Description

Building blocks, and walls comprising building blocks
Field of the Invention
The present invention concerns building blocks, and walls comprising building blocks. In particular, the invention concerns building blocks comprising insulating inserts .
Background of the Invention
It is often desirable for concrete building blocks to have high thermal performance. It is known to use specialist aggregates to produce such building blocks, in particular in order to allow the building blocks to be formed of low-density concrete. However, such specialist aggregates can be expensive and/or difficult to obtain. One reason for this is that a common source of specialist aggregates has been coal-burning power stations, which are now less commonly in operation.
It is known to use expanded polystyrene (EPS) when in the construction of building blocks. However, such known building blocks are usually complicated in construction. It would be desirable to provide building blocks with high thermal performance that are of simple construction, so that they can easily be used in construction.
While GB2225977A (Frances Kenneth), published 20 June 1990, discloses a building block with an expanded polystyrene core, it would be desirable to provide improved building blocks. It would further be desirable to provide building blocks that allow insulated walls to be easily constructed.
With this in mind, the present invention seeks to provide improved building blocks, and improved walls comprising building blocks.
Summary of the Invention
In accordance with a first aspect of the invention there is provided a building block for a wall, comprising:
a body formed of concrete;
one or more insulating inserts arranged within the concrete body; and an insulating panel arranged on a face of the concrete body.
By having one or more insulating inserts within the concrete body of the building block, a building block that is lighter and has higher thermal performance is provided, without the use of specialist aggregates being required. In addition, the insulating panel on a face of the concrete body provides additional insulation when the building blocks are used in a construction such as a wall, as by arranging the building blocks so that each has the insulating panel on the same side, the insulating panels together form an insulating layer on the side of the wall. Further, the insulating layer is provided using only the building blocks, with no additional building components (e.g. separate insulating panels) or construction thereof being reguired.
Preferably, the face of the concrete body is completely covered by the insulating panel.
Advantageously, the one or more insulating inserts are connected to the insulating panel. This allows the insulation parts of the building block to be provided as a single contiguous body of insulating material. This helps keep the insulating panel securely in place with respect to the concrete body, without any additional fixing (e.g. gluing the insulating panel to the face of the concrete body) being required. Further, it advantageously allows simple construction of the building blocks, by first providing the body of insulating material which is placed into a mould. The concrete is then poured into the mould over the body of insulating material, which sets to form the finished building block.
Advantageously, at least one edge of the insulating panel extends beyond the corresponding edge of the concrete body. When the building blocks are used in a construction with mortar or the like joining the building blocks, there will be a small gap between the concrete body of each building block. By having the insulating panel extend beyond the concrete body, insulating layer provided by the insulating panels of the building blocks is able to cover the gaps between the concrete bodies of the building blocks.
Further advantageously, the edge of the insulating panel opposite the at least one edge is recessed inside the corresponding opposite edge of the concrete body. This helps ensure the insulating panels cover the gaps between the concrete bodies of the building blocks, as the extended edges of the insulating panels can extend into the recesses.
Further advantageously again, two edges of the insulating panel extend beyond the corresponding edges of concrete body. This allows gaps above and below, and also to either side, of the concrete bodies of the building blocks to be covered by the insulating panels.
Advantageously, the insulating panel comprises: a first portion adjacent to the concrete body, wherein the edges of the first portion do not extend beyond the edges of the concrete body; and a second portion, wherein at least one edge of the second portion extends beyond the corresponding edge of concrete body. This ensures even better cover by the insulating panels with no cold bridges (i.e. gaps in insulation where heat can be lost), as the insulating panel has a stepped configuration meaning that the edges where the first portions meet are offset from the edges where the second portions meet. In this way, the edges where the first portions meet have in front of them an area of second portion without any gap (even if there is a small gap between the second portions themselves). Similarly, the edges where the where the second portions meet have behind them an area of first portion without any gap (again even if there is a small gap between the first portions themselves).
Advantageously, the face of the second portion is longer on at least one axis than the face of the first portion. More advantageously, the face of the second portion is longer on both axes than the face of the first portion. This means that when the edges of the second portions meet, there is still a small gap between the edges of the first portions. This provides a space into which mortar or the like can squeeze when the building blocks are being used to construct a wall. This means that the presence of excess mortar does not prevent the edges of the second portions being able to meet, even though the present of the second portions themselves mean any excess mortar cannot be removed during construction of the wall.
Advantageously, the body is formed of high-density concrete. The use of the insulating inserts allows highdensity concrete to be used without the building block having too poor a thermal performance, and also without the building block being excessively heavy. The high-density concrete provides increased strength, which is particularly advantageous as the concrete is only present in areas of the building block around the insulating inserts. High-density concrete is also less expensive than low-density concrete formed using specialist aggregates. Concrete with a density of 2400kg/m3 may be used. Concrete with a density of above 2400kg/m3 may be used. Concrete with a density of 2000kg/m3 , or of above 2000kg/m3 may be used. Particularly (but not necessarily) where concrete of a density of below 2400kg/m3 is used, the concrete may comprise aggregates, for example natural crushed stone and/or sand aggregates.
Preferably, the one or more insulating inserts and/or the insulating panel are formed of an insulating polymer. More preferably, the insulating polymer is expanded polystyrene. Alternatively, the one or more insulating inserts and/or the insulating panel may be formed 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.
A surface of the one or more insulating inserts may be exposed on at least one face of the building block.
The one or more insulating inserts may be triangular in cross-section. However, it will be appreciated that other shapes and configurations for the insulating inserts could be used. Insulating inserts that are rectangular in crosssection may be used, for example, particularly as this would allow a block to be split into narrower sections to match a desired final length of a wall.
Preferably, the concrete body completely covers the one or more insulating inserts on at least first and second opposite sides. More preferably, concrete body completely covers the one or more insulating inserts on a further third and fourth opposite sides. This allows the concrete body to provide strength for the building block, and to protect the insulating inserts .
In accordance with a second aspect of the invention there is provided a building block for a wall, comprising:
a body formed of concrete; and one or more insulating inserts arranged within the concrete body;
wherein the body is formed of high-density concrete.
The use of the insulating inserts allows high-density concrete to be used without the building block having too poor a thermal performance, and also without the building block being excessively heavy. The high-density concrete provides increased strength, which is particularly advantageous as the concrete is only present in areas of the building block around the insulating inserts. High-density concrete is also less expensive than low-density concrete formed using specialist aggregates.
Preferably, the one or more insulating inserts are formed of an insulating polymer. More preferably, the insulating polymer is expanded polystyrene.
A surface of the one or more insulating inserts may be exposed on at least one face of the building block.
The one or more insulating inserts may be triangular in cross-section .
Preferably, the concrete body completely covers the one or more insulating inserts on at least first and second opposite sides. More preferably, concrete body completely covers the one or more insulating inserts on a further third and fourth opposite sides.
In accordance with a third aspect of the invention there is provided a wall comprising a plurality of building blocks as described above.
Preferably, the wall further comprises a joining layer of mortar between the building blocks of the plurality of building blocks.
Advantageously, the building blocks comprise an insulating panel as described above, and the insulating
- 8 panels of adjacent building blocks of the plurality of building blocks are in contact. This provides a continuous layer of insulation over the concrete bodies of the building blocks .
It will of course be appreciated that features described in relation to one aspect of the present invention may be incorporated into other aspects of the present invention .

Detailed Description
A building block in accordance with an embodiment of the invention is now described with reference to Figures la to 2b .
Figures la and 2a are front and back views of an insulating insert 1 for the building block 11. The insulating insert 1 is formed of expanded polystyrene (EPS). Figures 2a and 2b show the building block 11, which comprises a concrete body 10 in which the insulating insert 1 is incorporated.
The concrete body 10 is formed from standard- or highdensity concrete. Standard-density structural concrete has a density of 2400kg/m3. (Concrete with a density of 1750kg/m3 is commonly referred to as medium-density.) Thus, in embodiments of the invention the concrete body 10 is formed from concrete with a density of 2400kg/m3. In other embodiments, concrete with a density above 2400kg/m3 is used. In other embodiments of the invention, concrete with a density of 2000kg/m3 or above all using natural crushed stone and sand aggregates is used.
The insulating insert 1 comprises a front portion 5.
As can be seen from Figures lb and 2b, the front portion 5 is a thin cuboid aligned with and of the same height and width as the concrete body 10 of the building block 1, so that it forms a front to the concrete body 10. Thus, from the front of the building block 11, the concrete body 10 is completely hidden by the front portion 5 of the insulating insert 1.
The insulating insert 1 further comprises four insert portions 2, which are triangular in cross-section. The four insert portions 2 extend from the front portion 5. When the insulating insert 1 is incorporated in the concrete body 10, the insert portions 2 extend completely through from the front to the back of the concrete body 10, so that, as shown in Figure lb, the backs of the insert portions 2 are visible from the back of the building block 11.
The insulating insert 1 further comprises an offset face portion 8, positioned on the other side of the front portion 5 from the concrete body 10. Thus, together the front portion 5 and offset face portion 8 form an insulating panel on the front face of the concrete body 10.
Similarly to the front portion 5, the offset face portion 8 is a thin cuboid of similar height and width as the concrete body 10 of the building block 11. The offset face portion 8 is however thicker than the front portion 5.
So, where for example the building block 11 has an overall
thickness of 150mm, the offset face portion 8 may have a
thickness of 40mm, so that the concrete body 10 and front
portion 5 together have a thickness of 110mm, making them
easy to pick up by hand. (110mm is a common thickness for building blocks for this reason.) The front portion 5 itself may have a thickness of 5mm, so that the concrete body 10 has a thickness of 105mm.
The offset face portion 8 is in addition offset from the front portion 5 and concrete body 10. In particular, as can be seen from Figures lb and 2b, the offset face portion 8 is offset down and to the left of the front portion 5 and concrete body 10, when looking at the face of the building block 11 on which the front portion 5 and offset face portion 8 are located. In the example above in which the building block 11 has an overall thickness of 150mm and the offset face portion 8 has a thickness of 40mm, the offset face portion 8 may be offset by 15mm, for example.
Finally, the offset face portion 8 is not exactly the same height and width as the front portion 5 and concrete body 10. Rather, the offset face portion 8 is slightly taller and wider than the front portion 5 and concrete body
10. In the example above in which the building block 11 has an overall thickness of 150mm and the offset face portion 8 has a thickness of 40mm, the offset face portion 8 may be 10mm taller and 10mm wider than the front portion 5 and concrete body 10, for example.
A portion of a wall in accordance with an embodiment of the invention is now described with reference to Figures 3a to 3c. Figure 3a is a front view of the portion of the wall, Figure 3b is a cross-sectional view of the portion of wall of Figure 3a though the line A-A, and Figure 3c is a top view of the portion of the wall.
The wall 100 comprises two layers 120 and 121. A first layer 120 of the wall 100 is formed of bricks 102, and provides the exterior of the wall. The bricks 102 are joined by a layer of mortar 101 between the bricks 102. A second layer 121 of the wall 100 is formed of the building blocks 11, as described in more detail below. Between the first layer 120 and second layer 121 is an air gap 104.
As can be seen in particular from Figures 3b and 3c, the second layer 121 comprises on the side opposite the air gap 104 and first layer 120 a plasterboard layer 103. This plasterboard layer 104 will in practice form the interior of the building/room formed by the wall 100.
Similarly to the bricks 102 of the first layer 120, the building blocks 11 of the second layer 121 are joined by a layer of mortar 101 between the building blocks 11. The front portions 5 and offset face portions 8 of the building blocks 11 face the air gap 104 of the wall 100, in other words on the other side to the plasterboard layer 103. As can be seen, the edges of the offset face portions 8 of each building block 11 touch the adjacent edges of the offset face portions 8 of the adjacent building blocks 11, so that the offset face portions together form a continuous layer of insulation facing the air gap 104.
It can further be seen from Figure 3b that, as the offset face portions 8 are taller than the front portions 5, there is a small space between adjacent front portions 5 when their offset face portions 8 are touching. This provides a space into which any excess mortar can squeeze as the building blocks 11 are put in place, so that excess mortar does not prevent the building blocks 11 being properly located. This allows the continuous layer of insulation provided by the offset face portions 8 to be formed, despite the fact that the presence of the offset face portions 8 means that any excess mortar cannot be removed.
In this way, the building blocks 11 can easily be used to build a wall with an insulating layer. Further, the insulating inserts 2 of the building blocks 11 mean that they are lightweight and easy to handle, without specialist aggregates being required for their manufacture. In addition, the use of high-density concrete to form the concrete bodies 10 of the building blocks 11 means that the building blocks 11 have good structural strength.
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 concrete bodies, insulating inserts and insulating panels (if present) of the building blocks could be configured and dimensioned in various different ways and still be in accordance with the invention .
