Description

A modular waU assembly and method for This invention relates to a modular wall assembly, in particular for use with concrete permanent walls used for ecoThuildings.

Traditionally walls for boundaries, dwelflngs and commercial purposes have been built using wood, bric.k or stone and the construction of such walls has been carried out by skilled tradesman.. However, the construction process is slow, costly and hntpered by poor weather conditions, Also traditional construction techniques can be dangerous, especially when using heavy tricks or stones and may also be detrimental to. the construction workers health, for example skin dise.se associated, with skin contact with mortar. There is. also a considerable amount of wasted materials when using the traditional techniques for example mortar waste or cut bricks.

Concrete is a highly versatile material that is used in many forms of man-made structures from bridges to dwellings. It is a strong, extremely durable, sustainable, low maintenance and highly affordable material which is quick and easy to apply, making it a desirable alternative to the more traditional materials used in the past. Its resistance to fire makes it particularly suitable for use in highly populated areas and for structures used in our every day lives. It is also remarkably environmentally friendly. For example, it is generally locafty produced, saving on transport costs and has an energy efficient, production process that is relatively low in 002 emissions. (when compared to some other materials e g quarrying of stone) Further, it ha5 an oxceflont theimal mass enabling the maintenance of internal temperatures of a building and reducing the energy needs for the building he. minimising the use of heating and air conditioning, thereby saving energy consumption over the lifetime of the building. This consequenfly reduces the cost to the habitant of a dweUing, or user of a commercial property.

The aihedo effect is another beneficial property cf concrete, whereby light S is reflected from the surface of concrete resulting in less heat being absorbed by it. This consequently reduces the heat island effect and consequentially further reduces the energy required, for us.e in air conditioning. The ever increasing cost' of energy makes concrete a desirable material to LSP in constwction due to it's energy saving charactedsti'cs.

The ab.overnantioned benefits of using concrete. for the, wails in buildings is well known, making the' material hghly desirable foreco-huHdings However, concrete is generally deemed to be aestheUcally displeasing to the. eye, and therefore is not always readily welcomed for certain applications. The aesthetics of a concrete waU can be improved by the application of panels applied to existing concrete walls.

n WO 99 /43904 the panels were used as moulds and are left in situ to provide extra reinforcement. However to construct such a wall, the panels need to be secured in a suItable foundatlon and props are required to ensure the panels remain in the correct position whHst the concrete harden's. Any misalignment of the props, due to bad weather or human error, has a negative consequence to the orientation: of the wall, for example the wall could ha set oW vertical. This is especially problematic. on sloped. surfhcos. Furthermore, the chipboard panel may need a protective layer applied thereto, or a layer that is more aesthetically pleasing to the eye. This would also apply if the material was to be made of metal. Therefore, the. panet a not only difficult to tnstafl, hut takes further time to provide the required surface finish.

Concrete moulds of the type mentioned i Wa 99 /43904 have a first and second panel separated by a spacer. The spacers are usually fixed between the opposing surfaces cf the two panels. However, this. is problematic since such panels ae constructed i.n a factory resulting in the need for a bulky structure to be transported. the desired site, which can be costly and inconvenient when placing on site..

Wa 2005/01494$ overcomes this problem by having a three part hinged spacing arrangement. The hinge arrangement enables the panels to he.

reconfigured for: storage and transport prior to use. However, the hinge is a compheated arrangement formed of Lost'y compononts Further, tim panels are made of polystyrene and as such are untreated leaving. (herr open to the elements and susceptible to vandahsm. The panels are therefore required. to be rendered and this addition& further process of cladding or tiling the external surface is time-consuming and costly and is best carried out by a skilled labourer.

The energy eFficiency of a concrete wall can he improved further by inserting a cavity within the concrete. It is known to insert tubular members between the two parallel panels prior to inserting the concrete between the panels, but this can complicate the construction of the wall, consequently increasing the time arid the money for ts installation This also requires a skified tradesman. to carry out th.e work..

The present ihventiort is derived from the re&isation that there exists a need to provide a simplified waD assembly for use in eco-buikling that maintains.

the benefits of known concrete arrangements whUst easing constrç:con of the waD and improving the integrity of alignment and strength f the walls. The 5. assembly also enables cavity w&Us to be constructed by a lbwskiflled person in a fast! reliable and easily reproducible manner. The assembly is also safer compared to traditional techniques since heavy stories or bricks are no longer needed to be placed by hand and mortar no longer needs to be touched since the concrete is filled mechanically. There is also less waste associated with the construction, process of the present invention since the panels are precision made and the precise amount cf ready mix concrete can be calculated and ordered to site.

Refining firstly to Figure 1, there is shown a modular wall assembly 1 having a first and seccnd planar panel 2a, 2b separated in a pa:uel arrangement by a spacing means a. The respective a ide edges of the panels 2a 1.0 2b are in alignment. The adjacent. surfaces of the. waU assembly are, the internal Eurfaces 4a, 4b of the panels' 2a, 2h which come into contact wfth the settable concrete 5 that is apphed there-behceen. The panels 2a, 2b are left in situ and provide a small reinforcement effect,, although the majority of the strength is borne by the set concrete 5 contained the'reThetween.

The spacing means 3 comprises three parIs 6, 7. 8 as shown in Ficu.re:s 2a to 2c, The first part 6 extends from the internal surface 4a of the first panel 2a and attahe'd thereto, the second part 7 xtends from the internal surface 4b of the second panel 2h and attached thereto and the third part 8, being a linking member or ccnnectir'ig clip 9, is configured to extend between the free end. of the first and second parts 6, 7 so as to maintain a spaced relation between the first and second panel 2a, 2b i:n a face. to face arrangement. Therefore, a predetermined distance is maintained between the first and second panel 2a, 2b. The spacing means 3 is arranged substantially perpendicular to the planar 1$ surfae 0 th first and SCQ nd pane!

portions Ma, 14b extending pependlcutir to the longitudinal ads of the elongate tlern.ent 1.3.. The connector cUp 9 has a substan.tiafly Ushaped cross section. The internal edges cf the arm portions 14a, 14b. are terminated by a flange or protrusion 15a, 1Gb extending inwardly towards each other. The first flange 15a of the clip 9, and the Up ha and recess 12a of the first bracket 6, are co-operable; and the. second flange 16b of the clip 9, and the lip hlh and recess 12b of the second bracket 7, are co-operable Therefore the first arm portion 14a of the connector clip cooperates with the first bracket 6 and the second arm portion 14b of the connector clip cooperates with the second bracket 7. When connected, the resulting spacing means 3 acts as a brace member located between the first and second pand 2a, 2b. When the panels 2, a are to be separated by a predetermined distance, the flanged ends of the clip 14a, 14b are inserLed paQ the Up' Ia, 11 b and are rec ved m the respe tive recesses 12a. 12b of the brackets in a snap fit. The Up, recess and flange arrangements prevent, separation of the clip 9 from the brackets 6, 7 in the reverse direction of I'S motion so as to form a locked state. An unlocked state may only be achieved if the flange or protrusion iSa, 15b cf the dip 9. is forced to extend past the respective lips ha, ilh of the respective brackets 6, 7, Therefore, on application of a tool, the dip 9 and brackets 6, 7 may he detached prior to the insertion of any satiable concrete between panels so as to reposition panels if necessary.

The distance between the first and second panel 2a, 2b is determined by the width of the clip and bracket arrangement. To optimise the locked state, the recesses. 12a, 12h of the first and second brackets 6,. 7 receive a correspondingly shaped protrusion or flange 15a, 1Gb located at respective ends of the connector clip 9. The clip 9 and the brackets 6,7 are formed of a resilient material that also has the strength to maintain the: desired distance between the first and secpn.d panel 2a, 2b for example plasftc or a. composite materiaL.

FigUre 3 shows that two brackets 6, 7 are appHed to the. inner surfaces 5. 4a, 4h of the. panels 2a, 2b in a spaced apart arrangement such that the first bracket 6a for the first panel 2a is pplied adjacent a first side, edge of the panel and a second bracket Sb on a first panel 2a is ositioned adjacent the other side edge of the panel 2a, although the number of brackets per panel need not be rnted to two and the position of the brackets may differ in vertical height if aesirod, howcver the hiacket arrangement must correspond to the bracket arrangemenLon the partner panel to which ftis to be connected The panels 2a, 2b are finite in size, tierefore. for wail lengths that are greater than the width of a panel multiple panels are to he installed side by side Therefore, Figure 3 also shows a secondary bracket 1.6 forming half of the secondaryfixing means 17, whercby.a tang 16 extending past the side edge ate neighbour panel is to La inserted within the channel. 19 of the secondary bracket, so as to fixably secure the side edge of a first panel to a side edge of a second adjacent panel 2c. The tang 18 is moulded to the internal surface 4a of the first panel and the secondary bracket 16 is. moulded to the internal surface 4c of the second neighbour panel 2c. As shown in Figure 4a and 4b, the tang 16 is an elongate, member, the free end ISa of which extends pi5t the side edge of the panel 2a to which it s affixed. The other end s attached to the internal surface 4a of the panel 2a (or alternatively is an integral part thereof).

The free end of the tang is terminated by a barb 20 and is configured to permit insertion of the teng 1 through the channel 19 of the secondary bracket 16 on apphcation of a force in a first direction, but once the barb 20 extends past the wmote and 19a of the secondary bracket 1$, it returns to its un-biased state and extends. past the outer waR 19h of the secondary bracket 16 so as to prevent extraction of the tang 18 from the secondary bracket 1.6 on application of movemet in a secon.d direction opposing the first direction, as shown in Figure 4b.

Figures 1 and 4 also show the use of a co-operable tongue 21 and çroove 22 arrangement enabling the panel 2a of a first mcduiar wall assembly I to be configured to receive a corresponding side edge of a panel of a further modular wall assembly is. Ultimately, the tongue 21 and groove 22 arrangement permits a tight joint between neighbouring panels 2a, 2c and m.Inimises gaps lher&between:w(d) would allow concrete to escape. The tcngue2l and groove 22 arrangement is applicable to all the edges of the panel and as such is beneficial for arranging, the panels 2a, 2c in. a side to side or in a stacked arrangement. For example, in the side to side assembly shown in Figure 3, the First panel 2a has a tongue 21 which co-operates with a groove 22 of a panel, of a second, adjacent wait assembly 2c. The tongue 21 extends continuously along a significant length of the side edge of the first panel 2a but this need not be the case, whereby an array of spaced tongue portions may instead be implemented along the edge of the panel, the tongue 21 is the. male part of the arrangement and the groove 22 the female part,, whereby the. two parts are co-operable The groove 22 complrnents the shape of the tongue 21 such that a snug filet The tongue therein Is enabled. 9gw. 1 shows that the top ton tie,qende, the en*e width of a first edge (Pfl edge) of the panel 2a and the opposing: edge (base edge) has a grooye with axtetids alonG the en*etyotthewidthdf theplcwJ;attts!u9h1Ssneed notbethecase,and:the tongue and groove may extend along only part of lbs width of the fl$,.

The top cap membe.r 23 is of ue to protect the concrete 5 and provides an aesthetically pleasing terminus to the wall 25.

Figures Ia and lb shows. the corner wall assembly 26 whidh is to be implemented with the hefore-described planar wall assembly. it comprises an inner corner wafl panel 26a spaced apart from an outer corner wall panel 26b, The corners create a 90 dogee angie, hut ofhe angles may be mplemented if desired. The inner corner panel 26a has a first portion 2/a and a second portion 27b positihned substantially perpendicular tO the first portion 27a and the cuter corner panel 26b has a first portion 28a and a second portion 28b positioned substantially perpendicular to each other, whereby the first portions 27a, 28a of respecUve panek and the second porhoris 27b 28h of wspechve panels Iba, 2Gb are configured in a parallel arrangement.

Sim.ar to the standard planar wall panel arrangement the inner corner wall panel 26a has a groove 22 at one side edge and a tongue 23 at the other side edge. The. outer corner wall panel 2Gb also has this arrangement, whereby at one end of the corner wall assembly the parallel portions have the same termination type. The secondary fixing. means 17 will also be used to further ensure the corner wall assembly and the planar wall assembfles remain in a secured position. Further, the clip 9 and bracket 6, 7 arrangement maintains the desired distance beiween the inner corner wall panel 26a and the outer carrier wall panel. 26b. The corner wall panel assembly 26 is further joined to the end of a linear wall panel assembly 1 with a spring dowel (not shQwn), or other suitable fixing means.

The outer surface 29 of the panels 2a, 2b., i.e. those which are positioned remotely from the concrete, are finished to look like a desired material. For 5. example. Figures $a and Sb show the composite. face of the wall with a brick effect, Alternafive effects may be implemented, for example stone or wood., The outer surface 29 is weatherproof removing the need for a cladding (or other) process to be applied. In contrast, the internal wall 4a of the. panel 2a is finished with a plain yet roughly textured surface that encourages the concrete 5 to adhere to the internal surfae 4a of the pane.l 2a.

Figures 9a and Yb show the adjustable foot arrangement 30 of the waR assembly 1 whereby a base plate 31 is positioned at the base of the foot and a panel receMng portion 32 is configured at the top of the foot 30 with an adjustor 33, for example a screw and thread arrangement 33a, located there-beteen.

The pan receMng porUon 32 has a slot 34 for rcceivin.g the bae of the weB assembly 2a and for tightly holding, it in place. The screw and thread 33a of the adjustor 33 is rotatable enabling variation in the &tance. between the base plate 31 and the pane] receiving portion 32 so as to level the wall assembly when it s constructed on uneven terrain..

Figure 10 shows how the walt assembly is received in the slot 34 of the panel receiving portion 32.

Simflar to the need to make the top of the wall aesthetically pleasing to the eye, when a wall is. not intended to he joined, to another wall assembly an end cap 35 may be applied as shown in Figure 11. Similar to the top cap 23', this is an elongate portion having a sutstantially ftshaped crosssection so that it can be secured to the end of a waD assembly. The end cap 3.5 prevents the escape of settab.le concrete from between the fIrst and, secopd panels. The elongate ends of the end panel either have the tongue 21 or the groove 22 arrangement to be applied to correspcnding grooves 21 or tongues 22 of the planar 1 or corner watt panels 26. Whilst the lower region & the end cap 35 will have a groove, the top end may have either a tongue Zt or a groove 22 as required and shown in Figures 12a and 12b.. The end cap 35 iS secured to the assembly with a spring dowel (t shown). AlternatIvely, other fixing means may be suitably appiled, e.g. a. rivet. In an alternative arrangement, the, end cap. may be enclosed at its top end as shown hi Figures iSa and 13b.

Fig ure 14 shows the modular aspect of the wall assembly and, importantly, the stackable nature of the panels 2a, 2b. herein the top edge of a panel:j configurable to receive a bottom edge of a panel in. a further modular wall assembly lb. Therefore multiple wall assemblies are coupled together. The foot 30 i's at the lowermost part of the wall arrangement. The grooved end 23a at the base of the panel lower e'nd is inserted into the slot 35 of the panel receiving portion 32 of the foot 30. The walls of the slot 35 extend along the internal and external surface of respective panels 2a, 2b. The connector dllp 9 is 20' then applied by placing the clip over end portions of the first and second bracket' so as to enable' a. snap fit. The clip Is placed over end portion's of the first and second bracket via movement of the clip in an ipwards or downwards duecUon parallel to the planar surface of the panels and subsequent to the panels' being placed in spaced relation and at the predetermined distance to he maintained, Alternafively, the connector clip 9 can be appUed. prior to the panels 2a, 2h being received by the slot 35 of the foot 30. A second panel assembly lb may then be applied to the top edge of the first panel assembly 1, whereby the lower end grooves of the second panel assembly lb receive the. respective upper end (top) tongues of the first panel assembly 1. The connector cUp. 9 is then applied so as to maintain the distance between the planar panels of the second pane]. assembly. Alternatively, the, connector dip 9 can be applied prior to mating the tongues 21 of the first panel assembly I with respective groo'.es 22 of t:he second panel assembly lb. At the top of the stacked wall.: and once the desired wail height has been achieved, a top cap 23 ie positioned. The end result is an instantly installed seamless wall structure.

As shown in Figures 15a, 15b, 1.Sc and 15d, in use, the feet 30 incorporating the panels 2a, 2b are inserted into a trench. The panels 2a, 2b are then locked into position with the connector clip 9 and the: feet. 30 are configured 15: to the desired height sc as to level or align the arrangement Concrete 5 is then poured into the trench up to the top of the trench,. Concrete 5 is also inserted between the panels 2a, 2b untIl a point just below the top of the panels 2a, 2b.

The concrete foundation is then given 48hrs to set. Once the foundation has set, a second rcw of panels 2c, 2d are stacked on top: cf the first row, ensuring that respective tongue 21 and grooves 22 cooperate appropriately. The connecting dips 9 are then inserted in respective brackets 6, 7 and secondary fixing means 17 are applied so as to lock the sewnd row of panels to tho fust row of panels. This continues until the desired height of the wall is achieved.

Concrete 5 is then poured between the panels 2.a, 2b until it reaches just below the top of the top-most row.

In both cases the external surface of the panel and the panel material itself are an:htegral unit lie. the brici effect is not a result of a separate coating or layer being applied to the panel after the panel has been. installed. This arrangement enables the panel 2a. to remain in situ so as to provide additional 5. strength to the structure, whilst removing the need to. apply a finishing layer to the outer surface of the panel which is a cumbersome and time consuming process.

The textured surface offers a variety of benefits to the resulting wall. For example the plastic panels are stronger due to the textured formations on the external surface which are shaped as b'ckwork or stone blocks This textured formation ultimately provides a backbone which reinforces the structure of the pane].

The resin or paint finish adds an additional waterproofing to the panels to prevent the ingress of damp inside the wails. It also pcevents sun bleaching or weathering, protects against frost and extreme summer he*t contracting and expanding effects on the plaslic, allows graffiti/damage to be covered over with the original stone paint and allows for owners to apply a change of colour to their façade depending on the current fashion trend.

As shown in Figures. 1.9a and lYb, the first panel 2a has a contoured side 20. edge at the front of the panel for, in use, being cooperable with a contoured sde edge at the front (or external side) of an adjacent panel Thetefore, only a part of the side edge of the wail panel needs to be contoured. This helps to align the adjacent fence panels improving the. modular nature of the panels. The contoured side cogo of the panel effectivcly del nes interloc king edges 43a, 43b to be interlocked with a cooperable interlocking edge of an. adjacent panel. This further improves the strength and integrity of the joint between the adjacent panels and the interlockIng brick design eisa hides or masks the joint between two adjacent panels. At least part of an edge of the first panel 2a therefore has a caste.Uated edge 43c rather than a ontinuous Unear edçe. whereby the joint or contoured side edge follows the shape of one end of a wail element.. The wall element my be at least one brick element. In the case of the. stone, surface effect, the wail element is a stone element and the contoured side edge follows the shape of the stone elements located on the external surface of the panel.

Figures l.a and lYb fLtrther show how the: protrusion 44 ci the casteffated edge is arranGed with channel 45 for receiving part of an adjacent paneL The protrusion 44 then exte Ms along a surface of the adjacent panel whereby the external surface 44a of the protrusion lies flush with the external surface 42 of the adjacent panel. Therefore, the part of the adjacent panel that. is received in the. Channel 45 of the protrusion 44 is non4extured and is a part of the panel that has a recess 46 that is cutaway by a thickness matching the channel wall of the protrusion. The prctrusion 44 haa the appearance of one end of a brick element.

ft is also shown that the connector portions are stHl utilised to lock the adjacent panels together, En figures 20a and 20b. the internal surface is shown to be smooth.

Various modifications to the principles described above would suggest themselves to the skified person For example, nstead of being integrally formed with the panel, the brackets and secondary fixing clip may be separate and distinct parts attachable to the internal surface of the panel by a fixing.
