What are the regulatory requirements for membrane structure engineering construction and installation?

Membrane structure engineering is increasingly appearing in our lives, because of popularity, quality and cost performance, so it is very popular. Although the membrane structure has many advantages, when the engineering components are processed and installed, there will still be many problems. And then membrane structure engineering buildings need to pay attention to and comply with the specifications during processing and installation, let us look at it.

The production and installation of the membrane structure shall be divided into one or several inspection and approval according to the specific conditions, and the quality of the project shall be checked according to the corresponding rules.  The inspection of the steel structure sub-project related to the membrane structure processing and installation shall be carried out in accordance with the current national standard "Steel Structure Engineering Construction Quality Inspection Plan" GB-50205.  Other inspections related to sub-projects shall be carried out in accordance with the relevant construction quality inspection specifications.

The support structure and the joint structure of the membrane structure shall comply with the following specifications:

1. Ensure the safety, reasonableness and beauty of the connection.

2. At the same time, the joints should have sufficient strength, rigidity and durability.

3. The transmission force of the joints should be firm and reduce the stress concentration at the joints.

4. the node structure should consider the impact of eccentricity on the cable, the film, the method of applying pre-tension, reduce the error in the installation of the structure, and the possibility of secondary tension.

5. Adhere to the high degree of tightness at the joint of the membrane, adopt a fixed construction method to avoid abrasion and cracking of the membrane.

6. Reliable anti-corrosion measures should be adopted for metal joints.

7. There must be no burrs, sharp corners, sharp points, etc. at the joint between the support member and the membrane.

The appearance of the film surface should be fully viewed:

1. Membrane drainage slope, drainage trough, gutter, cornice and other practices should meet the planning requirements.

2. The appearance should be no water puddle, you can use natural or artificial water spray experiments to see if the drainage is smooth.

3 .The appearance of the membrane surface should be fully inspected, should be kept free of stains, cross-color phenomenon, no damage, scratches, no wrinkles.

4. After the project is completed, it is necessary to check whether the tension value of the membrane surface meets the planning and pre-tension.

The membrane structure engineering inspection, should have the following documents and records, and check the quality requirements of the relevant rules:

1. Membrane structure (including steel and cable structure) construction drawings, as-built drawings, and planning change documents.

2. Construction organization planning.

3. Product quality assurance and inspection statements for membranes, steel, cables and their materials.

4. Quality inspection records for the manufacturing process of membrane units, steel components, cables and other components.

5. Membrane unit device and quality inspection record for pre-tensioning process.

6. Professional operation personnel certificate.

7. Other related documents and records.

Membrane structure is a very important technology in our life. The use of membrane structure will be more and more popular. In the future, with the advancement of science and technology and the high development of technical, membrane structure will be more satisfied. The detection of membrane structural engineering will be more important. It is also important to choose a good membrane structure company. Wanhao with the domestic first-class membrane structure enterprise are worthy of your trust.
