Description
Figure 1 Figure 1 shows a construction element 101. According to this first example, construction element 101 is configured for use as a block within a beam and block floor arrangement. Beam and block floor arrangement 102 comprises a plurality of blocks 101, and a plurality of beams 103. A building wall 104 comprises an outside wall 105 and an inside wall 106. Extending substantially perpendicularly to the inside wall 106 is a supporting wall 107. The beams 103 are located at spaced apart intervals, substantially parallel to the inside wall 106 and each other, and are positioned upon, and supported by, supporting wall 107.
The blocks 101 are located between adjacent beams, to act as an infihl between the beams.
Each beam 103 presents an upper face 108 that forms part of a floor surface, and similarly, each block 101 presents an upper face 109, that forms part of the same floor surface. Once the beams and blocks are laid to form an initial installation, the upper faces 108, 109 of the beams 103 and the blocks 101 respectively 102 present a substrate floor surface.
As will be described in further detail below, construction element 101 is configured to provide thermal insulation and to withstand Construction traffic damage so that construction traffic may be allowed onto the substrate floor surface resultant from the initial installation of the beams and blocks.
Figure 2 Construction element 101 is illustrated in Figure 2 in further detail. The construction element 101 comprises an insulation layer 201 and an outer protective layer 202. The insulation layer 201 typically forms the main body of the construction element 101. The insulation layer 201 comprises an upper face 203 and a lower face 204, with the outer protective layer 203 carried on the upper face 203 of the insulation layer 201. Typically, an outer protective layer is provided on the upper face of the insulation layer only. Alternatively, an outer protective layer may be provided on one or more additional faces of the insulation layer.
The material of the insulation layer 201 is selected to provide suitable characteristics to allow the construction element 101 to function as a block for a beam and block floor arrangement. The material of the insulation layer 201 is also advantageously selected to exhibit a suitable overall heat transfer coefficient (U-value) to allow the construction element 101 to function as thermal insulation. The material of the insulation layer 201 is further selected to be suitably light in weight to allow for convenient manual handling.
The outer protective layer 202 is intended to provide an upper face 109 that forms part of the substrate floor surface of an initial beam and block floor installation, as described with reference to Figure 1. The material of the outer protective layer 202 is selected to provide suitable characteristics to resist damage. The outer protective layer 202 is configured to inhibit construction traffic damage to the insulation layer 201 such that construction operatives may work upon the substrate floor surface immediately after it is formed. The outer protective layer 202 serves to protect the insulation layer 201 from any construction traffic upon the substrate floor surface prior to application of floor completion layers. The construction element 101 is configured to tolerate such events as a person standing or travelling thereupon, a wheelbarrow resting or travelling thereupon, an item being dropped thereon and other general causes of wear and damage to a floor during construction.
Any suitable material or materials may be used in each of the insulation layer and the outer protective layer of a construction element described herein. The insulation layer and the outer protective layer may both comprise a plastics material. The insulation layer may comprise a first polyurethane material having a first density, and the outer protective layer may comprise a second polyurethane material having a second density, with the density of the polyurethane of the outer protective layer typically being greater than the density of the polyurethane of the core layer. The first polyurethane material may be in the form of a low-density rigid foam. The second polyurethane material may be in the form of a high-density flexible layer. The grade of hardness of the outer protective layer may vary between applications.
A construction element intended for use as an infill block in a beam and block floor construction may typically have a width in the range 200mm to 600mm, a length of approximately 1200mm and a depth of approximately 100mm. However, it is to be appreciated that the dimensions may vary between applications. A construction element may comprise an insulation layer having a depth of 95mm and an outer protective layer having a depth of between 1 and 2mm, providing an overall depth of between 96mm and 97mm. It is to be appreciated that the overall dimensions of the construction element, and the weight of the construction element, may vary between applications, The depth of each of layer of the construction element may also vary between applications, and the material of each layer of the construction element may vary between applications. The thermal properties of each layer of the construction element may vary between applications, as may the strength and deformation characteristics of each layer. According to this embodiment, the construction element has a substantially rectangular cross-sectional shape; however, the construction element may have any cross-sectional shape suitable for a particular application. It is to be appreciated that in alternative embodiments, a construction element as described herein may be configured for use in a different type of construction from that described herein.
Figure 3 A method of manufacture 301 of a construction element having an insulation layer and an outer protective layer as described herein is illustrated in Figure 3.
At step 302, an insulation layer is received. The received insulation layer may have been produced by any suitable method. At step 303, the outer protective layer is applied to the upper face of the insulation layer received at step 302. It is to be understood that the received insulation layer may have a covering over each face and that the covering may or may not be removed as applicable prior to step 303. The received insulation layer may be provided with an outer protective layer by any suitable method. In an embodiment, a spray process is utilised to spray the outer protective layer material onto the selected receiving face of the insulation layer. According to an alternative approach, an outer protective layer is formed as an independent component that is subsequently secured to the selected receiving face of the insulation layer by any suitable technique. The insulation layer may be cut to the desired size prior to step 302 or a construction element may be cut to the desired size following step 303, as appropriate. In an example, the selected receiving face of the insulation layer is sprayed with a plastics material that adheres naturally thereto.
Figure 4 Figure 4 shows a construction element 401 having an insulation layer and an outer protective layer as described with reference to the first example and additionally comprising a slip reducing material 402 so as to present a slip-reducing upper surface 403. This feature serves to improve the safety of operatives working on a substrate floor surface comprising upper surface 403. The slip-reducing feature is particularly advantageous in circumstances in which the upper surface 402 of the construction element 401 becomes wet or may become wet. The slip-reducing material may be sand; however the slip-reducing material may comprise any suitable material or combination of materials.
Figure 5 Steps of a first method of manufacture 501 of a construction element having an insulation layer, an outer protective layer and a slip-reducing upper surface as described herein is illustrated in Figure 5. In a similar maimer to the method of manufacture 301 of Figure 3, an insulation layer is received at step 302. At step 502, an outer protective layer comprising slip-reducing material is applied to the selected outer face of the insulation layer received at step 302. Any suitable technique may be employed to provide the received insulation layer with an outer protective layer comprising slip-reducing material. The method of manufacture 501 of Figure 5, in effect, results in a construction element having two layers.
Figure 6 Steps of a second method of manufacture 601 of a construction element having an insulation layer and an outer protective layer and presenting a slip-reducing upper surface as described herein is illustrated in Figure 6. In a similar maimer to the methods of manufacture 301 and 501 of Figures 3 and 5 respectively, an insulation layer is received at step 302. In a similar maimer to the method of manufacture 301 of Figure 3, at step 303, an outer protective layer is applied to the selected outer face of the insulation layer received at step 302. Any suitable technique may be employed to provide the insulation layer with an outer protective layer. At step 602, a slip-reducing layer is applied to the outer protective layer. Any suitable technique may be employed to provide the outer protective layer with a slip-reducing surface.
In an alternative method of manufacture, an outer protective layer carrying a slip-reducing layer may be formed as an independent component that is subsequently secured to the selected receiving face of the insulation layer by any suitable technique. In effect, the method of manufacture 601 of Figure 6, results in a construction element having three layers.
In an example, a face of the insulation layer is sprayed with a plastics material that is sprinkled with sand before the plastic coating sets, so as to provide a rough surface.
Figure 7 A plurality of construction elements 701 according to the present invention are shown as part of a beam and block floor 702 in Figure 7, which also comprises beams 703.
Construction elements 701 may take the form of construction elements 101, having an insulation layer and an outer protective layer, or construction elements 401, additionally presenting a slip-reducing face, or a combination of both. The construction elements present an upper surface 704.
As illustrated in this Figure, operatives 705 and 706 are able to conveniently work directly upon the beams 703 and blocks 701 once installed. As indicated at 707, any gap present between blocks 701 and beams 703 may be filled with any suitable material, to prevent undesired ingress of materials and/or substances such as dirt, dust, liquid or small items therein. The gap infill material may, for example, be a fast-curing adhesive expanding foam such as may be used in another installation process during the build.
From the perspective of operatives 705 and 706, the upper surface 704 of each construction element 701 presents a similar sturdiness to that of a prior art concrete infill block, and provides sufficient support for construction operatives and construction materials and tools. The reduced weight of each construction element 701 compared to a prior art concrete infill block enables a construction element as described herein having an equivalent length of several prior art concrete blocks to be manually handled by an individual. In this way, the construction elements 701 allow for quicker and easier installation of the beam and block floor. In addition, the reduction in weight of the construction elements 701 compared to prior art concrete blocks reduces the risk of injury to an individual in the event that the building slips from grip. A construction element may carry a visual indication, such as may comprise graphics and/or colouration andlor text, to facilitate easy recognition of a side or face having an outer protective layer/slip-reducing surface.
The construction elements 701 also provide improved thermal properties over prior art concrete blocks. In this way, the construction elements 701 provide an environmental benefit by improving the thermal insulation characteristics of the floor of the building. In turn, the construction elements 701 contribute significantly to the overall heat transfer coefficient (U-value) of the completed floor construction. According to an example, a completed floor construction comprising construction elements 701 has a relatively high thermal performance, with a U-value typically between 0.1 W/m2K and 0.2 W/m2K. This provides a flooring solution that beneficially assists attainment of thermal performance targets.
Figure 8 A method 801 of constructing a building in which construction elements according to the present invention are used in a beam and block floor of the building, are shown in Figure 8. Beams are positioned at step 802. At step 803 blocks in the form of construction elements according to the present invention are positioned between the beams laid at step 802, to form an initial beam and block floor installation that provides a resultant substrate floor surface.
Advantageously, the resultant substrate floor surface achieved by performing steps 802 and 803 is fit to receive construction traffic and may therefore be finished at any time.
Thus, at the desired time during the subsequent construction process schedule 804, steps may be performed to complete the beam and block floor. According to an example sequence, the substrate floor surface is cleaned at step 805 in preparation to receive a floor completion layer; a damp-proof layer, such as an impermeable membrane, is installed at step 806; floor insulation is then fitted at step 807, and a screed layer is subsequently applied, at step 808, to complete the floor. Any suitable alternative steps to complete the floor may be performed in any appropriate sequence. It is to be appreciated that the schedule to perform floor completion steps, as indicated at 809, may be initiated at any time after step 803 and hence after any remaining construction stage. For example, application of a screed layer may be performed after the building has been made watertight. In this way, construction elements according to the present invention advantageously provide a degree of flexibility to the overall build schedule and serve to overcome undesired interruptions during building works, since construction traffic may be allowed Onto the substrate floor surface resultant from the initial installation of the beam and block floor.
The present invention thus provides a construction element usable as a block in a beam and block floor of a building that provides considerable advantages for an operative performing the build and that provides considerable advantages for the end user of the building.
