Abstract
Abstract A fixing bracket 5 in a roof construction is a metal sheet with two parallel grooves 39, 40 pressed therein to protrude as ribs from the other side of the sheet, each groove extending from one edge of the sheet to another with two straight end portions and a central part-circular central portion. The outer edge of the sheet is concentrically part-circular and the inner edge is folded up at 38. Such a bracket, or a pair of such brackets back-to-back with grooves 39, 40 protruding, can connect cold-rolled channels 1, 2 e.g. as used for the uprights or rafters of a portal frame structure, with compatible longitudinal base grooves. The channels are again usually used in back-to-back pairs and the brackets are bolted within these back-to-back pairs of channels. The included angle can be from 90-136° for eaves brackets, or from 90-180° for ridge brackets.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
233 words
l.A fixing bracket for joining the ends of two lengths of cold-rolled metal channel each channel having a flat base with two longitudinal parallel strengthening grooves rolled into the thickness so as to protrude as longitudinal convex ribs within the channel; characterised in that:(i)the bracket is in the form of a metal sheet also having two parallel strengthening grooves formed in the thickness thereof so as to protrude as ribs on the reverse side of the sheet, each such groove extending from a first edge to a second edge of the sheet;(ii)the median line of the bracket grooves extends (a) as two end portions, inward in straight lines from the two said edges of the sheet, the said straight lines intersecting at a desired fixing angle and (b) as a communicating central portion, around an arc of a circle so as to connect the two straight lines;and (iii) the size and spacing of the bracket grooves are such that the bracket ribs fit into the concave channel grooves, outside of the channel base; whereby the end region of a first channel can be placed over one end portion of the bracket ribs and the end region of a second channel over the other end portion of the bracket ribs, with respective radially inner channel end corners adjacent, and fixed in relation to the bracket with the channels extending at the desired fixing angle.
Claim 2
Dependent Claim
46 words
A fixing bracket as claimed in claim 1 characterised in that one edge of the bracket is shaped as an arc of a circle concentric with the said central groove portion, and dimensioned so as to meet the radially outer end corners of the said channel.
Claim 3
Dependent Claim
29 words
A fixing bracket as claimed in claim 1 or 2 characterised in that an edge of the bracket is turned out of its plane as a reinforcement against buckling.
Claim 4
Dependent Claim
37 words
A fixing bracket as claimed in claim 4 characterised in thatthe upturned edge lies within the fixing angle of the channels, and is of a length such that its ends meet the outside of the channel walls.
Claim 5
Dependent Claim
48 words
A fixing bracket as claimed in any one of claims 1 to 4 characterised in that the said fixing angle is from 900 to 135 0 included angle whereby the bracket is suitable as an eaves bracket for fitting between wall columns and rafters in a roof construction.
Claim 6
Dependent Claim
46 words
A fixing bracket as claimed in any one of claims 1 to 4 characterised in that the said fixing angle is from 90 0 to 180 0 included angle whereby the bracket is suitable as a ridge bracket for fitting between rafters in a roof construction.
Claim 7
Dependent Claim
72 words
An assembly comprising either a single bracket as claimed in any one preceding claim, or a pair of such brackets located back to back with ribs protruding from each outer face, characterised in that one such channel is attached to an end portion of the bracket or bracket pair or in that two such channels arranged base to base are attached with such bracket or bracket pair end portion located between them.
Claim 8
Dependent Claim
36 words
An assembly as claimed in claim 7 characterised in that the or each said channel possesses vertical walls, inwardly rolled upper wall edges parallel to the base, and inwardly rolled edge lips parallel to the walls.
Claim 9
Dependent Claim
72 words
A cold-rolled steel portal frame structure, of the type in which a building of any desired length is built up from parallel transverse structural elements each comprising side columns and rafters, one rafter being attached to the top of each column and the rafters being mutually attached at the roof ridge; characterised in that the columns and rafters all have a like profile consisting of two identical channel-shaped cold-rolled steel profiles back-to-back.
Claim 10
Dependent Claim
41 words
A structure as claimed in claim 9 which further comprises horizontal purlins between adjacent parallel raftersand/or horizontal side-rails between adjacent parallel columns, characterised in that each such purlin having a profile identical with one of the two rafter or column components.
Claim 11
Dependent Claim
39 words
A structure as claimed in claim 10 characterised in thatthe side rail outer walls lie in the same plane as the column outer walls, and the purlin outer walls lie in the same plane as the rafter outer walls.
Claim 12
Dependent Claim
57 words
A structure as claimed in claim 9 characterised in that in which rafters join the columns, or join each other, in such a way that the rafter and column ends viewed from within the structure (or two rafter ends viewed from within the structure) are essentially contiguous,and are constituted by an assembly as claimed in claim 6.
