Membrane structure landscape It is a new landscape form, which uses tensioned membrane materials to form a structural form with landscape modeling, which can be said to be a complete combination of architecture and art. Because membrane structure has not been popular in China for a long time, membrane structure landscape is also unfamiliar to many people. Compared with traditional landscape facilities, membrane structure landscape can not only provide very good viewing, Moreover, it is highly practical, most of which can be used as sunshades, and its rich shapes can be integrated with the surrounding environment. In addition, because of the unique color rendering of the film itself, it can produce colorful effects against the background of night lights. It is precisely because the film structure landscape has so many advantages, its application is gradually increasing, With its lively and vivid shape, it shows the charm of membrane structure, a new architectural form.

With the continuous increase of membrane structure landscape, a problem arises that is how to properly maintain it. Today, I will introduce the six major maintenance measures for the lower membrane structure landscape.

1. Cleaning

The accumulation of dirt on the membrane surface of the membrane structure landscape is related to the local environmental conditions, the characteristics of membrane materials and the shape of the landscape. From a technical point of view, the membrane structure landscape does not necessarily need cleaning. For most membrane materials, cleaning cannot extend their service life. On the contrary, improper cleaning will shorten their service life.

2. Patching

If minor damage occurs to the membrane surface due to accidents during the installation of membrane structure landscape, on-site repair can be carried out at this time. After being put into use, the fiber cloth and coating of the membrane cloth base course should be checked regularly. For small cracks or damages with a length of less than 5cm, the damaged part can be repaired directly by welding patches.

3. Corrosion

The anti-corrosion measures and materials shall be selected according to the local environment, and the corrosion of supporting structures, cables (especially those deep into the fixed end), splints and bolted connections shall be checked regularly. In case of corrosion, the corrosion layer shall be removed first, and then the anti-corrosion treatment of the surface shall be done again. If the bolted connection is corroded, it shall be replaced.

4. Replace

Keep all the working drawings and construction drawings throughout the service life of the membrane structure landscape, which can make the replacement of the landscape membrane very simple. When replacing the membrane cloth, the test should be repeated to determine its compensation value. If the film material of the original width is out of stock, it needs to be cut again. It may also be necessary to re form the structure according to the specific dimensions of the existing support structure.

5. Ponding and drainage

Due to the deformation of membrane materials of membrane structure landscape under load, there may be ponding at the place with small slope of membrane surface. After heavy rain or snow and snow melting, the membrane structure landscape should be checked to avoid water accumulation.

6. Secondary tensioning

The stability of membrane structure landscape depends on the maintenance of membrane surface pretension. The pretension affects the deformation of the membrane under load. If the pretension is too small, the membrane will have large deformation and flutter under the action of wind load. If the load lasts for a long time, the membrane material will relax and creep, so the prestress of membrane surface will change during use. The performance of membrane material for membrane structure landscape can be determined through biaxial test. If the pretension is too low, it needs to be re tensioned to restore its prestress.
