The same weld should be welded continuously at one time, if it cannot be completed at one time, it should be preheated before welding.
In recent years, long-span structures have been widely used not only in sports buildings, but also in various commercial buildings (such as supermarkets, warehouses and warehouses), and the application of long-span structures in building structures in China is also increasing.
The construction method of the space frame has full scaffolding aerial bulk method, aerial picking method, ground assembly overall lifting method, etc.. Construction methods are diverse and flexible：one construction method can be used alone, or a variety of construction methods can be mixed, and the environmental requirements for the construction site are not too high. Most of the steel structures are prefabricated in factories, assembled on site, and installed by the whole crane, which must have the cooperation of cranes in construction and have high requirements for the site.
The design of membrane structure mainly includes body shape design, initial equilibrium shape analysis, load analysis and shearing analysis. The body design is used to determine the building plane shape and size, three-dimensional shape, headroom volume, coordinates of each control point, structure type, and selection of suitable membrane materials and construction plan.
The basic function of the gas station canopy is to shelter personnel, vehicles and fuel dispensers from the wind and rain, and it is also an important part of the overall image of the gas station, and even the most important image recognition mark of the gas station.
The joint workshop of Xuchang cigarette factory is a comprehensive tobacco joint production plant consisting of more than thirty different functional rooms, such as formula elevated warehouse, silk making workshop, vacuum damp room, pre-matching cabinet room, etc.
The diversification of buildings requires solid and reliable technology in the connection of steel structures. Steel structure welding and strength bolt construction are the main methods of steel structure connection, with high efficiency and high performance. Good, safe and reliable, it has been widely used in construction with good results.
Due to the large single area and large span of the roof, and the steel space frame roof structure , there are many cranes running in the factory building , and the vibration is relatively large , so that the roof is in the process of elastic changes , and the design and construction of the roof waterproofing project are difficult.
In recent years, as a relatively new form of coal storage, the circular stockyard has been promoted and applied in the domestic coal storage and blending industry. It has outstanding environmental protection effects, beautiful appearance, high site utilization rate, and high degree of automation, especially in coastal climates. Reliable use in harsh areas.
The components of the steel structure are composed of section steel, steel plates, etc. through connection, and each component is then installed with a connecting frame to form the entire structure. When designing the connection, the principles of safety and reliability, clear force transmission, simple structure, convenient manufacture and saving steel must be followed.
With the improvement of national environmental protection requirements in recent years, factories and mines are required to be closed for production. The steel structure space frame with large span and large space is light in weight, good in integrity, large in space rigidity, good in seismic performance, and can save steel, Advantages such as fast construction speed are applied to newly built industrial plants.
Light steel structure has become an indispensable technical means in the construction of industrial buildings, and has become an inevitable demand for the further development and application of subsequent construction technology.
