[0049] FIG. 1 shows a cross section of a first example of the structural profile in a flat embodiment in which the outer contour 1 has a longitudinal side 2 with a longitudinal-side groove 4 and a transverse side 3 with a transverse-side groove 5. As shown in FIG. 1 and represented by the dotted line, the longitudinal centre axes of the grooves 4, 5 are located in a common groove plane corresponding to the longitudinal centre plane 8 of the structural profile. In this embodiment, the longitudinal side 2 additionally has a further longitudinal-side groove 4. Furthermore, in this embodiment the outer contour 1 has a further transverse side with a further transverse-side groove (in FIG. 1 without reference numeral).

[0050] The groove cross section 6 is partially highlighted in the figures by an angular enclosure illustrated in a dotted line. In this embodiment, the groove cross section 6 of both the longitudinal-side grooves and the transverse-side grooves 5 has a flat groove base 11 and spaced surface sections 9. In the first embodiment, all grooves 4, 5 have the same groove cross section 6 with a groove base 11 and spaced surface sections 9; nevertheless; for reasons of clarity, only the transverse-side groove 5 is provided with the reference numerals 6, 9 and 11.

[0051] FIG. 2 shows a cross section of a second embodiment. It is an embodiment with a medium profile height. Here, the groove cross section 6 has an upper section 4b and a lower section 4a.

[0052] The upper section 4b has a rectangular cross section and additionally a T slot. The lower section 4a is connected to the upper section and has a round cross section. The longitudinal centre axis of the transverse-side groove 5 and the longitudinal centre axis of the lower section 4a are positioned both on the longitudinal centre plane 8. In addition, the descriptions in FIG. 1 apply accordingly to FIG. 2.

[0053] FIG. 3 shows a cross section of a third embodiment. It is an embodiment with a high profile height. The lower section 4a is connected to the upper section 4b of the longitudinal-side groove 4, as it is the case in the design of the second embodiment with the medium profile height. The longitudinal centre plane 8 of the lower section 4a and the longitudinal centre axes 8 of the transverse-side grooves 5 are in a common plane. Compared to the embodiments in FIG. 1 and FIG. 2, the lower surface section of the spaced surface sections 9 is extended towards the lower section 4a. The diameter of the lower section 4a is increased in comparison to the second embodiment so that fasteners with M8 screw size can be used in the lower section 4a according to FIG. 3. Apart from that, the geometry of the cross section is essentially the same as in the second embodiment. In addition, the descriptions in FIG. 1 apply accordingly to FIG. 3.

[0054] FIG. 4 shows a cross section of a structural profile the front end of which is mounted on one longitudinal side of a support profile. The structural profile corresponds to the third embodiment according to FIG. 3. In this design, the fixation is achieved by the use of four screws 16 in four anchor sleeves 14. The thread outer diameter of the anchor sleeves always corresponds to the inscribable circle 7. As the diameter of the lower sections 4a is increased, the anchor sleeves 14 and the screws 16 in the lower sections 4a of the longitudinal-side grooves 4 also have a greater diameter than the anchor sleeves 14 and the screws 16 in the transverse-side grooves 5. In the transverse-side grooves 5, five points of contact 10, which are shown in more detail in FIG. 6, are created in the cross section. FIG. 4 shows in particular that, due to the arrangement of the longitudinal centre axes of the grooves 4, 5 in the longitudinal centre plane 8 of the structural profile according to the invention, the screws 16 of all grooves 4, 5 can engage in one and the same longitudinal-side groove of the support profile.

[0055] FIG. 5 is an isometric exploded view of a mounted structural profile according to FIG. 4. The four anchor sleeves 14 are screwed into the front end of the structural profile without projection and fixed with screws 16 to the profile anchor 13, which is previously inserted in a longitudinal-side groove of another structural profile, referred to as a support profile in this specification. A fixation pin 12 facilitates the installation of the structural profile by pressing the profile anchor 13 against the base of the longitudinal-side groove of the support profile and thus prevents it from getting out of place along the longitudinal-side groove during assembly.

[0056] The construction also allows to swivel cross braces into existing frames at a fixed distance between two support profiles, wherein the frame does not have to be opened.

[0057] FIG. 6 is a detailed view of the cross section in which the circles 7 are inscribed, in particular to demonstrate the points of contact 10. For clarification, the points of contact 10 are shown here in a special manner and each point is highlighted by an arrow. The diameter of the inscribed circles 7 corresponds approximately to the internal thread diameter of the anchor sleeves 14. The points of contact 10 illustrate the points where the thread of the anchor sleeves 14 works its way into the material of the structural profile.

[0058] In this embodiment, the structural profile is designed in such a way that four points of contact 10 to the groove walls are formed in the transverse-side groove 5 and in the upper section 4b of the longitudinal-side groove 4. In addition, a further point of contact 10 to the groove base 11 is formed in the transverse-side groove 5. The high number of points of contact 10 provides a firmer anchorage of the anchor sleeves 14 after being screwed in, as the force is distributed over five points of contact arranged at great angular distances. The lower section 4a of the longitudinal-side groove 4, which corresponds to a central borehole, even allows to use more than three-quarters of the circumference of an inscribed circle 7 as a contact surface for anchoring the anchor sleeves 14. This design makes the anchorage very stable on the one hand, and on the other hand the greater diameter makes it possible to use more robust screws 16.

[0059] FIG. 7 is a detailed view of the cross section of the structural profile, in which cladding panels 15 have been inserted into the longitudinal-side groove 4 and transverse-side groove 5 of the outer contour. The spaced surface sections 9 are always arranged in a common plane and the planes of the spaced surface sections 9, positioned opposite to each other in a groove, are parallel to each other. Thus, the distance between the spaced surface sections 9 positioned opposite to each other in a groove is also constant. The panel material can thus be pushed into the grooves with a positive fit and is clamped and stabilized against buckling in the sense of Euler's formula.
