[0002] The vibrating wire type steel stress meter is a kind of instrument specially designed for long-term monitoring the internal steel stress of hydraulic structure and other concrete structures.The traditional stress meter structure mainly includes stress meter main body, sleeve (also known as pull rod sleeve) and pull rod three components.In these components, the pull rod plays a key role of being directly connected with steel, and its connection mode mainly has two kinds of binding and welding, and the welding mode is more preferred due to its stability.

[0003] However, it is worth noting that the traditional pull rod structure has obvious deficiency in positioning, which leads to having to rely on external tools or manual assistance to ensure the accuracy of welding in welding operation.More troublesome is that the high temperature generated in the welding process poses a potential threat to the stress meter.In order to effectively alleviate the adverse effects of high temperature, the common practice at present is to water or wrap with wet cloth in the sensor area (i.e.stress meter part) to achieve cooling, so as to prevent the damage of sensor caused by high temperature.Although these measures have played a protective role to some extent, there is still a risk of high temperature affecting the sensor area.

[0004] Therefore, it is necessary to invent a novel steel stress meter. UTILITY MODEL CONTENTS

[0012] The utility model discloses discard the traditional integral type pull rod structure design, and instead adopts an innovative splicable module type pull rod scheme.The core of the scheme lies in the ingenious cooperation of the unique positioning limiting structure - positioning ring and butt joint bolt.Through the cooperation mechanism, the welding rod can be stably installed on the pile reinforcement, and accurate and firm welding connection can be realized without relying on additional tools or manual assistance during the welding process.

[0013] Especially important is that during the welding operation, the module type pull rod and the pull rod sleeve of the reinforcement stress meter body are in a separated state.This design fundamentally blocks the path of high temperature generated by welding to the reinforcement stress meter body through the module type pull rod, thereby completely eliminating the potential harm of high temperature to the sensor and significantly reducing the risk of damage to the sensor area.Therefore, without taking traditional cooling measures such as watering or wet cloth wrapping, the stability and reliability of the monitoring system can be significantly improved.This innovation not only simplifies the operation process, but also further enhances the durability and long-term monitoring accuracy of the system.

[0021] As shown in the accompanying Figure 1 to the accompanying Figure 3 :

[0022] The utility model provides a novel steel stress meter, including steel stress meter main part 1, pull rod sleeve 2, module type pull rod 3, stake reinforcement 4 and wire 5, steel stress meter main part 1 is connected with corresponding module type pull rod 3 respectively through the pull rod sleeve 2 of both ends of itself, every module type pull rod 3 is connected with corresponding stake reinforcement 4 respectively, two stake reinforcements 4 are mirror image symmetry and set up, the wire 5 of steel stress meter main part 1 leads to ground surface.

[0023] Further, the module type pull rod 3 includes a joint 31, a butt bolt 32, a welding rod 33, and a positioning ring 34. One end of the joint 31 is designed with a thread, which can be tightly threadedly engaged with the pull rod sleeve 2, ensuring the stable connection of the pull rod with the stress meter main body 1. The other end of the joint 31 is connected with the welding rod 33 through the butt bolt 32, forming a detachable and stable assembly structure.

[0024] Further, the end of the welding rod 33 is specially designed with a butt protrusion 35, and the end of the joint 31 connected with the welding rod 33 is specially designed with a butt notch 36. The butt protrusion 35 and the butt notch 36 are matched in shape and size, which not only enhances the stability of the connection, but also facilitates quick positioning and assembly.

[0025] Further, through holes 37 are provided at the end of the joint 31 with the butt notch 36 and at the butt protrusion 35. These through holes 37 allow the butt bolt 32 to pass through, and one end of the butt bolt 32 is allowed to be placed on the surface of the pile reinforcement 4, thereby achieving a firm connection between the welding rod 33 and the pile reinforcement 4.

[0026] Further, the through holes 37 provided at the butt protrusion 35 are designed as threaded holes. The threads of the butt bolt 32 are tightly matched with these threaded holes, and a more stable threaded connection can be achieved by rotating the bolt, further enhancing the connection strength between the modular pull rod 3 and the pile reinforcement 4.

[0027] Further, the end of the welding rod 33 is also provided with a positioning ring 34, which is cleverly designed at the end away from the reinforcement stress meter body 1 and has a "U" shape structure. The positioning ring 34 facilitates accurate sleeving of the welding rod 33 on the pile reinforcement 4.

[0028] The working principle is as follows: Before installing the self-vibrating string type reinforcement stress meter at the predetermined position of the reinforcement cage, the first step is to accurately cut the target reinforcement (i.e. the pile reinforcement 4) in the reinforcement cage. The length of the cut needs to be accurately matched with the installation requirements of the self-vibrating string type reinforcement stress meter to ensure accuracy and stability after installation.

[0029] Next, according to the specifications of the cut pile reinforcement 4, select the corresponding size of the modular pull rod 3 for installation. The installation of the modular pull rod 3 starts with sleeving the welding rod 33 through the positioning ring 34 on the pile reinforcement 4. To prevent loosening during subsequent operations, the butt bolt 32 needs to be installed on the butt protrusion 35 at the end of the welding rod 33 and tightened moderately to ensure that the end surface of the butt bolt 32 tightly fits the surface of the pile reinforcement 4, thereby achieving firm positioning connection of the two.

[0030] After the above positioning is completed, welding operation can be performed to firmly weld the welding rod 33 and the pile reinforcement 4 together. This process needs to be operated on two modular pull rods 3 respectively to ensure that the two welding rods 33 are respectively connected with the corresponding pile reinforcement 4 stably. Subsequently, the joint 31 of the modular pull rod 3, i.e. the end with threads, is threadedly engaged with the pull rod sleeve 2 to further reinforce the entire structure.

[0031] After the welding of the welding rods 33 with the pile reinforcement 4 is completed, and the joint 31 is firmly connected with the pull rod sleeve 2, the next step is to temporarily remove the butt joint bolt 32 from the welding rod 33 in order to prepare for the subsequent butt joint. At this time, the reinforcement stress meter body 1 with the joint 31 installed is carefully clamped between the two welding rods 33. In this process, the butt joint gap 36 of the joint 31 needs to be accurately matched with the butt joint protrusion 35 on the welding rod 33 to ensure that the two can be seamlessly butt jointed.

[0032] Finally, by reinstalling and tightening the butt joint bolt 32, the joint 31 is firmly connected with the welding rod 33 (specifically through the butt joint protrusion 35). This step not only completes the assembly of the modular pull rod 3 with the reinforcement stress meter body 1, but also ensures the stability and reliability of the entire stress monitoring system. At this point, the entire installation process is successfully completed, and the vibrating wire reinforcement stress meter is ready for its stress monitoring task.

[0033] The technical scheme disclosed by the utility model, or the technical scheme designed by the person skilled in the art under the inspiration of the technical scheme of the utility model, and the similar technical scheme achieving the above technical effects all fall within the protection scope of the utility model.
