The specific embodiment
Fig. 1 a, b illustrate first embodiment of pneumatic plate-like piece 1.Fig. 1 a and Fig. 1 b illustrate pneumatic plate-like piece 1 with vertical section BB and cross section AA respectively.The power transmission on its end of two pressure/tensile elements 2 interconnects with connecting and around hollow body 3, hollow body is made also and can be exerted pressure by fexible film 9.Film 9 is because the tensile stress of effect on it is less for example can be made by partially fluorinated thermoplastic (for example ETFE, Ethylen-Tetrafluor-Ethylen) highly transparent and extremely thin film.
Pressure/tensile elements 2 both had been applicable to that absorbing pulling force also was applicable to absorption pressure and for example is made up of steel or timber.Two pressure/tensile elements 2 are with for example spacing of rule
aInterconnect by means of tensile elements 4 power transmissions that only absorb pulling force with connecting.These tensile elements 4 pass hollow body 3.They for example pass the airtight passage 5 that connects hollow body 3.Hollow body 3 is not connected with pressure/tensile elements 2.Pneumatic plate-like piece 1 is supported on the column 17 in the zone that 2 power transmissions of pressure/tensile elements connect basically.
If hollow body 3 is applied in pressure, pressure/tensile elements 2 is pressed off and pre-tensioned tensile elements 4 so.If plate-like piece 1 is lateral stressed, pressure acts on pressure/tensile elements 2 of being in above the hollow body 3 and tension in the pressure/tensile elements 2 that passes below hollow body 3 so.Pressure/the tensile elements 2 that bears pressure is tending towards buckling under load.Connecting portion 6 between pressure/tensile elements 2 and the pre-tensioned tensile elements 4 is looked as middle standing pillar 18 uses of pressure/tensile elements 2 and from pressure/tensile elements 2 static angles of bearing pressure and is formed a press rods or a pressure disc, and described press rods or pressure disc have along with the pre-tensioning of tensile elements 4 with along with horizontal service load power
FThe fixing or flexible middle standing pillar 18 of degree.Fig. 2 illustrates basically the quiescent conditions of equivalence for explanation by crossbeam, this crossbeam in intermediate supports between two columns 17 on a plurality of fixing middle standing pillars 18.
Former for what simplify below because pneumatic plate-like piece 1 hypothesis is for example passed through gravitation
FThe one-sided stressing conditions that causes.Therefore pressure/the tensile elements 2 that bears pressure above generally speaking is called pressure piece 7, and the pressure/tensile elements 2 that bears pulling force generally speaking is called tensile elements 8.Under the situation that this one-sided stressing conditions will not reverse, the pressure/tensile elements 2 that bears pulling force all the time is self-evident also as simple tension spare 8 formations, and this tensile elements only bears and can bear pulling force.For example can use wire rope or wirerope for this reason.But under the situation on roof, the weight by the wind-force roof structure can obtain overcompensation and therefore also cause bearing pressure on bottom pressure/tensile elements 2.Pressure/tensile elements 2 alternately bears pressure or pulling force also occurs under the plate-like piece situation of vertical orientation when for example using as wall.
As long as the pre-tensioning of vertical tension spare 4 is greater than the firm power that prevents that pressure piece 7 bucklings are required, connecting portion 6 just plays the effect of the fixedly middle standing pillar of supposition.Only surpass under the pre-tensioning situation of pre-tensioned tensile elements 4 in required firm power, skew just can appear in connecting portion 6.Superpressure in the hollow body 3
p, the spacing between the pre-tensioned tensile elements 4
aAnd the width of pressure piece 7 and height selection like this under the situation of plate-like piece 1 given load, make pre-tensioning all the time obviously greater than the firm power that prevents that buckling is required.In this regard, be suitable for spacing
aMore little, the pre-tensioning of pre-tensioned tensile elements 4 firm pressure pieces 7 is also just more little.Spacing
aBig more, though this firm pre-tensioning is also just big more, also strengthened simultaneously on the pressure piece 7 built on the sand, unsupported length, thereby even also can cause its buckling producing under the less axial compression situation on the pressure piece 7.Firm and the best distribution and the quantity in weight aspect of pre-tensioned tensile elements 4 can according to circumstances can numerically be optimized.
