• Plate-like, formed from extruded profiles Composite profile, especially scaffolding plank "

Plate-like composite profiles made from extruded hollow profiles are known, for example, in wagon and facade construction. The individual extruded profiles are positively pushed into one another, hooked into one another or welded to one another.

- 4th

Welded composite profiles, which have high strength values, cause high manufacturing costs. Form-fitting Profiles pushed one into the other in the longitudinal direction are difficult to use when the profiles are long Assemble tolerances. Profiles hooked to one another at their longitudinal edges generally only have low strength values, at least when subjected to transverse loads. Such educated Plate-like composite profiles are therefore not suitable for use under corresponding transverse loads.

The object of the invention is to propose a plate-like composite profile made of extruded profiles, which Can be easily manufactured in terms of manufacturing technology and can withstand high loads across the plane of the plate.

The object of the invention is achieved with a composite profile all features of claim 1.

The composite profiles according to the invention consist of extruded profiles which are mounted against one another from their narrow sides will. The groove-web strip connection leads to an initially sufficient clamping or clipping, so that in this fixed position in a simple manner a final positive compression of the connection points can be carried out.

In order to prevent splitting corrosion, it is advisable to glue the grooved strips and web strips, which are connected to one another in a form-fitting manner, to one another in a sealing manner.

The plate-like composite profiles according to the invention have a high bond strength. The connection area is not critical, so that such composite profiles can also be used as scaffolding planks can be used where a high transverse load can be assumed.

Appropriately designed extruded profiles are specified with claims 2 and 3. Certain accumulations of material the delimitation webs of the groove strips lead to a favorable compression and clasping of the appropriately trained Saddle strips. In particular, the design of the groove limiting webs and the web strips specified in claim 3 leads to a clip-like hooking of the connecting elements during assembly.

The invention is explained in more detail below on the basis of an illustrated embodiment. Show it:

the cross section of a plate-like composite profile formed from two extruded profiles,

If and

2-4 enlarged sectional views

of area A in Fig. 1 during the individual connection phases.

The composite profile shown in Fig. 1 consists of the two interconnected extruded profiles 1 and 2. The The first profile 1 is formed by the upper chord 11 and the lower chord 12, which are formed by the webs or the walls 13 and 14 are connected to each other. In a flush continuation, the groove strips 15 are directed outward on the belts 11 and 12 and 16 integrally formed.

The second semi-hollow extruded profile 2 also consists of an upper chord 21 and a lower chord 22, which are connected to one another by the web. In continuation of the belts 21 and is each inwardly offset a web strip 24 and 25 formed, which at 'the connection in the corresponding groove strips 15 and 16 of the profile 1 engage.

The shape of a groove strip 16 before the connection can be seen from FIG. The not yet deformed groove bears the number 18 ·. The groove bottom is denoted by 181 ^f , the outer groove limiting web, which is essentially not deformed, bears the number 184, while the inner groove limiting web has the number 182 '. A material accumulation 183 'is provided at the end of this inner groove delimitation web 182'.

The as yet undeformed web strip 25 'on the lower chord 22 of the second extruded profile 2 can also be seen from FIG. The web 251 * of the bar 25 'is about the thickness of the groove limiting web 184 cranked towards the inside. At its end, the stegleisto has an inwardly directed accumulation of material 253 '. On the outward facing side is an edge 252 is formed, which latches on the corresponding bead 185 of the groove limiting web 184 during the connection.

As Fig. 3 shows, the two profiles 1 and 2 are assembled against each other, while the web strips 25 'snap to the Groove strips 16 and 15, respectively. In this assembled position, the two profiles 1 and 2 are already precisely positioned relative to one another fixed.

The step of form-fitting pressing now takes place the groove strips and the web strips received therein in the transverse direction. For this purpose, in the second extruded profile 2 a drawing mandrel (not shown) is pulled through, each of which supports the slot delimitation webs 182 * with the material accumulation 183 * pressed against the web strips 25 ', the accumulation of material 253' being positively enclosed. It is created in the process the connection according to FIG. 4. In the grooves 17 and 18 of the groove strips 15 and 16, the web strips 24 and 25 are positively received. The grooves now carry the digits 18, their borders the numbers 182 and 184. Recognizable

is the deformed accumulation of material 183. The now modified Mutboden bears the number 181. The deformed web the web strip 25 bears the number 251.

The pressing can also take place in other ways. For example, the composite profile on the fixed η mandrel be pulled by.

In order to avoid crevice corrosion, the groove strips and web strips, which are pressed together in a form-fitting manner, can be glued to one another in a sealing manner.
