With the gradual advancement of the definition of green environmental protection, new environmentally friendly materials with low energy consumption and high efficiency have rapidly captured the home building materials market, and the use of steel frame structures has become more and more common, especially in factory buildings. In order to better ensure its effectiveness, the design of steel structure engineering construction plant must be based on specific requirements and continuously improve the steel structure plan of the industrial plant, thereby improving the safety factor and reliability of the steel structure plant. Based on this, the article discusses the advantages and design features of steel structure factory buildings, and discusses and analyzes the key points of the steel structure factory building design.

1. Analysis of key points of steel structure factory building facade design plan

There are four basic characteristics in the facade design of steel structure factory buildings: scale, line, color, and transformation. Comparing the steel structure factory building and the concrete structure industrial factory building, the wire frame is the most distinctive feature of the light steel structure building type. Traditional concrete factory buildings have unsatisfactory lighting effects due to the flat roof. When designing, a large number of light windows are usually designed, and a large number of light windows will destroy the wire frame design of the wall. Steel structure factory buildings Not easily confused by this. Light steel structure flat roofs often use flat roof lighting tiles, which not only provide uniform illumination, but also do not damage the wire frame design of the wall. It is both practical and beautiful. It is currently particularly suitable for combined industrial plants, and it also solves the problem of industrial plants. natural ventilation problems. The facade design of the steel structure factory building is mainly determined by the process layout. The facade requires simplicity and grandeur, while being simple and unified to highlight the theme.

2. Analysis of the design scheme of lattice columns for steel structure factory buildings

Lattice columns are column forms that use connecting pieces to piece together channel steel limbs to form a unified whole. On the overall page of the lattice column, both the bending moment and the load are converted into longitudinal loads. This longitudinal load mainly acts on the lattice columns, and the main amplitude is borne by the supports of the lattice columns. The shear stress is dispersed to the strips or panels and is borne by them. The measurement method of lattice columns has unique lattice characteristics, which are specifically reflected in: the slenderness ratio of the lattice columns around the imaginary axis using the method of calculating the slenderness ratio; the axial force-bearing lattice structure that is bent tightly around the imaginary axis For columns, the overall reliability check within the bending moment function plan must be carried out; for the branch reliability check of lattice columns, a single limb stability check must be carried out according to the worst load of each branch; for the calculation of lattice columns Trims must also be included; lattice column design The design of unique connection points is also included in the overall calculation and partial design.

3. Analysis of the design plan of the transverse frame at the top of the steel structure factory building

1. Steel structure factory building endurance management system

The main components of the steel structure factory building include formwork support system, rack structure system, frame structure system, roof truss structure system, etc.

The formwork support system is mainly composed of column supports and roof truss supports. The function of the formwork support system is to connect the horizontal and vertical plan frames, making each part form a unified overall spatial layout, interconnecting, interacting, and coordinating work, so as to ensure the reliability and bending of the steel structure factory building. Stiffness.

In order to ensure a normal and safe working environment in the factory, the racking structure system forms a system that bears and transmits the weight of the building envelope through raft foundations, beams, walls, wind-resistant columns, etc. Wind load, wind load acts on the wall.

The frame structure management system consists of horizontal plan and vertical plan frames. As the basic load-bearing structure of the steel structure factory building, the horizontal floor plan frame is very important. It is composed of foundation, steel roof truss and horizontal columns. When establishing the connection between the flat roof beam and the column top, rigid connection or fixed connection can be used. Most of the connections between column sections and basic parts can only be rigidly connected. The components of the longitudinal plan frame are much more complicated than the horizontal plan frame. Its components include longitudinal columns, foundations, connecting beams, column supports, fixed brackets, crane beams, etc., which mainly bear longitudinal wind loads, longitudinal Temperature geostress, longitudinal seismic interaction force and crane longitudinal leveling force, etc. It is also indispensable for its function in steel structure factory buildings.

The roof truss structure system includes everything needed for the steel structure factory roof, such as roof, roof truss support points, gutter plates, fixed brackets, steel purlins, flat roof beams, etc.

2. Transverse plan frame load of steel structure factory building

According to the basic calculation method, the steel structure factory building design should take the overall spatial layout composed of the horizontal plan frame and the longitudinal plan frame as the calculation target. However, this calculation method is more complicated and the workload is extremely huge, so in the actual In calculation work, the load borne by the horizontal plan frame and the load borne by the longitudinal plan frame are generally measured separately. The workload of this calculation method is relatively small, and the results obtained are also relatively consistent with the actual data.

This is how the transverse plan frame plays a role in the steel structure factory building: it bears all the lateral and longitudinal loads inside the factory building. The basic modules of the steel structure factory building are determined through the horizontal horizontal frame design, and then the basic modules of the steel structure factory building are determined according to the crane beams and other various components. Various prefabricated components connect the horizontal horizontal frames to each other to form a three-dimensional spatial structure. This ensures that the longitudinal bending stiffness of the industrial factory frame meets the load-bearing requirements of the steel structure factory. In the design method of the transverse frame of the steel structure factory building, the load calculation for the transverse frame only includes the bearing capacity of the transverse plan, but the longitudinal wind load is not taken into account. However, in actual work, longitudinal wind loads are only considered in the design of longitudinal support points. However, in fact, while the transversely structured frame is subjected to transverse wind loads, longitudinal wind loads will also affect it. Therefore, in the design of the transverse plan frame of the steel structure factory building, the plan external bending moment caused by the longitudinal wind load should also be added.

3. Analysis of key points of temperature deformation joint design plan

Temperature will cause deformation of steel structure factory buildings, causing temperature stress in the structure. When the factory area is large enough and the temperature stress is large enough, the steel structure factory will undergo large deformation, causing risks. In order to better prevent such risks, temperature deformation joints are set in the factory. is indispensable. There are two settings for temperature deformation joints: one is the horizontal temperature setting joint, and the other is the longitudinal temperature setting joint. Which setting to choose depends on the actual factory design conditions. The setting of temperature joints divides the industrial plant into several temperature sections, and the steel structure standard determines the length of each temperature section. There are two ways to solve the temperature deformation joints, namely the single column setting method and the cantilever setting method. The former one is generally chosen to solve. If a longitudinal temperature deformation joint is set, a flip rubber bearing can be set at the rubber bearing of the steel roof truss. If a transverse temperature deformation joint is set, rough steel can be used at the connection between the frame beam and the steel purlin. Straightening splint dragging method or oval hole dragging method.

In general, the effective design of a steel structure factory building is related to its quality and operational effects after completion, and plays an important role in the safe use of the factory building. Therefore, during the design process of steel structure factory buildings, it is necessary to conduct a comprehensive analysis of the project to ensure the safe use of steel structure factory buildings.
