Modular framework support systems
The present invention relates to modular framework support systems. In particular, it relates to framework support systems of the non-penetrative type particularly used for supporting heating and ventilating apparatus and other service and plant apparatus on a roof of a building. The application describes a support ( 10 ) for a modular framework system, the support comprising a planar foot ( 11 ) comprising a socket ( 12 ) having a substantially rectangular cross-section with a long axis and a short axis. The socket has a base and an opening. The socket is provided with one or more elongate ribs ( 25 ) between the base and the opening and extending into the socket. The socket further comprises a projection ( 20 ) extending upwardly from the base, the projection having a spine ( 21 ) aligned with the long axis of the socket. Preferably, each rib ( 25 ) has a stepped configuration such that an operatively lower portion of the rib extends further into the socket than an operatively upper portion of the rib.
1. A support for a modular framework system, the support comprising:
a planar foot;
a socket extending upwardly from the foot and having a substantially rectangular cross-section formed by opposed longer walls and opposed shorter walls extending upwardly from the foot, wherein the opposed longer walls define a long axis of the socket and the opposed shorter walls define a short axis of the socket,
wherein the socket has a base and an opening and is provided with one or more elongate ribs between the base and the opening and extending into the socket,
wherein each rib has a stepped configuration such that an operatively lower portion of the rib extends further into the socket than an operatively upper portion of the rib, and
wherein the socket further comprises a projection extending upwardly from the base of the socket substantially the same height as the height of the longer and shorter walls, the projection having a spine aligned with the long axis of the socket.
2. A support as claimed in claim 1 wherein the spine includes at least one pair of fingers extending laterally therefrom, one finger on each side of the spine.
3. A support as claimed in claim 2 wherein each finger has a 90 degree bend.
4. A support for a modular framework system, the support comprising:
a planar foot;
a socket extending upwardly from the foot and having a substantially rectangular cross-section formed by opposed longer walls and opposed shorter walls extending upwardly from the foot, wherein the opposed longer walls define a long axis of the socket and the opposed shorter walls define a short axis of the socket, wherein the socket has a base and an opening and is provided with one or more elongate ribs between the base and the opening and extending into the socket, and wherein the socket further comprises a projection extending upwardly from the base of the socket substantially the same height as the height of the longer and shorter walls, the projection having a spine aligned with the long axis of the socket; and
a channeled strut inserted in the socket of the support, wherein the strut has a U-shaped cross-section and the projection extends into the U-shaped cross-section to provide support and alignment to the strut.
5. A support as claimed in claim 4 wherein the spine includes at least one pair of fingers extending laterally therefrom, one finger on each side of the spine.
6. A support as claimed in claim 5 wherein each finger has a 90 degree bend.
