Example 1:
referring to fig. 1 to 6, an embodiment 1 of the circular-arc profiled hollow steel sheet according to the present invention includes two profiled steel sheets fixed together to form a hollow structure, and the two profiled steel sheets are nested and engaged with each other. Specifically, the locking plate comprises a locking plate 1 and a buckling plate 2. Each locking plate 1 is formed by bending at least one steel plate. Each buckling plate 2 is formed by bending at least one steel plate.
The locking plate 1 is provided with a plurality of cavities I11 with downward openings along the horizontal direction, and the cavities I11 are formed in a shape of a section with a top end horizontal and a lower end in an inverted trapezoid by bending the locking plate 1 for multiple times; the first cavity 11 is horizontally symmetrical along the vertical axis. And a locking plate gap 12 is arranged between the outer walls of every two adjacent cavities 11.
Through the nesting and matching connection of the support body 21 and the cavity I11, after the arc-shaped profiled hollow steel plate is pressed, the support body 21 is tightly attached to the cavity I11, and the side wall of the cavity I11 and the support body 21 provide vertical support. Specifically, the outer wall of the first cavity 11 is abutted to the outer wall of the adjacent first cavity 11 along the horizontal direction, the locking plate gap 12 is closed, the stress in the vertical direction is converted into the stress in the horizontal direction, and the pressure bearing effect is improved. Simultaneously, the setting of cavity and cavity 11 in the supporter 21 can isolated the air flow to a certain extent, plays fire-retardant effect, simultaneously, has also slowed down the propagation of sound wave in the vertical direction, plays sound-proof effect.
In this embodiment, the bone plate 2 is a single layer, and the bone plate 2 includes a plurality of horizontally disposed support bodies 21 protruding upward in the vertical direction, and the support bodies 21 have cavities therein. In this embodiment, the arc-shaped support body 21 is formed by bending the bone plate 2 multiple times to form a first arc edge 241 and a second arc edge 242 which are symmetrical along the vertical axis and convex in the horizontal direction, and forms a cavity in the support body 21, thereby forming a symmetrical pressure-bearing effect.
When the locking plate 1 is pressed after being connected with the bone buckling plate 2, the two arc edges expand and expand towards the horizontal two end directions respectively and are abutted against the inner wall of the first cavity 11. The outer wall of the first cavity 11 is abutted with the outer wall of the adjacent first cavity 11 in the horizontal direction, and the locking plate gap 12 is closed. The arc edge of the support body 21 can be expanded to the horizontal direction when being pressed, and elastic or plastic deformation is generated, so that reaction force is provided, the reaction force can provide a component in the vertical direction, and the pressure bearing capacity of the arc-shaped profiled hollow steel plate is improved.

When the locking plate 1 is connected with the bone buckling plate 2 and then pressed, the top opening of the second cavity 13 deforms to form a closed state and moves downwards, so that the side wall of the second cavity 13 deforms to form a stable structure with a triangular cross section.
The bottom end of the cavity in the support body 21 is provided with a gap, when the locking plate 1 is connected with the bone buckling plate 2 and then pressed, the support body 21 is expanded along the horizontal direction, and the gap is reduced. The reduced gap allows a reaction force to occur at the bottom end of the support body 21, thereby converting the vertical stress into the horizontal stress.
The minimum included angle between the outer side wall of the support body 21 and the horizontal direction is alpha, alpha is greater than or equal to 45 degrees, and in the embodiment, alpha is equal to 45 degrees.
The upper surface of the profiled hollow steel sheet is paved with a decorative panel (not shown in the figure), and the panel is made of glass.

The support body 21 comprises a first support unit and a second support unit which are arranged in a stacked manner, and the first support unit and the second support unit are formed by continuously bending the buckling plate 2.

In this embodiment, a support gap 23 is provided between the second support units of every two adjacent support bodies 21, and the outer wall of every two adjacent support units can be deformed in the horizontal direction to abut against each other after the profiled hollow steel sheet is subjected to a vertical pressure. The arrangement of the first supporting unit 215 and the second supporting unit 216 not only enables the buckling plates 2 to be sequentially connected in a nesting and matching manner, thereby improving the pressure-bearing capacity by times, but also can provide more cavities, slow down air circulation and provide better flame-retardant and sound-insulation effects. Meanwhile, due to the arc-shaped design of the first supporting unit 215 and the second supporting unit 216, the included angle formed by each side can be used for providing elastic or plastic deformation when being pressed, so that the pressure bearing capacity is increased.
