Description
TITLE:
Fire Resistant Building Framing System FIELD
The present invention relates to a building framing system onto which sheeting panels are placed.
BACKGROUND
It was thought that wood frame construction could be made more fire resistant by covering the wood frame with fire resistant sheeting panels, such as magnesium board.
However, it has been discovered that instantaneous combustion of the wood frame occurs when a flash temperature is reached. There is, therefore, a need for a more fire resistant framing system onto which fire resistant sheeting panels may be placed.
SUMMARY
There is provided a fire resistant building framing system, which includes a plurality of construction studs and at least one end shield. Each construction stud includes an elongated core having a first end, a second end, opposed faces and opposed edges. A fire resistant mineral board strip overlies the opposed edges of the core and extends for substantially a length of the core while leaving at least one of the first end or the second end uncovered. The mineral board strip extends beyond the opposed faces of the core to give each construction stud an "I" configuration. Each end shield includes an elongated body made from fire resistant mineral board and defining a "C" shaped channel with a parallel panel members tied by a connecting member. The at least one end shield shields the opposed edges of the uncovered first end or the uncovered second end of the core of each construction stud. The panel members of the elongated body of the end shield being substantially the same thickness as the mineral board overlying the opposed edges of the core, thereby providing a planar surface along the opposed edges of the core of the construction stud which accommodates sheeting panels.

DETAILED DESCRIPTION
A first embodiment of fire resistant building framing system will be described with reference to FIG. 1 through 4. A second embodiment of fire resistant building framing system will be described with reference to FIG. 5 through 7.
Structure and Relationship of Parts:
Referring to FIG. 1, fire resistant building framing system includes a plurality of construction studs 12 and end shields 14. Referring to FIG. 2, each construction stud 12 includes an elongated core 16 having a first end 18, a second end 20.
Referring to FIG. 3, each construction stud 12 has opposed faces 22, 24 and opposed edges 26, 28.
Fire resistant magnesium mineral board strips 30 overlie opposed edges 26, 28 of core 16.
Referring to FIG. 2, mineral board strips 30 extend for substantially a length of core 16 while leaving at least one of first end 18 or second end 20 uncovered. Referring to FIG. 3, mineral board strips 30 extend beyond opposed faces 22, 24 of core 16 to give each construction stud 12 an "I" configuration.
Referring to FIG. 1, each end shield 14 includes an elongated body 32 made from fire resistant magnesium mineral board. Referring to FIG. 4, elongated body 32 defines a"C"
shaped channel 34 with parallel panel members 36 tied by a connecting member 38.
Referring to FIG. 1, end shields 14 span more than one construction stud 14.
Referring to FIG. 2, end shields 14 shield opposed edges 26, 28 of each of uncovered first end 18 and uncovered second end 20 of core 16 of each construction stud 16. Referring to FIG. 1, panel members 36 of elongated body 32 of end shield 14 are substantially the same thickness as mineral board strips 30 overlying opposed edges 26, 28 of core 16. This provides the resulting frame with a planar surface 40 along opposed edges 26, 28 of core 16 of construction stud 12 which accommodates sheeting panels (not shown).
Core 16 can be made from any suitable materials, such as wood, structural foam, fibreglass or fibre-reinforced plastic. With wood or structural foam, core 16 is solid. With fibreglass or fibre-reinforced plastic, core 16 is hollow or filled with foam.
Wood, fibreglass and fibre-reinforced plastic retain fasteners fairly well. Structural foam does not. Referring to FIG. 5 through 7 there is shown a second embodiment which was developed expressly for the purpose of improving the ability of structural foam to retain fasteners. In this embodiment, core 16 includes both foam and wood. Fastener retaining wood layers 42 are positioned along each of opposed edges 26, 28 and an intermediate foam layer 44 is sandwiched between wood layers 42. Otherwise, the construction and function of this second embodiment is the same as described in relation to the first embodiment. In the second embodiment, end shield 14 has also been provided with wood layers 42. In order to be effective for fastener retention, wood layers 42 must be more than a mere veneer. Beneficial results have been obtained when wood layers 42 have a minimum thickness of one eighth of an inch in order to ensure fastener retention.
It will be understood that the building framing system described above can be used to construct various components of a building, such flooring, walls, ceilings, roofing, etc.
In addition, it will be understood that the stud and end shield components discussed above may also be used as connectors with structural insulated panels, in addition to the use as conventional structural elements described above.
Advantages:
In the prior art, when mineral board sheeting panels were placed over a wood frame construction, the sheeting panels were abutted and secured to a wood stud.
However, it was unavoidable that a gap between the abutting sheeting panels would leave the wood stud exposed. Referring to FIG. 1, it is to be noted that mineral board strips 30 protect opposed edges 26, 28 of core 16 of construction stud 12 so that this does not occur.
In the prior art, the wood frame was also vulnerable to heat from above and below. It is to be noted that end shields 14 protect first end 18 and second end 20 of core 16 of construction stud 12 so that this does not occur. It will be appreciated that any fire resistant mineral board may be used.
Beneficial results have been obtained through the use of magnesium mineral board, which appears to be particularly effective.
In this patent document, the word "comprising" is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article "a" does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiments without departing from scope of the Claims.
Referring to FIG. 2, end shields 14 shield opposed edges 26, 28 of each of uncovered first end 18 and uncovered second end 20 of core 16 of each construction stud 16. Referring to FIG. 1, panel members 36 of elongated body 32 of end shield 14 are substantially the same thickness as mineral board strips 30 overlying opposed edges 26, 28 of core 16. This provides the resulting frame with a planar surface 40 along opposed edges 26, 28 of core 16 of construction stud 12 which accommodates sheeting panels (not shown).
Core 16 can be made from any suitable materials, such as wood, structural foam, fibreglass or fibre-reinforced plastic. With wood or structural foam, core 16 is solid. With fibreglass or fibre-reinforced plastic, core 16 is hollow or filled with foam.
Wood, fibreglass and fibre-reinforced plastic retain fasteners fairly well. Structural foam does not. Referring to FIG. 5 through 7 there is shown a second embodiment which was developed expressly for the purpose of improving the ability of structural foam to retain fasteners. In this embodiment, core 16 includes both foam and wood. Fastener retaining wood layers 42 are positioned along each of opposed edges 26, 28 and an intermediate foam layer 44 is sandwiched between wood layers 42. Otherwise, the construction and function of this second embodiment is the same as described in relation to the first embodiment. In the second embodiment, end shield 14 has also been provided with wood layers 42. In order to be effective for fastener retention, wood layers 42 must be more than a mere veneer. Beneficial results have been obtained when wood layers 42 have a minimum thickness of one eighth of an inch in order to ensure fastener retention.
