Description

Technical Field

[0001] This utility model relates to the field of engineering construction connection technology, specifically a tapered precast concrete pipe pile end plate connector. Background Technology

[0002] Conical-joint precast pipe piles are a type of precast concrete pile that uses conical-joint mechanical joints to connect pile sections, representing an innovative technology in pile foundation engineering. Its core lies in replacing traditional welding with a specially designed mechanical connection device to achieve efficient and reliable connection between pile sections.

[0003] The current conical precast concrete pipe pile end plate connector, as described in patent announcement number CN220364985U, includes a box with a rectangular installation chamber, an upper end plate fixedly installed at the bottom of the upper pipe pile, and a lower end plate fixedly installed at the top of the lower pipe pile. The box is embedded and fixed at the top of the lower pipe pile and welded to the bottom of the lower end plate. A limiting protrusion extending into the rectangular installation chamber is provided at the center of the front inner wall and the center of the rear inner wall of the rectangular installation chamber. A rectangular locking block that slides and installs with the interior of the rectangular installation chamber is provided on the left side of the two limiting protrusions, and a rectangular locking block that slides and installs with the interior of the rectangular installation chamber is also provided on the right side of the two limiting protrusions. A spring in a compressed state is installed between the side of the two rectangular locking blocks that is far away from each other and the inner wall of the corresponding side of the rectangular installation chamber.

[0004] Regarding the aforementioned technologies, the inventors believe that this assembly method achieves tight contact and rapid assembly between the upper and lower end plates by moving the upper end plate downwards, causing the connecting screw to engage in a tapered, plain-textured locking groove. However, this design has significant drawbacks: firstly, the spring extension lacks an effective limiting mechanism; secondly, as the spring ages and deteriorates, it can no longer limit the rectangular locking block. These two problems directly affect the connection stability of the upper and lower end plates, thereby weakening the supporting performance of the pipe pile for the superstructure. Utility Model Content

[0005] The purpose of this utility model is to provide a tapered precast concrete pipe pile end plate connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tapered precast concrete pipe pile end plate connector, including

[0008] A connecting mechanism includes a lower end plate, an upper end plate is provided below the lower end plate, pipe piles are fixedly connected to the opposite sides of the lower end plate and the upper end plate, a hook ring is fixedly connected to the bottom of the lower end plate, multiple hook blocks are snapped into the inside of the hook ring in a ring array, the hook blocks are slidably connected to the upper end plate, and a hexagonal tube is fixedly fixed through the inside of the upper end plate.

[0009] The limiting mechanism includes springs arranged in a ring array and fixedly connected to the outside of the hexagonal tube, with the end of each group of springs away from the hexagonal tube being fixedly connected to the hook block.

[0010] As a further embodiment of this utility model: a sealing ring is fixedly connected to the bottom of the hook ring, and the sealing ring abuts against the upper end plate.

[0011] As a further embodiment of this utility model: an extension ring is fixedly connected to the top of the upper end plate, and the extension ring is sleeved on the outside of the hook ring.

[0012] As a further embodiment of this utility model: each group of hook blocks has a T-shaped groove at its bottom, and each group of T-shaped grooves has a T-shaped guide rail that is slidably connected to the hook block inside, and each group of T-shaped guide rails is fixedly connected to the upper end plate.

[0013] As a further embodiment of this utility model: each group of hook blocks has a sliding rod that slides through its interior, each group of sliding rods is fixedly connected to the hexagonal tube, each group of hook blocks has a limiting groove on its opposite side, each group of limiting grooves has a limiting block inside its interior, and each group of limiting blocks is fixedly connected to each group of sliding rods.

[0014] As a further embodiment of this utility model: multiple reinforcing ribs are fixedly connected to the outer side of the hexagonal tube in a ring array, and each group of reinforcing ribs is fixedly connected to the upper end plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] With the above-described structure, this utility model, through the cooperation of the hook ring, hook block, hexagonal tube, and spring, allows each set of hook blocks to move inwards when the hook ring moves to the top of the upper end plate. Each set of hook blocks is then pushed into engagement with the hook ring by the elastic action of its respective spring, thus limiting the hook ring's position. This allows concrete to flow through the hexagonal tube into the lower pipe pile during subsequent pouring, while the hook block and spring are submerged in the concrete. After the concrete solidifies, the hook block and spring can be fixed, thereby improving the connection stability between the lower and upper end plates, and consequently enhancing the stability of the pipe pile's support for the upper structure.

Detailed Implementation

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Please see Figure 1-4 A conical precast concrete pipe pile end plate connector includes a connecting mechanism 1. The connecting mechanism 1 includes a lower end plate 101 and an upper end plate 102 below the lower end plate 101. Pipe piles 103 are fixedly connected to the opposite sides of the lower end plate 101 and the upper end plate 102. A hook ring 107 is fixedly connected to the bottom of the lower end plate 101, and an extension ring 104 is fixedly connected to the top of the upper end plate 102. The extension ring 104 is sleeved on the outside of the hook ring 107. The extension ring 104 is provided to fit into the outside of the hook ring 107, thereby limiting the hook ring 107 and reducing the probability of the hook ring 107 expanding outward and deforming.

[0025] The hook ring 107 has multiple hook blocks 108 arranged in a ring array inside. The hook blocks 108 are designed to limit the movement of the hook ring 107 after it is engaged and fixed, thereby achieving the connection and fixation between the lower end plate 101 and the upper end plate 102. The hook blocks 108 are slidably connected to the upper end plate 102. A sealing ring 109 is fixedly connected to the bottom of the hook ring 107. The sealing ring 109 abuts against the upper end plate 102 and is used to seal the gap between the hook ring 107 and the upper end plate 102.

[0026] Each set of hook blocks 108 has a T-shaped groove 207 at its bottom. Each T-shaped groove 207 contains a T-shaped guide rail 206 that slides through the hook block 108. Each T-shaped guide rail 206 is fixedly connected to the upper end plate 102. The T-shaped guide rail 206 guides the sliding of the hook block 108. Each set of hook blocks 108 has a sliding rod 202 that slides through it. Each sliding rod 202 is fixedly connected to the hexagonal tube 106. Each set of hook blocks 108 has a limiting groove 204 on its opposite side. Each limiting groove 204 contains a limiting block 203, which is fixedly connected to the sliding rod 202. The limiting block 203 limits the sliding of the hook block 108, reducing the probability of the hook block 108 disengaging from the outside of the T-shaped guide rail 206.

[0027] A hexagonal tube 106 is fixedly installed through the interior of the upper end plate 102, allowing concrete to pass through. Multiple reinforcing ribs 205 are fixedly connected in a circular array to the outer side of the hexagonal tube 106. Each set of reinforcing ribs 205 is fixedly connected to the upper end plate 102, further connecting and fixing the upper end plate 102 and the hexagonal tube 106, thereby improving the connection stability between the hexagonal tube 106 and the upper end plate 102. A limiting mechanism 2 includes springs 201 fixedly connected in a circular array to the outer side of the hexagonal tube 106. The end of each spring 201 away from the hexagonal tube 106 is fixedly connected to a hook block 108. The springs 201 use their elasticity to push the hook block 108 towards the hook ring 107, reducing the probability of the hook block 108 detaching from the hook ring 107.

[0028] When it is necessary to connect the lower end plate 101 and the upper end plate 102, the hook ring 107 can be inserted into the extension ring 104, so that each set of hook blocks 108 is pushed by the elastic action of each set of springs 201 and engages with the hook ring 107, thereby limiting the hook ring 107 and fixing the connection between the lower end plate 101 and the upper end plate 102. After the pipe pile construction is completed, concrete can be poured into the topmost pipe pile until the concrete fills all layers of pipe piles. When pouring concrete, the concrete will flow into the interior of the upper end plate 102, the extension ring 104 and the lower end plate 101, so that all internal parts are submerged in concrete. After the concrete solidifies, the springs 201 and hook blocks 108 are fixed by the concrete, making the connection between the lower end plate 101 and the upper end plate 102 more stable, thereby improving the support stability of the pipe pile for the superstructure.

[0029] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
