Definitions

  • the floor structure In pre-cast concrete wall bearing structures, the floor structure must be placed over the pre-cast concrete wall and have a bearing surface thereon that is perfectly smooth, has a steel plate or grouted tie bar connection, and must be placed before the next level of walls is erected.
  • the resultant structure is very heavy and often has connections that are difficult to conceal or has very labor intensive grouted connections.
  • This invention relates to a new method of constructing structures of all types and heights. It utilizes a metal "Z" or plate along with other metal shapes that permit a floor system to bear outside of the plane of the bearing wall. Means are provided to allow the structural frame to be erected to six or eight stories with un-topped floors. This allows full building enclosure with safe working areas as the building is erected. The installation of pipes, conduits, and ducts may be placed between the floor levels and be fire and acoustically sealed by the cementicious topping placed after erection of the building under controlled conditions. It also relates to methods of controlling disadvantageous shrinkage in wood frame buildings heretofore unknown in the art and allows the use of concrete and steel framed floors that provide acoustic advantages and may be economically and quickly constructed.
  • This invention also teaches a more economical and efficient method for tensioning diagonal tension straps after framed walls are erected.
  • Another object of the present invention is to substantially decrease sound flanking paths over the top of a wall at the floor line and permit fire and acoustic sealing of pipes, ducts, and conduits that penetrate the floor without using additional special materials.
  • a further object is to provide a safe working environment immediately upon erection of bearing walls, enclosure walls, and metal decking before concrete is placed.
  • a still further objective is to allow wood frame buildings to avoid combustible floor construction and achieve a continuous diaphragm of metal decking and cementicious materials.
  • Another object is to permit light steel construction for buildings of any height.
  • An additional purpose is to provide a means of pre- tensioning diagonal tension straps by one person in a very simple and economical way.
  • a structure of panelized light gauge metal, wood frame, or pre-cast concrete walls is erected upon a foundation.
  • Sheathing material may be pre-applied to the light metal or wood framed walls and metal decking installed upon metal plates or "Z" members attached to the tops of the wall panels.
  • Windows, doors, and other opening protective devices may be pre-installed along with insulations and weather proofing to provide an enclosed working environment that allows follow-on trades to work under environmentally controlled and safe conditions. Up to six further levels may then be erected while mechanical trades are working in the level below placing cementicious topping on the metal decking.

  • bottom and top tracks 2 within which the bearings studs are seated.
  • Numeral 3 refers to a fiber cement piece which may have ladder wire reinforcement 4 over the fiber cement piece.
  • Disposed within the bottom tracks 2 is fiber reinforced concrete 5.
  • the fiber reinforced concrete is applied over the composite metal deck 6 which serves as a deck for the upper level and as a ceiling component of the level located directly therebelow.
  • Furring members 7 are optionally provided for the undersurface of the composite metal deck 6 for application of a drywall ceiling finish 8.
  • an acoustic channel 9 is provided on a side of the bearing studs 1 to support gypsum board 10, which serves as a fire protection means.
  • gypsum board 10 Disposed across the top of the bearing stud at the ceiling level is a wall cap 11 having laterally extending legs which help to support the metal deck 6.
  • Acoustic sealant is sprayed on, around and under the wall cap and batts of fiberglass or other suitable material 13 may be placed between the bearing studs on one side and the gypsum board 10 on the opposite side.
  • a screw 14 or other suitable fastener is disposed through the fiber cement piece 3 to secure together the bottom track 2, the fiber cement piece 3 and the wall cap 11.
  • Fiber reinforced concrete is disposed over the fastener in the bottom track 2 to complete the seal and provide a rigid structure.
  • the fiber cement piece is also secured to the composite metal deck using screws 16 or other suitable fasteners.
  • This invention allows stud walls prefabricated in appropriate pieces to be erected by floor and then have a wall cap installed to allow a floor deck to be immediately placed.
  • the deck is screwed from below through the contact flutes and then the wall cap fiber cement piece is screwed into the top of the deck. At this point the deck is usable as a walking surface.
  • the prefabricated stud wall for the next floor may then be screwed down.
  • Diagonal tension straps may be tightened on each floor as soon as the panels i.e. the stud walls are placed, as discussed in further detail hereinbelow. Concrete may be poured after three floors are erected and pipes, conduit, and other through floor services are installed to allow a seal for fire protection of the through floor services and pipes.
  • the height of the building so erected is limited by fire ratings required on the bearing walls and the floors.
  • This system provides a floor with fire ratings without a ceiling finish, superior stopping of acoustic bridging across the tops of the walls and elimination of metal to metal contact. It provides a diaphragm across walls that can transfer much of the horizontal loads for mid-rise buildings.
  • Figure 2 illustrates an alternate design which requires no wall cap, sprayed acoustic sealant or fiber cement board separation piece.
  • This embodiment is similar to the first embodiment in that 21 designates the metal studs which make up the bearing wall, having top and bottom standard tracks 22 placed thereover or thereunder respectively.
  • a metal plate 23 of 12 to 16 gauge material is disposed at the top of a stud wall and extends approximately 1 and 1/4 inch beyond the stud width on each side. The metal plate is thus 6 1/2 inches for a 4 inch stud wall.
  • the metal plate is screwed in place with a self-tapping screw or like fastener at each flute.
  • a metal L member 24 is used to reinforce the top of the flutes in the decking and to close off the ends of the deck to prevent concrete run through.
  • This may be the same gauge as the deck and may be applied with the deck in place or it may be pre-applied. Mastic and/or screws may be used to fasten the metal L member.
  • This structure then includes the metal composite deck 25 which spans between the bearing points.
  • a fiber reinforced concrete slab 26 may be poured after multiple stories of a structure have been erected.
  • the gypsum board wall fire proofing and acoustic treatment and decorative ceiling finish 27 may then be applied.
  • Furring channels 28 from 1/2 inch to 1 1/2 inch are attached to the decking to allowing wiring, conduit and piping rods to be installed.
  • batt installation 29 may be disposed within the wall for its acoustic and thermal properties. This particular embodiment is somewhat faster and less expensive to build and requires fewer parts than the first described embodiment.
  • Figure 3 illustrates a slightly modified version of the wall shown in Figure 2 in which a thicker plate is installed over the top of the walls to allow greater tolerance in deck length. This also allows concrete to seal around the outside of the track 32.
  • the walls are designated by numeral 31.
  • top and bottom steel stud tracks 32 are disposed over or under, respectively, the metal stud bearing walls 31 with the track at the top of the wall having a minimum of 16 gauge thickness and being 2 inches deep to support a plate between the studs.
  • the plate 33 is a 12 gauge to 1/4 inch steel bearing plate with a 2 inch plus projection from each face of the stud track.
  • the thickness depends on the load on the decking and the distance from the face of the stud to the point of bearing.
  • This plate may be welded or screwed to the top wall track.
  • the bottom wall track may be welded or screwed to the plate.
  • a metal angle 34 with one leg equal to the depth of the decking and the projecting leg of 1 1/4 inch or more is used to marry the metal composite span deck 35 to the stud wall assembles.
  • the angle 34 should be the same gauge as the deck and the deck is usually applied to the plate first. The angle is then applied over the deck and fastened to each flute with mastic screws 37 disposed through the outer end 38 of the plate 33, or by welding.
  • a fiber reinforced concrete slab 36 is poured and is continuous through the walls. The concrete is also disposed outside of the bottom track 32 to provide an additional acoustic seal.
  • two or three span conditions can be used.
  • the decking across the top of the wall does not allow multiple stories of the building to be constructed before pouring the floors.
  • By allowing a concrete beam to run through the wall where the composite deck has beams there is a continuous span that allows 4 to 8 foot greater spans with the same slab depth.
  • Negative reenforcing placed through the wall at the deck beams in the top of the slab could create two or three span conditions.
  • Figures 4a and 4b illustrate an assembly that fits the above-description.
  • Figure 4a illustrates a section through the wall
  • Figure 4b illustrates a partial elevation parallel to the wall.

  • Fiber reinforced concrete 46 is disposed over the metal deck 45 and within the cavities of the metal stud 49.
  • Reenforcing bar 47 sized as negative reenforcement for the beams over the top on the wall is installed for two or three span conditions.
  • the reenforcing bar or re-bar is further supported by a wire 48, which is screwed between the studs to support the re-bar in the correct position.
  • Metal top and bottom tracks instead of wood plates and concrete and steel decks instead of wood joists plywood, and gypcrete provide a shrinkage free floor system with more favorable acoustic properties, no flanking paths and a good seal for pipes that must necessarily pierce the floor construction.
