The service life of the membrane structure is about 15 - 30 years. For the longer service life and lower damage degree of membrane structure, Shenzhen Sigma membrane structure Import and Export CO., LTD. provides its own guidance for the daily maintenance of membrane structure users.
Membrane structure products have been popularized and applied as new materials and new buildings. Membrane materials with special surface treatment have long service life and good self-cleaning properties, which makes membrane structure buildings different from common ordinary buildings. Meanwhile, its simple and elegant characteristics are also become more and more popular.
1. Drainage and Ponding of Membrane Structures:
Due to the deformation of membrane structure under load, there may be accumulated water at the place where the slope of membrane surface of membrane structure is small. After heavy rain or snowfall and melting of snow, the tensile membrane structure should be monitored to avoid water accumulation.
2. Membrane Structure Cleaning:
The accumulation of dirt on the membrane surface of membrane structure is related to local environmental conditions, membrane material characteristics and the shape of membrane surface. From a technical point of view, the membrane structure does not necessarily need cleaning.For most membrane structures, cleaning cannot prolong their working life. On the contrary, improper cleaning can also shorten their life.
3. Replacement of membrane structure:
Keeping all the processing drawings for the entire service life of the membrane structure can make the replacement of membrane structure membrane very simple.However,the new membrane structure adopted should be retested to determine its compensation value. If the membrane structure with the original width is out of stock, the cutting design should be redesigned. It may also be necessary to re-shape the structure according to the specific size of the existing support membrane structure.
4. Corrosion of Membrane Structures:
Anti-corrosion measures and materials should be selected according to the site environment. Regularly check the corrosion of the support structure, cables ( especially those deep into the fixed end ), clamping plates, bolt connections, etc. If corrosion occurs, the corrosion layer should be removed first, and then the surface should be re - treated. If the bolt connection is corroded, it should be replaced.
5.Service temperature:
The temperature of this product is - 40 ℃ / + 70 ℃. When setting up lighting and heating equipment, it should not be too close to the membrane material to avoid burning the membrane material.
6.Prestressed and Secondary Tensioning of Membrane Structures
The stability of membrane structure depends on the maintenance of prestress in the membrane. The level of prestress affects the deformation of the membrane under load. If the prestress is too low, the membrane will produce large displacement and flutter under the action of wind.
Because the membrane material of membrane structure will produce relaxation and creep under the continuous action of load, the prestress in membrane will change during use. The performance of membrane structures for specific structures can be determined by biaxial tests and applied to prestressed design.
7.Repair of Membrane Structure
The tensile membrane structure will cause little damage to the membrane surface of the membrane structure intentionally or unintentionally during installation. At this time, it can be repaired on site. The base fabric and coating should be inspected regularly. Small cracks or small holes less than 5 cm in length can be repaired directly by welding patches on the membrane surface of the membrane structure. The patches must be rounded.
