Abstract
Abstract A device for interconnecting two adjacent spaced plates forming at least part of a wall, comprises a cover plate arranged on one side of the plates, a plurality of monobloc connectors arranged on the opposite side of the plates and a pair of channel members for each connector. The connectors are each in the form of a central member provided at each end with transverse flanges extending from opposite sides of the central member. The connectors each have a projection extending beyond the flanges into the space between the plates, the flanges and the projection defining between them a pair of opposed grooves. Each groove receives a limb of a channel member. Each projection is formed with a slot which divides the projection into two parts and receives and holds a complementary shaped rib on the cover plate. The minimum width of each groove is less than the thickness of its respective limb so that when the limbs are arranged in the grooves, the two parts of the projection are urged towards each other to grip the rib.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
220 words
A device for interconnecting two adjacent, spaced plates lying in substantially the same plane and forming at least part of a wall, comprising a cover plate positioned on a first side of the plates and having surfaces for engaging a first side surface of each plate and a rib extending into the space between the plates, a connector positioned on the opposite side of the plates and having a central web provided at one end with a pair of transverse flanges extending from opposite sides of the web, and a projection extending from the flanges into the space between the plates, the projection being formed at its free end with a slot which divides the projection into two parts and receives said rib, the projection and flanges defining between them two opposed grooves, and a pair of channel members arranged one on eaCh side of the connector, one limb of each channel member engaging the second side surface of a plate and extending inwardly towards the connector, the free end of each limb engaging in a groove of the connector, the minimum width of each groove being less than the thickness of its respective limb so that when the limbs are arranged in the grooves, the two parts of the projection are urged towards each other to grip the rib.
Claim 2
Independent Claim
220 words
A device for interconnecting two adjacent, spaced plates lying in substantially the same plane and forming at least part of a wall, comprising a cover plate positioned on a first side of the plates and having surfaces for engaging a first side surface of each plate and a rib extending into the space between the plates, a connector positioned on the opposite side of the plates and having a central web provided at one end with a pair of transverse flanges extending from opposite sides of the web, and a projection extending from the flanges into the space between the plates, the projection being formed at its free end with a slot which divides the projection into two parts and receives said rib, the projection and flanges defining between them two opposed grooves, and a pair of channel members arranged one on eaCh side of the connector, one limb of each channel member engaging the second side surface of a plate and extending inwardly towards the connector, the free end of each limb engaging in a groove of the connector, the minimum width of each groove being less than the thickness of its respective limb so that when the limbs are arranged in the grooves, the two parts of the projection are urged towards each other to grip the rib.
Claim 3
Dependent Claim
52 words
A device according to claim 1, wherein said connector and a channel member, on at least one side the connector are shorter than the length of the cover plate to permit assembly and dismantling of the device by sliding the connector on and off the channel member lengthwise of the cover plate.
Claim 4
Dependent Claim
50 words
A device according to claim 1, wherein the channel members are formed as a plurality of separate parts, the parts being located at spaced positions over the length of the space between the plates, the rib of the cover plate being continuous over the whole length of the cover plate.
Claim 5
Dependent Claim
46 words
A device according to claim 1, wherein the surfaces of the cover plate engaging the first surface of each plate are provided with grooves, a flexible packing being provided in the grooves, said flexible packing having a surface for engaging said first surface of the plate.
Claim 6
Dependent Claim
21 words
A device according to claim 1, wherein the projection carries outwardly extending arms, each arm engaging the edge of a plate.
Claim 7
Dependent Claim
28 words
A device according to claim 1, wherein the projection has side surfaces which are divergent with their outer ends wider apart than their inner width between said surfaces.
Claim 8
Dependent Claim
31 words
A device according to claim 1, wherein ribs are provided at the free ends of the flanges, said ribs engaging in complementary recesses formed in said limbs of the channel members.
Claim 9
Independent Claim
234 words
A device for interconnecting two adjacent, spaced plates lying in substantially the same plane and forming at least part of a wall, comprising a cover plate positioned on a first side of the plates and having a pair of surfaces, each surface engaging a first side surface of a plate adjacent the space between the plate and a rib extending into the space between the plates, a plurality of monobloc connectors positioned on the opposite side of the plates, each connector having a central web provided at each end with transverse flanges extending from opposite sides thereof and a projection extending into the space between the plates, the projection being formed at its free end with a slot which divides the projection into two parts and receives a portion of the rib, the projection and flanges defining between them a pair of opposed grooves, and a pair of channel members for each connector arranged one on each side of the connector, one limb of each channel member engaging the second side surface of a plate and extending inwardly towards the connector, the free end of each limb engaging in a groove of the connector, the minimum width of each groove being less than the thickness of its respective limb so that when the limbs are arranged in the grooves, the two parts of the projection are urged towards each other to grip the rib.
