Description

Constructions for buildings
Field of the Invention
The present invention concerns constructions for buildings. In particular, the present invention concerns constructions comprising I-beams and insulating panels between the I-beams. The present invention is particularly, but not exclusively, suitable for domestic buildings, where the I-beams are engineered timber I-beams. The constructions may be floor constructions or roof constructions, or any other suitable type of building construction .
Background of the Invention
Ground floors of domestic buildings conventionally use ground-supported concrete slabs, or a suspended construction using beams, infill and screed. Suspended floor beams are generally formed of concrete, though solid timber joists were a traditional solution in the past.
beams may be standard concrete blocks or
Infill between the expanded shapes .
Domestic upper floors in multi-occupancy dwellings generally constructed using in-situ or precast concrete in a variety of forms .
Engineered timber I-beams have been used for the upper floors in houses, as they have an improved strength-to2 weight ratio compared to solid timber joists. They have also been used in roof constructions. However, they have not been used in combination with an infill system (either concrete block or EPS panels).
The present invention seeks to provide improved constructions for buildings.
Summary of the Invention
In accordance with a first aspect of the invention there is provided a construction for a building comprising:
a plurality of I-beams comprising first and second recesses on opposite sides; and a plurality of insulating panels positioned between adjacent beams of the plurality of I-beams, each insulating panel comprising first and second extended side portions on opposite sides of the insulating panel;
wherein for each insulating panel of the plurality of insulating panels, the first extended side portion of the insulating panel extends into a recess of a first adjacent I-beam, and the second extended side portion of the insulating panel extends into a recess of a second adjacent I-beam, to hold the insulating panel in position between the first and second adjacent I-beams.
In this way, an insulated construction using I-beams is provided. The construction is lightweight compared to constructions using concrete beams or solid timber joists, and can be constructed more easily and quickly. Full-length beams and insulation panels can be supplied and installed as a single section, or indeed an entire construction (e.g. floor or roof) can be constructed off-site and provided as a single item for installation. The construction can have reduced thickness compared to conventional constructions, for example to match the height of the blocks used to build the walls of the building.
The building may be a domestic building.
Advantageously, each insulating panel of the plurality of insulating panels comprises an extended bottom portion that extends beneath an adjacent I-beam. In this way, the extended bottom portions of the insulating panels form an insulating layer that protects the bottoms of the I-beams. Preferably, insulating panel of the plurality of insulating panels comprises a bottom recess in which the extended bottom portion of an adjacent insulating panel is positioned.
Advantageously, each insulating panel of the plurality of insulating panels comprises an extended top portion that extends above an adjacent I-beam. In this way, the extended top portions of the insulating panels form an insulating layer that protects the tops of the I-beams. Preferably, each insulating panel of the plurality of insulating panels comprises a top recess in which the extended top portion of an adjacent insulating panel is positioned.
Advantageously, the construction further comprises a plurality of insulating portions, wherein each insulating portion of the plurality of insulating portions is positioned over a respective I-beam of the plurality of Ibeams.
Preferably, each insulating portion of the plurality of insulating portions comprises an extended fixing portion, and each insulating panel of the plurality of insulating panels comprises a recess into which the extended fixing portion of a respective insulating portion of the plurality of insulating portions is positioned. This allows the insulating portion to be fixed to the insulating panel before the insulating panel is put in position, simplifying the construction process. Alternatively, the insulating panels and insulating portions may be fixed together in other ways, for example glued. Preferably, the extended fixing portion of each insulating portion of the plurality of insulating portions comprises one or more raised portions. This helps the insulating portions and insulating panels stay fixed together. Preferably, the recesses of the insulating panels are correspondingly shaped to receive the raised portion(s), in particular so that the entrances to the recesses are smaller than the height of the extended portion at the raised portion(s), so that the extended portions click into place within the recesses.
Preferably, each insulating panel of the plurality of insulating panels comprises a top recess in which a respective insulating portion of the plurality of insulating portions is positioned.
Advantageously, each insulating panel of the plurality of insulating panels is formed of a first material, and each insulating portion of the plurality of insulating portions is formed of a second material with different properties to the first material. As the insulating panels and insulating portions are formed of different materials having different properties, the materials used can be selected to suit the conditions insulating panels and insulating portions will undergo. In particular, the insulating portions can provide load-bearing support via the I-beams, particularly where the construction is a floor construction, while the insulating panels will not provide any such load-bearing support, and so the materials used can selected appropriately. Advantageously, the first material has a lower thermal conductivity than the second material. Advantageously, wherein the second material has a higher compressive strength than the first material. The second material may be more dense than the first material. Alternatively, the insulating panels and insulating portions may be formed of the same material.
Preferably, the insulating portions of the plurality of insulating portions are formed of an insulating polymer. Preferably, the insulating polymer is expanded polystyrene.
Preferably, the insulating panels of the plurality of insulating panels are formed of an insulating polymer. Preferably, the insulating polymer is expanded polystyrene.
The insulating panels and/or insulating portions may be profile cut from a block of expanded polystyrene or shape moulded. Alternatively, the insulating panels and/or insulating portions may be made of any material from the group of extruded polystyrene, polyurethane or polyisocyanurate. The material may have a thermal conductivity of 0.050W/mK or below. The material may have a thermal conductivity of 0.040W/mK or below. Preferably, the material has a thermal conductivity of 0.036W/mK or below. Advantageously, the material has a thermal conductivity of
0.031W/mK or below. The material may have a thermal conductivity of 0.021W/mK or below. It will be appreciated that other suitable insulating materials could be used.
Preferably, the I-beams are formed of wood. The use of wood results in a reduction in cold bridging between the construction and building walls compared to the use of concrete beams. The wood may be engineered timber. It may be made of laminated layers of wood. It will be appreciated that other suitable materials could be used.
Most advantageously, the I-beams are completely covered and enclosed by the insulating panels (and insulating portions if appropriate) forming insulating layers both above and below the I-beams.
The construction may be a floor construction. The floor construction may be for the ground floor of a building. Alternatively, the construction may be a roof construction. The construction may be any other suitable type of building construction.

Detailed Description
A floor construction in accordance with an embodiment of the invention is now described with reference to Figures 1 and 2. Figure 1 shows a cross-section of the floor construction 1. Figure 2 shows the same floor construction 1 in perspective view.
- 8 The floor construction 1 of Figures 1 and 2 comprises a plurality of engineered timber I-beams 2, each of which comprises a thicker top part and bottom part, connected by a thinner vertical part. Between the I-beams 2 are insulating panels 3, formed of EPS.
At each end of each insulating panel 3 is an extended side portion, shaped to be positioned within the recess of the adjacent I-beam 2 between its top and bottom parts. The extended side portions are sized and shaped to fit exactly within the recesses of the I-beams 2. In certain advantageous embodiments of the invention the extended side portions are shaped to be very slightly larger than the recesses, so as to provide a friction fit to keep the insulating panels in place once the extended side portions have been positioned within the recesses.
The tops of the insulating panels 3 are at the same level as the tops of the I-beams 2. In other words, the part of the insulating panels 3 above the extended side portions is the same height as the top part of the I-beams 2 .
The bottom of the insulating panels 3 is below the level of the bottom of the I-beams 2. Further, each insulating panel 3 has on its bottom left side an extended bottom portion 3a that extends beneath the bottom part of the adjacent I-beam 2 on its left, and beyond so that the extended bottom portion 3a also extends beneath a part of the adjacent insulating panel 3 on its left. Each insulating panel 3 further has a bottom recess on its bottom right side, into which the extended bottom portion 3a of the insulating panel 3 to its right fits.
As can be seen in Figure 1 (not shown in Figure 2), a covering layer of plywood decking 5 is positioned on top of the I-beams 2 and insulating panels 3. The plywood decking 5 is fixed using nails to the top parts of the I-beams 2. However, it will be appreciated that in other embodiments the plywood decking 5 may be fixed above the I-beams 2 and insulating panels 3 by other means, for example by gluing to the I-beams 2 and/or insulating panels 3, or may simply be floating on the insulating panels 3. It will further be appreciated that other types of covering layer may alternatively or additionally be used.
As can be seen, the I-beams 2 and insulating panels 3 together form a single continuously solid construction, with no gaps through or within the construction. In particular, the extended bottom portions 3a of the insulating panels 3 mean that the insulating panels 3 together form an insulating layer completely covering and enclosing the bottoms of the I-beams 2.
In an embodiment of the invention, the floor construction 1 is constructed in place at the building within which it is used. A first I-beam 2 is fixed in the desired position, and a first insulating panel 3 is then positioned next to the first I-beam 2 so that the extended side portion on its side adjacent to the first I-beam 2 is within the adjacent recess of the first I-beam 2. A second I-beam 2 is then positioned next to the first insulating panel 3 so that the extended side portion on the other side of the first insulating panel 3 is within the adjacent recess of the second I-beam 2. A second insulating panel 3 is then positioned next to the second I-beam 2, and I-beams 2 and insulating panels 2 are alternately positioned until the floor construction is complete.
In a particularly advantageous alternative embodiment of the invention, the floor construction 1 is constructed off-site, and supplied as a single pre-constructed piece for installation in a building.
A floor construction in accordance with another embodiment of the invention is now described with reference to Figure 3. The floor construction 11 of Figure 3 again comprises I-beams 2 and a covering layer of plywood decking
5. Between the I-beams 2 are again positioned insulating panels formed of EPS, with extended side portions on each side of the insulating panels which fit into the recesses of the I-beams 2.
However, the insulating panels 11 of the present embodiment do not have extended bottom portions that extend beneath the bottoms of the I-beams 2, but rather the bottoms of the insulating panels 11 are at the same level as the bottoms of the I-beams 2. Instead, in the present embodiment each insulating panel 11 has on its top left side an extended top portion 11a that extends above the top part of the adjacent I-beam 2 on its left and beyond so that the extended top portion 11a also extends above the adjacent insulating panel 11 on its left. Each insulating panel 11 further has a top recess on its top right side, into which the extended top portion 11a of the insulating panel 11 to its right fits.
Thus, in the present embodiment the extended top portions 11a of the insulating panels 11 mean that the insulating panels 11 together form an insulating layer completely covering and enclosing the tops of the I-beams 2. The covering layer of plywood decking 5 is then fixed to the top surface of the insulating layer formed by the insulating panels 11.
A floor construction in accordance with another embodiment of the invention is now described with reference to Figure 4. The floor construction 14 of Figure 4 again comprises I-beams 2, a covering layer of plywood decking 5, and insulating panels formed of EPS between the I-beams 2 with extended portions on each side which fit into the recesses of the I-beams 2.
In the present embodiment, the insulating panels 15 have both extended portions that extend both above the tops and beneath the bottoms of the I-beams 2. In particular, each insulating panel 15 has on its bottom left side an extended bottom portion 15a that extends beneath the bottom part of the adjacent I-beam 2 on its left and beyond, and on its top left side an extended top portion 15b that extends above the top part of the adjacent I-beam 2 on its left and beyond. Each insulating panel 15 further has a bottom recess on its bottom right side into which the extended bottom portion 15a of the insulating panel 15 to its right fits, and a top recess on its top right side into which the extended top portion 15b of the insulating panel 15 to its right fits .
Thus, in the present embodiment the extended bottom portions 15a on the bottoms of the insulating panels 15 and the extended top portions 15b on the tops of the insulating panels 15 form insulating layers completely covering and enclosing the entirety of the I-beams 2.
A floor construction in accordance with another embodiment of the invention is now described with reference to Figure 5. The floor construction 20 of Figure 5 again comprises I-beams 2 and a covering layer of plywood decking
5. In the present embodiment there is in addition a layer of underfloor heating 6 beneath the plywood decking 5. There are again insulating panels formed of EPS between the I-beams 2 with extended portions on each side which fit into the recesses of the I-beams 2.
In the present embodiment, each of the insulating panels 21 has on its bottom left side an extended bottom portion 21a that extends beneath the bottom part of the adjacent I-beam 2 on its left and beyond, and a bottom recess on its bottom right side into which the extended portion 21a of the insulating panel 21 to its right fits.
Further, each of the insulating panels 21 has on its top left side a recess formed between the leftmost portion 21b of the top part of the insulating panel 21 and the main part of the insulating panel 21. For each insulating panel 21, a corresponding insulating portion 22 has a corresponding rightmost portion 22a that is positioned in the recess of the insulating panel 21. The insulating portion 22 is formed of a different material to the insulating panel 21, as discussed in more detail below.
However, in alternative embodiments, the insulating portion 22 is formed of the same material as the insulating panel
21.
The leftmost portion 21b of the insulating panel 21 and the rightmost portion 22a of the insulation portion 22 are both shaped to be thicker towards their outermost edge. In this way, once the rightmost portion 22a of the insulation portion 22 has been positioned within the recess of the insulating portion 21, it is held in place by a friction fit. This makes the insulating panel 21 and insulating portion 22 easier to install, without any glue or other type of fixing being required.
The insulating portion 22 is sized so that the upper surface of the insulating portion 22 is at the same level as the upper surface of the insulating panel 21, so that the upper surface of the first insulating portion 1 and the upper surface of the second insulating portion 5 together provide a single continuous flat surface. The insulating portion 22 extends above the top part of the adjacent I-beam 2 on its left and beyond, into a top recess on the top right side of the right adjacent insulating panel 21.
Thus, in the present embodiment the extended portions 21a on the bottom of the insulating panels 21 form an insulating layer completely covering and enclosing the bottom of the I-beams 2. Further, the insulating portions 22 form with the insulating panels 21 an insulating layer completely covering and enclosing the top of the I-beams 2. In this way, the I-beams 2 are entirely covered and enclosed.
As mentioned above, the insulating panels 21 and insulating portions 22 are formed of different materials. In particular, the insulating panels 21 are formed of a low density insulating material with low thermal conductivity. The insulating portions 22 are formed of a higher density insulating material with higher thermal conductivity than the insulating panels 21, but also a higher compressive strength. In this way, the low thermal conductivity of the material of the insulating panels 21 positioned between the I-beams 2 provides a high level of insulation, while the high compressive strength of the material of the insulating portions 22 positioned over the beams provides good loadbearing properties. However, as the insulating panel 21 and insulating panel 22 can be provided as connected parts of a single item, construction using the insulating panels 21 and insulation portions 22 is simple. Further, as each insulating portion 22 sits in the recess of an adjacent insulating panel 21 they are kept in place, making the floor construction 20 secure and easy to construct.
A roof construction in accordance with another embodiment of the invention is now described with reference to Figure 6. The roof construction 50 is a cold roof construction, i.e. one in which there is a layer of colder air between the insulation in the roof construction and the upper outer layer of the roof construction 50.
The roof construction 50 of Figure 6 comprises I-beams 40 and a covering layer of plywood decking 41 positioned on top of the I-beams 40. The roof construction also has a covering layer of plasterboard 42 positioned underneath the I-beams 40, as described in more detail below.
Similarly to the floor construction shown in Figure 1, in the present embodiment there are again insulating panels 51 formed of EPS between the I-beams 40, which have extended portions on each side which fit into the recesses of the Ibeams 40. However, in the present embodiment the top of the insulating panels 51 is at the same level as the top of the recess of the I-beams 40, and so also at the same level as the top of the extended portions on each side of the I-beams 40. As such, there is a void 52 containing air between the tops of the insulating panels 51 and the lower surface of the layer of plywood decking 41.
In the present embodiment, each of the insulating panels 51 has on its bottom right side an extended bottom portion 51a that extends beneath the bottom part of the adjacent I-beam 40 on its right and beyond, and a bottom recess on its bottom left side into which the extended portion 51a of the insulating panel 51 to its left fits.
Thus, in the present embodiment the extended portions 51a on the bottom of the insulating panels 51 form an insulating layer completely covering and enclosing the bottom of the I-beams 40. The plasterboard layer 42 is then attached to this insulating layer.
A roof construction in accordance with another embodiment of the invention is now described with reference to Figure 7. The roof construction 60 is a warm roof construction, i.e. one in which there is no layer of colder air between the insulation in the roof construction and the upper outer layer of the roof construction 60.
The roof construction 60 of Figure 7 again comprises Ibeams 40, a covering layer of plywood decking 41 positioned above the I-beams 40, and a covering layer of plasterboard 42 positioned underneath the I-beams 40.
Similarly to the floor construction shown in Figure 3, in the present embodiment there are insulating panels 61 formed of EPS between the I-beams 40, which have extended portions on each side which fit into the recesses of the Ibeams 40. Each of the insulating panels 61 has on its top left side an extended top portion 61a that extends above the upper part of the adjacent I-beam 40 on its left and beyond, and a top recess on its top right side into which the extended portion 61a of the insulating panel 61 to its right fits. Thus, in the present embodiment the extended portions 61a on the top of the insulating panels 61 form an insulating layer completely covering and enclosing the top of the I-beams 40. The covering layer of plywood decking 41 is then attached to this insulating layer. The plasterboard layer 42 is attached to the bottoms of the I-beams 40.
A roof construction in accordance with another embodiment of the invention is now described with reference to Figure 8. The roof construction 70 is again a warm roof construction .
The roof construction 70 of Figure 8 again comprises Ibeams 40, a covering layer of plywood decking 41 positioned above the I-beams 40, and a covering layer of plasterboard 42 positioned underneath the I-beams 40.
Similarly to the floor construction shown in Figure 4, in the present embodiment there are insulating panels 71 formed of EPS between the I-beams 40, which have extended portions on each side which fit into the recesses of the Ibeams 40. Each of the insulating panels 71 has on its bottom left side an extended top portion 71a that extends below the lower part of the adjacent I-beam 40 on its left and beyond, and a bottom recess on its bottom right side into which the extended portion 71a of the insulating panel 71 to its right fits. In addition, each of the insulating panels 71 has on its top left side an extended top portion 71b that extends above the upper part of the adjacent I-beam 40 on its left and beyond, and a top recess on its top right side into which the extended portion 71a of the insulating panel 71 to its right fits. Thus, in the present embodiment the extended portions 71a on the bottom of the insulating panels 71 form an insulating layer completely covering and enclosing the bottom of the I-beams 40, and the extended portions 71b on the top of the insulating panels 71 form an insulating layer completely covering and enclosing the top of the I-beams 40, so that the I-beams 40 are completely enclosed and protected by the insulating panels 71. The covering layer of plywood decking 41 is then attached to the upper insulating layer, and the plasterboard layer 42 is attached to the lower insulating layer.
It will be appreciated that in other embodiments where there is a roof construction, there may be insulating panels and connected insulation portions similar to those shown in Figure 5, which may be formed of different materials.
While the present invention has been described and illustrated with reference to particular embodiments, it will be appreciated by those of ordinary skill in the art that the invention lends itself to many different variations not specifically illustrated herein. The skilled person will in particular appreciate that the insulating panels could be shaped in various alternative ways while still being in accordance with the invention.
