Building steel structure, what are the steel structure buildings

Steel frame installation process and process Steel frame installation process and process Steel structure has the advantages of high strength, good seismic performance and fast construction speed, so it is widely used in high-rise and super high-rise buildings. Its disadvantages are large amount of steel, high cost and high fire protection requirements. The steel structure systems used for high-rise buildings are:

Frame system, frame shear wall system, frame tube system, composite tube system, staggered steel truss system, etc. The cylinder system has good lateral force resistance, and the high-rise steel structure buildings with great height mostly adopt frame tube system and composite tube system. For example, the 10-storey, 41m-high World Center in New York, USA, is a frame tube system, with steel columns and frame tubes on the outside and steel frames on the inside.

The 109-storey, 405-meter-high Sears Tower in Chicago, USA, is a modular tube system, with 4 floors (including one basement floor) and a height of 153 For more information, please consult Tianjin....

The following meanings of each symbol can be compared and not explained in detail one by one

q: yield strength (the first letter of the Chinese character for "yield");

Nume: Intensity value;

A-E: Quality Grade;

f: boiling steel;

g: high-strength steel (the first letter of the Chinese character "high");

NH: weathering steel (the first letter of the Chinese character for "weathering");

J: Structural steel (the first letter of the Chinese character for "knot");

Z: calm steel, can not be written (the first letter of the Chinese character "Zhen"), there is also a meaning: Z steel, resistant to layered tearing steel, generally thick steel plates are more prone to layered tears, because the thicker the steel plate, the more non-metallic inclusion defects, and the thicker the weld, the greater the welding stress and deformation.

The mark of the Z-direction steel plate produced in China is to add the Z-direction steel plate grade mark Z15, Z25, Z35 after the parent steel number, and the number behind the Z word is the index (%) of the cross-section shrinkage

steel plate symbols; l: angle steel symbol;

H: H-shaped steel symbol, where Hw represents the wide flange, HM represents the middle flange, and H represents the narrow flange;

For example: Q235GNHCZ25: indicates the yield strength of 235MPa, high-strength weathering steel, quality grade C, calm steel, and the shrinkage rate of Z-direction tear section is 25%;

HM600*300*14*23: It means the middle flange H-beam, the web height is 600mm, the flange width is 300mm, the web thickness is 14mm, and the flange thickness is 23mm.

1. Towering steel structureThe towering structure includes TV towers, microwave towers, communication towers, high-voltage transmission line towers, petrochemical towers, atmospheric monitoring towers, rocket launch towers, tourist towers, drilling towers, exhaust towers, water towers, chimneys, etc. , and most of the towering structures are steel. With a height of 336 meters, the Heilongjiang TV Tower is the tallest multi-functional steel structure TV tower in China.

With the development of information and electricity, steel towers of about 50 meters will be all over China.

2. Large oil depots, gas depots, furnace shells and other containers with closed plate and shell steel structures. It can accept the large internal force of Chongqing steel structure and the sharp change in temperature. Large-diameter high-pressure oil pipelines are all plate-shell steel structures, and some larger ship locks and gates of hydraulic buildings are also plate-shell structures.

The structure is mainly composed of beam steel, steel columns, and steel trusses, and has undergone silanization treatment, pure manganese treatment, washing and drying, rust removal, galvanization, etc. The components are usually welded, screwed or riveted together.

At present, all countries in the world, especially developed countries and regions, steel structures have been widely used in the field of construction engineering. Steel structures can usually be divided into 5 categories: light steel structure, high-rise steel structure, residential steel structure, space steel structure and bridge steel structure.

Light steel structure - mainly used in load-bearing buildings that do not bear large loads, using light H-shaped steel as portal steel frame support, C-type or Z-type cold-formed thin-walled steel as wall beams, profiled steel plate as roof or enclosure structure, with seismic resistance, wind resistance, durability, heat preservation, sound insulation and other characteristics.

High-rise steel structure - generally refers to the structural system of six floors or more than 30 meters, which is connected or welded by section steel and steel plates, and is widely used in modern high-rise and super high-rise steel structures.

A steel structure is a structure made up of steel materials. Steel structure is a structure composed of steel materials and is one of the main types of building structures.

The structure is mainly composed of beam steel, steel columns, steel trusses and other components made of section steel and steel plates, and adopts silanization, pure manganese phosphating, washing and drying, galvanizing and other rust removal and rust prevention processes.

Welds, bolts or rivets are usually used to connect the individual components or components. Because of its light weight and simple construction, it is widely used in large-scale factories, venues, super high-rise buildings and other fields.
