[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the embodiments of the present disclosure are further described in detail in combination with the embodiments and drawings. The schematic implementation methods of the embodiments of the present disclosure and their descriptions are only used to explain the embodiments of the present disclosure and are not intended to limit the embodiments of the present disclosure.

[0024] First, refer to Figure 1 and describe a construction ladder for building construction of the present application. As Figure 1 shown, a construction ladder for building construction of the present application includes a base 1, at least a pair of support columns 2, a plurality of treads 3, a locking device 4, and a surface attachment enhancement mechanism 5. The support columns 2 are installed on the top of the base 1, and the number thereof can be selected according to actual usage requirements. However, in order to ensure that the construction ladder has necessary stability and load-bearing capacity, at least two should be provided to form a stable triangular structure; a plurality of treads 3 are fixedly connected between at least a pair of support columns 2 for workers to climb and operate. The design of the tread 3 takes into account the load-bearing performance and the safety of the operators. While ensuring a certain width, anti-slip patterns and other surface treatments are adopted to increase the friction force and prevent slipping.

[0025] The locking device 4 is designed to be movably disposed at a certain height between any two adjacent treads 3 among at least a pair of support columns 2. Its specific structure may include forms such as pins, buckles, or other mechanical devices, so that the height of the construction ladder can be quickly adjusted according to the height of the construction site environment, thereby effectively meeting the dimensional requirements under different operation needs. At the same time, this structure can also be folded by changing the position, which is convenient for space utilization during handling and storage.

[0026] The surface attachment enhancement mechanism 5 is disposed at one end of the base 1, aiming to fix the construction ladder to the wall or the ground to enhance its stability performance, especially suitable for relatively smooth or sloping places to prevent tipping or slipping. Generally, this component includes, but is not limited to, more than one fixture (such as jaws) or suction cup devices, and makes it closely adsorb to the surface of the building or the horizontal plane of the placement area through simple physical extrusion to achieve the fixing effect, thereby greatly improving the working safety level of the equipment.

[0027] Technically, the base 1 of the construction ladder can be made of materials with high strength and moderate weight (such as metal or composite materials), and the clamping or adsorption type enhancement mechanism 5 equipped at its bottom should have sufficient elastic deformation ability and friction characteristics, and can still maintain the original fixing effect without loosening easily under the condition of a large external acting force.

[0028] In one embodiment, as Figure 1 and Figure 3As shown, a construction ladder for building construction in the present application realizes more reliable stability and adaptability through the design of its unique surface attachment enhancement mechanism 5, especially having significant advantages when facing uneven surfaces such as bumps and depressions. The specific structure of the surface attachment enhancement mechanism 5 is at least one claw, and in practical applications, an appropriate number of claws can be selected according to actual situations to achieve the optimal effect. These claws are equipped with an internal spring 6 device. The design of the spring 6 enables each claw to elastically contract or expand under the external pressure when encountering different terrains and surface conditions. Such a design allows the claws to automatically adjust to a suitable position and tightly grip small gaps, crevices, and other uneven areas on the building or ground surface. This series of designs greatly improves the embedding ability of the claws and the attachment stability.

[0029] For example, by selecting an appropriate spring 6 stroke and hardness, it can be ensured that the claws can effectively function without failure under various complex conditions. At the same time, it is necessary to ensure that the material of the claws themselves has a certain strength and wear resistance so as not to deform or break after multiple telescopic movements, thereby ensuring the safe use performance of the surface attachment enhancement mechanism 5 during the entire building process.

[0030] In one embodiment, as Figure 2 shown, a construction ladder for building construction in the present application, the surface attachment enhancement mechanism 5 of the construction ladder is specifically composed of several suction cups. An edge ring made of a soft material is designed around the above-mentioned suction cups, preferably rubber. Such a structure can form a tight physical contact between the suction cups and the supported building surface. This feature significantly increases the adhesion force and adsorption strength of the suction cups to the building surface, effectively avoiding the safety problems easily caused by insufficient friction in traditional construction ladders, especially being more crucial under adverse conditions such as wet or dusty conditions. The soft edge ring 7 can not only enhance airtightness but also ensure the stable state of the construction ladder on a hard or uneven wall surface and can adapt to a certain range of wall surface flatness differences. In addition, the rubber material can also provide good elastic deformation characteristics, which is beneficial to the safe and simple disassembly after construction while maintaining a strong attachment ability.

[0031] Specifically, for example, the optimal effect can be achieved by precisely controlling the number, size, and arrangement of the suction cups on the construction ladder. In addition, in order to make the rubber soft edge ring 7 play the best role, it is also necessary to ensure its certain thickness and appropriate soft hardness during production and design. In actual production, the most suitable formulation ratio and processing method can be determined through multiple tests. In some embodiments, the overall stability and durability of the product can be further improved by adding materials for anti-aging and anti-ultraviolet radiation to better meet the outdoor use conditions.

[0032] In one embodiment, a construction ladder for building construction according to the present application, as Figure 4 shown, is provided with a rotary button 8 at the bottom end of the base 1 for fixing the central position of the suction cup. When this rotary button 8 is rotated, the air pressure condition inside the suction cup is changed through the internal mechanism connected to the suction cup to form a negative pressure environment, enhancing the adsorption and fitting degree of the suction cup to the contact surface, especially the wall surface, and effectively avoiding the possible ladder shaking or instability during the construction process. By adding such a functional component that can manually operate and adjust the air pressure and designing it to be easily adjustable by the user without leaving the ladder, not only the safety and convenience during the building construction process are improved, but also the practicality of the product is enhanced.

[0033] For example, at the technical level, this feature can be achieved by installing a valve system inside the base 1 that is linked to the rotary button 8 and controls the vacuum degree of the suction cup. When the operator rotates the button 8, it starts a small motor by means of a shaft connected to the valve or uses the principle of mechanical lever to open and close the exhaust valve located in the suction cup; as the internal gas is gradually discharged to form a low-pressure area, the suction cup can be more tightly adsorbed on the wall surface, ensuring a stable supporting effect while facilitating quick deployment and disassembly, and adapting to the flexible application requirements under different working conditions.

[0034] In one embodiment, a construction ladder for building construction according to the present application is provided with anti-slip pads 9 around the bottom of the base 1. These anti-slip pads 9 are made of high-strength and wear-resistant materials, and their main purpose is to increase the stability of the ladder when placed on a slippery ground. When it is necessary to operate this ladder in a wet or water-rich place, the high-strength and wear-resistant anti-slip pads 9 can strengthen the friction between the base 1 and the ground by increasing the grounding area and raising the friction coefficient of the contact area, thereby effectively preventing the ladder from sliding during use and improving the safety of work. This design not only improves the safety of workers when operating the ladder, but also enhances the applicable range and service life of the ladder under different environmental conditions.

[0035] To achieve this function, the anti-slip pads 9 are usually embedded or fixedly bonded around the bottom edge of the base 1. The selection of wear-resistant materials should consider that they can resist external wear for a long time while maintaining sufficient hardness and grip. For example, silicone, polyurethane or rubber are common selection materials, which can not only ensure durability but also have good friction, and can effectively prevent the bottom of the ladder from slipping due to moisture. In addition, the surface of the anti-slip pads 9 can be textured or micro-nails can be installed according to the specific use environment to further improve the grip performance.

[0036] In one embodiment, as Figure 1As shown, in a construction ladder for building construction of the present application, a number of pairs of support columns 2 are provided in its structure, and a limiting baffle 10 is installed between each pair of support columns 2. The limiting baffle 10 is arranged on the side of the support column 2 close to the construction surface (such as a wall). Its design purpose is to ensure that when the construction ladder is set perpendicular to the wall surface (for example, in the case of high-altitude operations, when moving vertically up and down by clamping the base 1 in a gap), the contact area between the construction ladder and the wall is increased, thereby effectively restricting the possible lateral displacement. This can not only significantly improve the overall stability and load-bearing capacity of the construction ladder, but also, to a certain extent, improve the resistance of the structure to lateral forces, and avoid imbalance and safety hazards caused by lateral deflection.

[0037] For example, to achieve this function, the following method can be adopted: weld or install with fasteners on the corresponding surfaces of a pair of support columns 2 a baffle made of metal or high-strength composite material. The baffle is designed to be a flat surface, so as to increase the contact area with the wall.

[0038] In one embodiment, as Figure 1 shown, the surface attachment enhancement mechanism 5 of a construction ladder for building construction of the present application is provided with a detachable and replaceable gripping tip 11, which can quickly replace different types of gripping components when facing different types of working surfaces. The establishment of this mechanism enables the entire ladder to better adapt to the changing construction site, especially when dealing with situations such as muddy foundations or concrete structures, it can stand more firmly and stably on various surface materials. This mechanism effectively enhances the flexibility and adaptability of the ladder in construction applications, and improves the usage efficiency and safety of the ladder.

[0039] To achieve the above effects, a set of connecting devices can be set at the lower part of the main body of the construction ladder, and various shapes and sizes of gripping tips 11 are equipped to achieve this interchangeability, so as to ensure that the best adapted type can be selected according to the texture of the specific working surface. For example, a threaded locking or quick clamping type fixing scheme is designed to ensure its convenient disassembly and assembly while having good fixing strength. These gripping tips 11 are usually made of durable and corrosion-resistant materials so that they will not be easily damaged even when exposed to harsh environments for a long time. In this way, both convenient replacement and the requirements for high-intensity construction operations are achieved.

[0040] In one embodiment, for a construction ladder used in building construction, in order to provide a more stable working platform and ensure safety and reliability in various environments, threaded holes are pre-embedded in the base 1 so that users can use corresponding expansion screws or other similar fasteners to fix the entire construction ladder to the ground or work surface according to specific operation requirements. This design can not only effectively avoid problems such as the ladder tipping over and shifting caused by water accumulation, uneven ground surface, or strong wind weather at the work site, but also adapt to different construction site conditions, enhancing its application universality and convenience. By cooperating with devices such as suction cups provided on the base 1 to form a multiple safety protection system, it provides comprehensive safety protection during the process of the operator climbing, greatly improving the safety and reliability of use.

[0041] For example, to achieve the above features, high-strength steel threaded sleeves can be pre-embedded in the appropriate positions inside the material of the base 1 by one-time molding using a precision mold. These threaded holes match the specifications of expansion screws or other auxiliary fixing devices. When it is necessary to fix the equipment, the user only needs to select an appropriate type of fixing component according to the actual situation of the operation location and screw it into the pre-embedded threaded holes to a sufficient tightening degree, thereby ensuring the stability and reliability of the overall structure. Such a design is both simple and practical, effectively meeting the safety requirements during the construction process.

[0042] During the actual operation process, when this device is in use, the worker first places the base 1 at the ideal position on the construction site and unfolds the support columns 2 to initially form a stable basic structure. Multiple pedals 3 are firmly installed between two corresponding support columns 2 as the part for climbing up and down. Then, the worker will adjust the position of the locking device 4 according to the actual space size and operation requirements - by moving it to shorten or extend the distance between each section, which can not only optimize space utilization but also enhance the overall stability of the ladder itself. After the locking device is set, it is the turn of the surface adhesion enhancement mechanism 5 to play its role. At this time, the worker will operate at least one claw or suction cup connected to the base 1 to make it closely adhere to the wall surface or other surface contact planes. These claws or suction cups will firmly grasp the target surface under pressure, ensuring that the entire construction ladder can be stable when there are lateral or other external forces acting. In this way, after completing all the adjustment settings, this construction ladder can effectively adapt to various complex working conditions and maintain extremely high safety, not only reducing the risk of tipping over but also increasing the worker's operation confidence. After the construction is completed, it only needs to simply reverse the steps to easily disassemble and fold it, which is convenient for subsequent carrying or storage.

[0043] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
