[0003] "Building impact protection device with a core and a protective layer"

[0004] The invention relates to a building impact protection device for protecting a building wall, in particular a cold room wall impact protection device and / or a hygiene wall impact protection device, wherein the building impact protection device has at least one core and a protective layer, wherein the core is designed as a cured polymer resin core, according to claim 1 and a method according to claim 14.

[0005] State of the art

[0006] Building impact protection devices for protecting building walls, such as cold storage wall impact protection and / or hygiene wall impact protection, are already commercially available in a wide variety of designs. These are usually mounted on the walls and are often approximately 25-50 cm high and 3-10 cm deep / thick, so that, for example, hand trucks, forklifts, or similar vehicles cannot damage the walls. This means that the walls do not require a particularly robust or solid surface and can be manufactured relatively inexpensively. The building impact protection device or base, on the other hand, should be particularly robust to prevent damage upon impact. Damage, especially in hygienic environments such as cold storage rooms, food storage areas, slaughterhouses, hospitals, or similar facilities, can lead to unacceptable bacterial contamination, which violates legal regulations.

[0007] These building impact protection devices typically consist of a concrete core with or without a metal protective casing. The metal sheet, usually made of stainless steel, reduces damage to the core and can improve hygiene.

[0008] However, practical experience has shown that over time, impacts, forces, or similar factors can cause the protective or metal layer to detach from the core. Therefore, damaged crash barriers must be replaced, which is a complex and costly process. Patent application filed by: coldwork GmbH & Co. KG. Date: November 14, 2025.

[0009] Purpose and advantages of the invention

[0010] In contrast, the object of the invention is to propose a building impact protection device or a corresponding manufacturing process, whereby at least some of the disadvantages of the prior art are improved, in particular ensuring safe hygienic operation or a long service life.

[0011] This problem is solved, starting from a building impact protection device or a method of the type mentioned in the introduction, by the features of claim 1 or 17. Advantageous embodiments and further developments of the invention are possible by the measures mentioned in the dependent claims.

[0012] Accordingly, a building impact protection device according to the invention for protecting a building wall, in particular a cold room wall impact protection device and / or a hygiene wall impact protection device, comprises at least one core and a protective layer, wherein the core is designed as a cured polymer resin core, wherein the protective layer is designed at least partially as the outer shell layer of the building impact protection device, characterized in that the protective layer is designed as a fiber-reinforced plastic layer (FRP) with reinforcing fibers and a cured plastic matrix, and that at least one adhesive layer is provided between the core and the protective layer for bonding the core to the protective layer, so that the core is bonded to the protective layer, for example, bonded over the entire surface.

[0013] For example, the building impact protection device is designed and intended to be positioned in front of a building wall and / or adjacent to a building wall in order to protect the building wall from being struck, for example by a vehicle such as a forklift or pallet truck.

[0014] In the inventive method for manufacturing such a building impact protection device, the polymer resin core is bonded to the fiber-reinforced plastic layer (FRP), in particular to the glass fiber plastic layer (GFRP), especially bonded over the entire surface.

[0015] The process for manufacturing the building impact protection device may comprise one or more of the following process steps, whereby the sequence of the process steps may also be varied: Patent application Applicant: coldwork GmbH & Co. KG Status: 14.11.2025 Our reference: ST 4801-PC-ERW / RA - 3 -

[0016] - Introducing a first protective layer into a mold for the building impact protection device

[0017] - Roughening of the first surface of the first protective layer

[0018] - Applying or coating a first layer of adhesive onto the first surface of the first protective layer

[0019] - Applying or coating polymer resin onto the first protective layer

[0020] - Roughening of a first surface of a second protective layer

[0021] - Applying a second layer of adhesive to the first surface of the second protective layer

[0022] - Applying the second protective layer to the polymer resin so that the second adhesive layer is in contact with the polymer resin

[0023] - Applying a force to the second protective layer

[0024] - Allow the polymer resin and the adhesive to cure so that the protective layers form an integral unit with the polymer resin.

[0025] It is also conceivable that the procedure includes one or more of the following procedural steps:

[0026] - Joining the protective layers with a sealant joint

[0027] - Creating a recess in the polymer resin core to accommodate a shear force frame unit

[0028] - Introducing a concave section into the polymer resin core

[0029] For example, the protective layer is first placed in a mold. Then, for example, the adhesive layer is applied to a surface of the protective layer, and subsequently the polymer resin is poured into the mold, for example, onto the adhesive layer. For example, a polymer adhesive, in particular a bonding adhesive, is used for the adhesive layer. For example, the adhesive layer and / or the polymer adhesive and / or the bonding adhesive is designed as a cured or curable polymer adhesive, in particular as a cured or curable bonding adhesive. In a further step, another protective layer, which is provided with another adhesive layer, can be applied to the polymer resin, so that the additional adhesive layer is present between the polymer resin and the additional protective layer. This makes it possible, for example, to create a sandwich structure for the building impact protection device.It is also conceivable that a third protective layer is incorporated into the mold, which, for example, forms the top surface of the building impact protection device. Patent application filed by: coldwork GmbH & Co. KG, dated: November 14, 2025. Our reference: ST 4801-PC-ERW / RA - 4 -.

[0030] It is also conceivable that the surface of the protective layer is roughened mechanically and / or chemically before the adhesive layer is applied. This results in improved bonding between the adhesive layer and the protective layer.

[0031] With the aid of the fibers in the fiber-reinforced plastic layer according to the invention, a hygienic surface or a surface that is easy to clean and / or sterilize can be achieved, and the tensile strength of the protective layer is also increased. This makes it possible to achieve a particularly tear-resistant and stable embodiment of the protective layer. At the same time, good elasticity of the protective layer is also ensured, so that, for example, in the event of an impact or collision, the protective layer can deform without causing any impairment and can return to its original shape. This is particularly important in combination with the core, which is designed as a cured polymer resin core, since this core can also deform or yield elastically to a certain extent. The adhesive layer is also of crucial importance here, as it too can deform or yield elastically to a certain extent.It can provide an elastic mediation between the two layers / components. This represents a complete departure from the previous design of building impact protection devices with an inelastic and porous concrete core and a physically anchored metal protective layer.

[0032] The inventive design of the building impact protection device, particularly with an adhesive layer between the core and the protective layer for bonding the core to the protective layer, enables, for example, a slight elastic cushioning of an impact or collision. According to the invention, the energy can be absorbed without causing damage or impairment, such as cracking or flaking of concrete fragments as occurs in the prior art, to the building impact protection device and / or the core and / or the protective layer. This effectively prevents the formation of unhygienic surfaces that are difficult or impossible to keep sterile and can no longer meet hygienic requirements.

[0033] The protective layer, designed as a fiber-reinforced plastic layer, consists, for example, of reinforcing fibers and a plastic matrix. The matrix surrounds the fibers, which are bound to the matrix, for example, by adhesive interactions. These fibers can be arranged in an ordered or disordered manner within the matrix. (Applicant: coldwork GmbH & Co. KG, Status: November 14, 2025, Our reference: ST 4801-PC-ERW / RA - 5 -)

[0034] The arrangement of fibers, as in a woven fabric, braid, or similar structure, results in direction-dependent elasticity and tensile strength behavior, which can be aligned, for example, with the expected main load or stress direction. This further improves stability and service life.

[0035] For example, the polymer resin core is designed as a synthetic resin mortar with at least one polymeric, hardened binder and a mineral filler, the filler being at least partially composed of aggregate. It has been shown that the synthetic resin mortar core, in particular, exhibits special properties such as low porosity, water impermeability, diffusion resistance, frost resistance, very high chemical resistance, a smooth surface, high tensile strength, high flexural strength, and / or high compressive strength, as well as, above all, good damping properties. This allows the synthetic resin mortar core to absorb and withstand impacts with exceptional flexibility, without impairing the building's impact protection system. Furthermore, the aforementioned properties, such as frost resistance, are essential, especially in applications with high hygiene requirements and / or temperature loads, such as in cold storage / freezer rooms.

[0036] For example, the synthetic resin mortar includes at least one additional reinforcement layer with plastic macrofibers to increase flexural strength and stability. This further improves the use of the building impact protection device, especially for hygienic applications.

[0037] For example, the fiber-reinforced plastic layer is designed as a glass fiber reinforced plastic (GFRP) layer, with the reinforcing fibers being at least partially glass fibers. It has been shown that the glass fiber reinforced plastic, in combination with a (suitable) plastic matrix, exhibits particularly high elongation at break and high elastic energy absorption, but also a relatively low modulus of elasticity. This allows the building impact protection device to meet particularly high stiffness requirements while simultaneously absorbing and cushioning impacts and similar events. In addition, the glass fiber reinforced plastic also exhibits excellent corrosion resistance in aggressive environments and can thus meet high hygiene standards over a long service life.

[0038] For example, the protective layer is plate-shaped, e.g., in the form of a flat or planar plate. It is conceivable that the building impact protection device has two or more protective layers in the form of plates. For example, the building impact protection device has a protective layer on a front and a back. It is also conceivable that the building impact protection device has a protective layer on a top surface. It is conceivable that two protective layer plates are joined by a sealant joint, e.g., an elastomer joint. For example, the various protective layer plates form the outer casing layer of the building impact protection device.

[0039] For example, the fiber-reinforced plastic layer comprises at least two protective layer plates, with at least one sealant joint between the two protective layer plates. The sealant joint can be, for example, an elastomeric joint and / or a hinge-like element. It is conceivable that the sealant joint is permanently elastic. However, it is also conceivable that the sealant joint is hard or brittle. It is also conceivable that the fiber-reinforced plastic layer and / or the at least two protective layer plates are straight or planar and, in particular, without bends or curves.

[0040] The sealant joint allows the two (or separate) protective layer plates to move or pivot relative to each other. This enables the fiber-reinforced plastic layer, or the two (separate) protective layer plates, to move relative to each other or independently. This is particularly important in the event of a strong impact or collision, where the slightly elastic polymer core deforms slightly, for example, the front edge being indented while the top surface remains largely unaffected.

[0041] In general, sealant joints of the building impact protection device ensure a hygienic connection between two adjacent protective layer panels or the entire outer surface of the building impact protection device, as well as an aesthetically pleasing appearance.

[0042] The special relative adjustability / mobility / pivotability between two adjacent protective layer plates, e.g., a front protective layer plate and an upper end or top protective layer plate, can, in the event of a collision or impact, e.g., with a forklift or similar vehicle, lead to indentation / deformation of the first or front protective layer plate, so that the edge of this plate shifts / pivots relative to the second / other / adjacent protective layer plate, e.g., the upper end or top protective layer plate, without any adverse force being transmitted to the second / other protective layer plate. This is achieved precisely through the bonding or...The adhesive layer ensures that the first and / or second protective layer plate does not detach from the core. This decoupling of the two adjacent protective layer plates, e.g., a front protective layer plate and an upper end or top protective layer plate, represents a complete departure from previous protective layers made of curved metal protective layers that were usually physically anchored to / in / with the core.

[0043] For example, the adhesive, e.g., the adhesive layer, is designed as a polymer adhesive layer, and in particular, the polymer adhesive layer is designed as a composite adhesive. For example, the adhesive layer and / or the polymer adhesive layer and / or the composite adhesive is designed as a cured or curable polymer adhesive, in particular as a cured or curable composite adhesive. This creates a special, for example, chemical and / or physical, adhesion between the core and the protective layer, which can also be elastically deformable.

[0044] For example, a protective layer, e.g., in the form of a protective layer plate, is applied / bonded at least partially to at least one front and one back of the core, and, for example, to one top edge of the core. For instance, the upper end face or the upper end / top / top protective layer plate is inclined or angled / acutely oriented with respect to the horizontal plane. This ensures that the building impact protection device is both well protected and stable, while also allowing liquids to drain away effectively, thus meeting particularly high hygiene requirements.

[0045] For example, an adhesive layer is provided on at least one front and one back of the core. For example, an adhesive layer is provided on one top side of the core between the protective layer and the core. It has been shown that bonding the core to the protective layer at the front and back, and possibly also on the top, further improves the stability and durability of the building impact protection device. Patent application. Applicant: coldwork GmbH & Co. KG. Date: November 14, 2025. Our reference: ST 4801-PC-ERW / RA - 8 -

[0046] A second adhesive and / or a second (full-surface) adhesive layer can be applied between the core of the building impact protection device and the wall to which the device is attached or mounted, or to an additional protective layer. This can be particularly helpful and improve durability and lifespan.

[0047] For example, at least one end face of the building impact protection device has a stop element to absorb lateral forces extending in the longitudinal direction of the device. This stop can be provided, for example, on two opposing end faces. This allows the building impact protection device to be securely and permanently anchored to the wall and / or to absorb particularly high lateral forces. This is helpful, for example, in the case of particularly large impact loads.

[0048] For example, a shear force frame unit is provided. The shear force frame unit can, for example, have a stop or stop element on one or both sides of the lateral end face of the building impact protection device or its core. This shear force frame unit and / or the stop element can be firmly fixed to the wall and / or floor on which the building impact protection device is to be mounted or positioned, for example, by means of screws and / or anchors. For example, the shear force frame unit extends over a length of the building impact protection device in its longitudinal direction. It is conceivable that the shear force frame unit extends completely over the length of the building impact protection device in its longitudinal direction.

[0049] For example, the shear force frame unit is L-shaped. It is conceivable that the shear force frame unit can be mounted with one side resting on or standing on a floor surface of the building. For example, the shear force frame unit can be positioned with the other side abutting a building wall. It is also conceivable that the first and second sides of the shear force frame unit are angled relative to each other, e.g., at 90°. For example, the stop element forms a cross brace between the first and second sides, so that the first side is supported by the stop element on the second side and vice versa. Patent application. Applicant: coldwork GmbH & Co. KG. Date: November 14, 2025. Our reference: ST 4801-PC-ERW / RA - 9 -

[0050] For example, this shear frame unit and / or the stop element is made of metal, e.g., stainless steel such as V2A. The building impact protection device and / or the core may have a recess, step, or ledge that can accommodate the shear frame unit and / or the stop element, e.g., in a form-fitting manner. For example, the shear frame unit is bonded to the core, e.g., directly, using an adhesive. This allows the core to be bonded and / or fixed to the wall and / or floor in a particularly stable manner. It is also conceivable that the core and / or the protective layer are simply connected to the shear frame unit by being plugged together. For example, the building impact protection device is designed so that the shear frame unit can first be installed in the building, and then the core can be placed onto or against the shear frame unit, e.g., in a form-fitting manner.

[0051] For example, a cross-section of the building impact protection device and / or the core has a concave section at least at one end. For example, a longitudinal axis of the concave section extends along the length of the building impact protection device and / or the core. For example, the concave section is present as a cylindrical or tubular recess in the building impact protection device. For example, the lower end / edge region of the building impact protection device and / or the core, and / or a front face of the building impact protection device and / or the core, includes the concave section when the building impact protection device is installed.

[0052] For example, the concave section of the building impact protection device, when installed, is designed as the outer surface and / or outer face of the device. It is conceivable that the concave section extends along the length of the building impact protection device. For example, the core forms the outer surface of the concave section. This means that no protective layer may be bonded to the concave section. For example, at least the protective layer and the adhesive layer, or at least one of the two (flat) protective layer plates, in particular the front protective layer plate, projects beyond the entire concave section, for example, completely, when the building impact protection device is installed. For example, at least one of the two protective layer plates, in particular the front protective layer plate, is designed as a flat or...Planar protective layer plate formed. Thus, in the case of patent application, applicant: coldwork GmbH & Co. KG, date: November 14, 2025, our reference: ST 4801-PC-ERW / RA - 10 -.

[0053] If necessary, for example when subsequently installing or implementing a floor coating such as a screed floor with flooring or the like, the concave section should be at least partially filled with this floor coating. This creates a cove at the bottom of the building impact protection device, which significantly improves its hygiene.

[0054] For example, the building impact protection device is designed as a multi-layer building impact protection device with a core, a first protective layer on a front side of the core, a first adhesive layer between the first protective layer and the core, a second protective layer on a back side of the core, and a second adhesive layer between the second protective layer and the core. For example, a third protective layer is also arranged on a top side of the core, with a third adhesive layer being provided, in particular, between the third protective layer and the core. It has been shown that this embodiment can meet particularly high requirements for stability, service life / durability, and hygiene.

[0055] In principle, for example, the building impact protection device and / or the multi-layer building impact protection device can be designed as a single unit with a building wall contact surface for contacting and / or bonding to a building wall and / or building floor. This makes it prefabricated or manufactured so that the separately handled unit can be attached to the building wall, in particular with an adhesive or adhesive layer, e.g., a polymer adhesive such as a bonding adhesive or the like.

[0056] Example of implementation

[0057] An embodiment of the invention is shown in the drawing and is explained in more detail below with reference to the figures. Patent application filed by: coldwork GmbH & Co. KG, dated November 14, 2025. Our reference: ST 4801-PC-ERW / RA - 11 -

[0058] Specifically, we show:

[0059] Figure 1 schematic cross-sectional views of two variants of a building impact protection device according to the invention and

[0060] Figure 2 is a schematic, perspective representation of the variant according to Figure 1 a).

[0061] A building impact protection device 1 according to Figures 1 and 2 comprises a core 2, in particular a synthetic resin mortar core, e.g. with optional plastic macrofibers, and a protective layer 3. The protective layer 3 consists, e.g., of glass fiber reinforced plastic (GFRP) and is, e.g., approximately 3 mm thick, and in the two exemplary variants according to Figure 1, each comprises three separate or individual protective layer plates 4, i.e., a front plate 4, a top plate 4, and, e.g., a back plate 4. The underside of the building impact protection device 1 does not have a protective layer in these variants, although an underside plate (not shown) can optionally be provided here as well.

[0062] Between the core 2 and the protective layer 3 or the protective layer plates 4, an adhesive layer 5, for example a full-surface layer, or a first adhesive 5, is provided, which chemically bonds or glues the core 2 and the protective layer 3 or protective layer plates 4 together. The adhesive layer 5 or the first adhesive 5 can, for example, be designed as a water-resistant bonding adhesive 5.

[0063] Furthermore, a sealant joint 6, for example consisting of a two-component sealant, is provided between two adjacent protective layer panels 4 or between the front panel 4 and the top panel 4, thus creating a hygienic exterior surface. In the installed state of the building impact protection device 1, silicone joints and / or sealant joints 7 can also be provided as connections to a wall 8 and a floor 9 of the building, thus ensuring a hygienic connection of the building impact protection device 1 to the building. The sealant joints 6, 7 can be designed as a permanently elastic seal and / or as a hard seal, e.g., brittle.

[0064] For example, the building impact protection device 1 is glued to the wall 8 with a second adhesive 10, in particular a mounting adhesive 10. This adhesive covers the entire back of the building impact protection device 1 and can be applied, for example, in spots, strips or over the entire surface. (Intelligence application Applicant: coldwork GmbH & Co. KG Status: 14.11.2025 Our reference: ST 4801-PC-ERW / RA - 12 - )

[0065] Furthermore, a variant of the building impact protection device 1 is shown, the rear plate 4 of which is designed such that no protective skin 3 is present in the lower area, but rather a cutout 14 or recess 14 in accordance with the invention, so that a shear force frame unit 11 or a so-called shear force shoe 11 of the building impact protection device 1 can be inserted or arranged here, e.g., in a form-fitting manner. This can absorb particularly large shear forces and can have a triangular stop 12 laterally or at the end face with respect to a longitudinal direction of the building impact protection device 1. This shear force frame unit 11 is, for example, in turn glued to the core 2 and / or the wall 8 and / or the floor 9, for example with the second adhesive 10 or assembly adhesive 10.

[0066] The shear frame unit 11 is connected to the building, for example, to the ground 9 in its assembled state, by means of an anchor 13, e.g., a heavy-duty anchor made of, for example, V2A stainless steel. Likewise, if required, e.g., in cases where a floor coating (not shown) is subsequently applied, the building impact protection device 1 can have a concave section in its front, lower area, e.g., in the form of a cove 15, which extends longitudinally along the building impact protection device 1 and in which case no protective layer 3 or protective layer plate 4, i.e., no front plate 4, is present. However, it is also conceivable that the building impact protection device 1 always has a cove 15 for hygienic reasons.This has the advantage that in the lower area the building impact protection device 1 is offset inwards, so that contact with a vehicle is advantageously reduced in this area, which leads to a longer service life of the lower sealant joint 7 and thus to improved hygiene.

[0067] The dimensions or millimeter measurements given in the figures are only guidelines, i.e., a depicted variant of the building impact protection device 1 can, for example, have a thickness of approx. 35-50 mm, a height of approx. 430 mm and a (standardized) length of approx. 1185 mm as well as a height of the hollow notch of approx. 54 mm.
