The aim is to effectively reduce the safety protection cost and floor passage cost through standardized and lightweight design, while improving construction efficiency and safety. Background Technique
[0002] With the rapid development of prefabricated building technology, the wide application of prefabricated components has greatly improved the speed and quality of building construction. However, before the installation of prefabricated stairs, how construction workers can safely and efficiently pass between floors has become a major challenge. Generally, steel hanging ladders are used for floor construction passage. This method requires protection on both the vertical and horizontal surfaces of the stairwell, and there are safety problems for personnel passage and construction workers cannot carry items with larger sizes; another method is to set up a pedestrian passage on the external scaffold, but there are problems of high construction costs and inability to carry larger items. Moreover, neither of these two methods can provide a working platform for stairwell formwork installation.
[0003] The patent with the application number CN202310397421.1 discloses a safety protection cage ladder, which relates to the technical field of safety construction, including a ladder body and a cage frame. The cage frame is fixed on the ladder body. A longitudinal beam is arranged in the center of the cage frame, an inverted T-shaped slide rail is arranged inside the longitudinal beam, and a following mechanism is arranged in the slide rail. The following mechanism includes a positioning block, a runner, a locking mechanism and an elastic fitting mechanism. The positioning block is in an I-shaped shape, and the positioning block is installed in the inverted T-shaped slide rail. The top plate of the positioning block is located outside the inverted T-shaped slide rail. The elastic fitting mechanism is arranged at the bottom end of the positioning block. The runners are arranged on both sides of the bottom end of the positioning block. The runners match the width of the inverted T-shaped slide rail, and the runners are rotatably connected with the positioning block. The locking mechanism is arranged in the positioning block and is rotatably connected with the positioning block. Guide rings are arranged at both outer ends of the positioning block.

[0039] Please refer to Figures 1 to 3 .
[0040] The prefabricated building standardized cage ladder of the present invention includes a skeleton assembly, two sets of step assemblies 2000, three sets of movable assemblies, and a railing assembly.
[0041] The skeleton assembly includes several skeleton assembly pipes 1100 and two cage ladder support beams 1200. The skeleton assembly pipes 1100 are detachably connected and fixed to each other by bolts to form a cage ladder skeleton 1000. The inside of the cage ladder skeleton 1000 is divided into upper and lower cage ladder spaces. The two cage ladder support beams 1200 are respectively detachably connected to the lower side of the cage ladder skeleton 1000 by bolts. The cage ladder skeleton 1000 contacts the ground through the two cage ladder support beams 1200.
[0042] The skeleton assembly pipes 1100 use high-strength steel pipes as the main material. The specifications of the steel pipes are selected according to the load-bearing requirements of the stairwell and safety standards. Through precise calculation and design, the steel pipes form a stable frame structure. The cross-sectional shape, size and connection method of the cage ladder skeleton 1000 are optimized to ensure the stability and load-bearing capacity of the overall structure. High-strength bolts are used to connect between the skeleton assembly pipes 1100, and appropriate specifications and materials need to be selected for the bolt connection to ensure reliable and firm connection.
[0043] Two groups of tread assemblies 2000 are respectively arranged in the two cage ladder spaces. The tread assembly 2000 includes two support pipes 2200 and several tread plates 2100. The two support pipes 2200 are arranged obliquely and parallelly. The upper and lower ends of the support pipes 2200 are respectively detachably connected to the skeleton assembly pipes 1100 of the skeleton assembly by buckles. The tread plates 2100 are processed from the stairs of color steel plate houses and the surfaces are anti-slip treated. The near-side side walls of the tread plates 2100 extend downward with baffle parts 2110. The tread plates 2100 and the baffle parts 2110 are respectively connected to the support pipes 2200 through connectors 2300. The connectors 2300 are of sleeve structure. The connectors 2300 are welded and fixed to the tread plates 2100 or the baffles. The connectors 2300 are sleeved on the support pipes 2200. Several tread plates 2100 are arranged in sequence on the two support pipes 2200. The tread plates 2100 are in a horizontal state and the baffle parts 2110 are in a vertical state. The distal end of one of the adjacent two tread plates 2100 abuts against the baffle part 2110 of the other tread plate 2100. The tread plates 2100 are arranged in a stepped shape, and the height and width of each tread plate 2100 meet the safety standards.
[0044] The lower end position of the lower tread assembly 2000 is close to the ground. The upper end position of the lower tread assembly 2000 is close to the lower end position of the upper tread assembly 2000. The upper end position of the upper tread assembly 2000 is close to the top of the cage ladder skeleton 1000.
[0045] The movable assembly includes a movable platform 3100 and two side suspension ropes 3200. One end of one side of the movable platform 3100 is hinged to the cage ladder skeleton 1000, and the other end of the movable platform 3100 is fixed to the cage ladder skeleton 1000 through the two side suspension ropes 3200.
[0046] The material of the movable platform 3100 is steel plate or alloy plate, etc. The movable platform 3100 needs to have a certain load-bearing capacity and durability. The movable platform 3100 is set at the stair turning platform and is connected to the cage ladder skeleton 1000 by hinges. The movable platform 3100 can rotate or slide around a fixed point to realize the opening and closing functions.
[0047] The movable platform 3100 is connected to the cage ladder skeleton 1000 by hinges. Ensure that the movable platform 3100 is stable and smooth during the opening and closing process. At the same time, the movable platform 3100 also needs to be provided with a limiting device to prevent damage or safety accidents caused by excessive opening or closing of the movable platform 3100.
[0048] The railing assembly includes a number of railing frames 4100, and the number of railing frames 4100 are detachably connected to the top surface of the cage ladder skeleton 1000 by buckles.
[0049] For the installation of this prefabricated building standardized cage ladder, the size of the cage ladder needs to be determined according to the stairwell design drawings and prefabricated before installation. During installation, use a tower crane or crane to lift the standardized cage ladder as a whole to the designated position in the stairwell, and ensure that the cage ladder is stable and does not shake through fine adjustment. The design of this prefabricated building standardized cage ladder needs to pass safety calculations.
[0050] During use, construction workers can safely and conveniently pass between floors through the cage ladder. The movable flap opens when needed to allow personnel to pass through and then automatically resets and closes.
[0051] Embodiment Two
[0052] Please refer to Figure 4 as shown.
[0053] The difference between this embodiment and Embodiment One is only that: in this embodiment, the connecting piece structure of the tread assembly is different from that in Embodiment One. The specific structure of the connecting piece is:
[0054] The connecting piece of the tread assembly includes a buckle body 2310 and a U-shaped buckle 2320. The buckle body 2310 is provided with an assembly groove 2311 for accommodating the U-shaped buckle 2320. The assembly groove 2311 runs through both sides of the buckle body 2310. The U-shaped buckle 2320 is provided with a card slot that fits the outer contour of the support tube 2200. The U-shaped buckle 2320 on the side away from the opening of the card slot is hinged to one side wall of the assembly groove 2311 of the buckle body 2310. The other side wall of the assembly groove 2311 of the buckle body 2310 is provided with a limiting notch 2312. The two ends of the U-shaped buckle 2320 are respectively a first end 2321 and a second end 2322. The distance from the first end 2321 to the hinged position of the buckle body 2310 is less than the distance from the second end 2322 to the hinged position of the buckle body 2310. The second end 2322 of the U-shaped buckle 2320 can cooperate with the limiting notch 2312.
[0055] The U-shaped buckle 2320 is hinged to the buckle body 2310 through a pin shaft 2330. A torsion spring (not shown in the figure) is sleeved on the pin shaft 2330, and the torsion spring causes the U-shaped buckle 2320 to tend to flip outward to the outside of the assembly groove 2311 of the buckle body 2310.
[0056] The connecting piece in this embodiment can enable the tread board to be quickly connected, assembled and disassembled with the support pipe 2200.
[0057] The above are only two implementation manners of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several modifications and improvements can be made, and these should also be regarded as belonging to the protection scope of the present utility model.
