Prefabricated Steel Structure Production Workshop Steel Structure Warehouse

1. Analysis of facade design points of steel structure workshop.There are four basic characteristics in the facade design of steel structure workshop: scale, line, color and change.Compared with the steel structure factory building and the reinforced concrete structure factory building, the line is the most unique feature of the light steel structure architectural style.Due to the unsatisfactory lighting effect of the roof setting, a large number of lighting Windows are usually designed in the design of the traditional reinforced concrete structure factory building. However, a large number of lighting Windows will destroy the line shape of the wall, and the steel structure factory building will not be troubled by this.Light steel structure roof is a large number of use of roof light plate, not only uniform lighting, and will not destroy the wall line modeling, both applicable and beautiful, is very suitable for the joint type of factory buildings, incidentally also solved the problem of ventilation plant.The facade design of steel structure factory building is mainly decided by the process layout. The facade requires simple and grand, and at the same time, it is simple and unified and highlights the key points.

2. Design and analysis of lattice column of steel structure factory building.Lattice column is a column form which forms a unified whole by joining steel parts together.On the overall interface of the lattice column, both the bending moment and the axial force are transformed into the vertical axial force, which mainly acts on the lattice column, and the main force is assumed by the split limbs of the lattice column.The shear force is distributed to the straps or slabs and is borne by them.The calculation method of lattice column has its own characteristics, which are mainly shown in the following aspects: the slender-to-slender-to-ratio of lattice column around imaginary axis is converted;For the eccentrically compressed lattice columns bending around the imaginary axis, the global stability of the bending moment acting plane needs to be checked.The stability checking of the sublimb of the lattice column is carried out according to the most unfavorable axial force of each sublimb.The calculation of lattice column also needs to include fixture;The design of lattice column for special node design, also included in the overall calculation and local design and so on.

3. Design and analysis of the transverse frame at the top of the steel structure workshop.

1) Stress system of steel structure workshop.The components of steel structure factory building mainly include support system, envelope structure system, frame structure system, roof structure system and so on.The support system is mainly composed of two aspects: the column support and the roof support.The role of the support system is to connect the horizontal and longitudinal plane frame, so that each part becomes a unified overall space structure, mutual connection, interaction, collaborative work, in order to ensure the stability and stiffness of the steel structure plant.Enclosure structure system in order to ensure a normal and safe production environment in the plant, it through the foundation beam, wall beam, external wall, wind column and other components of a bear and transfer the weight of the wall of the wind load, the wind load acting on the wall.The frame structure system is composed of transverse plane and longitudinal plane frames.As the basic load-bearing structure of steel structure factory building, the horizontal plane frame is very important. It is composed of foundation, roof truss and horizontal column.The connection between the roof beam and the column top can be rigid or hinged.The connection between column segment and foundation can only be used in the form of rigid connection.The component of the longitudinal plane frame is more complex than the horizontal plane frame. Its components include longitudinal column, foundation, connecting beam, column support, bracket, crane beam and so on. It mainly bears the longitudinal wind load, longitudinal temperature stress, longitudinal seismic force and the longitudinal horizontal braking force of the crane and so on.It is also essential for the steel structure plant.The roof structure system includes everything needed for the roof of the steel structure workshop, such as roof panels, roof supports, gutter plates, brackets, purlins, roof beams and so on.

2) Transverse plane frame load of steel structure workshop.Steel structure workshop design according to the conventional calculation method, should be in horizontal plane frame and longitudinal plane frame structures, and the whole space structure as object of calculation, but in this kind of calculation is more complex, the workload is very large, so in the calculation of actual work, usually calculated separately by the transverse plane framework under the load and vertical plane frame on the load, the calculation of the workload is relatively small, the results are in conformity with the actual data is.Transverse plane frame in steel structure workshop is works like this: it has suffered internal plant all horizontal and vertical loads, through transverse frame design to determine the level of basic unit of the steel structure factory building, and then through the crane beam and other artifacts to lateral horizontal framework to connect, making it a space structure, to ensure that the skeleton of the longitudinal stiffness in steel structure factory bearing requirements.In the design method of the transverse frame of a steel structure factory building, the load calculation of the transverse frame only includes the bearing force of the transverse plane, while the longitudinal wind load is not considered.However, in the actual work, the longitudinal wind load is only considered in the design of longitudinal support, but in fact, the framework of the transverse structure is affected by the transverse wind load while the longitudinal wind load will also have an impact on it.Therefore, in the transverse plane frame design of steel structure factory building, the plane external bending moment caused by longitudinal wind load should also be added.
