A kind of manufacturing method of stainless steel rectangular tube support beam

Abstract

The invention relates to the technical field of steel structure supporting, and discloses a stainless steel rectangular pipe supporting beam manufacturing method. Two pieces of T-shaped steel are manufactured into framework I-shaped steel of a supporting beam, and the tangent vertical face of each piece of T-shaped steel is of a trapezoid structure through tangent contact oblique lines of the twopieces of T-shaped steel, wherein the trapezoid structures of the two pieces of T-shaped steel are the same in shape. During manufacturing, a stainless steel rectangular pipe is placed on a horizontalbase table, and the two pieces of T-shaped steel of the trapezoid structure are oppositely beaten from two ports of a thin-wall stainless steel rectangular pipe and along the tangent contact obliquelines of the two pieces of T-shaped steel to form a combined I-shaped steel structure. Then, a cavity is fully filled with expansion cement serving as a filling body, and then the stainless steel rectangular pipe supporting beam is manufactured. The stainless steel rectangular pipe supporting beam can resist bending and torsion, and a guide rail beam high in precision is manufactured. The functions of attractiveness, decency, rust preventing and acid and base preventing are achieved, and the beneficial effects of strength, rigidity, bending resistance, torsion resistance, shock resistance andstability are achieved. The quality guarantee can be provided for beam assembling, and the supporting strength is improved.

Description

technical field [0001] The invention relates to the technical field of steel structure support, in particular to a method for manufacturing a stainless steel rectangular tube support beam. Background technique [0002] At present, the existing steel structure support beams generally adopt cast metal entities. The production process of the cast steel structure support beams is complex and difficult, and the steel structure support beams are heavy and the production cost is high. Therefore, the existing steel structure support beams The beam cannot meet the needs of large-scale equipment installation and large-scale workpiece placement that require relatively less precision. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a method for manufacturing a stainless steel rectangular tube support beam. [0004] In order to realize the above-mentioned purpose of the invention, the present invention adopts following ...
