Problems solved by technology

[0003] However, there are still many problems in the existing steel structure processing. For example, the existing processing technology is unreasonable, resulting in repeated or excessive processing of steel components, which seriously affects product quality and high production costs.
In addition, most of the existing steel structures use spray paint to prevent corrosion, and most of them need to be sprayed 3 to 4 times, and they are easy to fall off and unsightly. Therefore, it is necessary to invent a steel structure processing technology to solve the above problems

Embodiment 1

[0081] A steel structure processing technology, comprising the steps of:

[0082] 1) Raw material inspection:

[0083] Raw material inspection to ensure that all raw materials meet the current national and industry standards; among them, the steel materials in the raw materials are Q345B steel and Q235B steel; the bolts are 10.9-grade torsional shear type high-strength bolts; the anti-skid coefficient of the Q345B steel surface should not be less than 0.45 , the anti-skid coefficient of Q235B and steel of the same material shall not be less than 0.4;

[0084] 2) Lofting and nesting:

[0085] Stake out before processing, and check whether there is any error in the drawing. After checking, use the drawing for nesting. Before nesting, familiarize yourself with the drawing and process requirements, and then carry out the numbering; after the steel plate is marked, mark the reference line and center line and inspection control points; the joints of the components need to be clear...

Abstract

The invention discloses a steel structure machining process. The steel structure machining process is characterized by comprising the steps that (1) raw materials are inspected; (2) laying off and jacking are carried out; (3) discharging and cutting are carried out; (4) material receiving is carried out; (5) H-shaped steel assembling and welding are carried out; (6) steel columns are manufactured;(7) roofing beams are manufactured; (8) crane beams are manufactured; (9) drilling is carried out; (10) rust removal and corrosion resistant are carried out; and (11) assembly is carried out. According to the steel structure machining process, the obtained steel structure has high quality, the percent of pass reaches more than 99%, the machining process sequence is reasonable, the cost is effectively reduced, meanwhile, the corrosion resistant performance of steel components is improved, the service life is prolonged, and the product performance is improved.

Description

technical field [0001] The invention belongs to the technical field of building component preparation, and in particular relates to a steel structure processing technology. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate, and adopts rust removal and antirust technology. The components or components are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large factories and other fields. The steel structure system has comprehensive advantages such as light weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. With the unique advantages of development in three aspects, steel st...
