PREFABRICATED BUILDI NG Filed sept, 22, 1937 infinitif lllnfnnrrl Patented Feb. 21, 1939 UNITED STATES PATENT OFFICE PREFABRICATED BUILDING Application September 22, 1937, Serial No. 165,098

13 Claims.

Myinvention relates to prefabricated buildings. It has heretofore been proposed to construct buildings having inner wall facings, such as plastering, secured to the walls by a sheet or sheets 5 of an-choring or clinching material fixed to the inner faces of prefabricated panels comprising the Walls. This anchoring material has heretofore been in the form of individual sheets substantially coextensive with the panels comprising the wall structure or has been in the form of continuous sheets extending over the area of several adjacent panels. As a result, the sheets of reenforcing material cause difficulty at the inside corners when the plastering is applied, making an irregular and bulky corner which it is difficult to plaster satisfactorily with an even and long enduring coat of plaster, due to the necessary spacing connections between adjacent individual sheets when the latter ter- 20 minate in the corner, and due to the need for the supplemental steel rod or rods required to locate the sheet when a single sheet is carried around the corner. This diiculty with a bulky corner is also emphasized by the usual provision of a felt strip in the corner over the metal frame between adjacent panels to prevent condensation.

My invention has among its objects to eliminate the above difficulties and markedly improve the corners formed in the interior of pre- 30 fabricated buildings. A further object of my invention is to provide an improved construction whereby it is made possible to eliminate the previous bulky inner corners and apply plaster to a wall having anchoring or clinching means, such as sheets of reticulated metal, while making a clearly defined and accurately formed longlived corner of the plastering. A still further object of my invention is to produce a corner structure which has the above advantages, and 40 the additional advantages of insuring a rm and even bond between the plaster and the Wall members at the corners, and enabling the plaster to maintain the shape of the corners without tending to crack or pull away from the inner wall surface. These and other objects and advantages of my improved construction will, however, hereinafter more fully appear.

In the accompanying drawing, I have shown for purposes of illustration one embodiment Which my invention may assume in practice.

In this drawing,-

Figure 1 is a perspective view of an inside corner of a buildingV embodying my improve- 55 ments, the view being toward the ceiling;

Fig. 2 is a perspective view of a like inside cor ner, looking toward the floor, and

Fig. 3 is a detail perspective view of the strips of fine mesh at the corner junction in Figure 1.

In this illustrative construction, it Will be noted 5 that suitable channel members I carry the usual insulating wall panels 2 and are arranged in a conventional manner together with a channel member 3 to forma corner post. A usual felt stripping i is supported on the inner exposed 10 surface of the metal of the channel members I forming the post, in order to prevent condensation of moisture on the wall, -due to dierences of temperature on the opposite sides of the same, While over this felt strip my improved plaster supporting corner structure is disposed.

In my improved construction, anchoring material 5, herein reticulated metal, is applied to the inner walland ceiling in continuous strips which are terminated at each inner corner; i. e., at corners formed between the outer walls and partition walls and between the side walls and ceiling. The anchoring material 5 is spaced from the wall panels 2 preferably by rods 6 which may extend into Lipper and lower channels receiving the corresponding edges of the panels, the upper channels being shown at '1. Further, the adjacent edges of the different strips of material overlie the felt strip il, preferably With these edges adjacent one another but not overlying one 3o another, in such manner as thereby to minimize bulk in the corner.

In erecting the wall, when the felt stripping 4 has been placed as desired, the anchoring material 5 is next applied and fastened to the panels 35 by holding Wires 8, which may be inserted through suitable apertures in the insulating boards 2, forming the wall panels, and twisted together over similar rods 6 on the outer surface `of the wall, in the same manner employed with 40 previous anchoring material carrying units. After the wall panels have been erected in the frame, the exposed metal has been covered with felt stripping, and the anchoring material has been fastened to the panels, in my improved construction, I next apply a corner strip 9 of fine mesh anchoring material. This strip is usually bent at right angles along the center to fit within the corner of the walls and extend over and cover the edges of the sheets of anchoring material 5 along the entire length of the corner edges.

I also preferably hold the strip 9 in place by tacki'ng the same to therpanel boards 2, with short nails l0 or with other suitable fastening means,

so as to form a rm base for plastering ll.

As shown in Figure 1, a strip 9 of like fine mesh anchoring material is also placed along each junction between the reticulated metal 5 on the side wall and similarly disposed metal on the ceiling I2, as well as along the length of the vertical corner between the side walls.

As shown in Fig. 3, the edges of the strips 9, 9 are preferably overlapped where they join with the side Walls so as to present a clinching surface for the plaster and form a clear and even surface to the very point of the corner. It will be understood that the strips 9, 9' may be intertted in any other suitable manner than by overlapping the edges, as long as the strips do not destroy the even surface of the corner structure.

As a result of my improvement, it will be noted that not only is the support for the plastering increased in each corner, but that the plastering is more readily and easily applied to a corner on account of the gripping effect of the finer mesh of the extra strip of anchoring material and because it conforms more closely with the corner. Note further that this results in a more accurately formed and smoother corner where the plastering is applied and a corner which will not tend to crack or show other signs of an inadequate subsurface for the plastering. Attention here is particularly directed to the elimination of unequal depths of plaster and of rounded or sagging corners which might result from the use of previous constructions which are difficult to make conform to sharp corners. Also, stopping and cutting the roll of mesh at the corners facilitates the handling of the heavy rolls and the fastening of the mesh to the panels. These and other advantages of my improved construction will, however, be clearly apparent to those skilled in the art.

While I have in this application specifically described one embodiment which my invention may assume in practice, it will be understood that this form is shown for purposes of illustration, and that the same may be modified and embodied in other forms without departing from its spirit or the scope of the appended claims.
