Description

Technical Field

[0001] This utility model relates to the field of pile foundation cage hoisting technology, and in particular to an anti-deviation guide frame for pile foundation cage hoisting and positioning. Background Technology

[0002] In infrastructure construction fields such as building engineering and bridge engineering, pile foundation construction is a core process to ensure the stability of the foundation of buildings or structures. The hoisting and positioning accuracy of the pile foundation cage (reinforcing cage) directly determines the verticality, bearing capacity, and overall project quality of the pile foundation. As the load-bearing skeleton of the pile foundation, the installation position of the pile foundation cage must be precisely aligned with the design axis of the pile foundation; otherwise, it will lead to uneven stress on the pile foundation, reduced bearing capacity, and even structural safety hazards.

[0003] Existing construction sites often have uneven ground or slopes. Traditional guide frames are mostly designed with fixed lengths, which cannot flexibly adjust the support height according to the flatness of the ground. This makes it difficult to keep the guide frame horizontal after installation. As a result, the pile cage is easily affected by the tilt of the guide frame, causing lateral displacement or tilting. It is impossible to accurately align with the pile hole position, requiring repeated adjustments, which seriously affects the construction efficiency. Therefore, an anti-displacement guide frame for pile cage hoisting and positioning is proposed. Utility Model Content

A tapered plate 11 is fixedly installed on the top of the guide plate 10. An installation structure for limiting the guide plate 10 is provided on the outside of the rectangular frame 1. When hoisting the pile foundation cage, the rectangular frame 1 is installed in a suitable position by the support rod 3. According to the flatness of the ground, the sliding sleeve 5 on the outside of the adjusting rod 4 is rotated. The sliding sleeve 5 drives the adjusting rod 4 to rotate, thereby adjusting the support rod 3 and the adjusting rod 4, and supporting and adjusting the rectangular frame 1 to keep the rectangular frame 1 horizontal. The guide plate 10 and the tapered plate 11 are installed inside the rectangular frame 1 through the installation structure. The pile foundation cage is guided into the guide plate 10 through the tapered plate 11, so that the guide plate 10 guides it and prevents it from deviating.

[0026] Preferably, the top of the support plate 8 is provided with a plurality of limiting holes evenly distributed. The insertion protrusion 9 is inserted into the limiting hole and the adjusting rod 4 is stopped from rotating by inserting the insertion protrusion 9 into the limiting hole at the top of the support plate 8.

[0027] Preferably, the limiting part includes multiple limiting plates 6, which are fixedly installed on the inner wall of the sliding sleeve 5 and slidably installed on the outer inner wall of the adjusting rod 4, thereby preventing the sliding sleeve 5 on the outer side of the adjusting rod 4 from rotating.

[0028] Preferably, a limiting groove is provided on the outer side of the adjusting rod 4, and the limiting plate 6 is slidably installed inside the limiting groove.

[0029] Preferably, the installation structure includes multiple connecting seats 12, which are fixedly installed on the outside of the guide plate 10. Multiple threaded rods 13 are slidably arranged on the outside of the rectangular frame 1, with one end of the threaded rod 13 inserted into the inside of the connecting seat 12 and the other end of the threaded rod 13 fixedly provided with a second gripping plate 14. A baffle 15 is threadedly connected to the outside of the threaded rod 13. In use, according to the requirements, a suitable guide plate 10 is selected and installed inside the rectangular frame 1. The threaded rod 13 is slidably passed through the rectangular frame 1, and one end of the threaded rod 13 is inserted into the inside of the connecting seat 12. Then, the position of the baffle 15 is rotated and adjusted so that it fits against the inner wall of the rectangular frame 1, thereby fixing the guide plate 10.

[0030] Preferably, the baffle 15 has a threaded hole inside, and the size of the threaded rod 13 is adapted to the threaded hole. The guide plate 10 can be disassembled and assembled through the baffle 15 and the threaded rod 13.

[0032] The following is the usage process of the anti-deviation guide frame for pile foundation cage hoisting and positioning provided by this utility model:

[0033] When hoisting the pile foundation cage, the rectangular frame 1 is installed in a suitable position using the support rod 3. Depending on the flatness of the ground, the sliding sleeve 5 is slid to a comfortable position. The sliding sleeve 5 is rotated by the first gripping plate 7, which drives the adjusting rod 4 to rotate, thereby adjusting the support rod 3 and the adjusting rod 4. The support rod 3 is fixedly connected to the connecting plate 2 on the outside of the rectangular frame 1, thereby supporting and adjusting the rectangular frame 1 to keep it level. A suitable guide plate 10 is selected and installed inside the rectangular frame 1. The threaded rod 13 is slid through the rectangular frame 1, and one end of the threaded rod 13 is inserted into the connecting seat 12. Then, the position of the adjusting baffle 15 is rotated to fit against the inner wall of the rectangular frame 1, thereby fixing the guide plate 10. The pile foundation cage is then guided into the guide plate 10 through the conical plate 11, allowing the guide plate 10 to guide it and prevent deviation.
