Description

Node location for scaffolding or dergleicheng particular for the association of tubes in any desired arrangement, En are devices for Veränigung of rohrto-shaped or other generally metallic parts which bekanntg to one and the same node point said point converge. The frameworks and other metal structures have a large number of such nodes. However, the known devices have disadvantages, such as the relatively large number of different parts that make up them, which increases the cost price and makes it more difficult to procure the assembly and storage because of the restriction of the connection possibilities with regard to the number of pipes or parts to be combined and also the fastening angles in relation to the central part of the nodes so that the directions for attaching the pipes or the like. are given # openings for the mutual engagement of parts, which reduce their resistance, etc. * The node forming the subject of the invention avoids all these disadvantages. It is characterized by the fact that it has an axial rod that has one or more circular grooves with a slot or one in the passageway for introducing the puss at least one fastening member, whose cross-section corresponds to the cross-section of the circular grooves, so that the fastening part or the actuation parts are fixed at the same time be connected to the rod and they can be given any angular position with respect to the rod, these fastening members designed so that they can receive pairs of identical shells at their end or free portion at any convenient point, which are so shaped and their Legs are brought into engagement with one another by a mutual displacement after they have grasped a protruding head which is formed at the end of an end piece firmly connected to the pipe or other part to be connected, the contact surfaces of the legs of the joint The coupled shells are shaped in an identical and mutually corresponding manner so that their mutual position is determined without sliding and then their position in relation to the bearing part on the fastening members is also determined when the axial locking is carried out by means of a wedge which is connected to the Shells cooperates and is introduced behind the projecting head pressed against the fastening member * The invention is explained below with reference to the drawing by way of example.

Figure 12 is a section taken along line 12-12 of Pig. 11.

Pig. 13 and 14 show embodiments in which the ends of the tubes or elements directly form the pipes or parts for connection to the shells.

The central part of the node is an social rod 19 which is preferably cylindrical as shown. However, angular or other porms corresponding to the above characteristics are not excluded.

The rod 1 'has circular grooves la on the circumference, of which at the Example shown there are three, and which are equal or unequal widths can have the grooves la. However, a special cross-section which how shown is dovetail-shaped or another porm with extensions or the like. has # which make the connection with the connecting parts in the below as explained above.

In the longitudinal direction, the rod 1 has a pin or passage lb on the circumference on which ends of the rod and opens into the grooves la.

Furthermore, it is expedient, but not necessarily, at the ends of the rod 1 to provide abutment surfaces la which have openings or passages ld which allow the attachment of shells around a tube or element at each end of the rod in the axial extension of the rod or practically in a plunge to fasten with this. A mounting member 2 is particularly shown -in Fig. 2 and 3. This slide has a relatively small thickness and an elongated flat shape with a circumferential profile in the form of a circular ring 2a, the center of which lies on the axis of the same after assembly with the rod 1. The peripheral portion 2a of the part 2 is interrupted at the ends at 2b to enable the connection described below.

The section 2a is, for example, connected by radial ribs 2o and circular ribs 2d in a simultaneously rigid, strong and light manner with feet 2e , the number of which corresponds to the number of grooves la of the rod 1. The tubes 2e have a supplementary profile, which corresponds to the free insertion and the free displacement in the Mngsachlitz lb and in the circular grooves 1 a corresponds.

A plurality of fastening members 2 can thus be attached around the rod 1 at will and as required in the required radial positions and angular positions.

The junction includes as many pairs of shells as there are pipes or elements to be combined. There is only a single type of shell for the union and two identical shells are used to connect each end of the pipe or element to the fastener (see Fig. 19, 109, 119, 12).

This shell has the shape of a hollow cylinder section, which is extended on one side in a plane perpendicular to its axis by tabs 3.A, between which a passage 311 remains. Perner, the shell 3 by lugs 3.2 verlangerty between which a slot 31 bestehto the tabs 32 pass into a section 3e ausq welcher.in a vertical, is bent to the plane of the tabs 31 parallel plane.

The tabs % and 3e have depressions and projections 3f, which complement each other and, for example, have the shape of corrugations with a V-shaped cross-section, the mutual engagement of which holds the tabs of two shells inserted into one another with the required mutual displacement in a fixed axial position.

It should be noted, the inner surface 2 of DAAs portions 2a of the parts in recesses 2f and Vorspränge aufweistg which the recesses and protrusions 3f of the shells correspond with the same length and the position of these shells, and the pipes to be joined or elements la 'of the sections 2 .q. The contact surfaces of the openings 1d of the rod 1 can be formed in a corresponding manner.

Each pipe T or, if necessary. each other converging at the node point part 4 is provided at the ends with an end-st "ok, - which, by flanging of the tubes in a, A a plant times 4, h for example of the end pieces groove or a plurality of grooves 4 is fixed a. A collar 4.2 forms a stop for the pipe. This is followed by a contact surface 4 # d with a smaller diameter, which is followed by a head 4, e or a cylindrical section of larger diameter. The contact surface 4d can be freely inserted into the passage 3, h between the tabs 3a of the shells.

From the above remarks as well as from the drawing, it can be seen that the shells, which are used in pairs at the same time, are connecting elements between the pipes to be combined. and the fastening members or the axial rod. The distance between the lugs 31 and "the shells, for the purpose of mounting the various connection Egli Eder so determined that after making the association, the secure locking means of a key 5 takes place which the shape of a rider has, and whose legs 5M pass through slits% of the shells, which are close to the tabs % .

After insertion of the key 5 (Fig. 11 and 12) .aet% Full ** in is the space between the plates 3 4e constantly through the head, the portion 2a (or the end of the rod 1) and these wedge filled so daso the position of the tabs 3A and 3.2 of the two shells which are supported against each other by the mutual engagement of the projections and depressions #f is completely determined.

Rings 6 can be pushed onto the contact surfaces la at the ends of the rod 1. These form stops and serve to catch up with the game. One end of the rings abuts against an outermost puse 2e of the part or parts 2. The other end of each ring is held by a wedge 5 which is inserted through the openings 1d and through the slots % of the shells when the tubes or the like. Like * in the axial extension of the rod 1 are attached.

In a simplified embodiment shown in Fig. 13 and 14, the ends of the pipes to be attached or the like. T not with end pieces 4 provided but by compressing oder'auf other way directly so daso formed a Anlagefla "che Ta smaller diameter bildeng which directly into the passage 3 # b between the tabs% of the shells is introduced. The end Tb forms the retaining head The end of the section Tb can be closed by an attached, welded or flanged plate 7 .

The conditions and possibilities of use and the assembly of the node point according to the invention are readily apparent from the description and the drawings.

The following properties and advantages should be pointed out in particular; - The junction is made with a minimum of relatively simple parts and under conditions such that these parts are strong and have no weak dangerous sections. Manufacture, storage, procurement and use are therefore economical, convenient and simple.

.- The possibilities of shortening pipes or the like. by means of this junction can be regarded as unlimited in terms of the number as well as the directions that can be established and permit the establishment of the most intricate connections. On the one hand, the Befeatigungeglieder 2 can be attached in the required number and with the position required for the connection to be established around the rod 1 , and on the other hand, a certain number of tubes T or the like can be attached to each fastening member 2. be fastened in precise directions with a precisely defined position.

- The fastening and the alignment of the pipes T oodgl. in relation to the parts 2 in more frequently used directions and at certain more frequently used angles is facilitated by the fact that the radial ribs 2c are arranged in these angles, e.g. 90 0 - 45 0 - 30 0, corresponding angular positions or according to any other practical mounting angle . These ribs 2o pass through the arrangement between the tabs % in the slot 3d. LZulge of the sections 2a of the parts 2, angle information, for example by engraving or the like. be attached.

- the axes of the same at the ends of the rod 1 in the axial extension attached tubes T or the like, a small angular displacement may be given with respect to the axis of the rod 1, for example by mutual coordination of the game. In this way, for example, spherical or spherical cap-shaped arrangements can be produced.

While it is usually difficult to replace a new pipe or the like. to be inserted into an arrangement produced with the aid of nodes of known design, for which a node must generally be dismantled, it is possible with the inventive Motenstelle to easily attach one or more additional pipes or the like that were not originally intended tubes cooperating pairs shell 3 can be displaced axially with respect to the parts 2 or the stick 1. There are thus verschobent the shells and not Verbindungeknoten. the wedges 5 effect the secure locking of the assemblies.
