Patent ID: 11684159

Abstract:
A composite structural board is disclosed, which comprises a face plate (2), the face plate (2) having a main body portion (2c) that is substantially in one plane and a peripheral portion (2a) surround the main body portion formed by bending the main body portion downwards, the face plate (2) having an upper surface and a lower surface; the board further comprising a base plate (3) provided with a plurality of substantially uniformly distributed and integrally formed protrusions, the lower surface of the face plate (2) being attached to and supported on top faces of the protrusions; and the board further comprising a stiffener (4) for fixedly connecting the peripheral portion (2a) of the face plate (2) and the base plate (3) together, wherein at least a part of the stiffener (4) is fixedly connected to the base plate (3), and at least another part of the stiffener (4) is fixedly connected to at least a part of a lower surface of the peripheral portion (2a) of the face plate. With the above-described structure, the strength of the composite structural board can be further increased while the number of components is reduced, and the production costs are greatly lowered.
