Description

Improvements in and Relating to Structural Support Systems
Field of the Invention
The present invention relates to structural support systems for conservatories, to conservatory structures constructed using the same and to methods of construction of structural support systems for conservatories.
Background to the Invention
A structural support system can be used in constructing large conservatories that require structural support in addition to that provided by the usual conservatory elements. Where in such a structural support system a hollow rafter beam needs to be attached to a hollow column beam the rafter is mitred to fit and a steel splice plate is located inside and between the rafter and column, and is bolted to both. An elongate slot has to be made in the side wall of the column beam for the splice plate to fit. When so attached the rafter is capable of minor movement relative to the column arising partly from the clearance space around the bolts. This means the eventual structure is less able to cope with external forces .
It is an aim of preferred embodiments of the present invention to obviate or overcome a disadvantage of the prior art, whether referred to herein or otherwise.

Suitably, the end plate comprises means for retaining at least one bolt in a hole through the end plate. Suitably, the means for retaining at least one bolt comprises a holding plate in a slot in the end plate.
Suitably, the end plate is of generally U-shaped cross section. Suitably, the end plate has an end, a first limb depending therefrom and a second limb depending therefrom.

Suitably, the end of the second beam is mitred to fit to the first beam at a desired angle.
Suitably, the first beam is a column beam and the second beam is a rafter beam.
According to the present invention in a second aspect, there is provided a conservatory structure comprising a structural support system at least part of which is according to the first aspect of the present invention.
According to the present invention in a third aspect, there is provided a method of assembly of at least part of a structural support system, the method comprising the steps of providing a first beam, providing an end plate at the end of a second beam at least partly closing the end of the second plate and securing the first and second beams together via the end plate thereby to clamp the first beam to the second beam.
Suitably, the structural support system is according to the first aspect of the present invention.

Description of the Preferred Embodiments
Referring to Figure 1 of the drawings that follow, there is shown a structural support system 2 for a conservatory structure, the structural support system comprising vertical hollow column beams 6, hollow rafter beams 8 and a hollow ridge beam 10. Referring to Figure 2 of the drawings that follow, the structural support system 2 at least partly supports conservatory elements 12 such as glazing panels and extruded bars as is well known in the art.
Referring to Figures 3 and 4 of the drawings that follow there is shown one of the column beams 6 attached to one of the rafter beams 8 using an end plate 14, which is shown in Figures 5 and 6 of the drawings that follow. End plate 14 is of a generally U-shaped cross-sectional shape with first and second limbs 16, 18 and a generally rectangular end 20. The rectangular end 20 has four holes
22 therethrough for receiving bolt fixing means 24 (see
Figures 3 and 4) . On the interior of end plate 14 are recesses 26 aligned with the holes 22 to hold heads of the bolts 24 captive therein to assist in assembly as described below. Aligned slots 28 are provided in the interior of end plate 14 to receive a holding plate 30. Referring again to Figures 5 and 6 further bolt fixing means 32 are used in the side of rafter beam 8 to secure the end plate 14 thereto.
End plate 14 is an aluminium extrusion of substantially constant cross-section with the exception of the holes 22 drilled therethrough (see below) for the bolt fixing means 24.
Referring to Figure 7 of the drawings that follow, a method of assembly of part of a space frame is described.
To assemble the column beam 6 to the rafter beam 8, in step 100 the square ends of each are mitred to the required angle for mutual alignment. In step 101 the end plate is mitred to the required angle, here approximately 30° so it can be inserted in the end of rafter column 8 and its end lie flush therewith. In step 102 bolts 34 are inserted into the holes 22 in the end thereof and holding plate 40 is slid into slots 28 to prevent the bolts 34 from falling out subsequently. Recesses 26 holt the heads of bolt 34 captive so that they can be secured (see below) . In step 104 end plate 14 is inserted into the otherwise open end of rafter beam 8 and is a sliding fit therein. The end plate 14 is inserted until its end 20 is aligned and flush with the end of rafter beam 8. In step 106 holes are drilled in both side walls of rafter beam 8 and therefore through limbs 16, 18. In step 108 bolts 34 are passed through each of the holes from the exterior of one side wall of rafter beam 8 and through the rafter beam 8 to the exterior of the other side wall thereof and secured with corresponding nuts . In step 110 holes aligned with bolts 34 are drilled in a side wall of column beam 6 to which the rafter beam is to be attached. In step 112 the bolts 34 are inserted through the holes in column beam, nuts applied and tightened through the open upper end of column beam 6.
The exposed bolt ends may be covered with cappings to obscure these from view and other aesthetic additions can be made (step 114) .
It will be appreciated by those skilled in the art that by having the first (column) and second (rafter) beams 6, 8 effectively clamped together rather than simply being secured relative to a steel plate the whole structure moves when stressed thus spreading the load better.
It will be appreciated by those skilled in the art that the method of assembly described above can be carried out in a variety of different orders .
Referring to Figure 8 of the drawings that follow there is shown a hip connection to an eaves beam comprising a column beam 60 of rectangular cross-section to three sides of which beams 62and 66, as well as rafter beam 64, are attached using end plates 14 in the manner described above .
For fixing a first beam end to end to a second beam a similar end plate 14 can be used, or alternatively a simple blank ended end plate 70, shown in Figure 10 of the drawings that follow, can be used as is shown in cross- section in Figure 9 of the drawings that follow. The end plate 70 just needs to provide a wall 72 for bolts to abut against and limbs 74, 76 to secure the end plate 70 to the respective beam.
Use of the system described herein minimises the need for welding. The system can, advantageously, be delivered as a flat-pack.
