Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a simple device for preventing the collapse of the steel cage of a dry-drilled cast-in-place pile. Background Technology

[0002] Dry-forming bored piles are widely used in construction projects due to their advantages such as strong adaptability, no vibration, and no soil displacement. In this construction process, accurately and stably placing the steel cage into the pile hole at the designed elevation is the core link to ensure the quality of pile formation.

[0003] Currently, the common construction method is to use hoisting followed by suspension positioning and auxiliary fixing methods. This mainly involves positioning the pipe by placing a crossbeam on top of the casing at the borehole or on the ground, or by welding positioning ribs. However, the following problems exist in the subsequent installation of the guide pipe and pouring of concrete:

[0004] First, the impact force of concrete can easily cause the suspended steel cage to swing, shift, or even tilt or float up, resulting in serious quality defects such as insufficient protective layer thickness of the steel cage and missing steel bars in the pile body, which affect the bearing capacity and durability of the pile foundation.

[0005] Secondly, using welded positioning bars not only involves cumbersome operation and inconsistent stability, but also may damage the main reinforcement bars.

[0006] Based on this, this utility model proposes a simple device to prevent the steel cage of a dry-drilled cast-in-place pile from tipping over. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model proposes a simple device to prevent the steel cage of dry-drilled cast-in-place piles from tilting, which can effectively prevent the steel cage from tilting or deviating during concrete pouring.

[0008] The technical solution to achieve the purpose of this utility model is: a simple device to prevent the overturning of the reinforcing cage of a dry-drilled cast-in-place pile, comprising a reinforcing cage, wherein the outer peripheral wall of the reinforcing cage is provided with reinforcing devices at equal intervals, and the reinforcing devices include a first reinforcing ring and a second reinforcing ring.

[0009] In some embodiments, multiple connecting steel bars are welded and fixed together between the first steel bar ring and the second steel bar ring, and a reinforcing iron ring is welded and fixed to the outer peripheral wall of the second steel bar ring.

[0010] Compared with existing technologies, the significant advantages of this invention are:

[0011] Firstly, this utility model utilizes existing steel bar rings and reinforcing iron rings to form a reinforcement device, which can provide temporary support for the steel bar cage, making it easier to prevent the steel bar cage from tilting or shifting during the pouring process, thereby affecting the quality of the concrete pouring.

[0012] Secondly, this utility model can be fabricated on-site using existing materials according to the diameter of the reinforcing cage, which is convenient and practical. On-site processing is simple and the cost is low. It can be widely applied to dry-operation concrete cast-in-place piles to prevent the reinforcing cage from tilting or being misaligned, greatly improving the practicality of this device.

[0013] This method addresses the common practice in existing construction where suspended positioning and auxiliary fixing methods after hoisting are used. However, during subsequent processes such as installing guide pipes and pouring concrete, the impact force of the concrete material can easily cause the suspended steel cage to swing, shift, or even tilt or float, resulting in serious quality defects such as insufficient protective layer thickness and missing pile reinforcement, which affect the bearing capacity and durability of the pile foundation. Furthermore, using welded positioning bars not only involves cumbersome operation and inconsistent stability but also risks damaging the main reinforcement bars. Attached Figure Description

[0020] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] This utility model provides a simple device to prevent the overturning of the reinforcing cage of a dry-drilled cast-in-place pile. The technical solution of this utility model is as follows:

[0022] like Figures 1-3 As shown, a simple device for preventing the overturning of the reinforcing cage of a dry-drilled cast-in-place pile includes a reinforcing cage 1. Reinforcing devices 6 are equidistantly arranged on the outer peripheral wall of the reinforcing cage 1. The reinforcing devices 6 include a first reinforcing ring 2 and a second reinforcing ring 3. The reinforcing devices 6 can reinforce the reinforcing cage 1 and, together with the inner peripheral wall of the grouting hole, can stabilize the reinforcing cage 1, preventing the reinforcing cage 1 from overturning or shifting during the concrete pouring process, thereby affecting the quality of the concrete pouring.

[0023] Furthermore, multiple connecting steel bars 5 are welded and fixed together between the first steel bar ring 2 and the second steel bar ring 3. A reinforcing iron ring 4 is welded and fixed to the outer peripheral wall of the second steel bar ring 3. The connecting steel bars 5 are used to improve the structural strength of the reinforcement device 6. Together with the reinforcing iron ring 4, the stability of the reinforcement device 6 on the steel cage 1 can be further improved.

[0024] The specific working method is as follows: Based on the diameter of the steel cage 1 at the construction site, select appropriate steel ring 1 2 and steel ring 2 3 and weld them together with connecting steel bars 5. Then, weld the reinforcing iron ring 4 to the outer circumferential wall of steel ring 2 3. At this point, the reinforcing device 6 is assembled. Install the reinforcing device 6 into the gap between the cast-in-place pile and the steel cage 1. After installation, concrete is poured. This can effectively prevent the steel cage 1 from tilting or shifting during the pouring process, thereby affecting the quality of the concrete pouring.

[0025] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
