erecting the said upright members 11 to 23 vertically and in a spaced relationship to each other on the said foundation;
providing securing members 24 and securing adjacent spaced apart upright members together with the securing members 24; and
- in situ casting wall sections 26 [Figure 5]
between thereby | pairs forming | of the | spaced apart upright structure . | members |
The upright | members | 11 | to 23 are pre-cast | upright |
members made of | any | suitable hydraulic | setting |
composition such as a mixture of Portland cement and a suitable aggregate material.
All the corner joints in the structure 10 are formed by the pre-cast upright members and for this purpose the upright members are provided with suitable crosssectional configurations such as substantially L-shaped [member 11], T-shaped [member 13], cross-shaped [member 21] and stepped-shaped [member 18] cross-sectional configurations.
Where two adjacent corners are relatively far apart from each other [for example members 19 and 11] a flat member 20 which is flat from side to side may be erected between them, thereby shortening the length of the wall sections 26 to be cast in situ between the
- 11 BAD ORIGINAL said corners. This does not only strengthen the structure but it is also easier to cast a shorter wall section .
Each upright member includes a fit formation in the form of a groove 29 in the sides thereof which are in use received against the in situ cast wall sections 26 thereby to improve the joint formed between an upright member and an in situ cast wall section 26.
Each upright member 11 to 23 is provided with two receptacle formations in each of the grooves 29, the receptacle formations being in the form of eye formations 25 (as shown in Figures 2 and 3 J.
The securing members 24 in use serve to prevent relative movement between the uprights members.
Referring now to Figure 4a a securing member 24 comprises an elongate body formed by two parallel bars 24.1 and 24.2. The bar 24.2 is shorter than the bar 24.1 and is secured to the bar 24.1 by means of spacers 24.3. Transversely attached to each end of the securing member 24 is a wedge-shaped attachment formation 24.4. The narrow end of each wedge-shaped attachment formation 24.4 extends away from the body of the securing member 24.

- 13 BAD ORIGINAL sections 26 in situ between adjacent upright members.
The shuttering comprises panels 27 and securing members
28. The shuttering fits onto the sides of the upright members.
The securing members 24 also act as reinforcing in the in situ cast wall sections 26.
The in situ cast wall sections 26 may also include one
or more | door | frames [not | shown] | and/or | windows | [ not |
shown] | cast | therein . | Furthermore, | plumbing | and | |
electrical wiring [not shown] may | also be cast in | the | ||||
in situ | cast | wall sections | 26. |
Referring now to Figure 6, one or more gables are formed on the structure. The gables are formed on opposing ends of the structure 10. The gables are formed by casting a gable centre piece 30 in an in situ cast wall section. A gable wall 38 [Figure 8] is then cast by means of shuttering 27 and 28 [as shown in Figure 6]. The gable wall 38 slants downwardly from the gable centre piece 30 to the wall structure 10.
The gable centre piece 30 comprises a cast post with an aperture 30.1 therethrough. The base 30.2 is narrower than the rest of the post 31 and is in use received in an in situ cast wall section 26. The top 30.3 of the centre piece 30 is angled.
BAD ORIGINAL ft
Referring now to Figure 7 grooves 31 are formed in the in situ cast wall sections 26 in use to receive roof rafters 32 therein. The bottoms 31.1 of the grooves 31 are slanted downwardly from the inside surface of the wall section 20 to the outside of the wall section.
The grooves 31 may be formed by casting blocks such as wood blocks [not shown] in the in situ cast wall section and removing the blocks once the wall section has set.
Tie means in the form of wire 33 are also cast into the in situ cast wall sections 26.
The structure 10 may also be provided with a roof 33.
The roof 33 includes a roof beam 34 extending from one gable centre piece to another and extends through the apertures 30.1 in the centre pieces 30. Roof rafters 32 are provided in pairs and are secured to each other at their one or upper ends with a single bolt or the like [not shown] allowing a pair of rafters 32 to hinge transversely over the roof beam 34 with a roof rafter extending downwardly from each side of the beam 34.
The other or lower ends of the roof rafters 32 are received in the grooves 31 and are tied to the in situ cast wall sections by means of wire 33.
Insulating material such as aluminium foil 35 may then
