Description
Technical field
The utility model belongs to construction engineering technical field, and it is big to can be applied to gymnasium, Convention and Exhibition Hall etc. for more particularly to one kind
Across the rigid roofing cable dome structure with ring support of building.
Background technology
Cable dome structure is the tensioning knot that American engineer Geiger proposes according to Fuller tension integral structure thought
Structure.Reached within 40 years early in 20th century, the operation that Fuller is considered as universe is carried out according to the overall principle of tensioning, and thus he sets
Think that really efficiently structural system should be the self equilibrium systemses of pressure and pulling force.1984, his student --- sculptor
Snelson completes first tensioning block mold, and devise sculpture for city based on this, it was demonstrated that setting for Fuller
Think, be acknowledged as a starting point of modern tension integral structure development.Fuller is thus by bigger encouragement and inspiration, in 20
The beginning of the sixties in century is delivered the concept and preliminary theory of Tensegrity System.He describes in greater detail in the patent of 1962
His structure thought：It is reduced as far as pressured state in the structure and structure is in continuous tensile state, so as to
The imagination of his " depression bar isolated island is present in the ocean of pull bar " is realized, and proposes this concept of Tensegrity for the first time.
Since tensioning global concept proposes, scholars（Emmerich, Vilany, Pugh, Motro, Hanaor etc.）To various
The tension integral structure of structure type is studied, but this structure is mainly used in artistic sculpture and model since some time
Experiment, build and occur without feature.
Famous American engineer Geiger in 1986 first according to Fuller tension integral structure thought, utility model
A kind of rope bar prestressed dome i.e. cable dome structure being supported on inplane pressure ring beam, and Successful utilization is in the Soul Olympic Games
Gymnasium and fencing hall.Subsequent Cable dome has obtained further development, and is applied to multinomial heavy construction in succession, as the U.S. is tall
Control sub- dome, Japanese day city dome, Argentinian La Plata stadium etc..
Although cable dome structure has obtained quick development abroad, the development in China relatively lags behind, on the one hand
It is due to the reason for its technical difficulty is larger, is on the other hand due to the roofing covering material of Cable dome frequently with membrane material, membrane material
Though have the advantages that permeability is good, it is more sensitive to wind load which limit the form of building, to environmental requirement height, it is impossible to
Meaning hangs other loads, and cost is higher, reduces the scope of application of Cable dome.If it can be covered on Cable dome using rigid roofing
Cover material, its scope of application is will be enlarged by, and substantially reduce the cost of cable dome structure, be advantageous to its popularization.
