Definitions
- the present invention relates to a pneumatic component in the form of an elongated airtight and pressurizable hollow body with at least one on the load side along the hollow body extending pressure rod and at least two tensioned in opposite sense helical tension around the hollow body tension bands.
- the drawstrings start or end at node elements, which are arranged at the ends of the at least one pressure rod, and wrap around the hollow body at least once.
- pneumatic components are known per se, for example from WO 01/73245.
- the pneumatic component consists of an example textile-based flexible flexible gas-tight hollow body.
- At least one form-stable pressure rod extending along a surface line is arranged on the outside such that it is supported by the hollow body and can not buckle.
- At the ends of this push rod two drawstrings are attached, which wrap around the substantially tubular hollow body in opposite sense of helix once and cross each other on a generatrix of the hollow body, which is opposite to that of the push rod, on half the length of the hollow body.
- the pneumatic component disclosed in WO 01/73245 has various disadvantages which are manifest in practical handling: the pressure rod, which alone is too long, has to be dismantled into individual parts for reasons of transport and assembly, which, for example, become dull on a construction site butt joined to one another and inserted into tabs intended for this purpose. Likewise, the creation and tensioning of the drawstrings can only be done on the construction site. Since the drawstrings and push rods must be laid in the appropriate node elements, which for recording are suitable for tensile, compressive and bearing forces, results in a considerable installation effort on the site.
- the object to be solved by the present invention is to provide a pneumatic component which can be erected on a construction site without significant assembly.
- FIG. 5 shows a fourth embodiment of a compression rod in cross section
- 7 is a node element with a push rod in side view
- 8 shows a fifth embodiment of a compression rod in cross section
- FIG. 11 shows an application example for the flexible pneumatic components according to the invention in an isometry
- FIG. 13a shows two pneumatic components with a connecting element in a side view in the flaccid state
- Fig. 13b two pneumatic components with a connecting element in a side view in the pressurized state.
- Fig. La, b are representations of the inventive flexible pneumatic component in cross section; Fig. La shows it in the flaccid, Fig. Lb in pressurized condition.
- the pneumatic component consists of a flexible casing 1, on which one side a pressure rod 2 in the form of a flexible plate made of a pressure-resistant material, for example, is glued over the entire surface.
- the shell 1 is made for example of a textile-reinforced plastic and glued gas-tight or welded.
- Another solution for the shell 1 consists of a tube of low-stretch textile material - for example, aramid fibers - in which a gas-tight manufactured hose made of elastic plastic - for example, polyurethane - is inserted.
- the push rod 2 In the deflated state, the push rod 2 is flat, which allows / roll the pneumatic component and transported in the rolled state, as shown in Fig. 2. If the empty and flaccid - and possibly rolled-up - pneumatic component is now acted upon by compressed air via a valve 3, it unrolls first and then takes in the unrolled, but still flaccid state slowly the cross-sectional shape shown in Fig. Lb. In this case, the pressure rod 2 is bent into the functional form of a cylinder segment shown.
- the stability of the flexurally elastic pressure rod in its functional form has two main reasons: On the one hand, the curved functional shape increases the area moment of inertia of the pressure rod, on the other hand, the pressure rod by the Caribbeanmenmenspiel with the drawstrings and the pressurized shell 1 is radial to its longitudinal axis on an air spring stored, so not hanging freely between its ends.
- the larger area moment of inertia and the sprung mounting of the push bar increase its own
- Push rod 2 with the shell 1 on the push rod 2 such that this is also stretched by ⁇ u .
- the area moment of inertia of the pressure rod is further increased and the buckling load is increased.
- FIGS. 3 to 6 Variants for constructing the pressure rod 2 and for increasing the buckling load are shown in FIGS. 3 to 6.
- the pressure rod 2 is arranged inside the flexible casing 1 and consists of a gas-tight hollow body 4.
- the hollow body 4 is for example made of two, flat adhered to each other at the edges or welded, plates 6 constructed with the aforementioned properties. If the hollow body 4 is now set with a pressure medium under a pressure pi, the interior of the flexible sheath to a pressure po ⁇ P ⁇ , the tube-shaped pressure rod generated by the hollow body 4 can without bending take the intended longitudinally acting pressure forces.
- FIG. 4 a further means for increasing the area moment of inertia of the pressure rod 2 is shown.
- the - initially - flat pressure rod 2 is mounted inside the flexible casing 1, welded or glued.
- an elastic joint 5 which extends centrally over the entire length of the push rod., A web 7 is articulated. In the pressureless state of the pneumatic component according to the invention, the web 7 is essentially parallel to the plate 6 of the pressure rod 2.
- a multiplicity of filaments 8 extend transversely through the flexible casing 1; in the unpressurized state of the flexible casing 1, the filaments 8 are loose, in the pressurized state of the flexible envelope 1, however, stretched so far that is brought by the pressurization of the flexible shell 1 of the web 7 from the original position in the illustrated in Fig. 4, in which he is essentially perpendicular to the plate of the push rod 6.
- 5 and 6 are two variants of a further arrangement, which serve to increase the area moment of inertia.
- several, for example, five, flexible and gas-tight tubular sheaths 9 are placed on the plate 6 of the push rod 2 and connected to it.
- flexible plates 6 are also inserted and connected to the shell 9.
- FIG. 5 is a representation of a first embodiment of a node element 11.
- FIG. 8 is an illustration of a pneumatic component with two pressure rods 2 arranged along opposite generatrices of the flexible sheath 1.
- FIG. 8 The characterizing features described with reference to FIGS. 1a, b remain the same - apart from the double design of the pressure rod 2.
- a pneumatic component constructed in this way has at least one pair of drawstrings 12 for each pressure rod 2, which loop around the pneumatic component at least once in opposite directions.
- the arrangement of the eyelets 13 may be adapted to the particular needs as long as the zero-sum condition for the force vectors is met.
- the eyelets 13 can also be arranged so that the longitudinal axis of an eyelet 13 intersects with the longitudinal axis of the pneumatic component or else comes to lie below this latter longitudinal axis.
- a pneumatic component with two pressure rods 2 according to the embodiment of FIG. 3, 4, 5 or 6 are executed, this can be done by attaching a pressure rod designed according to these exemplary embodiments twice, as shown by way of example in FIG. 9: here the push rod 2 with the hinged web 7 is performed twice. Instead of the mantle line opposite the push rod 2, the opposite web 7 serves as a fastener. tion location for the filaments 8, which raise the webs 7 under the action of the pressure medium.
- the properties of the pneumatic component which are described with reference to FIGS. La, b and 2, thereby obtained.
- An embodiment of a node element 14 for receiving two pressure bars 2 is shown in FIG.
- FIG. 11 shows an application example of the use of several inventive pneumatic components, for example according to FIG. 10, for the establishment of a pneumatic and essentially self-erecting element construction, here a framework for a roof.
- 18 pneumatic components are in principle connected to one another in a suitable manner, in principle of the same type. Connecting elements 15 according to FIG. 12, for example, which are subsequently described, serve for this purpose.
- a plurality of pneumatic components can be combined with their node elements 14 or in an actual node.
- three to four pneumatic components are connected in one connecting element 15.
- the upstanding in Fig. 11 on the ground ends of the pneumatic components may be equipped instead of a node element 15 with a shoe.
- the element construction of Fig. 11 may be coated with a suitable foil or tarpaulin either before or after erection.
- Fig. 12 shows an embodiment of the connecting element 15, here for four pneumatic components to be connected. These can, as shown in FIG. 12, be designed with two pressure rods 2. In the embodiment with a single push rod, the lower eyelets 13 can be omitted.
- Per attached pneumatic component are four eyelets 16th provided, two in coaxial arrangement, through which a bolt 17 is inserted.
- the connecting element 15 can be designed as a welded sheet metal construction or as a cast part.
- the angle between two flexible pneumatic components can be determined in their functional form.
- the outer contour of a built by flexible pneumatic components structure is set.
- a first connecting element for example that in the gable of the building of Fig. 11, two pneumatic components with the bolt • 17 are connected after the still slack pneumatic components have been rolled out are.
- Other fasteners and pneumatic components can be mounted in the same process.
- the pneumatic components are pressurized. This gives the printing rods their functional form.
- they are therefore able to absorb the built-up in the connecting elements moments and thus lift the whole structure from the ground and set it up.
