Tube set consisting of at least two coaxial tubes

This invention relates to joining of all kinds Pipe types with whatever diameter, which are arranged coaxially, in other words end-to-end. In particular concerns this invention the connection of pipes made of plastic, which consists of pipe pieces of constant diameter over the whole Length are formed.

The purpose of the invention is to make such a connection extremely easy, quick and economical way to realize.

Another purpose of the invention is to realize this connection in such a way that it can be disassembled very quickly can be, for example, to remove part of a pipe system.

Another purpose of the invention is to achieve that such connections by unskilled labor, that have received practically no training can be realized.

Finally, the subject of the invention is such

Merging under extremely economical conditions to realize.

The means disclosed by the present invention are in both permanent and temporary pipelines of Concern.

These various goals are achieved by the fact that a connection according to the present invention is characterized by the fact that the two adjacent ends of the drill to be joined have an outer crown which is formed by a hooking tape, such as a tape or braid with loops or a tape or braid with hooks of the type or any other suitable hook-on tape or braid and that a hooking band surrounds the aforesaid crowns at the same time.

The aforesaid crowns are connected to the aforesaid abutting ends of the drill hole to be connected through each known means, for example by gluing, connected.

The aforementioned, prepared in such a way drill or pipe parts are brought coaxially into contact with one another, and the two adjacent crowns are connected to each other by using one or more turns of a hooking ribbon or stranded wire.

If the aforementioned crowns are formed by a fabric with loops, the common hooking band becomes or wrapping of the crowns located next to one another can be realized in the form of a ribbon or braid

Hook pieces such as hooks, mushrooms or other suitable parts.

With a view to realizing the aforementioned wrapping over a greater length than the circumference of the aforementioned crowns, this wrapping is formed by a braid or ribbon, one side of which has loops and the other side has hooking parts (back to back).

The width of the crowns and the envelope is determined by the resistance to tearing away, in other words by the axial influences or the possible bending forces.

According to a very special feature of the invention the surrounding tape or wrap will be formed by a two-sided hooking tape that has good longitudinal elasticity. For certain applications, the hooking tape will be designed in such a way that it has very good longitudinal elasticity and very high transverse resistance. For this purpose, the aforementioned surrounding band can be shaped, for example, in such a way that all or some of the weft threads have minimal elasticity or elongation. to metal threads, for example, could be used for this purpose.

The connection according to the invention can be completed with additional or supplementary arrangements the purpose of increasing the resistance to traveling away, in particular the resistance to unintentional drifting apart to increase adjacent pipe parts.

The connection can also be completed by any means that is suitable for ensuring or improving its tightness.

As a non-restrictive example, the next-

A version is described with reference to the attached Drawings) in which:

Figure 1 shows a side view in partial cross-section of the end of two pipes to be joined;

Figure 2 shows a part on a larger scale, which is indicated in Figure 1 by F2;

Figure 3 shows a cross section along the line III-III in Figure 2;

Figure 4 is a side view with partial cross-section the connection according to the invention shows:

Figure 5 shows on a larger scale the part that in map t is denoted by F5;

Figure 6 shows a cross section according to the line VI-VI in Figure 5}

Figure 7 shows a cross-section of a tape that is particularly suitable for the execution of connections according to the invention.

In these figures the ends of two pipes or pipe parts to be connected according to the invention are represented by 1 and 2. On the adjacent ends of these tubes, two hook-on crowns 3 or \ "are attached, for example by gluing, which in this case are formed from a ribbon or strand of astrakhan, velvet or any other fabric.

The width L of the aforementioned crowns is determined in relation to the required axial tensile strength. It is understandable that this strength is directly dependent on the number of hook components.

The two pipe sections prepared in this way · 1 and

are brought into contact coaxially with each other »after which the aforementioned crowns 3 and 4 by a common band or strand 5 * the latter should! have a width Ll which is equal to or approximately equal to twice L.

For certain applications, especially for light pipe systems with little influence, a single thickness of the The aforementioned winding S over the entire circumference of the adjacent crowns 3-4 can be regarded as sufficient. In general however, this tape or braid 6 is realized in this way that the underlying part is overlapped sufficiently so that in such a case a double-sided tape or stranded wire has to be used, one of the sides of which is designed in such a way that it has hook components, while the has hooking components on the other side. A connection will therefore be made with the help of such a winding can, which is formed from several turns.

The connections realized in this way will generally have a sufficient tightness, all the more so as in numerous applications such pipes are intended to convey dry powdery or core-shaped products or the like. However, this connection also makes it possible to achieve a perfect connection of pipes intended for the transport of liquids or semi-liquids. As shown schematically in Figure 7, a layer or thickness 6 of impenetrable material ^{can be attached between the two sides 5 f} -5 "of the tape or braid 5, with
