Definitions
- the invention relates to a shutter block, such as a polystyrene shutter block, used in a method of concrete construction.
- the reinforcing rods required for many concrete constructions are difficult to situate and keep in place using the existing shutter blocks. This is particularly so when an exact fit between separate shutter blocks is not possible.
- An object of the present invention is to provide a simple and quick means of joining one shutter block to another while enabling reinforcing rods to be quickly and firmly fixed in place. This will enable a quick and efficient method of concrete construction.
- this invention provides for a shutter block, the shutter block including two regularly spaced shutter walls, each shutter wall has a continuous ridge on its top and a continuous recess in its bottom, webs are used to connect the shutter walls and the webs are adapted to hold reinforcing rods relative to either the top and/or the bottom of the web. It is to be appreciated the reverse orientation of the continuous recess and continuous groove is intended to be covered by the invention.
- one or more dividers can be used to close the, or any, open ends of the shutter blocks or can be used to create sections within the shutter block.
- the placement of one or more individual shutter blocks together will form larger shutter walls, joined by one or more webs adapted to hold reinforcing rods relative to the top and bottom of a web.
- the internal faces of the shutter walls will include shaped grooves in which complementary parts of the divider can fit to close an open end of the shutter or be used to create a section within the shutter block.
- the shaped grooves can be dove ⁇ tailed or approximately dove-tailed with curved edges.
- One of the external faces of the shutter walls can include dovetailed or the like shaped grooves which assist an external plaster coating to key to the wall.
- the shutter walls are corrugated on their outer and end faces.
- a further aspect of the invention provides for a means of manufacturing the shutter blocks in which a web or webs is or are placed between two moulds of a shutter wall which have been filled with polystyrene balls or a similar material.
- the polystyrene balls in the mould are heated and expand to form two shutter walls joined by the at least one web.
- a mould filled with polystyrene balls can be heated to form a divider.
- a further aspect of the invention provides for a means of manufacturing the shutter blocks in which a mould of the divider is filled with polystyrene balls or similar material.
- the polystyrene balls in the mould are heated and expand to form a divider.
- the shutter walls and dividers can be ejected from the moulds by a blast of compressed air.
- Figure 1 shows a side elevational view of a shutter wall (being part of an example of the invention) ;
- Figure 2 shows a plan view of a pair of shutter walls linked by webs to form an example of shutter block according to the invention

- Figure 14 shows an elevational view in the direction of arrows Y-Y (Figure 12) of the corner block shown in Figures 12 and 13;
- Figure 15 shows an isometric view of the corner block shown in Figures 12 and 13;
- Figure 16 shows a plan view of a high floor unit for use with the shutter block and end wall blocks shown in Figures 2 and 5;
- Figure 17 shown an elevational view of the high floor unit shown in Figure 16;
- Figure 18 shows an end elevational view of the high floor unit shown in Figures 16 and 17;
- FIG 19 shows an isometric view of the high floor unit shown in Figures 16 to 18.
- the shutter block consists of two regularly spaced shutter walls 1, 2 of equal similar dimensions.
- each of the shutter walls 1, 2 includes a plurality of similarly dimensioned and dove-tail shaped anchoring grooves 4.
- the dove-tailed grooves 4 are grouped in sets of four 5 and the sets are spaced regularly along the shutter walls.
- the shutter walls 1, 2 are joined by webs 3 (shown in detail in Figures 9 to 11) positioned at intervals 6 along the shutter walls between the sets of grooves 5.
- the space between each set 5 of grooves 4 is at least twice space 8 between each individual dove-tailed groove 4 of a set 5.
- Each shutter wall 1, 2 has on its top or bottom face a continuous ridge 9 or continuous recess 10 ( Figure 3). Where the shutter wall 1, 2 has the continuous recess 10 on its top the bottom will have the continuous ridge 9.
- the continuous ridge 9 is of such a proportion that it fits in the continuous recess 10 of a similar shutter wall above or below.
- each shutter wall 1, 2 are preferably corrugated.
- the shutter walls 1, 2 can be connected by at least one of the webs 3.
- the webs 3 join the two shutter walls 1, 2 and have a width of smaller dimensions than the overall width of the pair of shutter wall 1,2 as shown in Figures 2, 3 and 4.
- the webs 3 can be stamped from or moulded from a sheet of material which is preferably metal.
- the configuration of an example of the web is shown in Figures 9 to 11.
- Figure 9 is shown a web 3 before it is folded into the shape shown in Figures 10 and 11.
- the shape and dimension of a web is symmetrical about the horizontal axis A-A and the vertical axis B-B.
- the web 3 is bent along the horizontal bend lines C-C and D-D and (alternatively not shown) can be bent along vertical bend lines.
- the web 3 is also bent along lines E-E and F-F to form flanges 15 and 18 at either side of the web 3.
- the web 3 includes four similar sites 16 for the fixing of reinforcing rods.
- the sites 16 include lugs 17 which can be twisted to an open position so that a reinforcing rod of smaller diameter than the recess formed between the sites 16 and lugs 17 can easily be placed in the recess.
- the lug 17 can then be twisted back to the closed position, as shown in Figures 9 and 11, so the reinforcing rod is fixed in place. It should be appreciated that there may be variations in the number and placement of the sites so long as there is at least one site on the top and bottom of the web 3.
- the web 3 is further configured to include two larger recesses 19 and 20 for fixing one or more reinforcing rods (not shown) to enable a bond beam to be formed when the space between the shutter walls is filled with concrete. Any reinforcing held in larger recesses 19, 20 is held in position by wire ties (not shown) .
- the top or bottom face 21, 22 of a divider 13 or end wall has a single anchoring ridge 14 or a single anchoring recess 15.
- a divider 13 has the single anchoring ridge 14 on its bottom face it has on its top face the single anchoring recess 15.
- the single anchoring ridge 14 is of such a proportion that it fits in the single anchoring recess.
- the side faces 23 of the divider 13 are dove-tailed so that they are an insertable fit into the dove-tailed grooves 4 of a shutter wall.
- the divider 13 can be inserted so that the single anchoring ridge 14 on the top of the divider 13 corresponds to the continuous ridge 15 on the top of the shutter wall.
- Another option is for the single anchoring recess 15 on the top of a divider 13 to correspond to the continuous recess on the top of a shutter wall.
- a shutter block is formed by positioning at least one web in a mould, before two shutter walls are formed by heating polystyrene balls placed in the mould.
- a divider is formed by heating a mould filled with polystyrene beads for an end wall.
- FIGs 12 to 15 is shown an example of corner shutter block 24.
- This construction of block has similar webs 3 to the webs shown in Figures 9 to 11.
- the overall length of the walls 25, 26 are modular lengths of a standard block shown in Figure 4. This enables a standard block wall configuration to be built with the blocks.
- the internal walls 27 of the block 24 have dovetailed grooves 4 in a similar format to that of the standard block.
- the upper edge 8 has a ridge 29 while the lower edge 30 has a complementary recess 31.
- FIG. 16 to 19 is shown a high floor unit 32.
- the unit 32 is used on the periphery of a floor slab, for example where a door or window is to be situated.
- the edge 33 of the unit 32 is aligned with an outside wall of the floor slab. Concrete can then be screeded off level with the top surface 34 of the unit 32.
- the inner face 35 of the unit 32 is supported by spacers 36 which in this example are also constructed from the polystyrene material.
- the spacers 36 are I-shaped ( Figures 18 and 19) to enable reinforcing to be fitted along the edge of the floor slab.
- a plurality of the shutter blocks are positioned in place leaving spaces for windows and doors. These spaces may be relatively easily formed to plan dimensions by cutting the polystyrene material as required. Dividers are positioned where necessary to close off any open ends of the blocks.
- the erected block walls can be stabilised by reusable bracing formed from galvanised iron metal sections which are mounted alongside an inner face of the erected walls with angled sections tied or braced down to the floor slab and fixed by dyna bolts or the like to the floor pad.
- the exterior wall of the blocks being tied by wire ties to the inside bracing to form a rigid framework for a concrete pour in the blocks.
- the shutter blocks form a structure which can with framework and bracing be used to create two storey structure as well as a single storey structure.
- shutter block for a range of constructions or structures which include concrete walls, these include residential, commercial and industrial buildings.
