Abstract
Abstract A constructional assembly comprising a core part having nonintersecting channels therethrough which cross over each other, the channels being adapted to receive both clamping elements, for detachably interconnecting adjacent constructional assemblies, and also wiring and piping, and the channels extending parallel to side wall surfaces of the core part; at least one load-bearing cover plate which is disposed adjacent a said side wall surface and which is offset in relation to the core part, the core part being less dense than the cover plate and at least one stiffener member which covers a region of the core part which is not covered by a cover plate.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
106 words
A constructional assembly comprising a core part having nonintersecting channels therethrough which cross over each other, the channels being adapted to receive both clamping elements, for detachably interconnecting adjacent constructional assemblies, and also wiring and piping, and the channels extending parallel to side wall surfaces of the core part; at least one load-bearing cover plate which is disposed adjacent a said side wall surface and which is offset in relation to the core part, the core part being less dense than the cover plate and at least one stiffener member which covers a region of the core part which is not covered by a cover plate.
Claim 2
Dependent Claim
106 words
A constructional assembly comprising a core part having nonintersecting channels therethrough which cross over each other, the channels being adapted to receive both clamping elements, for detachably interconnecting adjacent constructional assemblies, and also wiring and piping, and the channels extending parallel to side wall surfaces of the core part; at least one load-bearing cover plate which is disposed adjacent a said side wall surface and which is offset in relation to the core part, the core part being less dense than the cover plate and at least one stiffener member which covers a region of the core part which is not covered by a cover plate.
Claim 3
Dependent Claim
26 words
An assembly as claimed in claim 1 in which each of two opposite side wall surfaces of the core part is provided with a cover plate.
Claim 4
Dependent Claim
18 words
An assembly as claimed in claim 1 in which the core part is formed of a foamed material.
Claim 5
Dependent Claim
21 words
An assembly as claimed in claim 1 in which each cover plate is made of metal or a hard plastics material.
Claim 6
Dependent Claim
72 words
An assembly as claimed in claim 2 in which the stiffener member is U-shaped and has flanges which are respectively disposed in contact with opposite side wall surfaces of the core part, the thickness of said flanges being substantially the same as that of the cover plates, and the length of the flanges being substantially equal to the extent to which the cover plates are offset in relation to the core part.
Claim 7
Dependent Claim
26 words
An assembly as claimed in claim 5 in which a square tube is secured to the outer side of the web of the U-shaped stiffener member.
Claim 8
Dependent Claim
32 words
An assembly as claimed in claim 6 in which a plurality of stiffener members are provided, the stiffener members and cover plates collectively covering all the external surfaces of the core part.
Claim 9
Dependent Claim
37 words
An assembly as claimed in claim 6 in which there are a plurality of said assemblies, the web of a U-shaped stiffener member of one assembly being secured to a U-shaped stiffener member of an adjacent assembly.
Claim 10
Dependent Claim
26 words
An assembly as claimed in claim 8 in which a U-shaped stiffener member of each assembly is secured to a side surface of the square tube.
Claim 11
Dependent Claim
62 words
An assembly as claimed in claim 2 in which the stiffener member is box-shaped, and is disposed between and in contact with the cover plates which cover the opposite side wall surfaces of the core part, the stiffener member having walls whose length is substantially equal to the extent to which the cover plates are offset in relation to the core part.
Claim 12
Dependent Claim
21 words
An assembly as claimed in claim 10 in which the box-shaped stiffener member is strengthened by being secured to a tube.
Claim 13
Dependent Claim
55 words
An assembly as claimed in claim 2 in which the core part is made of a compressible material and is slightly larger than the cover plates, so that when a plurality of said assemblies are assembled together, the cover plates of adjacent assemblies abut each other only when the respective core parts have been compressed.
Claim 14
Dependent Claim
38 words
An assembly as claimed in claim 1 in which the core part and the at least one cover plate are made of the same material, the cover plate having been compacted to be denser than the core part.
