Description

Technical Field

[0001] This utility model relates to the field of civil engineering pile technology, and in particular to a prestressed concrete pipe pile for high strength and durability in green building. Background Technology

[0002] Prestressed concrete pipe piles, as a key component of green building foundation engineering, are widely used due to their unique advantages. They are mainly composed of a concrete pile body, prestressed steel bars, spiral stirrups, pile tip, and end plate. By applying prestress to the steel bars, the concrete of the pile body is pre-compressed before bearing external loads, improving the crack resistance and bearing capacity of the pile body. In green buildings, prestressed concrete pipe piles are used to bear the vertical and horizontal loads of the building, reliably transferring the weight of the superstructure to the foundation and ensuring the stability of the building. Their high strength and high durability not only adapt to different geological conditions, but also effectively reduce foundation maintenance and replacement costs, meeting the needs of long-term stable operation of green buildings and providing a solid foundation for the construction of green buildings.

[0003] The existing process for connecting concrete pipe piles is cumbersome and lacks convenient and effective positioning methods, resulting in a significant amount of time being spent on complex positioning and calibration during connection, which reduces construction efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a prestressed concrete pipe pile for high strength and durability in green building, aiming to improve the problems of cumbersome connection process and complex positioning and calibration of existing concrete pipe piles, which lead to low construction efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength and durable prestressed concrete pipe pile for green building, comprising an outer cylinder, a plurality of first reinforcing bars fixedly connected inside the outer cylinder, an end cap fixedly connected to one end of the outer cylinder, a fixing member fixedly connected to the other end of the outer cylinder, a cone provided at the bottom end of the fixing member, a rotating ring rotatably connected inside the fixing member, a plurality of connecting members fixedly connected to the bottom of the rotating ring, a plurality of third fixing holes opened on the surface of the fixing member, and a load-bearing component provided inside the outer cylinder.

[0006] Preferably, the load-bearing component includes a middle cylinder, the outer wall of the middle cylinder is fixedly connected to the inner diameter of the outer cylinder, an inner cylinder is fixedly connected to the inner diameter of the middle cylinder, and uniformly distributed support ribs are fixedly connected inside the middle cylinder.

[0007] Preferably, the outer cylinder is provided with a plurality of second reinforcing bars, one end of each of the plurality of second reinforcing bars being fixedly connected to the end cap, and the other end of each of the plurality of second reinforcing bars being fixedly connected to the fixing member.

[0008] Preferably, the end cap and the top of the cone are fixedly connected to a plurality of connecting blocks, each of the connecting blocks having a first fixing hole on its surface and an installation groove on an adjacent side of each of the connecting blocks.

[0009] Preferably, the fastener has multiple screws on its outer side, and each screw is threadedly connected to an adjacent connecting block, connecting member, and fastener.

[0010] Preferably, all of the connectors slide inside the fixing member, and each of the connectors has a second fixing hole on its surface.

[0011] Preferably, one end of each of the plurality of first reinforcing bars is fixedly connected to an end cap, and the other end of each of the plurality of first reinforcing bars is fixedly connected to a fixing member.

[0012] Preferably, the end cap and the fixing member are both provided with holes, and the end cap, the fixing member and the inner cylinder are interconnected.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by assembling multiple first fixing holes with the fixing parts, and then rotating the rotating ring to drive the connecting parts to rotate, the rotating ring is locked inside the connecting block. At this time, the connecting block, the connecting parts and the fixing parts are fixed by screws, thereby enabling the outer cylinder and the bottom cone to be quickly spliced ​​and fixed, or multiple outer cylinders to be fixed together. This solves the problem of needing professional tools or complex positioning calibration when connecting two outer cylinders.

[0015] 2. In this utility model, the glass fiber reinforced plastic support ribs effectively disperse and bear external forces, improving the resistance of the pipe pile to vertical and lateral loads. Polystyrene foam particles are used to improve thermal insulation performance and reduce heat transfer. At the same time, the structure of each layer is optimized to improve buffer performance, alleviate the impact of external forces and protect the inner and outer cylinders. This solves the problems of insufficient strength of pipe piles in the prior art, which make them prone to cracking, damage or even breakage under complex loads, as well as the structural damage caused by external forces affecting service life.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-3 The present invention provides an embodiment of a high-strength and durable prestressed concrete pipe pile for green building, comprising an outer cylinder 1, a plurality of first reinforcing bars 9 fixedly connected inside the outer cylinder 1, an end cap 2 fixedly connected to one end of the outer cylinder 1, a fixing member 6 fixedly connected to the other end of the outer cylinder 1, a cone 17 provided at the bottom end of the fixing member 6, a rotating ring 7 rotatably connected inside the fixing member 6, a plurality of connecting members 10 fixedly connected to the bottom of the rotating ring 7, a plurality of third fixing holes 12 opened on the surface of the fixing member 6, and a load-bearing component provided inside the outer cylinder 1.

[0024] Specifically, the outer cylinder 1 is used to bear part of the upper load, the first steel bar 9 is used to enhance the tensile and bending resistance of the outer cylinder 1, and work together with the outer cylinder 1 to improve the overall structural strength of the pipe pile, and to cope with vertical and lateral loads. The cone 17 is located at the bottom of the fixing member 6. When the outer cylinder 1 is driven into the foundation, it penetrates the soil layer, reduces resistance, and increases the contact area with the foundation soil. The rotating ring 7 is rotatably connected in the fixing member 6. When rotating, it drives the bottom connecting member 10 to rotate, thereby quickly fixing the outer cylinder 1 to the cone 17 or multiple outer cylinders 1.

[0025] Reference Figure 4 The load-bearing component includes a middle cylinder 13, the outer wall of the middle cylinder 13 is fixedly connected to the inner diameter of the outer cylinder 1, the inner diameter of the middle cylinder 13 is fixedly connected to an inner cylinder 15, and the middle cylinder 13 is fixedly connected to evenly distributed support ribs 14.

[0026] Specifically, the outer cylinder 1 possesses high strength and durability, directly bearing the loads from the superstructure and various forces from the external environment, such as vertical pressure and lateral earth pressure. It also provides a stable external frame for the entire pipe pile, protecting the internal structure from external physical damage. The inner cylinder 15 assists in load-bearing, sharing some of the load with the middle cylinder 13 and outer cylinder 1. It also works in conjunction with the support ribs 14 inside the middle cylinder 13 to further enhance the overall structural stability of the pipe pile. The middle cylinder 13 is made of polystyrene foam particles, effectively reducing heat transfer between the inside and outside of the pipe pile, meeting the energy-saving requirements of green buildings. Its relatively light weight, while maintaining a certain structural strength, reduces the weight of the pipe pile itself, facilitating construction and installation. The support ribs 14 are made of glass fiber reinforced plastic, effectively enhancing the structural stability of the middle cylinder 13 and helping it better withstand pressure.

[0027] Reference Figure 4 The outer cylinder 1 is provided with a plurality of second steel bars 16. One end of each of the plurality of second steel bars 16 is fixedly connected to the end cap 2, and the other end of each of the plurality of second steel bars 16 is fixedly connected to the fastener 6.

[0028] Specifically, multiple second reinforcing bars 16 are installed inside the outer cylinder 1 to connect the end cap 2, the outer cylinder 1 and the fixing member 6, thereby improving the overall structural strength of the pipe pile. This allows the pipe pile to distribute stress more evenly when subjected to vertical loads, preventing excessive local stress from causing structural damage. When dealing with lateral forces, it can enhance the deformation resistance of the pipe pile and ensure that the pipe pile maintains good stability under complex stress conditions.

[0029] Reference Figures 1-3 Multiple connecting blocks 3 are fixedly connected to the top of the end cap 2 and the cone 17. The surface of each connecting block 3 is provided with a first fixing hole 4, and the adjacent side of each connecting block 3 is provided with an installation groove 5.

[0030] Specifically, when it is necessary to connect the cone 17 or to splice multiple outer cylinders 1, multiple first fixing holes 4 are inserted into the bottom of the fixing member 6. At this time, rotating the rotating ring 7 drives the connecting member 10 to rotate. The connecting member 10 is engaged with the connecting block 3 through the mounting groove 5, thereby realizing the rapid splicing of the parts that need to be spliced.

[0031] Reference Figure 1 and Figure 3 Multiple screws 8 are provided on the outside of the fixing member 6, and the multiple screws 8 are threadedly connected to the adjacent connecting block 3, connecting member 10 and fixing member 6.

[0032] Specifically, after rotating the rotating ring 7 to the appropriate position, the first fixing hole 4, the second fixing hole 11 and the third fixing hole 12 are connected to each other. The screw 8 passes through the first fixing hole 4, the second fixing hole 11 and the third fixing hole 12, thereby fixing the connecting block 3, the fixing member 6 and the connecting member 10.

[0033] Reference Figure 3 Multiple connectors 10 slide inside the fixing member 6, and multiple connectors 10 have second fixing holes 11 on their surfaces.

[0034] Specifically, when the user rotates the rotating ring 7, it causes the connector 10 to rotate. At this time, the connector 10 and the mounting groove 5 are engaged with each other. The first fixing hole 4, the second fixing hole 11 and the third fixing hole 12 are the same size and are all used for the screw 8 to pass through and fix the connecting block 3, the fixing member 6 and the connector 10.

[0035] Reference Figure 4 One end of each of the multiple first reinforcing bars 9 is fixedly connected to the end cap 2, and the other end of each of the multiple first reinforcing bars 9 is fixedly connected to the fastener 6.

[0036] Specifically, multiple first reinforcing bars 9 connect the end cap 2 and the fixing member 6, enhancing the stability of the structure at both ends of the outer cylinder 1. This allows the force to be transmitted more evenly when the outer cylinder 1 is subjected to vertical and lateral loads, preventing the end cap 2 and the fixing member 6 from detaching from the outer cylinder 1 and improving the overall bearing capacity of the pipe pile.

[0037] Reference Figure 4 Both the end cap 2 and the fixing member 6 have holes on their surfaces, and the end cap 2, the fixing member 6 and the inner cylinder 15 are interconnected.

[0038] Specifically, holes are made on the surfaces of the end cap 2 and the fastener 6 and are interconnected with the inner cylinder 15, which facilitates wiring or the arrangement of functional components inside the pipe pile to meet diverse building needs. It also promotes internal air circulation, reduces moisture accumulation to prevent corrosion, and is conducive to construction and maintenance.

[0039] Working principle: If splicing cone 17 or multiple outer cylinders 1, insert the first fixing hole 4 into the bottom of the fixing part 6, rotate the rotating ring 7 to drive the connector 10 to engage with the connecting block 3 through the mounting groove 5, and then use screws 8 to pass through the first fixing hole 4, the second fixing hole 11 and the third fixing hole 12 to quickly fix the connecting block 3, the fixing part 6 and the connector 10.

[0040] The first reinforcing bar 9 and the second reinforcing bar 16 connect the end cap 2 and the fastener 6, which improves the stability of both ends of the outer cylinder 1 and the overall load-bearing capacity, and evenly distributes stress. The polystyrene foam particles of the middle cylinder 13 meet the energy-saving requirements of green building and reduce weight for easy construction.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
