Built-in installation platform for bridge tower lightning rod and method for installing lightning rod with it

Abstract

The invention relates to a built-in type mounting platform for a lightning rod of a bridge tower and a method for mounting the lightning rod through the mounting platform. The bridge is a cable-stayed bridge or a suspension bridge. The mounting platform is composed of inner and outer casings of certain heights, a plain steel inner tube of the outer casing is connected with a bridge crown through a shear key, plain steel upper and lower ends of a plain steel tube of the inner casing and stainless steel outer thread steel tubes are welded together through a welding steel tube connecting plate, the stainless steel outer thread steel tubes are connected with a lightning rod base plate and a handle connecting plate, a mounting handle is welded on the handle connecting plate, and the inner and outer casings are in threaded connection. The mounting method comprises the steps of embedding the outer casing on which the shear key is welded, placing concrete, fixing the lightning rod on the lightning rod base plate, enabling the lightning rod and the inner casing to penetrate the outer casing by rotation, and stretching the lightning rod in place. By means of the mounting platform and the method, mounting and maintenance of the lightning rods of high bridge towers can be completed in the towers, out-of-tower high-altitude operations can be avoided, landscape requirements for the bridge towers are met, components outside bridge tower crowns are not added, the stability and operability are good, the mounting is simple, and the maintenance is convenient.

Description

technical field

[0001] The invention relates to a bridge, mainly a cable-stayed bridge, a suspension bridge tower lightning rod built-in installation platform and a method for installing the lightning rod. Background technique

[0002] The lightning rod is a lightning protection device that must be installed on the towering tower structures of cable-stayed bridges and suspension bridges. The traditional lightning rod installation requires a large platform space on the top of the bridge tower, and the construction personnel must be able to easily reach the installation platform for operation, which limits the shape of the bridge tower. As people pay more and more attention to the aesthetics of bridge structures, the bridge tower structure itself not only meets the structural force requirements, but also endows the structure with an aesthetic function through its own shape.

[0003] The Wusu Bridge on Heixiazi Island in Heilongjiang Province is located in the Fuyuan Delta (al...
