Description

Hollow sheet

The new type relates to a kind of board, especially a hollow board.

Traditionally used as a material shell (for example: trunk shell or 3C product shell), office partition or building materials, it is a solid metal plate, composite plate or plastic plate with a certain thickness.

In order to reduce the weight of the plate, but to maintain the predetermined thickness of the plate to provide the predetermined structural strength as the outer shell or partition of the article, a hollow plate is proposed.

Referring to FIG. 1, one of the common hollow plates currently consists of bonding a number of connecting ribs 92 arranged at intervals between two thin plates 91 spaced apart from each other. However, since the connecting ribs 92 are glued between the thin plates 91 in the manufacturing process, the thin plates 91 need to be prepared first, and then the connecting ribs 92 are separately manufactured; The connecting ribs 92 are arranged and bonded to one of the thin plates 91, and after the bonding is stable, another thin plate 91 is also bonded to it, and there are many manufacturing procedures.

Another common hollow plate uses a honeycomb plate instead of the connecting ribs. Although the steps of arranging the connecting ribs 92 can be saved, the production of the honeycomb plate still needs to be moulded, moulded or cut and assembled. Can not effectively reduce the complexity of the manufacturing process.

In addition, the connecting ribs 92 or the honeycomb plates need to be connected with the thin plate 91 of different materials, which leads to doubts about the structural strength of the hollow plate made.

Therefore, the object of the present invention is to provide a hollow board that can at least overcome at least one of the disadvantages of the prior art.

The hollow plate includes a first plate and a second plate.

The first plate includes a first plate body portion, a plurality of first openings spaced apart and passing through the first plate body portion, and a plurality of first openings that are spaced apart and respectively protrude integrally from the first plate body portion. A supporting piece part, each first supporting piece part is located at the side edge of the respective first opening.

The second plate includes a second plate portion, a plurality of second openings spaced apart and passing through the first plate portion, and a plurality of spaced apart and integrally protruding from the second plate portion The second supporting piece portions, each second supporting piece portion is located at the side edge of the respective second opening, and is connected to the first plate body portion.

The effect of the present invention is to utilize the design of the first supporting piece portions and the second supporting piece portions to omit the connecting ribs and the honeycomb plate, thereby effectively reducing materials. In addition, since the first supporting piece portions and the second supporting piece portions are directly cut and bent from the first plate and the second plate, the connecting ribs and the honeycomb plate do not need to be separately manufactured, and The manufacturing method of the hollow board is simple and rapid, and the structural strength can be maintained.
