REENFORCED FABRICA'IED METAL PLATE WALL SECTION.
Application filed December 21. 1921. Serial No. 523,922.
Heretofore in constructinglarge rooms, boxes, coal bunkers, coal cars and thelike with fabricatedmetal sheets to form the walls of such'structure, particularly where they are subject to internal and external pressure of any kind, whether it is from intense heat or from compacting the contents Within the enclosure, the walls are not capable of giving or yielding to take care of such pressure. In such constructions, it
' is customary to fabricate the metal sheets by' attaching them to heavy steel channels, angles, I beams, girders and the like which have appropriate flanges to receive the attaching means orrivet-s. angle irons, I beams, girders and the like are employed for the purpose of stiffening or reenforcing the wall, considerable reliance being at'present invariably placed on a main I beam anchored at the top and bottom.' In fact upon this I beam the safety of the entire structure depends.
However a construction of this character is not only clumsy and expensive, but Is not,
at all expansible from heat, or capable of giving or yielding. Furthermore such walls for use in the construction'of coal bunkers,
rooms, boxes Iand-the like are not practical,
when made up in sections/and shipped to the place Where the. structure is to be installed, due to the I beams, channels'or girders being heavy, which will make the freight rates a very large item in the cost.
of getting such fabricated wall sections to the place Where they are to be used.
.In building walls of .such material, it 1s necessary to ship it in disassembled quantities, and whenit reaches the various places where it is to be used, the Work of constructi ing the wall entailsconsiderable labor, due to the sheet sections. being separably' installed? Such walls are constructed with I i beams arranged at rightangles, intersecting 'each other, with the metal sheet sections connected to the I beams. Though there are no illustrations of this character of wall, it .is possible to 'gather the foregoing method of construction, and therefore. those interested in the artof' reenforced fabricated metal sheet walls may readily understand the above disadvantages, and impractical fea tures.
The present invention aims to embody a reenforcement of an ex pansible or yieldable character, though not necessarily, from portions of the fabricated sheets or metal plates These channels,
themselves, when fabricated as Will be hereinafter explained and illustrated.
1n adopting a reenforcement as made from the plates themselves, it is the aim to form the reenforcement by constructing corrugations in the plates at infrequent intervals, extending at right angles to each other, some being formed in succession, I
-while others, as previously stated are infrequently arranged. v
It is obvious that certain of the reenforce ments or 'stifl'eners of the fabricated metal plates of a Wall section are rigid, while others are expansible, due to certain reenforcements extending at right angles to others. portions of the platesthemselves standing out at variable distances, as nearly as possible at right angles to the plane of the wall section formed of such plates.
Still another purpose is the provision of a wall section. made up of strong relatively thick metal plates or sheet metal material that often goes to waste in a plate shop because of its narrow width precluding its use in ordinary structures, and in this case the metal plates may not only be corrugated at infrequent intervals to provide an expansible or yieldable reenforcement, but may be' fabricated together by expa'nsible or yieldable reenforced connecting plates.
The. reenforcements are formed of.
As a further purpose it is the aim to proup of fabricated plate metal of uniform width, capable ofbeing stored in factory I warehouses, as stock material, whereas the Wall sections employing I, channel and an-. gle beams or girders are incapable of being stored, in order to utilize asmall space.
Furthermore wall sections made up in this manner cannot be handled as easily as can the wall sections, wherein the expansible or lll) yieldable Qreenforcements or stiffeners are employed.
A still further purpose is the provision of a fabricated plate wall section, wherein.
riveting and punching are very materially reduced, and in some instances eliminated altogether, in view of the fact that the fabricated plate metal can be welded together, which is practically impossible where the wall sections are constructed with I, channel and angle beams or girders.
As previously stated the present construction of wall section insures a saving in weight alone, ,which permits an installation of such material in large projects at a relatively low cost, and this is especially true when such materials are exported into foreign countries.
In constructing a wall section of the present character unlimited variations are thus secured with materials readily at hand and very often of little value except as scrap.
Additionally the invention aims to provide a plurality of wall sections, wherein they may be united, either at right angles, or at obtuse angles, or in other positions, and in such cases may be welded in position, for the purpose of connecting the wall sections, which are also made up of fabricated plate metal having stiifeners of the present form.
In constructing wall sections of the present character, it is the aim to employ any suitable means, preferably forming dies shown in Letters Patent Nos. 1,534,299 and 1,535,295; and which dies are of such construction and shape as to form stiffening corrugations or reenforcement, such as illustrated, and which stiffening reenforcement may be used expansibly or rigidly, it depending entirely upon the relative arrangement of the stiffeners or reenforcements.
It is to be understood that the particulars herein given are in no way limitative and c that, while still keeping within the scope of the invention, any desired modifications of details anddesired proportions may be made in the apparatus according to circumstances.
The invention comprises further features and combination of parts, as will be herein- 6- after set forth, "shown in the drawings and i 5 I claimed.-

Fig. 18 is a view in perspective of a wall section showing the fabrication of metal plates and illustrating how the stiffener-s 3, 10 and 11 are capable of accordion yielding action,-to cause the stiffeners 10 and 11 to curve slightly as in full lines during such action with pressure in the direction of the arrow a, and illustrating in dotted lines the normal shape of the stiffeners 10 and 11. Fig. 19 is a rear view of such wall section, showing where the accordion walls of the stiffeners 10 and 11 are cut away at 7.
Fig. 20 is a view in perspective showing two wall sections fastened together, with the stiffeners 10and 11 of one section. at right angles to similar stiffeners of the other section.
Referring to the drawings, preferably Figures 1 to 8 inclusive 1 designates the wall section as a-whole, which comprises a plurality of metal plates 2 or metal plate panels, which are provided with stifi'eners 3 with accordion yielding walls, which are expansible or yieldable-so as to withstand internal tions or stiffeners are to be formed in the.
plates or strips by any suitable means, preferably'such as thatembodied in the'previously mentioned patents.
The metal strips which include the stiffeners or reenforcements 9, 10 and 11 have their edge portions welded at 12 to the plates 2, as in Figures 1 to 7 inclusive, or are riveted as shown at 13 in Figures 10 to 12 inclusive.
Obviously the ends of thestifi'eners or reenforcements 3 are welded as at 14 to the stifi'eners or reenforcements 9, '10 and 11, thereby permitting the wall sectionsto expand and contract in directions at right angles to each other.
It is well known that there is on the market a metal product, known commercially as corrugated sheet metal, therefore it is not the aim to claim the same in such terms as would broadly include corrugations in close succession, or commercially known sheet metal. The present form of wall sections are to .be
constructed of relatively thick metal plates,
with the stiifeners, reenforcements or corrugations with accordion yielding walls and arranged at infrequent intervals in certain of the plates, whereas in connecting strip metal plates or"sub-panels the stifi'eners or corrugations are single, or several formed in succession. The stiifeners which are in succession may be at infrequent intervals. However the metal plate 6 has a single stiffener or -corrugation, but of a larger size than those formed in the connecting strips 7 and 8. In fact the less stifl'eners or corrugations, for instance one to be made in the plates 6 the larger they are to be constructed, and those connectingplates which have successive stiffeners or corrugations are to be used to form the sidewalls of acoal bunker, box, room or the like, whereas they wall sections including connecting plates 6,
each with a single corrugation are used for forming thecornersor for connecting wall sections at obtuse angles, or may be used in the side walls of a coal bunker, to constitute the main expansible reenforcement or stifl' choredat the top and bottom, and upon this corrugation the safety of the whole structure may depend.
V In Figures 8 and 13 the wall sections are arranged and connected at obtuse. angles,-
there being insert pieces 15 welded or otherwise secured in the adjoining ends of the corrugations or stiifeners, whereas in Figure 14 arelatively large expansi-ble reenforcement or corrugation stilfeningmember 16 is used to connect the wall sections, enabling the wall sections to expand'and contract, due to any internal or external pressure upon the wall." z
By the construction inv Figures 8, 13 and 14, the plates are deflectedlto arrange walls on anobtuse angle, and to provide a joined structure which is symmetrical and shapely,
and at the same time to insure a closed and secure joint. r a
In Figures 15 and 16 the metal sheets or plates are fabricated in a different manner to those illustrated in the other figures. In fact the plates or-sheets are joined by what may be known as a split indentation 17,
'which will permit the united plates to ex- .pand, yield or contract. In other words the edge portions of the plates are disposed at angles to the plane of the plates, .and riveted or welded together as shown at 18 and 18 Figures 15 and 16.
As previously set forth, and shown in Figure 17 the stiffeners or reenforcements in the form of corrugations are formed from the plates themselves, enabling the plates to contract and. expand.
Though Figure 1 illustrates a series of coal bunkers of a vessel or ship made up of fabricated paneied wall sections, it is ob-' vious'that any form of'compartment may be constructed, wherein there is internal or external pressure, or both, either caused by temperature conditions, or by some mechane ical force. In fact the application of the ,wall sections is not to be limited to any partic-ula-r form or structures. Coal bunkers on railroad cars may be built up by .means of the wall sections, or ice bunkers may be constructed.
\Vhile Figure 2 discloses an enlargement of a coal bunker of the character shown in Figure 1, it is obvious that the construction in Figure 2 may be used to constitute a compartment of any character. However in this figure certain of the connecting plates are disclosed, for'instance plates such as 6 and 7 having the-V-shaped corrugations. The plates 6 are corners, while the plates 7- are intermediate corners. the wall sections in this figure are built up,
so as to yield, expand and'contractin' eitherorboth directions. In fact the flanges and termediate plates or the corner plates where the transverse corrugations 3 are welded to the plates (Sand 7, are cutaway, enabling the walls of the .compartmentto yield or expand and contract ineither or both directernal pressure.
It will-be noted that i .those parts .of the corrugations of the ing sure.
In Figure 8 the wall sections are placed at an obtuse angle, showing inserts connecting the wall sections, the inserts being welded or otherwise connected, to permit the wall sections to yield or expand and contract. It is obvious-that these wall sections may be disposed at right angles as shown in Figure l 9, or at any other angle.
As previously stated the flanges and those parts ofthe plates,6, 7 and 8 to which the ends of the'trans'verse corrugations or stiffeners 3 are connected by welding or otherwise are cut away, as clearly shown in Figures 7 and 8, enabling the wall sections to yield, expand and contract in either or both directions.
Though it is essential to construct the wall sections to expand in either or both directions, it is also obvious that the flanges and those parts of the stiifeners or corrugations of the plates 6, 7 and 8 to which the ends of the transverse corrugations are connected may remain intact, thereby reenforcing the wallsection against expansion and contraction in one direction, whereas the I wall section is allowed to expand andcontract in the other direction at right angles thereto, for instance as shown in Figure 12. While the wall section is reenforced against expansion and contraction in one direction bythe plates 6, 7 and 8, it is to be noted that these plates may be made to permit expansion and contraction in the direction of the plates, even though they are riveted.
It is also obvious that while the drawings show the Wall sections disposed whereby the plates 6, 7 and 8 are arranged vertically, it is clear that the wall sections may be disposed in horizontal directions, or arranged so that the plates 6, 7 and 8 may extend at right angles to certain of the other wall sections, or'at right angles to certain other plates 6, 7 and 8, so as to reinforce a coinpartment or coal bunker wall to a greater degree, than when the wall is made up of wall sections capable of expanding and contracting in either or both directions. is particularly true, if certain of the yieldable stiffeners of the wall sections are not cut away, at the point where the ends of the transverse corrugations 3 are welded to the yieldable stifl'eners.
. It is also to be observed that though the wall section maybe disposed so that its stiffeners may extend at right angles to other stifieners, the entire wall may be al- -lowed to expand and contract in either or both directions, provided the corrugations of the plates 6, 7 and 8 are cut away where the transverse corrugations are welded thereto.
Where great rigidity is required a stifiening member may be introduced at the corners, instead of bringing the edges of the paneled plates or sheets together, and as previously stated the panels or metal plates themselves may be formed into or'provided with stiffening ,nie mbers, as shown clearly in Figure 17-.
' From the foregoing it is obvious that a wall may be constructed so that it may expand in one direction, and reenforced 1n the other direction, and vice versa, or reenforced in both directions, or made in order to expand and contract in both directions, as a result of internal or external pressure, whether caused by temperature conditions or by some mechanical force. It is obvious that walls of different dimensions may be constructed, and furthermore the depth of the main corrugation 6 depends entirely upon the height as well as the width of the wall to be stiffened. In fact the reenforcement of the wall also depends upon the force of pressure, whether or not it is internal or external, and at what point or location the pressure occurs. The construction and reenforcement of a wall ncluding the present form of expansible stiffener also depends on whether or not the pressure is-created by heat or cold, or by some mechanical means or force. By referring to Fig. 18, it will be evident why the structure in the plate metal walls maintains an absolute plane surface, that is not warping irregularly under heat, and at the same time provides sufiicient stifiness to withstand the pressure in a direction at right angles to the plane of the wall and yet allow; the walls of the stitfeners to have yielding accordion action and permit a wall to expand and contract in various directions with the plane of the wall, when sub1ected interiorly to heat, say 500 Fah., the sections illustrated in Figs. 18 and 19, preferably the former, may be taken from any wall having an extent of ten times the portion illustrated. The actual distance between the points A-A and BB on such figures, especially Fig. 18, may be taken as 36 inches. The expansion per degree Fah. of such an area may be taken as .0000128 of an inch each inch per degree. In such case, the increase of distance between A to A for 500 iiicreaseof temperaturewould be .2304. As this increase for the distance A to A (:for
-36 inches) may be taken from a runnlng area of ten times that. distance, the expansion will be 2.304 inches. The expansion invariably tends to close the angle contained within the stifiener or indentation, and this 19. The ease with which the sides of the indentation or stiffener approach each other increases with the increase due to expansion of length of the flat surface between V the indentations. The greater the heat, the
more the flat surface expands and the more flexible the indentation or stiffener becomes depth of the fiat portion produces. .It is 11 of the metalstrip, plate 8. v rang'ement, together with the cut-away porevidentthat the junction between the" crossing indentations .partakes proportionately of the general movement of the sides of the indentations towards one another.
With regard to coal bunkers, as in Figs. 1 and 2, it is obvious that a vessel is subjected to considerable vibration due to the throb or pulsation of the engine and its attendant cooperating elements, in view of which the coal would compact thereby causing internal strain or pressure of the walls of the bunker; and sincethe stiffe'ners have accordion yielding opposed walls, the side Walls of the coal bunker will give or yield and thereby permit expansion and contraction in various directions.
Referring to Fig. 7, which is a sectional- View on line 7-7 of Fig; 5, it is to be noted that where the stiifeners 3 are electrically Welded to the accordion walls of the stiffeners 10 and 11 of the metal strip plates 7, 8, and 9, the metal of such accordion walls is cut away, as shown more clearly at 7 in Fig. 19. Also, referring to Fig. 6, it will be observed that the stitfeners extend to the peak" of the accordion walls-of the slt illfeners 1s. ar-
tions of such accordion walls, permit the plate metal panels to expand yieldably and then yieldably return to normal shape, due
to the, internal pressure derived from the fluctuation of intense temperature or heat on the interior of a structure having such walls. The stilfeners of the metal strip plates will also have accordion-yielding action which, .with the accordion yielding action of the stifl'eners 3, enable the wall construction'in Figs. 2, 5, 18, 19, 20 and 21 to expand and contract in various directions with the plane of the wall construction.
This yieldable expansion and the return to normal condition takes place due to internal pressure caused by enormous compacting, or compacting heavyweight against the interior surface of the wall construction.
1 In Fig. 18, the stiflfeners of the metal strip .plates arein the act of an accordion yield- ,ofstilfeners-3. During such accordion action, the bases of the triangles of the stiffeners of the metal strip plates widen. In other words, as the accordion walls of the stilfeners 3 are so functioning, the bases of the triangles of the stifieners 3 are widened, while the stifi'eners 10' and 11 of the metal strip plates assume a curvature, clear- 1y shown in Fig. ,182' The wall constructions in Figs. 18 and 20 may be turned around so that the stilfeners 3 may assume Vertical positions in which case a Wall construction of great extent maybe so used and installed. From the foregoing, in connec tion with Figures 2, 5, 18;"and 19, it is clear, the wall construction or wall'sections may expand and contract in various directions through the plane of the Wall construction.
