Abstract
Abstract Disclosed herein is a metal building structure employing box beam upright columns and box beam rafters intermediate the columns, forming a double pitched roof. The columns are of uniform transverse rectangular cross section. The rafters are of transverse rectangular cross section, the height of the cross section increasing from the outer end to the peak of the roof. The lower sides of the rafters are perpendicular to the upright columns. Purlins and girts fastened between the pairs of rafters and the pairs of columns are flush with the sides of the columns and rafters. The columns and rafters are bolted together and channeled passages adjacent the ends provide access to the bolts. An eave strut, connected between the outer ends of the rafters, protrudes outward sufficiently to cover ends of abutting side sheeting, avoiding the need for flashing. A sliding door mounting combines a bracket, carriage, and flashing in an integral piece. The sliding door is comprised of two rectangular frames joined by linking members that vary in size for doors of different height.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
218 words
A metal building structure comprising: pairs of spaced upright columns, each column having a rectangular transverse cross section of uniform size throughout its length; pairs of rafters, each rafter having an outer end carried by one of the columns and connected to its mating rafter intermediate the columns to form a double pitched roof support; each rafter having a rectangular transverse cross section that increases in height from the outer end to the inner end; each rafter having a quadrilateral vertical cross section with parallel outer and inner ends, a bottom side perpendicular to the ends, and a top side at an acute angle with respect to the bottom side equal to a desired roof slope; the rafter's bottom side being substantially perpendicular to the longitudinal axis of the column; the bottoms of said rafters being co-planar and when installed lying in a flat, substantially horizontal plane facilitating installation of a ceiling; a plurality of purlins fastened transversely between each pair of rafters, with the top side of each purlin substantially flush with the top side of the rafter; and a plurality of girts fastened transversely between each pair of columns, with the sides of the girt substantially flush with the sides of the column so as to be co-planar therewith and facilitate installation of an interior wall.
Claim 2
Dependent Claim
218 words
A metal building structure comprising: pairs of spaced upright columns, each column having a rectangular transverse cross section of uniform size throughout its length; pairs of rafters, each rafter having an outer end carried by one of the columns and connected to its mating rafter intermediate the columns to form a double pitched roof support; each rafter having a rectangular transverse cross section that increases in height from the outer end to the inner end; each rafter having a quadrilateral vertical cross section with parallel outer and inner ends, a bottom side perpendicular to the ends, and a top side at an acute angle with respect to the bottom side equal to a desired roof slope; the rafter's bottom side being substantially perpendicular to the longitudinal axis of the column; the bottoms of said rafters being co-planar and when installed lying in a flat, substantially horizontal plane facilitating installation of a ceiling; a plurality of purlins fastened transversely between each pair of rafters, with the top side of each purlin substantially flush with the top side of the rafter; and a plurality of girts fastened transversely between each pair of columns, with the sides of the girt substantially flush with the sides of the column so as to be co-planar therewith and facilitate installation of an interior wall.
Claim 3
Dependent Claim
125 words
The structure of claim 1 further comprising a first plate, having apertures, welded transversely across the top end of each column, the sides of the plate being flush with the sides of the column; a second plate, having apertures, welded transversely across the bottom end of each column, the sides of the plate being flush with the sides of the column; and a third plate, having apertures, welded to the bottom side of each rafter adjacent its outer end, the sides of the plate being flush with the sides of the rafter; said columns and rafters being connected together by bolts inserted through the apertures of the first and third plates; said columns being anchored by studs inserted through the apertures of the second plate.
Claim 4
Dependent Claim
50 words
The structure of claim 2 further comprising a fourth plate, having apertures, welded transversely across the inner end of each rafter, the top and sides of the plate being flush with the sides of the rafter; said rafters being connected together by bolts inserted through the apertures of the plates.
Claim 5
Dependent Claim
24 words
The structure of claim 2 further comprising a channeled passage through each column, adjacent the first and second plates for access to the bolts.
Claim 6
Dependent Claim
15 words
The structure of claim 1 wherein each pair of rafters comprises a single integral beam.
Claim 7
Dependent Claim
70 words
The structure of claim wherein the purlins and the girts have a C-shaped transverse cross section, the structure further comprising: a plurality of clips each having a configuration of a substantially planar surface having slotted apertures spaced and fixedly attached to the columns and rafters, the dimensions of the clips allowing the purlins and girts to be inserted closely thereover; and the purlins and girts being bolted to the clips.
Claim 8
Dependent Claim
74 words
The structure of claim 1 further comprising: an eave strut connected between the outer ends of the rafters, said eave strut having a top side mounted flush with the top side of the rafter, and having an outer side protruding outward from the outer end of the rafter sufficiently to cover the ends of abutting side sheeting and avoiding the necessity for flashing; said eave strut being bolted to plates welded to the rafters.
