Abstract
- 14 The manufacture of formwork for curved step changes in height, or curved hobs, in cast in-situ concrete floor slabs can be time consuming and costly. The present invention provides a moulding system for surface profiling of poured concrete slabs that includes 5 sheet metal horizontal components that have curved edges, and sheet metal sidewall components that are curved to match the curved edges of horizontal component. The sidewall components are welded to them to the horizontal components along their curved edges. These curved moulds can be supported on chairs to position them at a predetermined height, and both the chairs and the curved moulds become an integral part 10 of the concrete floor once it is poured. 33 Figure 1 331 Figure 2
Description
Moulding System for Surface Profiling of Poured Concrete Slabs
FIELD OF THE INVENTION
This invention relates to a moulding system for surface profiling of poured concrete slabs, and in particular, but not exclusively to a moulding system for producing surface profiling that contains curvature in a plan view.
BACKGROUND
A significant part of the construction of multi-story buildings is the assembly of formwork for each of the poured concrete floors. The formwork defines the lower surfaces and the outer edges of the slab floors, and the top surfaces are generally open and the concrete is smoothed off as it sets. Increasingly, however, there is a demand for profiling of the upper surfaces, that is, the provision of step changes in the height of the upper surface, or the provision of raised hobs to provide waterproof bases at the bottom of windows or wall structures.
And as the architectural requirements for buildings increase, there is often a need for curved structures. And this requirement for curved structures in turn produces a need for curved or radiused surface profiling of the upper surfaces of the floor slabs.
The construction of moulds or formwork to facilitate the creation of surface profiling is often complex, and can be very time consuming and expensive in both manpower and materials. For example, the formwork or moulds that are required to form a raised hob, or a rebated edge on a floor slab must be cantilevered from the formwork that has been set up to form the floor slab.
Curved or radiused profiling of a concrete slab is that much more complex. The task of producing three dimensional formwork in free space, above the reinforcing steelwork for the slab is particularly demanding. At the same time the curved or radiused shaping must be dimensionally accurate in plan view, to ensure that the profiling will accurately support the window or wall or other structure that will be installed above the curved profile.

-22019101285 24 Oct 2019
Considerable time is spent shaping and positioning plywood formers, and bending thin panels to produce the curvature, and then fixing the formwork together in a robust enough manner so that it will retain its shape and position when the concrete is poured.
Similarly when a curved raised hob is to be placed on an already cast floor slab, much 5 time and considerable cost in materials can be incurred in laying out the desired shape and location, and in forming a mould for the hob, and in providing structural attachment to the floor slab.
What is needed is a better system of producing curved profiles that will not only save on time and materials, but which will also provide the dimensional accuracy and structural integrity that is required.

FIGURE 4 is a cross sectional view YY (as defined in Figure 3) of the second example of a moulding system, and
FIGURE 5 is a perspective view of an alternative spacer for use in the second 10 example of a moulding system.
First Example
With reference to Figures 1 and 2, a first example of a moulding system for surface profiling of poured concrete slabs in the form of a set down moulding system (11) will now be described. The set down moulding system (11) has been designed for use in the construction of poured concrete floor slabs (13) of single and multi-story buildings. The set down moulding system (11) is used to create step changes in the height of the top surface of the floor slab (13) as shown in figure 2. The set down moulding system (11) becomes embedded within the poured concrete and becomes an integral part of the floor slab (13).
In this first example of a moulding system for surface profiling of poured concrete slabs the set down moulding system (11) has a horizontal component (15) and a sidewall component (17). An important feature of the system is that the horizontal component (15) is profile cut to produce a required shape or curve as specified by the architect.
Both the horizontal component (15) and the sidewall component (17) are made of galvanised sheet steel, and the sidewall component (17) is curved by light bending of the sheet metal material to match the shape of the curved edge (19) of the horizontal component (15). And then the sidewall component (17) is structurally attached to the
207076AUA_Innov_Spec_as_filed_240ct2019.doc/PA
-72019101285 24 Oct 2019 horizontal component (15) along the curved edge (19), by producing a welding joint along the curved edge (19).
As noted above, the shape of the curved edge (19) of the horizontal component (15) is produced by profile cutting, for example by plasma or laser cutting the sheet metal stock material. In this example, an outer or free edge (21) of the horizontal component (15) is similarly profiled or curved, and in this way the horizontal component (15) is essentially an elongate and slender curved section of sheet material where the long edges, (19) and (21), have a similar curved shape or profile and are generally parallel to one another.
The sidewall component (17) is also an elongate component with a top edge (23) that is 10 parallel to a bottom edge (25). The sidewall component (17) can simply be cut as a long strip using a guillotine, with the width of the cut strip determining the height or magnitude of the step change, or set down, produced by the set down moulding system (11).
The horizontal component (15) can be said to be a base member (27) of the set down moulding system (11). In cases where a long section of mould is required, two or more horizontal components (15) could be joined together, end to end, to produce a longer base member. Similarly, multiple lengths of the sidewall components (17) could be joined together, end to end, to match the length of the base member (27).
A number of gusset members (29) used are used to strengthen the attachment between the sidewall component (17) and the base member (27). The gusset members (29) are configured to hold the sidewall component (17) generally at right angles to the base member (27), and in the example shown the gusset members (29) are welded to both the sidewall component (17) and the base member (27). In figure 1 it can be seen that the gussets (29) are similarly cut from sheet metal material, and they are generally slender in shape and they include holes (31) that allow the concrete to flow, so that the gussets provide only a small discontinuity in the structure of the concrete adjacent to the set down.
It can be seen that the set down moulding system (11) further includes a number of supports or chairs (33). The supports (33) are configured to support the assembled
207076AUA_Innov_Spec_as_filed_240ct2019.doc/PA
-82019101285 24 Oct 2019 sidewall component (17) and base member (27) at a predetermined height above a floor of a formwork structure for producing a concrete floor slab.
The supports (33) each include a support base member (35), a column member (37) and a top member (39). The column member (37) has a structural connection to both the base member (35) and to the top member (39). The base member 35) is configured with fastener holes for attachment to the floor of the formwork structure. And the top member (39) is flat and is configured to engage with the mould base member (27) using suitable fasteners or welding, and in this way is able to support the assembled sidewall component (17) and base member (27).
Although not shown, the supports (33) can include a diagonal brace member that is configured to assist the column member (37) in resisting side loads when concrete is poured on one side of the sidewall component (17).
Second Example
With reference to Figures 3 and 4, a second example of a moulding system for surface profiling of poured concrete slabs, this time in the form of a hob moulding system (61), will now be described. The hob moulding system (61) has also been designed for use in the construction of poured concrete floor slabs of single and multi-story buildings. The hob moulding system (61) is used to create raised hobs in the top surface of the floor slab. As with the set down moulding system (11), the hob moulding system (61) also becomes embedded within the poured concrete and becomes an integral part of the floor slab.
The hob moulding system (61) has two horizontal components (63) and two sidewall components (65) that form a box section mould. The bottom of the box section mould is generally aligned with an upper level of the proposed floor slab, and the top of the box section defines an upper surface of a raised hob to be formed integrally with the floor slab.
Alternatively, the hob moulding system (61) can be used to produce a raised hob on an existing floor slab. In such a case the hob moulding system (61) can be structurally fastened to the floor slab, and/or reinforcing connections can be provided between the
207076AUA_Innov_Spec_as_filed_240ct2019.doc/PA
-92019101285 24 Oct 2019 existing concrete slab and the concrete that will be poured into the moulding system (61) to produce the raised hob.
As with the set down moulding system (11) described herein, the hob moulding system (61) is designed to produce non-straight, or curved profile changes in a floor slab. And for this reason, the two horizontal components (63) both have curved or shaped long edges. The sidewall components (65) are curved to match the curved edges of the horizontal components (63).
Both the horizontal components (63) and the sidewall components (65) are made of galvanised sheet steel. One of the horizontal components (63) forms a base member (67) of the hob moulding system (61), the other horizontal component (63) forms an upper member (69) of the hob moulding system (61).
As noted above, the hob moulding system (61) includes two sidewall components (65) and these are arranged in a side by side relationship and they form the sides of the box section and of the raised hob produced using the hob moulding system (61).
The shape of the two horizontal components (63) is produced by profile cutting sheet metal stock to meet the architects shape requirements. The upper member (69) is identical in overall shape to the base member (67). In figure 3 the upper member (69) is shown having a short straight section at each end, and a radiused curve in the centre section. However, it is envisaged that the upper member (69) and the base member (67) could have any shape, for example a “U” shape or a wavy shape.
Each sidewall component (65) is an elongate component in the form of a wide strip of sheet metal having a top edge (71) that is parallel to a bottom edge (73). Each sidewall component (65) is gently curved to match the shape of the curved edges of the upper member (69) and the base member (67). Both the top edge (71) and the bottom edge (73) of each sidewall component (65) are structurally attached by welding to the curved edges of the two horizontal components (63) to form the curved box section form shown in figures 3 and 4. The width of the strip that forms the upper member (69) and the base member (67) determines the height of the raised hob formed by the hob moulding system (61).
207076AUA_Innov_Spec_as_filed_240ct2019.doc/PA
-102019101285 24 Oct 2019
The upper member (69) and the base member (67) each have large openings in the form of rectangular holes (75) cut in them, and in fact more than half of the area defined by each horizontal component (63) is cutaway. The cut-outs do not extend to the edges of the horizontal components (63) however, and bridging sections (77) remain between adjacent rectangular holes (75), the bridging sections (77) spanning between opposite edges.
The rectangular holes (75) allow concrete to be poured into the hob moulding system (61), and they allow the concrete within the hob moulding system (61) to be mix with, and cure with, the concrete of the rest of the floor slab.
In the figures it can be seen that the hob moulding system (61) includes a number of spacer members (79) which span between the sidewall components. The spacer members (79) include a vertical web portion which spans between the sidewall components (65), this vertical web portion containing a hole (80) to allow the concrete on either side of each spacer member (79) to join up to give the raised hob greater uniformity and strength. The spacer members (79) can be secured in place by welding them to the horizontal components (63) and the sidewall components (65).
Figure 5 shows an alternative spacer member design (81) which includes a horizontal base tab (83) that can include at least one fastener hole. Such a design is useful when creating a raised hob on an existing floor slab. The spacer member (81) can be structurally secured to the existing floor slab using suitable masonry fastening systems, and this way the raised hob becomes structurally secured to the existing floor slab when it is later poured and cured.
As an alternative to the use of the spacer members (79 or 81), or in addition, gussets of the type described in the first example could also be used within the hob moulding system (61) to help keep the sidewall components (65) at a specified angle (usually right angles) to the base member (67). As with the spacer members (79 or 81), the gussets could be welded in place.
The hob moulding system (61) can also include a plurality of supports of the type shown and described with reference to the set down moulding system (11) and figures 1 and 2.
207076AUA_Innov_Spec_as_filed_240ct2019.doc/PA
-11 2019101285 24 Oct 2019
The supports perform the same function as the supports (33) of the first example in that they support the hob moulding system (61) at a predetermined height above a floor of a formwork structure for producing a concrete floor slab.
