Definitions
- the present invention relates to a method and apparatus for construction using pourable concrete material.
- the present invention relates to interchangeable and reusable lightweight formwork and scaffolding, and to a method and apparatus to set the re-useable lightweight formwork and scaffolding in position for the in-situ construction of vertical, horizontal and other shaped concrete structures.
- the present invention includes a method to transfer the trapped hydraulic forces of in-situ cast concrete to assist alignment and positioning of the formwork in its true positions.
- the present invention also seeks to utilise the same lightweight formwork to enable reinforcing steel to be used to post-tension both vertical and horizontal and other shaped in-situ concrete structures.
- Constructing buildings, suspended slabs, walls, columns, beams or the like of in- situ concrete material has inherent advantages over other construction methods and materials, such as pre-cast concrete, timber, brick and manufactured wall cladding, etc., including considerably higher strength, durability and integrity.
- Post tensioning in-situ reinforced concrete is used almost universally on large scale constructions, demonstrating its effectiveness as a requirement with concrete building materials.
- in-situ concrete construction methods are extensively used for major construction work, it is rarely used for small scale constructions, particularly in country regions.
- a large portion of the cost of in-situ concrete construction is due to formwork costs, wastage of formwork materials, and, costs of materials handling and scaffolding for multistorey exterior work.
- Traditional techniques of vertical and horizontal in-situ concrete construction which use formwork panels and support material are required to be cut to shape on site or assembled with heavy lifting equipment and manually secured in their positions by skilled trades people.
- most formwork components are not interchangeable. It is also a costly procedure to post-tension the concrete structure and the waste of non-reusable materials after the concrete pour is often considerable.
- a major problem with in-situ concrete walls and slabs is the formation of shrinkage cracks which occur in slabs and walls.
- a further problem when casting in-situ concrete walls is positioning the wall formwork and maintaining it in its true position both during assembly and during the concrete pour.
- Another major problem of cast in-situ building is the large variety of trade skills and quantities of formwork and scaffolding equipment required when producing vertically cast in-situ slabs, concrete walls, and columns, etc., and the large quantities of different formwork and scaffolding equipment and coordination of trade skills required to produce the formwork for multi-story suspended in-situ concrete slabs, beams and walls, etc., in single or multi-story constructions.
- the present invention seeks to address the afore-mentioned disadvantages of the prior art.
- the present invention seeks to utilise the same lightweight formwork with it's interchangeable and completely reusable components to produce any one or combination of vertical, horizontal, and other shapes of in-situ concrete structures that may be connected together to provide a lighter and complete post-tensioned and insulated reinforced concrete structure with integrity and greater strength, reduced building materials that are difficult to compromise and formwork equipment wastage and construction workers reduced to one trade skill for the complete concrete structure.
- the special purpose reusable and interchangeable lightweight formwork and special purpose scaffolding enables the production of a complete in-situ concrete structure produced by trained semi-skilled trades persons with wall insulation sheeting in position and other components insert moulded in selected positions in the structure to satisfy a variety of safety and mandatory requirements and reduce the costs of following electrical, plumbing and specialist fit-out trade skills.
- the system opens up structural design possibilities for both architects and engineers to design new building structures utilising both strengths of the vertical in-situ walls and suspended concrete slabs locked together post-tensioned to provide complete and improved structural integrity at reduced maintenance costs for the entire life of the building.
- the formwork system/scaffolding and components are lightweight to enable manual use. They are interchangeable and used for both vertical and horizontal in-situ concrete constructions, all components are reusable thus reducing materials handling and on site material requirements and costs for in-situ vertically cast concrete walls, columns and horizontal suspended concrete slabs and beams.
- the present invention seeks to provide a complete method of construction and an apparatus or kit therefor, which has advantages or at least provides an alternative to the traditional and prior art methods of construction, using pourable concrete material to produce a complete cost effective building with certified concrete and certified structural steel placement for the complete building structure.
- the present invention seeks to utilise the same light formwork to produce both vertical and horizontal in-situ concrete building structures which provide greater strength and reduced materials and reduced building costs.
- In-situ concrete structures enable engineers to introduce the most stringent building codes for safety at no extract costs.
- the invention introduces in-situ concrete as an alternative cost effective construction option, it opens up design possibilities for vertical and horizontal in-situ concrete structures. Both the slabs and walls are produced by the same trade skills and a formwork in a kit form with interchangeable components that enables different shapes and designs to be easily achieved.

- the guide members 2 may be affixed to the concrete slab 3 by using concrete bolts, which may be later removed.
- FIG. 3(a) and 3(b) show side and front views of a basic formwork panel 13, whilst Fig. 3(c) shows a formwork panel 13 having additional formply supports, by inserting a support insert 14.
- a guide member 2 which is similar in size to the formwork straight edge supports, is initially positioned and secured on top of a foundation means, such as a concrete slab flooring 3. This guide member 2 is carefully marked out and positioned to ensure that one side of the formwork thereabouts is correctly positioned. Once the guide member 2 is positioned and secured to the foundation 3, a formwork panel apparatus is positioned thereto. Both base guide members may be fixed to the substrate surface to adjust the wall thickness and positions. As seen in Fig. 1, the formwork panel apparatus includes a pair of opposing formply members 4 and 5 which are progressively attached to the formwork panel members and maintained in a spaced apart relationship by spacers 6.
- one opposing panel member is not fixed to the substrate surface 3, but rather, it remains floating.
- pourable settable concrete material may be supplied through a top opening 20, in a continuous pour between the opposing formply members 4 and 5, and allowed to set.
- the rising forces of the vertically cast liquid concrete are trapped between the opposing panel members 4 and 5.
- the forces are equally transferred from the opposing panels to the straight edge and strong back supports.
- the strong back supports transfer the forces to the extent of the top and bottom locking pins that space the opposing strong backs at a set distance apart.
- the trapped forces of the liquid concrete are evenly applied to the opposing panel members, the opposing lightweight panel members self-align to the fixed guide member to the extent of the top and bottom locking pins.

- formwork panels and formply of a variety of shapes and sizes may be used.
- plain panels may be used to form a plain wall surface
- shaped panels to produce different shapes and having blanking means therein may be used to construct windows, doors or other openings in a wall surface
- corner panels may be used to provide either inward or outward corners or T- wall junction on a building, to allow for various walls to join one another
- cross-panels may be provided to allow for multiple walls to join together, etc., to enable a complete building wall structure to be poured and permanently locked together in one continuous concrete pour.
- Post-tensioning and reinforcing steel and insulation may likewise be provided within the foraiwork panel apparatus of the present invention prior to pouring the settable concrete material.
- the post-tensioning rods, reinforcing and insulation material and other components may be supplied and a detailed certified steel inspection carried out at any convenient time during the method of construction, preferably before, or during, positioning of the formply and formwork panel apparatus.
- Appropriate spacers, and sleeves preferably formed of plastics or like material which is not prone to temperature transfer or rust, may be supplied to support and isolate the reinforcing and insulation material within the formwork panel apparatus.
- the vertical cast concrete walls may also be formed to a selected width to provide a cavity for water storage.
- a top support locking pin and wall spacer arrangement 10 (Fig. 3) is fixed in position and adjusted to space and hold the top of the opposing formwork panels in position during assembly and disassembly.
- a variety of support means may then be provided including straight edges (Fig. 1) which are similar in size to the base fixed guide member 2 (Fig. 1).
- the straight edge supports 16 are placed horizontally at predetermined spaces to support the formwork panels and ply sheeting of Fig. 1.
- a locking pin arrangement 9 and 9a may, for example, be produced by providing a suitable conduit material 11 supported by and extending it through the formwork panels 4 and 5 to space the predetermined distance between the opposing strong backs 15, as showing Fig. 1.
- a threaded rod with certified strength may be supplied through the conduit 11 and bolt 12 may be threaded on one or each end thereof to secure the locking pin into position.
- the fixed guide member 2 will be firmly clamped between the formwork panel apparatus 4 and the strong back 15.
- the opposing lightweight formwork panel apparatus is locked into position by the equal forces of the liquid concrete being applied to each formwork panel apparatus 3 and the locking pins 9 and 9a.
- the fixed guide member 2 selects the position of the wall as the concrete forces are applied to the opposing lightweight panels in a continuous concrete pour.
- the straight edges 16 are clamped firmly between the strong backs 15 and the formwork panel and formply apparatus 4 and 5.
- the equal forces of the concrete then forces the ply sheeting against the selected profile of the external supports 4, 5, 16 and 15 and the wall positions selected by the fixed base members.
- the strength of the lightweight formwork to contain the forces of the liquid concrete relies upon the certified strength of the locking pins and strong backs.
- the forces of the liquid concrete applied to the opposing lightweight formwork panels apparatus 3 in one continuous concrete pour aligns the formply and opposing lightweight formwork panels to the full extent the locking pin will allow and self aligns to the selected position of the fixed base member and fixed corner panel which was first secured to identify the true position of the concrete wall.
- the vertical correctness if necessary can be adjusted by the adjustable wind braces during the concrete pour.
- the locking pin bolts may be removed, the locking pin may be extracted from the conduit, and the conduit may be removed or the ends clipped such that they do not protrude and the block-outs removed to enable early stressing of the post-tensioning rods, Fig. 6.
- the top locking assembly may also be supplied above the proposed concrete wall at the top extremity of the formply sheeting, such as shown in Fig. 1 and illustrated by the numeral 9a.
- FIG. 3 Also shown in Fig. 3 are various support panels which may be used to support the form ply joints that are supported by the form panel 5 by placing them in an abutting manner on the opposed side of the formply to that in which the concrete is supplied.
- the support panel 13 and 14 may optionally be included for additional support. Details of the insert panels attached to the support panel are shown in Fig. 3(c), whilst details of the form ply sheeting and sheet ply joints to reduce a joint step are illustrated separately in Fig. 3(d).
- a horizontal slab or beam may also be cast in-situ, this also being within the ambit of the present invention.
- Fig. 4 illustrates the various components and how a horizontal slab or beam may be cast in accordance with the present invention. Whilst Figs. 4(b) to 4(f) illustrate some of the core components used in the construction of the horizontally cast slab or beam, Fig. 4(a) illustrates how they are assembled together, and, Fig. 4(g) illustrates how they are disassembled.
- each base support 50 and 'U' head 51 may be adjusted to the desired height, as required.
- the support base may be of any desired position, depending whether a beam or a slab is to be formed, and may be constructed using the formwork panel components used in constructing the vertical walls.
- the standard procedure in-situ casting of a suspended concrete slab is as follows: 1. select the suspended slab and beam positions; 2. support the under slab beams base on a typical wall or column blanking end placed horizontally at right angles on the typical RHS straight edge adjusted the straight edge and frame to the correct height with adjustable U head supports; Note: the horizontal formwork may also be formed with a wall frame and two standard external wall corner brackets placed horizontally each side of the formwork panel to support the beam base and side frames and formply. 3. assemble the beam reinforcing steel in position on the support base;
- the presently invention provides significant advantages over the construction techniques previously known.
- the components of the present invention lend themselves to being produced in kit form, and sold or licensed for use and re-use on alternative building sites. This consequently reduces skilled labour costs and material costs and wastage.
- various components may be fabricated from a variety of materials, including, but not limited to, any one or combination of steel, rods, tubes sheet metal, or rigid plastics or timber.
- the building constructed in accordance with the present invention has various advantages over timber, plaster, bricks and other materials and former known concrete constructions methods.
- Fig. 5 illustrates the assembly of a special purpose scaffolding apparatus, incorporated with the present invention.
- the scaffolding is attached to the strong back support 31 of a concrete wall 30, and including an outwardly extending platform support 33 and hand rail support 32.
- Platform support braces 34 and 36 assist in supporting the platform 33, which may be attached via one of a plurality of connection points 40 via assembly pin 30.
- a locking pin 37 and locking pin nut and washer 38 are used.
- Work platform and kickboards 41 provide a working surface.
- the assembly procedure is as follows:
- the formwork frames and scaffolding and components are manufactured from commercially available steel tubes and angles.
- the locking pins are commercially available with certified strength to ensure the trapped liquid concrete does not escape.
- the manufacturing processes has been simplified by purchasing the readily available materials, the strong back and straight edge RHS tube can be cut to selected lengths.
- the lightweight frame tubes are welded together for ease of materials handling and transport, and purchasing a quantity of form ply sheeting to form the profile and shape of the concrete surfaces.
- the certified locking pins are readily available along with other small items used during assembly.
- the horizontal forces of the liquid concrete are locked in a formwork sandwich between the opposing formwork apparatus.
- the formwork apparatus consists of loose form ply sheets cut to required size and shape to contain the liquid concrete.
- the form ply sheeting is supported by the frames and horizontal RHS straight edge.
- the horizontal RHS straight edge the panel frames and formply is sandwiched between liquid concrete and the vertical RHS strong backs.
- This simple sandwich of the opposing lightweight formwork apparatus are locked together at a predetermined distance apart by steel locking pins and nuts of specified strength to contain the forces of the vertical cast in-situ concrete.
- FIG. 2 illustrates the wall position lines 17 marked on the floor.
- the base guide member 2 fixed to the floor slab 3 reinforcing steel 7 fixed in position in the wall cavity.
- the special plastic wall spacers 6 attached to the reinforcing steel to hold both the wall insulation and reinforcing steel in position and the opposing formwork panels apart prior to and during the concrete pour.
- FIG. 6 illustrates the post-tensioning rods, end sleeves and nuts for stressing the steel rods after the liquid concrete has begun to set.
