Description
Technical field
The present invention relates to a kind of Single Layer Sphere Grids frame intermediate cam shape unit film devices, which is by triangle sets
The Single Layer Sphere Grids frame membrane structure of part unit composition, this film device are that one kind can eliminate PTFE film fold, even tension
Open film device.
Background technique
In the membrane structure of space, it is by various triangular that Single Layer Sphere Grids Shell, which has the characteristics that structure is simple, reasonable stress,
Frame forms after connect fastening with ring flange by bolt after overlay film, in spherical reticulated shells actually use, the fixation of diaphragm
Be realized by the side rod of its two sides triangular framing by bolt, and for convenience spherical reticulated shells installation, in a pre-installation
Membrane material is linked together with triangular framing by bonding mode, external membrane material is usually to be tensioned to single layer triangle
The outside of shape frame, the connection of membrane material and triangular framing is generally taken by hand in traditional Single Layer Sphere Grids frame membrane structure
Tight mode causes membrane material to have the following problems when being tensioned on triangular framing:
(1) when single triangular element carries out manual tensioning film, manual pulling force unevenly be will cause in entire triangle
In plane, the tension of each point is also uneven, and membrane material is made elastic different phenomenon occur, that is, the point having is very tight, and some points are loose, leads
Cause film surface fold；
(2) installation of membrane material is installed according to manual, and the size of tension varies with each individual, each triangle membrane element structure
It is big to will appear the triangular element tension having when being mounted to diameter of Spherical Volume structure, some triangular element tension is small, or even goes out
Existing slack and undisciplined phenomenon；
(3) due on each triangular element Tensity size unevenly will result in when being mounted to entire space structure, due to
Tension is redistributed, and buckling phenomenon occurs in the connecting rod occurred in the triangular framing of support membrane material, this can be severely impacted
To the stability problem of entire space structure part.
Based on the above reasons, an a kind of triangular element that the present invention designs film device, not only can solve problem above, protect
The constant of tension is demonstrate,proved, also can guarantee that integral membrane material tension is uniform, smooth when being mounted to entire space structure, and can improve and open
The efficiency of film.
Summary of the invention
The purpose of the invention is to overcome a film out-of-flatness, each side rod tension in existing in the prior art membrane process
