Lightning protection device for high-rise building roof

Abstract

The invention discloses a lightning arrestor used for the roof of a high-rise building. The lightning arrestor comprises a foundation pier and a casing pipe. A protrusion is arranged on the upper section of the inner wall of the casing pipe. An inner thread is arranged on the inner circumferential wall of the protrusion. The lower section of a connecting rod is matched with the protrusion through the thread. The upper section of the connecting rod is provided with a horizontally-arranged limiting pipe. A cylindrical direction-changing block is fixed to the middle portion of the limiting pipe. A straight hole is formed in the middle of the direction-changing block in the axis direction of the limiting pipe. Gaps are reserved between the two side walls of the direction-changing block and the inner wall of the limiting pipe. By adoption of the lightning arrestor, large-scale building roof lightning protection treatment can be fast achieved, the overall building attractiveness is not affected, and meanwhile, the difficulty and workload for laying a lightning strip are reduced; concrete is poured into a plastic pipe with a certain diameter, the casing pipe is pre-buried in the plastic pipe, the plastic pipe is directly removed after the concrete is solidified, and the foundation pier is formed; and the foundation pier is manufactured through drainage pipelines on a construction site and the building concrete, and the lightning strip laying cost is greatly lowered.

Description

technical field [0001] The invention relates to the field of building lightning protection, in particular to a lightning protection device for the roof of a high-rise building. Background technique [0002] The lightning protection grounding system of high-rise buildings is composed of internal lightning protection grounding device and external lightning protection grounding device. The internal lightning protection grounding device includes: cage lightning protection net and special grounding device. Lightning protection belts and pressure equalizing rings to improve the reliability of the overall lightning protection of the building. In the lightning protection of high-rise buildings, the method of using a flat metal strip instead of a steel wire is called a lightning protection belt, which is improved from a lightning protection line. On high-rise buildings in the city, the use of lightning protection belts has more advantages than lightning rods. It can be combined with...

AI Technical Summary

Problems solved by technology

In view of the heavy workload and high difficulty of laying the lightning protection belt on the roof of the existing steel structure building, the applicant designed a new lightning protection belt, which can quickly realize the lightning protection treatment of a large-scale building roof, and ensure the lightning protection level of the building. It does not affect the overall aesthetics of the building, and at the same time reduces the difficulty and workload of laying the lightning protection belt; when the foundation pier is made, concrete is poured in a plastic pipe with a certain diameter, and the casing is pre-embedded in the plastic pipe. After the concrete is solidified, the plastic pipe is removed directly, and the foundation pier is formed, that is, the foundation pier is realized through the drainage pipes on the construction site and the building concrete, which greatly reduces the cost of laying the lightning protection belt;
