~ 1 ~
The invention relates to a wall oP pref~bricated wall
units with closed rectangular frames.
The conventional arrangements for buildings which can
be assembled from prefabricated units, for stiffening the
building comprise diagonal braces in the individual structural
units which absorb lateral wind load in the assembled
structure. The diagonal reinforcements interfere with a free
choice of arrangement for windows and doors, and appropriately
fashioned units are required. Introducing insulating material
into the units is made difficult by such bracing. The
acute-angled corners formed by the bracing can be filled with
insulating material only with difficulty and/or by taking
considerable time so that often cold-conducting bridges are
formed at these locations. Likewise, the subsequent window or
door placing is difficult. Manufacture of these units is
substantially more expensive because of these diagonal braces
with the many inclined cuts involved and, as a consequence of
the differently designed windows and door units, requires
variegated bracings and/or trimmed components.
DOS 2/143,579 discloses wall units and ceiling units
made of wood which are rigidified on the inside by
perpendicularly intersecting strips and are lined on the outside
with panels. Corner units have the same structure. This
building mode suffers from the drawbacks described above.
DOS 2,627,261 describes a wall construction composed

2,~
of joined profiled members~ especially of metal, where the
interstices are filled with concrete. This construction is very
expensive and uneconomic.
Wall and corner units consisting of beams are known
from W0 8~/05485. The strength of these units can be achieved
solely by the dimensioning o~ the individual components. This
entails considerable expenditure in material.
Herein described is a novel design of corner units,
with wall units having a simple structure which exhibit good
stiffness but do not limit the placing of doors, windows, and
the like.
In a wall of the type described the corner units have
braced and/or rigidified frames meeting at an angle to one
another.
Using such corner units, the wall unit~ can be
designed as simple, rectangular frames. The cornar and wall
units can have any desired design of outside or inside lining.
More particularly in accordance with the invention
there is provided a wall for a building composed of
prefakricated wall units having closed rectangular frames, and
corner units joined thereto, the corner units comprising braced
and/or rigidified frames meeting at an angle with respect to one
another.

Embodimen~s of ~he invention will now be described
with reference to the accompanying drawings, wherein:
Figure 1 shows a building in perspective view with a
roo~ indicated by dashed lines,
Figures 2 and 3 show two embodiments in plan view,
Figure 4 show~ in an oblique view, and
Figure 5 shows, in plan view, prefabricated components
embodying this invention made of wood.
Descri~tion of the Preferred Embod ments
As illustrated in Figures 2 and 3, for a pre~abricated
building, wall units 2 can be laid *lush with the outsides of
the corner units 1, or they can be placed offset toward the
inside, as in Figure 3, so as to particularly emphasize the
corners o~ the building. This method of construckion of~ers a
great variety of design possibilities and great adaptation to
the prevailing purpose of use ~or the building.
For example, buildings for commercial purposes can be
lined on the outer walls with shaped aluminum panels, and the
corner units 1 can be lined with enameled metal sheets of any
desired color. For residential purposes, mixed designs can be
executed, some with wall units placed flush and some offset
toward the insid2 (Figure 3).
Further, concrete corner units 1, or corner units 1
lined or faced with enameled metal panel~ give additional design

possibilities in conjunction with wall units 2 which are faced
with wood.
An important criterion for a rugged corner design
which is to withstand the shear caused by wind load is that the
corner units l consist of angularly arranged frames 3, as
illustrated in Figure 4. The bracings 4 of these frames extend
obliquely downwardly toward the apex of the angle formed by the
frames 3. These bracings transmit the shear toward the floor.
Each of the two frames 3 is subdivided in this arrangement by a
cross brace 5. With a ratiQ of width to height for the frames 3
of 1 : 2, and with a cross brace 5 located in the center of the
height dimension, two respective square component frames are
obtained, and the bracings 4 extend downwards at 45.
Where a corner unit 1 is made of wood, the two frames
3 are joined at a corner post 6, most preferably by screws or
bolts. The wall units 2 here are likewise made of wooden frames
and are preferably joined at their respective uprights to the
respective frame 3 by means of screws or bolts. The frames 3
and the wall units 2 have a uniform width, for example of
llO cm. All of the units are preferably connected at their
bottom plates by screws or bolts to the floor, for example a
concrete floor.
Corner units 1 of steel or rein~orced concrete have
the same structure as can be seen from Figure 4 showing the
wooden construction. The only difference is that the frames 3
are joined directly at the apex of the meeting angle, i.e.
without a specific corner post member.
