Definitions

• This invention relates to a brick, or protector block for pipes.
• Bricks (or 'blocks') are an important element in the construction of buildings throughout the world. Bricks are typically made from a clay-based mixture (comprising silica, alumina, lime, and other materials), or from concrete in the case of breeze-blocks. They allow for a great deal of flexibility in their application due to the number of different shapes and sizes of brick that are commonly available, and their modular nature. Bricks are typically laid by hand, and adhered to other bricks with mortar.
• Pipes can be provided on the exterior and/or interior of buildings, fixed to the exterior and/or interior surface(s) of the walls, for example.
• pipes it is advantageous for pipes to be embedded within a wall itself, for practical and/or aesthetic purposes, for example.
• One method of achieving this is to leave a gap in the brickwork; pipes are then laid in the gap, and the space surrounding the pipes in the gap is filled with concrete.
• the concrete is typically retained in the gap by wooden boards which are removed once the concrete has set. This process takes time and presents other disadvantages such as potentially distorting the shape of the walls.
• a 'false' inner wall e.g. made out of plaster
• Providing a false inner wall in this way is often undesirable.
• the present invention provides a brick for protecting pipes and embedding pipes in walls which alleviates some of the problems associated with the conventional means and/or methods for embedding pipes in walls. Aspects and embodiments of the current invention are set out in the appended claims. These and other aspects of the invention are also described herein.
• a brick suitable for protecting a pipe, in the shape of a 'IT in the Latin alphabet.
• the brick may be made from a clay-based material.
• the brick may be manufactured by extrusion.
• the brick may have a compressive strength of at least 10 N/mm 2 and ideally up to 20 N/mm 2
• the brick may be frangible upon application of a force exceeding 20 N/mm 2 .
• the U shape of the brick may be formed by three walls.
• a first wall and a second wall may oppose one another and be substantially parallel.
• a third wall may be substantially perpendicular to the first and second opposing walls, and connect the first and second opposing walls thereby to form a U shape. At least one of said walls may comprise a plurality of cavities. The cavities may extend longitudinally within said walls.
• the brick may comprise a plurality of channels on an outer surface of at least one of said walls.
• the outer channels may extend longitudinally on the outer surface of the at least one of said walls.
• the brick may further comprise a fourth wall suitable to be removed prior to installation.
• the fourth wall may be thinner than said other walls.
• the fourth wall may be more frangible than said other walls.
• a method of accommodating pipes within a wall comprising: constructing a wall and leaving a gap for a pipe to be placed within said wall; and placing at least one brick in the shape of a 'IT in Latin in said gap.
• the method may further comprise placing pipes to be accommodated in the wall in said gap prior to placing said bricks in said gap.
• the method may further comprise placing pipes to be accommodated in the wall in said gap after placing said bricks in said gap.
• the invention relates to a brick, or protector block for pipes, manufactured from any material such as clay, cement, gypsum, plastic, etc., and is formed in the form of U in Latin.
• the brick may be in the form of the letter (U) to facilitate its installation during the construction of walls and used in the process of protection of pipes and extensions and is installed around tubes to protect them without the need for the traditional method of plumbing, electricity, Internet, telephone, air conditioners and other extensions.
• the invention displaces the use of wood, carpentry and concrete in the extensions which have to be sprinkled with water and wait to dry for several days. The wood may subsequently decompose. labour costs are therefore reduced as processing, installation and dismantling of wood blocks is not necessary.
• the brick may have a fourth side to protect the product which is easily removed when installing the product, so as to provide an opening for the product to fit around pipes. Openings may be provide in the brick to allow the existence of spaces within the brick itself and these openings provide the product insulation of sound and heat, which provides effective protection of the pipes.
• the spaces in the product may facilitate the process of cracking the product during maintenance also and there will be a lot of cracking and internal extensions are protected inside the product if there is a stretch or shrink during maintenance.
• the term 'U-shaped' relates to the shape of the letter 'U' in the Latin alphabet. Such a shape comprises opposing first and second line segments that are substantially parallel, and a third line segment connecting neighbouring ends of the first and second line segments, the third line segment being substantially perpendicular to the opposing first and second line segments.
• the term 'U-shaped' can also refer to a three-dimensional shape having a cross- section that is substantially U-shaped.
• Figure 1 shows computer-aided design (CAD) drawings of a first embodiment of the invention
• Figure 2 shows CAD drawings of a second embodiment of the invention
• FIG. 3 shows photographs of the second embodiment of the invention
• Figure 4 shows CAD drawings of a third embodiment of the invention
• Figure 5 shows examples of the invention, in use.
• the present invention provides a brick for protecting pipes and embedding pipes in walls.
• the brick affords increased ease and speed of embedding pipes in walls compared with the current art solutions.
• the brick of the current invention is designed to accommodate a pipe or several pipes, and can be used in the construction of a wall like an ordinary brick. This obviates the need for leaving a gap in the brickwork to accommodate pipes and filling the gap with concrete which would have to be left to set for several hours.
• the current invention affords improved ease and speed of embedding pipes in walls.
• the lack of a concrete-filled gap in the wall also affords improved structural strength.
• the bricks of the present invention accommodate and surround the pipes in the wall, creating a barrier between them and the surrounding environment. This means that the pipes are less likely to become damaged after being put in place - both while the remainder of the wall is completed, and when the pipes are in use after the construction of the building is completed. Additionally, the bricks are designed to be heat insulating and thus protect the pipes from temperature variations. This heat insulation reduces the amount of expansion and contraction that the pipes in the wall undergo, which increases the lifetime of the pipe. Equally, since the pipes are isolated from the surrounding environment by the bricks (rather than being embedded in concrete), any expansion and/or contraction of the pipes cause by temperature variations does not damage the surrounding wall (or the pipes). The bricks of the present invention are also insulating to sound which can be advantageous for the occupiers of the building.
• the bricks of the present invention also allow easy access to the pipes embedded in the wall for the purposes of maintenance (for example when a pipe is leaking or otherwise compromised).
• the brick protecting the pipes can be easily broken, revealing the pipes behind which can be repaired or replaced. This is much easier than breaking concrete, and does not risk damaging the pipes, since the pipes are isolated from the surrounding environment.

• the walls 104a,b,c have inner and outer surfaces corresponding to the inner and outer profiles of the 'U'-shaped cross-section.
• the chamfered corners of the inner profiles of the 'U'-shaped cross section define additional intermediary surfaces 108a and 108b.

• the channels 206 are evenly spaced from one other, by a distance greater than the width of the channels.
• the channels 206 facilitate the application and adhesion of mortar to the brick 200.
• the channels may also serve to improve the frangibility of the brick insofar as the brick is more likely to fracture along these channels when struck or otherwise has a pressure applied to it, due to the structural weaknesses introduced by the channels. This may assist when it is necessary to break a brick so as to repair a pipe, for example.
• the walls 204a, b,c are substantially hollow between their inner and outer surfaces.
• the walls 204a, b,c comprise a plurality of cavities 208 which extend longitudinally from the upper side 202 of the brick 200 to the bottom side of the brick.
• the cavities 208 are regularly spaced and have rectangular cross-sections. The majority of the cavities 208 have the same cross sections - a minority at the corners of the 'IT shape have smaller, square cross sections.
• the cavities 208 are separated from one another by inner walls 210 which are thinner than the length or width of the cavities 208.
• the walls 204a, b,c being substantially hollow (due to the presence of the cavities 208) reduces the weight of the brick and aids in the insulation of heat and sound by the brick. It also decreases the amount of material required to manufacture a brick.
• the presence of the cavities 208 can also increase the frangibility of the brick - in particular, if the cavities are too large, the walls 204a, b,c of the brick can become weak and/or crack, in addition to potentially being less insulating to heat and/or sound.
• the presence of inner walls 210 allows the walls 204a, b,c to retain an amount of structural strength while being frangible.
• the cross sections of the longitudinal channels 206 on the outer surfaces of the walls 204a, b,c of the brick can be seen in Figure 2b.
• the channels 206 have half- square profiles (which might be particularly easy to manufacture).
• the cross sections of the channels 206 could have rounded profiles.
• the inner walls 210 of the cavities 208 may be absent, such that the walls 204a, b,c comprise one continuous cavity between their inner and outer surfaces. This had the effect of potentially weakening the walls 204a,b,c of the brick 200, and/or providing less sound insulation.

• the brick 400 comprises an additional fourth wall 404d opposing the third wall 404c, substantially perpendicular to the opposing walls 404a and 404b and connecting the opposing walls.
• the brick 400 therefore has an essentially square cross section.
• the presence of a fourth wall 404d is for the purpose of production - if the fourth wall 404d is not added during production, then the other walls 404a, b,c can bend during the process of production and potentially lead to the brick being misshaped.
• the fourth wall 404d is suitable to be removed prior to installation.
• the fourth wall 404d is thinner than the other three walls 404a, b,c - this allows the fourth wall 404d to be cleanly broken off (with the other walls 404a, b,c remaining intact) prior to use of the brick 400 (i.e. its deployment in the construction of a wall). Breaking the fourth wall 404d in this way exposes the void 420 suitable for receiving a pipe. The fourth wall 404d is therefore sufficiently thin and frangible so as to be easily broken without damaging the remainder of the brick.
• a fourth wall 404d can also make the bricks easier to stack one on top of the other for the purposes of storage and/or transportation, for example.
• the fourth wall 404d can also prevent the brick 400 breaking during transportation.

• the brick is manufactured by an extrusion process which allows the efficient manufacturing of large volumes of bricks of a consistent size, shape, and quality.
• the brick 300 can be made from concrete or any other suitable material that has the desired properties.
• the brick has sufficient compressive strength to withstand the compressive forces present when deployed in a wall, but must also be frangible upon application of a sufficiently strong force (corresponding to being struck by a hand-held tool, for example).

• Bricks of differing dimensions can be employed together in order to better fill a gap left in a wall to accommodate pipes, or so as to avoid vertically aligning bricks which may be less stable.
• the walls 104a,b,c have thicknesses (between the inner and outer profiles of the 'IT shape) of around 1-5cm, preferably around 3cm.
• the thickness of the walls may depend on the dimensions of the brick, with thicker walls being appropriate for larger bricks.
