Description

Technical Field

[0001] This utility model belongs to the field of lightning protection structure technology in building construction, specifically relating to a waterproof lightning protection device for the roof of a steel structure building. Background Technology

[0002] In recent years, with the widespread application of prefabricated steel structure building metal roofs and a large number of electronic devices, roof lightning rod systems have become an important part of building structures to prevent lightning strikes. Currently, the conventional practice for roof lightning protection devices is to pass the lightning rod through the parapet wall cover and weld it to the joists to form the lightning protection system. This method damages the aluminum coping, affects the sealing effect of the coping edges, and poses a risk of water leakage.

[0003] Traditional lightning protection methods involve direct-entry lightning rods that pass through an aluminum capping plate on the parapet wall and are welded to the keel. However, the design thickness of the aluminum capping plate is limited, typically 0.4mm, as thicker plates are difficult to bend. This method requires drilling holes in the capping plate, significantly increasing the risk of water seepage. Therefore, a waterproof lightning protection device that bypasses the aluminum capping plate on the steel structure roof is needed to solve the problem of water seepage into the wall caused by existing lightning rods passing through the capping plate.

The fixed plate and the movable plate are respectively provided with connecting rod grooves at their respective positions. The connecting rod grooves clamp the two sides of the lightning arrester connecting rod.

[0007] Specifically, the fixed plate has a through hole, the movable plate has a threaded hole, the threaded hole is internally threaded to a clamping bolt, the clamping bolt passes through the through hole, and a locking nut is threaded to the clamping bolt.

The outside of the holes at the connection between the inner lining plate 10 and the lightning arrester rod 1 is treated with sealant. This prevents water from entering the wall, avoids the risk of roof leaks, solves rework problems, and saves costs.

[0023] The connecting rod lightning arrester 3 is provided with a fixed plate 301, a movable plate 302, a connecting rod groove 303, a clamping bolt 304, and a locking nut 305. The bottom of the fixed plate 301 is welded and fixed to the top of the vertical connecting rod. The fixed plate 301 and the movable plate 302 are provided with connecting rod grooves 303 at opposite positions. The connecting rod grooves 303 clamp the two sides of the lightning arrester connecting rod 2.

[0024] The fixed plate 301 has a through hole, and the movable plate 302 has a threaded hole. The threaded hole is internally threaded to connect to the clamping bolt 304. The clamping bolt 304 passes through the through hole, and the clamping bolt 304 is threaded to connect to the locking nut 305. The locking nut 305 is located on the outside of the movable plate 302.

[0025] The connecting rod positioning component 4 is provided with a "U" shaped clip 401, a fixing ear 402 and an outwardly expanding bending plate 403. The "U" shaped clip 401 is provided with fixing ears 402 on both sides. The fixing ears 402 are provided with mounting holes. Bolts pass through the mounting holes and are threaded into the threaded holes at the bottom of the horizontal steel keel 5. The "U" shaped clip 401 installs the lightning protection connecting rod 1 at the bottom of the horizontal steel keel 5.

[0026] An outwardly expanding bend plate 403 is provided on one side of the "U"-shaped card 401. The outwardly expanding space formed by the outwardly expanding bend plate 403 allows the stop block 101 to pass through. The stop block 101 is welded to the lower part of the "C"-shaped bend.

[0027] The bottom of the horizontal steel keel 5 is fixedly connected to the vertical steel frame 6, and the space between the vertical steel frames 6 is filled with walls. The outer side of the wall is provided with an integrated exterior wall panel 9 with thermal insulation and decoration, and the inner side of the wall is provided with an inner lining panel 10.
