Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a building test pile structure. Background Technology

[0002] With the acceleration of urbanization and the continuous advancement of construction technology, high-rise and super high-rise buildings, as well as large-scale infrastructure projects, are increasing, placing higher demands on the bearing capacity and stability of pile foundations. Accurately understanding the performance of piles under stress is crucial for optimizing pile foundation design and ensuring the safety of building structures. As a key step in obtaining pile performance data, pile testing is becoming increasingly important. Pile testing provides a scientific basis for the design and construction of pile foundations, avoiding safety accidents caused by unreasonable foundation design, and also helps improve the economic and social benefits of construction projects.

[0003] Existing technologies mainly involve building large-scale measurement frames, which are typically assembled on-site from standard-sized metal pipes or steel profiles. The joints are rigidly connected by flanges, high-strength bolts, pins, or welding. This requires complex assembly and fixing operations on-site. After the frame is erected, high-precision optical measuring equipment is installed on it to determine the displacement of the pile by measuring the positional changes of specific marker points on the pile.

[0004] The construction and installation of large-scale measurement frames, as described above, are extremely complex, involving the assembly and debugging of multiple precision components and requiring substantial human and material resources. During installation, the large weight of the components and the high precision requirements for positioning make them susceptible to errors due to foundation settlement or human negligence. These errors directly affect the accuracy of the final measurement, leading to data deviations. Utility Model Content

[0005] To improve the accuracy of pile testing, this application provides a building pile structure.

[0006] This application provides a building test pile structure, which adopts the following technical solution: A test pile structure for construction includes a steel pipe with supports at both ends. The supports support the steel pipe, and a positioning element is provided at one end of the steel pipe. The steel pipe is inserted into the positioning element, and the positioning element is slidably connected to the steel pipe along its length. A fixing rod is fixedly provided on one side of the positioning element, and a displacement needle is provided at the end of the fixing rod away from the positioning element. The displacement needle is detachably connected to the fixing rod, and a detection device is connected to one end of the displacement needle to measure the displacement of the displacement gauge.

[0007] By adopting the above technical solution, the bracket supports the steel pipe. One end of the steel pipe forms a complete detection link with the displacement needle and detection equipment through the positioning component. When the steel pipe is displaced, the positioning component moves synchronously with the steel pipe, thereby causing the fixed rod and displacement needle to change position. The detection equipment can directly capture the displacement data of the displacement needle. The displacement needle and the fixed rod are detachably connected. When the displacement needle malfunctions, there is no need to disassemble the entire positioning component and fixed rod structure, reducing maintenance difficulty. The sliding connection between the positioning component and the steel pipe enables the detection of displacement at different positions of the steel pipe, reducing the probability of measurement errors and improving the accuracy of the device.

[0008] Optionally, the support includes a first connecting rod, a second connecting rod, and a telescopic rod. The first connecting rod and the second connecting rod are located at the lower end of the steel pipe. The first connecting rod and the second connecting rod are arranged crosswise and are rotatably connected. The telescopic rod is fixed between the first connecting rod and the second connecting rod and can be extended and retracted.

[0009] By adopting the above technical solution, the telescopic function of the telescopic rod and the cross-rotation structure of connecting rod one and connecting rod two form a linkage mechanism. When the telescopic rod extends, its two ends push the cross connecting rod one and connecting rod two to unfold around the rotation axis, and the support height of the support for the steel pipe increases accordingly. When the telescopic rod shortens, the cross angle of connecting rod one and connecting rod two decreases under the action of contraction force, and the support height decreases synchronously. When there are slight bumps or depressions on the ground, the support height on one side of the support can be changed by adjusting the telescopic rod's extension amount, so that the steel pipe remains horizontal and the flexibility of use is improved.

[0010] Optionally, the telescopic rod includes an inner rod and an outer rod. The inner rod is fixed to one side of the first connecting rod, and the outer rod is fixed to one side of the second connecting rod. The inner rod is inserted into the outer rod and is slidably connected to the outer rod along the length of the outer rod. The outer rod has several connecting holes along the transverse direction. One side of the outer rod is provided with an insert rod, which passes through any connecting hole and is threadedly connected to the inner rod.

[0011] By adopting the above technical solution, the several connecting holes opened along the transverse direction of the outer rod form a graded adjustment position. When the inner rod is inserted into the outer rod, the support height of the bracket can be adjusted by selecting the connecting holes at different positions for fixation. When the telescopic rod is subjected to vertical load or transverse force, the insertion rod can be limited to reduce the relative sliding between the inner rod and the outer rod. The threaded connection can reduce the probability of the insertion rod loosening under vibration, impact and other working conditions, and improve the stability of the device.

[0012] Optionally, the positioning components include an upper clamping block and a lower clamping block. The upper clamping block is located at the upper end of the steel pipe, and the lower clamping block is located at the lower end of the steel pipe. The fixing rod is fixed to one side of the lower clamping plate, and the upper clamping block is located at the lower end of the lower clamping block. The upper clamping block and the lower clamping block are detachably connected, and a cavity is formed between the upper clamping block and the lower clamping block, with the steel pipe located inside the cavity.

[0013] By adopting the above technical solution, the cavity formed by the combination of the upper and lower clamping blocks can achieve full-circumferential clamping of the steel pipe. When the steel pipe is displaced, the positioning component can be displaced synchronously through the tightly fitting contact surface, ensuring that the displacement signal is transmitted to the displacement needle.

[0014] Optionally, the upper clamping plate is provided with a number of ball bearings at one end near the steel pipe. The ball bearings are evenly distributed in the transverse direction and are in rolling connection with the upper clamping plate.

[0015] By adopting the above technical solution, when the steel pipe slides along its length, the ball bearings can transform sliding friction into rolling friction, reducing the friction between the steel pipe and the upper clamping block, making the steel pipe slide more smoothly, and improving the flexibility of the device.

[0016] Optionally, the lower clamping block is provided with two threaded rods on the side near the upper clamping block. The two threaded rods are located at both ends of the lower clamping block. The upper clamping block has through holes corresponding to the threaded rods. A nut is provided at the end of the threaded rod away from the lower clamping block. The threaded rod passes through the through hole and is threadedly connected to the nut in the upper clamping block.

[0017] By adopting the above technical solution, the two threaded rods are located at both ends of the lower clamping block, forming symmetrically distributed fastening fulcrums. When tightening the nut, the upper clamping block is pressed down evenly under the action of symmetrical axial forces at both ends, so that the inner wall of the cavity forms a uniform contact with the surface of the steel pipe around the entire circumference, realizing the detachable connection between the upper and lower clamping blocks. This facilitates the installation and removal of the positioning component, and the connection method is stable and reliable, ensuring the connection effect between the positioning component and the steel pipe.

[0018] Optionally, a number of positioning blocks are provided on the side of the upper clamping block near the lower clamping block. The positioning blocks are evenly distributed around the circumference of the upper clamping block and are slidably connected to the upper clamping block in the vertical direction. A positioning rod is fixed on one side of the positioning block. A number of grooves are opened in the upper clamping plate in the vertical direction. An elastic element is provided between the positioning block and the upper clamping plate. In the natural state of the elastic element, the positioning rod is inserted into any groove and is engaged with the inner wall of the groove.

[0019] By adopting the above technical solution, the positioning block slides horizontally, at which point the elastic element is compressed, causing the positioning rod to separate from the groove. The positioning block slides vertically, adjusting its position and thus changing the distance between the upper and lower clamping blocks. This adapts to steel pipes of different sizes, improving the flexibility of the device. After adjustment, the elastic element resets, driving the positioning rod to move and engage with the inner wall of the corresponding groove, reducing the probability of accidental sliding of the positioning block and improving the stability of the device.

[0020] Optionally, a connecting ring is fixed to the upper end of the displacement needle, a fixing rod passes through the connecting ring, and a screw is provided on one side of the connecting ring. The screw passes through the connecting ring and is threadedly connected to the fixing rod.

[0021] By adopting the above technical solution, the fixing rod passes through the connecting ring and is connected with screws, realizing the detachable connection between the displacement pin and the fixing rod. This facilitates the installation and removal of the displacement pin, makes subsequent maintenance and replacement of the displacement pin easier, and improves the convenience of using the device.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. One end of the steel pipe forms a complete detection link with the positioning component, displacement needle, and detection equipment. When the steel pipe is displaced, the positioning component moves synchronously with the steel pipe, thereby causing the fixed rod and displacement needle to change position. The detection equipment can directly capture the displacement data of the displacement needle. The sliding connection between the positioning component and the steel pipe enables the detection of the displacement of the steel pipe at different positions, reducing the probability of measurement errors and improving the accuracy of the device. 2. Slide the positioning block laterally. At this time, the elastic element is compressed, causing the positioning rod to separate from the groove. Slide the positioning block vertically to adjust the position of the positioning block, thereby changing the distance between the upper clamping block and the lower clamping block, adapting to steel pipes of different sizes and improving the flexibility of the device. 3. The fixing rod passes through the connecting ring and is connected with screws, realizing a detachable connection between the displacement pin and the fixing rod. This facilitates the installation and removal of the displacement pin, makes subsequent maintenance and replacement of the displacement pin easier, and improves the convenience of using the device.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] This application discloses a building test pile structure. Example

[0031] Reference Figure 1 and Figure 2 A test pile structure includes a steel pipe 1, with supports 12 at both ends of the steel pipe 1. The supports 12 are placed on the ground. During testing, both ends of the steel pipe 1 are placed on the two supports 12 respectively. Each support 12 includes a connecting rod 121, a connecting rod 122, and a telescopic rod 123. The connecting rods 121 and 122 are located at the lower end of the steel pipe 1, and are arranged crosswise and rotatably connected. The telescopic rod 123 is fixed between the connecting rods 121 and 122, and is telescopically extendable. The telescopic function of the telescopic rod 123 is similar to that of the connecting rods 121 and 122. The cross-rotation structure of connecting rod 121 and connecting rod 122 forms a linkage mechanism. When the telescopic rod 123 extends, its two ends push the cross connecting rod 121 and connecting rod 122 to unfold around the rotation axis, and the support height of the bracket 12 on the steel pipe 1 increases accordingly. When the telescopic rod 123 shortens, the cross angle of connecting rod 121 and connecting rod 122 decreases under the action of contraction force, and the support height decreases synchronously. When there are small bumps or depressions on the ground, the support height on one side of the bracket 12 can be changed by adjusting the extension amount of the telescopic rod 123, so that the steel pipe 1 remains horizontal and the flexibility of use is improved.

[0032] Reference Figure 1 and Figure 2 The telescopic rod 123 includes an inner rod 1231 and an outer rod 1232. The inner rod 1231 is fixed to one side of the connecting rod 121, and the outer rod 1232 is fixed to one side of the connecting rod 122. The inner rod 1231 is inserted into the outer rod 1232, and the inner rod 1231 is slidably connected to the outer rod 1232 along the length of the outer rod 1232. When the height of the bracket 12 is adjusted, sliding the inner rod 1231 changes the distance between the inner rod 1231 and the outer rod 1232, thereby changing the length of the telescopic rod 123, which can realize the adjustment of the height of the bracket 12. 2. Adjustment of support height: The outer rod 1232 has several connecting holes along the transverse direction. A plug rod 1233 is provided on one side of the outer rod 1232. After adjustment, the plug rod 1233 passes through any connecting hole and is threadedly connected to the inner rod 1231. When the telescopic rod 123 is subjected to vertical load or transverse force, the plug rod 1233 can be limited to reduce the relative sliding between the inner rod 1231 and the outer rod 1232. The threaded connection can reduce the probability of the plug rod 1233 becoming loose under vibration, impact and other working conditions, and improve the stability of the device.

[0033] Reference Figure 3One end of the steel pipe 1 is provided with a positioning element 11, which includes an upper clamping block 111 and a lower clamping block 112. The upper clamping block 111 is located at the upper end of the steel pipe 1, and the lower clamping block 112 is located at the lower end of the steel pipe 1. A fixing rod 13 is fixed to one side of the lower clamping plate, with the upper clamping block 111 located at the lower end of the lower clamping block 112. The upper clamping block 111 and the lower clamping block 112 are detachably connected, forming a cavity between the upper clamping block 111 and the lower clamping block 112. The steel pipe 1 is located in the cavity, thereby achieving positioning of the steel pipe. The 1-way full-circumference clamping is provided with a fixing rod 13 fixed on one side of the lower clamping block 112. The end of the fixing rod 13 away from the positioning member 11 is provided with a displacement needle 14. The displacement needle 14 is detachably connected to the fixing rod 13. One end of the displacement needle 14 is connected to a detection device 15. When the steel pipe 1 is displaced, the positioning member 11 moves synchronously with the steel pipe 1, thereby causing the fixing rod 13 and the displacement needle 14 to change position. The detection device 15 can directly capture the displacement data of the displacement needle 14.

[0034] Reference Figure 3 and Figure 4 The positioning component 11 is slidably connected to the steel pipe 1 along its length. The sliding positioning component 11 changes the position of the displacement needle 14, enabling the detection of displacement at different positions of the steel pipe 1, reducing the probability of measurement errors and improving the accuracy of the device. Several ball bearings 1121 are provided at one end of the upper clamping plate near the steel pipe 1. These ball bearings 1121 are evenly distributed laterally and are slidably connected to the upper clamping plate. When the steel pipe 1 slides along its length, the ball bearings 1121 convert sliding friction into rolling friction, reducing the friction between the steel pipe 1 and the upper clamping block 111, making the sliding of the steel pipe 1 smoother and improving the flexibility of the device.

[0035] Reference Figure 3 The lower clamping block 112 has two threaded rods 113 on the side near the upper clamping block 111. The two threaded rods 113 are located at both ends of the lower clamping block 112. The upper clamping block 111 has through holes corresponding to the threaded rods 113. The end of the threaded rod 113 away from the lower clamping block 112 is provided with a nut 114. The threaded rod 113 passes through the through hole and is threadedly connected to the nut 114. When the nut 114 is tightened, the upper clamping block 111 is pressed down evenly under the action of symmetrical axial forces at both ends, so that the inner wall of the cavity forms a uniform contact with the surface of the steel pipe 1 around the circumference. This realizes the detachable connection between the upper clamping block 111 and the lower clamping block 112, which facilitates the installation and removal of the positioning component 11. The connection method is stable and reliable, which can ensure the connection effect between the positioning component 11 and the steel pipe 1.

[0036] Reference Figure 4 and Figure 5The upper clamping block 111 has several positioning blocks 1111 on one side near the lower clamping block 112. These positioning blocks 1111 are evenly distributed circumferentially around the upper clamping block 111 and are slidably connected vertically to it. A positioning rod 1112 is fixedly mounted on one side of each positioning block 1111. The upper clamping plate has several grooves 1114 vertically. The positioning rod 1112 is inserted into any of the grooves 1114 and engages with the inner wall of the groove 1114. An elastic element 1113 is provided between the positioning block 1111 and the upper clamping plate. The elastic element 1113 can be a spring. When it is necessary to adjust the position of the upper clamping block 111 and the lower clamping block 112... When the distance is 12, slide the positioning block 1111 laterally. At this time, the elastic element 1113 is compressed, causing the positioning rod 1112 to separate from the groove 1114. Slide the positioning block 1111 vertically to adjust the position of the positioning block 1111, thereby changing the distance between the upper clamping block 111 and the lower clamping block 112 to adapt to steel pipes 1 of different sizes, improving the flexibility of the device. After the adjustment is completed, the elastic element 1113 resets and drives the positioning rod 1112 to move, so that the positioning rod 1112 engages with the inner wall of the corresponding groove 1114, reducing the probability of the positioning block 1111 sliding accidentally and improving the stability of the device.

[0037] Reference Figure 3 A connecting ring 141 is fixedly provided at the upper end of the displacement pin 14. The fixing rod 13 passes through the connecting ring 141. A screw 142 is provided on one side of the connecting ring 141. The screw 142 passes through the connecting ring 141 and is threadedly connected to the fixing rod 13. When the displacement pin 14 needs to be replaced, the screw 142 is rotated to separate the screw 142 from the fixing rod 13. The connecting ring 141 is slid to remove the connecting ring 141 from the fixing rod 13, so that the displacement pin 14 is separated from the fixing rod 13. This facilitates the installation and removal of the displacement pin 14, and makes it convenient for subsequent maintenance and replacement of the displacement pin 14, thus improving the ease of use of the device.

[0038] The implementation principle of a test pile structure in this application embodiment is as follows: the two ends of the steel pipe 1 are placed on two supports 12 respectively, and the nuts 114 are tightened to clamp the steel pipe 1 with the positioning component 11. When the steel pipe 1 is displaced, the positioning component 11 is displaced synchronously with the steel pipe 1, thereby causing the fixed rod 13 and the displacement needle 14 to change position. The detection device 15 can directly capture the displacement data of the displacement needle 14 and slide the positioning component 11 laterally to detect the displacement of the steel pipe 1 at different positions, reduce the probability of measurement errors, and improve the accuracy of the device.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
