Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a prefabricated pipe pile connection auxiliary device. Background Art

[0002] During the static pressure pile construction process, after the first section of prefabricated pipe piles is pressed to the specified elevation by the static pressure machine, the hydraulic crane begins to lift the second section of the pile for pile pressing to meet the construction requirements.

[0003] After searching, a Chinese patent with announcement number CN221072595U discloses an auxiliary pile connector, including a casing and a reinforcement rib. The number of the casings is two, and the two casings are connected by a reinforcement rib. A first hydraulic rod is fixedly installed on both sides of the inner wall of the casing, and a plurality of second hydraulic rods are fixedly installed on both sides of the first hydraulic rod. A support plate is provided on one side of the first hydraulic rod and the second hydraulic rod.

[0004] Based on the above search combined with the existing technology, we found that;

[0005] Although the above patent can stably clamp the upper and lower pile sections, they are only connected by a pair of reinforcing ribs, and the stability of the connection is poor. In addition, when the upper pile section is pushing the lower pile section to the welding elevation, the lower pile section is affected by various factors such as soil geological conditions, and the verticality often has a certain degree of deviation. During welding, it is easy for the misalignment deviation between the upper and lower sections to be large, which cannot meet the acceptance requirements. Therefore, there are certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a prefabricated pipe pile connection auxiliary device, which can be used to firmly fix the upper and lower sections of the pile to prevent large misalignment deviations and facilitate welding processing.

[0007] The technical solution to achieve the purpose of the utility model is: a prefabricated pipe pile connection auxiliary device, including an arc-shaped steel plate, the top and bottom of the arc-shaped steel plate are fixedly installed with an arc-shaped clamp 1, each arc-shaped clamp 2 is provided on one side of the arc-shaped clamp 1, and a pair of fixing bolts are threadedly connected between the arc-shaped clamp 1 and the arc-shaped clamp 2.

[0008] In some embodiments, a rubber gasket is fixedly mounted on the inner curved surface of each of the arc-shaped clamp 1 and the arc-shaped clamp 2.

[0009] In some embodiments, an upper section pile is fixedly clamped between the arc clamp 1 and the arc clamp 2 located at the top of the arc steel plate, and a lower section pile is fixedly clamped between the arc clamp 1 and the arc clamp 2 located at the bottom of the arc steel plate.

[0010] In some embodiments, a pair of U-shaped reinforcing ribs are fixedly installed on the sides of a pair of arc-shaped clamps 1 and arc-shaped clamps 2 respectively.

[0011] In some embodiments, a plurality of fixing blocks are fixedly mounted on the surface of each of the arc-shaped clamp 1 and the arc-shaped clamp 2 away from the arc-shaped steel plate, and an arc-shaped fixing plate is commonly fixedly mounted on the end of each of the fixing blocks.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] First: the utility model can stably connect the upper and lower pile sections by using the arc clamp one and the arc clamp two, and can make the connection between the arc clamp one and the arc clamp two more firmly by using the fastening bolts, and can ensure that the upper and lower pile sections will not have misalignment deviations by using the arc steel plate. In addition, by using the fixing block and the arc fixing plate, the contact area between the device and the upper and lower pile sections can be increased to make the pile connection more stable, thereby ensuring the verticality requirements of the prefabricated pipe piles. The structural strength of the device is improved by using the U-shaped reinforcement ribs, and the design of the "U"-shaped structure ensures that the U-shaped reinforcement ribs are at a certain distance from the surfaces of the upper and lower piles, thereby ensuring that the subsequent welding process will not be hindered, thereby improving the practicability of the device, facilitating operation, and effectively improving the welding quality of the prefabricated pipe pile connections.

[0014] Secondly, the utility model provides corresponding rubber gaskets inside the arc clamp 1 and the arc clamp 2, so that the device can play a certain buffering and protective role when the upper and lower pile sections are stably connected, preventing damage to the surfaces of the upper and lower pile sections when the piles are connected, affecting the use, and improving the integrity of the prefabricated pipe piles.

[0015] The above-mentioned patent solves the problem that although the upper and lower pile sections can be stably clamped, they are only connected by a pair of reinforcing ribs, and the stability of the connection is poor. In addition, when the upper pile section is pushing the lower pile section to the welding elevation, the lower pile section is affected by various factors such as soil geological conditions, and the verticality often has a certain degree of deviation. During welding, the misalignment deviation between the upper and lower sections is prone to be large, and the acceptance requirements cannot be met. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model provides a prefabricated pipe pile connection auxiliary device through improvement. The technical solution of the utility model is:

[0025] Embodiment 1

[0026] like Figure 1-2 As shown, a prefabricated pipe pile connection auxiliary device includes an arc-shaped steel plate 1, and an arc-shaped clamp 2 is fixedly installed on the top and bottom of the arc-shaped steel plate 1. An arc-shaped clamp 2 3 is arranged on one side of each arc-shaped clamp 2. A pair of fixing bolts 4 are threadedly connected between the arc-shaped clamp 2 and the arc-shaped clamp 2 3. The arc-shaped clamp 2 and the arc-shaped clamp 2 3 can be stably fixed and installed by the fixing bolts 4, thereby ensuring smooth pile connection.

[0027] like Figure 1-2 As shown, the inner arc surface of each arc clamp 1 2 and arc clamp 2 3 is fixedly installed with a rubber gasket 7. The rubber gasket 7 can be set to fix the upper section pile 5 and the lower section pile 6 to protect them well, prevent damage to the prefabricated pipe piles and affect their use.

[0028] like Figure 1-2 As shown, an upper section pile 5 is fixedly clamped between the arc clamp 1 2 and the arc clamp 2 3 located at the top of the arc steel plate 1, and a lower section pile 6 is fixedly clamped between the arc clamp 1 2 and the arc clamp 2 3 located at the bottom of the arc steel plate 1. The arc clamp 1 2 and the arc clamp 2 3 can be used to stably connect and fix the upper section pile 5 and the lower section pile 6, which is convenient for welding processing. At the same time, the clamping and fixing method facilitates the installation and disassembly of the device.

[0032] like Figure 3-4 As shown, a pair of U-shaped reinforcing ribs 8 are fixedly installed on the sides of a pair of arc-shaped clamps 1 2 and arc-shaped clamps 2 3 respectively. By setting the U-shaped reinforcing ribs 8, not only the structural strength of the device can be increased, but also the device can be made more stable and reliable during the pile connection process. At the same time, the design of the U-shaped structure ensures that the U-shaped reinforcing ribs 8 are at a certain distance from the welding point, which will not affect the welding process.
