Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a building pile foundation anti-buoyancy structure. Background Technology

[0002] In the field of building construction, pile foundation anti-buoyancy structures are key devices to ensure that the reinforcing cage remains vertically stable under the action of concrete pouring and groundwater buoyancy.

[0003] In existing technologies, the design of anti-buoyancy structures mostly relies on gravity pressing or welding fixation, but the following problems still exist:

[0004] Welding or bolting requires frequent adjustments and is susceptible to corrosion, resulting in low construction efficiency. Furthermore, welded fixed structures are not removable, making later maintenance difficult and increasing project costs. While gravity block pressing is simple, it is bulky and cannot flexibly adjust the pressure distribution. Utility Model Content

Detailed Implementation

[0030] 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.

[0031] Example 1:

[0032] Please see Figures 1-4 In this embodiment of the utility model, a building pile foundation anti-buoyancy structure includes a protective casing 1. The top of the protective casing 1 is detachably fixed with multiple sets of anti-buoyancy components 3. The multiple sets of anti-buoyancy components 3 are used to vertically limit the steel cage 2 at the upper position of the steel cage 2 to achieve the purpose of anti-buoyancy.

[0033] The anti-buoyancy component 3 includes a top plate 4, a locking component is fixedly installed on the bottom surface of the top plate 4, and a limiting component is fixedly installed on the top surface of the top plate 4.

[0034] The locking assembly includes a first limiting plate 5 and a second limiting plate 9. The first limiting plate 5 is fixedly installed at the bottom end of the top plate 4, and the second limiting plate 9 is fixedly installed at the middle of the bottom surface of the top plate 4.

[0035] An arc-shaped contact plate 6 is provided between the second limiting plate 9 and the first limiting plate 5. The top surface of the arc-shaped contact plate 6 slides in contact with the bottom surface of the top plate 4. A screw 7 is rotatably connected to the side of the arc-shaped contact plate 6 away from the second limiting plate 9. A knob 8 is fixedly installed at the end of the screw 7 away from the arc-shaped contact plate 6 after it is threaded through the first limiting plate 5.

[0036] The bottom end of the limiting plate 5 is fixedly connected with a stabilizing component.

[0037] When the anti-buoyancy component 3 and the protective casing 1 are in a fixed connection, the second limiting plate 9 is located inside the protective casing 1, the first limiting plate 5 is located outside the second limiting plate 9, the arc-shaped contact plate 6 is located between the protective casing 1 and the first limiting plate 5, and the arc-shaped contact plate 6 is in extrusion contact with the protective casing 1.

[0038] The inner arc surface of the arc-shaped contact plate 6 is covered with a rubber layer.

[0039] The limiting component includes two guide rods 10 that are vertically fixedly installed on the top surface of the top plate 4. The two guide rods 10 are located at the end away from the limiting plate 5. A connecting plate 14 is fixedly connected between the top ends of the two guide rods 10. A screw 12 is rotatably installed between the connecting plate 14 and the top surface of the top plate 4. A knob 15 is fixedly installed after the top end of the screw 12 rotates through the connecting plate 14.

[0040] A lifting platform 13 is installed on the screw 12 with a through thread, and the lifting platform 13 is slidably connected to the two guide rods 10.

[0041] Two symmetrically distributed pressure rollers 11 are fixedly installed on the side of the lifting platform 13 away from the limiting plate 5.

[0042] When using this utility model:

[0043] Multiple anti-buoyancy components 3 are detachably installed at the top of the protective sleeve 1. Specifically, the core of the anti-buoyancy component is the top plate 4, and the locking component at its bottom forms a clamping space through the limiting plate 5 and the limiting plate 9. During operation, rotating the knob 8 drives the screw 7 to slide the arc-shaped contact plate 6 towards the protective sleeve, achieving a fastening effect through the compression contact between the arc-shaped contact plate 6 and the outer wall of the protective sleeve 1. The rubber layer on the inner arc surface of the arc-shaped contact plate 6 increases friction and protects the surface of the protective sleeve 1.

[0044] Therefore, this utility model, through the setting of the locking component, enables quick assembly and disassembly between the anti-buoyancy component 3 and the protective casing 1, improving ease of use and adapting to the needs of different construction scenarios. The adjustment via knob 8 simplifies operation and improves operational efficiency.

[0045] In the limiting assembly, the rotating knob 15 drives the screw 23 to rotate, causing the lifting platform 13 to slide up and down along the guide rod 10. The pressure roller 11 on the side of the lifting platform 13 adjusts its height accordingly, pressing the top of the steel cage 2, thereby achieving the purpose of anti-buoyancy.

[0046] Therefore, the height of the pressure roller 11 is precisely controlled by the knob 2 15 in the limiting component, which can adapt to different steel cages 2, and the symmetrically distributed pressure rollers 11 ensure uniform force and prevent the steel cage 2 from tilting or floating.

[0047] Therefore, in this invention, multiple sets of anti-buoyancy components 3 are evenly distributed at the top of the casing 1, the locking component fixes the casing, and the limiting component presses down on the reinforcing cage, thus limiting the vertical displacement of the reinforcing cage under the action of concrete pouring or groundwater buoyancy. Its quick-assembly and disassembly design improves construction efficiency.

[0048] Example 2:

[0049] Please see Figure 4 Based on embodiment 1, the stabilizing component is used to improve the stability of the casing 1. The stabilizing component includes an extension plate 16 that is fixedly connected to the bottom end of the limiting plate 5. The extension plate 16 is vertically arranged with the limiting plate 5.

[0050] A fixing cone 17 is installed through the top surface of the extension plate 16 at the end away from the limiting plate 5.

[0051] During installation, the fixing cone 17 is hammered or pressed into the foundation, forming a double fixation with the casing 1. The fixing cone 17 penetrates deep into the foundation, effectively preventing the casing 1 from shifting due to external forces or soil loosening, and enhancing the overall anti-overturning capacity.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
