[0019] Example

[0020] Reference Figure 1-4 As shown,

[0021] A top-mounted structure for a prefabricated substation includes fixed seats mounted on the top surfaces of two walls perpendicular to the ground. The lower ends of the fixed seats are fixed to the upper ends of the walls by bolts. A receiving seat is fixed to the top surface of the fixed seats, and a groove is formed on the top surface of the receiving seat. A roof panel is mounted above the receiving seats, and the distance between the roof panels gradually increases from the top to the bottom. A plug-in plate is fixed to each roof panel and inserted into the groove on the top surface of the receiving seat. The plug-in plate fits snugly into the groove on the top surface of the receiving seat. A roof retaining strip is provided between the roof panels. The roof panels can be quickly assembled with the walls by inserting the plug-in plate into the receiving seat fixed to the top surface of the wall.

[0022] The sidewalls of the receiving seats, which are close to each other, have multiple evenly distributed grooves. The receiving seats are connected by crossbars inserted into the grooves. The crossbars are parallel to the horizontal plane, and both ends of the crossbars are in close contact with the grooves on the sidewalls of the receiving seats. The top surface of the middle part of the crossbar has an internal threaded groove, which is screwed into a screw located above the crossbar. A T-shaped plate is fixed to the top surface of the screw. The T-shaped plate is perpendicular to the horizontal plane, and its top surface has a groove. The crossbars connecting the receiving seats and the T-shaped plates threaded to the crossbars can form a frame structure that supports the roof slab, thus providing support for the roof slab.

[0023] The roof clip includes a top plate and a fixing plate. The bottom surface of the top plate is attached to the roof plate. The fixing plate is fixed below the top plate, and its side wall is attached to the side of the roof plate that is close to it. The fixing plate passes through a groove on the top surface of the T-shaped plate, and the groove on the top surface of the T-shaped plate is fixed by a bolt that passes through the T-shaped plate. A first reinforcing plate and a second reinforcing plate are fixed to the side of the roof plate that is close to each other. The bottom surface of the first reinforcing plate is attached to the top surface of the T-shaped plate, and the second reinforcing plate is located above the first reinforcing plate, with its bottom surface attached to the top surface of the first reinforcing plate. Both the first and second reinforcing plates are penetrated by the roof clip.

[0024] The roof clamping strip passes through the first and second reinforcing plates, and then passes through the T-shaped plate and is fixed to the T-shaped plate by bolts, which can further reinforce the roof plate and improve the service life of the box-type substation. The roof plate can play a part in fixing the roof plate.
