Abstract
Abstract A protective peripheral cornice of a building which cornice is an equal angle broad flanged beam inserted between the top of the wall and the end section of the ceiling. Such beam is made of light material which is totally enveloped in a metal sheet except for two interruptions in each of which the sheet is replaced by bridgelike means of insulating plastic material which extend for about 1/2 the panel thickness; one of said interruptions being located across the horizontal median plane of the roof panel while the other is located across the vertical median plane of the wall panel. Such interruptions having thus the function of thermal insulations or thermal barriers.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
188 words
A protective peripheral cornice of a building wherein the walls and the top roof are both formed with modular panels of common dimensions a cornice that is an equal angle broad flanged beam is inserted between the top of the wall and the end section of said roof which cornice with its inner surface of its vertical flange covers the end of the ceiling and with its inner surface of its horizontal flange covers the terminal section of the ceiling; while the outer surface of its horizontal flange covers the top surface of the wall and projects from the latter for about 1/4 of the wall thickness while the outer surface of the vertical flange is exposed to the atmosphere, said cornice being made of light material which is totally enveloped in a metal sheet except for two interruptions where the sheet is replaced by bridgelike means of insulating plastic material which extend for about 1/2 the panel thickness; one of said interruptions being located across the horizontal median plane of the ceiling panel while the other is located across the vertical median plane of the wall panel.
Claim 2
Dependent Claim
188 words
A protective peripheral cornice of a building wherein the walls and the top roof are both formed with modular panels of common dimensions a cornice that is an equal angle broad flanged beam is inserted between the top of the wall and the end section of said roof which cornice with its inner surface of its vertical flange covers the end of the ceiling and with its inner surface of its horizontal flange covers the terminal section of the ceiling; while the outer surface of its horizontal flange covers the top surface of the wall and projects from the latter for about 1/4 of the wall thickness while the outer surface of the vertical flange is exposed to the atmosphere, said cornice being made of light material which is totally enveloped in a metal sheet except for two interruptions where the sheet is replaced by bridgelike means of insulating plastic material which extend for about 1/2 the panel thickness; one of said interruptions being located across the horizontal median plane of the ceiling panel while the other is located across the vertical median plane of the wall panel.
Claim 3
Dependent Claim
99 words
A cornice as claimed in claim 1 wherein said bridgelike longitudinal means comprises a flat desk which extends for the same lenght as said cornice the longitudinal axis of which deck lying in the mean centerline of the panel thickness at the end thereof said deck being provided along its sides with symmetrical clamping edges for engaging corresponding clamping edges of the interrupted enveloping sheet of said broad flanged beam and making with them a pair of folded seams for each of said interruptions the distance between the seams of each interruption being about one half the panel thickness.
Claim 4
Dependent Claim
58 words
A cornice as claimed in claim 1 wherein the inner and outer surface top sections of said wall are both covered by a pair of doubled metal sheet sections which extend downwards from the metal sheet by which the horizontal outer flange of said beam is enveloped; said doubled metal sheet sections being adherent to said building wall.
