Technical Field
[0001] The present application relates to the technical field of high-frequency grounding layout, and in particular to a copper sheet layout structure of a metal plate house. Background Art
[0002] There are three main types of working ground signals generated by the transmitter and the overall broadcasting system of the transmitter in the room: first, safety grounding, whose grounding resistance cannot be greater than 4Ω; second, high-frequency grounding, whose grounding resistance cannot be greater than 1Ω; third, lightning protection grounding, whose grounding resistance cannot be greater than 10Ω. The walls of the metal plate room are directly connected to the safety grounding grid with flat iron. These three different groundings need to be connected to different grounding grids according to relevant national standards (GB), namely, lightning protection grounding grid, safety grounding grid and high-frequency grounding grid.
[0003] However, during work, comprehensive factors should be considered based on the actual grounding environment, soil conditions, and different construction environments. Safety grounding and lightning protection grounding are often connected to their respective grounding grids, and then merged into a unified grounding grid, while high-frequency grounding is laid separately.
[0004] Among them, for the computer rooms of some overseas institutions, because the construction period required is relatively short, some choose "color-coated steel glass wool sandwich insulation board" as the main material for building the walls of the computer room, and perform modular assembly on site, which shortens the construction period and saves construction costs.
[0005] Since the "color-coated steel glass wool sandwich insulation board" is a metal material, when laying the high-frequency grounding copper sheet, if the conventional grounding method is used to lay the high-frequency grounding copper sheet directly along the metal wall, the direct contact between the high-frequency grounding copper sheet and the metal wall will inevitably cause direct contact with the safety grounding signal and the lightning protection grounding signal, which will cause confusion or instability in the high-frequency signal system of the entire machine, and even cause reflection of the transmitter output signal, so further improvement is needed. Utility Model Content
[0006] In order to reduce the possibility of contact between high-frequency grounding copper and metal walls, the present application provides a copper layout structure for a metal plate house.
[0007] The present application provides a copper sheet layout structure for a metal plate house, which adopts the following technical solution:
[0008] A copper sheet layout structure for a metal sheet house comprises a copper sheet arranged along the height direction of a metal wall and a plurality of fixing components spaced apart along the length direction of the copper sheet, wherein the fixing components comprise a first fixing plate and a second fixing plate arranged on two opposite surfaces of the copper sheet and fixing parts for mounting the first fixing plate and the second fixing plate on the metal wall, wherein the first fixing plate and the second fixing plate are both made of insulating plates, and the second fixing plate abuts against the metal wall.
[0009] By adopting the above technical solution, the copper sheet is fixed to the metal wall through the first fixing plate, the second fixing plate and the fixing member. Since a plurality of fixing components are provided, the copper sheet and the metal wall are isolated to reduce direct contact between the two. Furthermore, the first fixing plate and the second fixing plate are both made of insulating plates, so that the high-frequency signal and the safety signal can be isolated to reduce the possibility of direct contact between these two different ground signals, thereby reducing the possibility of confusion or instability in the high-frequency signal system of the whole machine, and even the possibility of reflection of the transmitter output signal.
[0010] Preferably, a reinforcement portion for strengthening the connection between the first fixing plate and the second fixing plate is provided between the first fixing plate and the second fixing plate.
[0011] By adopting the above technical solution and providing a reinforcing portion, the fixing effect of the first fixing plate and the second fixing plate on the copper sheet is improved, so as to reduce the contact between the installed copper sheet and the metal wall as much as possible.
[0012] Preferably, the reinforcing portion includes a first convex strip arranged on the second fixing plate close to the copper surface, the length direction of the first convex strip is parallel to the length direction of the second fixing plate, and the surface of the first fixing plate close to the copper is provided with a first groove for the first convex strip to be embedded.
[0013] By adopting the above technical solution, through the cooperation between the first convex strip and the first groove, when the fixing piece installs the first fixing plate and the second fixing plate on the metal wall, the copper sheet is located as much as possible between the first convex strip and the first groove, so as to improve the installation of the copper sheet, limit the relative slip of the copper sheet, make it smoother, and reduce the possibility of relative slip between the first fixing plate and the second fixing plate when the fixing piece is installed, so as to reduce the difficulty of installation between the first fixing plate and the second fixing plate.
[0014] Preferably, the reinforcement portion further comprises a rack provided on the first convex strip, the length direction of the rack being parallel to the length direction of the first convex strip, a plurality of racks are provided at intervals along the width direction of the first convex strip, and tooth grooves are formed between adjacent racks.
[0015] By adopting the above technical solution, a plurality of racks are arranged on the first convex strip, so that when the first fixing plate and the second fixing plate are close to each other to squeeze the copper sheet, the friction between the first fixing plate and the copper sheet can be increased, so as to reduce the possibility of relative slippage between the first fixing plate and the second fixing plate, and the copper sheet can be made relatively straight, so as to improve the fixing effect of the fixing component on the copper sheet and reduce the contact with the metal wall.
[0016] Preferably, the fixing part is a fixing bolt, the metal wall is provided with a threaded hole for threaded connection of the fixing bolt, the first fixing plate and the second fixing plate are both penetrated with a through hole for the fixing bolt to pass through, and the through holes are provided at both ends of the first fixing plate and the second fixing plate.
[0017] By adopting the above technical solution, the fixing bolt is passed through two oppositely arranged through holes and then threadedly connected with the threaded hole to fix the position of the copper sheet.
[0018] Preferably, a second convex strip protrudes from one end of the second fixing plate, the length direction of the second convex strip is parallel to the length direction of the second fixing plate, the second convex strip is arranged close to the opposite side walls of the second fixing plate, the second convex strip is arranged away from the copper sheet, and the first fixing plate is provided with a second groove for the second convex strip to be embedded.
[0019] By adopting the above technical solution, when the fixing bolts are inserted through the holes and fixed to the metal wall, a drill is usually used to speed up the installation speed and installation strength. Therefore, in the process of installing the fixing bolts on the metal wall by the drill, the first fixing plate and the second fixing plate may be subjected to a force, and relative slippage may occur in the height direction. Therefore, the possibility of relative slippage between the first fixing plate and the second fixing plate is reduced by the cooperation between the second convex strip and the second groove. And the cooperation between the first convex strip and the first groove can also limit the possibility of relative slippage between the first fixing plate and the second fixing plate perpendicular to the height direction.
[0020] Preferably, the end surfaces of the two second convex strips away from the second fixing plate are both provided with guide surfaces, and the guide surfaces extend to the side walls of the two second convex strips close to each other.
[0021] By adopting the above technical solution, the guide surface is provided to facilitate the connection between the second convex strip and the second groove, thereby accelerating the installation speed.
[0022] Preferably, two of the second convex strips are protrudingly provided with protrusions, and the inner side wall of the second groove is provided with a slot for the protrusions to be engaged.
[0023] By adopting the above technical solution, a protrusion is provided, and a card groove is provided on the inner side wall of the second groove. Along with the guide surface, the second protrusion is slidably inserted into the second groove, and a certain force is applied to drive the protrusion to be embedded in the card groove, so that a certain fixation is performed between the first fixing plate and the second fixing plate. After a plurality of first fixing plates and second fixing plates are squeezed against the copper sheet, the fixing bolts are passed through the through holes and the metal wall to fix them, that is, the operations are performed separately, thereby speeding up the fixing efficiency of the copper sheet.
[0024] In summary, the utility model has the following beneficial effects:
[0025] 1. By providing a plurality of fixing components, the copper sheet and the metal wall are isolated to reduce direct contact between the two. Furthermore, the first fixing plate and the second fixing plate are both made of insulating plates, so that the high-frequency signal and the safety signal can be isolated to reduce the possibility of direct contact between these two different ground signals, thereby reducing the possibility of confusion or instability in the high-frequency signal system of the whole machine, and even the possibility of reflection of the transmitter output signal.

[0034] The following is combined with Figure 1-5 , further details of this application are given.
[0035] The embodiment of the present application discloses a copper sheet layout structure for a metal sheet house.
[0036] Embodiment 1:
[0037] A copper sheet layout structure for a metal plate house, with reference to the figure, comprises a copper sheet 2 arranged along the height direction of a metal wall 1 and a plurality of fixed components 3 spaced apart along the length direction of the copper sheet 2. In this embodiment, the metal wall 1 is specifically a color steel glass wool sandwich insulation board, and the floor connected to the metal wall 1 is an insulating floor, so the fixed components are specifically arranged on the metal wall. Among them, the length direction of the copper sheet 2 is parallel to the height direction of the metal wall 1, and the copper sheet 2 is specifically a red copper strip. Since the resistivity of red copper is 0.0154-0.0175Ω / m, it is a good material for high-frequency grounding, and the size of the copper sheet 2 is 100mm×0.45mm (width×thickness), and the spacing between adjacent fixed components 3 is 300mm-400mm.
[0038] Reference Figure 2 , Figure 3 , wherein the fixing assembly 3 specifically includes a first fixing plate 31 and a second fixing plate 32 arranged on two opposite surfaces of the copper sheet 2 and a fixing member 33 for installing the first fixing plate 31 and the second fixing plate 32 on the metal wall 1. In this embodiment, the first fixing plate 31 and the second fixing plate 32 are both made of insulating plates, specifically made of insulating bakelite, to isolate the copper sheet 2 from the metal wall 1, and the length direction of the first fixing plate 31 and the second fixing plate 32 is perpendicular to the length direction of the copper sheet 2.
[0039] A reinforcing portion 4 for reinforcing the connection with the copper sheet 2 is provided between the first fixing plate 31 and the second fixing plate 32. In this embodiment, the reinforcing portion 4 specifically includes a first convex strip 41 provided on the second fixing plate 32 close to the surface of the copper sheet 2 and a rack 42 provided on the first convex strip 41. The first convex strip 41 and the second fixing plate 32 are integrally formed, the length direction of the first convex strip 41 is parallel to the length direction of the second fixing plate 32, and the opposite side walls of the first convex strip 41 are flush with the opposite side walls of the second fixing plate 32. The length direction of the rack 42 is parallel to the length direction of the first convex strip 41, and a plurality of racks 42 are provided at intervals along the width direction of the first convex strip 41, and tooth grooves 43 are formed between adjacent racks 42.
[0040] Correspondingly, the lower surface of the first fixing plate 31 is provided with a first groove 311 for the first convex strip 41 to be inserted into, and the length direction of the first groove 311 is parallel to the length direction of the first fixing plate 31, and extends to the opposite side walls of the first fixing plate 31.

The second fixing plate 32 is away from the surface of the first fixing plate 31 and abuts against the metal wall 1.

The metal wall 1 is provided with a threaded hole for threaded connection of the fixing bolt (not shown in the figure). The first fixing plate 31 and the second fixing plate 32 are both penetrated by a through hole 5 for the fixing bolt to pass through. The through hole 5 is specifically arranged at both ends of the first fixing plate 31 and the second fixing plate 32, avoiding the first convex strip 41 and the first groove 311.
[0043] The implementation principle of the copper sheet 2 layout structure of a metal sheet house in the embodiment of the present application is as follows: the second fixing plate 32 is abutted against the metal wall 1, and then the copper sheet 2 is placed on the rack 42 on the second fixing plate 32, and then the first fixing plate 31 is pressed on the copper sheet 2, and after the through holes 5 on the first fixing plate 31 and the second fixing plate 32 are arranged correspondingly, the fixing bolts are threadedly connected through the through holes 5 and the threaded holes on the metal wall 1 by a drill bit to fix the copper sheet 2 on the metal wall 1, and isolate the copper sheet 2 from the metal wall 1 to reduce direct contact between the two. The high-frequency signal and the safety signal can be isolated to reduce the possibility of direct contact between these two different ground signals, thereby reducing the possibility of confusion or instability in the high-frequency signal system of the whole machine, and even the possibility of reflection of the transmitter output signal.

Therefore, in the present embodiment, a second convex strip 6 is protruded from one end of the second fixing plate 32, the length direction of the second convex strip 6 is parallel to the length direction of the second fixing plate 32, the second convex strip 6 is arranged close to the opposite side walls of the second fixing plate 32, and the second convex strip 6 is arranged away from the copper sheet 2. Correspondingly, the first fixing plate 31 is provided with a second groove 7 for the second convex strip 6 to be inserted.
[0046] Furthermore, in order to facilitate the engagement between the second convex strips 6 and the second grooves 7, in this embodiment, the end surfaces of the two second convex strips 6 away from the second fixing plate 32 are provided with guide surfaces 61, and the guide surfaces 61 extend to the side walls of the two second convex strips 6 close to each other. In addition, the two second convex strips 6 are provided with protrusions 62, and the inner side walls of the second grooves 7 are provided with grooves 71 for the protrusions 62 to engage, so as to improve the fixing effect between the upper fixing plate and the lower fixing plate, thereby accelerating the fixing efficiency of the copper sheet 2.
