Description

Technical Field

[0001] This utility model relates to the field of pipe pile technology, specifically a pipe pile structure with high structural strength. Background Technology

[0002] Pipe piles are foundation engineering components made of steel pipes and concrete. They are installed in the foundation by driving or vibrating to bear the loads of the building and transfer them to the foundation. Based on manufacturing processes and materials, pipe piles can be divided into several types, such as steel-concrete composite pipe piles, prestressed concrete pipe piles, prestressed concrete thin-walled pipe piles, and high-strength prestressed concrete pipe piles. These different types of pipe piles have different characteristics in terms of bearing capacity, crack resistance, and durability.

[0003] Extensive searches revealed that CN220908386U discloses a prestressed ultra-high strength concrete thick-walled grouting pipe pile, comprising: a pile body, which is cast in cement and has a cylindrical tubular structure, and a reinforcing component is provided on the pile body; characterized in that the reinforcing component is composed of a first reinforcing bar, a groove, and a second reinforcing bar, and the first reinforcing bar is cast in a ring array in the pile body, the first reinforcing bar having a cylindrical rod structure, and the ring array of the first reinforcing bars together constitutes the reinforcing structure of the pile body.

[0004] In existing technologies, when casting pipe piles, the first reinforcing bar is directly cast together with the cement. At this time, the strength of the pile body can be improved by the first reinforcing bar. After the first reinforcing bar is cast into the cement, the overall strength of the pile body can be improved, thereby avoiding the probability of the pile body bending and deformation. Before casting, multiple grooves are made on the first reinforcing bar. After the cement is cast, the cement comes into contact with the first reinforcing bar and multiple grooves. This can improve the adhesion between the cement and the first reinforcing bar and reduce the phenomenon of separation between the cement and the first reinforcing bar.

[0005] However, pipe piles are mostly driven into the ground by a pile driver. If the structural strength of the pipe pile is not up to standard, it will break, especially at the bottom of the pipe pile. Existing pipe pile technology is insufficient in strengthening the bottom structure, specifically in the connection with the steel bars is not tight enough, resulting in uneven stress in some areas. Therefore, a pipe pile structure with high structural strength is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a pipe pile structure with high structural strength, which has the advantages of enhancing the strength of the bottom structure and ensuring that the pipe pile is not easily broken during the piling process. It solves the problems of insufficient reinforcement of the bottom structure of the pipe pile and uneven local stress caused by loose connection with the steel bars in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-strength pipe pile structure, including a pile body, a reinforcement assembly inside the pile body, a top cover at the top of the pile body, and a base at the bottom of the pile body; the base includes a bottom plate, a plug-in column welded and installed in the middle of the bottom of the bottom plate, and a bottom bracket inserted below the bottom plate through the plug-in column; the reinforcement assembly includes longitudinal bars, which are distributed in a circular array, and the bottom of the longitudinal bars passes through the bottom plate and bends at a 90-degree angle.

[0008] Preferably, the pile body adopts a tubular structure design and is integrally formed with the reinforcement components through concrete pouring, and the top outer side of the pile body is shaped with a stepped groove.

[0009] The tubular structure design improves the overall structural strength of the pile while reducing its weight, making it easier to transport and install.

[0010] The use of one-piece molding ensures a tight bond between the concrete and the reinforcement components, improving the stability and durability of the overall structure.

[0011] The stepped groove design provides a convenient interface for the installation of the top cover, while also increasing the load-bearing capacity and stability of the top of the pile.

[0012] Preferably, the top cover is movably mounted on the top of the pile body via a stepped groove, and the top cover has a reserved hole for the top of the longitudinal reinforcement to pass through.

[0013] The top cover is installed using stepped grooves, which simplifies the installation process and improves construction efficiency.

[0014] The design of the pre-drilled holes ensures that the longitudinal reinforcement bars can pass smoothly through the top cover, maintaining the continuity of the reinforcement components and enhancing the overall structural strength of the pile.

[0015] Preferably, the bottom of the base plate has pre-drilled holes arranged in a ring, and pads are inserted into the bottom of the base plate through the pre-drilled holes. The bending point at the bottom of the longitudinal rib does not contact the bottom of the base plate through the pads.

[0016] The design uses spacers to isolate the bent portions of the longitudinal ribs from the bottom of the base plate, avoiding pressure or displacement caused by direct contact and ensuring the stability of the longitudinal ribs and the thickness of the protective layer.

[0017] The design of the pad increases the connection stability between the bottom plate and the longitudinal reinforcement, further enhancing the structural strength of the bottom of the pile.

[0018] Preferably, the base bracket and the base plate are both made of steel plate with a matching material design, the cross-sectional dimensions of the base bracket match the cross-sectional dimensions of the base plate, and the base bracket and the base plate are filled with concrete.

[0019] The design incorporates steel plate cutting techniques to ensure material consistency and structural stability between the base bracket and the base plate.

[0020] The bottom support frame matches the cross-sectional dimensions of the base plate, ensuring the uniformity of the appearance of the pipe piles after the concrete is filled.

[0021] The concrete filling increases the connection strength between the bottom bracket and the bottom plate, improves the overall bearing capacity of the bottom of the pile, and provides protection for the longitudinal reinforcement between the bottom bracket and the bottom plate.

[0022] Preferably, both the longitudinal reinforcement and the stirrups are made of threaded steel, and the stirrups are tied to the outside of the longitudinal reinforcement in a spiral shape with tie wire.

[0023] The choice of rebar material in the design has high strength and toughness, and can withstand large tensile and compressive forces, ensuring the reliability and durability of the reinforcement components.

[0024] The stirrups are spirally tied to the outside of the longitudinal reinforcement, which increases the overall stability and shear resistance of the reinforcement assembly and improves the structural strength of the pile.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] This invention features a base comprising a base plate and a base bracket. The base plate is connected to the base bracket via insert posts and filled with concrete, forming a robust bottom support structure. This design increases the overall load-bearing capacity and stability of the pile bottom. The longitudinal reinforcement bars in the reinforcement assembly are distributed in a circular array, and their bottoms pass through the base plate and bend at a 90-degree angle. This design not only strengthens the internal steel reinforcement skeleton of the pile but also increases the connection strength with the base plate through the bending of the longitudinal reinforcement bars at the bottom, thereby further enhancing the bottom structure.

[0027] Both the longitudinal reinforcement and stirrups are made of threaded steel, a material with high strength and toughness, capable of withstanding significant tensile and compressive forces. Therefore, even under substantial impact when the pipe pile is driven into the ground, it maintains structural integrity and is less prone to breakage. The longitudinal reinforcement extends from the top of the pile to the bottom, bending at a 90-degree angle and forming a tight connection with the base slab. This continuous design ensures that the pipe pile is subjected to uniform stress during driving, avoiding breakage caused by uneven localized stress.

[0028] In summary, this utility model, through its unique design, effectively enhances the structural strength of the bottom of the pipe pile, ensuring that the pipe pile is not easily broken during the piling process, and solves the related problems in the prior art. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model is provided: a high-strength pipe pile structure, including a pile body 2, a reinforcement assembly 3 inside the pile body 2, a top cover 22 at the top of the pile body 2, and a base 1 at the bottom of the pile body 2; the base 1 includes a bottom plate 12, a plug-in column 121 is welded and installed in the middle of the bottom of the bottom of the bottom plate 12, and a bottom bracket 11 is inserted under the bottom of the bottom plate 12 through the plug-in column 121; the reinforcement assembly 3 includes longitudinal bars 31, the longitudinal bars 31 are distributed in a ring array, and the bottom of the longitudinal bars 31 passes through the bottom plate 12 and bends at a ninety-degree angle.

[0037] Specifically, a base 1 is provided, comprising a base plate 12 and a base bracket 11. The base plate 12 is connected to the base bracket 11 via insert posts 121 and filled with concrete, forming a robust bottom support structure. This design increases the overall load-bearing capacity and stability of the pile body 2's bottom. The longitudinal bars 31 in the reinforcement assembly 3 are distributed in a ring array, and their bottoms pass through the base plate 12 and bend at a 90-degree angle. This design not only strengthens the internal steel reinforcement skeleton structure of the pile body 2 but also increases the connection strength with the base plate 12 through the bending of the longitudinal bars 31 at the bottom, thereby further enhancing the bottom structure.

[0038] Both the longitudinal reinforcement 31 and the stirrups 32 are made of threaded steel, a material with high strength and toughness, capable of withstanding significant tensile and compressive forces. Therefore, even under considerable impact when the pipe pile is driven into the ground, it maintains structural integrity and is not easily broken. The longitudinal reinforcement 31 extends from the top to the bottom of the pile body 2, bending at a 90-degree angle and forming a tight connection with the base plate 12. This continuous design ensures that the pipe pile is evenly stressed during driving, avoiding breakage caused by uneven local stress.

[0039] In summary, this utility model, through its unique design, effectively enhances the structural strength of the bottom of the pipe pile, ensuring that the pipe pile is not easily broken during the piling process, and solves the related problems in the prior art.

[0040] Example 2

[0041] To improve the stability of the connection between the reinforcement components and the base and top cover, such as Figure 3 and Figure 4 As shown, in this embodiment, the pile body 2 adopts a tubular structure design and is integrally formed with the reinforcement component 3 by concrete pouring. The top outer side of the pile body 2 is shaped with a stepped groove 21.

[0042] The tubular structure design improves the overall structural strength of pile 2 while reducing weight, making it easier to transport and install.

[0043] The use of one-piece molding ensures a tight bond between the concrete and the reinforcement component 3, improving the stability and durability of the overall structure.

[0044] The stepped groove 21 provides a convenient interface for the installation of the top cover 22, while increasing the load-bearing capacity and stability of the top of the pile 2.

[0045] Furthermore, the top cover 22 is movably attached to the top of the pile body 2 via the stepped groove 21, and the top cover 22 has a reserved hole for the top of the longitudinal reinforcement 31 to pass through.

[0046] In the design, the top cover 22 is installed by a stepped groove 21, which simplifies the installation process and improves construction efficiency.

[0047] The design of the reserved hole ensures that the longitudinal reinforcement 31 can pass smoothly through the top cover 22, maintains the continuity of the reinforcement assembly 3, and enhances the overall structural strength of the pile body 2.

[0048] Furthermore, the bottom of the base plate 12 has pre-drilled holes arranged in a ring array. A pad 13 is inserted into the bottom of the base plate 12 through the pre-drilled holes. The bending point at the bottom of the longitudinal rib 31 does not contact the bottom of the base plate 12 through the pad 13.

[0049] In the design, the bent part of the longitudinal rib 31 is isolated from the bottom of the base plate 12 by the pad block 13, which avoids the pressure or displacement caused by direct contact and ensures the stability of the longitudinal rib 31 and the thickness of the protective layer.

[0050] The design of pad block 13 increases the connection stability between bottom plate 12 and longitudinal reinforcement 31, further enhancing the structural strength of the bottom of pile 2.

[0051] Furthermore, the base bracket 11 and the base plate 12 are both made of steel plate and are designed to match each other. The cross-sectional dimensions of the base bracket 11 and the base plate 12 are matched. The base bracket 11 and the base plate 12 are filled with concrete.

[0052] The design incorporates steel plate cutting to ensure material consistency and structural stability between the base bracket 11 and the base plate 12.

[0053] The cross-sectional dimensions of the bottom bracket 11 and the bottom plate 12 are matched to ensure the consistency of the appearance of the pipe pile after the concrete is filled.

[0054] The concrete filling increases the connection strength between the bottom bracket 11 and the bottom plate 12, improves the overall bearing capacity of the bottom of the pile 2, and provides protection for the longitudinal reinforcement 31 between the bottom bracket 11 and the bottom plate 12.

[0055] Furthermore, both the longitudinal reinforcement 31 and the stirrup 32 are made of threaded steel, and the stirrup 32 is tied to the outside of the longitudinal reinforcement 31 in a spiral shape with tie wire.

[0056] The choice of rebar material in the design has high strength and toughness, and can withstand large tensile and compressive forces, ensuring the reliability and durability of the reinforcement component 3.

[0057] The stirrups 32 are spirally tied to the outside of the longitudinal reinforcement 31, which increases the overall stability and shear resistance of the reinforcement assembly 3 and improves the structural strength of the pile 2.

[0058] When using this invention, prepare the required materials such as concrete of suitable strength, reinforcement components 3, steel plates, and spacers 13. Weld the base plate 12 to the insertion post 121. Place the base bracket 11 in the appropriate position, ready to accept the insertion of the base plate 12 and the insertion post 121. Place the longitudinal reinforcement bars 31 on the base plate 12 according to the design requirements, ensuring they are distributed in a circular array. Pass the bottom of the longitudinal reinforcement bars 31 through the reserved holes in the base plate 12 and bend them at a 90-degree angle. Struts 32 are spirally tied to the outside of the longitudinal reinforcement bars 31 to increase the stability of the structure. Insert spacers 13 into the bottom of the base plate 12 through the reserved holes to ensure that the bent portions of the longitudinal reinforcement bars 31 do not directly contact the base plate 12, thereby avoiding unnecessary pressure or displacement during pouring and ensuring that the longitudinal reinforcement bars 31 have a sufficiently thick protective layer before concrete filling.

[0059] Assemble a mold according to the design dimensions of the pipe pile. This mold will be used to hold the concrete and, after it hardens, form the shape of the pile body 2. Pour concrete into the mold until the desired filling height is reached. During pouring, use appropriate tools such as a vibrator to eliminate air bubbles in the concrete and ensure it tightly wraps around the reinforcement assembly 3. After the concrete is poured and initially set, shape the stepped groove 21 on the top of the pile body 2, and attach the top cover 22 to the top of the pile body 2 through the stepped groove 21, ensuring that the pre-drilled hole on the top cover 22 is aligned with the top of the longitudinal reinforcement 31 so that the longitudinal reinforcement 31 can pass through. Allow the concrete to fully harden in the mold. Once the concrete has fully hardened, the mold can be removed, and the completed pipe pile structure can be taken out.

[0060] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
