Description

Technical Field

[0001] The utility model relates to the technical field of building pile foundations, in particular to a pile foundation displacement auxiliary detection mechanism for building pile foundations. Background Technique

[0002] Building pile foundations are one of the commonly used foundation forms in construction projects, used to support the weight of buildings and transfer it to the underground soil. They are usually composed of concrete, steel bars or precast piles. In order to help engineers monitor the possible displacement of building pile foundations during use in real time to ensure the safety and stability of buildings, a pile foundation displacement auxiliary detection device is used to detect the pile foundation, so as to adjust the skewed pile foundation. When detecting the tilt angle of the device, an angle measuring device is used to measure the angle between the vertical direction and the pile foundation, so as to judge the skewness of the pile foundation.

[0003] After retrieval, the utility model with the publication number of "CN216515776U" provides "a pile foundation displacement auxiliary detection device for building engineering technology, including a column. A contact plate is fixedly connected to the lower end of the column. A bearing fixedly connected to the column is arranged on the upper end of the contact plate. A threaded sleeve is fixedly connected to the inner shaft surface of the bearing. The end of the threaded sleeve away from the column is flush with the contact plate. A connecting column is connected in the threaded sleeve in a threaded manner. A bubble level is fixedly connected to the upper end of the column. The utility model has the advantages of reducing the error during measurement and ensuring the accuracy of the measurement result". However, when the detection environment ground is a cement floor or a relatively hard floor, the insertion end of its column cannot be inserted, resulting in the inability to fix the column. Secondly, the tilted angle cannot be directly seen with the naked eye. It is necessary to measure the distance that the connecting column extends out of the threaded sleeve with a ruler, calculate the tan value of the tilt angle according to the ratio, and then use a computer to calculate the tilted angle according to the tan value. Its calculation method is extremely cumbersome, time-consuming and laborious, and is easily affected by manual calculation errors.

Specific implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-5 As shown, the present invention provides an implementation mode: a pile displacement auxiliary detection mechanism for building pile foundations, including a support sleeve 1, a vertical plate 6 and a detection plate 8. A pointed head 11 is provided at the lower end of the support sleeve 1. A connecting cylinder 2 is movably connected below the support sleeve 1. The lower end of the connecting cylinder 2 is rotatably connected to a base plate 3. An inner rod 4 is slidably installed inside the support sleeve 1. The upper end of the inner rod 4 is welded to a connecting rod 5. The upper end of the connecting rod 5 is fixedly installed with a bubble level 51. A support plate 14 is welded to one side of the support sleeve 1. The upper end of the support plate 14 is welded to the vertical plate 6, and one side of the upper end of the vertical plate 6 is welded to one side of the connecting rod 5. A threaded hole 52 is formed through the side surface of the connecting rod 5. An adjusting rod 7 is threadedly installed inside the threaded hole 52. The end of the adjusting rod 7 away from the connecting rod 5 is rotatably installed with a detection plate 8. The lower end of the detection plate 8 is rotatably installed at one end of the support plate 14;

[0026] The detection plate 8 is composed of a lower plate 81 and an upper plate 82. Fixing buckles 15 are welded to the upper end of the support plate 14 and on one side of the vertical plate 6. First rotating shafts 811 are welded to both sides of the lower end of the lower plate 81, and the first rotating shafts 811 are rotatably installed inside the fixing buckles 15. The upper plate 82 is slidably installed on the outer side of the upper end of the lower plate 81. Second rotating shafts 821 are welded to both sides of the upper end of the upper plate 82.

[0027] Further, a thread buckle 12 is provided on the outer side of the lower end of the support sleeve 1, and the connecting cylinder 2 is threadedly sleeved on the outer side of the thread buckle 12. A threaded structure is adopted between the support sleeve 1 and the connecting cylinder 2, which is convenient for the disassembly and assembly of the connecting cylinder 2.

[0028] Further, a locking bolt 13 is threadedly installed on the other side of the support sleeve 1, and the end of the locking bolt 13 penetrates through the support sleeve 1 and abuts against the outer side of the inner rod 4. The detectable height range can be adjusted according to the height of the pile foundation to be detected. By changing the height of the inner rod 4 extending out of the support sleeve 1, the vertical plate 6 and the detection plate 8 are synchronously increased. After the adjustment is completed, the position of the inner rod 4 is fixed by abutting the inner rod 4 with the locking bolt 13.

[0029] Further, a connecting seat 21 is welded to the lower end of the connecting cylinder 2. Shaft rods 22 are welded to both sides of the connecting seat 21. Right-angle seats 31 are welded to both sides of the upper surface of the base plate 3. A rotating hole 311 is penetrated through the side surface of the right-angle seat 31, and the shaft rod 22 is rotatably installed inside the rotating hole 311. The connecting cylinder 2 and the base plate 3 are in a state where the angle can be adjusted. When the detection position is inclined and the base plate 3 is placed obliquely, the inclination angle between the connecting cylinder 2 and the base plate 3 can be changed to keep the connecting cylinder 2 always in a relatively vertical state.

[0030] Further, a threaded short rod 23 is welded on one side of the connecting seat 21 and above the shaft rod 22. An arc-shaped groove 312 is penetrated through the side surface of one group of right-angle seats 31 and above the rotating hole 311, and the threaded short rod 23 is slidably installed inside the arc-shaped groove 312. A nut 24 is threadedly sleeved on the outer side of the threaded short rod 23, and one side of the nut 24 abuts against the outer side of the right-angle seat 31. Fixing grooves 32 are penetrated through the periphery of the base plate 3. When adjusting the inclination angle between the connecting cylinder 2 and the base plate 3, the connecting seat 21 drives the threaded short rod 23 to slide inside the arc-shaped groove 312. After the adjustment is completed, the position of the adjusted connecting cylinder 2 is fixed by abutting the nut 24 against the right-angle seat 31.

[0031] Further, a knob 71 is welded to one end of the adjusting rod 7, and a fixing seat 72 is rotatably installed at the other end of the adjusting rod 7. A connecting buckle 73 is welded to the lower end of the fixing seat 72, and the rotating shaft two 821 is rotatably installed inside the connecting buckle 73. Manually rotate the knob 71, and the knob 71 drives the adjusting rod 7 to rotate inside the threaded hole 52, thereby driving the fixing seat 72 to move to one side.

[0032] Furthermore, the vertical plate 6 includes a fixed rod 61 and a sliding frame 62. The fixed rod 61 is welded to the upper end of the support plate 14. The sliding frame 62 is slidably mounted on the outer side of the upper end of the fixed rod 61. A connecting plate 63 is welded to the upper end of the sliding frame 62, and the other end of the connecting plate 63 is welded to one side of the connecting rod 5. The vertical plate 6 can remain parallel to the support sleeve 1. When the height of the inner rod 4 is adjusted, the vertical plate 6 also makes a corresponding length change to adapt to the changed height difference after adjustment. When the height of the inner rod 4 is adjusted, the connecting rod 5 drives the sliding frame 62 to slide on the outer side of the fixed rod 61 through the connecting plate 63.

[0033] Furthermore, sliders 812 are welded to both sides of the upper end of the lower plate 81. Sliding grooves 822 are formed through both sides of the upper plate 82, and the sliders 812 are slidably mounted inside the sliding grooves 822. When the adjusting rod 7 drives the fixed seat 72 to move, the fixed seat 72 indirectly drives the upper plate 82 to move synchronously to one side. While the upper plate 82 is moving, the upper plate 82 and the lower plate 81 slide relative to each other, increasing their lengths to adapt to the angle change between the detection plate 8 and the vertical plate 6.

[0034] Working principle: First, move a pile foundation displacement auxiliary detection mechanism for building pile foundations to the working position. In the first step, during detection, the pointed head 11 or the base plate 3 can be selected according to the actual environment. When the detection environment is soil or other easily insertable ground, the pointed head 11 can be directly inserted into the ground. When the detection environment is a cement floor or other non-easily insertable ground, the base plate 3 can be used for fixing. In the second step, when using the base plate 3 for fixing, first make one end of the support plate 14 fit against the pile foundation, and then the inclination angle between the support sleeve 1 and the base plate 3 can be adjusted according to the inclination degree of the ground. Observe the bubble level 51 to determine whether the support sleeve 1 is in a vertical state. After adjustment, tighten the nut 24 and make it abut against the outside of the right-angle seat 31. In the third step, adjust the length of the inner rod 4 extending out of the support sleeve 1 according to the height of the pile foundation. After adjustment, tighten the locking bolt 13 and make it abut against one side of the inner rod 4. In the fourth step, if the upper end of the pile foundation is also in a fitting state with the fixed seat 72, it means that the pile foundation is in a vertical state at this time. If the upper end of the pile foundation is not in a fitting state with the fixed seat 72, the knob 71 can be manually rotated at this time. While the knob 71 drives the adjusting rod 7 to rotate inside the threaded hole 52, it drives the fixed seat 72 to move closer to the pile foundation side until the detection plate 8 fits against the pile foundation. At this time, the inclination state of the pile foundation can be judged by the included angle between the detection plate 8 and the vertical plate 6, and then use an angle measuring instrument to measure the included angle between the detection plate 8 and the vertical plate 6. In this way, the use process of a pile foundation displacement auxiliary detection mechanism for building pile foundations is completed.
