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.

First claim

I claim:

1. A structural board, comprising:
a face plate comprising a flat main body portion and a peripheral portion around the main body portion perpendicular to, and joined at a right angle to the main body;
a base plate having a plurality of protrusions, a lower surface of the face plate attached to and supported on a top surface of the protrusions;
a stiffener adjoining the peripheral portion and the base plate ( 3 );
the stiffener having a closed shape cross-section; and
a top surface of the stiffener abutting a bottom surface of the base plate, and the stiffener having an outermost vertical surface contacting at least a part of the peripheral portion of the face plate.

2. The structural board of claim 1 wherein the stiffener comprises a hollow structure having a rectangular cross-section, the top surface of the stiffener is parallel to the main body portion,
the stiffener having an integral flange at an intersection of outermost vertical surface and a bottom side of the stiffener, the integral flange projecting horizontally outward from the outermost vertical surface; and
a lower edge of the peripheral portion abutting a top surface of the integral flange on the stiffener.

3. The structural board of claim 2 wherein an outer end of the flange is flush with an outer surface of the peripheral portion.

4. The structural board of claim 2 wherein the entire peripheral portion is straight and parallel to the outermost vertical surface of the stiffener.

5. The structural board of claim 2 wherein the peripheral portion contacts the entire outermost surface of the stiffener above the integral flange.

6. The structural board of claim 2 wherein the base plate has a perimeter portion without protrusions, the perimeter portion having a recess portion with a flat bottom surface, the recess portion has a width greater than the stiffener, and a top surface of the stiffener is adjoining the bottom surface of the recess portion of the base plate ( 3 ).

7. A structural board, comprising:
a face plate comprising a flat main body portion and a peripheral portion around the main body portion perpendicular to, the main body;
a base plate having a plurality of protrusions, a lower surface of the face plate attached to and supported on a top surface of the protrusions;
a hollow stiffener adjoining the peripheral portion and the base plate, a top surface of the stiffener parallel to the main body portion and abutting a bottom surface of the base plate, the stiffener having an integral flange at an intersection of an outermost vertical surface and a bottom surface of the stiffener, the integral flange projecting horizontally outward from the outermost vertical surface of the stiffener;
the peripheral portion straight and parallel to the outermost vertical surface of the stiffener, the stiffener having an outermost vertical surface contacting at least a part of the peripheral portion of the face plate, a lower edge of the peripheral portion abutting a top surface of the integral flange.

8. The structural board of claim 7 wherein the peripheral portion contacts the entire outermost surface of the stiffener above the integral flange.

9. The structural board of claim 7 wherein an outer end of the flange is flush with an outer surface of the peripheral portion.

10. A structural board comprising:
a face plate comprising a flat main body portion and a peripheral portion around the main body portion perpendicular to the main body;
a base plate having a plurality of protrusions, a lower surface of the face plate attached to and supported on a top surface of the protrusions;
a stiffener adjoining the peripheral portion and the base plate, the stiffener having a hollow closed shape cross-section, a top surface of the stiffener parallel to the main body portion and abutting a bottom surface of the base plate, the stiffener having an integral flange at an intersection of an outermost vertical surface and a bottom surface of the stiffener, the integral flange projecting horizontally outward from the outermost vertical surface of the stiffener;
the entire peripheral portion straight and parallel to the outermost vertical surface of the stiffener, the stiffener having an outermost vertical surface contacting at least a part of the peripheral portion of the face plate, a lower edge of the peripheral portion abutting a top surface of the integral flange; and
the peripheral portion contacting the entire outermost surface of the stiffener above the integral flange.
