Description

Technical Field

[0001] This utility model relates to the field of building protection structure technology, specifically to a concrete protection structure that resists electromagnetic interference. Background Technology

[0002] In the installation environment of electromagnetically sensitive equipment, external electromagnetic interference (such as radio waves and electromagnetic pulses) can seriously affect the normal operation of the equipment. Therefore, it is necessary to block the propagation of electromagnetic signals through protective structures. Existing concrete protective structures mostly achieve electromagnetic interference resistance by incorporating metal fibers into the concrete or laying a single layer of metal mesh.

[0003] However, due to the uneven distribution of metal materials, gaps that can easily lead to electromagnetic signal leakage are easily formed, especially at wall corners and joints. The metal mesh may not overlap tightly or the metal fibers may not disperse well, resulting in a significant decrease in electromagnetic shielding effectiveness. This makes it impossible to meet the stringent requirements of highly sensitive equipment for the electromagnetic environment. Strong external electromagnetic signals can still penetrate through the gaps and interfere with the operating accuracy of the equipment. Therefore, an electromagnetic interference-resistant concrete protective structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a concrete protective structure for electromagnetic interference resistance, solving the problem in the prior art where uneven distribution of metal materials easily leads to gaps that allow electromagnetic signal leakage, especially at wall corners and joints where the metal mesh is not tightly overlapped or the metal fibers are poorly dispersed, resulting in a significant decrease in electromagnetic shielding effectiveness and failing to meet the stringent requirements of highly sensitive equipment for the electromagnetic environment. Strong external electromagnetic signals can still penetrate through the gaps, interfering with the operational accuracy of the equipment.

[0005] This utility model provides the following technical solution: an anti-electromagnetic interference concrete protective structure, comprising several concrete substrates, each of which is provided with an anti-electromagnetic interference component inside, each of which has an insertion port on its left side end and an insertion plate fixedly connected to its right side end.

[0006] As a preferred embodiment of the above technical solution, the anti-electromagnetic interference component includes several metal shielding meshes, each of which is embedded in a concrete matrix, and an isolation layer is provided between every two metal shielding meshes.

[0007] As a preferred embodiment of the above technical solution, the metal shielding mesh includes several metal wires one and several metal wires two, which are fixedly connected to each other.

[0008] As a preferred embodiment of the above technical solution, the plurality of metal wires one and the plurality of metal wires two are arranged in a crisscross pattern.

[0009] As a preferred embodiment of the above technical solution, the side end of the concrete substrate is provided with a plurality of screw holes one, and the side end of the insert plate is provided with a plurality of screw holes two, and fasteners are provided between the plurality of screw holes one and the plurality of screw holes two.

[0010] As a preferred embodiment of the above technical solution, the fastener includes a screw rod, which is threaded between screw hole one and screw hole two, and a rotating head is fixedly connected to the side end of the screw rod.

[0011] As a preferred embodiment of the above technical solution, a metal pressure plate is fixedly connected to the inner side of the socket, and conductive sealant is fixedly connected to the side end of the metal pressure plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention forms a three-dimensional shielding barrier through a multi-layered, crisscrossed metal shielding mesh. The seamless overlap of the metal pressure plates and conductive sealant at the insertion ports and plates improves electromagnetic shielding effectiveness and effectively blocks electromagnetic signals propagating through gaps. The cross-laying of the metal mesh combined with soldering fixation reduces mesh deformation, and the glass fiber reinforced concrete matrix reduces the risk of cracking, ensuring that the shielding assembly remains intact during long-term use.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1-4As shown, this utility model provides a technical solution: an anti-electromagnetic interference concrete protective structure, comprising several concrete substrates 1. The concrete substrates 1 are made of fine stone concrete and have glass fibers evenly distributed inside to enhance the crack resistance of the substrate and prevent damage to the shielding layer due to substrate cracking. Each concrete substrate 1 is equipped with an anti-electromagnetic interference component 4. Each concrete substrate 1 has an insertion port 101 on its left side and an insertion plate 102 fixedly connected to its right side. Through the coordinated arrangement of the anti-electromagnetic interference component 4, the insertion plate 102, and the insertion port 101, the problem of electromagnetic signal leakage caused by uneven distribution of metal materials is solved. This is especially true at wall corners and joints, where the metal mesh is not tightly overlapped or the metal fibers are poorly dispersed, resulting in a significant decrease in electromagnetic shielding effectiveness. This fails to meet the stringent requirements of highly sensitive equipment for the electromagnetic environment, and strong external electromagnetic signals can still penetrate through the gaps, interfering with the operating accuracy of the equipment.

[0017] As one implementation method in this embodiment, such as Figure 4 As shown, the anti-electromagnetic interference component 4 includes several metal shielding meshes 401, all of which are embedded in the concrete substrate 1. Each metal shielding mesh 401 includes several metal wires 402 and several metal wires 403, which are fixedly connected and arranged in a crisscross pattern. An isolation layer 404 is provided between every two metal shielding meshes 401. In practice, the metal shielding meshes 401 are made of copper, and the intersections of the warp and weft threads of each layer are fixed by soldering to form a stable conductive whole. The laying directions of adjacent metal meshes are arranged in a crisscross pattern to reduce the possibility of signals directly passing through the mesh. The isolation layer 404 is a polytetrafluoroethylene film, which is laid between the two metal meshes to avoid electrochemical corrosion caused by contact between different metals and to force the electromagnetic signal to be reflected and attenuated multiple times between the multiple meshes through its insulation properties.

[0018] As one implementation method in this embodiment, such as Figure 2 and Figure 3As shown, the side end of the concrete substrate 1 has several screw holes 103, and the side end of the insert plate 102 has several screw holes 104. Fasteners 3 are provided between the screw holes 103 and 104. Each fastener 3 includes a screw 301, which is threaded between the screw holes 103 and 104. A rotating head 302 is fixedly connected to the side end of the screw 301. A metal pressure plate 2 is fixedly connected to the inner side of the insertion port 101, and conductive sealant 201 is fixedly connected to the side end of the metal pressure plate 2. In practice, by inserting the insert plate 102 into the insertion port 101, the conductive sealant 201 and the metal pressure plate 2 achieve a sealed connection between the insert plate 102 and the insertion port 101, preventing moisture from entering. The fastener 3 is installed by threading the screw 301 into the screw hole 103 and screw hole 104, and then using conductive sealant 201 to fix the two sets of concrete substrates 1, which facilitates the assembly of concrete substrates 1. The metal pressure plate 2 is made of thick brass plate, and its inner side is attached to the overlapping edge of the metal shielding mesh 401. It is fastened by stainless steel fastener 3 (copper plated), so that the overlapping edges of adjacent metal shielding meshes 401 are in close contact. The conductive sealant 201 is a silver-based conductive paste, which is applied between the overlapping edge and the metal pressure plate 2 and around the head of the fastener 3 to fill the gap and enhance conductivity. After curing, it forms an elastic sealing layer, which can prevent moisture from entering and causing the shielding mesh to rust, and further block the propagation path of electromagnetic signals through the gap.

[0019] Working principle: By inserting the insert plate 102 into the socket 101, the conductive sealant 201 and the metal pressure plate 2 achieve a sealed connection between the insert plate 102 and the socket 101, preventing moisture from entering. The fastener 3 connects the screw 301 threaded between screw hole 103 and screw hole 104, and with the use of conductive sealant 201, the two sets of concrete substrates 1 are fixedly connected, facilitating the assembly of the concrete substrates 1. After assembly, because the metal shielding mesh 401 is made of copper, the intersections of the warp and weft threads of each layer are fixed by soldering, forming a stable conductive whole. The laying directions of adjacent metal mesh layers are crisscrossed to reduce signal transmission through the mesh. To prevent direct electromagnetic interference, the insulating layer 404, made of polytetrafluoroethylene film, is laid between two layers of metal mesh. This avoids electrochemical corrosion caused by contact between different metals and forces electromagnetic signals to attenuate through multiple reflections between the layers of mesh via its insulating properties. Thus, the multi-layered, crisscrossed metal shielding mesh 401 forms a three-dimensional shielding barrier. Combined with the seamless overlap of the metal pressure plate 2 and conductive sealant 201 at the socket 101 and the insertion plate 102, the electromagnetic shielding effectiveness is improved, effectively blocking electromagnetic signals propagating through gaps. The cross-laying of the metal mesh, along with the soldering fixation, reduces mesh deformation, and the glass fiber reinforced concrete matrix 1 reduces the risk of cracking, ensuring that the shielding assembly remains intact during long-term use.

[0020] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
