Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a coordinate positioning and elevation reflection device for pile foundation steel cages. Background Technology

[0002] During the construction of pile foundation reinforcement cages, especially for pile foundations at a certain depth underground, it is often difficult to detect the elevation and coordinate positioning of the pile head when lowering the last section of the reinforcement cage. This leads to a large positional and elevation deviation of the pile head during excavation. The specifications stipulate a pile position deviation of 10cm for group piles and 5cm for row piles. The allowable range of error is extremely small, and it is easy to exceed the specification requirements. When the pile foundation position deviation is large, it often requires huge treatment costs.

[0003] Traditional positioning methods can only roughly determine the pile location and elevation based on the outline of the reinforcing steel bars exposed above the mud surface. The monitoring results are not accurate enough and often lead to deviations. This phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content

[0004] The purpose of this invention is to provide a coordinate positioning and elevation feedback device for pile foundation steel cages, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pile foundation reinforcement cage coordinate positioning and elevation reflection device, including a support rod, a telescopic spring fixedly connected to the inner wall of the support rod, a telescopic rod fixedly connected to one end of the telescopic spring, a reinforcement hook fixedly connected to one end of the telescopic rod, a scale fixedly connected to the top of the support rod, a pull rope movably connected inside the support rod, and a fixing buckle fixedly connected to the top of the pull rope. By setting up the support rod, telescopic spring, telescopic rod, reinforcement hook, scale, pull rope, and fixing buckle, the position and elevation of the reinforcement cage located underground and unmeasurable can be accurately transmitted to the ground, thereby enabling workers to accurately determine the position and elevation of the reinforcement cage while standing on the ground, effectively improving the convenience of elevation measurement.

[0006] Furthermore, the support rods are arranged in an "I" shape when viewed from the front and in a "Y" shape when viewed from above, which facilitates the support work.

[0007] Furthermore, the telescopic rod forms a telescopic structure with the support rod through a telescopic spring, and the telescopic rods are distributed at equal angles along the longitudinal center line of the support rod, which facilitates fixing work.

[0008] Furthermore, one end of the pull rope is connected to the telescopic rod, which facilitates the movement of the telescopic rod.

[0009] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model, by setting up a support rod, telescopic spring, telescopic rod, rebar hook, scale ruler, pull rope and fixing buckle, realizes the accurate transmission of the position and elevation of the underground rebar cage that cannot be measured to the ground, thereby enabling the workers to accurately determine the position and elevation of the rebar cage while standing on the ground, effectively improving the convenience of elevation measurement.

[0014] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0015] Please see Figure 1-2 This utility model provides a technical solution: a coordinate positioning and elevation reflection device for a pile foundation reinforcement cage, including a support rod 1, a telescopic spring 2 fixedly connected to the inner wall of the support rod 1, a telescopic rod 3 fixedly connected to one end of the telescopic spring 2, a reinforcement hook 4 fixedly connected to one end of the telescopic rod 3, a scale ruler 5 fixedly connected to the top of the support rod 1, a pull rope 6 movably connected inside the support rod 1, and a fixing buckle 7 fixedly connected to the top of the pull rope 6. By setting up the support rod 1, telescopic spring 2, telescopic rod 3, reinforcement hook 4, scale ruler 5, pull rope 6 and fixing buckle 7, the position and elevation of the reinforcement cage located underground and unmeasurable can be accurately transmitted to the ground, thereby enabling workers to accurately determine the position and elevation of the reinforcement cage while standing on the ground, effectively improving the convenience of elevation measurement.

[0016] Furthermore, the support rods 1 are arranged in an "I" shape when viewed from the front, and in a "Y" shape when viewed from above, which facilitates the support work.

[0017] Furthermore, the telescopic rod 3 forms a telescopic structure with the support rod 1 through the telescopic spring 2, and the telescopic rod 3 is distributed at equal angles along the longitudinal center line of the support rod 1, which facilitates the fixing work.

[0018] Furthermore, one end of the pull rope 6 is connected to the telescopic pole 3, which facilitates the movement of the telescopic pole 3.

[0019] In use, the locking buckle 7 first drives the pull rope 6 to slide, which in turn drives the telescopic rod 3 to slide. This controls the stretching of the telescopic spring 2, facilitating the telescopic rod 3 to slide and fix the rebar hook 4. This then allows the top stirrup of the pile foundation reinforcement cage to be fixed via the rebar hook 4 on the top telescopic rod 3. The top stirrup of the reinforcement cage is also the location of the pile top elevation. Next, the second stirrup of the pile foundation reinforcement cage is fixed via the rebar hook 4 on the bottom telescopic rod 3, thus completing the fixing work. This allows the scale 5 to extend beyond the ground, making it easier to determine the center of gravity of the reinforcement cage. Therefore, by detecting the position and elevation of the center point of the locking buckle 7, the positioning of the pile diameter reinforcement cage and the pile top elevation can be determined, allowing the reinforcement cage to be placed at the designed pile center and designed pile top elevation.
