The content and process of film layout cutting planning are as follows:
(1) Arrange cutting lines on the space film surface obtained by form-finding, and divide the space film surface into several space film strips;
(2) Open the space membrane strip as a flat membrane;
(3) Release the prestress and perform strain compensation on the flat diaphragm (that is, consider the elastic retraction of the membrane after the release of the prestress);
(4) According to the above results, plus the membrane structure at the joints and corners of the membrane, the plane cutting sheet and the membrane structure carport are obtained; the blanking drawing of the membrane material and the processing drawing of the membrane surface, the cable membrane are given. structure.
The cutting line refers to the connecting line between the film strip and the film strip on the curved surface of the space film, that is, the seam when the cutting piece is spliced with the cutting piece. The placement of cutting lines should follow these guidelines:
(1) Beautiful, with outstanding visual effect;
(2) The force bearing function is excellent, and the cutting line is generally placed in the same direction as the meridian of the membrane material, along the main stress direction of the membrane surface;
(3) It is easy to process and prevent the cutting lines from being too concentrated, so as to facilitate the disposal of corners;
(4) Saving, that is, saving the membrane material and making the total length of the seam as short as possible.
