Claims
We claim:
1. A space enclosing building structure comprising:
a. a plurality of strut members joined at a plurality of vertices
forming a plurality of geometric configurations giving a space grid
structural frame;
b. means at each vertex joining the strut members at each vertex
and for making distance between the vertices adjustable which
includes:
1. a polyhedral member having a plurality of holes;
2.
2. a threaded stud corresponding to each strut member inserted into
one of the holes in the polyhedral member;
3. a threaded plug engaging each threaded stud, an opposite end of
the threaded plug threaded into an end of the strut member; and
c. a plurality of panel members bridging the strut members and
stressed by the frame, each panel having an edge which is
semi-polygonal in cross section which engages the strut, the
semi-polygonal cross section having an extension which joins a
corresponding extension from an adjacent panel
edge. 2. A building structure as recited in claim 1 wherein the
geometric configurations formed includes a tetrahedral-octahedral
matrix and an orthogonal matrix.
Description
BACKGROUND OF THE INVENTION AND PRIOR ART
A number of existing truss networks employ various geometric
configurations. Many of them are bulky and cumbersome and have a
number of parts, such as nuts and bolts, which must be aligned for
assemblage. In the present invention, a number of varying geometric
configurations can be enclosed using sandwiched panel members with
such materials as polyurethane foam sandwiched between plastic
outer layers and held together at the strut members by plastic
semi-polygonal edges which engage the strut under friction with a
spring-like action. Adjacent panels with similar interfaces can
form a seam with the corresponding panel member and can be welded
forming a sealed outer skin.
The structure is useful for building any type of structure for
sheltering humans, animals or other objects or the structure can be
used as a creative toy, in the building of small models to
demonstrate building structures and other uses.
We provide a building structure comprising a plurality of strut
members forming a plurality of geometric configurations with a
plurality of vertices; means joining the strut members at the
vertices; a plurality of panel members bridging the strut members;
and means joining the edges of the panels to the strut members
under spring-like action for frictional engagement with the strut
members. We preferably provide that the strut members have a
polygonal cross section and that means joining the edges of the
panels to the strut members comprises a semi-polygonal member
formed around a cylindrical strut with an angular extension from
the semipolygonal member which is used to form a joint with an
opposite corresponding extension from a semi-polygonal member
adjoining an adjacent panel to the same strut member. The
semi-polygonal member frictionally engages the cylindrical strut,
the panel member maintains the friction. We provide that the means
joining the strut members at the vertices comprises a poly-hedral
member having a plurality of holes; a threaded stud corresponding
to each strut member is inserted into one of the holes in the
polyhedral member; and a threaded plug engages each threaded stud,
an opposite end of the threaded plug is threaded into an end of
each strut member. We provide a building structure wherein the
geometric configurations includes a tetrahedral-octahedral matrix
and an orthogonal matrix.
DESCRIPTION OF THE DRAWINGS AND EMBODIMENT OF THE INVENTION
Other details, objects and advantages of this invention will become
apparent as the following description of the present preferred
embodiment proceeds.
In the accompanying drawings, we have shown a present preferred
embodiment of the invention in which:
FIG. 1 is a geometric configuration showing the building structure
which is composed of two tetrahedra alternating with two half
octahedra;
FIG. 2 is an exploded view showing the components of the vertices
joining the strut members;
FIG. 3 is an elevational view showing a panel bridging three
struts; and
FIG. 4 is a sectional view through a strut member showing two
adjacent panels.
Referring to the above figures, FIG. 1 shows a geometric
configuration of the building structure comprising two tetrahedra
alternating with two half octahedra. It is comprised of strut
members 10 which have a plurality of vertices 12 with a polyhedral
member shown in FIG. 2 generally as 14. Bridging each of the strut
members 10 are panel members 16 which are formed by a
sandwiched-type construction with a stressed skin sandwiching a
lower density core.
FIG. 2 shows an exploded view for joining one of the strut members
10 to the vertices 12. The strut members are polygonal in cross
section and a polyhedral member 14 has a plurality of holes 18 to
receive a stud member 20 which is threaded and is inserted into one
of the holes 18. Threaded to the stud member 20 is a plug 22 which
is also threaded and has a greater outside diameter than the stud
20 but a smaller outside diameter than the strut 10. The plug 22
threads into the strut member 10. These threaded members have the
advantage of adjusting the length of the struts 10 between vertices
12. The polyhedral member 14 also has the advantage of giving the
precise angulation of the various strut members with respect to
each other. The type of angulation and the distances between the
center axis of each of the holes 18 depends upon the type and size
and the geometry required for the particular structure frame
desired. The threaded members which include the stud 20 and the
plug 22 can be pre-inserted in the strut 10 and then those members
adjusted individually to place the desired tension or compression
in the struts 10 so that they are properly stressed with respect to
each other.
FIG. 4 shows the type of assemblage and joint which is used to join
adjacent panel members about the struts 10 and provide an outer
seal. FIG. 4 shows a top end view of a panel 26 and a top end view
of an adjacent panel 28. These panels are comprised of a stressed
skin 32 and a lower density core 30. The edge of the panels 26 and
28 have semi-polygonal members 34 and 35 each having an extension
36 and 38 angularly extending from them. The extensions abut each
other at 40 and form a seam which can be welded and thereby
providing a seal with surfaces 42 and 44 of the panel members 28
and 26 respectively. The semi-polygonal members 34 and 35 as shown
in FIG. 4 frictionally engage the cylindrical struts 10 and extend
the entire length of the panels 28 and 26. It is understood that
variations of this condition about the semi-polygonal members 34
and 35 about the strut 10 can be angled so that the adjacent panels
can be at any angle with respect to each other.
