SECTIONAL WOOD BUILDING Patented Oct. 3, 1944 SECTIONAL WOOD BUILDING Neal T. MacKenzie, St. Paul, Minn, assignor to General Timber Service, Inc., St. Paul, Minn., a

corporation of Delaware Application March 2-0, 1942, Serial No. 435,539 9 Claims. (01. 20-12) This invention relates to a sectional wood building particularly although not exclusively adapted for use as a grain storage bin.

It is an object of the invention to provide a Wooden building having a multiplicity of novel wall units adapted to form a substantially cylindrical structure which will withstand outward pressure from within such as that produced when the building is filled with grain.

Another object is to provide in a building of this class novel, prefabricated wall sections adapted to be erected and fastened together quickly and easily.

A further object is to provide for such buildings an improved joint which will remain closed under severe outward pressure and other stresses to which it is subjected, including those due to the swelling and shrinking of the wood.

Referring to the accompanying drawings:

Figure 1 illustrates one of my improved buildings in elevation;

Fig. 2 is a partial plan View of the same with portions of the floor and roof removed;

Fig. 3 is a front elevation of a panel or wall section having a door opening;

Fig. 4 is a side elevation showing a vertical edge of one of the wall panels;

Fig. 5 is a front elevation of one of the panels with portions of the exterior sheathing removed;

Fig. 6 is an end view of one of the panels;

Fig. 7 is a fragmentary section taken on the line 'l! of Fig. 2 and on a larger scale;

Fig. 8 is an interior elevation of one of the metal fastening devices and adjacent portions of a vertical joint between panels; and

Fig. 9 is a horizontal section taken on the line 9-9 of Fig. 8.

As shown in Figs. 1 and 2, my improved building has a multiplicity of plane, rectangular wall panels l joined together at their vertical edges to form an approximately cylindrical enclosure. The lower edges of the several panels rest on a suitable floor ll provided with joists l2 resting on posts 13 or other suitable foundation members. A sectional roof l4 and a ventilator l are also provided but the present invention does not relate to these parts of the building or to the floor construction.

As best shown in Figs. 4 and 5, each of the wall panels i0 is formed from horizontally extending, interior sheathin members It and vertically extending, exterior sheathing members I! secured together in overlapping relation. The several members l6 and I1 are preferably constructed from stock of nominal one inch thickness, with the wood grain extending longitudinally as in ordinary lumber. Tongue and groove connections are preferable between members I! and the entire surfaces of contact between these outer members and the inner members l6 may be glued to increase the rigidity of the panels; although nailing of the inner and outer members together has been found to be sufficient in most cases.

The door panel shown in Fig. 3 is like the others except that it has a suitable rectangular opening l8 formed by cutting away portions of outer sheathin members l9 and inner sheathing members 20. To afford an ample number of continuous reinforcing members crossways of the door, a number of the inner sheathing members 2| are extended entirely across the door opening and panel.

Extending parallel to each of the vertical edges of the several panels I0 is a row of holes 22 for bolts 23. These holes are spaced a substantial distance from the vertical edge surfaces 24 of the panels and these surfaces are formed to lie in vertical planes through the center of the building and to fit together, as best shown in Fig. 9. Each joint between panels has a batten strip 25 covering the end portions of the adjoining members on their inner surfaces from top to bottom and a number of rigid bars 26 extend across each of the strips 25 to coact with the bolts 23 in fastening the panels together. Offset ends 2! of each bar 26 are adapted to be impressed into the inner surfaces of the sheathing members Hi and each bar has a pair of perforations to receive a pair of the bolts 23 which converge in ward and have nuts 28 threaded on their inner ends. The holes 22 are preferably arranged to extend substantially perpendicularly to the panels in which they are formed so that when the adoining panels are erected at an obtuse angle to each other the projecting inner ends of each pair of bolts 23 converge at an acute angle to each other.

As shown in Figs. 2 and 7, anchor strip 29 may be fastened in spaced, parallel relation to the outer edges of the floor H so that the lower edges of the panels I!) may be placed in abutment with these strips. A door 30 (Fig. l) of ordinary or suitable construction is provided for the opening l8 of the door panel.

Mass production of my improved buildings is facilitated by prefabricating the several wall panels in appropriate sizes so that these plane, rigid units may be stored and shipped compactly and handled and erected easily by two men. It

will be understood that such prefabrication involves the use of jigs and line production methods which insure uniformity in dimensions and accuracy in operations such as the drilling of the holes 22 in the several panels. To erect one of my improved buildings, the foundation and floor may be constructed in the usual manner and then the floor strips 29 may be fastened in place. The batten strips 25 may be fastened to alternate panels as part of the prefabricating operation or they may be attached at any time before the panels are erected.

The panels II] are erected successively in engagement with the outer surfaces of the several strips 29. nected to another by appropriate manipulation of the bolts 23 and bars 26, the edge surfaces 24 being drawn into abutment with each other by inserting the bolts 23 in the perforations 22, applying the metal bars 26 to the inner ends of the bolts and tightening the nuts 28. As the bolts 23 converge inward, the application of the bars 26 to the inner ends of these bolts may be acthe roof l4 and ventilator l5 may be constructed or fastened in place.

v It will be evident that I provide a number of vertically spaced rows of inner sheathing members extending, end to end, completely around the As each panel is placed it is con strip overlapping the inner surfaces of the ends of said members and means for fastening said units together comprising a multiplicity of metal bars extending across said batten strip in contact therewith and severally in engagement with said sheathing members of the respective units and means connecting theend portions of said bars to said units respectively.

3. In a wood building of the class described, a

plurality of Wall units disposed at an obtuse angle to each other and each having wood members disposed end to end with such members of the adjoining unit, a strip overlapping the inner surfaces of end portions of said members and means for fastening said units together comprising a metal bar extending across said strip in contact therewith, ofi'set end portions on said bar adapted to be impressed into the wood of the adjoining members of the respective units and means connecting said bar to said units respectively and for forcibly impressing the end portions of said bar into said members.

4. In a building of the class described, a plurality of plane substantially rectangular wall units disposed at 'an obtuse angle to each other and each having horizontally extending inner sheathing members overlapping and secured to vertically extending outer sheathing members and means for joining the side edges of said units together comprising a strip overlapping the several inner sheathing members along the joint, a plurality of metal bars extending across said edges in engagement with said strip and with inner sheathing members of the respective units and means connecting the end portions of said 7 bars to said units respectively.

building and the members in'each row are joined I tially removed from the edges of the panels. By

this arrangement a part of the stress which would otherwise be applied to the bolts 23 is distributed directly to the horizontally extending wood members.

It will be understood that the vertical load is borne by the outer sheathing members I! wherein the grain of the wood extends Vertically. Having described my invention, what I claim as new and desire to protect by Letters Patent is:
