How To Meet The Quality Standard Of Reverse Hanging Tensile Fabric Structure?

In the process of making anti-hanging membranes, we must do well in every process. If we make a wrong step, it will affect the quality of the anti-hanging membrane project.  So what should we do to meet the reverse hanging tensile fabric structure quality standards?  First, we need to meet the following five conditions.

1. Selection of membrane materials and components

The quality of the membrane material is very important for a membrane structure project. Even if it is the same membrane material, the quality of different manufacturers, different models, and even different production batches also have differences. The local quality defects of the wood should be skipped when cutting the material. In addition, the membrane structure using metal components should take effective corrosion protection measures. When designing, the size of the cross-section of the component should be selected to allow for the influence of corrosion. Use components made of stainless steel as much as possible.

2. Prevent damage to the connecting members

The connecting member is also an important factor in the tension of the membrane structure. The design of the connecting member ensures that it meets the requirements of mechanical strength and has an appropriate safety reserve. The key parts can be considered to set up safety chains and other structural measures, in case the damage of the connecting parts will not endanger the safety of the entire structure.

3. Avoid membrane damage and tear deformation

When designing the membrane structure, it should be ensured that the membrane surface has sufficient rigidity after tension. The detail structure design should take into account the possibility of secondary tension, and the secondary tension should be timely performed on the slack membrane surface. The design of the joints must ensure sufficient freedom of rotation to accommodate the tearing or deformation of the membrane surface under the action of wind.

4. Prevent membrane area water

When designing the shape of the membrane surface, a larger slope of the membrane surface should be used and the drainage path of the membrane surface should be convenient. Apply the corresponding vertical load on the membrane surface according to the rainfall situation at the project site, and check the contour map of the deformed membrane surface. If there is an approximately circular or elliptical area outside the high point, the shape of the membrane surface should be modified. During tension, the pretension of the membrane surface must reach the designed pretension level. The slack membrane surface should be re-tensioned in time, and the water situation of the membrane area should be promptly assisted by drainage in time, and corresponding remedial and modification measures should be taken.

5. Prevent fire damage

The membrane surface of the membrane structure should minimize the proximity of combustible objects. Corresponding fire-fighting facilities shall be set up strictly in accordance with the requirements of building design fire codes.
