Description

Technical Field

[0001] This invention relates to the field of building structure technology, and in particular to a lightning protection down conductor fixing structure, system, method, and exterior wall structure. Background Technology

[0002] In a building's lightning protection system, the lightning down conductor is a crucial conductive component that connects the lightning arrester and the grounding device, safely discharging the lightning current to the ground. Its installation reliability, durability, and maintainability directly affect the effectiveness of the entire lightning protection system and the building's safety.

[0003] Traditional building exterior walls are mostly solid concrete structures, and lightning protection down conductors are typically fixed directly to the exterior walls using methods such as pre-embedded installation, expansion bolts, or clamps. However, with increasing demands for building energy efficiency, a large number of industrial and civil buildings widely adopt external wall insulation systems. These systems typically consist of a frame (or supporting structure), insulation boards, and an outer protective layer, forming a composite wall with the exterior wall structure in a "sandwich" configuration. Fixing lightning protection down conductors to this "sandwich" structure using traditional methods presents serious technical drawbacks, especially in applications with extreme safety and maintainability requirements, such as nuclear power plants. These drawbacks are mainly manifested in the following ways: 1. Mismatch between structure and force: When the fasteners are directly fixed to the insulation board with low strength, the fastening force and the electromagnetic force of lightning current can easily cause the insulation board to crush and crack, damaging the integrity of the insulation system. In addition, the load on the fasteners cannot be effectively transferred to the main load-bearing structure of the exterior wall.

[0004] 2. Failure to meet the requirements of "visibility, inspection, and maintainability": Traditional concealed or non-removable fixing methods fix the down conductor to the exterior wall, concealing the down conductor and fixing point inside the "mezzanine" structure, making it impossible to inspect directly during operation and maintenance. Repair and replacement must damage the insulation layer and even the wall structure, resulting in high construction costs and long construction periods. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art by providing a lightning protection down conductor fixing structure, system, method and external wall structure that can fix the lightning protection down conductor to the supporting structure of the external wall and facilitate the inspection and replacement of the lightning protection down conductor.

[0006] In a first aspect, embodiments of the present invention provide a lightning protection down conductor fixing structure, which includes a base and a clamp. The base is fixed to a support structure of an exterior wall and is located on the outer side of the exterior wall. The clamp is disposed on the base and is used to clamp and fix the lightning protection down conductor.

[0007] In some embodiments, the exterior wall includes an exterior wall body, and a keel and an insulation board sequentially disposed on the outer side of the exterior wall body. The base is fixed to the keel by a connector, which passes through the insulation board.

[0008] In some embodiments, the lightning protection down conductor fixing structure further includes a waterproof sealing structure. The waterproof sealing structure is disposed between the base and the insulation board.

[0009] In some embodiments, the clamp is detachably connected to the base.

[0010] In some embodiments, the base has a clamping surface on the side facing the lightning protection down conductor that is adapted to the outer wall of the lightning protection down conductor. After the clamp holds and clamps the lightning protection down conductor, it presses the lightning protection down conductor tightly into the clamping surface.

[0011] In some embodiments, the clamping end of the clamp has two opposing elastic plates; the two elastic plates can move closer to each other through their own elastic deformation and move further apart under the action of external force, so as to hold or release the lightning protection down conductor.

[0012] In some embodiments, the elastic sheet is provided with a disassembly hole for operation by an external tool; the external tool can move the elastic sheet through the disassembly hole to move the two elastic sheets away from each other and release the lightning protection down conductor.

[0013] Therefore, the lightning protection down conductor fixing structure provided in this embodiment of the invention, by setting a base and a clamp, fixes the base to the supporting structure of the outer wall and positions it on the outer side of the outer wall. The clamp is set on the base to hold and fix the lightning protection down conductor. This can fix the lightning protection down conductor and transfer the load on the base, which bears the force of the lightning protection down conductor and the clamp, to the supporting structure of the outer wall, thereby improving the overall stability of the lightning protection down conductor fixing structure and thus improving the support stability of the lightning protection down conductor. Compared with the prior art where the fastener is directly fixed to the insulation board, it can avoid damaging the integrity of the insulation system, such as the insulation board. Furthermore, the above arrangement allows the lightning protection down conductor, clamp, and base to all be located on the outer side of the outer wall. Compared with the prior art where the lightning protection down conductor is fixed inside the "mezzanine" structure of the outer wall, it facilitates the inspection and maintenance of the lightning protection down conductor, clamp, and base. Moreover, when inspecting and replacing the lightning protection down conductor fixing structure, it is not necessary to damage the insulation board and the outer wall structure, thus improving the convenience of construction.

[0014] Secondly, embodiments of the present invention also provide a lightning protection down conductor fixing system, which includes multiple sets of lightning protection down conductor fixing structures as described in the first aspect, wherein the multiple sets of lightning protection down conductor fixing structures are arranged at intervals along the extension direction of the lightning protection down conductor.

[0015] Thirdly, embodiments of the present invention also provide an external wall structure, which includes an external wall and the lightning protection down conductor fixing structure mentioned in the first aspect.

[0016] Fourthly, embodiments of the present invention also provide a method for fixing a lightning protection down conductor. The method for fixing a lightning protection down conductor uses the lightning protection down conductor fixing structure in the first aspect. The method for fixing a lightning protection down conductor includes: installing a clamp on a base, fixing the assembled base to a support structure of an outer wall, and positioning the base on the outside of the outer wall; and clamping and fixing the lightning protection down conductor using the clamp.

[0017] The above-described lightning protection down conductor fixing system, external wall structure, and lightning protection down conductor fixing method have the same beneficial technical effects as the lightning protection down conductor fixing structure provided in some of the above embodiments, and will not be repeated here.

[0021] The technical solutions in some embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art are within the scope of protection of the present invention.

[0022] Where there is no conflict, the various embodiments of the present invention and the features thereof may be combined with each other.

[0023] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.

[0024] Unless the context otherwise requires, throughout the specification and claims, the term "comprising" is interpreted as open-ended and encompassing, meaning "including, but not limited to." Furthermore, the specific features, structures, materials, or characteristics described may be included in any suitable manner in any one or more embodiments or examples.

[0025] In describing some embodiments, the term "connection" and its derivative expressions may be used. The term "connection" should be interpreted broadly; for example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. The embodiments of the invention described herein are not necessarily limited to the content of this document.

[0026] This document describes exemplary embodiments with reference to cross-sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and the area of ​​regions are enlarged for clarity. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the areas of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0027] Example 1: like Figure 1 As shown in the figure, this embodiment of the invention provides a lightning protection down conductor fixing structure, which is applied in building lightning protection engineering to fix the lightning protection down conductor.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the lightning protection down conductor fixing structure includes a base 6 and a clamp 5. The base 6 is fixed to the supporting structure of the exterior wall and is located on the outside of the exterior wall. The clamp 5 is mounted on the base 6 and is used to clamp and fix the lightning protection down conductor 4.

[0029] The supporting structure of the exterior wall can be any structure that provides support within the exterior wall structure.

[0030] For example, the aforementioned exterior wall can be the exterior wall of the nuclear island, the exterior wall of the conventional island, or the exterior wall of a civil building.

[0031] In some examples, such as Figure 1 As shown, the exterior wall includes an exterior wall body 3, and a keel 2 and an insulation board 1 arranged sequentially on the outside of the exterior wall body 3.

[0032] At this point, the supporting structure for the exterior wall can be the keel 2. The base 6 is fixed to the keel 2 and located on the outside of the insulation board 1.

[0033] In some examples, the base 6 is fixed to the keel 2 by a connector 7 that passes through the insulation board 1.

[0034] For example, the base 6 can be U-shaped, and the connector 7 can be a self-tapping screw. The self-tapping screw passes through the waist of the base 6, passes through the insulation board 1, and is fixed to the keel 2. It is understood that the waist of the base 6 and the insulation board 1 are provided with mounting holes for the connector 7 to pass through.

[0035] Through the above configuration, the load on the base 6 (the force bearing the lightning conductor 4 and the clamp 5) can be transferred to the supporting structure of the exterior wall, improving the overall stability of the lightning conductor fixing structure and thus enhancing the support stability of the lightning conductor 4. Compared to the prior art where the lightning conductor fixing components are directly fixed to the insulation board, this avoids damaging the integrity of the exterior wall insulation system (e.g., insulation board 1). Furthermore, with the above configuration, the lightning conductor 4, clamp 5, and base 6 are all located on the outside of the exterior wall. Compared to the prior art where the lightning conductor is fixed inside the "mezzanine" structure of the exterior wall, this facilitates the inspection and maintenance of the lightning conductor 4, clamp 5, and base 6. When inspecting or replacing the lightning conductor fixing structure, it is not necessary to damage the insulation board 1 or the exterior wall structure, thus improving construction convenience.

[0036] Therefore, the lightning protection down conductor fixing structure provided in this embodiment of the invention, by setting a base 6 and a clamp 5, fixes the base 6 to the supporting structure of the outer wall and positions it on the outer side of the outer wall, and sets the clamp 5 on the base 6 to clamp and fix the lightning protection down conductor 4. This can fix the lightning protection down conductor 4 and transfer the load on the base 6 (the force bearing the lightning protection down conductor 4 and the clamp 5) to the supporting structure of the outer wall, improving the overall stability of the lightning protection down conductor fixing structure, and thus improving the support stability of the lightning protection down conductor 4. Compared with the prior art of directly fixing the fastener to the insulation board, this can avoid damaging the integrity of the insulation system (e.g., insulation board 1). Furthermore, the above-mentioned arrangement allows the lightning protection down conductor 4, clamp 5, and base 6 to be located on the outside of the exterior wall. Compared with the prior art where the lightning protection down conductor is fixed inside the "mezzanine" structure of the exterior wall, it is easier to inspect and maintain the lightning protection down conductor 4, clamp 5, and base 6. Moreover, when inspecting and replacing the lightning protection down conductor fixing structure, it is not necessary to damage the insulation board 1 and the exterior wall structure, thus improving the convenience of construction.

[0037] In some examples, where the aforementioned outer wall is the outer wall of the nuclear island, the connector 7, clamp 5, and base 6 are all made of stainless steel.

[0038] In some embodiments, such as Figure 1 As shown, the lightning protection down conductor fixing structure also includes a waterproof sealing structure 8. The waterproof sealing structure 8 is disposed between the base 6 and the insulation board 1.

[0039] For example, the waterproof sealing structure 8 can be a waterproof sealing ring.

[0040] The aforementioned connector 7 (self-tapping screw) passes through the waist of the base 6, the waterproof sealing ring, and the insulation board 1 in sequence before being fixed to the keel 2.

[0041] The above settings can improve the waterproof performance between the base 6 and the insulation board 1, prevent external moisture from seeping into the interior of the insulation board 1 through the lightning protection down conductor fixing structure, and thus prevent corrosion of the equipment inside the exterior wall.

[0042] In some embodiments, the clamp 5 is detachably connected to the base 6.

[0043] For example, the clamp 5 and the base 6 are detachably connected by plugging or snapping.

[0044] For example, the base 6 is provided with a slot or a bayonet, and the clamp 5 is inserted into the slot or snapped into the bayonet.

[0045] With the above setup, the clamp 5 can be quickly installed on the base 6 and removed from the base 6, thus facilitating the installation and replacement of the clamp 5.

[0046] In some embodiments, combined with Figure 2 and Figure 3 The base 6, facing the side of the lightning protection down conductor 4, has a clamping surface that fits the outer wall of the lightning protection down conductor 4. After the clamp 5 clamps and holds the lightning protection down conductor 4, it presses the lightning protection down conductor 4 tightly into the clamping surface.

[0047] like Figure 2 and Figure 3 As shown, the base 6 is U-shaped. After the clamp 5 is installed on the base 6, the clamping end of the clamp 5 extends to the outside of the two side plates of the base 6. The outside of the two side plates of the base 6 is provided with a semi-circular receiving groove, and the groove wall of the receiving groove forms the above-mentioned clamping surface.

[0048] Combination Figure 1 After clamping the lightning protection down conductor 4, the side of the lightning protection down conductor 4 is pressed into the clamping surface, so that the contact between the lightning protection down conductor 4 and the base 6 is surface contact, reducing the pressure between the lightning protection down conductor 4 and the base 6, thereby avoiding the base 6 from causing indentation, deformation or plating damage to the lightning protection down conductor 4.

[0049] In some embodiments, such as Figure 2 and Figure 3 As shown, the clamping end of the clamp 5 has two elastic plates arranged opposite each other; the two elastic plates can approach each other through their own elastic deformation and move away from each other under the action of external force, so as to hold or release the lightning protection down conductor 4.

[0050] For example, the clamp 5 can be a U-shaped stainless steel sheet. After the U-shaped stainless steel sheet is inserted into the base 6, it is snapped onto the base 6. The two ends of the U-shaped stainless steel sheet are located on the outside of the base 6, forming the clamping ends of the clamp 5.

[0051] like Figure 3 As shown, the clamping ends of the clamp 5 are all bent inward to fit the size of the lightning protection down conductor 4, so that the clamping ends of the clamp 5 can clamp the lightning protection down conductor 4.

[0052] With the above-described configuration, the lightning protection down conductor 4 can be clamped by two relatively positioned elastic plates under their own elastic force, and it is easy to loosen the lightning protection down conductor 4 by external force.

[0053] In some embodiments, such as Figure 1 and Figure 2 As shown, the elastic sheet has a disassembly hole 9 for external tools to operate; the external tool can move the elastic sheet through the disassembly hole 9 to make the two elastic sheets move away from each other and release the lightning protection down conductor 4.

[0054] For example, the external tool can be a pry bar, and the size of the disassembly hole 9 is larger than the cross-sectional size of the pry bar.

[0055] Combination Figure 1 and Figure 2 An external tool is inserted through the disassembly hole 9 between the two elastic plates and applies a force to one of the elastic plates away from the other, thereby loosening the two elastic plates and allowing the lightning protection down conductor 4 to be easily removed from the clamp 5 for replacement. Therefore, when disassembling and maintaining the lightning protection down conductor 4, it is only necessary to pull the lightning protection down conductor 4 out of the clamp 5 through the disassembly hole 9. The entire process does not touch or damage the foundation connection between the insulation board 1 and the keel 2, realizing non-destructive construction and maintenance of the lightning protection down conductor 4.

[0056] In summary, the lightning protection down conductor fixing system provided by the embodiments of the present invention has the following advantages: 1. The split structure of clamp 5 and base 6 enables quick installation and non-destructive disassembly of the lightning protection down conductor fixing structure, facilitating the maintenance of the lightning protection down conductor fixing structure; 2. By rigidly connecting the base 6 and the keel 2, the force transmission path of the lightning protection down conductor 4 is reconstructed, and the load of the lightning protection down conductor 4 is directly transmitted to the main structure (the keel 2 of the exterior wall), avoiding damage to the exterior wall insulation system caused by fixing it to the exterior wall insulation system as in the existing technology. 3. The lightning protection down conductor 4 is clamped without damage by the elastic clamp 5 and the base 6 with the clamping surface, which protects the conductive section and anti-corrosion layer of the lightning protection down conductor 4 and ensures that lightning is smoothly discharged through the lightning protection down conductor 4. 4. The exposed design of the clamps 5 and the base 6, along with the stainless steel material, ensures that the entire lightning protection down conductor fixing structure is visible, inspectable, and waterproof for a long time, which is in line with the nuclear safety "defense in depth" concept.

[0057] Example 2: This invention also provides a lightning protection down conductor fixing system, which is applied in lightning protection buildings. The lightning protection down conductor fixing system includes multiple sets of lightning protection down conductor fixing structures as described in Embodiment 1. The multiple sets of lightning protection down conductor fixing structures are arranged at intervals along the extension direction of the lightning protection down conductor 4.

[0058] With the above settings, the lightning protection down conductor 4 can be fixed simultaneously by multiple sets of lightning protection down conductor fixing structures, thereby improving the fixing strength and stability of the lightning protection down conductor 4.

[0059] Example 3: This invention also provides an external wall structure, which includes an external wall and the lightning protection down conductor fixing structure in Embodiment 1.

[0060] For example, the exterior wall can be the nuclear island exterior wall, which includes an external wall insulation system.

[0061] With the above settings, the lightning protection down conductor 4 can be fixed to the external wall structure through the lightning protection down conductor fixing structure, thereby improving the stability of the lightning protection down conductor 4 fixed on the external wall and facilitating the inspection and replacement of the lightning protection down conductor 4 on the external wall.

[0062] Example 4: This invention also provides a method for fixing a lightning protection down conductor. The method uses the lightning protection down conductor fixing structure in Embodiment 1. The method includes: installing a clamp 5 on a base 6 and fixing the assembled base 6 to the support structure of the outer wall, with the base 6 located on the outside of the outer wall; and clamping and fixing the lightning protection down conductor 4 with the clamp 5.

[0063] Using the above method, the lightning protection down conductor 4 can be clamped and fixed by the clamp 5, and the load on the base 6 (bearing the force of the lightning protection down conductor 4 and the clamp 5) can be transferred to the supporting structure of the outer wall, improving the overall stability of the lightning protection down conductor fixing structure, and thus improving the supporting stability of the lightning protection down conductor 4. Compared with the prior art of directly fixing the fixing parts of the lightning protection down conductor 4 to the insulation board, the integrity of the insulation board can be avoided. Using the above method, the lightning protection down conductor 4 can also be fixed to the outside of the outer wall by the clamp 5. Compared with the prior art of fixing the lightning protection down conductor inside the "mezzanine" structure of the outer wall, it is easier to inspect and maintain the lightning protection down conductor 4, the clamp 5, and the base 6. Moreover, when inspecting and replacing the lightning protection down conductor fixing structure, there is no need to damage the insulation board and the outer wall structure, which improves the convenience of construction.

[0064] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
