Abstract

An aluminium lighting column includes an access opening and an external strengthening clamp which is dimensioned to extend around and encircle the column with its internal face in close contact with the opposed face of the column and includes a side opening 14 which is dimensioned and positioned to at least partially overlie the access opening of the column. The clamp comprises a plurality of separable arcuate segments 1a, 1b and means for assembling these segments into a circular array for location about the outer face of the column.

Description

STREET LIGHTING COLUMNS
This invention relates to an external clamp for strengthening an aluminium lighting column at a location where an opening is formed in the column for access to the column interior.
Conventionally an aluminium street lighting column comprises an elongate aluminium tube which includes one or more openings to provide access to the column interior for maintenance or repairs to cabling and other parts boated within the column interior. Any such opening is necessarily of sufficient width and height to provide good access to the column interior and is conventionally olosed by a hinged or removable door. The presence of any such access opening produces areas of weakness within the column which have in the past been compensated for by, for example, providing an internal sleeve whioh is forced under pressure during a manufacturing process into the interior of the column in the region of the or each access opening and which includes an opening which coincides with the respective access opening of the column.
The provision of these internal sleeves is expensive and at times difficult to position accurately within the column.
Their presence also has effect of producing internal space within a column.
Alternative methods have included welding a section of a tube over the or each area of weakness, and welding a section into the door opening to close the same. Although each of these known procedures leads to an increase in column wall thickness, the welding process will itself weaken the aluminium of the column in the heat affected zone by some 40%.
The welding process would also make the structure in the heat affected zone prone to failure through fatigue.
A lighting column is typically supported in an upright position by embedding its lower end in the ground or by locating the column lower end in an upstanding tubular section of a ground embedded base plate. In the past such an upstanding tubular section extends upwardly towards but not over any access opening of the lighting column.
According to the present invention in one aspect there is provided a lighting column which includes an access opening and an external clamp which is dimensioned to extend around and encircle the column with its internal face in close contact with the opposed face of the column and includes a side opening which is dimensioned and positioned to at least partially overlie the access opening of the column, the clamp comprising a plurality of separable arcuate segments and means for assembling these segments into a circular array for location about the outer face of the column.
In a preferred embodiment the clamp comprises two generally semi-circular segments each of which includes an upstanding rib alongside each of its two upstanding side edges, each rib including means for enabling the two segments to be connected together about the outer surface of the column.
Each clamp segment may include a plate which projects at right angles from its lower edge and which on assembly of the clamp defines with the plate(s) of the other segment(s) an annular base plate for the clamp.
At least one clamp segment may include an upstanding rib or indent which co-operates with a complimentary indent or rib formed in the external surface of the column to assist torsional forces imposed on the column during use.
The side opening of the clamp may be covered by a vertically slideable door.
Security bolts may be provided to secure the assembled clamp to the column.
Each clamp segment may include one or more gussets positioned between the upstanding wall and base plate sections of the segment.
The invention will now be described by way of example only with references accompanying diagrammatic drawings in which: Figure 1 is an isometric view of a first embodiment of a clamp in accordance with the invention; Figure 2 is a partially exploded isometric view of the clamp illustrated in Figure 1; Figure 3 is a plan view from above of the clamp illustrated in Figures 1 and 2; and Figures 4 and 5 are respectively a side view and a plan view from above of an alternative clamp in accordance with the invention.
The clamp illustrated in Figures 1 to 3 of the drawings comprises two separable semi-circular segments (1) each of which includes an upstanding collar section (3) and a base plate section (5) which projects generally radially from the lower edge of the respective column section. As will be seen from Figures 1 to 3, two segments together define an annular clamp for the pcsitions about the outer surface cf a lighting column (nct shown) Each semi-circular clamp segment (1) includes an upstanding rib (7a/7b) extending alongside each of its side edges (9) Each rib 7a is formed with a lip (9a) which locates within a recess (ha) formed in the adjoining rib (7b) . Threaded through holes (13) extend through the ribs (7a, 7b) to receive bolts to connect the clamp segments (1) tightly together.
One collar section (3) of the two clamp segments (1) includes an access opening (14) which in use at least partially overlies an access opening of a lighting column about which the clamp is to be fitted.
Gussets (15) extend between the column and base section of each clamp segment to add strength to the clamp when assembled to prevent bending of the base plate sections relative to the column sections.
Slotted holes 17 are provided in the base plate (5) to enable the assembled clamp to be connected to upstanding bolts protruding from the upper surface of ground embedded supporting structure (not shown) The clamp illustrated in Figures 4 and 5 comprises two separable collar sections (19) similar to the collar sections (3) of Figures 1 to 3, but no base plate section. This clamp is primarily for use with ground embedded lifting columns.
S
It would be appreciated that the foregoing is merely exemplary of external clamps for strengthening lightened columns and that modifications can readily be made thereto without departing from the true scope of the invention as set out in the appended claims.
