`ABSTRACT
`In a glass-metal structure for a front wall or a roof of a
`building, comprising a metal framework and glass pan
`els, the framework is formed of hollow elongated main
`frame sections and hollow elongated crossbar frame
`sections extending transversally of the main frame sec
`tions. Cover plates overlapping the edges of the glass
`panels are screwed by bolts to the frame sections. Each
`frame section and each cover plate is provided with
`anchoring grooves receiving sealing strips. Each frame
`section has gutters for condensed water and grooves for
`percolating waters. Each crossbar frame section has a
`main hollow chamber and an additional hollow cham
`ber formed between the gutters of the crossbar frame
`section.

`
`METAL-GLASS STRUCTURE FOR A FRONT
`WALL OR A ROOF
`
`5
`
`15
`
`BACKGROUND OF THE INVENTION
`The present invention relates to a metal-glass struc
`ture for a front wall or a roof of a building.
`The metal-glass structure of a front wall or a roof of
`the type under consideration is comprised of a metal
`framework, the flats of which are covered with glass
`panels. The metal framework includes a plurality of
`main frame sections or profiles at the side of the build
`ing and a plurality of crossbar frame sections or profiles
`extended transversely of the main profiles and covered
`at their outer sides with cover frame sections which are
`connected by bolts to the main frame sections or the
`crossbar frame sections. The main frame sections, cross
`bar frame sections and cover frame sections have an
`choring grooves for sealing strips supported at the
`20
`edges of the glass panels. The main and crossbar frame
`sections are also provided with gutters for condensed
`water and grooves for percolating waters. The main
`frame sections are normally hollow profiles.
`A conventional front wall-or-roof structure is de
`25
`picted in FIG. 1. The crossbar frame section of the
`framework of this structure has only one hollow cham
`ber, the upper wall of which forms two grooves for
`collecting percolating water. Percolating water is col
`lected between the edges of the glass panels and the 30
`sealing strips provided in the cover frame sections and
`should be drained off therefrom through the grooves
`formed in the main frame sections. In order to provide
`a smooth transition between the percolating water
`receiving grooves of the crossbar frame sections and the
`35
`grooves of the main frame sections the latter should be
`coped in the region of the butt between the main frame
`section and the crossbar section. Furthermore the shape
`of the crossbar frame sections must be adjusted to the
`shape of the main frame sections, and the upper walls of 40
`the hollow chambers of the crossbar frame sections
`should extend up to the region of the corresponding
`water-receiving grooves of the main frame sections. If
`clogging takes place in the grooves of the main profiles
`percolating waters flow into the hollow chambers of 45
`the crossbar profiles. However, leakage can occur at the
`connections of the crossbar profiles.
`Main frame sections or profiles of conventional front
`wall or roof structures have gutters for condensed wa
`ter, which is collected at the edges of the glass panels
`50
`and flows into the gutters. The botton wall of the hol
`low chamber of each crossbar frame section extends in
`the region of such a gutter of the main frame section so
`that in case of clogging in the gutter of the main frame
`section condensed water can flow into the hollow
`chamber of the crossbar frame section.
`SUMMARY OF THE INVENTION
`It is an object of the present invention to provide an
`improved front wall or a roof structure.
`60
`It is another object of this invention to provide a front
`wall or a roof structure in which, for discharging perco
`lating waters from the grooves of the crossbar frame
`sections into the grooves of the main frame sections in
`the regions of the butts therebetween a coping of the
`walls of the grooves of the main frame sections is
`avoided and, in case of obstruction in a drain water
`system for condensed waters and percolating waters,
`
`4,638,613
`2
`the penetration of waters into the hollow chambers of
`the crossbar frame sections is avoided.
`These and other objects of the invention are attained
`by a metal-glass structure for a front wall or a roof,
`comprising a metal framework having flats covered
`with glass panels, said framework including a plurality
`of main frame sections at a building side; a plurality of
`crossbar frame sections extending transversely of said
`main frame sections; a plurality of cover profiles
`0 screwed to said main and crossbar frame sections and
`extending over edges of said glass panels, said main
`frame sections, said crossbar frame sections and said
`cover profiles having anchoring grooves; and sealing
`strips received in said anchoring grooves and supported
`on the edges of the glass panels, said main and crossbar
`frame sections each enclosing a hollow chamber and
`being provided with gutters for condensed water and
`grooves for percolating water, each groove for perco
`lating water in each crossbar frame section having a
`bottom wall which extends up to an upper edge of a
`respective groove for percolating water of an adjacent
`main frame section and is supported against said upper
`edge, each crossbar frame section having a main hollow
`chamber and an additional hollow chamber above said
`main chamber, said additional chamber being positioned
`between two gutters for condensed water and having a
`bottom wall being flush with bottom walls of said gut
`ters, the bottom wall of each additional hollow chamber
`and the bottom walls of said two gutters of each cross
`bar frame section being supported on an upper longitu
`dinal edge of a respective gutter for condensed water of
`the adjacent main frame section.
`The construction of the front wall or the roof accord
`ing to the present invention ensures that the separation
`of the draining of condensed water from the draining of
`percolating water is such that main frame sections
`should be not provided with coping elements. It is fur
`ther ensured that in case of stagnation of water in the
`gutters or water-receiving grooves no water would
`drain off into the hollow chambers of the main or cross
`bar frame sections, and a waterproof structure at the
`connections of the main and crossbar frame sections
`with other structural components of the front wall or
`the roof would be warranted.
`Each main frame section may have two longitudinal
`grooves for percolating water, said longitudinal
`grooves being defined by outer profiled wall portions
`which form the anchoring grooves for said sealing
`strips, each crossbar frame section having at least two
`anchoring grooves for the sealing strips, said two an
`choring grooves having the same height as that of said
`grooves for percolating water, said anchoring grooves
`for the sealing strips having walls which in a region of
`overlapping are supported on the anchoring grooves of
`the adjacent main frame section.
`The gutters for condensed water of each main frame
`section may each have a bottom wall which is flush
`with a bottom wall of each groove for percolating
`water of said main frame section, the bottom walls of
`said gutters and the bottom walls of said grooves form
`ing an upper wall of a hollow chamber of each main
`frame section.
`Each main frame section may be formed with a cen
`tral web extended upwardly from the hollow chamber
`thereof, said web being formed with a threaded opening
`and defining said two grooves for percolating water.
`Each crossbar frame section may be formed with a
`central profiled portion extended upwardly from said
