Description

Technical Field

[0001] This invention relates to the technical field of concrete temperature monitoring, specifically to a large-volume concrete temperature monitoring device and its installation method. Background Technology

[0002] Currently, temperature measurement of large-volume concrete mainly adopts two methods: pre-embedded temperature measuring wires and pre-embedded temperature measuring tubes. The traditional pre-embedded temperature measuring tube method generally uses PVC pipes to pre-embed the temperature measuring wires. Since the PVC pipes create a vertically open airflow space, the temperature measuring point at the bottom of the pipe is easily affected by the airflow, resulting in inaccurate temperature measurement results. In addition, the temperature measuring tubes lack supports, making them difficult to fix. The pre-embedded temperature measuring wire method generally involves directly binding the temperature measuring wires to the vertical reinforcing bars before concrete construction. The disadvantage of this method is that the temperature measuring wires are directly exposed in the concrete. During concrete construction, the impact caused by pouring and vibration can easily damage the temperature measuring wires and temperature sensing elements, affecting temperature measurement.

[0003] To address the aforementioned issues, a large-volume concrete temperature measuring device can be described in existing technology (Chinese patent application number CN202422138281.9, application date August 30, 2024). This device, by incorporating a protective cylinder, elastic block, clamp, and support frame, houses the temperature measuring wire within the protective cylinder, preventing damage to the wire and temperature sensor during construction. Furthermore, the support component, made of a semi-open PVC pipe, effectively encloses the temperature sensor within the poured concrete, preventing the measuring tube from being easily damaged by external environmental factors. The invention also addresses the impact of environmental factors. Furthermore, reference can be made to a prior art (application number CN202020705736.X, application date 2020.04.30) that discloses a large-volume concrete temperature measuring device. This device can meet the requirements for temperature measurement of large-volume concrete of varying thicknesses, is highly applicable, and easy to operate. It can effectively protect the signal line from damage during use. In addition, this invention has a simple structure, is easy to source materials, and is low in cost. Using this invention for large-volume concrete temperature measurement provides accurate and reliable data while improving operational efficiency.

[0004] Although the above-mentioned device can realize the monitoring and processing of the convenience, there are still some shortcomings in the operation process. For example, when it is necessary to adjust the position of the collection box, it is necessary to avoid the assembled wires being stretched too much, as excessive stretching may lead to breakage during vibration later.

[0005] In view of this, a temperature monitoring device and installation method for large-volume concrete are proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a temperature monitoring device and installation method for large-volume concrete, in order to solve the problem mentioned in the background art that current temperature monitoring devices on the market need to avoid excessive stretching of the assembled wires when adjusting the position of the acquisition box, as excessive stretching can lead to breakage during vibration later.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A temperature monitoring device for large-volume concrete includes a vertical rod embedded in the concrete. A field acquisition box is installed at the upper end of the vertical rod, and a temperature monitoring device is connected to the field acquisition box via a connecting wire. A rotating component is provided at the top of the vertical rod, and the outer side of the rotating component is threadedly connected to the inner side of an adjusting rod. The field acquisition box is fixed to the outer side of the adjusting rod by a clamp. The rotating component includes a threaded rotating rod rotatably mounted at the top of the vertical rod. An elastic airbag is nested on the outer side of the bottom of the threaded rotating rod. The bottom of the elastic airbag is connected to a wire harness. The inner side of the wire harness is pressed against the outer side of the connecting wire to maintain the connection between the connecting wire and the temperature monitoring device when adjusting the height of the field acquisition box. A fixing block is fixed to the outer side of the vertical rod, and a mating block is fitted on the other side of the fixing block. The mating block is fixedly connected to the fixing block by a locking bolt. The temperature monitoring device is installed on the outer side of the fixing block.

[0009] Preferably, the temperature monitoring component includes a threaded mating block that is threaded to the end of the fixed block, a mating sleeve fixed on one side of the threaded mating block, a threaded fitting fixed on the end of the mating sleeve away from the threaded mating block, the outer side of the threaded fitting being threadedly connected to the inside of the assembly cylinder, and a temperature sensor body fixedly installed inside the assembly cylinder.

[0010] Preferably, the end of the connecting wire near the temperature monitoring component is connected to a mating wire, and a through hole is opened in the center of the threaded mating block. The outer end of the mating wire is embedded in the through hole and connected to the temperature sensor body.

[0011] Preferably, the bottom of the threaded rotating rod is nested on the outside of the rotating shaft, the bottom of the rotating shaft is connected to the inflatable air bladder through a flexible tube, and the outside of the inflatable air bladder is bonded and fixed in the hole of the cable tie frame.

[0012] Preferably, the elastic coefficient of the inflatable airbag is smaller than that of the elastic airbag, and the inflated airbag is attached to the outside of the connecting wire in the inflated state.

[0013] Preferably, the fixing block has a locking groove at one end near the mating block, and a limiting mechanism is provided at the end of the locking groove near the inner side of the mating block, with the limiting mechanism pressing against the outer side of the steel reinforcement frame.

[0014] Preferably, the limiting mechanism includes a piston strip slidably disposed inside the fixed block, the inner side of the piston strip being connected to the inside of the fixed block via a reset member; the fixed block has an air supply channel on the side near the piston strip, the other end of the air supply channel being connected to the cavity where the piston rod is located, the other end of the piston rod being connected to the end of the limiting ring via a cooperating spring, and the outer side of the limiting ring being slidably disposed inside the embedded groove.

[0015] Preferably, the reset component includes a fixing rod, a connecting spring, and a guide sleeve; the fixing rod is fixed to the outside of the piston bar, the end of the fixing rod is connected to the inside of the guide sleeve through the connecting spring, and the outer end of the guide sleeve is fixed to the inner wall of the fixing block.

[0016] Preferably, the outer side of the limiting ring is tightly fitted to the outer side of the reinforcing bar frame, and the embedded groove is opened at the center of the fixing block; the piston bar is in contact with the end of the locking bolt, and the contact end is provided with a wear-resistant rubber layer.

[0017] The method for embedding a temperature monitoring device for large-volume concrete, which is applied to temperature monitoring devices for large-volume concrete, is as follows:

[0018] S1: The vertical rod is secured to the steel reinforcement frame by the fixing block, the mating block and the locking bolt. Tightening the locking bolt drives the limiting mechanism to press the steel reinforcement frame, thus completing the positioning and fixing of the vertical rod.

[0019] S2: Thread the temperature monitoring component onto the outside of the fixing block, so that the mating wire passes through the through hole of the threaded mating block and is stably connected to the temperature sensor body;

[0020] S3: Insert the connecting wire into the hole of the cable tie frame, rotate the threaded rotating rod to compress the elastic air bladder and inflate it, so that the air bladder expands synchronously and presses and fixes the connecting wire.

[0021] S4: Rotate the adjusting rod to adjust the field data acquisition box to the preset height, and keep the connecting wires in a non-stretched and slack state;

[0022] S5: Embed the entire device into the area where a large volume of concrete is to be poured, and complete the embedding operation.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] This invention facilitates the installation of a large-volume concrete temperature monitoring device and its installation method. Through a linkage structure of elastic and inflatable air bladders, precise limiting and constraint of the connecting wires are achieved. Before adjusting the height of the on-site data acquisition box, manually squeezing the elastic air bladder delivers gas to the inflatable air bladder, causing it to expand and clamp the connecting wires near the temperature monitoring component. This prevents excessive stretching and breakage of the wires when the adjustment rod is rotated to lift the data acquisition box, completely overcoming the industry challenge of balancing height adjustment and wire protection. Simultaneously, the temperature monitoring component adopts a sealed threaded assembly structure, replacing the traditional through-type temperature measuring tube, eliminating interference from air convection on the temperature measurement data and ensuring accurate and reliable results. The fixing block and mating block, together with locking bolts, form a quick-fixing structure for the reinforcing steel frame, eliminating the need for binding, ensuring a secure installation that is not easily shifted, and effectively resisting the impact of concrete pouring and vibration, preventing damage to the wires and sensing elements. Specific details are as follows:

[0025] 1. The design of the elastic air bladder and the expansion air bladder with inflation limit solves the problem of easy stretching and breakage of the wires when adjusting the height of the data acquisition box. During the operation of adjusting the height of the data acquisition box on site, only the elastic air bladder at the top of the vertical rod needs to be manually squeezed to quickly deliver the internal gas into the expansion air bladder, causing the expansion air bladder to expand and press and limit the connecting wires near the temperature monitoring device, thus fixing the wires locally. At this time, rotating the adjustment rod to adjust the height of the data acquisition box will not stretch the limited wire segment as the data acquisition box moves, and it will always maintain a stable and relaxed connection state, effectively avoiding damage or breakage of the wires due to pulling, and ensuring stable transmission of temperature monitoring signals.

[0026] 2. The fixing block and mating block can be quickly and securely fastened to the rebar frame using locking bolts, ensuring a firm and stable installation that resists the impact of concrete construction and avoids the problems of device displacement and wire wear caused by traditional binding and fixing. The temperature monitoring component adopts a closed threaded assembly structure, which encloses and protects the temperature sensor body, eliminating any through-holes and accurately reflecting the internal temperature of the concrete. Combined with the sealed wiring assembly method, this further protects the sensor connection points. The overall device is easy to pre-embed and offers strong protection. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-9 The present invention provides the following technical solution: a temperature monitoring device for large-volume concrete.

[0039] Example 1: To address the issue in current market temperature monitoring devices where adjusting the position of the data acquisition box requires avoiding excessive stretching of the assembled wires, which can lead to breakage during later vibration, please refer to the attached... Figure 1 - Appendix Figure 3 and attached Figure 5The large-volume concrete temperature monitoring device is pre-embedded inside the large-volume concrete. The vertical rod 1 is a rigid rod pre-embedded vertically. The upper end of the vertical rod 1 is equipped with a height adjustment component, which includes a rotating part and an adjusting rod 4. The rotating part is rotatably set at the top of the vertical rod 1. The rotating part is specifically a threaded rotating rod 2. The outer side of the threaded rotating rod 2 is connected to the inner thread of the adjusting rod 4. The outer side of the adjusting rod 4 is detachably fixed to the field acquisition box 5 by a clamp. By rotating the adjusting rod 4, the field acquisition box 5 can be driven to rise and fall along the axial direction of the vertical rod 1, so as to realize the free adjustment of the height of the acquisition box.

[0040] To prevent the wire from stretching during height adjustment, the following is implemented: an elastic airbag 3 is nested on the outer side of the bottom of the threaded rotating rod 2. The bottom of the elastic airbag 3 is connected to the wire harness section via a hose. The wire harness section includes a wire harness frame 7 and an expansion airbag 8. The outer side of the expansion airbag 8 is bonded and fixed in a preset hole in the wire harness frame 7. The bottom of the threaded rotating rod 2 is nested on the outer side of the rotating shaft 31. The bottom of the rotating shaft 31 is sealed and connected to the expansion airbag 8 via a hose. The elastic coefficient of the expansion airbag 8 is less than that of the elastic airbag 3, ensuring that when the elastic airbag 3 is manually squeezed, gas can flow smoothly into the expansion airbag 8 to inflate it. The field acquisition box 5 is connected to the temperature monitoring device 12 via a connecting wire 6. The inner side of the inflated expansion airbag 8 is tightly fitted to the outer side of the connecting wire 6, forming a rigid limit on the wire segment near the temperature monitoring device 12.

[0041] A fixing block 9 is integrally fixed to the outer side of the vertical rod 1. A mating block 10 is fitted to one side of the fixing block 9. The mating block 10 is locked to the fixing block 9 by a locking bolt 11. A temperature monitoring component 12 is installed at the outer end of the fixing block 9. The temperature monitoring component 12 adopts a sealed assembly structure, including a threaded mating block 121, a mating sleeve 122, a threaded fitting 123, an assembly cylinder 124, and a temperature sensor body 125. The threaded mating block 121 is threaded to the end of the fixing block 9. The mating sleeve 122 is fixedly connected to one side of the threaded mating block 121. The threaded fitting 123 is fixed to the end of the mating sleeve 122 away from the threaded mating block 121. The outer thread of the threaded fitting 123 is screwed into the inside of the assembly cylinder 124. The temperature sensor body 125 is sealed and fixed inside the assembly cylinder 124. The end of the connecting wire 6 near the temperature monitoring component 12 is integrally connected to the mating wire 61. A sealing through hole is opened in the center of the threaded mating block 121. The outer end of the mating wire 61 is sealed and embedded in the through hole and stably connected to the temperature sensor body 125 to achieve a sealed wiring and prevent concrete slurry from seeping in.

[0042] Before adjusting the height of the on-site data acquisition box 5, the construction personnel manually squeeze the elastic airbag 3 at the top of the vertical rod 1. The gas inside the elastic airbag 3 is quickly delivered to the expansion airbag 8 through the hose. The expansion airbag 8 expands and presses and limits the connecting wire 6 near the temperature monitoring component 12, completely fixing the wire section. Then, the adjusting rod 4 is rotated to adjust the on-site data acquisition box 5 to the target height. The limited wire section will not be stretched as the data acquisition box moves, and will always remain in a relaxed and stable state, completely avoiding the wire from being stretched and broken. At the same time, the sealed assembled temperature monitoring component 12 can isolate the concrete slurry from external air interference, ensuring the accuracy of temperature monitoring data.

[0043] Example 2: This example differs from Example 1 in that it discloses that during concrete vibration, air bubbles inside the concrete rise to the surface, causing a positional deviation in the temperature sensor 125. For details, please refer to the appendix. Figure 1 and attached Figure 4 - Appendix Figure 9 An automatic locking limiting mechanism is added at the mating position of the fixing block 9 and the mating block 10 to achieve a gapless clamping and fixing of the device and the steel frame 21, and to completely prevent position displacement after pre-embedding. The specific structure is as follows: an arc-shaped locking groove 13 is opened at one end of the fixing block 9 near the mating block 10. The locking groove 13 is used to lock the steel frame 21. A limiting mechanism is set at one end of the locking groove 13 near the inner side of the mating block 10. The limiting mechanism is tightly pressed against the outer surface of the steel frame 21.

[0044] The piston strip 14 is slidably disposed in the cavity inside the fixed block 9. The inner side of the piston strip 14 is elastically connected to the inside of the fixed block 9 through the reset component 15. The reset component 15 is specifically composed of a fixed rod 151, a connecting spring 152 and a guide sleeve 153. The fixed rod 151 is fixed to the outer end of the piston strip 14. The end of the fixed rod 151 away from the piston strip 14 is elastically connected to the inside of the guide sleeve 153 through the connecting spring 152. The outer end of the guide sleeve 153 is fixed to the inner wall of the fixed block 9 to realize the automatic reset of the piston strip 14.

[0045] A sealed gas delivery channel 16 is opened inside the fixed block 9 on the side near the piston strip 14. One end of the gas delivery channel 16 is connected to the cavity where the piston strip 14 is located, and the other end is connected to the sealed cavity where the piston rod 17 is located. The piston rod 17 is sealed and slidably disposed in the cavity. The end of the piston rod 17 away from the gas delivery channel 16 is elastically connected to the end of the limiting ring 19 through a cooperating spring 18. The outer side of the limiting ring 19 is slidably disposed in the embedding groove 20 in the middle of the fixed block 9. The inner side of the limiting ring 19 is an arc-shaped surface that fits tightly against the outer side of the steel frame 21. The piston strip 14 is in contact with the end of the locking bolt 11, and the surface of the contact end is provided with a wear-resistant rubber layer to improve service life and sealing effect.

[0046] After the fixing block 9 and the mating block 10 are engaged on the outside of the steel frame 21, tighten the locking bolt 11. The end of the locking bolt 11 pushes the piston strip 14 to slide into the fixing block 9. The piston strip 14 compresses the air in the cavity. The air pressure pushes the piston rod 17 out through the air supply channel 16. The piston rod 17 drives the limiting ring 19 to slide out of the embedded groove 20 and hug the steel frame 21, forming a double locking fixation. When the concrete is vibrated and the air bubbles rise, the device as a whole does not shake or shift. The temperature sensor body 125 always stays at the preset temperature measurement point to ensure that the monitoring data is true and accurate. When disassembling, loosen the locking bolt 11. The reset part 15 drives the piston strip 14 to reset, the cavity is depressurized, and the spring 18 pulls the limiting ring 19 back into the embedded groove 20, so that the device can be quickly removed.

[0047] The method for embedding a temperature monitoring device for large-volume concrete, which is applied to temperature monitoring devices for large-volume concrete, is as follows:

[0048] S1: The vertical rod 1 is clamped onto the steel frame 21 by the fixing block 9, the mating block 10 and the locking bolt 11. Tightening the locking bolt 11 drives the limiting mechanism to press the steel frame 21, thus completing the positioning and fixing of the vertical rod 1.

[0049] S2: The temperature monitoring component 12 is threaded onto the outside of the fixing block 9, so that the mating wire 61 passes through the through hole of the threaded mating block 121 and is stably connected to the temperature sensor body 125.

[0050] S3: Insert the connecting wire 6 into the hole of the cable tie 7, rotate the threaded rotating rod 2 to compress the elastic air bag 3 to inflate it, so that the expansion air bag 8 expands synchronously and presses and fixes the connecting wire 6.

[0051] S4: Rotate the adjusting rod 4 to adjust the field acquisition box 5 to the preset height, and keep the connecting wire 6 in a relaxed state without tension;

[0052] S5: Embed the entire device into the area where a large volume of concrete is to be poured, and complete the embedding operation.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
