Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] Method 1: Taking a steel beam composed of three layers of steel plates as an example, cut the width of the steel plate 2 according to the design requirements, then cut the length and grind the edges, and make screw holes for fixing the beam 3 and both ends of the steel plate 2 according to the designed steps , the one in front of the previous step of the 3 holes of the crossbeam and the one behind the next step must be perpendicular, and then the steel plate 2 is bent into the required radian with a three-roll plate rolling machine, and the steel pipe is cut into the size required by the crossbeam 3, and cut for the two beams of the crossbeam 3 The plug 8 at the end, make a center hole on the plug 8, weld the nut 9 on the back of the plug 8, when welding the nut 9, plug a positioning pin or screw 10 on the center hole to prevent the nut 9 from being ecc...

Abstract

Disclosed are a spiral steel frame staircase and a manufacturing method of the spiral steel frame staircase. The spiral steel frame staircase comprises steel beams, stair plates and guardrails. The spiral steel frame staircase is characterized in that each steel beam is formed by at least two layers of steel plates and the steel beams are connected with one another through cross beams. The spiral steel frame staircase and the manufacturing method of the spiral steel frame staircase have the advantages that needed parts are broken up into smaller parts, a screw joint mode is adopted, the problems that in manufacturing and transportation of a traditional steel staircase are inconvenient, on-site construction and welding are needed and installation is troublesome are avoided, working difficulty is reduced, the working efficiency is improved, and more importantly, the potential safety hazards existing in the construction process are avoided.

Description

technical field [0001] The invention relates to a staircase, in particular to a steel frame spiral staircase and a manufacturing method thereof. Background technique [0002] Stairs play a vital role as a communication tool for the upper and lower spaces in modern houses, but traditional steel stairs require on-site construction and welding, which is not only cumbersome to transport and install, but also difficult to work and takes a long time, but the efficiency is not high, more importantly The most important thing is that there are safety hazards in the construction, and the steel ladder can only be painted manually, and phosphating and electrostatic spraying cannot be carried out. Compared with artificial paint, the protection is poor and the aesthetics is slightly inferior. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a spiral staircase with a steel frame that is beautiful in appearance, convenient and qu...
