Description

Technical Field

[0001] This invention relates to the field of lightning protection devices, and particularly to a lightning protection device for building roofs. Background Technology

[0002] Lightning, as a highly destructive natural phenomenon, poses a serious threat to the structural safety of buildings and the safety of internal equipment and personnel. Therefore, building lightning protection systems are an indispensable and important component of modern construction engineering. The lightning protection and lightning arrestor on the building roof, as the core front-end component of the lightning protection system, is mainly used to directly receive lightning and quickly conduct the lightning current to the ground, thereby preventing damage to the building from lightning strikes. Among them, the lightning arrestor strip is the most widely used component in roof lightning arrestor systems. It is usually made of metal conductors laid on the building roof, and through uniform distribution, it forms a complete lightning arrestor network, which can effectively cover the roof protection area, achieving the interception and diversion of lightning, and ensuring the overall lightning protection safety of the building.

[0003] In the traditional installation of lightning protection strips on building roofs, due to the limitations of the strip's length, welding is typically used to secure the connection points between multiple strips to ensure continuous current transmission. However, these welded joints are directly exposed to the external environment, subject to long-term exposure to sunlight, rain, and temperature fluctuations. This makes the welds highly susceptible to oxidation, corrosion, and even cracking and breakage, reducing the strip's conductivity and directly impacting the reliability of the entire lightning protection system. Furthermore, traditional supports for the lightning protection strips and their stable connection to the roof are mostly single-pole structures with weak overall structural strength and wind resistance. During extreme weather events such as typhoons and strong winds, these supports are prone to swaying, deformation, or even detachment, failing to provide stable and reliable support for the strips and further exacerbating safety hazards associated with the lightning protection system. Summary of the Invention

[0004] The main objective of this invention is to provide a lightning protection device for building roofs, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A lightning protection device for a building roof includes a lightning-catching strip with several support brackets clamped and fixedly installed on it.

[0010] Preferably, the semi-annular sealing shell of the sealing protection component has two symmetrically formed guide holes, and an installation hole is formed on the semi-annular sealing shell between the two guide holes. Both the guide holes and the installation hole penetrate the inner and outer parts of the semi-annular sealing shell. The installation pin is inserted into the installation hole, and the installation pin is fixedly connected to the semi-annular sealing shell by welding. The installation pin has an internal thread hole that penetrates the inner and outer parts of the installation pin.

[0011] Preferably, the pipe formed by splicing two semi-annular sealing shells on the sealing protection component is sleeved on the outside of the welded connection of the lightning-catching strip, and the two conical pipes formed by splicing four sealing conical shells are also sleeved on the outside of the welded connection of the lightning-catching strip.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 - Figure 7As shown, a lightning protection device for a building roof includes a lightning-absorbing strip 1. Several support brackets 2 are clamped and fixedly installed on the lightning-absorbing strip 1. Each support bracket 2 consists of a semi-annular clamp 6, inclined support legs 7, and a fixed base plate 20. Two semi-annular clamps 6, two inclined support legs 7, and two fixed base plates 20 are provided. Two semi-annular clamps 6 are symmetrically spliced ​​to form a pipe. Two inclined support legs 7 are respectively fixedly installed on the outer walls of the two semi-annular clamps 6. Two fixed base plates 20 are respectively fixedly installed on the lower outer ends of the two inclined support legs 7. The two inclined support legs 7 are fixedly connected by bolts. A sealing protective element 3 is fixedly sleeved at the welded joint of the lightning-absorbing strip 1. The sealing protective element 3 consists of a semi-annular sealing shell 9, a mounting connecting plate 10, a sealing cone shell 11, an arc-shaped sealing clamp shell 12, and a mounting post 13. There are two semi-annular sealing shells 9 symmetrically spliced ​​to form a pipe. There are four mounting connecting plates 10, which are symmetrically fixedly installed in pairs on the outer walls of the two semi-annular sealing shells 9. There are four sealing cone shells 11. Two semi-annular sealing shells 9 are symmetrically fixed at both ends of each other. Four arc-shaped sealing clamping shells 12 are fixedly installed at the outer ends of four sealing cone shells 11. Two mounting pins 13 are fixedly inserted into the two semi-annular sealing shells 9. Two reinforcing clamping parts 4 are symmetrically installed on the sealing protection part 3. The reinforcing clamping part 4 consists of a clamping rod 17, a mounting guide rod 18, and a driving bolt 19. There are two mounting guide rods 18, which are symmetrically fixedly installed at the outer ends of the clamping rods 17. The driving bolt 19 is rotatably installed at the outer ends of the clamping rods 17. The clamping rods 17 are close to the welded connection of the lightning receiving strip 1. The down conductor 5 is fixedly installed on the lightning receiving strip 1 by welding. The lightning receiving strip 1 is located above the building wall 21. The down conductor 5 is also fixedly connected to the building wall 21. Due to the length specifications of the lightning receiving strip 1, multiple sections of the lightning receiving strip 1 are required for use. The connection between multiple sections of the lightning receiving strip 1 is usually fixed and conductive by welding to ensure the continuity of current transmission.

[0021] Specifically, the inclined support leg 7 on the support bracket 2 is fixedly connected to the semi-ring clamp 6 and the fixed base plate 20 by welding. The upper part of the inclined support leg 7 is provided with a mounting through hole 8 near the semi-ring clamp 6. The bolts for fixing the two inclined support legs 7 are installed in the two mounting through holes 8 on the two inclined support legs 7. The two inclined support legs 7 are in a figure-eight shape. The two semi-ring clamps 6 on the support bracket 2 are clamped on the lightning protection strip 1. The fixed base plate 20 is fixedly installed on the upper end of the building wall 21 by bolts. By setting the support bracket 2, which is composed of the semi-ring clamp 6, the inclined support leg 7 and the fixed base plate 20, the lightning protection strip 1 is supported and fixed. The figure-eight shaped inclined support leg 7 combined with the double fixed base plate 20 structure greatly improves the overall structural strength and wind resistance of the support bracket 2. It can effectively resist extreme weather such as typhoons and strong winds, prevent the support bracket 2 from shaking, deforming and falling off, provide long-term and stable support for the lightning protection strip 1 and reduce the overall safety hazards of the lightning protection device.

[0022] Specifically, the semi-annular sealing shell 9, mounting connecting plate 10, sealing cone shell 11, and arc-shaped sealing clamping shell 12 on the sealing protection component 3 are integrally formed structures. The semi-annular sealing shell 9 on the sealing protection component 3 has two symmetrically arranged guide holes 14. An installation insertion hole 15 is provided on the semi-annular sealing shell 9 between the two guide holes 14. Both the guide holes 14 and the installation insertion hole 15 penetrate the semi-annular sealing shell 9 internally and externally. The installation pin 13 is inserted into the installation insertion hole 15, and the installation pin 13 is fixedly connected to the semi-annular sealing shell 9 by welding. The installation pin 13 has an internal threaded hole 16 that penetrates the installation pin 13 internally and externally. The pipe formed by splicing the two semi-annular sealing shells 9 on the sealing protection component 3 is sleeved on the outside of the welded connection of the lightning protection strip 1. Four sealing cone shells... Two conical tubes, spliced ​​together, are also fitted onto the outside of the welded connection of the lightning protection strip 1. Two pipes, composed of four arc-shaped sealing clamp shells 12, are tightly fitted onto the lightning protection strip 1 on both sides of the welded connection. Four mounting connecting plates 10 on the outer walls of the two semi-annular sealing shells 9 are fixedly connected by bolts. By fixing a sealing protection component 3, composed of a semi-annular sealing shell 9, mounting connecting plates 10, sealing conical shells 11, arc-shaped sealing clamp shells 12, and mounting inserts 13, at the welded connection of the lightning protection strip 1, the sealing protection component 3 can seal and protect the welded connection of the lightning protection strip 1, isolate it from external sunlight, rain, temperature changes and other natural factors, effectively avoid oxidation, rust, cracking and breakage of the weld point, and ensure the long-term stability and reliability of the conductivity of the lightning protection strip 1 and the lightning protection system.

[0023] Specifically, the clamping rod 17 on the reinforcing clamping member 4 is movably installed inside the semi-annular sealing shell 9. The inner end of the clamping rod 17 has an arc-shaped groove. The clamping rod 17 is tightly attached to the welded connection of the lightning-catching strip 1 through the arc-shaped groove. The mounting guide rod 18 is movably installed in the mounting hole 15. The driving bolt 19 is installed in the internal threaded hole 16. The clamping rod 17 and the mounting guide rod 18 on the reinforcing clamping member 4 are fixedly connected by welding. By setting two reinforcing clamping members 4 on the sealing protection member 3, consisting of the clamping rod 17, the mounting guide rod 18 and the driving bolt 19, and cooperating with the internal threaded hole 16 on the mounting post 13, the two reinforcing clamping members 4 can clamp and reinforce the welded connection of the lightning-catching strip 1, improve the connection strength of the welded part, reduce the probability of the welded part of the lightning-catching strip 1 falling off, and thus further enhance the stability and conductivity continuity of the connection of the lightning-catching strip 1.

[0024] When installing the lightning protection device on the building roof, firstly, the multiple sections of lightning-absorbing strip 1 are welded into a complete strip according to the construction requirements. Then, the two semi-ringed clamps 6 of the support bracket 2 are symmetrically spliced ​​and clamped at the designated support position of the lightning-absorbing strip 1, so that the pipe formed by the two semi-ringed clamps 6 tightly wraps the lightning-absorbing strip 1. Next, the two inclined support legs 7 are fixedly connected by bolts through the installation through holes 8, so that the inclined support legs 7 with the V-shaped structure remain stable. Then, the fixing base plate 20 at the bottom of the support bracket 2 is firmly fixed to the upper end of the building wall 21 by expansion bolts, completing the support and fixing of the lightning-absorbing strip 1. Then, the sealing protection component 3 with the pre-installed reinforcing clamp 4 is fixedly sleeved at the welded connection of the lightning-absorbing strip 1. During installation, first align the inner arc groove of the clamping rod 17 on the reinforcing clamp 4 with and press it tightly against the welded connection of the lightning-absorbing strip 1. Then, the two semi-ringed clamps 6 are fixedly sleeved at the welded connection of the sealing protection component 3. The annular sealing shells 9 are symmetrically spliced, so that the four sealing cone shells 11 are spliced ​​into two cone tubes and the four arc-shaped sealing clamping shells 12 are spliced ​​into two pipes. They are tightly fitted onto the welding joint of the lightning protection strip 1 and the lightning protection strip 1 on both sides. Then, the four mounting connecting plates 10 on the outer wall of the two semi-annular sealing shells 9 are fixedly connected by bolts to complete the fixed installation of the sealing protection component 3. After that, the drive bolts 19 of the reinforcing clamping component 4 are rotated with a wrench or other tools so that the drive bolts 19 are screwed into the internal threaded hole 16 of the mounting post 13, pushing the clamping rod 17 to move further towards the welding joint of the lightning protection strip 1, so that the clamping rods 17 of the two reinforcing clamping components 4 further clamp and fix the welding joint of the lightning protection strip 1. Finally, the down conductor 5 is welded to the designated position of the lightning protection strip 1 and the down conductor 5 is laid along the building wall 21 to complete the grounding connection. At this time, the entire lightning protection device for the building roof is installed.

[0025] In addition, the inner diameter of the pipe formed by splicing the arc-shaped sealing clamping shells 12 is the same as the diameter of the lightning-catching strip 1, ensuring that the pipe can tightly fit the outer wall of the lightning-catching strip 1, thereby ensuring a good sealing and protective effect of the sealing protection component 3; the diameter of the mounting guide rod 18 is the same as the diameter of the guide through hole 14, which can ensure that the reinforcing clamping component 4 will not shake or shift during movement, ensuring accurate and stable clamping action, while ensuring a good sealing and protective effect of the sealing protection component 3; the inner diameter of the pipe formed by splicing the semi-ring clamping shells 6 is the same as the diameter of the lightning-catching strip 1, so that the support bracket 2 can firmly clamp the lightning-catching strip 1 without loosening; The sealing and protective component 3 consists of two identical parts. The contact surfaces of the two parts need to be smooth and flat to ensure a tight and gapless seal after splicing, preventing external moisture and dust from intruding into the welded position and affecting the lightning protection performance. The support bracket 2, the sealing and protective component 3, and the reinforcing clamp 4 are all made of hot-dip galvanized stainless steel. This material has excellent conductivity, mechanical strength, and weather and corrosion resistance, and can withstand long-term exposure to sunlight, rain, temperature changes, and atmospheric corrosion on the roof. At the same time, it ensures smooth electrical connection with the lightning protection strip 1, meeting the requirements for long-term stable use of the building roof lightning protection device.

[0026] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
