Prefabricated steel structure workshop
The prefabricated steel structure workshop building is used for industrial production, where all steel structures need to be painted and then delivered to the project site for installation. And because the steel structure can be manufactured in the factory and installed on site, construction time is greatly reduced. Due to the use of steel, construction waste can be greatly reduced and more environmentally friendly. Therefore, it is widely used in industrial buildings and civil buildings.

(1). The composition of the prefabricated steel structure workshop:
Column and top beam steel structure workshop
The columns and top beams are usually assembled and welded with hot-rolled H-section steel or steel plate. The manufacturing precision of H-shaped steel made of hot-rolled steel is easy to control. The column welded by steel plate needs to be corrected after assembly and welding, which can prevent the H-shaped steel from deforming due to welding deformation.
Second frame
1. Pur strip: Pur strip is made of C-shaped and Z-shaped steel.
The bars are used to support the roof and wall panels and transfer the load from the roof and wall panels to the main steel frame.
2. Support frame
There are roof support frames and wall support frames. The support is usually made of steel rod, L angle or square tube. The support system is used to stabilize the steel frame.
3.
The pendant rod is used to connect the two purlins to adjust and control the stability of the two adjacent purlins. Generally, the pendant rod is made of a rod with a diameter of 12 or 14 mm.
(2). Structure type:
Door frame steel frame
The mast is a traditional structural system. The upper main frame of the structure type includes rigid frame beams and columns, supports, purlins, tie rods, wall enclosures, etc.
. The steel portal frame is a branch of light steel structure.
Structural features:
1). It reflects the characteristics of light weight, speed and efficiency of light steel structure. It uses new energy-saving and environmentally-friendly building materials.
2). Realize factory processing and production, on-site construction and assembly. Convenient and fast, saving construction period.
3). The structure is firm and durable, the price is reasonable, and the economic benefits are obvious.
4). The size of the column distance is free and flexible. It can meet the construction and use requirements under different climate and environmental conditions.
The main application scope of steel structure door frame includes steel structure workshop, metal warehouse construction, industrial shed, aircraft hangar, etc.
(3). Enclosure structure prefabricated steel structure factory building
There are two types of wall panels and roof panels: corrugated monochromatic panels and sandwich panels.
Monochrome metal panels are used in buildings that do not require heat preservation and heat insulation.
Sandwich panels are mainly used in buildings that require thermal insulation. The core materials of sandwich panels include foam, glass wool, rock wool and polyurethane.
The other is corrugated monochrome paper mixed with glass wool rolls on site.
The role of roof and wall enclosure structure:
1) Purlins and ring frames are essential frames. They are combined with metal cladding to form roofs and walls.
2) Transmit horizontal force together with the supporting system and stabilize the entire building.
(4). P strip and wall decoration
The main types of bars and enclosures are C-type or Z-type, and the section size should be determined after force calculation.
Compared with the Z-shaped cross section, the mechanical properties of the C type are very different. Z-shaped purlins are erected overlappingly, so they are continuous beams.
The maximum distance between the strip and the wall ring should not exceed 1.5 meters.
(5). Process of prefabricated steel structure workshop
1). design:
Design is the source of all programs. Smart design can not only save costs, but also make construction smoother.
2). produce:
Production is an integral part of the steel structure workshop manufactured according to the design plan. It includes the following steps.
(1) Cutting.
This process is used for the formal processing of steel components. The cutting quality directly affects the next process. If the cutting is incorrect, the material may become scrap iron. Therefore, it is essential to strengthen the quality control of the process.
(2) Production.
This is one of the most prone to quality problems. Therefore, sufficient welding strength must be applied to ensure the durability of the component.
(3) Painting.
This process has a significant impact on the service life of steel structures. A good coating can prevent rust and corrosion of the steel structure for a long time, thereby prolonging the service life of the steel structure warehouse.
4). On-site installation:
This process occupies a vital position in the quality of the project and has a greater impact on the entire steel structure warehouse.
(6). Advantages of prefabricated steel structure workshop:
1). Light weight and high strength.
The prefabricated steel warehouse occupies only 1/2 of the weight of the reinforced concrete building, which can meet the needs of ample space. There are no chromatographic column obstacles inside, the clear span is large, and the internal space is large.
2). Environmental protection.
Steel structure materials can be recycled and used to reduce pollution during construction and demolition.
3). Quick installation:
The construction time of the steel structure warehouse is short. Since the components are prefabricated in the factory, they only need to be assembled on site. Greatly shorten the construction period.
4). performance:
The prefabricated steel warehouse is durable, easy to repair and simple to maintain.
5). Exterior:
The steel structure workshop is beautiful and practical, with simple and smooth lines. Color wall panels come in various colors, and walls can also be used for other materials. Therefore it is more flexible.
6). Lower cost:
The steel structure warehouse cost is reasonable. Lightweight components can reduce the value of the foundation.
