Abstract
A wall system for forming a weather enclosure across a building opening in the frame of a building includes a flexible sheet of flexible material, a first rigid frame member secured across a first end of the flexible sheet, and a second rigid frame member secured across the flexible sheet in proximity to an opposing second end of the sheet. The first rigid frame remember is fixedly mounted on the building frame. A tensioning assembly is operatively connected between the second rigid frame member and the building frame so as to apply tension in the longitudinal direction to a portion of the flexible sheet. The tensioning between rigid frame members spanning across opposing ends of the sheet ensures that the sheet can be supported under significant tension throughout the sheet to enable the sheet to withstand considerable wind and precipitation loads.
Description
TENSIONED SHEET WALL SYSTEM FOR A BUILDING
FIELD OF THE INVENTION
The present invention relates to a wall system in which flexible sheet material is tensioned to span across the frame of a building, for example to provide a temporary weather enclosure supported on the frame of a building while the building is under construction.
BACKGROUND
During the construction of large commercial buildings, it is common practice to initially erect a building frame comprised of posts and beams and roof trusses followed by subsequent mounting of rigid panels of various types to form permanent walls of the building. While assembling the building frame and/or preparing the building for mounting wall panelling onto the frame, it is often desirable to provide a weather enclosure about the building to allow heating of the interior space of the building. Some heating of the interior space may be required to assist in curing of various materials such as concrete, or for comfort of construction workers within the building space. As a temporary means of forming a weather enclosure, it is common practice to support sheets of plastic type material directly on the building frame or on scaffolding surrounding a building frame. The plastic material however may be required to span large distances on large commercial buildings and the plastic material is typically not well supported for withstanding wind loads or loads from precipitation and the like such that the panels become torn and require replacement even during short-term use for construction.
US patents 5,613,543 by Walton and 3,805,816 by Nolte, and W097/48863 by Nylander disclose various examples of a temporary protective covering used in construction. In each instance however, only small sheets are provided for

3 between the frame members ensures that the flexible sheet can be supported under significant tension throughout the sheet in a manner that enables the sheet to withstand considerable wind loads. The flexible sheet typically comprises a high-quality fabric material with abrasion resistance and tear resistant properties by providing an enhanced coating on a woven plastic fibers sheet. The flexible sheets thus offer safer building envelopes which protect buildings and materials and equipment within the temporary building structure from harsh and unpredictable weather.

DETAILED DESCRIPTION
Referring to the accompanying figures there is illustrated a fabric wall system generally indicated by reference numeral 10. The system 10 is particularly suited for use in forming a temporary or semi-permanent weather enclosure about the frame 12 of a building, for example during construction of the building before rigid wall panels are installed on the frame.
10 A typical commercial building frame 12 includes a plurality of posts spaced apart along each wall of the building with each wall further including a header spanning across the posts at the elevation of each floor and the roof of the building for supporting floor beams and roof trusses on the headers. The posts typically extend upwardly from a foundation which may comprise additional framing or a concrete pad for example that forms the base of the building frame. The building frame 12 defines a plurality of building openings in which each building opening includes a perimeter that is bound at laterally opposing sides by a respective post 14, is bound by framing or a foundation 16 at the bottom side of the opening, and is bound by a header 18 at the top side of the opening. At upper levels of the building frame, the bottom of the perimeter of each building opening is typically bound by an additional header 18.
The wall system 10 according to the present invention generally uses a flexible fabric sheet 24 spanning the building opening under tension. The fabric sheet typically comprises a flexible material, for example plastic fibers which are woven together and/or coated so as to define either (i) a single ply of material, or (ii) when insulation is desired, two plies of material with additional insulating layers optionally provided therebetween if desired. The coating provides abrasion and heat resistance, and ultraviolet resistance, while ensuring that the sheet 20 remains flexible.
The fabric sheet 24 spans in a longitudinal direction a full length of the sheet between a first end 22 at the top end and a second end 24 at the bottom end of the sheet. The sheet also spans in a lateral direction perpendicular to the longitudinal direction across a full width between two opposing side edges 26.
Each building opening may be covered by a fabric sheet 20 comprising a single continuous sheet of material or a plurality of sheet sections 28 which are joined together. In the illustrated embodiment, the fabric sheet 20 is formed of multiple sheet

The coating provides abrasion and heat resistance, and ultraviolet resistance, while ensuring that the sheet 20 remains flexible.
The fabric sheet 24 spans in a longitudinal direction a full length of the sheet between a first end 22 at the top end and a second end 24 at the bottom end of the sheet. The sheet also spans in a lateral direction perpendicular to the longitudinal direction across a full width between two opposing side edges 26.
Each building opening may be covered by a fabric sheet 20 comprising a single continuous sheet of material or a plurality of sheet sections 28 which are joined together. In the illustrated embodiment, the fabric sheet 20 is formed of multiple sheet
11 sections 28 connected laterally in series with one another such that each sheet section spans the full height between the top end 22 and the bottom end 24 while only spanning a part of the width in the lateral direction between the opposing side edges 26. The seams between adjacent sheet sections can be joined by various means including heat welding, gluing or stitching if a permanent seam is desired, or use of hook and loop fasteners, zippers, or laces tied through grommets and the like if it is desirable to subsequently separate the sheet sections from one another.
At the top end 22 of the sheet, an elongate strand of material, for example a nylon rope is embedded within the plastic material forming the body of the fabric sheet 20 so as to form a bead 30 of increased thickness relative to the remainder of the sheet, extending laterally across the full width of the flexible sheet at the top edge thereof.
A similar bead 30 may also be provided along the bottom edge when the flexible sheet is used in a multi-level application where it is desirable for the bottom edge of the sheet to be joined continuously with the top edge of another sheet therebelow.
Turning now more particularly to the first embodiment of the system 10 as shown in figures 1 through 5, the system includes a retainer member 32 comprising a rigid frame member which is arranged to be fastened to the header 18 along the top side of the building opening so that the retainer member 32 spans the full width of the building opening and the full width of the corresponding flexible fabric sheet 20 that spans the opening. The retainer member 32 is an extruded member having a constant profile along the full length thereof in the lateral direction of the sheet.
The profile includes two channel portions 34 formed along opposing sides of the retainer member in which each channel portion comprises a hollow channel of generally circular cross-section with an interior diameter that closely matches the exterior diameter of the bead

The retainer member 32 is an extruded member having a constant profile along the full length thereof in the lateral direction of the sheet.
The profile includes two channel portions 34 formed along opposing sides of the retainer member in which each channel portion comprises a hollow channel of generally circular cross-section with an interior diameter that closely matches the exterior diameter of the bead

The flexible sheet 20 is thus effectively tensioned in the longitudinal direction between the first end 22 at the top of the sheet and the mounting location of the pocket 40 on the flexible sheet 20 in proximity to the bottom second and 24 thereof.
A remaining end portion 62 of the flexible sheet 20 is defined between the mounting location of the pocket 40 of the tension member 48 and the bottom second end 24 of the flexible sheet. The end portion 62 spans in the longitudinal direction of the sheet by an overall height of the tension assembly between the mounting location .. of the tension member and the bottom of the building opening. When a bottom bead is provided, the bottom edge can also be secured in fixed relation to the building frame to provide a continuous weather barrier spanning across the corresponding opening in the building.
When used at upper levels of a building structure where a safety railing is required to prevent construction workers from falling over the outer edges of the upper
15 levels, the wall system 10 may further include a railing assembly as described in the following. The railing assembly includes a railing pocket 64 formed onto the inner surface of the flexible sheet 20. Similarly, to the tensioning pocket, the railing pocket also comprises a fabric panel spanning the full width of the flexible sheet 20 in the lateral direction thereof. Opposing top and bottom edges 66 and 68 of the fabric panel forming the railing pocket are joined to the flexible sheet using respective rows of stitching 70 or other permanent fasting means including heat welding or adhesive and the like. The fabric panel is longer between top and bottom edges than the spacing between the stitching rows 70 such that the panel is able to protrude inwardly from the inner surface of the flexible sheet 20 in a triangular shape towards an inner apex 70 so as to define a triangular shape of the hollow interior of the pocket 64 at the inner surface of the flexible sheet 20.
The railing system further includes a rigid railing member 74 in the form of a rigid, tubular frame member, for example an extruded hollow plastic or metal tube or pipe, which spans the full width of the flexible sheet 20 in the lateral direction between corresponding posts at laterally opposing sides of the corresponding building opening.

Another winch 78 having a which body and winch drum as described above is mounted on the second flange using suitable fasteners to fix the winch body to the second flange of the bracket.
A tension cable 80 is provided in the form of an elongate rope or other strand material such as a steel cable, which is wound at opposing ends onto the
16 winches 78 of the two frame mounts 76 at laterally opposing sides of the corresponding building opening. One or both winches is operated to provide tension to the cable 80 in the lateral direction. The cable 80 is inserted through the hollow interior of the rigid railing member 74 to extend longitudinally within the rigid railing member across the full length thereof in the lateral direction of the flexible sheet 20. The flexible sheet is typically supported to be substantially flush with the exterior side of the building frame while the frame mounts for the railing assembly are supported at the inner surface of the building frame such that the rigid railing member 74 supported by the tension cable 80 between the frame mounts 76 is positioned at a location spaced perpendicularly inward from the plane of the flexible sheet 20.
The flush mounting of the flexible sheet 20 with the exterior side of the building readily allows adjacent flexible sheets 20 at two adjacent building openings of the building to be joined to one another to form a continuous barrier sheet across the exterior of the building frame. Typically, the adjacent sheets are joined with releasable fasteners such as hook and loop fasteners, zippers, or laces tied between grommet openings along the side edges of the adjacent flexible sheets 20 respectively.
The fabric panel forming the railing pocket 64 includes a plurality of cut-out openings 82 formed therein at the inner apex 72 of the pocket at spaced apart positions from one another in the lateral direction of the flexible sheet so as to be spaced apart along the length of the railing member.

The flush mounting of the flexible sheet 20 with the exterior side of the building readily allows adjacent flexible sheets 20 at two adjacent building openings of the building to be joined to one another to form a continuous barrier sheet across the exterior of the building frame. Typically, the adjacent sheets are joined with releasable fasteners such as hook and loop fasteners, zippers, or laces tied between grommet openings along the side edges of the adjacent flexible sheets 20 respectively.
The fabric panel forming the railing pocket 64 includes a plurality of cut-out openings 82 formed therein at the inner apex 72 of the pocket at spaced apart positions from one another in the lateral direction of the flexible sheet so as to be spaced apart along the length of the railing member. Each cut-out opening 82 defines an access opening in alignment with the railing member to fully expose the respective portion of the railing member with additional space surrounding the railing member such that the railing member can be readily grasped in the hand of a user at each opening 82.
In use, the wall system is typically mounted onto a building frame by initially fastening the retainer member 32 across the top side of the corresponding
17 building opening to be covered. The top edge of the flexible sheet 20 can then be inserted into a corresponding channel portion of the retainer member by sliding the bead at the top edge of the flexible sheet into the retainer member in the lateral direction of the sheet until the sheet is aligned with the building opening. If securing the bottom end of the sheet with a corresponding bead in a channel, the bottom bead is also inserted into the respective frame member along the bottom side of the corresponding building opening. The tension member 42 is then inserted into the pocket at the inner side of the flexible sheet 20 with the winch straps 56 being extended about the tension member. With the winch bodies fixed along the bottom of the building opening, further operation of the winches will pull the tension member downwardly to longitudinally tension the sheet between (i) the top first end 22 and (ii) the mounting location of the tension member in proximity to the bottom second end 24. The railing member 74 is then inserted into the railing pocket 64 and the tension cable 80 is tensioned in the lateral direction through the railing member between frame mounts 76 mounted on the building frame.
Turning now to the second embodiment according to figures 6 through 10, in this instance the flexible sheet is provided for again spanning over a respective building opening in the building, however the retainer member 32 across the top side of the building opening according to the first embodiment is instead replaced with an auxiliary retainer member 100 which defines a track for supporting the flexible sheet 20 to be slidable in a lateral direction between a closed position spanning the associated building opening and an open position in which the building opening is substantially unobstructed by the flexible sheet so as to function as a doorway.

In this instance, the retainer member 100 comprises a rigid frame member in the form of a hollow tube of square cross section in which a slot 102 is formed in the
18 bottom side of the tube to extend along the full length of the tube in the lateral direction.
The slot is centred between opposing sides of the tube so as to define a pair of side flanges 104 protruding inwardly towards one another on opposing sides of the slot at the bottom wall of the tube forming the retainer member 100.
A plurality of carriage members 106 are supported within the hollow interior of the retainer member so as to be supported for sliding or rolling movement along the length of the retainer member corresponding to the lateral direction of the sheet 20. Each carriage member includes a central body 108 supporting two wheels 110 thereon at opposing sides of the body for rolling movement along respective ones of the two side flanges 104 of the retainer member. A depending hook 112 extends downwardly from the central body 108 through the bottom slot 102 for being hooked into a respective hook opening 114 in proximity to the top edge of the flexible sheet 20.
A plurality of the carriage members 106 are provided at laterally spaced apart positions across the width of the sheet so as to support the sheet across the width thereof.
In further embodiments, a rigid member may be coupled to the top edge of the sheet which is in turn secured relative to the carriage members 106 using suitable hooks or fasteners of various types which communicate through the bottom slot 102 of the retainer member so as to be movable along a slot together with movement of the flexible sheet in the lateral direction relative to the track formed by the retainer member 100.
In the embodiment of figures 6 through 10, the remainder of the wall system 10 is substantially identical to the previous embodiments with regard to a tensioning pocket 40 that receives a tension member 48 therein which is secured by tensioning devices 50, as well as a railing assembly comprised of a rigid railing member 74 received within a railing pocket 64.

In the second embodiment however the
19 tensioning assemblies remain readily releasable from the fabric sheet 20. In this instance, when it is desired for the door opening in the building to remain closed, the tensioning assemblies and the railing assembly remain secured between the flexible sheet and the building frame. However, when it is desired to open the door opening in the building, the tensioning assembly and the railing assembly are released so as to disconnect the flexible sheet from the building frame and support the flexible sheet 20 entirely by the carriage members 106 along the top edge thereof.
As shown in figures 9 and 10, when it is desirable to form the building frame with a door opening 120 between two adjacent building openings 122 which are intended to remain closed by the wall system 10, a first flexible sheet 20 and a second flexible sheet 20 according to the first embodiment of figures 1 through 5 are initially mounted in fixed relation across each of the building openings 122.
