[0023] Embodiment 1

[0024] As Figure 1 shown, this embodiment discloses a cross-frame structure, which includes a plurality of square frames 200 and a central connecting rod member 100. The square frame 200 includes a first connecting rod member 210 and a second connecting rod member 220. The central connecting rod member 100 is of I-shaped steel structure. The two side surfaces of the central connecting rod member 100 along the first direction are flat side walls, and the two side surfaces of the central connecting rod member 100 along the second direction are grooves. A plurality of square frames 200 are respectively connected to each side surface of the central connecting rod member 100. The horizontal side of the square frame 200 connected to the flat side wall of the central connecting rod member 100 along the first direction has only one first connecting rod member 210, and the horizontal side of the square frame 200 connected to the groove of the central connecting rod member 100 along the second direction is in the form of a connection between one first connecting rod member 210 and one second connecting rod member 220.

[0025] Specifically, the size and shape of the first connecting rod member 210 are exactly the same as those of the central connecting rod member 100. The square frame 200 is a semi-enclosed structure with one end open, which includes two horizontal sides and one vertical side. The vertical side of the square frame 200 is arranged in parallel and at intervals with the central connecting rod member 100. One of the two horizontal sides is respectively connected to the central connecting rod member 100 and the head end of the vertical side of the square frame 200, and the other one is respectively connected to the central connecting rod member 100 and the tail end of the vertical side of the square frame 200. That is to say, the three sides of the square frame 200 and the central connecting rod member 100 together form a closed quadrilateral structure.

[0026] In this embodiment, the first direction and the second direction are perpendicular to each other, and a total of four square frames 200 are connected to the four sides of the central connecting rod member 100.

[0027] In this embodiment, the length of the first connecting rod member 210 is longer than that of the second connecting rod member 220.

[0028] As Figure 2 shown, in the first direction, a total of two square frames 200 are fixedly connected to the planar side walls on both sides of the central connecting rod member 100, and the two square frames 200 are located on the same straight line. Among them, the horizontal sides of the two square frames 200 are composed of the horizontally arranged first connecting rod member 210.

[0029] As Figure 3 shown, in the second direction, a total of two square frames 200 are fixedly connected to the bottom of the grooves on both sides of the central connecting rod member 100, and the two square frames 200 are located on the same straight line. Among them, since the square frames 200 in the second direction need to be inserted into the grooves, in order to make up for the difference in their horizontal sides from those in the first direction, the horizontal sides of the two square frames 200 are connected to each other by the horizontally arranged first connecting rod member 210 and the second connecting rod member 220. Finally, the total length of the two square frames 200 in the first direction is the same as the total length of the two square frames 200 in the second direction.

[0030] Optionally, as another implementation manner, only one of the horizontal sides of the two square frames 200 in the second direction adopts the form of the first connecting rod member 210 and the second connecting rod member 220, and the horizontal side of the other only includes one first connecting rod member 210 (the same structure as the square frame 200 in the first direction). This structural design can reduce the use of the second connecting rod member 220. Only one second connecting rod member 220 needs to be arranged on one side of the central connecting rod member 100, saving the usage quantity of the second connecting rod member 220 and simplifying the installation steps. In this case, the length of one second connecting rod member 220 is equal to the total depth of the grooves on both sides of the central connecting rod member 100, so as to ensure that the total length of the two square frames 200 in the first direction is the same as the total length of the two square frames 200 in the second direction.

[0031] In this embodiment, mounting plates are provided at the upper and lower ends of the first connecting rod member 210 and the second connecting rod member 220. The mounting plates are flat plates with bolt holes formed thereon, so as to facilitate the fixed connection between different first connecting rod members 210 and second connecting rod members 220.

[0032] Optionally, the central connecting rod member 100, the first connecting rod member 210, and the second connecting rod member 220 are all made of Q235 steel.

[0033] The cross-frame structure in this embodiment has equal lengths on both sides, which is conducive to ensuring that each cell of the frame structure is a standard square structure. Since the horizontal and vertical spacings of the scaffolding placed on the frame structure are the same, this cross-frame structure can effectively adapt to the scaffolding and ensure the stability of the scaffolding placement.

[0034] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
