Description

Technical Field

[0001] This invention relates to the field of lightning protection technology for ancient buildings, specifically to an integrated lightning protection structure and installation method for lightning arresters on the roof of ancient buildings. Background Technology

[0002] Lightning protection construction is an important part of the restoration of ancient buildings. It requires combining traditional construction techniques with the principles of "restoring the old as it was" and "minimal intervention". The design and construction should adopt different solutions according to the specific conditions of the building. The lightning protection device must be integrated with the building and the overall appearance requirements are strict.

[0003] In existing engineering examples, lightning protection for ancient buildings often involves laying round steel lightning rods along the roof ridge. However, this exposed approach severely damages the beautiful outline and historical features of ancient buildings, significantly impacting their appearance and resulting in a poor overall aesthetic. Furthermore, since most ancient buildings feature sloping or pointed roofs, the lightning rods are often secured with clamps, which are prone to loosening under long-term wind, rain, and vibration. This leads to insecure fixing of the lightning rods, unreliable electrical connections, and potential safety hazards.

[0004] Therefore, there is an urgent need for a new lightning protection technology solution that can meet the requirements of lightning protection technology, preserve the original appearance of ancient buildings to the greatest extent, and be firmly installed and easy to maintain. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated lightning protection structure and installation method for lightning arresters on the roof of ancient buildings.

[0013] In some embodiments, the concealed structure further includes a plurality of constraint pieces, which are arranged in a ring on the bottom plate of the guide ring, and the concealed lead wire is held between the plurality of constraint pieces.

[0014] A method for installing an integrated lightning protection structure for the roof of an ancient building includes the following steps: Step S1: Data Acquisition; The appearance, shape, size parameters, and material of the original ridge tiles of the ancient building were obtained through measurement. Step S2: Lightning strike simulation; The obtained parameters are input into the corresponding simulation software, and multiple lightning strike simulation tests are conducted. Through data analysis, the lightning-prone points on the roof of the ancient building are obtained. Step S3: Install the lightning rod and lightning protection net; A lightning rod is installed at the top center of the ancient building. The original ridge tile corresponding to the lightning-prone point on the roof of the ancient building is removed, and a lightning-blocking unit is installed at that location, so that multiple lightning-blocking units form a lightning-blocking mesh on the roof of the ancient building. Step S4: Integrated installation of the lightning arrester; A concealed down conductor is installed on the side of the ancient building, with the bottom of the concealed down conductor connected to the grounding device and the top of the concealed down conductor connected to the lightning rod and multiple lightning receiving units.

[0016] The above-described technical solutions in the embodiments of the present invention have at least the following technical effects or advantages: (1) The appearance, size and material of the lightning-blocking ridge tile of the present invention are completely consistent with the original ridge tile. It is seamlessly connected with the surrounding original ridge tile through overlapping installation. The lightning-blocking plate and lightning-blocking line are hidden in the ridge tile structure and do not protrude from the roof surface, so that the lightning-blocking net and the roof ridge tile are integrated, which completely solves the problem of the traditional exposed lightning-blocking device destroying the appearance of ancient buildings. At the same time, the hidden structure completely hides the concealed down conductor in the guide cover. The guide cover uses the same material and decoration as the wall, realizing the integration of the concealed down conductor with the wall, and visually completely preserving the ancient appearance of the ancient building.

[0017] (2) The present invention uses a composite lightning protection structure of lightning rod and lightning net. The lightning rod shell covers the central area of ​​the roof, and the lightning net is composed of multiple lightning protection units arranged along the main ridge and secondary ridge to accurately cover the roof's lightning-prone points. The protection range of the two complements each other and effectively intercepts lightning leaders from different directions and heights, thereby achieving a roof lightning protection without dead angles.

[0018] (3) Before installation, the parameters of the roof of the ancient building are collected by measurement and combined with lightning strike simulation software to accurately locate the points prone to lightning strike. Only the original ridge tiles at the points prone to lightning strike need to be replaced, and there is no need to make large-scale modifications to the roof. After installation, the ridge tiles and the original ridge tiles, the guide cover and the wall are seamlessly connected, no additional repair is required, secondary damage is avoided, and damage to the ancient building is minimized.

[0026] refer to Figure 1-6An integrated lightning protection structure for the roof of an ancient building includes a lightning rod 1, a concealed down conductor 3, a grounding device 4, and a lightning protection network 5. The lightning rod 1, which may be made of copper, is vertically installed at the intersection of the roof ridge and the roof beams of the ancient building. Its bottom is fixedly connected to the wooden beams or concrete base of the roof via a flange. An insulating gasket is placed between the flange and the base to prevent direct electrical conduction between the lightning rod 1 and the roof structure, thus avoiding localized damage. The top of the lightning rod 1 is conical with a cone angle of 30-45° to improve the interception efficiency of lightning leaders. Its height is determined according to the roof height of the ancient building 2, ensuring that the protection range of the lightning rod 1 covers the central area of ​​the roof, forming a complementary coverage with the lightning protection network. The roof of the ancient building 2 is covered with multiple original ridge tiles 21, which are laid using a stacking process to form a complete roof ridge tile structure. The concealed down conductor 3 can be made of multi-strand copper stranded wire with a cross-sectional area of ​​not less than 25mm², possessing good conductivity and flexibility, and can adapt to slight deformation of the wall. The concealed down conductor 3 is buried in concealed locations where the gable wall and roof of the ancient building 2 intersect, such as the brick joints inside the eaves and wall cavities, to avoid exposing the down conductor 3 and damaging the appearance of the ancient building 2. The upper end of the concealed down conductor 3 can be fixed to the flange at the bottom of the lightning rod 1 by bolt connection. The connection is tin-plated to reduce contact resistance and form the main path for lightning energy conduction. The lower end... The grounding device 4 is welded and fixed with a welding length of not less than 100mm and wrapped with anti-corrosion coating to prevent corrosion failure. The grounding device 4 can be composed of a ring grounding body and a vertical grounding electrode. The ring grounding body can be made of 40×4mm flat copper and laid around the outside of the foundation of the ancient building. The vertical grounding electrode can be made of 20mm diameter copper rods, evenly arranged along the ring grounding body and driven vertically into the ground. The top is welded and fixed to the ring grounding body. This can quickly conduct the lightning energy conducted by the concealed down conductor 3 into the ground and complete the discharge of lightning energy. The lightning protection net 5 is laid on the roof of the ancient building 2, covering the main and secondary ridges and areas prone to lightning strikes. It is integrally formed with the roof of the ancient building 2 and is reliably connected to the concealed down conductor 3. It forms a complementary lightning protection system with the lightning rod 1. While ensuring comprehensive lightning protection coverage and efficient discharge of lightning energy, it preserves the original appearance of the ancient building 2 to the maximum extent. It is stable in connection and has strong resistance to environmental interference. It is suitable for lightning protection renovation of various traditional ridge tile structure ancient buildings 2.

[0027] The lightning protection network 5 consists of multiple lightning protection units, which are arranged according to the distribution pattern of the roof ridge tiles. Each lightning protection unit corresponds to a lightning-prone point on the roof. The installation is achieved by replacing the original ridge tiles, seamlessly connecting with the surrounding original ridge tiles, and forming an integrated form with the roof ridge tile structure of the ancient building 2, forming a mesh-like covering structure. Furthermore, each lightning protection unit is electrically connected to the concealed down conductor 3, ensuring that lightning energy can be conducted to the down conductor through any lightning protection unit.

[0028] The lightning-catching unit includes a lightning-catching ridge tile 51, a reinforcing structure 52, and a lightning-catching line 53. The lightning-catching ridge tile 51 is the core lightning-catching component, located between two adjacent original ridge tiles 21. One end of the lightning-catching ridge tile 51 is pressed against the lower surface of the upper original ridge tile 21, and the other end is pressed and covered by the lower original ridge tile 21. Through overlapping and fitting, the lightning-catching ridge tile 51 and the two adjacent original ridge tiles 21 form a seamless integrated structure, maintaining the integrity of the roof appearance. The reinforcing structure 52 is assembled at the bottom of one end of the lightning-catching ridge tile 51, and the reinforcing structure... The original ridge tile 21 below is inserted and fixed between the lightning-absorbing ridge tile 52 and the lightning-absorbing ridge tile 51. This mechanical snap-fit ​​method strengthens the connection stability between the lightning-absorbing ridge tile 51 and the original ridge tile 21, resisting external interference such as strong winds and temperature deformation. The lightning-absorbing wire 53 can be made of copper stranded wire. The lightning-absorbing wire 53 is laid between the lightning-absorbing ridge tile 51 and the concealed down conductor 3. One end is electrically connected to the lightning-absorbing ridge tile 51, and the other end is welded to the concealed down conductor 3, achieving a continuous path between each lightning-absorbing unit and the concealed down conductor 3, forming a complete lightning-absorbing network. The connections between the lightning-absorbing wire 53 and the lightning-absorbing ridge tile 51 and the concealed down conductor 3 are all tin-plated, with a contact resistance of no more than 0.01Ω, ensuring smooth conduction of lightning energy.

[0029] In some embodiments, the lightning-absorbing ridge tile 51 includes a lightning-absorbing body 511, a lightning-absorbing groove 512, and a lightning-absorbing plate 513. The lightning-absorbing body 511 is completely identical in material, shape, and size to the original ridge tile 21, ensuring compatibility with the surrounding original ridge tiles 21. The lightning-absorbing body 511 is embedded between two original ridge tiles 21, with one end pressed against the lower surface of the upper original ridge tile 21 and the other end pressed against the lower original ridge tile 21, forming a superimposed structure. This is consistent with the original ridge tile laying method, achieving an integrated appearance to ensure compatibility and uniformity with the original ridge tiles on the roof, thereby reducing the impact of the lightning-absorbing structure on the roof appearance and preserving the ancient building to the greatest extent. The original appearance of Building 2 is maintained. The lightning trough 512 is located at the top center of the lightning receiving body 511. It can be arc-shaped and can provide an installation carrier for the lightning receiving plate 513. The lightning receiving plate 513 can be made of pure copper and its width matches that of the lightning receiving trough 512. The lightning receiving plate 513 is embedded in the lightning receiving trough 512 and welded to the lightning receiving wire 53. It is the core conductive component of the lightning ridge tile 51. Multiple lightning rods 514 are vertically arranged on the top of the lightning receiving plate 513 and evenly distributed along the length of the lightning receiving plate. The top of the lightning rods 514 is 3-5mm higher than the top of the lightning receiving body 511. They can actively intercept lightning leaders and improve lightning reception efficiency.

[0030] In some embodiments, the thickness of the lightning-absorbing plate 513 is greater than the depth of the lightning-absorbing groove 512, but less than the sum of the depth of the lightning-absorbing groove 512 and the thickness of the original ridge tile 21. This dimension allows the lightning-absorbing plate 513 to be positioned and fixed after installation by pressing its top end against the upper original ridge tile 21, preventing it from loosening and falling off. At the same time, it prevents the top of the lightning-absorbing body 511 from protruding from the surface of the upper original ridge tile 21 due to excessive thickness, thereby affecting the flow of water from the upper original ridge tile 21 to the lightning-absorbing ridge tile 51, ensuring smooth drainage and avoiding the corrosion of the lightning-absorbing ridge tile 51 caused by water squeezing.

[0031] In some embodiments, the lightning-blocking ridge tile 51 further includes a connecting half-ring 516. The connecting half-ring 516 may be made of copper and has a semi-circular structure. The connecting half-ring 516 is fixedly disposed on one side of the bottom of the lightning-blocking plate 513 and integrally formed with the lightning-blocking plate 513. The lightning-blocking wire 53 passes through the connecting half-ring 516 and is welded and fixed to the lightning-blocking plate 513, thereby strengthening the connection strength between the lightning-blocking wire 53 and the lightning-blocking plate 513 and facilitating the laying and positioning of the lightning-blocking wire 53.

[0032] In some embodiments, the lightning-absorbing ridge tile 51 further includes a cavity 515, which is formed inside the lightning plate 513 and has an arc-shaped structure. The bottom of the lightning rod 514 extends into the cavity 515 and contacts the heat-absorbing medium filled in the cavity. The heat-absorbing medium can be a mixture of expanded graphite and ceramic fiber, which can quickly absorb the instantaneous high temperature generated when lightning strikes, and prevent the lightning-absorbing body 511 and the surrounding original ridge tile 21 from cracking due to overheating.

[0033] In some embodiments, the reinforcing structure 52 includes a locking block 521, a locking groove 522, a slide rail 523, and a resetting member 524. The locking block 521 may be made of stainless steel and has an L-shaped structure. It is locked to the bottom of the original ridge tile 21 below, forming a firm connection with the original ridge tile 21. The locking groove 522 is opened at the corresponding position on the bottom of the lightning-absorbing body 511 and its size is adapted to the locking block 521, providing sliding space for the locking block 521. The slide rail 523 is fixedly disposed on the inner side wall of the locking groove 522 and extends along the length of the locking groove 522. The protruding part of the locking block 521 can be slidably disposed in the slide rail 523, allowing slight relative displacement between the lightning-absorbing ridge tile 51 and the original ridge tile 21 to adapt to environmental deformation. The resetting member 524 may be a compression spring, disposed between the top wall of the locking block 521 and the locking groove 522, and is in a pre-compressed state. It can apply continuous elastic pressure to ensure that the lightning-absorbing ridge tile 51 is always tightly fitted with the original ridge tile 21, thereby improving the anti-interference capability.

[0034] In some embodiments, the structure further includes a concealed structure 6, which includes a guide cover 61, multiple guide rings 62, and multiple connecting rods 63. The guide cover 61 can be made of brick or wood, the same material as the wall of the ancient building 2, and has a rectangular plate-like structure. Its height is the same as the arrangement height of the concealed down conductor 3. The guide cover 61 is vertically fixed to the side wall of the ancient building, flush with the wall surface, and its surface is decorated with paint, brickwork, or other finishing treatments consistent with the wall surface to achieve concealment. The guide rings 62 can be made of copper, have a circular structure, and have an inner diameter slightly larger than 100 mm. The diameter of the concealed down conductor is specified. Multiple guide rings 62 are arranged at equal intervals along the height direction of the guide cover 61. The concealed down conductor 3 passes through multiple guide rings 62 to achieve the limiting and fixing of the concealed down conductor 3. The connecting rod 63 can be made of stainless steel. Multiple connecting rods 63 are evenly distributed between the guide rings 62 and the guide cover 61, with a quantity of 4-6 pieces. One end is welded and fixed to the guide ring 62, and the other end is welded and connected to the guide cover 61 to ensure the installation stability of the guide rings 62, thereby ensuring the limiting and fixing of the concealed down conductor 3 within the concealed structure 6.

[0035] In some embodiments, the concealed structure 6 further includes a plurality of constraint pieces 64, which are uniformly arranged in a ring on the base plate of the guide ring 62. They can be made of elastic copper sheet material. A clamping space is formed between the plurality of constraint pieces 64. After the concealed lead wire 3 passes through the guide ring 62, it is elastically clamped by the constraint pieces 64, which not only prevents the concealed lead wire 3 from shaking and shifting, but also accommodates the slight deformation of the concealed lead wire 3 and avoids scratching the surface of the concealed lead wire 3.

[0036] refer to Figure 7 A method for installing an integrated lightning protection structure for the roof of an ancient building, used to install the lightning protection structure of any of the above embodiments, includes the following steps: Step S1: Data Acquisition; The overall dimensions of the roof, ridge height, slope, and appearance, size parameters, and material type of the original ridge tile 21 of the ancient building 2 were accurately measured using a laser rangefinder and a 3D scanner. At the same time, the location information of the hidden parts of the gable wall was recorded and the data was compiled into a 3D model to provide a basis for the subsequent design and installation of components.

[0037] Step S2: Lightning strike simulation; Input the parameters collected in step S1 into lightning simulation software (such as PSCAD / EMTDC) to establish a lightning strike model of the roof of ancient building 2. Set typical lightning parameters and conduct repeated simulation tests. Locate the lightning-prone points on the roof of ancient building 2 through data analysis, mark the coordinates of each point, and provide accurate positioning for the arrangement of lightning protection units.

[0038] Step S3: Connect flash pole 1 and install flash net; Install lightning rod 1 at the intersection of the roof ridges at the top of the middle of the ancient building 2 to ensure that its protection range covers the central area of ​​the roof; remove the original ridge tiles 21 corresponding to the lightning-prone points on the roof of the ancient building 2 one by one, install lightning-blocking units at each lightning-prone point, and connect multiple lightning-blocking units in series through lightning-blocking wire 53 so that multiple lightning-blocking units form a complete lightning-blocking mesh on the roof.

[0039] Step S4: Integrated installation of the lightning arrester; Concealed down conductors 3 are laid in the hidden parts on the side of the ancient building 2. The bottom of the concealed down conductors 3 is welded and fixed to the grounding device 4, and the top is electrically connected to the lightning rod 1 and the lightning conductors 53 of multiple lightning units respectively, so as to complete the connection between the lightning arrester, down conductors and grounding device and realize integrated assembly.

[0040] A groove is made in the brick joint inside the eaves of the gable of the ancient building 2. The concealed down conductor 3 passes through the guide ring 62 of the hidden structure 6. The concealed down conductor 3 is clamped by the elastic deformation of multiple restraint plates 64 to ensure that the concealed down conductor 3 does not shake. The bottom of the concealed down conductor 3 extends to the grounding device 4. The bottom of the concealed down conductor 3 is welded and fixed to the grounding device 4. After anti-corrosion treatment, the soil is backfilled and compacted in layers. The guide cover 61 is installed in the groove, flush with the wall surface, and the surface of the guide cover 61 is decorated to make it blend into the wall surface. The top of the concealed down conductor 3 is connected to the lightning rod 53 and the bottom flange of the lightning rod 1 by welding.

[0041] Step S5: Testing and Acceptance; The electrical continuity and grounding resistance of the entire lightning protection structure are tested to ensure compliance with national lightning protection standards.

[0042] In some embodiments, step S3 includes the following steps: Step S31: At the location corresponding to the lightning strike point, gently tap the original ridge tile 21 with a hand tool to separate the original ridge tile 21 to be replaced from the surrounding original ridge tiles 21 and remove it. Avoid using power tools to prevent vibration from damaging the surrounding roof structure. After removal, clean the base layer of debris and check the integrity of the base layer, and repair any damaged parts.

[0043] Step S32: Fill the cavity of the upper original ridge tile 21 with the same traditional mortar as the original building, such as hemp fiber mortar and lime plaster. Cut a groove at the corresponding position at the bottom of the lower original ridge tile 21 and fill it with the same traditional mortar as the original building. Perform mortar placement. Insert and fix the locking block 521 of the reinforcing structure 52 into the groove, pressing it downwards at an angle to allow the locking block 521 to slide on the slide rail 523, reducing the overlapping area between the top of the connecting ridge tile 51 and the upper original ridge tile 21 until the connecting ridge tile 51... After there is no overlapping area between the top and the original ridge tile 21, the top of the lightning ridge tile 51 is inserted into the lower surface of the original ridge tile 21. It is then slowly released so that the bottom of the original ridge tile 21 is pressed against the top of the lightning plate 513. The bottom of the lightning ridge tile 51 is then placed steadily on the original ridge tile 21 below, so that its top and bottom form a natural overlapping relationship with the original ridge tiles above and below, ensuring a smooth roof outline and smooth drainage. The tile joints are then grouted using traditional techniques.

[0044] Step S33: Lay the lightning-catching wire 53 along the overlapping gap of the roof ridge tiles to the bottom of one side of the lightning-catching ridge tile 51, pass it through the connecting half ring 516 and weld it to the lightning-catching plate 513. The weld is tin-plated and wrapped with sealant to prevent rainwater from seeping in and corroding, thus completing the connection between a single lightning-catching unit and the lightning-catching wire.

[0045] In some embodiments, lightning rods can be vertically installed at fittings such as the ridge beam, the ridge tip, and the raised foot. These can be made by bending and wrapping copper wire around the fitting, with the lightning rod protruding from the highest point of the fitting. The bottom of the lightning rod is welded and fixed to the concealed down conductor 3. Simultaneously, the lightning rod 1 can be a telescopic structure and can be equipped with a collector, controller, and monitoring device to sense lightning. The signal collector is used to collect lightning and weather information from weather forecasts. The signal collector may include a wind speed sensor, a pressure sensor, a sound sensor, a radar sensor, and a weather forecast acquisition unit connected to a network. The weather forecast acquisition unit is used to obtain weather and lightning information from the network. The controller is connected to the signal collector and to the drive device. The controller acquires the lightning signal detected by the signal collector and converts it into a control signal, which is sent to the drive device. The drive device controls the raising, lowering, or reversing of the lightning rod according to the control signal. The monitoring device is connected to the controller and is used to input control signals to the controller, which then transmits the control signals to the drive device.

[0046] In practical applications, the drive unit includes a lifting drive motor and a tilting drive motor. Both motors are connected to a controller. The lifting drive motor is connected to the lightning arrester rod 1 and drives it to rise and fall. The tilting drive motor, also connected to the lightning arrester rod 1, drives it to tilt. This allows the lightning arrester rod 1 to be concealed when there is no lightning, better preserving the original appearance of the ancient building. During thunderstorms, the lightning arrester rod 1 is positioned vertically to maximize its lightning protection effect.
