[0001] The present application relates to the field of building construction technology, and in particular to a channel device based on an external protective scaffolding platform for assembled building projects. Background Art

[0002] With the continuous development of the construction industry and the increasingly diverse market demands, prefabricated technology, with its advantages of high efficiency, environmental protection, and energy conservation, has gradually become a key development direction in the engineering construction field. At the same time, to speed up the construction of prefabricated buildings, prefabricated staircases are often used as staircases. However, the installation of prefabricated scissor ladders in prefabricated buildings is not synchronized with the construction of the floor structure. This leads to safety hazards such as the edge of the stairwell opening, the lack of an operating platform for the stairwell formwork on the same floor, and the lack of up and down access in the stairwell, which leads to safety hazards such as workers having to climb up and down.

[0017] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0018] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0019] The embodiment of this specification provides a passage device based on an external protective scaffolding platform for assembled building engineering, including an external protective scaffolding platform A, which includes two upper and lower adjacent walkway boards, the two walkway boards including a first walkway board 1 and a second walkway board 2. Figure 1 As shown, the walkway board has a through hole 3 that runs through the top and bottom surfaces. The through hole 3 is welded and reinforced with 3.0mm thick 50×50mm square steel around it. A cover plate 4 is provided on the through hole. A ladder 5 is provided between adjacent walkway boards. The top of the ladder 5 is detachably connected to the through hole 3 above, and the bottom of the ladder 5 is provided on the walkway board below. It should be noted that both the first walkway board and the second walkway board have through holes. If it is necessary to climb from the second walkway board to the first walkway board, the cover plate of the first walkway board is opened and the cover plate of the second walkway board is closed. The user enters the first walkway board from the ladder through the through hole.

[0020] In one possible implementation, see Figure 2 As shown, the through hole 3 is a rectangular structure with a surrounding reinforced square steel. A protrusion 31 is provided on the inner bottom of the reinforced square steel. The cover plate 4 is pivotally connected to the reinforced square steel at one end, and the other end can be placed on the protrusion. This allows the top of the cover plate to be flush with the top of the walkway plate, allowing the cover plate to be laid flat when the ladder is not in use without affecting the normal use of the walkway plate. The protrusion 1 is provided with at least one first bolt hole 32. A connecting plate 51 is provided on one side of the top of the ladder 5. This connecting plate has a second bolt hole 52 that matches the first bolt hole.

[0021] Further preferably, protective plates 6 are provided on the facades on both sides of the external protective scaffolding platform, and the protective plates are provided on both sides of the ladder. The protective plates include but are not limited to the use of climbing frame mesh, such as Figure 4 shown.

[0022] When using, please refer to Figure 3 As shown, place the connecting plate at the top of the ladder onto the protrusion, align the axes of the first and second bolt holes, and then insert the bolts to secure. The bottom of the ladder is placed on the walkway board below, and the ladder is placed at an angle. There is no need to install a separate scissor ladder, which greatly improves the portability and safety of construction. The ladder can also be installed and used directly using the external protective scaffolding platform channel, reducing safety hazards for workers going up and down the work surface and improving construction safety. It can also be used in a revolving manner, reducing construction investment costs. Once set up, it can be used continuously during the construction process, greatly improving construction efficiency.

[0023] Further preferably, the bottom of the ladder is detachably connected to the walkway plate below, and is connected by plug bolts 8. The stability during use and the portability during assembly and disassembly can be improved.

[0024] Furthermore, a first perforated plate 71 is welded to the columns on both sides of the external protective scaffolding platform. A second perforated plate 72 is mounted on the protective plate to match the first perforated plate. The first and second perforated plates are connected by a latch. This facilitates assembly and disassembly. The protective plates enhance safety when using the ladder.

[0025] It should also be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, commodity, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or includes elements inherent to such process, method, commodity, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, commodity, or apparatus that includes the element.

[0026] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
