One or more dividers (13) 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.
Description
WO 9S/12720 21 7 ~ 9 3 0 PCTJNZg4/00128 A SHUTTER BLOCK USED IN A METEIOD OF C()~ UN~LAu~ ON
The invention relates to a shutter block, such as a polystyrene shutter block, used in a method of concrete construction.
The existing shutter blocks such as those r~ rrihed in European Patent Nos. û13710S and 0092693 can be difficult to use. This is due to the complex means of ~oining one block to another and often the lack of a suitable means for supporting reinforcing rods within the shutter block .
These existing shutter blocks rely on a complex ~rr;-n,3 L of spigots and recesses which require an exact fit. The spigots are easily damaged. The recesses are easily filled with foreign body material such as dust and concrete.
Due to the size of the ~ ~ce~s~s it is i ~ f f ~ rll 1 t to detect and remove the foreign material. Such damage or contaminations make it ~iffirult and at times impossible for the shutter blocks to fit exactly . An exact f it is required to prevent concrete slurry leakage. The ~oining means for existing shutter blocks means the shutter blocks cannot be slid along the top of one another hence WO 95/12720 ~ 5 9 3 ~ F~ ~ 128 --it is ~liffirlllt to compensate for irregular ~oin~
in walls.
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 ~n;~hl in~ reinforcing rods to be quickly a~d firmly fixed in place. This will enable a quick and ~ffir1~nt method of concrete construction.
Other ob~ects and advantages of the invention will be apparent from the following description.
In one aspect, this invention provides for a shutter block, the shutter block including two regularly spaced shutter walls, each shutter wall has a cnntinllml~ ridge on its top and a cnnfin~
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.

2~ r~ l28 A8 shown in Figures 1 to 4 of the drawings the shutter block consists of two regularly spaced shutter walls 1, 2 of equal similar dimensions.
The int~rn~l face of each of the shutter walls 1, 2 includes a plurality of similarly dimensioned and dove-tail shaped Anrhr~ri n~ 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 ~oined 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 c~nt;nlltnl~ ridge 9 or rnnt;nllr~u~
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 Cnnt; nlll'Uf~
ridge 9 is of such a proportion that it f its in the cr~nt;nl~n~ recess 10 of a similar shutter wall above or below.
The outer face 11 and end face 12 of each shutter wall 1, 2 are preferably coLLu~c.ted.

The web 3 ;nr~ four similar sites 16 for the fixing of reinforcing rods. The sites 16 include lugs 17 which can be twisted to an open position 80 that a reinforcing rod of smaller diameter than the recess formed between the site~
16 and lugs 17 can easily be placed in the reces~.
The lug 17 can then be twisted back to the closed position, as shown in Figures 9 and 11, 80 the reinforcing rod is fixed in place. It should be appreciated that there may be variations in the number and rl A~ L of the sites 80 long as there is at least one site on the top and bottom of the web 3.
The web 3 is ~urther configured to include two larger recesses 19 and 20 for fixing one or more reinforcing rods tnot shown) to enable a bond be~
to be f ormed when the space between the shutter walls is filled with concrete. Any reinforcing held in larger ~ ~cesses 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 (Figures 5 to 8) has a single ridge 14 or a single anchoring recess 15. Where a divider 13 has the single Anrhnri n~ ridge 14 on its bottom face it has on its top face the single ~ WO9r7/12720 ~ J~ rl~7 ~7nrhr~r;n~ recess 15. The single ~nrhnr7n~ ridge 14 i8 of such a proportion that it fits in the single Anrh~7rin~ recess. The side faces 23 of the divider 13 nre dove-tailed 80 that they are an insertable f it into the dove-tailed grooves 4 of a shutter wall. The divider 13 can be inserted ~o that the single ~nrhr7ri77~ ridge 14 on the top of the divider 13 LU~ 7~0ndS to the c~7nt i n"r7u8 ridge 15 on the top of the shutter wall . Another option is f or the single anchoring recess 15 on the top o~ a divider 13 to CG ~ ~olld to the continuous recess on the top of a shutter wall.
In use a shutter block is formed by positioning at least one web in a mould, before two shutter walls are formed by heating poly~7 Ly . ~
balls placed in the mould. A divider is formed by heating a mould filled with poly~Lyr ~ e beads for an end wall.
In Figures 12 to 15 is shown an example of corner shutter block 24. This construction of blo~k 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 crnf i ,777rAtion to be b~ilt 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. simi 1 ~r~y the upper edge 8 has a ridge 29 while the lower edge 30 has a Lary recess 31.
In Pigures 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 i8 to be situated. In this situation the edge 33 of the unit 32 is aligned with an outside wall of the floor slab. Concrete can then be s~Le,ed~d off level with the top surface 34 of the unit 32. Tlle inner face 35 of the unit 32 is 2,uy~oLLed by spacers 36 which in this example are also ~u--~,LLu~:Led 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.
In use after a floor slab has been poured in situ a plurality of the shutter blocks are positioned in place leaving space6 for windows and doors. These spaces may be relatively easily formed to plan dimensions by cutting the polystyrene material as required. Dividers are ~ WO95/12720 17$930 . i F~~ La~
positioned where n~c~sary to close off any open ends of the blocks.
After reinforcing is placed in position and tied down as required the space between the walls of the blocks is filled with an a~uy~late cementitious mix . The ~ ri flr and interior can then be f i n ~ ~h~d of f with an outer plaster or similar coating as required or by the pl~r L of an interior lining like gib-board on the inside shutter wall.
In use the erected block walls can be stâbilised by reusable braci:ng formed from galvanised iron metal sectio~s which are mounted alongside an inner f2ce of the erected walls with angled sections tied or braced down to the f loor slab and fixed by dyna bolts or the like to the f loor pad .

It is possible to use the shutter block for a range of constructions or structures which include concrete wall6 , these include r~R ~ n~ i A 1, commercial and industrial b~ i 1 rl 1 nqç: .
It is rn~R;h~ that by r ' inin~ all of the above ~ c to produce a shutter block which may be used with reinf orcing rods in concrete construction .
It is to be Ulldl~ l Lood that the scope of the invention is not limited to the ~ rri hed -~i c and therefore that numerous variation~
and ~ifiratinnçt may be made to thege: ~ ~1 Ls without departing from the scope of the invention ~18 set out in this sp~rif~ration and the ~ d claims .
The int~rn~l face of each of the shutter walls 1, 2 includes a plurality of similarly dimensioned and dove-tail shaped Anrhr~ri n~ 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 ~oined 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 c~nt;nlltnl~ ridge 9 or rnnt;nllr~u~

Tlle inner face 35 of the unit 32 is 2,uy~oLLed by spacers 36 which in this example are also ~u--~,LLu~:Led 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.
In use after a floor slab has been poured in situ a plurality of the shutter blocks are positioned in place leaving space6 for windows and doors. These spaces may be relatively easily formed to plan dimensions by cutting the polystyrene material as required. Dividers are ~ WO95/12720 17$930 . i F~~ La~
positioned where n~c~sary to close off any open ends of the blocks.
After reinforcing is placed in position and tied down as required the space between the walls of the blocks is filled with an a~uy~late cementitious mix . The ~ ri flr and interior can then be f i n ~ ~h~d of f with an outer plaster or similar coating as required or by the pl~r L of an interior lining like gib-board on the inside shutter wall.
In use the erected block walls can be stâbilised by reusable braci:ng formed from galvanised iron metal sectio~s which are mounted alongside an inner f2ce of the erected walls with angled sections tied or braced down to the f loor slab and fixed by dyna bolts or the like to the f loor pad .
The exterior wall of the blocks being tied by wire ties to the inside bracing to for7~ a rigid 7 ' for a concrete pour in the blocks.
The ~hutter blocks for7n a ~Llu~Lule which can with ~ .. , h and bracing }~e used to create two ~torey ~Llu~_Lul~: as well ns a single storey r~ Ll u.: L ul ~ .
It is possible to use the shutter block for a range of constructions or structures which include concrete wall6 , these include r~R ~ n~ i A 1, commercial and industrial b~ i 1 rl 1 nqç: .
It is rn~R;h~ that by r ' inin~ all of the above ~ c to produce a shutter block which may be used with reinf orcing rods in concrete construction .
It is to be Ulldl~ l Lood that the scope of the invention is not limited to the ~ rri hed -~i c and therefore that numerous variation~
