Abstract
This invention relates to a curtainwall system having panels mounted on a grid formed of vertical and horizontal mullions having a planar or flat exterior surface. Each of the panels is provided with a frame formed of hanger sections having a groove facing the interior of the frame. A panel engaging clip has one end inserted in the groove of the hanger frame and the other portion of the clip secured to the grid. The clip urges the hanger against the weatherstripping of the grid to provide an air and dust tight seal. A polyurethane block is mounted in the space between adjacent panels and thereafter a silicone is extruded into the space.
Claims21
A panel for a curtainwall of the type having structural members arranged to form a grid, comprising:
- a glazing sheet for overlaying an opening defined by the grid and having a surface to face the grid, defined as inner sheet surface;
- and
- a closed moisture and dust resistant frame secured on said inner sheet surface and having a groove which is engaged to maintain said frame on the structural members defining the grid, said frame including at least two hanger section having a joint between ends of adjacent said hanger sections, and a moisture and dust resistant seal over portions of said joint to provide said closed moisture and dust resistant frame.
The panel as set forth in claim 6 wherein the glazing sheet is a first glass sheet and further including a second glass sheet in spaced relation to said first sheet to provide a pair of glass sheets and further including a moisture resistant edge seal to prevent moisture ingress between said sheets.
Curtainwall for a structure, comprising:
- a plurality of vertical and horizontal mullions;
- means for interconnecting the structure and said vertical and horizontal mullions to form a grid mounted to the structure;
- a glass panel;
- a frame having a plurality of elongated hanger sections secured directly on surface of said panel facing said grid;
- a plurality of panel clips said clips having a first leg portion connected to a second leg portion wherein the connection between said first and second leg portions has a generally L-shaped configuration.
- means for slideably interconnecting said first portion of each of said clips and a respective portion of said hanger sections;
- and
- means engaging said second portion of each of said clips and moveable relative thereto for detachably mounting said panel clips to said grid to secure said panel in position on said grid.
Curtainwall for a structure, comprising:
- a grid;
- means for mounting said grid to the structure;
- a glazing sheet;
- hanger sections;
- means for securing said hanger sections on surface of said sheet facing said grid to form a frame having a groove;
- a panel clip;
- means for interconnecting said clip and a portion of the groove of said hanger frame;
- and
- means engaging said clip and moveable relative thereto for detachably mounting said panel clip to said grid to secure said panel in position.
Curtainwall for a structure, comprising:
- a grid having panel supporting surfaces;
- means for mounting said grid to the structure;
- a panel;
- hanger frame having a periphery forming a moisture and dust seal;
- means for securing said frame on surface of said panel facing said grid;
- weatherstripping between said hanger frame and panel supporting surface of said grid;
- a panel clip having one portion engageable with said hanger frame;
- and
- means for detachably securing said panel clip to said grid, said detachably securing means includes means acting on said panel clip and said grid to bias said hanger frame against said weatherstripping.
Curtainwall for a structure, comprising:
- a grid having an engaging foot and panel supporting member;
- means for mounting said grid to the structure;
- a glazing panel;
- a hanger frame having a groove facing interior of said frame;
- means for securing said hanger frame on said surface of said panel facing said grid;
- a clip having a C-shaped portion having an outer leg inserted in the groove of said hanger frame and other leg overlaying surface of said grid facing the structure and a member engageable with said panel engaging foot.
