Abstract
Abstract A method for assembling multi-unit, party wall residential buildings employs fire-resistant structural panels which are manufactured off-site and installed in the structure as completed party walls. The individual units are assembled side-by-side and thereafter the factory-assembled, fire-resistant party wall panels are introduced into the building covering the contiguous walls of the individual units. Satisfactory fire ratings for the resulting buildings can be achieved. The fire-resistant wall sections are fabricated from a frame which is covered with fire-resistant panels on both surfaces and filled with acoustical insulation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
79 words
A method of assembling a multi-unit, party wall building on a foundation comprising the steps of connecting at least one floor deck, vertical side walls and a roof for each said unit and connecting a vertical end wall to the end units of each building, maintaining an opening between the contiguous units above the said foundation, and thereafter installing a fire-resistant party wall between contiguous units by sliding party wall sections downwardly between the roofs of the contiguous units.
Claim 2
Independent Claim
79 words
A method of assembling a multi-unit, party wall building on a foundation comprising the steps of connecting at least one floor deck, vertical side walls and a roof for each said unit and connecting a vertical end wall to the end units of each building, maintaining an opening between the contiguous units above the said foundation, and thereafter installing a fire-resistant party wall between contiguous units by sliding party wall sections downwardly between the roofs of the contiguous units.
Claim 3
Dependent Claim
12 words
The method of claim 1 wherein each unit has two floor decks.
Claim 4
Dependent Claim
38 words
The method of claim 1 wherein each said fire-resistant party wall comprises a section corresponding to the contiguous area between contiguous units for each floor deck and a top section corresponding to the contiguous area between contiguous roofs.
Claim 5
Dependent Claim
36 words
The method of claim 1 wherein each said fire-resistant party wall comprises at least two sections which are abutted along a horizontal seam which is at a level coinciding with at least one said floor deck.

Claim 8
Dependent Claim
27 words
The method of claim 1 wherein each of the said party wall sections comprises an incombustible frame having two layers of fire-resistant sheeting on each surface thereof.
Claim 9
Dependent Claim
24 words
The method of claim 7 wherein each of the said party wall sections has acoustical insulation between the inner layers of said fire-resistant sheeting.
Claim 10
Dependent Claim
28 words
The method of claim 1 wherein a said floor deck is secured to a said fire-resistant party wall section by means of a light gauge sheet metal clip.
Claim 11
Dependent Claim
