Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a pile connection structure for building construction. Background Technology
[0002] Pile splicing refers to the process of connecting precast piles one by one to continue driving them down to the designed depth because the length of a single pile is insufficient. The process of connecting the top of the previous pile to the bottom of the next pile is called pile splicing. During the pile splicing process, usually the bottom of a pile has been driven vertically into the underground soil layer, while the top is exposed.
[0003] A current type of pile splicing structure for construction, as described in patent publication number CN217150203U, comprises: a first splicing plate and a second splicing plate. The cross-sections of the first and second splicing plates are larger than the cross-section of the pile. The first and second splicing plates are respectively fixedly connected to the opposite ends of two piles. The upper surface of the first splicing plate is in contact with the lower surface of the second splicing plate. A positioning component for constraining the relative horizontal displacement of the first and second splicing plates is provided between the upper surface of the first splicing plate and the lower surface of the second splicing plate. This application has the effect of facilitating pile splicing.
[0004] Regarding the aforementioned related technologies, the applicant discovered that a pile splicing structure for construction guides and connects the first and second piles through the cooperation of guide columns and guide holes. However, since multiple guide columns and guide holes are provided, misalignment between the guide columns and guide holes during the connection of the first and second pile splicing plates directly leads to connection failure, increasing the engineering difficulty of connecting the first and second piles and thus reducing the efficiency of pile splicing. Therefore, we propose a pile splicing structure for construction. Utility Model Content

[0033] The following is in conjunction with the appendix Figure 1-6The present invention will be described in further detail below.
[0034] Please see Figures 1-4 The diagram illustrates a pile connection structure for construction, comprising a first pile body 1 and a second pile body 2, which are in contact with each other. A guide assembly 3 is installed between the first pile body 1 and the second pile body 2. The guide assembly 3 includes two guide rods 301 symmetrically distributed. The top of the first pile body 1 has a recessed groove 3011 for sliding the guide rods 301, and the bottom of the second pile body 2 has a positioning groove 302 for inserting the guide rods 301. One end of the guide rod 301 is T-shaped, and the other end is conical, causing the bottom of the positioning groove 302 to... The radius of the guide rod 301 is larger than the radius of the top of the positioning groove 302, which is more conducive to the quick insertion of the guide rod 301 into the positioning groove 302. The gap between the guide rod 301 and the positioning groove 302 is 0.2-0.5MM. A compression spring 303 is elastically connected between the guide rod 301 and the hidden groove 3011. The elastic coefficient of the compression spring 303 is 5-8N / mm, and the free length is 50mm. The first pile body 1 and the second pile body 2 are fixed by a fixing component 4. The fixing component 4 includes two bolts 401, which are symmetrical. The structure is arranged such that the second pile body 2 and the guide assembly 3 are positioned at a 90-degree angle. A positioning block 4011 is fixed to the outer wall of the bolt 401. The bottom of the positioning block 4011 is arc-shaped. The bolt 401 is threadedly connected to the first pile body 1 and the second pile body 2. A limit groove 402 is formed at the top of the second pile body 2 near the bolt 401. A limit rod 4021 is slidably connected inside the limit groove 402. The bottom of the limit rod 4021 is T-shaped, which can limit the position of the limit rod 4021. A top block 4022 is fixed to one end of the limit rod 4021. One end of the bolt 401 passes through the interior of the top block 4022 and is slidably connected to the top block 4022. The bottom of the positioning block 4011 is adapted to the top arc surface of the top block 4022. An annular groove 403 is provided at the top of the second pile body 2 near the limiting groove 402. A strong spring 404 is provided inside the annular groove 403. The strong spring 404 is made of 60Si2MnA material and has a preload of 10-15mm. One end of the strong spring 404 is fixedly connected to the bottom of the annular groove 403, and the other end of the strong spring 404 is fixedly connected to the bottom of the top block 4022.
[0035] When connecting the first pile 1 and the second pile 2, after the second pile 2 is lifted, the top of the first pile 1 contacts the bottom of the second pile 2, increasing the contact area between them. Simultaneously, as the bottom of the second pile 2 presses against the top of the first pile 1, the two guide rods 301 are compressed into the interior of the first pile 1. The position of the second pile 2 is then slowly adjusted until the gap between one of the guide rods 301 and the positioning groove 302 is greater than the radius of the top of the guide rod 301. Under compression, the elastic potential energy of the compression spring 303 pushes the guide rod 301 into the positioning groove 302. With the slow swaying of the lifted second pile 2, the guide rod 301 is fully engaged with the positioning groove 302. 2. Insert the guide rod 301 into the positioning groove 302 and rotate the second pile body 2 around the connection point between the guide rod 301 and the positioning groove 302 until the other guide rod 301 is inserted into the positioning groove 302. This enables a quick connection between the first pile body 1 and the second pile body 2 and ensures their coaxial connection. Furthermore, by utilizing the radius difference between the insertion points of the guide rod 301 and the positioning groove 302 in the guide assembly 3, the insertion between one of the guide rods 301 and the positioning groove 302 can be completed in the shortest possible time. This limits the movable axis of the second pile body 2 during connection, reduces the engineering difficulty of connecting the first pile body 1 and the second pile body 2, and improves the efficiency of splicing the first pile body 1 and the second pile body 2.
[0036] After connecting the first pile 1 and the second pile 2, the bolt 401 is tightened into the interior of the first pile 1 and the second pile 2, so that the arc surface at the bottom of the positioning block 4011 contacts the arc surface at the top of the top block 4022. As the bolt 401 and the positioning block 4011 rotate, the positioning block 4011 disengages from the arc surface in contact with the top block 4022 during rotation, and automatically presses down on the top block 4022. This causes the limiting rod 4021 to move downward under the limitation of the limiting groove 402, compressing the strong spring 404 in the annular groove 403. After the bolt 401 rotates one revolution, the arc surface at the bottom of the positioning block 4011 contacts the arc surface at the top of the top block 4022 again, and the strong spring 404 pushes the top block 4022. The top block 4022 and the positioning block 4011 maintain a contact state, and the connection state between the first pile 1 and the second pile 2 is ensured by the continuous rotation of the bolt 401 until the bolt 401 is fully tightened. Then, the arc surface of the top block 4022 abuts against the arc surface of the positioning block 4011 again. Through the cooperation between the top block 4022 and the positioning block 4011 in the fixing assembly 4, while the bolt 401 fixes the first pile 1 and the second pile 2, the strong spring 404 pushes to ensure the contact state between the positioning block 4011 and the top block 4022. This prevents the bolt 401 from loosening under non-human conditions, further improving the stability of the first pile 1 and the second pile 2 after the connection is completed, and improving the practicality of the device in use.
[0037] Please see Figures 1-6 The diagram shows that the top of the second pile body 2 is equipped with a reinforcing component 5, which includes a screw 501. There are four sets of the reinforcing component 5, and the four sets are positioned at a 45-degree angle to the guide rod 301. The screw 501 is threadedly connected to the first pile body 1 and the second pile body 2. A lead screw 502 is threadedly connected inside the screw 501. The bottom of the lead screw 502 is inclined at an angle of 45°±2°. A through groove 5011 is formed inside the screw 501. The through groove 5011 is inverted T-shaped and its bottom penetrates the interior of the screw 501. An insert block 503 is slidably connected to the bottom wall of the through groove 5011, and the insert block 503 is close to the lead screw. One end of 502 is inclined, and the insertion block 503 can be pushed out of the through groove 5011 by the downward movement of the screw 502. The insertion block 503 is inserted into the interior of the first pile body 1. A sliding plate 504 is fixed on the outer wall of the insertion block 503. A sliding groove 5041 for sliding of the sliding plate 504 is opened inside the screw 501. A return spring 505 is elastically connected between the sliding groove 5041 and the sliding plate 504. The return spring 505 has a life of ≥5000 cycles and fatigue strength is verified. By setting the return spring 505, when the screw 502 is not in contact with the insertion block 503, the insertion block 503 can be pulled back into the interior of the through groove 5011.
[0038] When reinforcing the connection between the first pile 1 and the second pile 2, rotate the screw 501 to the interior of the first pile 1 and the second pile 2. Then rotate the lead screw 502 so that the inclined surface at the bottom of the lead screw 502 contacts the inclined surface of the insert block 503. As the lead screw 502 gradually moves downward, it pushes the insert block 503 and the sliding plate 504 to move and stretches the return spring 505 until one end of the insert block 503 is inserted into the interior of the first pile 1. At this point, the lead screw 502 completes its movement synchronously. When it is necessary to disassemble the screw 501, reverse the operation of the lead screw 502. After step 2, under the tension of the return spring 505, the insert block 503 automatically cancels the insertion with the first pile body 1 and retracts into the through groove 5011. Then, through the cooperation of the screw 501 and the lead screw 502 in the reinforcement component 5, the first pile body 1 and the second pile body 2 are reinforced for the second time. At the same time, through the insertion between the insert block 503 and the first pile body 1, the screw 501 is further fixed, which improves the stability of the screw 501 when reinforcing the first pile body 1 and the second pile body 2 and ensures the stability of the connection between the first pile body 1 and the second pile body 2.
