Steel structure splicing includes splicing in the workshop and on-site. The splicing methods include welding and bolting. We should implement…
The Steel Structure Workshop building more and more used in modern industrial production. Some of the products produced by the manufacturers go directly to the market, but most of the products have stocks, which requires a particular inventory of the warehouse. The fundamental difference between the factory and warehouse buildings is not much, just one for production, one for storage. Nowadays, the use of the steel structure workshop is also more and more extensive, so how to build qualified steel structure workshop, we are ready to start from the various processes of Steel Structure Workshop Construction.
The processes of Steel Structure Workshop Building:
1. Design: design is the source of all working procedures, thoughtful design can make construction twice as fast, and only with the design scheme, construction personnel can have a direction.
2. Production: Production is following the design of the processing of steel components.
The Production Process
Steel plate cutting used to process steel components formally. The quality of the cut has a direct impact on the next process. If the cutting is not careful, it may cause the material to become a pile of scrap iron. Quality control is significant.
Steel plate cutting used to process steel components formally. The quality of the cut has a direct impact on the next process. If the cutting is not careful, it may cause the material to become a pile of scrap iron. Quality control is significant. The procedure belongs to the concealed engineering and is one of the most comfortable quality problems, so it is necessary to ensure enough welding strength to ensure the durability of the component.
The painting is also a hidden process, which has a significant impact on the service life of the steel structure building. The excellent coating can do the steel structure workshop for a long time will not rust, not easy to destroy, increase the service life of Steel Structure Buildings.
3.Installation: This working procedure plays an essential role in the engineering quality, and its quality greatly influenced by the above working process and the whole steel structure workshop.
The Installation Process
1) Hoisting of the main structure
Joint the roof steel beam on ground, install steel column, hoisting Steel Beam, connecting secondary structure, correcting main structure deviation, installing crane beam (optional), raising interlayer (optional), fireproof coating.
Main Control Quality: the main structure deviation should meet the specifications and design requirements, high-strength bolts should meet the needs of the steel structure workshop.
2) The installation of the secondary structure
Roof purlin, wall girt, fly bracing, wall and roof cross bracing, and so on.
3) The installation of the roof panel and insulation
First, lay the insulation layer, then install the roof panel (some projects in the insulation layer put the steel wire Mesh, to prevent the insulation layer fall off, this mainly depends on the insulation layer level)
The leading control quality: the roof is primarily waterproof, so to see the board and board lap joint, nail case, the glue coating is full, the glue place should be wiped clean, the plate surface coating should not destroy to prevent rust, etc.
4) The installation of the wall panel
It is the insulation and wall panel installation of the steel structure workshop.
Main Control Quality: There is also the problem of installation deviation, such as the bottom to flat, the whole plane to flat, plate, and plate between the flatness deviation to meet the requirements.
5) The installation of trim and flashing
The installation of trim and flashing, such as the corner trim between the roof and wall, corner trim of the wall, the flashing between the brick wall and wall panel, doors, and windows trim.
Why build the steel structure workshop?
It is necessary to choose the appropriate construction method to improve the quality and service life of the steel structure workshop. Especially for the load-bearing members of some steel structure workshop buildings, it is necessary not only to strengthen the quality control in the field construction process but also to adopt a scientific and practical design scheme, to ensure the structural stability and safety of the Steel Structure Workshop.
The construction time of the steel structure workshop is short, all steel components processed and prefabricated in the factory, and installed on the site, which saves time and labor cost.
It is a very reasonable choice to use steel structure to build the workshop building to save costs. The manufacture of the components of the Steel Structure Workshop can realize the industrialized production with high precision, and only need to transport to the construction site to install, the construction steps that need to process to the construction site are simplified. The constructors of the steel structure workshop should carefully examine the drawing requirements before installation, arrange the constructors reasonably, and provide a quality guarantee for the installation of the steel structure workshop.
But some problems with steel structure workshop also need attention, steel structure workshop long-term exposure in the air, natural to corrosion, weak fire resistance is worthy of consideration. In the chemical plant, the molecular activity of metallic materials is much more active than that of concrete materials, and it is easy to react with elements in the air to cause corrosion of steel structures. There are also precedents in fire resistance, and many building fires caused by the melting of steel in high temperatures. Steel structures are not fire-resistant. As the increase of heat, the yield point and strength of the steel structure will decrease. Thus the performance of steel structure workshops will also decrease and will collapse, so it is necessary to improve the anti-corrosion and fire resistance of the Steel Structure Workshop.
Single-story Steel Structure Workshop Building:
Single-storey Steel Structure Workshop building is an industrial factory building with one story and steel structure as the main body. Single-story steel structure workshops often used for large machinery and equipment or massive lifting transport equipment factories, such as metal and plastic, mechanical equipment, printing paper products, molds, and other industries. The Exterior Wall and the roofing part generally use the corrugated single color sheet.
The characteristic and application of steel workshop building:
Large span and space and various load forms, and often bear the dynamic load and moving load (such as crane load, power equipment load, etc.). The column is to carry roof load, wall load, crane load, and the seismic capacity of the main components; The requirement of geological exploration is higher. The single-story Steel Structure Workshop often uses the fitting structure standardization.
1) length: unlimited
2) Span: 12 ~ 50 meters clear span
3) Height: The drip water level of the single-story steel structure workshop is significant; some workshop height is 4-5 meters, some 6-7 meters, some can be as high as 11-12 meters or higher. Generally, the higher the steel structure workshop will be more difficult to build, the cost of materials required will be more expensive.
4) Internal structure: There is a bracket workshop to load the crane, this is an essential part of industrial production, many work machinery, and equipment and heavy production materials need the crane, so it must install the bracket and crane.
5) External structure: single layer color steel sheet and sandwich panel.
At present, the single-story Steel Structure Workshop is the primary type of workshop and warehouse in Metallurgy, machinery, and other industries. Many workshops choose a single-story steel structure workshop mainly because of its large span, and the height can adjust to the need.
Multi-story Steel Structure Workshop
Multi-story Steel Structure workshop building is another form of an industrial building with excellent development prospects. Generally, it refers to the industrial factory building, workshop, warehouse, etc. Below ten stories and less than 20 meters in height, most of the modern multi-story steel structure workshop constructed with the Portal Steel Frame Structure System.
When designing the layout, take note of the following technical points:
1. The multi-story Steel Structure Workshop Building generally adopts the frame structure system, also called a multi-story steel frame structure, which composed of the column, beam, floor structure, bracing structure, wall panel, or wall frame.
2. The rigid plane floor should adopt to ensure space integral rigidity and space coordinate work. When the transverse frame is the column-bracing system, and the space between columns is not more than 40m.
3. Reasonable arrangement of column distance and beam system, uniform LongitudinalLongitudinal and transverse stiffness, special force transmission, uniform type of members, simple joint structure, and easy construction.
4. The steel column and its bracing can change the cross-section along the vertical direction, but the sudden change of inter-story stiffness should prevent.
Structural combination type of multi-story Steel Structure Workshop:
(1) Steel frame system:
Rigid-jointed frame in both vertical and horizontal directions, which is suitable for buildings with large column spacing but no bracing.
(2) column-bracing system:
Beam-to-column are hinged joints, and column-to-column bracing (lateral resistance members) provided along with column height in both Longitudinal and transverse directions, save the quantity of steel.
(3) frame-bracing system
Longitudinal column-bracing system; lateral steel frame system, on the one hand, to meet the functional requirements of the building, on the other hand, to simplify the design, construction, reduce the amount of steel.
(4) frame-bracing composite system.
The floor forms of multi-story Steel Structure workshop are galvanized metal bearing plate, steel frame beam and precast cement plate, steel frame beam and pattern steel plate, steel frame beam, and wood plate.
