ABSTRACT OF THE DISCLOSURE
A base plate for supporting and positioning a vertical wall panel of a building structure, a plurality of such plates when in connected position in a plane to form a ring. The base plate receives and supports thereon the base of a wall panel.
To the upper surface of the plate are secured upwardly projecting, outwardly extending hooks to receive and properly position the base of the wall panel so that adjacent wall panels similarly received and positioned on adjacent similar base plates in connected position will be contiguous to that wall panel and to retain the wall panel therein against relative vertical or sideways movement. Connectors are provided at the ends of the plate to releasably secure the plate to cooperating ends of adjacent, similar base plates.
The base plates according to the present invention greatly facilitate the construction of circular building structures, reducing manpower requirements and the technical skills of manpower used in erecting such strucutres.

Description
BACK~OUND OF THE INV~TXON
The present invention relates to a ba~e pla~e for supporting and positioning a vertical wall panel of a buildin~
structure, and more par~icularly relates to the construction of base pla~es to be used in conjunction with wall panels in constructing, for example, demountable building structures.
The base plate according to the present invention has been develo~ed for use in conju~ction with, for example, the demountable porta~le re6ervoir structures described and illustrated in my copending Canadian Patent Application Serial No. 441,127~ ~iled November 14, 19B3. Such portable resevoir structures may be erected and dismantled as required in remote or frontier areas, and are readily trans~ortable to and erectable in remote areas usin~ a minimum of manpower and technical skill.
Demountable storage containers such as reservoirs, for which the base plate of the present invention is particularly, but not necessarily exclusively~ suited, ha~e previously u6ed simple rail or angle iron supports for ~he bases of the walls o~ these structures (e.g. see Green U.S. Patent No. 3,460,705 issued Augu6t 12, 1969 and Levens W.S. Patent No. 3,~19,079 issued June 25, 1974). More permanent types of supports have been described and illustrated, for example in Rossit~o et al.
U.S. Patent No. 3,gl7,104 issued November 4, 1975 and ~Iolschlag U.S. Patent No. 4,240,562 issued DecembeL 23, 1989.

Turning to FIGURE 1 there is shown a base plate 2 having an elongated, rec~angular body 3. The body has an upper planar surface 4 to receive and support thereon the base of the wall panel 14, and a lower planar surface 6, parallel to upper surface ~, ~his lower surface 6 to be supported on a fla~

Upwardly extending from upper surface 6 are a pair of spaced hook bracke~s B. While shown as being made from fla~

As well, relative movemen~ sideways of wall panel 14 with respec~ ~o base plate 2 and relative ve~tical movement of the wall panel with respect ~o the base plate will be restric~ed by hools brackets 8, ~ t the ends of recta~gular pla~e body 3 are provided connector plates 16, one end o~ connector pla~e 16 being bolted by a pair of bolts 1~ to base pla~e 2. and the other end of connector plate 16 being bol~ed by a single bol~ 2G to an adjacent, similar base plate 2 (FI~U~ES 1 and Z). In practice, connector plates 16 are bolted by bolts 1~ to corresponding ends of bas~ plates 2, preferably prior to delivery to the construction site. This facilitates tha joining of base plates
2 since then only the other end of connec~or plate 16 must be bolted by bol~ 20, ~o an adjacent base plate 2. Connector plate 16 i6 preferably of elonga~ed shape as shown, to bridge a gap between adjacen~ base plates 2 formed when the base plates a~e laid out in circular outline. A hole 22 is provided in the middle of that connector plate, ov~r this gap, to receive an anchor pin or bolt.
In actual pract;ce, a site of appropriate sur~ace area to receive the s~ructure is first clearad and levelled. In some a~plications or where soil conditions dictate, tha base plates and suppor~ing walls may be erec~ed on a prepared concrete base curb. In other cases, they may be located on compacted earth. Where a circular structure i~ to be erected, the wall base plates 2 are laid down in circular fashion ; measuring out from the proposed center of that s~ructure a ~ imilar distance, (FIGURE 3). The plates are joined by connector plates 16. The intended size of the structure dictate~ ~he number of base plates 2 ~o be used. The platas can be shif~ed on the surface until a comple~ed regular circle is achieved. Anchor rods as required are then in6talled through ancho~ holes 22 in connector plates lS.
Wall panels 14 are brought to the site and laid out like spokes of a wheel (FI~URE 3). ~rom this position two men can elevate each panel, engaging pins lO on bar 12 a~ ~he base of the wall panels 1~ into the receptacles of hook bracket~ 9 on base plates 2. The first wal]. panel 14 can be held in place by two workmen or tied in position, for example, by ropes. The second panel can then be erected an~ appropriately connected to the first panel, c~re being taken -that ~he edges of the pane~s are con~iguous.
It will be unders~ood that, using the base plate and wall panel construction according to the present invention, a structure having wall~ of regular circular con~truction may be readily erected by a small number of labourers, using few tools, and requiring lit~le in the way o~ technical skills.
The base plate construction according to the present inven~ion lends itself readily to con~ainerization and quick erection and dismantling of the wall panels of the structure.
It will be further understood that, while the invention has been described in associate with circular wall structuLes, the base plate may be readily adap~ed ~o the erection of structures having 1a~ sided outlines, such a~
rectangulaI wall structures.
Thus it is apparent that ~here has been p.rovided in accordance with ~he invention a base pla~e for demountable vertical wall panels that fully satisfies the ob jectsO aims and advantages set forth above. While the invention ha8 been described in conjunc~ion with specific embodiments ~hereof, it is evident that many alternatives. modifications and variations will be apparent ~o tho~e skilled in ~he art in light of -the foregoing descriptionn. Accordingly, it is intended to embrace all such al~ernative~, modi~ications and variations as ~all within ~he spirit and broad scope of the appended claims.
