Abstract

Abstract Fire-retardant walls composed of construction elements, especially for use in shipbuilding, in which wall plates have each two covering panels. One or several fire-retardant layers are located between the two covering panels. The vertical edges of the covering panels are shaped into profiles and provided with slits for the insertion of hooks located on vertical supports.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 278 words
A fire-resistant wall for ships and assemblable from construction components comprising, in combination, wall plate means having two covering panels; fire-resistant means between said covering panels, said covering panels having vertical edges shaped into integral profiles and having slits; vertical support means for supporting said wall plate means, said vertical support means being substantially less in width than said wall plate means, said profile shaped vertical edges being angularly bent and directed inward toward the interior of said wall plate means for contacting directly corners of said vertical support means, said angularly directed vertical edges for contacting said vertical support means being spaced by a distance substantially equal to the width of said vertical support means; hook means on said vertical support means and inserted into said slits, said vertical support means comprising multi-cornered pipe-shaped means, each surface of said pipe-shaped means having a predetermined number of said hook means, said wall plate means being erectable at varying angles to a neighboring wall plate means, the central axis of all said wall plate means intersecting at the center point of said multi-cornered pipe-shaped means; said fire-resistant means surrounding substantially said vertical pipe-shaped means; profile rail means open on one side and covering the free edges of said vertical support means; said rail means being spaced from said vertical support means and spanning the space between angularly inward directed vertical edges of adjacent covering panels, the outer surface of said rail means being substantially flush with the outer surface of said covering panels; said rail means forming an internal space with said angularly inward directed vertical edges and said vertical support means; said fire-resistant material filling said internal space.
Claim 2
Dependent Claim 278 words
A fire-resistant wall for ships and assemblable from construction components comprising, in combination, wall plate means having two covering panels; fire-resistant means between said covering panels, said covering panels having vertical edges shaped into integral profiles and having slits; vertical support means for supporting said wall plate means, said vertical support means being substantially less in width than said wall plate means, said profile shaped vertical edges being angularly bent and directed inward toward the interior of said wall plate means for contacting directly corners of said vertical support means, said angularly directed vertical edges for contacting said vertical support means being spaced by a distance substantially equal to the width of said vertical support means; hook means on said vertical support means and inserted into said slits, said vertical support means comprising multi-cornered pipe-shaped means, each surface of said pipe-shaped means having a predetermined number of said hook means, said wall plate means being erectable at varying angles to a neighboring wall plate means, the central axis of all said wall plate means intersecting at the center point of said multi-cornered pipe-shaped means; said fire-resistant means surrounding substantially said vertical pipe-shaped means; profile rail means open on one side and covering the free edges of said vertical support means; said rail means being spaced from said vertical support means and spanning the space between angularly inward directed vertical edges of adjacent covering panels, the outer surface of said rail means being substantially flush with the outer surface of said covering panels; said rail means forming an internal space with said angularly inward directed vertical edges and said vertical support means; said fire-resistant material filling said internal space.
Claim 3
Dependent Claim 34 words
The fire-resistant wall as defined in claim 1 including grip-spring tensioning means for clamping said vertical support means between a floor and ceiling, at least one of said grip-spring tensioning means having a spring.
Claim 4
Dependent Claim 33 words
The fire-resistant wall as defined in claim 1 including cross strap means along the open sides of said profile rail means, said cross strap means engaging said hook means on said support means.
Claim 5
Dependent Claim 25 words
The fire-resistant wall as defined in claim 1 including means generating foam when exposed to heat coated on adjoining edges of said wall plate means.
Claim 6
Dependent Claim 21 words
The fire-resistant wall as defined in claim 1 including means generating foam when exposed to heat coated on said support means.
Claim 7
Dependent Claim 85 words
The fire-resistant wall as defined in claim 1 including grip-spring tensioning means for clamping said vertical support means between a floor and ceiling, at least one of said grip-spring tensioning means having a spring; cross strap means along the open sides of said profile rail means and engaging said hook means on said support means; fire-resistant material filling said internal space; and foam generating means coated on adjoining edges of said wall plate means and said support means for generating foam when exposed to heat.
