Definitions

• the invention relates to an interlockable wall reinforcement panel, a wall reinforcement assembly and a method for wall reinforcement.
• Damaged walls may show one or more different types of damage.
• a first type of damage is in-plane damage of the wall, which occurs when parts of the wall are displaced with regard to the other parts. This is often visible as cracks or fissures and can occur in brick walls, concrete walls and, in some cases, even in wooden structures such as timber frame constructions.
• a second type of damage is the out-of-plane damage, in which parts of the wall structure are displaced transversely to the side surface of the wall. This occurs most often in brick or concrete walls. It is noted that in some cases both types of damage may occur simultaneously in a single wall.
• reinforcement of damaged walls comes down to stabilizing the wall structure in-plane, out-of-plane or both by applying a (rigid) timber frame construction against a side, often the building inner side, of the wall.
• the timber frame is subsequently covered with wooden boards for support and plaster wall boards to provide a straight inner wall.
• Such a timber frame construction for wall reinforcement has several disadvantages.
• a timber frame construction has a relatively high thickness due to the posts that constitute the timber frame. As a result, the inner space of the building is decreased after the timber frame has been placed.
• many alterations are required to fit window and/or door posts, (plug)sockets and gas pipes to the new situation, which significantly increases costs.
• the invention is aimed at obviating or at least reducing the abovementioned disadvantages.
• the invention provides an interlockable wall panel for reinforcing walls, the panel having a wall panel surface extending in a plane defined by a first and a second direction, the wall surface having a number of side edges, wherein at least one of the number of side edges comprises:
• one or more indentations that extend in the plane and inwardly from the side edge, wherein the one or more indentations are configured to receive an associated projection of a second or further interlockable wall panel in a mating and interlocking connection that is configured to substantially prevent in plane-movement;
• one or more projections that extend in the plane and outwardly from the side edge, wherein the one or more projections are configured to be inserted into an associated indentation of the second or further interlockable wall panel in a mating and interlocking connection that is configured to substantially prevent in plane-movement; wherein the one or more projections and/or indentations are configured to be connectable to a second or further interlocking wall panel in a third direction.
• the third direction is substantially perpendicular to the plane and/or to the first and second directions.
• interlockable wall panel for wall reinforcement is used interchangeably with other similar wording, such as interlockable wall reinforcement panel, interlockable wall panel, wall panel and interlockable panel, and in general is directed to the same subject unless specifically noted otherwise.
• wording wall panel assembly may also be used interchangeably with the wording interlockable wall panel assembly, interlockable wall reinforcement panel assembly, wall assembly and panel assembly and in general is directed to the same subject unless specifically noted otherwise.
• An advantage of the interlockable wall panel according to the invention is that it has a relatively low thickness, when viewed in the third direction (i.e. perpendicular to the wall), thus leading to a relatively small increase in wall thickness after applying the wall panel. As a result, the cost for adapting window and/or door posts and/or (plug)socket connections to the (only slightly) increased wall thickness is significantly less than for existing solutions.
• Another advantage of the interlockable wall panel according to the invention is that, due to fact that the wall panel is connectable in the third direction, the wall panel (especially when connected with second and/or further wall panels) provides excellent stability both in-plane (parallel to the wall) and out-of-plane (perpendicular to the wall). As a result, an improved stability (or reinforcement) is achieved compared to known solutions.
• Another advantage of the interlockable wall panel according to the invention is that, due to the fact that the interlockable wall reinforcement panel according to the invention is connectable to a second or further wall panel in the third direction, the connection is not subjected to tension, stress or deformations during connecting. Although it would in theory be possible to provide a connection that is established in-plane, this would incur at least some stress and/or deformation in the material and would therewith reduce effectiveness of the wall panel. Because deformation does not occur when connecting the wall panel with a second or further wall panel in the third direction, a connection with improved safety is achieved.
• interlockable wall panel due to the fact that the interlockable wall reinforcement panel is connectable in the third direction, it provides a seamless fit of the projections and/or indentations between the wall panel and second or further wall panels.
• Another advantage of the interlockable wall panel according to the invention is that the wall panel is easy to connect to the wall that is to be reinforced.
• the wall panel according to the invention can be manufactured at relatively low cost, and may, for example, be manufactured at a central manufacturing plant.
• interlockable wall panel provides a flexible device for reinforcement of damaged walls and can be applied in most buildings.
• the wall panel may alternatively also be applied to reinforce ceilings and/or floors.
• the interlockable wall reinforcement panel may be combined with other interlockable wall reinforcement panels to construct a ‘box’ of panels that may reinforce both wall(s) and ceiling and/or floor.
• the interlockable wall panel may be manufactured based on a 3D-scan of the wall or walls to be reinforced.
• interlockable wall panels when manufactured based on a 3D scan of the wall or walls to be reinforced, provide several advantages.
• the interlockable wall panels are manufactured with high amount of precision, especially with regard to the dimensions of the panels required to cover the wall.
• Another advantage is that it allows a highly precise positioning of interlockable wall panels that are to be connected across walls that are at an angle with each other.
• Yet another advantage of the wall panels being manufactured based on a 3D-scan is that the wall panel or panels can be manufactured using pre-fab techniques. This allows a more efficient manufacturing while simultaneously providing a high-quality, precise fit on the wall that is to be reinforced.
• the wall panel may be combined with a number of standardized components, which increases production and delivery speed and reduces costs.
• the interlockable wall panel is not connectable in-plane, yet only connectable in the third direction, and thus not connectable in the first and/or the second direction.
• the interlockable wall panels are connectable to the wall that is to be reinforced using connections means, which for example may comprise screws, bolt-and-nut connectors or other suitable connection means.
• the wall panels Due to the low thickness of the interlockable wall panels (seen in the third direction), the wall panels can easily be connected to the wall that is to be reinforced. This may for example be provided with screws or bolt-and-nut connections, which provide a reliable and strong connection. Due to the fact that the interlockable wall panel is, in use, situated directly adjacent the wall, the connection means may in principle be applied at any location of the wall panel. This provides a significant improvement over the prior art solutions, which necessitates a connection to the timber frame.
• the one or more projections and/or one or more indentations extend, when measured in a third direction that is perpendicular to the plane, over an entire thickness of the interlockable wall panel.
• the interlockable wall panel may only connectable to the second or further interlockable wall panel in the third direction.
• the interlockable wall panel may comprise a single layer, or may comprise multiple layers.
• An advantage of the interlocking wall panel according to the invention is that it can be provided as a single layer or in multiple layers. In most cases, a single layer in itself already provides sufficient support to a damaged wall without substantially increasing the thickness of said wall.
• an even stronger reinforcement needs to be applied to reinforce the damaged wall.
• an interlocking wall panel with an increased thickness or multiple layers, often two layers, of interlocking wall panels are applied. This is especially interesting in case the different layers of wall panels are provided with different sizes of interlockable wall panels, which results in the interlocking projections and/or indentations being positioned at different places in the wall after placement.
• the interlockable wall panel may be manufactured from wood, metal, plastic or a combination of one or more thereof, and preferably may be manufactured from wood, wherein the wood preferably comprises multiplex, oriented strand board (OSB), cross-laminated timber (CLT) or glued laminated timber (GLT).
• OSB oriented strand board
• CLT cross-laminated timber
• GLT glued laminated timber
• An advantage of providing the abovementioned materials, and especially wood, is that they can easily be manufactured to the required specifications at a central location, such as a manufacturing plant.
• a thickness of the interlockable wall panel when measured in the third direction, may be in the range of 6 - 30 mm, preferably may be in the range 8 - 24 mm, and more preferably may be in the range of 12 - 18 mm.
• panels especially wood panels, having a thickness that is at any point in the range between 6 - 30 mm is usable to reinforce a wall.
• wall panels especially when made of wood or plastic, having a thickness in the range of 12 - 18 mm provide an excellent trade-off between the required reinforcement strength for the wall and the reduction of inner space of the building due to the increase in overall wall thickness.
• wood panels for building purposes are often manufactured in standard thicknesses, which include for example 12 mm and 18 mm.
• connection may be a slidable connection.
• the projection or indentation of the wall panel may be configured to be slidably inserted into an associated indentation or projection of a second or further wall panel.
• the at least one side edge may be provided with a plurality of indentations and projections that are alternately positioned along the side edge.
• An advantage of providing a side edge (or multiple side edges) with alternately positioned projections and indentations is that a (semi-)continuous series of projections and indentations is formed that provides a high in-plane and out-of-plane strength to the wall to be reinforced.
• Another advantage is that, due to the alternating pattern of projections and indentations, the wall panels can easily be positioned in the correct position with respect to each other before connection them to each other.
• At least two side edges, preferably opposing side edges, of the interlockable wall panel may be provided with one or more indentations and/or one or more projections.
• An advantage of providing multiple edges of an interlockable wall panel with one or more projections and/or indentations is that the wall panel can be connected to multiple adjacent wall panels, which provides a completely interlocked series of wall panels that may cover substantially the entire wall. This increased wall stability and improves the reinforcement.
• the interlockable wall panel may substantially be rectangular-shaped or may be substantially square-shaped.
• each side edge of the interlockable wall panel may be provided with a plurality of projections and a plurality of indentations that are alternately spaced along the side edge.
• interlockable wall panel according to the invention may be provided in substantially any shape, it is preferred to provide it as a rectangular or a square shape.

• an interlockable wall panel having such abovementioned shape can easily be connected with a mating connection of a second or further panel due to the similar shape.
• Another advantage is that rectangular or square interlockable wall panels are easy to transport from a manufacturing site to the place of use.
• the one or more projections may have a T-shaped profile, preferably in which the bottom of the T-shaped projection is connected to the side edge of the interlockable wall panel and extends therefrom.
• An advantage of the abovementioned shape is that allows a seamless fit with a corresponding (but oppositely shaped) indentation of a second or further wall panel (according to the invention).
• in-plane movement that is movement in the first and/or second direction, is substantially prevented and an improved wall stabilization is achieved.
• this shape also provides an increase of out-of-plane stability to the wall to be reinforced and increases resistance against (further) out-of-plane damage to the wall.
• T-shape provides several advantages over other shapes, including but not limited to, rectangular, (isosceles) trapezoid and square shapes.
• the T-shape has an improved resistance against disassociation of the connection, especially compared to square and rectangular shapes. This is mainly due to the fact that, when such connections, and especially the square and rectangular connection, are subjected to for example earthquake-induced forces, the connections provide insufficient holding force. This is especially true for sliding forces.
• the T-shape has been found to be especially resistant against earthquake induced damage compared to other types of shapes. This is mainly due to the fact that the T-shape provides multiple anti-failure mechanisms.
• the indentations have a T-shaped profile, preferably in which the T-shape extends inwardly from the side edge of the interlockable wall panel, and/or wherein the bottom of the T- shape is positioned at the side edge of the interlockable wall panel.
• An advantage of the abovementioned shape is that allows a seamless fit with a corresponding (but oppositely shaped) projection of a second or further wall panel (according to the invention). As a result of this seamless fit, in-plane movement, that is movement in the first and/or second direction, is substantially prevented and an improved wall stabilization is achieved.

• the indentations may have a trapezium-shaped profile, preferably in which the small base of the trapezium-shape is positioned at the side edge of the interlockable wall panel and the large base is positioned inwardly from the side edge, and more preferably wherein the trapezium-shape is a isosceles trapezium shape.
• An advantage of the abovementioned shape is that allows a seamless fit with a corresponding (but oppositely shaped) projection of a second or further wall panel (according to the invention). As a result of this seamless fit, in-plane movement, that is movement in the first and/or second direction, is substantially prevented and an improved wall stabilization is achieved.
