Description

Technical Field

[0001] This utility model relates to a limiting component, specifically a limiting component for lowering and connecting a pile foundation steel cage, belonging to the field of building engineering technology. Background Technology

[0002] The reinforcing cage is a crucial component of bridge pile foundation structures, and its connection quality directly affects the overall stability, load-bearing capacity, and safety and service life of the entire bridge project. The lowering and segmented connection of the reinforcing cage are critical steps in the construction of bridge pile foundations.

[0003] However, traditional rebar cage lowering and splicing operations generally face numerous challenges. Due to the lack of a stable and convenient operating platform, construction workers often have to work at height or on unstable temporary supports when connecting, welding, or binding rebar cages. This not only leads to low construction efficiency but also makes it difficult to guarantee the quality of the connection. For example, without reliable support, the positioning and connection accuracy of the rebar cage is difficult to control, and problems such as misalignment and skewness are prone to occur, which in turn affect the load-bearing performance of the pile foundation.

[0004] Furthermore, traditional construction methods pose serious safety hazards. Workers performing complex operations at heights or in confined spaces are highly susceptible to falls, tool drops, and other accidents. This is especially true for steel reinforcement cages for large-diameter, ultra-long pile foundations, which require even greater stability and safety during lowering and connection, demands that traditional methods often fail to meet.

[0005] Therefore, developing a safe and reliable limiting component for lowering and connecting the pile foundation steel cage is the key to solving the above-mentioned technical problems. Summary of the Invention

[0006] In view of the many defects and shortcomings existing in the above-mentioned background technology, this utility model has made improvements and innovations, aiming to provide a stable and easy-to-operate limiting component for lowering and connecting pile foundation steel cages, solving problems such as poor safety and difficulty in ensuring positioning and docking accuracy, thereby improving construction efficiency and installation quality.

[0007] To solve the above problems and achieve the above-mentioned invention objectives, this utility model provides a limiting component for lowering and connecting a pile foundation reinforcement cage, which is achieved by adopting the following design structure and the following technical solution:

[0008] A limiting component for lowering and connecting a pile foundation reinforcement cage, comprising:

[0009] The control panel has multiple insertion and removal holes that extend circumferentially through its side wall.

[0019] Preferably, the anti-detachment clamp is square in shape and is fixedly connected to the upper part of the inner end of the insert plate, or the anti-detachment clamp and the insert plate are processed into an integral structure.

[0020] Preferably, the operating table also has multiple weight-reducing holes circumferentially extending through its sidewalls at equal intervals.

[0021] Working principle: The working principle of this utility model is as follows: It utilizes its circular operating platform to provide a stable operating space, and uses several pluggable hanging plates (2) to temporarily fix and release the steel cage (5); when the steel cage (5) needs to be connected, the hanging plates (2) suspend the steel cage (5), and at the same time, the anti-detachment plate (3) on the hanging plate (2) prevents the steel cage (5) from accidentally falling off or sliding during the suspension process, so that the steel cage (5) remains stable during the connection process; when the connection is completed, the removal of the hanging plates (2) allows the connected steel cage (5) to continue to be lowered; when two steel cages (5) are connected, in order to ensure the rapid connection of the two steel cages (5), they are connected and fixed by the connecting sleeve (6), thus completing the connection work of the two steel cages (5), further ensuring the accuracy and safety of the overall steel cage lowering.

[0022] The connecting sleeve (6) used above is a straight thread sleeve, which facilitates the quick and accurate connection and fixing of the vertical steel bars of the upper and lower steel cages (5) to ensure the connection quality.

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] As per the instruction manual Figures 1 to 10 As shown, a limiting component for lowering and connecting a pile foundation reinforcement cage includes:

[0052] The control panel 1 has multiple insertion and removal holes 11 circumferentially extending through its side wall.

[0053] The insertion plate 2 is inserted into each insertion hole 11 to suspend the steel cage 5.

[0054] The inner end of the insert plate 2 is provided with an anti-detachment clip plate 3.

[0055] Furthermore, the outer end of the insert plate 2 is also provided with a handle 4 for conveniently pulling the insert plate 2.

[0056] Specifically, the handle 4 is U-shaped, L-shaped, T-shaped, spherical, ring-shaped, or columnar, and anti-slip texture is provided on the handle 4.

[0057] Preferably, the handle 4 is a circular cylindrical body, and the middle part of the circular cylindrical body is horizontally fixed to the middle part of the outer end of the insert plate 2.

[0058] Furthermore, the operating table 1 is generally circular in shape.

[0059] Furthermore, the operating table 1 is composed of two semi-circular components connected together to form a ring-shaped operating platform.

[0060] Furthermore, the insertion and removal holes 11 are equidistantly circumferentially opened through the side wall of the operating table 1.

[0061] Specifically, four insertion holes 11 are equidistantly provided on the side wall of the control panel 1.

[0062] Furthermore, the insertion and removal holes 11 are opened circumferentially through the side wall of the operating table 1 at unequal intervals.

[0063] Furthermore, the insertion plate 2 has an overall rectangular plate structure, and the lower part of the side inside the operating table 1 is designed with a chamfer to facilitate insertion or removal of the insertion hole 11.

[0064] Specifically, the lower inner end of the insert plate 2 is cut to form an inclined edge structure, so that it is easier to insert or pull out the insertion hole 11, and at the same time, it is convenient to drive the anti-detachment plate 3 on the insert plate 2 to be inserted into the insertion hole 11.

[0065] Furthermore, the anti-detachment plate 3 is generally square in shape, and the anti-detachment plate 3 is fixedly connected to the upper part of the inner end of the insert plate 2, or the anti-detachment plate 3 and the insert plate 2 are processed into an integral structure.

[0066] Furthermore, the operating table 1 is also provided with a plurality of weight-reducing holes 12 that are equidistantly circumferentially extending through its sidewall.

[0067] In this utility model, the multiple weight-reducing holes 12 that are equidistantly and circumferentially opened on the operating table 1 can be of different shapes such as circular, elliptical, square, hexagonal or groove, in order to achieve the purpose of weight reduction and structural optimization.

[0068] In this utility model, the weight-reducing hole 12 is not limited to reducing the weight of the operating table 1, thereby effectively reducing the overall weight of the operating table and improving its ease of handling and installation; secondly, when used in conjunction with other fixed equipment such as support frames and connectors, the weight-reducing hole 12 can enhance the structural stability and seismic performance of the operating table 1, ensuring its stability and safety during use; in addition, the shape and arrangement of the weight-reducing hole 12 can also effectively disperse the external pressure, prevent excessive local stress from causing structural damage, thereby extending the service life of the operating table 1.

[0069] The working principle of this utility model is as follows: It utilizes its circular operating platform to provide a stable operating space, and uses several pluggable hanging plates 2 to temporarily fix and release the reinforcing cage 5. When the reinforcing cage 5 needs to be connected, the hanging plates 2 suspend the reinforcing cage 5. At the same time, the anti-detachment clamps 3 on the hanging plates 2 prevent the reinforcing cage 5 from accidentally falling off or sliding during the suspension process, ensuring the stability of the reinforcing cage 5 during connection. After the connection is completed, pulling out the hanging plates 2 allows the connected reinforcing cage 5 to continue to be lowered. When connecting two reinforcing cages 5, in order to ensure a quick connection, they are connected and fixed using connecting sleeves 6, thus completing the connection of the two reinforcing cages 5 and further ensuring the accuracy and safety of the overall reinforcing cage lowering.

[0070] The connecting sleeve 6 used above is a straight thread sleeve, which facilitates the quick and accurate connection and fixing of the vertical reinforcing bars of the upper and lower reinforcing cages 5, ensuring the connection quality.

[0071] In summary, a more specific embodiment of this utility model is as follows:

[0072] Before using the aforementioned design structure, a limiting component for lowering and connecting the pile foundation steel cage needs to be manufactured and installed as a backup.

[0073] When using,

[0074] Step 1: The construction personnel first hoist the operating platform 1 to the top of the pile hole and securely install it at the pile hole opening or on the pre-set support structure to ensure the level and stability of the operating platform 1.

[0075] Step 2: The operator uses the lifting equipment 7 to lower the first section of the steel cage 5 into the pile hole, so that its upper end is slightly higher than the operating platform of the operating table 1.

[0076] Step 3: The construction workers insert the four hanging plates 2 into the insertion holes 11 respectively, push the hanging plates 2 inward, and insert the anti-detachment clamping plate 3 into the inner side of the ring hoop of the steel cage 5 until the four hanging plates 2 are in place. Then, the operators can slowly release the first section of the steel cage 5 downward until the ring hoop of the steel cage 5 is suspended on the four hanging plates 2.

[0077] Step 4: The construction workers tighten the connecting sleeves 6 on each of the vertical steel bars at the top of the first section of the steel cage 5.

[0078] Step 5: The operator uses the lifting equipment 7 to hoist the second section of the steel cage 5 to the top of the operating platform 1. With the cooperation of the construction personnel, each vertical steel bar at the bottom of the second section of the steel cage 5 is precisely sleeved into the connecting sleeve 6 at the top of the first section of the steel cage 5. The first section of the steel cage 5 and the second section of the steel cage 5 are then securely connected. Subsequently, the construction personnel remove the four insert plates 2 outward through the insertion holes 11 from the first section of the steel cage 5. Then, the installation, connection and lowering of the other steel cages 5 are carried out in sequence.

[0079] Step 6: Repeat steps 2 to 5 until all steel cages 5 are connected and lowered to the designed depth of the pile hole.

[0080] During the above installation process, the connecting sleeve 6 is tightened onto the two adjacent vertical steel bars by means of a tool thread. At the same time, in order to make the connection between the two adjacent steel cages 5 more stable, after the connecting sleeve 6 is tightened and fixed, the connecting sleeve 6 can be welded to the corresponding steel cage 5 so that the adjacent steel cages 5 are connected as a whole.

[0081] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
