Abstract
Abstract This invention relates to a metal plate curtain wall structure. The joints of the metal plate structure are sealed weathertight without exposed caulking. A second line defense against water infiltration is formed by a concealed internal drainage system without exposed weep holes eliminating the water stain problem under the weep holes and enhancing the architectural appearance. A plate connection system securely fastened to the structural support is slidable in the direction parallel to the plate surface allowing free thermal expansion of the plate without weakening the resistance against wind load acting normal to the plate surface. The connection system is also designed to absorb any conceivable dimensional tolerance of the support frame facilitating the easiness of field erection.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
123 words
A metal plate exterior wall structure comprising a number of individual panels securely fastened to a wall supporting frame system, both vertical and horizontal sealed reveal joints being formed between said panels, each individual panel including a front plate and a top perimeter member, two side perimeter members, and one bottom perimeter member, the perimeter members being structurally connected to the front plate and sealed thereto along their perimeters in between, the improvements comprising an internal horizontal gutter in said top perimeter member said top perimeter member having an enclosed hollow space with exterior end openings below said internal horizontal gutter, at least one hole at the bottom of the said internal horizontal gutter for leading condensate into the said enclosed hollow space.
Claim 2
Dependent Claim
123 words
A metal plate exterior wall structure comprising a number of individual panels securely fastened to a wall supporting frame system, both vertical and horizontal sealed reveal joints being formed between said panels, each individual panel including a front plate and a top perimeter member, two side perimeter members, and one bottom perimeter member, the perimeter members being structurally connected to the front plate and sealed thereto along their perimeters in between, the improvements comprising an internal horizontal gutter in said top perimeter member said top perimeter member having an enclosed hollow space with exterior end openings below said internal horizontal gutter, at least one hole at the bottom of the said internal horizontal gutter for leading condensate into the said enclosed hollow space.
Claim 3
Dependent Claim
24 words
A wall structure as recited in claim 1 together with dams at both ends of said internal horizontal gutter of said top perimeter member.
Claim 4
Dependent Claim
24 words
A wall structure as recited in claim 1 wherein said top perimeter member has a substantially U-shaped vertically upward extension forming said horizontal gutter.
Claim 5
Dependent Claim
49 words
A wall structure as recited in claim 3 wherein said extension has an outermost wall which forms a male spline, a female portion at the rear of said bottom perimeter member into which said male spline projects, and a perimetric seal between said outermost wall and said female portion.
Claim 6
Dependent Claim
58 words
A wall structure as recited in claim 1 wherein said panels extend horizontally in spaced relationship to form vertical joints and wherein said side perimeter members have rear female grooves in confronting relationship across each of said vertical joints, and a vertical joint spline member vertically slidably mounted in said female grooves to close off said vertical joint.
Claim 7
Dependent Claim
32 words
A wall structure as recited in claim 5 together with snap fitting interlocking means connecting said vertical joint spline member to said side perimeter members with means for sealing said vertical joint.
Claim 8
Dependent Claim
75 words
An individual panel as recited in claim 1 wherein the ends of said perimeter members are miter cut to meet and to form miter corners behind said front plate, and wherein each of said perimeter members contains a small pocket with sealant to form sealing lines between said front plate and said perimeter members, and wherein said sealing lines are engaged at said miter corners to provide a complete perimeter seal of said front plate.
Claim 9
Dependent Claim
66 words
A wall structure as recited in claim 1 wherein said panels extend vertically in spaced relationship to form horizontal joints and wherein said top perimeter member of said panel below said horizontal joint has an integral upstanding spline extending across said horizontal joint and adaptably engaged and sealed into a female groove of said bottom perimeter member of another said panel located above said horizontal joint.
Claim 10
Dependent Claim
108 words
A metal plate exterior wall structure comprising a number of individual panels securely fastened to a wall supporting frame system, each of the said panels having a front plate forming the exterior face of said wall structure, one top perimeter member, two side perimeter members and one bottom perimeter member; the improvement comprising at least one continuous horizontal key rib on said top perimeter member having an outwardly flared head portion and a connecting clip rigidly mounted on said wall supporting frame system and having at least one keyway corresponding in shape with said outwardly flared head portion and in which said continuous key rib is relatively slidable.
Claim 11
Dependent Claim
108 words
A metal plate exterior wall structure comprising a number of individual panels securely fastened to a wall supporting frame system, each of the said panels having a front plate forming the exterior face of said wall structure, one top perimeter member, two side perimeter members and one bottom perimeter member; the improvement comprising at least one continuous horizontal key rib on said top perimeter member having an outwardly flared head portion and a connecting clip rigidly mounted on said wall supporting frame system and having at least one keyway corresponding in shape with said outwardly flared head portion and in which said continuous key rib is relatively slidable.
Claim 12
Dependent Claim
46 words
An individual panel as recited in claim 9 wherein a pair of said continuous horizontal key ribs are formed on said top perimeter member, running parallel to said exterior face of said wall structure, each having a horizontal bottom wall integral with said top perimeter member.
Claim 13
Dependent Claim
27 words
An individual panel as recited in claim 10 wherein each of said bottom walls has at least one weep hole for water drainage to a space below.
Claim 14
Dependent Claim
128 words
A metal plate exterior wall structure comprising a number of individual panels securely fastened to a wall supporting frame system, both vertical and horizontal sealed reveal joints being formed between said panels, each individual panel including a front plate and a top perimeter member, two side perimeter members, and one bottom perimeter member, the perimeter members being structurally connected to said front plate and sealed along their perimeters; the improvement comprising an internal horizontal gutter in said top perimeter member, said top perimeter member having a continuous channel below said internal horizontal gutter wherein an enclosed hollow space is formed between said front plate and said continuous channel, at least one hole at the bottom of said internal horizontal gutter for leading condensate into said enclosed hollow space.
Claim 15
Dependent Claim
128 words
A metal plate exterior wall structure comprising a number of individual panels securely fastened to a wall supporting frame system, both vertical and horizontal sealed reveal joints being formed between said panels, each individual panel including a front plate and a top perimeter member, two side perimeter members, and one bottom perimeter member, the perimeter members being structurally connected to said front plate and sealed along their perimeters; the improvement comprising an internal horizontal gutter in said top perimeter member, said top perimeter member having a continuous channel below said internal horizontal gutter wherein an enclosed hollow space is formed between said front plate and said continuous channel, at least one hole at the bottom of said internal horizontal gutter for leading condensate into said enclosed hollow space.
