To provide a sheet of hyperboloidal body construction by cylinders contacting with each other which is capable of using for a flower pallet, a chair, a table, a monitor stand and polygonal pyramid roof frame or the like and which is simply capable of assembling by minimizing the number of members and lessening machining as compared with a conventional support stand.

If the number of cylinders, diameter of a cylinder and slope angle are given, the cylinders consisting of plural numbers of four or more completely touch each other along perimeters of an inscribed circle and circumscribed circle which are uniquely computed. Thereby, it is discovered to be capable of theoretically configuring a sheet of hyperboloidal body construction which is maintained in an equilibrium and furthermore means for maintaining the construction is developed.
