Definitions
- This invention relates to structural members for use primarily in the construction of houses and other build ⁇ ings.
- a typical building such as a house, includes a variety of different structural or framing members.
- Examples are wall studs, floor and ceiling joists, roof rafters, partition wall studs, etc. These members have traditionally been made of wood, although in recent years sheet metal studs have found increasing use.
- a composite structural member constructed in accor ⁇ dance with this invention comprises a body part and mul- tiple rigid strips which are attached to and separated by the body part .
- the body part is formed by a core having substantially flat parallel sides and opposed edges, and the opposed edges are covered by the rigid strips.
- the core is made of gypsum and the strips are made of sheet metal. Backing sheets of paper may be secured to the sides.

- a wall 30 which may be a partition wall, for example, of a house or other type of building.
- the wall 30 includes a plurality of vertically extending composite studs 31 constructed in accordance with the present in ⁇ vention which are spaced apart in the horizontal direc ⁇ tion.
- the studs 31 are fastened at their lower ends through a C-shaped metal floor chan- nel 32 and are fastened at their upper ends through a C- shaped metal ceiling channel 33.
- the two boards 34 and 35 are gypsum wall- boards .
- the stud 31 comprises a main body 41 and two rigid strips 42 and 43.
- the main body 41 in ⁇ cludes a core 44 formed, for example, of gypsum and cover or backing sheets 45 and 46 secured to the two sides of the core 44.
- the main body 41 includes two edges 47 which are covered by the rigid edge strips 42 and 43.
- the two rigid strips 42 and 43 are preferably made of sheet metal, and in the embodiment of the invention il ⁇ lustrated in Figs. 1-4, the two strips 42 and 43 cover the edges 47 and each includes flanges 48 which fold or extend over the backing sheets 45 and 46.
- the strips 42 and 43 are firmly secured to the main body 41, and the boards 34 and 35 are secured to the members 31 by screw fasteners 49.
- the fasteners 49 extend through the boards 34 and 35 and self-thread through the rigid strips 42 and 43 and firmly secure the boards 34 and 35 to the strips. Since the strips are, in turn, secured to the main body 41, the boards 34 and 35 are separated by and secured to the studs 31.
- the core 44 is made of gypsum and its sides are covered by backing sheets 45 and 46 of the type normally used to cover ordi- nary gypsum wallboard.
- These dimen ⁇ sions are the most common size for conventional wall studs.
- the strips 42 and 43 are made of sheet metal preferably having a minimum thickness of 0.0179 inch, and the flanges 48 have a length of approximately 1/4".
- the stud 31 constructed in accordance with this invention has a number of advantages. Its cost may be substantially less than the cost of a comparable size wood or metal stud.
- the main body 41 is relatively fire- resistant and does not conduct head readily between the two boards 34 and 35.
- the metal strips 42 and 43 cover and protect the end surfaces of the core 44 and they also form members to which screw fasteners may be firmly se ⁇ cured.
- the studs may have the size and feel of wood studs and may be handled with essentially the same con ⁇ struction techniques as wood studs.
- the stud construction shown in Figs. 3 and 4 may include a main body formed by a single sheet of gypsum shaft liner, which is normally approximately 1" in thick ⁇ ness. With the addition of the flanges 48, such a stud will have an overall thickness of approximately 1-1/32". Instead, the stud shown in Figs. 3 and 4 may be formed of a single core having a standard stud size of a thickness of 1-1/4" and a width of 3-5/8".
- Fig. 5 illustrates a preferred construction wherein the main body of a stud 51 is formed by two layers 52 and 53 of 5/8" gypsum board. Each of the layers 52 and 53 is covered on both sides by backing sheets 54, and the edges are covered by rigid strips 55 which extend across both layers. The adjoining backing sheets 54 of the two lay ⁇ ers 52 and 53 may be fastened together by an adhesive, and the strips 55 may be secured to the two layers 52 and 53 by an adhesive.
- Figs. 6 through 13 illustrate different methods of securing the rigid strips to the main body.
- the main body may be formed by a single layer of core material and backing sheets as shown in Fig. 4. or by two layers as illustrated in Fig. 5.
- a structural member 60 which includes a main body 61 and two edge strips 62.
- Each of the edge strips 62 includes flanges 63 as previously described, and the flanges 63 are secured to the main body 61 by crimps or indentations 64 at spaced locations along the length of the structural member 60.
- the crimps or indentations 64 are provided in place of or in addition to an adhesive between the strips and the core and the backing sheets of the main body 61.
- Fig. 7 illustrates a structural member including a main core 66 and edge strips 67 (only one shown) , wherein flanges 68 of the edge strips 67 are secured to the main body 66 by staking as indicated by the numeral 69 at spaced locations along the length of the structural mem ⁇ ber.
- Fig. 8 illustrates a structural member 71 similar to the member 60 shown in Fig. 6. However, it is formed by two layers 72 and 73 instead of a single layer, and by rigid edge strips 74.
- the edge strips 74 are secured to the two layers 72 and 73 by crimps 75 similar to the structure shown in Fig. 6.
- the two layers 72 and 73 are preferably glued together and they may be fastened by an adhesive to the edge strips 74.
- Fig. 9 shows a structural member 77 including a main body 78 and two edge strips 79.
- Each edge strip 79 in- eludes two flanges 80 which are pressed toward each other and into the sides 81 of the main body 78, thereby secur ⁇ ing the edge strips to the main body.
- edge strips 82 are secured to a main body 83.
- Each of the edge strips 82 has two flanges 84 and each of the flanges has preformed prongs 85 formed in them at spaced locations.
- the prongs 85 may be precut by a punching operation.
- to assemble an edge strip 82 with the main body 83 the center portion of an edge strip 82 is positioned against an edge of the main body and then the flanges 84 are bent downwardly and inwardly to drive the prongs 85 into the main body 83 and secure the edge strip to the main body 83.
- the main body 88 has edge strips 89 attached to it.
- Each of the edge strips 89 includes flanges 90 and the flanges have edge portions which are bent inwardly to form flange lips 91.
- the main body 88 has grooves 92 formed along the sides 93 adjacent the edges of the main body, and the flanges 90 are bent inwardly as best shown in Fig. 13 to cause the flange lips 91 to fold into the grooves 92.
- the lips 91 extend at substantially a right angle to the adjacent portions of the flanges 90 and the grooves 92 are shaped to engage the lips 91.
- each of the grooves 92 has a surface 94 which is at a right angle to the side 93 and is engaged by the lip 91, and another surface 95 which is sloped or angled to provide clearance for the lip 91 when the flange 90 is bent inwardly.
- Figs. 14 and 15 illustrate a construction wherein edge strips are secured to a main body by covering it with a sheet of backing material .
- a flat strip 104 of rigid material is positioned against the edge 105 of the main body 101, and the width of the strip 104 is substantially equal to the overall width of the main body 101.
- a cover strip 106 is positioned over the strip 104, and the strip 106 is sufficiently wide that it folds over the edges of the strip 104 and onto the outer sides of the layers 102.
- the folded over portions 107 are securely fastened by an adhesive to the sheets 103 of backing material, thereby securing the edge strip 104 to the main body 101.
- edge strips 104 and strips 106 are provided along each edge of the main body 101.
- the cover strips 106 may be made of back ⁇ ing paper or other sheet material .
- Fig. 16 illustrates a structural member including a main body 111 and edge strips 112 secured to opposed edges of the main body.
- two layers 112 of board are secured together to form the main body.
- Each edge strip 112 includes a downwardly bent flange 114 and layers 115 of adhesive secure the flanges 114 to the outer backing sheets of the layers 113.
- the center portion of each edge strip (that is the portion of the edge strip between the two flanges 114) may not be secured to the main body 111.
- the edge strips are secured to one or more layers of core material, after the core material has been formed. Normally the layers have been cut or formed into long strips.
- the core material of the main body may be extruded or cast in place and secured to the backing sheets and to the edge strips before it has set.
- a structural member 120 is formed by a core 121, two backing sheets 122 and
- the core 121 is made, for example, from gypsum and may be cast in place or extruded in the shape shown in Fig. 17.
- the two rigid strips 124 are positioned against the edge surfaces 126 and then the backing sheet 122 is folded over one side 127 of the core, over the two rigid strips 124, and then over at least part of the other side 128 of the core.
- the second backing sheet 123 is then positioned against the side 128 and overlies the folded edge por ⁇ tions of the sheet 122.
- the backing sheet 122 may be sufficiently wide that it completely envelopes the core 121, thereby eliminating the need for the second sheet 123.
- the rigid edge strips 124 preferably include a plurality of perforations 129 which extend through the strips.
- the perforations 129 permit the slurry, used in forming the core 121, to pass through and engage the backing sheet 122 and attain a better attachment with the backing sheet at the edges of the member.
- Figs. 21 and 22 also show two embodiments where the backing sheets and the end strips are secured to the core and backing sheets before the core slurry has finally set.
- a core 135 of, for example, gypsum slurry is formed and a backing sheet 136 is folded around one side, the edges and over a portion of the opposite side.
- a second backing sheet 137 is then applied to the other side of the core.
- the backing sheets are, of course, similar to those shown in Fig. 17-19.
- Extending along the edges of the core are two rigid edge strips 141 which have flanges 142.
- the flanges 142 angle inwardly and they extend into indentations 143 in the core 135 and the backing sheet 136, thereby forming a firm connection between the edge strips 141 and the core 135.
- the flang- es 142 may be initially angled inwardly as shown in Fig. 21 before the core slurry is poured into the backing paper, or the flanges may be bent inwardly and the inden ⁇ tations 143 formed after the core slurry has been poured.
- a single sheet may be provided, having a width sufficiently wide that the edges overlap and form an envelope around the core.
- Fig. 22 shows a structural member similar to that shown in Fig. 21 and includes a core 146 having backing sheets 147 along opposite sides, and edge strips 148 along the opposed edges.
- the structural member shown in Fig. 22 is, of course, similar to the member shown in Fig. 21 except that the backing sheets do not extend across the edges of the core and underneath the rigid strips.
- Figs. 23, 24 and 25 illustrate additional structural members incorporating the present invention.
- a cutaway view of a house 153 mounted on a foundation 154 is illustrated.
- the house includes load carrying floor joists 156, ceiling joists 157, wall studs 158, roof rafters 159, and studs 160 forming an interior partition. All of the members 156-160 may be formed by composite structural members in accordance with the pres ⁇ ent invention.
- the floor and ceiling joists and the roof rafters 159 preferably have increased cross-sectional dimensions sufficient to withstand the structural forces imposed on them.
- Fig. 24 illustrates a truss 166 which may be partic ⁇ ularly useful in a manufactured home, for example.
- the truss 166 is formed by a single panel forming a main body 167 shown in Fig. 3.
- the peripheral edges of the main body 167 have rigid edge strips 168 secured to them, so that other parts of the structure may be secured by screw fasteners to the truss 166.
- the main body 167 as illustrated is imperforate, it may include openings for utilities such as conduits and wires.
- the wall studs and other structural members de- scribed herein may have openings preformed through the main body to receive wires, etc.
- Fig. 25 illustrates a section of a rather large building including vertical columns 171 and horizontal floor and ceiling slabs 172 and 173.
- Curtain walls 174 are mounted at the exterior of the building.
- Reference numerals 175 and 176 indicate partition walls including wall studs 177 constructed in accordance with the present invention. Since the walls 175 and 176 function to di- vide or separate the interior space on a floor of the building and are not load bearing, the core of the struc ⁇ tural members may be formed of a relatively lightweight material such as lightweight gypsum.
- Load bearing refers to a load parallel to the long length of a stud; such a stud will normally bear a transverse load, that is, a load which is substantially perpendicular to the long length of the stud.
- the curtain wall 174 is also not load bearing and may be structured in accordance with this invention.
- the main body of the structural members includes a core at least partially covered by at least one backing sheet.
- Fig. 26 illustrates an embodiment of the inven ⁇ tion wherein the core 181 forming the main body has suf- ficient structural integrity that exterior backing sheets are not needed.
- the core 181 may be made of a gypsum-cement composition, or it may be made of gypsum with a fiber filler or binder.
- the number 182 indicates the strands of a fiber such as the paper fiber normally used in the above described backing sheets. In such an instance, backing sheets are included in the main body but are incorporated in the core materi ⁇ al.
- the core 181 is secured to edge strips 183 made, for example, of sheet metal.
- the strips 183 include inwardly angled flanges 184.
- the member shown in Fig. 26 is pref ⁇ erably constructed by casting the core 181 in place be ⁇ tween the flanges 184.
- Structural members incorporating the present inven- tion may have cores made from a variety of different materials, such as gypsum, gypsum-cement compositions. For example, standard weight or lightweight gypsum, or recycled gypsum, or a moisture-resistant gypsum core, may be used. Various fillers, such as wood chips and/or volcanic material, may also be included.
- the backing sheets may also be made of a variety of different materi- als, so long as the material has good shear resistance, such as paper, or paper treated for moisture resistance, sheets of woven fiber, etc.
- the edge strips do not nec ⁇ essarily have to be made of metal but could, for example, be made of a strong plastic, so long as they are able to facilitate the attachment of fasteners to the structural member.
- a structural member in accordance with this inven- tion has numerous advantages.
- the structural members have good resistance to heat or cold transfer. While the edge strips may be made of metal which are good heat conductors, the strips on opposite sides of a member are separated by a low heat conducting core material, and therefore reduced heat or cold is transferred from one side to another.
- the core acts as a heat sink (it absorbs heat) , and heat drives moisture out of a core material such as gypsum and thus dissipates the heat. Screw fasteners used to secure boards 34 and 35 to the studs are buried in the core materials of the boards and the studs and thus are pro ⁇ tected against overheating.
- the structural member is made sufficiently strong and rigid by the combination of the core material, the backing sheets and the rigid strips .
- the core serves to hold the backing sheets in straight parallel planes, and the backing sheets give the member strength and stiff- ness.
- the edge strips add further rigidity and strength.
- the backing sheets provide needed strength against a transverse force (that is, a force perpendicular to the plane of the backing sheet) .
- the core may be made of a less costly material, such as lightweight gypsum, recycled gypsum, or a composition including inexpensive fillers.
- the structural member is relatively stiff and may be secured using screw fasteners, it may be handled similarly to wood products.
