Description
Technical field
The present invention relates to a kind of inflating and stretching integral film, can directly apply to the large span architecture roof system, as meeting, multi function hall, sports palace etc.Belong to the building structure technology field.
Background technology
Membrane structure starts from nineteen fifty-two, and its canonical form is skeleton film, stretch-draw film, air bearing film, balloon membranes, stretching integral film.Wherein, skeleton film is by complex topology spatial mesh structure support membrane, the stretch-draw film is by the mast that disperses, arch supporting and by cable stretching and stabilising membrane, the air bearing film produces pressure reduction with supporting building film inside and outside making architectural space by inflation, balloon membranes adopts inflation to make the inside and outside pressure reduction that produces of air chamber be used for building structure to keep air bag rigidity, stretching integral film is interrupted depression bar by continuous tension cord and forms the equalization of strain system, these membrane structures all are widely studied, wherein skeleton film, stretch-draw membrane technology maturation, extensive use both at home and abroad, but, the air bearing film, balloon membranes, stretching integral film is but because characteristics separately, technical difficulty is used less, and stretching integral film is not used as yet in China engineering field.
(China Construction Industry Press has elaborated the characteristics of air bearing film and balloon membranes in 2005.3.) in " the membrane structure engineering design " of Chen Wujun work.Wherein, air bearing membrane building activity space has certain affected by high, wind resistance and anti-snow poor stability; It is less that balloon membranes is crossed over power, is used for small building, grid cell building more.Zhang Li-mei, " Manufacture error and its effects on the initialpre-stress of the Geiger cable dome " (International Journal of Space Structures of Chen Wu-jun work, 2006,21 (3): the Geiger rope dome and the Zhang Li-mei that adopt 141-147.), " The initial pre-stress found procedure and structural performance researches forLevy cable dome based on the linear adjustment theory " (Journal of ZhejiangUniversity SCIENCE A of Chen Wu-jun work, 2007,8 (9): the Levy type rope dome that adopts 1366-1372.), all are stretching integral films, these stretching integral films are because the tension force importing, the technical difficulty of control is big, shortcomings such as the rigidity of structure is less, engineering is used few.
Summary of the invention
The objective of the invention is to deficiency, a kind of inflating and stretching integral film is provided, have that span is big, bearing capacity is high, a lightweight, characteristics easy for installation, in can be used for, long-span roof, adapt to multiple plane, facade architectural space layout at existing membrane structure.
For realizing such purpose, the ridge paddy shape negative gauss curved surface tension film that inflating and stretching integral film of the present invention is covered by its top by a plurality of aerated film integral tension beams is connected to each other and forms, and can form bigger span.Aerated film integral tension beam is the ridge of inflating and stretching integral film, is formed by connecting by air bearing elastic plate, spindle aerated film, spiral stretching rope, gives the inflation of spindle aerated film, guarantees the rigidity and the supporting capacity of aerated film integral tension beam.Ridge paddy shape negative gauss curved surface tension film be inflating and stretching integral film go along with sb. to guard him main body, also be its important stressed element; In the middle of ridge paddy shape negative gauss curved surface tension film, press valley cable, as the steadying line of inflating and stretching integral film.
Concrete structure of the present invention is: connect into an aerated film integral tension beam by air bearing elastic plate, spindle aerated film, spiral stretching rope, the air bearing elastic plate around being fixed on the spindle aerated film, fills the superpressure air by the spiral stretching rope in the spindle aerated film.A plurality of aerated film integral tension beams adopt the mode of parallel, fan-shaped or circular arrangement, and the ridge paddy shape negative gauss curved surface tension film that covers by its top is connected to each other formation inflating and stretching integral film structure.The centre of ridge paddy shape negative gauss curved surface tension film presses valley cable, and both sides are provided with the film fixed edge.Each fixes air bearing elastic plate two ends one and is hinged contact.
Among the present invention, aerated film integral tension beam comprises air bearing elastic plate, spindle aerated film, spiral stretching rope, and inflation makes aerated film integral tension beam be shaped, keep rigidity, bearing load to the spindle aerated film with blast fan.The spiral stretching rope connects the air bearing elastic plate on aerated film top and spirality and walks around below the aerated film then that spiral can be wound up as the continuous helical line around connecting to the air bearing elastic plate according to span.
Ridge paddy shape negative gauss curved surface tension film is connected with pressing plate by bolt with the air bearing elastic plate; Valley cable is pressed in the centre position of ridge paddy shape negative gauss curved surface tension film, applies certain pulling force and is anchored in the bottom building in two ends afterwards, plays the Stability Analysis of Structures effect; Ridge paddy shape negative gauss curved surface tension film limit connects building fixed edge or free edge.Rope aerated film integral tension beam is connected anchoring by the contact that is hinged at two ends with the building bearing post.
The present invention is the innovation to balloon membranes, air bearing film, stretch-draw film, stretching integral, girder structure, make full use of rope tensile strength height, air bearing elastic plate pressurized, aerated film air pressurized to the continuous supporting of elastic plate, the characteristics of the free stretch-draw forming of film, the span ability increase, lightweight, the installation shaping that realize the inflating and stretching integral film structure are simple and direct, can be widely used in and stride public building roof system, industrial construction roof system, emergent earthquake relief work place etc. greatly.
