Technical Field
[0001] This utility model relates to the field of building construction technology, and more specifically to a rebar positioning device for pile head flared openings. Background Technology
[0002] In construction engineering, pile foundations are widely used as an important foundation type. When connecting pile heads to structures such as pile caps, the pile head reinforcement needs to be adjusted to a trumpet shape and accurately positioned according to design requirements to ensure the stability and reliability of the structural connection. However, there are many problems in the current construction process: 1. Traditional positioning methods rely heavily on the experience of construction workers. Manually measuring and adjusting the position of the reinforcement makes it difficult to guarantee the accuracy and consistency of the reinforcement positioning, leading to deviations in parameters such as the angle and spacing of the pile head reinforcement from the design requirements, affecting the structural load-bearing performance and stability; 2. The operation process is cumbersome, requiring a large amount of manpower and time, resulting in low efficiency and hindering project progress; 3. Some positioning tools are often designed for specific pile types and reinforcement specifications, lacking versatility. When facing different projects or different specifications of trumpet-shaped reinforcement in the pile head, it is necessary to remake or replace the positioning tools, increasing construction costs and management difficulty.
[0003] Therefore, there is an urgent need for a pile head bell-shaped rebar positioning device that can improve positioning accuracy, simplify operation procedures, and is universal. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a pile head bell-shaped rebar positioning device to solve the problems of low positioning accuracy, complicated operation and poor versatility in the existing pile head bell-shaped rebar positioning process.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.
[0006] The pile head bell-shaped rebar positioning device includes an upper positioning ring and a lower positioning ring, which are parallel and concentrically arranged. The diameter of the upper positioning ring is larger than that of the lower positioning ring. Several columns for connecting the upper and lower positioning rings are inserted between them. Several clamping plates for fixing the rebar are evenly arranged on the outer periphery of the lower positioning ring of the upper positioning ring. The outer side of the clamping plates has positioning grooves for clamping the rebar. The bottom end of the lower positioning ring is provided with an adjustable leg for adjusting the height of the positioning device. The bottom end of the adjustable leg is provided with a support foot. Positioning holes for connecting columns are respectively opened on the upper and lower end faces of the upper and lower positioning rings.
[0007] To further optimize the technical solution, rubber blocks are embedded on both the upper and lower end faces of the upper and lower positioning rings, and positioning holes are opened on the rubber blocks.
[0008] To further optimize the technical solution, the card plate is set on the outside of the upper and lower positioning rings via a U-shaped frame, and the card plate and the U-shaped frame are connected by a pivot.
[0009] To further optimize the technical solution, the adjustable support leg includes a support leg inserted into the positioning hole at the bottom of the lower positioning ring, and an adjustment leg is connected to the lower part of the support leg by a thread, with the support foot located at the bottom end of the adjustment leg.
[0010] To further optimize the technical solution, a rubber pad is provided on the bottom surface of the support foot to increase the friction of the support foot.
[0011] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.
[0012] The pile head bell-shaped rebar positioning device provided by this utility model, through the cooperation of the positioning ring assembly and the rebar positioning mechanism, can accurately determine the position and angle of the pile head bell-shaped rebar, effectively improve the positioning accuracy, ensure the consistency of the pile head rebar with the design requirements, and enhance the stress performance and stability of the structure.
[0013] The size of the positioning ring assembly in this invention can be adjusted according to different pile types and rebar specifications. The adjustable design of the support legs enables it to adapt to construction environments with different heights and ground conditions. The slot angle of the rebar positioning mechanism can also be adjusted, which enhances the adaptability of the device to different projects and rebar positioning requirements, and reduces construction costs and management difficulty.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0017] Pile head bell-shaped rebar positioning device, combined with Figures 1 to 2 As shown, it includes an upper positioning ring 1 and a lower positioning ring 2. The upper positioning ring 1 and the lower positioning ring 2 are parallel to each other and concentrically arranged. The upper positioning ring is located above the lower positioning ring. The diameter of the upper positioning ring is larger than the diameter of the lower positioning ring. Several columns 5 are inserted between the upper positioning ring 1 and the lower positioning ring 2 to connect the upper positioning ring 1 and the lower positioning ring 2, so that the upper positioning ring and the lower positioning ring form an integral structure.
[0018] Rubber blocks 3 are embedded on both the upper and lower end faces of the upper positioning ring 1 and the lower positioning ring 2. The rubber blocks 3 have positioning holes 4 for inserting the column 5 to achieve splicing of the upper and lower positioning rings. The insertion method allows the positioning device to be adjusted according to the size of the pile head. The appropriate size of the upper and lower positioning rings can be selected according to the diameter of the pile head, and different numbers of positioning rings can be spliced according to the height of the pile head to enhance the stability of the positioning device.
[0019] Several clamping plates 7 are evenly arranged on the outer periphery of the upper positioning ring 1 and the lower positioning ring 2. Positioning slots are provided on the outer side of each clamping plate 7 to clamp the reinforcing bars and achieve positioning. The clamping plates 7 are set on the outer side of the upper positioning ring 1 and the lower positioning ring 2 via a U-shaped frame 6. The clamping plates 7 and the U-shaped frame 6 are connected by a pivot. The clamping plates 7 are set on the U-shaped frame via the pivot, allowing for adjustable angle between the clamping plates and the U-shaped frame, thereby enabling angle adjustment of the positioned reinforcing bars.
[0020] The bottom end of the lower positioning ring 2 is provided with a support foot 10 to support the positioning device. A rubber pad 11 is provided on the bottom surface of the support foot 10 to increase the friction of the support foot and improve the stability of the positioning device.
[0021] The support foot 10 is mounted on the lower positioning ring 2 via an adjustable leg. The adjustable leg includes a support leg 8 inserted into the positioning hole at the bottom of the lower positioning ring 2. An adjustment leg 9 is threadedly connected to the lower part of the support leg 8. The support foot 10 is located at the bottom end of the adjustment leg 9. The height and level of the positioning device can be adjusted by adjusting the length of the adjustment leg.
[0022] This invention relates to a method for constructing pile head reinforcement. During the construction of pile head reinforcement, appropriate size and number of positioning rings are selected based on the pile head dimensions. After connecting these rings to a column, the positioning device is placed at the pile head position. The adjusting legs are rotated to ensure the positioning device is level and at the appropriate height. The flared reinforcement bars at the pile head are then inserted one-to-one into the positioning slots on the side plate, completing the initial positioning of the reinforcement bars. Subsequent binding and fixing operations are then performed. After construction is completed, the positioning device is disassembled for future use.
