[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes an external hanging cantilever scaffold, which includes a frame body 1, on which cantilever arms 101 for connecting to a building 100 are provided, and multiple construction work platforms 103 are provided on the frame body 1; protective units, corresponding to the number of work platforms 103, are provided on the periphery of the corresponding work platforms 103, and each protective unit includes a first guard arm 2 and a second guard arm 401 symmetrically provided at the end of the work platform 103; wherein, a protective net 3 is provided between the first guard arm 2 and the second guard arm 401 and between two first guard arms 2, and the protective net 3 is used to prevent falling objects; a limiting unit is provided on the frame body 1 to limit each first guard arm 2 and each second guard arm 401.

[0021] The detailed working process of this embodiment is as follows: The frame 1 is set on the building 100 through the cantilever arm 101 to provide a construction platform. After the protective unit is retracted, the first protective arm 2 and the second protective arm 401 are fixed on the frame 1 through the protective unit to facilitate installation and transportation.

[0022] By installing first guard arms 2 and second guard arms 401 around the working platform 103, and installing protective nets 3 between the first guard arms 2 and second guard arms 401 and between the two first guard arms 2, a more spacious activity space is provided for construction workers inside the scaffolding. At the same time, the protective units are set up corresponding to the working platform 103, and protective nets 3 are installed between the first guard arms 2 and second guard arms 401 and between the two first guard arms 2 in each protective unit. This can accurately protect the area around each working platform 103, effectively prevent falling objects from the working platform 103, ensure the safety of construction workers and the area below, and not affect the overall space inside the scaffolding due to the protective measures.

[0023] The frame 1 is equipped with protective netting 3 on three sides, and the side without protective netting 3 is closer to the building 100.

[0024] like Figure 2As shown, a limiting seat 4 is symmetrically arranged at both ends of the frame 1 and is located at the end of the corresponding working platform 103. One end of each second guard arm 401 is hinged to the corresponding limiting seat 4, and one end of each first guard arm 2 is hinged to the frame 1. The hinge points of each first guard arm 2 and each second guard arm 401 on the same side of the working platform 103 are on the same horizontal plane.

[0025] The detailed working process of this embodiment is as follows: the first guard arm 2 is hinged to the frame 1, the second guard arm 401 is hinged to the limiting seat 4, and the hinge points of each first guard arm 2 and each second guard arm 401 on the same side of the same working platform 103 are on the same horizontal plane. The opening angles of the first guard arm 2 and the second guard arm 401 are the same. When the first guard arm 2 and the second guard arm 401 are opened along the hinge points, the protective net 3 can be unfolded to form a protective area to prevent objects from falling from height.

[0026] like Figure 3 As shown, each first guard arm 2 is hinged with a support arm 201, and the frame 1 is fixedly provided with a number of support seats 204 corresponding to the first guard arm 2, and all of them are located on the lower side of the corresponding first guard arm 2. The end of each support arm 201 away from the hinge point is respectively engaged with the corresponding support seat 204.

[0027] The detailed working process of this embodiment is as follows: With the support arm 201, an additional support point is provided for the first guard arm 2, which greatly enhances the stability of the first guard arm 2. This means that the first guard arm 2 no longer relies solely on its hinge point with the frame 1 to maintain balance. The cooperation between the support arm 201 and the support base 204 can share some of the force, effectively reducing the deformation or shaking of the first guard arm 2 caused by the force, ensuring the stability of the overall structure of the protective unit, and ensuring that the protective net 3 can better play its role in blocking falling objects. When the first guard arm 2 is retracted and attached to the frame 1, the support arm 201 is attached to the first guard arm 2 under the action of gravity.

[0028] like Figure 3 As shown, each of the first guard arms 2 has a slot 202.

[0029] The detailed working process of this embodiment is as follows: With the setting of the slot 202, the first guard arm 2 can fit into the frame 1 in the retracted state, making the whole compact.

[0030] like Figure 3 As shown, the limiting unit includes a number of mounting seats 402 corresponding to each of the first guard arm 2 and each of the second guard arm 401 and disposed on the frame 1. Each mounting seat 402 is threadedly connected to a limiting block 403. Each of the first guard arm 2 and each of the second guard arm 401 has a limiting groove 203 at the end away from the hinge. Each mounting seat 402 is located in the corresponding limiting groove 203.

[0031] The detailed working process of this embodiment is as follows: Each first guard arm 2 and each second guard arm 401 has a limit groove 203 at the end away from the hinge. When the protective net 3 needs to be retracted, the first guard arm 2 and each second guard arm 401 rotate along the hinge point to fit against the frame 1. At this time, each mounting seat 402 is located in the corresponding limit groove 203. Then, the limit block 403 is rotated to limit and fix it.

[0032] like Figure 2 As shown, a connecting sleeve 102 is provided on the top of the frame 1.

[0033] The detailed working process of this embodiment is as follows: With the setting of the connecting sleeve 102, a stable interface can be formed, which allows multiple sets of frames 1 to overlap, thereby improving their stability. When overlapping, simply insert the bottom support of another frame 1 into the corresponding connecting sleeve 102, and then connect it to the building 100 through the cantilever arm 101. The required height can be overlapped as needed, and the installation and disassembly are convenient and quick.

[0034] like Figure 2 As shown, each work platform 103 can be detached and mounted on the frame 1.

[0035] The detailed working process of this embodiment is as follows: the work platform 103 is detachably mounted on the frame 1. During the transportation process, the work platform 103 can be removed to reduce the overall weight of the frame 1.

[0036] The implementation principle of this application embodiment is as follows: First, the frame 1 is set at the required position of the building 100 by the cantilever arm 101. Then, the first guard arm 2 and the second guard arm 401 are unfolded, and the protective net 3 is unfolded to form a protective area to ensure the safety of the construction personnel and the area below. When it is necessary to store it, the first guard arm 2 and each of the second guard arms 401 are rotated along the hinge point to make them fit with the frame 1. At this time, each mounting seat 402 is located in the corresponding limiting groove 203. Then, the limiting block 403 is rotated to limit and fix it.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
