- 11 is a tensile structure with nine tension-pressure elements in a triangular shape, _ _
- FIG. 14 is an isometric view of a variant of FIG. 13,
- FIG. 15 is an isometric view of a second variant of FIG. 13.
- Fig. 1 is a schematic representation of a first embodiment of the inventive concept.
- a tension-compression element 1 is composed of a plurality of tension-pressure bars 2, which are hinged together in joints 3, and several tension elements 4.
- the axes of the joints 3 extend in the illustration according to FIG. 1 perpendicular to the plane of the drawing.
- the drawstrings 4 are preferably designed as wire ropes and bend without bending.
- drawstrings 4 made of textiles or plastics, metals, and combinations of such materials, such as aramid fibers or similar materials. Instead of in the joints 3, the drawstrings 4 may also be attached adjacent thereto.
- each two may be present, which cross over each other when the attachment to the upper and lower flange next to the joints takes place.
- One possibility is also in the attachment of the two bands on the joint on the upper chord resp. Bottom and at the adjacent train-pressure rods of the corresponding joint of the lower flange resp. Upper belt.
- the elements labeled 2, 3, 4 form a flat truss and are designed as such for loads F acting vertically from above.
- Fig. 1 is a non-illustrated also included in the inventive concept, in which the
- Train-pressure bars 2 are designed differently long, with the restriction that for each in Fig. 1 above lying (ie located in the upper flange 11), a lying in Fig. 1 below (ie located in the lower flange 12) at the same time homologous point is installed.
- a tension-pressure element according to FIG. 1 is placed in this embodiment in the plane of symmetry of an air body 5, as it is shown as a cross section in Fig. 2.
- This air body 5 consists of a tensile sheath 6, in which, for example, two tube-like hollow bodies 7 made of elastic and gas-tight material are inserted.
- Other solutions are also according to the invention, but require some effort to seal the air body 5 against the tension-pressure element 1 and the drawstrings 4.
- the two hollow body 7 may be connected or basically represent only a single hollow body, which suitable bushings for having mechanical parts.
- the shell 6 and the hollow body may be a single element, if suitable seals are installed.
- the sheath 6 may also be connected by means of pockets with the tension-push rods 2, as shown in the lower part of Fig. 2. Due to the line tension, which act in the sheaths 6, top chord 11 and bottom chord of the tension-compression element are laterally stabilized, since the sheaths there begin with their line tensions with generally symmetrical tensile forces to the left and to the right. The vector sums of these line voltages act upwards and downwards (with respect to FIG. 2) and generate in the drawstrings 4 tensile forces which bias them. These drawstrings 4 are therefore capable of receiving outwardly acting compressive forces F (see Fig. 1) until the said biasing forces acting on them
- the compressed gas takes on three tasks:
- FIG. 3 shows such a support structure according to the invention in isometry, omitting the elastic hollow bodies 7.
- the tensile-compression bars 2 located at the ends are each detachable in a respective node 9 , put together.
- Fig. 4 shows only consisting of train-pressure bars 2 and tension bands 4 train-pressure element in a relaxed and unloaded state, partially folded. In the relaxed state, the drawstrings 4 are limp.
- the illustration of Fig. 4 refers to the same tension-compression element as that of Figs. 1 and 3.
- the tension-compression element can be collapsed without having to disengage the connections to the node 9 , 5 is the schematic representation of a second embodiment of a foldable tension-compression element. While the structure of the air body 5 (not shown here) is substantially the same, the differences of the various embodiments are primarily in the design of the train-pressure element.
- the tension-compression member consists of three pairs of tension-compression rods 2, all of the same length i, with the length of the tension bands increasing towards the center. Adjacent to the knots 9 is in the so-called upper chord 11 - in Fig. 5, the above-illustrated tension-pressure bars 2 - above each a train-pressure rod 2 of length l_ with a train-pressure rod 2 of length b in If this condition is met, the tension-compression element can be folded without releasing the connections in the node 9. As in the previous, second embodiment, the joints are third in turn connected by drawstrings 4.
- FIG. 6 shows a third exemplary embodiment of a train-pressure element according to the invention.
- the drawstrings 4 each extend from the center of each train-pressure rod -6-
- the drawstrings 4 in each case extend, as in the previous exemplary embodiment, from the middle of each tension-compression rod 2 to the opposite joint 3. All tension-compression rods 2 are of equal length 1_ with the exception of in Fig. 7 above, to the node 9 subsequent. These each have a length b ⁇ l.
- two tension bands are again provided with a condition: h *> £ / 2.
- FIGS. 8 to 11 show support structures according to the invention, which expand in two dimensions and thus in principle represent surface structures.
- Fig. 8 shows a first surface structure, which is constructed of four arranged in a rectangle 13 supporting structures.
- the support structures used in this case can consist of one of the exemplary embodiments already shown. They are connected to each other in the nodes 9 and form there a real or virtual joint 10.
- the said rectangle 13 is covered by a suitable membrane 14 and thus forms, for example, a roof or a canvas. Any discharges for rainwater are not shown, but can be provided at appropriate locations.
- a triangle 15 is formed from three-not necessarily identical-linear support structures, again according to one of the previously described exemplary embodiments. Again, a strained membrane 14 covers the support structure.
- the tensile stresses occurring in the exemplary embodiments according to FIGS. 8, 9 and thus tilting moments and lateral bending moments in the tension-compression elements 1 can be at least partially compensated by the fixings in the joints 10 and by a wider configuration of the tension-pressure rods 2.
- each tension-pressure element is half of a shell 6 with an elastic hollow body 5 (not shown). appropriate.
- four air chambers 16 are arranged, which are either gas-tightly connected to the train-pressure elements 1, or in turn are provided with elastic and gas-tight hollow bodies. Since the radii of curvature of the sheaths 6 and of the air chambers 16 are greatly different and the line tension in their sheaths is proportional to the pressure and to the radius of curvature,
- FIG. 11 An analogous embodiment to that of FIG. 10 is shown in FIG. 11. It is based on a triangular basic _
- An outer frame constructed on three tension-compression elements 1, each with a half shell 6, for example, in turn, each with an elastic hollow body 5 (not visible), carries a planar arrangement of crossing each other train. Pressure elements 1 according to one of the preceding corresponding embodiments. In each case, the nodes 9 are located on this outer frame. In the present representation 16 triangular chambers are thus formed, which in turn are designed as air chambers 16. The interfaces to the half-shells 6 may in turn contain webs 17 in order to prevent passage of the hollow body 7 between the drawstrings 4.
- FIG. 12 in addition to those of FIGS. 1, 5, 6 and 7, further tension-compression bars 2 are inserted. These run each of a joint 3 in the upper flange 11 to the right and / or left adjacent joint 3 in the lower flange 12. These do not hinder the folding process, but can increase the stiffness of the train-pressure element depending on the load case by absorbing compressive forces.
- 13 to 15 are views of another surface support, here in the form of a screen 22.
- Fig. 13a a stand 21 is shown, on which a number of foldable tension-pressure elements, for example according to Fig. 1, at least in a node, the inner node 9, is hinged.
- FIG. 13a can rest on the upright 21 or can be fixed with limited mobility.
- Fig. 13b shows the train printing elements 1 - without the air body 5 - in unfolded and stretched state.
- FIG. 13c shows the screen 22 in plan view.
- a first embodiment according to FIG. 13 d shows how each tension-compression element 1 is surrounded by two air bodies 5, as shown in FIGS. 2 and 3.
- a membrane 14 is drawn in between the individual tension-compression elements 1, which is stretched by the filling of the air bodies, together with the deployment of the tension-pressure elements 1.
- Fig. 14 shows a second embodiment.
- the field between two adjacent train printing elements 1 is respectively _ _
- FIG. 15 shows a third variant of the screen 22.
- 5 webs 23 retracted into the air body, which ever connect the bottom and the top of the shell 6 with each other. Between the webs 23, for example, in turn - at most elastic - hollow body 7 is inserted.
- This third variant compared to the second according to FIG. 14, has the advantage of being much thinner.
- the compressed gas with which the hollow body 5 are filled, can be compressed air or another gas.
- the gas can be heavier than air - for example, CO 2 - or lighter than air, such as so-called balloon gas or hydrogen.
