Description

Technical Field

[0001] This utility model relates to the technical field of pile foundation pile head reinforcement structure, specifically a pile head reinforcement structure for building pile foundation. Background Technology

[0002] In modern building construction, piling is a crucial step in ensuring the stability and safety of a building. After piling is completed, the pile driver head is usually exposed above the ground to facilitate connection with other components such as main beams, thus providing reliable support for the building.

[0003] However, in actual construction, pile foundation jacks face numerous problems. On the one hand, due to accidental contact during operation, the pile foundation jacks are prone to cracking, which not only affects the structural strength and stability of the pile foundation but may also adversely impact the quality of the entire building. On the other hand, during construction, the pile foundation jacks may fail to meet design standards for various reasons, necessitating reinforcement.

[0004] Currently, a common method for reinforcing pile foundation jacking heads is to fit a rubber waterproof ring around the outside of the jacking head and then inject concrete into the ring. The concrete then hardens, reinforcing the pile foundation. In addition to its waterproofing function, this rubber waterproof ring also provides some protection for the pile foundation jacking head.

[0005] However, most existing rubber waterproof sleeves are made in one piece. When using these one-piece molded rubber waterproof sleeves, the corresponding model needs to be selected based on the specific dimensions of the pile driver head. Since pile driver head dimensions may vary, this results in poor versatility for the rubber waterproof sleeves. When the pile driver head size does not match the existing rubber waterproof sleeve, it not only increases construction difficulty but may also affect the reinforcement and waterproofing effects, and may even necessitate the custom-made rubber waterproof sleeve, thereby increasing construction costs and extending the construction period.

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a pile head reinforcement structure for building foundations, which solves the problems mentioned in the background section.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a pile head reinforcement structure for building foundations, including splicing joints, wherein a plurality of splicing joints are provided, each splicing joint including a sheet, one end of which has a slot and the other end is provided with a matching insert strip, and the sheet is made of flexible material, wherein the plurality of splicing joints are sequentially inserted to form a ring shape.

[0010] Furthermore, a recess is provided on the outer side of the tablet, so that the thickness of the tablet at the recess is less than the thickness of its edge.

[0011] Furthermore, the slot is T-shaped.

[0012] Furthermore, the flexible material is rubber.

[0013] Furthermore, this also includes clamps.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a pile head reinforcement structure for building foundations, which has the following beneficial effects:

[0016] The pile head reinforcement structure for this building foundation uses splicing pieces that can be selected in matching quantities according to the diameter of the pile head. These pieces are then interlocked to form a ring shape that fits onto the pile head. This allows for flexible adaptation to pile heads of different diameters, making it highly versatile. It avoids the limitations of traditional one-piece molded rubber waterproof sleeves, which require selecting the corresponding model based on the specific pile head size. This reduces the difficulties caused by mismatched waterproof sleeve sizes during construction, saves the cost and time of re-customization, and improves construction efficiency.

[0020] 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.

[0021] Please see Figs. 1-2This utility model discloses a pile head reinforcement structure for building foundations, comprising splicing plates. Several splicing plates are provided as needed. Each splicing plate includes a plate body 1, with a T-shaped groove at one end and an insert 2 integrally formed with the other end of the splicing plate. The insert 2 matches the groove. The plate body 1 is made of a flexible material, such as rubber, and a recess 4 extending from the top to the bottom is formed on the outer wall of the plate body 1. This makes the thickness of the plate body 1 thinner at the recess 4 compared to its edge thickness. Because the recess 4 is thinner than the plate body 1, its cross-sectional moment of inertia is smaller, resulting in lower bending stiffness. When an external force is applied to the plate body 1 to cause it to bend, stress analysis shows that a relatively large stress concentration will occur at the recess 4.

[0022] Stress concentration refers to the phenomenon where a significant increase in stress occurs in a localized area due to abrupt changes in the geometry or dimensions of a stressed component. The abrupt change in thickness of the recess 4 is such a geometrical change, which leads to stress concentration in that area. Under the influence of stress concentration, the recess 4 will be the first to meet the material's yield condition, thus initiating plastic deformation, i.e., bending.

[0023] Furthermore, because the recessed portion 4 is thin, the intermolecular forces within it are relatively weak. Compared to thicker parts such as the edges of the sheet 1, it is more difficult to resist deformation caused by external forces. Therefore, when bending the sheet 1, bending is more likely to occur in the recessed portion 4. On the other hand, the edges of the sheet 1 are thicker, have greater bending stiffness, and exhibit less stress concentration, making bending more difficult.

[0024] This causes the splicing piece to bend primarily at the recessed part 4 during assembly, reducing the stress on the insert 2 after it enters the slot 3.

[0025] Select the appropriate number of splicing pieces according to the diameter of the pile head, and interlock them to form a ring shape. Then, fit the ring onto the pile head to match pile heads of different diameters.

[0026] The device also includes a clamp 5, which is fitted over the outside of the assembly when the splice pieces are bent during assembly. When in use, the clamp 5 is adjusted to shrink, causing the splice pieces on the assembly to bend, so that they can be inserted and installed later.

[0027] In summary, for the pile head reinforcement structure of this building foundation, splicing pieces and clamps 5 should be prepared according to requirements for subsequent assembly.

[0028] During assembly, starting with one splicing piece, insert the splicing piece insert 2 into its slot 3, and then install them in sequence. When the remaining splicing pieces are installed, put the partially assembled splicing pieces into the clamp 5.

[0029] Use tools to adjust clamp 5, causing clamp 5 to contract, which in turn causes the assembled splicing pieces to tend towards a circle. Then gradually tighten clamp 5 and install the splicing pieces until the splicing pieces complete the circular insertion and match the pile head.

[0030] Then use tools to adjust clamp 5, enlarge the diameter of clamp 5, and remove it from the assembled splice piece.

[0031] The assembled splice pieces are fitted onto the pile head, and concrete is injected into the pile until it hardens.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
