Can you imagine
A few simple ropes and steel can support the weight of an adult
Don't doubt that this is not magic
Such a structure is called a tensile whole
Invented by the famous American architect Fuller
The tensioning integral structure is a set of discontinuous compressive members and a set of continuous tensile elements
Composed of self-supporting, self-stressing spatial structures
Fuller proposed a concept in a 1948 lecture
Gravity is invisibly like a big net
He will be the various celestial bodies in the universe
It is like a stressed island floating in the middle of a gravitational pulling ocean
In the course of the speech
A student named Snelson was inspired
A work of art called "Snelson'X" was designed
After reading it, Fuller suddenly realized
Isn't that exactly the answer you're looking for?
So Fuller used the new term "tension" and "whole" to synthesize
"Tension whole" is named after it
However, the design of the tensioning integral structure dates back to 1921
At the Exhibition of Architectural Models in Moscow
Sculptor Johnson showed off a model
It is composed of three rods and eight ropes
And the eighth cord has a non-stressed effect
It controls the whole
People call it three-bar eight-string
This model does not have stiffness
The contraction of any one cable will produce an institutional displacement of the model
But this is very close to the later three-shot nine-rope
The three-bar nine-rope looks a lot like a triangular prism twisted at an angle
The endpoints of each member are connected by three cables
These cables provide axial pressure to the compression bar
And the member endpoints are fixed
Use such widgets
Snelson designed a minaret thirty meters high
The work is now on display in a park in Washington, D.C., USA
This minaret looks very simple in appearance
A clever combination of steel rods and ropes
But it feels very impactful
Most of the buildings that use the tension and tension of the whole structure are a combination of ornamental and practical
Take, for example, a solar pedestrian bridge in Australia
The pedestrian bridge looks like knitting from a distance
That's because it references most of the components on the tensile mechanics implementation bridge
And the bridge is also equipped with an advanced light-emitting diode lighting system
That is what we often call LED lighting systems
This allows a variety of different light effects to be reflected on the bridge
Except for the building
ZhangLa as a whole has also infiltrated the field of robotics
The Tension Integral Robot was originally designed and developed by NASA
This robot is also a combination of steel rod and rope
Change the shape and size of the robot by dynamically extending and retracting the cable
Such robots are more flexible than traditional robots
They can crawl and roll
It looks more like an irregular sphere
In the future
NASA is highly likely to use such robots to explore the planet's surface
After all, many planets have rugged surfaces
Difficulty walking
Such a robot can effectively carry out detection work
Except for NASA
Researchers at the University of California, San Diego
The robot was also created using the structure of the tension and the whole
But the robot they developed is designed to clean the dust and garbage inside the pipes
The robot's batteries, motors, sensors, etc. are hidden in closed carbon fiber tubes
This is to effectively prevent them from being some inside the pipeline
May be corrosive liquid or gas damage
Ensure the safety of robots
Extended service life
The magic of this robot is also that
As long as there is a pipe wall that can borrow power
It can go to heaven and earth
The concept of the overall structure of the tension has been proposed for many years now
Gradually people integrated it into their lives
It can also be seen in the manufacture of furniture
And it's highly sought after
After all, such a novel design is placed at home
It will add a lot to the overall color
