Examples of the present invention will now be described in more detail, by way of example only, and with reference to the accompanying drawings, in which: Fig. 1 is a perspective view of an embodiment of a stairway according to the invention; Fig. 2 is a section through the stairway of Fig 1, along the line 2-2; Fig. 3 is a perspective view of the cladding of the stairway of Fig. 1, during the manufacturing process; and Figs. 4 to 7 correspond with Fig. 3, showing various stages in the method of manufacture of the stairway of Fig. 1.
Figs. 1 and 2 illustrate a stairway 10. The stairway 10 includes a set body 12 of settable material. Cladding 14 is provided over at least part of the surface of the body 12, as will be described. This forms a stairway 10 of cladding 14 supported by the set body 12.
In this example, the body 12 is formed of a settable material such as a cementitious material. This may be a cement mix, a plaster mix or a combined mix of plaster and cement. The use of settable material for forming the body 12 allows other material to be incorporated into the stairway 10. For example, thermal insulating material may be incorporated in the body 12, in the form of beads or other small particles. This material may be a polymer material. Polystyrene is an example of an insulating material which may be incorporated in bead form in a cement mix, forming material sometimes called 1 5 "polyconcrete". Thermal insulating materials, such as polystyrene, may also provide enhanced insulation of other parameters, such as sound and/or fire.
The body 12 also incorporates reinforcement 16. The reinforcement 16 is illustrated in this example as a square mesh of elongate reinforcing members, which may be metal. Other forms of metal reinforcement and other mesh forms could be used. Alternatively, the reinforcement 16 could be in the form of fibres, such as synthetic fibres, which may be in the form of a woven or non-woven mat of reinforcing fibres.
The body 12 of set material, in combination with the reinforcement 16, forms a structure which is sufficiently strong to provide the structural strength of the stairway 10.
The upper face of the stairway 10 has a series of steps 20 separated by risers 22. In this example, the cladding 14 dads the steps 20 and risers 22, thus forming the steps and risers as seen by a user. Thus, the cladding 14 covers substantially the whole exposed face of the steps 20 and risers 22.
In other examples, the body 12 may be only partially clad In this example, the cladding 14 is in the form of sheets of material, such as wood. The cladding 14 is provided with features which provide, in use, mechanical engagement between the cladding 14 and the body 12. In this example, the features are recesses 24 formed in the back face of the cladding 14. The recesses 24 may be grooves, each receiving a small ridge 26 of material of the body 12, to provide the mechanical engagement or keying. In this example, recesses 24 are formed in the cladding 14. Other possibilities include projections formed on the cladding 14, received in recesses in the body 12. The security of fixing between the cladding 14 and the body 12 may be further enhanced by providing bonding material at the 1 5 abutting surfaces of the body 12 and cladding 14, as will be described.
An example of a method for manufacturing the stairway 10 will now be described with reference to the remaining drawings.
Fig. 3 shows the cladding 14, formed as the first step of the method. In Fig. 3, the cladding 14 is inverted Accordingly, the surfaces visible in Fig. 3 are the rear faces of the cladding, which include the grooves 24. Chocks 28 may be used to maintain the form of the cladding 14 at this stage of the method Timber cheeks 30 may be used at both sides of the cladding 14, to form finishing trim in the stairway 10.
Accordingly, it can be seen from Fig. 3 that the upturned cladding 14 forms a shallow trough with a stepped floor and side walls provided by the cheeks 30. Thus, the cladding 14 is in the form of a mould which, when inverted as shown in Fig. 3, can receive settable material for forming the set body 12, prior to setting. Fig. 4 illustrates the step of introducing the settable material into the mould provided by the cladding 14. Prior to the introduction of settable material 32, the back surfaces of the cladding 14 may be prepared by coating with a bonding agent, such as a styrene-butadiene co-polymer latex, common known as SBR and available from Degussa Construction Chemicals (UK) of Manchester, United Kingdom, under the name FEBOND SBR. Prior to setting, the material 32 will flow across the back faces of the cladding 14, constrained by the cheeks 30, and into the grooves 24. This flow may be encouraged, for example by placing the cladding mould on a vibrating table. When the cladding mould 14 is partially filled, the reinforcement 16 is introduced, as illustrated in Fig 5. Again, this example illustrates a reinforcement 16 in the form of a square mesh of elongate metal reinforcing members, but other forms of reinforcement could be used. Introduction of settable material 32 then continues, covering the reinforcement 16. The final level of the settable material 32 is a little below the height of the cheeks 30, leaving a short lip of the cheeks 30, proud above the material 32. The purpose of these lips will become apparent below.
While the material 32 is still unset, score marks 34 are provided across its upper face. The settable material 32 is then left in the cladding mould 14 until set. Typically, this may take about twenty four hours, but this time will depend on the composition of the material 32, ambient conditions and other factors.
The purpose of the scores 34 is to prepare the body 12 for plastering.
In this example, manufacturing of the stairway 10 is concluded by forming a plaster layer 36. Alternatively, the stairway 10 could be left unplastered, for subsequent cosmetic finishing.
Once the material 32 is fully set, and the plaster layer 36 is set, if present, the construction can be inverted to the orientation illustrated in Fig. 1.
This results in the cladding layer 14 being above the body 12, with the plaster layer on the downward-facing face 38 (indicated by an arrow in Fig. 1).
Accordingly, when the stairway 10 is installed in a building, a user will have the impression of climbing a staircase made entirely of the cladding material. In this example, the impression would be of climbing a wooden staircase From below, if the lower surface is exposed in the building, a neat finish is provided by the plaster layer 36, which may be decorated as soon as the stairway 10 is installed. However, the structural strength of the stairway is provided by the body 12 and reinforcement 16. In addition, the body 12 provides enhanced thermal, acoustic and fire retardant properties in comparison with a conventional, wholly wooden stairway. These effects are expected to be particularly demonstrated if the body 12 incorporates polystyrene or other insulating material, as described above.
It is envisaged that the stairway is formed at a first site, such as a 1 5 factory, to ensure consistent quality of manufacture. The manufactured stairway 10 can then be transported to a second site for installation in a building.
The stairway 10 may be extended at the top or bottom to form an area of floor or landing formed in the same manner described, that is by extending the cladding mould 14 and providing additional settable material to form a set body behind the cladding of the floor or landing.
Many variations and modifications can be made to the apparatus and method described above, without departing from the scope of the invention.
In particular, a wide range of dimensions and relative dimensions, and alternative materials could be used.
Whilst endeavouring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon.
