Description

TECHNICAL FIELD

[0001] The utility model relates to engineering construction tool technical field, specifically, relate to a prefabricated pile end reinforcement horizontal tensile force frock. BACKGROUND

[0002] In the field of building engineering foundation construction, the wide application of prefabricated piles puts forward strict requirements for the accurate and stable connection of the prefabricated piles and the foundation slab structure, and the position adjustment quality of the prefabricated pile end reinforcement directly affects the overall connection effect and the stability of the building foundation, but the traditional related adjustment methods have many disadvantages.

[0003] The traditional adjustment method is not satisfactory in dealing with the diversity of prefabricated pile specifications and reinforcement layout. The cross section of prefabricated pile is rich in shape, including round, square and even polygon, and the internal reinforcement arrangement is complex and variable, including annular, square and irregular distribution. However, the traditional adjustment frock is usually fixed and rigid in structure, lacks the mechanism of flexible adaptation to different reinforcement positions, and cannot accurately position the end of each reinforcement when facing the diversified reinforcement layout. Therefore, a large amount of manpower and time is needed to manually move the reinforcement to the approximate position, which is not only low in efficiency, but also may cause hidden troubles in subsequent construction due to inaccurate positioning, and the universality is seriously limited.

[0004] In terms of precision control of the position of the reinforcement end, the traditional method relies on the rough experience of workers and lacks precise driving and positioning system. At the key construction node of the connection between the prefabricated pile and the slab, the end of the reinforcement needs to be accurately inserted into the reserved hole or overlapped with the reinforcement of the slab according to the design, and even a small error may weaken the connection strength and damage the integrity of the structure. However, the traditional method cannot accurately push the reinforcement to move according to the set displacement, resulting in large deviation of the position of the reinforcement end and damage to the bearing and force transmission stability of the building foundation.

[0005] On the foundation support structure, the old frock is poor in strength and stability. The construction site is complex, and the reinforcement needs to withstand many external forces such as self weight, friction and operation impact during adjustment. The fragile support structure is easy to sway and deform, which cannot provide a solid foundation for adjustment operation, interferes with the normal operation of fixed and adjusted parts, increases the risk of construction accidents, and hinders the smooth progress of the adjustment process.

[0040] Reference Figs. 1-3 For the first embodiment of the utility model, a prefabricated pile end steel bar transverse tension tool is proposed, which is used for adjusting the position of the steel bar end of the prefabricated pile, comprising a fixed seat 1, the fixed seat 1 has a sliding groove 101, a sliding part 2 is slidably arranged in the sliding groove 101, the sliding part 2 has a fixed cavity 201, the fixed cavity 201 is used for accommodating the end of the steel bar, an adjusting part 3 is arranged on the fixed seat 1, which is used for adjusting the position of the sliding part 2.

[0041] In the embodiment, the sliding groove 101 arranged on the fixed seat 1 and the sliding part 2 slidably arranged in the sliding groove 101 make the tool flexible to adapt to different steel bar end layouts in the prefabricated pile. In actual construction engineering, the specifications and sizes of prefabricated piles are various, and the arrangement and quantity of the internal steel bars are also different. For example, some prefabricated piles may be circular in cross section, and the internal steel bars are uniformly distributed in a ring shape; some are square in cross section, and the steel bars are arranged in a square grid. The structure of the tool can accommodate and position the end of each steel bar by sliding the sliding part 2 in the sliding groove 101 to the appropriate position according to the steel bar distribution of the specific prefabricated pile, through the use of multiple fixed seats 1 and sliding parts 2, effectively solving the adjustment problem caused by the difference in the layout of the steel bars of the prefabricated pile, and improving the universality and applicability of the tool.

[0042] The adjusting member 3 is arranged on the fixed base 1 to drive the sliding member 2 to slide, which realizes the accurate control of the position of the reinforcing steel bar end. In the construction of the building, the position accuracy of the reinforcing steel bar end of the precast pile is required to be high. When the precast pile and the foundation slab are connected, the reinforcing steel bar end needs to be accurately inserted into the reserved hole of the foundation slab or accurately overlapped with the reinforcing steel bars of the foundation slab. The reinforcing steel bar end accommodated in the fixed cavity 201 can be moved to the specified accurate position by accurately driving the sliding member 2 to slide in the sliding groove 101 by the adjusting member 3. For example, when the reinforcing steel bar end needs to be extended outward by a certain length to meet the overlapping requirement with the reinforcing steel bars of the foundation slab, the adjusting member 3 can smoothly push the sliding member 2 to slide in the sliding groove 101 according to the set displacement, so that the reinforcing steel bar end accurately reaches the required position, ensuring the quality of the connection between the precast pile and the foundation slab, and improving the integrity and stability of the building foundation structure.

[0043] The fixed base 1 has sufficient strength and stability as the basic support structure of the tooling. It can withstand various forces generated during the adjustment of the reinforcing steel bar end, such as friction when the sliding member 2 slides, the weight of the reinforcing steel bar, and impact forces that may be generated due to improper operation. In the construction site, when workers use the adjusting tooling to adjust the reinforcing steel bars of the heavy and long precast pile, the fixed base 1 can still be stably placed on the workbench or the ground without shaking or deforming, providing a reliable installation foundation for the sliding member 2 and the adjusting member 3, ensuring the normal operation of the entire tooling, and ensuring that the adjustment of the reinforcing steel bar end can be smoothly carried out.

[0044] Meanwhile, the fixed cavity 201 of the sliding member 2 has a good fixing effect on the reinforcing steel bar end. After the reinforcing steel bar end is inserted into the fixed cavity 201, its shape and size design can prevent the reinforcing steel bar from shaking or deviating during the adjustment. For example, for reinforcing steel bars of different diameters, the fixed cavity 201 can be designed with an adjustable inner diameter to ensure that the reinforcing steel bar can be stably fixed in the fixed cavity 201 regardless of its thickness, further ensuring the accuracy and stability of the adjustment of the reinforcing steel bar end.

[0045] The sliding cooperation between the sliding groove 101 and the sliding member 2 is very smooth, which is beneficial to improve the work efficiency and reduce the wear of the parts. In the daily use of the adjusting tooling, the sliding member 2 needs to frequently slide in the sliding groove 101. The smooth sliding cooperation enables the sliding member 2 to quickly respond to the driving instructions of the adjusting member 3 and quickly move to the specified position, greatly shortening the adjustment time of each reinforcing steel bar end and improving the overall work efficiency. Moreover, the smooth sliding cooperation reduces the friction between the sliding member 2 and the sliding groove 101, prolongs the service life of the parts, reduces the maintenance cost of the tooling, and ensures the reliability and usability of the tooling in the long-term construction process.

[0046] The operation process of the reinforcing steel bar adjusting tool is simple and intuitive, and construction personnel can quickly get started. First, the reinforcing steel bar end of the precast pile is inserted into the fixed cavity 201 of the corresponding sliding member 2 in sequence; then, according to the specific requirements of the precast pile and subsequent construction links such as connection with the pile cap, the sliding member 2 is driven to slide in the sliding groove 101 by the adjusting member 3 to adjust the position of the reinforcing steel bar end; finally, after the adjustment is completed, the reinforcing steel bar is taken out from the fixed cavity 201. The whole operation process is clear and easy to understand, and construction personnel do not need to have too high professional skills, which reduces the training cost of construction personnel and improves the overall work efficiency of the construction team.

[0047] Further, the sliding member 2 has a first threaded hole 202, and the adjusting member 3 is a lead screw, which is rotationally arranged on the fixed seat 1 and located in the sliding groove 101, and is arranged in the first threaded hole 202 for adjusting the position of the sliding member 2.

[0048] In this embodiment, the adjusting member 3 adopts the design of a lead screw, which is rotationally arranged on the fixed seat 1 and located in the sliding groove 101, and drives the sliding member 2 to slide by cooperating with the first threaded hole 202 of the sliding member 2. This structure brings very high precision to the adjustment of the reinforcing steel bar end position. The lead screw has good transmission accuracy. When the lead screw is rotated, the threads of the lead screw and the threads in the first threaded hole 202 of the sliding member 2 interact with each other, and can accurately convert the rotary motion of the lead screw into the linear sliding motion of the sliding member 2. Moreover, the lead screw driving mode can realize fine adjustment and meet the fine adjustment requirements of the reinforcing steel bar end position in different construction scenes. For example, in some special building projects such as large bridge foundation precast pile construction, which have very high requirements for the reinforcing steel bar end position, it may be necessary to fine-tune the reinforcing steel bar end position by 0.1 millimeter. The precise transmission characteristics of the lead screw make it easy to realize such fine-tuning operation, ensuring that the reinforcing steel bar end position always meets strict construction standards.

[0049] When the lead screw as the adjusting member 3 drives the sliding member 2 to slide, it has high transmission efficiency and can quickly realize the adjustment of the reinforcing steel bar end position. In the construction site, a large number of reinforcing steel bar ends of precast piles usually need to be adjusted, and time is a key factor of efficiency. When the lead screw is rotated, the sliding member 2 will quickly slide in the sliding groove 101. Compared with some traditional manual adjustment methods such as manually pushing and pulling the sliding member, the lead screw driving can adjust the reinforcing steel bar end to the required position in a shorter time. This greatly improves the overall construction efficiency, ensures that the project can be completed on time, and reduces the risk of construction progress lag caused by the delay of the reinforcing steel bar end adjustment process.

[0050] The screw rod is rotatably arranged on the fixed base 1, and the fixed base 1 serves as a support base of the whole tooling and provides a stable rotating environment for the screw rod, thereby ensuring that the adjusting part 3 can continuously and stably drive the sliding part 2 to slide. At the same time, the screw rod and the first threaded hole 202 of the sliding part 2 are tightly and stably matched. The threads of the screw rod and the threads in the first threaded hole 202 are finely processed, and the engagement precision between the two is high, which can effectively prevent slipping and loosening during transmission, ensure reliable power transmission, guarantee the accuracy and stability of the reinforcement end adjustment, and improve the construction safety factor.

[0051] The first threaded hole 202 of the sliding part 2 is not only used for cooperation with the screw rod to realize transmission, but also plays a further fixing role on the reinforcement end. When the reinforcement end is inserted into the fixed cavity 201 of the sliding part 2, the existence of the first threaded hole 202 increases the constraint ability of the sliding part 2 on the reinforcement end, so that the reinforcement is more stable during adjustment and is not easy to shake or deviate. In addition, the screw rod is located in the sliding groove 101, and the design of the sliding groove 101 provides a certain protection for the screw rod and the sliding part 2, preventing external objects such as tools and sundries from colliding with or damaging the screw rod and the sliding part 2 during construction.

[0052] The structure design of the tooling can flexibly adapt to different reinforcement end layouts and specifications in precast piles. Since the screw rod can independently drive each sliding part 2 to slide in the sliding groove 101, whether the reinforcement of the precast pile is distributed in a ring shape, a square shape, or other irregular shapes, the positions of the sliding parts 2 can be adjusted to adapt to different reinforcement end adjustment requirements of different precast piles, thereby improving the versatility and adaptability of the tooling.

[0053] The operation process of the tooling remains simple and intuitive. The construction personnel only need to rotate the screw rod to adjust the position of the reinforcement end, without the need for complex operation skills or professional equipment. For example, at the construction site, the construction personnel can use ordinary wrenches and other tools to rotate the screw rod, gradually adjust the position of the reinforcement end according to the specific requirements of the precast pile and the subsequent construction links such as the connection with the pile cap, and the operation process is simple and easy to implement, which reduces the training cost of the construction personnel and improves the overall work efficiency of the construction team.

[0054] Further, the adjusting part 3 has an extending end 301 extending out of the fixed base 1 from the sliding groove 101, and the extending end 301 has a hexagonal protrusion 302.

[0055] In this embodiment, the extension end 301 of the adjusting member 3 is extended outside the fixed seat 1 by the sliding groove 101, and a hexagonal protrusion 302 is arranged at the extension end 301. This design greatly facilitates the operation of the adjusting member 3 by the construction personnel. On the construction site, the construction personnel usually uses various tools to complete the work tasks. The shape of the hexagonal protrusion 302 perfectly matches the common hexagonal wrench, and the construction personnel only needs to use the hexagonal wrench to clamp the hexagonal protrusion 302 to easily rotate the adjusting member 3, thereby driving the sliding member 2 to slide to adjust the position of the reinforcing bar end. This convenient operation mode enables the construction personnel to quickly move from one precast pile to another precast pile for operation, without the need to frequently change or search for special operation tools, greatly improving the adjustment work efficiency, shortening the adjustment time of the reinforcing bar end of each precast pile, ensuring that the entire precast pile reinforcing bar adjustment process can be efficiently completed, and reducing the risk of construction progress lag caused by the delay of reinforcing bar end adjustment.

[0056] Compared with some other shapes or designs that need special tools to operate, the hexagonal protrusion 302 is more versatile, and the construction personnel can more easily obtain and use the hexagonal wrench on the construction site. Even new employees can quickly get started, familiarize and master this operation mode, reducing the learning cost of the construction personnel for tool operation and improving the overall operation proficiency and work efficiency of the construction team.

[0057] Using the hexagonal wrench to rotate the adjusting member 3 through the hexagonal protrusion 302 can achieve more accurate control of the rotation angle of the adjusting member 3. In building construction, the adjustment of the reinforcing bar end position of the precast pile often needs to be accurate to the millimeter level to ensure accurate connection with the subsequent foundation structure such as the pile cap. By accurately controlling the rotation angle of the adjusting member 3 through the hexagonal wrench, this rotation angle can be accurately converted into the linear sliding displacement of the sliding member 2, thereby achieving precise adjustment of the reinforcing bar end position. For example, when it is necessary to accurately extend the end of a reinforcing bar by 5 millimeters to achieve perfect lapping with the pile cap reinforcing bar, the construction personnel can use the hexagonal wrench to accurately rotate the adjusting member 3 according to the pre-calculated rotation angle of the adjusting member 3, so that the sliding member 2 accurately moves the reinforcing bar end to the specified position with an error controlled within a very small range, effectively ensuring the quality of the connection between the precast pile and the pile cap, and improving the integrity and stability of the building foundation structure.

[0058] The design of the extension end 301 extending to the outside of the fixed seat 1 optimizes the overall structural layout of the tool to some extent. On the construction site, the prefabricated pile steel bar adjustment tool may be disturbed by various external forces, such as vibration of surrounding construction equipment, accidental collision of construction personnel, etc. By setting the extension end 301 on the outside, the construction personnel do not need to approach other components inside the fixed seat 1 during operation, reducing the impact of external forces such as collisions that may occur during operation on the internal structure of the tool such as the sliding piece 2 and the sliding groove 101, ensuring the stability of the internal structure of the tool, ensuring that the steel bar end adjustment work can be carried out in a relatively stable environment, reducing the occurrence of inaccurate steel bar end position adjustment caused by external interference, and improving the reliability and service life of the tool.

[0059] Further, the sliding piece 2 has a second threaded hole 203, and further comprises a conversion joint 4, the conversion joint 4 is threadedly arranged in the second threaded hole 203, the conversion joint 4 comprises a first connecting piece 401, the first connecting piece 401 is threadedly arranged in the second threaded hole 203, the first connecting piece 401 has an inner cavity 402, the inner cavity 402 has an inner tapered guide surface 403, a clamping piece 404 has a tapered surface 405 and a clamping portion 406, the tapered surface 405 is used to abut against the inner tapered guide surface 403, and the clamping portion 406 is clamped with the steel bar, the clamping piece 404 is arranged in a plurality of circumferential rows, and an abutting piece 407 is threadedly arranged on the inner cavity 402, and an end portion of the abutting piece 407 is used to abut against the clamping piece 404.

[0060] In this embodiment, the sliding piece 2 is fixed more accurately and stably to steel bars of different specifications and shapes by being provided with the second threaded hole 203 and cooperating with the design of the conversion joint 4. In building engineering, the specifications of steel bars used in prefabricated piles are various, which may have different diameters, surface textures, etc. The traditional single fixing mode may not be able to meet the fixing needs of all steel bars. The clamping portion 406 of the clamping piece 404 in the conversion joint 4 can be clamped with the steel bar, and this circumferential arrangement of the clamping piece 404 can adapt to steel bars of various shapes, whether round steel bars or special-shaped steel bars with certain edges and corners, and can be effectively fixed by the clamping piece 404. For example, when dealing with some specially designed prefabricated piles that use special-shaped steel bars with protrusions or grooves inside, the clamping portion 406 of the clamping piece 404 can closely fit the special shape of the steel bar, ensuring that the steel bar does not shake or deviate during adjustment, improving the versatility and adaptability of the tool to different types of steel bars.

[0061] The first connecting piece 401 in the conversion joint 4 has an inner cavity 402 provided with an inner tapered guide surface 403, and the clamping piece 404 has a tapered surface 405 corresponding thereto. When the steel bar is inserted into the conversion joint 4, the tapered surface 405 first abuts against the inner tapered guide surface 403, and the cooperation of the tapered surfaces plays a precise guiding role. During the process of inserting the steel bar into the conversion joint 4, different steel bar diameters will push the clamping piece 404 along the tapered surface to different positions, so that the clamping diameter of the clamping piece 404 changes, thereby being able to clamp different diameter steel bars, and even if the insertion angle of the steel bar is slightly deviated, the steel bar can also smoothly enter the correct position under the guidance of the tapered surface, without causing the clamping piece 404 to be deflected, so as to ensure that the clamping part 406 of the clamping piece 404 can accurately clamp the steel bar, thereby improving the accuracy and efficiency of the steel bar fixing.

[0062] Moreover, after the steel bar is inserted and clamped, the abutting piece 407 is threadedly arranged on the inner cavity 402, and the end thereof is used to abut against the clamping piece 404. By tightening the abutting piece 407, pressure can be applied to the clamping piece 404, so that the clamping piece 404 clamps the steel bar more tightly, thereby guaranteeing the position accuracy of the steel bar in the sliding piece 2.

[0063] During the construction process, the state of the prefabricated pile steel bar may need to be flexibly adjusted according to different construction stages or design requirements, such as changing the extension length of the end of the steel bar or adjusting the inclination angle of the steel bar. Through the design of the tooling, the adjustment can be conveniently realized under the cooperation of the sliding piece 2 and the conversion joint 4.

[0064] The conversion joint 4 is threadedly arranged in the second threaded hole 203 of the sliding piece 2, and this threaded connection mode makes the installation and dismounting of the conversion joint 4 very convenient. During daily maintenance or when the conversion joint 4 needs to be replaced, such as being worn or damaged due to long-term use, it can be simply screwed out or screwed in by using a corresponding tool, without the need for complex dismounting and assembling operations.

[0065] Moreover, since the conversion joint 4 is a relatively independent component, the various components inside it, such as the first connecting piece 401, the clamping piece 404 and the abutting piece 407, are also convenient for individual inspection, maintenance and replacement. For example, if it is found that the clamping part 406 of the clamping piece 404 is damaged or deformed, the clamping piece 404 can be individually taken out for repair or replacement, without the need for large-scale disassembly of the entire tooling, thereby further simplifying the maintenance process and improving the maintainability of the tooling.

[0066] The conversion joint 4 is connected with the sliding piece 2 by screwing, which has high connection strength and stability. During long-term construction use, even if the position of the steel bar is frequently adjusted, the steel bar is subjected to its own weight and external forces such as vibration on the construction site, the conversion joint 4 will not easily fall off from the second threaded hole 203 of the sliding piece 2, thereby ensuring the integrity and stability of the tool structure.

[0067] Meanwhile, the abutting piece 407 is screwed on the inner cavity 402 of the first connecting piece 401 inside the conversion joint 4, and the screwing connection also enhances the connection stability between the components. When the abutting piece 407 is screwed to press the clamping piece 404, the components can be tightly matched, and the components will not be loose or disconnected due to pressure changes or external interference, thereby further ensuring the firmness and stability of the steel bar fixation, and enabling the precast pile steel bar to remain stable during the entire adjustment process, thereby providing a strong guarantee for the construction quality.

[0068] Further, the clamping pieces 404 form a clamping cavity 408 for clamping the steel bar.

[0069] In the embodiment, the clamping pieces 404 form the clamping cavity 408, which provides a relatively customized accommodation space for the steel bar. In building engineering, the specifications and shapes of the steel bars used by the precast pile have certain differences, and the clamping cavity 408 can be adaptively adjusted according to the actual situation of different steel bars. For example, for a steel bar with a larger diameter, the clamping pieces 404 will be expanded outward to a certain extent, so that the inner diameter of the clamping cavity 408 is increased to adapt to the size of the steel bar; for a steel bar with a smaller diameter, the clamping pieces 404 will be closer, so that the inner diameter of the clamping cavity 408 is reduced to ensure the tight wrapping of the steel bar. This adaptive adjustment capability enables the steel bar to be accurately and stably fixed in the clamping cavity 408 regardless of the thickness of the steel bar, effectively guarantees the position accuracy of the steel bar during the adjustment process, controls the end position error of the steel bar within a very small range such as ±0.5 millimeters, lays a good foundation for the accurate connection of the precast pile with other structural components such as the pile cap, and improves the integrity and stability of the building foundation structure.

[0070] Meanwhile, the shape of the clamping cavity 408 can also better adapt to the shape characteristics of the steel bar. If the steel bar has a certain curvature or is not a standard circle, the clamping cavity 408 can be fitted to the shape of the steel bar by flexible arrangement and deformation of the clamping pieces 404, avoiding the problems of loose fixation and shaking due to the mismatch between the shape of the steel bar and the fixation space, and further ensuring the firmness and stability of the steel bar fixation.

[0071] The clamping cavity 408 clamps the steel bars from multiple directions through the plurality of clamping pieces 404, forming a full-range fixing mode. Compared with the traditional single-direction fixing, the full-range clamping can more effectively resist external force interference from different directions. The clamping pieces 404 in the clamping cavity 408 tightly clamp the steel bars from all around, so that the steel bars can still remain in a fixed position when subjected to these external forces, without obvious displacement, shaking or loosening phenomenon, greatly enhancing the reliability of the steel bar fixing, ensuring the structural integrity of the precast pile, and reducing the occurrence of precast pile quality problems caused by loose steel bar fixing.

[0072] Further, the abutting piece 407 includes a first abutting piece 409, which is arranged in the inner cavity 402 in a lifting manner and used to abut against the clamping piece 404, and a second abutting piece 410, which is arranged on the inner cavity 402 in a threaded manner, and the elastic piece 411 has one end acting on the first abutting piece 409 and the other end acting on the second abutting piece 410, thereby providing the abutting force of the first abutting piece 409 against the clamping piece 404.

[0073] In this embodiment, the abutting piece 407 provides precise and adjustable abutting force for the clamping of the clamping piece 404 and the steel bar through the combined design of the first abutting piece 409, the second abutting piece 410 and the elastic piece 411. During the process of inserting the steel bar into the clamping cavity 408, the relative position of the clamping piece 404 is likely to change. Through the elastic piece 411 having one end acting on the first abutting piece 409 and the other end acting on the second abutting piece 410, appropriate elastic force can be provided according to the sliding condition of the steel bar, so that the first abutting piece 409 tightly abuts against the clamping piece 404, thereby enabling the first abutting piece 409 to provide a positioning force to the clamping piece 404, and further enabling the clamping piece 404 to achieve precise clamping of the steel bar.

[0074] The first abutting piece 409 is arranged in the inner cavity 402 in a lifting manner and abuts against the clamping piece 404, which makes the abutting process more stable. Compared with some simple rigid abutting methods, the first abutting piece 409 can be self-adaptively adjusted according to the actual position and state of the clamping piece 404 under the action of the elastic piece 411, thereby ensuring that the abutting of the first abutting piece 409 and the clamping piece 404 always remains tight and uniform during the insertion process of the steel bar, so as to avoid the misalignment between the clamping pieces 404 and affect the efficiency.

[0075] Further, the clamping piece 404 has an outer conical guide surface 412 located on one side of the clamping part 406 and used for guiding the insertion of the steel bar into the clamping cavity 408.

[0076] In this embodiment, the outer conical guide surface 412 of the fastener 404 is located on one side of the clamping part 406 and plays an extremely important guiding role when the steel bar is inserted into the clamping cavity 408. In construction engineering, the steel bar in the prefabricated pile needs to be accurately inserted into the clamping cavity 408 for fixation, so as to facilitate subsequent accurate adjustment operation. The conical design of the outer conical guide surface 412 can automatically align the steel bar to the center position during insertion. Even if the initial angle of the steel bar during insertion is slightly deviated, it can still be quickly adjusted in direction under the guidance of the conical surface and smoothly enter the clamping cavity 408. For example, due to limited operation space or inaccurate manual operation in the construction site, the steel bar may not be inserted at a completely vertical angle. However, with the guidance function of the outer conical guide surface 412, the steel bar can still be easily and accurately inserted into the clamping cavity 408, greatly improving the success rate and efficiency of steel bar insertion and reducing the risk of construction delay caused by difficult insertion.

[0077] Further, the first abutting member 409 has a first accommodating groove 413, the second abutting member 410 has a second accommodating groove 414, and the elastic member 411 is configured to be compressed to the shortest, the first abutting member 409 abuts against the second abutting member 410, and the elastic member 411 is located in the first accommodating groove 413 and the second accommodating groove 414.

[0078] In this embodiment, the first abutting member 409 has a first accommodating groove 413, the second abutting member 410 has a second accommodating groove 414, and the elastic member 411 is compressed to the shortest, the first abutting member 409 abuts against the second abutting member 410, and the elastic member 411 is located in the two accommodating grooves. This design cleverly limits the working range of the elastic member 411, so as to accurately control the clamping force of the clamping member 404 during use. When the first abutting member 409 abuts against the second abutting member 410, rotating the second abutting member 410 can make the first abutting member 409 provide stable abutting force to the clamping member 404, thereby ensuring the clamping effect of the clamping member 404 on the steel bar.

[0079] Further, the second abutting member 410 has a conversion threaded hole 415 which is open to the inner cavity 402.

[0080] In this embodiment, the conversion threaded hole 415 of the second abutting member 410 is open to the inner cavity 402, which brings more functional expansion possibilities and flexible adjustment convenience to the tooling. When testing the pull-out force of the steel bar in the prefabricated pile, the conversion threaded hole 415 can be used as an interface to be screw-connected with the pull-out force detection device. This multifunctional conversion and adaptation capability realized through the conversion threaded hole 415 enables the tooling to better meet various complex construction requirements and improves its versatility and practicality.

[0081] The adapter threaded hole 415 also provides a convenient tool access point for the on-site operation of the construction personnel. In the construction site, the construction personnel may need to use various tools to maintain, adjust or monitor the tooling. This convenient tool access greatly simplifies the operation process, reduces the workload of the construction personnel, improves the construction efficiency, and also reduces the risk of damage to the tooling due to improper operation. When the second abutting piece 410 itself needs to be replaced or repaired, the adapter threaded hole 415 can also serve as an auxiliary operation point. The construction personnel can use the adapter threaded hole 415 in cooperation with the corresponding tool, such as a specially designed disassembly tool, to more easily disassemble the second abutting piece 410 from the inner cavity 402, and then perform replacement or repair operations. After that, the new or repaired second abutting piece 410 is reinstalled through the adapter threaded hole 415, and the entire process is simple and fast, improving the maintainability of the tooling and ensuring the continuity of the construction.
