Description
Expansion floor joint
The present invention relates to the field of construction materials and techniques. and more particularly to techniques for creating an expansion joint in a concrete floor that allows for the natural expansion and contraction of the concrete without compromising the structural integrity of the floor.
Modern production and logistics companies require industrial flooring that is both functional and durable. Functionality is determined by the flooring’s ability to safely absorb loads from shelving, goods, machinery, and traffic, and is an essential part of stability verification. The flooring must also be fit for use, which requires a flat, wear-resistant base with minimal cracks and defects, and an optimized number of weak points, particularly in joint areas, to ensure low-
I5 maintenance and functional operation. Concrete is the most common material used for industrial flooring due to its numerous advantages.
However, designing joints between flooring fields can be problematic, as structural ruptures and damages can frequently occur in these areas, leading to reduced usability of the industrial flooring. The prior art includes solutions such as the expansion joint described in
EP2930268A1, which is mechanically robust and provides a highly reliable solution that avoids vibrations and neutralizes wheel impact. However, the expansion joint, by its very nature, is a gap between floors that gathers dirt and, in some cases, water, which may damage the integrity of the joint and flooring.
The expansion joint, while mechanically robust, is prone to damage from dirt and water ingress. This limits the durability and efficiency of the industrial flooring, which can lead to increased maintenance and replacement costs.
It is therefore an objective of the present invention to provide an expansion joint that substantially limits the ingress of dirt and water while maintaining its resilience against dynamic and static loads.
According to a first aspect, there is provided an expansion floor joint for use in a concrete floor. The expansion joint comprises at least a first profile element and a second profile element configured to engage a first slab and a second slab of the concrete floor, respectively. The first profile element and second profile element each comprise a corrugated plate portion configured to extend substantially vertically with respect to the concrete floor surface when the expansion floor joint is installed in the concrete floor. The expansion floor joint further comprises a sealing member, and at least one of the first profile element and the second profile element comprises a chamber portion provided near the top of the first profile element and the second profile element.
The chamber portion is shaped such that, when the expansion floor joint is installed in the concrete floor, a hollow chamber is formed between the first profile element and the second profile element.
The sealing member is arranged in the hollow chamber such that a space between the at least one of the first profile element and the second profile element is at least partially sealed.
One advantage of this arrangement is that the gap of the expansion floor joint is substantially sealed, thus eliminating water and dirt ingress. This feature provides a significant technical advantage to a person skilled in the art, as it reduces the risk of damage to the concrete floor and increases its lifespan. The chamber portion provided near the top of the first profile element and the second profile element may be understood as a cavity or hollow space within the profile element. It may be further provided that the sealing member is a compressible material, such as foam or rubber, which can adapt to the movement of the concrete floor due to temperature changes, settling, or other causes. This arrangement provides another technical advantage, as it allows the expansion floor joint to maintain its sealing properties over time, even in harsh conditions.
Preferably, each of the at least one of the first profile element and the second profile element comprises a chamber portion. This arrangement increases the size of the hollow chamber, thus providing a larger volume for the sealing member to compress and adapt to the movement of the concrete floor. Additionally, it simplifies the manufacturing process, as both profile elements can be made in substantially the same way, reducing costs and potential errors.
It may be further provided that the chamber portion is at least partially formed by a wall of the respective profile element, wherein said wall, seen along a cross-section, describes an arc such that the wall forms a curve between the corrugated plate portion and a distal end of the respective profile element. This arrangement provides a technical advantage, as the curved shape of the wall allows for a more efficient use of space within the profile element and provides a larger volume for the sealing member to compress and adapt to the movement of the concrete floor. Additionally, the curved shape of the wall can increase the flexibility and resilience of the expansion floor joint, making it better able to withstand external stresses and forces. Moreover, this arrangement avoids sharp corners which tend to be weak points in concrete solutions that are prone to breakage. The curved shape of the wall distributes stresses more evenly across the profile element, reducing the risk of cracking or damage. This feature contributes to the overall durability and reliability of the expansion floor joint, making it a desirable feature for use in concrete floors.
Preferably, a first slope angle of the wall near the distal end is larger than 30°, preferably larger than 40°, wherein the first slope angle is measured between an outer surface of the chamber portion near the distal end of the respective profile element and the concrete floor surface. A slope angle may be understood as the angle between the wall of the profile element and the concrete floor surface. In this way, the concrete near the edge of the distal end is supported by a substantial amount of concrete underneath. If the slope angle were too sharp, the concrete would crack under the stress of moving vehicles. This feature contributes to the overall stability and safety of the concrete floor, making it a desirable feature for the expansion floor joint. Furthermore, the larger slope angle of the wall near the distal end can also improve the overall flexibility and resilience of the expansion floor joint, making it better able to adapt to the movement of the concrete floor due to temperature changes, settling, or other causes. This feature provides another technical advantage, as it allows the expansion floor joint to maintain its sealing properties over lime, even in harsh conditions.
More preferably, a first slope angle of the wall near the distal end of the profile element is larger than a second slope angle of the wall near the corrugated plate portion, wherein the first slope angle is measured between an outer surface of the chamber portion near the distal end of the respective profile element and the concrete floor surface and wherein the second slope angle is measured between an outer surface of the chamber portion near the corrugated plate portion of the respective profile element and the concrete floor surface.
Preferably, the expansion floor joint comprises an integrally formed design for the chamber portion and the corrugated plate portion. This arrangement simplifies the manufacturing process and reduces the risk of errors or defects. The integrally formed design also results in a more robust structure.
Preferably, the expansion floor joint comprises an elastically deformable sealing member.
This allows the sealing member to adapt to the movement of the concrete floor due to temperature changes, settling, or other causes. The elastic deformability of the sealing member ensures that the expansion floor joint maintains its sealing properties over time, even in harsh conditions. This feature provides a more reliable and durable solution for concrete floors, reducing the risk of damage and maintenance costs.
Preferably, the sealing member comprises a sealing element configured to bridge a gap between the first profile element and the second profile element when the sealing member is arranged in the hollow chamber. This ensures that the gap between the first profile element and the second profile element is effectively sealed, preventing the ingress of water, dirt, or other materials that could potentially cause damage to the concrete floor. The sealing element can be made from a variety of materials, such as foam, rubber, or other suitable materials, and can be configured to conform to the shape and size of the gap, ensuring that the entire gap is sealed. This feature provides another technical advantage, as it allows the expansion floor joint to maintain its sealing properties even in the event of extreme external forces, such as heavy loads or seismic events.
More preferably, the sealing element is an upper sealing element configured to bridge the gap between the first profile element and the second profile element near the top of the first profile element and the second profile element inside the hollow chamber. One advantage of this arrangement is that it provides a more effective seal between the first profile element and the second profile element. By positioning the sealing element near the top of the first profile element and the second profile element, it is less likely that water or other substances will be able to penetrate the joint. Another advantage of this arrangement is that it may reduce the amount of maintenance required for the joint. By providing a more effective seal, it may be possible to reduce the amount of water and other substances that enter the joint, which may in turn reduce the amount of maintenance required to keep the joint in good condition.
Preferably, the sealing member further comprises a lower sealing element configured to bridge the gap between the first profile element and the second profile element near the corrugated plate portion of the first profile element and the second profile element inside the hollow chamber.
Preferably, the sealing member further comprises a sealing element connecting element which extends between the upper sealing member and the lower sealing member. The sealing element connecting element may be understood as a component that connects the upper sealing member and the lower sealing member together. This may help to ensure that the sealing element functions effectively as a single unit, and may also help to prevent any water or other substances from entering the joint between the first profile element and the second profile element. One advantage of this arrangement is that it may provide a more effective seal between the first profile element and the second profile element, particularly in areas where the joint may be more vulnerable due to the corrugated plate portion. This may help to further reduce the amount of maintenance required for the joint, as well as extend the overall lifespan of the joint.
It may be provided that the sealing member is monolithic, which means that it is formed as a single, integrated unit. This arrangement provides an additional layer of protection against the ingress of water and other substances into the joint, particularly in areas where the joint may be more vulnerable due to the corrugated plate portion. By forming the sealing member as a single, integrated unit, it may be possible to reduce the number of potential weak points or areas where water or other substances may be able to enter the joint. One advantage of this arrangement is that it may provide a more effective seal between the first profile element and the second profile element, particularly in areas where the joint may be more vulnerable due to the corrugated plate portion. This may help to further reduce the amount of maintenance required for the joint, as well as extend the overall lifespan of the joint.
Preferably, the sealing member comprises, seen in a cross section, a substantially O-shaped form. This means that the sealing member has a circular or oval shape when viewed in cross section, with an opening in the center that is configured to fit around the first profile element and the second profile element. By providing a circular or oval shape, the sealing member may be more 5 easily able to fit around the first profile element and the second profile element in an improved manner, and may be able to provide a more effective seal as a result.
Preferably, the sealing member is hollow, which means that it has an empty space or cavity inside. This may help to reduce the weight of the sealing member and make it easier to handle and install, while still providing an effective seal between the first profile element and the second profile element. The hollow construction of the sealing member also allows the sealing member to more easily adjust to the walls of the first and second profile element.
Preferably, the corrugated plate portion comprises a waveform shape. More preferably, the chamber portion of the first profile element and/or the second profile element comprises a waveform shape which corresponds to waveform shape of the respective corrugated plate portion shape. The waveform shape may be sinus-like.
Prefreably, the expansion floor joint further comprises at least a third profile element arranged below the first profile element and a second profile element.
Preferably, the third profile element is a corrugated profile element, wherein the corrugation of the third profile element is in antiphase with the corrugated plate portion of the first and second profile element. The at least third profile element may be secured to one of the first profile element and the second profile element through a binding member.
Preferably, the expansion floor joint further comprises an anchoring dowel. The anchoring dowel is preferably a continuous bridging dowel bridging the first profile element and/or the second profile element and the third profile element of said expansion joint and being accordingly connected at regular intervals to the first profile element or the second profile element and the third profile element of the expansion joint. The anchoring dowel may have alternating connection points at regular intervals to the respective the first profile element or the second profile element and the third profile element of the expansion joint.

The description of the exemplary embodiments shown in figures 1 and 2 can be used for figures 3, 4 andS.
In figures, I - 5 an expansion floor joint 100 for use in a concrete floor is shown. Concrete floors, particularly industrial concrete floors, are commonly used in various commercial and industrial buildings due to their durability and strength. Industrial concrete floors are typically made of a mixture of cement, water, and aggregates such as sand, gravel, or crushed stone. This mixture is poured into a prepared area of the building, where it is allowed to cure and harden into a solid, durable surface. One of the key advantages of concrete floors is their strength and durability.
They are able to withstand heavy loads and high levels of foot traffic, making them ideal for use in industrial settings. Concrete floors are also resistant to fire, water, and other environmental factors, making them a reliable choice for buildings in areas prone to natural disasters or extreme weather conditions. Another advantage of concrete floors is their low maintenance requirements. They are easy to clean and maintain, and do not require regular replacement or repairs. This can help to reduce overall maintenance costs for building owners and operators. Expansion floor joints are used in concrete floors to allow for the natural movement and expansion of the concrete due to temperature changes, settling, or other causes. Without expansion joints, the concrete floor would be more likely to crack or break due to the stress caused by this movement. Expansion floor joints are designed to accommodate the movement of the concrete floor by providing a gap or space between the slabs of the floor.
The expansion floor joint 100 comprises at least two profile elements 110, 120, namely the first profile element 110 and the second profile element 120. These profile elements are designed to engage with a first and second slab of the concrete floor (not shown), respectively. When a concrete floor is constructed, it is typically laid in sections or slabs. These slabs are separated by gaps or spaces to allow for natural expansion and contraction due to temperature changes or settling. The expansion floor joint 100 is placed in these gaps or spaces, with the first profile element 110 engaging with one slab and the second profile element 120 engaging with the adjacent slab. The first profile element 110 and the second profile element 120 are made of a durable material such as aluminium or steel. They are designed to withstand the weight and pressure of the surrounding concrete and to maintain their shape and position over time.
The first profile element 110 and second profile element 120 each comprise a corrugated plate portion 111, 121. The corrugated plate portion 111, 121 of each profile element extends vertically from the surface of the concrete floor, while the chamber portion 112, 122 is located near the top of the profile element. "Corrugated" refers to a material or surface that has a series of folds or ridges. In the context of the profile elements, the corrugated plate portion has a wavy surface with alternating ridges and valleys. The peaks and valleys may be uniform in size and shape, or they may vary in height and width. This design helps to increase the flexibility and strength of the joint, allowing it to expand and contract with changes in temperature and humidity without cracking or breaking. Also, this corrugation allows to continuously transfer a load when driving over the joint. The corrugated shape may be a waveform shape for example a sinus-like waveform as is shown in figures 1, 3, 5.
As shown in figures 1 — 5, at least one of the first profile element 110 and the second profile element 120 comprises a chamber portion 112, 122. For example, one of the first profile element 110 and the second profile element 120 can comprise of only a corrugated plate portion while the other of the first profile element 110 and the second profile element 120 can comprise a chamber portion. It can also be the case that both the first profile element 110 and the second profile element 120 comprise a chamber portion, as is illustrated in figures 1-5. This arrangement increases the size of the hollow chamber, thus providing a larger volume for the sealing member to compress and adapt to the movement of the concrete floor. Additionally, it simplifies the manufacturing process, as both profile elements can be made in substantially the same way, reducing costs and potential errors. The chamber portion 112, 122 is provided near the top of the first profile element and the second profile element. When the expansion floor joint is installed in a concrete floor, the chamber portions 112, 122 of the first and second profile elements are positioned facing each other. This creates a space or hollow chamber between the two elements that runs the length of the joint.
The floor joint 100 further comprises a sealing member 130. The sealing member 130 is arranged between the first profile element 110 and the second profile element 120, within the hollow chamber formed by the chamber portion 112, 122. The compressible nature of the sealing member 130 allows it to adapt to the movement of the concrete floor, ensuring that the space between the profile elements is at least partially sealed. This helps to prevent water, dirt, and other materials from entering the space between the slabs, which can cause damage to the concrete floor over time. Overall, the use of the first profile element 110 and second profile element 120 in the expansion floor joint 100 allows for natural movement and expansion of the concrete floor, while maintaining the stability and safety of the floor. The sealing member 130 ensures that the joint remains sealed, preventing damage to the concrete floor and extending its overall lifespan. T
It may be further provided that the chamber portion 112, 122 is at least partially formed by a wall of the respective profile element, as is shown in figures 1 - 4. Said wall, seen along a cross- section, describes an arc such that the wall forms a curve between the corrugated plate portion 111, 121 and a distal end 120d of the respective profile element, see figure 2. This arrangement provides a technical advantage, as the curved shape of the wall allows for a more efficient use of space within the profile element and provides a larger volume for the sealing member to compress and adapt to the movement of the concrete floor. Additionally, the curved shape of the wall can increase the flexibility and resilience of the expansion floor joint, making it better able to withstand external stresses and forces. Moreover, this arrangement avoids sharp corners which tend to be weak points in concrete solutions that are prone to breakage. The curved shape of the wall distributes stresses more evenly across the profile element, reducing the risk of cracking or damage. This feature contributes to the overall durability and reliability of the expansion floor joint, making it a desirable feature for use in concrete floors. The distal end 120d of the respective profile element is situated near the concrete surface or aligned with it. This means that when the expansion floor joint 100 is installed in a concrete floor, the distal end of each profile element is positioned flush with the surface of the floor, allowing for a smooth and even transition between the joint and the surrounding floor. This helps to prevent tripping hazards and damage to vehicles or equipment that may pass over the joint.
In Figure 2 of the expansion floor joint 100, it is shown that the wall of the respective profile element has a slope angle a near the distal end. This slope angle is preferably larger than 30° and, ideally, larger than 40°. The slope angle is measured between the outer surface of the chamber portion near the distal end of the profile element and the concrete floor surface. A larger slope angle is advantageous because it determines the amount of support that the concrete floor. A larger slope angle means that the concrete near the edge of the distal end is supported by a substantially amount of concrete underneath. This is important because if the slope angle were too sharp, a substantially smaller portion of the concrete would be put under stress and could crack under the weight of moving vehicles. Therefore, the larger slope angle contributes to the overall stability and safety of the concrete floor, making it a desirable feature for the expansion floor joint. More preferably, a first slope angle of the wall near the distal end of the profile element is larger than a second slope angle of the wall near the corrugated plate portion, wherein the first slope angle is measured between an outer surface of the chamber portion near the distal end of the respective profile element and the concrete floor surface and wherein the second slope angle is measured between an outer surface of the chamber portion near the corrugated plate portion of the respective profile element and the concrete floor surface.
Figures 1-4 show that the expansion floor joint 100 comprises an integrally formed chamber portion and corrugated plate portion. This means that the chamber portion 112, 122 and the corrugated plate portion 111, 121 are combined into a single, seamless unit. An alternative design for an expansion floor joint could be to have separate chamber and corrugated plate portions that are connected to each other, see for example figures 5. In this case, the chamber portion 111, 121 could be a separate element that is attached to the corrugated plate portion 112, 122, rather than being formed as an integral part of it. Another alternative design could be to have a chamber portion 112, 122 that is not integrally formed with the profile element, but is instead a separate unit that is inserted into the joint after the profile elements have been installed. In this case, the chamber portion could be made of a flexible material that is able to expand and contract with the joint, while still providing a secure seal between the profile elements.
Figures 1-4 further show that the floor joint 100 comprises a sealing member 130. Figures 1-2 show a sealing member 130 with a substantially O-shaped form, seen in a cross section.
Figures 3-4 show a sealing member with an H-like form. In all exemplary embodiments it is preferred that the expansion floor joint 100 comprises an elastically deformable sealing member 130. The sealing member 130 allows the joint to adapt to the movement of the concrete floor due to temperature changes, settling, or other causes. The ¢lastic deformability of the sealing member 130 ensures that the expansion floor joint maintains its sealing properties over time, even in harsh conditions. This feature provides a more reliable and durable solution for concrete floors, reducing the risk of damage and maintenance costs, The elastic deformability of the sealing member is important because it allows the joint to accommodate the natural movement of the concrete floor.
Concrete floors can experience significant movement due to temperature changes, settling, or other causes, and if the sealing member was not able to stretch and compress with the movement of the floor, it could become damaged or dislodged, leading to leaks or other issues. By using an elastically deformable sealing member 130, the expansion floor joint is able to maintain a secure and reliable seal over time, reducing the risk of damage and maintenance costs. An alternative design for an expansion floor joint could be to use a non-elastic sealing member 130, such as a rigid or semi-rigid material. While these materials may provide an initial seal, they may not be able to adapt to the movement of the floor over time, leading to leaks or other issues. Another alternative could be to use a compressible foam material as a sealing member or a combination thereof. While foam materials can expand and contract with the movement of the floor, they may not provide the same level of durability and reliability as an elastically deformable material. the sealing member is monolithic, meaning that it is formed as a single, integrated unit. This arrangement provides an additional layer of protection against the ingress of water and other substances into the joint, particularly in areas where the joint may be more vulnerable due to the corrugated plate portion. By forming the sealing member 130 as a single, integrated unit, it may be possible to reduce the number of potential weak points or areas where water or other substances may be able to enter the joint. One advantage of this arrangement is that it may provide a more effective seal between the first profile element 110 and the second profile element 120. An alternative design for an expansion floor joint 100 could be to use a sealing member that is not monolithic, such as one that is made up of multiple components that are connected together. While this design may still provide a reliable seal, there may be more potential weak points or areas where water or other substances could enter the joint. Another alternative could be to use a separate sealing material or compound to fill the gaps between the first and second profile elements. While this approach may be effective, it requires more maintenance over time.
As described here above, figures 1-2 show that the sealing ember 130 can have a substantially O-shaped form when viewed in cross section. This means that the sealing member has a circular or oval shape. The circular or oval shape of the sealing member allows it to fit more easily in the profile elements and provides a more effective seal. By having an O-shaped form, the sealing member can form a complete loop in the chamber of the profile elements, providing a substantially continuous barrier against the ingress of water and other substances. The shape also allows the sealing member 130 to compress and expand as needed to accommodate movement in the concrete floor, while still maintaining a secure seal. it is preferred for the sealing member to be hollow, meaning it has an empty space or cavity inside. The hollow construction of the sealing member has several advantages. Firstly, it reduces the weight of the sealing member, making it easier to handle and install. Secondly, the hollow construction allows the sealing member to more easily adjust to the walls of the first and second profile elements, ensuring a more secure and effective seal. The hollow construction of the sealing member 130 also allows for more flexibility and adaptability to changes in temperature and humidity, as the air inside the cavity can expand and contract with changes in temperature, without causing damage to the sealing member or the joint.
Additionally, the hollow space provides an additional buffer zone for any debris or water that may enter the joint, which can help to prevent damage to the surrounding concrete floor. An alternative design for an expansion floor joint 100 could be to use a sealing member 130 that is solid, rather than hollow. While a solid sealing member 130 may also provide an effective seal, it may be more difficult to handle and install due to its weight, and may be less adaptable to changes in temperature and humidity.
An alternative design to the O-shaped sealing member 130 for an expansion floor joint could be to use a sealing member with a different shape, such as the H-like shape shown in figure 3 and 4. Although, the following features are described in relation to the H-like shaped sealing member 130, the same or similar features are identified in figures 1-2. Preferably, the sealing member 130 comprises a sealing element 131 configured to bridge a gap between the first profile element 110 and the second profile element 120 when the sealing member 130 is arranged in the hollow chamber. This ensures that the gap between the first profile element 110 and the second profile element 120 is effectively sealed, preventing the ingress of water, dirt, or other materials that could potentially cause damage to the concrete floor. The sealing element 130 can be made from a variety of materials, such as foam, rubber, or other suitable materials, and can be configured to conform to the shape and size of the gap, ensuring that the entire gap is sealed. This feature provides another technical advantage, as it allows the expansion floor joint to maintain its sealing properties even in the event of extreme external forces, such as heavy loads or seismic events.
More preferably, the sealing element 131 is an upper sealing element 131 configured to bridge the gap between the first profile element 110 and the second profile element 120 near the top of the first profile element 110 and the second profile element 120 inside the hollow chamber, i.e. near the distal end of the expansion joint 100. One advantage of this arrangement is that it provides a more effective seal between the first profile element and the second profile element. By positioning the sealing element near the top of the first profile element and the second profile element, it is less likely that water or other substances will be able to penetrate the joint. Another advantage of this arrangement is that it may reduce the amount of maintenance required for the joint. By providing a more effective seal, it may be possible to reduce the amount of water and other substances that enter the joint, which may in turn reduce the amount of maintenance required to keep the joint in good condition. The sealing member 130 may further comprise a lower sealing element 132 configured to bridge the gap between the first profile element and the second profile element near the corrugated plate portion of the first profile element and the second profile element inside the hollow chamber. The lower sealing element 132 is designed to provide an additional layer of protection against the ingress of water and other substances into the joint. By including a lower sealing element that bridges the gap between the profile elements near the corrugated plate portion, the sealing member can provide a more secure and reliable seal, even in areas where the joint may be more vulnerable. An alternative design for an expansion floor joint could be to use a sealing member without a lower sealing element. While this may still provide a reliable seal, it may not be as effective in areas where the joint is more vulnerable due to the corrugated plate portion.
The sealing member 130 may further comprises a sealing element connecting element 133 which extends between the upper sealing member and the lower sealing member. The sealing element connecting element is a component that connects the upper and lower sealing members together. This helps to ensure that the sealing element functions effectively as a single unit, and may also help to prevent any water or other substances from entering the joint between the first profile element and the second profile element. The sealing element connecting element 133 helps to provide additional support and stability to the sealing member, and helps to ensure that the upper and lower sealing members remain aligned and in place. This can be particularly important in areas where the joint may be more vulnerable due to the corrugated plate portion of the first and second profile elements. An alternative design for an expansion floor joint could be to use a sealing member without a sealing element connecting element, for example in the illustrated exemplary embodiment of figures 1 and 2. While this may still provide a reliable seal, it may not be as effective in areas where the joint is more vulnerable due to the corrugated plate portion, and there may be a greater risk of the upper and lower sealing members becoming misaligned or dislodged.
In figure 5 is shown that the first profile element and a second profile element can be used together with at least a third profile element 140 arranged below the first profile element and a second profile element. The use of a third profile element can help to provide additional support and stability to the joint, particularly in areas where the joint may be more vulnerable due to the corrugated plate portion of the first and second profile elements. The third profile element can help to distribute the weight and pressure of the joint more evenly, reducing the risk of damage or wear over time. Preferably, the third profile element 140 is a corrugated profile element (not shown), wherein the corrugation of the third profile element is in antiphase with the corrugated plate portion of the first and second profile element. The at least third profile element may be secured to one of the first profile element and the second profile element through a binding member.
Preferably, the expansion floor joint 100 further comprises an anchoring dowel 160. The anchoring dowel is preferably a continuous bridging dowel bridging the first profile element and/or the second profile element and the third profile element of said expansion joint and being accordingly connected at regular intervals to the first profile element or the second profile element and the third profile element of the expansion joint. The anchoring dowel may have alternating connection points at regular intervals to the respective the first profile element or the second profile element and the third profile element of the expansion joint.
