Support system and structure supported thereby

1. A weighted support assembly for supporting an upright post, said support assembly comprising:

a base frame comprising:

an elongate base member attached to the post and extending outwards from the post; and

a plurality of upright elongate members ascending from the base member;

a plurality of weights stacked in layers upon the base member; and

a top frame comprising:

an elongate top member attached to the post and extending outwards from the post above the base member; and

a plurality of elongate members descending from the top member;

wherein:

said ascending members engage telescopically with corresponding said descending members, and

each said weight defines a hole therethrough which is penetrated by at least one of said ascending or descending members.

2. A support assembly according to claim 1 wherein the top member lies against the upper layer of said layers of weights.

3. A support assembly according to claim 1 or 2 wherein said weights are stacked with the top of an underlying said weight nesting into the base of a respective weight immediately above.

4. A support assembly according to claim 1 wherein the extent of said telescopic engagement is such that a layer of weights may be added or removed from said stack to create a new upper layer of weights while still providing said telescopic engagement and for the top member to bear upon said new upper layer of weights.

5. A support assembly according to claim 1 wherein one end of said top frame comprises a hollow section end portion adapted to slide along said post.

6. A support assembly according to claim 5 wherein the elongate top member is releasably fastened rigidly to the post.

7. A support assembly according to claim 1 wherein the elongate base member is fastened rigidly to the post.

8. A support assembly according to claim 1 wherein said post comprises a square or rectangular hollow section steel member and one end of said base frame has a corresponding square or rectangular hollow section end portion which can slide along said post.

9. A support assembly according to claim 8 wherein the end portion is fastened to the post.

10. A temporary hoarding, sign or fence structure comprising a plurality of upright posts connected by a plurality of generally horizontal rails where attached to each post is a weighted support assembly according to claim 9 .

11. A method of erecting a temporary structure which includes the steps of:

positioning a plurality of weighted support assemblies each according to claim 9 ,

securing a post to each respective said base frame and top frame, and fastening structural components to said posts.
