Prefabricated steel structure manufacturing and processing method

Abstract

The invention provides a prefabricated steel structure manufacturing and machining method. A prefabricated steel structure manufacturing and machining device is adopted in the prefabricated steel structure manufacturing and machining method, and comprises stair rib plates, steel plates and fixing units, the stair rib plates are symmetrically arranged, and the steel plates are arranged on the inner side walls of the stair rib plates at equal intervals through the fixing units. The method can solve the following problems that firstly, when a traditional steel structure stair is processed, the steel plates are manually lifted to the stair rib plates mostly, and then the steel plates are supported and fixed by workers, so that the stability is poor, the fixing effect is poor, the workers are prone to be fatigue due to long-term high-strength work, and the steel plates are prone to shift; and secondly, in general, after the steel plates are supported and fixed to the stair rib plates by the workers, the stair rib plates are marked, and then the inclination angles of the steel plates are manually adjusted so that the adjustment precision cannot be ensured, and the processing precision is influenced.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to a method for manufacturing and processing prefabricated steel structures. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The components or parts of the steel structure are usually connected by welding, bolts or rivets. The characteristics of steel are high strength, light weight, and overall rigidity. Good, strong resistance to deformation, good material plasticity and toughness, can have large deformation, and can withstand dynamic loads well; due to the light weight of the steel structure and easy construction, it is widely used in factory building construction, venue construction, super high-rise buildings And steel structure stairs and other fields, in which steel structure stairs have the advantages of less fulcrum, high load-bearing, more shapes, high technical content...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the production and processing of steel structure stairs at present: 1. When processing traditional steel structure stairs, steel plates are mostly lifted to the ribs of the stairs by hand, and then the steel plates are supported and fixed by workers, so they are stable The stability is poor, the fixing effect is poor, and long-term high-intensity work is easy to cause fatigue to the workers, so the steel plate is easy to shift;

[0004] 2. After the general workers fix the steel plate support to the stair rib, most of them draw lines on the stair rib, and then adjust the inclination angle of the steel plate by manual adjustment, so the accuracy of the adjustment cannot be guaranteed, which affects the processing accuracy
