Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a construction method for a lightning protection device for antique-style buildings. Background Technology

[0002] Ancient-style buildings often feature sloping roofs with steep inclines and upturned eaves, making them highly susceptible to lightning strikes. These unique characteristics necessitate lightning protection systems that differ from those of modern buildings. Lightning protection for ancient-style buildings should be implemented without damaging structural components. Lightning protection strips (nets) should be laid along the ridge, hip ridges, gable ridges, and eaves—areas prone to lightning strikes. Roof ornaments such as ridge beasts should be placed below the lightning protection strips (nets), and the strips should extend at least 15cm beyond the ends of the hip and gable ridges. However, the lightning protection strips at the ridge and eaves are easily damaged by natural erosion, compromising the overall aesthetic appeal of the ancient-style building and potentially damaging the ridge tiles during repairs. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a construction method for lightning protection devices in antique-style buildings, comprising the following steps:

[0004] S1. Use hot-dip galvanized flat steel and copper wires to lead out the foundation plate;

[0005] S2. The down conductor is formed by welding the main reinforcement bars of the frame structure column to form a good conductor. At the same time, test connection plates are set at the four corners of the building.

[0006] S3. The roof steel mesh and the inner steel bars of the parapet wall capping plate are used as lightning arresters, and the lightning arresters are electrically welded to the main reinforcement of the structural beam that forms a horizontal lightning arrester nearby.

[0007] S4. At the two ridge positions on the roof, hot-dip galvanized round steel is used, with one end welded to the steel bar inside the parapet wall capping plate, and the other end leading out of the roof panel.

[0008] S5. When constructing the blue brick masonry, the local equipotential bonding box and the main equipotential bonding box are buried. Then, the hot-dip galvanized flat steel and copper wires that have been led out from the foundation plate are connected to the main equipotential terminal box and the local equipotential terminal box.

[0009] S6. Install the lightning protection belt bracket at the ridge of the roof using metal top screws and buffer pads;

[0010] S7. Copper-plated round steel lightning protection strips are laid along the ridge of the building roof, and both ends are welded to hot-dip galvanized round steel at the vertical ridge.

[0011] S8. Conduct lightning protection test.

[0012] Preferably, in step S1, the hot-dip galvanized flat steel is 40mm x 4mm and the copper wire is BVX1 x 25mm.

[0013] Preferably, in step S2, the test connection plate is set at a distance of 0.5 meters from the ground from the lead wire.

[0014] Preferably, in step S4, the diameter of the hot-dip galvanized round steel is 10 mm.

[0015] Preferably, in step S6, the lightning strip bracket is made of matte stainless steel, and the distance between the lightning strip bracket and the roof is ≥15cm.

[0016] Preferably, in step S7, in addition to the decorative elements provided below the lightning receiving strip, a U-shaped clamp is used to fix it to the lightning receiving strip bracket.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] Copper-plated steel, which is highly stable, malleable, and has a color that better matches the antique architecture, is laid along the ridge and concealed at the eaves. Compared with the previous use of galvanized round steel, this improves the overall appearance of the building.

[0019] The copper material has extremely high stability, and the rest of the lightning protection strip and down conductor are all inside the structure, which effectively improves the material life and saves on later maintenance and replacement costs.

[0020] Because the down conductor is made of structural column steel reinforcement, safety is increased while eliminating the need to wrap the down conductor with cross-linked polyethylene, thus saving construction costs. Attached Figure Description

Detailed Implementation

[0029] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the embodiments described.

[0030] Please refer to Figures 1 to 6 A method for constructing a lightning protection device for antique-style buildings includes the following steps:

[0031] S1, such as Figure 5 As shown, the foundation plate is led out using 40mm x 4mm hot-dip galvanized flat steel 9 and BVX1 x 25mm copper wire 8;

[0032] S2, such as Figure 4 As shown, the down conductor is formed by welding the main reinforcement 7 of the frame structure column to form a good conductor. At the same time, test connection plates 4 are set at the four corners of the building, 0.5 meters above the ground.

[0033] S3, such as Figure 6 As shown, the roof steel mesh 5 and the steel bars inside the parapet wall capping plate serve as lightning arresters, and the lightning arresters are electrically welded to the main reinforcement bars 6 of the structural beam that form a horizontal lightning arrester nearby.

[0034] S4. At the two ridge positions on the roof, hot-dip galvanized round steel bar 3 is used, with one end welded to the inner steel reinforcement of the parapet wall coping slab, and the other end extending out of the roof panel, achieving the desired effect. Figure 3 As shown;

[0035] S5. During the construction of the blue brick masonry, the local equipotential bonding box and the main equipotential bonding box are buried. Then, the hot-dip galvanized flat steel 9 and copper wire 8 that have been led out from the foundation plate are connected to the main equipotential terminal box and the local equipotential terminal box.

[0036] S6. Install the lightning protection belt bracket 2 at the ridge of the roof using metal top screws and buffer pads. The lightning protection belt bracket 2 is made of matte stainless steel and the distance between the lightning protection belt bracket 2 and the roof is ≥15cm.

[0037] S7, such as Figure 2 As shown, the lightning protection strip 1 made of Φ10 copper-plated round steel is laid along the ridge of the building roof. The lightning protection strip 1 is fixed to the lightning protection strip bracket 2 using U-shaped (clamp-type) fasteners, and the two ends are welded to the Φ10 hot-dip galvanized round steel 3.

[0038] S8. Lightning protection test was conducted and completed with good results.

[0039] In this invention, the lightning protection strip 1 on the ridge is made of copper-plated steel, which has two major advantages: conductivity and service life close to copper, and construction cost and mechanical properties close to steel. Compared with other materials, it is better at diverting current and has good plasticity, making it suitable for the complex shape requirements of ancient buildings. The material color also coordinates with the historical building, resulting in a good visual effect and minimal impact on the ancient building. The lightning protection strip bracket 2 is made of matte stainless steel, with a height ≥15cm to ensure it does not rust and prevent contamination of the antique building's roof tiles by rust. Its fixing method uses a U-shape (hug) design. The lightning protection strip 1 at the top of the ridge uses a metal top screw and a buffer pad for fixing the lightning protection strip bracket 2 to the roof. Except for the part exposed on the roof, the down conductor uses the steel bars inside the concrete structural column as the natural down conductor. The steel bars of the concrete structural column are connected to the foundation steel mesh, and the foundation steel is used as the grounding body. Therefore, in this invention, the lightning protection strip 1 at the top of the ridge uses copper metal material with more stable properties. At the same time, the down conductor of the lightning protection strip 1 at the eaves is concealed. This can protect the down conductor while ensuring the overall appearance of the antique building, and also take into account the concealment of the lightning protection system to prevent safety accidents.

[0040] As described above, although the invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the invention itself. Various changes in form and detail may be made without departing from the spirit and scope of the invention as defined in the appended claims.
