Pig. 8 'in an exploded view cut the

left half of another U-profile that . is composed of individual elements.

The exemplary embodiment according to FIG. 1 is approximately on a scale 1: 1 shown. A U-profile made of plastic Io demonstrates on the two upper limb areas inwardly facing approaches 18 that have a multiple puncture to have. Initially, the approaches l8 serve to support and hold the cover 11. It is only indicated schematically. that the lid 11 has two protruding strips with one on its underside in the region of its edges has such a profile that the lid is held in place in the readily apparent manner.

In addition to the two side walls of the U-profile, the two approaches 18 downwardly open grooves 13, the along with. similar grooves Ij5 in the bottom of the profile next to the side walls form guides for sheet metal or plastic strips 15 to be inserted. It's in Pig. I only such a strip 15 is shown; on the right side such a strip also belongs to the profile.

The bottom of the profile has inwardly protruding and hook-shaped profiles designed to each other - and also continuously formed projections 14, which also provide a guide for a reinforcement to be inserted and / or represent connection strips 15. With 12 are in the area of the side walls on the floor Designated profile webs, which limit the lower grooves 13 on the inwardly facing side.

One is dashed to the right of the center line M Half of an installation box 16 is shown. To the left of

the center line, a bracket 17 is shown with the dotted lines, which approximately the shape shown in FIG Has. Such a bracket has cranked port sets 17a at its ends, with which it can be inserted into the two upper grooves 15 can engage on the underside of the profile parts 18. This bracket is used, for example, in the installation channel that is formed by the interior of the profile, to secure laid cables against falling out or against shifting. In particular, one becomes such a bracket Use if you turn the profile 180 degrees and use it as an installation duct on the ceiling of a room.

The metal or plastic strips 15 on the sides of the Profiles have a double function: they serve to stiffen the profile against loads from above, which is important when laying the installation duct in a drivable floor. Note that the contact surfaces for the cover 11 at the top Profile approaches 18 almost exactly over the sheet metal strip 15 are located, whereby an introduction of forces acting on the cover in the sheet metal strips 15 is ensured at all times is.

In Pig. 2 is a plan view and is a highly schematic one Corner connection of two profiles Io and Io according to FIG. 1 shown. The two profiles were cut at the corresponding point after the miter line G at 45 degrees.

^{Sheet metal strips 15 and I5 1} bent at an angle are now inserted into the guides Ij5, for example of one profile Io, as shown in FIG. After this has been carried out, the guides 13 of the other profile lo * are pushed onto the surfaces of the two which face downward in FIG. 2

Reinforcement or connecting strips 15 and 15 '-

The arrangement according to FIG. 3 likewise shows, in a highly schematic manner, a butt joint of a profile Io to one side of a second profile lo ¹ . The cutting line S stands for a window-like recess which has previously been worked into the corresponding side wall of the profile Io '. Connecting strips 15, which are bent at an angle and then point upwards in FIG. 3, are pushed into the two guides 13, which are thereby exposed in the profile. The second profile Io with its guides 13 is now pushed from above (always in relation to the plane of the drawing!) Onto the protruding parts of the bent strips 15 and 15 ¹ . "A T-shaped connection between two profiles that are identical in this case has thus been created in a simple manner.

With regard to the connection possibilities according to FIG. 2 and J>, it should be noted that two profiles can also be connected to one another in the manner shown, which have a different width. Each time the corresponding cutting lines G or S are produced, the guides IJ are exposed in the two profiles to be connected, so that connecting or reinforcing strips 15 and 15 'which are bent at the correct angle only have to be used accordingly.

While Figures 2 and 3 di. ^e show the connection of two profiles, so to speak, from above in the orientation according to FIG. 1, the connection of two profiles is shown in a schematic representation in FIG. 4, which - with reference to FIG. 1 - would be seen from the right or left. Ss is the connection according to Fig. '+ To the connection of a profile lo, which, for example, is flush with the

Floor surface is laid in a room floor, with a profile Ιο * leading upwards in the wall where the floor and wall meet. The miter line G is compared to the arrangement according to FIG. 2 in a corresponding manner cut rotated plane. Two connecting strips, bent in an L-shape in this case, are then carried out 15 * in those exposed by the miter cut Guided tours IJ. One can now refer to the above Leg of the L-shaped connecting strip "the other Slide open profile.

FIG. 5 shows, in a highly schematic manner, an installation channel, in section, which was produced from a profile with twice the width (based on the profile according to FIG. 1). The profile lo ^ft is covered with a correspondingly double-wide cover 11 ″ ". The two upstanding side flanges or legs of the U-profile again have the schematically indicated guides for connecting or reinforcing bands that are not shown. Corresponding guides for two adjacent ones are in the bottom The cast-on Profi If extension 14 * protrudes from the floor and has a longitudinally running slot that is open at the top, into which a partition, indicated schematically at 19, can be inserted. Such a partition divides the channel profile into two Halves, which is required, for example, when laying high-voltage and low-voltage lines * In addition, the cover can be supported in the middle by the partition 19.

The illustration according to FIG. 6 schematically shows the arrangement of two profiles next to one another according to FIG. 1 In such a way again that you practically have a double

so great channel gets. In this case, there is automatically a partition through the adjacent ' upright bars in the middle.

At this point it should be pointed out that one too Two adjacent profiles, which are arranged approximately according to Fig. Connect with a profile at an angle can, with only the miter line not the bisector of the center lines of the to be connected Profile is. It is always important that the cuts on the ear surfaces of the profiles to be connected are of the same length are, whereby automatically at least two ■ connecting strips bent approximately according to FIG. 2 form a connection of profiles.

In Fig. 7, the bracket 17 explained is shown in section. Expediently whored to the equipment of such Installers who lay ducts also have a number of continuous flat cover plates that form the profile according to Fig. 7, and which would therefore have to be used in exactly the same way as the retaining brackets 17

In Fig. 8 is a further embodiment of a profile shown schematically, namely only the left half of a U-profile in relation to the plane of FIG. 8. To the right from the representation one would have to imagine a center line M as in FIG.

In this embodiment, the profile consists of several Binzelprofile, their assignment and assembly without further ado from Flg. 8 emerges. Here one can assume that, for example, the flat strips 26 of a corresponding width replace the plastic walls to be reinforced of the profile according to FIG. 1. Bine special

The problem here is that corresponding reinforcing and connecting strips 25 are inserted into the same grooves 2j5 on the connecting profiles 2o and 24, into which those strips are to be inserted which form the actual flat parts of the U-profile. In Fig. 8 a somewhat groove hinterschnitte- ne is shown at 22 schematically, which serves the cover for receiving the locking rib. Fig. 8 also shows particularly clearly that the main support surface 21 of the lid is practically ge exactly in the plane of the reinforcing strip 25 in the upstanding side edges of the profile . In this way, forces exerted by the cover are transmitted to the reinforcement strip 25 in the direction in which it has the greatest load-bearing capacity.

Of course, in the embodiment according to Fig. 8 be provided that the profiles are made of plastic or plastic-coated metal. Man can also be used instead of two strips 25 and 26 lying next to one another in the manufacture of, for example, the Sei-i the walls of the. ü-profile use a single layer, which must then be correspondingly strong. Obviously one can use two profiles composed in this way from individual profiles according to FIGS. 2 to 4 and the others Connect indicated connection types with similar profiles, whereby the. corresponding strips 25 and 26 if necessary. can be bent together to create a connection according to Pig. 2 or 3 to make.

Of course, it is possible, in a manner not shown in FIG. 2, to also use the bottom ribs 14, not shown, and a correspondingly L-shaped connecting plate to establish the connection.

Overall, the invention creates a simple and cheap Profile to be produced which, together with the corresponding reinforcement strips, absorb those high loads can occur with the recessed arrangement in traversable floors. The cover 11 lies with his upper surface in the plane of the soil surface. He can be highly stressed if he can only do enough by himself is rigid. If the lid has to be relatively wide, see e.g. Pig. 5, then you can put the lid in the middle the way shown there.

You only need. · A profile "for the production of relative resistant installation ducts in floors and the mechanically hardly stressed installation ducts in Ceilings or walls. It is to be regarded as particularly expedient that these profiles can also be used for different purposes Use and with different loads with each other can connect in a simple and secure manner.
