Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a connection structure between a precast pile and a pile cap. Background Technology

[0002] A pile cap is a reinforced concrete platform built on top of the piles to support and distribute the loads transmitted from the pier body, connecting the tops of each pile.

[0003] In related technologies, the construction of a foundation requires the support of the foundation by precast piles. Reinforcing bars are pre-embedded in the precast piles, and then the foundation is cast to form a connection between the precast piles and the foundation. However, due to different designs, different foundations require different lengths of reinforcing bars, making it impossible to manufacture precast piles with uniform specifications, which affects the progress of the project. Utility Model Content

[0004] The purpose of this application is to provide a connection structure between precast piles and pile caps.

[0005] To facilitate the connection of precast piles with different pile caps, this application adopts the following technical solution: A connection structure between a precast pile and a pile cap includes a precast pile body, a groove is provided on the top of the precast pile body, a plurality of steel bar holes are provided in the groove, a plurality of pre-embedded steel bars are pre-embedded in the steel bar holes, one end of the pre-embedded steel bar passes through the bottom of the groove and is connected to an anchoring steel bar, a sleeve is provided at the connection between the anchoring steel bar and the pre-embedded steel bar, one end of the precast pile body is connected to a pile cap, and the anchoring steel bar passes through the pile cap.

[0006] By adopting the above technical solution, the pre-embedded steel bars are placed in the precast pile body and connected to the sleeve. Different anchoring steel bars can be used to connect with the pre-embedded steel bars, thereby achieving uniformity of the pre-embedded steel bar body specifications. The anchoring steel bars use a length that matches the pile cap, which facilitates the production of the precast pile body and improves construction efficiency.

[0007] Preferably, a stabilizing ring is connected to the side of the sleeve near the bottom of the groove, and one side of the stabilizing ring is used to abut against the bottom of the groove.

[0008] By adopting the above technical solution, the stabilizing ring can further improve the stability of the sleeve.

[0009] Preferably, the embedded steel bar and the sleeve are connected by welding.

[0010] By adopting the above technical solutions, welding can improve construction efficiency while achieving a stable effect.

[0011] Preferably, the sleeve is provided with threads, and the end of the anchoring steel bar near the pre-embedded steel bar is provided with threads, and the sleeve and the anchoring steel bar are connected by threads.

[0012] By adopting the above technical solution, threaded connection can further facilitate the connection between sleeve and anchoring steel bar, and improve installation efficiency.

[0013] Preferably, a support rod is provided between the sleeve and the stabilizing ring.

[0014] By adopting the above technical solution, the support rod can improve the stability of the sleeve and reduce the possibility of sleeve tilting.

[0015] Preferably, a fixing rod is connected between adjacent anchoring bars, and the fixing rod and the anchoring bars are welded together.

[0016] By adopting the above technical solution, connecting the fixing rods between adjacent anchoring bars can improve the stability of the structure between multiple anchoring bars and reduce the possibility of the anchoring bars tilting.

[0017] Preferably, multiple pre-embedded steel bars are arranged rotationally symmetrically about the center of the precast pile body.

[0018] By adopting the above technical solution, the pre-embedded steel bars with central rotational symmetry can make the stress on the precast pile body more balanced and improve the stability of the precast pile body.

[0019] The beneficial effects of the chip test station base proposed in this application are as follows: By placing the pre-embedded steel bars inside the precast pile body and connecting them to the sleeve, different anchoring steel bars can be used to connect with the pre-embedded steel bars, thereby achieving uniformity in the specifications of the pre-embedded steel bar body. The anchoring steel bars use a length that matches the pile cap, which facilitates the fabrication of the precast pile body and improves construction efficiency. Attached Figure Description

[0024] The present application will now be described in further detail with reference to Embodiment 1. It should be understood that the specific embodiments described herein are merely illustrative of the present application and not intended to limit its scope. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0025] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] The following reference Figure 1-3 This application provides a connection structure between a precast pile and a pile cap.

[0027] Reference Figure 1 and 2 A connection structure between a precast pile and a pile cap includes a precast pile body 1 and a pile cap 2 connected to the precast pile body 1.

[0028] Reference Figure 1 and 2 The top of the precast pile body 1 is provided with a groove 3, and multiple steel bar holes 4 are provided in the groove 3. Multiple pre-embedded steel bars 5 are pre-embedded in the steel bar holes 4. In this embodiment, four pre-embedded steel bars 5 are provided, and the four pre-embedded steel bars 5 are arranged symmetrically about the center of the precast pile body 1.

[0029] Reference Figure 2 and 3 The pre-embedded steel bar 5 is fixedly connected to a sleeve 7 at one end near the bearing platform 2. The sleeve 7 and the pre-embedded steel bar 5 are connected by welding, and part of the pre-embedded steel bar 5 is inserted inside the sleeve 7.

[0030] Reference Figure 2 and 3 The sleeve 7 is threaded, and the pre-embedded steel bar 5 is connected to the anchoring steel bar 6 at one end near the sleeve 7. One end of the anchoring steel bar 6 passes through the sleeve 7 and is threaded on the end side wall. The anchoring steel bar 6 is threadedly connected to the sleeve 7 and passes through the foundation 2.

[0031] Reference Figure 2 and 3 To improve the stability of the sleeve 7, a stabilizing ring 8 is fixedly connected to the side of the sleeve 7 near the bottom of the groove 3, and one side of the stabilizing ring 8 abuts against the bottom of the groove 3.

[0032] Reference Figure 2 and3 A support rod 9 is fixedly connected between the side wall of the sleeve 7 and the stabilizing ring 8. In this embodiment, two support rods 9 are symmetrically arranged about the center of the sleeve 7. The support rods 9 improve the stability of the sleeve 7 structure and reduce the possibility of the sleeve 7 tilting.

[0033] Reference Figure 1 and 3 In order to improve the stability between the anchoring steel bars 6, a fixing rod 10 is fixedly connected between adjacent anchoring steel bars 6. Both ends of the fixing rod 10 are welded to the anchoring steel bars 6. The fixing rod 10 can improve the stability of the structure between multiple anchoring steel bars 6 and reduce the possibility of the anchoring steel bars 6 tilting.
