Description
Technical Field
[0001] This utility model relates to the field of scaffolding, specifically to a scaffolding upright bottom anti-settlement reinforcement device. Background Technology
[0002] Scaffolding is widely used in the construction industry. Its core function is to provide workers with a stable high-altitude working platform and height support, making it a key auxiliary facility to ensure the smooth progress of high-altitude construction operations. However, the existing scaffolding structural design still has technical defects in terms of insufficient structural stability when facing complex construction environments, and its applicability under special foundation conditions urgently needs to be improved.
[0003] Specifically, in construction scenarios, scaffolding is often erected on ground with low bearing capacity, such as backfilled soil or soft ground. In this case, the overall load of the scaffolding is concentrated at the base of the four corner uprights, resulting in significant pressure in the area where the uprights contact the ground. Because the foundation soil cannot withstand this concentrated load, localized settlement is highly likely. As the work continues or the load increases, the settlement at the base of the uprights gradually expands, leading to deviations in the verticality of the scaffolding uprights. Ultimately, this causes the entire scaffolding structure to tilt and become unstable, resulting in its collapse. This can cause accidents such as workers falling from heights and damage to construction equipment, resulting in significant casualties and economic losses for the construction company.
[0004] Currently, the industry often uses temporary measures such as laying steel plates and crushed stone layers to address this problem. However, these methods can only disperse local pressure to a certain extent and cannot fundamentally solve the problem of stable connection between the bottom of the uprights and the foundation. Furthermore, they have drawbacks such as cumbersome installation, poor adaptability, and limited reinforcement effect. Therefore, developing a reinforcement device that can effectively resist foundation settlement and ensure structural stability by specifically optimizing the bottom structure of the four corner uprights of scaffolding has become an urgent technical problem to be solved in the construction industry.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-5As shown, this utility model is a scaffolding upright bottom anti-settlement reinforcement device, including a support component 1. The upper outer surface of the scaffolding upright 3 is threadedly connected to the support component 1, and the lower outer surface of the scaffolding upright 3 is uniformly rotatably installed with a reinforcement support pad 2. The support component 1 includes a threaded sleeve 19, a conical cover 17 welded to the bottom of the threaded sleeve 19, a handle 18 symmetrically welded to the upper outer surface of the threaded sleeve 19, a limiting arc-shaped sliding groove 15 evenly opened on the upper surface of the lower edge of the conical cover 17, a first connecting groove 14 evenly opened on the outer periphery of the bottom of the conical cover 17, an annular hole 11 penetrating through the inside of the first connecting groove 14, an annular pin 12 slidably inserted into the inside of the annular hole 11, a tension spring 13 fixedly connected to one end of the annular pin 12, a swivel ring 16 fixedly connected to the upper outer surface of the annular pin 12, an anti-slip texture 21 provided on the bottom surface of the reinforced support pad 2, a connecting protruding ring 22 welded to the middle outer surface of the reinforced support pad 2, and a connecting shaft hole 23 opened on the upper outer surface of the reinforced support pad 2. The middle outer surface of the scaffold upright 3 is provided with an external thread 31, the bottom end of the scaffold upright 3 is rotatably installed with a limit shaft 32, the lower outer surface of the scaffold upright 3 is provided with a roller 33, and the lower outer surface of the scaffold upright 3, located at the edge of the roller 33, is evenly provided with a second connecting groove 34.
[0020] The threaded sleeve 19 is threaded to the outer surface of the scaffold upright 3 via an external thread 31, allowing the support component 1 to rise and fall on the upper surface of the scaffold upright 3, thereby pressing and positioning the reinforcing support pad 2. The bottom of the conical cover 17 is arc-shaped, which facilitates the bottom of the conical cover 17 to press against the upper surface of the reinforcing support pad 2, reducing friction. The upper part of the annular pin 12 passes through the limiting arc-shaped slide groove 15 and is connected to the rotating ring 16, which can control the synchronous sliding of the four sets of annular pins 12 by pulling the rotating ring 16, thus reinforcing the support. The pad 2 is aligned and inserted into the first connecting groove 14 through the connecting protrusion 22 in the middle. One end of the annular pin 12 passes through the center of the connecting protrusion 22 inside the first connecting groove 14, so that the annular pin 12 can lock the position of the reinforcing support pad 2 after it is flipped up, so as to prevent the reinforcing support pad 2 from drooping down and obstructing the movement of the scaffold. The reinforcing support pad 2 is rotatably connected to the limiting shaft 32 through the connecting shaft hole 23, which can ensure that the reinforcing support pad 2 flips up and down. The bottom of the conical cover 17 is in contact with the upper outer surface of the reinforcing support pad 2.
[0021] The working principle of this utility model is as follows: During the construction process, scaffolding needs to be adapted to different foundation conditions. When erecting on ground with low bearing capacity, such as backfill soil or soft ground, it is necessary to use the reinforcing support pad 2 to prevent the bottom of the upright from settling. The specific operation steps are as follows: First, pull the rotating ring 16 outward. Through the fixed connection between the rotating ring 16 and the annular pin 12, the four sets of annular pins 12 will be driven to slide horizontally along the annular hole 11 until the end of the annular pin 12 is completely separated from the center hole of the connecting protrusion ring 22 in the middle of the reinforcing support pad 2, and the locking of the reinforcing support pad 2 is released. At this time, under its own weight, the reinforcing support pad 2 will naturally deflect downward with the connecting shaft hole 23 connected to the limiting shaft 32 as the rotating axis until the anti-slip texture 21 on its bottom surface is completely in contact with the ground. Subsequently, the operator holds the symmetrical handles 18 on the support component 1 and rotates the threaded sleeve 19 clockwise. Since the threaded sleeve 19 is engaged with the external thread 31 on the outer surface of the scaffold upright 3, the threaded sleeve 19 will drive the bottom conical cover 17 to move downward along the upright axis during rotation. As the conical cover 17 descends, its bottom arc-shaped end face will gradually squeeze the upper outer surface of the four sets of unfolded reinforced support pads 2. Through the squeezing action of the conical structure, a rigid limit is formed on the unfolding angle of the reinforced support pads 2, effectively restricting them from flipping upward when bearing the vertical load of the scaffold. After the bottom of the uprights at the four corners of the scaffolding has been reinforced, the four sets of extended reinforcement support pads 2 significantly increase the contact area between the bottom of the uprights and the ground, evenly distributing the concentrated load of the scaffolding to a larger area of the foundation. This significantly reduces the pressure of the bottom of the uprights on the ground, fundamentally preventing the uprights from tilting due to foundation settlement, ensuring the stability of the high-altitude work platform, and providing reliable protection for the personal safety of the workers. When the scaffolding is finished and needs to be moved or stored, the operator holds the handle 18 in the opposite direction and rotates the threaded sleeve 19 counterclockwise, causing the conical cover 17 to move upward along the upright axis until its bottom is completely separated from the reinforcing support pad 2, releasing the compression limit. Then, the operator must first pull the rotating ring 16 outward to compress the tension spring 13 with the annular pin 12 and slide it along the annular hole 11, leaving space for the storage of the reinforcing support pad 2. Then, flip the reinforcing support pad 2 upward so that it retracts upward with the connecting shaft hole 23 as the rotating axis until the connecting protrusion 22 in the middle of the reinforcing support pad 2 is precisely aligned and inserted with the first connecting groove 14 at the bottom of the conical cover 17. At this time, release the rotating ring 16, and the annular pin 12, under the restoring force of the tension spring 13, automatically passes through the center hole of the connecting protrusion 22 and inserts into the annular hole 11, completing the storage and locking of the reinforcing support pad 2, preventing it from drooping and swaying during the movement of the scaffolding, and not affecting the normal transfer of the scaffolding. In summary, through the coordinated operation of support component 1 and reinforced support pad 2, the scaffolding can be quickly reinforced and stored on low-bearing-capacity ground, effectively solving the problem of easy settlement and tilting of traditional scaffolding, and greatly improving the safety and adaptability of scaffolding in complex working conditions.
[0022] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
