[0045] Compared with existing external scaffolding, the advantages of this invention are as follows:

[0046] 1) This invention modularizes the frame plate components of the external scaffolding. The frame plate units are connected to each other to form an integral structure, which together bear and provide a safe working platform and external protective barrier. This reduces the number of components to be installed and dismantled on site, makes installation and dismantling convenient, and ensures structural safety and reliability.

[0047] 2) The socket in this invention adopts a structure that expands vertically, horizontally, and front-back, with a closed top, giving the socket and plug a higher connection rigidity. Compared with the existing external scaffolding structure that is narrower horizontally, vertically, and front-back, with an open top, the socket design of this invention can effectively improve the rotational rigidity of the connection node in the vertical plane.

[0048] 3) This invention uses irregularly shaped tubes to overlap the scaffold boards with the outer frame panels and the inner frame panels, complementing the connection between sockets and plugs. The irregularly shaped tube cross-sections of the frame between the scaffold boards and the outer and inner frame panels interlock, reducing the possibility of loosening between the scaffold boards and the outer and inner frame panels, further ensuring the integrity of the external scaffolding and improving its stability.

[0049] 4) The connector structure of the present invention is simple, and the inner and outer frame plates only need to be connected to the connector by insertion pipes, while the scaffold boards only need to be connected to the connector by insertion. This connection method can more tightly fix the connector and each frame plate of the external scaffold, avoiding problems such as loose connectors that exist in traditional connection methods.

[0050] 5) The outer frame plate unit of the present invention utilizes the skin effect of the metal mesh on the structure, so that the metal mesh and the metal frame share the force and form a closed safety space immediately after installation, thereby reducing the safety hazards that may occur during the use of external scaffolding.

[0051] 6) The inner frame of this invention is designed according to the characteristics of scaffolding use, with handrails and frame forming a unit together, which not only improves the overall performance of the external scaffolding, but also effectively avoids safety hazards such as loose or missing handrails.

[0052] 7) Compared with traditional steel pipe scaffolding, the frame plate scaffolding of this invention has a simple composition, is easy to disassemble and install, can improve construction efficiency, and has good market application prospects. Attached Figure Description

[0081] like Figure 1As shown, a frame-plate type ground-supported external scaffolding includes scaffold boards 1, outer frame boards 2, inner frame boards 3, connectors 4, adjustable bases 5, and wall ties 6. The outer frame boards 2 and inner frame boards 3 are arranged vertically and parallel to each other, and horizontal scaffold boards are provided at the bottom or top between the outer frame boards 2 and inner frame boards 3.

[0082] In the entire scaffolding structure, a single scaffolding unit is formed by scaffold boards 1, outer frame boards 2, and inner frame boards 3; Figure 1 As can be seen, multiple frame units are connected vertically along the connector 4 to form a multi-layer frame, and then connected horizontally to form a passageway; at the turning points of the entire frame, they are connected to each other through corner frame units; the bottom of the entire frame is fixed to the ground through an adjustable base 5; the connector 4 is provided with a wall tie 6 that is fixed to the building wall, and the frame is fixed to the construction building through the wall tie 6.

[0083] exist Figure 1 In the scaffolding, the scaffolding board 1 includes two types: standard section scaffolding board 11 and corner scaffolding board 12.

[0090] like Figure 2 As shown, the frame of the standard section scaffold board 11 includes two horizontally parallel first connecting pipes 101 and two vertically parallel first square tubes 102. The two first connecting pipes 101 and the two first square tubes 102 are connected and fixed at the four corners by four connecting diagonal tubes 105, forming a complete frame. The first connecting pipes 101 are irregularly shaped tubes with symmetrical vertical alignment. Interlocking second square tubes 104 are fixed inside this frame; a footboard net 107 is arranged on the first connecting pipes 101, first square tubes 102, second square tubes 104, and connecting diagonal tubes 105.
