Protection and protection of membrane structure engineering. The surface of the membrane material shall not be touched by knives and sharp tools to avoid scratching and abrading the surface of the membrane material. Once the membrane material is found to be scratched, severely abraded and other phenomena, effective measures shall be taken in time to prevent the abrasion from becoming more severe, and the manufacturer shall be informed to send someone to correct it. The steel component shall not be hit and scratched by hard objects, and shall not touch various acidic, alkaline and organic solvents.
As we all know, membrane structure is significantly different from other construction materials. Membrane structure is the data with popular elements in the construction industry. Membrane structure scene The changeable supporting structures and flexible membrane materials of manufacturers make the building more novel and beautiful, showing the cultural characteristics of the city and representing the trend of the times. Membrane structure has outstanding optical performance, acoustic performance and good fire resistance. Membrane structure landscape
The weather resistance of membrane structure refers to the characteristics that the appearance color, brightness and strength of membrane material, as a construction covering system, will gradually deteriorate with the extension of time under the effects of natural environment such as sunlight, temperature change, rain wash and dust erosion.
The external coating materials of the membrane materials PTFE or PVDF are inert materials, which have chemical properties such as UV resistance, aging resistance, corrosion resistance, etc., and have greater advantages than PVC coatings. Generally speaking, the service life of PTFE coated membrane is more than 25 years, and the service life of PVC membrane coated with PVDF surface layer is 10-15 years, which makes the membrane widely used in durable construction.
The membrane structure belongs to the modern construction, which can build a landmark image project, and has the use of practicality and appearance. It has a wide range of applications around the world. It also reflects a new style of construction, and has its beautiful curve shape. It is said to achieve the representativeness of modern construction, with a new sense of vision. However, the membrane structure can be used in parking lots, garages, station facilities and leisure facilities. In particular, it has a wide range of applications, and each has its own advantages. As a scene film structure shed, we can share its advantages.
The steel structure planning part of the membrane structure shall meet the requirements of the steel structure planning specification and other relevant regulations.
The internal force and displacement of the membrane structure under the effect of external load shall be calculated, and the internal force and displacement under the effect of temperature change, bearing settlement and construction device load shall be calculated according to the specific situation. For membrane structure accounting, several nonlinear effects shall be considered according to its characteristics of large deformation, and the data nature can be considered as linear. The cable and membrane in the membrane structure can only bear the tension, but cannot bear the pressure and bending moment. During the planning, it is necessary to avoid the occurrence of cable membrane looseness under normal operation. In the planning, it shall be ensured that the stress of the membrane data under the load effect shall not be greater than the allowable stress of the data. Load and load effect combination The load and load effect combination of the steel structure planning part of the membrane structure shall be calculated in accordance with the Load Code for Building Structures. The dead load, roof live load, wind load, snow load and initial pretension shall be considered for the load acting on the membrane structure. The load standard value shall be taken in accordance with the relevant provisions in the Load Code for Building Structures.
