Abstract
A blank of a bracket, a bracket, a system using a bracket and a method for mutually securing two or more of a header, a joist and a base, for accurately positioning a header with respect to a base, and for stiffening the webs of a header and a joist to thereby prevent crippling or bending of the webs and to thereby prevent the joist from rolling from side to side. A metal blank can be formed into a bracket which can be used in a system having a header, plural joists and a base whereby the bracket is secured to the header, joist and base for stiffening the webs of C-shaped and/or Z-shaped headers and joists and for aligning and mutually securing the header, joist and base.
Claims49
A one piece bracket for mutually securing a header, a joist abutting the header and a base with a generally planar upper surface supporting the abutting header and joist and with a side surface facing away from the header, said bracket comprising:
- a back plate adapted to overlie the web of the portion of a joist adjacent an abutting header for attachment thereto;
- a first side plate having a major portion extending laterally from the header side of the back plate, the major portion of said first side plate being contiguous to said back plate, stiffening said back plate and being adapted to overlie the web of the header adjacent the abutting joist for attachment thereto, so that the header and the abutting joist may be mutually secured;
- a second side plate having a major portion extending laterally from the other end of said back plate, the major portion of said second side plate being contiguous to said back plate and stiffening said back plate;
- and
- a base plate extending laterally from the bottom of said back plate for stiffening said back plate, said base plate being adapted to overlie the upper surface of the base for attachment thereto where the base supports the mutually secured header and abutting joist,
- wherein said first side plate is L-shaped with a minor terminal portion thereof stiffening the major portion thereof.
A one piece bracket for mutually securing a header, a joist abutting the header and a base with a generally planar upper surface supporting the abutting header and joist and with a side surface facing away from the header, said bracket comprising:
- a back plate adapted to overlie the web of the portion of a joist adjacent an abutting header for attachment thereto;
- a first side plate having a major portion extending laterally from the header side of the back plate, the major portion of said first side plate being contiguous to said back plate, stiffening said back plate and being adapted to overlie the web of the header adjacent the abutting joist for attachment thereto, so that the header and the abutting joist may be mutually secured,
- a second side plate having a major portion extending laterally from the other end of said back plate, the major portion of said second side plate being contiguous to said back plate and stiffening said back plate;
- and
- a base plate extending laterally from the bottom of said back plate for stiffening said back plate, said base plate being adapted to overlie the upper surface of the base for attachment thereto where the base supports the mutually secured header and abutting joist,
- wherein said second side plate is L-shaped with the minor terminal portion thereof stiffening the major portion thereof.
A three component system for supporting a generally horizontal surface comprising:
- a header having a generally vertical web and an upwardly facing side surface;
- a plurality of joists abutting said header at spaced intervals along the length thereof, each of said joists having a generally vertical web and an upwardly facing side surface generally coplanar with the upwardly facing side surface of said header for supporting a generally horizontal surface;
- a base having an upwardly facing surface supporting said header and the header abutting end of said plurality of joists;
- and
- a plurality of one piece brackets each comprising:
- a back plate attached to the web of one of said joists,
- a first side plate laterally extending from a side of said back plate to effect the stiffening thereof and the stiffening of the web of the joist to which said back plate is attached, said first side plate being attached to the web of said header so that said back plate stiffens the web of said header, and
- a base plate laterally extending from said back plate to effect the stiffening thereof and thus of the web of the header, said base plate being attached to the upwardly extending surface of said base,
- whereby said header and said plurality of joists are attached to each other and to said base and provide support for a generally horizontal surface when overlain thereon.
A two component system for securing joists to a girder comprising:
- a girder having a generally vertical web and an upwardly facing side surface;
- a plurality of joists supported by said girder at spaced intervals along the length thereof;
- a plurality of one piece brackets each comprising:
- a back plate attached to the web of one of said joists,
- a first side plate laterally extending from a side of said back plate to effect the stiffening thereof and the stiffening of the web of the joist to which said back plate is attached,
- a second side plate laterally extending from a side of said back plate to effect the stiffening thereof and the stiffening of the web of the joist to which said back plate is attached, and
- a base plate laterally extending from said back plate to effect the stiffening thereof and thus of the web of the joist, said base plate being attached to the upwardly extending surface of said girder,
- whereby said girder and said plurality of joists are attached to each other.
A method of mutually attaching a C-shaped or Z-shaped metal header to an abutting C-shaped or Z-shaped metal joist to a supporting base with stiffening of the header and the joist comprising the steps of:
- (a) providing a metal bracket with a back plate, a first generally normal extension from one end thereof and a second generally normal extension from one side thereof;
- (b) positioning the bracket with the back plate overlying the web of the joist and with second extension overlying the web of the header and with the first extension overlying the base;
- and
- (c) securing surfaces of the bracket to the surfaces overlain so that the back plate serves to stiffen the web of the header, the second extension stiffens the back plate and thus the web of the header, and the first extension stiffens the back plate and the web of the joist,
- the securing also mutually attaching the header to the joist to the base,
- whereby the header and joist are stiffened and secured to the base.
A method of mutually attaching a C-shaped or Z-shaped metal joist to a girder with stiffening of the joist comprising the steps of:
- (a) providing a metal bracket with a back plate, a first generally normal base plate extending from one end thereof and first and second generally normal side plates extending one each from opposite sides thereof;
- (b) positioning the bracket with the back plate overlying the web of the joist and with the base plate overlying the girder and;
- and
- (c) securing the base plate of the bracket to the girder and the back plate to the web of the joist so that the back plate serves to stiffen web of the joist, the two side plates stiffen the back plate and thus the web of the joist
- whereby the joist is stiffened and secured to the girder.
