People in the appreciation of the membrane structure of the building often marvel at their magnificent, and see the film structure of the sketch will be their dexterity, flowing deeply attracted. But in the actual construction, whether it is tens of thousands of square meters of large-scale membrane structure, or a few square meters of membrane structure, are not only a piece of film, but by a lot of diaphragm splicing.

Commonly used membrane structure membrane material welding method has hot gas welding, heating unit welding and high-frequency welding, and welding joints are constructed in the following ways:

1, the same material and thickness of the diaphragm single-sided welding, or the use of poor coverage diaphragm double-sided welding.

2, double-sided covering diaphragm staggered into a thicker contact. The staggered junction can reduce the discontinuity of load transmission.

3, using the shape of the same material and thickness of the diaphragm, but will cover the diaphragm into two semi-double-sided welding, so that the load can be smoothly transferred.

4,The link length of the transfer load can be increased by cutting the membrane structure diaphragm into a tooth shape.

5, high-strength double-layer membrane materials can be used in the double-sided staggered coating of the method to form a thicker contact.
