ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a polygonal building structure enclosing an inner courtyard in which a central staircase is connected by passages to the surrounding building structure.
2. Description of the Prior Art
In polygonal buildings of this type, the individual building sectors and the stories in these building sectors are not laid out in such a manner that the initial structure need not be altered with a change of its size and where, moreover, all the building sectors and stories may be reached at any level from the central staircase.
The building construction according to German patent No. 2,065,437 comprises building sectors of rectangular horizontal cross section, rather than the trapezoidal construction, which makes ready expansion possible. Nor does it involve a spiral construction matching the vertically upwardly winding staircase to vertically staggered stories in the adjacent building sectors.
European patent No. 118,723 discloses a parking garage having a cylindrical outer wall and an upwardly winding spiral driveway.
SUMMARY OF THE INVENTION
It is one of the objects of this invention to provide a polygonally shaped building with building sectors facing south, west, north and east.
It is another object of the invention to provide a multi-story building structure composed of trapezoidal building sectors with vertically staggered stories which form a spiral and forming a ring around a central staircase. Such a ring, divided into trapezoidal building sectors, may change its circumference and may be expanded to any desired size without changing the basic structure of the building sectors. If successive stories are so staggered vertically that they form an upwardly winding spiral, a three-dimensional structure is obtained which maintains its basic structure at any size. The polygonal shape may be a triangle or any other polygon, such as a pentagon or a hexagon. To obtain the desired vertical staggering of the stories in the adjacent building sectors, the ground floors in the adjacent building sectors continuously increase in height. Connecting passages radiate from the central staircase to the vertically staggered stories.
The above and other objects are accomplished according to the present invention with a building comprising a plurality of multi-story building sectors, each building sector having a trapezoidal horizontal cross section and the building sectors forming a polygonal ring enclosing an inner courtyard, a staircase housing in the inner courtyard, a spiral staircase in the staircase housing, the staircase winding circularly in an upward direction, and connecting passages radiating from the staircase to respective ones of the stories of the building sectors at staggered vertical distances. Successive stories in the upwardly winding direction of the spiral staircase in adjacent ones of the building sectors are vertically staggered from each other by the same vertical distances as the connecting passages.
According to one feature, the connecting passages are uniformly distributed around the staircase housing. The building sectors may be arranged about a common center and extend over identical angles with respect to the common center. If desired, at least one group of building sectors has a different distance from the common center than other building sectors.
