Description

Technical Field

[0001] This utility model relates to the field of safety ladders, and in particular to a building safety ladder that prevents tilting. Background Technology

[0002] In the construction industry, construction safety ladders are one of the core pieces of equipment ensuring the safety of construction workers working at heights and moving between floors. They typically consist of a metal frame, ladder structure, and basic protective components, and are widely used in various construction scenarios such as high-rise building construction, exterior wall decoration, and equipment installation. The installation of construction safety ladders must be carried out according to the actual working conditions of the construction site. Generally, the ground in the construction area is first leveled and cleaned, then the main frame of the safety ladder is assembled in sections. Subsequently, the bottom is initially fixed to the ground using anchor bolts or counterweights. In some scenarios, the safety ladder also needs to be laterally connected to the main building structure to complete the overall installation process and provide a stable vertical passage for construction workers.

[0003] However, in actual use, construction safety ladders are prone to tilting. On the one hand, construction sites are often unpaved soil or gravel surfaces, which are easily affected by construction vehicles and material accumulation over a long period of time, leading to localized settlement, potholes, and deformation. This results in uneven stress on the bottom support points of the safety ladder, causing overall tilting. On the other hand, construction work is mostly done outdoors. If extreme weather such as strong winds or heavy rain occurs, strong winds can exert lateral thrust on the safety ladder, while heavy rain can further soften the foundation and exacerbate ground settlement. Under these combined effects, the center of gravity of the safety ladder will shift significantly, further increasing the risk of tilting or even overturning, posing a serious threat to the lives of construction workers. Utility Model Content

[0004] The main purpose of this utility model is to provide a building safety ladder that prevents tilting, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A tilt-resistant safety ladder for construction includes a main frame. A reinforced adjustable support assembly is installed on each of the four corner columns of the main frame. Each reinforced adjustable support assembly consists of a connecting component and a rotating support member. Several sets of connecting components are longitudinally and evenly fixedly installed on the rotating support member. Each connecting component consists of an installation sleeve, an installation ring, and a first connecting plate. The rotating support member consists of a support column, a second connecting plate, and a mounting base plate. Several second connecting plates are longitudinally and evenly fixedly installed on the outer wall of the support column. The mounting base plate is fixedly installed at the lower end of the support column.

[0006] Preferably, a protective mesh panel is fixedly installed on the main frame, and a stair assembly is provided inside the main frame and on the inner side of the protective mesh panel.

[0007] Preferably, the outer wall of the mounting sleeve on the connecting assembly is provided with an annular mounting groove, the mounting sleeve is sleeved on the columns at the four corners of the main frame, and the mounting sleeve is fixedly connected to the columns at the four corners of the main frame by bolts.

[0008] Preferably, the mounting collar on the connecting assembly is rotatably mounted in the annular mounting groove.

[0009] Preferably, both the first connecting plate and the second connecting plate are provided with a plurality of mounting through holes, and the first connecting plate and the second connecting plate are fixedly connected by bolts, and the lower end of the mounting base plate is flush with the lower end of the main frame.

[0010] Compared with the prior art, the present invention has the following beneficial effects: By installing reinforced adjustable support components consisting of connecting components and rotating supports on the columns at the four corners of the main frame, and by pre-embedding anchor bolts in the ground around the safety ladder using concrete pouring technology at appropriate locations based on the actual working conditions of the construction site, the reinforced adjustable support components are then fixedly connected to the pre-embedded anchor bolts. This method adds an extra connection point between the safety ladder and the ground on top of the original fixed structure of the safety ladder, effectively enhancing the stability of the connection between the safety ladder and the ground, preventing the center of gravity of the safety ladder from shifting, and significantly reducing the risk of the safety ladder tilting or even tipping over, thus providing a reliable guarantee for the safety of construction personnel passing through heights. The rotating supports can be rotated and adjusted on the connecting components, and can also be adjusted outwards or inwards relative to the connecting components, thereby adapting to different site conditions and flexibly adjusting the angle and position of the supports, enhancing the practicality of the reinforced adjustable support components.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] Please see Figure 1 - Figure 4 As shown, a tilt-resistant safety ladder for construction includes a main frame 1. A reinforced adjustable support assembly 2 is installed on each of the four corner columns of the main frame 1. Each reinforced adjustable support assembly 2 consists of connecting components 5 and rotating support members 6. Several sets of connecting components 5 are longitudinally and evenly fixedly installed on the rotating support members 6. Each connecting component 5 consists of an installation sleeve 7, an installation collar 8, and a first connecting plate 9. The rotating support member 6 consists of a support column 10, a second connecting plate 11, and a mounting base plate 12. Several second connecting plates 11 are longitudinally and evenly fixedly installed on the outer wall of the support column 10. The mounting base plate 12 is fixedly installed at the lower end of the support column 10. By installing the reinforced adjustable support assembly 2, composed of connecting components 5 and rotating support members 6, on the four corner columns of the main frame 1, the safety ladder achieves its purpose. Based on the actual working conditions of the construction site, anchor bolts can be pre-embedded in the ground around the safety ladder using concrete pouring technology at appropriate locations. The reinforced adjustable support component 2 can then be fixedly connected to the pre-embedded anchor bolts. This method can add additional connection points between the safety ladder and the ground on the basis of the original fixed structure of the safety ladder, effectively enhancing the connection stability between the safety ladder and the ground, preventing the center of gravity of the safety ladder from shifting, and significantly reducing the risk of the safety ladder tilting or even tipping over, providing a reliable guarantee for the safety of construction personnel passing through heights. The rotating support component 6 can be rotated and adjusted on the connecting component 5. At the same time, the rotating support component 6 can be adjusted outward or inward relative to the connecting component 5, thereby adapting to different site conditions and flexibly adjusting the angle and position of the support, improving the practicality of the reinforced adjustable support component 2.

[0015] Specifically, a protective mesh plate 3 is fixedly installed on the main frame 1. A stair assembly 4 is installed inside the main frame 1 and on the inner side of the protective mesh plate 3. An annular mounting groove 13 is provided on the outer wall of the mounting sleeve 7 on the connecting assembly 5. The mounting sleeve 7 is fitted onto the columns at the four corners of the main frame 1 and is fixedly connected to the columns at the four corners of the main frame 1 by bolts. The mounting ring 8 on the connecting assembly 5 is rotatably installed in the annular mounting groove 13. Several mounting through holes 14 are provided on both the first connecting plate 9 and the second connecting plate 11. Plate 9 and the second connecting plate 11 are fixedly connected by bolts. The lower end of the mounting base plate 12 is flush with the lower end of the main frame 1. In the specific installation of this anti-tilting building safety ladder, the ground in the construction area is first leveled and cleaned. Then, the main frame 1 is assembled in sections. After assembly, the main frame 1 is hoisted to the designated construction position. Then, anchor bolts or counterweights are used to initially fix the bottom of the main frame 1 to the ground. In some construction scenarios, it is also necessary to laterally tie the main frame 1 to the main building structure to complete the main frame 1. The existing method is used for fixing; then, anchor bolts are pre-embedded in the ground around the safety ladder using concrete pouring. After the anchor bolts are fully secured, the angle of the rotating support 6 is adjusted according to the actual layout of the anchor bolts: the rotating support 6, together with the first connecting plate 9 and the mounting collar 8, is rotated horizontally on the mounting sleeve 7 to adjust the position of the rotating support 6; then, the inner and outer positions of the rotating support 6 relative to the connecting assembly 5 are adjusted: first, the connecting bolts used to fix the first connecting plate 9 and the second connecting plate 11 are removed to release their fixed state; then, the rotating support 6 is moved outward or inward relative to the connecting assembly 5. When the position of the rotating support 6 is suitable and its bottom mounting plate 12 can accurately align with the pre-embedded anchor bolts, the bolts are then inserted into the mounting through holes 14 on the first connecting plate 9 and the second connecting plate 11 to complete their fixation; finally, the mounting plate 12 at the bottom of the rotating support 6 is fixedly connected to the pre-embedded anchor bolts, thus completing the installation of the reinforced adjustable support assembly 2 and achieving overall anti-tilting reinforcement of the safety ladder.

[0016] It should be noted that the mounting through holes 14 are arranged in a uniform array on the first connecting plate 9 and the second connecting plate 11, with a high density. This ensures that the rotating support 6 has multiple fixed points to choose from when adjusting its position relative to the connecting assembly 5, thereby improving adjustment accuracy and connection stability. The height of the support column 10 is the same as the height of the safety ladder. The specific number of connecting assemblies 5 and the second connecting plate 11 needs to be flexibly set according to the actual height of the safety ladder. That is, the higher the height of the safety ladder, the more connecting assemblies 5 and the second connecting plate 11 there will be, and the lower the height of the safety ladder, the fewer connecting assemblies 5 and the second connecting plate 11 there will be. This ensures that the reinforced adjustable support assembly 2 can provide uniform and stable support for the safety ladder.
