What are the steel structural components and what are the metal structural components?

1. The steel structure components mainly include steel roof trusses, steel grids, steel brackets and steel trusses.

Steel columns, steel beams, steel floor slabs, steel supports, steel wall frames, steel purlins, steel platforms, steel ladders, steel railings, sporadic steel structures and so on.

Second, the general provisions for the assembly of steel structure engineering components:

1. The assembly of components should be carried out on the assembly platform, assembly support frame or special equipment, and the assembly platform and assembly support frame should have sufficient strength and rigidity, and should be convenient for the loading, unloading and positioning of components. On the assembly platform or assembly support frame, it is advisable to draw the center line, end face position line, contour line and elevation line and other reference lines of the component.

2. The component assembly can be carried out by using the ground sample method, the copy assembly method, the tire mold assembly method and the special equipment assembly method; When assembling, it can be vertical, horizontal, etc.

3. The component assembly gap should meet the requirements of the design and process documents, and the assembly gap should not be greater than when the design and process documents are not specified.

4. The welding shrinkage should be preset when the welded components are assembled, and the welding shrinkage should be reasonably distributed for each component. Important or complex components should be determined by manufacturability test to determine the amount of welding shrinkage.

5. The components that are required to be arched by the design should be arched according to the specified arching value when assembling, and the allowable deviation of the arching should not be greater than 10% of the arching value, and should not be greater than 10mmFor components that are not required by the design but required by the construction process, the allowable deviation of the arching shall not be greater than 10% of the arching value, and shall not be greater than 10mm.

6. a truss structure.

When assembling, the offset of the intersection of the member axis should not be greater than 3 mm.

7. a crane beam.

And the crane truss assembly, welding should not be allowed to deflect. The lower flange of the crane girder and the tension surface of the important stressed components shall not be welded with tooling fixtures, temporary positioning plates, temporary connecting plates, etc.

8. Dismantle temporary workers.

Fixtures, temporary positioning plates, temporary connecting plates, etc., are strictly forbidden to be shot down with a hammer, and should be removed by flame at a distance of 3mm-5mm from the surface of the component, and the residual welding scars should be polished and smoothed, and the base metal should not be damaged.

9. After the end of the component is milled flat, more than 75% of the area of the contact surface should be closely pasted, and the feeler gauge should be applied.

Check, its plugging area should be less than 25%, and the maximum gap at the edge should not be greater than.

Steel columns, steel beams, purlins, tie rods, corner braces, pull bars, door beams, door posts, window beams, window columns, high-strength bolts, ordinary bolts, grid (rods, balls) and so on.

The steel structure equipment is as follows: lifting equipment, cranes, forklifts; shearing machines, bending machines, drilling machines; H-beam production line, including CNC cutting machine, assembly machine, gantry welding, straightening machine, shot blasting machine, paint spraying; C Z-shaped steel purlin machine, color steel tile veneer machine; Box girder production line.

Steel structure equipment At present, in steel structure buildings, the wall envelope structure can be divided into two categories:

One is the block class, there are hollow blocks, solid blocks. The material is made of lightweight concrete, mixed with various industrial wastes and aerated concrete blocks, etc., such materials are more suitable for people's masonry habits, and the application is more convenient.

The second is lightweight boards, with large lightweight concrete slabs, and sandwich panels made of insulation materials. Some are made into various slats, and some are made into whole slats. There are various types of plates developed by related companies, and there are also sheet production lines imported from abroad.

Steel columns, steel beams, supports, purlins, pull strips, brace pipes, corner braces, door posts, door beams, etc.

It depends on whether you are asking about light steel or frame.

Generally, the main structure is steel columns and steel beams.

Metal structural components are divided into three categories:

1. Steel columns, roof trusses, bracket beams, windproof frames, ball node steel grids.

2. Crane beams, brake beams, steel purlins, steel supports, upper and lower gears, steel tie rod railings, cover plates, garbage ash doors, grates, ladders, sporadic blocking components, platforms, operating tables, walkways with type rest platforms, escalators, steel crane ladders, chimney fastening hoops, steel sheet piles, steel funnels.

3. Wall frames, wind shields, skylight frames, combined purlins, light roof trusses, rolling brackets, suspension brackets, pipe brackets.

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.

The steel structure is an overloaded steel component caused by the parallel connection of steel plates, cold-formed steel, and special steel through lap joints.

With light weight, industrial use, fast installation, short construction period, good seismic performance, fast investment, small environmental pollution of the comprehensive advantages, should be for reinforced cement construction, with "high, large, light" three ways to work special performance, in all parts of the world, especially in developed countries and regions, in the field of construction, steel structure is reasonable, widely used.

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.

<><1. What are the types of structures divided into steel structures?

It can be divided into frame structure, light steel structure, tower mast structure and cable membrane structure, etc., and the performance and load-bearing capacity of these structures are different, so in the construction process, more practical construction requirements are required to choose. In addition, for the steel structure, its own bearing capacity is very important, which is directly related to the overall safety of the project.

Second, the steel structure installation precautions

1. Strictly control the materials.

When installing the steel structure of the brother chain, the quality of the material is very important, and it must be controlled. Check whether its variety, model, specifications and other dusty aspects meet the design requirements, and randomly sample from the material for retest, and wait until the retest is qualified before it can be used. You can choose the matching electrode, welding wire and flux according to the steel grade, but all of them must be with a certificate.

2. Strictly control the quality of personnel.

When the steel structure is installed, in addition to paying attention to the quality of the material, it is also necessary to pay attention to the quality of the installer. For the installation of steel structures, welding, rivets and other aspects are generally used to connect, among which special types of work such as welders and crane workers must be strictly tested to ensure the safety of the operating system. At the same time, the certificate of the construction personnel must be tested to see whether it is issued by the issuing unit, whether its service life has expired, etc.

3. Pay attention to the connection of the steel structure.

In the process of steel structure installation, it is also necessary to pay attention to the connection, and the components or parts used in it are made of steel. When installing, it is necessary to pay attention to the quality of the connection, because if this aspect is not well controlled, it will directly affect the safety of the overall economic structure. To know the normal connection method selection and connection method, its reasonable design is an important part of the overall installation.

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.

3. The steel structure of the industrial plant is usually used as the load-bearing skeleton of the heavy workshop, such as the open-hearth furnace workshop, the initial rolling workshop, the mixed iron furnace workshop, the steel casting workshop, the hydraulic press workshop, the forging workshop of the heavy machinery factory, the slipway workshop of the shipbuilding fluid Qiaosong factory, the assembly workshop of the aircraft factory, and the roof and crane girder of other workshops with large spans. Many workshops of several well-known metallurgical joint ventures such as China Anshan Iron and Steel, WISCO, Baotou Steel, and Shanghai Baosteel have chosen various planned steel structure workshops, and the hydraulic press workshop of Shanghai Heavy Machinery Factory also has huge steel structure workshops.

4. Light steel structureLight steel structure usually refers to the structure welded by round steel, small angle steel, thin-walled steel or thin steel plate. The advantages of light steel structure are light weight, low cost, high degree of factory production, small on-site installation workload, fast construction speed, beautiful appearance, wide internal grip, high construction area and space utilization, and it is very competitive in the construction of shopping malls. In recent years, light steel structures have developed rapidly in China, and the scale of use has developed from industrial plants, small and medium-sized residences, stadium stands canopies, and small warehouses to residences and villas.
