In the conventional ground overhead system, only the bearing layer 2 is placed on the movable part of the supporting leg 1, and in order to improve the integrity of the ground overhead system, the bearing layer 2 is formed by splicing a plurality of bearing plates 21 through connecting pieces 3, wherein the bearing plates 21 adopt a hollow structure, and vertical reinforcing supporting plates are arranged in the hollow cavity, so that the weight is reduced while the bearing effect is ensured. The connecting member 3 includes an adjusting portion 31 connected to the movable portion, and a connecting portion 32 connected to both of the adjacent two bearing plates 21. Under the structure, the movable part of one supporting leg 1 is adjusted, so that the two bearing plates 21 can be driven to move and adjust; the two bearing plates 21 are respectively connected with the other connecting pieces 3, so that the other connecting pieces 3, the supporting feet 1 connected with the other connecting pieces and the bearing plates 21 are driven to be adjusted, and the like, so that the adjustment of all the supporting feet 1 and the bearing plates 21 in the whole ground overhead system is completed.

Wherein, under the condition that the supporting leg 1 adopts the screw nut structure, the adjusting part 31 is provided with a through hole, and the through hole passes through the screw and then is lapped on the nut, so that the nut limits the height of the adjusting part 31, thereby limiting the height of the connecting piece 3, thereby limiting the height of the bearing plate 21. In order to further fix the adjusting portion 31, the adjusting portion 31 further includes a fastening nut screwed to the screw, and the adjusting portion 31 is disposed between the nut and the fastening nut and abuts against the nut and the fastening nut, respectively.

The connecting portion 32 may be various, for example, the connecting portion 32 includes flat plates respectively disposed on two sides of the adjusting portion 31, and the flat plates may be connected to any one or more of the bottom, side, and top surfaces of the bearing plate 21. As shown in fig. 3, the connecting portion 32 includes a receiving plate 321 that abuts against a surface of the bearing plate 21 near the ground, and the bearing plate 21 is supported by the receiving plate 321. Preferably, the receiving plate 321 and the adjusting portion 31 are not on the same plane, the receiving plate 321 and the adjusting portion 31 are connected through the first connecting plate, and in this bending manner, the problem that the receiving plate 321 and the adjusting portion 31 are easily broken due to the gravity of the bearing plate 21 when they are on the same plane is avoided. In addition, in order to further enhance the connection strength between the connection portion 32 and the bearing plate 21, the bearing plate 21 is provided with a clamping groove 212, and the connection portion 32 further includes an insertion plate 322 that can be inserted into the clamping groove 212.

Meanwhile, the insertion plate 322 and the adjusting part 31 are not on the same plane, similar to the receiving plate 321, and the insertion plate 322 and the adjusting part 31 are connected through a second connecting plate, so that a height difference is formed between the top surface of the bearing plate 21 and the adjusting part 31, and a space for accommodating the fastening nut is reserved.

When the receiving plate 321 and the insertion plate 322 are both flat plates, the bearing plate 21 may be inserted between the receiving plate 321 and the insertion plate 322 from the side during installation. In this configuration, the mounting of the bearing plate 21 is facilitated, but similarly, the bearing plate 21 is easily reversed and slid out from the connecting portion 32, and therefore, in this embodiment, the locking groove 212 is L-shaped, and the insertion plate 322 is L-shaped to be engaged with the locking groove 212, so that the bearing plate 21 can be prevented from being moved by an external force by the L-shaped locking structure. With this structure, in order to facilitate the installation of the bearing plate 21, the adjusting portion 31 is divided into two adjusting plates abutting against each other in this embodiment, one of which is connected to the insertion plate 322 and the other of which is connected to the receiving plate 321. As shown in fig. 7, which is a member of the connection of the adjusting plate with the receiving plate 321, as shown in fig. 8, which is a member of the connection of the other adjusting plate with the insertion plate 322, the connection portion 32 is composed of both members. Meanwhile, since the adjusting portion 31 is divided into two structures, in order to improve the connection strength, the reinforcing plate 33 is further included, the reinforcing plate 33 includes a first abutting portion abutting against the insertion plate 322, a second abutting portion abutting against the receiving plate 321, and a third abutting portion for connecting the first abutting portion and the second abutting portion and abutting against both the first connecting plate and the second connecting plate. In use, the height of the overhead is determined by the nuts, then the components shown in fig. 7 are installed on the screw, then the end of the bearing plate 21 is sleeved with the reinforcing plate 33 and then is lapped on the bearing plate 321, then the components shown in fig. 8 are installed on the screw, and finally the fastening nuts are installed.
