buildings. The gauge provides real-time feedback of stress values ​​through changes in the frequency of its internal vibrating wire. This monitoring is like a regular check-up, promptly detecting whether the reinforcing bar is "over-fatigued," avoiding the risk of breakage due to overloading. Rebar gauges are usually distributed and centrally measured to collect data. A large number of gauges are pre-embedded, each with two cables, resulting in dozens of cables at a single measurement point. During measurement, multiple cables need to be identified and matched, and then a portable frequency reader is used to collect the data. The large number of cables introduces many inconveniences to the measurement process. Utility Model Content

[0040] like Figure 1-6 As shown, the rebar connection device includes a wiring section, which includes a connecting end 1 and a sealing end 2. N wiring plates 3 are provided between the connecting end 1 and the sealing end 2, where N is an integer greater than or equal to one.

[0041] The connecting end 1, the N terminal blocks 3, and the sealing end 2 are sequentially and detachably connected.

[0042] Each terminal block 3 is provided with a first rectangular groove 4 and a second rectangular groove 5, and the length of the two is equal to the length of the terminal block 3. The first rectangular groove 4 and the second rectangular groove 5 are the same size and are arranged symmetrically front and back.

[0045] The right end face of the connecting end 1 is provided with two connecting holes 10 for connecting the frequency reading instrument 11. The two acquisition ends of the frequency reading instrument 11 are connected to the right ends of the first metal strip 6 and the second metal strip 7 respectively through the two connecting holes 10. In use, the two wires of the rebar gauge are connected to the first terminal 8 and the corresponding second terminal 9 respectively. During measurement, it is only necessary to slide the first terminal 8 inward until its rear end face is in complete contact with the front end face of the first metal strip 6, and slide the corresponding second terminal 9 inward until its rear end face is in complete contact with the rear end face of the second metal strip 7. The remaining first terminal 8 is separated from the first metal strip 6, and the remaining second terminal 9 is separated from the second metal strip 7. The rebar gauge can then be measured by the frequency reading instrument 11. After the measurement is completed, the first terminal 8 and the corresponding second terminal 9 are pulled outward. By repeating the above steps, multiple rebar gauges can be measured.

[0046] like Figure 3 , Figure 4As shown, in this embodiment, preferably, the sliding structure includes multiple sliding holes 12 disposed on the front or rear end face of the terminal block 3 and communicating with the corresponding rectangular grooves.

The two first plugs 14 on the left end face of the right terminal block 3 are respectively located on the two first sockets 13 on the right end face of the adjacent left terminal block 3, and the two are interference fit. That is, the first plugs 14 and the corresponding first sockets 13 require external force to be inserted and separated, and will not separate naturally.

[0049] The left end face of the connecting end 1 is provided with two second insertion rods 15, which correspond to the two first insertion holes 13 located on the far right. The two second insertion rods 15 are respectively located in the two corresponding first insertion holes 13 and are interference fit. That is, the second insertion rods 15 and the corresponding first insertion holes 13 require external force to be inserted and separated, and will not separate naturally.

[0050] The right end face of the sealing end 2 is provided with two second insertion holes 16, which correspond to two first insertion rods 14 located on the left end face of the leftmost terminal block 3. The two first insertion rods 14 are respectively located in the two second insertion holes 16 and are interference fit.

A connecting hole 19 adapted to the connecting post 18 is provided on the left end face of each first metal strip 6 or second metal strip 7.

[0053] The connecting post 18 of the metal strip on the left extends into the connecting hole 19 of the adjacent metal strip on the right, and the two are interference-fitted. By plugging them in, the integrity of the metal strip connection can be ensured, the inaccuracy of measurement due to poor contact can be effectively avoided, and the stability of the connection between the N terminal blocks 3 can be further enhanced.

[0054] like Figure 2 As shown in this embodiment, in order to avoid external rainwater and other factors causing corrosion to the metal strip and affecting its service life and accuracy, a baffle 20 made of transparent material is provided above the first rectangular groove 4 and the second rectangular groove 5. The baffle 20 can seal the upper end of the corresponding rectangular groove to reduce external rainwater and other factors from causing corrosion to the metal strip. In addition, the use of transparent material also makes it easier to observe whether the first connecting post 18 or the second connecting post 18 is in complete contact with or separated from the corresponding metal strip, further improving the accuracy of the measurement.

[0055] like Figure 6As shown in this embodiment, in order to facilitate the fixing of the rebar connection device, a fixing clip 21 for fixing the entire device is provided on the left end face of the sealing end 2.

[0057] like Figure 8 As shown, in this embodiment, in order to facilitate the correspondence between the corresponding terminals and the rebar gauge, a plurality of first numbers 22 are sequentially arranged on the front edge of the upper surface of the terminal block 3. The plurality of first numbers 22 are generally numbered sequentially as 1, 2, 3... The number of the plurality of first numbers 22 is the same as the number of the plurality of first terminals 8 and corresponds one-to-one.

[0058] Multiple second numbers 23 are sequentially arranged on the rear edge of the upper surface of the terminal block 3. The multiple second numbers 23 are generally numbered sequentially as 1, 2, 3... The number of multiple second numbers 23 is the same as the number of multiple second terminals 9 and corresponds one-to-one. The two ends of the two cables of the same steel bar are respectively connected to the first terminal 8 and the second terminal 9 with the same number for easy matching.

[0059] like Figure 9 As shown, in this embodiment, to prevent the cables and terminals from being corroded by rainwater, a plurality of first terminals 8 and a plurality of second terminals 9 are fitted with protective sleeves 24. The protective sleeves 24 are made of transparent flexible material, and elastic cords are provided at both ends of the protective sleeves 24. By binding the terminals and cables with elastic cords, the terminals and cable connectors can be effectively protected from corrosion by rainwater, etc., thus improving their service life. Since they are made of transparent flexible material, they will not affect the operation of the terminals.
