Air membrane manufacturers in the inflatable membrane project before the official entry, in addition to the need to complete the construction site of the pre-foundation of the civil engineering work, but also in the factory in advance of the processing of air membrane membrane membrane material. The main processing process of the air membrane manufacturer is cutting and joining.
There are three main ways to connect between the diaphragms of the air membrane manufacturers: heat bonding, sewing or mechanical connection. The part of the joint between the membrane and the membrane should be decided comprehensively according to the architectural requirements, structural requirements, economic requirements and other factors.
The connection points of membrane material are as follows:
1, cut membrane material connection to maintain a high degree of watertightness, should be anti-peeling test. Membrane should be tile-like arrangement, by the high membrane to cover the low membrane.
2、The membrane material of the air membrane pavilion must consider the influence of pre-tension stress in the cutting, and decide the shrinkage of the membrane sheet according to the strain relationship of the membrane material, and adjust the size of the membrane sheet.
3, cutting and sewing should consider the orthogonal anisotropy of the mechanical properties of the membrane material, it is desirable to make the main stress direction of the structure is consistent with the fabric fibre.
4、The connection node of membrane material contains membrane sheet and membrane sheet connection node and membrane surface and support structure connection node. According to the different support system, it can be divided into membrane surface and flexible support structure node and membrane surface and rigid support structure node, and the connection part is different, it can be divided into middle node and boundary node.
5、The connection structure of air membrane building membrane should consider the shape of the structure, load, manufacture, installation and other conditions, so as to make the structure safe, reliable, ensure the transmission of force, and can adapt to the possible displacement and rotation.
6, the membrane surface and support structure connection node must have enough strength and rigidity, shall not be connected before the members and membrane material and damage, also should not form a deformation that affects the performance of the force.
7, the air membrane pavilion diaphragm connection should maintain a high degree of watertightness, should be anti-peeling test, and should avoid fabric abrasion, tearing. Connection of the metal components should be to avoid corrosion measures. Connection components should give full consideration to the impact of membrane creep.
