Description

Technical Field

[0001] This utility model belongs to the field of precast pipe pile construction technology, specifically relating to a precast pipe pile fixing steel support structure. Background Technology

[0002] The photovoltaic (PV) support foundation is the cornerstone of the entire PV system, and its stability and durability directly affect the power generation efficiency and safety of the system. PV support foundations come in many types, including cast-in-place concrete pile foundations, high-strength precast pipe piles, and spiral steel piles. Currently, the most commonly used is the PHC high-strength precast pipe pile. By prefabricating the pipe piles, and selecting appropriate construction techniques based on geological conditions, they can be directly driven into softer soil layers, while those in harder soil layers require pre-drilling and pile installation. Typically, PHC precast pipe piles require pre-drilling. For hard strata with extremely low soil content, such as gravel or crushed stone layers, drilling is difficult and prone to collapse. This results in the pre-drilled hole diameter being much larger than the diameter of the PHC high-strength precast pipe pile. During pile installation, it is difficult to align the pile center point, and the pile spacing, verticality, and elevation are difficult to adjust and control. This leads to uneven pile top elevations and unevenness in the pile foundation, resulting in compromised construction quality, hindering subsequent concrete pouring, and affecting the installation quality of photovoltaic brackets and modules. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a precast pipe pile fixing steel support structure. By symmetrically setting semi-circular left and right clamps to fit and fix the pipe pile position, and through the support feet on the support frame, a stable and reliable support system is formed. This solves the problems encountered during pile planting, such as difficulty in aligning the pile center point, difficulty in adjusting and controlling pile spacing, pipe pile verticality, and elevation, which can lead to uneven pile top elevations and tilting, compromised construction quality, and hinder subsequent concrete pouring and the installation quality of photovoltaic supports and components.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a precast pipe pile fixing steel support structure, including a clamp for supporting the bottom of the outer wall of the pipe pile, a support frame is provided on the outer periphery of the clamp, the clamp includes a left clamp and a right clamp symmetrically arranged on the left and right sides, and bent wing plates are provided at both ends of the arc of the left clamp and the right clamp. Several bolt holes are opened on the wing plates. The left clamp and the right clamp are fixed to the outer wall of the pipe pile by bolts. The outer walls of the left clamp and the right clamp are fixedly connected to the support frame by welding. The outer end of the support frame away from the clamp is provided with a support foot for placing on the ground. Two support frames are welded on the left clamp and the right clamp respectively. The four support frames are welded to the outer wall of the clamp in a cross shape.

[0005] Preferably, the support frame includes a fixed rod perpendicular to the bottom of the outer wall of the clamp, and a support rod is inclinedly arranged on the fixed rod, with the outer end of the support rod connected to the outer wall of the clamp.

[0006] Preferably, the fixing rod, the support rod, and the clamp form a triangular support.

[0007] Preferably, a connecting ring is provided at the outer end of the fixing rod away from the clamp, and the support foot passes through the connecting ring and is placed on the ground.

[0008] Preferably, the support foot includes a fixed plate placed on the ground, a fixed cylinder is provided perpendicular to the center of the fixed plate, and a connecting rod is inserted into the fixed cylinder.

[0009] Preferably, the connecting ring is a cylinder, and the connecting rod is a rod with a smooth surface.

[0010] Preferably, the connecting ring is a hexagonal nut and the connecting rod is a threaded rod.

[0011] Preferably, a crossbar is provided at the top of the connecting rod.

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0021] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a precast pipe pile fixing steel support structure includes a clamp 2 for supporting the bottom of the outer wall of the pipe pile 1. A support frame 3 is provided on the outer periphery of the clamp 2. The clamp 2 includes a left clamp 21 and a right clamp 22 symmetrically arranged on the left and right sides. The two ends of the arc of the left clamp 21 and the right clamp 22 are provided with bent wing plates 23. Several bolt holes 24 are opened on the wing plates 23. The left clamp 21 and the right clamp 22 are fixed to the outer wall of the pipe pile 1 by bolts 4. The outer walls of the left clamp 21 and the right clamp 22 are fixedly connected to the support frame 3 by welding. The outer end of the support frame 3 away from the clamp 2 is provided with a support foot 5 for placing on the ground. Two support frames 3 are welded on the left clamp 21 and the right clamp 22 respectively. The four support frames 3 are welded to the outer wall of the clamp 2 in a cross shape.

[0022] This utility model proposes a fixed steel support structure for precast pipe piles 1, designed to stably support the precast pipe piles 1 and ensure their stability and safety during construction and subsequent use. The clamp 2 is attached to the bottom of the outer wall of the precast pipe pile 1, providing necessary radial support. The clamp 2 adopts a split design, consisting of two symmetrically arranged semi-circular parts, namely the left clamp 21 and the right clamp 22. This not only facilitates installation and disassembly but also accommodates pipe piles 1 of different diameters, improving the versatility and flexibility of the structure.

[0023] Both ends of the arc of the left clamp 21 and the right clamp 22 are provided with bent wing plates 23, which not only increase the contact area between the clamp 2 and the pipe pile 1, but also achieve a reliable connection between the various parts of the clamp 2 through several bolt holes 24. The left clamp 21 and the right clamp 22 are fastened to each other by bolts 4 passing through the corresponding bolt holes 24, thereby ensuring that the clamp 2 is firmly fixed to the outer wall of the pipe pile 1 and effectively preventing lateral displacement of the pipe pile 1.

[0024] Four support frames 3 are evenly arranged around the outer periphery of the clamp 2, and are firmly connected to the outer wall of the clamp 2 by welding. Each support frame 3 extends outward from the clamp 2 to form a stable support structure. Two support frames 3 are welded to the left clamp 21 and the right clamp 22 respectively. These four support frames 3 are distributed in a cross shape with the clamp 2 as the center, which not only enhances the overall rigidity of the structure, but also ensures the uniform distribution of the supporting force.

[0025] The outer end of the support frame 3, away from the clamp 2, is provided with a support foot 5. The support foot 5 is placed directly on the ground, providing stable vertical support for the entire fixed steel support structure.

[0026] This precast pipe pile 1 fixed steel support structure, through the organic combination of clamp 2, support frame 3 and support foot 5, forms a stable and reliable support system, effectively solving the stability problem of precast pipe pile 1 during construction and use, and providing a strong guarantee for the safe and smooth progress of the project.

[0027] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the support frame 3 includes a fixing rod 31 perpendicular to the bottom of the outer wall of the clamp 2. The fixing rod 31 provides solid vertical support for the entire support frame 3. During installation, the lower end of the fixing rod 31 is usually firmly fixed to the ground embedded part or floor by welding, while the upper end is tightly connected to the outer wall of the clamp 2 to form a stable support system.

[0028] To further enhance the stability and load-bearing capacity of the support frame 3, a support rod 32 is inclinedly installed on the fixed rod 31, with the outer end of the support rod 32 connected to the outer wall of the clamp 2. One end of the support rod 32 is connected to the middle or upper part of the fixed rod 31, while the other end extends outward and connects to the outer wall of the clamp 2, forming a triangular stable structure. This not only improves the overall rigidity of the support frame 3 but also effectively disperses the lateral force generated by the pipe pile 1 on the support frame 3, preventing deformation or damage to the structure due to uneven stress.

[0029] Four support frames 3 are evenly distributed in a cross shape on the outer wall of the clamp 2. Each support frame 3 includes a fixed rod 31 and an inclined support rod 32. This not only ensures that the supporting force is evenly distributed around the pipe pile 1, but also effectively improves the overturning resistance and stability of the entire fixed steel support structure. When bearing loads from the pipe pile 1 and the structure above, the four support frames 3 can work together to resist lateral and vertical forces, ensuring the stable support and safe use of the pipe pile 1.

[0030] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the fixing rod 31, the support rod 32 and the clamp 2 form a triangular support.

[0031] Specifically, the fixing rod 31, the support rod 32, and the clamp 2 are combined to form a stable and efficient triangular bracket, providing a solid and reliable support system for fixing the precast pipe pile 1.

[0032] The triangular support structure, consisting of the fixing rod 31, the support rod 32, and the clamp 2, fully utilizes the stability principle of a triangle, giving the entire support system excellent anti-overturning and load-bearing capacity. When bearing loads from the pipe pile 1 and the structure above, the triangular support structure can effectively distribute the load to each support component and safely transfer it to the foundation through a reasonable mechanical transfer path.

[0033] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a connecting ring 6 is provided at the outer end of the fixing rod 31 away from the clamp 2, and the support foot 5 passes through the connecting ring 6 and is placed on the ground.

[0034] Specifically, a connecting ring 6 is provided at the outer end of the fixing rod 31 away from the clamp 2, which not only enhances the flexibility of the structure, but also greatly improves the ease of installation and stability of the support foot 5.

[0035] The combination of the fixing rod 31, the connecting ring 6, and the supporting leg 5 gives the precast pipe pile 1 fixed steel support structure many advantages. First, the design of the connecting ring 6 enables the rapid installation and disassembly of the supporting leg 5, improving construction efficiency. Second, the adjustability between the connecting ring 6 and the supporting leg 5 allows the support to adapt to support requirements at different heights and angles. Finally, the stable support of the supporting leg 5 ensures that the entire support remains stable under heavy loads, effectively preventing lateral displacement and settlement of the pipe pile 1.

[0036] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the support foot 5 includes a fixing plate 51 placed on the ground. The fixing plate 51 is designed as a flat rectangular or circular plate structure, and is usually made of high-strength, corrosion-resistant steel to ensure that it can maintain the integrity and stability of the structure under long-term and enormous pressure. The fixing plate 51 increases the friction between the support foot and the ground, improves the anti-slip ability, and can adapt to minor unevenness of different ground surfaces to a certain extent, ensuring that the support foot 5 can be placed firmly on the ground.

[0037] A fixing cylinder 53 is positioned perpendicular to the center of the fixing plate 51. The fixing cylinder 53 is a hollow cylindrical structure, and its inner and outer diameters are calculated to match the size of the subsequently inserted connecting rod 52, ensuring a proper fit and connection between the two. The fixing cylinder 53 is firmly connected to the fixing plate 51 by welding or integral molding, forming an inseparable whole.

[0038] A connecting rod 52 is inserted into the fixed cylinder 53. The connecting rod 52 is designed as a slender cylindrical rod structure, which can be smoothly inserted into the fixed cylinder 53. The connecting rod 52 is also made of high-strength steel, and its surface is specially treated (such as galvanizing, painting, etc.) to improve its corrosion resistance and service life. One end of the connecting rod 52 is provided with a connection structure (such as threads, grooves, etc.) that matches other parts of the support frame 3 (such as the connecting ring 6 on the fixed rod 31) to facilitate a reliable connection with the upper support structure. During installation, the connecting rod 52 is inserted into the fixed cylinder 53 and is firmly fixed to the fixed cylinder 53 by fasteners or welding to form a complete support system.

[0039] The fixing plate 51 allows the support leg 5 to be easily placed on various ground surfaces without complicated ground preparation; the plug-in design of the fixing cylinder 53 and the connecting rod 52 enables quick connection and disassembly of the support leg 5 to the upper support structure, facilitating adjustment and maintenance during construction. Furthermore, all components of the support leg 5 can be customized and replaced according to actual needs, further improving the adaptability and economy of the entire fixed steel support structure.

[0040] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the connecting ring 6 is a cylinder, and the connecting rod 52 is a rod with a smooth surface.

[0041] Specifically, the cylindrical shape of the connecting ring 6 has many mechanical advantages, as it can evenly distribute the axial force and possible lateral force from the connecting rod 52, avoid local stress concentration, and thus greatly improve the reliability and durability of the connection.

[0042] The connecting rod 52 is designed with a smooth surface, which can significantly reduce the frictional resistance when the connecting rod 52 is inserted into and pulled out of the connecting ring 6, making the installation and disassembly process easier and more convenient, and greatly improving construction efficiency.

[0043] When the pipe pile 1 is subjected to loads generated by the structure above, the load is transferred to the connecting ring 6 through the fixing rod 31. The connecting ring 6 evenly distributes the load to the connecting rod 52, which then transfers the load to the support leg 5. Finally, the support leg 5 safely transfers the load into the foundation. In this process, the cylindrical shape of the connecting ring 6 and the smooth surface of the connecting rod 52 play an important role in ensuring smooth and stable load transfer.

[0044] Since the connecting rod 52 and the connecting ring 6 are connected by a plug-in method, when encountering changes in geological conditions or construction errors, the support can be adjusted and optimized by adjusting the insertion depth of the connecting rod 52 or by replacing the connecting rod 52 with one of different lengths, so as to ensure that the support always maintains a stable support state.

[0045] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connecting ring 6 is a hexagonal nut, and the connecting rod 52 is a threaded rod.

[0046] Specifically, the connecting ring 6 is designed in the shape of a hexagonal nut. The six equal sides allow torque to be applied from multiple directions with the help of tools such as wrenches when tightening or loosening the connecting rod 52, greatly increasing the convenience and efficiency of operation. At the same time, the hexagonal structure can distribute stress more evenly when bearing torque, avoiding nut damage or deformation caused by stress concentration, thereby improving the reliability and durability of the connecting ring 6.

[0047] The internal thread of the connecting ring 6 has good self-locking properties, which can prevent the connecting rod 52 from loosening automatically when subjected to axial force. The selection of the thread pitch is optimized according to the diameter and load-bearing capacity of the connecting rod 52 to ensure that the connecting rod 52 can be quickly installed and removed while meeting the strength requirements.

[0048] The connecting rod 52 is designed as a threaded rod, which determines the connection strength and reliability between the connecting rod 52 and the connecting ring 6. The thread profile, pitch, and precision match the internal thread of the connecting ring 6 to ensure that the two can fit together and achieve efficient force transmission.

[0049] When the pipe pile 1 is subjected to loads generated by the superstructure, the load is transferred to the connecting ring 6 through the fixing rod 31. The connecting ring 6, through its internal thread, tightly engages with the thread of the connecting rod 52, evenly transferring the load to the connecting rod 52. The connecting rod 52 then transfers the load to the support leg 5, which ultimately safely transfers the load into the foundation. In this process, the hexagonal structure and internal thread design of the connecting ring 6, as well as the threaded rod design of the connecting rod 52, play a crucial role in ensuring smooth and stable load transfer.

[0050] Combination Figure 1, Figure 2 , Figure 3 and Figure 5 As shown, a crossbar 7 is provided at the top of the connecting rod 52.

[0051] Specifically, the crossbar 7 is typically a horizontally extending rod, the length and diameter of which are designed according to actual engineering requirements. The connection between the crossbar 7 and the connecting rod 52 is usually a welded connection. Welded connections allow the two to form a single unit, providing high connection strength and rigidity.

[0052] The main function of the crossbar 7 is to facilitate the insertion or removal of the connecting rod 52 in the connecting ring 6 and the fixing cylinder 53. The installer only needs to grasp the crossbar 7 with both hands and rotate it to pull the connecting rod 52 upward or insert it downward.

[0053] This invention represents a preferred embodiment of the present invention, but its scope of protection is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this invention, based on the technical solution and inventive concept of this invention, shall be covered within the scope of protection of this invention.
