Abstract

The method comprises building the wall horizontally before raising the wall to its in use upright position. The wall is made by being formed, possibly by casting, over support portions 28 each having a protrusion (76, Figure 8) in its foot that extends into what would be the base of the wall in use. The support portions may initially be attached to the wall using ties 30 but they are subsequently removable from the wall. The support portions may initially be used in the assistance of lifting and transporting the wall. The protrusions may taper upwardly and into the wall when the wall is in the upright position. Also claimed are the wall and the support portion.

Description

BUILDING IMPROVEMENTS

The present invention relates to a method of building a wall, a method of moving a wall, a method of construction, a method of building a house and a house.

Prefabricated buildings have been used for many years.

Typically they comprise reinforced concrete walls that are transported to the site and then erected. However, they are not pleasing in appearance and suffer from high heat loss and condensation. Consequently they are not a good solution to providing housing.

When building new housing incorporating bricks on the outside, the bricks are laid on top of each other. This requires great skill as the bricks have to be aligned with each other in the vertical direction to present a vertical flat face. Furthermore, the bricks in a horizontal row all have to be at the same level and the joints between two bricks in a horizontal row have to be located midway along bricks in adjacent upper and lower rows.

Consequently the laying of the bricks is time consuming and expensive. In addition, it is not possible to lay the bricks in inclement weather.

It is an object of the present invention to attempt to overcome at least some of the above or other disadvantages.

According to one aspect of the present invention a method of building a wall comprising forming a wall at an inclination that is transverse to what, in use, will be the upright position of the wall with at least one support position extending over at least part of the wall, the support position including a protrusion with the protrusion extending into at least part of what, in use, will be the base of the wall, the support position and the protrusion being removable from the wall with the method comprising forming at least part of the wall over the protrusion.

The method may comprise building a wall that includes a plurality of pieces with those pieces in use, being arranged to define a surface that extends inwardly.

The surface may extend substantially horizontally during attachment.

The pieces, during attachment, may be attached to the top of a support portion such as by adhesion.

The pieces may be spaced from each other. The fibres may be nylon and may be made to be less than 50 or less than or more than 1 cr more than 5 or in the region of 10 mm long.

The pieces may be physically connected to the support portion such as by indirect connections, for instance by ties that extend from the region of the pieces into the support portion. The ties may extend into a support layer comprising part of the support portion which support layer is spaced from the pieces. The support layer may comprise concrete such as lightweight concrete. The concrete may be cast in situ. Alternatively the concrete may be pre-cast and then brought to the location where the pieces are attached. The concrete may include reinforcement such as mesh.

The pieces may comprise bricks or stones or artificial stone or tiles. These may be more than 2 or more than 4 or in the region of 6 cm wide or more than 8 or more than or in the region of 15 cm long. They may be more than 4 or more than 6 or in the region of 10 cm deep.

An insulation layer may be included between the pieces and the support layer.

The pieces may be attached such that they, in use, when they extend upwardly and the wail is an outer wall, comprise an outer part of the wall. The wall may be assembled such that, in use, when the wall is an outer wall, the inner part comprises a plaster board.

The method may comprise forming the periphery of what, in use, will be at least one edge wall to include a recess extending along at least part of its length.

The method may comprise forming the wall such that at least part of at least one edge is other than straight, such as by forming that part in a castellated manner. The part that is other than straight may comprise the concrete layer.

The pieces may be attached over substantially the complete surface of the wall. The pieces may be attached such that there are gaps at at least one edge region.

The method may comprise forming the wall with at least one opening such as a door or a window. The method may comprise locating a lintel when building the wall. The lintel may be spaced from the other side of an opening in a direction transverse to the vertical when building the wall.

The method may comprise forming the wall with at least one suspension means. The suspension means may be detachable from the wall.

The present invention also includes a wail and support position, the wall having been formed at an inclination that is transverse to what, in use, will be the upright position of the wail with at least one support position extending over part of what, in use, will be the base of the wall, the support position including a protrusion extending into the wall, the support position and the protrusion being removable from the wall with at least part of the wall having been formed over the protrusion.

The present invention also relates to a method of moving a wall that has been built by a method as herein referred to. The method may comprise inserting lifting members beneath the wall, such as those of a fork lift truck, and raising the wall. The method may comprise reorientating the wall by lifting one edge region relative to another.

The method may comprise the pieces acting together when lifting the wall to assist in the rigidity of the wail.

The pieces may act together both to increase the compression resistance of the wall and to increase the tension resistance of the wall.

The present invention also includes a method of construction using at least two walls that have been built as herein referred to with the method comprising connecting the walls together. The method may comprise raising the walls to a vertioal position. The walls may be connected together to form a corner or side-by-side and generally in line or one on top of another. The method may comprise connecting at least one wall to a supporting surface, for instance by adhesive. The walls may include cooperating portions arranged to fit within each other, such as by a dovetail. The method may comprise causing cooperating portions on the support portions such as the concrete layer to fit with each other.

The method may comprise adding additional pieces in the region that the wails are joined to each other such that substantially the whole surface defined by the exterior of the walls is covered in pieces.

The method may comprise adding additional pieces that extend beyond the periphery of a wall.

The method may comprise causing at least part of the support portion that has had pieces attached to it by the method of Claim 1 to, in use, extend upwardly and to be located at a higher level than the level of those pieces.

According to a further aspect of the present invention a method of building a house using at least one wall that has been built by a method as herein referred to comprises clearing an existing house and constructing a new house with at least one and preferably several or preferably all enterior, preferably at least one interior of those walls on the foundations from where the house has been cleared.

The present invention also includes a house that has been built by a method as herein referred to.

According to another aspect of the present invention mortar comprises a mixture of cement, sand. and fibres.

The fibres may comprise nylon fibres. The fibres may be less than 50 or less than 40 or more than 1 or more than 5 or in the region of 10 mm long.

The present invention includes any combination of the herein referred to features or limitations.

The present invention can be carried into practice in various ways but several embodiments will now be described, by way of example, and with reference to the accompanying drawings in which:-Figure 1 is a schematic perspective view showing the different layers of a wall; Figure 2 is a schematic perspective view showing the means of lifting and supporting the wall; Figure 3 is a schematic perspective showing a wail in position; Figure 4 is a schematic perspective plan view of a corner joint between two walls; Figure 5 is a schematic sectional view of a house incorporating a wall; Figure 6 is a schematic plan view showing the location of the walls of the house; Figure 7 is a perspective view showing part of the wall being assembled on a former; Figure 8 is a view of what, in use, will be a support foot for the wall; Figure 9 is a view of the shape of part of the wall after the support foot has been removed1 and Figure 10 to 12 are a side, front and plan view respectively of a support bracket.

Figure 1 shows how a wall 10 is built up. A layer of prefinished plasterboard 12 is placed upon a support surface (not shown) Then a damp-proof layer such as a foil moisture inhibiting layer 14 is located on and secured to the plasterboard 12 by adhesive.

The next layer to be applied is a lightweight concrete layer 16 of 10 cm thickness incorporating two spaced stainless steel meshes 18 that reinforce the concreteS The layer 16 can be prefabricated or can be cast onto the previous layers. The layer 16 is secured to the layer 14 by adhesive or by the concrete attaching itself to that layer during casting. The concrete includes ties 20 embedded therein that extend upwardly from the concrete.

An insulation layer 22 or 10 cm thickness is located on top of and attached to the concrete layer 16 with the ties extending upwardly, through and beyond the insulation. A further damp-proof layer may be included between the layers 16 and 26, if desired.

Finally, bricks 24 are mounted on the insulation with a scree of sand. and cement onto the insulation layer 22 with the ties 20 being located in gaps between the bricks and attached to the support In a conventIonal way.

The gaps between the bricks is (which term herein includes stone) and artificial stone) filled with a mortar comprising a mixture of cement, sand and fibre. The fibre may be of relatively short length such as 10 mm. The fibre may be nylon. The mortar bonds with the bricks to provide a connection between the bricks that is not only strong in compression but is also strong in tension.

This is of particular importance as during the lifting of the relatively heavy wall, the wall may twist slightly.

The presence of the special mortar resists any tendency for the mortar to crack as well as assisting in maintaining the wall rigid. In an alternative embodiment (not shown) tiles are adhered to the insulation in place of the bricks with mortar being used, if required.

After the assembly has hardened the wall 10 is then ready for transportation to the site where it is to be erected.

The walls can either be transported in the configuration shown or they can be raised to extend upwardly. The base on which the plasterboard is assembled may include spaced parallel recesses into which the arms of a forklift truck can be inserted in order to raise the wall and load it flat onto a lorry.

As shown in Figure 2 the wall 10 includes removable spaced support brackets 26 that comprise arms 28 that are attached by ties 30 that extend into the concrete layer 16. The other end of the bracket 26 will be described later. The brackets 26 are bent at right angles to extend over the edge of the wall 10 to provide lifting portions 31. Cables 32 are attached to the portions 31 to allow a crane to pull the edge of the wail upwardly to reorientate the wall in a vertical or near vertical direction and to carry the wall to the required location.

When the wall is in position it is lowered and adhered to a prepared foundation for example by resin. The brackets 26 are removed from the wall 10 by removing the ties 30.

These ties 30 may be a sliding fit in the wall.

Alternatively they may comprise bolts which can be unscrewed from the wall.

If desired, the wall may be temporarily held in place with support bars or lines 34 as shown in Figure 3 that extend from brackets 36 on top of the wall to anchor points 38 at foundation level. These lines may extend from both sides of the wall.

Although the wall 10 shown in Figure 1 includes flat sides it will be appreciated that those sides, or parts of at least one of those sides, may be other than flat. As shown in Figure 2, the layer of bricks 24 that form the top of that wall include an angled edge 40 such that the top of that wall presents a pleasing appearance.

Furthermore, the top of that wall includes spaced recesses 42 in the plasterboard and concrete layers. Joists for use in supporting the roof or a floor above may be located in these recesses.

The wall 10 may also be assembled in a horizontal position to include openings for doors and windows, in which case the lintels can be laid at the appropriate locations and openings in all of the layers can be made for instance with the concrete layer by using appropriate formers when casting the concrete and, with the remaining layers, by cutting or preforming those layers with the openings.

When the walls are mounted in situ, the windows and doors can be attached. Alternatively, the windows and doors can be mounted prior to transportation of the walls.

The walls may also include trunking passages 44 for electric cables, as shown in Figure 1.

Figure 7 shows the base 60 of a former. The base includes spaced parallel channels in which the arms 28 of the support brackets 26 are located such that the upper surface of the arms 28 are flush with the surface of the base 60. The ties 30 extend up into the concrete layer 62 and possibly through the concrete layer 62. The concrete layer may be the first to be applied and may be moulded onto the former and around the ties with the subsequent layers previously described then being applied.

Threaded bolts (not shown) extend through and connect the ties to the arms 28 and these bolts can be removed when the wall is in situ by unscrewing the bolts.

The side of the former shown in Figure 7 is defined by part of the upwardly extending surface 64 of the portions 31. A former (not shown) is located between the surfaces 64 such that that side of the concrete is planar.

The other side of the former is defined the support feet 66 located at the other end of the arms 29 as shown in Figure 8 and 10 to 12. A former (not shown) extends between adjacent feet 66. The length of the feet along the side of the wall may be 300mm and the distance between the feet may be 300 or 600mm.

The side of the wall may be planar and defined by the inwardly facing surface 68 of a plate 70 of the feet and the inwardly facing surface of the former.

The support foot also has a key 72 that extends inwardly from the plate 70 and upwardly from a bottom plate 74, the upper surface of which plate 74 is flush with the base of the mould. The concrete is moulded around the key 70 and the key extends downwardly and outwardly from an upper ridge 76 which ridge 76 is inclined downwardly from the plate 70 and Inwardly to terminate at the inner portion of the bottom plate 74.

Part of the plate 70 is arranged to extend above the concrete layer which may assist in directly retaining or supporting one or more additional layers. In use, the plate 70 or bottom plate 74 or the key 72 or any configuration thereof may assist in supporting the wall during transport or when lifting or lowering or angling the wall or any configuration thereof.

It will be appreciated that, once the wall is in-situ it will be necessary to remove the support brackets 26. To assist in this spacers (not shown) may extend downwardly from the wall adjacent to each plate 70 with, for example the spacers being of 10 or 12mm depth and the plate being of 8mm depth. Thus the spacers will support the wall and the plates 70 are clear of the surface that supports the wall. The spacers may be moulded integrally with the concrete or fixed to the wall subsequent to forming the concrete forming part of the wall or when the complete wall has been formed.

The inward inclination of the key assists in it's withdrawal from the concrete. In addition, the plate 70 includes inwardly converging sides 78, as shown in Figure 12, which assists in the withdrawal of the support brackets.

To further assist in the withdrawal, as shown in Figure 11, lugs 80 extend from either side of each bracket. A cam or other mechanism or lever can co-operate with the lugs to urge or force the base of the bracket away from the wall.

Figure 9 shows the shape of the cavity in the concrete when the key has been withdrawn. In use, this will be filled In.

Figures 4 show the joint that is made between two walls 1OA and lOP that extend at right angles to each other.

The wails are each made such that their layers making up their sides are not co-extensive. Accordingly, the plasterboard layer 12A extends to be adjacent to the concrete layer 16B and the edge of which layer 165 is against the layer 16A. The insulation layer 22B extends beyond the concrete layer l6B to go over the end of the concrete layer 16A and the insulation layer 22A. Suitable ties (not shown) may connect these layers.

To finish off the corners, bricks 46 are laid in place on site with ties (not shown) 48 connecting those bricks.

In addition the walls 10 meeting at corners they may also meet in line with each other. In this case joining bricks may be laid on site.

Alternatively or additionally, the walls may be castellated, at least along the cooperating concrete layers, if not more or all layers such that the walls can dovetail into each other. Such dovetailing may also be used for at least one or all layers at the corners, in a line or one wall on top of another.

The walls 10 may extend the complete depth of a room.

Alternatively two or more walls may be mounted one on top of the other to achieve the depth of a room or, alternatively or additionally, to extend the depth of a building having at least two floor levels.

As shown in Figure 3, the top of the wall 10 may include a recessed edge 48 running along its complete length. A further wail (not shown) may then be located upon that wall 10 with the further wall having a recessed edge on its opposite side such that the two wall edges mate together. Ties or adhesive or both may be used to secure the walls together. Alternatively joints may be supported by the edge 48.

Figure 5 shows how the bricks 24 of a wall 10 extend down below the concrete layer 16 of that wall. In this way the bricks of the house are supported on a lower base 50 than the base 52 of the concrete and the floor of the house.

The lower bricks in the wall, beneath the base 52, may be added after the wall has been located in place.

Figure 6 is a plan view of a house. The outer walls 10 are constructed and assembled as previously described.

The house also includes Internal partition walls 54 that are connected to each other and to the wails 10 in a conventional well known manner.

The house that is built with the above described walls is primarily although not exclusively intended to replace houses that are in a bad state of repair and which were built as low cost housing for instance as sheltered housing. The existing house is demolished when they become vacant and the new house is erected in their place, possibly using the existing foundations and amenities.
