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;

Embodiment 1

[0026] Such as Figure 1~3 As shown, this embodiment includes a foundation pier 1 formed by concrete pouring and a casing 2 pre-buried in the foundation. The upper section of the inner wall of the casing 2 is provided with an annular protrusion, and on the inner circumferential wall of the protrusion It is provided with internal threads, the lower section of the connecting rod 3 is matched with the protruding thread, the upper section of the connecting rod 3 is provided with a horizontal limit tube 5, and in the middle of the limit tube 5 is fixed a cylindrical direction changing block 7 along the limit In the axial direction of the position tube 5, a straight hole 8 is opened in the middle of the direction changing block 7, and a gap is left between the two side walls of the direction changing block 7 and the inner wall of the limit tube 5, and the gap allows the steel bar 4 to pass through. . In view of the large workload and difficulty of laying lightning protection belts on...

Embodiment 2

[0031] Such as Figure 1~4 As shown, in this embodiment on the basis of Embodiment 1, the limiting tube 5 is in a circular arc shape, and the two ends of the straight hole 8 are facing the two open ends of the limiting tube 5. Preferably, the limit tube 5 is set in a circular arc shape, so that when the lightning protection belt is laid on the roof of a circular steel structure house, the steel bar 4 can be used between the redirection block 7 and the inner wall of the limit tube 5 when passing through the pipe. The arc-shaped space is subjected to a certain degree of bending deformation to ensure that the formed lightning protection belt maintains its stability and prevent the local stress concentration of the formed lightning protection belt from changing the position of the supporting foundation pier 1.

[0032] The middle part of the outer wall of the redirecting block 7 is recessed inward to form a redirecting surface that matches the reinforcing steel 4. The middle of the ...

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 consists of an internal lightning protection grounding device and an external lightning protection grounding device. The internal lightning protection grounding device includes: cage lightning protection net, special grounding device, and the external lightning protection grounding device includes: grounding net, down conductor, Lightning protection belt and equalizing ring to improve the reliability of the overall lightning protection of the building. In the lightning protection of high-rise buildings, the method of replacing the steel wire with a flat metal strip is called a lightning strip, which is an improvement from the lightning strip. In urban high-rise buildings, the use of lightning belts has more adva...
