Space framework

The invention relates to a space framework with connecting elements having node elements, which are detachable from each other ν ε rbi p. db 3 rs p. Bodies bestshsp. up. d dsrsn U nn ü! s π t β L ü π ⁿ snn ähsr η d is spherical or polyhedron-shaped, and in particular with tubular and / or rod-shaped connecting pieces that can be detachably connected to the connecting elements of the spaced-apart knot elements, for example by means of screw connections.

Space trusses of this type are, for example, in DE-OS 29 17 422 described and illustrated. The junction elements of the space framework consist of hollow, two-part metal spheres with radial through openings. These metal balls show spacious access openings covered by caps are on. The caps are held on the balls by hold-down springs. Both the manufacture as afch the Assembling such node elements is complex and expensive, because, on the one hand, many procedural steps are required, to get from the blank to the finished ball.

Furthermore, there is a not inconsiderable disadvantage of the known node element the fact that the area of the metal balls having the cap is not suitable for connecting Connections can be used that the distribution of forces on the node element is non-uniform. It is Although possible, the influence of the unfavorable distribution of forces to reduce, for example, the wall thickness of the Hollow spheres are chosen thicker. However, this leads to a further increase in the cost of materials due to the increased cost of materials Node elements.

$ Further advantageous measures of the invention can be found in the

Subclaims.

₍ s A particularly useful embodiment of the invention can be achieved in that the node elements each consist of three bodies arranged at right angles to one another, whereby these node elements consist of an inner body, which is arranged in a central body, and an outer body in which the In this case, which is of the greatest importance for the practical application of the invention, a node element that meets all the requirements of a space framework can be assembled easily and quickly in the most elementary way

Connectors at the juncture with the body.

In order to ensure the form and force fit of the node elements in all cases of use, it is provided that the; ■ 'inner body with the middle and with the outer body «■' on the outside, while the middle body with the inner ( body on the inside and with the outer body is externally connected.

A particularly advantageous measure of the invention provides that the outer and inner contour of the body is a polygon, preferably an octagon, the outer body being a regular octagon, the diagonally opposite sides of which are arranged at a distance of χ (cm) from each other wherein further the central body, except for two diagonally opposite sides whose outer width across flats is χ (cm), having substantially the same shape as the outer body and the inner body, except for two diagonally opposite sides, the outer Sch Lüsse I white x (cm), has essentially the same shape as the middle body, these two sides being perpendicular to the sides of the middle body, the outer wrench size of which is χ (cm). In this case, the result is _: a node element which nevertheless offers connection options for connecting pieces that are evenly distributed in all three planes perpendicular to one another.

of the knot ene element is particularly good, since the forces compensate each other. The node element can also then not be deformed when the body is out proportionately thin-walled rings exist.

In the case of node elements whose bodies are made up of, for example, circular Rings exist, the desired form and force fit can be achieved by the Connecting parts of the interconnected C body have recesses of complementary shape. if souche bodies are made of elastic material, as in a further expedient measure of the invention provided is, then the assembly of individual node elements can be carried out particularly easily and quickly.

In the case of junction elements of this type, it is advantageous to design the connecting elements as tabs or eyes, whereby these measures can also be taken so that the tabs or eyes have circular bores, the central axes of which are at right angles to the connecting plane in which the tabs or eyes are located, get lost. Work in this embodiment of the invention, the r of the connecting pieces s forces arising tangential to the node elements evenly. But if the connecting pieces are angled at right angles at their ends, then the forces act radially again, so f

that these compensate each other.

The tabs or eyes can either be on the inside and between the connecting parts of the body or be attached to the outsides of the body.

The advantages achieved by the invention consist in particular in a substantial simplification of the Manufacture of the node and bar elements, as well as in one

noticeable simplification of the honing technique. if for example a node element with eighteen Connection elements (rod connection options) made should be, then only three are trained differently Rings with eight holes each required. The Rings can easily be used as sections of an extruded profile (aluminum), an extruded profile (Steel) or a cold or hot deformed hollow profile getting produced.

After punching out or drilling out eight openings in each body (ring) and after a possible one Surface treatment are the individual parts of the node element montai'ef ert i g.

The connection technology according to the invention results in a simplification of the structural design of the connecting pieces (rod elements). Here, namely, the rod elements can be designed so that they each have only one threaded hole on the end face. In the event that the connecting elements (rod connection surfaces) are in one ! _{If the} extrusion process (aluminum) is already stamped into the body (rings), the connecting pieces (rod ends) must be designed in such a way that they have complementary connection surfaces. The individual junction element gains its final shape and structural reinforcement only when it is screwed to the connecting pieces. This is a fundamental simplification in the manufacture of spatial gates.

Particularly noteworthy here is the possibility of quick assembly with electrical screws, the degree of pre-assembly on the floor and also the assembly direction freely

Part of a space framework is shown in the drawing Connection elements having node elements shown, which consist of detachably connectable bodies and whose sheathing is approximately spherical or polyhedron-shaped is. The space framework also has tubular and / or rod-shaped connectors that with the Connecting elements of the spaced apart Node ELEMENTS, for example, by means of screw connections Are releasably connectable. The node elements are off annular and concentrically arranged bodies formed. Each body defines a connection level with the same Number of connecting elements.

As can be seen in particular from FIG. 1, the junction element 1 consists of three arranged at right angles to one another Bodies 2, 3 and 4, namely from an inner body, the Ir? a central body 3 is arranged, and an outer body 2 in which the central body 3 is arranged. the three named bodies 2, 3 and 4 each have an equal number of connecting elements 5, 6 and 7. in the In the present case, each body 2, 3 and 4 each has eight radially oriented, designed in the form of bores Fasteners on.

The bodies 2, 3 and 4 of the node element 1 are with one another so connected that the inner body 4 is connected to the middle body 3 and to the outer body 2 on the outside, while the middle body 4 with the inner body 4 on the inside and with the outer body 2 on the outside in Connection. This results in both a force-fitting and a form-fitting connection between the bodies 2, 3 and 4.

At those points on the body 2, 3 and 4 where each two bodies overlap, are the connecting elements (Bores) 5 and 6 designed so that they are with the adjacent Bohruηyeη the other body flue h th * It is therefore possible, the connecting pieces 10, 11 (see. Fig. 4) with the node element 1, for example, by means of different lengths (. 'To connect screws 12 and 13. The heads of screws 12 and 13 are located in the interior of the node elements 1.

The bodies 2, 3 and 4 are designed so that their outer and the inner outline is a polygon or circular »

In the embodiment of FIGS. 1 to 7 have the Body 2, 3 and 4 an octagonal outer and inner outline. Here the outer body 2 is a regular octagon, its diagonally opposite sides 15 and 16 with a clear distance of χ (cm) from each other (Fig. 5).

3 and 4 show that the node element, e 1 with connecting pieces 10 and 11 or 10 "and 11 'can be connected, the diameters of which differ significantly Large diameter connectors 10 'and 11' are tapering towards the node elements 1 Connection supports 26, 27 are present, with which one Independence between the node elements 1 and the Connection pieces 10 ', 11' with regard to their diameter is attainable. This is particularly important if the user wants a space framework in which the Node elements should not appear. On the other hand, a three-dimensional framework can also be produced in which the node elements are significantly larger compared to the diameter of the connecting pieces and, for example, than Serve lamp housing.

8 to 11 is a node element 30 with the for this purpose required annular bodies 31,32,33 shown. Of the inner body 31 has recesses 35 and 36 on the outer circumference, the shape of which is complementary to the recesses 37 and 38 of the middle and outer body 32 and 33 are connectable. •>. Because this body is made of an elastic material can form a form and force fit through deformation Connection between the individual bodies can be easily established.

On the inner circumference of the bodies 31, 32 and 33 are eyes 40, 41 and 42 formed as connecting elements of the node elements 30 serve.

In the case of the node element 50, as shown in FIG. 12, the eyes 51 and 52 are formed on the outer circumference of the bodies 55, 56 and 57. In this case too, the bodies 55,

The three bodies (rings) of the node elements, which are at right angles to one another, also form through the screw connection the bars a spatial structure, which in relation to the Transmission of tensile and compressive forces similar to a hollow sphere

is.

The width, the thickness and the diameter of the bodies

are inevitably related, but are fundamentally variable.

That means: the definition of one of these three variables determines the dimensions of the other two bodies (rings).

The ring-shaped bodies can also be designed with a much larger diameter. It then eats itself radially directed through inlet openings accessible bearing shells as Insert connecting elements. Wear the connectors then cylindrical bearing bodies that are attached to the Inlet opening matched connecting web are connected to the connecting piece. The connectors can then inserted transversely to the annular body in the bearing shells and by spreading the bearing body therein be determined.
