Description

Description: FIELD OF THE INVENTION This invention relates to a frame for transporting and supporting tubes.

Prior Art Two publications for pipes are known from the publication (Pamflett) of the Siguma Chemical Company of Hiewston, USA. The outer (lower and upper) and middle parts have a frame part with a cutout for inserting a pipe. One frame uses a relatively light steel frame, which has a steel / rubber cushion for the pipe, which is fastened by a number of screw bolts that must be threaded between the cushions. Assembly is very time consuming due to the large number of screw bolts required. And the formwork used is not stable enough. In the other frame, the frame part with the shape is used. These frame parts are provided laterally with bayonet joints and are brought together by a strip of steel or plastic which is guided around the frame parts and the tube bundle. Also in this case, the assembly is complicated. This is because all the frame parts must be put together once, and then the band must be wrapped around the entire frame and tightened together. However, the rigidity is still not so high, and therefore there is a risk that the band will be broken when a large stress is applied during transportation and transshipment.

Therefore, an object of the present invention is to assemble the frame defined in the superordinate concept of claim 1) easily and in a short time,
The construction is to enhance the stability of the frame portion and the entire frame. Another object is to improve the tube support and make the frame part simple and inexpensive to manufacture.

Solution to Problem The problem is solved by the features described in claims 1) and 12) to 14).

The construction according to the invention makes assembly and disassembly of the frame significantly easier and easier and improves the stability of the frame.

Advantageous and advantageous developments are characterized in the other patent claims.

Particularly, by the development according to claim 2), which is related to the structure described in claim 10), it is possible to protect and dispose the part of the lock rod which is the connecting member of the frame, and the hollow frame The stability of the part is further increased, and the part of the lock rod provided in the recess is more easily reached.

Holes or cutouts are provided on the side of the upper frame to connect the upper frame to the lower frame via the lock bar. The provision of the hole has the advantage that the locking rod will not stick out laterally. Of course, if that happens, the upper frame must be fitted to the lock bar. Providing the notch makes handling easier. In that case, of course, there is a danger that the rock rod will lie sideways from the top frame if an extremely large load is applied.
In order to eliminate this drawback, there is a structure described in claim 3).

In this way, the rigidity and stability of the upper frame is not adversely affected.

Another advantageous configuration according to claims 1), 4) and 5) facilitates the mounting and dismounting of the locking rod from the bottom frame.

An advantageous and advantageous embodiment of the locking rod is claimed in claim 6).
It is described in.

In order to make the intermediate frame more stable, claim 7) describes advantageous developments.

When the intermediate frame has substantially the lengths of the lower end frame and the upper end frame, the intermediate frame is provided with the side cutouts as described in claim 8).

If the intermediate frame has the advantageous configuration according to claim 8), the cutout can be omitted.

In order to mount the tube completely, permanently and reliably in the frame according to the invention, the construction according to claim 9) is implemented.

With this configuration, weakening of the intermediate frame is prevented.

The injection or drawing method is carried out by using aluminum or plastic as the material of the frame.
