[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-Figure 3 , an embodiment provided by the utility model:

[0019] Embodiment 1: A cavity thin plate structure includes a panel 1 and reinforcing ribs 14 . A fixing plate 12 is installed on an outer wall of one side of the panel 1 . A cavity 13 is opened inside the panel 1 . A cover plate 11 is provided on an outer wall of an upper end of the panel 1 .

[0020] The fixing plate 12 is designed in a rectangular shape, and the size of the fixing plate 12 is larger than the size of the enclosure 1. The fixing plate 12 is used to connect the enclosure 1 with an external column or equipment to maintain the use height and position of the enclosure 1.

[0021] The outer wall of the fixing plate 12 is provided with fixing holes distributed in a rectangular array, and expansion screws are provided inside the fixing holes. The expansion screws penetrate the fixing holes and are connected to the external column or the inside of the equipment to fix the enclosure 1 and the fixing plate 12, and keep the use position of the enclosure 1 stable.

[0022] The inner wall of the cavity 13 is installed with equidistant and parallel reinforcing ribs 14, which are designed with 4mm steel plates to ensure the support force on the inner wall of the cavity 13 and to disperse the application of prestress. The upper end surface of the reinforcing rib 14 is in a horizontal state with the upper end surface of the enclosure 1. The reinforcing rib 14 cooperates with the cavity 13 to ensure that the prestress is evenly applied in the entire structure to avoid local stress concentration.

[0023] The size of the cover plate 11 matches the size of the enclosure 1. The cover plate 11 shields the upper end of the enclosure 1, protects the cavity 13 and the reinforcing ribs 14, and ensures that the interior of the cavity 13 is clean.

[0024] The inner wall of the cavity 13 is designed in an inclined shape, and the shape of the reinforcing rib 14 is adapted to the shape of the inner wall of the cavity 13. The reinforcing rib 14 forms a supporting shape inside the cavity 13 to support the cover plate 11 and the enclosure 1, maintain the overall shape of the enclosure 1 stable, and form a layout that resists prestress. The prestress is evenly distributed inside the cavity 13 and the enclosure 1. The cavity 13 and the reinforcing rib 14 form an internal prestress field, so that the entire plate can resist part of the tensile stress and shear stress in advance when it is subjected to external loads, which can effectively improve the seismic performance, improve the overall strength and rigidity, reduce the amplitude of the plate itself, and improve the toughness of the plate itself, improve the adaptability of the plate to the use environment, and can reduce the weight while maintaining its own strength, which is convenient for transportation and installation after production.
