Description

Technical Field

[0001] This utility model relates to a pile splicing tool, specifically an auxiliary tool for splicing square piles. Background Technology

[0002] In the construction of pile foundations for building engineering, prestressed precast square piles are widely used due to their good bearing capacity and ease of construction. These square piles are typically driven into the ground using a pile driver to form a stable pile foundation. During the construction of pile foundations, pile splicing is often required, which involves connecting multiple square piles sequentially to achieve the designed pile length and bearing capacity.

[0003] Traditional methods of square pile joining rely primarily on manual operation. Specifically, construction workers use a pile driver to lift the square piles to be joined, and then place the joint surface of the piles to be joined on the joint surface of the piles already driven into the ground. To ensure a tight connection between the two piles, workers typically use tools such as crowbars and ropes to adjust the joint dimensions.

[0004] Manually adjusting the mating dimensions is not only time-consuming and labor-intensive, but also difficult to guarantee accuracy. Because the mating surfaces of square piles need to be aligned very precisely to ensure the stability and bearing capacity of the pile foundation, even minor deviations in the mating dimensions can lead to quality problems for the entire pile foundation. Traditional mating methods lack effective fixing devices, making them prone to displacement or tilting during the mating process. This not only increases the difficulty and risk of construction but may also adversely affect the safety and stability of the pile foundation. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary tool for splicing square piles, so as to solve the problems of time-consuming and laborious adjustment of the verticality of the upper and lower piles and lack of fixation when splicing piles using existing splicing tools.

[0006] This utility model is implemented as follows: a square pile splicing auxiliary tool, the structure of which includes four corner plates vertically arranged at the four corners, a lower strip plate and an upper strip plate arranged between each two adjacent corner plates, a fine-adjustment mechanism arranged on the upper strip plate, and a fixing mechanism arranged on the lower strip plate; the fixing mechanism is used to fix it to the pile head of the lower pile, and the fine-adjustment mechanism is used to adjust the position of the lower end of the upper pile, and fix the upper pile and the lower pile after they are aligned.

[0007] Furthermore, the fixing mechanism includes a fixing nut fixedly disposed on the outside of the lower strip plate, a fixing bolt passing through the fixing nut and the lower strip plate, a fixing U-shaped plate passing through the fixing bolt, a fixing limiting block fixedly connected to the inner end of the fixing bolt, and a fixing vertical plate attached to the fixing U-shaped plate.

[0008] Furthermore, the fixing U-shaped plate is located on the fixing bolt section inside the lower strip plate.

[0009] Furthermore, a through hole is provided at the bottom of the fixed U-shaped plate for the fixing bolt to pass through, and the open end of the fixed U-shaped plate is fixedly connected to the fixed vertical plate.

[0010] Furthermore, the size of the fixed limiting block is larger than the size of the through hole of the fixed U-shaped plate.

[0011] Furthermore, the fine-tuning mechanism includes a fine-tuning nut fixedly disposed on the outside of the upper strip plate, a fine-tuning bolt passing through the fine-tuning nut and the upper strip plate, a fine-tuning U-shaped plate passing through the fine-tuning bolt, a fine-tuning limiting block fixedly connected to the inner end of the fine-tuning bolt, and a fine-tuning vertical plate connected to the fine-tuning U-shaped plate.

[0012] Furthermore, the lower strip and the upper strip are connected to the corner plate by bolts.

[0013] This invention can precisely adjust the verticality of the upper and lower piles, solving the problems of time-consuming, labor-intensive, and inaccurate manual adjustments in traditional methods. The fine-tuning mechanism makes the adjustment process more intuitive and easier to operate, thereby significantly improving the accuracy and efficiency of pile splicing.

[0014] This invention securely fixes the upper and lower piles, preventing displacement or tilting during the splicing process. This stable fixing method helps ensure the accuracy and safety of the splicing, reducing quality problems caused by unstable splicing.

[0015] This utility model has a reasonable design and compact structure, and is easy to install and disassemble, enabling workers to quickly master its use and improving work efficiency.

[0016] This utility model is applicable to the splicing of square piles of different specifications and sizes. It only requires adjusting the relevant parameters of the fixing mechanism and the fine-tuning mechanism according to actual needs. Attached Figure Description

[0024] like Figure 1 As shown, the present invention is a rectangular frame that is longer and wider than a square pile. It includes four corner plates 3 at the four corners, an upper strip plate 5 and a lower strip plate 4 between each pair of adjacent corner plates 3, a fine-tuning mechanism 7 on the upper strip plate 5, and a fixing mechanism 6 on the lower strip plate 4. The fixing mechanism 6 is used to fix the square pile splicing tool to the pile head of the lower pile 1, and the fine-tuning mechanism 7 is used to adjust the position of the lower end of the upper pile 2, aligning and fixing the upper pile 2 with the lower pile 1.

[0025] All four corner plates 3 are vertically arranged, with the inner corner of each corner plate 3 facing the outer corner of the square pile. Upper strip plates 5 and lower strip plates 4 are horizontally arranged on the front, back, left, and right sides of this utility model. No strip plates are provided on the top and bottom sides to facilitate the passage of the square pile. The upper strip plates 5 and lower strip plates 4 on each side are spaced apart, with the spacing facilitating observation of whether the upper pile 2 and lower pile 1 are aligned, and also facilitating welding of the mating surfaces of the upper pile 2 and lower pile 1 through this gap.

[0026] The inner side of the upper strip 5 and the inner side of the lower strip 4 on each side are connected to one outer side of the two corner plates 3. The upper strip 5 and the lower strip 4 on the four sides are at the same height to more evenly bear the force in all directions, thereby avoiding stress concentration and deformation problems caused by height differences.

[0027] The connection between the lower strip plate 4 and the upper strip plate 5 and the corner plate 3 can be welded, detachable, or at least one side can be detachable, such as by bolts (not shown). When welded, the square pile splicing auxiliary tool is not removed after one splicing operation; it is removed from the upper end of the pile 2 after the splicing is complete. When detachable, one side of the lower strip plate 4 and upper strip plate 5 can be removed after one splicing operation, and then the square pile splicing auxiliary tool can be removed. In this embodiment, both the lower strip plate 4 and upper strip plate 5 are corner plates; they can also be square tubes, etc.

[0028] like Figure 2As shown, the fixing mechanism 6 and the fine-tuning mechanism 7 have the same structure. The fixing mechanism 6 includes a fixing nut 61 fixedly disposed on the outside of the lower strip plate 4, a fixing bolt 62 passing through the fixing nut 61 and the lower strip plate 4, a fixing U-shaped plate 63 passing through the fixing bolt 62, a fixing limiting block 64 fixedly connected to the inner end of the fixing bolt 62, and a fixing vertical plate 65 connected to the fixing U-shaped plate 63. The fixing U-shaped plate 63 is located on the fixing bolt 62 section on the inner side of the lower strip plate 4. A hole is opened at the bottom of the fixing U-shaped plate 63 for the fixing bolt 62 to pass through. The fixing bolt 62 passes through the bottom of the fixing U-shaped plate 63. The open end of the fixing U-shaped plate 63 is fixedly connected to one side of the fixing vertical plate 65. The size of the fixing limiting block 64 is larger than the size of the through hole of the fixing U-shaped plate 63 to prevent the fixing limiting block 64 from falling out of the fixing U-shaped plate. The bottom of the fixing U-shaped plate 63 and the fixing vertical plate 65 restrict the fixing limiting block 64 in the fixing U-shaped plate 63. The vertical fixing plate 65 is set vertically, parallel to one side of the square pile. The bolt head of the fixing bolt 62 is on the outside of the lower strip plate 4, so that the position of the fixing plate 65 can be adjusted by means of the bolt head. The fixing nut 61 is set in the middle of the lower strip plate 4.

[0029] like Figure 3 As shown, the fine-tuning mechanism 7 includes a fine-tuning nut 71 fixedly disposed on the outside of the upper strip plate 5, a fine-tuning bolt 72 passing through the fine-tuning nut 71 and the upper strip plate 5, a fine-tuning U-shaped plate 73 passing through the fine-tuning bolt 72, a fine-tuning limiting block 74 fixedly connected to the inner end of the fine-tuning bolt 72, and a fine-tuning vertical plate 75 connected to the fine-tuning U-shaped plate 73. In this embodiment, both the fixed limiting block 64 and the fine-tuning limiting block 74 are nuts welded to the inner ends of the corresponding bolts.

[0030] Each side of the square pile splicing auxiliary tool has two lower strip plates 4 and two fixing mechanisms 6 to better fix the square pile splicing auxiliary tool to the lower pile 1.

[0031] The pile splicing method using square pile splicing auxiliary tools includes the following steps:

[0032] S1. Fix the lower part of the square pile splicing auxiliary tool to the upper end of the lower pile 1, such as... Figure 4 As shown, the lower part of the square pile splicing auxiliary tool is placed on the upper end of the lower pile 1 that has been driven into the ground. Then, the tool is used to rotate the fixing bolt 62 of the lower part of the square pile splicing auxiliary tool so that the four fixing vertical plates 65 of the lower part are all pressed against the four sides of the lower pile 1.

[0033] S2. Hoist the lower end of the upper pile 2 into the upper part of the square pile splicing auxiliary tool, such as... Figure 5 As shown, the upper pile 2 is lifted by a pile driver, and the lower end of the upper pile 2 is inserted vertically downwards into the square pile splicing auxiliary tool until the lower end face of the upper pile 2 is in close contact with the upper end face of the lower pile 1; at this time, the upper pile 2 and the lower pile 1 are not aligned in terms of verticality.

[0034] S3. Fine-tune the upper pile 2 using the fine-tuning mechanism 7 on the upper part of the square pile splicing auxiliary tool, such as... Figure 6 As shown, adjust the upper fine-tuning bolt 72, and push the upper pile 2 through the corresponding fine-tuning vertical plate 72 to align the verticality of the upper pile 2 with that of the lower pile 1; after the upper pile 2 and the lower pile 1 are aligned vertically, tighten all the fine-tuning bolts 72 of the upper fine-tuning mechanism 7 to fix the upper pile 2 and the lower pile 1.

[0035] S4. Weld the lower end of the upper pile 2 to the contact part of the lower pile 2. After welding, loosen all the fine adjustment bolts 62 and 72 of the fixing mechanism 6 and the fine adjustment mechanism 7. Place a baffle on the ground near the lower pile to prevent the square pile splicing auxiliary tool from being driven into the ground during pile driving. Or, if the lower strip plate 4 and the upper strip plate 5 are detachably connected to the corner plate 3, remove one side of the lower strip plate 4 and the upper strip plate 5 and remove the square pile splicing tool from the upper pile 2.

[0036] S5. Drive most of the upper pile 2 into the ground using a pile driver, leaving the pile head for splicing. At this point, the upper pile 2 becomes the lower pile 1.

[0037] S6. Repeat steps S1-S5 until the piles are driven to the design elevation, then remove the pile splicing auxiliary tools.
