Abstract
Abstract A joint for use in a partition wall building assembly and method in which abutting edge surfaces forming the joint are provided with rigid self supporting fibres projecting substantially normally from the surfaces and intermeshed to resist shear movement between the surfaces. The top and bottom surfaces of a partition wall panel are provided with the projecting fibres which intermesh with fibres on the ceiling and floor surfaces to hold the panel in position. The ceiling and floor surfaces are relatively movable vertically to clamp the panel and ensure complete intermeshing of the fibres. The length and density of the fibres is such that shear movement is substantially prevented.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
191 words
A method of erecting a partition wall in a building, comprising the steps of providing a plurality of substantially rigid, substantially straight self-supporting fibres on the top and bottom horizontal edge surfaces of the panel so that the fibres project from the edge surface substantially normally thereto; providing a plurality of substantially rigid, substantially straight self-supporting fibres in a lower band along the floor surface of the building and in an upper band along the ceiling surface of the building so that said fibres on the floor and ceiling surfaces project substantially normally thereto; aligning the panel between the upper and lower bands of fibres; moving the floor and ceiling surfaces relative to one another so as to clamp the panel between the floor and ceiling surfaces and cause the fibres on the top edge surface of the panel to intermesh with the fibres on the ceiling surface and the fibres on the bottom edge surface of the panel to intermesh with the fibres on the floor surface, whereby shear movement between the top and bottom edge surfaces of the panel and the ceiling and floor surfaces, respectively, are substantially prevented.
Claim 2
Independent Claim
191 words
A method of erecting a partition wall in a building, comprising the steps of providing a plurality of substantially rigid, substantially straight self-supporting fibres on the top and bottom horizontal edge surfaces of the panel so that the fibres project from the edge surface substantially normally thereto; providing a plurality of substantially rigid, substantially straight self-supporting fibres in a lower band along the floor surface of the building and in an upper band along the ceiling surface of the building so that said fibres on the floor and ceiling surfaces project substantially normally thereto; aligning the panel between the upper and lower bands of fibres; moving the floor and ceiling surfaces relative to one another so as to clamp the panel between the floor and ceiling surfaces and cause the fibres on the top edge surface of the panel to intermesh with the fibres on the ceiling surface and the fibres on the bottom edge surface of the panel to intermesh with the fibres on the floor surface, whereby shear movement between the top and bottom edge surfaces of the panel and the ceiling and floor surfaces, respectively, are substantially prevented.
Claim 3
Dependent Claim
41 words
A method as claimed in claim 1, in which the density of the fibres is within the range 30,000 to 70,000 fibres per square inch and the length of the fibres is within the range 0.06 to 0.10 of an inch.
Claim 4
Dependent Claim
39 words
A method as claimed in claim 2, including the further step of interposing a backing strip of resilient material between the fibres and each edge surface of the panel and between the fibres and the floor and ceiling surfaces.
Claim 5
Dependent Claim
147 words
A method as claimed in claim 3, including the further steps of providing a plurality of substantially rigid, substantially straight self-supporting fibres on the vertical side edge surfaces of the panel so that said side fibres project substantially normally from said side edge surfaces; providing a plurality of substantially rigid, substantially straight self-supporting fibres in vertical bands along vertical said supporting surfaces adjacent the panel so that said fibres project substantially normally from said vertical side supporting surfaces; aligning the panel between the vertical bands of fibres; and moving the side supporting surfaces relatively towards one another to clamp the panel therebetween and cause the fibers on the vertical side edge surfaces of the panel to intermesh with the fibres on the vertical side supporting surfaces, whereby shear movement between the vertical side edges surfaces of the panel and the vertical side supporting surfaces is substantially prevented.
