Abstract

ABSTRACT

PREFABRICATED UNIT BUILDING WALL

A wall consisting of corner units (1) and wall units (2) where the corner units are frames (3) meeting at an angle, and have oblique bracings (4) and cross braces (5) and are connected with one another in the zone of the meeting angle by corner posts (6) or the equivalent. The wall units (2) have rectangular frames.

Description

;~ t~ ~ ~ ;J r j ~

~ 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.

2 ~ ~ ~ ' i ? j 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 . ' ' ` ' .

i(s~J~j 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.
