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 ...
