Description

Technical Field

[0001] The utility model relates to the technical field of pipe pile core filling, and particularly relates to a precast pipe pile embedded part for supporting and cushioning the bottom plate of a core filling steel reinforcement cage. Background Art

[0002] Industrial buildings, public buildings and civil building foundations select different pile foundations according to different geological conditions. It is more reasonable to use precast pipe pile foundations under special geological conditions. According to relevant specifications, after the precast pipe piles are inserted or jacked statically, reinforced concrete pouring and core filling need to be carried out according to the specifications.

[0003] In the current pouring and core filling process, the welding quality of the steel plates at the bottom of the steel reinforcement cage is often uneven, which may lead to the falling off of the welded bottom steel plate during the concrete core filling process, resulting in serious over-square of the concrete.

[0004] There is a certain gap between the circular steel plate at the bottom of the core filling steel reinforcement cage and the pipe pile. During the concrete core filling process, slurry leakage occurs, resulting in quality problems such as non-compactness and holes in the bottom concrete. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a precast pipe pile embedded part for supporting and cushioning the bottom plate of a core filling steel reinforcement cage, which can avoid slurry leakage during the pouring of the core filling steel reinforcement cage and ensure that the bottom steel plate of the steel reinforcement cage does not fall off during grouting.

[0006] To solve the above technical problems, the utility model adopts the following technical scheme: a precast pipe pile embedded part for supporting and cushioning the bottom plate of a core filling steel reinforcement cage, including a support ring and a plurality of support components. The support component includes a buckle that can be clamped on the vertical bars and horizontal bars of the pipe pile steel reinforcement cage, and a support plate connected to the buckle and perpendicular to the vertical bars. The support ring can be connected to a plurality of the support plates, and the support ring and the corresponding connection parts of the support plates with the support ring are located in the hollow part of the pipe pile, and the outer side of the support ring abuts against the inner wall of the pipe pile.

[0007] Further, the support component further includes a clamp connected to the support plate by a connecting rod, and the clamp can be clamped with the vertical bar.

[0008] Further, the buckle includes a first U-shaped block that can be clamped on both sides of the vertical bar and two second U-shaped blocks that can be respectively clamped on the corresponding parts of the horizontal bar on both sides of the vertical bar.

[0009] Further, the two second U-shaped blocks are clamped on the horizontal bar from top to bottom.

[0010] Further, the first U-shaped block is connected to the second U-shaped block, and the first U-shaped block and the second U-shaped block form an "﹁" shaped structure.

[0011] Furthermore, the support ring is provided with a plurality of clamping parts that are clamped with the plurality of support plates in a one-to-one correspondence.

[0012] Furthermore, the clamping member includes a spring piece spaced apart from the support ring, and the cross section of the spring piece is in a "﹀" shape.

[0013] Furthermore, the support ring is provided with a plurality of guide bars, and the support plate is provided with guide grooves that are slidably engaged with the guide bars.

[0014] The beneficial effects of the present invention are as follows:

[0015] The prefabricated pipe pile embedded parts of the utility model support the steel plate at the bottom of the core-filling steel cage by arranging multiple support components on the pipe pile steel cage to support the support ring. After the pipe pile steel cage is poured with concrete to form the pipe pile, the support ring and the support plate corresponding to the connection part with the support ring are located in the hollow of the pipe pile. When the core-filling steel cage is lowered, the bottom circular steel plate of the core-filling steel cage is erected on the support ring, which avoids the circular steel plate from falling off. Since the outer side of the support ring is against the inner wall of the pipe pile, the gap problem between the circular steel plate and the pipe pile is solved, and leakage of concrete when filling the core is avoided.

[0026] The prefabricated pipe pile embedded part of the utility model for supporting the steel plate at the bottom of the core-filled steel cage is provided with multiple support assemblies 2 on the pipe pile steel cage 3 to support the support ring 1. After the concrete of the pipe pile steel cage 3 is poured to form the pipe pile 2, the support ring 1 and the support plate 202 corresponding to the connection part with the support ring 1 are located in the hollow of the pipe pile 4. When the core-filled steel cage is lowered, the bottom circular steel plate of the core-filled steel cage is set on the support ring 1, which prevents the circular steel plate from falling off. In addition, because the outer side of the support ring 1 is against the inner wall of the pipe pile 4, the gap problem between the circular steel plate and the pipe pile is solved, and the leakage of concrete during core filling is avoided.

[0027] In this embodiment, the support ring 1 can also be directly connected to the pipe pile 4 through concrete when the pipe pile reinforcement cage 3 is cast, that is, when the pipe pile 4 is formed;

With such a design, by performing three-point clamping with the pipe pile steel cage 3, the stability of the connection between the support plate 202 and the pipe pile steel cage 3 is ensured.

[0031] In this embodiment, referring to Figure 5 , the two second U-shaped blocks 2012 are clamped on the horizontal rib 302 from top to bottom. With such a design, in cooperation with the first U-shaped block 2011, it can prevent the buckle 201 from rotating after being clamped with the pipe pile steel cage 3, ensuring the vertical state of the support plate 202 and the vertical rib 301.

[0032] In this embodiment, referring to Figure 5 , the first U-shaped block 2011 is connected to the second U-shaped block 2012, and the first U-shaped block 2011 and the second U-shaped block 2012 form a "﹁" shaped structure. With such a design, after the buckle 201 is inserted into the vertical rib 301 and then moved down, it can be inserted into the horizontal rib 302, which is convenient for operation. And with the end of the first U-shaped block 2011 as the support of the second U-shaped block 2012, the clamping stability of the second U-shaped block 2012 is ensured.

[0033] In this embodiment, referring to Figure 4 , a plurality of clamping members 5 corresponding to the plurality of support plates 202 one by one are further provided on the support ring 1. With such a design, the connection between the support ring 1 and the support plate 202 is made stable, avoiding the displacement of the support ring 1 when the pipe pile steel cage 3 is lowered.

[0034] In this embodiment, referring to Figure 6 , the clamping member 5 includes a spring piece 501 spaced from the support ring 1, and the cross-section of the spring piece 501 is in a "﹀" shape. With such a design, the inserted support plate 202 can be clamped and fixed through the corner of the spring piece 501.

[0035] In this embodiment, refer to Figure 3 and 4 . A plurality of guiding bars 101 are further provided on the supporting ring 1, and guiding grooves 2021 which are in sliding fit with the guiding bars 101 are further formed on the supporting plate 202. With such a design, the sliding fit between the guiding bars 101 and the guiding grooves 2021 realizes the guiding for the clamping of the clamping member 5 and the supporting plate 202.
