Abstract

Abstract In a modular building having modules abutting each other to form a living unit, the roofing for the modules is sealed by providing a receptacle on the roof of one of the modules adjacent to the juncture between two modules, overlapping roof membranes within the receptacle, sealing the overlapping joint of the membranes within the receptacle with sealing cement in the receptacle, and sealing the roof membranes at edges of the modules. In a preferred embodiment, the modules have an opening in a wall next to the roof, and this opening is sealed by a waterproof sheet which is affixed to the roof and extends from the roof over the wall opening. This sealing sheet is provided on the module before it is assembled with other modules to form a living unit in order to protect the module against rain during storage and transport of the module. At one edge of the roof of the module which is the preferred embodiment, a mansard structure is affixed to the roof, and the roof membranes extend over the mansard structure and are sealed at the edge of the mansard structure by means of a sealing strip.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 188 words
In a modular building having first and second modules abutting each other, roofing for said modules comprising a first roofing membrane on the roof of said first module, a second roofing membrane on the roof of said second module, a mansard structure suspended from the roof of said first module at an edge thereof and projecting laterally outward from said roof, a channel affixed to the roof of one of said modules adjacent the juncture between said modules, said membranes overlapping each other within said channel and being affixed to said channel, sealing cement in said channel sealing the overlapping joint between said membranes, and means sealing said first membrane to said mansard at a place where said first membrane overlaps said mansard, said mansard comprising a frame having a panel on the top thereof over which said first membrane extends, and shingles on an exterior side thereof for protection and decoration, said sealing means comprising a strip affixed to said panel and lapping over both said panel and said shingles at a juncture between the same, and cement sealing the joint between said strip and said membrane.
Claim 2
Dependent Claim 188 words
In a modular building having first and second modules abutting each other, roofing for said modules comprising a first roofing membrane on the roof of said first module, a second roofing membrane on the roof of said second module, a mansard structure suspended from the roof of said first module at an edge thereof and projecting laterally outward from said roof, a channel affixed to the roof of one of said modules adjacent the juncture between said modules, said membranes overlapping each other within said channel and being affixed to said channel, sealing cement in said channel sealing the overlapping joint between said membranes, and means sealing said first membrane to said mansard at a place where said first membrane overlaps said mansard, said mansard comprising a frame having a panel on the top thereof over which said first membrane extends, and shingles on an exterior side thereof for protection and decoration, said sealing means comprising a strip affixed to said panel and lapping over both said panel and said shingles at a juncture between the same, and cement sealing the joint between said strip and said membrane.
Claim 3
Dependent Claim 27 words
The roofing as claimed in claim 1 in which said channel has tapered side portions forming ramps under said membranes where said membranes lead into said channel.
Claim 4
Dependent Claim 21 words
The roofing as claimed in claim 2 in which said channel and said tapering side portions are integral with each other.
Claim 5
Dependent Claim 50 words
The roofing as claimed in claim 1 in which at least one of said modules has an opening at the juncture between said modules, and further including a flexible waterproof sheet affixed to said channel and extending therefrom over said opening for covering said opening before said modules are interconnected.
Claim 6
Dependent Claim 24 words
The roofing as claimed in claim 4 in which said sheet is affixed to said roof of said first module only at said channel.
