Complete Specification for the Invention entitled :CO IUCRETE WITH HOLLOW SECTION

STRUCTURING.

The following statement is a full description of this invention, Including tho best method of performing It known to me:-* *Note: The description is to be typed in double specing, pica type face, In en erea not exceeding 250 mm In depth end 160 mm In width, on tough white paper of good quality and It is to be Inserted Inside this form.

11710/76-L F. D. Atkinson. Government Printer, Canberra THIS INVENTION is associated with the use of hollow section steel by the off-site or on-site manufacture of panels or modules of this hollow section which serves, when positioned for concrete constructions, to support the steel reinforcing for the concrete to be poured and also act to rigidly or semi-rigidly hold the construction erect till concrete is poured and set. Moulding boards can be attached directly to the outside of these panels or modules so the pouring of concrete can be achieved without the need 10 of external moulding frames being constructed.

0* S0 The basic components of these hollow section panels or modules are the two opposite sides of the hollow section frame which forms the outside of the panel or module. To this, 0S 0 06 '00 the moulding boards can be attached to contain the concrete •go• during pouring. The two opposite hollow section frames are separated by spacing rods to give the panels or modules and S the concrete construction the specified thickness. Reinforcement is attached or welded to the spacing rods within the panels or modules. Positioning of panels or modules then occurs with the moulding boards being attached to the outside of the panels or modules to contain concrete being poured.

00 *The final result after pouring the concrete and the 6 o concrete having set is that the hollow section steel remains set in the concrete and exposed on the surface of the concrete. Exposure of hollow section steel at the surface after concrete has set and moulding boards have been removed means that attachments of various things can be made to the concrete construction containing the hollow section by direct attachment to the hollow section. Hollow section is narrow -1enough to allow coverage by plaster cement if nothing is to going to be attached to the externally exposed hollow section surface.

The modules can be of hollow section or ptnels of more than one square module. An example of a typical module is 750mm. by 750mm. with the hollow section being 20mm.x 1.6mm. thickness steel, spacing rods are 110mm. long and 12mm.

in diameter giving concrete construction or wall a thickness of 150mm.. A steel reinforcement layer or layers is or are 10 set between each frame or side of hollow section and attached or welded to the spacing rods for positioning. Each module or panel can be welded or attached to the next module or panel.

A particular embodiment of the invention will now be described with reference to the accompanying drawings in which: Figure 1 is a isometric vie/ of a panel of two modules with a third module to be attached or welded as part of a concrete construction or wall. The panel 1 of two modules is seen to adjoin the module 2. Ilhe hollow section frames 3 on each side are separated and set at the required thicKness or spacing tor the concrete conscruction or walL oy spacing rods 4. Modules which form the bottom level of modules have three sides excfpt for the first module which has four sides while modules at higher Levels have two sides.

A steel reinforcement layer 5 is set between the hollow section frames 3 and attached to the spacing rods 4 for positioning between the two opposite frames of hollow section.

The attachment of the third module 2 to the panel 1 of two -2modules can be made at attachment sites depicted by 6. All hollow section is sealed basically by welding in the manufacture of modules before moulding boards or covers are attached and concrete is poured at construction stage. Attachment sites 6 can be welds or screwed or bolted by tags that are welded or attached to the hollow section at these attachment sites 6.

Moulding boards or covers are attached to outside of the hollow section frame on each side of each module or panel by screws or bolts set in previously tapped holes 7. Tapped 10 holes 7 for attachment of external moulding boards or external moulding covers can be sealed by cement plaster after concrete as set ana external moulding boards or covers are removed.

Claims (9)

1. A module or panel of modules for reinforced concrete construction,comprissing: Steel hollow section frames, Spacing rods, Steel reinforcement, Moulding boards, such that opposite sides are formed from steel hollow section frames and are separated by spacing rods which set the thick- ness of the module or panel of modules with steel reinforcement being supported within the opposite sides of the hollow section frames and moulding boards being attached to the outside of the hollow section frames of the module or panel of modules with hollow section steel frames of these modules or panels hold- ing moulding boards in position and erect.

2. The modules or panel of modules as claimed in claim 1, wherein a construction of adjoining panels or panel of modules is formed by being joined together by welding or by a fastener through a metal tag or suitably joined together.

3. The modules or panel of modules as claimed in claim I or 2, characterised by the hollow section steel with layers or a single layer of steel reinforcement being set and positioned between the two opposite frames of hollow section by being attached or welded to the spacing rods of the modules which subsequently support tne steel reinforcement inside each module or panel or the construction of panels and modules or panels or modules.

4. The modules or panels of modules as claimed in claim 3 suc~ that the layers or single layer of steel reinforcement are characterised by being supported by steel hollow section frames -4- opposite to each other in each module or panel of modules by welding or attachment.

The modules or panel of modules as claimed in claims 1 or 2, wherein the steel hollow section frames, are characterised by holding externally attached moulding boards or covers or form- work erect and in paoition during pouring of concrete and when concrete has set moulding covers are removed leaving the opposite hollow section frames set in the required concrete construction or pattern of adjoining modules or panels.

6. The modules or panels of modules as claimed in claim characterised by the opposite hollow section frames set in a completed required concrete construction having faces exposed and attachments being made to opposite exposed faces of hollow section of the concrete construction.

7. A method of construction of modules or panels of modules as defined in claim 1, characterised by welding hollow section steel frames to spacing rods and also welding reinforcement to spacing rods.

8. The construction of modules or panels as claimed in any one of claims I to 7 wherein they can be set in required position on construction site for concrete to be poured or set in position away from construction site and placed into required position as completed module or panel or construction of panels or modules.

9. A module or panel substaintially as herein described with reference to accompanying drawings. Dated this 15th. of May,1993. George Anthony Contoleon. APPLICANT.
