Abstract

The invention relates to a steel column and beam structure used in the building and a welding device thereof, particularly discloses a steel column and beam structure with a corrugated steel web and a special welding device thereof. The steel column and beam structure comprises an upper wing plate, a lower wing plate and a web plate arranged between the upper wing plate and the lower wing plate, wherein the upper wing plate and the lower wing plate are made of plates with the thickness of 4-30mm, the web plate is a corrugated steel web plate with the thickness of 4-10mm, and the surfaces of the upper wing plate, the lower wing plate and the web plate are prepared with 50-500Mu m of roughness; the welding device of the steel column and beam structure with the corrugated steel web comprises a welding tractor and a welding gun arranged on the welding tractor, wherein tool sliding bars which are symmetrical are arranged on the welding tractor, a magnetic adsorption piece is arranged at the bottom of the welding tractor, four driving wheels are symmetrically arranged at two sides of the magnetic adsorption piece, and a track positioning retainer is arranged in a bracket at the middle part of the welding tractor. The middle web plate adopts the corrugated steel web plate, the steel beam and column with the corrugated steel web is welded by using the special welding device, therefore, the invention has the advantages of light weight and strong earthquake resistance.

Description

technical field [0001] The invention relates to a steel column steel beam structure and a welding device used in construction, in particular to a corrugated steel web steel column steel beam structure and a special welding device. Background technique [0002] Ordinary I-beams generally consist of an upper wing, a lower wing and a web. Among them, the web of the general I-beam steel girder adopts ordinary steel plates, such as the invention patent No. 200810063903.9 applied by Harbin Institute of Technology, the application date is January 23, 2008, and the announcement date is July 23, 2008. The notification number is CN101225687, and the name is a wedge-shaped honeycomb I-steel component, the upper end surface of the I-steel web is fixed with a section steel upper flange, and the lower end surface of the I-steel web is fixed with a section steel lower flange , the wedge ratio formed by the upper end surface and the lower end surface of the I-shaped steel web is α. The I-s...
