DETAILED DESCRIPTION OF THE INVENTION

An example embodiment floor frame 10 includes two opposite Z-shaped frame members 12, referred to as “Z members” herein, as shown in FIG. 1. Each Z member has a vertical portion or web 14, an upper portion, or upper flange 16, extending generally perpendicularly from an upper end 18 of the web and a lower portion, or lower flange 20, extending perpendicularly or generally perpendicularly from a lower end 22 of the web and in a direction opposite the upper portion so as to define a Z shape in cross-section, as for example shown in FIG. 2. In an example embodiment, the web 14 extends along a length 24 and the upper flange 16 does not extend along the entire length of the web such that it does not extend to the opposite ends 26 of the web defining the length 24, as for example shown in FIG. 1. In an example embodiment as shown in FIGS. 2 and 3, the upper flange extends perpendicularly or generally perpendicularly from the web a longer distance than the lower flange. For example, as shown in FIG. 3, the upper flange has a length 23 that is greater than the length 21 of the lower flange. In an example embodiment, the upper flange has a length 23 of 3 inches as measured from the web, and the lower flange has a length 21 of 2 inches as measured from the web. In an example embodiment as shown in FIG. 3 the web has a length 19 in cross-section of 10 inches.

Tabs 28, and in an example embodiment, rectangular tabs are punched from the web 14, defining openings 30 through the web, at predetermined intervals and extend in the same direction as the lower flange 20, as for example shown in FIG. 2. To punch each tab, a first and a second spaced apart horizontal (or generally horizontal) cuts 32, 34 and a vertical (or generally vertical) cut 36 are formed through the web 14, as for example shown in FIG. 2. Each horizontal cut extends from a first end 38 to a second end 40 in the same direction. The vertical cut extends from the first end 38 of the first horizontal cut to the first end 38 of the second horizontal cut. The tab 18 is bent out (e.g., punched out) along an axis 42 extending from the second end 40 of the first horizontal cut to the second end 40 of the first horizontal cut. Once bent the tab extends perpendicularly or generally perpendicularly to the web of the Z member. In an example embodiment, each Z member is a unitary structure in that it is formed entirely by bending a single sheet of material or panel 13 to have the Z-shape shape and then punching the tabs through its web.

Two end members 44 (FIGS. 1 and 4) are connected to the Z members at each end, as for example shown in FIG. 1. In an example embodiment, each end member 44 is a channel shaped member (referred to herein as a “channel”) having a vertical portion, or web 46 and two generally horizontally flanges (an upper flange 48 and a lower flange 50) extending in the same direction from upper and lower ends 52, 54 of the channel web 46. In an example embodiment, the web of each channel has the same height as the web of each Z member. An end of each channel web is connected to an end of each Z member web respectively. In an example embodiment, this accomplished by using an angle member (not shown) that is attached, in an example embodiment by fasteners 56 (FIG. 1), to the inner surfaces of the webs of each channel member and Z member proximate their corresponding ends. In this regard, the two Z members and the two channels define the perimeter of the floor frame which is a quadrilateral with each Z member and each channel defining a side of the quadrilateral.

Intermediate members 58, which in an example embodiment are C-Studs having a central web 60 and upper and lower flanges 62, 64, extending distally from upper and lower ends 63, 65, respectively of the C-Stud web 60, are connected to corresponding tabs 28 of each Z member (FIGS. 5 and 7). Each C-Stud has an upper lip 68 extending downward from the distal end of the upper flange, and a lower lip 70 extending upward from the distal end of the lower flange. In an example embodiment, instead of C-Studs, I-beams or channels may be used. In an example embodiment, the webs of each C-Stud are fastened proximate their opposite ends to the corresponding tabs of each Z member. In an example embodiment, this is accomplished by using fasteners 71.

A support angle 72 is attached, and in an example embodiment fastened to an outer surface of each end member (e.g., channel member) 44, such that a leg 74 of each support angle member extends in a direction away from the upper flange 48 of each end member 44, as for example shown in FIGS. 1 and 6. In an example embodiment, the upper surfaces of the upper flanges of the Z members, the end members, intermediate members and the support angle legs 48 all extend along the same.

In an example embodiment, the floor frame is attached to four walls 82, 84, 86, 88 forming a room, where at least two opposite walls 82, 86 are bearing walls, as for example shown in FIG. 6A. An upper flange 16 of the first Z-member is rested on an upper end 90 of a first of the two bearing walls and an upper flange of the second Z-member is rested on an upper end 92 of a second of the two bearing walls opposite the first. Each leg 74 of the angle connected to the end member is rested on each of the other two opposite walls, respectively. The webs 14 of each Z member may be attached to the bearing walls 82, 86. In one example embodiment, this may be accomplished by using fasteners 93.

In an example embodiment, retainers 94 are mounted on each wall 82, 84, 86, 88 to support the Z members 12 and the end members 44 at their lower flanges 20, 50, as for example shown in FIGS. 6A, 6B. In an example embodiment, each retainer is a bracket having a first leg 96 for mounting onto the bearing wall and a second leg 98 for mounting and supporting the lower flange 20, 50 of the Z member and end member, respectively, a third leg 100 extending transversely from the second leg 98 in the same direction as the first leg 96 and parallel or generally parallel to the first leg, and a fourth leg 102 extending transversely from the third leg in a direction away from the second leg, and parallel or generally parallel to the second leg. When connected to the lower flanges 20 of the Z members, the retainers may also be connected to the lower flanges 64 of the intermediate members. This example embodiment allows for the retainer to support resilient channels members 105 (also referred to herein as “resilient channels”) that are mounted below the frame transverse to the intermediated members 58 and generally parallel to the Z members. In an example embodiment as shown in FIGS. 6B and 7, the resilient channels comprise a web 107, a first flange 109 extending transversely from one end of the web 107, a second flange 111 extending transversely from an opposite end of the web 107, and a third flange 113 extending transversely from the second flange 111 in a direction away from the web 107 and parallel to the web 107. In the shown example embodiment, the first and second flanges, 109, 111 of the resilient channel extend away obliquely from the web so as to define a truncate cone shape in cross-section as for example shown in FIG. 7. Each resilient channel extends such that each of its ends is received over the flange 102 of a retainer extending along and below the end members 44 and is fastened to the flange 102, as for example shown in FIG. 7. In this regard, the retainers support opposite ends of each of the resilient channels. The resilient channels also extend across the intermediate members and immediately adjacent the lower flanges 64 of the intermediate members. In example embodiments, each resilient channel 105 may also be connected to the lower flanges 64 of the intermediate members 58. The resilient channels help with sound attenuation through the floor and more importantly serve to keep the studs in alignment for a prescribed period of time (for example, two hours) due to overheating during a fire.

A floor board 110, and in an example embodiment a concrete sheath, is placed over the frame extending over the walls. In an example embodiment, the floor board extends the entire thickness 112 of the bearing walls, 82, 86. In another example embodiment, where another floor frame 10 is supported by the same bearing wall, as for example shown in FIG. 7, the floor board extending over each floor frame extends across approximately half of the bearing wall thickness, as for example shown in FIG. 7. The floor board is fastened to the bearing wall 82, 86 through the upper flange 16 of the Z-members, using fasteners 114. In another example embodiment, instead of a single floor board multiple, floor boards may be used adjacent to each other and fastened to the upper flanges of the intermediate members, the Z-members and/or the end members.

The example embodiment floor frame described herein using the example embodiment Z member provides significant improvements from the prior art floor frames 149 currently being used to form floors. For example, as shown in FIG. 8, instead of Z members, channel members 150 are used, as for example shown in FIG. 8. Angle members 152 are used to connect the channel members 150 to the intermediate members. Each angle member has a first leg 153 connected using multiple fasteners 154, as for example five, to a channel member 150, and a second leg 156 attached to the web 60 of the intermediate members using a plurality of fasteners 158, as for example five fasteners. A plurality of additional fasteners 162, as for example five fasteners 162 are then used to connect the angle 152 and the intermediate member 58 connected to the angle to the wall 8, 86. With the example embodiment Z member, instead of the angle, tabs 8 are used and a such one third of the fasteners used in the prior art are used to connect the tabs and the Z member from which they extend to the wall 82, 86. In addition the prior art floor frame requires shims 160 placed between the channel members 150 and the wall 82, 86. Shims are not required when using the example embodiment floor frame described herein mainly because of the Z members and the retainers 94. Moreover, with the prior art floor frames, studs 162 need to be mounted to the walls to support the floor frame prior to the installation of the floor frame. These studs are removed after installation of the floor frame. In addition, some prior art floor frames 149 may also include angles 165 that are connected to the channel members 150 and to the wall 82, 86.
