    Method for renovating a facade, element for use therein and method for manufacturing the element
    The present invention relates to a method according to the preamble of claim 1.
    Such a method is not known in the art. Up to now, when exterior facades are due for replacement, renovation of buildings has been constructed in the original manner, as described in British patent application GB 2 177 444. This means that the facade is completely rebuilt. This can only be carried out when the weather permits that work.
    A completely different solution is proposed in FR 2 743 101 where an insulating retention wall is mounted on an existing facade. The disadvantage of this method is that the strength of the original wall must be sufficiently strong to support the weight of the new wall, which is generally not the case. The finish and appearance of the additional wall are also not suitable for outdoor use.
    There is therefore a need for a method that does not exhibit this disadvantage.
    The invention now has for its object to provide an improved method of the type mentioned in the preamble.
    In particular, the invention has for its object to provide a method of the type mentioned in the preamble which makes it possible to replace an outer leaf in a quick and simple manner.
    It is also an object of the invention to provide a method for manufacturing such an element.
    It is also an object of the invention to provide an element for use in the method.
    In order to obtain at least one of the aforementioned advantages, the invention according to a first embodiment provides a method comprising the features of claim 1. This method has the advantage that a façade can be renovated quickly and easily without causing a lot of inconvenience to the users of the building. Users of the building can possibly stay in the building during the renovation because the work can usually be carried out within a day or a few days.
    The placement of the insulating layer against the bottom, which is a construction element of the new outer sheet, for example chipboard or the like, a very good insulating layer is obtained with a simultaneously high structural strength. The bottom comprises at its peripheral edges (also referred to as side edges) walls that are remote from the bottom. The insulation layer is formed in the space formed by the bottom and the walls, so that it is well enclosed and provides optimum insulation.
    It has also been found that the method according to the invention provides the option of leaving the part of the existing outer leaf lying at or below ground level. This is even possible when the original outer leaf is largely outdated. Therefore, excavation work does not have to be carried out. The replacement outer blade can be mounted on or above ground level against the original inner blade.
    Such a synergistic effect is completely unexpected. In the case of the renovation method used so far, it is precisely the part of an outer leaf that is below ground level that has to be replaced.
    It is preferred that the method comprises the step of airtight sealing of a cavity formed between the prefab outer leaf and the inner leaf. This provides a further improved insulation. In combination with a moisture-resistant film, it will be possible to effectively prevent moisture from breaking through.
    In particular, a method is preferred in which the support bracket comprises a torque leg to be attached to the inner leaf and a support leg remote from the coupling leg, which support leg comprises a cam for receiving a recess provided in the prefab outer leaf. This allows a simple and fast alignment and positioning of the outer leaf on the facade. Furthermore, the ridge prevents the prefab facade from shifting after installation.
    In order to obtain an accurate adjustability of the positioning of the prefab facade, it is preferred that the cam is slidably coupled to the support bracket for varying the distance between the inner leaf and the cam.
    A clean and durable outer sheet is obtained when the finishing layer is formed from stone strips, glass, or natural material parts such as wood.
    The method is preferably characterized in that it comprises the step of removing an original outer sheet above ground level and attaching a prefab outer sheet to the inner sheet, and sealing a gap airtight between the original remaining outer sheet and the prefab outer sheet . This provides optimum insulation, so that a house of energy class A can easily be obtained.
    A further improved insulation is obtained by a method which comprises the step of removing a floor element extending through the original outer sheet, for example a storey floor, and arranging the prefab outer sheet while forming a cavity. By placing a prefab outer leaf that is located on both a part of the inner leaf below the floor element and a part of the inner leaf that is situated above that floor element, an increased stability of the total facade is obtained.
    A further specialization of the invention is obtained in that it comprises a method for manufacturing an outer sheet for use in the method for renovating a facade, comprising the steps of: providing a box-shaped element with a bottom and side edges of the bottom exposed walls; placing the edges of the walls remote from the bottom against a counter mold to form a closed space formed substantially by the bottom, the walls and the counter mold; and filling the space with an insulating material. Such an outer sheet has the advantage that it is very easy to check whether the insulation material is optimally distributed in the outer sheet. After removing the box-shaped element, which actually forms the basis of the outer leaf and is therefore also referred to here as "outer leaf", the side facing away from the bottom is open and the insulating material is immediately visible. Any unfilled spots can still be filled with insulation material, if necessary.
    A further advantage is that the box-shaped element can be provided with piping, for example for electricity or similar utilities, and can subsequently be placed on the counter jig. The insulation material can then be introduced.
    After curing, as required when using, for example, polyurethane foam, the box-shaped element can be removed from the mold and it can be checked whether the insulation material is sufficiently distributed. During curing, the finishing layer can preferably be applied to the side of the bottom remote from the insulating layer, which means a large time saving for the production.
    It is therefore preferred that the manufacture of the outer leaf comprises the step of placing pipework in the space defined by the bottom and walls for the purpose of, for example, utilities; filling the room with insulation material; allowing the insulation material to cure if required; and removing the box-shaped element from the counter jig.
    Therefore, it is also preferred that the insulating material is a foam material, in particular a curing foam, in particular a foam formed in situ, preferably a polyurethane foam.
    A suitable positioning of the outer leaf on a support bracket connected to the inner leaf is obtained in particular when at least one of the walls comprises a recess for receiving a cam of a support bracket.
    As mentioned above, it is preferred that the outer leaf, in particular that the box-shaped element, comprises a finishing layer on the insulation material side of the bottom.
    A suitable attractive and durable finish is obtained when the finishing layer is formed from stone strips, glass, or natural material parts such as wood.
    The invention also relates to a prefab outer sheet for use in a method for renovating an outer wall according to the invention, formed from a base element with an insulating layer formed against a construction surface forming an outer surface and between walls of walls separating from side edges of the sheet and a finishing layer provided on the outer surface of the base element remote from the insulating layer.
    The invention will be explained in more detail below with reference to a drawing. The drawing shows in:
    FIG. 1 a schematic vertical section through a wall according to the invention,
    FIG. 2 a schematic vertical section through a wall with a window sill according to the invention,
    FIG. 3 is a schematic vertical section through a wall with a roof construction according to the invention,
    FIG. 4 a schematic horizontal section through a wall with a frame according to the invention,
    FIG. 5 is a schematic representation of the manufacture of a basic element for use in an outer sheet according to the invention.
    In the figures, the same parts are indicated by the same reference numerals. However, the parts necessary for a practical implementation of the invention are not all shown, due to the simplicity of the representation.
    FIG. 1 shows a schematic vertical section through a facade formed of an outer leaf 1 according to the invention and an inner leaf 2. The inner leaf 2 is a conventional wall formed of, for example, concrete, sandstone blocks or the like. The inner sheet 2 has a sufficient structural strength to support a storey floor or roof construction on it. The inner leaf 2 is supported on a floor 3 which is supported by a foundation wall 4.
    The facade also comprises the outer sheet 1, which in the embodiment shown is formed from a basic element 5 with a first outer surface 6 and a second outer surface 7. The outer surface 7 faces the inner sheet 2 and is spaced therefrom. For example, slats 8 are attached to the outer surface 7, as further indicated in FIG. 4, to which a finishing layer 9 is attached. In the embodiment shown here, the finishing layer 9 is made up of an eternite plate 10 on which stone strips 11 are arranged. Connection of the stone strips 11 to the eternite plate 10 can suitably be obtained with an adhesive.
    With the invention, a facade is obtained which has an outside 12 located on an outside of a building and an inside 13 located on an inside. The thickness of the prefab element is substantially equal to the thickness of the original outer leaf. As a result, the size of the building remains substantially unchanged, making the method according to the invention widely applicable. Nevertheless, a very well insulated building can be obtained with the invention.
    As in FIG. 1, a gap 14 may remain between an original portion 15 of an outer sheet and the prefab outer sheet element 1. This gap 14, as well as other gaps that are created around the prefab element, can simply be sealed with a polyurethane foam or the like, whereby a airtight seal is obtained. This improves the insulation value of the building. This also protects the support bracket from the environment, eliminating a possible cold bridge.
    FIG. 2 shows a schematic vertical section of a prefab outer leaf 1 according to the invention with an integrated window frame 16 with window sill 17. The window sill 17 is coupled to the finishing layer 9 and to the outer surface 7 of the basic element 5. The element 18 provides a bridging the prefab element 1 and the inner leaf 2. This element 18 can be a continuous window sill construction 18 which provides a bridging but can also be built up from several parts, for example from a window sill located near the inner leaf and a frame frame located near the outer leaf. The window frame 16 is coupled to this element 18, more in particular to the frame frame.
    In FIG. 3 is a schematic representation of a transition from the prefabricated façade element 1 to a pitched roof structure 19. The prefabricated element 1 is beveled 21 at an upper side 20 where it is coupled to the pitched roof structure 19 at such an angle that the sloping roof structure 19 is flat on it and can be connected to it. The connection is made, for example, by means of troughs 22 passing through the sloping roof construction 19 which engage in material of the prefab element 1. Preferably, the prefab element 1 comprises, near the beveled end 20, an insert which provides sufficient grip to the bolts 22 in order to sturdy construction.
    In the embodiment shown, the sloping roof construction 19 is provided with tile slats 24 for placing roof tiles 25.
    A roof gutter 23 is attached to an insert 26, which is provided on the prefab element 1.
    FIG. 4 finally shows a horizontal section through a facade, wherein an inner sheet 2 and a prefab outer sheet 1 can be clearly distinguished. The prefab outer sheet 1 comprises the basic element 5 with slats 8 provided on the outer surface 7. The finishing layer 9 is attached to the slats 8. A ventilation space 27 is provided between the finishing layer 9 and the base element 5.
    At the location of a recess in the facade construction, for example for a window, a covering structure 18 is provided which covers the cavity 28. An airtight covering of the cavity 28 is hereby obtained around this. The cover structure 18 can serve as a window sill 18, as schematically shown in FIG. 2, although a separate window sill can be provided on this structure 18.
    The base element 5 is formed from a base plate and protruding walls located at peripheral edges of the base plate. An insulating material is provided in the space formed by the bottom and walls. FIG. 5 shows a schematic representation of the installation of insulating material in the space.
    FIG. 5 shows a production hall 29 with a floor 30 and a roof 31 where an element according to the invention can be produced. The hall 29 has a wall 32 against which a counter jig 33 is placed. A base element 34 with a bottom 35 and walls 36 is placed with the sides of the walls 36 remote from the bottom 35 against the counter jig 33. A substantially closed space 37 is hereby formed. The base element 34 is supported at the bottom against a lower support element 38. An upper support element 39 is provided above the base element 34. A box girder 40 is attached to the lower and upper support and presses the base element 34 against the counter jig 33 in a sealing manner.
    A liquid polyurethane supply hose 41 is fed into the base element 34 at the top to feed the polyurethane resin into the space 37 where it will foam to form an insulating foam. A pipework 42 is placed in the space 37 in advance, for example for the purpose of conducting electricity or ventilation. The box girder 40 will be able to remain mounted until the insulating foam has cured. After curing, the base element 34 can be removed from the counter jig 33, whereby the finishing layer can be applied. Confirmation thereof can take place in the position as shown in FIG. 5 or after removal of the basic element 34 from the counter jig 33.
    The invention is not limited to the embodiments described above and shown in the figures. The invention is only limited by the appended claims.
    The invention also extends to any combination of measures described above independently of each other.
