Daily maintenance knowledge of membrane structure engineering
Membrane structure should be checked regularly to see if it is in normal working condition. The main inspection items are: whether the membrane has large deformation, whether the membrane is relaxed due to the loss of pre-tension, whether the membrane is partially torn, whether the membrane coating is peeled off, whether the cable is loose, whether the paint is peeled off, etc. Check sub item as follows:

Membrane maintenance |
|
|
|
1.Check and clear the leaves and debris on the top of the membrane structure at least three times a year, especially after typhoon weather. 2.Membrane structure surface can be superficial, but no sharp objects can contact the surface of the membrane, nor can shoes walk on the surface of the membrane to prevent wear and tear of the protective layer on the surface of the membrane. 3.It is forbidden to use strong detergents such as Tiannashui for cleaning membrane surface at least once a year. It is advisable to use relatively mild detergent or detergent after dilution. It is also forbidden to use steel brush for surface cleaning. Plastic brush or cloth strip should be used for cleaning to avoid damaging membrane surface. 4.Membranes belong to non-combustible materials, but when exposed to open fire, they will melt. Therefore, high temperature materials such as fireworks and welding should be avoided. 5.Membranes have certain elasticity and tensile strength, but falling objects from high altitude should be avoided, especially sharp glass, iron, stone, brick and so on. 6.Membrane surface becomes very wet and slippery when there is water. It is necessary to pay strict attention to safety, buckle the safety belt and do a good job of safety protection measures when working on it. |

Maintenance of steel structure |

|
|
1.After the project is delivered to use, the owner can not change the structure without authorization, and can not disassemble any bolt components. If you need to change, please contact our company after stress assessment before changing. 2.Steel structural members should be repaired once a year to extend the overall appearance and service life of steel structural buildings. 3.Owners should install electric lighting equipment. Wires can not be directly tied to steel members. Pipes or grooves should be installed in isolation to avoid electric shock. When cleaning the surface of steel structure, there should be no scratching phenomenon, so as to avoid using bleaching ingredients, washing articles containing abrasive and acid liquid to wash, steel ball and wear-resistant products should not be used, and clean water should be used to wash from top to bottom. 4.If there are technical problems that the owner can not solve by himself in the later use of the steel structure, we must contact our company and never refit the steel structure by ourselves. |
