2. Description of the Related Art A conventional three-dimensional truss frame is formed by assembling one side of a truss as a single member, assembling a large number of members via a connector at a node of the truss, and connecting them one by one, using bolts or screws, or the like. are doing. As the height of the space truss frame becomes smaller, the number of nodes increases dramatically in proportion to the square of the size. Therefore, it is not economically feasible to make a three-dimensional truss frame with a small height. The back of a generally constructed space truss frame is 300 mm or more. Conventional 300
Space truss frames with a height of less than mm are not manufactured. In particular, since mass production of a space truss having a height of several mm to several tens of mm was impossible, no space truss composite plate has been manufactured.

[0003]

The space truss frame is a structural frame that is mechanically advantageous, but is difficult to construct. An object of the present invention is to provide a three-dimensional truss composite plate having required structural strength, which can be efficiently and economically produced.

According to the first aspect of the present invention, in the first and second aspects of the present invention, the three-dimensional core 9 is formed by bending a lattice body 8 such as an expanded metal having a punched-out portion having a quadrangular or hexagonal shape. The three-dimensional core 3 can be manufactured efficiently and economically by an automated machine because it is manufactured integrally from the beginning by processing and does not inherently require a joining operation between the core components. The three-dimensional truss composite plate formed by joining the plate-shaped member 10 to one or both surfaces of the three-dimensional core 9 according to the second aspect of the present invention has four sides shared by four adjacent quadrilaterals. 8a or the tips of the three sides 8a shared by the three adjacent hexagons are joined diagonally to form a quadrangular pyramid or a triangular pyramid ridge,
