Description

Technical Field

[0001] This invention relates to a construction ladder, and more particularly to a safe and stable steel structure construction ladder. Background Technology

[0002] In the construction of high-rise buildings, ladders and other auxiliary tools are often used for ascending and descending. Since these ladders need to support construction workers, their stability and safety requirements are high. However, traditional ladders are mostly simple in structure, consisting of a simple steel frame and a ladder. In use, the ladder needs to be hung on the steel frame and then secured with wire. Securing the ladder to the column with wire can stabilize the ladder simply hung on the steel frame, preventing it from swaying due to uneven stress caused by manual climbing. However, securing a suspended ladder with wire at a high altitude is a relatively cumbersome and time-consuming process, greatly consuming manpower and time, and easily introducing various safety hazards. Summary of the Invention

[0019] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0020] Reference Figure 1 A safe and stable steel structure construction ladder 1 includes a column 3, a ladder 1, and a connector 2. The connector 2 is fixed to the column 3. The end of the ladder 1 is equipped with a hanging structure, and the ladder 1 is hung on the connector 2 via the hanging structure. Since the ladder 1 is generally installed at the top of the main structure at a high altitude, installing the ladder at a high position is troublesome. However, the connection between the ladder 1 and the column 3 via the connector 2 allows for a simple hanging connection, making high-altitude operations more convenient. The hanging structure is equipped with a locking structure 4, and the connector 2 is also equipped with a limiting structure 5. The locking structure 4 and the limiting structure 5 are used to limit and lock the ladder 1 on the connector 2, respectively. When the ladder 1 is connected to the main structure via hanging, the connection point is suspended only by gravity. Under uneven forces, it is prone to swaying or even detaching from the hanging position, posing a safety hazard to construction workers. The locking structure 4 locks the hanging structure to the connector 2, ensuring that the hanging structure and the connector 2 will not separate, thus guaranteeing the safety of the hanging ladder. The limiting structure 5 limits the hook 12 when the hanging structure is attached, preventing the hook 12 from swaying left and right under force, which would cause the hanging ladder to shake and create a danger for construction workers climbing on the hanging ladder.

[0021] To further enhance the safety of construction workers using the ladder 1, a binding strap 6 is installed between the column 3 and the ladder 1 to connect the workers. The binding strap 6 is secured to the ladder 1 by wrapping around the column 3. Since the ladder is attached to the connector 2 at the top and has no fixed connection at the bottom, it is prone to swaying during use. Therefore, a binding strap 6 is installed near the bottom of the ladder in the middle. After wrapping around the column 3, the binding strap 6 secures the ladder 1 near the bottom to the column 3, adding a fixing point to the ladder 1 and further increasing its stability.

[0022] The connector 2 includes a fixing block 21, a connecting block 22, and a hanging bracket 23. The fixing block 21 is fixedly mounted on the column 3. The connecting block 22 is used to connect with the fixing block 21. The hanging bracket 23 is used to suspend the ladder 1. The limiting structure 5 is mounted on the hanging bracket 23. The fixing block 21 is provided with bolt holes. The connecting block 22 consists of two pieces, which are connected to the fixing block 21 on both sides by bolts. The hanging bracket 23 is triangularly arranged, with two sides of the triangular hanging bracket 23 fixedly connected to the two connecting blocks 22. The base of the hanging bracket 23 is horizontal. The triangular hanging bracket 23 has a simple structure and better stability. When the column 3 is being built, the fixing block 21 is already fixedly mounted on the top side of the column 3. Before installing the ladder 1, the two connecting blocks 22 are aligned with the fixing block 21 on both sides and connected by bolts. Both the fixing block 21 and the connecting block 22 are provided with bolt holes, and there are multiple bolt holes.

[0023] Reference Figure 2 The triangular hanging bracket 23 is horizontally positioned at the bottom, with both sides providing traction to the bottom, resembling a clothes hanger. The ladder 1 includes a ladder body 11 and hooks 12, which are used to hang on the hanging bracket 23, and a locking structure 4 is provided on the hooks 12. The limiting structure 5 includes limiting members 51 and limiting grooves 52. The limiting grooves 52 are located at the bottom of the hanging bracket 23, and the limiting members 51 limit the ladder 1 by sliding within the limiting grooves 52. Multiple limiting members 51 are provided within the limiting grooves 52, with a portion of each limiting member 51 sliding within the limiting grooves 52 and a portion located outside the limiting grooves 52. The total width of the multiple limiting members 51 and hooks 12 is equal to the width of the limiting grooves 52. Preferably, the limiting member 51 is a steel ball. When hook 12 is attached to hanger 23, the bottom of hook 12 contacts the horizontal surface of hanger 23. A limiting groove 52 is provided at the top of the horizontal surface of hanger 23. The limiting member 51 in the limiting groove 52 first contacts hook 12. Since hook 12 is a cylindrical hook made of steel bars, when hook 12 presses on limiting member 51, the arc-shaped surface at the bottom of hook 12 and the arc-shaped surface of limiting member 51 will form a misaligned pressure. After being subjected to the misaligned pressure, limiting member 51 slides to both sides of hook 12. In this way, hook 12 can directly contact the surface of hanger 23, while the limiting members 51 squeezed to both sides form a horizontal movement limit on hook 12. This limiting structure 5 is not only easy to manufacture, but also realizes automatic limiting of hook 12 during the attachment process, increasing the stability and safety of hook 12 while retaining the convenience of the attachment process. In addition, the size and quantity of this limiting component 51 can be set according to the size of the hook 12. For different models of hook 12, it is only necessary to replace the hanger 23 with a different model of limiting structure 5 to use it, which has a wide range of applications.

[0024] Since hook 12 is only attached to bracket 23, slight shaking will not significantly affect the connection between them. However, with larger movements, hook 12 can easily detach from bracket 23, directly causing ladder 1 to separate from column 3 and increasing the risk of injury to on-site workers. Therefore, a locking structure 4 is provided on hook 12. The locking structure 4 includes a hook tongue 41 and an elastic element 42. One end of hook tongue 41 is rotatably connected to the bottom of hook 12, and the other end of hook tongue 41 is engaged with the end of hook 12. The elastic element 42 is used to elastically separate hook 12 and hook tongue 41. A pivot is provided at the end of hook tongue 41, which passes through the bottom of hook 12 and is rotatably connected to the bottom of hook 12. A baffle 43 is also provided on the side of the pivot of hook tongue 41 to prevent hook tongue 41 from popping out and engaging with the end of hook 12. The hook tongue 41 and hook 12 form a safety hook 12 configuration. When the ladder 1 is hooked, the hook opening of hook 12 is blocked by the hook tongue 41. However, since the hook tongue 41 and hook 12 are elastically connected, when the hook tongue 41 is pressed, it rotates inward into hook 12, opening the hook opening and allowing hook 12 to be hooked onto the hanger 23. At this point, the hook tongue 41 loses pressure, and the spring between it and hook 12 returns, springing the hook tongue 41 back to the hook 12 engagement position. The hook tongue 41 only deforms elastically when pressure is applied externally. When the hanger 23 inside hook 12 applies pressure to the hook tongue 41, the baffle 43 at the bottom of the hook tongue 41 blocks the bottom of hook 12, preventing the hook tongue 41 from rotating in the opposite direction. This creates a reverse locking process for hook 12 during suspension, ensuring the safety of hook 12 during use. Multiple hooks 12 are provided on the ladder body 11, and each hook 12 is provided with a locking structure 4. In order to keep the ladder body 11 balanced during suspension, one hook 12 is generally provided on each of the two sides of the top of the ladder body 11.
