Main girder square steel splicing structure on escalator or moving pavement

Abstract

The invention discloses a main girder square steel splicing structure on an escalator or moving pavement. The structure comprises two pieces of main girder square steel, wherein the ends of the two pieces of main girder square steel are fixed together by permanent butt welding with backing; the backing is made of reinforced square steel; the two ends of the reinforced square steel are extended into cavities at the ends of the two pieces of main girder square steel respectively; the outer surfaces at the ends of the two pieces of main girder square steel are provided with a plurality of punched holes in which a melted soldering flux is filled; the main girder square steel and the reinforced square steel are plugged into each other for welding; the two pieces of main girder square steel are connected by butt welding through the reinforced square steel; and the main girder square steel and the reinforced square steel are plugged into each other for welding so as to form one piece of square steel. The length of the piece of square steel can meet the requirements of manufacturing a metal framework, and the piece of the square steel also meets the requirements of manufacturing the metal framework in mechanical property, so that unnecessary sectioning of the metal framework is reduced, and the manufacturing cost of the metal framework is reduced.

Description

Technical field [0001] The invention relates to a main beam square steel splicing structure on an escalator or moving sidewalk. Background technique [0002] At present, the standard square steel lengths on the market often cannot meet the requirements for the production of metal skeleton main beams of escalators and moving walks. This will increase the number of sections of the metal skeleton, making the structure of the metal skeleton unreasonable and increasing the production of metal The cost of making the skeleton. Summary of the invention [0003] The purpose of the present invention is to provide a square steel splicing structure with two main beams on escalators or moving walks that are welded and fixed together by reinforcing square steels to form a square steel with a length that can meet the requirements of metal skeleton production. [0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: the main beam square steel spli...
