The mounting assembly is used to connect the entire hanging ladder to the steel column. It includes a connecting plate A, a connecting plate B, a mounting frame, and a hook. The connecting plate A is fixed to the side of the steel column. The connecting plate B is bolted to the connecting plate A after being attached to it. The mounting frame is fixedly connected to the connecting plate B. The upper end of the hook is hooked onto the mounting frame, and the lower end is connected to the angle steel ladder beam of the uppermost standard section of the hanging ladder.

[0007] This utility model discloses a steel structure assembled vertical climbing ladder installation structure. Furthermore, the standard section of the hanging ladder is provided with a lateral support component, which is fixedly installed on the angle steel ladder beam and supported on the outer side of the steel column.

[0008] This utility model discloses a steel structure assembled vertical climbing ladder installation structure. Furthermore, the lateral support component includes U-shaped parts, which are arranged in pairs on two angle steel ladder beams, and the two ends of the U-shaped parts are fixedly connected to the angle steel ladder beams.

[0009] This utility model discloses a steel structure assembled vertical climbing ladder installation structure. Furthermore, the hanging frame is an isosceles triangle structure, and the two sides of the hanging frame are bent along the side of the connecting plate B at the intersection to form a connecting rod, which is fixedly connected to the connecting plate B.

[0010] This utility model discloses a steel structure assembled vertical climbing ladder installation structure. Furthermore, the lower part of the two waist sides of the hanging frame is bent away from the steel column, so that the waist side and bottom side of the hanging frame are separated from the same vertical plane.

[0011] This utility model discloses a steel structure assembled vertical climbing ladder installation structure. Further, the step is connected to the front end face of the angle steel ladder beam, and the outer sleeve and inner sleeve are both connected to the side end face of the angle steel ladder beam. The distance between the outer sleeve and inner sleeve and the front end face of the angle steel ladder beam is the width of the step.

[0012] This utility model discloses a steel structure assembled vertical climbing ladder installation structure, further wherein the inner sleeve rod is provided with adjustment holes spaced apart to cooperate with bolts.

[0013] Compared with the prior art, this utility model has the following advantages: 1. High efficiency and speed: Modular design and hook-type installation significantly shorten installation and dismantling time, improving construction efficiency; 2. High versatility: By setting standard sections and expansion joints for the hanging ladder, the overall length of the hanging ladder is adjustable, adapting to different steel column installations, greatly improving turnover rate and reducing overall cost; 3. Protection of the base material: No welding is required on the construction site throughout the entire process, avoiding heat-related impacts and damage to the steel column base material; 4. By selecting angle steel as the ladder beam and connecting the rungs and ladder expansion joints to the two sides of the angle steel respectively, a rung width is reserved on the front face of the ladder expansion joint and the standard ladder section for the installation of the supplementary rung. The supplementary rung and the rung are located in the same vertical plane, ensuring the consistency of the ladder steps and avoiding safety risks to workers caused by changes in the step position after the ladder is extended or retracted.

Width; The dimensions of the rear supplementary step bar 3.3 are consistent with those of the step bar 2.2. The rear supplementary step bar 3.3 can be detachably installed on the front end face of a pair of outer sleeves 3.1 and / or the front end face of a pair of inner sleeves 3.2. The detachable installation method is bolt fixing. The rear supplementary step bar 3.3 and the step bar 2.2 are located in the same vertical plane, so that the positions of the step bar 2.2 and the step bar are consistent after the ladder is extended or retracted, which facilitates the climbing of construction personnel and ensures safety. When extension or retraction is required, only the inner sleeves 3.2 can be extended or retracted. In this case, the rear supplementary step bar 3.3 is installed on the front end face of the inner sleeves 3.2 by bolts. Alternatively, the position of the outer sleeves 3.1 can be moved downward to cooperate with the inner sleeves 3.2 to achieve bidirectional extension or retraction. In this case, the rear supplementary step bar 3.3 is installed on the front end face of the outer sleeves 3.1, which has a larger adjustment range and stronger adaptability.

[0020] The mounting assembly 4 is used to connect the entire hanging ladder to the steel column 1. It includes a connecting plate A4.1, a connecting plate B4.2, a mounting frame 4.3, and a hook 4.4. The connecting plate A4.1 is fixed to the side of the steel column 1. The connecting plate B4.2 is bolted to the connecting plate A4.1 after being fitted together. The mounting frame 4.3 is fixedly connected to the connecting plate B4.2. The upper end of the hook 4.4 is hooked onto the mounting frame 4.3, and the lower end is welded and fixed to the angle steel ladder beam 2.1 of the uppermost standard section 2 of the hanging ladder.

[0021] The standard section 2 of the hanging ladder is provided with a lateral support component 5. The lateral support component 5 is fixedly installed on the angle steel ladder beam 2.1 and supported on the outer side of the steel column 1. The lateral support component 5 includes U-shaped parts, which are arranged in pairs on the two angle steel ladder beams 2.1. The two ends of the U-shaped parts are fixedly connected to the angle steel ladder beams 2.1.

[0022] The hanging frame 4.3 is an isosceles triangle structure. The two sides of the hanging frame 4.3 are bent along the side of the connecting plate B4.2 at the intersection to form the connecting rod 4.5. The connecting rod 4.5 is close to both sides of the connecting plate B4.2 and is fixedly connected to the connecting plate B4.2.

[0023] Furthermore, the lower part of the two waist sides of the hanging frame 4.3 is bent away from the steel column 1, so that the waist side and bottom side of the hanging frame 4.3 are separated from the same vertical plane, reducing the influence of the waist side and making it easier to install and remove the hook 4.4.

[0024] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
