Embodiment

[0039] Embodiment: This embodiment is a urea frame steel structure manufactured by Inner Mongolia Bodashidi 5080 Chemical Fertilizer Project. The main body height is 33.8m, the local height is 59.1m, the plane size is 46.4m×23.5m, six spans and three spans, and the total weight is 1700t.

[0040] The column is a box-shaped column, and the specifications of the box-shaped column are 800×650×36×36 (that is, the section length of the box-shaped column is 800, the width is 650, and the thickness of the panel is 36. The following specifications have the same meaning), 800×650×30×30, 650×650×28×28, 500×500×28×28, the beams are 1400×730×30×36, 1400×600×30×36, and the connecting beams are welded with H-shaped steel, and the materials are Q235C and Q345. The length is made in three sections.

[0041] figure 1 As shown, the large-scale steel structure includes columns 1 and beams 2, and the columns 1 are connected by beams 2 and connecting beams.

[0042] The column 1 is a box-shaped ...

Abstract

The invention relates to a large steel structure, belonging to the building field. The large steel structure comprises stand columns and cross beams, wherein the stand columns are connected with one another by the cross beams and connecting beams; the large steel structure is characterized in that the stand columns and the cross beams have box-shaped structures; each connecting beam comprises a cross connecting beam and an inclined connecting beam; each connecting beam is a welded steel H-section; each box-shaped structure consists of a front face plate, a rear face plate, an upper face plate, a lower face plate and a clapboard, a tetrahedron can be formed by welding the front face plate, the rear face plate, the upper face plate and the lower face plate, and the clapboard is arranged in an inner cavity of the tetrahedron; each connecting beam consists of an upper flange plate, a lower flange plate and a web; and the upper flange plate is connected with the lower flange plate by the web. The large steel structure reliably guarantees the manufacturing accuracy and quality of the steel structure, is high in degree of automation, adopts industrial production and flow process, improves the efficiency of labor, lightens the labor intensity of workers, and realizes industrial production and field installation.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a method for manufacturing a large-scale steel structure. Background technique [0002] In recent years, many large industrial installations, large buildings, and high-rise buildings have been designed with steel structures. Steel structure buildings are developing towards large-scale and high-rise buildings. Using traditional steel structure manufacturing equipment and methods, the manufacturing accuracy cannot meet the quality requirements, and the size of high-strength bolt holes exceeds the standard, which cannot meet the standard requirements, and the installation quality cannot be guaranteed. With the introduction of new special equipment for domestic steel structure manufacturing, steel structure production lines have begun to be popularized and applied. Contents of the invention [0003] The purpose of the present invention is to meet the needs of the current c...
