Abstract
Abstract There is provided an improved wall construction including a vertical mullion assembly and a horizontal member assembly. Both assemblies are formed of interlocking gutter and face sections defining opposed glazing channels. The horizontal member assembly is provided with a pair of longitudinally extending screw splines. The assemblies may be joined in accordance with an improved shear pin system wherein the vertical mullion assembly is prepared for attachment of a horizontal member by drilling holes to receive the head of a shear pin and a dowel pin. The horizontal members are prepared by the insertion of a shear pin into one of the screw splines formed in the horizontal member and by the insertion of a dowel pin into the other of the screw splines formed in the horizontal member assembly. The horizontal member is then attached to the vertical by intalling the heads of the shear pin and the dowel pin into the holes previously drilled for them.

Total Claims: 8
Claim 1
Independent Claim
102 words
A wall construction including a through vertical mullion and a horizontal member abutting against said vertical mullion, said horizontal member having at least a pair oF longitudinally extending screw splines, a shear pin fastener threaded into the end of one of said screw splines having an enlarged head portion projecting therefrom, said vertical mullion having a pair of spaced holes, said head portion being inserted through one of said holes and bottomed thereon to secure said horizontal member with said vertical mullion, and a dowel pin inserted into the other of said screw splines and received in the other of said holes.
Claim 2
Dependent Claim
102 words
A wall construction including a through vertical mullion and a horizontal member abutting against said vertical mullion, said horizontal member having at least a pair oF longitudinally extending screw splines, a shear pin fastener threaded into the end of one of said screw splines having an enlarged head portion projecting therefrom, said vertical mullion having a pair of spaced holes, said head portion being inserted through one of said holes and bottomed thereon to secure said horizontal member with said vertical mullion, and a dowel pin inserted into the other of said screw splines and received in the other of said holes.
Claim 3
Dependent Claim
172 words
A wall construction including a through vertical mullion and a horizontal member abutting against said vertical mullion, said horizontal member having at least a pair of longitudinally extending, transversely spaced screw splines, a shear pin fastener secured into the end of one of said screw splines having a shank and an enlarged head portion projecting therefrom, said head portion including an inner arcuate bearing spacer section eccentric with said shank, said vertical mullion being formed of a member having a transverse web and cross webs, said transverse web having a pair of pin receiving openings of a radius approximately equal to the radius of the arcuate portion of said bearing spacer section, the enlarged head portion of said pin projecting through one of said openings with said arcuate bearing spacer section resting on said transverse web, a dowel pin having a shank installed in the other of said splines and having a head with a radius approximately equal to the radius of said openings and fitted into the other of said openings.
Claim 4
Dependent Claim
172 words
A wall construction including a through vertical mullion and a horizontal member abutting against said vertical mullion, said horizontal member having at least a pair of longitudinally extending, transversely spaced screw splines, a shear pin fastener secured into the end of one of said screw splines having a shank and an enlarged head portion projecting therefrom, said head portion including an inner arcuate bearing spacer section eccentric with said shank, said vertical mullion being formed of a member having a transverse web and cross webs, said transverse web having a pair of pin receiving openings of a radius approximately equal to the radius of the arcuate portion of said bearing spacer section, the enlarged head portion of said pin projecting through one of said openings with said arcuate bearing spacer section resting on said transverse web, a dowel pin having a shank installed in the other of said splines and having a head with a radius approximately equal to the radius of said openings and fitted into the other of said openings.
Claim 5
Dependent Claim
219 words
A wall construction including a through vertical mullion assembly and a horizontal framing assembly abutting against said vertical mullion assembly, each of said assemblies including a gutter frame section and a face frame section, each gutter frame section including an inner face portion and a main web normal thereto intermediate the ends of said face portion and each face frame section including an outer face portion and a main web normal thereto intermediate the ends of said frame portion, means associated with each of said assemblies interlocking the main webs of the gutter and face portions to define opposed glazing channels, the face portion of said horizontal member having at least a pair of longitudinally extending transversely spaced screw splines; a shear pin fastener threaded into the end of the screw splines closest to said glazing channels and having an enlarged head portion projecting therefrom, said vertical mullion assembly having a pair of spaced holes, said head portion being inserted through one of said holes and bottomed thereon to secure said horizontal framing assembly with said vertical mullion assembly, and a dowel pin inserted into the other of said screw splines and having a head received in the other of said holes, the head of said dowel pin having a radius approximately equal to the radius of said holes.
Claim 6
Dependent Claim
219 words
A wall construction including a through vertical mullion assembly and a horizontal framing assembly abutting against said vertical mullion assembly, each of said assemblies including a gutter frame section and a face frame section, each gutter frame section including an inner face portion and a main web normal thereto intermediate the ends of said face portion and each face frame section including an outer face portion and a main web normal thereto intermediate the ends of said frame portion, means associated with each of said assemblies interlocking the main webs of the gutter and face portions to define opposed glazing channels, the face portion of said horizontal member having at least a pair of longitudinally extending transversely spaced screw splines; a shear pin fastener threaded into the end of the screw splines closest to said glazing channels and having an enlarged head portion projecting therefrom, said vertical mullion assembly having a pair of spaced holes, said head portion being inserted through one of said holes and bottomed thereon to secure said horizontal framing assembly with said vertical mullion assembly, and a dowel pin inserted into the other of said screw splines and having a head received in the other of said holes, the head of said dowel pin having a radius approximately equal to the radius of said holes.
Claim 7
Dependent Claim
131 words
A wall construction including a through vertical mullion assembly and a horizontal framing assembly abutting against said vertical mullion assembly, each of said assemblies including parts defining opposed glazing channels, said horizontal member having at least a pair of longitudinally extending transversely spaced screw splines on one side of said glazing channels; a shear pin fastener threaded into the end of the screw splines closest to said glazing channels and having an enlarged head portion projecting therefrom, said vertical mullion assembly having a pair of spaced holes, said head portion being inserted through one of said holes and bottomed thereon to secure said horizontal framing assembly with said vertical mullion assembly, and a dowel pin inserted into the other of said screw splines and received in the other of said holes.
