Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0021] refer to figure 1 and figure 2 , the embodiment of the present invention provides a combined working platform, the working platform is fixedly installed on the steel box arch. The working platform includes an upper truss 1 , a lower truss 2 , a left truss 3 and a right truss 4 . The upper truss 1 is welded by square steel, the lower truss 2 is welded by square steel and round steel, and the left truss 3 and right truss 4 are respectively welded by equilateral angle steel. The upper truss 1 is fixed with the left truss 3 and the right truss 4 through the first bolt 5, and the lower truss 2 is hinged with any one of the left truss 3 and the right truss 4. In this embodiment, the lower truss 2 is hinged with the right truss 4, and through The second bolt 6 fixes the connection between the lower truss 2 and the left truss 3 and the righ...

Abstract

The invention discloses a combined operating platform and belongs to the field of manufacturing and construction of a bridge steel structure. The combined operating platform is fixedly mounted on a steel box arch; the combined operating platform comprises an upper truss, a lower truss, a left truss and a right truss; the upper truss is fixed with the left truss and the right truss through a first bolt; and the lower truss is hinged with any one of the left truss and the right truss and is fixed through a second bolt. The combined operating platform is convenient to mount and dismount and is high in safety.

Description

technical field [0001] The invention belongs to the field of bridge steel structure manufacturing and construction, and in particular relates to a combined working platform. Background technique [0002] At present, in the manufacture of bridge steel structures, steel box arches and steel pipe arches are widely used in modern bridge construction. Many existing bridges are outward-inclining steel box arches with variable cross-section. The east and west steel box arches incline outward at a certain angle from the center line of the bridge. The characteristics of station work. [0003] The high-altitude operation of the steel box arch must build a construction platform. The existing solutions mostly use full-height brackets or weld construction platforms in the construction area. However, no matter what kind of construction platform is used, not only the cost is high, but also the installation itself is very difficult, and the safety is also very low, especially the construc...
