Description

Technical Field

[0001] The utility model relates to the technical field of precast concrete, in particular to a precast concrete pipe. Background Art

[0002] At present, pipe piles are used more and more widely in the construction process. The pile foundations used in my country's construction industry are roughly divided into precast piles and cast-in-place piles. Precast piles are divided into concrete piles and steel piles. Precast concrete pipe piles are also basic components in construction projects, with the advantages of high single pile bearing capacity, fast construction speed, short construction period and low cost.

The upper connecting part includes a plurality of upper end plates arranged along the end of the upper pipe pile, an upper fixed plate arranged along the end of the upper pipe pile, and the upper end plate extends out of the end face of the upper pipe pile. The lower connecting part includes a plurality of lower end plates arranged along the end of the lower pipe pile, and a lower fixed plate arranged along the end of the lower pipe pile. The lower end plate extends out of the end face of the lower pipe pile. Both the upper fixed plate and the lower fixed plate are provided with connecting holes, and a fixing assembly is provided in the connecting hole. The fixing assembly is used to connect and fix the upper fixed plate and the lower fixed plate. The present application has the effect of facilitating the connection of pipe piles and improving construction efficiency.

[0004] However, when the above device is in use, multiple sets of connecting components are needed to position and install the upper and lower pipe piles, which requires high processing accuracy. Once a set of connecting components deviates, the upper and lower pipe piles cannot be installed, which has certain performance deficiencies. Utility Model Content

A connecting assembly 9 is arranged between the upper and lower pipe pile bodies 2 and 1; the connecting assembly 9 comprises a mounting plate 901, a clamping plate 902 is rotatably connected to the surface of the mounting plate 901, a clamping block 903 is fixedly connected to one side of the clamping plate 902, a limiting block 904 is symmetrically arranged on the surface of the mounting plate 901, a sliding block 905 is slidably connected between the limiting blocks 904, a threaded rod 906 that penetrates the sliding block 905 is rotatably connected to the mounting plate 901, a rotating block 907 is fixedly connected to one end of the threaded rod 906, and the threaded rod 906 is threadedly connected to the sliding block 905. The upper pipe pile body 2 has the same size as the lower pipe pile body 1, and one end of the upper pipe pile body 2 and the lower pipe pile body 1 are both provided with chamfers.

[0027] Analysis of the above content: First, the lower pipe pile body 1 is driven vertically into the ground, and a part of the lower pipe pile body 1 is left to connect with the upper pipe pile body 2. A chamfer is set to facilitate driving the lower pipe pile body 1 into the ground. The upper pipe pile body 2 is lifted, so that the end face of the upper pipe pile body 2 is aligned with the end face of the lower pipe pile body 1, and the upper pipe pile body 2 is slowly lowered. The upper pipe pile body 2 is adjusted so that the positioning column 6 can extend into the positioning hole 5. Under the mutual cooperation of the positioning hole 5 and the positioning column 6, the lower pipe pile body 1 and the upper pipe pile body 2 will not rotate, and can be better fixed. When the upper pipe pile body 2 is lowered, the clamping block 903 is clamped on the upper limit groove 7 and the lower limit groove 8, and the rotating block 907 is rotated. Under the action of the rotating block 907, the threaded rod 906 is driven to rotate, so that the sliding block 905 moves toward the mounting plate 901, and the clamping plate 902 is opened, so that the clamping block 903 is subjected to force, and the upper connecting ring 3 and the lower connecting ring 4 are clamped, so as to fix the lower pipe pile body 1 and the upper pipe pile body 2.

[0028] Embodiment 2:

[0029] See also Figure 1-4 The utility model provides a technical solution based on the first embodiment: the upper limit groove 7 is the same size as the lower limit groove 8, the height of the clamping block 903 is the same as the depth of the upper limit groove 7, and arc surfaces matching the upper limit groove 7 are arranged on both sides of the clamping block 903.

[0030] Analysis of the above content: The upper limit groove 7 and the lower limit groove 8 cooperate with each other to limit the position of the clamping block 903 to prevent the clamping block 903 from moving. The clamping block 903 is stuck in the upper limit groove 7 and the lower limit groove 8, which can better clamp the upper connecting ring 3 and the lower connecting ring 4.

[0031] Embodiment three:

[0032] See also Figure 1-4 The utility model provides a technical solution based on the first embodiment: a sealing assembly 11 is provided on the lower pipe pile body 1, and the sealing assembly 11 includes a lower sealing groove 1101 opened on the upper surface of the lower pipe pile body 1, and an upper raised strip 1102 is inserted in the lower sealing groove 1101, and an upper sealing groove 1104 is opened at the bottom of the upper connecting ring 3, and a lower raised strip 1103 is inserted on the upper sealing groove 1104.

[0033] Analysis of the above content: the upper raised strip 1102 extends into the lower sealing groove 1101, and the lower raised strip 1103 extends into the upper sealing groove 1104. The lower sealing groove 1101, the upper raised strip 1102, the lower raised strip 1103 and the upper sealing groove 1104 cooperate with each other to ensure the sealing when the lower pipe pile body 1 is connected to the upper pipe pile body 2.

[0034] Embodiment 4:

[0035] See also Figure 1-4 The utility model provides a technical solution based on the first embodiment: the lower raised strip 1103 is fixedly connected to the upper surface of the lower connecting ring 4, and the upper raised strip 1102 is fixedly connected to the lower surface of the upper pipe pile body 2.

[0036] Analysis of the above content: The staggered arrangement of the lower raised strips 1103 and the upper raised strips 1102 can achieve a better sealing effect.

[0037] Embodiment five:

[0038] See also Figure 1-4 The utility model provides a technical solution based on the first embodiment: the upper pipe pile body 2 and the bottom surface of the upper connecting ring 3 are in the same horizontal plane, and the lower pipe pile body 1 and the top surface of the lower connecting ring 4 are in the same horizontal plane.

[0039] Analysis of the above content: By fixing the upper connecting ring 3 and the lower connecting ring 4, the lower pipe pile body 1 and the upper pipe pile body 2 are fixed. The lower pipe pile body 1 and the upper pipe pile body 2 are connected by pure physical structure, and there is no need to weld the lower pipe pile body 1 and the upper pipe pile body 2, thereby shortening the construction period and improving the construction efficiency.

[0040] Embodiment six:

[0041] See also Figure 1-4 The utility model provides a technical solution based on the first embodiment: the width of the sliding block 905 is the same as the spacing between the two sets of limit blocks 904, and the clamping plate 902 is symmetrically arranged on the mounting plate 901.

[0042] Analysis of the above content: The limit block 904 is used to limit the sliding block 905, ensuring that the sliding block 905 can move toward the mounting plate 901 when the threaded rod 906 rotates. The movement of the sliding block 905 opens the clamping plate 902, so that the clamping block 903 clamps the upper connecting ring 3 and the lower connecting ring 4.
