Definitions

  • the invention relates to a floor system having steel joists and rim members supporting the joists, the joists and rim members being formed with openings, and having edge reinforcements formed around the openings.
  • the openings in the joists are formed with linear reinforcement channel formations along opposite sides of the openings, which are formed with bends at respective first and second angles with respect to the plane of the joist.
  • Metal joists have been proposed formed with openings, usually generally triangular or trapezoidal openings, in the web, while the two edges were formed with bends, as before. These openings were positioned so as to define diagonal struts extending across the joists. In this way it was hoped to achieve strength while reducing weight and obstruction.
  • the openings in the metal joists were of these specialized generally triangular or trapezoidal shapes, the services, in many cases conduits of substantial diameter, could not fit through the openings. It was not possible for the builder to cut away any of the diagonal struts to provide larger openings for services, since this would drastically reduce the strength of the joists. Another problem arose in cutting these joists to length.
  • the openings were arranged in pairs with one triangle facing one way and the next triangle facing the opposite way. Cutting such joists to length requires that all of the openings of a particular orientation, in all of the adjacent joists in a floor, shall line up. This was required to facilitate passing of services through the joists. However, due to the alternating orientation of the openings, this requirement resulted in cutting off end portions of joists equal in length to the space occupied by two of the openings, in many cases.
  • the shape of the openings is symmetrical and identical, making it possible to align the joists in pairs back to back to form stronger composite joists while still maintaining the full size of the openings through the joists for passing services.
  • the invention comprises steel joist members, for use in floor system, and having a web defining side edges and an axis, a edge flange on at least one side edge of the web, identical symmetrical openings formed through said web at spaced intervals therealong, of predetermined size and profile, with rounded ends and linear sides parallel to one another, side portions of said web displaced from said opening remaining attached integrally to said web along opposite linear sides of the opening, a first bend formed in each, said side portion, a second bend formed in each said side portion parallel to and spaced from said first bend, said first and second bends being formed along axes parallel to said web axis.
  • the invention further seeks to provide a steel joist member as described including depressions formed in said web at spaced intervals, and openings formed in said depressions to increase strength and to provide some reduction in heat transfer.
  • the invention further seeks to provide a steel joist member as described wherein said displaced side portions define respective channel shapes extending along axes parallel to said web axis.
  • the invention further seeks to provide a steel joist member as described wherein said openings are of a shape defining opposite parallel linear side edges, and arcuate end edges, said side portions of said web being integral with said linear side edges, and continuous edge flanges formed all around said openings.
  • the invention also provides a composite joist member formed of two steel joists as described being attached back to back to one another to form a composite joist member.
  • a composite joist member formed of two steel joists as described being attached back to back to one another to form a composite joist member.
  • composite joists can be made simply by placing two joists back to back with their openings in registration with one another. Such composite joists have great strength, while still permitting the passing of services.
  • the invention also provides a rim member for attachment on a structure around a floor, and supports on said rim member for supporting opposite ends of each steel joist member.
  • the rim member may also incorporate fastening tabs for fastening to each steel joist member.
  • the rim member may also incorporate embedment formations, and also joist end abutments.
  • the invention also provides a method of making a steel joist member having a web and side edges, and a flange along at least one said side edge, and openings through said web, said method comprising the steps of, forming openings having opposed linear parallel sides and arcuate ends in said web at spaced intervals therealong, leaving side portions of metal attached to said web along each of said opposed linear sides, forming said edge flange along said at least one side edge of said .web, and, forming said side portions out of the plane of said web by bending each said side portion along a first bend line and then along a second bend line spaced from and parallel to said first bend line.
  • the invention also provides a method of forming a floor joist system, using rim members and steel joist members described above.

  • the invention provides a floor or roofing system using sheet metal joists, having improved acoustical performance to reduce transmission of sounds from one floor to the next.
  • the invention also provides sheet metal joists suitable for use in reinforcement of slab concrete panel floors or roofs.
  • the invention also provides composite H shaped or I shaped joist members formed by joining two joist lengths together back to back, and a method of making such a joist member, and a method of forming a floor.
  • floor is used to describe a level structure used in construction, which may function either as a floor for supporting persons and objects within a structure, or to a roof for enclosing a structure. When used as a roof, such a structure will usually have a slope, whereas when used as a floor it will be level. The invention is equally applicable to either function.
  • the invention is there illustrated in the form of a floor (10).
  • the floor (10) made up of composite sheet metal joist members (12), and rim members (14).
  • the rim members (14) are supported on the upper edge of a wall, not shown, or a basement or other structure.
  • the joist members (12) span the space surrounded by the rim members (14), and the joist members (12 ) are supported at their ends on the rim members (14)
  • the composite joist members (12) in this embodiment are composites made up of two identical joists (20), placed back to back.
  • each joist (20) is formed of sheet metal, in this case steel.
  • Each joist (20) has a web (22) which is essentially planar, and an edge flange (24) along the lower side edge of the web (22). Edge flange (24) is formed by bending the web at right angles. A lip (26) is formed on the edge flange (24) again at right angles.
  • openings (28) are formed by punching out a portion of the sheet metal, and by displacing but not removing other portions of sheet metal as will become apparent below.
  • the openings (28) are formed in a generally oval shape elongated along the length of the joist (20).
  • the openings are identical and symmetrical for reason to be described.
  • Each opening (28) has opposite ends (30) located along the central axis of the web (22) with a semi-circular or arcuate profile. Between the ends (30) along opposite sides, the openings (28) are formed with elongated linear parallel sides as at (32). , Elongated transverse ribs (34) may be formed if desired, at the ends of the joists,
  • edge flange (36) formed at right angles to the web (22).
  • bracing lips (38) formed, extending integrally from the edge flanges (36). Lips (38) is formed by portions of the web (22) which have been partly punched out and displaced, but which remain joined as part of the edge flanges (36), along such linear sides of the opening (28). Bracing lips (38) are formed at a right angle bend (40) parallel to but spaced from the plane of the web (22).
  • the two bracing lips (38) form short channel shape reinforcements, extending from the edge flanges (36), along the two linear sides (32) of the opening (28).
  • lips (38) greatly reinforce the joist (20) along the length of the two linear sides (32) of opening (28).
  • This feature permits the openings (28) to be formed with relatively large dimensions, so that a conduit, not shown, can extend through opening (28) and is limited only by the transverse dimension of the opening transversely across the web (22). This is a great improvement over joists having triangular openings.
  • a junction flange (42) is formed along the upper side of the web (22), for reasons described below.
  • the shape and placement of the openings (28) defines struts (44) extending transversely across the web (22). Such struts reduce the transfer of sounds across the joist.
  • Joists (20) are further formed with depressions (46) at opposite ends of each strut (44) where the strut flares out into the web (22). Centered in such depressions (46) there are punched out openings (48), which in this case are circular, although they could be other shapes.
  • the openings (48) remove metal and this provides a better barrier to conduction of sound across the joist and improve its acoustical performance.
  • This embodiment of joist is particularly advantageous. It has great strength due to the retention of a considerable amount of the metal displaced by blanking the openings (28).
  • Figs 1 to 6 illustrate another feature of joist (20) for embedment in a concrete slab.
  • junction flanges (42) are formed with embedment edge flanges (50) which are bent out of the plane of the web by about 45 degrees. The angle can vary somewhat for various applications. Flanges (50) are bent outwardly, and are formed with a series of openings or ports (52) for concrete flow.
  • a return lip (54) is formed along flange (50) for embedment in concrete.
  • This embodiment provides a joist of great strength providing reinforcement for a concrete floor slab or panel.
  • the flanges (50) being partially embedded in concrete will provide maximum security of adhesion between the joists and the concrete.
  • This joist may enable the use of a reduction in thickness of sheet metal. It is anticipated that a reduction of at least one gauge and probably two gauges can be achieved while still providing adequate support to a concrete floor slab or panel.
  • Fig 9 shows a further form of joist (100) having features which make it suitable for supporting floors made of other panel materials, such as plywood or the like.
  • Joist (100) has a web (102) and identical side flanges (104) and (106) along either side of the web.
  • Lower and upper edge flanges (104) and (106) are identical and are bent at a right angle to the plane of the web.
  • Integral edge lips (108) extend from flanges (104) and (106) parallel to the plane of the web.
  • Ribs (110) are formed as before transversely of the joists (100)
  • Openings (112) are formed through web (102) as before, being of generally elongated oval shape in the Fig 1 embodiment.
  • Edge rims or flanges (114) are formed therearound as before.
  • Linear side edges (116) and (118) of opening (112) are reinforced by bracing lips (120) of sheet metal, extending integrally from web (102), thus retaining more of the metal displaced by forming the opening (112) and employing it to improve the joist, rather than discarding it as waste.
  • Lips (120) are folded into right angular channels extending along each linear side of opening (112), to provide greater strength. More metal is retained in the joist, which both increases its strength or, in the alternative, permits a reduction in gauge. Depressions, (122) with openings (124) which may be circular or other shapes are formed in the web, as described above to aid in reducing heat losses.
  • two such joists (20) or (100) are juxtaposed as shown in Fig 1 and 9, in back to back relation. They may be secured together, if desired, by example spot welds or the like (not shown) to form a composite joist member.
  • Manufacture of the joists (20) or (100) can proceed by first forming the openings (112) and rim flanges (114) in a suitable press. This can be a flying die press, but it is advantageous to use a rotary press of the type which has two rotary die support rolls, and dies on the support rolls, in which the two support rolls rotate bringing the dies together and apart as the sheet metal moves between them.
  • the semi-formed sheet metal is then passed through a series of roller die stands, such as are known per se and require no description.
  • the roller dies on the die stands will progressively form the edge flanges (24) or (104,106) and the bracing lips (38) or (120) on either side of the openings. Cutting to length may be performed upstream of the rotary press where the strip sheet is still flat and unformed. In this way each piece of sheet metal passing through the various punching and forming and roll forming sequences is already precut to the exact length required for the finished joist. It also possible to cut the joists to length downstream of the roller dies, depending on the design of the equipment.
  • a rim member (14) is provided, as shown in more detail in Fig 6 to 9.
  • the rim member (14) has a web (130) and a top flange (132) extending at right angles.
  • Flange (132) is intended to lie on top of a wall or basement structure.
  • Flange (132) may have an upstanding edge wall (134) (Fig. 11 ), or a downwardly bent edge wall (136) (Fig. 10) turned down to lock on to the outside of a wall.
  • a support flange (138) extends at right angles, to support the ends of the composite joist members (12).
  • tabs (140) are struck out of web (130) and extend in parallel spaced relation over support flange (138). In the embodiment shown the tabs (140) are located in the same plane as the flange (132). In this way the upper horizontal surfaces of junction flanges (42) of the joist members (12) will lie coplanar with the flange (132).
  • the embedment edges (50) of the joist members will extend above such a plane, and this is intended so that a concrete floor slab may be poured which extends over flanges (132) of rim member (14).
  • a short portion of the embedment flange will be removed at the ends of the joist members (12).
  • the junction flanges (42) will fit beneath the tabs (140) and secured thereto by fasteners.
  • Fasteners will also be used to secure the edge flange (24) to the support flange (138) of the rim member (14).
  • the flange (132) of the rim member (14) is formed with embedment loops (142) struck out of the flange. The poured concrete will flow around such loops (142) and will thus secure the rim member (14) in position.
  • the flange (132) of the rim member (14) is formed flat, without any such loops (Fig. 12). This enables such a panel floor to be laid flat on the upper flanges (106) of joists (100), and then to lie flat on the flanges (132) of the rim member (14). Since, in this case the upper flange (106) is planar, it will fit beneath the tabs (140) without requiring the removal of any portion. It will be understood that in many cases there may be only two such rim members (14), parallel and spaced apart on opposite walls for supporting joist members (12) spanning the area. For additional stiffness, if desired, abutments (144) may be formed in the web (130). These abutments are spaced apart so as to engage the opposite sides of the composite joist members, at each end. •
  • the webs (130) are also formed with generally oval shaped openings (146) similar to the joists, and edge flanges (140) and lips (15) are formed therearound as before.
  • Vertical ribs (152) are formed in web (130) for adding stiffness.
  • rim members (14) there may be four such rim members (14), or even more, depending on the area to be enclosed by a floor. Intermediate rim members (14) supported above a floor by any suitable means may be required to span a greater area, of the cover in a space of a special shape in plan.
  • FIG. 10 is a perspective of a further embodiment of floor system using composite joist members illustrating another embodiment of the invention, in which the rim member is modified from Fig 1. In this case, the edge wall (136) is shown turned down.
  • Figure 11 is a perspective of a further embodiment of floor system illustrating another embodiment of the invention, for supporting a panel floor typically of plywood, with the composite joist members modified to remove the embedment edges.
  • the composite joist members are the same as in Fig 1 but the embedment edges are removed and replaced by a flange similar to lower flange (24). This enables plywood or other panel to be laid flat on the composite joist members.
  • the rim member is also modified to remove the embedment loops and present a flat upper surface.

  • the joist members have the same features as the joist members (20) of Fig 1, but are used singly, and not fastened back to back.
  • FIG 15 is a perspective of a further embodiment of floor system using composite joist members illustrating another embodiment of rim member in which the flange (164) is of reduced width compared to Fig 1.
  • the flange (164) is of reduced width compared to Fig 1.

  • a modified form of steel joist member is illustrated in Figures 16 and 17 as (170).
  • the joist member (170) has a web (172) identical generally oval- shaped openings (174) formed there through.
  • Edge flanges (174) are formed around openings (174).
  • Bracing lips (178) are formed along the opposite linear side edges without the openings (174).
  • angled portions (180) are formed.
  • Parallel linear edge flanges (182) are formed along the opposite edges of the web, lying in planes which are parallel to and spaced from one another.
  • the free ends of the edge flanges (182) are folded inwardly at folds (184).
  • Folds (184) interlock with the bracing lips (178) (Fig. 17).
  • This thereby forms a generally triangular form of reinforcement along the joist member (170) at spaced intervals.
  • Recesses with central openings (186) are formed between openings (174) to reduce heat transfer. Additional reinforcement ridges (188) may be formed at locations along the web.
  • Joist member (170) as shown in Figures 16 and 17 may be used to replace the double joist members (12) in many cases.
