Description

Technical Field

[0001] This application belongs to the field of building construction technology, specifically a fixed structure for pile foundations used in building construction. Background Technology

[0002] Pile foundation embedment structures for building construction are an important part of the field of building engineering technology, mainly used to improve the stability and seismic performance of buildings.

[0003] For example, application CN217517552U discloses a pile foundation embedding structure for building construction, including a ground surface, an embedding groove on the ground surface, an embedding platform installed in the embedding groove, a plurality of limiting bolts penetrating the embedding platform, each limiting bolt extending into the ground surface, an installation opening penetrating the embedding platform, a pile foundation installed in the installation opening, and two limiting mechanisms on the embedding platform. Each limiting mechanism includes a lever penetrating the embedding platform and rotatably connected thereto, with a first bevel gear fixedly connected to the bottom of the lever. The first bevel gear meshes with a second bevel gear, and the second bevel gear is fixedly connected to a first threaded rod, which is rotatably connected to the embedding platform. This utility model uses a limiting plate to limit the pile foundation, ensuring its stability; by inserting a threaded installation cylinder into the limiting groove, the pile foundation is further limited, making the pile foundation firmly embedded and securely installed.

[0004] However, in this application, the push rod and hand-cranked screw are used to tighten the top and bottom of the pile foundation, which cannot align the bottom of the pile foundation. This may cause the placed pile foundation to tilt. If the pile foundation is placed for a long time, it may loosen due to natural shaking. Utility Model Content

[0005] The purpose of this application is to provide a fixed structure for pile foundations used in building construction in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: A fixed structure for a pile foundation for building construction includes a main foundation column of the equipment. A support column is fixedly connected to the top of the foundation column. A threaded sliding column is rotatably connected to the outer side of the support column. A sliding support ring is slidably connected to the outer side of the threaded sliding column. Fixed rotating blocks are fixedly connected to the upper sides of both sides of the sliding support ring. An upper push rod is rotatably connected to the inner side of the fixed rotating block. An upper fastening block is rotatably connected to the upper push rod. A limit column is fixedly connected to the top of the support column. An upper transmission gear is fixedly connected to the lower side of the limit column. A circular power gear is slidably connected to the lower side of the upper transmission gear. A lower transmission gear is slidably connected to the lower side of the circular power gear. A threaded sliding column is fixedly connected to the lower side of the lower transmission gear.

[0007] By adopting the above technical solution, during the operation of the equipment, the foundation column is fixed to the ground, and then the pile foundation is placed into the pile foundation placement groove. The bottom of the pile foundation placement groove will press down the placement platform, compressing the spring. The placement platform moves downward, causing the push blocks fixed to both sides of the placement platform to slide down along the push block sliding groove. During the downward movement, it will push the lower push rod to move outward. By fixing the rotating column, it can drive the lower fastening block inward, thereby using the weight of the pile foundation from below to fix the pile foundation and keep the bottom of the pile foundation centered. After placement, it can be manually... The rotating pile foundation placement groove drives the circular power gear to rotate. The rotation of the circular power gear, through the upper and lower transmission gears, drives the push block sliding groove to rotate on the outside of the support column. The rotation of the push block sliding groove causes the sliding support ring to rise. Through the upper push rod and upper fastening block, the column pile foundation can be fixed from above. When the upper structure of the pile foundation is heavier, it will cause the overall structure to sink slightly. During the sinking process, the soil surface will squeeze the sliding support ring to rise, which can further secure the pile foundation. By increasing the contact area at the bottom, sinking can also be reduced.

[0008] In a preferred embodiment, the inner sides of the foundation column, support column, and push block are provided with through pile foundation placement grooves. The pile foundation placement groove inside the foundation column is provided with an internal movable groove. The side wall of the internal movable groove is rotatably connected to a fixed rotating column. The outer side of the fixed rotating column is rotatably connected to a lower push rod. The upper part of the lower push rod is rotatably connected to a lower fastening block. The inner side of the lower push rod is provided with a push block sliding groove. The inner side of the push block sliding groove is slidably connected to a push block.

[0009] By adopting the above technical solution, the lower fastening block can be driven inward, thereby fixing the pile foundation from below using the gravity of the pile foundation.

[0010] In a preferred embodiment, a spring is fixedly connected above the bottom of the pile foundation placement groove, a placement platform is fixedly connected above the spring, and push blocks are fixedly connected to both sides of the placement platform.

[0011] By adopting the above technical solutions, the descent speed of the pile foundation can be slowed down, reducing the impact on the equipment.

[0012] In a preferred embodiment, a pile foundation is slidably connected to the top and side walls of the pile foundation placement trench, and an upper fastening block and a lower fastening block are slidably connected to the outside of the pile foundation.

[0013] By adopting the above technical solution, the pile foundation can be fixed from both above and below, making the pile foundation more stable.

[0014] In a preferred embodiment, the upper push rod has a through sliding groove in the middle, a sliding fixing block is slidably connected to the inner side of the sliding groove, and a limit post is fixedly connected to the inner side of the sliding fixing block.

[0015] By adopting the above technical solution, the upper fastening block can tightly clamp the pile foundation.

[0016] In a preferred embodiment, a rocker arm is fixedly connected to the outer side of the circular power gear.

[0017] By adopting the above technical solution, the tightness of the upper fastening block can be adjusted manually.

[0018] In a preferred embodiment, a pile foundation placement groove is slidably connected to the outer side of the placement platform.

[0019] By adopting the above technical solution, the gravity compression placement platform of the pile foundation slides down.

[0020] In a preferred embodiment, the inner side of the upper fastening block is fixedly connected with anti-slip rubber.

[0021] By adopting the above technical solution, the pile foundation can be prevented from sliding up and down.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In this application, during the operation of the equipment, the foundation column is fixed to the ground, and then the pile foundation is placed into the pile foundation placement groove. The bottom of the pile foundation placement groove will press down the placement platform, compressing the spring. The placement platform moves downward, causing the push blocks fixed to both sides of the placement platform to slide down along the push block sliding groove. During the downward movement, it will push the lower push rod to move outward. By fixing the rotating column, it can drive the lower fastening block inward, thereby using the weight of the pile foundation from below to fix the pile foundation and keep the bottom of the pile foundation centered. After placement, the pile foundation placement groove is manually rotated to drive the circular power gear to rotate. The rotation of the circular power gear will drive the threaded sliding column to rotate on the outside of the support column through the upper and lower transmission gears. The rotation of the threaded sliding column will drive the sliding support ring to rise. Through the upper push rod and the upper fastening block, the column pile foundation can be fixed from above. When the upper structure of the pile foundation is heavier, it will cause the overall structure to sink slightly. During the sinking process, the soil surface will squeeze the sliding support ring to rise, which can further tighten the pile foundation. By increasing the contact area at the bottom, sinking can also be reduced. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Example:

[0031] Reference Figure 1-4 A fixed structure for a pile foundation used in building construction includes a main foundation column 1, a support column 2 fixedly connected to the top of the foundation column 1, a threaded sliding column 25 rotatably connected to the outer side of the support column 2, a sliding support ring 3 slidably connected to the outer side of the threaded sliding column 25, fixed rotating blocks 4 fixedly connected to the upper sides of the sliding support ring 3, an upper push rod 5 rotatably connected to the inner side of the fixed rotating block 4, an upper fastening block 8 rotatably connected to the upper push rod 5, a limiting column 9 fixedly connected to the top of the support column 2, an upper transmission gear 10 fixedly connected to the lower side of the limiting column 9, a circular power gear 11 slidably connected to the lower side of the upper transmission gear 10, a lower transmission gear 12 slidably connected to the lower side of the circular power gear 11, and a threaded sliding column 25 fixedly connected to the lower side of the lower transmission gear 12. This structure can more firmly secure the pile foundation 14 and reduce settlement by increasing the contact area at the bottom.

[0032] Reference Figure 1-4During the operation of the equipment, the foundation column 1 is fixed to the ground, and then the pile foundation 14 is placed into the pile foundation placement groove 13. The bottom of the pile foundation placement groove 13 will press down the placement platform 20, compressing the spring 21. The placement platform 20 moves downward, causing the push blocks 19 fixedly connected to both sides of the placement platform 20 to slide down along the push block sliding groove 22. During the downward movement, the lower push rod 17 will be pushed to move outward in the lower direction. By fixing the rotating column 16, the lower fastening block 18 can be moved inward, so that the pile foundation 14 can be fixed from below by the gravity of the pile foundation 14, and the bottom of the pile foundation 14 is kept in the center.

[0033] Reference Figure 1-2 After placement, the pile foundation placement slot 13 is manually rotated, which drives the circular power gear 11 to rotate. The rotation of the circular power gear 11 will drive the threaded sliding column 25 to rotate on the outside of the support column 2 through the upper transmission gear 10 and the lower transmission gear 12. The rotation of the threaded sliding column 25 will drive the sliding support ring 3 to rise. The pile foundation 14 can be fixed from above by the upper push rod 5 and the upper fastening block 8. When the upper structure of the pile foundation 14 is heavier, it will cause the overall structure to sink slightly. During the sinking process, the soil surface will squeeze the sliding support ring 3 to rise, which can further tighten the pile foundation 14. By increasing the contact area at the bottom, the sinking can also be reduced.

[0034] Reference Figure 1-4 The foundation column 1, support column 2, and push block 19 have through pile placement grooves 13 on their inner sides. The pile placement groove 13 inside the foundation column 1 has an internal movable groove 15. A fixed rotating column 16 is rotatably connected to the side wall of the internal movable groove 15. A lower push rod 17 is rotatably connected to the outer side of the fixed rotating column 16. A lower fastening block 18 is rotatably connected above the lower push rod 17. A push block sliding groove 22 is formed on the inner side of the lower push rod 17, and a push block 19 is slidably connected to the inner side of the push block sliding groove 22. This allows the lower fastening block 18 to move inward, thereby fixing the pile foundation 14 from below using its gravity.

[0035] Reference Figure 1-4 A spring 21 is fixedly connected above the bottom of the pile foundation placement trench 13, and a placement platform 20 is fixedly connected above the spring 21. Push blocks 19 are fixedly connected to both sides of the placement platform 20. This can slow down the descent speed of the pile foundation 14 and reduce the impact on the equipment.

[0036] Reference Figure 1-4 A pile foundation 14 is slidably connected to the top and side walls of the pile foundation placement trench 13, and an upper fastening block 8 and a lower fastening block 18 are slidably connected to the outside of the pile foundation 14. The pile foundation 14 can be fixed from the top and the bottom respectively, making the pile foundation 14 more stable.

[0037] Reference Figure 1-2The upper push rod 5 has a through sliding groove 6 in the middle, and a sliding fixing block 7 is slidably connected to the inner side of the sliding groove 6. A limit post 9 is fixedly connected to the inner side of the sliding fixing block 7. This allows the upper fastening block 8 to tightly clamp the pile foundation 14.

[0038] Reference Figure 1 A rocker arm 24 is fixedly connected to the outer side of the circular power gear 11. The tightness of the upper fastening block 8 can be manually adjusted.

[0039] Reference Figure 1-4 The outer side of the placement platform 20 is slidably connected to the pile foundation placement groove 13. This allows the gravity of the pile foundation 14 to compress the placement platform 20 and cause it to slide down.

[0040] Reference Figure 1 The inner side of the upper fastening block 8 is fixedly connected with anti-slip rubber 23. This can prevent the pile foundation 14 from sliding up and down.

[0041] The implementation principle of the embedded structure embodiment of the pile foundation for building construction in this application is as follows:

[0042] During equipment operation, the foundation column 1 is fixed to the ground, and then the pile foundation 14 is placed into the pile foundation placement groove 13. The bottom of the pile foundation placement groove 13 will press down the placement platform 20, compressing the spring 21. The placement platform 20 moves downward, causing the push blocks 19 fixedly connected to both sides of the placement platform 20 to slide down along the push block sliding groove 22. During the downward movement, the lower push rod 17 will be pushed to move outward. By fixing the rotating column 16, the lower fastening block 18 can be moved inward, thereby using the weight of the pile foundation 14 from below to fix the pile foundation 14 and keep the bottom of the pile foundation 14 centered. After placement, the pile foundation 14 is then fixed by manually rotating the pile. The base placement groove 13 drives the circular power gear 11 to rotate. The rotation of the circular power gear 11 will drive the threaded sliding column 25 to rotate on the outside of the support column 2 through the upper transmission gear 10 and the lower transmission gear 12. The rotation of the threaded sliding column 25 will drive the sliding support ring 3 to rise. Through the upper push rod 5 and the upper fastening block 8, the column pile foundation 14 can be fixed from above. When the upper structure of the pile foundation 14 is heavier, it will cause the overall structure to sink slightly. During the sinking process, the soil surface will squeeze the sliding support ring 3 to rise, which can further tighten the pile foundation 14. By increasing the contact area at the bottom, the sinking can also be reduced.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
