Description

Technical Field

[0001] This application relates to the technical field of foundation pit engineering, and in particular to a safety detection device for foundation pit engineering. Background Technology

[0002] Foundation pit engineering is a systematic project integrating geological engineering, geotechnical engineering, structural engineering, and geotechnical testing technology. Its main components include engineering survey, support structure design and construction, earthwork excavation and backfilling, groundwater control, information-based construction, and surrounding environmental protection. During construction, it is often necessary to use safety monitoring devices to inspect the internal condition; common safety monitoring devices include stress testing devices.

[0003] Among them, the stress detection device is used to detect the stress of the steel bars in real time, so as to avoid the foundation strength of the pit not meeting the standard due to insufficient steel bar stress, thereby eliminating the safety hazards caused by this.

[0004] In the process of testing the strength of reinforcing bars using stress testing devices, the traditional stress testing devices require workers to connect the connecting rod to the reinforcing bars and then weld them together using electric welding.

[0005] Although this connection method is simple, it is limited by tools during the connection process. Secondly, the high temperature generated during welding will cause local changes in the metallographic structure of the steel bar, reducing the strength, toughness and ductility of the welded area and heat-affected zone. This can easily lead to stress concentration, coarse grains or embrittlement, thereby reducing the overall load-bearing capacity and structural safety of the steel bar.

[0006] Meanwhile, during the welding process, if the stress device tilts outside the reinforcing bar, it will cause errors in the test data. If the tilt is severe, it may even prevent the other end from being effectively connected to the reinforcing bar, thus affecting the test results. Summary of the Invention

[0021] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0022] The safety detection device for foundation pit engineering according to an embodiment of this application will be described below with reference to the accompanying drawings.

[0023] The stress detection device provided in this application embodiment can be applied to stress detection of reinforcing steel in foundation pits and other engineering projects.

[0024] like Figure 1-3 As shown in the figure, the foundation pit engineering safety detection device of this application embodiment includes a stress detection device 1 and four sets of connecting mechanisms 2.

[0025] The stress detection device 1 includes two second connecting rods 15, and four sets of connecting mechanisms 2 are respectively arranged in pairs outside the corresponding second connecting rods 15.

[0026] Each connecting mechanism 2 includes a first metal ring 21, a second metal ring 22, a limiting mechanism 23, a first fixing mechanism 24, two sets of adjusting mechanisms 25, two clamping plates 26, a push plate 27, two sets of fastening mechanisms 28, and a second fixing mechanism 29.

[0027] The first metal ring 21 and the second metal ring 22 are pivotally connected. The limiting mechanism 23 is disposed on the inner wall of the first metal ring 21 and the second metal ring 22. The first fixing mechanism 24 is disposed on the outer wall of the first metal ring 21 and the second metal ring 22, away from the connection point of the first metal ring 21 and the second metal ring 22. Two sets of adjusting mechanisms 25 are respectively disposed on the outer wall of the first metal ring 21 and the second metal ring 22, and located on both sides of the connection point of the first metal ring 21 and the second metal ring 22. Two clamping plates 26 are respectively adjustablely disposed on the outer wall of the first metal ring 21 and the second metal ring 22 through the corresponding adjusting mechanisms 25. Two sets of fastening mechanisms 28 are respectively disposed on the inner wall of the two clamping plates 26. The second fixing mechanism 29 is disposed on the outer wall of the two sets of clamping plates 26, away from the adjusting mechanism 25.

[0028] It should be noted that the first metal ring 21, the second metal ring 22, and the clamping plate 26 described in this embodiment are all made of spring steel. Firstly, this ensures their strength. Secondly, during the connection process, the first metal ring 21, the second metal ring 22, and the clamping plate 26 can undergo a certain degree of deformation.

[0029] Specifically, when it is necessary to connect the stress detection device 1 to the reinforcing bar, the worker can install the first metal ring 21 and the second metal ring 22 to the outside of the second connecting rod 15 through the limiting mechanism 23, and then fix them to the outside of the second connecting rod 15 with the first fixing mechanism 24. Then, fix the two clamping plates 26 to the outside of the reinforcing bar, and then fix them to the outside of the reinforcing bar with the second fixing mechanism 29. During the connection process, the fastening mechanism 28 will make the connection with the reinforcing bar more stable, and at the same time, the adjusting mechanism 25 will change with the diameter of the reinforcing bar during the fixing process.

[0030] like Figure 3 As shown, in one embodiment of this application, each set of limiting mechanisms 23 includes two limiting blocks 232.

[0031] The second connecting rod 15 has symmetrically formed limiting grooves 231 on its outer wall, and two limiting blocks 232 are respectively set on the inner walls of the first metal ring 21 and the second metal ring 22. The first metal ring 21 and the second metal ring 22 are installed on the outer wall of the second connecting rod 15 through the corresponding limiting grooves 231.

[0032] The first fixing mechanism 24 includes a first fixing plate 241, a second fixing plate 242, a plurality of first nuts 243 and a plurality of first bolts 244.

[0033] The first fixing plate 241 and the second fixing plate 242 are respectively disposed on the side walls of the first metal ring 21 and the second metal ring 22. A plurality of first nuts 243 are equidistantly disposed on the bottom wall of the second fixing plate 242. A plurality of first bolts 244 pass through the first fixing plate 241 and the second fixing plate 242 respectively and are threadedly connected to the corresponding first nuts 243.

[0034] Specifically, when installing the first metal ring 21 and the second metal ring 22 onto the outer wall of the second connecting rod 15, the operator can open the first metal ring 21 and the second metal ring 22, and then install the first metal ring 21 and the second metal ring 22 onto the outer wall of the second connecting rod 15 along the inner wall of the limiting block 232.

[0035] Then, the first bolt 244 is rotated sequentially through the first fixing plate 241 and the second fixing plate 242 and then threadedly connected to the corresponding first nut 243, thereby fixing the first metal ring 21 and the second metal ring 22 to the outer wall of the second connecting rod 15.

[0036] like Figure 3 As shown, in one embodiment of this application, each set of adjustment mechanisms 25 includes a support block 251 and a connecting block 253.

[0037] The support block 251 is disposed on the outer wall of the first metal ring 21, and the side wall of the support block 251 is provided with a sliding groove 252. The connecting block 253 is slidably connected to the support block 251.

[0038] Specifically, during the process of fixing the two clamping plates 26 to the outside of the reinforcing bars, as the tightening process proceeds, the two clamping plates 26 will move the connecting block 253 along the inner wall of the slide groove 252 according to the diameter of the reinforcing bars, thereby enabling the use of reinforcing bars of different diameters.

[0039] like Figure 3 As shown, in one embodiment of this application, the fastening mechanism 28 includes a plurality of elastic elements 282 and a plurality of connecting posts 283.

[0040] The inner wall of the card plate 26 is provided with storage holes 281 at equal intervals. One end of a plurality of elastic elements 282 is connected to the inner bottom wall of the corresponding storage hole 281, and a plurality of connecting posts 283 are connected to the other end of the corresponding elastic element 282.

[0041] It should be noted that the multiple elastic elements 282 described in this embodiment are springs.

[0042] Each group of second fixing mechanisms 29 includes a first fastening plate 291, a second fastening plate 292, a plurality of second nuts 293 and a plurality of second bolts 294.

[0043] The first fastening plate 291 and the second fastening plate 292 are respectively disposed on the side walls of the two clamping plates 26, and a plurality of second nuts 293 are equidistantly disposed on the bottom wall of the lower second fastening plate 292. A plurality of second bolts 294 pass through the two second fastening plates 292 and are threadedly connected to the corresponding second nuts 293.

[0044] Specifically, during the process of connecting the reinforcing bars, the workers can place two clamping plates 26 outside the reinforcing bars, and then rotate the second nut 293 in sequence to pass through the two second fastening plates 292 and connect it with the corresponding second nut 293 threadedly.

[0045] As the second nut 293 rotates, the push plate 27 applies pressure to the elastic element 282. At this time, the elastic element 282 stores and compresses, and the connecting column 283 moves along the inner wall of the receiving hole 281. During the process of storing and compressing the elastic element 282, the elastic element 282 generates a reaction force that is applied to the reinforcing bar through the push plate 27, thereby making the fixation more stable.

[0046] like Figure 2 As shown, in one embodiment of this application, the stress detection device 1 further includes a main body 11, two first connecting rods 12 and two threaded rods 14.

[0047] One end of each of the two first connecting rods 12 is connected to both ends of the main body 11, and the other end of each of the two first connecting rods 12 is provided with a threaded groove 13. Two threaded rods 14 are respectively provided at one end of the corresponding second connecting rods 15. The two second connecting rods 15 are respectively threadedly connected to the corresponding threaded grooves 13 through the corresponding threaded rods 14. The wire 16 is connected to one of the first connecting rods 12.

[0048] Specifically, during the process of detecting the stress of the reinforcing steel, the staff can connect the terminal to the stress detection device 1 via the wire 16. Then, the changes in physical quantities such as frequency, strain, sound velocity, magnetic properties or lattice spacing caused by the stress on the reinforcing steel, which are followed by the second connecting rod 15, will be transmitted to the terminal through the main body 11. After calibration, conversion and temperature compensation, the stress value will be presented to the staff.

[0049] like Figure 3 As shown, in one embodiment of this application, the inner walls of the plurality of push plates 27 are respectively provided with buffer pads 210.

[0050] It should be noted that the buffer pad 210 described in this embodiment is a rubber pad.

[0051] Understandably, the friction between the push plate 27 and the second connecting rod 15 can be increased by setting the buffer pad 210.

[0052] In summary, the foundation pit engineering safety detection device of this application embodiment, by adding an installation mechanism to the outside of the stress detection device, allows workers to install the stress detection device to the outside of the reinforcing steel using a metal ring. Then, it is fixed to the outside of the reinforcing steel using a fixing mechanism, connected to the reinforcing steel using a clamping plate, and finally, the reinforcing steel and the stress detection device are tightly connected using a fixing mechanism. At the same time, the connection is ensured by the fastening mechanism during the connection process, thereby ensuring that the reinforcing steel is not affected by the high temperature during the welding process, thus ensuring normal detection of the reinforcing steel and ensuring that the overall stress performance and structural safety of the reinforcing steel are not affected.

[0053] Meanwhile, by optimizing the intelligent control structure, the monitoring function for low temperature is added. When the monitoring component detects that the temperature is too low, the protection component can be automatically activated to appropriately heat the inside. When the temperature rises to the set temperature, the heating will automatically stop.
